Opis:
The development of marine diesel engines has so far been directed towards increasing their power, reducing fuel consumption, burning fuels of the lowest possible quality and the extension of operation time. The rising pro-ecological pressure has made atmosphere pollution by exhaust gases of marine engines one of the main problems of environmental protection of recent years. The Gdansk Bay area, just like sea ports or coastal regions, is vulnerable to the effect of noxious compounds contained in vessel exhaust gases, besides those coming from industrial plants, power plants or vehicles. This concerns vessels both in ports and in the roads. In order to determine the share of vessels in environmental pollution and to counteract the harmful effects of toxic compounds in marine engine exhaust gases, it is necessary to know the emission values of these compounds from particular vessels, which is possible with the knowledge of their movement parameters, concentration values of particular compounds for these parameters and the atmospheric conditions. The report presents problems of modelling the NOx emission in exhaust gases from main marine Diesel engines, such as problems with construction special models describing the marine vessels movement or define real value of toxic compounds emission.

Opis:
An overview of long-term, sysiematic observations of trace gas composition of the atmosphere over southern Poland is given. Three major greenhouse gases (CO2, CH4, N2O) and selected halocarbons (freons F-11, F-12 and F-113; chloroform; 1,1,1-trichloroetane; carbon tetrachloride; sulphur hexafluoride and trifluoromethyl sulphur pentafuoride) were monitored. Measurements were performed at two locations of contrasting characteristics: (1) the high-mountain site Kasprowy Wierch, High Tatras, representing atmospheric conditions relatively free of local influences, and (2) two sites located in the Kraków agglomeration, representing a typical urban atmosphere. The data available for Kraków and Kasprowy Wierch were compared with the Mace Head data, representing a marine regional background. The impact of continental sources for some of the measured gases is clearly seen in the Kraków and Kasprowy Wierch records. The mean offset between CH4 concentrations recorded at Kasprowy Wierch and at Mace Head for the period 1998-2012 is 20.7 ppb and stems from continental emissions of this gas originating mainly from anthropogenic activities (leaks of natural gas distribution networks, landfills, livestock). For N2O, a similar offset of ca. 1 ppb for the period 2009-2012 was observed. Although the long-term concentration trends of selected halogenated compounds measured in Kraków coincide in general with the respective trends in Mace Head data, the Kraków records contain numerous spikes and periods of enhanced concentrations, reflecting the impact of local sources of these compounds. The impact of a legislative framework enforced in Poland in July 2002, regulating the trade, storage and disposal of ozone-depleting substances, is visible in the Kraków record of halogenated compounds.

Opis:
Endogenous fires are currently one of the most common threats in hard coal mines. They are very dangerous for the staff and can cause very large economical loses. Therefore, the scope of activities aimed at limiting the possibility of these fires and reduction of their consequences constantly broadens. The paper presents the results of research aimed at determining the efficiency of the ventilation system applied to reduce the risk of endogenous fires in the areas where inert gases are used. The calculations included carbon dioxide and nitrogen. Inertisation is one of the ways of combating endogenous fires. This method is included in the developed comprehensive method to reduce the possibility of these fires. The results obtained and the method developed and later applied, should have a significant impact on improving the safety of operations in the scope of occurrence and consequences of endogenous fires.

Opis:
Costs for tolling a motorway in Poland should take into account not only profits of owners and managers, but also difficulties and losses incurred by road users. Lack of smoothness of travel as well as high tolls do not have a positive impact on the country's economic development. The nervousness and stress of drivers and passengers trapped in cars standing in traffic jams in front of the gates on motorways - they indicate an important social problem. The costs of fuel burnt during forced stops, costs of harmful effects on the environment, pollution from car exhaust emissions while waiting on the highway in front of the gates – they all are a significant burden. Failure to ensure the conditions for a smooth ride causing the need to wait on the highway in front of the gates is an example of disregarding people, wastage and deliberate harm to the environment for disproportionate profits charges for using the highways.

The results concerning emission of gases from two commercial graphite protective coatings for moulds and cores (water and alcoholic) are given in the hereby paper. Investigations were performed in two systems. One of the systems was corresponding to conditions occurring inside the mould cavity immediately after its pouring with liquid metal (Method 1), while the second was simulating conditions deep inside the mould at a certain distance from the casting (Method 2). Investigations were carried out in the CO2 atmosphere and in the air. The water protective coating generated 1.5 to 3 times larger volume of gases than the alcoholic coating (in dependence on the measuring method and atmosphere). The smallest differences occurred in the air atmosphere, while the largest in the CO2 atmosphere.

