Mycoflora and mycotoxins in finished fish feed and feed ingredients from smallholder farms in East Africa
(University of Nairobi, 2017)A total of 52 samples of finished fish feeds and ingredients were collected from smallholder farmers in Kenya, Tanzania, Rwanda and Uganda, and analyzed. Culture and molecular techniques were used to identify fungal ... -
Mycotoxin problem in Africa: Current status, implications to food safety and health and possible management strategies
(2008)Mycotoxins are toxic secondary metabolites of fungal origin and contaminate agricultural commodities before or under post-harvest conditions. They are mainly produced by fungi in the Aspergillus, Penicillium and Fusarium ... -
Myoglobin coadsorbed on electrodes from microemulsions provides reversible electrochemical catalysis. Langmuir, 2003, 19, 6976
(Department of Chemistry, 2003)The iron heme protein myoglobin (Mb) coadsorbs with surfactant onto glassy carbon, pyrolytic graphite, and platinum electrodes from microemulsions of sodium dodecyl sulfate or cetyltrimethylammonium bromide, water, oil, ... -
Myoglobin retains iron heme and near-native conformation in DDAB films prepared from pH 5 to 7 dispersions. Electrochem Commun. 2006, 8, 455
(Department of Chemistry, 2006)A recent paper [M.T. DeGroot, M. Merkx, M.J.M. Koper, J. Am. Chem. Soc. 127 (2005) 16224] suggests that iron heme is released during casting films of myoglobin (Mb) and didodecyldimethylammonium bromide (DDAB) on pyrolytic ... -
Myristoyl Esters of Lactose", Carbohydrate Research, 125, 253-263.
(J. Sci. TechnolDepartment of Chemistry, 1984-02)Whereas lactose did not undergo a base-catalyzed transesterification with methyl esters of fatty acids, methyl beta-lactoside reacted under identical conditions to give mono- and di-myristates. This difference in behavior ... -
The Mystery of Trichothecene Antibiotics in Baccharis Species
(Department of Chemistry, 1988-08)The Brazilian higher plant Baccharis coridifolia has been shown to synthesize de novo a series of highly toxic macrocyclic trichothecene antibiotics heretofore found to be produced only by fungi. These compounds are produced ... -
Nairobi National Park Game Census, 1966
(University of Nairobi, 1967)1. The monthly game counts of Nairobi National Park in 1966 are compared with those of 1961 to 1983 inclusive. It appears that the mean an-nual population of wild ungulates has remained constant at about 4000 animais after ... -
The Nairobi river basin programme; assessment of the Nairobi rivers
(Department of zoology, University of NairobiDepartment of Chemistry, University of Nairobi, 2009)Nairobi Rivers have deteriorated over time due to rapid population growth, urbanization, industrialization coupled with poor urban planning. The water is currently considered unfit for human use thaugh it continues to ... -

Naphthalene Derivatives from the Roots of Pentas parvifolia and Pentas bussei
(University of Nairobi, 2016)The phytochemical investigation of the CH2Cl2/MeOH (1:1) extract of the roots of Pentas parvifolia led to the isolation of three new naphthalenes, parvinaphthols A (1), B (2), and C (3), two known anthraquinones, and five ... -
Naphthoquinones from the roots of Aloe secundiflora
(Department of Chemistry, 2012)Two new naphthoquinones, 5-hydroxy-3,6-dimethoxy-2-methylnaphthalene-1,4-dione and 5,8-dihydroxy-3-methoxy-2-methylnaphthalene-1,4-dione, were isolated from the roots of Aloe secundiflora together with the known compounds ... -

Natural and experimental studies on domestic animal infections with visceral and cutaneous leishmaniases in Kenya.
(10/3/2012)The control of visceral and cutaneous leishmaniases in Kenya has been difficult due to poor knowledge of animal reservoirs of these diseases. Little is known about the feeding preferences of phlebotomine sand flies that ... -
Natural Convection with Localized Heating and Cooling on Opposite Vertical Walls in an Enclosure
(2013)This is a numerical study of turbulent natural convection flow in a rectangular enclosure. The flow of heat is one form of Newtonian motion. We consider natural convection in a three dimensional rectangular enclosure in ... -
