Current State Of Seagrasses In Zanzibar: Impacts Of Coastal Economic Activities And Marine Protected Areas On Seagrass Cover, Danielle Purvis, Narriman Jiddawi

Capstone Collection

Seagrass meadows are located abundantly in Zanzibar, Tanzania and provide essential ecosystem services, such as sediment nutrient enrichment and blue carbon sequestration. However, seagrasses have been less researched or protected than other marine ecosystems. Although environmental variables affect seagrass health, evidence suggests that anthropogenic impacts are their greatest threats. The rapid expansion of seaweed farming and tourism and widespread use of harmful small-scale fishing practices in Zanzibar have contributed to the degradation and removal of seagrass meadows, disrupted coastal marine food chains, and reduced local biodiversity that seagrasses support. Public or private marine protected areas (MPAs) protect most of Zanzibar’s …

Barriers To Timely Disclosure Of Hiv Serostatus: A Qualitative Study At Care And Treatment Centers In Dar Es Salaam, Tanzania, Neelam Ismail, Nancy Matillya, Riaz Ratansi, Columba Mbekenga

Family Medicine, East Africa

Introduction: Disclosure of Human Immunodeficiency Virus (HIV) status is important to prevent the spread of HIV and maintain the health of people living with HIV, their spouses, and the community. Despite the benefits of disclosure, many people living with HIV delay disclosing their status to those close to them thereby increasing the risk for disease transmission. This study aimed to determine the barriers to timely disclosure of HIV serostatus for people living with HIV in Dar es Salaam, Tanzania, and identify what motivated disclosure.

Methods: A qualitative descriptive study using in-depth individual interviews was conducted with10 participants attending …

Smart Watch Detection Of Supraventricular Tachycardia (Svt): First Case From Tanzania, Nadeem Kassam, Omar Aziz, Eric Aghan, Samina Somji, Hanifa Mbithe, Mustaafa Bapumia, Robert Mvungi, Salim Surani

Internal Medicine, East Africa

Smartwatches like the Apple Watch have been on the rise worldwide and their use is gaining popularity in developing countries. Their ability to detect dysrhythmias is well documented. Present practice discourages the use of these devices as a diagnostic tool. Nevertheless, atypical findings from these devices should be clinically investigated. This case demonstrates an eventual diagnosis of supraventricular tachycardia (SVT) based on an Apple watch alert which was subsequently confirmed by electrophysiological evaluation.

Perceptions Of Surgeons On Surgical Antibiotic Prophylaxis Use At An Urban Tertiary Hospital In Tanzania, Elizabeth Mmari, Eunice Pallangyo, Authar Ali, Dereck A. Kaale, Isaac Mawalla, Muzdalfat Abeid

General Surgery, East Africa

Background: Surgical Site Infections are a major cause of morbidity and mortality among operated patients. In spite of the accessibility of universal and national guidelines for surgical prophylaxis, recent studies surveying the present routine of prophylaxis have demonstrated overutilization of a wide range antibacterial medication for a single patient. Few studies have shown qualitatively factors influencing this and perceptions of surgeons on surgical antibiotic prophylaxis use. Unfortunately, none of these studies have been done in Tanzania.

Objective: To describe the perceptions of surgeons on surgical antibiotic prophylaxis use at an urban tertiary hospital.

Methods: A qualitative study …

Rheological Properties Of Aged Crude Hard Wood Pyrolysis Oil, Divina D. Kaombe

Tanzania Journal of Engineering and Technology (TJET)

Upon storage of the pyrolysis oil, aging reactions may initiate phase separation and change of the rheological properties. These changes lead to unfavourable fuel characteristics in handling, transportation and applications. Efforts have been made for alleviation including methods on how to avoid these aging effects and development of equipment capable of handling aged pyrolysis liquids with unfavourable fuel characteristics. Therefore, the aim of this study was to explore the rheological properties of phase separated pyrolysis liquid fuel. Two batches of a well – stored poplar wood pyrolysis oils were used for the investigation; one batch was diluted with water to …

Prediction Of Uniaxial Compressive Strength Of Granite Rock Samples Of Lugoba Quarry Using Rebound Hammer Test, Moses Kongola, Karim Baruti

Tanzania Journal of Engineering and Technology (TJET)

Rebound hammer test is widely used as an indirect measure of uniaxial compressive strength for engineering materials such as concrete, soil, and rock in both civil and mining engineering works. In quarries, uniaxial compressive strength is a crucial parameter in the analysis of geotechnical problems involving rock stability and rock blasting design. This study aims at establishing the empirical models of uniaxial compressive strength fits on rebound hammer number that can be used to predict uniaxial compressive strength of granitic rock at Lugoba Quarry. Data for direct uniaxial compressive strength were obtained from uniaxial compressive strength test carried out on …

Prediction Of Four-Days Soaked California Bearing Ratio (Cbr) Values From Soil Index Properties, Pascal Ambrose, Siya P. Rimoy Dr

Tanzania Journal of Engineering and Technology (TJET)

California Bearing Ratio (CBR) laboratory testing is the conventional method for determining soaked strengths of pavement subgrades. The test requires careful preparation of soil samples followed by four days of water soaking before penetrating the samples using a standard plunger at prescribed rates to set depths. When the number of samples becomes large the determination of soaked CBR values becomes cumbersome as the test is laborious and time consuming. This study aimed at establishing an alternative way of determining soaked CBR by developing a model that would be used for estimating soaked CBR of fine- and coarse- grained soils without …

Socio-Technical Perspective For Electronic Tax Information System In Tanzania, Lucas Ngowi, Ellen Kalinga

Tanzania Journal of Engineering and Technology (TJET)

Socio-technical systems theory has rarely been used by system architects in setting up computing systems. However, the role of socio-technical concepts in computing, which is becoming social in nature, has made the concepts more relevant and commercial. Tax information systems are examples of such systems because they are influenced by external variables such as the political environment, technological trends, and social environment, introducing complexity in their deployment and determining the type of e-services and their delivery to a diverse group of people. It was observed that in Tanzania there is resistance, reluctance and minimal use of electronic tax system because …

Prospective Teacher Educators' Knowledge Development Through The Creation Of Multimedia Case Studies Of Practice, Crispin Ojwang

Dissertations - ALL

Despite the importance of teacher educators in influencing the quality of teacher education and by extension, the teacher quality, teacher educator preparation and professional development has received little attention from researchers and its pedagogical knowledge domain is often generalized from that of teachers. This study therefore explored the knowledge development of prospective teacher educators through creating multimedia case studies of practice. The study was based on the analysis of data collected previously through a teacher development experiment with eighteen prospective teacher educators during a two-semester course for doctoral students in several teacher education programs. I adopted Cochran-Smith and Lytle's theorizing …
