The Role Of Zinc Precursor Concentration In Modulating The Structural, Optical, And Electrical Properties Of Sol-Gel Derived Czts Thin Films, Justine John Tibaijuka Jun 2026

The Role Of Zinc Precursor Concentration In Modulating The Structural, Optical, And Electrical Properties Of Sol-Gel Derived Czts Thin Films, Justine John Tibaijuka

Tanzania Journal of Science

This study reports on CZTS thin films fabricated by sol–gel spin coating using zinc acetate dihydrate, copper acetate dihydrate, tin chloride, and thiourea dissolved in methanol with monoethylamine as a stabilizer. The films were annealed rapidly at 540 °C by using an RTP furnace. Results show the significant influence of zinc concentration on films’ properties with band gap evolution between 1.46 and 1.7 eV, along with high absorption coefficients exceeding 10⁴ cm⁻¹ in the visible range. Structurally, the films evolved from poorly crystalline at low Zn content to well- crystallized, (112)-oriented kesterite near stoichiometry. However, excessive Zn caused slight degradation …

Linear Programming Model For Optimal Crop Allocation Under Varying Land Sizes In Pawaga, Tanzania, Mustapha Abbas Kiswanya, Seleman Ismail, Saul Mpeshe Jun 2026

Linear Programming Model For Optimal Crop Allocation Under Varying Land Sizes In Pawaga, Tanzania, Mustapha Abbas Kiswanya, Seleman Ismail, Saul Mpeshe

Tanzania Journal of Science

Farmers often rely on intuition when selecting crops, which can lead to suboptimal profits. In this study, we examine the optimal annual crop allocation under varying land sizes for farmers in Pawaga, Iringa District, Tanzania. A parametric linear programming (LP) model is developed to determine crop allocation combinations that maximise profit subject to land, labour, and capital constraints. Unlike conventional approaches that require separate models for different farm sizes, the proposed model accommodates land holdings ranging from 1 to 9 acres and integrates nine crop types within a single framework. Data were collected over three (3) agricultural seasons from extension …


Joint Channel And Phase Noise Estimation For Mmwave Ofdm Systems Using Adaptive Kalman Filtering, Kwame Salum Ibwe Jun 2026

Joint Channel And Phase Noise Estimation For Mmwave Ofdm Systems Using Adaptive Kalman Filtering, Kwame Salum Ibwe

Tanzania Journal of Science

This manuscript presents a joint channel and phase-noise estimation framework for millimeter-wave (mmWave) OFDM systems based on an adaptive extended Kalman filter (EKF). The proposed method formulates a unified state-space model that simultaneously tracks time-varying multipath channels and oscillator phase noise, a critical impairment in 5G NR frequency range 2 (FR2) and emerging 6G transceivers. An innovation-based covariance adaptation mechanism is introduced to enhance estimation accuracy while maintaining computational efficiency. Simulation results demonstrate that the proposed approach achieves up to a 5 dB SNR gain at a target BER of 10⁻³, maintains NMSE below 10⁻³ for linewidths up to 200 …

This study evaluated the effects of plant leaf meals (PLMs) on haematological parameters in Nile tilapia (Oreochromis niloticus). The PLMs of cassava, sweet potatoes, cowpeas and common beans were substituted at the rate of 100% (mixed leaves of all four species, Diet 5), followed by each separate leaf meal at 100% (Diet 4), 75% (Diet 3), 50% (Diet 2) and 0% (control diet containing fish meal, Diet 1). Fish collected from Mbegani Fisheries Institute were kept in five, 80 …


From Tragedy To Liberation: The Tragic Mulatta And Abolition Democracy At The Intersection Of Race And Gender In The Quadroons And The Octoroon, Maram Mohammed Mahmoud Samman Jun 2026

From Tragedy To Liberation: The Tragic Mulatta And Abolition Democracy At The Intersection Of Race And Gender In The Quadroons And The Octoroon, Maram Mohammed Mahmoud Samman

University of Tabuk Journal for Humanities and Social Sciences

This essay explores the figure of the tragic mulatta in Lydia Maria Child’s The Quadroons and Dion Boucicault’s The Octoroon, analyzing how mixed-race female characters critique the racial and gender hierarchies of 19th-century America. Using an intersectional lens, it examines how race, gender, and class shape the identities and tragic fates of Xarifa and Zoe—women who were socially excluded from both Black and White communities. Drawing on W.E.B. Du Bois’s concept of double consciousness and the framework of Abolition Democracy, the essay argues that the tragic mulatta is not merely a narrative trope but a site of political tension and …

Modelling Of Dust Devil Flow Dynamics: Effects Of The Sharpness Parameter On Velocity And Pressure, Deepanshu Kumar, Hossein Jafari Jun 2026

Modelling Of Dust Devil Flow Dynamics: Effects Of The Sharpness Parameter On Velocity And Pressure, Deepanshu Kumar, Hossein Jafari

