Photovoltaics of selenide kesterite doped with nanoscopic iron and cerium oxyselenides
(University of Western Cape, 2021)As the demand for energy is constantly increasing, researchers are looking at various methods of energy production. Following the rise of solar energy becoming a major player, researchers are looking at kesterite materials, ... -
Phylogenetic assessment and historical biogeography of the Psammophis leightoni complex
Stable and accurate taxonomy remains a primary component of conservation. By overlooking taxonomic disorder, conservation management strategies may ineffectively distribute resources. The Psammophis leightoni species complex ... -
Phylogenetic diversity of nifH genes in Marion Island soil
(University of the Western Cape, 2006)The microbial life of sub-Antarctic islands plays a key role in the islands ecosystem, with microbial activities providing the majority of nutrients available for primary production. Knowledge of microbial diversity is ... -
Phylogenetic relationships of the subfamily petropedetinae noble, 1931 (anura: ranidae): a simultaneous analysis of morphological and molecular data
(University of the Western Cape, 2002)The Ranidae is one of the largest families of the Neobatrachia, but its taxonomy is in a state of flux. Major taxonomic rearrangements have recently been instituted for this family, but these have been mostly phenetic in ... -
Phylogeography and co-evolution of ectoparasitic mites that live on the rodent host species Lemniscomys rosalia (Rodentia: Muridea)
(University of the Western Cape, 2022)Lemniscomys rosalia is a widespread, possibly cryptic species of murid grass mouse. Cytogenetic evidence points towards cryptic speciation in L. rosalia as the eastern African karyotype (2N = 54; FNA = 62) differs from the ... -
Phylogeography and speciation in the genus arthroleptella
(2009)Moss frogs are restricted to permanently moist terrestrial habitats in the south-western Cape Fold Mountains. There is a very close association between Arthroleptella distribution and Table Mountain Sandstone. Suitable ... -
The phylogeography, epidemiology and determinants of Maize streak virus dispersal across Africa and the adjacent Indian Ocean Islands
(University of the Western Cape, 2015)Maize streak disease (MSD), caused by variants of the Maize streak virus (MSV) A strain, is the world's third and Africa’s most important maize foliar disease. Outbreaks of the disease occur frequently and in an erratic ... -
Physical and genetical investigation of the Xp11.3 region on the short arm of the human X-chromosome
(University of the Western Cape, 2004)The pattern of inactivation in the DXS8237E-UBE1-PCTK1 region is of particular interest, since the mechanisms of X chromosome inactivation and the escape from inactivation are, as yet, not fully understood. The inactivation ... -
Physical properties of vanadium dioxide nanoparticles: application as 1-d nanobelts room temperature for hydrogen gas sensing
(University of the Western Cape, 2013)Transition metal oxides magneli phases present crystallographic shear structure which is of great interest in multiple applications because of their wide range of valence, which is exhibited by the transition metals. The ... -
The physicochemical characterisation, compatibility testing and solid-state form screening of terizidone - Pyridoxine combinations
(University of Western Cape, 2021)Terizidone (TZD) is considered an essential anti-tuberculosis drug and in South Africa it is prescribed as part of the multi-drug resistant tuberculosis (MDR-TB) treatment regimen. From a literature study it became ... -
Physics graduate preparedness for work and society
(University of the Western Cape, 2023)Both internationally and in South Africa, there have been renewed debates about the purposes of higher education and the attributes that should be developed in graduates. In the field of physics, many studies have reported ... -
Physio-biochemical characterization of two wheat cultivars to Fusarium proliferatum infection
(University of the Western Cape, 2019)Wheat is a key global commodity in terms of acreage and tradeable value and as a staple in household diets. Many factors including biotic stress conditions have detrimental effects on global wheat production and yield. ... -
Physiological and biochemical characterization, of antimony stress, responses in Phaseolus vulgaris
(University of the Western Cape, 2018)The mining industry in South Africa is of immense importance as this sector contributes largely to the countries income. In the Limpopo province, a large production of antimony (Sb) is generated per year. Antimony (Sb) is ... -
Physiological and cellular characterization of a plant natriuretic peptide
(University of the Western Cape, 2005)Plants in the field are exposed to multiple stresses and their response to these various stresses determines their capacity to survive. Plants can use multiple signaling pathways and signals to mediate their response; for ... -
Physiological and molecular characterization of wheat cultivars to Fusarium oxysporum infection
(University of the Western Cape, 2019)Biotic stress is one of the main causes for agricultural loss of economically important cereal crops. The increasing prevalence of biotic stress inflicted by fungal species such as Fusarium has significantly reduced yields ... -
Phytochemical and antimicrobial studies on Rhus natalensis
(2011)Extracts from the root bark, stem bark, and leaves of R. natalensis were screened for antibacterial activity against standard bacterial strains; Staphylococcus aureas, Escherichia coli and Pseudomonas aureginosa, and fungi; ... -
