Variation of plant p,p′-DDT uptake with age and soil type and dependence of dissipation on temperature

Kiflom, Welderufael G; Wandiga, Shem O; Ng'ang'a, Peter K; Kamau, Geoffrey N (Department of Chemistry, University of Nairobi, Nairobi, Kenya, 1999)

The extent to which DDT may be absorbed and translocated from 14C-p,p′-DDT contaminated soils into cowpeas plant tissues, and the variation of uptake of p,p′-DDT by the plants in relation to the dissipation of p,p′-DDT in ...

Variations in the Position and Length of the Vermiform Appendix in a Black Kenyan Population

Mwachaka, Philip; El-busaidy, Hemed; Sinkeet, Simeon; Ogeng'o, Julius A (Hindawi Publishing Corporation, 2014)

Background. Topography of the appendix influences its mobility, degree of mobilization of the cecum, and need for additional muscle splitting during appendectomy. Although appendectomy is a common surgical procedure, there ...

Varietal differences in physiological and biochemical responses to salinity stress in six finger millet plants

Mukami, Asunta; Ng'etich, Alex; Syombua, Easter; Oduor, Richard; Mbinda, Wilton (University of Nairobi, 2020)

Finger millet is an important cereal that is grown in semi-arid and arid regions of East-Africa. Salinity stress is a major environmental impediment for the crop growth and production. This study aimed to understand the ...

Vector Bundles of Low Rank on a multipurpose Space

Maingi, Dmian M. (University of Nairobi, 2013)

ABSTRACT. In this paper we construct vector bundles over a multiprojective space and study their properties. We first set out to establish the existence of monads on a multiprojective space pn X pm, for all integers n,m ...

Vector competence of 7 rhipicephalid tick stocks in transmitting 2 Theileria parva parasite stocks from Kenya and Zimbabwe

Ochanda, H; Young, A. S; Medley, G. F; Perry, B. D (1998)

The competence of 7 different stocks of Rhipicephalus appendiculatus and R. zambeziensis to transmit 2 different stocks of Theileria parva was compared by feeding nymphae of each tick stock simultaneously on infected cattle ...

Vegetation changes over palaeo-time scales in Africa

Olago, D O (University of Nairobi, 2001)

The record of palaeovegetation dynamics in Africa generally extends back to 30000 yr BP, and longer records, where they do exist, tend to be characterised by hiatuses, giving a broken slide-show of vegetation dynamics in ...

Vegetation dynamics of coastal sand dunes near Malindi, Kenya

Musila, W M; Kinyamario, J I; Jungerius, P D (University of NairobiDepartment of Botany, 2001-06)

This study describes the composition, structure and distribution of coastal dune vegetation near Malindi, Kenya. The vegetation was made up of 156 plant species. Sixty families were recorded with Gramineae (seventeen ...
