Optimum conditions for microbial carbonate precipitation

Okwadha, George (2015-09-02)

The type of bacteria, bacterial cell concentration, initial urea concentration, reaction temperature, the initial Ca2+ concentration, ionic strength, and the pH of the media are some factors that control the activity of ...
Biocontainment of polychlorinated biphenyls (PCBs) on flat concrete surfaces by microbial carbonate precipitation

Okwadha, George (2015-09-02)

In this study, a biosealant obtained from microbial carbonate precipitation (MCP) was evaluated as an alternative to an epoxy-coating system. A bacterium Sporosarcina pasteurii strain ATCC 11859, which metabolizes urea and ...
Thermal Removal of Mercury in Spent Powdered Activated Carbon from TOXECON Process

Okwadha, George (2015-09-02)

This research developed and demonstrated a technology to liberate Hg adsorbed onto powdered activated carbon PAC by the TOXECON process using pilot-scale high temperature air slide HTAS and bench-scale thermogravimetric ...
Evaluation of Surface Water Runoff from Fly Ash–Stabilized and Nonstabilized Soil Surfaces

Okwadha, George (2015-09-02)

This study evaluated the constituent make up of simulated rainwater runoff from Class C fly ash–stabilized and nonstabilized clay soil using laboratory test pads to assess the potential for impacts to surface water from ...
Spatial Modelling of Solar Energy Potential in Kenya

Oloo Francis; Olang, Luke; Strobl, Josef (2017-09-27)

Solar energy is one of the readily available renewable energy resources in the developing countries within the tropical region. Kenya is one of the countries which receive an average of approximately 6.5 sunshine hours in ...
Institutional challenges in scaling-up climate change adaptation actions: experiences from rural communities in Senegal and Kenya

Olang, Luke O.; Ouma, Gilbert O.; Dieye, Amadou M.; Ogallo, Laban O. (2017-09-27)

Regional institutions in Africa have the potential to reinforce the adaptive capacity of rural communities in handling climate change impacts. The institutional arrangements provide the rationale for scaling-up adaptation ...
