Some new norms need to be adapted due to COVID-19 pandemic period where people need to wear masks, wash their hands frequently, maintain social distancing, and avoid going out unless necessary. Therefore, educational institutions were closed to minimize the spread of COVID-19. As a result of this, online education was adapted to substitute face-to-face learning. Therefore, this study aimed to assess the Malaysian university students’ adaptation to the new norms, knowledge and practices toward COVID-19, besides, their attitudes toward online learning. A convenient sampling technique was used to recruit 500 Malaysian university students from January to February 2021 through social media. For data collection, all students were asked to fill in a questionnaire that was developed based on previous literature, using Google Forms. 498 students completed the questionnaire (response rate 99.6%). Malaysian Ministry of Health was the main source (83.73%) that students refer to when looking for information on COVID-19. Only 40% of the participants had good overall knowledge about COVID-19; such knowledge was influenced by the students' field of study. The current practice towards COVID-19 was good only by 26.1% of participating students; such practice was influenced by the ethnic groups. Additionally, 60% of participated students agreed that COVID-19 can be successfully controlled. About one-third of participants had positive attitudes toward online learning. The major challenges facing students during online learning include distraction of the learning environment (80%), unstable internet connectivity (75%), lack of motivation (70%), limited technical skills (41%), and limited broadband data (34%). In conclusion, the knowledge and practice toward COVID-19 was good in less than half of Malaysian university students. Attitudes to the controlling of COVID-19 were positive, while the attitudes toward online learning were neutral among most of the Malaysian university students. Challenges toward online learning are diverse and include both technical and student-related problems.
The aim of the present work is concerned with the effect of ?-irradiation on PM-355 with absorbed dose of (30-160Mrad) range. This polymer is evaluated spectrophotometrically for use as high dose dosimeters. The absorption spectra of irradiated samples showed radiation induced absorption changes. There is an increment in absorption proportional with absorbed dose. This increment is attributed to interfaces traps which, are formed by irradiation. Calibration curve was drawn .The linear relation was found in calibration curve, and dosimeter range was determined from the linear part. The linearity in response curve suggested that PM-355 could be used as dosimeter within (30-160Mrad) rang. Energy gap shift was used as a second tool to determin
... Show MoreThis is a survey study that presents recent researches concerning factional controllers. It presents several types of fractional order controllers, which are extensions to their integer order counterparts. The fractional order PID controller has a dominant importance, so thirty-one paper are presented for this controller. The remaining types of controllers are presented according to the number of papers that handle them; they are fractional order sliding mode controller (nine papers), fuzzy fractional order sliding mode controller (five papers), fractional order lag-lead compensator (three papers), fractional order state feedback controller (three papers), fractional order fuzzy logic controller (three papers). Finally,
... Show MoreThe isomerization of n-hexane on platinum loaded acidic zeolite was studied at atmospheric pressure, H2/nC6 molar ratios of 1-4 and temperature range of 240-270ºC. The measured kinetic data were fitted to an equation based on the bifunctional mechanism and by using independently obtained dehydrogenation and adsorption data. The activation energies of protonation (ΔHpro) and the elementary isomerization step (Eact,iso) and as well as the corresponding preexponential factor were simultaneously determined. The observed values of both ΔHpro and Eact,iso are in agreement with the results of quantum-chemical calculations.
