SARS-CoV-2 Detection in Fecal Samples in Sym-asymptotic Patients with Typical Findings of COVID-19 on Ag-RDT and SARS-CoV-2 RT-PCR Tests
(Preprints, 2022-09-28)Coronavirus is a disease caused by a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which emerged as a global pandemic in 2019 from Wuhan, China. Since its emergence, it has caused immense suffering to human ... -
Seasonal dynamics in carbon dioxide fluxes of the herbaceous layer of a moist Kenyan savannah
(APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2014)Strong seasonal variability in African carbon source/sink relationship is considered the continent’s most significant contribution to the global carbon cycle. Alternating dry and wet periods dictate ecosystem carbon exchange ... -
Seed dispersal by Tana River mangabeys in fragmented gallery forests
(SciRes., 2012)Data collected on a free ranging group of Tana River mangabeys (Cercocebus galeritus) indicates that this endangered primate species, which has previously been regarded as a seed predator, plays an important role in seed ... -
Sensitivity Analyses of Population Projection Matrix of Cestrum Aurantiacum
(Kenya Forestry Research Institute/Jaramogi Oginga Odinga University of science and Technology., 2020)The Lefkovitch stage specific matrix population models are divided into discrete stage classes defined by a growth variable such as size, height and diameter at breast height for trees. In matrix model, the deterministic ... -
Sensitivity of peatland herbaceous vegetation to vapor pressure deficit influences net ecosystem CO2 exchange
(Society of Wetland Scientists, 2012)Mountain peatlands in the temperate regions represent a small proportion of the global peatland resource, but play a unique, although less recognized role in the regional water and biogeochemical cycles. We conducted leaf ... -
Simple Sequence Repeat (SSR) Genetic Linkage Map of D Genome Diploid Cotton Derived from an Interspecific Cross between Gossypium davidsonii and Gossypium klotzschianum
(Multidisciplinary Digital Publishing Institute, 2018-01-11)The challenge in tetraploid cotton cultivars is the narrow genetic base and therefore, the bottleneck is how to obtain interspecific hybrids and introduce the germplasm directly from wild cotton to elite cultivars. ... -
Socio-Cultural Practices on the Use of Beetle Grubs as Food and Feed in Western Kenya
(Scientific Reports, 2023-05-13)We examined the socio-cultural practices on the use of beetle grubs as food and feed in western Kenya by interviewing 211 randomly selected households and conducting seven focus group discussions in Bungoma, Kakamega, ... -
Socio-economic factors influencing the spread of drinking water diseases in rural Africa: case study of Bondo sub-county, Kenya
(IWA Publishing, 2015)Socio-economic and medical information on Bondo sub-county community was studied to help establish the relationship between the water quality challenges, community health and water rights conditions. Health challenges have ... -
Socioeconomic factors influencing dependence of households on non-timber forest products in South Nandi Forest, Kenya
(Journal of Economics and Sustainable Development, 2018)Forests are some of the key natural assets that provide a wide range of goods and services to forest adjacent communities. However, there is inadequate information on the factors that influence community members’ level of ... -
Soil properties along a gradient from hillslopes to the savanna plains in the Lambwe valley, Kenya
(Elsevier, 2015)Changes in land use and management strongly affect the physical and chemical properties of soils and their ecological functions. Especially, regions in East Africa have experienced dramatic land use changes in the past, ... -
Soil water availability and capacity of nitrogen accumulation influence variations of intrinsic water use efficiency in rice
(Elsevier, 2016)Leaf intrinsic water use efficiency (WUEi) coupling maximum assimilation rate (Amax) and transpirable water lost via stomatal conductance (gsc) has been gaining increasing concern in sustainable crop production. Factors ... -
Spatial heterogeneity in stand characteristics alters water use patterns of mountain forests
(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 ... -
Spatial Heterogeneity of Malaria Vectors and Malaria Transmission Risk Estimated Using Odour-Baited Mosquito Traps
(BMC- Malaria Journal, 2014-09-22)Prior to the commencement of a large-scale malaria intervention study on Rusinga Island, western Kenya, intensive baseline surveillance of the mosquito population was performed using odour-baited traps. The survey aimed ... -
Spatial Motion of Multi-Pendula Systems
(International Journal of Science and Research, 7/7/2017)A multiple chain pendula system constrained to move in space has been studied within the framework of a generalized coordinate system by using the Lagrangian formalism. Equations of motions for many body pendula systems ... -
Spatially Variable Risk Factors for Malaria in a Geographically Heterogeneous Landscape, Western Kenya: An Explorative Study
(Malaria Journal, 2016-06-01)Large reductions in malaria transmission and mortality have been achieved over the last decade, and this has mainly been attributed to the scale-up of long-lasting insecticidal bed nets and indoor residual spraying with ... -
Spin Reorientation, Normal and Inverse Magnetocaloric Effects in Heavy Rare-Earth Iron Garnets
(Elsevier, 2020-08-01)Experiments for heavy rare-earth iron garnets Ho3Fe5O12 and Er3Fe5O12 show a compensation effect characterized by a near zero magnetization at 134 K and 80 K, respectively. The magnetic entropy change calculated according ... -
Stand characteristics and water use at two elevations in a sub-tropical evergreen forest in southern China
