structured interview. The data analysis technique used the interactive model of Miles & Huberman with the stages of data collection, data reduction, data presentation, verification, and conclusion drawing. This research revealed no significant difference between teachers and preservice teachers in the perspective of climate change awareness in ECE. Both have diverse ways to express and think about the best thing to pursue climate change awareness in children. Participants also understand how to...

Purpose: It is increasingly acknowledged that auditory brainstem response (ABR) elicited by speech can reflect the listener’s perceptual cues of complex sound with replicability and reliability. This study sought to identify the brainstem responses evoked by Korean syllables and to characterize any relation between acoustic features of the speech and their neurophysiological responses at the brainstem level. Methods: Thirty young adults with normal hearing who were native Korean speakers...

of the nanocomposites was investigated by colorimetric and electrochemical tests with 3,3´,5,5´-tetramethylbenzidine (TMB) and H2O2 as the substrates. The results show that the synthesis of the nanocomposites was successfully performed. XRD analysis confirmed the crystalline structures of the NixZnxFe2O4/ MWCNT nanohybrids and MWCNTs. The main peaks of the NixZnxFe2O4/MWCNTs crystals were presented. The Ni0.25Zn0.25Fe2O4/MWCNT and Ni0.5Zn0.5Fe2O4/MWCNT nanocatalysts showed nearly similar...

of MgO and MnO2, respectively. The FESEM micrographs analysis showed a smooth but coarser structure in all the ACNFs. Meanwhile, the ACNF/MgO has the smallest fiber diameter (314.38±62.42 nm) compared to other ACNFs. The presence of MgO and MnO2 inside the ACNFs was also confirmed with EDX analysis as well as XRD. The adsorption capacities of each ACNF toward CH4 were tested with the volumetric adsorption method in which the ACNF/MgO exhibited the highest CH4 adsorption up to 2.39 mmol g?1....

The aim of this work was to evaluate the dielectric properties of impregnated and activated palm kernel shells (PKSs) samples using two activating agents, potassium carbonate (K2CO3) and sodium hydroxide (NaOH), at three impregnation ratios. The materials were characterized by moisture content, carbon content, ash content, thermal profile and functional groups. The dielectric properties were examined using an open-ended coaxial probe method at various microwave frequencies (1?6 GHz) and...
