Short Communication: Effect Of Lime, Urea And Triple Super Phosphate On Nitrogen And Phosphorus Mineralisation In An Acid Soil During Incubation
(2000)A significant portion of soil N and P occurs in organic forms that are not available for crop uptake unless mineralised ( Stevenson, 1986; Tisdale et al., 1990). Slowed nitrification rates (Weber and Gainey, 1962) and P ... -
Short proline-rich lipopeptide potentiates minocycline and rifampin against multidrug- and extensively drug-resistant pseudomonas aeruginosa.
(University of Nairobi, 2018)A series of 16 short proline-rich lipopeptides (SPRLPs) were constructed to mimic longer naturally existing proline-rich antimicrobial peptides. Antibacterial assessment revealed that lipopeptides containing hexadecanoic ... -

Signal transduction in malaria gametocytes. biochemical pathways in parasites of medical importance
(University of Nairobicollege of biological and physical science, 1998)Cultivated Plasmodium falciparum gametocytes reach maturity in vitro in approximately 14-16 days, during which they pass through five morphologically distinct developmental stages. Purification of the earlier developmental ... -
The Signaling Hypothesis: Evidence From The Nairobi Securities Exchange
(Department of Accounting and Finance, Mount Kenya UniversityDepartment of Industrial Mathematics, University of NairobiDepartment of Accounting and Law, William Paterson University, 2012)This study investigates the signaling hypothesis by testing the displacement property of dividends. The study uses Ohlson (1995; 2001) model and follows Hand and Landsman (2005) approach. The study however varies the ... -
Signatures of selection and drivers for novel mutation on transmission-blocking vaccine candidate Pfs25 gene in western Kenya
(University of Nairobi, 2022-04)Background: Leading transmission-blocking vaccine candidates such as Plasmodium falciparum surface protein 25 (Pfs25 gene) may undergo antigenic alterations which may render them ineffective or allele-specific. This study ... -
The significance of Aswa Lineament in South Sudan; 15th Colloquium on Geology of Africa in Nancy, France
(University of NairobiDepartment of Geology, 1990) -
The significance of groundwater flow for the hydrologic budgets of paleo-lakes in the East African rift
(Department of Geology, University of Nairobi,Universite Joseph Fourier LGIT,, 2011)The hydrogeology of rift lakes is complex due to the potential influence of faults and porous volcanic and volcanoclastic media on groundwater flow. We conducted a comprehensive study that integrated geological and ... -
The significance of variation in the susceptibility of Schistosoma mansoni to the antischistosomal drug oxamniquine.
(University of Nairobi,Department of Zoology, 1987)Clinical and laboratory evidence is reviewed which shows that there is a great deal of variation in the susceptibility of Schistosoma mansoni to oxamniquine. This variation occurs both among endemic regions and within ... -
The silver cyprinid Rastrineobola argentea as the main diet source for rearing Anopheles arabiensis mosquitoes
(University of Nairobi, 2014)Background & objectives: All organisms that are cultured for laboratory bioassays need food for sustenance and amplification of the colony to such numbers that would not compromise the progress of the research at hand. For ... -
Similarity of Operators in a Complex Hilbert Space
(University of Nairobi.School of Mathematics, 2008) -
Similarity of Operators in a Hilbert Space
(2008)One of the earliest non-trivial results about similarity is Nagy's converse: if A is invertible and both A and A -I are power bounded, then A is similar to a unitary operator. If A and B are operators. and if at least one ... -

A simple method for maintaining, detecting and recovering virulent Leishmania donovani in hamsters
(University of NairobiDepartment of Zoology, 1996-02)The ability of hamsters (Mesocricetus auratus) to retain amastigotes of Leishmania donovani at cutaneous sites was examined. Following intradermal inoculation of L. donovani stationary phase culture promastigotes in fore ... -
A Simple Method for Sampling Indoor-Resting Malaria Mosquitoes Anopheles gambiae and Anopheles funestus (Diptera: Culicidae) in Africa
(Entomological Society of AmericaDepartment of Zoology, University of Nairobi, Nairobi, Keny, 2006)Sampling indoor resting African malaria vectors is traditionally done by hand catches with oral or mechanical aspirators and pyrethrum spray catches (PSCs). In this study, we designed and brießy evaluated an inexpensive ... -
A Simple Method for Storing Mosquito Bloodmeals for Human DNA Profiling
(Department of Zoology, University of Nairobi, 2002)A simple method for storing mosquito bloodmeal samples, which permits extraction and detection of human DNA after polymerase chain reaction (PCR) amplification of target DNA sequences, was tested. Abdomens of bloodfed ... -
