Realizar a modelagem de um aqüífero não é tarefa fácil. Em se tratando de um sistema aqüífero, a empreitada se torna ainda mais complexa. Neste trabalho, alguns dos parâmetros importantes para esse fim foram estimados a partir de simulações. Na região de estudo, existem poços tubulares que, em sua maioria, não foram perfurados somente na Formação Adamantina, mas também na Formação Serra Geral. Tal configuração conduziu à formulação de dois conjuntos de cenários a partir dos quais foi possível estimar valores de condutividade hidráulica para as duas formações. Com essa estimativa conseguiu-se também simular testes de bombeamento, seus respectivos cones de rebaixamento, bem como a interferência causada entre cones de rebaixamento. Com essa abordagem foi possível estimar o quanto um poço em funcionamento pode influenciar no nível estático de um vizinho. A contribuição da geofísica está no uso da eletroresistividade. Foram executadas 23 Sondagens Elétricas Verticais (SEV), das quais dezenove são SEV´s curtas (AB/2 500m) e quatro, longas (AB/2 1500), que forneceram informações sobre a espessura saturada do arenito e posição do topo do basalto, especialmente na região com poucos poços. Também foram realizados quatro Caminhamentos Elétricos (CE) no estudo de possíveis estruturas. Unindo os resultados da modelagem (simulação) e da geofísica, pôde-se relacionar os parâmetros hidrogeológicos e geoelétricos. Embora o conjunto de dados para a região não tenha sido o ideal, a metodologia se mostrou adequada e os resultados bastante razoáveis. Deste modo, foi possível a determinação de parâmetros hidrogeológicos em subsuperfície através de parâmetros geoelétricos medidos em superfície. / To perform the aquifer modelling is not an easy task. In the case of an aquifer system, the work becomes even more complex. In this work, some of important parameters for this purpose have been estimated from simulations. In the study area, there are wells that in most cases were not only drilled in Adamantina Formation but also in Serra Geral Formation. This configuration led to the formulation of two sets of scenarios from which it was possible to estimate values for hydraulic conductivity of these formations. With this estimate it could also simulate pumping tests, their cones of depression as well as the interference caused between cones of depression. With this approach it was possible to estimate how much a operating well can influence static level of a neighbour one. Geophysics contribution is in the use of electrical resistivity. Twenty-three Vertical Electrical Soundings (VES) were performed, nineteen of them are short (AB/2 500m), that provided information about the saturated thickness of sandstone as well as top of basalt, especially in the region with few wells, and four are long (AB/2 1500) VESs. Four electrical profiling (EP) were also carried out to study possible structures. Joining modelling (simulation) and geophysics results, it could be related hydrogeological and geoelectrical parameters. Although dataset for region was not the ideal, methodology was satisfactory, and results quite reasonable. Thus, it was possible to determine hydrogeological parameters in subsurface through measured geoelectrical parameters in surface.

This study is concerned with popular church music in Dar es Salaam and with changes in this music in relation to the concepts of temporality and spatiality. In part one, I argue that temporal change is experienced by human beings in relation to events or "stamps". Using selected stamps in the history of Tanzania from the 1980s to 2005, I discuss, on the one hand, how temporal events shaped various aspects of the music and people's experiences of the music and, on the other hand, how the music influenced people's experiences of various events and temporal rhythms. Various processes in the making ofpopular church music and various people involved in the creation of this music are considered to serve as stamps that mark the metamorphosis of the music. Likewise, the structural organization of the music and various musical elements imprint musical works and give them their identities thus causing them to be associated with other works that are organized in more or less similar ways. In part two, I use the theory of spatial trialectics to examine how popular church music is related to religious, national and gendered spaces. First, I discuss how the use of this music in religious spaces and the changes that have taken place in aspects of the music have been controversial, and I argue that the changes in the music led to changes in people's inner experiences of Christian spirituality. Second, I point out that the practice of African nationalism in this music has been aiming at liberating the national mental space through the use of traditional music materials and by addressing various national issues. The dynamics in this space involve the interaction between local and global music aesthetics. Third, I discuss the prominence ofwomen musicians in popular church music in recent years and the way in which this prominence has increased the focus on women's issues in the music. A close reading of selected songs reveals that individuals' experiences of gender problems are shaped by gendered mental space, which is informed by religious and other cultural norms. / Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2006.

