Sarayut Malai, Lamay Junthakhao, Donrudee Sookjai, Thiranan Sonkaew — Tue, 01 Jul 2025 00:00:00 +0700

Trees play a crucial role in capturing carbon dioxide and storing it as biomass. One method to estimate carbon dioxide equivalent absorption and storage in trees is through measuring biomass using the Allometric equation, which utilizes height and circumference information. This research aims to compare tree height measurement tools using a traditional height measuring pole and laser rangefinder camera. A sample group of 97 trees of general deciduous types within a 15,605.10 square meter area of Rajabhat Lampang University was studied. The heights measured by both methods were averaged and categorized into five height classes (H-Class): 2-4, 4-6, 6-8, 8-10, and higher than 10 meters. The average heights measured using the traditional measuring pole were 3.467, 5.033, 6.980, 9.180, and 11.117 meters, respectively. The heights measured with the laser rangefinder yielded averages of 3.290, 4.909, 6.876, 9.062, and 10.940 meters, respectively. Statistical analysis revealed no significant difference between the two measurement tools at a 95% confidence level and the correlation coefficient (R²) value of 0.996. Furthermore, considering measurement errors from three different observers using the laser rangefinder and repeating measurements, no significant differences were found at a 95% confidence level. Calculations for carbon storage in trees using both methods resulted in 19,329 and 19,126 kilograms of carbon dioxide equivalent (kgCO2eq), respectively, with a difference of 1.3%.

This research aims to provide preliminary detection of alkaloids. Total phenolic content was determined using the Folin–Ciocalteu method, and antioxidant activity was tested from the stems and leaves of Glycosmis pentaphylla (Retz.) DC. using the DPPH assay and FRAB assay. 40% Ethanol was used as a solvent. The results of the determination found alkaloids in both the stems and leaves. The total phenolic content in the stem and the leaf extracts was equal to 351.22 ± 15.82 and 329.85 ± 24.63 mg of gallic acid equivalent/g crude extract, respectively. Antioxidant activity was determined for the stem and leaf extracts at a concentration of 1 mg/mL. Its % inhibition of free radicals (DPPH) was equal to 70.10 ± 5.22 and 26.73 ± 6.10 µg/mL, respectively. While the standard Trolox® had a % inhibition of DPPH free radical of 98.85 ± 2.01 µg/mL. Stem and leaf extracts showed TEAC of 393.71 ± 4.86 and 207.20 ± 21.03 µg/mL, respectively. This study shows that the extracts of the stems and leaf of G. pentaphylla (Retz.) DC. exhibited antioxidant activity through multiple mechanisms, both direct free radical scavenging and chain reaction inhibition by the main active compounds in the alkaloid group. In addition, the stem extract of G. pentaphylla (Retz.) DC. had higher total phenolic content than the leaf extract. As a result, the stem extract has better antioxidant activity than the leaf extract. Consequently, the stem sections may be used in place of the leaf.

Tomeyot Sanevong Na Ayutaya — Tue, 01 Jul 2025 00:00:00 +0700

A trade deficit often indicates that a country is consuming more goods than it can produce itself. A trade deficit can have both positive and negative impacts on the economy of a country. Therefore, forecasting the overall value of imports and exports of a country in advance is very beneficial for strategic planning to manage potential problems arising from a trade deficit. For these reasons, this research studies, analyzes, and compares time series models that can be used to predict the overall volume of imports and exports using statistical methods and machine learning methods including DNN, LSTM, ARIMA, and Prophet. The Mean Squared Error (MSE) values are 0.4116615060290905, 0.9943514149915439, 0.5022269255490994, and 1.4212623390468428, respectively, while the Root Mean Squared Error (RMSE) values are 0.6416085302028727, 0.9971717078776071, 0.7086797058961822, and 1.1921670768171897, respectively. The experimental results conclude that the DNN model provides the highest efficiency in forecasting both the import and export volumes of goods and services for the country.

Optimization of Oligosaccharide Extraction from Sponge Gourd Using Response Surface Methodology and Evaluation of Prebiotic Properties

Tue, 01 Jul 2025 00:00:00 +0700

Sponge gourd (Luffa aegyptica or Luffa cylindrica (L.) M. roem) is a local plant in the Cucurbitaceae family that is widely consumed in Thailand. A previous study demonstrated the potential of sponge gourd extracts in modulating gut microbiota in animal studies. This research aimed to determine the optimal conditions for extracting oligosaccharides from sponge gourd using hot water extraction to evaluate their prebiotic potential. Key extraction factors influencing oligosaccharide yield were examined, including 1) extraction temperature (X₁) at 50, 70, and 90 °C, 2) solid-to-liquid ratio (X₂) at 1:10, 1:20, and 1:30, and 3) pH (X₃) at levels 2, 5, and 8, using Response Surface Methodology (RSM) with a Box-Behnken design (BBD). Our findings showed that increased extraction temperature and pH significantly enhanced yield, while the solid-to-liquid ratio had no significant impact on the yield. The highest yield was achieved at 90 °C and pH 8. Under these conditions, extracts were evaluated for prebiotic properties, assessing their tolerance in simulated gastrointestinal conditions and their impact on probiotic growth. Results demonstrated that the non-reducing sugars, representing oligosaccharides from sponge gourd, showed 87.72% resistance to digestive breakdown. Additionally, the extracts promoted the growth of three tested probiotic strains: Lactobacillus plantarum 299V, Lactobacillus casei Shirota, and Lactobacillus rhamnosus LGG. This highlights the potential of sponge gourd extract as an effective prebiotic, comparable to commercial alternatives. Future research should concentrate on purifying sponge gourd oligosaccharide extracts and exploring their functional properties in combination with probiotics to facilitate their development into health-enhancing food products.
