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.

Electronic management is considered as one of the basic components of the information system, and one of the means that has caused a great stir in our present era, as the need for it has become very urgent and necessary in various fields and sectors, especially in the management of the education sector, as it represents one of the quality standards (the use of technical means in the institution educational), therefore, the aim of this research is to closely identify its concept and explain its importance in the success of managing educational institutions in all their administrative, educational and office aspects. In this research, some basics were presented as an introduction to the topic under study to ensure clear understanding. The research also pointed out some of the challenges and obstacles facing the application of electronic management and proposed solutions to overcome these obstacles.   The researchers used the descriptive approach to suit the research objective. Various sources were reviewed, including research articles, books, and reports

This Paper investigates the problem that EFL learners of First Year in English Department at Alassaba College commonly come across issues when pronouncing the th sounds /θ/ and / ð /.It is reported that they frequently substitutes /th/ for the voiceless sound /θ/ and /θ/ for the voiced sound / ð /. Researchers believe that learning the differences between these sounds can help the students of Arabic to be able to pronounce English consonants properly. This is due to the fact that first language can affect learning the second language. Whenever the differences are identified it will be easy for students to learn. The purpose of this study is to explore the interference of mother tongue in pronunciation field that was made by learners of English Department dealing with English sounds/θ/ and / ð. The participants were 30 EFL learners with Arabic background as their mother tongue. To help students overcome their difficulties, comprehensively instructingthe way to pronounce /θ/ and / ð / sounds correctly, using minimal pairs with numerous examples, and creating an inspired learning environment for the students to practice pronunciation are recommended, and recording the students’ pronunciation and analyzed using contrastive analysis.
