Here, we report high output piezoelectric voltage generation using ZnO nanowires oxidized at high temperature. The study has been carried out to observe behavior of ZnO nanowires in the presence of strong oxidizing gases (O, CO2, and NO2) at elevated temperature. The focus of the research was to generate high piezoelectric voltage by using surface modified ZnO nanowires. VING (vertically integrated nanowire generator) has been exposed to oxidizing gases. ZnO nanowires oxidized with O2 have shown maximum high output voltage of 3.36 V at 200o C, showing net rise of 0.762 V as compared to voltage generated at room temperature. Similarly, ZnO nanowires modified with CO2 molecules have generated piezoelectric voltage of 2.589 V at 200o C, exhibiting a rise of 0.778 V as compared to the values recorded at room temperature and ZnO nanowires modified with NO2 have generated maximum output voltage of 3.307 V at 150o C, indicating net rise of 0.59 V to the voltage values achieved at room tempera.....

The viscosity of cellulose behaves differently and uniquely in various conditions. In this paper, we aim to report the viscosity measurement and related properties of low concentration of microcrystalline cellulose (MCC) in water using a magnetic bearing rheometer. Dynamic viscosities for MCC diluted in water at varying concentrations were measured using the standard rheometry technique. The viscosity of the MCC solution was found highly dependent on its concentration and the experiment temperature. This varieties behaviour and properties offers benefits to the current growing rapidly technology applications such as in food, pharmaceutical cosmetics and textile. ? 2021, Journal of Advanced Research in Fluid Mechanics and Thermal Sciences.

During the coronavirus disease (COVID-19) pandemic, different technologies, including telehealth, are maximised to mitigate the risks and consequences of the disease. Telehealth has been widely utilised because of its usability and safety in providing healthcare services during the COVID-19 pandemic. However, a systematic literature review which provides extensive evidence on the impact of COVID-19 through telehealth and which covers multiple directions in a large-scale research remains lacking. This study aims to review telehealth literature comprehensively since the pandemic started. It also aims to map the research landscape into a coherent taxonomy and characterise this emerging field in terms of motivations, open challenges and recommendations. Articles related to telehealth during the COVID-19 pandemic were systematically searched in the WOS, IEEE, Science Direct, Springer and Scopus databases. The final set included (n = 86) articles discussing telehealth applications with respe.....

Teachers play a significant role in curbing Drug and Substance Abuse (DSA) because they spend much of their time with students in school. The teaching competency of teachers is needed in drug and substance abuse prevention. Some studies found that the school teachers still have lack knowledge to talk about DSA in their classroom and school environment. It is assumed that the problems are related to the teaching competency of teachers. This paper aims to discuss the role of teaching competency of teachers for curbing DSA in Malaysian secondary schools. The methodology used in this study is a conceptual approach, which involves con-ducting literature research and critical thinking to develop a hypothetical concept. This paper has classified the teaching competency for curbing DSA into abilities of teachers to (1) Set up teaching planning (2) Curric-ulum (3) Pedagogical knowledge (4) Learning strategies (5) Classroom environment and (6) Social approach. These competencies help teachers im.....

This study aimed to examine the implementation of the teaching and facilitation (PdPc) methods among lecturers and their influence on students' interests in learning Geography. Students' interests in learning were measured based on two aspects: emotionaland cognitive aspects. A survey approach was used in this study, involving a total of 120 final year students (seventh semester) who have completed all the eight Geography core subjects offered in Universiti Pendidikan Sultan Idris (UPSI). The sample was selected using a simple random sampling method. A set of questionnaires with 40 items was distributed to the respondents. The findings from the descriptive analysis indicated that the overall students' interests in learning Geography subjects in UPSI was at a high level (M=4.19, SD=0.83). Additionally, the analysis also discovered that the implementation of the PdPc methods in the Geography subjects using the traditional learning method was moderate (M=2.72, SD=1.34), while the game-bas.....

