Bacterial Diversity in the Haloalkaline Lake Elmenteita
(Springer-Verlag, 2010-06)Lake Elmenteita is one of the alkaline saline lakes within the Kenyan Rift valley. The lake is situated on the floor of the Kenyan Rift Valley at 1,776 m above sea level and has no direct outlet. The microbial diversity ... -
Bandwidth selection in smoothing functions
(2006)A simple criterion for selecting a bandwidth parameter that controls the amount of smoothing in functions is described. The procedure is computationally inexpensive and, hence, worth adopting. We argue that the bandwidth ... -
Barriers to Immediate Post-Partum Intra-Uterine Contraceptive Device Uptake among Mothers Delivering at Meru Hospital
(Scientific Research Publishing, 2019-03)Global contraceptive use is at 64%, Africa lagging behind at 33.4%. Kenya has an unmet need for family planning at 23%. Hormonal injections are the most used in Africa at 9.8% and Intra-Uterine Contraceptive Devices at ... -
Basic Capabilities Effect: Collective Management of Pastoral Resources in South Western Kenya.
(Elsevier, 2016-03)Collective action, such as common resource user groups, has gained importance in the management of pastoral natural resources. This study aims at analyzing the effects of basic capabilities, among other factors, on households' ... -
Behaviour Disorders Related to Drug Abuse Among Secondary School Students in Kenya.
(IISTE, 2015)The purpose of this study was to find out the behavior disorders displayed by secondary school students as a result of substance abuse. This would assist to train teachers on specialized intervention methods so that they ... -
Behavioural Patterns and Responses to Human Disturbances of Wild Somali Ostriches (Struthio molybdophanes) in Samburu, Kenya.
(2016-08)Somali ostrich has suffered a drastic decline in its population and range mainly due to hunting over the years for meat, skin and feathers. Urgent conservation measures should therefore be taken to reverse this trend ... -
Beneficiation of Iron in Thermal-Reduced Ilmenite by Magnetic Separation
(2013)ncreasing demands for Iron in countries development, and lack of conventional reducing agents has resulted into sourcing of alternative ways of beneficiating the iron ore. This paper reports on the study that was done ... -
Bibliometrics, Scientometrics, Webometrics / Cybermetrics, Informetrics and Altmetrics - An Emerging Field in Library and Information Science Research
(Shanlax International Journal of Education, 2018)This Article discusses the features and the use of Metrics such as Bibliometrics, Scientometrics, Webometrics, Informetrics and Altmetrics in the field of Library and Information Science Research at present -
Bioactive steroidal alkaloid glycosides from Selanum aculeastrum.
(2002)Solanum aculeastrum Dunal was investigated for the presence of molluscicidal compounds. This led to the isolation of solaculine A, from the root bark in addition to known steroidal alkaloids; solamargine and beta-solamarine ... -
Biocementation Influence on Flexural Strength and Chloride Ingress by Lysinibacillus sphaericus and Bacillus megaterium in Mortar Structures
(Hindawi, 2020-05)The concrete/mortar durability performance depends mainly on the environmental conditions, the microstructures, and its chemistry. Cement structures are subject to deterioration by the ingress of aggressive media. This ... -
Biochemical Composition Within Coffea arabica cv. Ruiru 11 and Its Relationship With Cup Quality
(Canadian Center of Science and Education, 2014-01-14)Biochemical composition appears to be influenced by both genetic factors and plant growth conditions. The main objective of this study was to evaluate the biochemical composition of selected Ruiru 11 sibs and its relationship ... -
Biomass and productivity of seagrasses in Africa
(De Gruyter, 2016-05): There is growing interest in carbon stocks and flows in seagrass ecosystems, but recent global reviews suggest a paucity of studies from Africa. This paper reviews work on seagrass productivity, biomass and sediment ... -
Bioremediation of mortar made from Ordinary Portland Cement degraded by Thiobacillus thioparus using Bacillus flexus
(Heliyon, 2021-06)Cement is widely used as a construction material in the construction industry. However, there are challenges affecting its durability efficacy. Cement mortar/concrete is subject to degradation by aggressive ions such ... -
Biosafety education relevant to genetically engineered crops for academic and non-academic stakeholders in East Africa
(2009-01-15)Development and deployment of genetically engineered crops requires effective environmental and food safety assessment capacity. In-country expertise is needed to make locally appropriate decisions. In April 2007, biosafety ... -
The 'Cake on the plate' syndrome ... and how specialist tansy aphids avoid extinction by hungry predators and parasitoids: insights from the use of polymorphic microsatellite markers
(2008)It was initially shown from 12.2 m high suction trap aerial density data and later confirmed using polymorphic molecular markers (initially allozymes, later high resolution DNA markers, especially microsatellites), that ... -

Carbon in the Coastal Seascape: How Interactions Between Mangrove Forests, Seagrass Meadows and Tidal Marshes Influence Carbon Storage
(Springer, 2018-04)Purpose of Review We use the ‘seascape’ concept to explore how interactions between mangrove forests, tidal marshes and seagrass influence the storage of carbon in these ecosystems. Mangrove forests, with the other two ... -
Carbon storage in the seagrass meadows of Gazi Bay, Kenya
(2017-05-10)Vegetated marine habitats are globally important carbon sinks, making a significant contribution towards mitigating climate change, and they provide a wide range of other ecosystem services. However, large gaps in knowledge ...
