Cryogenic liquid level measuring probe

Universal probe, which contains a unique frequency discriminator, measures the static and dynamic levels of cryogenic liquids in a hydrogen bubble chamber. The probe allows boiling conditions or other turbulence to be observed throughout all the transition stages

Circular 35

Revised April 1991 by Grant E.M. Matheke, Patricia J. Wagner, and Patricia S. Holloway; Reprinted by Cooperative Extension Service, University of Alaska Fairbanks, and U.S.D.A. Cooperating. Publication 300C-00235A technique for growing high-yielding, everbearing strawberries with clear polyethylene (plastic) mulch and row covers has been developed at the Agricultural and Forestry Experiment Station at Fairbanks. This technique eliminates the long delay from planting to fruiting that occurs with other culture systems and it has created an interest in commercial production and an increased home-garden effort in Alaska. The production system involves planting nursery plants each season as early as possible through clear polyethylene mulch, using row covers for the early part o f the season. Using this technique, harvest begins about July 15 and extends until freeze-up, com pared to a production season from about July 10 to July 28 for hardy types o f strawberries such as Toklat or Pioneer. This system produces clean fruit, easy to pick and relatively free from fruit rot. The harvest season can be extended in the fall by again using the row covers for frost protection

Indexing Beef Cattle

The primary purpose of this circular is to furnish some simplifications in the procedure presently in use in South Dakota for indexing beef cattle. As more data become available, t h e s e methods may change and in that event, supplements will be distributed. Such differences as exist between the shortcut methods presented here and those presently in use will be pointed out as they are taken up in the circular. The methods presented here are based on data taken in private herds in the state as well as in Experiment Station herds. Where there appeared to be a difference, data from private herds were used so that the results would be more widely applicable. This publication is not intended to replace the present Extension Service circular dealing with methods and procedures of performance testing. For details concerning methods, the reader should consult the circular available through the Extension Service

Agricultural Research at the Reed Ranch Substation: A Progress Report

Reed Ranch is located in Lyman County about midway between Pierre and Presho. It consists of 2,160 acres used for grazing and hay production. This ranch has been used for nearly 20 years as a field laboratory for selenium research. On November 16, 1936, an agreement between the South Dakota State College Agricultural Experiment Station and the South Central South Dakota Land Adjustment Project of the Resettlement Administration outlined a program of cooperative research dealing with selenium poisoning. The program was initiated during 1937 and has continued since. As governmental organization has changed over the intervening years, the cooperating agency representing the Federal Government has also changed from time to time. The present cooperating agency is the U. S. Forest Service. The agreement now in effect covers the period from 1954 to 1964, and renewal beyond that period is anticipated. The present long-range policy has permitted the Experiment Station to make much needed physical improvements that have made the work at Reed Ranch easier and more efficient since 1953. The facilities for handling cattle have been rebuilt, living facilities modernized, and some additional fencing has been done. A shelterbelt has been planted north of the farmstead and 80 acres of native hayland are being replanted to alfalfa. The purpose of this publication is to acquaint citizens of South Dakota with research at Reed Ranch. It summarizes past and present experimentation and outlines plans for the future. This ranch is unique as a substation in that it was provided and is maintained to obtain information concerning chronic selenium poisoning or “alkali disease” in range cattle

Predicting Beef Palatability

The search for factors influencing the palatability of beef continues. The relative importance of variables in the USDA quality grading system that currently predicts acceptability and palatability has been questioned. The effect of marbling on palatability is one of the more controversial aspects. Marbling is one of the prime factors in determining the quality grade of a beef carcass and researchers have shown that other variables may play an equal or more important role influencing the eating quality of beef. The purpose of this study was to evaluate the accuracy of commonly-used predictors of palatability and to consider the possible influence of other carcass measures as predictors of palatability. Palatability, as defined in this study, was measured by the subjective taste panel scores for flavor, juiciness and tenderness. Tenderness mas measured objectively with the Warner-Bratzler shear instrument

Alumni Collegiate Student-Athletes’ Wellness After Sport

College student-athletes (may be more likely to experience difficulty transitioning from college than non-athletes, which could lead to decreased levels of overall wellness. Purpose: The purpose of this study was to explore the wellness of alumni SA who recently transitioned from college. Methods: Semi-structured interviews with former SA (n=12) were administered at a university in the Midwest. Interview questions were based on the Indivisible Self Model’s five factors of wellness (coping, social, physical, creative, and essential). Data were analyzed using the process of immersion/crystallization. Results: Results indicate that subjects generally experienced negative feelings at the end of their athletic career, but were able to overcome any struggles they experienced. Subjects mostly displayed high levels of wellness, especially in the creative, essential, and physical factors of wellness. Conclusion: Alumni SA that participated in this study displayed high levels of wellness. These findings: 1) illustrate the unique challenges in transitioning from college for alumni SA, and 2) inform prevention and intervention strategies for alumni SA struggling to transition from college

A Qualitative Exploration of Former College Student-Athletes’ Wellness

College student-athletes (SAs) may experience difficulties while transitioning from college, which could reduce their overall wellness. However, it is essential to understand positive transition experiences and outcomes, as this can guide future research and intervention efforts. The purpose of this study was to explore the factors that led to higher levels of wellness in former SAs. Semi-structured interviews guided by the Indivisible Self Model were completed with former SAs (n = 12). Overall, participants displayed high levels of wellness - most prominently in terms of work and exercise. Many SAs perceived their current wellness was equal, if not better compared to when they were SAs. These results illustrate examples of successful transitions of former SAs, which can guide future research and interventions
