Water Leakage Detection System Using Arduino

Clean water is a scarce resource for the human life and is subject to wastage due to leakage of the distribution pipes in large cities. Water pipe leakage is a big problem around the world of which most of the water distribution authorities faces difficulties to detect the location of the fault. This problem of leakage can be caused by several factors such as breakage of the pipelines due to aging or ongoing constructions in urban cities like Dar es salaam, consequently due to that case, the distribution authorities face hardship to identify the cause and enable them to take action. Therefore, the aim of this project was to develop an IoT-based system for water leakage detection. The prototype was developed comprising two sensors embedded at the source and destination points to measure the flow rate of water. The result indicated that the volume of water generated at the start point can be compared with the other end to determine if there is any leakage. A greater focus on distance calculation could produce interesting findings that account for more research on IoT monitoring systems.

Antimicrobial usage in cattle and poultry production in Dar es Salaam, Tanzania: pattern and quantity

Background Antimicrobials are extensively used in cattle and poultry production in Tanzania. However, there is dearth of information on its quantitative use. A questionnaire-based cross-sectional study was conducted from August to September 2019 in randomly selected poultry and small-scale dairy farms, in three districts of Dar es Salaam City eastern, Tanzania, to assess the practice and quantify antimicrobial use. Descriptive and statistical analyses were performed at a confidence interval of 95%. The ratio of Used Daily Dose (UDD) and Defined Daily Dose (DDD) were used to determine whether the antimicrobial was overdosed or under dosed. Results A total of 51 poultry and 65 small-scale dairy farms were involved in the study. The route of antimicrobial administration was 98% orally via drinking water and 2% in feeds for poultry and for small-scale dairy farms, all through parenteral route. Seventeen types of antimicrobials comprising seven classes were recorded in poultry farms while nine belonging to six classes in the small dairy farms. Majority of the farms (poultry, 87.7% and small scale dairy, 84.3%) used antimicrobials for therapeutic purposes. About 41% of the poultry and one third (34%) of the dairy farmers’ were not compliant to the drug withdrawal periods. Beta-lactams, fluoroquinolones, sulphonamides, tetracyclines and macrolides were the commonly used antimicrobials on these farms. In the poultry farms both those with records and those which relied on recall, antimicrobials were overdosed whereas in the small dairy farms, sulfadimidine, oxytetracycline and neomycin were within the appropriate dosing range (0.8–1.2). The majority (58.6%) of farmers had adequate level of practices (favorable) regarding antimicrobial use in cattle and poultry production. This was associated with the age and level of education of the cattle and poultry farmers. Conclusion The study revealed a widespread misuse of antimicrobials of different types and classes in both poultry and small-scale dairy farming in Dar es Salaam, Tanzania. This result gives insight into the antimicrobial use practices and its quantification. The information obtained can guide and promote prudent use of antimicrobials among the farmers by developing mitigate strategies that reduce antimicrobial resistance risk potentials.

Local and International Factors Affecting Participation of Tanzanian Small and Medium Enterprises in Market Opportunity Brought by the African Growth and Opportunity Act (AGOA)

The study aimed at assessing local and international factors that affect participation of Tanzanian Small and Medium enterprises in market opportunity brought by African Growth and Opportunity Act (AGOA). The study focussed on Tanzania local SMEs engaged in garments and textiles, handicrafts, leather goods, footwear and agro-processing subsectors. The study utilized mixed approach methods and involved a total of 129 respondents. Questionnaire and interview were the main tools for data collection. Information was collected from the owners and marketers of SMEs located in Dar es Salaam, the officials of Ministry of Industry and Trade as well as the Tanzania Ministry of foreign Affairs and East Africa Cooperation. Quantitative data was analysed using SPSS software and qualitative data was examined using MAXQDA software. Findings revealed that both local and international related factors were inhibiting Tanzanian SMEs from engaging in the AGOA market. Such factors have been narrated in this paper and recommendations have been given in order to increase engagement of Tanzanian SMEs in the AGOA market.

Learning Morality, Inequalities, and Faith

Christian and Muslim schools have become important target points in families and pupils' quests for new study opportunities and securing a 'good life' in Tanzania. These schools combine secular education with the moral (self-)formation of young people, triggering new realignments of the fields of education with interreligious co-existence and class formation in the country's urban centres. Hansjörg Dilger explores the emerging entanglements of faith, morality, and the educational market in Dar es Salaam, thereby shedding light on processes of religious institutionalisation and their individual and collective embodiment. By contextualising these dynamics through analysis of the politics of Christian-Muslim relations in postcolonial Tanzania, this book shows how the field of education has shaped the positions of these highly diverse religious communities in diverging ways. In doing so, Dilger suggests that students and teachers' religious experience and practice in faith-oriented schools are shaped by the search for socio-moral belonging as well as by the power relations and inequalities of an interconnected world.
