ABSTRACT: Background: Mobile money is becoming important in the context of payment services where is used in many of developing economies and Zanzibar has no exception. This study analyzes challenges facing the people in accessing mobile money services in urban district Zanzibar. Materials and Methods: The researcher has mainly employed quantitative research approach with appropriate method of analysis for this study. The sample size for this study consists of 100 mobile customers from Zantel, Tigo, Halotel and Airtel in Urban district in Zanzibar and survey questionnaire was used as data collection instrument. To achieve a credible study, descriptive statistical techniques were used to analyse the collected data from relevant respondents.......

ABSTRACT: Background: The Study is based on mathematical modelling of biofluids using the fundamental physical principles of fluid flow such as mass is conserved, Newton's second law and energy is conserved. These principles are used in the derivation of the blood flow models under consideration.The problem is investigated by using two different fluids. The result for resistance to flow across the length of the artery is obtained. Materials and Methods:A mathematical model of a generalized Power-law blood and Casson-fluid flow through a stenosed artery is considered. This mathematical model is proposed and analyzed by studying the non-Newtonian flow of blood through a constricted (a diseased or stenosed) arterial segment. The solution of the models was obtained by direct integration........

ABSTRACT: Background: With digitization and the spread of smartphones, mobile apps have become significantly more relevant in recent years. Research into the acceptance of mobile apps as a technology often focuses on the application of the Technology Acceptance Model (TAM). Nevertheless, there are some examples in the research that do not apply the TAM and help to identify new factors and thus improve mobile app research. Materials and Methods: This essay discusses the TAM, as a model that focuses primarily on the technologies themselves. It then presents examples of research results from the context of mobile apps that do not apply the TAM........

ABSTRACT: As computing is increasing pervasively, the energy consumption attributable to computing is climbing, despite the clarion call to action to reduce consumption and reverse greenhouse effects. Green computing can be defined as the study of designing, engineering, and manufacturing, using and disposing of computing devices in a way that reduces their environmental impact. The topic of this paper, Green Computing is especially important in this regard. Green computing is a very hot topic these days, not only because of rising energy costs and potential savings, but also due to its impact on the environment. This paper outlines the goals, reasons, approaches, methodologies andemphasizes the importance of green computing for sustainable development.
