Assessment of mechanical properties and microstructure characterizing techniques in their ability to quantify amount of cold work in 316l alloy

Stress corrosion cracking (SCC) behavior is a matter of concern for structural materials, namely, stainless steels and nickel alloys, in nuclear power plants. High levels of cold work (CW) have shown to both reduce crack initiation times and increase crack growth rates. Cold working has numerous effects on a material, including changes in microstructure, mechanical properties, and residual stress state, yet it is typically reported as a simple percent change in geometry. There is need to develop a strategy for quantitative assessment of cold-work level in order to better understand stress corrosion cracking test data. Five assessment techniques, commonly performed alongside stress corrosion cracking testing (optical microscopy (OM), electron backscatter diffraction (EBSD), X-ray diffraction (XRD), tensile testing, and hardness testing) are evaluated with respect to their ability to quantify the level of CW in a component. The test material is stainless steel 316L that has been cold-rolled to three conditions: 0%, 20%, and 30% CW. Measurement results for each assessment method include correlation with CW condition and repeatability data. Measured values showed significant spatial variation, illustrating that CW level is not uniform throughout a component. Mechanical properties (tensile testing, hardness) were found to correlate most linearly with the amount of imparted CW

Cosmogenic-neutron activation of TeO2 and implications for neutrinoless double- β decay experiments

Flux-averaged cross sections for cosmogenic-neutron activation of natural tellurium were measured using a neutron beam containing neutrons of kinetic energies up to ∼800 MeV and having an energy spectrum similar to that of cosmic-ray neutrons at sea level. Analysis of the radioisotopes produced reveals that Ag110m will be a dominant contributor to the cosmogenic-activation background in experiments searching for neutrinoless double-β decay of Te130, such as the Cryogenic Underground Observatory for Rare Events (CUORE) and the Sudbury Neutrino Observatory Plus (SNO+). An estimate of the cosmogenic-activation background in the CUORE experiment has been obtained using the results of this measurement and cross-section measurements of proton activation of tellurium. Additionally, the measured cross sections in this work are also compared with results from semiempirical cross-section calculations

A Method for Providing High-volume Interprofessional Simulation Encounters in Physical and Occupational Therapy Education Programs

With an increasing emphasis on interprofessional education within the allied health professions, simulation has potential for being a useful teaching modality for providing collaborative learning experiences for occupational and physical therapist students. However, there are many challenges associated with conducting simulations with large numbers of students. We describe the design, planning, cost, and support staff time required for conducting an interprofessional simulation of the intensive care setting, including a methodology for maximizing resources and student opportunities for participation for 64 physical and occupational therapy students over a 4-hour time period. Qualitative analyses of student experiences are also presented

Genome Editing Technology, CRISPR Cas-9, Provides a Potential Future for Xenotransplantation: Can Pigs Become Our New Organ Donors?

Organ shortage has been a significant issue in United States for many decades. There were over 116,000 people on the transplant waiting list as of August 2017, with a new person added every 10 minutes. Animals have been considered as potential organ donors for humans, with the pig being the most ideal candidate because of its excellent breeding profile, low maintenance costs, large litters, rapid growth and organ similarity. A notable challenge that comes with porcine organs are endogenous retroviruses that establish themselves in the DNA of offspring in utero, thereby allowing for no time to prevent infection and integration. Porcine endogenous retroviruses (PERVs) have the ability to infect human cells and therefore must be removed or inactivated before considering transplantation. Genome editing technology, CRISPR-cas9, has been recently successful in targeting and inactivating PERVs in porcine fetal cell lines. Using PERVinactivated cells, reproductive technologies have allowed for fertilization, implantation and the successful birth of 37 PERV-inactivated piglets from 17 sows. At this time, 15 piglets remain alive with the oldest piglet being 4 months of age. The success of this technology takes us one step closer to finding potential organ donors outside of our own species and instilling hope back into those who may need an organ transplant in the future

Time to Ask Program at Greater Portland Health [Infographic]

The goals of the Time to Ask education and quality improvement program of the Lunder Dineen include increasing the capacity of interprofessional care teams in discussing alcohol use with the patients through the screening, brief intervention, and referral (SBIRT) process, and expanding providers\u27 use of screening and monitoring unhealthy alcohol use of their patients. This evaluation infographic visualizes the impact of Greater Portland Health\u27s use of this program.

To alleviate group members’ physiological stress, supervisors need to be more than polite and professional

This is the final version. Available on open access from SAGE Publications via the DOI in this recordAlthough stressors are common in group life, people cope better when group authorities treat them with care/concern. However, it remains unclear whether such treatment affects individuals’ physiological stress. In this experiment, individuals engaged in an interview known to increase cortisol (stress biomarker). Surrounding the interview, an ingroup supervisor treated them with standard professionalism (politeness; control), explicit care/concern (high-quality treatment), or disregard (poor-quality treatment). While those in the control condition experienced a spike in cortisol, individuals in the high-quality treatment condition did not experience this physiological stress (cortisol). Those shown poor-quality treatment also did not exhibit stress, suggesting the explicit disregard for them may have undermined the interview’s legitimacy, thereby removing social evaluative threat. Paralleling past research, self-reported stress did not reflect individuals’ physiological stress (cortisol). Overall, results suggest that to alleviate members’ physiological stress, supervisors need to be more than polite and professional – also demonstrating care/concern for them as individuals

Medication Assisted Treatment: Prescription Drug and Opioid Addiction Expansion Project

Greater Portland Health (GPH) in collaboration with Preble Street Resource Center was awarded a Medication Assisted Treatment: Prescription Drug & Opioid Addiction (MOUD-PDOA) grant from SAMHSA. The GPH MOUD-PDOA project will include a mixed-methods evaluation led by Catherine E. Cutler Institute. The evaluation team will build knowledge and provide feedback to inform the implementation and refinement of the GPH MOUD-PDOA Program. Evaluation Goals: Document program strategies and identify barriers and facilitators to implementation Examine the efficacy of using a continuum of treatment services to increase access to MOUD among vulnerable populations in underserved communities Assess the impact of the intervention strategies on patient engagement and outcomes This report highlights the process and outcome evaluation data collected during Year 1.

Introducing the Black Male Life Success Theory

For decades, literature has described success for Black males as an unattainable phenomenon due to the nearly insurmountable hardships they face. Although this narrative has changed within the last 15 years, there are insignificant amounts of research on Black male life success. This study sought to identify and discover how 14 Black males in Central Virginia achieved life success. This study defined life success for Black males utilizing the psychological construct of well-being. This grounded theory study identified a framework for Black male life success which included a definition for life success as well as common attributes and circumstances or Black males on their journey towards life success
