Factors Affecting The Growth Of Sheep And Goats In Africa
(University of Nairobi, 1985)Phenotypic weight of mature females from a representative sample of African environments range from 30-45 kg for ewes and from 20-35 kg for does. Growth rates for the same sample range from 75-140 g/day for lambs and 50-100 ... -
The incidence of Brucella ovis in some Kenya flocks and its relationship to clinical lesions and semen quality.
(University of Nairobi, 1971)Three flocks (all Romney Marsh) out of 13 were found to be infected, suggesting the disease had been introduced through sheep importations from New Zealand. A study of clinical lesions in the genital tract and of seminal ... -
Source apportionment and seasonal variation of PM2.5 in a Sub-Sahara African city: Nairobi, Kenya
(University of Nairobi, 2014)Sources of airborne particulate matter and their seasonal variation in urban areas in Sub-Sahara Africa are poorly understood due to lack of long-term measurement data. In view of this, airborne fine particles matter ... -
Growth and regeneration of plantlets in callus cultures of pineapple
(University of Nairobi, 1981-03)Callus cultures were established from the basal region of in vitro-obtained shoot buds on MS medium supplemented with CH + CW + NAA. Such callus cultures, when grown on MS medium devoid of any growth regulators, regenerated ... -
Multiple Plantlets In Lateral Bud And Leaf Explant In Vitro Cultures Of Pineapple
(University of Nairobi, 1979-12)Plantlets were obtained from usually dormant axillary buds, excised from the crown of pineapple (Ananas comosus L. Merr.) and grown in culture. Multiple shoots arose from single buds grown on Murashige and Skoog medium ... -
Measuring fecal testosterone in females and fecal estrogens in males: comparison of RIA and LC/MS/MS methods for wild baboons (Papio cynocephalus)
(University of Nairobi, 2014-05)The development of non-invasive methods, particularly fecal determination, has made possible the assessment of hormone concentrations in wild animal populations. However, measuring fecal metabolites needs careful validation ... -
In Vitro Clonal Multiplication Of Pyrethrum (Chrysanthemum Cinerariaefolium Vis.) By Micropropagation
(University of Nairobi, 1981-09)Successful tissue culture procedures have been established for rapid in vitro multiplication of pyrethrum. Multiple shoot formation through axillary bud proliferation was induced in shoot tip cultures on Murashige & Skoog's ... -
Random Chromosome Breakage By Colchicine Inviscum Fischeri (Loranthaceae)
(University of Nairobi, 1978)When the shoot-tips ofViscum fischeri Engl. were treated with various concentrations of colchicine for different lengths of time, it was found that in this plant chromosome breakage was not localized to centromeric region ... -
A Prospective Cohort Study of the Effect of Depot Medroxyprogesterone Acetate on Detection of Plasma and Cervical HIV-1 in Women Initiating and Continuing Antiretroviral Therapy
(University of Nairobi, 2014-05)Depot medroxyprogesterone acetate (DMPA) use among HIV-1 infected women may increase transmission by increasing plasma and genital HIV-1 RNA shedding. We investigated associations between DMPA use and HIV-1 RNA in plasma ... -
Photosynthetic Systems As A Basis For Weed Competition
(University of Nairobi, 1980)The characteristics of the major pathways of CO2 fixation (C3 and C4) and their relevance to plant competition in E. Africa is discussed. Most of the C3 species are found in the highlands whereas the C4 species are restricted ... -
Gas Exchange Of Finger Millet Inflorescences
(University of Nairobi, 1978)The growth and development of finger millet [Eleusine coracana (L.) Gaertn.] inflorescences is described. The respiration rate on a dry weight basis remained uniform until it decreased during the later stages of seed filling ... -
Mineral Element Content of Some Benthic Marine Algae of the Kenya Coast
(University of Nairobi, 1972) -
Effect of Atrazine on Physiological Processes in Leaves
(University of Nairobi, 1971)We fed 2-chloro-4-(ethylamino)-6-(isopropylamino-s-triazine (atrazine) through the base of excised leaves of atrazine-tolerant and -susceptible species. Atrazine suppressed CO2 uptake in all species. This was shown to be ... -
Response of Cowpeas to Salinity and (2-Chloroethyl) trimethyl-ammonium Chloride (CCC)
(University of Nairobi, 1973-04)Recent investigations have demonstrated that the growth retardant, (2-chloroethyl) trimethyl-ammonium chloride (CCC) inhibits several aspects of vegetative growth. In solution culture experiments, reduction in plant growth ... -
Influence Of Light And Temperature On Photosynthesis And Transpiration In Some C3 And C4 Vegetable Plants From Kenya
(University of Nairobi, 1977-04)Potted vegetable plants of Amaranthus lividus, Gynandropsis gynandra and Crotalaria brevidens were grown outside under normal tropical conditions and rate of photosynthesis and transpiration were determined simultaneously ... -
Photosynthetic Systems, Carbon Isotope Discrimination And Herbivore Selectivity In Kenya
(University of Nairobi, 1980-10)The flora of the lowlands of East Africa possesses both C3 and C4 plants with nearly all grasses being C4. These photosynthetic systems discriminate differently against 13C. We have utilized the ‘label’ provided by the ... -
Biomass Dynamics Of Grassland Vegetation In Kenya
(University of Nairobi, 1988-06)Seasonal changes in plant biomass in the herb layer were measured at Nairobi National Park and Masai Mara Game Reserve in Kenya from January 1980 to February 1981. Plant biomass fluctuated in response to seasonal rainfall, ... -
Seasonal Changes In The Nutrient Content Of East African Grassland Vegetation
(University of Nairobi, 1988-06)Significant seasonal changes in the concentrations of N, P, K, and Ca were observed in the herb layer vegetation at Nairobi National Park and Masai Mara Game Reserve in Kenya. These changes were related to the alternation ... -
