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...

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...

Abstract Russian thistle, also known as tumbleweed ( Salsola spp.), is a problematic invasive plant found on natural and working landscapes. On California rangeland, we tested the singular interactive treatments of grazing, herbicide, seeding to determine how these approaches might influence cover across 5-yr experiment. Total declined by 3% annually during study. A single spring treatment chlo...
