Biologically directed environmental monitoring, fate, and transport of estrogenic endocrine disrupting compounds in water: A review
(Elsevier Publications, 2006)Endocrine disrupting compounds (EDCs) are contaminants that may be hormonally active at low concentrations and are emerging as a major concern for water quality. Estrogenic EDCs (e-EDCs) are a subclass of EDCs that, when ... -
Detecting estrogenic activity in water samples with estrogen-sensitive yeast cells using spectrophotometry and fluorescence microscopy
(2006-03)Environmental estrogens are environmental contaminants that can mimic the biological activities of the female hormone estrogen in the endocrine system, i.e. they act as endocrine disrupters. Several substances are reported ... -
Developing a yeast-based assay protocol to monitor total oestrogenic activity induced by 17β-oestradiol in activated sludge supernatants from batch experiments
(Lawrence Berkeley National Laboratory, 2006-04-11)A yeast-based assay protocol developed for detecting oestrogenic activity in activated sludge (AS) supernatant is described. The protocol used Saccharomyces cerevisiae construct RMY/ER-ERE with human oestrogen receptor ... -
Application of a yeast-based assay protocol developed to monitor total oestrogenic activity induced by 17β-oestradiol in activated sludge supernatants from batch experiments
(Lawrence Berkeley National Laboratory, 2006-04-11)Batch experiments were carried out with activated sludge from laboratory reactors and a full-scale treatment plant spiked with 17β-oestradiol (E2). An oestrogen-sensitive yeast-based assay protocol, described in detail in ... -
Rapid water sample screening for estrogenic activity using live yeast cells
(2007)Endocrine disrupting compounds (EDCs) are substances that influence the endocrine system in living organisms. They include natural hormones, medicinal drugs, chemical compounds in industry, and pesticides in agriculture. ... -
Computational identification of transposable elements in the mouse genome
(2007)Repeat sequences cover about 39 percent of the mouse genome and completion of sequencing of the mouse genome [1] has enabled extensive research on the role of repeat sequences in mammalian genomics. This research covers ... -
Real-Time Molecular Monitoring of Chemical Environment in Obligate Anaerobes during Oxygen Adaptive Response
(California Digital Library, University of California, 2009-08-26)Determining the transient chemical properties of the intracellular environment can elucidate the paths through which a biological system adapts to changes in its environment, for example, the mechanisms which enable some ... -
Analysis of persistence soil nutrient status in abandoned cattle kraals in a semi arid area in Botswana
(2010-12)The aim of this study was to analyze the depletion of soil nutrients with time on abandoned kraals in a peri-urban area of Botswana. Active kraals are enriched with nutrients through the accumulation of animal droppings ... -
Investigating water meter performance in developing countries: A case study of Kampala, Uganda
(2011)High levels of water losses in distribution systems are the main challenge that water utilities in developing countries currently face. The water meter is an essential tool for both the utility and the customers to measure ... -
Herbaceous and Woody Plant Properties in Abandoned Kraal Areas in a Hardveld Botswana
(2011)Herbaceous and woody plant species in abandoned traditional kraals were investigated. To achieve the aim of this study, nutrient status of soil in addition to vegetation composition and communities from the kraal sites ... -
Effect of the transposable element environment of human genes on gene length and expression
(Oxford University Press, 2011-02-28)Independent lines of investigation have documented effects of both transposable elements (TEs) and gene length (GL) on gene expression. However, TE gene fractions are highly correlated with GL, suggesting that they cannot ... -
Assessment of apparent losses in urban water systems
(2011-08-17)Apparent losses relate to water that is consumed but not paid for. Most research carried out in the last decade particularly in the United Kingdom focused mainly on leakage. Until now, there are no set procedures and ... -
Pore pressure development in hybrid fibre – reinforced high strength concrete at elevated temperatures
(2011-11)The present experimental work investigates the build – up of pore pressure at different depths of High Strength Concrete (HSC) and Hybrid-Fibre-Reinforced High Strength Concrete (HFRHSC) when exposed to different heating ... -
Multi-criteria Decision Analysis: A Strategic Planning Tool for Water Loss Management
(2011-11)Water utilities particularly in the developing countries continue to operate with considerable inefficiencies in terms of water and revenue losses. With increasing water demand and scarcity, utilities require effective ... -
Prediction of transposable element derived enhancers using chromatin modification profiles
(PLoS ONE (Public Library of Science), 2011-11-07)Experimentally characterized enhancer regions have previously been shown to display specific patterns of enrichment for several different histone modifications. We modelled these enhancer chromatin profiles in the human ... -
On the presence and role of human gene-body DNA methylation
(International Multidisciplinary Publishing Academy for Computational Technologies, 2012-05-09)DNA methylation of promoter sequences is a repressive epigenetic mark that down-regulates gene expression. However, DNA methylation is more prevalent within gene-bodies than seen for promoters, and gene-body methylation ... -
Reverse Logistics Related to Waste Management with Emphasis on Developing Countries—A Review Paper
(2012-09-20)This paper provides an overview of the state of art of reverse logistics and current status of waste management problems with special emphasis on developing countries. Logistics activities have been practiced and played a ... -
Prediction of fire spalling in fibre-reinforced high strength concrete
(2013)This paper presents results of a study which investigates spalling in small scale specimens of fibre-reinforced high strength concrete exposed to elevated temperatures. A relationship to predict relative maximum pressures ... -
Calibrating an optimal condition model for solar water disinfection in peri-urban household water treatment in Kampala, Uganda
(IWA Publishing, 2013)In low income settlements where the quality of drinking water is highly contaminated due to poor hygienic practices at community and household levels, there is need for appropriate, simple, affordable and environmentally ... -
Factors influencing selection of drinking water technologies for urban informal settlements in Kampala
(2013-08-12)Access to drinking water in urban informal settlements of developing countries still remains a challenge for the poor and depends on technology selected. This paper determines the score on criteria used for technology ...
