The dynamic analyses of a reversible bending fatigue testing system designed for the spent nuclear fuel (SNF) vibration integrity study was presented in this paper. Different design concepts were evaluated to assist the U-frame tester development. A finite element analysis (FEA) based on the vertical test setup was established to simulate the U-frame test system dynamic performances. The FEA results provided general guideline on predicting the dynamic behaviors of U-frame bending fatigue system for testing SNF. The initial vertical test setup design concepts were investigated in detail and the associated deficiencies were also discussed in the paper. The horizontal test setup was also evaluated using FEA. Based on dynamic analysis results, the horizontal test setup with symmetric loading profile was recommended for developing a reversible U-frame bending fatigue testing system.

The exposure durations of a vertical test line and a tilted inducing grating were varied and the tilt illusion thus generated was found to change as a function of this variation. Significant direct effects (acute-angle expansion) and indirect effects (acute-angle contraction) were found to occur at times consistent with Andrews's estimate of the time course of inhibition in the visual system when the inducing grating had a spatial frequency of 10 cycles deg−1. However, a 2 · 71 cycles deg−1 grating gave significant effects at exposure durations of 10 as well as 1000 ms, while in a further experiment a 10 · 91 cycles deg−1 grating gave significant effects at 1000 ms only. These results seem to suggest that orientation interactions thought to be due to inhibition (direct effect) and disinhibition (indirect effect) may occur within both sustained and transient channels with concomitant differences in time constants.

What are the experiences of the researchers in doing research with Indigenous People (IP)? How do such experiences influence their thoughts, values, and advocacies with IP aspirations? What prognosis can be derived from their experiences? To answer such queries, a qualitative research was conducted and thereby revealed that the study participants describe research with IP as an in depth investigative process which upholds relevance, rigor, artistry and ethical standards.  It is undertaken through the use of diverse research methods like focus group discussion, survey, observation and in-depth interview, life stories or genealogy, three generation vertical test, document and photo analysis.  It involves face-to-face encounters, demands trustworthiness and credibility, and advances moral decency.  It enhances competence and boosts confidence not just in conducting ethnographic exploration but in pursuing the liberative education.  Furthermore, the participants developed the value of sensitivity to IP rights and culture, the virtue of respect to privacy, anonymity and confidentiality, the enthusiasm to share research-based knowledge through forums, conferences, meetings, trainings, and publications, and the solidarity and camaraderie with the IPs – immersion in their real life, discernment on their plight, and commitment in their struggle for their rights to ancestral domain and self-determination. Finally, for them, doing research with IP is noble. It is a call. <br />

A stationary vertical test grating appears to drift to the left after adaptation to an inducing grating drifting to the right, this being known as the motion aftereffect (MAE). Pattern-specific motion aftereffects (PSMAEs) induced by superimposed pairs of gratings in which the component gratings drift up and down but the observer sees a single coherent plaid drifting to the right have been investigated. Two experiments are reported in which it is demonstrated that the PSMAE is tuned more to the motion of the pattern than to the orientation and direction of motion of the component gratings. However, when subjects adapt to the component gratings in alternation, aftereffect magnitude is dependent upon the individual grating orientations and motion directions. These results can be interpreted in terms of extrastriate contributions to the PSMAE, possibly arising from the middle temporal area, where some cells, unlike those in striate cortex (V1), are tuned to pattern motion rather than to component motion.
