Opis:

The World Meteorological Organisation predicts an increase in average annual temperature. As a result of climate change in Slovakia, one can expect changes in the distribution of precipitation and moisture availability, changes in the temperature availability of crop production, changes in wintering conditions, and many others. The aim of this work was the analysis of agroclimatic indicators for the period 1961–1990 and 1991–2020. The results showed an increase in the sums of temperatures in the growing season. Also, the increase in temperature resulted in a change in the zones of the agroclimatic indicator of moisture and the agroclimatic indicator of wintering. The zones have been shifting to higher altitudes throughout Slovakia.

Opis:

The paper deals with the problem of road noise pollution in the context of spatial development. The analysis was motivated by the changes in the permissible noise levels that occurred on 1 October 2012 and the high urban pressure on areas located along the main traffic routes. On selected examples of sites located in the districts of Bemowo and Białołęka in Warsaw, the location of land functions is shown on the background of the course of isophones of acceptable noise levels. The analysis was based on data from acoustic maps for Warsaw developed in 2012 and 2017, planning studies, database of topographic objects and current state of development. Based on 20 features and 9 surface and quantitative indicators, determined using ArcGis software, the degree of road noise pollution in planning terms was shown. The analysis has been demonstrated that the changes in legislation have resulted in the acoustic “freeing up” significant areas along the main road, express and accelerated main roads and a reduction in the number of buildings that were considered to be at risk of noise pollution by the law before 2012. The acoustic release indicators for the general area were in the range of 0.71–0.74 for LN and 0.56–0.74 for LDWN. In relation to acoustically sensitive areas the results were in the range of 0.81–0.84 for LN and 0.64–1.00 for LDWN.

Opis:

Public sector has been appointed to carry out tasks of general interest. These tasks are usually non-profit, which causes that they are financed from public funds. In such circumstances, the important point is that the choice of tasks for execution was made rationally and after carrying out a multifaceted analysis. Measurement issues of efficiency gain particular importance in the management of both municipal finance, as well as the whole of the public sector in connection with the implementation of the new public management concept. The evaluation of the financial management is difficult. It requires taking into account many different variables. The selected set of characteristics that describe the financial economy, should, as far as possible, in a full and comprehensive way study the phenomenon. The purpose of the study is to examine whether the assessment of the effectiveness of the financial activities of local government can be used as a synthetic indicator, whose structure depends on the adopted methodological assumptions. The selection of the final variables to the structure of the synthetic indicator includes variables describing the financial economy. The final set of diagnostic variables was created taking into account the established substantive, formal and statistical criteria. The characteristics of spatial units is based on the arithmetic mean, standard deviation, coefficient of variation, the asymmetry factor and the correlation coefficient. Taking into account formal conditions, complete and available measurable variables were selected Linear ordering methods allow to determine the hierarchy of objects or arranging them from the object being the highest in this hierarchy to the object being the lowest. Linear ordering enables multi-dimensional analysis of the phenomenon. Synthetic indicator gauge takes values in the range [0; 1], the higher the value of this index the better situations of the object. Rural communes of Świętokrzyskie Voivodeship are the subject of the research. Synthetic indicator structure consisted of the following variables: value of own income, value of the revenue from tax return, value of the revenue from CIT, value of tax revenues, value of funds obtained from external sources, value of current expenditure, value of property, value of expenditure on welfare spending and value of expenditure on public administration. Communities of Świętokrzyskie Voivodeship continued to show a large variety in terms of the level of financial health. On the one hand, it was possible to distinguish a group of communities with high level of financial health, on the other hand, the communities with a very low rate.

Komfort termiczny jest, obok m.in. jakości powietrza wewnętrznego, poziomu hałasu, czy np. wystroju wnętrza, istotnym elementem pozytywnego odbioru otaczającego środowiska. Z uwagi na stale wydłużający się czas spędzany, zarówno w życiu zawodowym, jak i pozazawodowym w pomieszczeniach, w których warunki środowiska są sztucznie kształtowane przez urządzenia klimatyzacyjne, niezbędne jest zaprojektowanie parametrów powietrza wewnętrznego w taki sposób, aby przebywanie w nich nie prowadziło do zaburzeń zdrowotnych (np. zespół chorego budynku - Sick Building Syndrome). W artykule przedstawiono metodę oceny pomieszczeń pod względem komfortu cieplnego, na podstawie normy PN-EN ISO 7730:2006: Ergonomia środowiska termicznego. Analityczne wyznaczanie i interpretacja komfortu termicznego z zastosowaniem obliczania wskaźników PMV i PPD oraz kryteriów lokalnego komfortu termicznego. W sposób praktyczny zilustrowano prowadzenie takiej oceny na przykładzie pomieszczenia biurowego.
Thermal comfort is in addition to, i.a., indoor air quality, noise level, and interior design, an essential element determining the way the surrounding environment is perceived. In light of the fact that time spent both professionally and privately in buildings in which environment conditions are shaped by air conditioning is increasingly longer, it is imperative to design such indoor air parameters which will help to prevent potential health problems (e.g. the Sick Building Syndrome). This paper presents assessment methods of buildings thermal comfort in compliance with the PN-EN ISO 7730:2006 standard "Ergonomics of the thermal environment. Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria". A sample office space illustrates how such an assessment can be made.

The following article describes the effect of combustion chamber leakage of piston engine on the quality of its performance. To make a diagnosis of combustion chamber tightness, only such parameters were selected which are characterized by high information value and are closely connected with its defined structure. For this reason such connections are unmistakable, which results in making the right diagnosis of combustion chamber tightness of piston engines. Special attention was paid to the fact, what consequences, combustion chamber leakage, can cause to the piston engine performance. The most dangerous for the engine efficiency is the leakage of combustion chamber. The leakage of combustion chamber brings about the change of such engine parameters as pressure of suction, pressure of final compression and burning and the change of exhaust gases composition, which effect on the engine power and on fuel consumption. Condition of piston rings and their influence on gas pressure in combustion chamber has also been characterized. Pressure of gases taking place in engine cylinder and their connection with leakage of combustion chamber have also been described. The article also exposes random character of combustion pressure in engine cylinder. Besides, the errors of indicator diagrams together with mapping error position GMP have been mentioned too. Reliability of diagnostic parameters of technical condition of combustion piston engines obtained on the basis of developed indicator diagrams has been defined. Such diagram must be made on the basis of measurements and statistic analysis of pressure parameters in correctly adjusted engines, being in perfect technical condition, and not on the basis of measurements obtained in the engine test bench of a new engine. Bad technical condition, especially leaks in its cylinders causes power differences in engine arrangements, which endangers its safe exploitation.

The following article describes parameters of developed indicator diagrams concerning piston combustion engine of ship main propulsion, which can be used to assess its technical condition. To make a diagnosis of the engine combustion only such parameters should be selected which are characterized by high information value, being closely connected with its one defined structure. This is the cause why such connections are of unmistakable character, which allows to make the right diagnosis of technical condition of piston engine. Special attention was also paid to the consequences of diagnostic symptoms qualification from developed indicator diagrams of ship propulsion engine working in different conditions. Deflection of average indicated pressure caused by inappropriate engine performance could be caused by: 1) faulty adjustment of injection pump; 2) leaky combustion chamber, 3) bad technical condition of injection apparatus and the loading air system. Wrong technical condition of the engine caused by a leaky combustion chamber brings about a decrease of its performance. Untight combustion chamber causes the change of such parameters as, suction pressure, pressure of final compression and burning, as well as, the change of exhaust gases composition, which influences the power of the engine and fuel consumption. It has been mentioned what gas pressures of working process in engine cylinders are connected with an untight combustion chamber. Random character of burning pressure course in engine cylinder has also been paid attention to. Reliability of diagnostic parameters of piston engine technical condition received based on developed indicator diagrams have been determined. Diagnostic symptoms have been defined, basing on measurements and statistical analysis of pressure values in the cylinders of properly adjusted engines being in excellent technical condition and not based on measurements received in the engine test bed of a new engine.

To introduce the special issue this paper reviews the use of protists as bioindicators. Seven key advantages of protist bioindicators are highlighted, namely: environmental sensitivity, functional importance, distribution, size and numbers, response times, ease of analysis and preservation potential. Protist bioindicators have been used in a wide range of contexts from ecosystem restoration to fire history, and particularly environmental pollution. Most major protist groups have been used as bioindicators with diatoms, foraminifera and testate amoebae particularly widely studied. To increase uptake of protist bioindication techniques in routine environmental monitoring technique development should consider the needs of stakeholders from an early stage. Papers in this special issue reflect the diversity of both protist life and possible bioindicator applications.

Opis:

Poverty is a serious problem in Slovakia, and it is concentrated in a few regions. The aim of this paper is to capture the spatial differences in poverty in order to identify the poorest districts and to point to the change in the development of poverty in regions during one decade (2001–2011). It was an important period, because it was when Slovakia joined the EU (2004) and the euro zone (2009), that the financial crisis appeared. Our approach to the topic of poverty is based on an aggregated poverty indicator. The indicator reflects three kinds of risks and a broad spectrum of poverty aspects.

