Comparison of cytokine and immunoglobulin levels in blood between asymptomatic serum sryptococcal antigen positive and negative HIV-positive individuals with CD4 counts <100 cells/ μl. A nested case-control study in Harare.
(University of Zimbabwe, 2021-06-09)
Background: Cryptococcosis is still a leading cause of mortality among patients with advanced HIV infection. Although CD4 T-cell deficiency is necessary for HIV-associated cryptococcosis, not all severely immunocompromised ...
Markers of inflammation, morbidity and mechanisms mediating resistance against Schistosoma haematobium infection in preschool age ahildren (Children aged five years and below).
(University of Zimbabwe, 2021-06-09)
Schistosomiasis is caused by a blood fluke worm of the genus Schistosoma. Adult worms can live for decades in the human host releasing ova causing inflammatory and obstructive disease in the urinary system. The preschool-age ...
Impact of climate change and biotic factors on avifauna diversity and spatial distribution in the mid-Zambezi Valley, Zimbabwe.
(University of Zimbabwe, 2021-06)
Construction of Lake Kariba on the Zambezi River restructured the biodiversity of the Zambezi Valley. However, studies on how the avian community of Kariba has changed since construction of the lake are scant. This study ...
The Taxonomy, ecology and trematode infections of gastropod snails on the northern shoreline of Lake Kariba, Zimbabwe.
(University of Zimbabwe, 2021-08)
Freshwater gastropods make up about 75% of all freshwater molluscs in the African continent. Their classification and identification have been largely based on morphological characteristics, with the main focus on shell ...
Development and characterization of food products from Parinari curatellifolia (Hacha or Chakata) fruit
(University of Zimbabwe, 2015-11)
Parinari curatellifolia fruit is consumed in its raw state or processed into food products in
rural areas during periods of food shortage. The purpose of the study was to determine the
physico-chemical properties of ...
Accumulation of potentially harmful elements in edible parts of vegetables grown on two different geological substrates in Zimbabwe.
(Elsevier, 2019-09-12)
This study investigated the bioaccumulation of potentially harmful elements (PHEs) in common, locally grown vegetables in Zimbabwean farmlands. The aim of the study was to compare PHE accumulation in vegetables grown on ...
Differential magnetometer method applied to measurement of geomagnetically induced currents in Southern African power networks
(AGU Publications, 2016-03-18)
Geomagnetically induced currents (GICs) in conductors connected to the Earth are driven by an electric field produced by a time-varying magnetic field linked to magnetospheric-ionospheric current perturbations during ...
Modeling geomagnetically induced currents in the South African power transmission network using the finite element method.
(AGU Publications, 2015-03-24)
Geomagnetically induced currents (GIC) are a result of time variations of the geomagnetic field,which induce a geoelectric field at the Earth’s surface. Geomagnetic perturbations are enhanced during adverse space weather ...
Upper Bounds on the Diameter of Bipartite and Triangle-Free Graphs with Prescribed Edge Connectivity
(HINDAWI, 2020-09-03)
Graph theory is used to study the mathematical structures of pairwise relations among objects. Mathematically, a pair G=(V,E) is a crisp graph, where V is a nonempty set and E is a relation on V[1]. -e order of a graph G ...
Assessing the role of climate change in Malaria transmission in Africa.
(HINDAWI, 2016-02-23)
The sensitivity of vector borne diseases like malaria to climate continues to raise considerable concern over the implications of climate change on future disease dynamics. The problem of malaria vectors shifting from their ...
