Uncertainties In Measuring Lifetimes Of Nuclear Excited States Using A Fast Electronic Timing System Made Of Nai (Tl) Scintillators, Innocent J Lugendo

Tanzania Journal of Science

Measurements of the lifetimes of nuclear excited states need to be as accurate as possible due to their crucial role in making or verifying various theoretical predictions in the nuclear science and astrophysics. Nevertheless, metrological difficulties in these measurements have brought about controversies that significantly influence the quest to understand the atomic structure, decay processes and nuclear reactions. Among the obstacles are the accuracy and precision of the systems and techniques used for measuring the lifetime of an excited state. It follows that any hypothesis regarding the nuclear behavior can only be considerable upon verification and accountability of stability and …

Antioxidant Potential Of Stingless Bee Honey From Mangrove And Montane Vegetation Types In Tanzania, Christopher Alphonce Mduda, Mkabwa Lawrence Katambo Manoko

Tanzania Journal of Science

Stingless bee honey is a rich source of antioxidants and is highly regarded in traditional medicine for the treatment of various ailments. The antioxidant capacity of honey can be influenced by its origin and the floral resources used by bees. Consequently, this study evaluated the antioxidant potential of stingless bee honey from two vegetation types: montane and mangrove. The honey samples displayed remarkable antioxidant potential, with notable levels of total phenolic content (197.0–263.1 mg GAE/100 g), total flavonoid content (118.5–156.7 mg QE/100 g), ascorbic acid (25.1–30.0 mg/100 g), lycopene (2.8–3.7 mg/100 g), β-carotene (0.8–1.7 mg/100 g), DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging activity …

This paper seeks primarily to explore the Indigenization of information shared and re-presented in the co-design exercises of designing on Country to contribute to the …

Development Of A Spray Pipe Evaporator For Application On Unproductive Salt Farm Land In Indonesia, Srie Muljani, Ketut Sumada, Alfian Rizki Pradana, Caecilia Pujiastuti

ASEAN Journal of Community Engagement

This article discusses the development of a prototype spray pipe evaporator and its efficiency in producing salt in Indonesia. Due to the length of the salt harvesting season in Indonesia, many salt farmers have closed their business doors, leaving many salt ponds abandoned. The spray pipe evaporator prototype was designed to produce a brine solution with a salinity of 23–24 Be from seawater, which has a salinity of 2.5–3.5 Be, in less than 3 days. This is faster than the conventional process of a brine solution salinity of 24 Be. The prototype spray pipe evaporator was assessed in a 20 …

Determining The De-Dieselisation Priorities Of Distributed Diesel Generators In An Electricity Company, Kresna Nurdianto, Ratih Dyah Kusumastuti

Journal of Environmental Science and Sustainable Development

The Indonesian Electricity Company (PLN) is one of the main players in the energy transition in Indonesia, and the company plans to achieve net zero emissions by 2060. One way to do this is by implementing the de-dieselisation program, i.e. reducing the use of diesel power plants (PLTD) with new energy and renewable power plants. The Indonesian electricity supply business plan (RUPTL) 2021-2030 targets the reduction of electricity supply from PLTD by 87% by 2030. The program requires a method to determine the order of priorities of PLTDs to be de-dieselised. This research uses multicriteria decision making, namely, analytical hierarchy …

Tanzania Journal of Science

This study examined the role of highly active antiretroviral therapy (HAART) in the dynamics of kidney diseases among HIV-infected individuals. A deterministic model was formulated for the dynamics of kidney disease in HIV-infected people with HAART as treatment in the model. Numerical simulations showed that though HAART reduces HIV progression to the AIDS stage, there is an increase in HIV-related kidney diseases. Also, the result obtained in this study showed that reducing the effective contact rate of HIV and improving the effectiveness of HAART by 99% in preventing the progression from HIV without symptoms group to HIV-related kidney diseases can …

Geochemical Characterization Of Hydrocarbon Source Rocks In The Jurassic – Cretaceous Ruvu Sub-Basin- Within The Coastal Basin Of Tanzania; Implications For Petroleum Prospecting., Hadija H Maumba, Charles H Kasanzu

Tanzania Journal of Science

In this study, we characterize hydrocarbon source rocks from the Ruvu sub-basin’s Kiwangwa well-1 using organic matter, total organic carbon (TOC), rock-eval pyrolysis and vitrinite reflectance data. Analytical results indicate fair to excellent TOC contents in the sub-basin, a feature suggesting conditions that favor organic matter production and preservation. Kerogen types II to IV are inferred for the Kiwangwa well-1 sediments. Using TOC vs S2 for the Early Jurassic and Triassic of Kiwangwa well -1 at depth intervals, good to very good source rocks are inferred. This suggests high generative organic matter suitable for hydrocarbon production. None generative organic matter …

Mathematical Analysis Of Monkeypox Transmission Dynamics With Control Strategie, Singo Juma Singo, Furaha Michael Chuma, Zubeda Seif Mussa

Tanzania Journal of Science

This study develops a mathematical model to analyze the transmission dynamics of Monkeypox and evaluate the effectiveness of control strategies. The model is formulated as a system of nonlinear differential equations, capturing key factors such as human-to-human transmission, zoonotic reservoirs, and control measures like vaccination, culling, personal hygiene and treatment. The model's equilibrium points, including the disease-free and endemic equilibria, are determined and analyzed for stability using the effective reproduction number, Re. Conditions under which Re<1 ensure the elimination of Monkeypox, while Re>1 indicates sustained transmission. A sensitivity analysis is performed to identify parameters that significantly influence Re​, such as the contact rate, effectiveness of control …

Few studies have been done in extreme environments including soda lakes such as Lake Natron which is found in Arusha region, Tanzania. This study recorded high pH and salinity values confirming the lake's extremity. Full-length 16S rRNA reads sequenced through PacBio was used to reveal first metagenomic snapshots of bacterial communities from 10 random points at the lake shoreline waters. The results showed the dominance of Proteobacteria and Firmicutes with relative abundances of 98.46% and …

A Bayesian Pharmacokinetics Integrated Phase I-Ii Design To Optimize Dose-Schedule Regimes, Mengyi Lu, Ying Yuan, Suyu Liu

Faculty, Staff and Student Publications

The schedule of administering a drug has profound impact on the toxicity and efficacy profiles of the drug through changing its pharmacokinetics (PK). PK is an innate and indispensable component of the dose-schedule optimization. Motivated by this, we propose a Bayesian PK integrated dose-schedule finding (PKIDS) design to identify the optimal dose-schedule regime by integrating PK, toxicity, and efficacy data. Based on the causal pathway that dose and schedule affect PK, which in turn affects efficacy and toxicity, we jointly model the three endpoints by first specifying a Bayesian hierarchical model for the marginal distribution of the longitudinal dose-concentration process. …

Rural Volunteer Emergency Personnel’S Perceptions Of Stressors During The Covid-19, Janette Lynn Nichols, Phd

Walden Dissertations and Doctoral Studies

Emergency personnel are expected to handle all situations without affecting their psyche. Distinct differences exist between urban and rural EMS personnel, with rural personnel frequently needing more organizational resources or support to manage stress. With the onset of COVID-19 in December 2019, rural emergency personnel were placed in exhaustive specific situations not experienced previously within the United States. This study was conducted to focus on how they internalize their stressors. This generic qualitative study aimed to determine the perceptions of stressors experienced by rural volunteer emergency personnel during the COVID-19 pandemic.
