Restoring soil nutrient stocks using local inputs, tillage and sorghum-green gram intercropping strategies for drylands in Eastern Kenya
(UoEm, 2023)Soil macronutrient and micronutrient availability is particularly critical in semi-arid agro- ecological zones that are characterized by poor soil fertility and low rainfall regimes. An experiment was initiated in S ... -
Review of Carbonation Resistance in Hydrated Cement Based Materials
(Hindawi, 2019)Blended cements are preferred to Ordinary Portland Cement (OPC) in construction industry due to costs and technological and environmental benefits associated with them. Prevalence of significant quantities of carbon dioxide ... -

A Review on Pyroprocessing Techniques for Selected Wastes Used for Blended Cement Production Applications
(Hindawi, 2020-08)Pyroprocessing is an important stage in cement manufacturing. In this process, materials are subjected to high temperatures so as to cause a chemical or physical change. Its control improves efficiency in energy utilization ... -
The rise of potentially toxin producing cyanobacteria in Lake Naivasha, Great African Rift Valley, Kenya
(Elsevier, 2013-07)Lake Naivasha, an important inland water ecosystem and a crucial freshwater resource in the Great African Rift Valley, has displayed clear signals of degradation in recent decades. We studied the phytoplankton composition ... -
Risk Assessment and Fraud Prevention in Banking Sector
(2020)The objective of the study was to assess the effect of risk assessment on fraud prevention in banking industry in Kenya. The study involved all banks in Kenya. Descriptive and correlational research designs were used in ... -
The Role of Indigenous Knowledge Systems in Enhancing Agricultural Productivity in Kenya
(2019)This paper gives an insight into the role of indigenous knowledge systems in improving agricultural productivity in Kenya. It examines how application of indigenous knowledge can help to scale up sustainable agricultural ... -
Roles of doping ions in afterglow properties of blue CaAl2O4:Eu2+,Nd3+ phosphors
(2014-04)Eu2+ doped and Nd3+ co-doped calcium aluminate (CaAl2O4:Eu2+,Nd3+) phosphor was prepared by a urea-nitrate solution combustion method at furnace temperatures as low as 500 °C. The produced CaAl2O4:Eu2+,Nd3+ powder was ... -
Root and soil health management approaches for control of plant-parasitic nematodes in sub-Saharan Africa
(Elsevier, 2021-10)Smallholder farmers in sub-Saharan Africa (SSA) face several challenges that include pests and diseases. Plant-parasitic nematodes (PPN) reduce crop yields and affect their quality. They are an emerging threat to smallholder ... -
Rosemary (Rosmarinus officinalis L.) growth rate, oil yield and oil quality under differing soil amendments
(Heliyon, 2022)In this work, we examined the influence of different soil amendments namely cow manure alone (Cm), cow manure plus fertilizer (Cm þ F), fertilizer alone (F) and unamended check, control on rosemary growth rate, fat content, ... -
Rules-of-thumb to design a uniform spherical array for direction finding—Its Cramér– Rao bounds' nonlinear dependence on the number of sensors
(Acoustical Society of America, 2019-02)ABSTRACT This paper discovers rules-of-thumb on how the estimation precision for an incident source's azimuth-polar direction-of-arrival (ϕ,θ) depends on the number (L) of identical isotropic sensors spaced uniformly on ... -
Sahiwal cattle in semi-arid Kenya: genetic aspects of growth and survival traits and their relationship to milk production and fertility
(2011-12)The aim of this study was to estimate genetic and phenotypic parameters for growth and survival traits of Sahiwal cattle in Kenya and determine their relationship to milk production and fertility. Performance records of ... -
SARS-CoV-2 Molecular Clock and Zoonosis
(Academic Journals, 2020-06)SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), associated with Corona Virus Disease 2019 (COVID-19) coined by World Health Organization, belongs to single stranded RNA viruses (ssRNA Viruses) under ... -
Screening for Water Deficit Tolerance, Relative Growth Analysis and Agrobacterium-Infectivity in Tropical Maize [Zea Mays L.] Inbred Lines in Nairobi, Kenya
(2014-12)The gap between maize demand and regional supply is increasing as small-holder farmers grapple with many challenges, key among them drought. Research in identifying maize lines that are tolerant to water deficit and that ... -

Seagrass Loss and Sub-Surface Carbon Fate: Insights from a Long-Term Experimental Removal in Gazi Bay, Kenya
(Jupiter Publishers, 2021-08)Seagrass meadows are considered as global hotspots of blue carbon stocks. However, they suffer global cover loss mainly due to anthropogenic activities. Few is known on the impact of seagrass loss on their blue carbon ... -
Seagrass Removal Leads to Rapid Changes in Fauna and Loss of Carbon
(Frontiers, 2019-03)Seagrass habitats are important natural carbon sinks, with an average of ∼14 kg C m−2 buried in their sediments. The fate of this carbon following seagrass removal or damage has major environmental implications but is ... -
Segmentation and Alignment of Multi-oriented and Curved Text Lines from Document Images
(2015-06)In this paper, we present a novel approach to segment and align multi-oriented and curved text-lines from document images. We assumed that the input document image contains text-lines with arbitrary orientation and ... -
Segregation disortion of anthocyanin morphological marker in F2 population of cross between basmati and environment genic male sterile rice lines
(2013)Basmati rice (Oryza sativa L.) is preferred by many Kenyans yet its yield per hectare is low. This challenge led to initiation of Basmati hybrid rice project in Kenya with a goal of leaping yield benefits of heterosis. ...
