Selected antiretroviral and anti-tuberculosis drug combinations by non-covalent bonding
(University of Western Cape, 2021)Treatment of the human immunodeficiency virus (HIV) and tuberculosis (TB) infections have become very complicated due to the advent of drug resistance. Drug combinations offer an alternative approach to reducing the emergence ... -
Selection and optimization of the seeding procedure prior to the synthesis of Pd-based membranes
(University of the Western Cape, 2014)Pd based membranes are known for their incredible selectivity towards H2. In order for Pd membranes to display high H2 selectivity, a defect free layer of Pd needs to be deposited onto a support. Although various fabrication ... -
Selection, synthesis and evaluation of novel drug-like compounds from a library of virtual compounds designed from natural products with antiplasmodial activities
(University of the Western Cape, 2020)Malaria is an infectious disease which continues to kill more than one million people every year and the African continent accounts for most of the malaria death worldwide. New classes of medicine to combat malaria are ... -
Self-tuning Linux Kernel Performance Using Support Vector Machines
(University of the Western Cape, 2006)In this chapter, we provide the motivation and background behind the automatic optimisation of an operating system. We begin with a discussion of some of the difficulties of automatic operating system optimisation and ... -
Semen characteristics of free-ranging African elephants (Loxodonta africana) and Southern white rhinoceros (Ceratotherium simum simum) using Computer-aided sperm analysis, Electron microscopy and Genomics as diagnostic tools
(University of the Western Cape, 2016)The survival of free-ranging (in situ) African elephant and Southern white rhinoceros populations are currently being challenged on a daily basis in Africa. Reproductive health is considered a vital component of species ... -
Semi-synchronous video for deaf telephony with an adapted synchronous codec
(University of the Western Cape, 2009)As Information and Communication Technology (ICT) matures, communication services must be improved to meet the needs of all types of users. For some uses, current Video over Internet Protocol (IP) brings unsatisfactory ... -
Sequence stratigraphic characterisation of petroleum reservoirs in Block 11b/12b of the Southern Outeniqua Basin
(University of the Western Cape, 2011)The main purpose of this study was to identify and characterize the various sand prone depositional facies in the deepwater Southern Outeniqua Basin which generally tend to form during lowstand (marine regression) conditions ... -
Service learning in pharmacy: Evaluation of tuberculosis screening by pharmacy students in primary health care facilities.
(University of the Western Cape, 2019)Background: Tuberculosis (TB) is one of the arms of the so-called quadruple burden of disease in South Africa. One of the major impediments to TB control is failure to detect the disease, and undiagnosed cases in the ... -
The Shallow water bryozoans of the West Coast of South Africa
(University of the Western Cape, 2005)The South African biota is characterised by high levels of diversity and endemism. While commercially viable taxa have been well-studied, cryptic organisms such as bryozoans, have been neglected in terms of study. Taxonomic ... -
Short message service normalization for communication with a health information system
(2011)Short Message Service (SMS) is one of the most popularly used services for communication between mobile phone users. In recent times it has also been proposed as a means for information access. However, there are several ... -
Signalling molecule “calcium” improves germination and growth of Sorghum bicolor seedlings under salt stress
(University of the Western Cape, 2021)Abiotic stress, mainly in the form of extreme temperatures, drought and salinity has caused major crop losses worldwide, putting a severe strain on agriculture. Salinity severely limits plant growth and productivity and ... -
Signature splitting and inversion in the 186-194 Au Nuclei predicted by the total routhian surface (TRS) and cranked shell model (CSM) calculations
(University of the Western Cape, 2007)The nearly oblate deformed Au nuclei show rotational bands built on multi quasiparticle excitations [Bou89, Bou92, Gue03, Gue01, Ven92]. Several of these bands are built on rotationally aligned high-j proton and neutron ... -
Silica Coated Core-Shell Quantum Dot-based Electro-Immunosensor for Interferon Gamma TB Disease Biomarker
(University of the Western Cape, 2020)Tuberculosis (TB) is a disease that results from infection by Mycobacterium tuberculosis, which is regarded the most common infecting organism. TB has killed countless numbers of people particularly in underdeveloped ... -
Silicon nanowires by metal-assisted chemical etching and its incorporation into hybrid solar cells
(University of Western Cape, 2021)The rapid increase in global energy demand in recent decades coupled with the adverse environmental impact of conventional fuels has led to a high demand for alternative energy sources that are sustainable and efficient. ... -
Silver-coated polyethene terephthalate membrane for detection of pharmaceuticals using surface-enhanced Raman spectroscopy
(University of the Western Cape, 2017)Surface-enhanced Raman spectroscopy (SERS) has emerged as one of the analytical tools for detection of micro pollutants in the aquatic environment. The SERS technique is touted to have fingerprinting capability, specificity, ... -
Simulating the neutral hydrogen distribution during cosmic reionization
(University of the Western Cape, 2018)We improve on the physical treatment of ionising source and sink populations in the large scale semi-numerical simulations by implementing new physically motivated parametrizations taken from high-resolution radiative ... -
Simulation of silicon and diamond detector systems by GEANT4 simulation techniques
(University of the Western Cape, 2014)There is a constant need for improvement in nuclear particle detection methods. Silicon surface barrier detectors have proved very valuable during the last decades. Diamond is a viable alternative to silicon as a semiconductor ... -
Single nucleotide polymorphism association studies of ABCA13 and ABHD11 genes and the bioinformatics analysis of the autism candidate genes localized on chromosome 7
(University of the Western Cape, 2016)Autism, Aspergers Syndrome and Pervasive Developmental Delay-Not Otherwise Specified (PDD-NOS), among others, fall under an umbrella of disorders known as Autism Spectrum Disorder. Twin studies show that autism is a highly ... -
Singular integral equations and realization: A survey of the state space method
(University of the Western Cape, 1996)Different methods for solving singular integral equations exist. One of the most recent methods is the so-called state space method. This method is based on the fact that a rational matrix function VV(^) which is analytic ... -
