Abstract
Characterization of nanofibrillated cellulose (NFC) from oil palm empty fruit bunches (OPEFB) using ultrasound has been investigated. Cellulose from OPEFB pulp was gained by soda-anthraquinone (AQ) pulping and bleaching processes. The ultrasound with 20 kHz frequencies and 700 W output power was used in order to produce the NFC. Results were assessed by using fourier-transform infrared spectroscopy (FTIR) for structural analysis. The thermal stabilities were analyzed using thermogravimetric analysis (TGA) and crystalline index was measured using X-ray diffraction (XRD). Meanwhile, the morphology structure was carried out by field emission scanning electron microscope (FE-SEM) and scanning transmission electron microscopy (STEM). The diameters of the OPEFB-NFC were obtained between 5 to 23 nm. The FTIR results showed that removal of lignin, hemicelluloses and waxes after bleaching process. The TGA and XRD analysis showed that OPEFB-NFC had higher thermal stability and crystallinity as c.....

Abstract
This study was conducted to determine and compare the effects of different self-talk approach on performance and muscle activation during bench press exercise. Thirty trained men were recruited and were required to performed bench press exercise in three self-talk approach; i) motivational self-talk, ii) instructional self-talk, and iii) control condition (without self-talk). The performance of bench press is measured by the number of repetitions that were accomplished while the muscle activation was obtained from the pectoralis major muscle using electromyography (EMG) method. Results showed greatest number of repetitions was recorded when performing motivational self-talk followed by control condition and lastly instructional self-talk. In contrast, instructional self-talk recorded the highest pectoralis major muscle activation. As the conclusion, motivational self-talk is suggested to be adopted during resistance training as it was shown to produce greatest performance while been ec.....

Abstract
Amalan penerapan Kemahiran Berfikir Aras Tinggi (KBAT) dalam pengajaran guru bahasa Arab merupakan amalan yang perlu diterapkan secara eksplisit iaitu secara langsung. Walaupun KBAT telah lama dicanangkan dalam dunia pendidikan di Malaysia, namun tahap pengetahuan dan aplikasi KBAT dalam kalangan guru bahasa Arab masih di peringkat sederhana. Tidak dinafikan terdapat segelintir guru-guru bahasa Arab yang menerapkan KBAT dalam pengajaran mereka, namun penerapan ini adalah secara tidak langsung. Arus transformasi dalam dunia pendidikan mendorong guru-guru bahasa Arab mengubah cara pengajaran tradisional yang lebih kepada pemusatan guru kepada pengajaran yang berpusatkan kepada murid melalui penerapan KBAT ini. Justeru, kajian ini dijalankan bertujuan untuk meneroka amalan pengajaran menerapkan KBAT terhadap empat orang guru bahasa Arab di peringkat sekolah menengah di negeri Johor. Tiga persoalan kajian yang ditumpukan ialah i) Apakah amalan pengajaran guru bahasa Arab bagi m.....
