This study investigates whether internal auditors in Libyan oil companies possess the necessary competence and capabilities in the security of electronic accounting information systems within an era of transition from manual auditing to electronic accounting information system auditing. The study also examines the issue of whether internal auditors implement sufficient safeguards to address the risks associated with electronic accounting information systems. A questionnaire survey adopted for data collection revealed that: internal auditors in the sampled companies possess a high level of competence and efficiency in electronic accounting information system security; and that they also follow all protective measures to counter the risks of electronic accounting information systems. However, descriptive statistics show that the mean scores of participants' responses regarding the competence and efficiency of internal auditors in electronic accounting information system security were lower than the overall mean of the axis. This could be seen as a deficiency on the part of internal auditors in reviewing risks related to electronic accounting information systems, monitoring management's implementation of regular maintenance of electronic systems, ensuring the existence of sufficient protection programs to scan electronic programs or magnetic disks, implementing procedures to limit risks arising from electronic equipment damage, and periodically evaluating information security applications within the company. Descriptive statistics also indicate that the average scores of participants' responses regarding internal auditors' adherence to all protective measures to counter the risks of electronic accounting information systems were lower than the overall mean of the axis. This could be seen as a deficiency on the part of internal auditors in monitoring IT staff in implementing required security measures, participating in updating security methods according to changes in the evolving IT environment, participating in developing specific security policies such as selecting the appropriate technology and its effectiveness, participating in developing and formulating a strategy for developing the security of electronic accounting information systems, and contributing to the detection of security breaches through reports and describing the type of breach

Vortex airflow-assisted melt differential electrospinning for preparing superfine fiber yarns was proposed. This method with solvent-free exhibits a higher yield of 20 ± 5.17 m/min compared to the range of 0–5 m/min achieved by solution electrospinning with organic solvents. Simulation and high-speed photography show that the fibers are aggregated by suction airflow and twisted into yarns by vortex airflow. Polylactic acid (PLA) superfine fiber yarns exhibit fine fiber diameters ranging from 0.96 to 5.57 μm, a yarn diameter of 211.7 ± 40.8 μm, and a high tensile strength of 39.4 ± 3.12 MPa. Furthermore, these PLA melt electrospun yarns can be woven into fabric with a water contact angle of 120.1° and triboelectric voltage of 7.41 V, demonstrating their potential in self-cleaning textiles and flexible smart textiles. Moreover, this method is generally applicable to thermoplastic polymers including polyethylene …

A design of a geothermal heat pump heating, ventilating, and air conditioning system has been done for XYZ Indianapolis School by using renewable energy. Geothermal energy is one of the important energies that has proved itself in air conditioning systems all over the world. The design was classified in three points as follows. Using borehole heat exchanger (BHEs) vertical type, heat pump and all its equipment such as mechanical room, pipes, and fitting design to cover the total load of the school the results were 20 boreholes and a total flow rate of 60 gpm (3 gpm/bore) of 20 % propylene solution, and spacing 20 ft with 1.1 Hp and 6.5 in impeller size. For individual borehole design, the results were 15 boreholes and a total power consumption 1.1 kW. For the ventilation design, the peak load for heating is 42779 Btu/hr, and for cooling, it is 47779 Btu/hr. There are 4 boreholes, a 0.5 hp electric pump with a flow rate of 10 gpm a 40ft of H2O pressure drop, and a 10 hp fan integrated with a water-to-water heat pump. The total load we assumed for the heating supply in class 6 and the corridor are 10% and 25 %, respectively. The thermal resistance was calculated for each case according to the fluid flow rate. The ventilation load of the school is designed separately from the heating and cooling loads and connected to a water-water heat pump that will make the system work with high efficiency. Finally, we designed this project using Geothermal Energy, which is cleaner than conventional energy.

Abstract

This research explores Libyan university students' perceptions of the use of podcasts and audio books as tools for learning English as a Foreign Language (EFL). Employing a quantitative research method, data were collected online through questionnaires distributed to third-year students of English in three Libyan Universities. The study involved a sample of 76 students and aimed to evaluate the effectiveness, flexibility, and motivational factors associated with these audio tools.

The results indicated that podcasts and audiobooks significantly enhance EFL learners' speaking skills, familiarize them with the cultural and social contexts of the English language, and encourage continuous learning outside the classroom. A substantial majority of participants found these tools easy to navigate and valued their free accessibility. Additionally, the flexibility of being able to listen at their convenience was highly appreciated, supporting learner autonomy and engagement.

The study's findings underscore the potential of integrating podcasts and audiobooks into the EFL curriculum, highlighting their role in fostering independent learning and improving overall language proficiency. The research offers valuable insights for EFL instructors and curriculum developers, recommending the inclusion of these tools as part of the formal education syllabus to enhance the language learning experience.

A new record for Leptadenia arborea (Forssk.) Schweinf. is reported for the first time in the flora of Libya. This species was collected from Ariggiba region (110 km southwest Sabha city). A full description and habitat information on the plant are provided. A brief discussion about the most important traits of this species is presented.
