Book Description
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 1957, 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 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 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 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
Livestock grazing endophyte-infected tall fescue can have decreased performance due to vasoconstriction and reduced reproductive performance. Therefore, the objective of this study was to determine the effect of supplementing rumen-protected arginine to cows consuming endophyte-infected tall fescue seed on caudal blood flow and LH dynamics. Four ruminally cannulated, open beef cows (539 ± 30 kg) were used in a 2 x 2 factorial arrangement of treatments utilizing a Latin Square design with 4 periods of 31 d each. Each cow was assigned to individual pens and fed orchardgrass hay (10.3% CP and 85% NDF; OM basis) during a 10-d adaptation period, followed by a 21-d collection period in which each cow was assigned one of 4 treatments: (1) rumen-protected ARG (180 mg/kg of BW) and 1.0 kg/d of endophyte-infected fescue seed (AE+); (2) rumen-protected ARG (180 mg/kg of BW) and 1.0 kg/d of non-infected fescue seed (AE-); (3) 1.0 kg/d of endophyte-infected fescue seed (E+) alone; or (4) 1.0 kg/d of non-infected fescue seed (E-) alone. In each period, doppler ultrasound measurements for blood flow parameters were quantified on d 1, 5, 10, 15, and 19. On d 20 of each period, blood samples were collected every 10 min for 6 h and then once every hour for 12 h. Caudal blood flow exhibited an interaction (P = 0.05) of ARG × fescue seed type, resulting from an increase in blood flow in cows fed rumen-protected ARG. In addition, mean velocity was greater (P = 0.01) with the inclusion of rumen-protected ARG in the diet. Caudal artery area (P = 0.03) and diameter (P = 0.01) were decreased in cows consuming E+ compared to E- with no effect (P ≥ 0.38) by ARG supplementation. Mean serum LH concentration exhibited (P = 0.02) an ARG × fescue seed type interaction. Cows consuming E+ had decreased LH concentrations compared to all other treatments. However, cows consuming AE+ had similar LH concentrations compared to cows consuming AE- or E-. Thus, supplementing rumen-protected ARG to cows grazing endophyte-infected fescue seed has the potential to increase reproductive performance and peripheral blood flow.
