Syntheses and crystal structures of neutral oxorhenium(V) complexes of N2O2-donor tripodal ligands

Abstract: The neutral distorted octahedral complexes [ReOCl(L)] {H2L = N,N-bis(2-hydroxybenzyl)-2-(2-aminoethyl)dimethylamine (H2had); N,N-bis(2-hydroxybenzyl)-aminomethylpyridine (H2hap); N,N-bis(2-hydroxybenzyl)-2-(2-aminoethyl)pyridine (H2hae)} were prepared by the reaction of trans-[ReOCl3(PPh3)2] with a twofold molar excess of H2L in ethanol. X-ray structure determinations of [ReOCl(had)] (1) and [ReOCl(hap)] (2) were performed, and the structures compared. In both complexes the choride is coordinated trans to the tripodal tertiary amino nitrogen, with a phenolate oxygen trans to the oxo oxygen.

Hiv/aids in construction: are older workers aware?

Abstract: The New Partnership for Africa's Development (NEPAD) (2001) urges African leaders to take responsibility for revitalizing and extending the provision of education, technical training and health services with high priority given to tackling HIV/AIDS, TB and other communicable diseases. The International Labor Organization (ILO) and the World Health Organization (WHO) both agree that occupational health and safety in Africa needs strengthening. In support of this realization are the need to maintain and promote workers' health and working capacity. The fight against HIV/AIDS in the workplace is a continental priority. In the absence of any other definitive or similar study, this study aims to establish a valid baseline assessment of the levels of knowledge, types of attitudes, perceptions and beliefs of older construction workers in South Africa regarding HIV infection and AIDS. This paper reports only on findings concerning the level of knowledge and awareness of HIV/AIDS among older construction workers as determined during the first phase of an exploratory study commenced in August 2002. Older construction workers generally had acceptable levels of correct knowledge, perceptions and attitudes on most issues relative to the disease. However, their employers had not played a major contributory role. The study highlighted several areas where older workers either had incorrect and deficient knowledge and attitudes or demonstrated high levels of uncertainty.

Stress and the Part-Time Student: Work Factors Associated with Failure Rate

Abstract: The purpose of this study was to determine the relationship between four variables, namely, role ambiguity, role conflict, the resultant stress, and failure rate of the working part-time student. A...
