The Evolution of the European Union Policies towards Israeli- Palestine Conflict: The Interplay of Regional and International Parameters
Authors: Yariş Zelal Başak , Acar Necmettin
Published: November 2024

During the 1980s, the European Community (EC) adopted a “balanced” approach to the Arab-Israeli conflict. In the 2000s, however, the EU changed its policy of neutrality. It began to address Palestinian issue within the framework of security and emphasized more and more terror dimension of the conflict. On this basis, this study aims to explore the reasons behind the changing policies of the European Union toward Israeli-Palestinian conflict. By analysing the shifts in the international and regional setting, the paper explores the securitization of the EU’s Palestinian policy since early 2000s. The findings suggest that the differing interest of member states, the failure of the EU’s liberal regional approach in the Middle East, and the changing geostrategic setting are the key factors driving the EU’s evolving policies on the Arab-Israeli conflict.
Investigation of impact of Calotropis procera extract for properties of mild steel in acidic mediums
Authors: Khedim Fatima Zahra , Meliani Mohammed Hadj , Amara Mouna , Lamsadfa Sidamar , Chérifi Chérifa
Published: November 2024

Mild steel, widely used in gas and oil pipelines, is recognized for its remarkable capacity to absorb both internal and external energy, as well as its high tensile strength. Despite these attributes, the constant exposure to corrosive toxic substances within these pipelines poses a significant challenge. Over time, corrosion weakens the steel’s resilience to impact and increases the likelihood of failure or explosion due to the buildup of fluid pressure. To mitigate this issue, we explored an eco-friendly approach by introducing natural, non-toxic additives derived from the plant Calotropis procera (CP). The goal was to restore some of the steel's lost energy absorption capacity and enhance its resistance to corrosion and fracture.To test the effectiveness of Calotropis procera extract, we conducted weight-loss experiments using API 5L X70 steel in a solution containing 1 mol sulfuric acid and oil. We varied the concentration of CP plant extract in the solution, using 5%, 7%, 10%, and 13% to evaluate its corrosion inhibition properties. Surface examination was carried out using optical microscopy, which confirmed a corrosion inhibition rate of 50% in the CP + H₂SO₄ solution. To further investigate the mechanical performance, we performed Charpy impact tests in the same acidic environment with CP concentrations of 5%, 7%, and 10%. The results revealed that at a 10% concentration of plant extract, the steel exhibited an absorbed impact energy of 278 J, with a corresponding resilience value of 348.325 J/cm². These findings demonstrate the potential of Calotropis procera extract as an effective, sustainable solution for improving the durability of steel used in corrosive environments.

Authors: Ferhati Ahmed , Belazreg Nour El Houda , Khodja Hakim Djafer , Mitiche-Kettab Ratiba
Published: November 2024

Groundwater modeling using MODFLOW and GIS tools is crucial for understanding the complexities of groundwater dynamics in Algeria's semi-arid and arid climates. This study focuses on the quantitative assessment of the phreatic aquifer within the Hodna aquifer system over the period of 1973-2005. The study employs MODFLOW and GIS tools to model groundwater flow. Calibration and validation processes, using a trial and error technique, refine the models to understand water table behaviors and drawdown within the Hodna basin. Calibration efforts yield insights into groundwater dynamics, particularly significant drawdowns observed in cities like M’sila and Boussaada. Parameters such as hydraulic heads, piezometric levels, drainage, and hydraulic conductivity values are extracted from MODFLOW simulations. Analysis reveals a decline in groundwater volume and consistent drops in borehole water levels over the past 32 years, highlighting the challenges of comprehending recharge resources and the impact of groundwater depletion in the region. The study underscores the importance of calibrated groundwater models in managing and mitigating groundwater depletion in Algeria's Hodna basin. It elucidates predominant groundwater flow patterns towards Chott and emphasizes the need for comprehensive understanding and management strategies to sustainably manage groundwater resources in semi-arid and arid regions.
A contribution to the study of phosphate’s effects on calcareous soils to be stabilized with lime and natural pozzolana
Authors: Oussama Ali Bachir , Omar Boudlal , Mohammed Khattaoui
Published: November 2024

