Teaching distilleries need transparent instrumentation without proprietary software locks. We assembled temperature, pressure, and condensate flow loggers from documented breakout boards and calibrated them against reference meters on a fifty-liter pilot still. Mass balance closures improved when vapor temperature ramps were aligned with reflux ratio changes noted by operators. Firmware and CAD files were released under permissive licenses for classroom reuse. Student teams reproduced the build with commodity parts, though thermocouple placement remained the largest error source. The platform supports comparative trials on heads cuts without expensive lab gas chromatography for every run.

Highland polytunnels buffer frost but create sharp diurnal soil temperature swings. We compared conventional polyethylene, perforated biodegradable film, and straw mulch under tomato and leafy greens in replicated bays. Sensors at five centimeters depth recorded degree-hours and time above stress thresholds. Biodegradable film moderated peaks similarly to polyethylene during establishment but cooled faster after rainfall events. Straw reduced weed pressure but elevated humidity near the soil surface unless rolled back before irrigation. Economic partial budgets favored biodegradable film where labor for straw management was costly.

Large capital cities dominate urban phenology studies, leaving secondary cities underrepresented. We recruited volunteers to photograph and timestamp first bloom for five ornamental species along transects from dense cores to peri-urban plots. Smartphone metadata was cleaned for timezone drift and duplicate submissions. Bloom advanced several days in warm pockets near asphalt corridors compared with reference parks, consistent with nocturnal heat retention. Model residuals pointed to irrigation and wind channel effects. The dataset is modest but repeatable yearly with minimal infrastructure, supporting municipal greening guidelines.

Shared cellars balance fermentation peaks for many members, complicating efficiency upgrades. We monitored electricity and glycol loop temperatures before and after modular heat-pump retrofits in two cooperatives. Regression models separated weather-driven loads from crush events and cold stabilization. Post-retrofit, baseline kilowatt-hours per hectoliter fell with shorter defrost cycles, though peak demand still tracked simultaneous malolactic tanks. Operators shifted some stabilizations by twelve hours using tariff signals without quality penalties. Lessons include metering granularity and training on setpoint discipline during staff turnover.

Shaded fruiting walls change leaf reflectance and delay visual scab spotting. We captured narrow-band images with a modified snapshot camera on overcast and sunny mornings across three cultivars. Simple normalized difference indices were tested against microscopic counts of sporulating lesions. Two band combinations improved sensitivity relative to color photography alone while keeping false alarms acceptable for advisory use. Hardware notes cover exposure bracketing and stable white reference placement on sloped rows. Findings support targeted single-spray interventions when regional models overpredict infection risk.

Commercial electromagnetic surveys are rarely affordable for fragmented smallholdings. We trained farmer groups to collect GPS-tagged soil samples and hand-held EC readings along transects during the dry season. Data were merged into village-scale maps and validated against gravimetric moisture during two irrigation trials. Zones with high EC and low available water capacity received shorter, more frequent pulses, reducing tail-end runoff. Facilitators documented translation needs and data ownership norms. The workflow trades precision for transparency and faster collective decisions on shared pump schedules.

Late-season botrytis risk depends on within-canopy humidity persistence that station-level weather often misses. We deployed paired temperature and relative humidity loggers at fruit zone height across twelve plots in a cool-climate district. Nighttime leaf wetness proxies were summarized into simple indices and compared with weekly cluster inspections. Plots with tighter clusters and dense basal growth showed longer wetness duration even when regional forecasts were dry. Growers used the indices to time leaf removal without increasing sunburn events. Results highlight affordable logging as a bridge between mesoscale forecasts and hands-on scouting.

This article examines the effectiveness of a public organisation\'s anti-corruption strategy and plan, with a particular focus on how leadership and management practices influence accountability and good governance in the context of South African local government. The study evaluates the extent to which internal control systems, audit mechanisms, and ethical leadership contribute to preventing fraud and corruption within local municipalities. Employing a qualitative research design, data were collected through semi-structured interviews with nine purposively selected participants drawn from three categories — academic researchers, non-governmental organisation (NGO) staff members, and community leaders — with three participants drawn from each group. Thematic analysis was employed to interpret the data, enabling the identification of recurring patterns and insights regarding the municipality’s anti-corruption framework.\nThe findings reveal that leadership commitment and consistent enforcement of internal controls are central to reducing corruption risks. However, significant gaps remain in monitoring processes and employee awareness, which periodically weaken accountability structures. The study further found that effective internal audits, clear reporting lines, and regular independent reviews significantly enhance transparency and organisational integrity. The case of the Emalahleni Municipality in Mpumalanga province serves as a compelling illustration of how leadership instability, inadequate enforcement of disciplinary codes, and systemic weaknesses in internal controls create fertile conditions for corruption to flourish.\nThe significance of this study lies in its contribution to the growing body of literature on public sector governance and anti-corruption policy in South Africa, particularly at the local government level. It offers a practical framework grounded in empirical evidence for strengthening anti-corruption mechanisms, emphasising that efforts must go beyond policy formulation to include strong leadership oversight, continuous evaluation of internal controls, and the fostering of a culture of ethical responsibility at all organisational levels. Strengthening these mechanisms ensures compliance with governance standards and builds public trust in institutional operations.

This article examines how group work impacts learners with low performance in mathematics. One province in South Africa runs an intervention program to help low-achieving learners before their final exams. This program always takes place in June, during school holidays, to boost the success rate of Grade 12 mathematics, focusing on students from low-performing schools. These learners are selected based on overall exam results across all subjects, with two students chosen from each such school across the province. Highly qualified mathematics educators from well-performing schools and tertiary institutions were recruited to assist learners with Euclidean Geometry problems, and one of the authors participated in this program. The teaching approach of one of the authors was solely based on group work. The purpose of this study was to assess whether group work could improve the performance of uniform low-performing students, informed by a review of the literature on group work and participant performance. Most previous studies focused on group work involving students with mixed abilities or heterogeneous groups. The low-performing learners were divided into twelve classes, with each educator assigned three classes. The study relied on pre- and post-test results, which were analyzed quantitatively. The results showed that homogeneous group work among low-performing learners improved their overall performance. Based on these findings, the study suggests that mixed groups of low and high performers tend to produce more successful outcomes.

This study explored how employees perceive transformation at the Gauteng Provincial Legislature in South Africa. The research questions, results, and findings framed the interpretive research paradigm, systems theory as a framework for this study. The first key finding was about the response of employees to change. Data revealed that there was resistance to change due to a lack of open communication, a lack of clarity about the vision for change, and no consultation in most instances. The results further revealed that there was no option but to comply due to the Constitution, policies, and procedures regarding work processes within the Gauteng Provincial Legislature. Given that the participants hold strategic and senior positions within the Legislature, the nature of their roles and responsibilities leaves little room for resistance to change. Rather, they are compelled to lead the change processes. The second key finding concerned the need for a change management framework to enable the successful implementation of the change process. The results revealed that for any change initiative to succeed, setting a compelling vision for change is required. The Third key finding was communication, and its impact on accepting or resisting change. Data revealed that effective communication resolves disputes, resistance to change, enhances teamwork, and successful implementation of the change efforts, while internal compliance involves adhering to the organisation’s internal policies and procedures. The fourth key finding was on work-life balance. Data revealed the necessity to use policies and procedures to support work-life balance. Data revealed that most of the participants felt that insufficient consideration was given to work-life balance.