Drug education in school is one of the efforts of the government for erad-icating drug abuse among young children in educational institutions. Teachers play significant role in drug prevention because they spend much of their time with students at school. The objective of this study is to highlight the teachers` self-efficacy and its impact on level of drug abuse in Malaysian schools. This study employed a qualitative approach acquired through secondary data with literature review.. The study showed that teachers` self-efficacy has contributed to the quality of drug education among students due to sdominant components, such as: (1) Teaching performance in the classroom; (2) Developing cooperative learning; (3) Teachers` personal involvement; (4) Teachers` training; and (5) Students` engagement in drug prevention. As the conclusion, teachers` self-efficacy is a critical determinant factor to improve the quality drug education, es-pecially in classroom situation. The 5 aspects also deter.....

Despite extensive research on ICT integration among teachers, limited knowledge was given to understand ICT's successful integration among teachers. For those purposes, a single-case study aimed to explain the successful integration of ICT by teachers into teaching in one national primary school in Malaysia. Data were collected using a multi-method of data collection, including in-depth interviews, non-participants observations, and document analysis. The results discovered three models that lead to teachers' successful ICT integration in teaching, explaining how the interactions between the contradictions, causes of contradictions, and resolutions of contradictions have hindered or influenced the teachers to integrate ICT in their teaching. The findings indicate that the activity system of department and school (prior activities) affecting the classroom activity system (recent activity) led to the successful integration of ICT by teachers in teaching. ? 2022 American Society of Civil .....

There is no clear definition of what constitutes an ideal teacher educator, particularly from the perspective of Malaysian educators. Developing teacher educators? vision of an ideal teacher ensures that teachers have high levels of professional, personal, and contextual dimensions in teaching practices, including competence in the practice of professional teaching, knowledge, and understanding. Therefore, the objective of this study was to find out the range of visions of what it is to be a good teacher educator in a Malaysian teacher education institution. Seventeen teacher educators from an established university in Malaysia participated in the study. A survey consisting of eight questions was used as the research instrument. The data obtained from the questionnaire were analysed by using descriptive and textual analysis techniques. The findings reveal certain criteria of an ideal teacher such as possessing sound subject matter knowledge, mastery of both generic and content-specific.....

The brain?computer interface (BCI) technique represents one of the furthermost active interdisciplinary study domains and includes a wide knowledge spectrum from a different disciplines such as medicine, neuroscience, machine learning and rehabilitation. The motor imagery (MI) technique based on BCI has been broadly applied in rehabilitation especially for upper limb motor movement where people with disabilities need to restore or improve their walking capability. Nowadays, virtual reality is a beneficial scheme for BCI users because it proposes a relatively cost-effective, safe way for BCI users to train and explain themselves in using BCI in a computer-generated environment earlier than in a real-life scenario. Depicting the whole picture for signal processing techniques and methods utilised in MI-based BCI training environments is difficult. In addition, numerous challenges and open issues regarding signal processing and pattern recognition exist in the literature of the current top.....

A cationic complex of iridium(III), [Ir(2,4-F2ppy)2 (F2 bpyta)]PF6 utilizing 1,2,4-triazolepyridyl as an anchillary ligand modified with a 2,6-difluorobenzyl substituent was synthesized and characterized. The aromatic signals of pyridyltriazole and phenylpyridine proton were detected in the1 H-NMR spectrum between 10.00 and 7.00 ppm. Only one singlet peak was detected at 8.46 ppm H(8) shifted to the upfield, demonstrating that C5 was coordinated to the central iridium metal. The bands exhibited in the range of 1555?1431 cm?1 in the IR spectrum because of the C=C and C=N aromatic rings stretching pyridine, phenyl, and triazole vibrations. The UV-Vis absorption spectrum showed a slight and broad absorbance peak at lower energy at a lmax = 371 nm (e = 6129 M?1 cm?1) in the visible range due to1 MLCT and3 MLCT transitions. Blue emission was observed in the steady-state emission spectral of [Ir(2,4-F2 ppy)2 (F2 bpyta)]PF6 and the other two previously synthesized iridium(III) complexes in CH.....