Opis:

Ecological indicator values (EIV) are a commonly used tool for assessing habitat conditions in various ecosystems. They are relatively rarely used for the analysis of epiphytic communities, which results from objective difficulties in the study of this group of organisms in full height gradient on settled trees. Windthrows provide a rare opportunity to fully analyse the biota diversity of epiphytic bryophytes and lichens. The aim of the study was to determine and compare the EIV variability for bryophytes and lichens in the vertical gradient, from terrestrial to different epiphytic exposures. The fieldworks were carried out on two windthrow areas in the Kampinos National Park (central Poland). A set of floristic lists was prepared within five distinguished parts of trees (trunk base, lower trunk, upper trunk, lower crown and upper crown) and three parts of their uproots (pit, bottom root plate and top root plate) for three species (oak, birch, pine). Ten individuals of each tree species were selected. The average values of five ecological indicator values (light, temperature, continentality, humidity and acidity) were calculated within the examined parts of trees and their uproots. The significance of differences between bryophyte and lichen EIV within same parts of trees and their uproots was checked using Wilcoxon paired test. The significance of differences of EIV calculated for bryophytes and lichens pulled together between distinguished tree and uproot parts were checked with Kruskal−Wallis or Mann−Whitney tests. Ordination of researched parts in terms of their EIV was carried out using NMDS method. The values of individual EIV obtained with the use of bryophytes and lichens for the examined parts of trees and their uproots differed significantly in most cases. The values of temperature and continentality in most cases were significantly higher for lichen, which may indicate the need for additional calibration of these indicators for these groups of organisms. The use of both groups of organisms in bioindication has increased the quantity and quality of available ecological information. The research confirmed the usefulness of ecological indicator values as a tool for analysing general habitat conditions in forest ecosystems.

Opis:

The steel and iron industry production is dedicated to serve other industries mainly. This makes the exercise of demand forecasting different than for consumer goods. The common sense says that demand fluctuations are influenced by general economic soundness. An attempt was made to address the question of improving forecast’s accuracy by adding a business cycle indicator as an input variable. The SARIMAX model was applied. Including a business climate indicator improved model’s performance, however no co integration is observed between the two series.

Opis:

W artykule przedstawiono analizy wybranych wskaźników zdrowia publicznego monitorowanych przez Eurostat w ramach strategii zrównoważonego rozwoju. Analizy oparto na danych pochodzących z baz Eurostat (on-line) i INSEE (on-line). Dane przedstawione w tabelach i na rysunkach prezentują dynamikę zmiennych. W wyniku przedstawionych analiz można wnioskować, że we wszystkich rozpatrywanych obszarach zdrowia publicznego istnieje znaczne zróżnicowanie pomiędzy krajami UE. Niemalże we wszystkich wymiarach poprawiają się wskaźniki zdrowia publicznego mieszkańców Unii: zmniejsza się dystans między oczekiwaną długością zdrowego życia mężczyzn i kobiet; maleje przeciętna śmiertelność z powodu chorób przewlekłych i samobójstw; nie wzrasta wskaźnik narażenia ludności miejskiej na zanieczyszczenia powietrza; mniejsza część ludności deklaruje uciążliwość z powodu hałasu.
The paper presents analyses of selected indicateurs from public health area monitored by Eurostat in the framework of the sustainable development strategy. Analyses are based on data derived from databases of the INSEE and the Eurostat. The data shown in tables and figures present the dynamics of variables. It could be concluded that in all are as of public health, there is considerable variation between countries in the EU. Almost in all dimensions of public health of the EU population improves: the gap between the healthy life expectancy of men and women is reducing, the average mortality from chronic diseases and suicide is decreasing , the urban population exposure to air pollution does not increase, a nuisance because of the noise is declared by smaller part of the population.

Opis:

The paper analyses the current offer of combustion pressure sensors for use on marine engines under operating conditions, methods of data acquisition, methods of determining TDC position and methods of obtaining diagnostic information from the indicator diagrams. Terms of continuous work on marine engines themselves only: new ABB cylinder pressure sensor, the piezoelectric sensors from KISTLER and AVL companies, but with limitations, the main ones being stability at high temperature. Another important issue for the accuracy of mean indicated pressure and heat released characteristics determination is referred to TDC position on the indicator diagrams. TDC is appropriate thermodynamic point, it is hardly determinable in the presence of interference and lack of sufficient information – but is used, for example in ABB solution. One of the sources of diagnostic information is to analyse trends in some parameters, which, unfortunately, is very difficult in environments with varying engine loads. Further progress in the diagnostic use of indicator diagrams should be associated with the use of the heat released characteristics and the net internal efficiency, which as shown by the results of preliminary tests can be used to assess the accuracy of the injection and combustion of fuel, including gas fuel. Supplementing these methods may be the use of vibration and noise to detect certain malfunctions.

Opis:

The study is aimed at assessing international competitiveness of Polish exports on a selected market. The research was conducted at sectoral level. The research method employed is the attractiveness and position indicator (AP-indicator). The AP-indicator adopts the portfolio models approach. The method enabled to quantify target market’s attractiveness and the competitive position of Polish exports on that market. The research is based on EUROSTAT statistics and covers the period of 2010-2018. According to the results, all the widely defined categories of products delivered by Polish exporters to German may be considered as competitive. The most promising part of Polish exports on the considered market are the SITC 0+1, SITC 5, SITC 6+8, and SITC 7 class, characterised by the extraordinary market growth and high exports’ dynamics. The study is dedicated only to assessing competitiveness. Explaining the drivers of the competitiveness is beyond the scope of the research.
Badanie ma na celu oszacowanie konkurencyjności międzynarodowej polskiego eksportu na wybranym rynku. Badanie prowadzono na poziomie sektorowym. W studium wykorzystano metodę nazywaną wskaźnikiem atrakcyjności i pozycji rynkowej (wskaźnik AP). Technika ta odwołuje się do metod portfelowych. Umożliwiła ona kwantyfikację atrakcyjności rynku docelowego oraz pozycji konkurencyjnej polskiego eksportu na ten rynek. Badanie bazuje na danych EUROSTAT i obejmuje lata 2010-2018. Stosownie do wyników analizy wszystkie szeroko zdefiniowane klasy produktów oferowane przez polskich eksporterów na rynku niemieckim można uznać za konkurencyjne. Jako najbardziej perspektywiczne należy postrzegać klasy produktowe SITC 0+1, SITC 5, SITC 6+8 oraz SITC 7, charakteryzujące się ponadprzeciętnym tempem wzrostu rynku oraz wysoką dynamiką eksportu. Studium ma na celu jedynie ocenę konkurencyjności. Poszukiwanie czynników konkurencyjności nie jest przedmiotem badania.

Opis:

The aim of this study has been to determine the effect of a diet containing β-carotene and omega-3 fatty acids on the biochemical and nonspecific humoral immunity indicators and on the results of rearing calves to day 60 of life. The study was conducted in 2011-2012, on a herd of Polish Holstein-Friesian cows. 54 calves from the herd were divided into 3 groups, 18 animals in each: CTR, TRT1 and TRT2. During the colostral period lasting for 5 days after birth, calves were drinking the mother’s colostrum. From 6 to 60 days, calves were watered milk replacer formulation. The control group (CTR) consisted of calves after the colostral period given milk replacer formulation without any supplementation. In the two other groups, calves received milk replacers with the supplementation of b-carotene (TRT1 group) in the amount of 25 mg/calf/day or a suspension of liver omega-3 oil (TRT2 group) in the amount of 5g/calf/day. All calves received solid feed ad libitum. The research showed that the parameters of the metabolic profile of calves (ALT, ASP, CHOL, GLU, UREA, ALP, TG, CRE) were within the normal range, indicating good health of the calves. Moreover, the supplementation had a positive impact on the chosen immunological parameters, including a higher IgG concentration, especially at the end of the milk drinking period. The result of B-carotene in a diet was the highest daily gain in the period from 30 to 60 days of life among the analysed groups of calves. No such effect was achieved in the TRT2 group of calves, as their body weight was the lowest. However, noteworthy is the beneficial impact of beta-carotene and omega-3 oil on the non-specific humoral immunity parameters, which was manifested by fewer cases of clinical diarrhoea and upper respiratory tract diseases.

This article applies to searching for symptoms and diagnostic parameters pointing in a deterioration in the quality of the combustion process in marine diesel engines. It was assumed that diagnostic parameters should give clear information regardless of engine load or with respect to the mean indicated pressure. The proposed cycle and sectional net thermal (heat) efficiency characteristics and also dimensionless net heat release rate were analysed. In order to obtain the state of deterioration of the injection process simulation of discalibration (larger diameter) of injector holes was performed. The simulation was carried out by the enlarged of diameter of the injector holes form 0.375 mm to 0.385 mm. Deterioration of the formation and growth of fuel spray droplet diameter is result of such simulation. The study was conducted on a laboratory engine Sulzer Al25/30. The study was carried out according to active experiment plan, during which the selected engine failure of the injection system was simulated. Measurements of pressure of combustion were performed by means of tensometric sensors of Spice Company on the indicator valve. The analysis found that in the event of injector nozzle faults (discalibrated holes) significantly decreases the net thermal efficiency η c cycle, and there are significant oscillations of net

In this paper the basic assumptions of a Radio Signal Strength Indicator - based fingerprint and the influence of human body on the results are presented. The main focus is put on the influence of the obstruction of line-of-sight between access point and transceiver by a human body. This issue must be corrected in order to gain more accurate and reliable results of the positioning. The mathematical model for correction of this issue is proposed along with some examples. The examples are based on the real measurements made by authors. Presented correction formula allows to minimize the influence of the user - access point direction on the results obtained during fingerprint creation and positioning.

