EVALUATION OF ERAGROSTIS TEF AS A FORAGE OPTION FOR GRAZING BEEF CATTLE ON THE SOUTHERN HIGH PLAINS
(2019-04-19)Teff grass (Eragrostis tef [Zucc.] Trotter) was fed to beef steers either alone or in combination with crude protein supplements in order to evaluate forage DMI, animal growth performance, grass production attributes, water ... -
Cascaded H bridge based solid state transformer for Medium Voltage and Low voltage interface, Simulation and Analysis.
(2019-05-02)This thesis paper presents a smart way to interface a medium voltage grid with low voltage grid as a response to rapidly growing penetration of distributed Energy resources (DES) in the power system grid. With renewable ... -
Determination of Several Elements in Chelonia mydas and Pterodroma hypoleuca from Hawaii
(2019-04-25)Elemental contaminants are present in the food chain through natural or anthropogenic sources. Larger doses, longer durations of exposure and frequent exposure will increase the risk of elemental toxicity. Animals such as ... -
Analyses of national and local data to determine associations in separate child and adult samples: Examining predictors of stunting among 24 to 59 month old children in Bangladesh and interrogating associations of weight history and attempts to lose/manage weight in West Texas, USA
(2019-04-26)Background: Stunting is a major public health problem in Bangladesh. The persistent prevalence of stunting in Bangladesh remains virtually unchanged, and the rate of reduction is even lower than in the past. Most notably, ... -
