Tanzania Journal of Engineering and Technology (TJET)

The area north of the Dar es Salaam City is endowed with beautiful sandy beaches and high concentration or tourist beach hotels that are threatened by coastal erosion. In order to protect the buildings and land, coastal erosion must be controlled by mitigation options that are based on scientific data, wave and current climate along the East African region are generally controlled by the seasonal monsoon winds. During the north-east monsoon period when Winds blow from the Northeast, the wind-generated waves approach the coast from the northerly direction and produce long-shore Currents With a southerly component. During the southerly monsoon …

Efeci's In Reinforced Concrete Due To Environmental Conditions, And Concrete Treatment: A Case Study At The University Of Dar Es Salaam, I Rubaratuka

Tanzania Journal of Engineering and Technology (TJET)

Concrete is produced by mixing together cement, water and aggregates (i. e. sand and coarse aggregates) in specified proportions, It can do well with compressive forces but it is very weak under tensile forces. TO Overcome this problem, steel reinforcement are normally added to produce reinforced concrete which can also withstand tensile forces Experience shows that environmental conditions may have a negative impact On the durability of reinforced concrete structures resulting in development of defects if not properly assessed and appropriate measures adopted to arrest the same at the design and construction stages.

Mapping 'New' Geographies Of Religion: Politics And Poetics In Modernity, Lily Kong

Research Collection School of Social Sciences

This article reviews geographical research on religion in the 1990s, and highlights work from neighbouring disciplines where relevant. Contrary to views that the field is incoherent, I suggest that much of the literature pays attention to several key themes, particularly, the politics and poetics of religious place, identity and community. I illustrate the key issues, arguments and conceptualizations in these areas, and suggest various ways forward. These 'new' geographies emphasize different sites of religious practice beyond the 'officially sacred'; different sensuous sacred geographies; different religions in different historical and place-specific contexts; different geographical scales of analysis; different constitutions of population …

No Easy Walk: Advancing Refugee Protection In South Africa, Jeff Handmaker

Southern African Migration Programme

South Africa only began accepting individual applications for political asylum in 1994. A policy designed to recognize former Mozambican refugees for the purposes of a repatriation program became the (awkward) basis of the asylum procedure up until April 2000. Criticized by some, a lively discussion raising often-contradictory views began in 1996, leading to a policy reform process culminating in the Refugees Act in December 1998. The Act only came into force at the beginning of April 2000. This article analyzes the process of policy development in South Africa, focusing on practical and theoretical challenges facing the government in the implementation …

Incidence Of Symptomatic And Asymptomatic Plasmodium Falciparum Infection Following Curative Therapy In Adult Residents Of Northern Ghana, S. Owusu-Agyei, K. A. Koram, J. Kevin Baird, G. C. Utz, F. N. Binka, F. K. Nkrumah, D. J. Fryauff, S. L. Hoffman

United States Public Health Resources

Adult residents of holoendemic malaria regions in Africa have a naturally acquired immunity (NAI) to malaria that renders them more resistant to new infections, limits parasitemia, and reduces the frequency and severity of illness. Given such attributes, it is not clear how one might evaluate drug or vaccine efficacy in adults without serious confounding. To determine symptomatic and asymptomatic malaria attack rates in adults of northern Ghana, 197 men and women underwent curative therapy for any pre-existing malaria infections at the start of the high transmission (wet) season. They were monitored for first parasitemia and first clinical episode of infection …

Interventions To Reduce Hiv/Aids Stigma: What Have We Learned?, Lisanne Brown, Lea Trujillo, Kate Macintyre

HIV and AIDS

Stigma is a common human reaction to disease. Throughout history many diseases have carried considerable stigma, including leprosy, tuberculosis, cancer, mental illness, and many sexually transmitted diseases. HIV/AIDS is only the latest disease to be stigmatized. This paper reviews 21 interventions that have explicitly attempted to decrease AIDS stigma both in the developed and developing countries and 9 studies that aim to decrease stigma related with other diseases. The studies selected met stringent evaluation criteria in order to draw common lessons for future development of interventions to combat stigma. This paper assesses published and reported studies through comparison of audiences, …

Hiv And Partner Violence: Implications For Hiv Voluntary Counseling And Testing, Horizons Program

HIV and AIDS

An important component of HIV voluntary counseling and testing (VCT) programs is encouraging clients to inform partners of their serostatus, yet many clients do not do so. Studies have found that a serious barrier to disclosure for women is fear of a violent reaction by male partners and that HIV-infected women are at increased risk for partner violence. Building on previous research, this study explored the links between HIV infection, serostatus disclosure, and partner violence among women attending the Muhimbili Health Information Center (MHIC), a VCT clinic in Dar es Salaam, Tanzania. As noted in this summary, the study first …

Hiv And Partner Violence: What Are The Implications For Voluntary Counseling And Testing?, Carolyn Knapp

HIV and AIDS

Millions of women around the world face two great threats to their health and well-being: HIV/AIDS and violence by an intimate partner. One of the strongest associations between the two is the role that violence and the threat of violence play in limiting a woman’s ability to negotiate safer sex with a partner. A similar fear of violence also discourages women who receive HIV voluntary counseling and testing (VCT) from telling partners about test results. This study explored the links between HIV infection, serostatus disclosure, and partner violence among women attending a VCT clinic in Dar es Salaam, Tanzania. Researchers …

Hiv And Partner Violence: Implications For Hiv Voluntary Counseling And Testing Programs In Dar Es Salaam, Tanzania, Suzanne Maman, Jessie K. Mbwambo, Margaret Hogan, Gad P. Kilonzo, Michael D. Sweat, Ellen Weiss

