Assessment of knowledge of malaria and its control practices in mining and sugarcane growing regions of Western Kenya highlands
(African Health Sciences, 2022-07-29)Background: Despite upscaled control efforts, deaths and hospitalization due to malaria remained high in counties of western Kenya highlands. Objectives: This study assessed the knowledge of malaria in two rural communities, ... -
Distribution, Characterization and the Commercialization of Elite Rhizobia Strains in Africa
(International Journal ofMolecular Science, 2022-06-13)Grain legumes play a significant role in smallholder farming systems in Africa because of their contribution to nutrition and income security and their role in fixing nitrogen. Biological Nitrogen Fixation (BNF) serves a ... -
Effects of lime and fertilizer on soil properties and maize yields in acid soils of Western Kenya
(Academic Journals, 2018-03-29)Many soils in Western Kenya are acidic and deficient in nitrogen and phosphorus. Acidity hinders crop responses to fertilizers applied to remedy nutrient deficiencies. The common liming materials used to ameliorate acidity ... -
Tool for determining levels and classifying; host plant resistance, tolerance to stress, vigour and pathogen virulence in plants
(Scientific African, 2022-07)The global food security and plant resources levels are continuously under threat from climate change, environmental pollution, population pressure, co-evolving plant pests and pathogens. Currently, scientists across the ... -
Integrated Management of Napier Grass Stunt Disease in East Africa
(Sustainability in Plant and Crop Protection, 2020-02-06)Napier grass stunt (NGS) disease is a serious disease of the most important fodder crop in East Africa. The disease is caused by a phytoplasma, ‘Candidatus Phytoplasma oryzae’, a cell wall-less bacterium belonging to the ... -
Insecticide resistant Anopheles gambiae have enhanced longevity but reduced reproductive fitness and a longer first gonotrophic cycle
(scientific reports, 2022-05-23)Widespread insecticide resistance in African malaria vectors raises concerns over the potential to compromise malaria vector control interventions. Understanding the evolution of resistance mechanisms, and whether the ... -
Prehospital Airway Management for Trauma Patients by First Responders in Six Sub-Saharan African Countries and Five Other Low- and Middle-Income Countries
(World Journal of Surgery, 2022-02-25)The global injury burden disproportionately affecting low- and middle-income countries (LMICs) is exacerbated by a lack of robust emergency medical services. Though airway management (AM) is an essential component of ... -
Pragmatic restaurant tipping in star-rated hotels in Kenya
(Tailor and Francis online, 2021-12-10)Tipping can be traced to Tudor England in the sixteenth century. This act transformed into a custom, spreading to many countries. However, tipping is observed differently from one country to the other and thus is not ... -
