The fungus Leptosphaerulina persists in Anopheles gambiae and induces melanization

Abstract: Anopheles mosquitoes are colonized by diverse microorganisms that may impact on host biology and vectorial capacity. Eukaryotic symbionts such as fungi have been isolated from Anopheles, but whether they are stably associated with mosquitoes and transmitted transstadially across mosquito life stages or to subsequent generations remains largely unexplored. Here, we show that a Leptosphaerulina sp. fungus isolated from the midgut of An.gambiae can be stably associated with An. gambia...

The Role Of Human Right In Protecting Abused And Neglected Children, A Case Of Ilemela District Mwanza Region, Tanzania

ABSTRACT Research was based on the role of human rights in protecting abused and neglected children in ilernela district mwanza region in Tanzania. The number of children who die each year as a result of abused comes primarily from death registries or mortality data.young children are at greatest risk, with rates for the 0—4 years old age group more then double those of 5—14 year of age. However, despite the role of human rights in protecting abused and neglected children , the numbers of...

An Assessment of the Level of Women’s Participation in SMEs Management in Urban Zimbabwe: A Focus on Harare 2012 to 2017

ABSTRACT  The purpose of the study was to assess the level of women’s participation in SMEs management in Harare, Zimbabwe. The study used mixed research design in which both qualitative and quantitative approaches were employed. The study area was conveniently based on the geographical location, and in each location, businesses with women or owned by women were purposively sampled as the research demanded. The sample was made up of 184 women entrepreneurs in Harare. Individual factors hav...

Assessment of Morphological, Nutritional And Cytological Characteristics of Some Nigerian Cucurbita Species

ABSTRACT   Two field experiments were conducted in 2007 and 2008 cropping seasons at the Department of Crop Science research farm, University of Nigeria, Nsukka, to characterize some Nigeria cucurbita genotypes with respect to morphology, nutrient composition and the cytology. The results obtained showed that Shannon diversity index (Hs) was 4.136 which suggests high level of diversity among the Nigerian cucurbita species evaluated. Cucurbita moschata had the highest Shannon diversity index...

Phylogenetic and morphological diversity of culturable cyanobacteria from Lake Magadi in Kenya

Abstract Lake Magadi is an alkaline saline Lake in Kenya, which lies on the Great Eastern Rift valley. Although the lake is characterized by extremes of salt, pH and temperature, it supports diverse groups of cyanobacteria. In this study, we used different media to isolate novel groups of cyanobacteria. We recovered 11 isolates affiliated to the orders Chroococcales, Oscillatoriales, Pleurocapsales and Nostocales. Isolates affiliated to Chroococcidiopsis species had similarity values below 9...

Diversity, distribution and abundance of potential rift valley fever vectors in Baringo County, Kenya

Abstract/Overview Abstract Rift Valley fever (RVF) is a zoonotic disease that occurs sporadically in form of outbreaks and is transmitted by diverse mosquito species in different geographic regions. Knowledge on diversity, distribution and abundance of RVF vectors is useful for risk assessment of RVF outbreaks. Diversity, distribution and abundance of RVF vectors from four ecological zones in Baringo County were studied. Four potential RVF vectors, namely Mansonia uniformis; Mansonia afri...

Migrancy and Diaspora Identities in Chika Unigwe's On Black Sisters' Street and Chimamanda Ngozi Adichie's Americanah

One of the major challenges of postcolonial African literature has been its transnational shift in the age of globalization. Globalization with its attendant increase in migrations continues to witness an influx of human beings from diverse parts of the world into Europe and America. Predictably, the largest numbers are often from the less developed countries of the world. The outcome of these  movements has been transformations and integrations in different ways. It is on this premise that ...

Factors Affecting Transition, Performance And Retention Of Girls’ In Secondary Schools In Arid And Semi Arid Land: A Case Of Rhamu Town - Mandera County, Kenya

ABSTRACT This study aimed at gaining an in-depth understanding of the factors affecting educational access, retention and performance. Although a number of studies have been done on factors affecting access, performance and retention in secondary schools in other parts of the Country, no specific study has investigated the continued inaccessibility and low retention among the girl child in secondary schools in ASAL regions particularly in Mandera District in Kenya in spite of free secondary ...

NEXUS BETWEEN NATIONAL ELECTIONS AND INTER-ETHNIC CONFLICTS IN NAKURU COUNTY, KENYA BETWEEN 1992 AND 2017

Abstract Wars and conflicts determine political boundaries, disperse populations, shape political discussions, and have far-reaching effects on all aspects of human societies. The use of violence is common and can be mobilized for many ends, including but not limited to electoral success. An unstable political climate has persisted in areas with a diverse ethnic makeup ever since the multiparty system was introduced in 1992. This study sought to assess the nexus between national elections an...

Computational Methods in Historical Research

The Humanities primarily deal with the human condition and its various manifestations and dimensions. Now, the human experience is rich, diverse and complex. It involves the whole human experience from the distant pre-historic past when man used to live in the cave until the present day where he now goes to space and is technologically advanced. The arts and humanities basically analyze the human phenomenon and in the process of doing this, there is a need for the scientific methodology.  �...

Geographic dispersion of invasive crop pests: the role of basal, plastic climate stress tolerance and other complementary traits in the tropics

Abstract: Global pest invasions have significantly increased in recent years. These invasions together with climate warming directly impact agriculture. Tropical climates feature extreme weather events, including high temperatures and seasonal droughts. Thus, successful invasive pests in tropics have to adapt to these extreme climate features. The intrinsic factors relevant to tropical invasion of insects have been explored in many studies, but the knowledge is rather dispersed in contempora...
