The effects of salinity on some physiological,Anatomical and biochemical aspects of cowpea (vigna unguiculata (l) walp (legurninosae)
(Department of botany Faculty of science University of Nairobi, 1985)Very little work has been done on the physiology cowpea (Vigna unguiculata) and almost nothing so far, on its response to salinity effects. Cowpea being a drought resistant crop is suspected it might also to some extent ... -
The analytic continuations of distributions
(School of Mathematics, University of Nairobi, 2009)n this dissertation, we develop the elements necessary at providing the theoretical formulation of the solution to the Gel’fand(1954) problem. All the results are well-known and our contribution is only at the level of the ... -
