The net release of insulin, glucagon and somatostatin by the portal-drained viscera (PDV) and their net uptake by the liver in response to 3-d abomasal infusions of casein were measured in seven multicatheterized beef steers. The steers were fed 4.3 kg DM/d of a high-concentrate diet in 12 equal meals (13.1 Mcal ME/d and 95 g N/d). In two separate experiments, the abomasal infusion of 300 g cas...

Amorphous hydrogenated carbon films were prepared by hot filament Plasma Enhanced Chemical Vapor Deposition using acetylene as precursor. NiP-coated Al substrate was sputtered with thin layer of ruthenium film prior to carbon deposition for its impact on carbon film growth. Film thickness measured and fitted using X-ray Reflectometry showed carbon film growth is an exothermic reaction with appa...

Tracers are needed for the development of high-temperature geothermal resources. Several candidate tracers have been tested for that purpose in hydrothermal autoclaves at the Energy & Geoscience Institute in Salt Lake City, Utah. One gas tracer, SF6, and two of the two-phase tracers, the straightchain alcohols, were tested. They were tested at temperatures ranging from 220 to greater than 300C,...

The effect of flux angle, substrate temperature and deposition rate on obliquely deposited germanium (Ge) films has been investigated. By carrying out deposition with the vapor flux inclined at 87 to the substrate normal at substrate temperatures of 250C or 300C, it may be possible to obtain isolated Ge nanowires. The Ge nanowires are crystalline as shown by Raman Spectroscopy.

Thus, we started a...