W pracy przedstawiono metodę pomiaru mocy indykowanej tłokowej sprężarki chłodniczej. Stanowisko zostało zbudowane w oparciu o agregat skraplający WF 180. Metodę badawczą oparto się na pomiarze ciśnienia w cylindrze sprężarki w funkcji kąta obrotu wału korbowego. Do pomiaru ciśnienia wykorzystano tensometryczny przetwornik ciśnienia własnej konstrukcji, natomiast do określenia położenia tłoka zastosowano układ kontaktron – wirujący magnes. Układ pomiarowy został zbudowany przy wykorzystaniu rejestratora MC201 oraz komputera PC. Pomiary pozwoliły określić parametry pracy badanej sprężarki oraz jej stan techniczny.
A method of indicated power measurement for a refrigerating piston compressor is presented in the paper. Based on a condensation unit of WF 180 an experimental set-up was built. The applied method was strictly connected with pressure measurements in a compressor cylinder as a function of crank rotation angle. These measurements were conducted using the extensometer pressure converter of authors’ own design. A piston position was determined by means of contactron – spinning magnet arrangement. MC201 recorder and PC were applied in the measurement system. The set-up enabled one to determine operational parameters for the compressor and assessment of its technical state.

Opis:

The aim of the article is verification of possibility of use of UNEP isolation indicator for measuring isolation of tropical islands for tourism purposes. 30 tropical islands were included in the study. The correlation between intensity of tourism movement and isolation indicator by Spearman rank correlation was -0,46. More isolated islands have smaller intensity of tourism movement and less isolated have higher intensity of tourism movement ratio. But there are also exceptions from this rule - territories which are more isolated and with higher intensity of tourism movement such as Maldives and less isolated with the smaller intensity of tourism movement such as Sao Tome and Principe. UNEP isolation indicator is not ideal measure for tourism purposes.

Opis:

Diamicton in Biesiekierz (central Poland), whose age and origin has long provoked debate, is located above unquestionable Eemian biogenic deposits documented by palynological and Cladocera analyses. Petrographically, this diamicton shows some similarities to Warthanian till. Lithologically, it shows considerable weathering of the deposit, a possible selection of the component minerals and addition of dispersed biogenic matter. The results obtained so far as well as the palaeomorphological situation indicate that the diamicton is reworked till material, as are sand intercalations within it. Given the organic content of this diamicton, we infer that a long-term agricultural exploitation of its immediate surroundings was the main factor behind colluvial reworking and displacement occurring above the Eemian biogenic deposits in the fossil depression.

Opis:

In this paper, we propose a new way to assess and compare the sustainability level of countries, using concepts and tools from the theory of partially ordered sets. Using so-called average height and the newer concept of embedded scales, we show how one can develop synthetic sustainability indicators, without aggregating attribute scores, through composite indicators. In particular, the paper shows how rankings of countries can be obtained out of multidimensional data systems, paving the way to more comprehensive sustainability studies, where the illustrated posetic methodology, and other tools from partial order theory, can be employed fruitfully. While setting the stage for the application of partial order theory, we also show the use of tools for dimensionality reduction, namely Non-negative Matrix Factorization, which to our knowledge is not yet so widely employed in environmental data analysis.

Opis:

In this paper, the authors present an introduction to the new method of evaluating the indicator diagram of internal combustion engine. For several years, it was observed that analyses of combustion processes have been hardly changed since they were conducted for the first time. At the moment, the diagrams are plotted more and more precisely owing to the new sensors and digital processors. Despite all of these high technical advantages, which were obviously unavailable in the past, theoretical approach for describing indicator diagram has not changed in significant way. Nowadays, the indicator diagrams are still evaluated very generally and are presented in much too idealistic way as a smooth curve of pressure changes, without any disturbances, which are being detected very easily now. Furthermore, it appears that performance improvements of the IC engines are in need of developing new methods for analysis and evaluation. The Fourier transform is a new way to look at the combustion process in the engines. It is basically a mathematical instrument for analysing different types of signals, which are transformed, from time domain into frequency domain. It enables identifying specific sinusoidal components of arbitrary signals and separates relevant ones from the noise. This allows one to see significant differences in two or more apparently similar signals and detect the crucial parts. If we treat pressure changes in time like a common signal, we can compute Fourier transform and see basic components of the diagram.

Opis:

The objective of the work was to describe the thermal and snow conditions in the winter period in the Siedlce area. The average daily air temperatures were used in addition to numbers of days with a snow cover of at least 1 cm for the years 2000–2016 obtained from the Meteorological Station in Siedlce. Dates of the beginning and end of the winter season were determined. The average temperature of the winter season was determined in addition to the degree of winter severity, according to Oskin. The average, minimum and maximum values of parameters were calculated. The probability of an occurrence of individual types of winter severity was determined. Next, principal component analysis and cluster analysis were applied, the latter to the group years in terms of the days with a given type of weather in winter. It was found that – on average – the thermal winter began on 5 December and ended on 6th March. The winter was found to have lasted for 66 days. From year to year, there was observed an increase in the average number of days with mild weather. The greatest decline was found for the days with the weather typical of slightly severe and moderately severe winter. The last study years had the highest average number of days with weather typical of mild, slightly severe and moderately severe winter, and the lowest number of the days with weather typical of severe, very severe, unusually severe and extremely severe winter.

Opis:

Land use and the landscape of the suburban area are strongly affected by the impact of a large city, which is an important factor determining their development. The paper presents the results of analyses of the functional and spatial transformations depending on the distance from city limits and main access roads. The analyses were based on CORINE data for the years: 1990, 2000 and 2006. The spatial transformations in the specified distance buffers were described with use of the indicator of the share of specific land use areas in the total surface area and the indicator of the average landscape patch surface area. The conducted analyses confirm that the spatial patterns characteristic for suburbanisation exist in the vicinity of large cities and along access roads. The phenomena noticed in the suburban zone of Wrocław include, among others, an increased share of surface area used for residential purposes, a decreased area of arable lands, and an increased concentration of commercial and industrial areas in the direct proximity of the city and access roads.

Opis:

Along with sea-level rise, one of the most detrimental effects of climate change, is salinity leakage, which significantly affects agricultural activities throughout most of the world. This occurrence is becoming increasingly dangerous. The purpose of this study was to use Geographical Information Systems (GIS) to assess the current situation of agricultural lands in the province of Al-Diwaniyah, by employing GIS to document the salt-affected sites and arrive at the most important criteria affecting those lands as well as build an application model for suitability to clarify the affected sites and come up with paper and digital maps. To accomplish this, the study relied on the available data by extrapolating and analyzing remote sensing images using salt equations to analyze the Landsat 8 satellite images, after which these data were subjected to spatial statistical treatment in ArcGIS software. Moreover, 20 samples were taken from ground sampling points and subjected to laboratory analysis to compare and document the results. The research resulted in the creation of an up-to-date database for the locations of salt ratio growth or decrease in the province of Al-Diwaniyah, which can be relied on, starting from and expanding in the future. Land maps, both paper and digital, have been created and can be used and inferred. The findings demonstrated the model’s ability to steadily discriminate among all salinity groups while maintaining consistency with the ground truth data. Each of the four major salinity categories was highlighted. The best-performing indicators were used to build the MLR model, which was then used to anticipate soil salinity. The salt levels may be determined by the MLR combining NDVI and SI-5 with a high correlation value (R2 = 75.29%). Finally, it is shown that by combining spectral indicators with field measurements, it is possible to chart and forecast soil salinity on a large scale.

The main objective of the paper was to visualize and analyze the relationships between selected economic and environmental indicators in the waste management system of Slovakia, i.e., the amount of fees for municipal waste in individual districts of Slovakia in 2019 and the amount of average monthly wage and unemployment in Slovakia in the same year. Data were visualized and analyzed on a thematic map and in a boxplot, and subsequently, they were subjected to statistical testing. Based on the performed analysis, we can confirm the statistical relationship between the average wage and the amount of fees for municipal waste collection and the statistical relation between the municipal waste fee and the unemployment rate in individual districts of Slovakia.
Głównym celem artykułu była wizualizacja oraz analiza zależności pomiędzy wybranymi wskaźnikami ekonomiczno-środowiskowymi systemu gospodarki odpadami na Słowacji, tj. pomiędzy wysokością opłaty za odpady komunalne w poszczególnych rejonach Słowacji a wysokością średniego miesięcznego wynagrodzenia oraz poziomem bezrobocia w 2019 roku. Dane zostały zwizualizowane przy użyciu mapy tematycznej oraz wykresu typu boxplot, następnie zostały poddane testom statystycznym. Na podstawie przeprowadzonej analizy potwierdzono statystyczną zależność pomiędzy średnim wynagrodzeniem a wysokością opłaty za wywóz odpadów komunalnych oraz statystyczną zależność pomiędzy opłatą za odpady komunalne a stopą bezrobocia w poszczególnych rejonach Słowacji.

