PVC used as insulation material for industrial power cable was tried to evaluate degradation by Small Punch test (SP test) as a simple and easy assessment method. It was suggested that the SP test can analyze chemical changes from the correlation with IR. Qualitative assessment shows agreement between SP test and tensile test, and it is possible to apply to evaluation of strength at long aging times. However, the failure load in the SP test samples is complex and scattered, so that detailed study on SP test is required. Thus, we focused chemical reaction mechanisms and tried to clarify their influence on SP behavior. Molecular weight change was measured for each aging time by SEC and discussed how polymer chains are cut based on IR result. We discuss the relationship between molecular weight and the mechanical properties of PVC by SP test. The effectiveness of SP test as the evaluation method for residual life prediction will be addressed.

Abstract This article investigates a language learner’s cognitive ability (i.e., form-orientation) in detecting the corrective nature of non-salient feedback, by reviewing the operationalizations and reported effectiveness of recasts in recent SLA literature. Two directionalities which seem to have resulted in the divergent findings of recast effectiveness will be discussed: (a) operationalized (or intact) explicitness or implicitness of recasts, which designate the level of noticeability (i.e., feedback factors) and (b) contextual variables, including where a study was conducted and participants’ learning background, which ultimately influence the effectiveness of recasts on language development (i.e., learner factors). To expose learner factors accordingly, learning contexts and learner’s explicit knowledge will be discussed as possible variables in forming cognitive orientation. By taking an interdisciplinary approach to explore the constitution of the orientation, namely, SLA, psycholinguistic, and sociocultural approaches, this article concludes that contexts and explicit knowledge interdependently create the cognitive ability that enhances the noticing of implicit recasts, which then arguably determines subsequent language development.

Uniaxial tension experiments and electron back-scatter diffraction were performed on a bimodal Ti-6Al-4V alloy to study the deformation behavior of primary hcp-Ti (αp). It was found that the obtained tensile strength and elongation of the studied Ti-6Al-4V from the in-situ tensile test are higher than of which derived from the regular tensile test. The strain could be accommodated by the activation of slip systems and by grain rotations during the deformation. The prismatic slip is the primary slip mode of αp. According to kernel average misorientation analysis, we found that the dislocations mainly distributed near grain boundaries and subgrain boundaries, and partially located around slip lines. Calculated rotation angles and average rotation rates show that the rotation heterogeneity occurred among grains and subgrains.

For advanced and strategic management of gravel riverbed restoration and stopping of woodland overgrowth, movable riverbed simulations and vegetation dynamic models that can describe a ‘detailed riverbed materials’ transport’ influencing the vegetation dynamics and estimate the creation area of a gravel riverbed are required. As first steps we verified the hypothesis whether high-accuracy observation data using UAV and SfM improve the accuracy of water flow condition and movable riverbed simulation that can describe the riverbed materials’ transport in detail. In the results, High-precision river morphology using UAVs offers the ability to improve the movable riverbed simulation. And these progresses indicated possibilities of UAV and SfM to develop vegetation dynamics model considering the riverbed materials’ transport.
