2018 acc hrs nasci scai scct expert consensus document on optimal use of ionizing radiation in cardiovascular imaging best practices for safety and effectiveness part 2 radiological equipment operation dose sparing methodologies patient and medical Personnel Protection
Catheterization and Cardiovascular Interventions, 2018Co-Authors: Acc Task Force On Expert Consensus Decision PathwaysAbstract:The stimulus to create this document was the recognition that ionizing radiation-guided cardiovascular procedures are being performed with increasing frequency, leading to greater patient radiation exposure and, potentially, to greater exposure to clinical Personnel. While the clinical benefit of these procedures is substantial, there is concern about the implications of medical radiation exposure. ACC leadership concluded that it is important to provide practitioners with an educational resource that assembles and interprets the current radiation knowledge base relevant to cardiovascular procedures. By applying this knowledge base, cardiovascular practitioners will be able to select procedures optimally, and minimize radiation exposure to patients and to clinical Personnel. "Optimal Use of Ionizing Radiation in Cardiovascular Imaging - Best Practices for Safety and Effectiveness" is a comprehensive overview of ionizing radiation use in cardiovascular procedures and is published online. To provide the most value to our members, we divided the print version of this document into 2 focused parts. "Part I: Radiation Physics and Radiation Biology" addresses radiation physics, dosimetry and detrimental biologic effects. "Part II: Radiologic Equipment Operation, Dose-Sparing Methodologies, Patient and Medical Personnel Protection" covers the basics of operation and radiation delivery for the 3 cardiovascular imaging modalities (x-ray fluoroscopy, x-ray computed tomography, and nuclear scintigraphy). For each modality, it includes the determinants of radiation exposure and techniques to minimize exposure to both patients and to medical Personnel.

european society for neurogastroenterology and motility recommendations for conducting gastrointestinal motility and function testing in the recovery phase of the covid 19 pandemic
Neurogastroenterology and Motility, 2020Co-Authors: Jan Tack, Tim Vanuytsel, Jordi Serra, Anna Accarino, Vincenzo Stanghellini, Giovanni BarbaraAbstract:BACKGROUND: During the peak of the COronaVIrus Disease 2019 (COVID-19) pandemic, care for patients with gastrointestinal motility and functional disorders was largely suspended. In the recovery phases of the pandemic, non-urgent medical care is resumed, but there is a lack of guidance for restarting and safely conducting motility and function testing. Breath tests and insertion of manometry and pH-monitoring probes carry a risk of SARS-CoV-2 spread through droplet formation. METHODS: A panel of experts from the European Society for Neurogastroenterology and Motility (ESNM) evaluated emerging national and single-center recommendations to provide the best current evidence and a pragmatic approach to ensure the safe conduct of motility and function testing for both healthcare professionals and patients. RESULTS: At a general level, this involves evaluation of the urgency of the procedure, evaluation of the infectious risk associated with the patient, the investigation and the healthcare professional(s) involved, provision of the test planning and test units, education and training of staff, and use of Personnel Protection equipment. Additional guidance is provided for specific procedures such as esophageal manometry, pH monitoring, and breath tests. CONCLUSIONS AND INFERENCES: The ESNM guidelines provide pragmatic and appropriate guidance for the safe conduct of motility and function testing in the COVID-19 pandemic and early recovery phase.

oak ridge national laboratory corrective action plan in response to tiger team assessment
1991Co-Authors: Michael A KuliashaAbstract:This report presents a complete response to the Tiger Team assessment that was conducted to Oak Ridge National Laboratory (ORNL) and at the US Department of Energy (DOE) Oak Ridge Operations Office (ORO) from October 2, 1990, through November 30, 1990. The action plans have undergone both a discipline review and a cross-cutting review with respect to root cause. In addition, the action plans have been integrated with initiatives being pursued across Martin Marietta Energy Systems, Inc., in response to Tiger Team findings at other DOE facilities operated by Energy Systems. The root cause section is complete and describes how ORNL intends to address the root cause of the findings identified during the assessment. This report is concerned with reactors safety and health findings, responses, and planned actions. Specific areas include: organization and administration; quality verification; operations; maintenance; training and certification; auxiliary systems; emergency preparedness; technical support; nuclear criticality safety; security/safety interface; experimental activities; site/facility safety review; radiological Protection; Personnel Protection; fire Protection; management findings, responses, and planned actions; self-assessment findings, responses, and planned actions; and summary of planned actions, schedules, and costs.

multistable architected materials for trapping elastic strain energy
Advanced Materials, 2015Co-Authors: Sicong Shan, Sung Hoon Kang, Jordan R Raney, Pai Wang, Lichen Fang, Francisco Candido, Jennifer A LewisAbstract:We combine 3D printing and numerical analysis to design a new class of architected materials that exhibits controlled trapping of elastic energy. These programmed structures contain beam elements with geometries that are specifi cally designed to enable large, local bistable deformations. When these materials are mechanically deformed, the beams locally reconfi gure into a higher-energy, yet stable, deformed state, akin to a phase transformation. The energy applied during deformation, whether via low rate quasistatic loading or via impact tests, can be stored in this manner until a suffi cient reverse force is applied that allows the deformed beams to return to their original confi guration. The mechanism of energy absorption stems solely from the structural geometry of the printed beam elements, and is therefore both materials- and loading rate- independent. These architected materials offer a new strategy for signifi cantly enhancing energy absorption. Energy-absorbing materials are widely deployed for Personnel Protection, crash mitigation in automobiles and aircraft, and protective packaging of delicate components. Many strategies have been investigated to create materials that effi ciently dissipate mechanical energy, including plastic deformation in metals, [ 1–4 ] fragmentation in ceramics, [ 5 ] and rate-dependent viscous processes. [ 1,6,7 ] However, in all of these systems there are challenges associated with either reusability or rate dependency. Most recently, mechanical metamaterials have been fabricated in novel geometries to realize recoverable energyabsorbing behavior in elastic systems, [ 8–11 ] suggesting novel strategies for mechanical dissipation of energy.