When investigating the potential use of lime and natural pozzolana for subgrade soils containing phosphate, especially on agricultural lands, the effectiveness of these traditional binders needs to be assessed because of the possible deleterious effect of phosphates anions. This paper addresses this question using the problematic marly soil of Medea which was deliberately contaminated with a common fertilizer mono ammonium phosphate (0, 2, 4 and 6% by dry weight) and then stabilized with lime and/or natural pozzolana (0, 8%),(0, 20%) by dry weight respectively. Micro and macrostructural changes of these mixtures were studied under X-Ray diffraction test and Scanning electron microscope imaging. Variations of pH levels on a 90 days period, Atterberg limits between 1 to 30 days of curing, normal Proctor parameters, immediate bearing index at optimum moisture were also carried out. Overall, the results indicate that the uncontaminated marly clay soil wasn’t very reactive to lime stabilization even with 8% lime and it required the addition of natural pozzolana with lime to exhibit some improvements. Aside from that, phosphates proved to be deleterious for stabilizing marly clay of Medea producing considerable impact on all the results. It was also shown that calcite present in the soil can interfere with the employed stabilization technique.

Published: November 2024

Over the past two and a half decades, electric vehicles (EVs) have attained a magnificent market, and the day by day it is increasing throughout the world. It is also one of the hopeful remedies for the greenhouse gases. But the main difficulty is the charging of the battaries. To charge an electric vehicle takes a long time period, and it is also not safe because they use lithium-ion batteries to run them. Lithium-ion batteries require 5 to 6 hours for their charging, and the battery banks are bulky as well as heavier and are not fireproof. The lifespan of lithium-ion batteries is also too short; they last for less than 3 years. By using the supercharging capacitor instead of lithium-ion batteries in electric vehicles, the above-mentioned restrictions can be overcome easily. Super-capacitor modules can provide the high current and high acceleration while the vehicle is starting, as well as they are very hopeful to increase the life of batteries. The design of this project includes a charger and battery technology that is fast in charging, fireproof, and long-lasting. This charging system has high-amps-supported electronic circuits and electronic components used for charging of 2.7 V and 1000 F (500 F x 2 Nos.) capacitors.

This project is concerned with the methods of changing plastic waste to fuel known as pyrolysis which is thermal degradation of materials in an atmosphere devoid of oxygen. This is accomplished by applying tremendous heat to the plastic causing degradation into smaller hydrocarbon products which include liquid fuel, gas and char residue among other things. The liquid fuel can be upgraded further to produce various useful hydrocarbons such as diesel and gasoline, and the gases may be used as a means of recovering energy. This project aims to show how plastic waste which is usually a problem can be turned into a useful source of fuel to cut down waste and improve energy practices. This project can be described as an important strategy in addressing two key problems of global significance: management of plastic waste and sustainable energy generation. With the increase of global plastic pollution and fossil fuels waning, there is an urgency in coming up with new strategies to resolve these environmental dilemmas. Such a solution includes the process of changing plastic waste into diesel fuel which not only reduces plastic waste but also enables the harnessing of an energy source.
Technology-Based Interventions for Autism Spectrum Disorder: A Systematic Review
Authors: Sumra Rehmat , Sumra Dr. Bushra
Published: November 2024

Introduction: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and repetitive behaviors. Its prevalence has steadily increased, with the CDC reporting a rise from 1 in 100 children in 2006 to 1 in 44 in the United States by 2021. ASD manifests in a spectrum of symptoms, requiring tailored interventions to address each child's unique needs. Recent advancements in technology have shown promise in aiding children with ASD, particularly through robotics and socially assistive robots (SARs). This systematic review explores the impact of technology-based interventions on children with ASD, assessing their efficacy in enhancing social skills, communication, and behavior regulation. Methodology: This review followed PRISMA guidelines, screening 46,580 articles across databases such as PubMed, Cochrane, Science Direct, Google Scholar, and PsychInfo. After applying inclusion and exclusion criteria, 254 studies were selected for in-depth review. The review focused on technology-based interventions, including robotics and socially assistive robots, with MeSH terms such as "Technology," "Artificial Intelligence," "Autism Spectrum Disorder," and "ASD." Results: Technology-based interventions, particularly SARs, demonstrated significant improvements in social interaction, emotional regulation, and communication for children with ASD. Robots such as LEGO Mindstorms and "Kaspar" were effective in enhancing eye contact, cooperation, and emotional recognition. However, results varied depending on the type of technology used, study design, and participant characteristics. Conclusion: While technology-based interventions hold promise for children with ASD, further research is needed to standardize intervention protocols, dosage, and long-term outcomes. These tools offer a non-invasive, scalable solution for enhancing social and cognitive skills, but variability in study designs limits definitive conclusions.