Mathematical Modelling and Numerical Simulation with Applications

This work discusses the development of a straightforward model of dust devils, demonstrating a method for estimating wind speed and pressure. The current model incorporates momentum equations and the mass conservation equation for steady, axisymmetric, inviscid, and incompressible flow. In this model, the radial velocity is first considered, which is restricted in both the radial and axial directions. The sharpness parameter is also incorporated into the radial velocity formulation, as described by Vatistas model. Using the radial velocity as a foundation, we derive the azimuthal and axial velocities. The study further evaluates the pressure. Notably, for large values of the …


Dynamical Behavior, Extinction And Persistence In A Stochastic Delayed Two-Strain Epidemic Model With A Generalized Crowley-Martin Incidence Rate, Amina Allali, Dounia Bentaleb, Saida Amine Jun 2026

Dynamical Behavior, Extinction And Persistence In A Stochastic Delayed Two-Strain Epidemic Model With A Generalized Crowley-Martin Incidence Rate, Amina Allali, Dounia Bentaleb, Saida Amine

Mathematical Modelling and Numerical Simulation with Applications

This paper develops and analyzes a novel delayed stochastic SIR epidemic model with two interacting strains and general incidence functions. By establishing the existence and uniqueness of a positive global solution, the well-posedness of the model under stochastic perturbations is ensured. Extinction occurs when the stochastic reproduction number falls below unity, as demonstrated through Itô calculus and martingale convergence theorems, while persistence is guaranteed under the Crowley–Martin incidence when it exceeds one. Numerical experiments based on the Positive Preserving Truncated Euler–Maruyama (PPTEM) scheme confirm the analytical predictions and highlight the influence of time delay and noise intensity on the long-term …


Entrenchment And Expansion: How Political Dynasties Affect Poverty Within And Between Philippine Provinces, Jurel K. Yap Jun 2026

Entrenchment And Expansion: How Political Dynasties Affect Poverty Within And Between Philippine Provinces, Jurel K. Yap

Asia-Pacific Social Science Review

The persistence of poverty in the Philippines is linked in the literature to the prevalence of political dynasties, yet the precise mechanisms of this relationship remain underexplored. This study sought to disentangle two distinct phenomena: the effect of long-term dynastic entrenchment (structural, between-province differences) from that of dynamic dynastic expansion (changes within a province over time). To do so, this paper employed a within-between panel data model on a unique dataset covering 80 provinces from 2004 to 2021, with the Political Concentration Index (Political HHI) as the primary measure of dynastic power. The results showed that while dynastic entrenchment and …


A Case Study Of Sport And Racism In Australia: A Qualitative Document Analysis, Vegneskumar Maniam, Kristy O’Neill Jun 2026

A Case Study Of Sport And Racism In Australia: A Qualitative Document Analysis, Vegneskumar Maniam, Kristy O’Neill

Asia-Pacific Social Science Review

Australia is well known as a ‘sporting nation’ with outstanding elite sporting achievements and grassroots-level sports participation. The reality for Australia’s First Nations people and those from Culturally and Linguistically Diverse (CALD) backgrounds, however, tends to differ from the mainstream Australian population. One of the contributing factors being argued within this paper is the prevalence of historical and contemporary racism in Australian sport. This study focuses on four of Australia’s most popular community-participation sports, including Australian Rules Football (ARF), Cricket, Netball, and Swimming. Using a Qualitative Document Analysis method, this research investigates both primary and secondary sources for instances of …


Institutionalizing Public Consultation In Thai Health Legislation: Lessons From Ria And Pls Practices, Stithorn Thananithichot, Wichuda Satidporn, Chompunoot Tangthavorn Jun 2026

Institutionalizing Public Consultation In Thai Health Legislation: Lessons From Ria And Pls Practices, Stithorn Thananithichot, Wichuda Satidporn, Chompunoot Tangthavorn

Asia-Pacific Social Science Review

Public consultation is increasingly recognized as a cornerstone of democratic governance, yet its institutionalization in middle-income democracies such as Thailand remains uneven. Although the 2017 Constitution and the 2019 Act on Legislative Drafting and Legal Evaluation mandate participatory processes through Regulatory Impact Assessment (RIA) and Post-Legislative Scrutiny (PLS), implementation has often remained procedural rather than substantive. This study examines how consultation practices operate within Thailand’s public health legislation, a policy domain characterized by significant distributive and ethical implications. Using a qualitative comparative case study design, the research analyzes three legislative processes: the National Health Security Act B.E. 2545 (2002), the …

Cultural Heritage Management In Thailand: The Perspective From Regulation, Implementation, And Impediment Under Public-Private Partnership And Civil Society Participation, Ratchaphon Amsuk

