(Unisa Press, 2008)The introduction of an outcomes-based curriculum in South Africa together with a new syllabus for physical sciences for grades 10–12, prompted the development of an instrument to monitor conceptual understanding in ...
-
(Elsevier, 2008)Amphetamine and related derivatives are widely abused central- and psychostimulants. Detection of certain derivatives, such as methcathinone, by commonly available immunoassay screening techniques is insufficient. Multi-analyte ...
-
(South African Chemical Institute, 2008)99mTc-DMSA (DMSA=dimercaptosuccinic acid), the gold standard for static renal imaging, has a long uptake time, which is a limiting factor in diagnostic procedures and also leads to a relatively high radiation dose to ...
-
(Southern African Association for Research in Mathematics, Science and Technology Education, 2008)Many universities in South Afirca use alternative admissions tests together with results of the Grade 12 examinations for access of placement. These tests focus on academic literacy and mathematical skills and doe not ...

(Routledge, 2009)On exposure to the potential carcinogen 1,3-butadiene, the major urinary metabolite in humans is N-acetyl-S-(3,4-dihydroxybutyl)cysteine. A novel, stereoselective synthesis of this cysteine–butadiene metabolite has ...
-
(International Union of Crystallography, 2009)The three-ring eudesmanolide, C15H16O3, is a natural product isolated from Dicoma anomala Sond. (Asteraceae). The compound contains an endo–exo cross conjugated methylenecyclohexenone ring with an envelope conformation ...
