شناسائی پوشش گیاهی و بررسی انتشار جغرافیائی گیاهان هر منطقه، مبنای بررسیها و تحقیقات اکولوژی آن منطقه محسوب میشود. هدف پژوهش حاضر معرفی فلور، شکل زیستی و پراکنش جغرافیائی گیاهان منطقه بیابانی آران و بیدگل است. این منطقه با مساحت 605100 هکتار در 5 کیلومتری شمال آران و بیدگل قرار دارد. نتایج نشان داد، مجموعه گیاهان این منطقه، بالغ بر 347 گونه گیاهی متعلق به 58 تیره و 230 جنس است. از مجموع 230 ...
Since the first case of AIDS was identified in 1985, Russia has maintained a low HIVseroprevalence rate, currently at 0.05. However, there are signs of an emerging HIV/AIDS epidemic fueled by several factors. As of September 1999, a total of 19,105 HIV infections were registered, although the estimated number exceeds 50,000. The most recent trend in HIV/AIDS transmission is through injecting dr...
We discuss Coleman’s theorem asserting the absence of a spontaneously broken continuous symmetry and Goldstone bosons in the quantum field theory of a free massless (pseudo)scalar field in 1+1–dimensional space–time (Comm. Math. Phys. 31, 259 (1973)). We show that Coleman’s theorem is erroneous. We prove that the main signature for the absence of Goldstone bosons, a vacuum state, invariant unde...
The Funding statement was erroneously left out of this publication. The publisher apologizes for this error. The Funding statement should read: "This research was supported by the Russian Foundation for Basic Research (RFBR; grant 14-04-00301) to SVT. Funding for DNA barcoding analysis at the Biodiversity Institute of Ontario was provided by grants from the Natural Sciences and Engineering Rese...
It is demonstrated that local quark-hadron duality prescription applied to several exclusive processes involving the pion, is equivalent to using an effective q̄q (two-body) light-cone wave function Ψ(LD)(x, k⊥) for the pion. This wave function models soft dynamics of all higher q̄G . . . Gq Fock components of the standard light-cone approach. Contributions corresponding to higher Fock components...
The International 0-group fish survey in the Barents Sea (1965-2002) aimed to give initial indication of the recruiting year class strengths. Since 2003 the 0-group survey has been a part of a Joint Norwegian-Russian ecosystem survey of the Barents Sea, conducted by IMR (Norway) and PINRO (Russian Federation). The electronic 0-group databases were missing some data and contained errors, therefo...
