Utilization Of Dramatic Elements In Delineating Human Interaction In Selected Drama Of Francis Imbuga And John Ruganda

ABSTRACT This study focuses on the utilisation of dramatic elements in the delineation of human interaction in six plays of Francis Imbuga and John Ruganda. The study is motivated by the perceived lacuna in the body of knowledge on the utilization of dramatic elements in the rendering of this thematic concern in the selected plays of Imbuga and Ruganda. The study seeks to investigate the intersection between dramatic elements and the way relationships in the society are presented in the six s...

Dominant Power Politics and Democratic Consolidation in Zimbabwe Circa 1980-2017

This paper examines issues in principles and practices of democratic consolidation in Zimbabwe. The political system in Zimbabwe theoretically upheld a multiparty system and has held periodic elections since 1980 but undermined reforms that could have put democracy and politics on a progressive trajectory. This is not peculiar to Zimbabwe alone but is a general political culture on the continent. Gleaning on evidence from diverse sources, the paper finds that the separation of powers in Zimba...

Mapping cetacean distribution using citizen science in the Western Cape South Africa

Abstract: The Western Cape is a unique area to undertake research, due to the varying oceanographic conditions along the coast. These diverse environments create a hotspot for cetacean presence and diversity. This study aimed to collate and map distribution information of local whale and dolphin species in the Western Cape using citizen science. The first data chapter focused on obtaining opportunistic sightings from water users from scientific, platform of opportunity and sporadic sighting ...

Arboviruses and blood-meal sources in zoophilic mosquitoes at human-wildlife interfaces in Kenya.

Abstract: Background: Zoophilic mosquitoes play an important role in the transmission of arboviruses of medical importance at human-wildlife interfaces, yet arbovirus surveillance efforts have been focused mostly on anthropophilic mosquitoes. Understanding the diversity of zoophilic mosquitoes and their associated feeding patterns and arboviruses can inform better vector control strategies. Materials and Methods: We morphologically identified mosquitoes collected from two game reserves in Ke...

Tsetse blood-meal sources, endosymbionts and trypanosome-associations in the Maasai Mara National Reserve, a wildlife-human-livestock interface

Abstract: African trypanosomiasis (AT) is a neglected disease of both humans and animals caused by Trypanosoma parasites, which are transmitted by obligate hematophagous tsetse flies (Glossina spp.). Knowledge on tsetse fly vertebrate hosts and the influence of tsetse endosymbionts on trypanosome presence, especially in wildlife-human-livestock interfaces, is limited. We identified tsetse species, their blood-meal sources, and correlations between endosymbionts and trypanosome presence in ts...

Pathogens, endosymbionts, and blood-meal sources of host-seeking ticks in the fast-changing Maasai Mara wildlife ecosystem

Abstract: The role of questing ticks in the epidemiology of tick-borne diseases in Kenya’s Maasai Mara National Reserve (MMNR), an ecosystem with intensified human-wildlife-livestock interactions, remains poorly understood. We surveyed the diversity of questing ticks, their blood-meal hosts, and tick-borne pathogens to understand potential effects on human and livestock health. By flagging and hand-picking from vegetation in 25 localities, we collected 1,465 host-seeking ticks, mostly Rhip...

Different Plant Viruses Induce Changes in Feeding Behavior of Specialist and Generalist Aphids on Common Bean That Are Likely to Enhance Virus Transmission

Abstract: Bean common mosaic virus (BCMV), bean common mosaic necrosis virus (BCMNV), and cucumber mosaic virus (CMV) cause serious epidemics in common bean (Phaseolus vulgaris), a vital food security crop in many low-to-medium income countries, particularly in Sub-Saharan Africa. Aphids transmit these viruses “non-persistently,” i.e., virions attach loosely to the insects' stylets. Viruses may manipulate aphid-host interactions to enhance transmission. We used direct observation and ele...

Contribution of Different Aquatic Habitats to Adult Anopheles Arabiensis and Culex Quinquefasciatus (Diptera: Culicidae) Production in a Rice Agroecosystem in Mwea, Kenya

Abstract: Studies were conducted to determine the contribution of diverse larval habitats to adult Anopheles arabiensis Patton and Culex quinquefasciatus Say production in a rice land agro-ecosystem in Mwea, Kenya. Two sizes of cages were placed in different habitat types to investigate the influence of non-mosquito invertebrates on larval mortalities and the contribution of each habitat type to mosquito productivities, respectively. These emergence traps had fine netting material covers to ...

Fungal Endophyte Communities of Crucifer Crops Are Seasonally Dynamic and Structured by Plant Identity, Plant Tissue and Environmental Factors

Abstract: Endophytic fungi are important in diverse plant functions but knowledge of the factors that shape assemblages of these symbionts is lacking. Here, using a culture-dependent approach, we report 4,178 endophytic fungal isolates representing 16 orders isolated from stems, roots and leaves of three cruciferous plant species, Chinese cabbage (Brassica rapa L.), radish (Raphanus sativus L.) and white cabbage (B. olerocea L.), collected from 21 focal fields with different landscape contex...

GENOTYPE x ENVIRONMENT INTERACTION AND STABILITY OF RELEASED STRIGA RESISTANT SORGHUM [Sorghum bicolor (L.) Moench] GENOTYPES IN ETHIOPIA

Abstract: The yield performance of sorghum cultivars is highly influenced by environmental factors and genotype x environment interaction; therefore interaction is the major concern to plant breeders to develop improved cultivars. Field experiment was conducted to evaluate striga resistant sorghum genotypes during the 2014 cropping season at Fedis,Meiso, Kobo,Pawi and Humera. The materials used in the study consisted of eight striga resistant sorghum genotypes representing the types widely g...

THE ADEQUACY OF THE SHIELDING MATERIALS AND TECHNIQUES EMPLOYED AT SELECTED X-RAY CENTERS IN IBADAN

X-rays play a vital role in medical diagnosis and therapy. Exposure to radiation can however cause a variety of biological mutations. The effects of exposure to radiation could be as severe as leading to rapid death when the whole body is irradiated with large doses. They could also be so minimal and almost negligible for a variable period of time after low doses until delayed effects of radiation manifests in a group of the exposed individuals. As a result, x-rays pose a threat to the safety...
