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 business plan which is a formal writing and statement that describing new or existing business goals always helps organizations or investor to set the task that need to be performed in order to invest properly by potential investors to the entrepreneurs. It helps businesses who are seeking investment and convey their business visions to potential investors and customers. Further, it can be also used to attract employees and supplier in order to simply understand how the company in future can be managed efficiently. Simply a business plan covers all important set goals, mission, vision, and all the strategies that a company will use to meet them and if potential problem that may confront the business and the ways to handle them. The purpose of this research is to provide enough resources for business plan to develop a web store using e-commerce technology by using SellerDeck software solution and making a competing company where customer can easily purchase their favourite brand of mobile phones, tablet computers and its accessories. At the end of this research the results is that the ecommerce technology will increase all over the world because of making it easier for the enterprise business and customers for shopping information and view the contents of web store products and payment system.

Abstract

Makrofol-DE 1-1 CC Polycarbonate is a class of polymeric solid state nuclear track detector which has many applications in various radiation detection fields.

Structural property studies using X-ray diffraction were performed on the non-irradiated and irradiated Makrofol samples. The intensities of the characteristic absorption bands were found to decrease predominantly with increasing the proton fluence in the ranges 0-5x10¹¹ ions/cm² indicating that the degradation is the dominant mechanism.

Non isothermal studies were carried out using thermo-gravimetric analysis (TGA) and differential thermo-gravimetric (DTG) to obtain information concerning the thermal stability for Makrofol detector. The obtained TGA thermograms indicated that the Makrofol detector decomposes in one main weight loss stage.

Using the TGA curves, both the onset temperature of decomposition and the activation energy of thermal decomposition were calculated. The results indicated that the proton irradiation of Makrofol detector in the fluence range 0-5x10¹¹ ions/cm² causes an initial scission that reduces the thermal stability of the Makrofol samples. The proton irradiation in the fluence range 5x10¹¹-1x10¹⁵ ions/cm² led to a more compact structure of Makrofol polymer, which resulted in an improvement in its thermal stability with an increase in the activation energy of thermal decomposition.
