Abstract Synthetic sex pheromones could provide valuable alternative means of pest control in Integrated Pest Management (IPM) strategies. Their uses could include population monitoring with pheromone traps to guide other control methods, by mass trapping and mating disruption. (Z)-ll-Hexadecenal (Z-11-C4Hg CH=CH (CHZ) 9 CHO) and (Z)-llhexadecen- l-ol (Z-ll-C/H",CH=CH(CH1 )oCH10H), the major components of '1 £ J £. spotted stalk borer, Chilo pert el Lue (swinhoe) fernale sex pheromone, were...
ABSTRACT Vihiga County for a long time has been known to be an endemic malaria region. The presence of many rivers and high temperatures, is ideal for mosquitoes breeding and maturity. However, the impact of changing climate and increasing malaria prevalence in the region have received little attention. Temperatures have increased over the past decades and rainfall decreased. Mosquitoes are temperature sensitive whereby high temperatures exacerbate their breeding. Therefore, this study aimed ...
Abstract Kenya is one of the major contributors to the poor maternal health status in Africa with maternal mortality ratio of 488 maternal deaths per 100,000 live births translating to 7,700 maternal deaths annually [23]. There are regional disparities in maternal mortality among the 47 counties with county with the highest maternal mortality has almost 20 times maternal deaths of that with the lowest. Migori County is one of the counties with the highest burden of maternal mortality in the c...
ABSTRACT; Amritphala (psidium guajava l) is a small size tree in myrtaceae family, traditionally used in treatment of several diseases such as inflammation, diabetes, hypertension, wounds, pain and fever. When it comes to skin care, the astringents of guava enhance the skin texture and tighten loosened skin. The guava leaves works more effectively than any other skin nourishing lotions in the market. Decoction of immature leaves and fruits can be applied on the skin to prevent tightening and ...
ABSTRACT A birth certificate is becoming one of the crucial documents a Kenyan must possess. For instance, it is becoming a requirement for standard eight pupils and form four students to produce a birth certificate, in which a copy will be send to Kenya National Examination Council, for them to be registered as candidates. Similarly, most institutions require a birth certificate for identification purposes if one is not an adult also when processing identification card you have to produce th...
ABSTRACT Information and knowledge play an important role in enabling rural women to achieve economic empowerment through poverty alleviation. The general aim of this study was to determine the contribution of information in the empowerment of rural women. In a bid to achieve this objective, the study sought to assess the roles of information in increasing women access and control of economic resources, in assisting women contribute towards economic decisions at the household and community le...
ABSTRACT Entanglement is a fundamental feature of quantum mechanics which originated from the 1935 paper of Einstein, Podolsky and Rosen (EPR) and has been demonstrated in many quantum systems for development of quantum technology. Entanglement of photons occurs through polarization states generated in nonlinear parametric processes. The Optical parametric oscillator (OPO) constitutes a nonlinear process in which a pair of entangled photons (signal and idler) is generated when a light mode fr...
ABSTRACT Various energy sources are utilized at present with a challenge of energy storage in many cases. The existing rechargeable storage batteries which include sodium-ion and lithium-ion have some limitations in their gravimetric capacities. This can be improved by incorporating Vanadium disulphide (VS2) due to its metallic properties at ground state. In this work we investigate the adsorption of lithium ions on the VS2 layered material. Research shows that intercalating lithium ions on a...
ABSTRACT The demand for agricultural land is driving the conversion of moist Kenyan savannah into agroecosystems (grazing fields and croplands) and together with altered rainfall patterns, is likely modifying soil moisture, soil respiration and carbon store in the ecosystem. Nevertheless, the carbon dynamics of moist savannas plus of the converted ecosystems are poorly understood yet planning for sustainable use of the ecosystem need to be based on scientific knowledge. While previous studie...
Abstract ICT tools are continuously changing business processes while the Zimbabwe’s public health sector still lags behind. The commercial industry has completely evolved because of eCommerce business models but an e-Health strategy has not yet been implemented in the health sector. The need for a tool to track the areas in the country with critical shortages of public health care professionals and ease manipulation of health practitioner’s data stirred the development of the National H...
ABSTRACT Chipinge Town Council Building Inspection system is an online software that manages, queries and inspection of stands to the Chipinge residents. The system allow clients to book, request for inspection, receiving the response online whilst the housing director is able to assign Inspectors tasks and there is generally improvement on the interaction between the clients and the Town Council through online communication that is facilitated by sending and receiving queries. The system wa...
ABSTRACT Of all the uses of African plants, the aspect of medical use has probably attracted the most attention and has also been the most complex and varied. Nearly 70,000 species of higher plants have been used for medical purposes world wide. Medicinal plants form the key component to traditional medicine which remains the major source of health care for over 70% of the Kenyan population. Over 90% of the population use medicinal plants at one time or another. The increasing need to develop...
Abstract Preliminary validation of the extracts for bioactivity revealed that the n-hexane, DCM and MeOH extracts of the stem bark of L. eriocalyx were active against P. falciparum, A. gambie larvae, B. anthracis, and A. niger. This formed the the basis of fractionation of these crude extracts whereby lupeol (27), quercetin (65), apigenin (68) friedelin (133), -sitosterol (134), lupenone (135), -sitosterol-3-O-glucoside (136), chrysin (137) morinhydrate (138), quercetin-3-O-glucoside (1...
ABSTRACT Malaria rapid diagnostic tests (RDTs) are a great achievement to the implementation of parasite based diagnosis before treatment. They use a nitrocellulose strip coated with antibodies that target the Plasmodium antigens; histidine rich protein II (HRP2), lactose dehydrogenase (LDH), and aldolase. A major drawback of the method is that the majority of RDTs do not have positive control materials to test different batches of RDTs at the point of care. Dried Plasmodium-infected samples ...
ABSTRACT Tamarindus indica l leaves extract was evaluated against six bacterial strains (2 Gram-positive and 4 Gram-negative) known to cause food spoilage. Functional groups of Tamarindus indica l leaves were evaluated using the Fourier transform infrared (FTIR) spectroscopy. The leaves were extracted by the Soxhlet extraction using aqueous and organic solvents (acetone, ethanol and methanol). Stock solution of the extracts was prepared by dissolving 0.8g of each extract in 2ml dimethyl sul...
