ABSTRACT Men‘s involvement in maternity care has been recognized as one of the key strategies in improving maternal health and accelerating reduction of maternal mortality. Men impact women‘s reproductive health through their role as partners, fathers and close family providers in terms of financial power and decision control they have. Factors that determine men‘s involvement in maternity care have been documented in other parts of the globe, but very little research has been conducted...
Abstract Radio frequency spectrum scarcity has become a high priority research area over the past few years. The huge increase of network subscribers with multimedia applications coupled with underutilization of radio frequency spectrum motivates the search for other measures to address the scarcity of radio frequency spectrum. This work investigates on a price based spectrum sharing scheme for connection-oriented traffic in wireless cellular networks as a solution to address the scarcity of ...
ABSTRACT We find new exact solutions to Einstein-Maxwell field equation for neutral anisotropy stellar stars with Van der Waals equation of state. We adopted Sunzu, Maharaj and Ray‘s metric function and measure of anisotropy. The solutions are obtained after considering the transformed Einstein-Maxwell field equations for neutral anisotropic matter. In our models, we regain previous anisotropic and isotropic results as a special case. We consider the space-time geometry to be static spheric...
Abstract: Cashew nut shells (CNS), which are agro wastes from cashew nut processing factories, have proven to be among the most versatile bio-based renewable materials in the search for functional materials and chemicals from renewable resources. CNS are produced in the cashew nut processing process as waste, but they contain cashew nut shell liquid (CNSL) up to about 30–35 wt. % of the nut shell weight depending on the method of extraction. CNSL is a mixture of anacardic acid, cardanol, ca...
Abstract Background Despite significant improvement in prevention and control over the past decades malaria remains a significant public health concern in Tanzania with 93% of the population being at risk. To prevent malaria infection and promote malaria free zones, understanding the community’s knowledge, attitudes, and practices toward malaria control are essential. This study therefore aimed at determining the levels of understanding, and attitudes, as well as socio-cultural aspects...
Abstract Twenty Concrete Blocks from (20) different Local Governments in Katsina state was measured using Gamma Ray Spectroscopy with NaI (TL) detector. Three naturally Occurring Radionuclides and their activity concentrations were determined, are 40K 226Ra, and 232Th. Their activity Concentrations ranges from 40K 46.11 ± 826.59 to 46.11± 8.55 Bq/kg, (226Ra) ranged from10.19 ± 2.43Bq/kg to 75.09 ± 4.98 Bq/kg and (232Th) ranged from 2.77 ± 9.59Bq/kg to 123.49 ± 9.35Bq/kg respectivel...
Abstract Contamination of complementary foods by aflatoxin is a serious public health threat that requires attention to ensure that proper actions are taken to limit its health effects. A cross-sectional study was conducted to assess parents’ practices and barriers associated with reducing aflatoxins contamination in complementary foods among parents with children aged 6-23 months in central regions of Tanzania. Semi-structured questionnaire (364) respondents and focus group discussion (FG...
ABSTRACT Theses and dissertations are among the most important sources of valid detailed information on a particular subject on which researchers conduct widespread research work. This study aimed at developing and evaluating an online electronic theses and dissertations system. The University of Dodoma was used as a case study for this dissertation. A mixed approach data collection method was used effectively in this study. Several literatures were reviewed so as to identify challenges that ...
ABSTRACT This research investigated the impact of network topologies on the performance of OpenFlow protocol. OpenFlow Protocol is a southbound protocol over Secure Socket Layer (SSL) in Software Defined Networking (SDN). SDN architecture separates the intelligence (decision making) part (control plane) of network devices from forwarding capability (data plane). OpenFlow protocol is the communication protocol for exchanging control messages between control plane and data plane. The research i...
ABSTRACT The potentials of Saw dust, Rice husk and Groundnut shells were investigated for bioethanol production. The substrates were pretreated using 2%, 4%, 6% and 8% solution of dilute H2SO4 and HCl. The pretreated substrates were thermally treated at 1050C in order to detoxify them. The pretreated substrates obtained using different concentrations of acids were fermented using Saccharomyces cerevisiae (Yeast). The results show that Rice husk treated with 4% H2SO4 (2.689%dryweight) has...
ABSTRACT The foundation of educational development of any country through all ages has been focusing on the quality basic education from which the primary school pupils’ academic performance is of greatest interest. Basing on its important, this study was conducted in order to develop a model for the primary school pupils’ academic performance in Tanzania. The study employed panel longitudinal research design. Secondary data that were used in the study were collected from the President�...
Abstract In this dissertation, we generate solutions to Einstein-Maxwell field equations devoted to neutral anisotropic stellar objects using linear equation of state. The field equations are transformed by adopting Bannerji and Durgapal transformation. We generated the solutions to Einstein field equations and obtain matter variables and gravitational potentials by using the general differential equation governing the model. In our model, isotropic results are regained as a special case. Th...
ABSTRACT Software-Defined Network (SDN) is a new and booming network paradigm that promises to improve network performance. This is achieved by the separation of the control plane and the data plane. The traditional network faced a lot of challenges particularly on how to improve network performance, manual configurations of the network devices, and many more others. SDN overcome all these challenges by introducing the SDN controller that controls the entire network. This research work studie...
Abstract The advancement of wireless and mobile technologies has given rise to the mobile government (m‐Government). A new channel of public service delivery using a mobile phone. In Tanzania, several m‐Government initiatives have been undertaken. Among these, some can be said to have succeeded while others are still struggling. The reasons for these variations are not known. This study aimed to capture the critical success factors (CSFs) for the adoption of m‐Government and propose a f...
