Accretion onto compact stellar objects (white dwarfs, neutron stars, and black holes) from companions in close binaries is the primary beacon for study of the astrophysics of the extreme: from endpoints of stellar and binary evolution, to the physical processes in the extremes of gravity, radiation, or magnetic fi elds. Accretion from the interstellar medium on the presumed still larger populat...

The focus here is on learning by school-age children, assisted by the family and/ or peers, and supported and managed by professional teachers. Keith Topping, who specialises in researching paired learning, provides an outline of the essential concepts of peer-assisted and parent-assisted learning, followed by discussion of some specific practical evidence of its use in reading, writing, spelli...

al monogamy4 and covert sex outside the main relationship. Delayed marriage and high divorce rates mean that growing numbers of individuals experience multiple sexual partners in a lifetime, and this greatly increases their exposure to infection. Furthermore, National Health and Social Life Survey data show that around 25% of men and 10% of women report extramarital or extracohabitational affai...

The neuromuscular blocking agent cisatracurium is frequently used adjunctively in anesthesia to facilitate endotracheal intubation and to provide muscle relaxation during surgery. We aimed to determine the pharmacokinetics (PK)/pharmacodynamics (PD) of cisatracurium in patients with congenital heart defects (CHDs), such as ventricular septal defects and atrial septal defects, and to assess the ...

by MARISSA C. MERKER, M.S.C.E. Washington State University August 2010 Chair: Richard J. Watts Persulfate is a promising in situ chemical oxidation treatment (ISCO) for the remediation of low-permeability strata because it is more stable in the subsurface and can rapidly degrade recalcitrant contaminants compared to other technologies. ISCO technologies include catalyzed hydrogen peroxide propa...

IN T R O D U C T IO N: Functional activity in post-stroke survivors is often impaired and has a significant negative impact on the patient, his/her family, community and society. M A T E R IA L A ND M E T H OD S: Pilot study – a two-group, before-and-after preliminary study was carried out to investigate the feasibility of conducting a larger randomized controlled trial investigation of the eff...

A recently developed distributed feedback quantum cascade laser (QCL) capable of thermoelectric-cooled (TEC) continuous-wave (cw) operation and emitting at ∼ 9 μm is used to perform laser chemical sensing by tunable infrared spectroscopy. A quasi-continuous-wave mode of operation relying on long current pulses (∼ 5 Hz, ∼ 50% duty cycle) is utilized rather than pure cw operation in order to exte...

ZnO nanoparticles (NPs) are engineered nanoparticles used in many commercial products inclusive of cosmetics, paints, textiles, and sanitary products. ZnO NPs are potent in protecting the skin against UV radiation so, they are used as ingredients in sunscreen and moisturizing creams/lotions and hence the study of their toxicity is essential. On the one hand, nanoparticles, due to their small si...
