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.

Opis:
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.

Opis:
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.

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.
