Heavy Metals and Pesticides in Marine Sediment, Seawater, and Seaplants Along the Kenya-Mombasa Coastline
(2003)Marine sediment, seawater and several species of seaplants along the Kenya-Mombasa coastal region were analyzed to determine the levels of heavy metals by AAS and EDXRF and organochlorine pesticides (OCPs) by GLC-ECD. In ... -
Plant growth promotion induced by phosphate solubilizing endophytic pseudomonas isolates
(University of Nairobi, 2015)The use of plant growth promoting bacterial inoculants as live microbial biofertilisers provides a promising alternative to chemical fertilisers and pesticides. Inorganic phosphate solubilisation is one of the major ... -
Distribution of Elastic Fibres in the Human Abdominal Linea Alba
(University of Nairobi, 2015)The linea alba (LA) supports biomechanical stress generated by intra-abdominal pressure. It is believed to contain connective tissue fibres, which provide tensile strength and pliancy. Previous studies have dwelt on collagen ... -
Avian Area Vasculosa and CAM as Rapid In Vivo Pro-angiogenic and Antiangiogenic Models
(University of Nairobi, 2015)Angiogenesis, the development of new blood vessels from preexisting ones, is driven by coordinated signaling pathways governed by specific molecules, hemodynamic forces, and endothelial and periendothelial cells. The ... -
Leaf stomata conductance, leaf water potential and soil water status in panicum maximum (JACQ.) in disturbed and non-disturbed microsites in a semi-arid ecosystem in Kenya
(Jomo Kenyatta University of Agriculture and Technology, 2011)Tropical semi-arid ecosystems are intricate ecosystems characterized by alternating dry-wet cycles. The question of how trees and grasses coexist under a considerable range of environmental and management conditions has ... -
An Investigation on the Effectiveness of Design Ideation Using TRIZ
(2006)Design ideation continues to be one of the mysterious and yet a very important part of the design process. In the past, there have been studies related to how people generate ideas, why some are more productive in idea ... -
The Five-Factor Model personality assessment for improved student design team performance
(2006)Researchers have long noted the correlation of various personality traits and team performance. Studies relating aggregate team personality traits to team performance are scattered in the literature and may not always be ... -
Towards the Definition of a Framework and Grammar for Game Analysis and Design
(University of Nairobi, 2014)The present paper defines an original approach to game analysis and design able to characterize a given game in a simple, yet efficient, way. Inspired by models widely used across the gaming industry, the proposed ... -
The effects of paraffin oil on phototropic and geotropic responses in avena coleoptiles
(University of Nairobi, 1966)Experiments are described which were designed to test the significance of the coleoptile tip as the site of reception of light stimulus leading to negative photo-tropic response under paraffin oil. The results show clearly ... -
Coupled Climate–Economy–Biosphere (CoCEB) model–Part 1: Abatement share and investment in low-carbon technologies
(University of Nairobi, 2015)Abstract. The Coupled Climate–Economy–Biosphere (CoCEB) model described herein takes an integrated assessment approach to simulating global change. By using an endogenous economic growth module with physical and human ... -
Evaluation of Geophagia as a Pathway for Internal Exposure to Ionizing Radiation
(University of Nairobi, 2015)Geophagia, the deliberate ingestion of soil, is a complex eating habit found among animals and human beings around the world. Among other reasons soil ingestion is perceived as a source of essential mineral supplements, ... -
The Hominin Sites and Paleolakes Drilling Project (HSPDP): Understanding the paleoenvironmental and paleoclimatic context of human origins through continental
(2015)The influence of climate and environmental history on human evolution is an existential question that continues to be hotly debated, in part because of the paucity of high resolution records collected in close proximity ... -
