Determination of damage threshord of gassava green (acari: tetranychidae) on different cassava varieties
(University of Nairobi, 2014) -
Impact of longterm inorganic fertilization with emphasis on heavy metals, soil PH and total organic carbon on maize farm soils in trans Nzoia Kenya.
(University of Nairobi, 2014)This research was carried out to analyze the effect of long term use of inorganic fertilizers on the Cd, Cr, Cu, Pb, Zn, soil pH and TOC in maize farm soils in Kenya. Samples of soil were collected from 12 experimental ... -
Putnam-Fuglede Theorem For N-Power Normal And W-hyponormal Operators,
(University of Nairobi, 2014)Reducibility implies direct sum decompositions of Hilbert space operators and any pair of operators which satisfy the Putnam-Fuglede theorem is reducible. In this presentation, the familiar Putnam-Fuglede theorem is ... -
SAR arcs and 6300 Å emission by dissociative recombination of O2+ observed from Africa during severe magnetic storms
(University of Nairobi, 2002)SAR arcs were observed from Southern Africa on 17/18 December 1971, 4/5 August 1972 and 1/2 April 1973 with the equatorwards edge at L = 1.8. Simultaneous with the latter event the intertropical arc was observed at an ... -
An experimental study of palaeosecular variation
(University of Nairobi, 1971-05-17)A total of 83 selected palaeomagnetic results are used in a latitude analysis of palaeosecular variation to show that Cox's 1970 model for secular variation fits the data, provided the dipole wobble is between 1 1/2° and ... -
Putnam’s inequality for n-Power normal, n-Power quasinormal and w-hyponormal operators,
(University of Nairobi, 2014)Every reducible operator can be decomposed into normal and completely non-normal operators. Unfortunately, there are several non normal operators which are irreducible. However, every operator whose self-commutator is ... -
Low enthalpy geothermal systems in Kenya
(University of Nairobi, 1988)The location of Kenya's geothermal fields is shown. The chemistry of the low enthalpy fields is given and reservoir temperatures estimated from these data. The most promising of these fields are the Mwananyamala, Homa ... -
Indirect Ppectrometric determination of phosphate
(1994)This paper reports the development of an alternative quantitative analytical procedure for the determination of phosphate by an indirect method. It involves the precipitation of magnesium ammonium phosphate, which is ... -
Seasonal-to-Interannual Climate Variability in the Context of Development and Delivery of Science-based Climate Prediction and Information Services Worldwide for the Benefit of Society
(2010)Examples of seasonal-to-interannual rainfall variability in Africa demonstrate how the society is under serious threat due to increasing natural disasters linked to climate variability and change. Recognition of the different ... -
An elusive search for regional flood frequency estimates in the River Nile basin
(University of Nairobi, 2012)Estimation of peak flow quantiles in ungauged catchments is a challenge often faced by water professionals in many parts of the world. Approaches to address such problem exist, but widely used techniques such as flood ... -
Airborne Spectral Measurements of Ocean Directional Reflectance
(2005)The Cloud Absorption Radiometer (CAR) was flown aboard the University of Washington Convair 580 (CV-580) research aircraft during the Chesapeake Lighthouse and Aircraft Measurements for Satellites (CLAMS) field campaign ... -
Chemical Communication in the Honey Bee Scarab Pest Oplostomus haroldi : Role of ( Z )-9-Pentacosene
(University of Nairobi, 2012)Oplostomus haroldi Witte belongs to a unique genus of afro-tropical scarabs that have associations with honey bee colonies, from which they derive vital nutrients. Although the attributes of the honey bee nest impose ... -

Deletion of Plasmodium falciparum Histidine-Rich Protein 2 (pfhrp2) and Histidine-Rich Protein 3 (pfhrp3) Genes in Colombian Parasites
(2015)A number of studies have analyzed the performance of malaria rapid diagnostic tests (RDTs) in Colombia with discrepancies in performance being attributed to a combination of factors such as parasite levels, interpretation ...
