Abstract

In this paper, we use a very prominent technique, Hirota Bilinear Method (HBM) to survey the lump structures of the Kadomtsev-Petviashvili (KP) equation in the frame of a collisionless magnetized plasma system composed of dust grains, ions, and nonextensive electrons. Nonlinearity has worldwide applications, and soliton theory is a powerful appliance to illustrate its qualitative behaviors. So, lump solitons are very significant and also interesting. We have observed that lump structures differ due to the correlated parameters of the plasma system. It has also been found that the nonextensive parameter crucially changes the lump features., Comment: 13 pages, 25 figures

Abstract

This article reviews childcare industry through social science literature and contemporary perspectives. It was clear that although a popular small business venture, serious studies in this relatively large segment of the economy remain to be undertaken. The literature thus reviewed for the paper demonstrated both philosophical as well as empirical foundations of ethnic preference of childcare industry. A total of six illustrative hypotheses regarding managerial issues within the context of ethnic segmentation strategy were tested with data from 70 childcare centers of New York City. The empirical evidence reaffirmed in varying degrees that childcare centers tend to serve specific ethnic clientele; that the behavioral problems, discipline problems, parental complaints, funding uncertainty do vary across ethnicity. These variations pose unique managerial challenges for specific childcare centers. It was also demonstrated that profitability perception is lower in centers with predominantly African-American children. This paper found evidence in support of desegregated childcare centers. In fact, managerial issues and challenges tend to be lower in the desegregated childcare centers than the 'preferred' strategy of segregation. Some of the insignificant correlation coefficients will become significant simply with a larger sample size. It is also expected that a large sample would verify the findings on managerial issues in the context of the strategy of segregation., Introduction One of the challenges of the working mothers has been to locate an affordable childcare, especially among the low-income families. In fact, the economic burden on young dual income [...]

42. Conjugate heat transfer and effects of interfacial heat flux during the solidification process of continuous castings

Author

Abstract

The air gap formation due to metal shrinkage on the interfacial heat transfer of a continuous casting mold is studied. The study concludes that there exists a limiting value of Pe above which the effects of air gap formation on the overall heat transfer is negligible.
