Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Angus x Simmental cows (n = 48, BW = 594 kg, BCS = 5.26, Age = 2.7), pregnant with male fetuses, were used to determine the effect selenium (Se) source during the last 80 d of gestation and first 108 d of lactation on progeny feedlot performance. At 203 d in gestation, cows were blocked by body weight, age, breed composition, and calf sire, and allotted to 1 of 3 treatments: no Se, inorganic Se, or organic Se. Maternal diets were formulated to contain 10.4% CP and 0.90 Mcal/kg NEg during gestation and 12.1% CP and 1.01 Mcal/kg NEg during lactation. Basal diets contained 0.07 and 0.11 mg/kg Se for gestation and lactation diets; respectively. Diets were fed daily as a total mixed ration and Se was provided in a top-dress containing 0, 0.30 mg/kg Se as sodium selenite, or 0.30 mg/kg Se as Sel-PlexRTM. Treatment diets were fed through 108 d post-partum (DPP). At 68 DPP milk production was calculated using the weigh-suckle-weigh procedure and a milk sample was collected was at 62 DPP to determine composition. At 108 DPP cow-calf pairs were commingled until weaning at 216 DPP. At 28 d post-weaning, steers (n = 47, BW = 301 kg) were placed in individual pens and fed a diet formulated to provide 13.9% CP, 1.24 Mcal/kg NEg, and 0.10 mg/kg Se. The diet was delivered as total mixed ration once daily. Cow weight and BCS and calf birth weight did not differ at the beginning of the trial (P ≥ 0.55). Cow BW and BCS (P ≥ 0.85) did not differ between treatments at any time point during the study. Milk production, milk fat, and total solids ( P ≥ 0.38) did not differ among treatments. Milk protein tended to increase in cows fed inorganic Se compared to cows fed organic Se ( P = 0.07) and milk lactose tended to be greatest in cows fed organic Se (P = 0.10). Conception to AI and overall pregnancy rates did not differ between the diets (P ≥ 0.39). Calf weights and ADG did not differ for the 105 d experimental period (P ≥ 0.77) or for the entire pre-weaning period (P ≥ 0.33). Plasma Se concentration did not differ between treatments for the cows ( P ≥ 0.37). Liver Se concentration in cows fed inorganic and organic Se treatment were significantly greater than that of cows from the control treatment (P

Book Synopsis Effects of Two Forms of Intrareticular Selenium Supplements on Beef Cow Selenium Status and on the Transfer of Selenium from Dam to Offspring by : Donald T. Campbell
Download or read book Effects of Two Forms of Intrareticular Selenium Supplements on Beef Cow Selenium Status and on the Transfer of Selenium from Dam to Offspring written by Donald T. Campbell and published by . This book was released on 1989 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two concurrent studies were conducted to evaluate the effect of selenium (Se) supplementation on beef cows. Trial 1 was designed to evaluate the safety and efficacy of two intrareticular Se supplementation delivery systems. Trial 2 was designed to evaluate the transfer of Se across the placenta and through the colostrum in beef cows. One hundred fifty, selenium (Se) deficient, pregnant crossbred beef cows were assigned to 1 of 4 treatment groups: group A, negative control; group B, 1 Dura-Se bolus at 0 and 119 d; group C, 1 Dura-se at 0 d; and group D, 2 Permasel pellets at 0 d. Cattle were maintained on selenium deficient pastures or forages prepared from these pastures. Blood samples were collected from cows before treatment administration (0 time) and thereafter at 28, 52, 119, and 220 d. Calves from cows selected for data collection above were sampled at birth. Blood samples were collected from calves, prior to suckling, and were analyzed for whole blood selenium (WBSe) concentration. Colostrum samples were collected from dams and analyzed for total Se concentration. Additional samples were collected from calves 24-48 hours post suckling and analyzed for WBSe concentration and serum creatine kinase (CK) level. Weight and health data were recorded on all cows at each blood collection date. Birth weight, sex, and health were recorded on all calves at parturition. Whole blood selenium concentration of cows from all supplemented groups were significantly higher (P.001) than controls at all sample dates after treatments began. By the end of the 220 d study, treatment group B attained significantly higher (P.001) WBSe concentrations than any other group. Calves from all Se treated groups had significantly (P.001) higher WBSe concentrations, both pre- and post-suckling, than controls. Post-suckle WBSe concentration of calves were not significantly (P.05) different than pre-suckle concentrations in any of the groups. Colostrum selenium concentration from Se supplemented cows were significantly (P.001) higher than from control cows. No difference (P.05) was determined in plasma CK activities or birth weights between groups of calves. Seven animals died, two of which showed signs of Se deficiency. Necropsy of 5 calves provided no evidence linking these deaths to selenium treatments. No differences (P.05) in mortality between groups were determined.

Book Synopsis Selenium Contamination in Water by : Pooja Devi
Download or read book Selenium Contamination in Water written by Pooja Devi and published by John Wiley & Sons. This book was released on 2021-05-12 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 μg per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium’s origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.
