Sustainable urban transportation planning: Integrating an electrified metro system into Kampala metropolis
(Elsevier Ltd, 2024-11-21) Kimuli, Ismail;; Kirabira, John Baptist;; Nkambwe, Ismael ;; Nakyejwe, Saadat L.K.;; Lubwama, Michael;; Sendawula, Kasimu;; Nabaggala, Nashua K
Electrified metro critical.•Policy shifts vital.•Multi-modal integration.•Renewable energy focus.•Kampala-specific solutions. With the United Nations (UN) predicting that 60% of the global population will reside in cities by 2050, sustainable transportation planning is a prominent global trend. This study examines Kampala's transportation sustainability and addresses existing knowledge gaps. It leverages the TIMES-VEDA model, an acronym for “The Integrated MARKAL-EFOM System - Versatile Data Analyst.” TIMES-VEDA is an engineering optimizer used to explore four scenarios: Business-as-Usual (BAU), Reduction in Electricity Consumption (REC), Renewable Electricity Portfolio (REP), and Carbon Reduction Target (CRT). These scenarios analyze the inherent aspects of the Kampala metropolis energy system, providing a foundation for evidence-based decision-making. The approach aligns with the United Nations’ Sustainable Development Goals (UN's SDGs 7, 11, & 13), Uganda's Vision 2040, and the third National Development Plan (NDPIII). The analysis demonstrates that sustainability is within range and highlights the imperative of a holistic approach, the potential of mass rapid transit, anchored by an electrified metro system, to advance green mobility. It sheds light on sustainable practices and trade-offs among distinctive pathways, suggesting a mix of policy measures to combat climate change. The KAMPALA-TIMES model, a bottom-up framework, reveals that a region-specific policy package, particularly the CRT scenario, achieves significant decarbonization, promoting eco-friendly multimodal transportation and paving the way for a more sustainable future for Kampala until 2060. The findings inform policy on urban planning and sustainable transportation that is adaptable elsewhere, ensuring long-term environmental and economic resilience.

Spectrophotometric analysis of artesunate injections availablein community pharmacies in Northern and Western Uganda
(Taylor & Francis group, 2025-06-12) Ayogu, Ebere Emilia;; Ngolryeko, Emmanuel Aryon;; Ezeonwumelu, Joseph Obiezu Chukwujekwu ;; Wawata, Ibrahim Garba;; Sadiq, Bashir Olaniyi
The surge in different brands of artesunate injection in Uganda, has raised the need for this study, which aimed at quantifying the actual amount of artesunate in different brands of artesunate injections available in Northern and Western Uganda.AIMThe surge in different brands of artesunate injection in Uganda, has raised the need for this study, which aimed at quantifying the actual amount of artesunate in different brands of artesunate injections available in Northern and Western Uganda.The wavelength at maximum absorbance of pure artesunate powder was determined using Ultraviolet-visible spectrophotometer and Beer Lambert's plot was generated. This was validated and used to assay 27 brands of artesunate.MATERIALS AND METHODSThe wavelength at maximum absorbance of pure artesunate powder was determined using Ultraviolet-visible spectrophotometer and Beer Lambert's plot was generated. This was validated and used to assay 27 brands of artesunate.In the spectrophotometric assay method used, Beer Lambert's law was obeyed within the range of 20 µg/ml-140 µg/ml with linear regression equation of y = 0.012 + 0.030 and correlation coefficient of (R2) 0.999 (n = 9). The limits of detection (sensitivity) and quantification were found to be 0.83 mg/ml and 2.09 mg/ml respectively. About 66.6% (18) and 33.3% (9) had actual artesunate content higher and lower than labeled claim respectively, while 40.7% (11) had deviations from labeled claim that were within acceptable limits.RESULTSIn the spectrophotometric assay method used, Beer Lambert's law was obeyed within the range of 20 µg/ml-140 µg/ml with linear regression equation of y = 0.012 + 0.030 and correlation coefficient of (R2) 0.999 (n = 9).

