GRAPEVNE - Graphical Analytical Pipeline Development Environment for Infectious Diseases
(Wellcome Open Research, 2025-05-29) Brittain, John-Stuart; Inward, Rhys; Mwanyika, Gaspary; Tegally, Houriiyah; Githinji, George; Tsui , Joseph; Gutierrez, Bernardo; Huynh, Tuyen; Kifle Tessema, Sofonias; McCrone, John T.; Bhatt, Samir; Dasgupta, Abhishek; Ratcliffe, Stephen; Kraemer, Moritz U.G.
The increase in volume and diversity of relevant data on infectious diseases and their drivers provides opportunities to generate new scientific insights that can support ‘real-time’ decision-making in public health across outbreak contexts and enhance pandemic preparedness. However, utilising the wide array of clinical, genomic, epidemiological, and spatial data collected globally is difficult due to differences in data preprocessing, data science capacity, and access to hardware and cloud resources. To facilitate large-scale and routine analyses of infectious disease data at the local level (i.e. without sharing data across borders), we developed GRAPEVNE (Graphical Analytical Pipeline Development Environment), a platform enabling the construction of modular pipelines designed for complex and repetitive data analysis workflows through an intuitive graphical interface

Teaching Methods for Motivating Girls to Learn Science Subjects in Community Secondary Schools in Mbeya, Tanzania.
(African Journals Online (AJOL), 2024-12) Toto, Stella F.; Mngarah, Daniel M.; Bwagilo, Huruma O.
This qualitative study investigated effective teaching methods that motivate girls to learn science subjects in community secondary schools in Mbeya, Tanzania. It focused on participants’ perspectives on these methods and the challenges teachers face in the teaching process. Data were collected from 40 participants across four community secondary schools using observations, interviews, and focus group discussions. The findings revealed that teachers used both teacher-centred and learner-centred approaches to motivate girls to learn science subjects. However, challenges such as overcrowded classrooms, inadequate teaching resources, and poor infrastructure hindered teachers’ efforts to motivate girls to learn science. The study recommends improving the learning environment and resource availability to enhance girls’ motivation and engagement in science subsects within community secondary schools.
The Compound Bacillus and Sea Purslane (Sesuvium Portulacastrum) Enhanced Aquaculture Wastewater Treatment Efficiency: Insights from a Study on Microbial Community Distributions.

As the aquaculture industry continues to grow rapidly, the environmental consequences of wastewater discharge from aquaculture have become a major concern. The biological treatment method has proven to be an effective and beneficial approach for wastewater treatment. In this experiment, aquaculture wastewater was treated using two different ratios of Bacillus subtilis and Bacillus licheniformis composites in combination with sea purslane (Sesuvium portulacastrum) to investigate the wastewater treatment efficiency and microbial community. Sea purslane effectively removed nutrients from aquaculture wastewater. The addition of compound Bacillus significantly increased the removal rates of CODMn, TP, and PO4 3− -P, which were 54.9–56.4 %, 78.2–79.9 %, and 85.0–89.6 %, respectively. Moreover, the compound Bacillus notably influenced the microbial community composition in the water and root systems, reducing species abundance while increasing community diversity, with Treatment 2 exhibiting the highest community stability. The addition of the compound Bacillus significantly increased the relative abundance of Alphaproteobacteria. Most of the important operational taxonomic units (OTUs) that significantly impacted the groups belonged to Alphaproteobacteria. Different biomarkers in the water and root system were primarily from Alphaproteobacteria, Gammaproteobacteria, and Bacteroidia, including Idiomarina and Alteromonas, Ruegeria, Vibrio, Algoriphagus, and Maribacter, among others. These microorganisms play a significant role in promoting the removal rate of nitrogen and phosphorus. Furthermore, the compound Bacillus notably affected the abundance of nitrogen cycle-related sequences and increased the relative abundance of microorganisms associated with the nitrogen cycle. These findings provide valuable insights for optimizing aquaculture wastewater treatment processes.
Sensory Evaluation of Butter and Milk Derived from Oyster Nut.
(MUST Journal of Research and Development (MJRD), 2025-03-31) Shayo, Philipina F.; Emmanuel, John; Oscar, Allen; Balole, Paul; Mlowe, Diana; Sangiwa, Veronica; Runyoro, Joan; Aluko, Angela
This study explores the sensory evaluation of butter and milk made from oyster nuts (Telfairia pedata), a lesser-known but nutritionally rich seed. The evaluation involved a panel of trained assessors who assessed the products on the basis of key sensory attributes, such as appearance, texture, flavour, aroma, and overall acceptability. The oyster nut milk added with strawberry and oyster nut butter with cocoa, sugar, pumpkin seeds and chocolate had higher scores of 7.57 and 6.52, respectively, on overall acceptability. However, as a dairy-free product alternative, oyster nut milk and butter scored highly on sensory evaluations, suggesting significant market potential and positive benefits for cardiovascular health. The two products exhibit potential, though further refinement in processing could enhance its acceptability. These findings suggest that oyster nut-derived products could serve as viable alternatives in the growing market for plant-based dairy substitutes, especially for consumers seeking unique and allergen-free options.
