Time-resolved, Gas-phase Kinetic and Quantum Chemical Studies of the Reaction of Germylene with Hydrogen Chloride.

Time-resolved studies of germylene, GeH , generated by laser flash photolysis of 3,4-dimethyl-1-germacyclopent-3-ene at 193 nm and monitored by laser absorption, have been carried out to obtain rate constants for its bimolecular reaction with HCl. The reaction was studied in the gas phase, mainly at a total pressure of 10 Torr (in SF bath gas) at five temperatures in the range 295-558 K. Experiments at other pressures showed that these rate constants were unaffected by pressure.

Increasing nurse practitioner students' comfort levels in caring for veterans with post-traumatic stress disorder.

Few nurse practitioner programs integrate education on care of veterans into their curriculum. Because more veterans are seeking health care outside of the Veteran Affairs system, all advanced practice nurses need to be prepared to meet the unique needs of veterans with post-traumatic stress disorder (PTSD). The authors developed an education session on military-to-civilian transition and screening and treatment of veterans with PTSD.

Time-Resolved Gas-Phase Kinetic, Quantum Chemical, and RRKM Studies of the Reaction of Silylene with 2,5-Dihydrofuran.

Time-resolved kinetics studies of silylene, SiH2, generated by laser flash photolysis of phenylsilane, were performed to obtain rate coefficients for its bimolecular reaction with 2,5-dihydrofuran (2,5-DHF). The reaction was studied in the gas phase over the pressure range of 1-100 Torr in SF6 bath gas, at five temperatures in the range of 296-598 K. The reaction showed pressure dependences characteristic of a third body assisted association.

Reaction of silylene with sulfur dioxide: some gas-phase kinetic and theoretical studies.

Time-resolved kinetic studies of the reaction of silylene, SiH2, with SO2 have been carried out in the gas phase over the temperature range 297-609 K, using laser flash photolysis to generate and monitor SiH2. The second order rate coefficients at 1.3 kPa (SF6 bath gas) fitted the Arrhenius equation: log(k/cm(3) molecule(-1) s(-1)) = (-10.

The paradox of risk: historically black college/university students and sexual health.

Objective: This literature review provides an analysis of the current state of the empirical research on sexual health among students attending historically black colleges and universities (HBCUs).

Methods: Several electronic databases were used to identify 24 empirical studies that met criteria for inclusion in this review.

Results: The results indicated that perceived human immunodeficiency virus (HIV) risk, religiosity, HIV testing, condom use, and substance use were as high or higher for black HBCU students in comparison with students of other racial/ethnic groups.
