Ecological, socio-economic and livelihood differentiation of Kenya’s Lembus forest proximate communities: The case of the Tugen and Lembus. Anthropologist
(2009)The Tugen and Lembus are indigenous communities found adjacent to the Lembus igenous forests. Other than these two communities, there are several others inhabiting this area the surrounding districts. The Lembus igenous ... -
Efficacy of the novel diamidine compound 2,5-Bis(4-amidinophenyl)- furan-bis-O-Methlylamidoxime (Pafuramidine, DB289) against Trypanosoma brucei rhodesiense infection in vervet monkeys after oral administration
(American Society for Microbiology, 2009)10 to 30 days to facilitate treatment with parenterally administered medicines. The efficacy of a novel orally administered prodrug, 2,5-bis(4-amidinophenyl)-furan-bis-O-methlylamidoxime (pafuramidine, DB289), was tested ... -
Nodulation and nitrogen fixation in promiscuous and non promiscuous soybean (Glycine max (L.) Merrill) varieties in Eastern Kenya
(Kenya Society of Microbiology, 2010)Soil nitrogen deficiency is a major factor limiting soybean production. This problem can be alleviated by the use of nitrogen fertilizers which on the other hand adversely affect the environment, are expensive and ... -
Evaluating the macropropagation efficiency of banana varieties preferred by farmers in Eastern and Central Kenya
(Kenya Agricultural Research Institute, 2010)Kenyan farmers are threatened by overreliance on few crops whose yields are reduced by adverse climatic changes. Bananas are more resilient and produce year round, making it a more suitable crop. To increase banana production, ... -
Biological nitrogen fixation by promiscuous soybean (Glycine max L. Merril) in the central highlands of Kenya: response to inorganic fertilizer soil amendments.
(IDOSI Publications, 2010)Biological nitrogen fixation (BNF) by promiscuous soybean cultivars offers a potential for minimizing the investment made by resource-limited farmers in central highlands of Kenya. Nitrogen fixation in this grain legume ... -
Cassava production and limitation of propagation through tissue culture
(Contribution of Agricultural Sciences towards achieving the Millenium Development Goals, 2010)With the unrelenting increase in human population it is important that concerted efforts be made to increase crop productivity so as to match the expected increase in food demand. The gravity of this problem is well ... -
Low technology tissue culture materials for initiation and multiplication of banana plants
(African Crop Science Society (Uganda), 2010)Tissue culturing has become a routine method for propagating plants in high technology laboratories. The cost of production using conventional tissue culture is, however, high for most of the countries in the sub-Saharan ... -
Development of an Acoustic Measurement System for Analyzing Crispiness during Mechanical and Sensory Testing
(Wiley, 2010)The objective of this study was to develop an acoustic measurement system for analyzing crispiness and correlate its results with sensory evaluation. Four biscuits (Crackerbread, Table Water, Rich Tea and Shortbread) were ... -
Effect of Water Activity on the Crispiness of a Biscuit (Crackerbread): Mechanical and Acoustic Evaluation
(Elsevier, 2010)The objective of this study was to use mechanical and acoustic methods developed in our laboratory to monitor the changes in crispiness of a Crackerbread biscuit following equilibration at different water activities (aw). ... -
Diamidines for human African trypanosomiasis
(Thomson Reuters, 2010)Aromatic diamidines are potent trypanocides. Pentamidine, a diamidine, has been used for more than 60 years to treat human African trypanosomiasis (HAT); however, the drug must be administered parenterally and is active ... -
Characterization of ethylene biosynthesis and its regulation during fruit ripening in kiwifruit, Actinidia chinensis ‘Sanuki Gold’
(Elsevier, 2010)Ethylene biosynthesis in kiwifruit, Actinidia chinensis ‘Sanuki Gold’ was characterized using propylene, an ethylene analog, and 1-methylcyclopropene (1-MCP), an inhibitor of ethylene perception. In fruit harvested between ... -
Simulating Hybrid-seed Contamination Risk with Selfed Seeds from Residual Fertility in a Male-sterile T-4 Mutant Tomato, Solanum lycopersicum L.
(Journal of the Japanese Society for Horticultural Science, 2010)Environmental dependence of male sterility may sometimes result in residual fertility under ‘sterility conditions’, causing hybrid-seed contamination risk. An experiment was conducted to assess the risk factor and methods ... -
Response of leaf yield and nutritive value of African nightshade (Solanum Villosum) genotypes to nitrogen application
(African Journal of Horticultural Science, 2010-12)The wild-type Solanumu villosum is an important leafy vegetable in Kenya, which however is low-yielding mainly due to the early flowering and prolific fruiting. Two new genotypes of S. villosum, T-5 and octoploid with ... -
Low-temperature-modulated fruit ripening is independent of ethylene in ‘Sanuki Gold’ kiwifruit
(Journal of Experimental Botany, 2011)Fruit ripening in response to treatments with propylene, 1-methycyclopropene (1-MCP), and low temperature was characterized in ‘Sanuki Gold’ kiwifruit,Actinidia chinensis Planch. Propylene treatment immediately induced ... -
Differential effects of various African nightshade species on the fecundity and movement of Tetranychus evansi (Acari: Tetranychidae)
(Cambridge University Press, 2011)The tomato red spider mite Tetranychus evansi Baker & Pritchard is a serious pest of solanaceous plants worldwide. Management of this oligophagous pest in African nightshades has been a challenge to smallholder ... -
Echinococcosis in sub-Saharan Africa: emerging complexity
(Elsevier, 2011)Cystic echinococcosis occurs in most regions of sub-Saharan Africa, but the frequency of this zoonosis differs considerably among and within countries. Especially human cases seem to be focally distributed. A number of ... -
