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 ... -
