Book Review: James L. Drexler, Editor. Schools as Communities: Educational Leadership, Relationships, and the Eternal Value of Christian Schooling.

Anyone who has engaged in the calling of Christian education knows that it can be — and usually is — one of the most exciting, delightful, fulfilling, and joyous ministries that a believer can know. Its golden days are a real “foretaste of glory divine,” its opportunities for those who truly love the possibilities of the mind and heart of Christ in the lives of our students are the very aroma of the Lord in our work. Lives are changed; parents are supportive; administrators are helpful; the board is productive. Sacrifices are engaged willingly, trials are gladly borne. We go home at the end of the day, and can hardly wait to return in the morning

Charge distributions near metal-dielectric interfaces before and after dielectric surface flashover

A technique was developed for measuring surface charge distribution near interfaces without placing any measuring apparatus near the face of the samples. The results of measurements which were made on FEP Teflon and Kapton dielectrics, before and after are given flashover, with various types of interfaces. Also given are data showing mean time between flashovers for various configurations exposed to a variety of environmental conditions. Several charge transfer mechanisms are considered as a means by which stable charge distributions may be maintained near interfaces

Book Review: William Jeynes. Religion, Education, and Academic Success

In this provocative work, Dr. William Jeynes of California State University at Long Beach addresses a vital educational question: is there a statistically verifiable relationship between religious belief and academic achievement? For the non- Christian, it is a question of the social utility of religion; does a demonstrable and significant correlation between a religious mindset and measurable academic outcomes exist? Or is a secular outlook equally capable of superior educational success? For the Christian thinker, it is a question of the relationship between the root of faith and the fruit of the “strong mind” (II Tim. 1:7) promised in the scriptures. Can this be translated into statistical categories like “religious people” and “religious institutions” for investigation? If so, how can this be done

Microwave power transmission system wherein level of transmitted power is controlled by reflections from receiver

A microwave, wireless, power transmission system is described in which the transmitted power level is adjusted to correspond with power required at a remote receiving station. Deviations in power load produce an antenna impedance mismatch causing variations in energy reflected by the power receiving antenna employed by the receiving station. The variations in reflected energy are sensed by a receiving antenna at the transmitting station and used to control the output power of a power transmitter

Degenerate elliptic operators: capacity, flux and separation

Let $S=\{S_t\}_{t\geq0}$ be the semigroup generated on L_2(\Ri^d) by a self-adjoint, second-order, divergence-form, elliptic operator $H$ with Lipschitz continuous coefficients. Further let $\Omega$ be an open subset of \Ri^d with Lipschitz continuous boundary $\partial\Omega$. We prove that $S$ leaves $L_2(\Omega)$ invariant if, and only if, the capacity of the boundary with respect to $H$ is zero or if, and only if, the energy flux across the boundary is zero. The global result is based on an analogous local result.Comment: 18 page
