Selecting for Carcass Merit

Today\u27s consumers are asking for leaner, less-fatty beef. Much of the leaner beef now produced results from trimming excess fat before the product is sent to the consumer. For the future, the hope is to trim excess fat genetically by producing leaner, more heavily muscled beef cattle

Effects of Fertilizers on Cultured Salt Marsh Plants, Ruppia and Chara

Widgeongrass (Ruppia maritima), muskgrass (Chara Sp.), and midge larvae (family Chironomidae) were grown under controlled greenhouse conditions using a solution of Logan tap water, 3000 ppm. sodium chloride, and an algicide-fungicide inhibiter. Soil, vegetation, and invertebrates came from a spring-fed marsh in western Utah. Ammonium sulfate, treble superphosphate, and sewage sludge fertilizers were applied to the plants at 5, 10, 20, 25, 50, 75, 100, and 300 pounds per acre equivalents of ammonium sulfate; 5, 25, 50, 75, 100, and 300 pounds per acre equivalents of treble superphsophate; and 5, 25, 100, 200, 300, 400, 500,700, and 1000 pounds per acre equivalents of sewage sludge. Widgeongrass plants had weights below the control at all fertilizer levels. Plant lengths at treatment levels of 10 pounds per acre equivalents ammonium sulfate and 5 pounds per acre equivalents sewage sludge were greater than the control length, but the differences were not significant. Muskgrass plants had weights which were neither significantly above or below the control weight. Muskgrass plants at the 75 pounds per acre rate of treble superphosphate had significantly greater lengths than did the control. The highest chironom.id survival rate, 12. 6 percent, occurred in the control treatm.ent. B1uegreen algae, Oscilatoria sp., was present in all fertilized treatments

The Use of Metacognitive Verbs by a Student with ASD: Marking Perspective in Conversational Discourse During Narrative Intervention

The purpose of this study was to assess whether a program designed to teach narrative language skills was effective for improving the use of metacognitive verbs produced during conversations that took place during intervention to mark perspective

Growth Stimulants and Feed Additives

In recent years, the most revolutionary increases in beef cattle weights and feeding efficiencies have resulted from the development and use of growth stimulants, feed additives, and antibiotics. These nonnutritive products not only improve the rate and efficiency of gain but prevent certain diseases as well. Their use has significantly improved beef cattle production efficiency and provided a greater return per dollar invested than any other factor in the livestock industry. Growth stimulants deposit increased protein in the animal without changing protein or energy intake. They are designed to provide a constant slow release of active ingredients into the animal\u27s bloodstream. In animals implanted with growth stimulants, the blood levels of hormone will fluctuate according to physiological factors associated with digestion and absorption of nutrients in the feed. The nutritional state of the animal and the quality and quantity of feed consumed will also determine the effectiveness of the growth stimulants

Integrated system-level design in electrical engineering

Journal ArticleThis paper describes an NSF-sponsored department level curriculum reform project in the Electrical and Computer Engineering Department at the University of Utah. The project focuses on developing system-level design projects (mostly labs, but a few software-only projects) that integrate ideas within a class, between classes, and in some cases between disciplines. Written and oral communication is also stressed throughout this program. Materials are available for use by other educators via the PI (Furse) or the website

Selection and Development of Replacement Beef Heifers

Selection, development, management, and nutrition of heifer calves to be used as herd replacements are key factors in maintaining beef herd productivity. A cow/calf producer, to be successful, must have some goals or criterion for heifer selection and development. For practically all Utah cattle production areas, economics dictate that heifers must calve as two-year-olds. Heifers must be properly developed and managed to permit this. The following factors are important: Heifers should 1) become pregnant in the first 25 days of the breeding season, 2) give birth to a live calf with little or no calving difficulty, 3) raise a calf to weaning that has an average or above weaning weight, 4) breed back as a two-year-old in the first 45 days of the breeding season, and 5) continue to reproduce and wean a calf each year until 9 or 10 years of age

Larmhantering i processindustrin

The objective of this thesis is to reduce the alarms in the control rooms of the processing industry and to investigate a strategy for working with the alarms. The problem with the alarms in the automation system is a result of the highly automated production and failure to design the alarms for the operator. The situation analysis showed problems with badly tuned alarms and cascade of alarms. The badly tuned alarms result in alarms triggers without any danger for the process or personal, it also results in silent alarms never signaling although the risk for failure is high. The cascades of alarms occur when one fault triggers many alarms due to the correlation of process parameters. From the situation analysis was concluded that a structured work with alarms and forming groups addressing the problems would be the best way to reduce troubles with alarms. To structure the work with alarms a document with guidelines were created. This document includes the personnel of the alarm group and their tasks. It also describes the definition of an alarm which is a signal sent to the operator showing that the process doesn't behave as it should and the system therefore call for the operators' attention to act. A part of the alarm document also describes how to organize the information about the alarm points. The alarm points were documented by extracting data from the automation system to Excel and formatted by VB-script. To make it easy to update the information the script can automatically compare the data in the automation system with the data stored in documentation. The personnel will add information about the intention of the alarm and the measure to take when the alarm is signaling. The user added information is to justify the alarm. A pilot project with forming an alarm group documenting and structuring the alarms was conducted. Results are promising and show the working with alarms really can cut the alarm frequency and improve the working environment for the operator