The water and sewage company in Dar es Salaam, Tanzania has expressed a lack of integrated development plan for their service area. The current planning does not combine the social, economic and environmental stakeholders. This project investigated how rapid urbanisation and Tanzania’s vision of going from a low to middle-income country before 2025 will affect the water demand together with an investigation of the sustainability of the water supply in the city, Dar es Salaam. Furthermore, the study also investigated the collected historical data from the city’s biggest water supplier, Ruvu river, to examine if there are any changes in waterflow. The study used previous research, collaboration with students and interviews with the stakeholder and experts to collect information and estimate historical patterns. With the software, Water And Evaluation Planning (WEAP), the study processed the historical data to simulate future scenarios with aim on sustainability and development mentioned above. The study shows an increased demand in the future as a result of both urbanisation and economic growth and unmet demand in all scenarios. From the historical data the study shows a small decrease in total quantity and an upgoing trend of the peaks that occur during the biggest annual rainy season. Lastly, the study finds a need of looking at the current sources of supply to achieve sustainable utilization of the resource. / Det här projektet undersöker hur en snabb urbanisering och Tanzanias vision att gå från låg- till mellaninkomstland kan komma att påverka efterfrågan på färskvattnet i Dar es Salaam fram till 2030. Från historisk flödesdata från stadens största vattengivare, Ruvu floden undersöks om det går att utläsa några ändringar i flödena sedan 1980 fram till 2010. Fortsättningsvis diskuteras även hur ett hållbart nyttjande går att åstadkomma. Information och historisk data samlades från litteratursök, intervjuer och med samarbete med studenter och vatten- och sanitetsföretaget i staden. För att undersöka framtiden för stadens vattentillgång och efterfråga användes simulationsprogrammet Water And Evaluation Planning (WEAP) som genom att processerna historisk data, kan simulera liknande variationer i framtiden. Programmet gör det också möjligt för användaren att undersöka parallella scenarios med ändrade flöden och efterfråga. Studien visar att efterfrågan på vatten kommer att öka i alla scenarios och omött efterfrågan i alla scenarios. Studien finner att för hållbart nyttjande av denna resurs kräves mer undersökningar eller alternativ för att säkra tillgången på färskvattnet. De historiska data samlade från floden visar en liten nedåtgående trend i flödesmängd och en uppåtgående trend på mängd vatten som kommer under årets största regnperiod.​

This study examines the impact of a health education film, Chumo, in Dar es Salaam on knowledge about malaria in pregnancy. Specifically, the study examines the meanings that the selected audiences make after watching the film. Drawing on the tradition of ‘reception studies’, the data for this study was generated through focus group discussions. These discussions were preceded by thematic analysis of the film and its script. An analysis of the audiences’ responses reveals that Chumo, mostly, successfully conveyed new knowledge about malaria in pregnancy, and reinforced existing knowledge bases about the disease. The audiences were able to ‘decipher’ most of the preferred meanings (of the producers) with regard to the disease, particularly in relation to the transmission of the disease and its prevention in pregnant woman. For example, the analysis indicates that both women and men become more aware of the importance of attending antenatal care sessions at local clinics (hereafter ANC). An interesting finding is that men, mostly, expressed a reluctance to attend ANC with their wives because they fear having to undergo HIV/AIDS testing. Men also expressed the sentiment that attending ANC is a women’s responsibility. The discussion groups also raised issues about the use of insecticide-treated nets - some people believe that using them will affect their health because of the chemicals used to treat the nets. From the reception analysis, various other meanings and themes, relating to the choice of storylines and gender stereotypes used in the story, were raised in discussion. The study attempted to assess whether the storyline was advantageous in conveying the core educational messages, or if some elements of the storyline either ‘got in the way’ or reinforced gender roles in ways that may or may not be helpful in terms of combatting malaria in pregnancy. The study also found that Chumo stimulated interpersonal communication, which may trigger behaviour change. It can be demonstrated, at least for the participants in these focus groups, that the film motivated positive attitudes towards behaviour change, i.e. created at least some intention to change. However, interpersonal communication and attitude to change are not, of course, actual change of behaviour: these elements only indicate the possibility of behaviour change in the future. Further study needs to be undertaken to explore whether the actual change took place and whether the change is a result of the exposure to Chumo.

This study seeks to describe the factors contributing to high adolescent pregnancy rate in Kinondoni Municipality, Dar-es-Salaam. Through the study we get to know the social economic characteristics of adolescents, the adolescents' general knowledge of reproductive health issues and the source of this knowledge. The major discoveries made from this study are that the educational status and knowledge of reproductive health of these adolescents is low, some are already dropouts from school, and others were deprived of the chance to continue with secondary education. They have nothing tangible to do because of their low education and coupled with their low economic status, they are at risk of being involved in sexual activities at an early age, ending in pregnancies. In addition, their parents' educational and economic status was also found to be low. It is important then, parents, teachers and the community in general to arrest the rate of adolescent pregnancies. / HEALTH STUDIES / MA (HEALTH STUDIES)

Review

One of the main tasks for journalism is to provide people with the information they need to be able to make independent decisions that can help them improve their lives. In order to know that the media fullfils this task it is important to study how the information is received by the audience. This thesis aims to investigate if, and if so how, a selected group of people in Dar es Salaam use news media to inform themselves on problems regarding healthcare, and how they value the information on these topics.A minor field study was carried out in Dar es Salaam in April 2014. The study was limited to Dar es Salaam, the economic capital of Tanzania, because it holds the majority of the media. Three different residential areas were chosen for the study, these were Mwananyamala, which is a low-income area, Sinza, middle–income and Mikocheni, high–income. A survey questionnaire was distributed in each area, 30 in Mwananyamala, 31 in Sinza and 30 in Mikocheni, and in every area four interviews was preformed.According to the selection group there is plenty of healthcare information in the media that is useful to the audience but it is not seen to be very varied. Most information is about malaria and HIV/AIDS, which are two of the most common diseases in Tanzania, but many call for a broader reporting on health issues. Media is however a useful source of information, according to most of the respondents, and especially radio and television has a big impact since it reaches out to a large part of the population. This is a good thing as long as the information is factual and accurate, but several of the respondents believe that this is not always the case.

