Characterization of the thermal gradients within supersonic and hypersonic flows is essential for understanding transition, turbulence, and aerodynamic heating. Developments in novel, impactful non-intrusive techniques are key for enabling flow characterizations of sufficient detail that provide experimental validation datasets for computational simulations. In this work, Resonantly Ionized Photoemission Thermometry (RIPT) signals are directly imaged using an ICCD camera to realize the techniques 1D measurement capability for the first time.

Over the past 30 years, the scientific community has been increasingly challenged to provide the next generation of researchers with training in responsible conduct of research (RCR). Although RCR courses, workshops, and seminars are now routinely taught internationally, there is little uniformity in goals, content, pedagogy, duration, class size, or methods of assessment. The result is a mixed picture of effectiveness.

Molecular chaperones enable a cellular defense by reducing or compartmentalizing these insults. Small heat shock proteins (sHsps) engage proteins early in the process of misfolding and can facilitate their proper folding or refolding, sequestration, or clearance.

We report a randomized trial of a research ethics training intervention designed to enhance ethics communication in university science and engineering laboratories, focusing specifically on authorship and data management. The intervention is a project-based research ethics curriculum that was designed to enhance the ability of science and engineering research laboratory members to engage in reason giving and interpersonal communication necessary for ethical practice. The randomized trial was fielded in active faculty-led laboratories at two US research-intensive institutions.

On the assumption that providing faculty with tools and resources to address the ethical dimensions of the practice of research would be useful, a new workshop was convened ten times across seven academic institutions and at the annual meeting of a professional society. Workshops were attended by 91 faculty, 71 (78% response rate) of whom completed evaluations strongly supportive of the value of the workshop.
