Abstract Evaluation of customer satisfaction differs from one study to another. Studies have been differing with their focus and coverage. Most of studies focused on evaluating factors influencing customer satisfaction or associate customer satisfaction and quality of services. This paper used logistic regression to develop customer satisfaction model for Precision Air. Five dimensions or variables have been considered: on time performance; aircraft safety; schedule integrity; on board servi...
Abstract We perform a detailed physical analysis for a class of exact solutions for the Einstein-Maxwell equations. The linear equation of state consistent with quark stars has been incorporated in the model. The physical analysis of the exact solutions is performed by considering the charged anisotropic stars for the particular nonsingular exact model obtained by Maharaj, Sunzu and Ray. In performing such an analysis we regain masses obtained by previous researchers for isotropic and anisotr...
We describe a novel and cost-effective method to enhance the photo-conversion efficiency of blended PbI2/TiO2 perovskite photovoltaic cells by pre-annealing the constituent film components during the fabrication. This approach is also unique because it does not presume a strictly controlled fabrication environment. The average conversion efficiencies of the cells of the final devices were observed to rise from 6.6% to 10.8% for annealing temperatures of 60 ◦C to 100 ◦C, respectively. Anne...
ABSTRACT Multiple choice examinations are commonly used to assess student learning. However, instructors often find it challenging to write good items that ask students to do more than memorize facts and details. Multiple choice test items are generally more complex and time-consuming to create than other types of tests. It requires a certain amount of skill. However, this skill may be increases through study, practice and experience. This dissertation discusses a number of issues related to...
ABSTRACT This study aimed at investigating the contribution of teaching aids (counting objects) in numeracy skills performance for standard two pupils. The main objective of this study was to introduce an effective intervention for enhancing pupils‟ achievement levels in numeracy. The study revealed that there is a low numeracy skill which is caused by many reasons such as unsuitable teaching and learning environment, few teaching methods, negative attitude of pupils and parents towards nu...
ABSTRACT This dissertation reviews numerical solution of parabolic partial differential equations. A short description and classification of parabolic partial differential equation is presented. The explicit, implicit and Crank-Nicolson numerical techniques are discussed in relation to consistency, convergence and stability. Analytical and numerical solutions of well-posed problem are obtained by Crank- Nicolson and Laplace transform methods, and discussed through a practical example. Simulat...
Abstract Introduction Cultivation of spirulina at commercial-scales relies on analytical grade–based media, which are expensive and so are the product. Purpose This study assessed the biomass, proximate composition, and other useful compounds in Spirulina (Arthrospira fusiformis) produced with a cost-effective culture medium (LCMA), and the results were compared with those from a standard Zarrouk medium– grown spirulina. Methods The LCMA medium was formulated by using a commercial NPK10-2...
ABSTRACT The overall goal of this research work was to develop and validate an e-Learning adoption model in Tanzanian secondary schools as literature had not revealed any comprehensive model that is specifically used in determining the adoption of e-Learning in Tanzanian secondary schools. The existence of this gap encouraged the carrying out of this research to empirically test and validate the combination of the Technology Acceptance Model (TAM), Task Technology Fit (TTF) and Technology Rea...
ABSTRACT This project research titled “Design and Implementation of an Online Journal Management System which is a case study of Sokoto International Journal of Counselling Psychology (SIJCP)” is a web-based system which is aimed at using the potent ability of the Computer System to solve many of the challenges faced by the current manual system of Journal and Publication processes. It provides numerous benefits which include: Automation of the Submission process, review process, payment ...
ABSTRACT Water is one of the fundamental element for life. For that reason, water usage forecasting is required for a proper planning and management. Because there is no single methodology that is used to forecast water demand (quantity of water to be used) across the world, this study intended to develop a statistical model for household water usage in Dodoma Municipality. Longitudinal and cross-sectional research design data from DUWASA, NBS and 395 households connected with piped water wer...

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...
