The anti-estrogenic properties of birdsfoot trefoil (Lotus corniculatus) and yellow pine (Pinus ponderosa) needles were studied. Oral administration of a water-soluble fraction of an acetone extract of birdsfoot trefoil was found to decrease uterine weight of immature female mice. The estrous cycles of rats receiving this extract in the ration, were not disturbed. Specially prepared aqueous fractions of an acetone extract of yellow pine needles decreased the uterine weight of mice. In further experiments, immature female mice were fed 0.040 mcgms. and 0.020 mcgms. diethylstilbestrol (D.E.S.) per gram of feed. When a water-soluble fraction of pine needle extract was administered, it did not affect uterine weight significantly in the 0.040 mcgm. D.E.S. group, but markedly and significantly decreased uterine weight in the 0.020 mcgm. D.E.S. group. This pine needle extract also interrupted the estrous cycles of mature rats, causing a prolonged diestrus. Chromatographic studies indicated that the pine extracts probably do not owe their anti-estrogenic activity to pinosylvin or its mono-methyl ether. / Land and Food Systems, Faculty of / Graduate

Submitted in fulfillment of the requirements for degree: MASTER OF ARTS in the department of GENERAL LINGUISTICS at the UNIVERSITY OF ZULULAND, 2010. / The objective of this study was to determine learner errors in both rural and urban schools. The first aim was to determine through literature the types of errors and their probable causes. The second aim was to conduct an investigation into errors committed by learners and experienced by educators from learners. The questionnaires were developed by the researcher for both educators of English as a second language and learners of English as a second language. By using the questionnaires the researcher was interested in determining whether factors such as lack of resources such as libraries, learning material, under qualification in English as a subject, lack of training in the structure of English and other factors had any influence in the committing of errors by learners. In terms of factors associated with errors, the most common factor to which all educators responded as a causal factor was the lack of facilities, among others, was the shortage of libraries and library books in cases where there are libraries. One other factor which was prominent was the lack of training in the structure of English as a subject. The last chapter of this investigation recommends a variety of strategies that could be employed both by the educators and the Department of Education to minimise English errors among learners of English.
