OBJECTIVE The purpose of this analysis was to examine quality of life and dissociation in anxiety disorder subjects with histories of trauma, some of whom met criteria for posttraumatic stress disorder (PTSD). METHOD Subjects came from a prospective, longitudinal study of anxiety disorders. Information was gathered on role, social life, suicide attempts, psychiatric hospitalization, alcohol a...

A variable sensitivity displacement interferometer ~VSDI! used to monitor both normal and in-plane particle displacements in stress wave propagation experiments is introduced. The general system consists of two interferometers working in tandem. Normally reflected light is interfered with each of two symmetrically diffracted light beams generated by the specimen rear surface. In cases where the...

High-altitude natives have distinctive biological characteristics that appear to offset the stress of hypoxia. Evolutionary theory reasons that they reflect genetic adaptations resulting from natural selection on traits with heritable variation. Furthermore, high-altitude natives of the Andean and Tibetan Plateaus differ from one another, perhaps resulting from different evolutionary histories....

The recovery movement is reshaping approaches to treatment of mental illness, substance abuse, and traumatic stress disorders. Yet recovery principles have not been well integrated into the homeless assistance network, despite high prevalence of mental illness, substance abuse, and trauma histories among people who are chronically homeless in the United States. We review approaches to recovery ...

The rheological, structural, and stress evolution of aqueous alumina (Al2O3):latex tape-cast layers of varying composition were studied by shear rheology, direct visualization, and a controlled environment stress measurement device. Their low shear viscosity was nearly independent of the alumina:latex ratio for binary mixtures whose particle size ratio ( D alumina:D latex) approached unity, but...

The present paper reports on the use of Modified Wöhler Curve Method (MWCM) applied along with nominal stresses to estimate lifetime notched additively manufactured metallic materials subjected constant and variable amplitude multiaxial fatigue loading. MWCM is by defining critical plane via direction that experiences maximum variance resolved shear stress. In this setting, owing fact stress a ...

And because it is surrounded by an array of 60,000 photo-voltaic cells, the academy will produce more than five per cent of its electricity and overall use around a third less energy than the maximum allowed by San Francisco's already strict laws. " We could have thought of a different solution for the roof without plants and birds, " says Piano. " But the green roof is about a new spirit for t...
