Abstract

Ao Nang, a coastal tourist city in Krabi Province, has been developing its area to support both Thai and foreign tourists since 1983. This research selected Landsat 1 satellite imagery from 1973, which was before tourism development, to conduct this research. The objective of this research is to analyze the changes in land use patterns between 1973 and 2025, and to model future land use using the CA-Markov model in Ao Nang. The results found that in 1973, the city, town, and commercial areas covered an area of 9.38 km2 (7.82% of the total area), and in 2025, the area increased to 21.95 km2 (18.31% of the total area). Urban expansion has affected other types of land use, such as evergreen forest and various agricultural areas, such as para rubber and mixed orchard. During 1973–2025, urbanization has occurred in important beach areas, such as Nopparat Thara Beach, Ao Nang Beach, Railay Beach, Tubkaek Beach, and Khlong Muang Beach; and important highways along the line, such as 4201, 4203, 4034, and 6024. The results of the Cellular Automata Markov Model (CA-Markov Model) show the simulation of future land use, which occurs in 2050. The CA-Markov model predicts that urban and built-up areas will expand significantly to 40.32 km2 by 2050, representing an 83.7% increase from the baseline. Conversely, forest cover and agricultural land are projected to decline by 18.78% and 12.72%, respectively. The results show that in the next 25 years, the city, town, and commercial areas will expand the most, followed by shrimp farms. If land use changes occur without control, it may affect the use of such land to increase rapidly. However, the research results this time have shown land use data in spatial form that is useful for planning land use development in the coastal tourist city of Ao Nang effectively. Furthermore, this information will support decision-making in preparing for spatial development for sustainable tourism.

Abstract

About 51% of all occurrences of blindness worldwide are caused by cataracts, which are the most common cause of blindness. According to the Rapid Assessment of Avoidable Blindness (RAAB) survey conducted in Indonesia between 2014 and 2016, East Java had the highest rate of blindness (4.4%), with cataracts accounting for 81.1% of cases. Approximately 10,000 cataract cases were reported at the Undaan Eye Hospital in Surabaya, one of the major eye hospitals in East Java, in 2023. This study aims to analyze the recovery time of patients undergoing cataract surgery on both eyes, considering the influencing factors. Data from bilateral cataract patients at the Undaan Eye Hospital in Surabaya between January 2023 and December 2024 were utilized. Gender, age, history of hypertension, heart disease, diabetes, gastric illness, stroke and cholesterol were among the characteristics that were examined. To determine the relationship between the recovery durations of both eyes following surgery, a bivariate survival analysis with Clayton and Gumbel copula functions was used for the analysis. The Gumbel copula was determined to be the better model for describing the recovery of bilateral cataract patients, with a QIC value of 1529.078 and a Kendall's Tau of 0.6636, indicating a moderate and positive dependency between the recovery periods of the right and left eye. The model estimate results showed a substantial correlation between recovery time and a few covariates, including age (hazard ratio of 0.516), history of hypertension (hazard ratio of 0.357), and history of diabetes (hazard ratio of 0.615). Compared to younger individuals, older patients recover more slowly. Furthermore, people with a history of diabetes and hypertension typically recover at a lower rate than those without these conditions.

Abstract

Malachite green (MG) is a persistent and toxic triphenylmethane dye. This dye is widely used in textile industries, contributing to significant contamination of aquatic environments. The development of selective and efficient separation methods for MG therefore remains an important challenge. In this study, MG transport was investigated using a polymer inclusion membrane (PIM) incorporating poly-bisphenol A diglycidyl ether (Poly-BADGE 2:1) as a carrier. The effects of key operational parameters, as well as the presence of competing metal ions (i.e., Pb(II) and Cu(II)), were systematically evaluated. The membrane was prepared using Poly-BADGE 2:1 as the carrier, polyvinyl chloride as the base polymer, and dibenzyl ether as the plasticizer. MG concentration was determined by UV–vis spectrophotometry at 617 nm, while membrane characteristics before and after transport were analyzed using Scanning Electron Microscopy (SEM) and Fourier-Transform Infrared (FTIR) instruments. The results showed that MG transport reached 90.90% under optimal conditions (source phase pH 7, receiving phase 1.25 M HNO₃, membrane thickness T54, carrier concentration 0.09 M, and transport time of 24 h). In the presence of Pb(II) and Cu(II) ions, the transport efficiency decreased to 85.67%, compared to 91.32% without metal ions, suggesting competitive interactions at the carrier sites. These findings demonstrate that Poly-BADGE-based PIMs provide an effective and selective system for MG separation, with good structural stability and promising potential for wastewater treatment applications.

