أثر العوامل التكنولوجية والتنظيمية والبيئية على تبني المعاملات الإلكترونية في الشركات الصغيرة والمتوسطة بليبيا – دراسة حالة مدينة رقدالين
type: item
description: This study aimed to analyze the factors influencing the adoption of electronic transactions in small and medium-sized enterprises (SMEs) in the city of Ragdalen, Libya, using the Technology–Organization–Environment (TOE) framework as a theoretical model for explaining organizational adoption of technological innovations. The importance of this study stems from the growing role of electronic transactions in enhancing organizational efficiency and improving business performance in light of the rapid global digital transformation. The study adopted a quantitative research approach by utilizing a structured questionnaire to collect data from a purposive sample of 120 owners and managers of SMEs in Ragdalen. The collected data were analyzed using SPSS software in order to test the study hypotheses related to the impact of technological, organizational, and environmental factors on the adoption of electronic transactions. The statistical analysis revealed that technological and organizational factors have a significant positive impact on the adoption of electronic transactions within SMEs, whereas the environmental factor did not show a statistically significant effect in the applied model. These findings suggest that the adoption of electronic transactions in the Libyan context is largely driven by internal organizational factors, such as managerial support and technological readiness, rather than external environmental pressures. The study concludes that the TOE framework provides a useful lens for understanding digital adoption in SMEs within developing economies; however, the influence of its dimensions may vary depending on the specific institutional and environmental context. Based on these findings, the study recommends strengthening organizational support, investing in technological infrastructure, and developing supportive governmental policies to promote digital transformation and the wider adoption of electronic transactions in the Libyan business environment.

**Research Summary: Imam al-Bukhari's Methodology in Chronological Documentation of Prophetic Biography Events
type: item
description: aims to study the precise scientific methodology employed by Imam al-Bukhari in documenting the chronological sequence of Prophetic biography events in his Sahih, stemming from the scholarly significance of his work as the most authentic compilation after the Noble Quran. The importance of this study lies in the scarcity of specialized research on the chronological aspect in al-Bukhari's work and the need to highlight his meticulous approach in historical documentation. The research is organized around three main axes: The first focuses on the historical foundation of chronological documentation through the evolution of biographical recording. The second analyzes al-Bukhari’s methodology in selecting narrators and its relationship to chronological accuracy. The third reveals the purposive dimension in his documentation by linking narrations to their historical context. The study has yielded significant results, most notably: The distinction of al-Bukhari’s methodology in chronological precision through techniques of collective chain of transmission and thematic organization, its clear purposive character, and the contribution of precise narrator selection in enhancing the credibility of historical narrations. In conclusion, the research recommends developing modern analytical tools for studying chains of transmission, expanding the research scope to include other hadith sources, and utilizing the purposive methodology in studying the Prophetic biography, aiming to develop this important scholarly field.

The Level of Libyan EFL English Teacher’s Anxiety and its Effect on their Performance
type: item
description: This study aimed to investigate the level of English language teaching anxiety among faculty members in Libyan universities (Universities of Zawia and Sabratha) and to determine its impact on their job performance. Additionally, it sought to identify differences in anxiety levels based on demographic variables, including gender, age, and years of experience. The study employed a descriptive-analytical methodology , and the research instruments were applied to a sample of (34) faculty members. The findings revealed that the overall level of teaching anxiety among the sample was generally moderate. The results also indicated a low impact of teaching anxiety on job performance , suggesting that faculty members possess a high capacity to separate psychological stressors from their professional commitments. Regarding demographic variables, statistical tests (T-test and ANOVA) demonstrated no statistically significant differences in anxiety levels attributable to gender , age , or years of experience. This reflects that teaching anxiety is a shared professional phenomenon that transcends individual and occupational backgrounds. The study recommended providing psychological support programs and training workshops to enhance coping mechanisms for the pressures of university teaching

