Characterization of asian and north American avian H5N1
(Scientific Research Publishing, 2011-07)Since the emerge of the highly pathogenic avian H5N1 virus in Asia in 1996, the possibility for this virus to cross species barriers to infect humans and its ability to cause large outbreaks in birds have been a public ... -
Characterization of bacteria isolated from rumen substrates of goat (Capra aegagrus hircus)
(African Journal of Biological Sciences, 2020-04-06)Studies on microorganisms associated with rumen substrates of goat (Capra aegagrus hircus) were done through aerobic and anaerobic fermentation for a period of 12 days. Microscopic, biochemical and molecular identification ... -
Characterization of Carica Papaya Seedlings Pathogens In Kamiu Tree Nurseries at Embu County
(University of Embu, 2021-09)Papaya (Carica papaya L.) is an important fruit crop cultivated in many parts of the world. Its cultivation happens in different stages; from seeds, to seedling and finally to a grown papaya crop. Papaya crop in its ... -
Characterization of cerium doped yttrium gadolinium aluminate garnet (Y-Gd)3Al5O12:Ce3+ phosphor thin films fabricated by pulsed laser deposition
(2015)Thin films of cerium doped yttrium gadolinium aluminate garnet (Y-Gd)3Al5O12:Ce3+ (YGAG:Ce) were grown on Si(100) substrates by a pulsed laser deposition (PLD) technique using a 266 nm Nd:YAG pulsed laser under varying ... -
Characterization of composite material from the copolymerized polyphenolic matrix with treated cassava peels starch
(Heliyon, 2020-07)Conventional binders in the particleboards formulation involve use of formaldehyde resins. Epidemiologic studies show that formaldehyde is carcinogenic. Efforts to reduce formaldehyde emissions by use of scavengers has ... -
Characterization of Kenyan French Bean genotypes into gene pool affiliations using allele specific markers
(ACADEMIC JOURNALS, 2020-07)French bean (Phaseolus vulgaris L.) is a major export crop in Kenya where it serves as a cash crop for smallholder farmers and a source of employment. However, there is limited information on characterization of available ... -
Characterization of Local Nano-Heat Transfer Fluids for Solar Thermal Collection
(Hindawi, 2020-08)Performance of organic oils in solar thermal collection is limited due to their low thermal conductivity when they are compared to molten salt solutions. Extraction of organic oils from plants can be locally achieved. 'e ... -
