The efficacy of extended-release eprinomectin for the reduction of horn flies, face flies, and fecal egg counts of parasitic nematodes in replacement beef heifers

The purpose of this study was to evaluate the efficacy of extended-release eprinomectin against horn flies, face flies, and fecal egg counts of parasitic nematodes in crossbreed replacement beef heifers. Fifty-four heifers were randomly placed into three treatment groups (N=18 heifers/treatment). Group 1 was administered the labeled dosage of extended-release eprinomectin on day 0. Group 2 acted as the negative control. Group 3 received the anthelmintic injection once a quarter of the heifers in the group reached the threshold treatment level for horn flies (N=200 flies/animal; day 41). Nematode infections were measured via fecal egg counts while horn and face flies were visually monitored. Evaluation of pregnancy status was recorded at study conclusion (day 144). Due to the high number of face flies, heifers were treated with insecticide dusts twice during the study (day 54 and 69). Low egg counts for all treatment groups reflected minimal parasite burden. Extended-release eprinomectin had little influence on face flies given that all groups were above threshold at days 40, 48, and 54. At study conclusion, horn fly population was lower (P

What's the potential impact of casino tax increases on wagering handle: estimates of the price elasticity of demand for casino gaming.

This study estimates the price elasticity of demand for casino gaming. A demand model is estimated with data from a panel of 50 casinos operating in Illinois, Indiana, Iowa, and Missouri between 1991 and 2005. The model isolates the impact of changes in the casino win percentage or price on the wagering handle, controlling for the impact of other operating, economic, and regulatory determinants of the wagering handle. The model estimates suggest that the wagering handle in the short run is inelastic to price changes, and that in the long run the wagering handle is unit elastic if not somewhat inelastic.Casinos

Asymptotic expansions in the conditional central limit theorem

AbstractLet Xn, n∈N, be i.i.d. with mean 0, variance 1, and E(¦Xn¦r) < ∞ for some r ⩾ 3. Assume that Cramér's condition is fulfilled. We prove that the conditional probabilities P(1√n Σi = 1n Xi ⩽ t¦B) can be approximated by a modified Edgeworth expansion up to order o(1n(r − 2)2)), if the distances of the set B from the σ-fields σ(X1, …, Xn) are of order O(1n(r − 2)2)(lg n)β), where β < −(r − 2)2 for r∉N and β < −r2 for r∈N. An example shows that if we replace β < −(r − 2)2 by β = −(r − 2)2 for r∉N(β < −r2 by β = −r2 for r∈N) we can only obtain the approximation order O(1n(r − 2)2)) for r∉N(O(lg lgnn(r − 2)2)) for r∈N)

Soft and Hard Implant Fabrication Using 3D-Bioplotting TM

At the Freiburger Materialforschungszentrum we have developed a new process (3DBioplotting TM) that permits most kind of polymers and biopolymers to be used in 3D scaffold design, including hydrogels (e.g. collagen, agar), polymer melts (e.g. PLLA, PGA, PCl) and twocomponent systems (e.g. chitosan, fibrin). Cells can be incorporated within the construction process, making this an ideal Rapid Prototyping technique for Organ Printing. Tailor-made biodegradable soft or hard scaffolds can so be fabricated in a short time using individual computer-tomography data from the patient. In-vitro tests showed promising results and in-vivo experiments are now under observation.Mechanical Engineerin

Avoidable Hospitalizations

Georgia Health Policy Center worked to improve health care in eight of the most rural, medically under served states in the country. The Center conducted research and provided strategic planning for eight Southern states: Alabama, Arkansas, Georgia, Louisiana, Mississippi, South Carolina, East Texas and West Virginia

An Assessment of Health Care Safety Net Services in Seven Metropolitan Atlanta Counties

The Georgia Health Policy Center (GHPC), the Centers for Disease Control and Prevention (CDC) and the National Network of Public Health Institutes began collaboration in the summer of 2007 on a project designed to establish a framework for public health to help inform the health reform debate. The partnership set out to broaden the health reform conversation to include health promotion, health improvement, and disease prevention. The effort included background research, focus groups, key interviews with internal and external stakeholders from local, state, and national groups, and additional convenings of local, state, and national partners. This report highlights opportunities for public health to bridge the different levels of health reform and create strategies and policies that could be implemented on each level

Variable Powder Flow Rate Control in Laser Metal Deposition Processes

This paper proposes a novel technique, called Variable Powder Flow Rate Control (VPFRC), for the regulation of powder flow rate in laser metal deposition processes. The idea of VPFRC is to adjust the powder flow rate to maintain a uniform powder deposition per unit length even when disturbances occur (e.g., the motion system accelerates and decelerates). Dynamic models of the powder delivery system motor and the powder transport system (i.e., five–meter pipe, powder dispenser, and cladding head) are first constructed. A general tracking controller is then designed to track variable powder flow rate references. Since the powder flow rate at the nozzle exit cannot be directly measured, it is estimated using the powder transport system model. The input to this model is the DC motor rotation speed, which is estimated on–line using a Kalman filter. Experiments are conducted to examine the performance of the proposed control methodology. The experimental results demonstrate that VPFRC is successful in maintaining a uniform track morphology, even when the motion control system accelerates and decelerates.Mechanical Engineerin
