The use of prescription medication and other drugs by New Zealand drivers with illegal blood alcohol levels.

Objective: This study examined the prevalence of the use of prescription medicines and other drugs by a selected subgroup of New Zealand drivers. The use of potentially impairing prescription drugs by the driving population is largely unknown. The population studied was drivers who were stopped by police, failed a breath alcohol test, elected to provide a blood sample for laboratory analysis, and had blood alcohol levels exceeding the legal limit.

Molecular Dynamics Investigation of Beryllium Complexes.

Structures of aqueous [Be(HO)], its outer-sphere and inner-sphere complexes with F, Cl, and SO, and dinuclear complexes with a [Be(κ-OH)(κ-SO)] core have been studied through Car-Parrinello molecular dynamics (CPMD) simulations with the BLYP functional. According to constrained CPMD/BLYP simulations and pointwise thermodynamic integration, the free energy of deprotonation of [Be(HO)] and its binding free energy with F are 9.6 and -6.

Electrospray Ionization Mass Spectrometric Study of the Gas-Phase Coordination Chemistry of Be Ions with 1,2- and 1,3-Diketone Ligands.

Electrospray ionization mass spectrometry (ESI MS) is a powerful technique for the study of coordination complexes because of its ability to analyze solution systems involving very low concentrations of metal complexes. In this work, the coordination chemistry of Be ions with a selection of well-known 1,3-diketone and related 1,2-diketone ligands has been investigated using ESI MS. With acetylacetone (Hacac), a range of acac-containing ions is observed, including [Be(acac)H], [Be(acac)(MeOH) ] ( n = 1, 2), and polynuclear species such as the dinuclear [Be(acac)] and trinuclear [BeO(acac)].
