Recently, radial velocities have been measured for a large sample of M giants from the 2MASS catalog, selected to be part of the Sgr dwarf leading and trailing streams. Here we present a comparison of their kinematics to models of the Sgr dwarf debris orbiting Galactic potentials, with halo components of varying degrees of flattening and elongation. This comparison shows that the portion of the...

Intended to provide long-term control of Medicare physician spending, the Sustainable Growth Rate (SGR) tied certain Medicare Part B payments to the economic performance of the United States. Although sensible in concept, the political implementation of the SGR resulted in a failed and perilous policy that challenged sensibilities and practice since its implementation in 1997. Few professions o...

In this study, Artemia parthenogenetica was fed with either Spirulina (S), yeast (Y), rice bran (R), oat (O) or their combinations in 10 experimental groups triplicate for 20 days laboratory conditions and growth, biomass, feed conversion rate (FCR), specific growth (SGR), survival rate, crude protein, lipid contents were determined. The highest average body length obtained at the end of experi...

The accumulation of ammonia, a consequence intensive aquaculture activity, can damage cultured animals. We analyzed the survival rates, growth, antioxidant responses, and immune responses abalones, Haliotis discus hannai (mean shell length 70.2 ± 4.9 mm; mean body weight 36.9 3.6 g), biweekly for four weeks, to determine accumulated concentrations ammonia (0, 0.1, 0.2, 0.4, 0.8, 1.6 mg/L). In o...

Escherichia coli O157:H7 can contaminate raw ground beef and cause serious human foodborne illness. Previous reports describe the behavior of E. coli O157:H7 in ground beef under different storage conditions; however, models are lacking for the pathogen’s behavior in raw ground beef stored over a broad range of temperature. Using sterile irradiated raw ground beef, the behavioral kinetics of 10...

The aim of this study was to evaluate the influence of stocking density (0.5, 1, 2 and 3 fishL(-1)) and commercial marine fish diets (diet A, B, C and D) over four months on specific growth rate, condition factor, percentage without anomalous pigmentation (partial or total lack of white bands -miss-band) and survival of juvenile Amphiprion percula. Results showed that at 0.5 fishL(-1) densities...

The effects of oral administration of different doses of estradiol-17 (E2) were examined on the growth performance, body composition, sex steroids, blood indices and histology of liver and gonad in Acipenser stellatus juveniles. Five-months-old fish (40.9 ± 1.1 g) were fed 0, 25 and 50 mg E2 kg diet for 210 1 days. Results showed that increasing doses of E2 caused reduce growth rate. No signifi...

the aim of this study was to show the effect of four feeding regimes on thyroid hormones concentrations, growth performance and food coefficient in rainbow trout applied through 4 treatments and 3 replications in winter 2006. in this research, samples of rainbow trout with an initial mean weight (so) 47.19±0.42 used in each rearing unite. fish were fed twice a day ad libitum as follows: treatme...