Abstract

The rapid emergence of digital technologies and the increased of using intelligent devices have led to a significant increase in crime incidents. Therefore, there is an emerging need to develop highly accurate and efficient detection frameworks. Hence, this work introduces an intelligent drone-assisted crime-detection system based on a novel Puma Multilayer Perceptron Detection Framework. The images are collected from a Kaggle dataset. The image dataset is pre-processed in a Python environment, with image quality improved by removing noise and normalizing the images. Further, discriminative image features are selected by the Puma Optimization Algorithm. It efficiently selects the optimal features by balancing between detection accuracy and dimensionality reduction. The optimized feature set is then classified using a multilayer perceptron. All these processes aim to accurately detect criminal activities. The efficiency of the proposed model is evaluated using standard metrics, including accuracy, precision, recall, F-score, and error rate, and the results are compared with those of traditional detection approaches. The experimental results show that the proposed framework improves detection accuracy and reliability, making it effective for intelligent drone-based crime monitoring.

Abstract

The accelerating global crisis of antimicrobial resistance and oxidative stress-related diseases has intensified the search for novel therapeutic agents derived from natural sources. Polyphenolic compounds, abundant in many medicinal plants, have emerged as key candidates due to their potent antioxidant and antimicrobial properties. Ruta chalepensis L., a perennial species belonging to the Rutaceae family, is traditionally used in Mediterranean ethnomedicine for its antiseptic, anti-inflammatory, and digestive properties. In Morocco, where phytotherapy forms a cornerstone of rural healthcare practices, this species remains underexplored despite its wide distribution across the Middle Atlas and Rif regions. The present study aims to determine the phytochemical profile and its biological activity of Moroccan R. chalepensis by conducting a comprehensive organ-specific analysis. Methanolic extracts from the plant’s flowers, leaves, and stems were evaluated for their total phenolic content (TPC) and total flavonoid content (TFC) using the Folin-Ciocalteu and aluminum chloride colorimetric methods. Antioxidant potential was assessed through DPPH radical scavenging and ferric reducing antioxidant power (FRAP) assays, while antibacterial activity was tested against Staphylococcus aureus ATCC 29213, Pseudomonas aeruginosa ATCC 9721, and Streptococcus sp. CCMM/B24 using disc diffusion and minimum inhibitory concentration (MIC) protocols. Among all plant parts, floral extracts exhibited the highest TPC (160 ± 2.38 mg GAE/g DW) and TFC (30.1 ± 1.32 mg QE/g DW), alongside superior antioxidant activity (DPPH IC₅₀ = 23.1 ± 1.15 μg/mL). Notably, Gram-positive strains showed greater susceptibility to the extracts, with S. aureus being the most affected. These results underscore the therapeutic potential of Ruta chalepensis, particularly from Moroccan chemotypes, as a valuable source of natural antioxidants and antimicrobial agents. They also reinforce the importance of valorizing Morocco’s endemic medicinal flora in addressing contemporary biomedical challenges.

Abstract

Titanium dioxide (TiO₂) is the most extensively investigated photocatalysts, but its high band gap energy limits its photoactivity primarily to the ultraviolet region. This study presents a green approach to enhanced visible-light absorption of TiO₂ by utilizing calcined golden snail shells as a sustainable and low-cost precursor for CaO dopant. The TiO₂-CaO composites were synthesized via a simple loading technique. Characterization confirmed the successful distribution of CaO onto the TiO₂ surface, reducing in the band gap energy of TiO₂ from 3.334 eV to 3.322 eV. This modification substantially broadened the material’s light absorption into the visible spectrum. The optimized composites demonstrated feasible photocatalytic activity for the reduction of CO₂ under simulated solar irradiation with the addition of Clitoria ternatea photosensitizer, achieving initial activity higher than that of pure TiO₂. This work successfully combines the waste-derived CaO, offering a promising, environmentally friendly, and highly effective green material to improved photoresponse under visible light of TiO₂.

