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 ... -
Primary Productivity Of Natural Grass Ecosystems Of The Tropics: A Reappraisal
(University of Nairobi, 1989-04)Studies of net primary production in four contrasting tropical grasslands show that when full account is taken of losses of plant organs above- and below-ground these ecosystems are far more productive than earlier suggested. ... -
Use of δ13C values to determine vegetation selectivity in East African herbivores
(University of Nairobi, 1979)The quantitative plant species composition of the rumen contents of a large number of individuals from eight East African herbivores was determined by direct visual analysis. All plant species were classified as either C3 ... -
The Distribution Of C3 And C4 Grasses And Carbon Isotope Discrimination Along An Altitudinal And Moisture Gradient In Kenya
(University of Nairobi, 1979)More than 500 species of the Poaceae are found in Kenya, East Africa. Eighteen of twenty-seven tribes are exclusively (except the Paniceae and Danthonieae) of the C3 photosynthetic type. A floristic analysis of low altitude ... -
Chapter 10 – Renewable Energy Resources in Kenya
(University of Nairobi, 2013)Energy is an important input in a country's development process since it provides the stimulus, drive and momentum for socioeconomic development. It forms one of the foundations on which the three key pillars of the Kenya ... -
Chapter 1 – General Geology of Kenya
(University of Nairobi, 2013)The oldest supracrustal rocks in Kenya are the Archaean Nyanzian meta-volcanics and the Kavirondian meta-sediments. These rocks are found to the west of the country in the areas adjacent to Lake Victoria. The Neo-Proterozoic ... -
Information Systems strategy and Implementation: a case study of a building society.
(University of Nairobi, 1994-04-02)The formation and implementation of strategy with respect to computer-based information systems (IS) are important issues in many contemporary organizations, including those in the financial services sector. This paper ... -
Remote Sensing Techniques for Rapid detection of Soil Physical Degradatio. International Journal of Remote Sensing
(University of Nairobi, 2007-10)Physical degradation undermines soils' ability to perform their many biophysical functions. Currently, there is lack of rapid methods to facilitate timely large‐area assessment for effective control of the degradation. ... -
Experts Address The Question: How Has The Globalization Of Industrial Supply Chains Impacted Sustainable Development In Developing Countries?
(University of Nairobi, 2007-02)Sustainability reveals the effects of how we consumers use, renew, and account for environmental capital. Supply chains enable consumers to have access to high quality products and services at the lowest possible cost. A ... -
Method for Discovering Broken Symmetries from Experimental Scattering Data
(University of Nairobi, 1982)A method based on a modified eigenchannel formalism is proposed for discovering broken symmetries from experimental coupled-channel scattering data. The method suggests that the low-energy I=12 S-wave πN-ηN coupled-channel ... -
Electric-Field-Induced IR Absorption in Diamond
(University of Nairobi, 1976)Electric-field-induced absorption of a type IIa diamond has been measured at various resolutions over a wider spectral range (2300 to 2700 cm-1) than hitherto. A new feature has been observed at 2335 cm-1 close to the ... -
Chapter 23 - Monitoring Drought with the Combined Drought Index in Kenya
(University of Nairobi, 2013)A first step in any drought management system is to monitor the state and the evolution of the drought. This study addresses the problem of nonexistent operational drought monitoring systems and presents a new methodology ... -
Chapter 16 – Freshwater Ecology of Kenyan Highlands and Lowlands
(University of Nairobi, 2013)Freshwater ecosystems of Kenya are the lifeline of economic and social development; however, most of these are threatened or on the verge of collapse. The need to maintain them in their natural condition, reduce disturbance ...
