THE SENSITIVITY OF VARIOUS CURRANT SPECIES AND VARIETIES TO TRACHEOMYCOSIS ^{[№ 7 ' 2016]}
Currently mycotic wilting (tracheomycosis) is widespread. It caused ubiquitous significant reduction of areas which field in black currant. This resulted in negative environmental, economic and social consequences. Over the past decade in the southern Orenburg region, as in other regions of Russia, Kazakhstan, Ukraine verticilliaceous wilting of black currant, which caused its death, was registered. Wilting is not found on golden and white currant (Ribes aureum, R. niveum). Redcurrant (R. rubrum) is slightly damaged, in black currant (Ribes nigrum), on the contrary, there is destruction of certain varieties up to 90 %. Based on the results of our own research, the most resistant to tracheomycoses varieties — Luchezarnaya, Yadryenaya, Globus and several other varieties the resistance of which was estimated to be 4-5 pointswere revealed. The least resistant varieties were Selechenskaya, Rusalochka, Vologda, and others. The main pathogens are presented by fungi Fusarium spp., Alternaria spp., Verticillium spp. Activation of fungi in the second half of vegetation (July — September) was revealed. This is due to the temperature increase against low water supply in the designated months within the Orenburg region. It was found that in the case of complex Verticillium spp. and Fusarium spp. infection wilting followed by plant death was observed. Verticillium fungi should be considered to be the most probable cause of death of black currant. Species differences in the production of tannins found in the bark in greatest numbers and perimedular zone of golden, white and red currants were revealed. The least number was found in the cambium of black currant. The problem of tracheomycotic wilting of black currant can be successfully solved by means of selection and cultivation of resistant varieties to the causative agents. The obtained results allow us to advance in the understanding of formation mechanism of infectious stability of black currant, and to identify the ways of therapy and prevention of mycotic wilting of Ribes nigrum.

SCIENTIFIC-TECHNICAL PROGRESS AND SCIENTIFIC-ENGINEERING PROBLEMS OF INDUSTRIAL SAFETY ^{[№ 9 ' 2015]}
It is shown that to ensure the safety and viability of the planet's growing population requires not only a constant increase in resources, but also to avoid the risks associated with the use of scientific and technological progress. Start of civilized management of hazardous industrial processes and facilities in the country was initiated adoption of the Federal Law № 116-FL of 21.07.1997 (12.21.2014), where the main requirements for industrial safety. For example of the Orenburg gas complex, the possible risks at hazardous production facilities at the impact of natural character illustrated. Industrial safety as an area of scientific activity is regarded. The basic stages of its development and improvement, including mathematical methods and computer technology risk prediction, identification of the causes of disasters, the development of new diagnostic tools and technical methods to assess the mechanics of deformation and fracture.

PALEOECOLOGY OF SMALL FORAMINIFERA IN PECHORA PROVINCE ^{[№ 2 ' 2006]}
At the first time paleoecology of Perm Foraminifera of Boreal region is considered in this article. Regularities of small Foraminifera popularity and allocation in sediment are distinguished here. Interaction of Foraminifera inside of paleobiocenosis is established in this work too.