Opis:
Methane concentrations in natural gases accumulated in the Lower and Upper Badenian and Lower Sarmatian reservoirs of the Bilche-Volytsia Unit in the western part of the Ukrainian Carpathian Foredeep usually exceed 96 vol%. Methane was generated by microbial reduction of carbon dioxide in the marine environment. Microbial methane and ethane were produced mainly during sedimentation of Miocene clays and muds. It is possible that this microbial process continues today. Higher light hydrocarbons (ethane in part, and mainly propane, butanes and pentanes) were generated during the diagenesis and the initial stage of the low-temperature, thermogenic processes from Type III and III/II kerogen deposited in Miocene strata and/or Middle and Upper Jurassic basement rocks. Limited variations in the values of geochemical hydrocarbon indices and stable isotope ratios of methane, ethane and propane with the depth indicate similar gas generation conditions within the whole Miocene succession. The microbial gases (methane and partly ethane) generated during microbial processes within the Miocene strata later migrated to the Upper Jurassic and the Upper Cretaceous (Cenomanian) reservoirs of the Mesozoic basement, and to the bottommost Lower Badenian reservoirs of the analysed Letnia, Orkhovychi, Rudky and Vereshchytsia fields. The low hydrogen concentrations within the Miocene strata as well as within the Upper Jurassic and the Upper Cretaceous (Cenomanian) reservoirs of the Mesozoic basement, and within the bottommost Lower Badenian reservoirs are also related to microbial processes. Carbon dioxide and nitrogen, which are common minor constituents, were generated by both microbial and low-temperature thermogenic processes. Moreover, CO2 also underwent secondary processes, mainly dissolution in water, during migration. At least part of the nitrogen accumulated in the Rudky field, which is remarkably high in N2 (96.9 vol%), is probably of atmospheric origin and was introduced to the reservoir by secondary recovery methods.

Opis:
Emissions of greenhouse gases, such as carbon dioxide, methane, dinitrogene monoxide, water vapours and ozone was constant until the end of eighteenth century, and then began to increase. This increase was particularly steep after 1950 and continues until today. It is estimated, that changes in greenhouse gas concentrations in the air, which lasts for more than 200 years, stemmed largely from human activities, including the development of agriculture, transport and industry. The article discusses the problem of the greenhouse effect in terms of emissions of selected gases and components from the motor vehicles. It presents the results of pollutants emissions measurements, including greenhouse gas emissions from vehicles, in some research tests, curried out on the chassis dynamometer. There is assessed the impact on greenhouse gas emissions from different engine sources (exhaust system, fuel system, and crankcase) due to the following fuels: LPG, CNG, petrol, diesel oil and biodiesel. This article is a fragment of greater work devoted determination of emission indicators for greenhouse gases useful in calculation of total emissions by selected transport sectors. There are two interesting conclusion of this work: the first is that for diesel engine significant part of greenhouse gas emissions have PM emissions and the second that for older spark ignition engines equipped with open type fuel systems very important part of these emissions have hydrocarbon emissions from fuel system.

Opis:
Livestock buildings are an important source of ammonia, methane and nitrous oxide. In naturally ventilated buildings for dairy cattle interaction of weather conditions and microclimate parameters in livestock buildings have an impact on the emission of ammonia and greenhouse gases. The aim of the study was to determine the effect of the seasons on the emission of greenhouse gases (CH4, N2O) and ammonia from barns for dairy cows. The study was conducted in 6 free-stall barns located in the Wielkopolska Voivodship, during: spring, summer and fall. The median of CH4 emission factor was 14.8±2.3 g·h-1·cow-1 in spring, 16.9±3.2 g·h-1·cow-1 in summer, 17.3±2.1 g·h-1·cow- in fall. For N2O and NH3 values were 0.085±0.067 g·h-1·cow-1 in spring, 0.120±0.060 g·h-1·cow-1 in summer, 0.062±0.049 g·h-1·cow-1 in fall and 1.13±0.34 g·h-1·cow-1 in spring, 1.17±0.45 g·h -1·cow-1 in summer, 0.77±0.37 g·h-1·cow-1 in fall, respectively. The analysis for all barns showed statistically significant differences in the values of emission factors between seasons (α = 0.05). For NH3 and CH4 they were not observed only between spring and summer, and for N2O between spring and fall (α = 0.05).
Budynki inwentarskie są głównym źródłem amoniaku, metanu i podtlenku azotu. W naturalnie wentylowanych obiektach dla bydła mlecznego wzajemne oddziaływanie warunków pogodowych oraz parametrów mikroklimatu wewnątrz budynków inwentarskich kształtuje emisję amoniaku i gazów cieplarnianych do otaczającego je środowiska. Celem pracy było określenie wpływu pór roku na emisję gazów cieplarnianych (CH4, N2O) i amoniaku z kilku obór dla krów mlecznych. Badania przeprowadzono w 6 oborach wolnostanowiskowych zlokalizowanych w województwie wielkopolskim, w trzech seriach: wiosennej, letniej oraz jesiennej. Mediana wskaźnika emisji CH4 wynosiła 14.8±2.3 g·h-1·szt.-1 wiosną, 16.9±3.2 g·h-1·szt.-1 latem i 17.3±2.1 g·h-1·szt.-1 jesienią. Dla N2O i NH3 wartości te wynosiły odpowiednio 0.085±0.067 g·h-1·szt.-1 wiosną, 0.120±0.060 g·h-1·szt.-1 latem i 0.062±0.049 g·h-1·szt.-1 jesienią oraz 1.13±0.34 g·h-1·szt.-1 wiosną, 1.17±0.45 g·h-1·szt.-1 latem i 0.77±0.37 g·h-1·szt.-1 jesienią. Ogólna analiza dla wszystkich obór wykazała statystycznie istotne różnice w wartościach wskaźników emisji między porami roku (α=0.05). W przypadku NH3 i CH4 nie zaobserwowano tych różnic jedynie dla wiosny i lata, a w przypadku N2O dla wiosny i jesieni (α=0.05).

