(2012-08-29)Multimedia transmission over communication networks has been growing rapidly with respect to the number of users and the amount and type of traffic. Wireless communications are a fast emerging technology and have become ... -
Determination of lymphocyte and cytokine profiles associated with Coronavirus disease 2019 severity
(2021-07)Coronavirus disease 2019 (COVID-19) is caused by a recently identified virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the disease is a pandemic. Recurrent waves of infection continue to overwhelm ... -
Determination Of Nitrogen And Sulphur Oxides Produced During Combustion Of Jatropha Cake Bio-Pellet
(2013-09-25)Jatropha cake is a promising renewable source of energy, its use as a combustible fuel makes it an important source of potentially harmful gases to the environment and the health of the users. It is important to determine ... -
Determination of platinum, palladium, rhodium and gold in ores and concentrates using iridium and ruthenium as co-collectors by fire assay
(2016-04)Determination of platinum group metals (PGMs) and gold also known as precious metals is always a very difficult task, this is due to their availability in trace amounts in sample types of complex composition. Little research ... -
Determination of water productivity of maize varieties grown in Zimbabwe
(2012-09-12)The quantification of water use in plants is necessary to maximize water use efficiency in semi -arid areas where water is often limiting. The main objective of the study was to quantify maize water productivity and apply ... -
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 ... -
Development of irrigation guidelines for citrus under drip irrigation in Zimbabwe
(2012-09-13)This study was carried out to develop drip irrigation guidelines for citrus in Zimbabwe. In order to achieve this, the average ETo values for the study site were derived from climatic data. The study, which was carried out ... -
Differentiations in post-colonial urban spatial planning in Zimbabwe and Zambia
(2021-01)This study investigates and compares the colonial spatial planning legacies of Zimbabwe and Zambia. It examines how and why the legacies of two countries with a seemingly common colonial background would produce different ... -
Distance measures in graphs
(2016-10)This thesis details the results of an investigation of bounds on four distances measures, namely, radius, diameter, the Gutman index and the edge-Wiener index, in terms of other graph parameters, namely, order, irregularity ... -
Distributed deadlocks in distributed databases
(2012-08-29)The developments of database management system (DBMS) technology has run in parallel with the developments in computer networks and distributed computing technologies. Consequently there is the birth of distributed ... -
Distribution modelling of Leptocybe Invasa (Hymenoptera: Eulophidae), and an assessment of host susceptibility and relative efficacies of systemic insecticides for gum seedling protection in Zimbabwe
(2017-11-16)Studies were conducted from February 2015 to December 2015 to predict the potential distribution of the blue gum chalcid or Eucalyptus gall wasp, Leptocybe invasa Fisher and La Salle in Zimbabwe, to screen locally available ... -

(2016)Studies were conducted from February 2015 to December 2015 to predict the potential distribution of the blue gum chalcid or Eucalyptus gall wasp, Leptocybe invasa Fisher and La Salle in Zimbabwe, to screen locally available ... -
The distribution of cattle and their interaction with the African Buffalo at the wildlife-livestock interface understood using real-time Global Positioning Systems (GPS) and remotely sensed data
(2016-04)The distribution of herbivores is hypothesized to be influenced by an interplay of several biophysical factors as well as human factors. However, our current understanding of herbivore movement dynamics and factors driving ... -
Diverse Antigen-specific Antibody and Atopic Responses In Schistosomiasis and Malaria Co-infected Individuals.
(2016-04)The study was part of a huge schistosomiasis survey investigating schistosomiasis in the human model and was conducted in the Mashonaland East Province of Zimbabwe (31o 30‘E; 17o 45‘S) at Magaya and Chitate schools where ... -
Diversity and population dynamics of bactrocera invadens and other tephritid fruit fly species infesting mango (mangifera indica) in Zimbabwe and relative efficacies of selected insecticides incorporated in food baits
(2016-04)Studies were conducted from November 2013 to October 2014 in Zimbabwe to determine the temporal population dynamics of the invasive fruit fly pest Bactrocera invadens (Diptera: Tephritidae), to determine the pest’s host ... -
Diversity patterns and host shifts in ectomycorrhizal fungi across an agricultural disturbance gradient in the mid-Zambezi area, Zimbabwe
(2016-11)Fallowing creates land mosaics characterised by vegetation communities at different stages of succession. Such mosaics are expected to harbour mycorrhizal associations that reflect host species composition and diversity. ... -
Effect of duration of early-age thermal conditioning of broiler chickens on production and heat tolerance
(2012-09-12)The main objective of the study was to investigate the appropriate duration of early age thermal conditioning that would improve heat tolerance in broiler chickens with a minimum reduction in production performance. 200 ...
