Grasshoppers play strategic roles in the ecosystems of recycling of plant nutrients and acting a first order consumers along the trophic food webs. Therefore, their distribution and diversity within an ecosystem signify richness and evenness.  Despite their usefulness, very little is known about the diversity, the relative abundance as well as the distribution of Caeliferans in Africa and more so, Kenya.

Bacterial wilt caused by Ralstonia solanacearum is one of the two major potato diseases in Rwanda. An in vitro study was conducted to identify and differentiate the pathogen isolated from three potato cultivars highly susceptible to R. solanacearum in Rwanda namely Kinigi, Kirundo and Gikungu.

A laboratory study was conducted to determine chemical composition of Azadiractin indica   and Ricinus communis seed oils grown in Marigat, Baringo County, Kenya . Seed oils of A. indica and R. communis were   extracted from mature dried seeds by cold pressing and boiling respectively and chemical compositions were determined using Gas Chromatography (GC)-Mass Spectrometry (MS).

This paper reports the removal of fluoride ions in stored drinking water by a container made from chemically modified polyethylene material. To anchor triethylamine within the structure of the polyethylene material and improve its value, the polyethylene was first heated to melting. To the molten material, hot vegetable oil was added slowly with continuous heating followed by a strongly basic hydrogen peroxide solution then activated with triethylamine to produce a water insoluble material.

On Stability of Similarity Orbits

The notion of stability plays an important role in dynamical systems. It has been extensively studied in various forms. Various properties of stability have been proved under the underlying spaces.  

Kenya has an elaborate policy and regulatory framework guiding the establishment and management of private health insurance schemes run by non-state service providers. The private health insurance services are complimentary to services provided by the National Hospital Insurance Fund (NHIF) which is the body mandated by the Kenyan Government to provide the national insurance cover for all its citizens in an effort to spearhead universal health coverage.  

Aim: Countries have eased restrictions and in Kenya children have even been allowed back to school. Several parents still have fears about the health of their children as they go back to school after a long break occasioned by the COVID-19 outbreak. In this review, we aim to provide the immunological basis for our argument and thus opine that it’s safe to have the children in school.

An estimated two to three million annual deaths from Vaccine preventable diseases (VPDs) are preventable through immunization. Currently about 19.5 million infants miss out on routine immunization globally. We carried out a study on the role of caregiver characteristics in persuasive communication on adoption of routine immunization services. Further the moderating role of support systems was evaluated.

There is evidence that use of narrative messages is effective in the context of health. There is however no explanation as to what aspect of narrative leads to high level of persuasion.
