Tissue Ammonium Nitrogen In Sheep Tongue, Liver And Kidney Following Death By Ammonia Intoxication, Dale L. Jaquette Mar 1972

Tissue Ammonium Nitrogen In Sheep Tongue, Liver And Kidney Following Death By Ammonia Intoxication, Dale L. Jaquette

Electronic Theses and Dissertations

Urea was introduced as an economical nonprotein nitrogen source for ruminant animals. In the gastrointestinal tract, urea is hydrolyzed in the presence of bacterial urease to ammonia and carbon dioxide. The liberated ammonia is utilized by rumen microorganisms for amino acid synthesis. Ammonia not used by microorganisms diffuses through the gastrointestinal lining and is transported to the liver by blood, where enzymes synthesize urea by combining two moles of ammonia and one mole of carbon dioxide. The nontoxic urea is excreted by the kidney or secreted with saliva and other digestive fluids for recycling. Ammonia intoxication occurs when more ammonia …

Sulfur And Methionine Supplementation With Urea For Feedlot Cattle, Bryan E. Davidson Mar 1972

Sulfur And Methionine Supplementation With Urea For Feedlot Cattle, Bryan E. Davidson

Electronic Theses and Dissertations

Protein is often a limiting nutrient in animal diets. As ruminant animals have the ability to convert large quantities of nonprotein nitrogen to protein, the cost of protein supplementation can be greatly reduced by substituting cheaper nonprotein nitrogen compounds in protein supplements for certain amounts of preformed protein. This process is mediated through rumen microorganisms and, to date, urea has been the most widely used nonprotein nitrogen compound in ruminant diets. Efficiency of urea utilization may be affected by several factors. Among these are level and source of energy, level and source of protein and percent urea in the total …

Operation Of Induction Motor Open-Delta Transformer Banks, Gautam C. Das

Electronic Theses and Dissertations

Induction motors and transformers are among the earliest electrical equipment to be manufactured. The squirrel-cage induction motor has been studied very widely from the time of Tesla and Ferraris in 1889. The operation of a squirrel-cage induction motor with an unbalanced supply voltage has also been studied in great detail. Yet there is little mention of an induction motor operating on an open-delta or vee-connected transformer bank in textbooks. The open-delta transformer connection is the equivalent of the delta-delta connection with one transformer removed. The vee-connection is equivalent to a star-delta connection with one transformer removed; the primary neutral must …

Parameters Of The Super-Beta Transistor, Ho-An Au Feb 1972

Parameters Of The Super-Beta Transistor, Ho-An Au

Electronic Theses and Dissertations

Transistors with current gains of 1,000 to 10,000 at collector current levels as low as 1 µA can now be made in discrete and in monolithic form. These devices are generally called super-beta or super-gain transistors. It is well-known that a narrow base width results in a high-beta transistor. As the emitter is diffused more deeply into the base, reducing the base width, the current gain will increase. But there is a trade-off between breakdown voltage and current gain. When the emitter is deeply diffused, the depletion region of the collector-base junction may penetrate the base and reach through to …