Towards Improved Geometry Instruction: Learners’ Experiences with Technology-Enhanced and Conventional Van Hiele Phased Instruction
(International Consortium for Research in Science & Mathematics Education (ICRSME), 2025-07-02) Issa Ndungo; Sudi Balimuttajjo; Edwin Akugizibwe
This study investigated learners' experiences and understanding of transformation geometry using two instructional strategies: Conventional Van Hiele Phased Instruction (CVHPI) and Technology-Enhanced Van Hiele Phased Instruction (TVHPI), incorporating GeoGebra as a digital tool. Through semi-structured interviews, qualitative data were collected from 48 Senior Three secondary school learners who participated. Thematic analysis revealed that TVHPI, supported by GeoGebra, enhanced visual learning and dynamic interaction with geometric concepts, though learners faced technical challenges and limited practice time. CVHPI, while providing structured and step-by-step instruction, particularly benefited lower achievers but was less effective in addressing complex misunderstandings. As a result of this study, a Geometry Pedagogical Improvement Cycle (GeoPIC) framework was developed to improve the teaching and learning of geometry through a continuous and systematic process. The GeoPIC framework emphasizes adopting instructional strategies, tailoring them to individual needs, aligning with learner expectations, and incorporating feedback through a cyclical reflection and adjustment process. This study highlights the potential of combining technology-enhanced tools with conventional instruction and presents GeoPIC as a model for refining pedagogical approaches in geometry education.

Prevention messages and AIDS risk behavior in Kampala, Uganda
(Informa UK Limited, 2011-06-16) Hearst, Norman; Kajubi, Phoebe; Hudes, Esther Sid; Maganda, Albert K.; Green, Edward C.
Uganda was one of the first countries to substantially reduce HIV rates through behavior change, but these gains have not continued in recent years. Little is known about what messages Ugandans are currently hearing about AIDS prevention, what they themselves believe to be important prevention strategies, and how these beliefs are associated with behavior. We interviewed men and women aged between 20 and 39 in two poor peri-urban areas of Kampala, using a random sample, cross-sectional household survey design. Respondents provided detailed reports of sexual behavior over the past six months, the main prevention message they are currently hearing about AIDS, and their own ranking of the importance of prevention strategies. Condom use was the main AIDS prevention message that respondents reported hearing, followed by getting tested. These were also what respondents themselves considered most important, followed closely by faithfulness. Abstinence was the lowest ranked strategy, but a higher ranking for this prevention strategy was the only one consistently associated with less risky behavior. A higher ranking for condoms was associated with higher levels of risk behavior, while the ranking of testing made no difference in any behavior. These results present challenges for AIDS prevention strategies that rely primarily on promoting condoms and testing. HIV prevention programs need to assess their impact on behavior.

History, evolution and future of environmental health in Uganda
(Informa UK Limited, 2018-12-03) Ndejjo, Rawlance; Atusingwize, Edwinah; Oporia, Frederick; Ssemugabo, Charles; Musoke, David; Ssemwanga, David K.; Halage, Abdullah Ali; Isunju, John Bosco; Kansiime, Winnifred; Mubeezi, Ruth; Mugambe, Richard Kibirango; Mbaha, Emery Patrice; Luyima, Paul; Ssempebwa, John C.
This article explores the history and evolution of Environmental Health in Uganda under four key themes: training and practice; research; governance, policy and regulatory framework; and challenges. The article also describes the future of the profession. Through a review of documents and key informant interviews, it is noted that Environmental Health in Uganda dates back to colonial times when the country was affected by diseases including plague, trypanosomiasis and small pox. Concerted efforts were advanced to train cadres that would improve the sanitation status and address the prevailing disease burden. Over several decades, the Environmental Health profession has evolved in many areas of training, practice, research and governance, policy and legal framework amidst several challenges. The future of Environmental Health in Uganda will require more advanced training and research, broadened practice, and streamlined governance.