Asia-Pacific Social Science Review

Following the new public management concept, public-private partnership has been instituted in the realm of public administration, transitioning the emphasis from primarily the public sector as the principal actor to encompass the private sector’s role in delivering public services. To enhance service inclusion, civil society has been incorporated as an additional social element to bolster public administration. This study aims to elucidate cultural heritage management in Thailand, focusing on regulations and action, including impediments through the public-private partnerships concept and the civil society concept. The qualitative approach included in-depth interviews and focus groups for data collection. The research revealed the …

Natural Radioactivity And Radiological Hazards In Sediments From The Lindi Coast, Indian Ocean, Tanzania, Viator Mujuni, Innocent J. Lugendo

Tanzania Journal of Science

The Lindi coast of the Indian Ocean, located in southeastern Tanzania, supports rich biodiversity and has recently experienced rapid growth in socio-economic activities such as fishing, mining, and oil and gas exploration. These activities may enhance levels of natural radioactivity in coastal sediments, potentially increasing radiation exposure to local populations. Therefore, monitoring radioactivity levels and estimating associated radiation doses in this region is important. In this study, thirty-six sediment samples were collected from twelve locations along the Lindi coast and analysed for naturally occurring radionuclides using high-purity germanium (HPGe) gamma-ray spectrometry. The activity concentrations of 226Ra, 232Th, and …

Concealed History Of Microplastic Pollution In The Msimbazi Estuary, Dar Es Salaam, Tanzania, Dativa J. Shilla

Tanzania Journal of Science

This study reconstructed the historical deposition of microplastics in sediments of the Msimbazi Estuary, Tanzania, using a radiometrically dated sediment core. Sediment chronology established using ²¹⁰Pb and the Constant Initial Concentration (CIC) model provided an approximately 83-year depositional record. The ²¹⁰Pb age model suggested marked temporal variability in sedimentation rates, with peaks around 1961, 1998, 2013, and 2015, potentially reflecting hydrological extremes and catchment disturbances. Anthropogenic microparticles were detected throughout most of the sediment core, with concentrations ranging from below detection limit (BDL) to 34 items kg⁻¹ dry weight (mean 8.5 ± 3.2 items kg⁻¹), and their abundance generally increased …


Associations Between Self And Peer's Fear Of Fat In Predicting Dietary Restraint, Weight/Shape/Eating Concerns, And Thin-Ideal Internalization: A Dyadic Exploration In Female Friend Pairs, Sm O'Connor, Cg Martin, Leora L Haller, S Marhan Jun 2026

Associations Between Self And Peer's Fear Of Fat In Predicting Dietary Restraint, Weight/Shape/Eating Concerns, And Thin-Ideal Internalization: A Dyadic Exploration In Female Friend Pairs, Sm O'Connor, Cg Martin, Leora L Haller, S Marhan

Department of Psychology Faculty Scholarship and Creative Works

Objective Fear of fat may reflect concern regarding rejection one may experience at a higher weight. Peers play a major role in socialization and support during adolescence and young adulthood. While studies have highlighted peers as an important source of influence underlying disordered eating, it is unclear whether one's own fear of fat or peers' fear of fat is associated with concerns about weight, shape, eating, and eating behaviors.Method The present study used data from 94 female friend pairs (mean age = 20.18, SD = 1.77). Actor-partner interdependence models were conducted to explore the extent to which one's own fear …

Tanzanian Economic Review

COVID-19 challenged mobility, redefining crisis navigation and resilience. A modified Challenge Metamorphosis Model (CMM) is proposed to understand crisis navigating process in tourism business resilience-building. A pragmatic mixed-method design, involving 158 tourism-business respondents, multiple regions, interviews, and observation during June–November 2020, was applied. Impacts, challenges, opportunities, varied business responses and outcomes were mirrored. Immediate reactive closure and booking cancellation responses were distinguished from proactive adaptive business continuity measures with low visitors, postponement, few bookings and negotiable employment flexibility. Health, safety, and culturally embedded coping practices and their reinvention aided crisis navigation. Medium-term crisis navigating strategies were differentiated from long-term resilience-building …


Relative Effectiveness Of Exchange Rate Targeting, Monetary Targeting And Inflation Targeting Frameworks In Sub-Saharan Africa, Joyce Gervas Jun 2026

Relative Effectiveness Of Exchange Rate Targeting, Monetary Targeting And Inflation Targeting Frameworks In Sub-Saharan Africa, Joyce Gervas

Tanzanian Economic Review

In recent years, many central banks around the world have shifted from frameworks such as monetary targeting and exchange rate targeting to inflation targeting to achieve price stability and enhance central bank credibility. The same pattern has been observed in Sub-Saharan Africa (SSA), where the number of inflation-targeting countries has increased from 1 in 2000 to 5 in 2022, as countries continue to exit other frameworks, especially the monetary targeting regime. However, there is an ongoing debate in SSA regarding which monetary policy framework is most effective in achieving macroeconomic stability and promoting long-term growth. Following that, this study investigated …
