Evaluation of Level of Milk Potential on Nutrient Balance in 2- and 4- Year- Old May- Calving Range Cows Grazing Sandhills Upland Range

A modeling study evaluated the effects of milk production level on nutrient balance in May- calving cows grazing Sandhills upland range during the breeding season. Forage quality of upland range peaks in June and steadily declines in July until November. With timing of forage quality decline and increasing nutrient demands due to lactation, cows were in a negative energy balance in late June and early July prior to deficiency of metabolizable protein. Supplementation to meet energy deficiencies in June and July and MP deficiencies in July with distiller grains that is high ruminally undegradable protein and high fiber energy may be needed in May- calving cowherds. Selection for milk over 23 lb at peak lactation creates deficiencies early post- calving and increases the need for additional supplementation to correct the nutrient deficiency. In an effort to match cow type to environment in the Sandhills and optimize performance, producers should consider selecting against high milk potential

Interface Of Glass And Topology

Interface of Glass and Topology is a supportive statement for a collection of blown glass sculptures that employ principles of continuous surface topology along with line and color applications to create a perceptual visual experience. These forms address issues of balance and continuity as well as space relationships of both inside to outside and object to self. This supportive statement will discuss topology as a basis for composition and larger questions of interconnectivity with our environment that serves as a guiding theme of my work

Experimental demonstration of stimulated polarization wave in a chain of nuclear spins

A stimulated wave of polarization, which implements a simple mechanism of quantum amplification, is experimentally demonstrated in a chain of four J-coupled nuclear spins, irradiated by a weak radio-frequency transverse field. The "quantum domino" dynamics, a wave of flipped spins triggered by a flip of the first spin, has been observed in fully $^{13}$C-labeled sodium butyrate.Comment: 8 pages including 3 figure

Dynamic Testing Procedures for Performance Assessment of Nuclear Fuel Rods

Existing transportation probabilistic risk assessment for spent nuclear fuel in the United States is based on short-term (decades) on-site storage at power plants before transport. Updated risk assessment estimates will be required as extended on-site storage (centuries) and higher burnup levels in fuel become standard. Nuclear fuel rods under these two conditions are more brittle than rods from short-term storage and intermediate burnup due to several mechanisms, including hydrogen embrittlement. Development of risk assessment requires characterizations of dynamic behavior of these degraded rods under transportation scenarios. This Honors thesis provides an initial literature review for a larger project that will investigate the dynamic response of fuel rods under vibration due to normal transportation only. The literature review covers testing procedures, methods for modeling pellet-cladding interaction, and methods for inducing hydrogen embrittlement in sample fuel rod specimens. Moreover, recommendations are provided for testing procedures for a rod sample on the uniaxial shake table at the University of New Hampshire. Recommendations include the use of acceleration data from truck transportation studies by Magnuson (1977 and 1978) modified to serve as appropriate shake table input. Another recommendation is the construction and use of a specialized “U-frame” for reversal bending fatigue tests on a segment of the sample rod, similar to work done by Wang et al. (2013) at Oak Ridge National Laboratory. The necessities of more transport acceleration data, a greater quantity of sample specimens, and in-depth study of flexural stiffness due to pellet-cladding interaction are outlined in the description of future work

Household demand persistence for child micronutrient supplementation.

Addressing early-life micronutrient deficiencies can improve short- and long-term outcomes. In most contexts, private supply chains will be key to effective and efficient preventative supplementation. With established vendors, we conducted a 60-week market trial for a food-based micronutrient supplement in rural Burkina Faso with randomized price and non-price treatments. Repeat purchases - critical for effective supplementation - are extremely price sensitive. Loyalty cards boost demand more than price discounts, particularly in non-poor households where the father is the cardholder. A small minority of households achieved sufficient supplementation for their children through purely retail distribution, suggesting the need for more creative public-private delivery platforms informed by insights into household demand persistence and heterogeneity

Evaluation of Lactation Demands on Nutrient Balance in Two Calving Seasons in Range Cows Grazing Sandhills Upland Range

A modeling study evaluated the effects of milk production level on nutrient balance in March-and May-calving cows grazing Sandhills upland range during the breeding season. Forage quality of upland range peaks in June and steadily declines in July until November. In March-calving cows, metabolizable protein (MP) and energy were deficient by July 1 in all milking potential cows, which is exacerbated in greater milking potential cows. May-calving cows with 20 to 30 lbs of milk are predicted to enter the breeding season with a deficiency in MP and energy. In an effort to match cow type to environment in the Sandhills, producers should be selecting against high milk potential. With timing of forage quality decline and the start of breeding season in July, selecting for moderation in milk production becomes even more important in May-calving herds. Supplementation to meet MP deficiency with high ruminally undegradable protein supplements may be need in later breeding cows and younger cows in both March-and May-herds

Integrating Economic Analysis with a Randomized Controlled Trial: Willingness-to-Pay for a New Maternal Nutrient Supplement

Maternal nutrition during pregnancy can have significant implications for a child’s prenatal growth and development, and undernutrition experienced during the prenatal period increases the risk of early childhood morbidity and mortality and can permanently impair a child’s physical growth and cognitive development. We use new data from Ghana generated using contingent valuation and experimental auction techniques to estimate willingness-to-pay (WTP) for LNS, a new nutrient supplement aimed at preventing maternal undernutrition during pregnancy. We also explore the relative importance of individual and household characteristics as well as information about the long-term benefits of preventing undernutrition on WTP. We find that WTP is positive for a large majority of individuals in our samples, and the level of WTP varies significantly with individual and household characteristics including gender, household food insecurity, and household expenditures. These findings suggest important policy implications for the development of delivery options and pricing mechanisms for LNS.Economic Development, Nutrition, Willingness-to-Pay, Food Consumption/Nutrition/Food Safety, Health Economics and Policy, International Development,

Exploring the Impact of Coaches’ Emotional Abuse on Intercollegiate Student-Athletes’ Experiences

Despite widespread anecdotal accounts of coaches’ emotional abuse in intercollegiate sports, empirical literature is lacking. To address this gap, the present exploratory study was designed to explore how former intercollegiate student-athletes interpreted experiences of emotionally abusive coaching. Former female NCAA and NJCAA student-athletes (N = 14; Mage = 25.3 years) took part in semi-structured, in-depth interviews. Data were interpreted using a constructivist grounded theory approach. The final product of the research was a three-stage grounded theory explaining how former student-athletes interpret their experiences of emotional abuse over time organized into sections on antecedents to abuse, experiences and actions within the abusive program, and after the abuse. Implications for this work include the idea that individual student-athletes may have different experiences and recollections of coaches’ emotionally abusive behavior and that intercollegiate student-athletes are able to discern between “hard, but fair” coaching practices and emotionally abusive coaching practices
