Report describes the procedures and techniques used in the application of a ceramic coating and the evaluation of test parts through observation of the cracks that occur in this coating due to loading

Breaking it down : contributing factors to racial identity development in elementary and middle school youth : a project based on an investigation at Manhattan Country School, New York, NY

The purpose of this qualitative study was to explore which aspects of a multiracial elementary school most contributed to the racial identity development of alumni. The central question asked of the participants was Do you believe that attending Manhattan Country School affected your racial identity development? The outcomes of this project can be useful for educators and administrators in both public and independent school settings to understand how best to help their students develop a healthy racial identity. This information may also be useful for clinicians working with young people in an effort to explore their sense of self in a racial context. The participants were all alumni who graduated from Manhattan Country School a small, independent elementary school based in New York City. The sample had three specific characteristics: 1. all alumni attended the school for a minimum of four years, 2. all alumni graduated from the school during the 1980\u27s or the 1990\u27s, 3. and the sample strove to be as gender and racially balanced as possible. The findings show that the most relevant contributing factor to their racial identity was the school culture as defined by the curriculum, the faculty and the student demographics. An unexpected second finding was that the participants all had a difficult adjustment to life after MCS due to less racially diverse high schools lacking a focus on issues of difference

Nonlinear propagation of two-dimensional gravity wave trains in magnetohydrodynamics

Nonlinear evolution of modulated two-dimensional gravity wave trains in a conducting fluid subject to a tangential applied magnetic field are considered. The effect of the applied magnetic field on the stability of the modulation and on the saturation amplitude in the long-time evolution are examined

Magnetohydrodynamic boundary layer on a flat plate: Further analytic results

Further analytic results are deduced with the magnetohydrodynamic boundary layer equations for a flat plate. The asymptotic behavior of the solutions is deduced using the scaling group method. Then, an analytic perturbative procedure is used to determine an approximate solution that exhibits this asymptotic behavior

Analytical and Numerical Solutions of Nonlinear Differential Equations Arising in Non-Newtonian Fluid Flows

AbstractSolutions for a class of nonlinear second order differential equations, arising in a viscoelastic fluid flow at a rotating cylinder, are obtained. Furthermore, using the Shauder theory and the perturbation technique existence, uniqueness and analyticity results are established. Moreover, the exact analytical solutions (in integral form) are compared with the corresponding numerical ones
