The clarification of pivotal factors influencing the quality of coconut sap after harvesting is of paramount importance for fostering mutual benefit between the involved parties. This research focuses on assessing the quality and degradation of coconut sap during the post-harvest stage. It addresses the shortcomings in evaluating coconut sap quality and improper pick-up conditions. To improve these processes, various experiments were designed, including 1) preliminary experiments that explored microbial count, pH, and soluble solids in harvested coconut sap at varying intervals, and 2) the L9 Taguchi Orthogonal Array method...

Foreign body ingestion is an infrequent cause of small bowel obstruction and, rarely, perforation. It is a common occurrence among pediatric patients, mentally impaired and the edentulous elderly population majority of which will pass through the gastrointestinal tract uneventfully. The likelihood of complications such as perforation, bleeding or fistula formation increases markedly particularly for sharp, stiff, and elongated objects (i.e. toothpicks, meat bones, pins, and razor blades). Diagnosis can be difficult as frequently patients are incognizant of the nature and time of ingestion...

For complete details on the use and execution of this protocol, please refer to Whittaker et al...

In building cooling, the demand for cooling surges during specific times, stressing air-conditioner operation, and additional cooling is often wasted during low-demand periods. Water-phase change material (W-PCM)-based thermal energy storage (TES) allows for load shifting and effective management of peak demand by storing cooling energy when the demand is low. This stored energy can be deployed during peak hours, decreasing energy usage and associated CO2 emissions. However, the use of W-PCMs was hindered by phase separation, slow energy transfer, and high supercooling degree (SCD)...
