Influence of Legal Requirements on Environmental Concern and sustainability Practices in Small and Medium-size Manufacturing Enterprises in Nairobi, Kenya.
(Journal of Environment and Earth Science, 2015)Until recently it has been too easy to overlook Small and Medium-size Enterprises in the analysis of environmental impact of particularly the manufacturing sector (ibid 2003). SMEs continue to grow, so do their environmental ... -
Disparity between Leaf and Root Symptoms and Crop Losses Associated with Cassava Brown Streak Disease in Four Countries in Eastern Africa
(Journal of phytopathology, 2015)Cassava brown streak disease is endemic to the coastal regions of East Africa, and from around 2004, the disease resurged and became epidemic in the Great Lakes Region, where it continues to spread. In both these areas, ... -
Larviciding Potency of Water and Ethanol Extracts of Phytolacca dodecandra (L’ Herit) on Anopheles gambiae (Diptera: Culicidae)
(Mosquito Research, 2015)Introduction: Plant extracts are an attractive target for search of effective malaria vector control agents. The reason for this is that they present a cost effective, target specific and bio-degradable insecticides. The ... -
