Interaction of polyoma virus, specific antibody, and complement has been studied. Firm evidence has been gathered that C1 through C3 and not C5 through C9 enhance neutralization of virus-antiviral antibody (V-Ab) complexes. C enhancement of neutralization occurs primarily by agglutination of V-Ab complexes and not by virion lysis or attachment of large protein molecules to the V-Ab complex. In ...

Ultramafic rocks of the ophiolitic complexes are prone to alteration and degradation, and therefore, ease of mobility of heavy metals such as nickel (Ni), chromium (Cr), cobalt (Co), lead (Pb), and vanadium (V), resulting in environmental hazards. The ultramafic rocks of the ophiolitic realm of Kurdistan province, west of Iran, show field and compositional evidence for such hazardous conditions...

Negotiation is a complex human activity and even in its most basic form consists of three elements: communication, strategy and bid evaluation. The elements are exactly the same in automated negotiation. In this paper we present four possible approaches for bid evaluation and strategy but we mainly focus on the communication aspect of the negotiation. Communication lends itself well to be speci...

This contribution assesses the availability of catabolic energy for microbial life during water-rock reactions in the flanks of mid-ocean ridges, where basaltic and ultramafic rocks interact with circulating seawater. In addition to equilibrium thermodynamic computations, results for kinetic reaction paths are presented. In these calculations, it is assumed that dissolution of olivine and basal...

antivenoms have been used successfully for more than a century and up to now constitute the only effective treatment for snakebites .the production of antivenin started long time ago when the calmette was prepared the antivenom in 1894.the method currently used to prepare antivenom by most of the manufacturers are originated from the method of pope which was develop in 1938. several new appr...
