Wayne E. Sabbe Arkansas Soil Fertility Studies 2017

Rapid technological changes in crop management and production require that the research efforts be presented in an expeditious manner. The contributions of soil fertility and fertilizers are major production factors in all Arkansas crops. The studies described within will allow producers to compare their practices with the university’s research efforts. Additionally, soil-test data and fertilizer sales are presented to allow comparisons among years, crops, and other areas within Arkansas

Keys to Optimizing Profitability in Cow-Calf Production -- Rooster\u27s Beef, 3 Generations of Farming & Beef

Rooster\u27s Beef ultimately began with our family farm -Rocky Bluff Farm - now owned by William and Becky Slaton. It is the cattle producer for our beef sold. The farm is named after two Natural Rock Formations on our property. We have several acres of pasture and including some wooded acres. With rotational grazing and intense management, we are able to have 65 cows in a spring calving group, 15 cows in a fall calving group, 3 bulls, 13 replacement heifers, unweaned calves and 12 calves on finisher feed. We also rent ground to raise and put up our own hay

Lavish travel by cabinet members on the public's dime shows the emptiness of Trump's promise to "drain the swamp"

At the end of September, Secretary of Health and Human Services, Tom Price, resigned following controversy over his use of private and government jets at taxpayer expense. Christa Slaton writes that Price and other Trump Cabinet officials' use of private and government flights is a symptom of an administration - and a president - that is staffed by officials that ..

Thermal Insulation Coating for Pipe Applications

NNSB tasked the Capstone team with testing the anti-condensation abilities of the Thermal Insulation Coating (TIC) Aerolon®, an aerogel-based insulation manufactured by Tnemec, using Federal test specifications for Coating Compound, Paint Antisweat. The main goal was to observe the anti-condensation abilities of the insulation and to initiate an analysis and comparison of the spray-applied aerogel insulation versus the hand-applied thick foam insulation that is currently used on ship pipes and ventilation. The plan includes creating a computer simulation of the thermal properties of the insulated cylinders as well as a physical experimental setup. The Capstone team built an acrylic test chamber, and NNSB provided three copper cylinders that were coated in 3 different thicknesses of Aerolon®. The federal specification called for these 3 cylinders to be filled with ice cubes and water and maintained between 32°F and 38°F for the duration of a 3-8 hour test period. The specification also calls for the interior of the acrylic chamber to maintain at a relative humidity of 67% ± 2. Due to the difficulty maintaining the humidity of the chamber without expensive equipment, the humidity was not controlled, but the dew point was calculated. The physical testing right away showed that, even in a cool chamber with a relatively low humidity, the 50mils thick insulation layer allowed for condensation, without any drip. The 100mils and 150 mils thick insulation layers did not allow any condensation for the temperature and humidity tested. It is anticipated that with increased chamber temperature and humidity, all three insulated cylinders will show condensation and possible water runoff. In addition to physical testing, a computer simulation of the insulated cylinders was created. The simulation allows for observation of the heat distribution inside the different thicknesses of the coating, which could assist in an initial estimate of the thickness of insulation needed for different applications. Despite timeline differences that set the project back further than expected and financial limitations that prevented the level of control desired in physical testing, Tim Sherrange has proposed to NNSB that the project be continued. The further testing done during this extension could better define the condensation levels and water runoff that each thickness of insulation would allow. At this time the proposal has not been confirmed.https://scholarscompass.vcu.edu/capstone/1213/thumbnail.jp

Comparing Different Scaling Methods for Monitoring Weightlifting Performance

Physiological performance has been commonly scaled for body size using various methods to scale anthropometrics, but a paucity of data exists on scaling muscle size. The aim of this thesis was to elucidate the optimal method to scale height (HT), body mass (BM), lean body mass (LBM), and muscle cross-sectional area (CSA) when scaling weightlifting performance for body size. 26 weightlifters (13 male, 13 female) participated in this study. The measurements collected were the snatch (SN), clean and jerk (CJ), isometric peak force (IPF), and countermovement jump height (CMJH). HT, LBM, BM, and vastus lateralis CSA were scaled using the ratio standard and allometry. Competition performance scaled for allometrically scaled CSA possessed greater relationships to CMJH (r = 0.60 – 0.78) than the ratio standard (r = 0.56 – 0.58). These findings suggest that allometrically scaling CSA may be superior when scaling weightlifting performance for CSA
