Postoperative chylothorax following surgical transection of a left ligamentum arteriosum in a cat with a persistent right aortic arch
Pont, Adriaan D.; Bester, Elizabeth G.; Kitshoff, Adriaan Mynhardt (Wiley, 2026-05)
A 6-month-old intact female domestic shorthair cat was presented for surgical correction of a vascular ring anomaly. The main clinical sign on presentation was persistent regurgitation after ingestion of solid food. Computed tomography of the thorax confirmed the diagnosis of a persistent right aortic arch (PRAA) with a left ligamentum arteriosum. The left ligamentum arteriosum was identified, ligated and transected via a left fifth intercostal thoracotomy to relieve the oesophageal constriction associated with the persistent right aortic arch. Within 24 h postoperatively, the patient developed dyspnoea and tachypnoea. A pleural effusion was noted on drainage of the left thoracic drain, which had been placed intraoperatively. The pleural effusion analysis was consistent with a chylothorax. A right-sided thoracostomy tube was placed in addition to the left, and a continuous drainage system was utilised. The chylous effusion resolved on Day 6 postoperatively. This case report highlights the occurrence and management of iatrogenic chylothorax following surgical correction of a PRAA with a left ligamentum arteriosum in a cat.
Postmortem interval estimation based on the developmental patterns of Hemilucilia Segmentaria (Fabricius) (Diptera, Calliphoridae) and Peckia (Euboettcheria) Anguilla (Curran & Walley) (Diptera, Sarcophagidae) : a case in southeastern Brazil

Decaying corpses constitute a relevant source of food resources for a wide range of insects classified as necrophagous. Several blowflies (Diptera: Calliphoridae) and flesh flies (Diptera: Sarcophagidae) species are necrophagous and, for this reason, comprise two of the most relevant families of insects in forensics. Obtaining reliable postmortem interval (PMI) estimates based on entomological traces is of great importance in investigative processes. We present a case report of PMI estimation based on entomological evidence collected in a young woman's corpse found in a wild area from southeastern Brazil, using two Diptera species: Hemilucilia segmentaria (Fabricius) (Calliphoridae) and Peckia (Euboettcheria) anguilla (Curran & Walley) (Sarcophagidae). Additionally, we report for the first time P. (E.) anguilla rearing in a decaying corpse.

Power flow and reliability analysis of a non-isolated PV/grid connected quasi resonant converter for off-board EV charging station
Harini, S.; Chellammal, N.; Bansal, Ramesh C. (Taylor and Francis, 2026)
Growing awareness of greenhouse gas emissions and exhaustion of fossil fuels leads to the adoption of electric vehicles (EVs). However, the major limitations with respect to EV technology are the driving range and charging time. Also, the proliferation of EVs overloads the power grid and paves the way of incorporating renewable energy sources and energy storage devices. The use of multiple sources necessitates the deployment of compact, low-cost, and high-power electronic converters. This paper proposes a novel configuration of a Multi-Source Non-Isolated Quasi-Resonant Converter (MSNQRC) to overcome the limitations in the charging infrastructure. Due to the presence of a quasi-resonant network, the proposed MSNQRC with a single switch can achieve high voltage gain even at low-duty cycles, provide continuous current and low voltage stress. In addition, this paper elaborates on the parametric design of the converter along with PV modeling based on load ratings and the reliability research of MSNQRC by analysing component failures. A prototype model of 300W is built to verify the efficacy of the designed converter model. The results thus obtained validate the designed model and prove that the proposed system can be used for off-board battery charging systems.
Potential for production and use of liquid biofuels as a strategy for developing green and circular economies in Southern Africa
Dlamini, C.S.; Tshidzumba, Ratsodo Phillip; Gotore, T.; Kabia, G.; Munjoyo, R.S.M.; Kachamba, D. (NISC (Pty) Ltd and Informa UK Limited (trading as Taylor and Francis Group), 2026)
The Southern African Development Community (SADC) responded to global calls to address environmental challenges such as high greenhouse gas (GHG) emissions through the use of liquid biofuels. This study assessed the potential of liquid biofuel production in the SADC region with data collected in Malawi, Mozambique, South Africa and Zimbabwe. The results showed that the liquid biofuel industry is struggling. Countries do not have enough resources to support the industry effectively and there is overreliance on international sponsors. In terms of policy and regulatory frameworks most countries are doing well. However, these policies are not implemented effectively. Most countries use sugar-cane to produce bioethanol. Over the years countries, such as Malawi, have attempted to incorporate crops such as cassava (Manihot esculenta) and castor bean (Ricinus communis). Although the industry is not performing well it has contributed massively to livelihood development in all the region.
