Elephant movement and local community attitudes towards the proposed corridor between Thegu forest and Sangare ranch
(School of Biological Sciences, 2012)Rapid human population growth has drastically reduced elephant range by reducing habitats and blocking traditional migration routes over the last several decades. Attempts to reopen migration routes have been met with ... -
The Negative Binomial Parameter K As A Measure Of Dispersion
(University of NairobiSchool of Mathematics University of Nairobi, 2010)The role of the negative binomial parameter k and index of patchiness as measures of dispersion in relation to random removal of individuals are discussed. The aim of this paper is to demonstrate analytically that the ... -
Modelling Dispersion Using Finite Mixture Of PoissoN
(University of NairobiSchool of Mathematics University of Nairobi, 2011)The negative binomial distribution is a versatile distribution in describing dispersion. The negative binomial parameter k is considered as a dispersion parameter. The aim of this paper is to demonstrate that filnite mixture ... -
An Approximation Of Fisher's Information For The Negative Binomial Parameter K
(University of NairobiSchool of Mathematics University of Nairobi, 2011)The negative binomial distribution is a versatile distribution in describing dispersion. The negative binomial parameter k is considered as a measure of dispersion. The aim of this paper is to present an approximation of ... -
Diversity of lepidopteran stem borers in eastern Africa revisited
(LeRu, BP, Ong'amo G, Moyal P, Ngala L, Musyoka B, Abdullah Z, Cugala D, Defabachew B, Hailei TA, Kauma TM, Lada VY, Negassi B, Ravolonandrianina KJ, Sidumo A, Omwega C, Schulthess F, Calatayud P-A, Silvain J-F. 2006. Diversity of lepidopteran stem borers in eastern Africa revisited. Bulletin of Entomological Research. 96:555-563., 2006)Surveys were completed in Eritrea, Ethiopia, Kenya, Madagascar, Mozambique, Tanzania, Uganda and Zanzibar to assess the lepidopteran stem borer species diversity on wild host plants. A total of 24,674 larvae belonging to ... -
Collision Broadening of Rotational Spectrum
(School of Biological Sciences, University of Nairobi, 1972)The problem studied is the rotational absorption spectrum of linear molecules of moment inertia I in a simple nonpolar buffer gas. The focus is on the behavior of the spectrum as the buffer gas pressure and the associated ... -

Multi-type step-wise group screening designs with unequal a-priori probabilities
(JKUAT Press LtdSchool of Mathematics, University of Nairobi,, 2005)In this paper, we discuss multi-type step-wise group screening in which group-factors contain differing number of factors. We describe a procedure for grouping the factors in the absence of concrete prior information, ... -
Microsatellite analyses reveal fine scale genetic structure of Busseola fusca (Fuller) (Lepidoptera: Noctuidae)

Step-wise group screening strategies for isolating defective items
(JKUAT Press Ltd'Department of Mathematics, Catholic University of Eastern Africa,, 2007)Abstract. In this paper, we consider the application of stepwise group screening procedure to blood screening in populations with low human immunodeficiency virus (HIV) prevalence rate. Expressions for the saving rate ... -
Genetic Diversity and Population Structure of Busseola segeta Bowden (Lepidoptera; Noctuidae): A case study of host use diversification in Guineo-Congolian rainforest relic area, Kenya
(School of Biological Sciences, 2012)Abstract: Habitat modification and fragmentation are considered as some of the factors that drive organism distribution and host use diversification. Indigenous African stem borer pests are thought to have diversified their ... -
Occurrence of Simulium (Edwardsellum) damnosum s.l. (Diptera: Simuliidae) in nine river systems in Kenya
(Department of Entomology, University of Nairobi, Kenya, 1986)Six river systems in Kenya were found to harbor Simulium damnosum Theobald s.l. Two CDC light traps, during 12-h overnight collections at the Isiukhu and Nzoia rivers, caught 3 and 116 adult S. damnosum s.l., respectively. ... -
Step-wise screening of defective factors
(Marcel Dekker, Inc.Moi University, Eldoret, KenyaUniversity. of Nairobi, Kenya, 1992)It is generally assumed that the defective factors of a population have the same a-priori probability" of being defective'. However, with some knowledge of the population, we can relax on this assumption and assume the ... -
