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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Extent, rate of invasion and conditions favouring occupancy and dominance of typha latifolia in selected wetlands of Harare, Zimbabwe.
(University of Zimbabwe, 2019)Typha latifolia is a global aggressive invader of wetlands. It is now one of the major threats to wetland ecosystems in Harare. Factors that promote its establishment and dominance are still poorly understood. The present ... -
Modelling the effects of behavioral change on the transmission dynamics of Herpes Simplex Virus Type 2 (HSV-2).
(2017-10-13)Herpes simplex virus type 2 (HSV-2) is the most prevalent sexually transmitted disease worldwide, despite the availability of highly effective anti-viral treatment. It is of great concern that as other sexually transmitted ... -
Evaluation of the antimycobacterial properties of plant extracts from Vernonia adoensis.
(University of Zimbabwe, 2019-10)Tuberculosis (TB), is a mycobacterial infection resulting from Mycobacterium uberculosis. Two million individuals die annually due to TB and currently, treating this infection is a massive challenge owing to the emergence ... -
Immuno-epidemiology of helicobacter pylori-associated autoimmune conditions in Zimbabwean patients.
(University of Zimbabwe, 2019-10)The bacterium Helicobacter pylori (H. pylori) colonizes the human gastric mucosa and is a recognized causative agent for peptic ulcer disease. The prevalence of H. pylori infection in Zimbabwe is unknown. Treatment requires ... -
Characterisation pollen allergens in Zimbabwe of grass.
(University of Zimbabwe, 2018)IgE mediated hypersensitivity affects more than 25% of the industrialized countries. The first wave was that of inhalant allergies and this has been recorded as a series of ISAAC studies. The second wave is emerging and ... -
Modelling gender differences in drug abuse epidemics.
(Springer, 2018-01-11)Drug abuse is an issue of considerable concern due to its association with numerous public health problems. Mathematical models developed to describe the spread of drug abuse have generally assumed that the dynamics of ... -
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 ... -
Transmission dynamics of schistosomiasis in Zimbabwe: A mathematical and GIS approach.
(Elsevier, 2015-11-15)Temperature and presence of water bodies are known to influence the transmission dynamics of schistosomiasis. In this work, effects of water bodies (taken in context of rainfall patterns)and temperature from 1950 to 2000 ... -
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 ... -
Assessing the impact of drug resistance on the transmission dynamics of Typhoid fever.
(Hindawi, 2013-05-20)Typhoid fever continues to be a major public health problem in the developing world. Antibiotic therapy has been the main stay of treating typhoid fever for decades. The emergence of drug-resistant typhoid strain in the ... -
Modeling gonorrhea and HIV co-interaction.
(Elsevier, 2010-09-14)A mathematical model was designed to explore the co-interaction of gonorrhea and HIV in the presence of antiretroviral therapy and gonorrhea treatment. Qualitative and comprehensive mathematical techniques have been used ... -
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 ... -
An Upper Bound on the Radius of a 3-Vertex-Connected C4-Free Graph
(HINDAWI, 2020-08-04)Let G=(V,E) be a finite, connected, undirected graph with vertex set V and edge set E. -e distance dG (u,v) between two vertices u, v of G is the length of a shortest u-v path in G.-e eccentricity ec(v)of a vertex v∈V is ... -
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 ...
