A Study of the Retention of Five Selected Mathematical Concepts of Seventh Graders in the Coulee Dam Public School System as Based on the Inductive and Deductive Methods of Teaching

The inductive and deductive methods of teaching for retention were compared in this study. It was also the purpose to determine whether there were significant sex differences in retention when the two methods were compared. Therefore, five hypotheses were tested

Implementing Positive Language in Anesthesia: Utilizing the Comfort Scale

Implementing Positive Language in Anesthesia: Utilizing the Comfort Scale Tricia Oakes & Elisabeth Prehm Faculty Sponsor: Pamela Schwartz DNP, CRNA Background Verbal numeric pain scales (ranking pain on a scale from zero to ten) are widely utilized and taught in medicine. Evidence-based research has shown that verbal numeric comfort scales are associated with a decrease in opioid administration, improved pain perceptions, and overall better patient satisfaction .7 Objective The purpose of this study is to assess the impact of a video-based educational tool demonstrating the use of a comfort scale in the perioperative setting among Nurse Anesthesia Trainees (NATs), and to examine sociodemographic factors and knowledge score for any significant association with the NATs’ willingness to incorporate the VNRS comfort scale into practice. Methods A pre-test, post-test study design was used for the conduct of the study. Fifty-six NATs from NorthShore University HealthSystem School of Nurse Anesthesia completed the pre- and post-test surveys that examined the effects of the video on the participants’ knowledge regarding the use of the VNRS comfort scale. Results The paired t test analysis revealed a statistically significant difference in the means score between the pre- and post-test surveys (p\u3c 0.01, t= -10.44; df= 55). Additionally, on the post-test, 100% of NATs (n=56) responded that yes, they would incorporate the comfort scale into their practice. Conclusion This could have significant impacts on future interactions with patients, as providers may be more inclined to use the comfort scale in their practice.

Coupled coating formation simulation in thermal spray processes using CFD and FEM

This paper deals with the simulation of coating formation in Thermal Spray processes. That means that impingement and flattening of molten metal- or ceramic particles with a diameter of about 50 microns on a rough surface have to be regarded. In this work, this is accomplished use of the Volume of Fluid method. The disadvantage here is that only the pure flattening process can be considered. In order to implicate the shrinking of the particles due to cooling down after solidification, which is responsible for the occurrence of pores and thermal stresses, a Finite Element calculation is done subsequent to the CFD calculation. After the FEM calculation has finished, the newly generated, shrinked particle shape has to be re-imported into the CFD grid. © 2009-2012.DFG/PAK193DFG/BA 851/92-

Formation of a Double Diamond Cubic Phase by Thermotropic Liquid Crystalline Self-Assembly of Bundled Bolaamphiphiles

A quaternary amphiphile with swallow-tail side groups displays a new bicontinuous thermotropic cubic phase with symmetry Pn3‾ m and formed by two interpenetrating networks where cylindrical segments are linked by H bonds at tetrahedral junctions. Each network segment contains two bundles, each containing 12 rod-like mesogens, lying along the segment axis. This assembly leads to the first thermotropic structure of the "double diamond" type. A quantitative geometric model is proposed to explain the occurrence of this rare phase

A food aid strategy for Haiti : maximizing developmental effectiveness

"The country of Haiti stands at a critical threshold for shaping its political and economic future. Concerted, visionary leadership must be put in place in order to guide the re-shaping of the Haitian economy. The purpose of this report is to provide a basis for USAID decisions about the role that its policies may play in a comprehensive agricultural development strategy for Haiti in order to insure that food needs of the country are met and that hunger and malnutrition are eliminated. Hence, both targeted projects and sectoral reforms must be addressed. Haiti presents a classic case of the political economy of hunger. Hunger and malnutrition plague the lives of a high proportion of the population, particularly the rural poor. Yet, the thrust of government policies, perhaps by necessity, has been directed toward meeting the food needs of a growing urban population. Inadequate attention has been given to developing the adaptive research and extension delivery system that will be required in order to generate major improvements in agricultural production and food distribution. The agricultural sector must play a vital role in the future in insuring that the balance-of-payments and economic growth targets of the country are achieved. Pricing policies, import regulations, and investment strategies should be designed to strengthen the developmental role of agriculture. Food aid has been used in the past to help meet the food needs of the country. Sudden periods of shortages that threaten to drive prices up too suddenly have been supplemented by food aid. Yet, the prices of domestically produced grains have risen more rapidly than the prices of imported food grains, principally wheat, minimizing the concern about price disincentives created by food aid imports. Future policy reform and sustained economic growth will require that food aid be used as a developmental resource and be fully integrated into the agricultural development strategy of the country. Its role in contributing to human resource enhancement and in capital formation that yields more secure, permanent income streams to rural residents through effectively implemented projects must be addressed."--Introduction.Dr. Brady J.

Hyaluronate levels in donor organ washout effluents: a simple and predictive parameter of graft viability

The principal cause of primary non-function in orthotopic liver transplantation is thought to be preservation injury to the microvasculature. We, therefore, evaluated if effluent levels of hyaluronate, whose uptake is an endothelial cell marker, could predict early graft function and ultimate graft outcome in orthotopic liver transplantation. A total of 102 cases were studied in two phases. In the first phase, we attempted to determine if a correlation existed between effluent hyaluronate levels, early graft function and ultimate graft outcome. This phase of the study was also used to determine hypothetical cut-off values for hyaluronate which could discriminate between good and bad livers. Thirty-two livers orthotopically transplanted to randomly selected primary recipients were studied. After varying periods of static cold storage (4°C) in University of Wisconsin solution, the livers were reinfused with cold (4°C) lactated Ringer’s solution. The first 50 ml of the reperfusion effluent was collected from the infrahepatic vena cava. Effluent samples were analyzed for hyaluronate. Linear regression analysis demonstrated a significant correlation between effluent hyaluronate levels and post-operative aspartate and alanine aminotransferase levels (p<0.001 for both). Logistic regression demonstrated a highly significant correlation (p = 0.0056) between effluent hyaluronate levels and ultimate graft outcome. Generation of Receiver Characteristics Curves indicated that a level between 400 and 430 μg·l(−1) could possibly discriminate between good livers and those at risk of early graft failure. The authenticity of this hyaluronate cut-off level was further confirmed in the second phase of the study where 70 consecutive primary crossmatch-negative transplants were performed. A highly significant difference was observed in peak aspartate and alanine aminotransferase levels in the first week (p<0.0006 and p<0.0005, respectively) between livers with effluent hyaluronate levels≤400 μg·l(−1) and livers with hyaluronate levels higher than 400 μg·l(−1) Logistic regression revealed a highly significant correlation between effluent hyaluronate levels and graft success (p=0.0001). Since hyaluronate uptake by the microvascular endothelial cell is significantly greater than production, high hyaluronate effluent levels in failed livers would be due to decreased hyaluronate uptake by the injured microvascular endothelial cell. We therefore conclude that effluent hyaluronate levels may prove to be a reliable preoperative test to assess early graft function and outcome in clinical orthotopic liver transplantation
