We develop a general procedure for estimating the effective constitutive behavior of nonlinear dielectrics. The procedure is based on a variational principle expressing the effective energy function of a given nonlinear composite in terms of the effective energy functions of the class of linear comparison composites. This provides an automatic procedure for converting well-known information for...

Current Problems in Surgery keeps readers up-to-date on the latest surgical advances. Each month, this publication examines a single clinical problem or condition commonly seen by general surgeons. Issues also focus on topics in surgical research and emerging ideas in surgical subspecialties. Current Problems in Surgery is ideal for information too urgent to await book publication, yet too impo...

When the World Trade Centre was destroyed in New York on 11 September 2001, I felt devastation for all the victims of this atrocity. This included the terrorist themselves as well as the families of the dead and injured and of the perpetrators. When America used this atrocity as a reason to attack Iraq I was very disturbed by the transposition of lines of blame to a country that had no direct l...

We present predictions of a relatively simple model of the low-lying 0+ states in 12Be, their predicted energy splitting in 12O, their cross-section ratios in 10Be(t,p) and 14C(p, t) and their decay widths. Comparison is made with predictions using earlier wave functions of Barker. Disciplines Physical Sciences and Mathematics | Physics Comments Suggested Citation: Fortune, H.T. and Sherr, R. (...

This paper is an attempt to distinguish and discuss the Iranian (as distinct from the Turkish, Arabic and Islamic) elements in the present pattern of kinship and marriage practice in Persia in their historical context. This will entail also a discussion of what can be known of the pre-Islamic Iranian system. Disciplines Anthropology | Social and Behavioral Sciences This journal article is avail...

Conducting research in the acutely ill and injured is important to broaden the scientific foundation of nursing practice for the specialty. Given the nature of acute illness, challenges to the collection of self-report data are numerous, but they are not insurmountable. Attending to these challenges and planning for strategies to enhance the accuracy of data are important tasks for any investig...

Scientific investigation of mechanisms that determine lifespan can be divided into three general approaches. The first approach (the comparative method) began over a century ago comparing species differing greatly in maximum longevity and implicated a role for the speed of metabolism in determining the length of life [1]. The second approach commenced after the 1930s investigated the mechanisms...

Coulomb energy calculations for the lowest 0+ , T = 2 state in A = 16 nuclei allow tight constraints on the masses of the lowest 1/2+ , T = 3/2 state in 15O and 15F, and of the 0+ , T = 2 state in 16F.

We use a weak-coupling procedure and results of a shell-model calculation to compute the two-proton separation energy of 19Mg. Our result is at the upper end of the previous range, but 19Mg is still bound for single proton decay to 18Na. We also calculate the 2p decay width.
