START/PAGES Activities in Sub-Saharan Africa
(University of Nairobi., 2001-08)
Africa is a rich repository of palaeoenvironmental and palaeoclimatic change. It is unique in that it is the only continent that, almost symmetrically, straddles the equator, and hence experiences both northern and southern ...
Fuzzy Ideals and Weak Ideals in BCK-Algebras
(2001)
In this paper, we use the notion of fuzzy point to study some basic algebraic
structures such as BCK-algebras and ideals. Then we clarify the links between the fuzzy
point approach and the classical fuzzy approach.
Vegetation changes over palaeo-time scales in Africa
(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 ...
Growth features of Acacia tortilis and Acacia xanthophloea seedlings and their response to cyclic soil drought stress
(University of Nairobi,, 2001)
Seedlings of Acacia tortilis (Forsk) Hyne and Acacia xanthophloea Benth. were raised under controlled glasshouse conditions. Control plants were watered daily while other treatments involved withholding water for 2, 4 and ...
Mechanistic model simulations of the East African climate using NCAR regional climate model: influence of large-scale orography on the Turkana low-level jet
(University of Nairobi, 2001-06)
The National Center for Atmospheric Research regional climate model (RegCM) is employed to study the
dynamics of the Turkana low-level jet that lies between the Ethiopian and the East African highlands, and ...
Response of Amblyseius cydnodactylon ( Phytoseiidae) to increasing prey density of Tetranychus urticae ( Tetranychidae) in absence or presence of nymphs of Bemisia tabaci ( Homoptera) in Egypt.
(University of Nairobi, 2001)
The predacious mite, Amblyseius cydnodactylon Shehata & Zaher (Phytoseiidae) is a common natural enemy inhabiting low growing plants like cucumber in Egypt. It has been recorded associated with infestations of the two-spotted ...
ASCUS in screening
(2001)
The significance and use of the cytological diagnosis "atypical squamous cells of undetermined significance" (ASCUS) remain a major problem in cervical cancer screening. The prevalence of ASCUS by patient age has seldom ...
Management issues in Lake Victoria watershed
(2001)
Lake Victoria is the largest lake in Africa (68 800 km2) and is the eighth largest lake in the world by volume. The three East African countries of Tanzania, Uganda and Kenya share Lake Victoria and its resources. The total ...
