Opis:
Artisanal and small-scale mining (ASM) - small sized, largely unrecognized, rudimentary, and an informal form of mining - occurs in more than 70 countries around the world and is mainly hailed for its socioeconomic benefits and reviled for its environmental devastation. As a result, many people are confused about the future of ASM. In Ghana, the government banned ASM in 2017 and formed a security taskforce drawn from the military and police to crack down on nomadic and local ASM workers who defy the ban. This approach is unsustainable, deals less with the fundamental problems, and increases poverty among the already impoverished local populations who depend on this type of mining as their only means of livelihood. To support the argument for sustainable reforms, revenue growth decomposition and growth accounting analyses were performed to determine the factors shaping ASM revenue over 25 years (1990-2016). Results show that production (gold output) is the most important factor that influences revenue growth from ASM, contrary to the usual view that the price of the metal is mainly responsible for the increase in revenue. Thus, increasing labor hours in ASM could significantly increase mining revenue, reduce unemployment, and improve local commerce. We strongly conclude that sustainable reforms such as increasing local participation in decision making, education and training, adoption of improved technology, strengthening regulatory institutions, legislation and enforcement of enactments, and the provision of technical support and logistics could ensure socio-environmental sustainability.

Opis:
Filtration plays a major role in managing the rapid increase of environmental pollution and deterioration of atmospheric air quality. One of the most damaging noxious gases in the atmosphere is toluene, which is a common gas that appears in crude oil and is used in various production processes. The adsorption behaviour of activated carbon was examined in dependence of the concentration, temperature and relative humidity. The results showed that increasing air temperature decreased the time to reach the maximum saturation ratio, which occurred due to the increasing pore diffusion coefficient and pore diffusion rate.

Opis:
The traditional use of fossil-based fuels is now widely considered unsustainable because of depleting their natural resources. Potential substitutes of fossil fuels are oils of renewable origin such as various vegetable and non-edible oils. The aim of using these oils or their methyl esters (biodiesel) is to establish and maintain a balance between agriculture, economy and environment protection. However, realizing the increasing demand of raw materials currently used can be achieved not only by increasing the production area but also by introducing new materials or technologies. The article presents and evaluates modern raw fuel components that are currently being investigated. Furthermore, the article deals with the dual fuel combustion technology in detail, with which the processed fuels are becoming available for use in Compression Ignition (CI) engines, where conventional blending is difficult or their use exclusively in diesel engines is economically unjustified. In case of dual fuel engine systems, the primary fuel, such as (wet)ethanol, methanol, LPG, H2 etc. is injected into the intake manifold of the engine and the premixed mixture simultaneously produced is ignited by the pilot diesel fuel as secondary fuel injected directly into the engine cylinder. This technology can significantly reduce exhaust emissions and can slightly increase engine efficiency. The achievements in this field and recently obtained results by the author and his research group are also presented. Exhaust emissions, performance and combustion characteristics were measured and analyzed with respect to several operating parameters as follows: premixed ratio (rp), pilot timing and engine load.

Opis:
Processes of the combustion of liquid fuels and solid are more complex than combustion of fuel gases. With reference to liquid fuels occur additionally processes of vaporization of the fuel, and with reference to solid fuels - decomposition of the solid phase with processes of melting and vaporization, pyrolysis, or gasification. This simultaneous and also different influence of different parameters is sometimes a reason of incorrect interpretation of experimental results. The study of the theoretical model of the combustion process concerning of liquid and solid fuels and which then the model takes into account also the gas- phase, because combustion processes take place in this phase, and occurs the interaction of the phase gas- and liquid or the solid one. The theoretical model is presented basing on experimental initial researches realized in a model with reference to liquid fuels and solid ones. Researches realized in the constant volume chamber with measurements of the pressure during the process of the combustion with the use of quick photography and with measurement of the distribution of the velocity in the spray of the fuel and droplet measurements by means the laser Doppler equipment LDV and PDPA. There were obtained a good agreement of findings experimental researches with the theoretical model. Generally on the combustion velocity of liquid fuels and solid one significant influence has a kind (laminar, temporary and turbulent) and the thickness of the thermal boundary layer.

