Most amphiphiles in biological membranes including phospholipids, steroids, and membrane
proteins are insoluble amphiphiles and would form liquid crystals or insoluble precipitates …

The requirement for molybdenum in biological dinitrogen fixation, first reported by Bortels 1 ,
is due to its involvement at or near the site of reduction of N 2 in conventional nitrogenase. …

Calculations of the size, shape, and hydration of micelles composed of the nonionic surfactant
Triton X-100 were performed based on molecular weight and intrinsic viscosity data. …

Understanding of biological nitrogen fixation, an exclusively microbiologiн cal process, has
developed almost explosively in the last two decades. The appearance of numerous books, …

There continues to be widespread interest in the applications of hydrogen as a clean fuel and
its potential for local electricity production and use in transport. Recent years have seen a …

The kinetic theory of charged test particles in a neutral gas, in the presence of static and
uniform electric and magnetic fields, is reviewed. The effects of inelastic processes and …

1. Nitrogenase activity of a strain of Azotobacter chroococcum lacking the structural genes
for conventional nitrogenase (nifHDK) was separated into two components: an Fe-containing …

A representation of the hierarchy of kinetic equations formulated earlier [Phys. Rev. A 33,
2068 (1986)] for reacting charged-particle swarms in gases is obtained in the Sonine …

The'two-term'approximation (representation of the electron distribution by the first two terms
of an expansion in spherical harmonics in velocity space) continues to occupy a central role …

The kinetic theory of charged particles in gases has come a long way in the last 60 years or
so, but many of the advances have yet to find their way into contemporary studies of low-…
