Estimating pedestrian accident risk using conflict techniques and digital imaging.
(2003)Accidents are a complex process involving many contributory factors. The understanding of the accident process has often been sought by the use of accident data. Although accident data provide a direct relationship to ... -
Estimating risk determinants of HIV and TB in South Africa.
(2009)Where HIV/AIDS has had its greatest adverse impact is on TB. People with TB that are infected with HIV are at increased risk of dying from TB than HIV. TB is the leading cause of death in HIV individuals in South Africa. ... -
Estimating solar radiation for water-use and yield simulations under present and projected future climate using Cropsyst.
(2003)Agricultural scientists are faced with the challenge of producing enough food for the increasing world population. Hence the need to develop tools for managing soil and plant systems to increase food production in order ... -
Estimating the force of infection from prevalence data : infectious disease modelling.
(2013)By knowing the incidence of an infectious disease, we can ascertain the high risk factors of the disease as well as the e ectiveness of awareness programmes and treatment strategies. Since the work of Hugo Muench in 1934, ... -
Estimating the relationship between informal sector employment and formal sector employment in selected African countries.
(2010)Very little research evidence exists with respect to the informal sector in African countries. Although (mixed) theoretical evidence does exist that postulates a relationship between formal sector employment and informal ... -
Estimating traffic induced sugarcane losses for various harvesting, loading and infield transport operations in South Africa.
(2016)Infield traffic has been understood to cause adverse field conditions for crop growth. Literature containing traffic induced yield responses for sugarcane was reviewed and synthesised to better estimate the impact of infield ... -
Estimating water use and yield of soybean (glycine max) under mulch and fertilizer in rainfed conditions in KwaZulu-Natal.
(2017)South Africa is classified as a semi-arid country characterized by low and erratic rainfall. This poses major limitations to crop productivity, especially for smallholder farmers who rely on rainfed agriculture. This is ... -
Estimating woody vegetation cover in an African Savanna using remote sensing and geostatistics.
(2008)A major challenge in savanna rangeland studies is estimating woody vegetation cover and densities over large areas where field based census alone is impractical. It is therefore crucial that the management and conservation ... -
Estimation and analysis of measures of disease for HIV infection in childbearing women using serial seroprevalence data.
(2011)The prevalence and the incidence are two primary epidemiological parameters in infectious disease modelling. The incidence is also closely related to the force of infection or the hazard of infection in survival ... -
Estimation of carcass composition of beef cattle by the urea dilution technique.
(1977)No abstract available. -
Estimation of catchment response time in medium to large catchment in South Africa.
Abstract and extended abstract available in the print copy. -
-
The estimation of Eucalyptus plantation forest structural attributes using medium and high spatial resolution satellite imagery.
(2008)Sustaining the socioeconomic and ecological benefits of South African plantation forests is challenging. A more systematic and rapid forest inventory system is required by forest managers. This study investigates the utility ... -
Estimation of genetic and demographic parameters of extensively raised chicken populations using genome-wide single nucleotides polymorphism (SNP) data.
(2015)Village chicken populations are raised under a farming system that faces a number of challenges such as small flock size, lack of animal performance and pedigree records, lack of proper husbandry and poorly defined and ... -
Estimation of genetic variation and marker identification in black wattle (Acacia mearnsii De Wild) with RAPD fingerprinting.
(2013-11-15)No abstract available. -
Estimation of hydrological properties of South African soils.
(1983)A computer simulation model of the soil water regime can be a useful research, planning and management tool, providing that the data required by the model are available. Finite difference solutions of the general flow ... -
The estimation of landfill gas emissions in the Durban Metropolitan Area (DMA) using the LANDGEM model.
(2001)Landfill gas (LFG) contributes significantly to air pollution. Methane (CH4) and carbon dioxide (CO2) are the major constituents of LFG, and are significant greenhouse gases that play a vital role in causing global ... -
Estimation of reference evaporation and comparison with ET-gage evaporimeter
(2003)Accurate estimation of reference evaporation is necessary for the estimation of actual evaporation for irrigation and water resource management purposes. Estimation of reference evaporati~n using the Penman-Monteith method ... -
Estimation of the hydrological response to invasive alien plants in the upper Blyde River catchment.
(2003)The change in total evaporation through alteration of vegetative cover is a major influence on catchment hydrology. The transformation of grassland and scrub habitats to commercial tree plantations, as well as the uncontrolled ...
