Effects Of Perpetrator Types And Gender-Based Violence On Condom Use Among Tanzanian Female Sex Workers, Lashonda Hall

Walden Dissertations and Doctoral Studies

HIV status among female sex workers (FSWs) continues to be a significant public health concern. Condom use is associated with HIV cases among FSWs. Gender-based violence (GBV) plays a role in FSWs HIV status. While studies have investigated the relationship between GBV and condom use, little is known about the impact of factors such as perpetrator type and substance use. I aimed to examine whether perpetrator type and substance use affect the relationship between GBV and condom use among FSWs in Tanzania. Secondary data analysis was performed on 1,502 FSWs extracted from the 2020 Tanzanian, John Hopkins Program for International …

Severe Crohn’S Disease With Intra-Abdominal Fistula: First Reported Case From Tanzania, Nadeem Kassam, Omar Aziz, Eric Aghan, Melchisedeck Mandwa, Caroline Ngimba, Hanifa Mbithe, Salim Surani, Casmir Wambura

Internal Medicine, East Africa

We describe a case of Crohn's disease occurring in a young Tanzanian female. Crohn’s disease is rare in Africa and not encountered normally. The presentation of Crohn’s disease overlaps with many other abdominal disorders that are common in an African setting, such as tuberculosis and schistosomiasis. The disease is probably underdiagnosed in Africa due to limitations in diagnostic testing and rarity.

Obstetrics and Gynaecology, East Africa

Background: ST-segment changes to the fetal electrocardiogram (ECG) may indicate fetal acidosis. No large-scale characterization of ECG morphology immediately after birth has been performed, but ECG is used for heart rate (HR) assessment. We aimed to investigate ECG morphology immediately after birth in asphyxiated infants, using one-lead dry-electrode ECG developed for HR measurement.

Methods: Observational study in Tanzania, between 2013-2018. Near-term and term infants that received bag-mask ventilation (BMV), and healthy controls, were monitored with one-lead dry-electrode ECG with a non-diagnostic bandwidth. ECGs were classified as normal, with ST-elevations or other ST-segment abnormalities including a biphasic ST-segment. We analyzed ECG …

A Language For The World: The Standardization Of Swahili, Morgan J. Robinson

Ohio University Press Open Access Books

This intellectual history of Standard Swahili explores the long-term, intertwined processes of standard making and community creation in the historical, political, and cultural contexts of East Africa and beyond.

Morgan J. Robinson argues that the portability of Standard Swahili has contributed to its wide use not only across the African continent but also around the globe. The book pivots on the question of whether standardized versions of African languages have empowered or oppressed. It is inevitable that the selection and promotion of one version of a language as standard—a move typically associated with missionaries and colonial regimes—negatively affected those …

Food Security Through Disaster Planning In Tanzania: How Agriculture-Based Disaster Preparedness Can Improve Food Security In Tanzania, Savannah A. Emerich

Masters Theses

In Tanzania, half the population lives below the poverty line and suffers from food insecurity. Of the population, women and children primarily suffer from malnutrition due to food insecurity. For Tanzania, the problem is so severe that some women do not name their newborns for weeks or months due to their unlikely survival. This problem worsens for those who have a significant reliance on agriculture and live in the nation’s rural areas. These rural communities face more traumatic burdens when floods and droughts destroy crops, fields, and tools and ruin livelihoods. A solution has not been implemented thus far due …

Rural Electrification Using Iliceto Shield Wire Scheme In Developing Countries: Tanzania Case Study, Heavenlight M Munisi, Santos Kihwele

Tanzania Journal of Science

Rural electrification rate in Tanzania is still very low despite the efforts made by the Rural Energy Agency (REA) in Tanzania. Rural electrification using medium voltage (MV) method has two major obstacles. First obstacle is high cost associated with the cost of extending the grid electricity to rural areas. Second obstacle is remoteness of the villages, which leads to high power loss during transmission. In lieu of economic extension of rural electrification areas, this paper proposes a low cost solution of Iliceto Shield Wire Scheme (ISWS). This technique involves insulating shield wires (SW) from high voltage (132-400 kV) transmission line …

Determination Of Cramer-Rao Lower Bound (Crlb) And Minimum Variance Unbiased Estimator Of A Dc Signal In Awgn Using Laplace Transform, Abdi T. Abdalla

Tanzania Journal of Science

This paper presents an alternative approach for the determination of Cramer-Rao Lower Bound (CRLB) and Minimum Variance Unbiased Estimator (MVUE) using Laplace transformation. In this work, a DC signal in Additive White Gaussian Noise (AWGN) was considered. During the investigation, a number of experiments were conducted to analyze different possible outputs under different conditions, and then the patterns of the outcomes were studied. Finally closed-form expressions for the CRLB and MVUE were deduced employing the Laplace transformation. The resulting expressions showed that the proposed method has almost the same number of steps as the existing method. However, the latter requires …

The increase in the corrosion rate with increasing temperature was observed for both uninhibited and inhibited systems. Addition of halide ions to the Acacia senegal gum exudate solution enhanced the corrosion inhibition efficiency because of synergistic effects, …

Physico-Chemical Properties Of Mechanically Extracted Banana Juice At Different Ripening Stages, Mathayo G Mathias, Lilian D Kaale, Oscar Kibazohi

Tanzania Journal of Science

This paper presents the findings of a study on physico-chemical properties of low viscosity banana juice from five banana cultivars: Pisang Awak (PSA) an ABB genome, Yangambi km5 (YKM5) an AAA genome and cultivars from AAA-EA genome, namely Mbilabile, Ndeshi and Mlonga. Low viscosity banana juice was extracted using improved mechanical method at five ripening stages. The physico-chemical properties significantly varied according to cultivars and ripening stages (p < 0.05). Yields, total soluble solids (TSS), titratable acidity (TA) and pH were in the range of 19.50–74.03%, 7.33–27.64 ºBrix, 0.37–0.76% malic acid equivalent and 4.09–4.70, respectively. Yields decreased in the order of Mbilabile > Ndeshi > Mlonga > YKM5 > PSA whereas the total soluble solids increased as follows Mlonga < Mbilabile < Ndeshi < YKM5 < PSA. Furthermore, ashes and mineral contents decreased with ripening stages whereas the low viscosity banana juice was rich in potassium and magnesium. Finally, the study recommends stage 5 of the ripeness as ideal for producing low viscosity banana juice. Keywords: Mechanical extraction, Banana cultivar, Ripening stage, Tannin, Banana juice.