The results of investigation of 1,9 TDI engine (285 Nm, 85 kW, type AJM without any modification) equipped with injection units supplied conventional diesel fuel (ON) or B100 fuel (RME) have been presented in article. Investigations have been realized at the engine speed of 2000 rpm and variable load within the range of 0 to 275 Nm. The pressure, temperature and heat release velocity runs have been subjected to analysis. Particular attention has been paid to the release of the heat used for the effective work and internal energy increase of the working medium (enthalpy) during combustion inside the engine cylinder versus the crank angle for both investigated fuels. It was found among the others that mentioned fuels differ in the heat release, heat velocity and the maximal combustion temperature, which for the B100 fuel is bigger than for the conventional diesel fuel. Bigger combustion dynamics of tested biofuel (compared with standard diesel fuel) results higher concentrations of Nitrogen Oxides NOx in exhaust gases. The easiest way is of course the use of the later start of fuel injection biofuels and/or increase the exhaust gas recirculation EGR. These treatments, however, result in a worsening of the energy performance of the engine. It was concluded also that the combustion of RME works properly at higher engine loads. Then reduce the negative difference between the combustion of biofuel (RME) and standard Diesel fuel.

Opis:

The article presents selected issues concerning the modelling of the supply chain in the evaluation of the efficiency of tasks realization. In the process of determination, efficiency of the functioning of the supply chain it is necessary to determine the components of both the effects and expenditures in quantitative terms. It is assumed that the effect resulting from action taken depends on the problem under consideration, for example, the result may be the amount of the profits, savings resulting from implemented solutions or measurable improvement of the quality system, expressed e.g. percentage. While the outlay incurred for the implementation of the action is, in general, the expense of implementing this action. The article pointed out that the assessment of the efficiency can be used to decide on the choice of a decision of the many variants of solutions to the problem. In this respect, important are indicators of the efficiency both the technical, economic, quality, and organizational. In the article were also presented possible approaches to improve the efficiency of the supply chain. In the problems of assessing efficiency of functioning of systems with a complex functional structure such as supply, chains increasingly are applicable algorithms based on the so-called heuristics. Hence, in the article briefly have been characterized also chosen heuristic algorithms – genetic algorithms.

The number of tourists has more than tripled, with an increase from 57% to 1830% in individual counties of Croatia during the analyzed period. At the same time, there was a disproportionately low increase in capacity of accommodation base across the country at the level of 76%. This increase took values from 20% to 350% in extreme districts.

Opis:

Monitoring of water ecosystems in Kazakhstan is based generally on chemical indicators. Biological indicators, such as macroinvertebrates and a phytoplankton are rarely used. Sometimes some macrophyte species of are used for the assessment of water quality. The aim of the study was to analyse the possibilities of the introduction of the Polish monitoring system based on aquatic plants for rivers in Kazakhstan watercourses. The Polish method uses the Macrophyte Index for Rivers (MIR) and it has been prepared for the purposes of the EU Water Framework Directive. The systematic structure of Kazakhstan’s water plants were analyzed and compared with the macrophyte list of Poland. Flora of Kazakhstan was used as the main source of information and some recent publications were analyzed as well. It was found that the aquatic flora of Kazakhstan is rich and a total of 240 taxa of emergent and submerged plants are identified in the country. We have confirmed that a large number of aquatic plants recorded in Kazakhstan are recognized as bioindicators. The ecological tolerance and sensitivity of the identified bioindicators was analysed. A preliminary nine taxa with the the highest indicator weight in the MIR system (W = 3) were detected as the most sensitive indicators in Kazakhstan flora: Sciuro-hypnum plumosum, Scapania sp., Ceratphyllum demersum, C. submersum, Potamogeton lucens, P. praelongus, Lemna gibba, Menyanthes trifoliata and Acorus calamus. It was found that the MIR index can be applied in Kazakhstan, especially if we enrich the list of indicative species with the local macrophytes, which were not included in the original version. The list of potential indicator-species includes: Ranunculus altaicus, Ranunculus natans, Althenia filiformis, Nelumbo nucifera, Trapa incise which does not occur in Europe and Nuphar pumila, Nymphoides peltata, Ranunculus rionii, Rorippa palustris, Trapa natans, Utricularia intermedia, U. minor, Eleocharis acicularis and Vallisneria spiralis.

The aim of the paper was to analyse the relation of milk yield per cow with a set of production factors on sample data from six dairy farms located in the central region of Poland. The farms, which were the subject of the study, carried out an intensive production, achieving milk yield over the national average. The research showed an increase in milk yield with increasing number of cows in the herd, which, in practice, can lead to increased loads in milking installations in farms keeping more cows.
Celem pracy była analiza powiązań między wydajnością mleczną krów a zbiorem czynników produkcyjnych na przykładzie danych pochodzących z sześciu gospodarstw mlecznych położonych w centralnej części Polski. Gospodarstwa będące przedmiotem badań prowadziły intensywną produkcję uzyskując wydajność mleczną powyżej średniej krajowej. Na podstawie badań wskazano na wzrost wydajności mlecznej wraz ze zwiększaniem liczby krów w stadzie, co w praktyce może wpływać na wzrost obciążeń instalacji udojowych w gospodarstwach z większą liczbą krów.

Opis:

Subject and purpose of work: The subject of the paper is entrepreneurship development and its determinants, with particular attention to the investment attractiveness of Polish provinces. The purpose of the paper is to identify the level of entrepreneurship development (between 2009 and 2017) and investment attractiveness (between 2009 and 2016) of individual provinces, and to define the correlation between the two features. Materials and methods: The authors of this paper analysed the literature on the subject and performed desk research using data from reports and studies published by GUS (Statistics Poland), PAPR (Polish Agency for Enterprise Development) and IBnGR (Gdańsk Institute for Market Economics). Results: In 2017, the number of SMEs* in Poland increased by over 24% in relation to 2009. The results showed a significant inversely proportional correlation between the number of enterprises per 1000 inhabitants and the one-year survival rate for the enterprises. The investment attractiveness of provinces was diverse. The level of investment attractiveness exerted a considerable influence on enterprise development in individual provinces. Conclusions: The results of the study showed that both the investment attractiveness and entrepreneurship are diverse in individual regions. A significant correlation was found between these two phenomena. Some exceptions to the rule were identified, which can be explained by divergence.

Opis:

The Tachypleus tridentatus (Chelicerata: Xiphosura) is an arthropod that usually displays high site fidelity by restricting its distribution to natal vicinities. Briefly, shore perturbation from boating (Kudat), electric, cyanide and bombing (Kunak) and tourism (Semporna) in Sabah can impair the T. tridentatus growth and produce sexually mature adults with unusual size. The 8-point morphometry of Tachypleus tridentatus from Kudat (Sulu Sea), Kunak and Semporna (Celebes Sea), produces the final output constituting accurate size classification for the species. Meanwhile, T. tridentatus are sexually dimorphic (p = 0.968–0.989), where male T. tridentatus (from Kudat) has prosoma width (27.75 ± 2.68 cm) and weight (1050 ± 610 g) in smaller ranges when compared to the female (33.27 ± 4.68 cm; 3020 ± 1480 g) using the same comparison. In addition, the T. tridentatus populations from Kunak (prosoma width: male = 28.91 ± 1.48 cm, female = 29.44 ± 5.47 cm; weight: male = 800 ± 275 g; female = 2550 ± 155 g) and Semporna (prosoma width: male = 21.73 ± 1.34 cm, female = 24.42 ± 1.36 cm; weight: male = 485 ± 306 g, female = 1320 ± 640 g) differed site-wise. The descriptive statistics (average and standard deviation) relate 7.1–23.0% of T. tridentatus with negative size class. However, the applied statistics using stepwise analysis and regression curve (r2 = 0.566–0.833), relates 30.4% of T. tridentatus with negative size class. Considering weight to produce 100% T. tridentatus with positive size class, it is biased because some crabs are gravid with eggs and if attained unpaired (male and female), they may have recently fed. Therefore, the prosoma (male), interorbit (female) and telson lengths are identified as most appropriate for the size classification of T. tridentatus. Thus, the findings provide a novel baseline for conservation studies that monitor symmetrical and unusual growth in the T. Tridentatus wild stocks.

Opis:

The seaside area is one of the most forested in the country. At the same time, the forests in the coastal zone are exposed to a strong anthropogenic pressure due to a high concentration of tourism development and tourism. The aim of the study was to analyze the changes in the forest area availability of the coastal tourist municipalities of the Baltic Sea Coast in connection with the changes in the area of tourism development and tourism in this area. The analysis was conducted in dynamic terms, taking into account the years 2000-2016. In this study, all the communes that directly border the Baltic Sea were taken into account as seaside communes. The statistical data of the Local Data Bank of the Central Statistical Office were used as the source material for the implementation of the research problem addressing: the changes in the area of total forests in all coastal communes of the Baltic Sea Coast in 2000-2016, the changes in the area and population of communes, and selected data on the tourist function of the coastal communes including the data on the number of facilities and beds as well as the number of tourists visiting the coastal communes of the Baltic Sea Coast between 2000-2016. In the coastal communes, in the years 2000-2016, the forest cover index increased from 23.3 to 24.1%. Since 2000, the forest area per 1 inhabitant increased from 1741 m² to 2149 m². The increase in the forest area and average forest area per capita occurred mainly in the rural communes, large communes with the highest forest cover indicators, in the urban communes while in the communes with a strongly developed tourism function, there was an opposite tendency. The increase in the tourism load on the forest areas and decrease in the availability of forests for tourists in the municipalities and communes with the largest tourist investment (Kołobrzeg, Międzyzdroje, Władysławowo) is observed. The anthropogenic pressure and the availability of forest decreases in communes with lower population and the marginal role of tourism in their socio-economic development (Choczewo, Trzebiatów, Smołdzino, Kamień Pomorski).

