The paper presents the results of a study on the impact of the cultivation of crops which may serve as a substrate for a biogas plant on the atmosphere. Subjects addressed in the study cover a range of issues related to greenhouse gas (GHG) emissions from this area of agricultural activity. The amounts of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) emitted to the atmosphere in the selected cultivation technologies of beet, maize for silage and grasses were calculated. Emissions of GHG from chemical fertiliser production corresponding to the quantities used in the individual technologies were analysed, and amounts of the emitted above-mentioned pollutants originating from diesel fuel used during agricultural treatments conducted with the use of agricultural machinery were calculated. Emission values were expressed in equivalent units – E CO2eq. The study demonstrated that technologies which result in the highest quantities of emission are maize cultivation technologies – the average value for the study crops is 1 428 490.56 g haˉ¹ CO2eq. The lowest level of pollutants in the form of emitted greenhouse gases originates from grass cultivation and its average value is 904 661.28 g haˉ¹ CO2eq.
The aims of this study were: (1) to characterize the training load structure and the applied training means in typical microcycles of the transition period and the competitive season administered to young soccer players, and (2) to present exemplary training units of the competitive and the transition periods.20 young soccer players (12-13 years old) took part in the study. Jastrzębski's method based on Sozański and Śledziewski was applied to register and monitor the training load. Data was analyzed regarding the information range (general or specific drills) as well as energetic zones (aerobic, mixed aerobic-anaerobic, anaerobic lactate or anaerobic alactate drills).The results of study show crucial differences in the applied training means in the analyzed microcycles. In a typical microcycle of the transition period general drills predominate, while during the competitive period - specific drills prevail. The total effective time of training was longer in the competitive season microcycle. It is a proper relationship according to the theory of sport training.The range of the training load registered in the competitive season is in line with other authors' research where league matches and small-sided games were used particularly often. The studied microcycles in the competitive season can be model ones and can be used in the training process of young football players.
Badania hydrochemiczne rzeki Łososina prowadzono w 2013 r. Wodę do badań pobierano z rzeki na wysokości miasta Tymbark w sześciu punktach pomiarowo-kontrolnych. W pobranych próbkach oznaczono przewodność elektrolityczną właściwą wody oraz stężenie fosforanów, azotu amonowego, azotynowego i azotanowego. Woda Łososiny na całej długości badanego odcinka spełnia wymogi klasy I. Stwierdzono statystycznie istotnie wyższe stężenie azotu azotynowego w punktach 5 i 6 w stosunku do pozostałych badanych punktów. Analiza profilu hydrochemicznego tego odcinka rzeki wykazała niewielki wpływ miasta Tymbark na jakość wody.
Bisphenol A (BPA) belongs to chemicals that are produced in large quantities worldwide. It is commonly used as monomer in polycarbonate synthesis, plasticizer in the production of epoxy resins, as well as an additive for the elimination of surfeit of hydrochloric acid during the polyvinyl chloride (PVC) production. BPA is not only used in the production of plastics intended to a direct contact with food, including plastic packaging and kitchenware, but also in inner coatings of cans and jar caps. There are various routes of human exposure to this substance such as oral, by inhalation and transdermal. The main sources of exposure to BPA include food packaging and dust, dental materials, healthcare equipment, thermal paper, toys and articles for children and infants. BPA is metabolized in the liver to form bisphenol A glucuronide and mostly in this form is excreted with urine. Due to its phenolic structure BPA has been shown to interact with estrogen receptors and to act as agonist or antagonist via estrogen receptor (ER) dependent signalling pathways. Therefore, BPA has been shown to play a role in the pathogenesis of several endocrine disorders including female and male infertility, precocious puberty, hormone dependent tumours such as breast and prostate cancer and several metabolic disorders including polycystic ovary syndrome (PCOS). Because of the constant, daily exposure and its tendency to bio-accumulation, BPA seems to require special attention such as biomonitoring. This observation should include clinical tests of BPA concentration in the urine, which is not only one of the best methods of evaluation of the exposure to this compound, but also the dependence of the daily intake of BPA and the risk of some endocrine disorders.
Mucopolysaccharidoses (MPS) are severe inherited metabolic disorders caused by storage of glycosaminoglycans (GAGs). The level of accumulated GAGs is an important parameter in assessment of the severity of the disease and the efficacy of treatment; unfortunately, biochemical methods are often unreliable and only semi-quantitative. Therefore, finding other methods for estimation of GAG levels and/or assessment of the efficacy of applied therapy is very important. Although monitoring of GAG levels during therapy is crucial, in this work it is proposed that analysis of the ultrastructure of MPS cells by electron microscopic techniques can be considered as an alternative and reliable method for assessment of lysosomal storage. The number of complex lysosomal structures was found to be significantly higher in MPS cells relative to controls, while it decreased significantly in response to either enzyme replacement therapy or substrate reduction therapy. Thus, this parameter, easily assessed by electron microscopy, appears to correspond to the physiological state of MPS cells.
The aim of this study was to determine changes in both aerobic and anaerobic physical capacity as well as in sport-specific skills in footballers as a result of the applied training load within a one-year training period. It was assumed that the type of applied training load would have a significant influence on changes in physical capacity indexes and on differences in soccer technical skills. The tests applied in the research were: Wingate test 30 sec. version for lower extremities (used to assess anaerobic capacity), PWC170 test (used to assess aerobic capacity) and German Football Association test of soccer technique skills known as DFB test (Deutsche Fussball Bund test).The highest values of maximal power (Pmax=11.2 W·kg-1) and maximal total work volume (W=270.1 J·kg-1) obtained in Wingate test were noted at the end of the preparatory season. Statistically significant differences (p≤0.05) of mean values of the maximal power occurred between the first and the second test. No differences were stated between mean values of total work volume. However, aerobic capacity index and VO2max determined by an indirect method reached the highest values at the end of the competitive season and amounted to 18.6 kgm·kg-1·min-1 and 51.8 ml·kg-1·min-1respectively. The best results in soccer technical skills test were registered at the end of the preparatory season (343.6 points) and at the end of the competitive season (340.2 points).It is stated that training load applied had a beneficial influence on changes in physical capacity indexes and results of soccer-related skills.
The aim of the study was to assess the anaerobic threshold (lactate threshold LT) changes during winter and summer preparation period in soccer premier league and first division players. It was assumed that the index value varies depending on the stage of a one-year training cycle.Tests were conducted on the premier league and first division soccer players. Physical capacity tests were carried out at the beginning and at the end of the winter and summer preparation period. The tests covered 3 years: 2008 - 2010. Subjects performed an incremental running test according to Jastrzębski's method. The most important data obtained from this test are: running speed (V/LT) and heart rate (HR/LT) at LT.At the beginning of summer preparations the players' speed corresponding to LT reached the value of 3.69 m/s ± 0.31 m/s, while at the end of this period it increased to 3.86 m/s ± 0.29 m/s. During the winter preparatory season the values of this index were 3.81 m/s ± 0.3 m/s and 3.80 m/s ± 0.21 m/s, respectively.Tested subjects showed lower values of running speed at LT level at the beginning of the summer preparatory season than at its end. At the final stage of the winter preparatory season HR values at LT were significantly lower than at the initial stage of this period.
