Photoluminescent Responses of Polypropylenethiophenoimine-Co-Pedot/ Polystyrenesulfonic Acid and Zinc Selenide Quantum Dot Composite Materials
(University of the Western Cape, 2018)Research in renewable energy has gained momentum and become a centre of attention as a possible alternative solution to the energy catastrophe. This is attained by the use of solar energy as an alternative clean energy ... -
A photometric soft-tissue profile assessment in a Western Cape sample
(Uiversity of the Western Cape, 1986)Cephalometric norms for the soft-tissue profile presently utilized in this country, are based almost entirely on North American Caucasian and Negroid studies. Orthodontists use these standards as a guide in the treatment ... -
Photophysics of Thiophenosalicylaldimine-functionalized G1-Polyprolyleniminato-Copper Telluride/Antimonide core-shell Nanomaterials
(University of the Western Cape, 2018)This work involves the synthesis of copper telluride-polypropylenimine tetra(5-(2-thienyl) salicylaldimine) (CuTe@PPI) and copper antimonide-polypropylenimine tetra(5-(2-thienyl) salicylaldimine) (CuSb@PPI) core-shell ... -
Photovoltaic and gas sensing applications of transitional metal nanocomposites of poly(3-hexylthiophene)-titanium dioxide
(University of Western Cape, 2021)This thesis starts with the reviewing of studies on the loading of noble metals and nanostructured metal oxides into bulk heterojunction organic solar cell device architectures. The reviews focused on the innovative ... -
Photovoltaics of novel samarium and terbium doped caesium gallium iodobromide hollow-nanocrystals perovskite
(University of the Western Cape, 2022)Perovskite solar cells have recently piqued the scientific community's interest due to their outstanding performance, which has seen them achieve up to 25% power conversion efficiency (PCE) after just 7 to 8 years of ... -
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 activity after spinal cord injury: exploring experiences in the Cape Metropolitan area
(The University of the Western Cape, 2017)A spinal cord injury (SCI) is an acquired injury, by which damage to the spinal cord causes complete or partial neurological impairment. The major causes of premature death after a spinal cord injury have been documented ... -
Physical activity and non-communicable disease risk factors: knowledge and perceptions of youth in a low resourced community in the Western Cape
(University of the Western Cape, 2019)The prevalence of non-communicable diseases (NCDs) are the rising cause of mortality globally. Physical inactivity, unhealthy diet, tobacco use, and excessive alcohol consumption are common NCDs risk factors contributing ... -
Physical activity behaviours of persons with HIV and AIDS in low-income populations: The design of a context-sensitive randomised control trial
(University of the Western Cape, 2018)The Human immunodeficiency virus (HIV) and acquired Immunodeficiency syndrome (AIDS) are serious health issues that continue to affect many nations. Specifically, the sub-Saharan African region has the highest prevalence ... -
Physical activity levels among people living with HIV/AIDS treated with high active antiretroviral therapy in Rwanda
(University of the Western Cape, 2011)The use of high active antiretroviral therapy in people living with HIV/AIDS is increasing worldwide. In Rwanda, above 70 % of people in need of antiretroviral therapies is getting them. This drug therapy is associated ... -
Physical activity levels and health promotion strategies among physiotherapists in Rwanda
(University of the Western Cape, 2011)Physical inactivity has become a global health concern and is among the 10 leading causes of death and disability. This has led to increased concern for chronic diseases of lifestyle (CDL). Studies have revealed that regular ... -