Opis:
Limiting emissions of harmful substances is a key task for vehicle manufacturers. Excessive emissions have a negative impact not only on the environment, but also on human life. A significant problem is the emission of nitrogen oxides as well as solid particles, in particular those up to a diameter of 2.5 microns. Carbon dioxide emissions are also a problem. Therefore, work is underway on the use of alternative fuels to power the vehicle engines. The importance of alternative fuels applies to spark ignition engines. The authors of the article have done simulation tests of the Renault K4M 1.6 16v traction engine for emissions for fuels with a volumetric concentration of bioethanol from 10 to 85 percent. The analysis was carried out for mixtures as substitute fuels – without doing any structural changes in the engine's crankshafts. Emission of carbon monoxide, carbon dioxide, hydrocarbons, oxygen at full throttle for selected rotational speeds as well as selected engine performance parameters such as maximum power, torque, hourly and unit fuel consumption were determined. On the basis of the simulation tests performed, the reasonableness of using the tested alternative fuels was determined on the example of the drive unit without affecting its constructions, in terms of e.g. issue. Maximum power, torque, and fuel consumption have also been examined and compared. Thus, the impact of alternative fuels will be determined not only in terms of emissions, but also in terms of impact on the parameters of the power unit.

Opis:
Ukształtowanie rzeźby terenu ma podstawowy wpływ na zjawiska przyrodnicze zachodzące na powierzchni Ziemi. Dyrektywa 2000/60/WE (Ramowa Dyrektywa Wodna) Parlamentu Europejskiego i Rady Europy (23.10.2000) nakazuje wprowadzenie obowiązku zrównoważonego gospodarowania zasobami wody, między innymi poprzez ochronę przed pogarszaniem się stanu wód, ekosystemów wodnych oraz ekosystemów lądowych i terenów podmokłych zależnych od wody. Geneza powstania terenów podmokłych oraz zbiorników naturalnych wody związana ze strukturą i typem gleb, ukształtowaniem terenu, ze spływem powierzchniowym wód w cyklu hydrologicznym oraz z wodami podziemnymi, które przy pochyłej warstwie nieprzepuszczalnej występują w postaci strumienia płynącej wody, znajdującej ujście w postaci źródeł lub sap. Ukształtowanie terenu jest funkcją grawitacyjnego zniesienia stokowego gleby będącego gęsto-plastycznym biegiem złoża powierzchownego po powierzchni nachylonej opisywanym równaniem Szwedowa-Binghama. Ruch gleby na skosach ustaje po osiągnięciu nachylenia końcowego. Stanem końcowym będzie profil H = H0, na którym krusz już jest w warunkach stabilności. W miarę upływu czasu kształt profilu dowolnego zbocza stanie się regularny niezależne od jego stanu pierwotnego, przy czym w jego dolnej części uformuje się strefa akumulacji kruszy, która przy określonych warunkach hydrologicznych i glebowych stanowić będzie naturalną zaporę wód powierzchniowych i zaskórnych. Celem prowadzenia badań było opracowanie metod oceny stabilności ukształtowania terenu z wykorzystaniem nowoczesnych metod fotogrametrycznych i geoinformacyjnych oraz pozyskiwania obszarów zagrożonych podtopieniem i zanieczyszczeniami związanymi z powierzchniowymi oraz gruntowymi spływami wód.
Landscaping has a major impact on the natural phenomena that occur on the surface of the Earth. Directive 2000/60/EC of the European Parliament and of the Council of Europe (23/10/2000) prescribes an obligation of sustainable management of water resources, including by protecting them against deterioration of water, aquatic and terrestrial ecosystems and wetlands dependent on water. Origins of wetlands and natural water reservoirs associated with the structure and the type of soil, topography, the surface flow of water in the hydrological cycle and the groundwater that emanates as a stream water under sloping impermeable layer. The Szwedow-Birghman equation describes the function of gravity relating flow of terrain which is density-plastic soil on slope surface. The movement of soil on sloping angle stops after reaching the final state. The final state will profile H = H0 that shows the terrain in stability condition. Over time, the shape of any profile will become regular independent of its original condition, and in its lower part forms a zone of accumulation, which under certain conditions, hydrological and soil will be a natural barrier for surface and underground water. The aim of this study was to develop methods to assess the stability of the terrain using modern methods of photogrammetry and geospatial and gain areas at risk of flooding acquisition and pollution associated with the flow of surface water and groundwater.

