Geology and hydrocarbon resources of the continental shelf in Russian Arctic seas and the prospects of their development

The overall jump in global demand for gas, and especially oil, gives rise to particular concern regarding mankind’s energy future. In the middle and late 21st century, the crucial role in securing oil and gas supply of mankind will be played by sedimentary basins in the Arctic Ocean deep-water area, including those of the continental shelf in Russia’s Arctic seas. There is a 0.90 probability that the initial in-place resources of hydrocarbons in the Arctic Ocean will be greater than 90 Btoe. The estimates predict the rise of oil and gas industries on the Arctic shelves in the near future.     

Urgent issues in replenishment of hydrocarbon mineral and raw materials base in present-day Russia

The article deals with current problems of exploitation and pre-exploitation measures in oil and gas resource replenishment in Russia. Specific procedures are proposed to be taken at different levels of state administration for improving the efficiency of reserves replenishment. The public private partnership is suggested as one of the effective means to solve the problem. The level of the state's involvement in funding and management during regional exploration and prospecting survey is discussed. A systemic approach and a set of criteria for assessing the exploration success rate (at different stages) are recommended for use by the state, as subsurface owner, and for operating companies. In addition, several recommendations and action-oriented proposals are given for preparation of licensing programs that will ensure the preset rates of oil and gas reserves replenishment in the region.     

Effect of dietary docosahexaenoic acid on lipogenesis and lipolysis in black sea bream, Acanthopagrus schlegeli

1 IntroductionIt is well known that varying dietary fatty acidprofile affects the tissue fatty acid composition and e-ven the growth performance in fish ( Bell et al.,2002; Figueiredo -Silva et al., 2005; Harel andPlace, 2003; Schulz et al., 2005; Tocher et al.,2003). Docosahexaenoic acid (DHA), an importantessential fatty acid for marine species, has the effectnot only on the fatty acid profile of fish body tissue,but also on biological and physiological conditions(Ishizaki et al., 2000; …
