Using Internet of Things (IoT) technologies and Private Cloud data processing, this study aims to (1) find out how heatstroke occurs in people who are outside, especially when they are dehydrated or have impaired thermoregulation; (2) create an automated real-time monitoring and heat warning system; and (3) assess how well the system works to prevent heat-related illnesses. The study involved creating a prototype that can independently use external environmental sensors to evaluate temperature, humidity, and air pressure. A mean fusion technique was utilized to combine sensor data with meteorological data sourced from the OpenWeatherMap API, thereby improving the accuracy of the study. The K-Nearest Neighbor (KNN) method was utilized to analyze the aggregated data and evaluate the likelihood of an individual experiencing heatstroke. The model achieved peak performance at k = 3, demonstrating an accuracy of 86.67% in recognizing high-risk heat scenarios. The system was equipped with automated notifications that delivered accurate real-time alerts. Groups participating in outdoor activities, such as students in outdoor classes, athletes undergoing training, and workshop attendees exposed to sunlight, took part in field trials. The evaluation findings indicated that consumers expressed a high level of satisfaction, achieving an average rating of 4.37 out of 5.00 (87.44%). The device control function achieved an impressive satisfaction rating, with an average score of 4.54 (90.80%). The findings demonstrate that the method we proposed serves as a dependable, cost-effective, and scalable solution for tracking local temperature levels and reducing the risk of heatstroke. This method can be utilized in educational settings and various outdoor locations where proactive management of heat-related health issues is essential.

Efficiency of 3 Fungicides (Prochloraz, Cyproconazole, and Pyraclostrobin) for Controlling Lasiodiplodia theobromae Causing Fruit Rot in Durian

2026-02-20T16:04:18+07:00

Durian fruit rot disease has caused severe economic losses to farmers, leading to premature fruit drop and decrease fruit yields. Effective measures are essential for preventing and controlling this disease. This study aims to evaluate the efficacy of three fungicides—prochloraz, cyproconazole, and pyraclostrobin—against Lasiodiplodia theobromae, the causal agent of durian fruit rot. The study began with the isolation of the pathogen from symptomatic durian fruits. Molecular identification confirmed the presence of L. theobromae, with three isolates identified: LT-1, LT-5, and LT-10. Pathogenicity tests conducted on 70-day-old pruned young durian fruits revealed that the LT-10 isolate caused the most severe infection, reaching 100% disease incidence. To assess fungicidal efficacy, the poisoned food technique was employed at five concentration levels (0, 10, 100, 500, and 1000 mg/L). The results demonstrated that prochloraz effectively controlled LT-10 at all tested concentrations. At 10 mg/L and above, fungal growth inhibition ranged from approximately 75% to 100%. A dipping test was subsequently conducted on durian fruits using three fungicides—prochloraz, cyproconazole, and pyraclostrobin—each applied at a rate of 100 g per 100 L of water. Among them, prochloraz exhibited the highest efficacy, achieving an 80% fungal growth inhibition rate, followed by cyproconazole and pyraclostrobin. Dissection of treated durian fruits revealed no LT-10 infection in the fruit pulp across all treatments. In conclusion, the results of this study demonstrated that prochloraz at concentrations of 10, 100, 500, and 1,000 mg/L effectively inhibited the fungal pathogens causing durian fruit rot under laboratory conditions. However, further studies under field conditions are required to evaluate its efficacy, suitability, and safety before practical application in commercial durian orchards.

2026-02-20T16:04:16+07:00

This study investigates the effects of niobium (Nb) and iron (Fe) co-doping on lead-free Ba_0.945Ca_0.055(Ti_0.9946-xSn_0.0054)(Nb_0.5Fe_0.5)_xO₃ ceramics denoted as BCTS-xNF, where x = 0.00, 0.01, 0.02, and 0.03. The ceramics were synthesized using the solid-state combustion method. The objective of this work was to examine the influence of Nb and Fe co-doping on the crystal structure, microstructure, electrical properties, and magnetic properties of the ceramics. X-ray diffraction (XRD) analysis revealed that all samples exhibited a pure perovskite structure, with a structural transition from tetragonal to cubic symmetry as the doping concentration increased. Dielectric measurements indicated that the Curie temperature (T_C) decreased with increasing x, accompanied by a gradual weakening of ferroelectric properties. Microstructural analysis using scanning electron microscopy (SEM) showed that the sample with x = 0.02 possessed the largest average grain size and the highest density. Magnetic characterization performed using a vibrating sample magnetometer (vibrating sample magnetometer; VSM) demonstrated that Nb and Fe co-doping induced magnetic behavior in the BCTS ceramic system, with the x = 0.02 composition exhibiting the most pronounced magnetic response.
