in this paper, the solution of a moving volterra-type screw dislocation in an orthotropic layer, bonded between two piezoelectric layers is obtained using complex fourier transform. the dislocation solution is then employed as strain nuclei to derive singular integral equations for a medium weakened by multiple moving cracks. these equations, which are classified as, cauchy singular equations, ...

The current status of the p. + -Wcollider concept is reviewed and discussed. In a reference scenario, a high-intensity pulsed proton accelerator (of K-factory class) produces large numbers of secondary 7r's in a nuclear target, which produce muons by decay . The muons are collected and cooled (by "ionization cooling") to form high-intensity bunches that are accelerated to high-energy collisions...

BACKGROUND Physical exercise can modify subsequent energy intake and appetite and may thus be of particular interest in terms of obesity treatment. However, it is still unclear whether an intensive bout of exercise can affect the energy consumption of obese children and adolescents. OBJECTIVE To compare the impact of high vs. moderate intensity exercises on subsequent 24-h energy intake, macr...

PubMed Link http://www.ncbi.nlm.nih.gov/ pubmed/2318652 This report presents a three-stage model (ARRM) that characterize people's efforts to change sexual behaviors related to HIV transmission. ARRM focuses on social and psychological factors hypothesized to influence (1) labeling of high risk behaviors as problematic, (2) making a commitment to changing high risk behaviors, and (3) seeking an...

Increased levels of physical activity may improve the lipid profile, but is this effect identical across apolipoprotein E (apoE) genotypes? A population-based cross-sectional survey conducted from 1999 to 2000 included 1708 randomly selected men and women aged 35 to 74 years. A validated physical activity questionnaire measured, for each participant, the total energy expenditure and its percent...
