The Distribution Of Organochlorine Pesticide Residues In The Marine Environment Along The Coastal Region Of Kenya
(University Of Nairobicollege of biological and physical science, 1999)Samples of seaweed, water, sediment and nine species of fish were collected from Kenya's coastal sites at Kilifi, Malindi, Sabaki River, Tana River and Lamu Bay between May 1998 and January 1999. The samples were examined ... -
Distribution of spectra in a direct sum decomposition of some classes of operators
(School of Mathematics, University of Nairobi, 2009)The existence of direct sum decompositions and factorizations of bounded linear operators acting on a Hilbert space appears to be one of the most difficult questions in the theory of linear operators. The direct sum ... -
The Distribution Of Two Major Plant Groups (bryophytes And Tracheophytes) Along An Altitudinal Gradient On Naro Moru Track, Mount Kenya.
(University of Nairobi, 2015)Tropical mountain forests are known as the cradle of flowering plants and have many archaic angiosperm taxa. However processes of climate change and human activities have resulted in massive degradation and loss of ... -
