Limited reserves of oil and the increasing environmental effect of its usage as a motor fuel represent global issue related to the constantly increasing number of motor vehicles. Therefore, the reduction of the fossil fuel consumed and the emission produced in internal combustion engines is the primary goal of the development of motor vehicle propulsion systems. In that sense, the present and the future of motor vehicles relies on hybrid drive systems, electric drive systems and drive systems which use hydrogen as a fuel (either by its combustion or by production of electric energy with the help of fuel cells). In this paper, the authors have presented the aforementioned motor vehicle propulsion systems by explaining their function and design, their basic elements and their functions. Authors have also analysed advantages and disadvantages of the mentioned propulsion systems in comparison to conventional internal combustion engine based systems, both technically and environmentally speaking, but also in relation to available infrastructure and energy resources.

Objective: The article discusses the possibility of using hydrogen as a motor fuel for locomotives. Methods: The advantages and disadvantages of various types of the aggregate state of hydrogen for use as fuel are analyzed, as well as options for placing hydrogen fuel on board locomotives. Results: Possible ways of equipping locomotives with a supply of hydrogen fuel have been determined. Prac- tical importance: The use of hydrogen as a vehicle fuel is environmentally friendly. Considering op- tions for its application allows us to identify trends in the introduction of this fuel in the railway transport of Russia

The article deals with the issues of environmental safety in the operation of motor vehicles, which are one of the leaders in greenhouse gas emissions into the environment. The level of motorization of the country's cities, providing the social side of life, proportionally leads to the development of environmental problems. The article considers the main factors of transport use in different regions of Kazakhstan and their negative impact on the environment. The analysis of the key problems of public transport, more than a third of which are the percentage of greenhouse gas emissions and harmful substances into the atmosphere. The main directions of environmental safety, the necessity of methodological and methodical study on a qualitatively new basis of the problems of the use of natural gas as an alternative motor fuel. The foreign experience of using fuel from alternative sources is analyzed.

Potential Use

The origin of mica polytypes has long been a challenging problem for crystal- lographers, mineralogists and petrologists. From the petrological point of view, interest in this field arose from the potential use of layer stacking data to furnish further informations about equilibrium and/or kinetic conditions prevailing during the crystallization of the widespread mica-bearing rocks. From the compilation of previous experimental works dealing with the occurrence domains of the various mica "polymorphs" (1Mr, 1M, 2M1, 2M2 and 3T) within water-pressure vs temperature fields, it became clear that most of these modifications should be considered as metastable for a fixed mica species. Furthermore, the natural occurrence of long-period (or complex) polytypes could not be accounted for by phase considerations. This highlighted the need of a more detailed kinetic approach of the problem and, in particular, of the role growth mechanisms of basal faces could play in this crystallographic phenomenon.

Aerosol samples were collected in Phoenix, Arizona on eleven dates between July 1989 and April 1990. Elemental compositions were determined for approximately 1000 particles per sample using an electron microprobe with an energy-dispersive x-ray spectrometer. Fine-fraction samples (particle cut size of 1 to 2 μm) were analyzed for each date; coarse-fraction samples were also analyzed for four of the dates.The data were reduced using multivariate statistical methods. Cluster analysis was first used to define 35 particle types. 81% of all fine-fraction particles and 84% of the coarse-fraction particles were assigned to these types, which include mineral, metal-rich, sulfur-rich, and salt categories. "Zero-count" particles, consisting entirely of elements lighter than Na, constitute an additional category and dominate the fine fraction, reflecting the importance of anthropogenic air pollutants such as those emitted by motor vehicles. Si- and Ca-rich mineral particles dominate the coarse fraction and are also numerous in the fine fraction.
