Lead and other metals distribution in local cooking salt from the fofi salt‐ spring in akwana, middle benue trough, Nigeria
(1991)
Energy Dispersive X‐ray Fluorescence(EDXRF) technique has been used to determine the concentrations of lead(Pb) and other heavy metals in local cooking salts(LCS) from Akwana village, Middle Benue Trough, Nigeria. The ...
The impact of pollution on the ecology of the Nairobi-Athi River system in Kenya
(1991)
The pollution of the Nairobi-Athi River System is assessed by heavy metal analysis of the river water, industrial effluents, the invertebrate community and the riverine vegetation between Nongara upstream (UP) and 14 falls. ...

Biogas technology for rural households in Kenya
(1997)
Less than 20% of Kenya's population is connected to the grid. Only 5% of the country's rural population, which accounts for over 70% of the total population enjoys electricity connectivity. To compensate for this deficiency ...
Optimal Real and Reactive Power Control Using Linear Programming
(1992)
This paper develops an improved real and reactive power control technique using linear programming (LP) for an integrated power system. The problem is decomposed into two subproblems comprising real (P) and reactive power ...
Ultra-High Strain Ceramics with Multiple Field-Induced Phase Transitions
(1994)
The induced polarization and longitudinal strain behavior of lanthanum- and titanium-modified antiferroelectric lead zirconate ceramics were measured as functions of electric field as high as 30 kV/mrn (300 kV/cm). Two ...
Optimal Long-term Reactive Power Planning Using Decomposition Techniques
(1991)
This paper is to solve an optimal long-term reactive power planning problem. The long-term planning problem is decomposed into three levels using three decomposition techniques. First, the multiyear planning problem is ...
