Prepubertal beef heifers at 60 and 200 d of age, born in the fall or spring, were assigned randomly to one of three treatment groups: (1) intact = 1; (2) bilateral ovariectomy (OVX); or (3) OVX plus estradiol-17 beta(E2) administered in silastic implants (OVX + E2). Luteinizing hormone (LH) was measured in serum samples collected at 20-min intervals for 4 h from heifers on -1, +7, +21, +35 and ...

49 he liberalization of the world’s energy markets is forcing the electric supply industry to reorganize itself from the ground up. On the one hand, it is expanding to include energy services, power marketing and information technology based services; and on the other, it is increasing asset utilization, reducing maintenance costs, and saving on investments by optimizing operation of the existi...

Geometric data summarization has become an essential tool in both geometric approximation algorithms and where geometry intersects with big data problems. In linear or near-linear time large data sets can be compressed into a summary, and then more intricate algorithms can be run on the summaries whose results approximate those of the full data set. Coresets and sketches are the two most import...

background: 49, xxxxy syndrome is a rare sex chromosomal disorder, occurring in 1 per 85,000-100,000 male births. the classical phenotype is ambiguous genitalia, facial dysmorphism, mental retardation and a combination of cardiac, skeletal and other malformations. case: a two month-old boy with intrauterine growth restriction (iugr) and low birth weight, facial dysmorphism, clinodactyly in feet...

Carboxylesterases (CES) are a well recognized, yet incompletely characterized family of proteins that catalyze neutral lipid hydrolysis. Some CES have well-defined roles in xenobiotic clearance, pharmacologic prodrug activation, and narcotic detoxification. In addition, emerging evidence suggests other CES may have roles in lipid metabolism. Humans have six CES genes, whereas mice have 20 Ces g...

Technical systems are subjected to a variety of excitations that cannot generally be described in deterministic ways. External disturbances like wind gusts or road roughness as well as uncertainties in system parameters can be described by random variables, with statistical parameters identified through measurements, for instance. For general systems the statistical characteristics such as the ...
