Synergistic effects of banana fibre and banana leaf ash on the strength and durability of eco-friendly concrete The quest for sustainable construction materials is driving the exploration of agricultural by-products as eco-friendly alternatives in concrete production. This study investigates the combined effect of banana fibre (BF) and banana leaf ash (BLA), derived from the Musa spp. plant, on the mechanical and durability performance of concrete. BFs at percentages of 0,25 %, 0,50 %, and 0,70 % were used as natural reinforcement to improve tensile characteristics. BLA, which is rich in silica and other pozzolanic compounds, was utilized as a partial cement replacement at varying percentages of 5 %, 10 %, 15 %, and 20 %. Experimental analysis included slump, compressive strength, split tensile strength, and flexural strength tests over different curing periods. An optimal combination of BF and BLA enhanced the tensile properties and improved resistance to environmental degradation without significantly compromising compressive strength. The findings suggest that incorporating banana waste derivatives enhances concrete performance and contributes to a more sustainable and circular construction economy.

An econometric analysis of Egypt’s edible oil imports in the context of the pound floatation policy Egypt is heavily dependent on imports to cover its domestic demand for oils; with imports averaging 6.58 million tons valued at approximately 82.56 billion Egyptian pounds during 2019–2023.These imports include liquid and fat vegetable oils as well as oilseeds to satisfy both household and industrial needs. The study aims to examine the key factors influencing Egypt’s oil imports, under the impact of implementing the Egyptian pound flotation policy in November 2016.The research using the simultaneous equations approach to analyze the structure of Egypt’s oil imports. Findings reveal that the contribution of both types of vegetable oils to domestic production showed a general upward trend, with statistically significant increases of approximately 4.572 and 27.517 thousand tons, a post-flotation. Contrary to expectations, imports of liquid vegetable oils increased by about 6.732 thousand metric tons, reflecting a notable growth rate between 2017 and 2023, while imports of vegetable fats declined by approximately 96.696 thousand metric tons, with an average annual decrease of 21.6%. Economic indicators further demonstrate that imports of liquid and fat oils, oilseeds, and palm oil rose by about 6.77%, 7.90%, 9.45%, and 1.8%, respectively, due to the flotation decision. However, imports of fat oils appeared largely unaffected, likely due to the substitution of these oils with lower-cost alternatives Context (archaeology) ; Tonne ; Pound (networking) ; Vegetable oil ; Econometric analysis ; Palm oil ; Economic analysis ; Edible oil Edible Oils Quality and Analysis ; Biodiesel Production and Applications ; Oil Palm Production and Sustainability

Periodic Potential for Point Defects in a 2D Hexagonal Colloidal Lattice We investigate the stochastic dynamics of point defects in a two-dimensional hexagonal colloidal crystal. Using a stochastic dynamical framework (evolution mechanics), we first extract the position-dependent drift vector and diffusion matrix from experimental trajectories, revealing dynamics that go beyond simple diffusion with constant coefficients. We then reconstruct a stochastic potential landscape by applying a periodic constraint and an equilibrium approximation within this framework. The energy differences between local minima in this landscape agree in order of magnitude with prior experimental estimates. Furthermore, analysis of the fit residuals under the equilibrium approximation provides evidence of nonequilibrium dynamics in di-vacancies. This work demonstrates how time-series analysis combined with this theoretical framework can uncover effective energy landscapes and assess detailed-balance violation in defect motion, providing a general approach for studying complex dynamics in confined systems.