Opis:
The Dräger probe in the measurement set to the geochemical research of the soil gases composition is inconvenient to use. It's heavy, which are reąuired to operate at least two people. Cumbersome and time-consuming is to place it into the soil by impact method, and often there is fail to reach the planned measurement depth. For this reason, there was designed and made the new modified Dräger probe. The new probe has significantly lower mass and outer diameter. In principle it should be possible to introduce it into the soil by pushing, which will greatly facilitate and accelerate conducting the geochemical research of the soil gases composition.In the autumn of 2014 has been tested the modified Drager probe. The purpose of this study is to assess it suitability to conduct the geochemical research of the soil gases composition. In total there were performed 374 measurements of the soil gases composition at different depths in the 247 measurement points. In 99 cases (26.5%) there was failed to perform the measurement because the soil gases flow rate through the meter was too little. Pulling probe usually allowed to perform the research - in only 6 measurement points (2.4%), it was impossible. The average depth of the measurement point is equal to 0.78 m.

We present density functional theory (DFT) calculation results of krypton and xenon atoms interaction on the surface of uranium dioxide single crystal. A pseudo-potential approach in the generalised gradient approximation (GGA) was applied using the ABINIT program package. To compute the unit cell parameters, the 25 atom super-cell was chosen. It has been revealed that close to the surface of a potential well is formed for xenon and krypton atom due to its interaction with the atoms of oxygen and uranium. Depth and shape of the well is the subject of ab initio calculations in adiabatic approximation. The calculations were performed both for the case of oxygenic and metallic surfaces. It has been shown that the potential well for the oxygenic surface is deeper than for the metallic surface. The thermal stability of immobilising the atoms of krypton and xenon in the potential wells were evaluated. The results are shown in graphs.

Numerical methods can be considered nowadays as once playing the most important role in the combustion process analysis. Paper describes the application of the dual zone model, allowing the analysis of the combustion process in an SI engine with the possibility of estimating 10 different exhaust gases i.e.: CO2, CO, H2O O2, NO, N2, H2, H, O and OH. The research has been carried on a 1.6 litr es four cylinder SI engine, fed with petrol and alternatively with LPG and CNG. In-cylinder pressure for the 4th cylinder of the tested engine has been acąuired for several engine speeds. registered in-cylinder pressure traces p=p((fi), together with the volume variation nii=nii((fi) infunction ofcrank angle, were used in the combustion process simulating calculations. Obtained results made it possible to compare selected parameters describing the combustion process. Obtained results do also prove recognized fact related to the higher temperature necessary to initiate gaseous fuel combustion.

Opis:
Livestock are reared throughout the world, and are an important agricultural product in virtually every country. This animal production systems and climate change are inter-related via complex mechanisms. Animal production influences climate change by emitting greenhouse gases such as methane and nitrous oxide. It is estimated to be the livestock sector is contributing a significant share of global GHG emissions, accounting for approximately two-thirds of direct agricultural emissions and about 14.5 percent of total human-induced emissions when supply chains are considered. Therefore, globally, there is an urgent need to reduce the greenhouse gas (GHG) emissions that cause climate change by at least 80 per cent in wealthy countries and to protect the biodiversity which underpins food production. Dietary manipulation, ionophores, bacteriocins, covered anaerobic digesters, awareness creation and intensifying research and development are among the applicable methane mitigation strategies. Moreover, research bodies are also organizing to deliver findings at an international level; which focuses on the identification and development of technologies and practices to increase food production without increasing green house gases emissions.
