The purpose of this study was to examine the independent and interactive effects of HIV-1 serostatus and cocaine on neuropsychological (NP) performance in a sample of 237 gay and bisexual urban-dwelling African American men. Consistent with current evidence, it was expected that the greatest neuropsychological performance deficits would be evident (1) in the symptomatic seropositives (SSPs), es...

This article describes the state of art of the research on the SSPS(Space Solar Power Station). Considering the SSPS is one of the promising clean and large-scale power source, a variety of fundamental technologies of MPT(microwave power transmission) have been developed in universities, national research institutes, space and electrical industries in Japan. SSPS system studies are also being c...

Entropy production is a key concept of thermodynamics and allows one to analyze the operation engines. For Scovil-Schulz-DuBois heat engine, archetypal three-level thermal maser coupled baths, it was argued that common definition flow may provide negative entropy for certain parameters [Boukobza Tannor, Phys. Rev. Lett. 98, 240601 (2007)]. Here, we show this can be cured if corrections detuning...

the roots and rhizomes of tanacetum parthenium (l.) schulz. bip. (asteraceae), have been used in iranian traditional medicine under the name of aqhovan, as digestive and stomachic tonic. composition of the essential oil, which was obtained from the root of t. parthenium collected from karaj, was determined by gas chromatography, combined gc/ms and gc/ir. in total, 20 components (92% of essentia...

Specialized Monte Carlo simulations and the moment free energy (MFE) method are employed to study liquid-gas phase equilibria in size-disperse fluids. The investigation is made subject to the constraint of fixed polydispersity, i.e., the form of the "parent" density distribution rho(0)(sigma) of the particle diameters sigma, is prescribed. This is the experimentally realistic scenario for, e.g....
