Review of iodine behavior from nuclear fuel dissolution to environmental release.

During nuclear fuel reprocessing, radioiodine, can be released. The speciation of iodine drives its volatility, and partitioning processes are highly variable because they depend on facility operating conditions. Starting from iodine behavior in the fuel and progressing to its behavior in the environment, this review article describes the current understanding of iodine partitioning during aqueous fuel reprocessing.

Critical Thinking in the Texting Age.

Objectives: Though texting has become a preferred way for clinicians to discuss patient care, surgeons report that texting detracts from trainees' education. Little research has explored how texting relates to education and more specifically to critical thinking - the problem-solving and decision-making processes central to safe patient care. As such, we aimed to identify how trainees perceived the effect of texting on critical thinking.

Is it gossip or feedback? Surgical attendings' perceptions of gossip within residency.

Objective: Gossip-evaluative talk about an absent third party-exists in surgical residency programs. Attending surgeons may engage in gossip to provide residents with feedback on performance, which may contribute to bias. Nevertheless, the perspectives of attending surgeons on gossip has not been studied.

Metal-Encapsulated, Polymer-Containing Halide Salt Composites as Potential Long-Term Hosts for Radioiodine: Evaluating Halmets, Polyhalmets, and Halcermets.

This paper presents composite waste form concepts for radioiodine immobilization including halide-metal () composites, polymer-halide-metal () composites, and halide-ceramic-metal () composites with data from experiments to evaluate these ideas. The encapsulant metal of choice for the pellets was Bi, and a cold-press-and-sinter approach was used for creating the pellets. A polymer (i.

Online videos of robotic-assisted cholecystectomies: more harm than good?

Background: Many surgeons use online videos to learn. However, these videos vary in content, quality, and educational value. In the setting of recent work questioning the safety of robotic-assisted cholecystectomies, we aimed (1) to identify highly watched online videos of robotic-assisted cholecystectomies, (2) to determine whether these videos demonstrate suboptimal techniques, and (3) to compare videos based on platform.

Expired blood transfusion and mortality outcomes in combat trauma patients.

Background: Expired blood can be transfused if clinically indicated but outcome data do not exist. We hypothesized that modestly outdated blood can effectively support a hemorrhaging patient until surgical control is achieved. This study assessed whether expired blood was associated with mortality in combat trauma patients.

Vascular Anastomoses and Dissection: A Six-Part Simulation Curriculum for Surgical Residents.

Introduction: As surgical technologies grow, so too do demands on surgical trainees to master increasing numbers of skill sets. With the rise of endovascular surgery, trainees have fewer opportunities to practice open vascular techniques in the operating room. Simulation can bridge this gap.

Synthesis and properties of anhydrous rare-earth phosphates, monazite and xenotime: a review.

The synthesis methods, crystal structures, and properties of anhydrous monazite and xenotime (REPO) crystalline materials are summarized within this review. For both monazite and xenotime, currently available Inorganic Crystal Structure Database data were used to study the effects of incorporating different RE cations on the unit cell parameters, cell volumes, densities, and bond lengths. Domains of monazite-type and xenotime-type structures and other AXO compounds (A = RE; X = P, As, V) are discussed with respect to cation sizes.

Comparing Peer and Faculty Feedback for Asynchronous Laparoscopic Skill Acquisition.

Objective: Traditionally, expert surgeons have provided surgical trainees with feedback about their simulation performance, including for asynchronous practice. Unfortunately, innumerable time demands may limit experts' ability to provide feedback. It is unknown whether and how peer feedback is an effective mechanism to help residents acquire laparoscopic skill in an asynchronous setting.

"Doing well": Intraoperative entrustable professional activity assessments provided limited technical feedback.

Background: Entrustable Professional Activities (EPAs) allow for the assessment of specific, observable, essential tasks in medical education. Since being developed in non-surgical fields, EPA assessments have been implemented in surgery to explore intraoperative entrustment. However, assessment burden is a significant problem for faculty, and it is unknown whether EPA assessments enable formative technical feedback.

Hanford low-activity waste vitrification: A review.

This paper summarizes the vast body of literature (over 200 documents) related to vitrification of the low-activity waste (LAW) fraction of the Hanford tank wastes. Details are provided on the origins of the Hanford tank wastes that resulted from nuclear operations conducted between 1944 and 1989 to support nuclear weapons production. Waste treatment processes are described, including the baseline process to separate the tank waste into LAW and high-level waste fractions, and the LAW vitrification facility being started at Hanford.

Confronting new challenges: Faculty perceptions of gaps in current laparoscopic curricula in a changing training landscape.

Background: Opportunities for residents to develop laparoscopic skills have decreased with the rise in robotic operations and the development of complex, subspecialized laparoscopic operations. Given the changing training landscape, this study aimed to identify laparoscopic surgeons' perceptions of gaps in current laparoscopic skills in general surgery, obstetrics-gynecology, and urology residency programs.

Methods: Laparoscopic surgeons who operate with residents participated in semi-structured interviews.

Home practice for robotic surgery: a randomized controlled trial of a low-cost simulation model.

Pre-operative simulated practice allows trainees to learn robotic surgery outside the operating room without risking patient safety. While simulation practice has shown efficacy, simulators are expensive and frequently inaccessible. Cruff (J Surg Educ 78(2): 379-381, 2021) described a low-cost simulation model to learn hand movements for robotic surgery.

Experience matters for robotic assistance: an analysis of case data.

Many robotic procedures require active participation by assistants. Most prior work on assistants' effect on outcomes has been limited in procedural focus and scope, with studies reporting differing results. Knowing how assistant experience affects operating room time could inform operating room case scheduling and provide an impetus for additional assistant training.

FAIR Island: real-world examples of place-based open science.

The relationship between people, place, and data presents challenges and opportunities for science and society. While there has been general enthusiasm for and work toward Findable, Accessible, Interoperable, and Reusable (FAIR) data for open science, only more recently have these data-centric principles been extended into dimensions important to people and place-notably, the CARE Principles for Indigenous Data Governance, which affect collective benefit, authority to control, responsibility, and ethics. The FAIR Island project seeks to translate these ideals into practice, leveraging the institutional infrastructure provided by scientific field stations.
