Waste cooking palm oil (WCPO) has been utilized as a green carbon source for the synthesization of graphene by double thermal chemical vapor deposition. The WCPO was placed in the first furnace (precursor furnace) whereas nickel was placed in the second furnace (deposition furnace). The deposition temperatures were varied between 850 and 1100��C. Raman results reveal the highest 2-D peak for the sample synthesized at 1000��C, which indicates the high-quality formation of graphene. Besides, the sample also shows good crystallinity with a sharp peak at 26.8� which represents the hexagonal graphite structure and the introduction of graphene sheet formation. On the other hand, the FESEM image displays hexagonal structures since the graphene layers were formed after the precipitation of the carbon. Meanwhile, the UV-Vis result shows the highest reflectance in the visible light region which indicates the presence of the graphene layer on Ni. [Figure not available: see fulltext.] ? .....

Globalisation and the rapid growth of technologies call for ease and automation in different aspects, including in tourism. Tourism is an important sector in Malaysia as it generates income for the country. In recent years, Malaysia has seen a surge in the arrival of high-spending Arab tourists. This reflects the need to provide a tool, specifically a tourism mobile application in the Arabic language, that could help ease their journey in Malaysia. Thus, this study aims to determine the usability of the i-Suyyah mobile application for Arab tourists in Malaysia. The data obtained were analysed using the Fuzzy Delphi method, and twelve experts were selected to analyse the fuzziness consensus. It was found that the i-Suyyah mobile application recorded a high percentage of expert consensus, specifically on its usability. All usability items have reached unity with the threshold value of d 0.2, and the percentage of consensus among the expert group is more than 83%. ? 2021, Universidad de H.....

Overweight and underweight are common issues among children in Malaysia and thus, Malaysian government has launched several campaigns to combat these problems. Previous research show that BMI at certain age could be predicted earlier so that early intervention can be initiate. Most of the study are very specific to some locality and certain ethnic, make it hard to generalize to the whole Malaysian. This research aims to investigate significant positive predictors of changes in Body Mass Index (BMI) of young children aged from 12 months to 48 months and to develop a prediction model for their BMI status (normal, overweight, obese, risk of overweight, underweight, and severe underweight). Data consisting of 558 records with 16 attributes involving 18,226 children, who had registered at the National Child Data Centre (NCDC) were analyzed and predicted using the decision tree algorithms of Rapid miner. The BMI of 48 months-old children can be reliably predicted by their BMI statuses at the.....

This paper aims to identify the roles of innovative capability, especially on absorptive capability in improving Malaysian export performance. Specifically, this paper provides a definition of absorptive capability, innovative capability, and export performance obtained from previous studies. This is a content analysis involving relevant articles that were identified using both electronic and manual bibliographic search methods. Overall, there is empirical evidence on the roles of innovative capability that serve as a mediator in the relationship between absorptive capability and export performance. This study provides one of the few attempts in assessing existing literatures and examining the roles of innovative capability in the relationship between absorptive capability and export performance. Thus, it provides a reference point that can stimulate and guide future research on the roles of innovative capability as dynamic capabilities. ? 2021, Allied Business Academies. All rights re.....

This study aimed to evaluate job-related affective well-being, perceived supervisor support and positive feedback as contributing factors to work engagement of lecturers in the context two countries in the South East Asia. A total of 134 lecturers of one university in Malaysia and one university in Indonesia were recruited through simple random sampling. The research instruments were Job Affective Well-Being Scale, Survey of Perceived Supervisor Support and Utrecht Work Engagement Scale, while the statement of positive feedback was given in a hardcopy form or via personal e-mail. Multiple regression analysis showed that job affective well-being (? = 0.49, p = .01) and perceived supervisor support (? = 0.27, p = .01) made significant contribution to the prediction of work engagement. However, positive feedback statement (? = 0.02, p = .75) was not a significant predictor of work engagement. Therefore, a better strategy of the implementation of positive feedback should be considered in f.....

The blending of hydrophilic materials with hydrophobic polymers has been reported with agglomeration due to their functional group immiscibility properties. In this study, the properties of PLA/CNF biocomposite were enhanced with amphiphilic chitosan produced by a substitution reaction. The substitution reaction was studied with FT-IR analysis. The amphiphilic chitosan was used as part of the matrix PLA/chitosan and reinforced with CNF to obtain PLA/chitosan/CNF biocomposite using combined melt extrusion and compression molding technique. The morphology and structural bonding of amphiphilic chitosan added in the biocomposite were studied with SEM, XRD, and FT-IR. Furthermore, the mechanical, thermal, and wettability properties of PLA/chitosan/CNF composite were studied with tensile analysis, thermogravimetry analysis, differential scanning calorimetry, water absorption, thickness swelling, and contact angle test. The preparation of the amphiphilic chitosan was successful, as observed f.....

This survey study aims to identify the relationship between teacher's pedagogical content knowledge (PCK), teaching styles and efficacies among primary school mathematics teachers in Larut Matang and Selama, Perak, Malaysia. Three types of questionnaires and one test were used for data collection. The sample consisted of 208 teachers, was selected using a stratified random sampling technique. Data were analyzed using Pearson correlation and multiple regression. Correlation analysis showed a weak positive relationship between teachers' PCK level and Fractional conceptual knowledge level. Multiple regression analysis result showed a significant relationship between teachers' teaching styles and PCK levels towards teacher's efficacies. As implication, this study's results can be used as a guide in planning activities involving teachers' professional, so that the quality standard of mathematics teachers can be improved and the effectiveness of teaching can be achieved. ? 2021 RIGEO.

The flipped classroom is believed to promote a sense of continuity in the classroom and nurture learner autonomy. If students learn to self-regulate, they are more likely to gain desired skills. This study investigates self-regulated learning (SRL) motivation as possible predictors of Asian undergraduate students? English proficiency in a flipped online English as a foreign language (EFL) classroom. Undergraduate Japanese EFL students were paired with counterparts in Malaysia. Working in a computer ? mediated environment, learners worked together to complete tasks. Learners? output and thoughts about the experience were documented online, and questionnaires were used to elicit data on self-regulation and motivation. We found that metacognitive and cognitive strategy use, combined with peer learning promoted by learners? self-efficacy leads to improved English proficiency.

Objectives: The aim of this review was to provide an overview of researches presenting evidence for a relationship between physical well-being and cognitive outcomes in 2-7 year old typically developing children. Design: A systematic review. Methods: Articles involved in this review were from Science Direct, EBSCO and WoS. In total, 21 articles were included in this review. Two reviewers assessed the methodological quality independently. Results: The evidence for or against the relationship between physical well-being and cognitive outcomes was not sufficient. However, there was weak-to-strong evidence for some relationships between underlying categories of physical well-being and cognitive outcomes, including complex motor skills and higher order cognitive skills. Conclusions: There were some relationships between motor and cognitive skills. It offered insight into possible interventions designed to complex motor skills which may be beneficial for both motor and higher order cognitive.....