Bioinformatic approach to explain how Mg from seawater may be incorporated into coral skeletons Corals have been used as geochemical proxies since the 1970s, playing a prominent role in paleoceanography. However, it has not been well elucidated how aqueous ions sourced from seawater are transported and precipitated in coral skeletons. There are limited foundational methods to differentiate and quantify biogenic and abiogenic effects during skeletal formation. Especially, Mg in coral skeletons show individual variations suggesting large biogenic effects. Here, we evaluated biological complexity by investigating how coral genes evolved over geologic time scales. We focused on Mg transporter and analysed five species from genus <i>Acropora</i> and three species from genus <i>Porites</i>. Mg transporter of <i>Acropora digitifera</i>, <i>Acropora hyacinthus</i>, <i>Acropora millepora</i> and <i>Porites australiensis</i> showed higher similarity to Mg transporter of vertebrates and were reported to appear on Earth during the Pleistocene. On the other hand, <i>Acropora palmata</i>, <i>Acropora tenui</i>s and <i>Porites astreoides</i> showed lower or no similarity to vertebrates, and they were reported to appear on Earth before the Pleistocene. We suggest such evolutional records can be evidence to demonstrate biological complexity of Mg transport from seawater. This might explain that Mg transport is subject to evolution and why Mg incorporated in coral skeletons tends to show strong biogenic effects compared with other elements.

Bayesian Optimization for Enhancing Spherical Crystallization Derived from Emulsions: A Case Study on Ibuprofen The pharmaceutical industry is a highly specialized field where strict quality control and accelerated time-to-market are essential for maintaining competitive advantage. Spherical crystallization has emerged as a promising approach in pharmaceutical manufacturing, offering significant potential to reduce equipment and operating costs, enhancing drug bioavailability, and facilitating compliance with product quality regulations. Emulsions, as an enabling technology for spherical crystallization, present unique advantages. However, the quality of spherical crystallization products derived from emulsions is significantly influenced by the intricate interactions between crystallization phenomena, formulation variables, and solution hydrodynamics. These complexities pose substantial challenges in determining optimal operational conditions to achieve the desired product characteristics. In this study, Bayesian optimization (BO) is employed to refine and optimize the operational conditions for the spherical crystallization of a representative drug, ibuprofen. The primary goal is to improve product flowability, measured by angle of repose, while maintaining the median particle size within a specified range. The optimization process focuses on key variables such as temperature, stirring speed, duration, and BSA concentration. With the help of acquisition functions, BO enables the identification of a high-quality product with fewer experimental trials compared with traditional design of experiments (DoE) methods.

Экспериментальное исследование ePTFE-трансплантата: двухосное растяжение, протокол тестирования, микроскопия Моделирование механического поведения ePTFE-трансплантатов важно для совершенствования хирургического планирования и повышения эффективности лечения в кардио- и сердечно-сосудистой хирургии. Несмотря на широкую клиническую применимость из-за биосовместимости и долговечности, понимание механических свойств этого материала по-прежнему недостаточно полно. Часто исследователи опираются на ограниченные одноосные или двухосные эксперименты, не позволяющие полностью охарактеризовать анизотропные и нелинейные аспекты деформации. В данном исследовании применяется и проанализирован двухосный испытательный протокол с широким диапазоном деформаций, разработанный для мягких тканей. Многочисленные варианты нагружения, дополненные микроструктурными данными, полученными с помощью сканирующей электронной микроскопии, позволяют сформировать более полное экспериментальное описание материала. Результаты двухосного нагружения со сложным испытательным протоколом свидетельствуют о выраженной нелинейности и направленной зависимости напряженно-деформированного отклика ePTFE-трансплантата, связанной с его микроструктурой. Полученные данные включают семь различных нагружений и сочетаются в 127 неповторяющихся комбинациях для дальнейшей идентификации параметров четырех гиперупругих определяющих соотношений, том числе структурно-мотивированных. Показано, что выбор протокола испытаний влияет на точность аппроксимации деформационного поведения трансплантата, а учет структурных особенностей материала способствует более адекватному описанию механики. Набор экспериментальных данных, включающий кривые с учетом гистерезиса и без него, а также визуализацию микроструктуры, доступен в открытом доступе. Результаты позволяют рекомендовать использование комплексных двухосных испытательных протоколов для дальнейших исследований ePTFE-трансплантатов и разработки более релевантных определяющих соотношений, учитывающих как гиперупругие, так и вязкоупругие особенности трансплантата.

