Die bydrae van die sandfraksie tot katioonadsorpsie in gronde
(North-West University (South Africa), 1972)Models that have been set up to explain cation adsorption in soils and clay minerals are based on cation exchange. The applicability of the models depend to a great extent on the experimental terms in the adsorption equation. ... -

Die invloed van droogtetoestande op die stikstofmetabolisme van twee mielielyne
(North-West University (South Africa), 1978)Two maize lines, A281 and G556DT, were investigated to ascertain the effect of drought conditions on the following aspects of the water relations and nitrogen metabolism: relative percentage water deficit, total water ... -
Die effek van sikliese adenosien-3':5'-monofosfaat op hemoglobien-biosintese
(North-West University (South Africa), 1974)Although cAMP may be involved in the regulation of protein biosynthesis in certain eukaryotic cells no decisive relationship between hormonal action, cAMP and the regulation of translation could be found in the literature. ... -
Cholesterolmetabolisme tydens die opwekking en regenerasie van eksperimentele aterosklerose
(North-West University (South Africa), 1971)In the present investigation it was planned to evoke atherosclerosis in rabbits which agrees with that seen in man. For this purpose a semi- synthetic diet with a high fat content was used. Although an atherogenic state, ... -
