Optical, microphysical and radiative properties of aerosols over a tropical rural site in Kenya, East Africa: Source identification, modification and aerosol type discrimination
(Pergamon, 2018)A better understanding of aerosol optical, microphysical and radiative properties is a crucial challenge for climate change studies. In the present study, column-integrated aerosol optical and radiative properties observed ... -
Spatiotemporal characteristics of aerosols and their trends over mainland China with the recent Collection 6 MODIS and OMI satellite datasets
(Springer Berlin Heidelberg, 2018-03)With the rapid development of China’s economy and high rate of industrialization, environmental pollution has become a major challenge for the country. The present study is aimed at analyzing spatiotemporal heterogeneities ... -
Haemorrhage of gross domestic product from disability-adjusted-life-years among 15-59 year olds in Kenya
(International Medical Society, 2018)This article estimates non-health gross domestic pro-duct (GDP) losses associated with Disability-Adjusted Life Years (DALY) lost among 15-59 year olds (most productive age bracket) in Kenya in 2015. This study ... -
Spatial variations and trends in AOD climatology over East Africa during 2002–2016: a comparative study using three satellite data sets
(Wiley-Blackwell, 2018)Aerosol optical depth (AOD) has become one of the most crucial parameters for climate change assessment. This study presents long-term (2002–2016) spatio-temporal distributions and trends in AOD over East Africa (EA) ... -
Molecular characterization of Echinococcus species in dogs from four regions of Kenya
(Elsevier, 2018-05)Cystic echinococcosis is endemic both in livestock and humans in many parts of Kenya. However, very little data exists on Echinococcus infections in dogs, and therefore their role in maintaining the transmission cycles and ... -
Prevalence and genotyping of Echinococcus granulosus in sheep in Narok County, Kenya
(Springer Berlin Heidelberg, 2018-07)Cystic echinococcosis (CE) is a zoonotic disease caused by the larval stage of Echinococcus granulosus species (sensu lato, s.l.). In East Africa, several species/strains occur in livestock, wildlife, and humans, but there ... -
A 13-year climatological study on the variations of aerosol and cloud properties over Kazakhstan from remotely sensed satellite observations
(Pergamon, 2018-11)The Republic of Kazakhstan, by geographical and climatological conditions, is a key location for the characterization of atmospheric aerosols due to an unprecedented increase of aerosol's concentrations in the recent years. ... -
Differential effects of various African nightshade species on the fecundity and movement of Tetranychus evansi (Acari: Tetranychidae)
(Cambridge Journals, 2011)The tomato red spider mite Tetranychus evansi Baker & Pritchard is a serious pest of solanaceous plants worldwide. Management of this oligophagous pest in African nightshades has been a challenge to smallholder African ... -
Effect of protein: starch ratio on microwave expansion of imitation cheese-based product
(Elsevier, 2011)Microwave expansion of imitation cheese is a novel way of producing a potentially health crispy snack food. This study aimed to investigate the effects of protein:starch (P:S) ratios of 37:0, 24:13, 20:17 or 16:21 and ... -
Echinococcosis in sub-Saharan Africa: emerging complexity
(Elsevier, 2011)Cystic echinococcosis occurs in most regions of sub-Saharan Africa, but the frequency of this zoonosis differs considerably among and within countries. Especially human cases seem to be focally distributed. A number of ... -
Differential effects of various African nightshade species on the fecundity and movement of Tetranychus evansi (Acari: Tetranychidae)
(Cambridge University Press, 2011)The tomato red spider mite Tetranychus evansi Baker & Pritchard is a serious pest of solanaceous plants worldwide. Management of this oligophagous pest in African nightshades has been a challenge to smallholder ... -
Impact of drought on the spatial pattern of transmission of Schistosoma haematobium in coastal Kenya
(The American Society of Tropical Medicine and Hygiene, 2011)We analyzed temporal changes in spatial patterns of active Schistosoma haematobium infection in different age groups and associated them with ponds infested with Bulinus snails. A major drought between 2001 and 2009 ... -
Cost-effective nutrient sources for tissue culture of cassava (Manihot esculenta Crantz)
(Academic Journals (Kenya), 2012)Application of tissue culture technology is constrained by high costs making seedlings unaffordable. The objective of this study was to evaluate the possibility of using locally available fertilizers ... -
Selection, yield evaluation, drought tolerance indices of orange-flesh sweet potato (Ipomoea batatas Lam) hybrid clone.
(Journal of Nutrition and Food Science, 2012)Orange-Fleshed Sweet Potato (OFSP) varieties have high pro-vitamin A and medium amounts of iron and zinc. Drought susceptibility is perceived as one of the major drawbacks of this crop type and currently available varieties ... -
The use of power ultrasound for the accelerated curing of pork
(58 th International Congress of Meat Science and Technology, 2012)Meat curing is a time consuming and labor intensive process. Power ultrasound (US) induces cell disruption and increases mass transfer. This study aims to assess whether US can accelerate the transfer of ... -
Crispiness of a microwave-expanded imitation cheese: Mechanical, acoustic and sensory evaluation
(Elsevier, 2012)The objective of this study was to determine the crispiness of microwave-expanded imitation cheese and compare the results with sensory evaluation. Three cheeses were manufactured with 36%, 19%, or 15% protein; all three ... -
