Synthesis and characterization of highly conductive charge-transfer complexes using positron annihilation spectroscopy.
(2012)
Molecular charge-transfer complexes of the tetramethylethylenediamine (TMEDA) with picric acid (Pi-OH), benzene-1,4-diol (QL), tin(IV) tetrachloride (SnCl(4)), iodine, bromine, and zinc chloride (ZnCl(2)) have been synthesized ...
HIV Positive Women's Perceptions of Stigma in Health Care Settings in Western Cape, South Africa.
(2012)
We explored the cultural context of HIV positive women's perceptions of stigma in health care settings in Western Cape, South Africa. We conducted seven focus groups with women living with HIV/AIDS in Gugulethu and ...
Creutzfeldt-Jakob disease in Kenya.
(2005)
To study the pattern of occurrence of Creutzfeldt-Jakob disease (CJD) in Kenya. Study design Prospective, cross-sectional, descriptive study of clinical, encephalographic and natural history of CJD, backed by histology in ...
Multivariate statistical analysis of radioactive variables in two phosphate ores from Sudan.
(2012)
Multivariate statistical techniques are efficient ways to display complex relationships among many objects. An attempt was made to study the radioactive data in two types of Sudanese phosphate deposits; Kurun and Uro ...
Preparation, spectroscopic and thermal characterization of new charge-transfer complexes of ethidium bromide with π-acceptors. In vitro biological activity studies.
(2013)
Ethidium bromide (EtBr) is a strong DNA binder and has been widely used to probe DNA structure in drug-DNA and protein-DNA interaction. Four new charge-transfer (CT) complexes consisting of EtBr as donor and quinol (QL), ...

(2005)
To find out if there is any association between serum uric acid level and positional vertigo.
A prospective, case controlled study.
A private neurological clinic.
All patients presenting with vertigo.

Gas--liquid chromatographic assay of aminoglutethimide and a high-performance liquid chromatographic assay for its acetyl metabolite in biological fluids.
(1984)
A rapid, sensitive and selective gas--liquid chromatographic assay for aminoglutethimide is described. The same extraction procedure may be employed prior to a high-performance liquid chromatographic assay for acetamidog ...
Intermolecular hydrogen bond complexes by in situ charge transfer complexation of o-tolidine with picric and chloranilic acids.
(2011)
A two new charge transfer complexes formed from the interactions between o-tolidine (o-TOL) and picric (PA) or chloranilic (CA) acids, with the compositions, [(o-TOL)(PA)(2)] and [(o-TOL)(CA)(2)] have been prepared. The ...
Detection of antibodies to Leishmania donovani in animals in a kala-azar endemic region in eastern Sudan: a preliminary report.
(2000)
The prevalence of antibodies against Leishmania donovani in selected domestic and wild animal species in 2 villages in Sudan with active L. donovani transmission in humans was investigated. Screening of domestic animals ...
[Classification of the avian summer population of the Western Siberian plain].
(2001)
The proposed classification system reflects the difference between the three population systems: unbuilt land, built-up land, and aquatic-semiaquatic communities. Two superorder groups--north and median--further divided ...