Opis:
The goal of the paper is to focus on the problem of emission of harmful compounds e.g. NOx, SOx and CO2 from seagoing ships to environment. The VI Amendment to MARPOL Convention concerning prevention against air pollution by seagoing ships, brought into practice in May 19th 2005, forced ship owners to use means for reduction of environment harmful substances emission to atmosphere. They may comprise construction and operating methods. Energy Efficiency Design Index (EEDI) is one of the tools enabling implementation of the above-mentioned regulations, compulsory to all new design and build ships. However, for units already in operation, the problem requires a different approach. The article presents various methods of reduction of toxic substances and CO2 by seagoing vessels in order to adapt to the requirements of the Convention and other legal regulations in this regard. As an example, the analysis has been presented concerning possibilities of adjustability of cruise ferries and Ro-Ro vessels operating on the Baltic Sea to the requirements of Annex VI of the MARPOL Convention. Some possible solutions have been shown focusing on selection of system of combustion of hydro-fuel emulsion in main drive engine. Article contains description of introducing water to the combustion chamber methods and water influence on the combustion process.

Opis:
The test procedure for the pollutant emissions from light-duty vehicles is currently under verification carried out at the international level. For this purpose, GRPE (Groupe des rapporteurs sur la pollution et energie) – the body developing UNECE regulations proposals - has set up a task group WLTP (Worldwide harmonized Light vehicles Test Procedure) which is supposed to prepare a new GTR (Global Technical Regulation) relating to this procedure. The development of light-duty vehicles, leading to the reduction of pollutants emissions, caused the increase of the requirements for their test procedure. A large number of factors associated, inter alia, with the test equipment affects its accuracy, repeatability and reproducibility. In the ongoing analysis attention is paid even to factors, which affect test results in a relatively small way, and which have been overlooked yet. One of the problems to which attention is paid is the impact of pollutant concentration in the dilution air in the CVS (constant volume sampler) system on test results. The CVS principle is accepted as the standard method to determine light-duty vehicle exhaust emissions on chassis dynamometer test cells worldwide. It was introduced in the early 1970s. One of its drawbacks is that it introduces an error resulting from the fact that the contractual DF dilution factor, rather than the actual dilution ratio DR, is used for the correction of concentration measurement results. The article discusses this error for different type of engines used in light-duty vehicles and different pollutants subject to measurements.

Opis:
Regeneration of parts is the most correct form of use of worn out components and contributes, among others, to reduce CO2 emissions. In the case of elements of fuel injector systems, very high precision is required and such regeneration should be carried out using the original parts. It also requires testing on the original testing stands of these manufacturers, which very often characterized by the fact that it is not possible to perform a short test, which means that it is only possible to perform a time-consuming comprehensive test. An unquestionable advantage in some cases would be the possibility of preliminary verification of the correct operation of the regenerated subassembly without the need for a full time-consuming test. In the present situation, only after completing a time-consuming comprehensive test of the diagnosed element of the injection system, it is often necessary to carry out its disassembly, replacement or correction of one of the components and reassembly with the next time-consuming test. In the case of low unemployment in the labour market, this is extremely unfavourable, and it is often not possible to organize work in such a way that the diagnostic test of the subassembly takes place without the participation of an employee. On the basis of the analyses presented in this article, carried out in the research and development department in company whose employee is one of the co-authors, it can be stated that in the current situation on the labour market where skilled workers are required to work and for the development of science is the most purposeful recognition of the possibility of using vibroacoustic signals to shorten time of tests, which with a high probability may end in a negative result. The preliminary analysis carried out, show that limitation of diagnostic time can be over 35%.

Opis:
Recently, a lot of attention was paid to the improvement of methods which are used to air quality forecasting. Artificial neural networks can be applied to model these problems. Their advantage is that they can solve the problem in the conditions of incomplete information, without the knowledge of the analytical relationship between the input and output data. In this paper we applied artificial neural networks to predict the PM 10 concentrations as factors determining the occurrence of smog phenomena. To create these networks we used meteorological data and concentrations of PM 10. The data were recorded in 2014 and 2015 at three measuring stations operating in Krakow under the State Environmental Monitoring. The best results were obtained by three-layer perceptron with back-propagation algorithm. The neural networks received a good fit in all cases.
