The nature of the microjy source population
(University of the Western Cape, 2015)The study of the faint radio universe and of its properties has recently become a very active field of research not only because of the much improved capabilities of the SKA pathfinders but also because of the need to ... -
Neuropharmacological profile of Mentha longifolia: Effects on convulsion, nociception and pentobarbitone-induced sleep in mice
(University of the Western Cape, 2004)Mentha longifolia Huds., subspecies, capensis Briq, a plant species used for the treatment of epilepsy, painful conditions such as headache and toothache, and insomnia amongst other ailments, was investigated for anticonvulsant, ... -
Neutral hydrogen in galaxies, its content and the effect of environment on its evolution
(University of the Western Cape, 2018)Using two hydrodynamic galaxy formation simulations from the Mufasa project that I helped develop, we aim to better understand the relationship between galaxy evolution and its cold gas content commonly known as the ... -
Neutral hydrogen intensity mapping on small scales using MeerKAT
(University of the Western Cape, 2021)In the post-reionisation universe, intensity mapping (IM) with the 21 cm line of neutral hydrogen (HI) provides a potential means of probing the large-scale structure of the universe. With such a probe, a wide variety of ... -

New bands in ¹⁹²Tl using gamma spectroscopy techniques
(University of the Western Cape, 2011)High spin excited stats in¹⁹²Tl were studied using gamma-ray spectroscopy. The study included taking an active part in performing the experiment, understanding the experimental procedure, electronics and data acquisition ... -
New Collective structures in the Z=76 stable odd neutron nucleus, 187Os
(University of the Western Cape, 2021)Low- and medium-spin bands of 187Os have been studied using the AFRODITE array, following the 186W(4He,3n)187Os reaction at a beam energy of 37 MeV. The measurements of γ − γ coincidences, angular distribution ratios (RAD), ... -

New genetic tools to engineer starch production in crops
(University of the Western Cape, 2014)Starch is a major carbohydrate reserve in many plants, providing energy during heterotrophic growth and it is contained in large amounts in staple foods such as potatoes, wheat, maize, rice, sorghum and cassava. Apart from ... -
Next generation bulk Heterojunction organic Photovoltaic and light emitting diode sytems of Novel Polycyclic Aromatic Hydrocarbon, Polyfluorenes and Polythiophenes
(University of the Western Cape, 2017)In these times of diminishing reserve of fossil fuel, the development of novel - green or renewable? technologies to meet the increasing worldwide demand for energy is of great importance. The sun is the largest carbon ... -
Next generation sequencing approaches for novel gene discovery in South African Parkinson’s disease families
(University of the Western Cape, 2022)In the last decade, next-generation sequencing (NGS) approaches have revolutionised the study of human genomics, particularly aiding the understanding of genetic diseases. Parkinson’s disease (PD) is a complex neurodegenerative ... -
Nial and steel as matrices and tic and oxynitrides as reinforcements in metal-matrix composite fabrication
(University of Western Cape, 2021)Metal matrix composites harness the superior attributes of their individual constituents to form high performance materials that would rather be impossible from monolithic substances. Owing to many possible combinations, ... -
Nitrogen and argon treatment of titanium dioxide nanowire arrays
(University of the Western Cape, 2021)TiO2 nanoparticle films are important electron transport layers (ETLs) in photovoltaics such as dye-sensitised, perovskite and polymer hetero-junction solar cells. These films, however, have significant electron trap-sites ... -

Nitrogen and carbon costs of growth and antioxidant production during acclimation to environmental stress in two species of gethyllis
(University of the Western Cape, 2012)Gethyllis multifolia L. Bolus and G. villosa Thunb. are winter-growing, summerblooming,deciduous and bulbous geophytes that grow naturally in the semi-arid succulent Karoo biome of South Africa. Both species grow under ... -

The non-cancellation groups of certain groups which are split extensions of a finite abelian group by a finite rank free abelian group
(University of the Western Cape, 2008)The groups we consider in this study belong to the class X0 of all nitely generated groups with nite commutator subgroups. We shall eventually narrow down to the groups of the form T owZn for some n 2 N and some nite ... -