Abstract

The compound N-(3-aminopropyl)-2-(4-allyl-2-methoxyphenoxy)acetamide (4) was synthesized from eugenol through a three-step reaction. Possessing both amide and amine groups, the molecule provides effective hydrogen-bond donor sites suitable for anion recognition. The binding behaviour of compound 4 toward F⁻, CN⁻, AcO⁻, SO₄²⁻, and H₂PO₄⁻ was examined using 1H-NMR spectroscopy. No significant spectral changes were observed upon addition of F⁻, AcO⁻, or SO₄²⁻, indicating minimal or no interaction. In contrast, the introduction of CN⁻ and H₂PO₄⁻ produced notable chemical shift variations, consistent with hydrogen-bond formation and host-guest complexation. To further elucidate these interactions, density functional theory (DFT) calculations were performed at the aug-cc-pVDZ level. Computational models revealed that F⁻ and AcO⁻ induce cleavage of the amide N–H bond through strong hydrogen bonding and partial covalent character, whereas CN⁻ and H₂PO₄⁻ primarily engage in hydrogen-bonding interactions without bond cleavage. Gauge-independent atomic orbital (GIAO) calculations predicted substantial downfield shifts of the amide proton, from 4.72 ppm in the free receptor to 15.5, 10.89, 16.54, and 12.27 ppm for F⁻, CN⁻, AcO⁻, and H₂PO₄⁻, respectively. Overall, both experimental and computational findings demonstrate that compound 4 functions as an effective receptor for CN⁻ and H₂PO₄⁻, with strong theoretical binding responses also observed for F⁻ and AcO⁻.

Abstract

Tuberculosis (TB) remains a major global health concern, particularly in high-burden countries such as Indonesia. To better understand the transmission dynamics and evaluate intervention strategies, a compartmental SVEITR model is developed that incorporates vaccination, exposure, treatment adherence, and immunity loss. Using next-generation matrix methods, the basic reproduction number is derived and stability analysis demonstrated that the disease-free equilibrium is globally asymptotically stable when . Bifurcation analysis of the vaccine efficacy parameter revealed a forward bifurcation, indicating that TB can be eradicated once vaccine efficacy exceeds a critical threshold. Using Pontryagin's maximum principle, we developed an optimal control problem with time-dependent vaccination and treatment adherence control. Numerical simulations demonstrated that the combined implementation of vaccination and treatment adherence resulted in the greatest reduction in the exposed and infectious population. Further cost-effectiveness analysis showed that improving treatment adherence alone was the most economically efficient strategy (ACER ; ICER ), while vaccination alone was significantly less cost-effective (ACER ). Although combining vaccination with treatment adherence achieved additional health benefits, it incurs higher additional costs (ICER). These findings suggest that treatment adherence should be prioritized in resource-limited settings, with combined strategies considered when additional resources are available.

Abstract

The Calophyllum genus, part of the Calophyllaceae family, produces xanthones as dominant secondary metabolites. Calophyllum biflorum M.R. Hend. & Wyatt-Sm. is an endemic plant of Kalimantan; however, the potential of its xanthone content and biological activity has never been explored. In this study, three known prenylated xanthones: gartanin (1), ananixanthone (2), and α-mangostin (3), were isolated from C. biflorum leaves. Their chemical structures were determined by HRMS and 1D/2D NMR. The antioxidant activities of xanthones 1–3 (via DPPH radical) and their cytotoxicity toward 4T1 breast cancer cells were assessed. Xanthones 1–2 showed strong DPPH activity (IC50: 4.40 and 34.34 µM, respectively). Gartanin (1) also exhibited moderate activity against 4T1 cells (IC50 =16.70 µM). These results indicate the prenylated xanthones from C. biflorum as antioxidant agents.

Abstract

This paper presents an approximate ansatz-based solution of the cubic complex Ginzburg-Landau equation (CCGLE) influenced by electromagnetic drift and defect. This study is carried out within the area theorem framework, which describes a relation between soliton energy and duration in dissipative systems. Within this framework, a hyperbolic cosine ansatz is applied to obtain approximate expressions for the soliton energy and duration in the non-integrable dissipative system. From the derivation, the real parameter B in the ansatz is identified as a shape-controlling parameter, which results in three cases known as case I for |B|<1, case II for B > 1, and case III for B = 0. Based on these cases, front stationary solitons are obtained through the balance between the two-parameter family involving non-linearity and dispersion, as well as gain and loss, together with the interaction between drift and defect mechanisms. These interactions allow the system to self-organize into a stable localized structures within the dissipative system. Variations in the parameter B slightly change the soliton profile, especially in terms of width and amplitude. Furthermore, the drift parameter c is varied at c ϵ {-0.10, 0.60, 0.95} to investigate the behavior of the area theorem in the CCGLE, where the soliton solutions remain localized during propagation. Overall, the results indicate that the proposed approximate ansatz-based solution is able to describe localized dissipative structures in the non-integrable CCGLE with drift and defect effects.