The article presents the usefulness of quantile regression for the analysis of diversification in entrepreneurship in rural areas of communes in Wielkopolskie Voivodeship. The dependence between the entrepreneurship indicator value and the density and availability of the water and sewerage infrastructure was determined for individual quantiles of the entrepreneurship indicator distribution. This approach enables estimation of different quantile functions of the conditional cumulative distribution function of the entrepreneurship indicator. This analysis enables atypical observations when the conditional cumulative distribution function is diversified and does not have a standard form.

There is no doubt about the importance and impact of ports on our environment. The search for a mute smart, supported among other elements in the smart industry, makes ports look smart. The penetration of the concept in the Spanish port model makes it necessary to establish some indicators and some measurement indexes that allow categorizing the different ports according to their smart port component. It is concluded from the study that the ports of Valencia and Barcelona, predominantly container ports, are the ports that have a higher degree of smart ports.

Opis:

Petrographic analysis, including the indicator erratics count method of coarse pebbles (20–60 mm), was performed for the first subsurface layer of the glacial till in the vicinity of the city of Radom. Crystalline rocks comprise 60% of the sample, whereas carbonate and clastic sedimentary rocks total 18% and 15%, respectively. Among the crystalline rocks, 14% clasts were identified as indicator erratics. The majority of the indictor erratics originated from the Åland region (63%). Significant contributions were also derived from the central Baltic Basin (12%), Ångermanland (9%) and Uppland (9%) regions. Trace amounts are recorded from the northern Baltic, Dalarna and Småland regions. The spatial distribution of crystalline erratic source areas suggests material incorporation into an ice sheet mainly from central-eastern Fennoscandia. The indicator assemblage composition indicates the Odranian (MIS 6) origin of the till. The majority of the erratic sedimentary rocks were derived from the central and southern Baltic Basin while local rocks comprise a minor proportion. The relatively low carbonate clasts content indicates that the till was affected by partial decalcification resulting from post-depositional chemical weathering. This study supplements the results on erratic pebble provenance in the glacial tills of Middle Polish Glaciation Complex in Poland.

There have been showed on limitations occurrence at measurements fast-changed pressures of marine diesel engines in operating conditions and measuring errors the attendants. Mean indicated pressure determined from the indicated timing or angular pressure courses in the cylinders is still a reliable diagnostic symptom. The paper presents too the results of experimental measurement of in-cylinder pressure signals, medium speed marine engines with application resistive sensor and using the photo-optical sensor of crankshaft position, and without the marker position of the crankshaft. Not always possible to altach the marker for the position of the crankshaft, and even there is no way of stopping the engine when you need to diagnose it. The top dead centre of the piston can be determined then analytically. The work developed a method of determining the mean indicated pressure of the developed indicator diagrams. Based on calculations ofmean indicator pressure made many of diagnosis of the medium speed marine diesel engines in the operating conditions.

Opis:

The topic of this article is to analyze the influence of indicator diagrams smoothing methods on diagnostic parameters determined on their basis such as the maximum combustion pressure, mean indication pressure and heat release characteristics. Indicator diagrams of marine engines are subject to serious distortions arising primarily from the measuring method for in-cylinder pressure. Measurements are performed on the indicator valve which connect with the combustion chamber through the indicator channel. Depending on the engine design the channel length can reach a considerable length and introduces significant distortion in both the phase and amplitude of the pressure signal. Further analysis of the indicator diagram eg. in order to determine the heat release characteristics requires the use of methods of smoothing and filtering of interference. The results confirm no effect of indicator diagram smoothing for the value of the mean indicated pressure, which is one for the most important indicated parameters. A significant influence of smoothing on the maximum value of the heat release rate was observed. The differences in this case exceed 50%. At the same time confirmed that the heat release rate curve determined on the basis of a diagram without smoothing, carry a high level of interference, which precludes their practical use. Smoothing allows getting heat release rate curves that carry vital information about the working process of the engine.

Opis:

Poland was the only economy among the European Union members, which avoided the recession of 2007-09. Nevertheless, the impact of global recession was visible in many areas of the Polish economy. The paper analyzes some of the main reasons behind this outstanding performance. The analysis is based on data from business surveys, composite coincident and leading indexes and official statistics on Poland’s economy. The reasons are divided into four groups: (1) General economic condition before the global crisis. In this part the large inflow of direct investments and fast growing productivity throughout 2004-2007 are emphasized. (2) Structural factors related to the stage of Poland’s economic development. The main factors in this group are: low dependence on business and consumer credit; absence of high risk financial instruments (securities based on US subprime mortgages) in the banking sector; relatively small external ties of the Polish economy with relatively big domestic market. (3) Benefits of the EU membership. Poland benefited from the large share of investments linked to EU transfers since May 2004. It boosted the activity in sectors such as building and construction and reduced the scale of layoffs. (4) Market forces. Despite Poland’s goal to join the euro area as soon as possible, its own currency and floating exchange rates helped to enhance Polish export during recession. Strong Polish currency during the period of high oil prices (2007-2008) prevented the economy from increasing costs of production and made imports cheaper. The later depreciation of the zloty (2008-2009) made export goods more competitive on the international markets which prevented Polish exports from declining. Another factor in this group is the absence of any special stimulus programs undertaken by the government.

The basic elements determining the cooperation of reinforcement inserts with the ground centre are discussed, depending on the features characterizing the components of the composite. The method and selected results of tests performed on a massif model with a vertical wall made of non-cohesive ground have been presented. A calculation example is given concerning the internal dimensioning of the reinforcement of the considered massif model, assuming the work of inserts without slipping in the ground centre. The concept of reinforcement co-operation indicator with the ground centre was introduced and a dependence to calculate its value was developed. The values of co-operation indicators: general and partial, concerning individual measurement levels of the model have been presented appropriately.

Opis:

Product customization and dynamically changing customer requirements cause multiple versions of the same product to be created with minute modifications, e.g.: different colour, material used, accessories, etc. Adapting to changing tendencies determines the manufacturer`s competitiveness. This article presents the analysis of the flexibility of a complex convergent production structure. The analysis has been conducted using the EPE (Every Part Every…) indicator. To maintain the accuracy of the system`s evaluation, the flexibility determining algorithm has been adjusted to the analyzed cell structure. A flexibility indicator EPE shows the lowest possible frequency at which the rotating production of a batch is repeated. In practice, it informs us after what time we may manufacture the same lot of goods again, taking into account the time necessary for delivering accepted orders. The conclusions from the conducted analyses helped to develop strategic development plans which assumed increasing the volume of the manufactured assortment both in number and variety.

The article proposes the construction of a synthetic indicator which allows the classification of regions according to the achieved level of environmental governance based on the data available in the database BDL GUS. The comparison of results of own calculations and data from the OECD allows to assess, if the inference based on only one variable, as is in the case of OECD report, is consistent with the assessment of environment based on all available in BDL variables. Both approaches lead to very similar conclusions.

Opis:

The aim of the studies was determining the spatial distribution of premises and the technical means of production resources on farms in the years 1996, 2002 and 2010. The database has been developed for 36 counties of the Śląskie voivodship. The spatial database developed for the analysed voivodships assumed a county as the smallest indivisible unit of the geographical space. The data describing the technical means of production on farms were obtained from inquiries conducted by the European Statistical Office. Diagnostic variables describing the technical equipment on farms included: self-propelled machinery, tractors and usable areas. The analysis of spatial distribution was conducted for the assumed period of time and spatial changes were determined. On the basis of the analysed diagnostic variables the synthetic indicator was determined, which described the multivariate phenomenon by means of one variable. The analysis show that in 1996 agricultural farms were better equipped on the level of the measure of development 0.306 than in 2002, when the measure of development was lower by 0.100.

Opis:

Rising food prices mean that solutions are sought that will reduce the costs of agricultural production. One area of research is precision agriculture. This solution requires a computerized plant growth monitoring system. The paper presents a computer system for monitoring plant growth, developed for the needs of precision agriculture for small agricultural areas. The work contains a description of the monitoring system divided into the key elements of the process. An exemplary method of preparing orthophotomaps of the area was presented. The method of making maps that can be implemented on a personal computer has been described. The paper describes the most frequently used Geologic Indicators and Vegetation Index. A test of determining the coefficients was carried out on exemplary acreage with an area of 5.28 ha. Typical positioning systems for agricultural machines are discussed. The DGPS (Differential Global Positioning System) navigation method was used in the tests, which confirmed that it can be used in precision agriculture for small agricultural areas while maintaining sufficient positioning accuracy. The presented system was tested during one cycle of vegetation of winter barley sown with the no-plowing method. On this basis, an analysis of savings resulting from the reduction of the amount of fertilizers and plant care products used was carried out. The proposed system does not require complicated computer systems. It was designed in such a way that it can be implemented on standard PC equipment cooperating with a short-range drone equipped with a standard RGB (Red Green Blue) camera.

