(3-glycidoxy propyl trimethoxysilane) coupling agent. Toughness was determined using the double cantilever test, together with surface analysis after failure using scanning electron microscope. The presence of polysulfone particles improved the fracture behavior of the composite, but fiber-matrix adhesion seemed to play a very important role in the performance of the composite material. There appeared to be a synergy between the matrix modifier and the fibermatrix adhesion coupling agent.

The attachment of 2-aminobenzamide to carboxylated multi-wall carbon nanotubes (MWCNTs)- COOH was achieved through the formation of amide bonds. Then, the functionalized MWCNTs, MWCNT-amide, were treated by phosphoryl chloride to produce MWCNT-quin. The products were characterized by Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, thermogravimetric analysis, derivative thermogravimetric, steady-state fluorescence spectroscopy, and solubility testing....

one of the critical elements in evaluating writing quality, and several factors such as major/content knowledge, age, gender, or language proficiency influence the overall quality of writing even when L2 learners freely choose their writing topics. This study explored the relationships between overall language proficiency and lexical diversity, and between writing genres and lexical diversity when Korean EFL writers had freedom to choose their topics. Seventy-two university students participated...

in the previous studies, the findings have been inconsistent. The present study explored the effect of partners' proficiency levels on test scores in a paired speaking test. Participants included a total of 107 female adults and college students. Based on their standardized speaking test scores, they were grouped into five levels: Superior, High, Intermediate, Novice-high, and Novice proficiency level. Then, 90 test takers completed the test three times with being paired with three different...

Cognitive, and Social Presence) and institutional support toward learner satisfaction by applying structural equation modeling. After satisfying the fitness of the measurement and the structural models, this study confirmed the direct effect of Teaching Presence, Cognitive Presence, and institutional support on learner satisfaction. Social Presence, however, did not show a significant causal relationship toward satisfaction, probably due to the lower level of learners' perception and needs for...

Observational inter-rater reliability study. Methods: Fifty-five healthy participants (25 men, 30 women) participated in this study. PC-BMW and P-US were randomly measured at the UT and TrA muscles. Two examiners randomly obtained the images of all participants in 3 test sessions lasting 2days. Intra-class correlation coefficients (ICCs), standard error of measurement, contraction ratio, and correlation were used to estimate reliability and validity. Pearson’s correlation coefficients were used...
