Heat Retention Efficiency of Legume-Based Hot Compress Bags for Thai Traditional Medicine Applications

Fri, 10 Oct 2025 00:00:00 +0700

Heat therapy is a highly effective treatment modality in Thai traditional medicine, primarily used to alleviate musculoskeletal discomfort, joint diseases, and circulatory system conditions. This study aimed to assess the thermal retention efficacy of hot compress bags made from locally sourced legume grains in Northeast Thailand. Seven varieties of legumes were chosen: mung bean, cowpea, soybean, hyacinth bean, jicama bean, peanut, and kidney bean. Each was combined with mung beans in a 1:1 ratio, amounting to 200 grams per cotton bag. Heat treatment was conducted using an 850-watt microwave for 2 minutes, with temperature readings taken every minute over a total duration of 15 minutes. The experiment was conducted nine times and examined with descriptive statistics and one-way ANOVA. The mung bean-cowpea mixture exhibited exceptional heat retention, starting at 68.00±0.70°C and concluding at 37.33±1.41°C, indicating a mere 45.1% heat loss. This combination sustained a therapeutic temperature range of 40-45°C for 12.5 minutes, which is ideal for physiotherapy applications. Statistical analysis indicated significant differences (p < 0.05) among the different legume combinations. This research demonstrates the potential of legume grains as effective heat retention media for hot compress bags in Thai traditional medicine applications, thereby adding value to local agricultural products.

The Viscosity of Glycerin Based on Stokes’s Law and the Landau-Lifshitz Equation Tested with the Underdamped Hamonic Oscillation Experiment

Tue, 28 Oct 2025 00:00:00 +0700

This research aimed to study the viscosity between the Landau-Lifshitz equation model and Stokes' law by underdamped harmonic oscillation. The data of the steel ball's movement is collected and processed by tracker program to find the resistance coefficient () and the angular velocity of the vibration (). Comparison of viscosity values from viscosity meter. The results showed that and the viscosity value increased with the concentration of glycerin, but the value decreased. The viscosity values from the Landau-Leifsitz equation are close to the values obtained from the instrument. The Stokes' law can be used to describe the viscosity values while constant velocity, unlike the Landau-Leifsitz model equations which consider the effect of objects at non-constant velocity. When studying the relationship between the value of and viscosity, it was found that the tendency increased with the length of spring extension. At the stretch distance of 2 cm, there was less in-plane oscillation. Hence, the viscosity at the stretch distance of 2 cm close to the measured instrument, but at 70% glycerin concentration, the value was more than 70% different from the measured instrument. However, at 70% glycerin concentration, the value is more than 70% different from the measurement device. One of the reasons is that at high concentrations, some of the glycerin is attached to the object's surface. Therefore, it was concluded that the stretch distance of 2 cm and the concentration of 10%, 30%, and 50%, the experimental viscosity was consistent with the measuring instruments which are suitable for developing classroom teaching.

This paper employs the Simple Equation (SE) method in conjunction with Jumarie’s modified Riemann–Liouville fractional derivative to derive exact solutions for the space–time fractional modified Benjamin–Bona–Mahony (mBBM) and Zakharov–Kuznetsov Benjamin–Bona–Mahony (ZKBBM) equations. The obtained exponential-type solutions describe kink-shaped traveling waves, which are illustrated through 2D, 3D, and contour plots using suitable parameters. The results confirm the efficiency and reliability of the proposed method as a robust analytical technique for deriving traveling wave solutions in nonlinear fractional models encountered in science and engineering. This study extends the SE method within the framework of Jumarie’s modified Riemann–Liouville fractional derivative, broadening its applicability to space–time fractional systems. The approach establishes a new analytical framework for fractional traveling wave solutions, and the derived results uncover additional dynamical behaviors of the mBBM and ZKBBM equations, demonstrating both the originality and effectiveness of the proposed method.

Resistance Mechanisms and Dissemination of Resistance Genes in Gram-negative Bacteria from Wastewater Treatment Systems: Environmental Risk

Sureeporn Aeamsri — Fri, 14 Nov 2025 00:00:00 +0700

Antimicrobial resistance (AMR) is a global public health threat, particularly among Gram-negative bacteria that possess multiple resistance mechanisms, including enzymatic degradation, target modification, and antibiotic efflux. Wastewater treatment systems receiving discharges from hospitals, pharmaceutical industries, and community wastewater are recognized as major hotspots for the accumulation and dissemination of antibiotic-resistant bacteria (ARB) and resistance genes (ARGs) through horizontal gene transfer (HGT). This narrative review summarizes current knowledge on bacterial resistance mechanisms, environmental dissemination pathways, and recent technologies for AMR mitigation in wastewater systems. Evidence indicates that conventional treatment processes cannot completely remove resistance genes, highlighting the need for advanced disinfection methods such as ultraviolet irradiation, ozonation, and advanced oxidation processes. Strengthening source control by limiting the discharge of antibiotics and heavy metals and adopting the “One Health” framework that integrates human, animal, and environmental health are essential for effective and sustainable AMR management.
