The task of University Botanic Garden in education and plant conservation
(Botanic Gardens Conservation International, 2007)Biological conservation is a complex undertaking especially in the developing countries where large populace still relies on the forest products for their daily survival. Majority of these people live below the poverty ... -
Taxonomic Identification and Characterization of African Nightshades (Solanum L. Section Solanum)
(African Journal of Food, Agriculture, nutrition and developmen, 2007)African nightshades play an important role in meeting the nutritional needs of rural households, and are reported as being particularly rich in protein, vitamin A, iron and calcium. Nightshades are among three top priority ... -
Taxonomic Studies of Lippia javanica (Burm F.) Spreng. Complex (Verbenaceae) in East African Flora
(Asian Journal of Research in Botany, 2021)Lippia javanica complex is widely spread in Eastern, Central and Southern Africa; however, there exist a taxonomic conflict in the aforementioned species complex where morphologically similar forms of the species occur in ... -
Tea
(Oxford, 2003)This article focuses on the process of tea fermentation. Tea beverages are processed from the young tender shoots of Camellia sinensis L. O. Kuntze. Because of its subtle flavors and health benefits, tea has become the ... -
Tea (Camellia sinensis (L). O Kuntze) Variations in Yields, Yield Components and Leaf Nutrients Responses to Geographical Location and Nitrogen Fertiliser Rates in Kenya
(Maseno University, 2017)Tea provides income and employment to rural populations in many countries. Tea, grown in east and west of the Rift Valley, is the leading export commodity crop in Kenya. Variable responses among genotypes to different ... -
Tea Aroma
(Chapman and Hall, London, 1992)Tea is manufactured by a variety of processes producing a range of beverages from green, non-fermented tea through to black, fermented tea. The consumer acceptability of these beverages is largely dependent on the flavor ... -
Technology Options for the Built Environment in Kenya: Dye- Sensitized and Amorphous Silicon Photovoltaics for Application in NZE Buildings
(Bentham Science Publishers Ltd., 2017)Background The performance of a Dye-Sensitized Solar Module (DSSM) has been investigated under different outdoor air mass (AM), irradiance intensity and temperature conditions in Wajir, Kitui, Vihiga and Kajiado Counties ... -
Temperature-Dependent Elastic Constants of Substrates for Manufacture of Mems Devices
(Kabarak university, 2022)We present a comparative computational study of temperature-dependent elastic constants of silicon (Si), silicon carbide (SiC) and diamond as substrates that are commonly used in the manufacture of Micro-Electromechanical ... -
Tenax extraction for exploring rate-limiting factors in methyl-β-cyclodextrin enhanced anaerobic biodegradation of PAHs under denitrifying conditions in a red paddy...
(Elsevier, 2014-01-15)The effectiveness of anaerobic bioremediation systems for PAH-contaminated soil may be constrained by low contaminants bioaccessibility due to limited aqueous solubility and lack of suitable electron acceptors. Information ... -
A test for relative efficiency in the Smallholder Tea Sub-sector in Kenya
(Department of Agricultural Economics; University of Nairobi., 2001)Despite availability of tea growing technologies to all Kenya tea farmers, green leaf production in smallholder sub-sector remains low. Tea in Kenya is grown in the East of the Rift Valley and the West of the Rift Valley ... -
The Test of Entanglement of Polarization States of a Semi-Classical Optical Parametric Oscillator
(Science Publishing Group, 2017)We study the dynamical continuous variable entanglement in a semi-classical Optical parametric oscillator (OPO). The general time evolving photon polarization state vectors arising from exact analytical solutions of ... -
Testosterone positively associated with both male mating effort and paternal behavior in savanna baboons (Papio cynocephalus)
(Academic Press, 2013-03-31)Testosterone (T) is often positively associated with male sexual behavior and negatively associated with paternal care. These associations have primarily been demonstrated in species where investment in paternal care begins ... -
Tetracycline efflux pump in different Salmonella enterica isolated from diarrhea patients in two rural health centers in Western Kenya
(Infectious Diseases and Tropical Medicine Research Center, 2011)Tetracyclines (TCs) are a type of broad-spectrum bacteriostatic antibiotics used for treatment of a wide variety of infections. These antibiotics eventually reach terrestrial and aquatic environments via application of ... -
Theoretical realization of a two qubit quantum controlled-not logic gate and a single qubit Hadamard logic gate in the anti-Jaynes-Cummings model
(Cornell University, 2021)We provide a theoretical scheme for realizing a Hadamard and a quantum controlled-NOT logic gates operations in the anti-Jaynes-Cummings interaction process. Standard Hadamard operation for a specified initial atomic state ... -
