Triterpene glycosides chemically defend the south african kelp bed sea cucumber, Pseudocnella insolens (echinodermata : holothu roidea), against predation.
(University of the Western Cape, 1997)
The small, subtidal sea cucumber, Pseudocnella insolens appears to have
no obvious protection from predation, yet it occurs in dense colonies covering rocky areas
and appears to have few predators. Laboratory-based feeding ...
Genetic variation among verticillium dahliae isolates using pathogenicity and aflp analysis
(University of the Western Cape, 1999)
Soilborne plant pathogenic fungi have had an important economic and social impact on humans since the evolution of agricultural societies (Stakman, 1959). In South Africa, the soilborne pathogen Verticillium dahliae Kleb, ...
An assessment of the virulence of listeria spp. isolated from raw milk and raw chicken
(University of the Western Cape, 1994)
Listeria a f~rn__e pathogen is the etiological agent of the deadly
disease listeriosis. Although, the virulence traits of international isolates of
Listeria are well studied, nothing is known about the virulence traits ...
A critical analysis of aspects pertaining to the teaching of the ecology section of the standard eight biology syllabus.
(University of the Western Cape, 1991)
In this study an attempt has been made to investigate how the
Ecology section (suitable for fostering awareness and concern for
the environment) of the standard eight Biology syllabus is
taught. Since fieldwork and ...
Conjugacy classes of some projective linear groups
(University of the Western Cape, 1992)
Given a finite set X of distinct symbols the symmetric group Sx and the alternating group Ax are obtained without further constructions. More interesting groups are contrived, however, by imposing a certain structure on ...
Left versus right canonical wiener-hopf factorization for rational matrix functions: an alternative version
(University of the Western Cape, 1995)
It is an established fact that both canonical and non-canonical Wiener-hopf factorizations of matrix functions play an important role in various aspects of mathematical analysis and its applications. Indeed, for instance, ...
The influence of maternal nicotine exposure on development lung as gas exchanger: the protective effect of copper
(University of the Western Cape, 1998)
The influence of tobacco smoking on the developing fetus is well reported. Maternal nicotine exposure during pregnancy and lactation interferes with fetal and neonatal lung growth and development, rendering the lungs more ...
(p.n.) Reactions on 59co in the intermediate energy range
(University of the Western Cape, 1992)
Detailed theoretical investigations [Chi80,Mos82,Kle85] of (p,n) and (p,p') data
indicate that the reaction mechanisms operative at intermediate energies and for
energy losses up to several tens of MeV are predominantly ...
The chemical groundwater characteristics of the Sutherland area, Northern Cape
(University of the Western Cape, 1998)
The objectives of the project were to establish, identify, interpret and map the chemical groundwater composition of the area surrounding the town of sutherland' Processes that govern the groundwater chemistry of the area ...
Structural and functional aspects of sperm after transit through the fallopian tube of the sheep
(University of the Western Cape, 1996)
Ejaculated mammalian spermatozoa have the potential for fertilization. The acquisition of the ability to fertilize a fully invested oocyte occurs during the passage through the female reproductive tract. These post-ejaculatory ...