Opis:

The aim of the research was to identify the influence of environmental factors inherent in the alluvial and displaced sands of the study region on the growth of the Jack pine and the prospects for its cultivation. We found that the success of growth of Jack pine seedlings on sandy soils depends on a set of factors, which include the presence or absence, in the rhizosphere of sand, of humus impurities and genetic horizons of zonal soils, silty or loamy layers, soil density and composition of pine stands formed in the cultivation. On alluvial sands, sparse forests of Jack pine and Scots pine with a density of 0.3 units were formed. The yield of seeds from Jack pine cones was 1–2% higher than the normative values, and the mass of 1000 seeds was 50% higher. Jack pine seedlings grow according to I class of productivity on displaced sands, with an admixture of humus mass and remnants of genetic horizons of zonal soils at the root depth. In the rhizosphere of the stand, the roots of Jack pine seedlings occupied 78% of the mass of all roots that inhabited a metre-thick sand. Jack pine seedlings that fall under the canopy of Scots pine fall out of the plantations due to drying, which indicates their demand for light and appropriateness of growing Jack pine in solitary plantings or in mixed low-density plantations with Scots pine.

Opis:

In this paper the issue of globalisation and deteriorating precision of domestically oriented frameworks is addressed. A hypothesis that the effect of international trends on the growth of economy is increasing over time is formed. In order to validate this, a method of composing foreign series with local indicators in a hierarchical dynamic factor model is presented. The novelty of this approach is that globalisation effect is measured focusing on prediction rather than similarity. This way the measure presents the country's sensitivity to global shocks and reveals how much focal country's economy is intertwined with global economy. The application was performed on the basis of Lithuanian data and the hypothesis was validated. The results indicate that globalisation effect has an increasing effect over time.

Opis:

Ocena zachowania się górotworu wokół wyrobisk i skuteczności ich wzmacniania w podziemnych kopalniach rud jest uzależniona od efektywności współpracy obudowy kotwowej z górotworem, którą można oceniać na podstawie odpowiednio zaprojektowanych pomiarów. Na tle opisanych w literaturze kilku rozwiązań dotyczących sposobów monitorowania obciążenia obudów kotwowych autorzy zaproponowali nowe, oryginalne urządzenie umożliwiające masowe pomiary w warunkach kopalnianych. Po przeanalizowaniu zalet i wad istniejących konstrukcji w artykule przedstawiono istotę, zasadę działania oraz metodę pomiaru obciążenia kotwy w wyrobisku podziemnym za pomocą nowego przyrządu. Wykonany prototyp WK-2/8 został wycechowany oraz przetestowany z powodzeniem w warunkach laboratoryjnych w pełnym zakresie pomiarowym. Przyrząd ten, nazwany również wskaźnikiem lub podkładką dynamometryczną, nie wymaga zasilania elektrycznego i umożliwia, stosunkowo precyzyjne (z rozdzielczością 10–14 kN, w zakresie do około 90 kN) i zdalne odczytanie wartości siły osiowej obciążającej kotew (patent AGH) przez każdą osobę znajdującą się w określonym rejonie. Przyrząd może być instalowany w wyrobiskach górniczych w warunkach istniejących obciążeń. Stosunkowo niski koszt wykonania przyrządu pomiarowego, stanowiącego dodatkową podkładkę, jak również łatwy sposób montażu, umożliwiają jego powszechne zastosowanie w kopalniach, gdzie stosuje się kotwienie jako sposób wzmacniania górotworu.
The assessment of a rock’s behaviour around excavations and the effectiveness of its reinforcement in underground ore mines is dependent on the performance of the rock-bolt and rock-mass interaction, which can be estimated on the basis of appropriately designed measurements. Based on the background of various measurements solutions described in the literature, concerning rock bolt monitoring methods, the authors proposed a new, original device for mass measurements in mine conditions. After examining the advantages and disadvantages of existing constructions, the article presents the essence, principle of operation and method of measuring anchor load in an underground excavation with the a instrument, indicator WK-2/8. The prototype has been carefully researched and successfully tested in a full-scale laboratory environment. This instrument, also referred to as a load indicator or force pad, does not require electrical power and allows for relatively accurate (with a resolution of 10-14kN, up to about 90kN loading capacity) and a remote reading of the axle loading of the anchor (AGH patent) by any person present in the specified area. The device can be installed in mining excavations under loading conditions. The relatively low cost of a measuring instrument, practically used as an additional washer, as well as an easy assembly method, makes it universally applicable in mines where anchoring is used as a means of strengthening the rock.

Celem badań była analiza zanieczyszczenia gleby w rejonie zakładów metalurgicznych w dzielnicy Opole-Metalchem. Jako wskaźnika użyto Pb-210, ponieważ podwyższona jego aktywność może wskazywać na obecność innych zanieczyszczeń na badanym terenie. Na podstawie uzyskanych wyników obliczono aktywność ołowiu nadmiarowego. Największe jego aktywności zaobserwowano w glebie na terenie leśnym. W miejscach z podwyższoną aktywnością ołowiu nadmiarowego odnotowano także wyższe wartości aktywności Cs-137.
The aim of the study was the analysis of soil contamination in the area in vicinity of metalworking plants located in the district Opole-Metalchem (PL). Pb-210 was used as pollution indicator because its increased concentration of activity may indicate the presence of other contaminants in the studied area. On the base of the obtained results, the activity concentration of the excessive lead was calculated. Its biggest value was observed in soil in a forest area. In areas with increased excessive lead content also elevated values of Cs-137 activity concentrations were recorded. Atmospheric source of Pbex and Cs-137 deposition was supposed.

The paper presents the results of research of the influence of clogged injector nozzles in fuel injection system on the shape of heat release characteristics. The study was conducted on a laboratory four-stroke marine engine, type Sulzer 3Al 25/30, with nominal power Ne = 408 kW at nominal rotational speed n = 750 rpm. The study was carried out according to active experiment plan, during which the engine failure of the injection system was simulated. Simulation of loss of patency of injector nozzles (clogged) was to completely clog two holes of nine injection injector nozzle holes with a diameter of 0,325 mm. Measurements were made at a constant engine speed of 750 rev/min for five loads: 50, 100, 150, 200, 250 kW. Measurements of pressure of combustion were performed by means of tensometric sensors of Spice Company. Based on measured pressure curves heat release characteristics were determined. The algorithm allows the determination of net heat release rate q and the net generated heat Q characteristics. Based on the obtained results it can be concluded that significant improvement in the diagnostic use of indicator diagrams can be obtained by using heat release characteristics. These characteristics are correlated with the process of fuel injection and the injection pump operation. As demonstrated in the work of analysing the heat release rate q, it is possible to infer diagnosis on the technical condition of the fuel injection system.

The paper aims to present the results of investigations into the engine with Common Rail system that performs multi-phase injection. The scope of investigations included measurements and assessment of fast-changing quantities. The paper provides the research stand description and a block diagram o f the system for taking measurements offast-changing quantities, including the system measuring the intensity of the current that controls the injector operation. The experimental results discussed in the paper were derived from introductory investigations into measurements of the air-fuel mixture pressure in the engine cylinder and those of the injector needle lift, which were assessed on the basis of measurements of the intensity of the injector-controlling current. Tests were performed while the engine operated under external speed characteristics and under load characteristics at the crankshaft rotational speed n=l200 rpm and n =3800 rpm. During tests, depending on speed and load characteristics of the engine operation, the ECU performed different strategies of fuel injection. The fuel injection control system madę it possible to complete three injection stages in a single work cycle of the internal combustion engine (pilot injection, pre-injection and the main injection). The maximum fuel pressure in the common rail amounted to 160 MPa. The engine was fuelled by commercial diesel oil.

Opis:

In the polytropic model of compression process, exponent of polytropic compression curve was replaced with a power polynomial in which the piston travel was used as its argument. It was shown that 3rd order polynomial is optimum one. In the model were taken into account the following: design parameters of cylinder, influence of cylinder wear and gas blow-by on compression process, error in determining the piston’s Top Dead Centre (TDC) location, measurement error due to indicator diagram’s truncation. The presented solution of the non-linear model is based on its partial linearization, use of the least squares method as well as on application of the optimum determination methods known in the theory of experiment. The model makes it possible to determine TDC location on indicator diagram dealing with combustion, determination of total compresion ratio, pressure value of indicator diagram truncation, as well as determination of maximum values of compression pressure on the diagrams in which self-ignition occurs before reaching the TDC.

Opis:

The article's primary goal is to demonstrate the problems inherited in 'operationism - antioperationism' polemics. The opinions on operationism are divided. The term 'operationistic views' is a conceptual cluster, in which the components' meanings are imprecise. The term 'operational definition' shares the same quality. In general science methodology many distinguished social science methodologists continue developing and modifying operationism. Both the supporters and critics of operationism have succeeded in formulating a significant number of prominent methodological issues; operationism studies inspire thinking on the methods of concepts, indicators and techniques selection in science as well as on the reasoning for the choices made. I suggest to call the extension of operativeness postulate the operativity postulate. It reads: concepts are to be defined through descriptions of observable states of matter. Definition's operativity postulate shall be applied to definitions of indicated properties (in cases of definitional indicator) as well as to definitions of indicators (in case of correlation indicator).