Optimization of technological modes of cupola melting according to the criterion of maximum combustion temperature The object of research is the combustion temperature in the cupola furnace. The problem under study was the complexity of predicting the temperature as a function of the control parameters of the melting. In the study, the control parameters were selected as the temperature of the air heating blown into the tuyeres and the completeness of fuel combustion. Using orthogonal experimental planning, a mathematical model was constructed in the form of a second-order polynomial, which allowed to identify the patterns of influence of each control factor on the resulting value – the combustion temperature. The resulting mathematical model allowed to find out that both input variables are significant. However, if the nature of the influence of the air heating temperature on the combustion temperature is linear, then the completeness of combustion affects nonlinearly. The accuracy of the model turned out to be satisfactory, because all experimental data fell within the confidence intervals with a confidence probability of P=0.99. This allows to state the possibility of using the constructed model to predict the combustion temperature within the planning area. The ridge analysis of the response surface established that the theoretical maximum value of the combustion temperature at the boundary of the planning area is about 3000 °C. This corresponds to the values of the input variables Tair≈1120 °C and η0≈82 %. However, due to the fact that ensuring the air heating temperature at the level of 1120 °C may encounter technical complexity of implementation, the following values of the input variables can be recommended: Tair=783–1060 °C, η0=71–80. They provide combustion temperatures in the range of 2690–2980 °C, i. e. values close to the suboptimal one determined by the ridge analysis. These data allow making adjustments to the melting process, including being used for further searching for optimal melting control. The obtained solutions can be used in iron foundry shops of industrial enterprises equipped with cupola furnaces.

Thermal and Volumetric Signatures of the Mullins Effect in Carbon Black Reinforced Styrene-Butadiene Rubber Composites This paper investigates the interplay between rubber network damage, carbon black (CB) network damage, heat exchange, and voiding mechanisms in filled Styrene-butadiene rubber (SBR) under cyclic loading. To do so, three carbon black filled SBR composites, SBR5, SBR30 and SBR60 are studied. The study aims to quantify molecular damage and its role in inducing reversible or irreversible heat flow and voiding behavior to inform the design of more resilient rubber composites with improved fatigue life and thermal management capabilities. The study effectively demonstrated how increasing carbon black content, particularly in SBR60, leads to a shift from mostly reversible to irreversible and cumulative damage mechanisms during cyclic loading, as evidenced by thermal, volumetric, and electrical resistivity changes. In particular, we identify a critical mechanical energy of 7 MJ.m−3 associated with such transition. These irreversible changes are strongly linked to the damage and re-arrangement of the carbon black filler network, as well as the rubber chains network and the formation/growth of voids, while reversible mechanisms are likely related to rubber chains alignment associated with entropic elasticity.

Research on casing damage risk early warning technology based on MIT-MTT logging and 16S rRNA gene analysis With the continuous advancement of oilfield development, the number of oil-water wells experiencing casing damage due to corrosion has increased annually, which has seriously affected the injection-production balance and significantly reduced the potential for recovering residual oil. Because the water cut trends in casing-damaged wells are similar to those in water breakthrough injection wells, identifying wells with casing damage has been challenging. This study is the first to combine the Multi-Finger Imaging Tool (MIT)-Magnetic Thickness Tool (MTT) integrated logging technology with 16S rRNA gene analysis to systematically analyze the relationship between casing damage and the composition of microbial communities. The results indicated that there were significant differences in the high-corrosion zones at various depths, and the structure of the sulfate-reducing bacterial community in the produced fluids also varied. In particular, in deeper zones, the relative abundance of thermophilic bacteria, represented by Thermotogata, increased significantly. Moreover, the more severe the casing damage, the more dominant the sulfate-reducing bacteria became in the microbial community of the produced fluids. After secondary sealing treatment, the proportion of sulfate-reducing bacteria was significantly reduced. The study further found that sulfate-reducing bacteria primarily belonged to the phyla Proteobacteria, Bacillota, Thermotogata, and Thermodesulfobacteriota, while significant populations of iron-reducing bacteria were not detected in the produced fluids. This finding suggests that sulfate-reducing bacteria are the main microbial factor causing metal corrosion of the casings. Innovatively, this study proposes a biometal corrosion monitoring method for production wells based on microbial community structure, thereby providing a novel technical approach to preventing oil well corrosion.
