the grace mission has provided scientific community time-variable gravity field solutions with high precision and on a global scale. the grace mission was launched on march 2003. this mission consists of two satellites that pursue each other in their orbit. distance between two satellites in orbit is measured continuously to an accuracy of better than 1 micron using kbr system placed in satelli...

A new species of Phrixosoma from Tanzania is described and illustrated. This is a unique species for the genus in having a strongly concave female frons. Several characters are described for the first time for this genus, including male and female genitalia, mouthparts, thoracic sutures, and several overlooked features of the mesoand metatibiae and sternal processes.

Beginning with the Pronto4TM Strap-on Autonomy System — a retrofit kit that makes any existing vehicle with a steering wheel a drive-by-wire system — and including a flexible, shared variable software base running on an open architecture system, DesignJug is enhancing its technology by creating a new sensor platform with supporting software that provides input to the team’s Actively Refined Rea...

The role of Epithelial Na Channel (ENaC) proteins in cardiovascular regulation and blood pressure control traditionally have been viewed through the lens of ENaCdependent salt and water transport in the renal cortical collecting duct. In this nephron segment, decreases in ENaC expression/activity lead to salt and water wasting resulting in hypotension and increases lead to hypertension via incr...

ticular regard to the incorporation of the glucosaminyl 3 0 sulphate marker group. A capsular polysaccharide derived from Escherichia coli K5, having the same [-GlcA-GlcNAc-I,, structure as the initial polymerization product in heparin biosynthesis, was chemically N-deacetylated and N-sulphated and used as a substrate for detergent-solubilized mastocytoma microsomal enzymes, in the presence of ...