Opis:

Background: Key Performance Indicators are a common way of quantitative monitoring of project progress in modern companies. Although they are widely used in practice, there is little evidence on how they are set, and how many of them are used in large product development projects. Goal: The goal of this paper is to explore how KPIs are used in practice in a large company. In particular, it is explored whether KPIs are used continuously or only during short, predefined periods of time. It is also explored whether software-related KPIs are reported differently from non-software-related KPIs. Method: A case study of 12 projects at the Volvo Car Group in Sweden was conducted. The data from the project progress reporting on tools was collected and triangulated with data from interviews conducted with experts from the company. Results: KPIs are reported mostly before the milestones and the manual assessment of their status is equally important as the automated data provision in the KPI reporting system. The trend of reporting software-related KPIs is very similar to the non-software-related KPIs. Conclusions: Despite the documented good practices of using KPIs for project monitoring, it is difficult to develop a clear status-picture solely using quantitative data from progress reporting tools. It was also shown that the trends in reporting the software-related KPIs are similar to the trends in reporting the non-software related KPIs.

Opis:

Carrot is a vegetable of great importance to our country. Poland is a major carrot producer in Europe. Therefore, carrot turnover, and especially quality control and its utilization, are of great importance. So far, there has been only one division of carrot into three quality categories, accepted within the European Union. The method of assessment is time-consuming and subjective. There is no method, however, which would be quick in realization and objective. Below, we proposed a quantitative carrot assessment method in the form of quality indicator and studied interdependency between carrot quality and measurable carrot colour discriminant. The indicator allows taking into consideration factors, which are decisive as regards carrot utilization.

Opis:

Soya meal is the main high protein source in feeding pigs and poultry. Taking into account the annual value of domestic import, limited soya seed producers (USA, Argentina, Brasil) and China as the main soya seed importer (66 percent of the world import), a use of alternative protein sources (grain legumes, rape meal, DDGS) seems to be justified. An additional reason for a so called protein security in Poland are the feed regulations prohibiting a usage of GM products in feeding. Polish Government launched research projects for two periods (2011–2015 and 2016–2020) to solve main problems related to increased production and usage of domestic protein sources in animals feeding. Main strategies and research results of four areas – grain legume genetics and breeding, cropping technologies, pigs and poultry feeding and economic aspects of production, market infrastructure and turnover of domestic protein crops – are presented in the paper. Satisfactory is an increase of acreage under grain legumes in Poland – from 100 thousand ha in 2011 to 300 thousand ha in 2019. At present, given the availability of domestic grain legumes and rape meal it is possible to decrease soya meal imports up to 60–50 percent. Over the past decade, a strong increase of poultry meat production (about 120 percent) with a rather small increase of soya meal imports (about 18 percent) is also as optimistic tendency. A lasting solution may be achieved by setting a national/ European indicator target that would put the mandatory share of domestic protein sources in feed mixes at 10–20%, and creation of Polish feed companies, competitive to foreign, both large and mobile feed mixing plants, using the farmer’s raw materials.

Opis:

In this study, the data from the Programme for International Student Assessment (PISA) are used to investigate whether the PISA science test score is a good indicator of competence in science and technology. The researcher uses a number of scientific and technical journal articles per million people as a measure instrument to represent the competence of science and technology. A regression model analysis suggests that the PISA science scores would significantly predict competence in S & T, even when controlling the number of researchers in R&D per million people and the R&D expenditure (% of GDP). Moreover, it shows that R&D expenditure (% of GDP) is another important determinant of the competence in S & T. Multicollinearity is also found between the R&D expenditure (% of GDP) and the number of researchers in R&D per million people. The policy implication is clear.

Opis:

The paper presents a method of obtaining short-term positioning accuracy based on micro electro-mechanical system (MEMS) sensors and analysis of the results. A high-accuracy and fast-positioning algorithm must be included due to the high risk of accidents in cities in the future, especially when autonomous objects are taken into account. High-level positioning systems should consider a number of sub-systems such as global positioning system (GPS), CCTV – video analysis, a system based on analysis of signal strength of access points (AP), etc. Short-term positioning means that there are other locating systems with a sufficiently high degree of accuracy based on, e.g. a video camera, but the located object can disappear when it is hidden by other objects, e.g. people, things, shelves etc. In such a case, MEMS sensors can be employed as a positioning system. The paper examines typical movement profiles of a radio-controlled (RC) model and fundamental filtering methods in respect of position accuracy. The authors evaluate the complexity and delay of the filter and the accuracy of the positioning in respect of the current speed and phase of movement (positive acceleration, constant) of the object. It is necessary to know whether and how the length of the filter changes the position accuracy. It has been shown that the use of fundamental filters, which provide solutions in a short time, enables to locate objects with a small error in a limited time.

Opis:

In order to determine indicator diagrams-based heat release characteristics, a single- zone model of net heat release was used for perfect gas. It was proved that when a constant value for isentropic exponent is assumed, the error in determining the characteristics can be limited to 1% at the nominal load. The effect of errors in determining the position of piston TDC, as well as that of gas passages and indicator valves on the calculated characteristics was evaluated. It was shown that for low-speed engines the effect of gas passages in negligible, while for medium-speed engines the characteristics reveal some deformations (waves), which are repeatable for an individual cylinder in the examined engine construction. The results of the performed investigations and analyses suggest possibility and advisability of the use of heat release characteristics in diagnosing ship engines, in particular low-speed machines.

The main cause of social exclusion is poverty, but the authors say thatpoverty is not synonimous with social exclusion. The authors assume that poverty is anessential dimension of social exclusion – perhaps the most important one , which apart fromthe remaining (selected) objective factors, will consist of characteristics social exclusion inPoland,with particular emphasis on the situation in kujawsko-pomorskie voivodship. An article in the theoretical section attempts to sort out the discussion on the issue of social exclusion, the relationship between poverty and social exclusion. Moreover focuses on the measurablefactors illustrating this issue and its spatial differentiation.At the very beginning to the analysis of spatial diversity of social exclusion was the review and selection of diagnostic variables characterizing this problem. Then using linearalignment method, referred as Perkal’s synthetic indicator, was made the classification ofsurveyed voivodships (from the point of view of the obtained indicators of the level of ofthreat to its inhabitants by social exclusion). In addition, as a supplement to Perkal’s syntheticindicato,was used Ward’s agglomeration method.The main part of the article focuses on the subjective analysis of selected factorsconducive to social exclusion. The study assumes that social exclusion is not the same aseconomic scarcity, that’s why were taking into account indicators that cover a wide range ofsocio-economic phenomena, also affecting non-economic aspects of life, including: registeredunemployed persons unemployed for more than 1 year in the total number of unemployedpersons; at risk of relative poverty line; at risk of “legal” poverty rate; at risk of extremepoverty rate; average monthly per capita disposable income in the household; numer ofpersons in families benefiting from social assistance due to poverty per 1000 inhabitants;percentage of dwellings equipped with bathroom; indicator of the test result in lowersecondaryschoolin mathematics and natural science; percentage of children covered by pre-school education.At the end examined subjects were sorted according to the value of Perkal’s index andthe classification of the voivodships was performed. Again particular attention at this stage ofthe analysis was put on the situation of kujawsko-pomorskie voivodship

Ecotourism is widely accepted as the most effective type of sustainable development. For monitoring ecotourism sustainability in the Northern forest of Iran, a study was designed to help identifying criteria and indicators (C&I) with the principle goal to ensure the objectives of forest management, and at the same time – maintain processes in a sustainable manner. Indicators act as an instrument which can be used for monitoring sustainability. Hence indicators should be multidisciplinary, and cover all aspect of social, ecological, cultural, economic and institutional factors affecting sustainability of ecotourism. In this study, C&I were identified by using the Delphi approach through multidisciplinary panel team. Three rounds of meetings were held for discussions and dissemination of research to a panel of local experts. At the end of the second round we reached a consensus on 9 criteria and 61 indicators, which include 21 indicators related to ecological aspects, 8 to economic aspects, 21 to social aspects, 6 to cultural aspects and 5 to institutional aspects. The selected indicators would be applied by the Iranian Cultural, Heritage, Handicrafts and Tourism Organization for monitoring ecotourism sustainability in the Northern forest of Iran.

Opis:

Open pit coal mining is a global problem, because mines occupy large areas that completely change the relief, dramatically affect ecosystems, as a result of which they lose most of their functions, and a significant part of the fertile soil degrades and becomes unsuitable for agricultural activities. In the presented work, the initial stage of soil formation was studied, the parameters of the granulometric composition of uneven-aged rocks of Donbas mine dumps, their nutritional regime, and the species composition of soil algae were studied. Samples were taken from three different-aged rock dumps of the mines: "South-Donbaska - 3" (rock storage for 40 years); "South-Donbaska - 1" (storage of rock for 52 years), "Trudovska No5 - bis (storage of rock for more than 100 years). The agrochemical parameters of the rock were determined in the samples: pHwater, humus, nitrate nitrogen, mobile phosphorus, exchangeable potassium, particle size distribution. The determination of granulometric fractions of 0–20 cm layer of rock dumps of the mines shows, along with the age, a potential increase of the dump of fine fractions and a decrease in the fraction of stones from 83% in the dump of the South-Donbaska mine, and by 30 to 64.7% in the dump of the Trudovska No. 5-bis. The proportion of the clay fraction is not high in all dumps and it does not exceed 1%, but its appearance indicates the initial stage of a soil structure formation. Soil formation begins with the colonization of mineral rocks with soil algae. The species composition of soil algae, the quantitative accounting were determined by microscopy of a freshly selected soil sample and by cultural methods. Algae species were determined by determinants. In the rock dump, the structure of algal groups becomes more similar to, their structure in the background soils of the territory. The dominance of the representatives of Chlorophyta and Cyanophyta in the rock indicates the steppe process of soil formation. The data obtained contribute to the expansion of the ecological and biological understanding of the initial stages of the formation of soil cenoses.

