ABSTRACT Solar thermal energy storage technology has made solar energy a potentially viable supplement for fossil fuels in much of the developing world. However one of the challenges in adopting the technology is the low efficiency of the storage media. Many thermal energy storage materials have difficulties and limitations such as handling, containment, storage and cost. Sand which is abundant, cheap, easy to handle and contain, can be used to alleviate the difficulties. Research carried out...

A huge number of studies have been done supporting seamless mobility networks and mobile technologies over the years. The recent innovations in mobile technologies have unveiled another revolution from the static architectural approach for client-server network relationships to more dynamic, and even mobile approaches. Due to the special equipment and infrastructure needed to support network mobility management, it is difficult to deploy such networks beyond the local network coverage witho...
Agriculture forms the backbone of Kenya's economy contributing 30% of the country's GDP. However, little is known about the prices, supply and demand of fruits and vegetables. Market price information is a very important agricultural concern which can be enhanced by big data and machine learning techniques like predictive analytics. This research work was based on developing an agricultural commodity price prediction application that uses a machine learning model on appropriate data to facili...
Internet of Things has been described as a system of related computing devices, machines, animals or people that are provided with unique identifiers to capture and transfer data over a network without requiring human intervention or human-to-computer interaction. It has been used in several fields such as surveillance, tracking and weather forecasting. Weather forecasting is the process by which the state of the atmosphere and the weather conditions are predicted for some future period. Weat...
Small and Medium Enterprises (SMEs) face numerous challenges in identification, setting up and making use of Information Technology (IT) as an enabler for business. Cloud computing could solve this problem by offering ready, low cost of entry IT solutions. Adoption of cloud computing among the SMEs in developing countries is however low due to a number of barriers as identified by previous studies. Over the years, research on adoption on innovation and technology has unveiled a number of theo...
The main objective of this project is to improve the MPESA authentication process through the incorporation of a voice biometric functionality that enables the remote control of the individual MPESA accounts by MPESA subscribers with higher efficiency, accuracy and a higher level of authentication. The voice biometric is a state of the art technology that factors in authentication with better usability with the aim of combating fraud, self-service empowerment and cost savings through proper u...
ABSTRACT Gender mainstreaming was endorsed as a global strategy for promoting gender equality in the Beijing Declaration and Platform for Action in 1995. Although the government of Tanzania has taken measures to mainstream gender in government institutions, such mainstreaming is little investigated in the workplaces of NGOs. This study was conducted in Ilala Municipality in Tanzania to assess implementation of gender mainstreaming in the workplace of NGOs. Cross-sectional research design was...
This is hospital based analytical retrospective case control study was conducted at Soba university hospital, Omdurman military hospital, Omdurman maternity hospital (Khartoum state), and Sudan university of science and technology-college of medical laboratory science, during the period from September 2016 to February 2017. The study was aimed to detect beta-catenin expression in ovarian tumors, using immunohistochemistry. Forty paraffin block samples were collected from patients previo...
A number of prothrombotic and fibrinolytic disorders may lead to venous thromboembolism(VTE). Venous thrombo embolism(VTE) includes deep vein thrombosis (DVT)and pulmonary embolism(PE).The disease is caused by many factors some of which are congenital and others are acquired. A 4G/5G polymorphism located in the promoter region of plasminogen activator inhibitor-1 (PAI-1) gene has been found to be commonly associated with the high levels of PAI-1 and might be a risk factor for deep vein...
ABSTRACT Milk is an important part of the diet among pastoral communities in Kilosa district, Tanzania. Its production and consumption derives much food security and economic benefits to the rural people in the district. However, Milk has a complex biochemical composition and its high-water activity and nutritional value serves as an excellent medium for growth and multiplication of many kinds of microorganisms. This shortens the shelf-life of milk. In the framework of research to improve th...
