EXTENDED ABSTRACT Urban Agriculture is crucial to the supply of food especially fresh vegetables in many urban areas including Dar es Salaam in Tanzania. In addition to the supply of food, it serves as a source of employment and income for many urban dwellers. However, the intensive and continued growing of vegetable on same piece of the land tend to trigger enormous pests pressure of diverse species which calls for the most effective and robust pest management practices. As such, most urban...
Abstract: This study investigated the impact of larval management and the temporal variation in larval productivity in Eritrea, a semiarid ecosystem. Results of this study show that mosquito breeding persists throughout the year mainly in stream bed pools. Anopheles arabiensis production in the ephemeral natural aquatic habitats such the streambed pools was high throughout the year and negatively associated with rainfall (r −0.288, P 0.047). High densities of An. arabiensis larvae were als...
ABSTRACT Predator-prey models describe the interaction between two species, the prey which serves as a food source to the predator. The migration of the prey for safety reasons after a predator attack and the predator in search of food, from a patch to another may not be instantaneous. This may be due to barriers such as a swollen river or a busy infrastructure through the natural habitat. Recent predator-prey models have either incorporated a logistic growth for the prey population or a time...
Abstract Background: Hypertension is a common non communicable condition worldwide. In developing countries (including Nigeria), the use of complementary and alternative medicine (CAM) is common. This study investigated the frequency and factors associated with use of CAM among hypertensive subjects in an urban Nigerian community. Perspectives about the management of hypertension were obtained from CAM practitioners in the community. Methods: Four hundred and forty hypertensive subjects in ...
ABSTRACT Great progress has been made over the past decades with respect to the application of genetic engineering to increase food supply and to generate nutritionally improved food crops. The role of genetically modified (GM) crops for food security is the subject of public controversy. Genetically engineered crops could contribute to food production increase and higher food availability. They also impact on food quality and nutrient composition. This work discusses the challenges of food i...
Abstract For the purpose of comparison of the traditional statistical methods used in analysing and classifying data with a vast amount of information and modern statistical methods computerized to obtain relationships and models that help in extracting useful information and support for decision making and hence the problem of study in how Employing this field in the organization, analysis and classification of such a large amount of data, and the establishment of a general rule concerning ...
ABSTRACT Food security is a major concern of the world, especially among the poor in developing countries. Pulses, including dry beans, play a crucial role in ensuring food security, particularly in Sub-Saharan Africa where over 200 million people depend on beans as part of their main diet. In Rwanda, dry beans are an important staple food and constitute the primary source of protein for about 90% of Rwandan households. Unfortunately, dry beans are a slow-cooking food, requiring a lot of time...
ABSTRACT This project presents a 40A maximum power point tracking solar charge controller. The MPPT charge controller tries to keep the voltage and the power stable. The MPPT charge controller will harvest more power from the solar array – it will adjust its input voltage to harvest the maximum power from the solar array and then transform this power to supply the varying voltage requirement of the battery plus load. An MPPT charge controller is an electronic DC to DC converter that optimi...

ABSTRACT The environment harbours many bacterial species, some of which include non-tuberculous mycobacteria which have recently become important in public health. Isolation of mycobacteria from the environment has not been easy because of the presence of other fast growing bacteria and fungi. For isolation of mycobacteria from the environment, decontamination methods that minimize contamination but maximize recovery of mycobacteria are needed. This study sought to compare three decontaminat...
Abstract Over the years, Namibia continue to experienced rapid growth of unemployment. The purpose of this study is to investigate the effects of government expenditure and money supply on unemployment in Namibia. The annual data employed in the study covered the period from 1980 to 2018. The study applied the ARDL or bound cointegration approach which is said to be more appropriate for the estimation of small sample studies and variable combination of the order of integration (I (0) and I (1...

ABSTRACT The study examined the impact of money supply on economic growth in Nigeria. In the model specified, real gross domestic product (real GDP) is the regress while broad money supply, real exchange rate, and real interest rate are the regressors. Data was collected from CBN statistical Bulletin for the period 1981 – 2010. The statistical techniques used for the analysis is the ordinary least square techniques with the aid of Stata 10 software package. The research indicates that real ...
ABSTRACT Access to quality water remains a key indicator of an improved social and economic life of any community. Due to an increasing human population, changes in land use activities and climate variability, Nyangores Basin in Kenya has been under pressure and for this reason, availability and access to quality and sufficient quantity of water has been adversely affected. Despite government plans to ensure all households access piped water; this has not been achieved as coverage is still v...