Changes in the floristic composition of meadows and pastures may provide information on the human impact on the habitat conditions and intensity of land use. The aim of the study was to present the floristic diversity of the Lolio-Cynosuretum association and its relation with the habitat conditions evaluated using the phytoindication method with Ellenberg indicators. The study was conducted in five river valleys in the years 1999-2012. For the analysis, 100 relevés were selected, which were subject to floristic, habitat (phytoindication), and statistical analysis. In the Lolio-Cynosuretum phytocoenoses, the total number of 178 taxa of vascular plants from 33 families was recorded. It was demonstrated that the differentiation in the floristic composition of Lolio- -Cynosuretum phytocoenoses remains in relation with the habitat conditions, which may be evaluated basing on the ecological preferences of plant species that form the taxa. The species were established as differential for the lower units, that is four subassociations and eight variants.

Celem pracy było przedstawienie zróżnicowania florystycznego zespołu Lolio-Cynosuretum oraz jego powiązanie z warunkami siedliskowymi ocenionymi metodą fitoindykacji z zastosowaniem wskaźników Ellenberga i in. Badania prowadzono w pięciu dolinach rzecznych w latach 1999-2012. Do analizy wybrano zbiór 100 zdjęć fitosocjologicznych, które poddano analizie pod względem składu florystycznego, wymagań ekologicznych gatunków oraz statystycznym. W fitocenozach Lolio-Cynosuretum zanotowano łącznie 178 taksonów roślin naczyniowych z 33 rodzin. Wykazano, że zróżnicowanie składu florystycznego fitocenoz zespołu Lolio-Cynosuretum pozostaje w związku z warunkami siedliskowymi, które można ocenić na podstawie preferencji ekologicznych budujących je gatunków roślin. Gatunki te uznano jako wyróżniające dla niższych jednostek, tj. 4 podzespołów i 8 wariantów.

Opis:

The paper presents the results of research on the impact of currency regime type on features of the spread of financial crises. The focus is on constructing a neural network to identify groups of countries exhibiting similar behaviour in the dynamics of the index of flexibility in the effective exchange rate, exchange market pressure and external public debt markets in times of sudden changes in the environment. The alpha-criterion for optimality constructed in this way is based on the use of a concordance coefficient. The result of modelling is a self-organization map with a hidden layer consisting of six clusters. This cluster structure allows us to analyse the relationship between the type of currency regime and the consequences of the global crisis in 2007–2009 for the domestic financial markets of the investigated countries. It is found that the result of the division is significantly influenced by the proximity of administrative boundaries and historically predetermined close trade and economic channels of interaction between economies. The results obtained can be used to formulate directions in the currency policies of developing countries, including Ukraine.

Opis:

W artykule dokonano przeglądu prac, w których wykorzystano mierniki taksonomiczne do oceny zagrożenia przestępczością. Zwrócono uwagę na pewne dyskusyjne kwestie, jak np. dobór i redukcja zmiennych, będących składowymi konstruowanego miernika. Artykuł kończą rekomendacje rozwiązań w zakresie opracowywania taksonomicznych mierników oceny zagrożenia przestępczością oraz identyfikacji grup obszarów podobnych pod względem wybranych charakterystyk.
There were reviewed the papers which propose the use of taxonomic measures to assess the crime rate. Some debatable issues were noted, such as the selection and reduction of diagnostic variables that are components of the constructed taxonomic measure. There were recommended solutions for constructing taxonomic measures for assessing the crime rate and the identification of groups of areas similar in terms of selected characteristics.

Opis:

The intensive development of industry generates a number of negative consequences, which leads to an ecological crisis. As a result, the soil on which plant products are grown is polluted by radionuclides, heavy metals, pesticides, and chemicals. That is why in the early 1960s, the alternative farming, which is also called biological, biodynamic or organic, began to develop in Europe. The movement for alternative farming is widely developing in industrialized countries with a high level of chemization of agriculture. Therefore, the proposed topic is extremely relevant in terms of rational nature use, ensuring the sustainable development of territories, as well as food security in Ukraine. The article deals with agroecological assessment of suitability of agricultural land of the Steppe Zone of Ukraine for ecological farming and bases on the modern data from the Kherson branch of the state institution “Institute of Soil Protection of Ukraine”. Spatial modeling of the presence of nutrients in the steppe soil of Ukraine was made by the means of ArcGIS 10.1 product. Taking into account the obtained data and spatial modeling, the territories with soils of limited suitability for ecological farming occupy 67.2% (1194.5 thousand hectares) of the Kherson region, unsuitable soils are located on 16.7% (297.4 thousand hectares) of agricultural land of the Steppe Zone of Ukraine and suitable lands were detected on 16.1% (286.2 thousand hectares) of the territory of the studied lands. The conclusion was made that with the actual availability of lands occupied under ecological farming (4.3% or 75.9 thousand hectares), the territory of the Steppe Zone of Ukraine has a prime potential to increase the area under ecological farming by 4.2 times. Therefore, the article paid attention to ecological farming, taking into account the specifics of the content of trace elements in the steppe soils and their compliance with the methodology for determining whether soils belong to the categories of suitable, limited-suitability and unsuitable for ecological farming.

Opis:

Presence of plant species, associated with ancient forests (continuous existence >200 years) can be used for assessing woodland biodiversity. The aim of this study is to specify which plant species, included in the ancient forests plant species list, can indicate old woodlands in parks and what plant features are characteristic for certain habitat types. Richest in ancient forest plant species are those fragments of woodlands, which have existed continuously for at least 120 years, and their fragments suffered least from human pressure during that time, whereas recent woodlands are characterized by a small share of ancient forest indicator species and domination of nitrophilous species. Investigated plants usually propagate vegetatively, their seeds are of a small size and they have regularly, densely set leaves. Plants associated with ancient woodlands are good indicators of woodland continuity in parks so they can be used for age assessment in these areas. Accumulation of such plants can be a useful criterion in parks evaluation. Proposed idea of sustainable management of a park space, including selection of areas of a great ecological value, can be a chance to preserve woodland biodiversity.

Opis:

The sewage treatment plant, as a producer of renewable energy, should make every effort to ensure that the biogas used as a fuel meets the quality requirements, including those of the manufacturers of cogeneration units. Such measures necessitate the application of a conditioning process of biogas in order to remove harmful compounds, so that its parameters ensure failure-free operation of engines. The aim of the research was to evaluate the effectiveness of biogas treatment in the A-type installation using the “wet biogas treatment” technology, and in the B-type installation, which is a comprehensive solution comprising sulfur removal as a result of a simultaneous regeneration of the bed with oxygen, removal of siloxanes on activated carbon, cooling and heating of biogas along with its filtration. The analysis of the results of biogas testing for these two installations demonstrated fundamental qualitative differences for the benefit of the installation B, in which the biogas was characterized by a much lower content, mainly of sulfur, hydrogen sulfide, siloxanes and humidity. The introduced pollution indicator of a megawatt hour produced in cogeneration one has confirmed much higher pollution load from the A-type installation. The hybrid solution applied in the work with simultaneous regeneration of the bed has confirmed the efficiency of biogas conditioning. Such a solution contributes to a safe and reliable operation of the cogeneration system for generating energy from a renewable source, which in turn contributes to the optimization of energy.

Opis:

The article introduces a method of performing a radio link quality assessment based on the Link Quality Indicator (LQI) which will be calculated for every system that is available. The method presented has been developed during the netBaltic project completed in Poland and generally applies to the so-called maritime zone A, i.e. the sea area where ships are still within the range of shore-based radio communication systems, particularly 3G/LTE cellular networks. The algorithm was developed based on the results of measurements obtained during two separate campaigns. That measurement data served as a basis for the method’s initial assumptions and was utilized during the method’s verification.

Opis:

This article analyses sustainable development indicators for the assessment of bioproducts. It also determines criteria for the operationalization of bioproduct assessment on the basis of available literature on the subject and the opinions of entrepreneurs producing packaging made of petroleum derivative materials. The results of literature and questionnaire studies indicate that indicators used for the assessment should accurately reflect the process or state of affairs they present, and be clear for every stakeholder throughout the entire supply chain.
Artykuł miał na celu wskazanie ścieżki wyboru wskaźników zrównoważonego rozwoju do oceny bioproduktów. Jest próbą wyznaczenia kryteriów operacjonalizacji oceny bioproduktów na podstawie dostępnej literatury przedmiotu oraz opinii przedsiębiorców produkujących opakowania z tworzyw ropopochodnych. Wyniki badań literaturowych oraz ankietowych wskazują, że  wskaźniki stosowane do oceny powinny dokładnie odzwierciedlać proces lub stan rzeczy, który prezentują, być zrozumiałe dla każdego interesariusza na całym łańcuchu dostaw.
