Climatology of High Wind Events in the Owens Valley, California

Potential mechanisms for the development of strong winds in the valley are examined. Contrary to the co...

The humoral adaptive immune system of sharks is partly based on the same H2L2 heterodimeric antibody structure seen in all jawed vertebrates (reviewed in Flajnik 2002). The constituent vertebrate immunoglobulin (Ig) heavy (H) and light (L) chains provide obligate defense against pathogens and their toxins via neutralization, opsonization, and activation of the classical pathway of the complemen...