Mosquito-borne diseases like malaria, dengue fever, yellow fever and West Nile virus are serious problems in many parts of the world, especially in Africa, and partially in Ethiopia. Millions of people become infected and several hundred thousand people die worldwide from these diseases every year. The most conventional methods for mosquito vector control target female adult mosquitoes in a reactive way using insecticides. However, it is possible to perform proactive vector control through source reduction. The main focus of this study was to investigate if there are any associations between characteristics of managed still water bodies and the presence of mosquito larvae in Bahir Dar, Ethiopia. This was done by measuring twelve variables, both abiotic and biotic; pH, conductivity, dissolved oxygen, turbidity, biochemical oxygen demand, nitrate, phosphate, sulphate, carbonate, depth and presence of algae as well as collecting and counting mosquito larvae in ten different sites, during a time series of five weeks. The most common managed waters believed to serve as efficient breeding habitat for mosquitoes were ponds and ditches used for irrigation, drainage or cultivation. A total of 204 mosquito larvae were collected, where 95% were found in four of the ten sites, three of them were managed waters and the last one was unmanaged. Statistical analyses were performed in order to examine potential correlations and differences among the sites. Wilcoxon test was performed to investigate differences between managed and unmanaged waters. Simple linear regression analyses were performed to identify driving variables for the presence of mosquito larvae. The main results from the group tests were significant differences in mosquito larvae density between managed and unmanaged sites. Significant differences between mosquito sites and zero-sites for dissolved oxygen and sulphate were found. Simple linear regression revealed pH and dissolved oxygen as driving variables for mosquito larvae presence. It was concluded that resources should be put on treatment or manipulation of ponds, which were considered the preferred mosquito breeding habitats. However, if conflicts arise among interests concerning food production, measures must be planned and performed thoughtfully or focus should be put on less controversial breeding habitats. Among the driving variables, dissolved oxygen was the suggested variable to manipulate in order to reduce mosquito larvae populations. / Myggburna sjukdomar som malaria, denguefeber, gula febern och West Nile viruset orsakar allvarliga problem i många delar av världen, särskilt i Afrika, och till viss del Etiopien. Miljontals människor världen över blir smittade och flera hundratusen dör varje år till följd av dessa sjukdomar. De konventionella metoderna för att kontrollera och minska spridningen av myggburna sjukdomar handlar om att kontrollera vuxna myggor med insektsmedel. Det är dock möjligt att utföra en mer förebyggande vektorkontroll genom att minska populationen. Fokus för denna studie var att undersöka om det fanns några samband mellan mygglarvsförekomst och egenskaperna hos mänskligt reglerade eller oreglerade vatten i och kring Bahir Dar i Etiopien. Detta gjordes genom att mäta tolv variabler, både abiotiska och biotiska såsom; pH, konduktivitet, löst syre, turbiditet, biokemisk syreförbrukning, nitrat, fosfat, sulfat, karbonat, djup och algförekomst, samtidigt som mygglarver samlades in och räknades, vilket utfördes på tio olika platser under fem veckor. Den vanligaste typen av reglerade vatten som potentiellt skulle kunna utgöra effektiva mygglarvshabitat ansågs vara dammar och diken som används för bevattning, dränering eller odling. Totalt samlades 204 mygglarver in och 95 % av dem fanns i enbart fyra av de tio etablerade mätplatserna, där tre var reglerade och den sista var oreglerad. Statistiska analyser utfördes för att undersöka potentiella samband och skillnader i mygglarvsförekomst och uppmätta variabler bland de tio mätplatserna. Wilcoxons metod användes för att undersöka om det fanns skillnader mellan reglerade och oreglerade ytvattensamlingars larvförekomst och egenskaper. Enkel linjär regressionsanalys utfördes för att hitta eventuella drivvariabler som därmed anses styra mygglarvsförekomsten. De huvudsakliga resultaten i studien var att det förekom en signifikant skillnad i mygglarvsdensitet mellan reglerade och oreglerade ytvattensamlingar. Signifikanta skillnader i löst syre och sulfat förekom även mellan myggsiter och nollsiter. Enkel linjär regression visade på att pH och löst syre var de mest drivande variablerna för mygglarvsförekomsten i denna studie. Slutsatsen var att dammar utgjorde de mest tilltalande habitaten i samband med mygghonors äggläggning och därför borde prioriteras med avseende på resursfördelning vid planering och utförande av vektorkontroll. Om det skulle uppstå konflikter mellan olika intressen som kan äventyra matproduktionen bör insatser planeras och genomföras med försiktighet eller istället göras i andra mindre kontroversiella mygglarvshabitat. Den drivvariabel som ansågs vara den mest lämpliga att manipulera var löst syre.
