ABSTRACT This study sought to assess the impact of population growth on domestic water supply in Tunduma town, Tanzania. The study intended to assess the impact of population growth in domestic water supply, identify the challenges that hinder effective domestic water supply as well as determining mitigation measures to address limited access to domestic water supply at household level. Data were collected through household survey, key informant interviews and direct observation. A total of ...
ABSTRACT Low crop yields due to low erratic rainfall, high evapotranspiration, and deteriorating soil fertility in smallholder farmers‘ fields of sub-Saharan Africa have led to a quest for sustainable production practices with greater resource use efficiency. To alleviate water stress, soil fertility decline and reduce runoff, water harvesting technologies and integrated soil fertility management (ISFM) are alternative promising options whose impact on agricultural productivity are not yet ...
ABSTRACT In this work, an expert system for energy management in community based microgrid was developed. This was necessitated in a bid to address the inadequate power supply predominant in sub-Saharan African countries, while also addressing the problem of energy wastage that comes from individuals supplying their own energy demands. To achieve this, an architecture for a microgrid network was developed by adopting existing standards in the geographical region of interest. An energy...
Abstract This article describes the development of an acceptance sampling plan based on percentiles for Type-II generalized log-logistic distribution (TGLLD) introduced by Rosaiah et. al. [1]. The plan is developed by considering the lifetime percentiles as a variable and the life test will be terminated at a pre-specified time. The objective of the test is to determine the minimum sample size required to achieve a specific lifetime percentile at an acceptable level of consumer and producer r...
ABSTRACT Studies which link job satisfaction and workers‟ performance often, provide an inconsistent findings. Due to that, researchers directed this as an area that required more attention. This study, was out to investigate on the impact of job satisfaction on workers‟ performance by taking a case of Tanzania electric Supply Company limited (TANESCO), Dodoma Municipality. The work, was carried out by using a case study methodology and employed multiple methods in data collection and ana...
ABSTRACT Over the years, solid waste disposal in Ghana has become a major challenge to Metropolitan, Municipal and District Assemblies (MMDAs). As a result of urbanisation and increasing densities, Metropolitan Assemblies finds it difficult to deal with the large quantities of solid waste generated in their area of jurisdiction. This study investigated the nature of the urban solid waste situation in Cape Coast Metropolis, and the causes of the problem from the perspective of key stakeholders...
Abstract Integrated soil fertility management and soil water conservation practices are possible solutions to persistent soil quality decline and low availability of soil moisture which are affecting agricultural productivity in the dry lands of Tharaka-Nithi County. Nonetheless, the rate of uptake of these technologies and practices by smallholder farmers has stagnated over the years despite recommendations for their use. Lack of effective communication between the extension agents and rese...
ABSTRACT Introduction Childhood immunization is one of the most successful public health interventions worldwide. It has contributed enormously to public health including the eradication of small pox and near eradication of poliomyelitis. High immunisation coverage is vital in the control, elimination and eradication of vaccine preventable diseases which accounts for many childhood morbidities and mortalities worldwide. The introduction of the Expanded Programme on Immunization (EPI) has made...
Abstract In the earlier years, inventory management was treated as a cost Centre since purchasing department was spending money on materials, while store was holding huge inventory of materials, blocking money and space (Ramakrishna, 2005). However, with the process of liberation and opening up of global economy, there has been a drastic change in the business environment, resulting in manufacturing organizations exposed to intense competition in marketplace (Ramakri shna, 2005). In the UK, a...
ABSTRACTThis study is motivated by the fact that federal expenditure and money supply as a tool on the rate of unemployment. But to which extent, these instrument have contributed either to worsen the problem of unemployment or alleviate it.To investigate this problem, two hypotheses were formulated as follows.Ho: There is no relationship between money supply and unemployment.Hi: There is no relationship between federal expenditure and unemployme...
This paper outlines the evolution of additive manufacturing technology, culminating in 3D printing, and presents a vision of how this evolution is affecting existing global value chains in production. In particular, we bring up questions about how this new technology can affect the geographic span and density of global value chains. Potentially, wider adoption of this technology has the potential to partially reverse the trend towards global specialization of production systems into elements ...
ABSTRACT This study aimed at assesses the Challenges facing Dodoma Municipality in supplying water services in Dodoma Municipality was carried out in Kizota and Chamwino Wards. Specifically, the study focused on identifying issues and problem-related to accessibility in water supply; explore the institution's intervention to address the problem of water supply. Data were collected using different methods namely questionnaire surveys, interviews and Focus Group Discussions. A total of 96 res...
ABSTRACT Prices contain information crucial to maximizing the returns to production and marketing investments. At planting time, a farmer's planting decision depends on expected profits, which invariably hinge on the anticipated prices of the crop or mix of crops that would prevail in the market at the time of sale and on the farmer's interpretation of those prices. A trader, in search of profitable arbitrage, reads and translates price signals in deciding on what crops to buy, where to buy,...
Abstract: We have chosen the urine innurioglobulin M (IgM) as system to study glycoprotein biosynthesis and carbohydrate processing. Secreted IgM heavy chain (m) has five glycoasylation sites which location and structures have been determined. chain variable region (VH) ia involved in antigen binding, while the constant region (CH) is responsible for the effect or functions in which the carbohydrate plays an important role.
ABSTRACT Background: The health implications of infectious diseases affecting children of school going age as a result of low practice of personal hygiene practices and insufficient sanitary facilities in public primary schools is still a concern for worry in most poor and middle income countries. Objective: The objective of the study was to estimate the association between the sociodemographic characteristics and prevalence of hand washing with soap under running water practice among school...