Evidence from the 2023 Derna Floods in Libya: Institutional Capability for Disaster Response in Fragile States
type: item
description: In fragile and conflict-affected governments, where governance flaws frequently turn environmental hazards into humanitarian catastrophes, disasters increasingly test the institutional capabilities of these states. This report uses a detailed case study of the 2023 Derna floods to assess Libya's institutional readiness and response capability. Data from documentary sources and semi-structured interviews with frontline rescuers and local officials directly involved in rescue and relief efforts were gathered using a qualitative case study design. The results show that long-standing institutional flaws, such as disjointed governance, deteriorating vital infrastructure, a lack of early warning systems, and poor inter-agency coordination, greatly exacerbated the extent of the destruction in Derna. Despite these limitations, the emergency phase was significantly mitigated by strong community cohesion and outside support. The study comes to the conclusion that proactive institutional transformation, such as unified national coordinating mechanisms, infrastructure governance, responder training, and integrated early warning systems, is necessary to improve catastrophe outcomes in Libya rather than reactive crisis management.

المفاضلة الصوتية بين المخرج والسمة وأثرها في الدلالة
type: item
description: This study examines phonetic preference in Arabic through points of articulation and phonetic features and their impact on lexical and contextual meaning. It argues that variation in speech performance does not alter the overall phonological system, which remains a key reference for interpreting linguistic phenomena. The study outlines consonants and vowels and describes major features (e.g., voicing vs. devoicing, plosiveness vs. frication, elevation and emphaticness) to build criteria for phonetic strength and weakness. It then links these criteria to meaning through lexical examples showing how sound differences correlate with semantic nuance. An applied analysis of selected verses from Sūrat al-Burūj demonstrates how sound structure aligns with contextual meaning, especially in expressions of oath, grandeur, and warning. The study concludes that articulatory and feature-based patterns shape sound meaning and enhance verbal craftsmanship, supporting clearer, more effective expression.

Determinants of Economic Growth in a Resource-Dependent Economy: An Endogenous Approach to Libya (1990–2023)
type: item
description: This study investigates the primary determinants of economic growth in Libya from 1990 to 2023 through the lens of endogenous growth theory. Utilizing an Autoregressive Distributed Lag (ARDL) bounds testing approach, the research empirically evaluates the short- and long-run impacts of macroeconomic variables—including Foreign Direct Investment (FDI), inflation, government expenditure, trade openness, gross fixed capital formation (GFCF), and oil prices—on real GDP growth. The empirical findings reveal that while trade openness and oil prices exert a statistically significant positive effect on economic expansion, variables such as government expenditure, GFCF, and FDI present counterintuitive negative coefficients. These results underscore the severe structural inefficiencies, institutional deficits, and "resource curse" phenomena prevalent in the Libyan economy. The paper concludes that to achieve sustainable endogenous growth, Libya must transcend its heavy reliance on hydrocarbon revenues by improving institutional quality, redirecting public expenditure toward human capital and R&D, and creating an absorptive environment for productive capital spillovers.

The Impact of Banking Integration and Partnerships on Geopolitical Risk Management for Electronic Payment Systems: A Field Study on Libyan Commercial Banks (Al-Jumhouria Bank, Al-Sahari Bank)
type: item
description: This study aims to explore the impact of banking integration and partnership on managing the geopolitical and systemic risks of electronic payment systems, applied to the Libyan banking environment, specifically focusing on (Jumhouria Bank and Sahara Bank). The research problem crystallizes in the "interdependency dilemma" and the near-total reliance on a centralized infrastructure (the National Switch), which creates a sovereign "single point of failure". This dependency makes the payment infrastructure highly vulnerable to political conflicts, institutional divisions, and geopolitical cyber threats. The study adopted a descriptive-analytical approach, utilizing a questionnaire to collect data from a purposive sample of 40 technical and administrative staff members at Jumhouria and Sahara banks. The results revealed a significant success in achieving technical integration with the National Switch; however, this progress was not matched by a similar level of security and sovereign integration. Furthermore, the findings proved that excessive centralized reliance, in the absence of decentralized contingency plans, creates severe vulnerability to geopolitical shocks. The study recommended the necessity of transitioning to "Zero Trust" models in APIs, establishing alternative and geographically distributed sovereign data centers, and founding a unified cyber operations room to enhance operational and sovereign resilience.

