This study explores how private institutes in the Jazan Region of Saudi Arabia managed service quality of online training during the COVID-19 pandemic. The study, conducted using semi-structured interviews with key personnel from four institutes, found that online training was critical during the pandemic. However, the study identified challenges associated with online training, including in technology, communication, and students’ motivation . The study recommends effective planning, communication, and technology infrastructure to support online training and deliver high-quality service. The findings contribute to the literature on the impact of COVID-19 on service quality and highlight the potential of online training as an educational tool in the face of challenges. |

Abstract

The indoor environment affects the quality of life, well-being, and productivity. Indoor occupants are affected by multiple factors such as heat, acoustics, lighting, and electromagnetic radiation. Therefore, cement mixed with basalt rocks was prepared and the effect of electromagnetic radiation on it was studied. It was clear from the results that cement mixed with basalt rocks is good at mitigating radiation and absorbing heat from the internal environment. Therefore, it is possible to use cement mixed with basalt as an internal cladding material to protect against the danger of radiation in enclosed spaces. |

Abstract

|
|
|
A nanometric buried layer of iron disilicide was synthesized by ion implantation in Si(1 1 1) p-type at different temperatures using 195 keV Fe ions with a dose of 2.1017 Fe+/cm2. The investigation of the phase composition is carried out by Rutherford backscattering spectrometry (RBS), whereas the structural characterization is obtained by X-ray diffraction (XRD) pole figure. The process of the silicidation has been investigated at a function of the ion implantation temperatures ranging from 200 to 440 °C. The precipitates favor epitaxial growth with respect to Si(1 1 1) planes with epitaxial relationships -FeSi2(2 2 0) //Si(1 1 1) and/or -FeSi2 (2 0 2) // Si(1 1 1). |
