NILGIRIS: A sub-adult White-rumped vulture that was GPS-tagged in Maharashtra in 2025 and was seen flying in the Nilgiris district for the past three months was electrocuted to death at Ebbanad near Ooty on Sunday, once again highlighting the threat posed by uninsulated overhead power lines to vultures and other birds.

NILGIRIS: The Nilgiris Government Medical College and Hospital, inaugurated by former Chief Minister M K Stalin a year ago, is yet to deliver the expected benefits. The recent referral of a snakebite patient to the Coimbatore Medical College Hospital (CMCH) has highlighted the absence of a nephrologist at the Nilgiris hospital.

Background Urolithiasis prevention depends on sustained fluid intake, timely urination, and appropriate dietary and lifestyle practices. However, occupational routines may make these behaviors difficult to maintain. This study explored participants’ perceptions of how occupational routines relate to stone-preventive self-care among individuals with CT-confirmed urolithiasis. Methods An observational qualitative exploratory study was conducted at a tertiary care teaching hospital in South India. Adults with CT-confirmed urolithiasis and at least one calculus measuring 3 mm or more were recruited using maximum-variation purposive sampling across physically demanding or heat-exposed, sedentary or professional, travel-based or mobile, and shift-based or irregular work contexts. Face-to-face semi-structured interviews were conducted in Tamil between February and July 2025. Contemporaneous interview notes were expanded after each interview, translated into English, and analysed using thematic analysis. Clinical and CT-related variables were summarized descriptively to characterize the sample. Results Twenty-four of 32 approached participants were included. The median maximum stone diameter was 7 mm (interquartile range, 5–10 mm), 15 participants had hydronephrosis and/or obstructive features, and 9 had recurrent stone disease. Six themes were identified: occupationally shaped inadequate hydration; restricted or delayed urination in relation to work setting; disruption of meal timing and food quality; occupational absorption and neglect of self-care; schedule instability, travel, and disruption of daily routines; and stone disease understood as multifactorial, with occupation interacting with other perceived contributors. Across themes, participants described three interconnected pathways through which work routines could make preventive self-care difficult to sustain: infrastructural and access constraints, schedule instability and routine disruption, and cognitive-attentional absorption. Family history, dietary and lifestyle practices, supplements, smoking, alcohol use, and comorbidities were also described as contextual contributors. Conclusions Occupational routines may influence the feasibility of maintaining stone-preventive self-care among individuals with urolithiasis. The findings support occupation-sensitive counselling and practical workplace strategies that consider water and toilet access, break opportunities, travel demands, shift work, and workload. Longitudinal and implementation studies should assess whether such approaches improve preventive behaviours and stone-related outcomes.

Stringent emission norms and the increasing demand for fuel efficiency have accelerated the development of vehicles with alternative power plants, such as batteries, ultracapacitors, and fuel cells. While battery electric vehicles (EVs) reduce crude oil dependency, they suffer from range anxiety. Hybrid electric vehicles (HEVs) offer a feasible solution, improving fuel economy and reducing emissions. This research focuses on designing optimal energy management strategies (EMS) for a full-parallel HEV using heuristic rule-based and advanced dynamic programming approaches to manage power distribution between the internal combustion engine and the electric motor. An efficient forward-facing dynamic model of the hybrid powertrain was developed using MATLAB Simulink, incorporating a real-time legislative driving cycle. Integrating actual testing data enhances the real-time effectiveness of the developed EMS. Results indicate these strategies can significantly reduce fuel consumption, maintain battery state of charge (SoC) levels, and enhance overall vehicle performance by up to 15–60% compared to conventional diesel engine-based vehicles. The simulated results are in good agreement with the experimental results guaranteeing the controller’s peak performance in real-world scenarios. Moreover, the modified dynamic programming control strategy performs better than the rule-based and dynamic programming strategies in terms of battery charge sustenance and vehicle efficiency. This research provides crucial insights, advancing hybrid vehicle technology and promoting environmental sustainability.