Effect of Partial Replacement of Ordinary Portland Cement with Local Marble Waste Powder on the Workability and Compressive Strength of Concrete
type: item
description: The world is witnessing significant advancements in building materials technologies, particularly in the application of sustainability principles and addressing environmental challenges. These challenges include the increasing volume of construction and demolition waste currently disposed of in landfills, which is not a sustainable solution. One of the most important sustainable building materials technologies is the utilization of construction and demolition waste as a partial replacement for concrete components, resulting in economical green concrete with properties similar to the original product. One such waste material is marble waste, which requires large areas of land for disposal. Despite numerous global studies on this topic, there is limited local awareness regarding its potential use in concrete. This research aims to investigate the replacement of Portland cement with marble powder in standard 30 MPa concrete at percentages of 10%, 20%, and 30%, and to determine the impact on the concrete's fresh and hardened properties through slump and compressive strength tests. The results showed that the 28-day compressive strength is acceptable up to a 10% replacement with marble powder, achieving a compressive strength of 27.3 MPa. Replacing cement with marble powder increases the workability of concrete. Furthermore, replacing cement with a waste construction materials powder significantly reduces costs. Experiments have shown that one to two bags of cement can be reduced per cubic meter of concrete without significantly affecting its properties.

Digital Currencies and the Challenges of Issuing Them by Central Banks (A Case Study of the Central Bank of Libya)
type: item
description: This study investigates the feasibility and viability of issuing a Central Bank Digital Currency (CBDC), a "Digital Dinar," in Libya, as a potential tool to address the country's deep-rooted economic and structural challenges, primarily the persistent liquidity crisis, the prevalence of the informal economy, and low financial inclusion. The research employs an analytical methodology that combines a review of the global theoretical framework for CBDCs with an in-depth case study of Libya's financial and digital environment. A SWOT analysis was utilized to assess the project's strengths, weaknesses, opportunities, and threats, while also drawing lessons from pioneering international experiences such as Project "Aber" (Saudi Arabia & UAE) and the "eNaira" (Nigeria). The study concludes that the motivation for a Digital Dinar in Libya stems from urgent domestic necessities rather than merely following a global trend. It reveals a fundamental paradox: high public demand for digital payments coexisting with a fragile electricity and telecommunications infrastructure. The analysis indicates that the project is a "double-edged sword," offering immense opportunities but facing severe threats related to cybersecurity, a legislative vacuum, and political instability. Consequently, the study determines that a "big-bang" launch approach is unsuitable for Libya, and the optimal strategic choice is a hybrid and phased model. The study recommends the establishment of a high-level national committee, the immediate development of the legal framework, and the adoption of a gradual approach starting with a wholesale CBDC (wCBDC) pilot before moving to a retail CBDC (rCBDC). It gives the highest priority to developing offline payment solutions as a fundamental prerequisite for success.

Analyzing the relationship between body mass index (BMI) and body fat percentage and their impact on physical performance in healthy individuals
type: item
description: Body composition is an important indicator in assessing an individual's health and physical condition, as measuring body fat percentage provides more accurate information than body mass index (BMI). This study aimed to analyze the relationship between BMI and body fat percentage, on the one hand, and levels of physical performance, including cardiorespiratory fitness, muscular strength, and flexibility, on the other, in healthy individuals. The study employed a descriptive-analytical approach and included a sample of 67 male and female participants with a mean age of 20.70 ± 10.14 years. Height and weight were measured using a BMI calculator, while body fat percentage was determined using a body composition analyzer. Physical performance was assessed using tests of respiratory capacity, grip strength, leg and back muscle strength, and flexibility. The results showed a positive correlation between BMI and body fat percentage, and a negative correlation between higher body fat percentage and physical performance levels, particularly in muscular strength and cardiorespiratory fitness. The results indicate that body fat percentage is a more accurate indicator than body mass index (BMI) in explaining variations in physical performance levels. The study recommends considering body composition measurements alongside BMI when assessing individuals' fitness and health.

Tunisian-Libyan Foreign Policy After 2011
type: item
description: Tunisia and Libya remain at a crossroads. Although Libya has opened a new chapter in its transition must confront the third impossibility: securing the country from the start, unifying it, and paving the way for successful general elections. Thus, Tunisia succeeds in consolidating its democracy in a society experiencing economic, social, and political crises, The Libyan investments in the tourism sector declined by approximately 60 percent following terrorist attacks in 2015 and 2016 involving Tunisian extremists with ties to Libya. The Libyan crisis has negatively impacted the flow of foreign investment and reduced the number of tourists seeking to spend their holidays in Tunisia. According to the Barcelona Centre for International Affairs, approximately three million Tunisians depend on Libya, either through remittances from Tunisian workers or black market activities in the border region. The World Bank estimates that the Libyan crisis was responsible for 24 percent of Tunisia's economic growth slowdown between 2011 and 2015. Since then, this figure has increased significantly, amounting to approximately 2 percent of GDP annually.