The short-term aging effects of Polyvinyl Chloride (PVC) and Nano Silica (NS) as modifiers on asphalt binders
Authors: Nguyen Hoang Phong
Published: November 2024

Many studies have shown that for a pavement paved with an asphalt-aggregate mixture, to achieve its design life, the asphalt mustn’t age too hard during storage, during the production process, or while on the road. The short-term aging effects of Polyvinyl Chloride (PVC) and Nano silica (NS) as modifiers on asphalt binders were investigated. The physical properties, penetration, softening points, viscosity measurements, dynamic shear rheometer (DSR), and multiple stress creep recovery (MSCR), under the aging conditions of unmodified and modified asphalt were determined for various PVC and NS contents. To simulate the aging in a short term in the laboratory, the rolling thin film oven test was conducted. Obtained results indicated that adding 5% PVC and 1% NS had a significant positive effect on the aging resistance of asphalt binder through increasing 59.49% penetration aging ratio (PAR) values. It was also observed that adding PVC and NS reinforced the aging resistance of the asphalt binder. Nevertheless, adding PVC and NS reduced softening point increment (SPI), viscosity aging index (VAI), as well as rutting factor aging index (AIR). The asphalt binder modified with PVC/NS demonstrated better performance compared to the asphalt binders only modified with PVC or NS. The results of this study demontrate the feasibility of applying the PVC/NS combination treatment to asphalt in practical applications.

Published: November 2024

Eine intakte Biodiversität ist unerlässlich für das Leben auf der Erde und das menschliche Wohl. Sie erhöht die Funktionalität und Stabilität von Ökosystemen, was besonders in Zeiten von Umweltveränderungen wie dem Klimawandel wichtig ist. Der aktuelle Verlust an Biodiversität, der in nahezu allen Organismengruppen zu beobachten ist, stellt ein erhebliches Risiko dar. Er gefährdet nicht nur das Funktionieren der Ökosysteme, sondern auch deren Anpassungsfähigkeit an zukünftige Veränderungen. Angesichts globaler und lokaler Herausforderungen ist es dringend notwendig, Biodiversität zu schützen, um die Stabilität von Ökosystemen und das Wohl der Menschen langfristig zu sichern. Im Kanton Graubünden wurde deshalb eine Biodiversitätsstrategie entwickelt und Massnahmen beschlossen, um unser Naturkapital langfristig zu erhalten.

This paper presents the results of a study of the qualitative parameters of the coating of the polymer-powder composition of coniferous wood, depending on the modes of heat treatment during its production. The quality of the polymer coating was assessed by abrasion, lattice incision and pencil hardness methods. To obtain coatings, an epoxy-polyester composition applied to wood by spraying followed by curing during heat treatment was used. The temperature of the heat treatment varied in the range of 80-120 ° C with an exposure time of 5-20 minutes. The intervals of thermal effects were chosen based on the analysis of domestic and international research experience in this area. The influence of the curing time and temperature of the polymer-powder coating on the following parameters of the material surface is shown: wear resistance, water absorption, adhesion, hardness. It was found that the wood coating based on an epoxy-polyester powder composition, treated at a temperature of 90 ° C for 15 minutes, has the highest quality technological and operational parameters. An increase in temperature and processing time has a negative effect on the quality of the coating due to the release of resins from the wood. This is especially noticeable at a curing temperature of 120 °C, when the process of resin extraction from coniferous wood increases. The results obtained make it possible to optimize the process of processing wood using polymer-powder coatings to achieve maximum protection and decorative characteristics with simultaneous drying or thermal exposure. Based on a comparative analysis with the literature data, it is shown that the technological modes of processing polymer powder paint significantly depend on the type of wood.
