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

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.

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.

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.

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.

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:

The paper presents the ecological indicator values for 360 lichen species noted in Poland. For the given species estimated were the climatic indicators (light, temperature, moisture) and the edaphic ones (trophicity, habitat acidity). The estimate is based mainly on field studies and Polish lichenological literature. Presented are also the dynamics tendencies, i.e expansion or dieback of the analyzed species. According to papers by Polish authors, concerning various groups of plants, used were five degrees' scales of the analysed indices.

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.
