HI intensity mapping: Impact of primary beam effects
(University of the Western Cape, 2023)
Neutral hydrogen (HI) intensity mapping surveys with upcoming and future radio telescopes
such as the MeerKAT, a precursor to the Square Kilometre Array Observatory
(SKAO) MID telescope, have great potential for constraining ...
Aluminium induced crystallization of hydrogenated amorphous silicon thin films
(University of the Western Cape, 2005)
This study was carried out to crystallize hydrogenated amorphous silicon (a-Si:H) thin films using the aluminium induced crystallization (AIC) technique. This was done to investigate whether is there any lateral crystallization ...
Search for tetrahedral bands in yb isotopes
(University of the Western Cape, 2007)
Calculations by Dudek et al. predict shell gaps for tetrahedrally shaped nuclei at various proton and neutron numbers. 160Yb is expected to be a favourable nucleus, with tetrahedral bands predicted to lie 1 MeV above the ...
Investigation of stains existing on fossil samples from the sterkfonfein archeaologica sites
(University of the Western Cape, 2006)
It is known that fossilized bone samples excavated from the Sterkfontein archaeological sites have prominent brown stains on their surfaces. Their existence has been postulated by researchers from Transvaal museum to be ...
The determination of excitation functions for natRb+p up to 100 MeV with an emphasis on the production of 82Sr
(UWC, 2000)
The radioisotope strontiuur-S2 (T172= 25.55 days) decays to short-lived t"Rb 1T,, = 76 seconds) by l00o/o electron caphue @C). The short-lived t'*Rb decays by g5.SYopositron-ernissiou p* and 4.5%oEC to stable'2Kr. Rubidiurn-82g ...
Antimicrobial activity of South African red algal secondary metabolites
(UWC, 2001)
Infectious diseases, for example, measles, scarlet fever, malaria, tuberculosis, and cholera have claimed many lives. These infections are caused by pathogenic viruses, bacteria, or fungi that invade the body's tissues and ...
The influence of maternal nicotine exposure on neonatal rat trachea development and alveoli status
(University of the Western Cape, 2000)
The aim of this study was to determine the effect of maternal nicotine exposure on
the status of the rat tracheal development as well as the rat lung of 7 to 42 day old
offspring. Wistar dams were injected subcutaneously, ...
Spin and parity assignment in 152gd investigating octupole structures
(University of the Western Cape, 2008)
Spin and parity assignment in 152gd investigating octupole structures
The high-spin states of the nucleus ls2cd have been populated via the ls2sm (cr, 4n)
152Gd fusion-evaporation reaction at abeam energy of 45MeV. The ...
Pre-equilibrium cross section calculations with a realistic effective nucleon-nucleon interaction
(University of the Western Cape, 1995)
The principle aim of this work is to improve the way in which pre-equilibrium double differential
cross-sections are currently calculated [1, 2, 3, 4]. The theoretical basis for these
calculations is the Multistep Direct ...
Cross-sectional transmission electron microscopy of nickel silicide formation
(University of the Western Cape, 1993)
Silicides play a significant role in modern device technology. The operation of electronic devices heavily relies on the specific properties of metal-semiconductor interfaces. Although semiconductor technology has proven ...
