Gametocytemia and Attractiveness of Plasmodium falciparum–Infected Kenyan Children to Anopheles gambiae Mosquitoes
(The Journal of Infectious Diseases, 2017-06-13)It has been suggested that Plasmodia manipulate their vertebrate hosts to enhance parasite transmission. Using a dual-choice olfactometer, we investigated the attraction of Anopheles gambiae to 50 Kenyan children (aged ... -
GBS Mapping and Analysis of Genes Conserved between Gossypium tomentosum and Gossypium hirsutum Cotton Cultivars that Respond to Drought Stress at the Seedling Stage of the BC2F2 Generation
(Multidisciplinary Digital Publishing Institute, 2018-05-30)Cotton production is on the decline due to ever-changing environmental conditions. Drought and salinity stress contribute to over 30% of total loss in cotton production, the situation has worsened more due to the narrow ... -
Generalizations on normal self-ad joint operators
(JGRMA, 2017-09)We consider certain properties of operators. A lot of studies have been done on reflexivity, compactness and numerical radius attainability on Hilbert space operators [1-12] and the reference therein. -
Genome wide identification of the trihelix transcription factors and overexpression of Gh_A05G2067(GT-2), a novel gene contributing to increased drought and salt stresses tolerance in cotton
(John Wiley & Sons Ltd, 2019-01)We identified 102, 51 and 51 proteins encoded by the trihelix genes in Gossypium hirsutum, Gossypium arboretum and Gossypium raimondii, respectively. RNA sequence data and real-time quantitative polymerase chain reaction ... -
A global synthesis of the effects of diversified farming systems on arthropod diversity within fields and across agricultural landscapes
(WILEY, 2017)Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management ... -
Granular and Powdered Lime Improves Soil Properties and Maize (Zea mays L.) Performance in Humic Nitisols of Central Highlands in Kenya
(SSRN, 2022-12-19)Soil acidity is a major constraint to crop production on highly weathered tropical soils characterized by high Aluminum (Al) toxicity, low cation exchange capacity, and low phosphorus (P) availability to plants. The objective ... -
High-Density Linkage Map Construction and Mapping of Salt-Tolerant QTLs at Seedling Stage in Upland Cotton Using Genotyping by Sequencing (GBS)
(Multidisciplinary Digital Publishing Institute, 2017-11-05)Over 6% of agricultural land is affected by salinity. It is becoming obligatory to use saline soils, so growing salt-tolerant plants is a priority. To gain an understanding of the genetic basis of upland cotton tolerance ... -
Higher assimilation than respiration sensitivity to drought for a desert ecosystem in Central Asia
(Elsevier, 2017)Responses of ecosystem assimilation and respiration to global climate change vary considerably among terrestrial ecosystems constrained by both biotic and abiotic factors. In this study, net CO2 exchange between ecosystem ... -
Impacts of selective logging on population structure and dynamics of a canopy tree (Oleacapensis) in Kakamega forest
(African journal of Ecology, 2010-08-03)This study assessed the impacts of logging on the population structure and dynamics of Elgon teak (Olea capensis), a canopy dominant in Kakamega forest. The objective was to ascertain and determine the regeneration status ... -
Implementation of Technology and Innovation Support Centers (Tiscs) in Kenya: Challenges and Opportunities
(Elsevier, 2022-02)Technology and Innovation Support Centers (TISCs) were established by the World Intellectual Property Organization (WIPO) in 2009 to support innovations in least developed countries. They facilitate innovators to access ... -
Implication of pollen character coding and their diagnostic value in the determination of taxonomic resemblance among indigofera linn species
(International Journal of Life Sciences Research, 2017)Whereas phenetics emphasizes the use of maximum characters as practicable, decisions on how observations are translated to characters is of importance in systematics in order to partition objects in to nonoverlapping ... -
In vitro antimicrobial activity of methanolic extracts of different Senna didymobotrya (Fresen.) H. S. Irwin & Barneby plant parts
(Editorial Manager® and ProduXion Manager® from Aries Systems Corporation, 2015)Background: Herbal medicines are used widely for primary health care in Kenya among rural populations where modern medicines are not affordable. The flowers, roots, stems and leaves of Senna didymobotrya have both antifungal ... -
Incremental modernization of statistics teaching and curriculum at Maseno University, Kenya
(ISI/IASE], 2010)Modernisation of statistics teaching is a continual problem the world over. The advances in statistical methods and tools along with the growing demand of applied practitioners creates a dual need of people with the ... -
Independent and Interactive Effect of Plant and Mammalian Based Odors on The Response of the Malaria Vector, Anopheles Gambiae.
(Science Direct, 2018-05-02)Several studies have shown that odors of plant and animal origin can be developed into lures for use in surveillance of mosquito vectors of infectious diseases. However, the effect of combining plant- and mammalian-derived ... -
Inherently delayed germination of Elgon Teak (Olea capensis) seeds in Kakamega Forest, Kenya
(Kamla-Raj, 2010)Olea capensis in Kakamega forest does not show any evidence of natural regeneration under the parent trees. This study sought to determine the factors that may be responsible for the lack of natural regeneration under the ... -