Reduce Fuel Consumption in Poultry Houses by Leveraging Day-Night Temperature Variations in the MENA Region.
type: item
description: This paper presents the development of an algorithm aimed at reducing fuel consumption in poultry houses, specifically designed to leverage the significant differences in day and night temperatures in the MENA region during winter. This algorithm is a key component of a comprehensive Poultry House Management System (PHMS). The proposed algorithm adjusts heating and ventilation parameters based on real-time environmental data and bird activity levels. By exploiting natural temperature fluctuations, dynamically allowing more fresh air into the house during warm time of the day and reducing it to a minimum during cold time during the night, the algorithm demonstrated a substantial reduction in fuel usage—up to 30%—without compromising the health and productivity of the poultry, contributing to the overall efficiency of the PHMS. Additionally, increased fresh air intake helps dry litter pads and remove moisture, further enhancing the poultry house environment.

Echoes of the Scientific Efforts (Translation and Authorship) of the Libyan Historian Muhammad al-Wafi in Some Local and French Newspapers
type: item
description: This study sheds light on the impact of the scholarly efforts of the Libyan historian Muhammad al-Wafi in several local and French newspapers. These efforts include a book in French, originally a doctoral dissertation in philosophy, and translations from French into Arabic of historical books on the Islamic and modern history of Libya. Al-Wafi's interest stemmed from the importance of these sources in documenting historical facts. When a people's history is written by an author from a foreign country, which differs in ethnicity, religion, and language, the information presented requires careful scrutiny and verification by those translating it into the original language.

Intelligent Hybrid Control of Wind Energy Conversion Systems for Enhanced Stability and Efficiency
type: item
description: As wind energy becomes a bigger part of our power grid, we are running into a serious problem: wind is messy. Its unpredictable, nonlinear nature makes it incredibly difficult to keep the system stable and efficient. Old-school tools like PI and PID controllers are great for steady power, but they tend to fall apart when faced with sudden gusts or shifting weather. This study introduces a smarter way to handle that chaos using an intelligent hybrid control framework designed to keep the system steady and maximize energy capture, no matter what the wind is doing. Our approach does not just rely on one tool; it combines fuzzy logic, neural networks, and evolutionary optimization to create a system that can "think" and adapt in real-time. By mixing rule-based logic with machine learning, this hybrid setup can automatically tweak things like rotor speed and blade pitch on the fly. We have backed this up with a deep dive into the math of turbine dynamics, proving that these intelligent hybrids are far more robust and efficient than the controllers We have used for decades. Ultimately, this work offers a new blueprint for building the kind of reliable, high-tech wind systems we need for the grids of tomorrow.

Design of a simple robot for the repair process of industrial piping systems
type: item
description: The repair process of industrial piping systems is a serious problem because of its inaccessibility, unsafe conditions, and high cost of operations. The manual inspection and maintenance techniques used in the traditional processes tend to expose the workers to risks of safety and also they consume more time. This paper suggests developing a basic, inexpensive, robotic system that would be utilized specifically to examine and inspect the piping system within industrial facilities as well as carry out its simple maintenance. The suggested robotic system is aimed at mechanical simplicity, modularity, and deployment simplicity at a cost of a reasonable level of functionality and reliability. The robot can follow both straight and curved pipes, identify any surface deformities (corrosion and blockages) and provide real time visual information. The design process combines actuator selection, control architecture and mechanical modeling with components that are readily available. The proposed mechanism is experimentally validated to behave in simulated industrial conditions with a high level of accuracy. The results indicate that compared to the use of complex and expensive inspection robots, simple robots can be used to provide an effective alternative to robots to perform simple robotic tasks, especially to small and medium-sized industrial facilities. The study has a contribution to the research of industrial robotics by highlighting matters of practical design and low-cost automation of infrastructure repairs.
