The trends in the development of hydrocarbons Caspian shelf water area Russian Federation by domestic and foreign companies are analyzed. In accordance with these trends, national-political priorities for formation an oil gas chemical cluster national subjects zone Pre-Caspian substantiated.

The Ponto-Caspian amphipod Obesogammarus obesus (Sars, 1894) was first recorded in the Rhine River near Koblenz, Germany in October 2004. Additional records of small numbers of O. obesus from the same location in 2005 and 2006 indicate that this alien species may have become established in the central section of the Rhine River. Ship transport via the Main-Danube Canal, connecting the Danube ba...

A total of 48 female spirlins Alburnoides sp. from the Kesselian stream (South Caspian Sea basin, northern Iran) were examined during a period from July 2008 to June 2009 to obtain data on fecundity, and to determine the spawning season of this carp. The mean absolute fecundity of females spirlin was 1722.92 (653.88) eggs. The fecundity has positive correlation with the size of the female. The...

background: brucellosis is a febrile zoonotic infectionand has worldwide distribution among humans as well asanimals. although the seroprevalence of brucellosis in variousanimals has been described in iran, there is only one report onequine brucellosis in the region. objectives: this study wascarried out to determine the seroprevalence of brucellosis inracing clubs and private horse owners in t...

embryonic stem cells (escs) are originally derived from the icm of blastocysts and are characterized by their ability to self-renew and their pluripotencies. only a few reports have been published on esc isolations and line establishment in animals, even fewer in horses. however, it is still important to isolate equine escs for animal biotechnology and therapeutic applications. in the present s...

substitution at codon ser315 of katg gene, a reliable marker for isoniazid (inh) resistance and proliferate in spite of the loss of cell wall is called an l- form. unstable l- forms can convert to normal cells but stble l-forms can not.cell wall - deffective state may be induced spontaneously or through the action of an appropriate agent such as antibiotic interfering with the synthesis of cell...

A solid-phase extraction (SPE) method for sample clean-up and preconcentration followed by reversed-phase high-performance liquid chromatography (RP-HPLC) with uv detection is reported for determination of polycyclic aromatic hydrocarbons (PAHs) in the caspian seawater. A good resolution was obtained using acetonitrile:water (40:60) as mobile-phase for separation of these compounds. The effect ...

Nowadays, advanced turning processes are extensively being adopted to perform different types of operations such as straight turning, taper on Hastelloy, Nimonic, and Inconel, stainless steel, tool steel fabricate better quality cylindrical rotating parts miniature-bars, miniature-pins, miniature-electrodes, miniature-tools. This paper presents a review the previous research conducted miniature...

Aerial surveys of Caspian seals on the winter ice field in Kazakhstan territorial waters were carried out in February 2005 and 2006 to assess the annual pup production for the species and natural predation on newborn pups. Estimated pup production was 21063 in 2005 and 16905 in 2006 (including an estimated figure for pups born in Russian territory in each year). The breeding population size of ...
