Abstract In modern engineering, enhancing boiling heat transfer efficiency is crucial for optimizing energy use and several industrial processes involving different types of materials. This study explores the enhancement of pool boiling heat transfer potentially induced by combining perforated copper particles on a heated surface with a sodium dodecyl sulfate (SDS) surfactant in saturated deionized water. Experiments were conducted at standard atmospheric pressure, with heat flux ranging from 20 to 100 kW/m². The heating surface, positioned below the layer of freely moving copper beads, allowed the particle layer to shift due to liquid convection and steam More > Graphic Abstract

Abstract Tight oil reservoirs face significant challenges, including rapid production decline, low recovery rates, and a lack of effective energy replenishment methods. In this study, a novel development model is proposed, based on inter-fracture injection following volumetric fracturing and relying on a high-temperature and high-pressure large-scale physical simulation system. Additionally, the CMG (Computer Modelling Group Ltd., Calgary City, Canada) software is also used to elucidate the impact of various single factors on the production of horizontal wells while filtering out the interference of others. The effects of fracture spacing, fracture half-length, and the injection-production ratio are… More >

Abstract Objectives: Among cutaneous malignancies, melanoma stands out for its particularly aggressive nature, with therapeutic interventions becoming notably limited once the disease progresses. In this research, we investigate the tumor-suppressing capabilities of water-extracted Korean mistletoe (Viscum album var. coloratum) and its purified lectin component (V. album var. coloratum agglutinin, VCA) using two distinct mouse melanoma models: B16BL6 and B16F10 cell lines. Methods: The impact of water extract and VCA treatments on melanoma cells was assessed through multiple experimental approaches, examining cellular survival rates, programmed cell death pathways, multicaspase activity, and cell cycle distribution patterns. To elucidate the interconnections among… More >

Abstract The experimental analysis takes too much time-consuming process and requires considerable effort, while, the Artificial Neural Network (ANN) algorithms are simple, affordable, and fast, and they allow us to make a relevant analysis in establishing an appropriate relationship between the input and output parameters. This paper deals with the use of back-propagation ANN algorithms for the experimental data of heat transfer coefficient, Nusselt number, and friction factor of water-based Fe₃O₄-TiO₂ magnetic hybrid nanofluids in a mini heat sink under magnetic fields. The data considered for the ANN network is at different Reynolds numbers (239 to 1874),… More >

Abstract Agriculture is a primary activity in many countries, with wheat being a major cereal crop in India. Accurate pre-harvest forecasts of crop acreage and production are critical for policymakers to address supply-demand dynamics, pricing, and trade. This study focuses on estimating wheat acreage and yield in Barwala block, Hisar district, Haryana, for the 2019–2020 Rabi season using remote sensing techniques. Multi-temporal satellite data capturing phenological stages of wheat (Seedling to Ripening) were processed using supervised classification with a maximum likelihood classifier in ERDAS Imagine. Wheat crop acreage was determined by overlaying ground truth points on… More >

Abstract The effect of using 2% and 10% sodium hydroxide solution as surface treatment of rape straw on its water vapor adsorption properties is analyzed in the relative humidity (RH) range of 0% to 98%. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and Fourier-transform infrared spectroscopy (FTIR) are used to investigate the morphological, chemical and structural changes of the treated straw surface. The mineral particles formed on the surface after the treatment are analyzed using X-ray diffraction (XRD). The application of sodium hydroxide solution results in the disruption of the straw surface. As the concentration More > Graphic Abstract

Abstract The extensive use of polymeric materials in single-use packaging has driven the need to develop biodegradable alternatives. This study investigates the incorporation of graphene oxide (GO) and Moringa oleifera seed oil (MOSO) into a gelatin matrix to create polymer films and evaluate their potential as active packaging materials. The properties of these films were evaluated using structural, thermal, mechanical, optical, and physicochemical methods to determine their suitability for food packaging applications. The results showed that GO and MOSO were homogeneously dispersed in the gelatin matrix, forming colloidal particles (around 5 µm in diameter). The addition… More > Graphic Abstract

Abstract This research investigates the design and optimization of a photovoltaic (PV) water pumping system to address seasonal water demands across five locations with varying elevation heads. The system draws water from a deep well with a static water level of 30 m and a dynamic level of 50 m, serving agricultural and livestock needs. The objective of this study is to accurately size a PV system that balances energy generation and demand while minimizing grid dependency. Meanwhile, the study presents a comprehensive methodology to calculate flow rates, pumping power, daily energy consumption, and system capacity.… More >

Abstract Accurate estimation of evapotranspiration (ET) is crucial for efficient water resource management, particularly in the face of climate change and increasing water scarcity. This study performs a bibliometric analysis of 352 articles and a systematic review of 35 peer-reviewed papers, selected according to PRISMA guidelines, to evaluate the performance of Hybrid Artificial Neural Networks (HANNs) in ET estimation. The findings demonstrate that HANNs, particularly those combining Multilayer Perceptrons (MLPs), Recurrent Neural Networks (RNNs), and Convolutional Neural Networks (CNNs), are highly effective in capturing the complex nonlinear relationships and temporal dependencies characteristic of hydrological processes.

Abstract Watermarking is embedding visible or invisible data within media to verify its authenticity or protect copyright. The watermark is embedded in significant spatial or frequency features of the media to make it more resistant to intentional or unintentional modification. Some of these features are important perceptual features according to the human visual system (HVS), which means that the embedded watermark should be imperceptible in these features. Therefore, both the designers of watermarking algorithms and potential attackers must consider these perceptual features when carrying out their actions. The two roles will be considered in this paper… More >