HIV and AIDS

This study explored the links between HIV infection, serostatus disclosure, and partner violence among women attending a VCT clinic in Dar es Salaam, Tanzania. Men and women both perceive HIV testing as a way to plan for the future but are motivated to undergo testing by a number of different individual, relationship, and environmental factors. The women in our study described more barriers to HIV testing than did men, and women who have communicated with their partners about VCT before seeking services are significantly more likely to share their HIV test results than those who have not talked with their …

An Analysis Of Anemia And Child Mortality, B.J. Brabin, Zul Premji, F. Verhoeff

Pathology, East Africa

The relationship of anemia as a risk factor for child mortality was analyzed by using cross-sectional, longitudinal and case-control studies, and randomized trials. Five methods of estimation were adopted: 1) the proportion of child deaths attributable to anemia; 2) the proportion of anemic children who die in hospital studies; 3) the population-attributable risk of child mortality due to anemia; 4) survival analyses of mortality in anemic children; and 5) cause-specific anemia-related child mortality. Most of the data available were hospital based. For children aged 0-5 y the percentage of deaths due to anemia was comparable for reports from highly malarious …

Islam, Indigenous Traditions, And Adventism In Kenya: A Comparative Study To Determine Effective Approaches To Evangelize Kenyan Muslims, Joseph Kilonzo

Doctor of Ministry Projects

Problem

Islam is spreading speedily in Kenya from the coast and the north towards inland areas, converting great number of persons and communities. The Islamic influence is evident in almost all spheres of life in the country, including social, political, economical, and spiritual. Muslims are particularly hard to reach with the gospel. However, this does not mean the task of reaching them is unsurmountable. The task of this project, therefore, was to provide a biblical, theological, and missiological strategy for presenting the gospel to Muslims in Kenya with the view of winning them over to Christianity (Adventism).

Method

Analysis Of Hydrocarbon Materials By Use Of Nonpolar Matrices In Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry (Maldi-Ms)., Stephen Francis Macha

LSU Historical Dissertations and Theses

In this study, polyaromatic hydrocarbon compounds including anthracene, pyrene, acenaphthene and perylene were investigated as nonpolar matrices in matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the analysis of selected nonpolar analytes. First, the influence of matrix and the analyte ionization potentials on a charge-transfer ionization mechanism were determined. Results of these studies demonstrated that formation of radical molecular cations in MALDI-MS depends on the ionization energy difference between the matrix and the analyte. Charge-transfer ionization occurs only when the ionization potential of the matrix is higher than that of the analyte. Next, nonpolar matrices were investigated for the analysis of …

Taking Globalization Seriously: Towards General Jurisprudence (Book Review Of Globalization And Legal Theory By William Twining), Doron M. Kalir

Law Faculty Articles and Essays

Part II provides an account of the jurisprudence of Globalization and Legal Theory. Due to the novelty of many of the issues discussed in the book, as well as their importance to the understanding of Twining's recommendations, I have provided a longer than usual account of several chapters. Part II touches upon one of the central jurisprudential dichotomies introduced by Twining—the distinction between general and particular jurisprudence. Twining compares different accounts of the distinction using pairs of canonical jurists. In particular, he compares H.L.A Hart's Postscript with Dworkin's Law's Empire. In this part, I juxtapose Twining's record of this …

Liberalization And Politics Of Environmental Management In Tanzania, Alicia Bosensera Magabe

LLM Theses and Essays

This thesis examines the factors that have prevented the development of an environmental protection legal and institutional regime in Tanzania. It argues that the central focus of economic reforms has been to kick-start the economy by increasing growth through the maximization of resource exploitation. As a result, concerns for environmental sustainability have been relegated to the periphery of the development agenda. Secondly, as a result of domestic resource scarcity brought on by the economic crisis, environmental policymaking has been held hostage to the influence of foreign donors whose agendas have often been at cross-purpose to environmental protection. Thirdly, the nature …

Acute Haemolysis In Childhood Falciparum Malaria, H. Ekvall, P. Arese, F. Turrini, K. Ayi, F. Mannu, Zul Premji, A. Bjorkman

Pathology, East Africa

Acute haemolysis associated with clinical episodes of high-level Plasmodium falciparum parasitaemia was studied in 20 children from an holoendemic area (coastal Tanzania). The change in blood haemoglobin (Hb) concentration ranged from -46 to +5 g/L during the 72-h observation period and was linearly related to maximum parasitaemia. Balance studies between loss of blood Hb, increase in plasma Hb and appearance of Hb in the urine indicated that extravascular clearance of red cells was the predominant mode of erythrocyte clearance. Most subjects, however, showed minor signs of intravascular haemolysis. The plasma Hb was ≪1% of blood Hb and haemoglobinuria was detected …

Hemoglobin Concentration In Children In A Malaria Holoendemic Area Is Determined By Cumulated Plasmodium Falciparum Parasite Densities, H. Ekvall, Zul Premji, S. Bennett, A. Bjorkman

Pathology, East Africa

In malaria holoendemic areas children are anemic, but the exact influence of falciparum malaria on hemoglobin (Hb) concentration remains largely unsettled. Prospective data were therefore collected in children < 24 months of age during five months in a Tanzanian village. Children with mean asymptomatic parasitemia ≥ 400/μl had lower median Hb levels during the study than those with mean density < 400/μl. The difference was 9.7 g/L (95% confidence interval [CI] 2.8-17). In children with one or more clinical malaria episodes, the median Hb was 8.3 g/L (95% CI 0.9-16) lower than those without episode. If early treatment failure was recorded, the immediate effect on Hb was particularly important with a mean drop of 17 g/L. Interestingly, at study-end the Hb concentration represented a function of the area under the parasitemia curve (AUPC) during the previous five months, adjusting for age. In conclusion, stepwise deterioration in median Hb levels was found by asymptomatic parasitemia, clinical malaria episode, and most significantly, treatment failure.
