WE SHOULD BE PREPARED TO SMALLPOX RE-EMERGENCE

We should be prepared to smallpox re-emergence

The review contains a brief analysis of the results of investigations Dustpan conducted during 40 years after smallpox eradication and directed to study genomic organization and evolution of variola virus (VARV) and development of modern diagnostics, vaccines and chemotherapies of smallpox and other zoonotic orthopoxviral infections of humans.Takin

Longwing (Heliconius) butterflies combine a restricted set of pigmentary and structural coloration mechanisms

Abstract Background Longwing butterflies, Heliconius sp., also called heliconians, are striking examples of diversity and mimicry in butterflies.Heliconians feature strongly colored patterns on their wings, arising from wing scales colored by pigments and/or nanostructures, which serve as an aposematic signal.Results Here, we investigate the colora

Influence of carbon on hydrogen retention in molybdenum for nuclear material application: A first-principles investigation

Mo has been applied to nuclear material, in which H and carbon impurities are unavoidable.In view of this, we have studied the effect of carbon on the H retention in Mo using first-principles simulations.In perfect Mo, there is always Collections repulsion between H and carbon, and impurity carbon cannot capture H atoms.With the appearance of vacan
