Exploring Consultancy-Related Variations In Public Building Projects: A Review Towards A Management Framework, Grayson Bambaza, Ismail W. R. Taifa, George S, Mwaluko

Tanzania Journal of Engineering and Technology (TJET)

Consultancy-related variations remain one of the leading causes of cost overruns, schedule delays, quality deficiencies, and contractual disputes in public building projects. Although various studies have been undertaken to document the causes of variations in construction works, the same level of interest has not been shown for consulting services variations across the consulting services spectrum and their consequences for effective management. This study explores variations in consulting services for public works by systematically reviewing the existing literature using the PRISMA (Preferred Reporting Items for Systematic reviews and Meta Analyses) guidelines. Relevant articles published from 2020 to 2026 were retrieved from …

Decision Support Tool For The Maintenance Of Meter Gauge Railway Permanent-Way Infrastructures: A Concept Paper, Hamisi J. Maulid, Beatus A.T Kundi, Juma M. Matindana, Ismail W. R. Taifa Dr

Tanzania Journal of Engineering and Technology (TJET)

A Decision Support Tool (DST) represents a transformative way of modernising maintenance practice on the permanent-way infrastructure of Meter Gauge Railway (MGR). Maintenance practice remains largely reactive, as the MGR plays a strategic role in transporting both freight and passengers, resulting in inefficient resource allocation, high operational risk, and growing Lifecycle expenses. This concept paper explores the potential and the design challenges for a DST that combines fuzzy analytic hierarchy process (Fuzzy-AHP) modelling, multi-criteria decision analysis (MCDA), Geographic Information Systems (GIS) and predictive machine learning (ML) analytics for evidence-based, future-oriented maintenance management. The paper draws on peer-reviewed studies from …

Fifty Years After Estelle V. Gamble—Where Does Carceral Health Law Go From Here?, James René Jolin, Jenean Docter, Benjamin A. Barsky

Faculty Scholarship

Fifty years ago, the US Supreme Court decided Estelle v.Gamble—a landmark case commonly known for establishing a duty on the government to provide health services to incarcerated people, whether before or after conviction. In this column, we offer a brief critical reappraisal of Estelle by reviewing its demanding legal standard and identifying a set of related litigation barriers that stymie the availability of relief in federal court. Given these constraints, we argue for a carceral health law paradigm that moves beyond the current, dominant focus on litigation.We use Medicaid law and policy as a case study to explore the …

Differentiating Aetiologies In Perimesencephalic Sah: Clinical Insights Into Basilar Artery Perforator Aneurysms, Italo Linfante

All Publications

Background/objective: Perimesencephalic subarachnoid haemorrhage (pmSAH) has traditionally been considered benign and of venous origin. However, advanced imaging increasingly identifies basilar artery perforator aneurysms (BAPAs) as a subset of cases historically labelled as non-aneurysmal, atraumatic (NAA) pmSAH. The objective was to compare clinical characteristics and outcomes of patients with NAA, BAPA and ruptured posterior circulation aneurysms (r-pc-AN), assessing the impact of pmSAH aetiology on patient outcomes.

Methods: This retrospective, multicentre, observational cohort study included BAPA cases from the international PERForator Aneurysm registry (2013-2025, 60 centres, 19 countries). Comparison cohorts were from a single high-volume tertiary care centre (2004-2025). The study included …

Discovery Of Ro 41-0960, A Non-Steroidal Inhibitor Of The Na+/K+-Atpase, Carlos Cruz-Cortés, Jaroslava Šeflová, Guadalupe Guerrero-Serna, Eric N. Jimenez-Vazquez

Health & Biomedical Sciences Faculty Publications

The Na⁺/K⁺-ATPase (NKA) is a central regulator of cardiac ion homeostasis and a validated target for heart failure. Yet, cardiotonic steroids used in clinical practice are limited by a narrow therapeutic window and pro-arrhythmic effects. Here, we identify Ro 41-0960 as a non-steroidal inhibitor of NKA with a distinct mechanistic profile. The compound inhibits NKA activity with IC50 values of 17.9 ± 1.1 µM for purified enzyme and https://doi.org/10.3 ± 1.1 µM in microsomal preparations. ATP-dependent activity measurements revealed a non-monotonic response in which inhibition was most pronounced at ATP concentrations below 4 mM and diminished …
