It is known that climate change has an effect on many Deltas all over the world. Egyptian Nile Delta, one of the most dangerous places which may be suffered from risks of climate change. In the current work, an attempt to study the effect of climate change on the Nile Delta has been discussed.

Complex sedimentologic examination of the JV₁¹ oil-bearing bed has been made within the southeastern part of the Yarsomovskij site. The Upper Jurassic beds within the study area were found to be represented by coastal-continental and coastal-marine facies.

The research of motor transport’ influence on a condition of atmospheric air and a solid cover of the Engels city are carried out. motor transport movement on city streets is analysed. concentration of exhaust gases from the motor transport are calculated. Interrelations between quantity of the motor transport, concentration of exhaust gases and pollution of a soil cover are established

Problem for finding the criteria of belonging the vector fields to the set of electromagnetic fields is formulated. The existence and uniqueness of the solution of this problem are investigated. The desired criteria for the set of alternating electromagnetic fields in the frequency domain in the case of isotropic media are formulated. It is shown that these criteria are shared set of alternating electromagnetic fields in linear isotropic media into two subclasses. Are examples of the fields belonging to these subclasses.

On the territory of the Republic, in the Ferghana valley are depleted oil fields, where it was noted the manifestation of hydrogen sulfide, thermal waters. Based on materials from oil exploration and individual hands-on mizhplastovi water were established relationship between hydrochemical and geophysical parameters, the unloading area in faults; delineated the most promising areas of accumulation of hydrogen sulfide waters, increased concentration, determined by their place in the structures Chimion-Kashkarkyr

Over the long and varied geological history of the junction zone of the south-east of the Russian Urals Hercynian plate and formed various types geogidrodinamicheskih systems The article analyzes the emerging and transforming paleogidrogeologicheskih environments conducive to the processes of petroleum, oil and gas, and, at certain moments, the destruction of hydrocarbon accumulations. Estimated cumulative effect of these processes

The Upper Permian ichthyofauna from Vyazniki, Vladimir Region, has been analyzed. The rocks hosting fossil fish bones have been determined to belong to the terminal Permian ichthyofauna subzone Toyemia blumentalis-Gnathorhiza otschevi-Mutovinia sennikovi. An assumption is advanced that upwards in the section replacement of the fish complexes takes place, with some of the representatives pervading into the Triassic. Description of the actinopterygian Mutovinia sennikovi A.

In the course of this work we cast the light on the state of research of the Late Cretaceous sea urchins in the Volga region as well as the development of ideas about their distribution in the rocks of the Upper Cretaceous in the region. Resources used in the research include studies about this group of invertebrates since the beginning of the XIX century up to the present day. It was estab­lished that the vast majority of publications consist of fragmentary information containing mentions of echinoderm remnants findings.

Statistical analysis of the data shows a significant correlation between the magnitude of the curves (GF) and the density (?) of hydrocarbon mixtures in Orenburg, Saratov and parts of the Buzulukskoj basin.

Investigations of soil in the affected area landfill solid waste. Investigated grain size, magnetic susceptibility, acid-base indicator, redox potential, the content of humus in the soil. On the basis of the data obtained in preliminary conclusions about the state of geo-environmental soil cover.
