Abstract Formulating oil-based drilling fluids (OBDFs) with an ultra-low oil-to-water ratio (OWR ≤ 60:40) presents a formidable stability challenge due to the maximized interfacial area and intensified stress on the interfacial film under high-temperature, high-density conditions. To address this, we engineered a synergistic stabilization system through molecular and colloidal design. A novel hyperbranched polyamide emulsifier (epoxidized soybean oil polyamide) (ESOP), synthesized from epoxidized soybean oil, exhibits superior thermal stability and interfacial activity due to its hyperbranched architecture. Combined with calcium petroleum sulfonate (CPS) and hydrophobic nanosilica (HNs), it enables a high-performance OBDF with an ultra-low OWR… More >

Abstract Slug flow represents one of the most critical and operationally challenging regimes in oil-gas-water multiphase pipelines. To advance both mechanistic understanding and predictive capability, this study integrates physical analysis with data-driven modeling to elucidate the conditions governing slug formation and to enable its rapid and accurate prediction. A systematic review of existing research is first undertaken to clarify the mechanisms responsible for slug initiation. The influences of gas superficial velocity, liquid velocity, liquid viscosity, liquid surface tension, and the axial component of gravity are examined to characterize their roles in interfacial instability and flow transition.… More >

Abstract Accurate soil classification is essential for pavement design; however, the traditional American Association of State Highway and Transportation Officials (AASHTO) classification system relies on extensive laboratory testing and subjective judgment. This study presents an artificial intelligence (AI) enhanced framework for AASHTO soil classification. A synthetic dataset of 349,015 samples was generated using parameter ranges for five AASHTO input variables to support model development. Four machine learning models were trained, analyzed, and compared where the random forest (RF) consistently achieved the highest accuracy of 100% among the four models in predicting AASHTO soil groups.

Abstract Separation bubbles forming on airfoils significantly influence aerodynamic behavior, particularly at low Reynolds numbers, making their accurate prediction a critical challenge in transition modelling. This study investigates numerical modeling of a separation bubble and the effects of airfoil thickness and camber variation on the formation of the bubble dynamics at low Reynolds numbers. The numerical results were compared with the experimental results obtained from surface pressure distribution measurements, oil flow visualisation, and surface shear measurements to analyse the detailed flow behavior. The combination of pressure and flow visualisation techniques provided complementary insights, enabling a detailed… More >

Abstract Slope failures, particularly in railway embankments during intense rainfall, are a major cause of economic damage and humanitarian loss. To forecast how shear cracks develop in slopes under heavy precipitation, we present a novel modeling framework: the Extended Cohesive Damage Element enhanced by soil moisture (SMECDE). The method first translates forecasted rainfall into soil moisture levels via an established correspondence. Then, recognizing that rainfall infiltration lowers soil cohesion—particularly at varying depths—we introduce a Soil Moisture Decoherence Model (SMDM) based on experimental data, which quantifies how cohesion degrades with moisture and how depth affects this process.

Abstract Citrus is a genus of great economic importance and a complex history of hybridization. The aim of this work is to present the trajectory of essential oil (EO) from the citrus fruit peel to their main uses. The flavedo is a morpho-functional region of the citrus fruit peel where EO-producing cavity glands are located. The EO produced is the source of the characteristic citrus aroma relevant for flavor (food and beverage industry) and fragrance applications (perfumery). The citrus EO is dominated by monoterpene hydrocarbons. Out of these, D-limonene is the major compound in the peel EO… More >

Abstract This study investigated the association between floral and fruiting traits in oil tree peony to inform elite breeding and hybrid programmes. Floral and fruiting metrics of Paeonia ostii ‘Fengdanbai’ and Paeonia rockii ‘Zibanbai’ were recorded under natural conditions; data were analysed using independent-samples t-tests, Pearson correlations, stepwise multiple linear regression and membership functions. Paeonia ostii ‘Fengdanbai’ produced more pollen number per flower, but fewer ovules and seeds per fruit than Paeonia rockii ‘Zibanbai’ (p < 0.05). Pollen viability and stigma receptivity followed similar unimodal temporal curves in both taxa. Peak pollen viability occurred on day 3 after anthesis in P. ostii… More >

Abstract Soybean oil is one of the most widely consumed vegetable oils globally, valued not only for its affordability and functional properties but also for its rich profile of bioactive compounds. This review critically synthesizes current knowledge on the non-volatile bioactive constituents of crude and refined soybean oil, particularly polyunsaturated fatty acids, tocopherols, phytosterols, phospholipids, and saponins, as well as volatile bioactives present in soybean essential oil. Emphasis is placed on their antioxidant, anti-inflammatory, cardioprotective, metabolic, antimicrobial, and dermatological activities, alongside their relevance for functional foods, nutraceuticals, cosmeceuticals, and pharmaceutical applications. The review examines how oil… More >

Abstract Global climate change has intensified drought and soil salinization, posing serious threats to crop productivity and ecosystem stability. Traditional physical and chemical reclamation methods are often expensive, energy-intensive, and unsustainable. In contrast, halotolerant plant growth-promoting rhizobacteria (HT-PGPR) have emerged as a promising, eco-friendly strategy to address extreme climate change-induced land salinization. HT-PGPR enhance plant tolerance by regulating osmotic balance, ion homeostasis, antioxidant defense, and phytohormone signaling. Current evidence for these effects is largely based on greenhouse pot and microcosm studies, while their validation in field experiments remain limited. In addition, HT-PGPR can improve nutrient availability… More >

Abstract Re-fracturing horizontal wells is a critical strategy for enhancing recovery from tight oil reservoirs, but its success depends on the evaluation of candidate wells and locations. This process is complicated by production-induced alterations in reservoir pressure and geomechanical responses. This study introduces a workflow to evaluate re-fracturing potential by integrating coupled fluid flow and geomechanical modeling for the production of initial hydraulic fractures. We developed a numerical model that simulates the poroelastic response of a tight oil reservoir to depletion from an initial set of hydraulic fractures. To quantify the re-fracturing potential along the horizontal… More >
