Investigating the Impact of Hardness on Dielectric Breakdown Characteristics of Polyurethane.

Polymeric materials play a vital role in high-voltage insulation, but their insulating properties can deteriorate over time, leading to insulation failures. The presence of voids resulting from manufacturing defects or external stresses can create a highly divergent field, further contributing to this issue. However, certain polymers, such as polyurethane (PU), possess self-healing properties that enable them to repair these voids and restore a uniform electric field distribution, thereby ensuring the reliability of the insulation.

An MRT workforce shortage is no laughing matter.

The Canadian Association of Medical Radiation Technologists (CAMRT) has collected profession-specific health human resource (HHR) and impact data to understand medical radiation technologist (MRT) workforce models. The cumulation of these efforts provides longstanding HHR trends that can inform medical imaging and radiation therapy departments. The data demonstrates the healthcare system is neglecting workplace safety across Canada and is causing negative physical and psychological impacts on MRTs as a direct result.

A computational study on the effects of fast-rising voltage on ionization fronts initiated in sub-mm air and CO[Formula: see text] gaps.

Gas discharge and breakdown phenomena have become increasingly important for the development of an ever-growing number of applications. The need for compact and miniaturized systems within power, pulsed power, semiconductor, and power electronic industries has led to the imposing of significant operating electric field stresses on components, even within applications with low operating voltages. Consequently, the interest in gas discharge processes in sub-millimeter and microscale gaps has grown, as the understanding of their initiation and propagation is critical to the further optimization of these technologies.

An 8-year, single-centre experience of primary image-guided insertion of 'button' gastrostomy catheters: Technical and clinical results.

Introduction: 'Button' gastrostomy insertion is traditionally a two-step procedure with an initial longer gastrostomy tube inserted followed by placement of the shorter 'button' gastrostomy in 6 weeks when the track is mature. The aim of this study is to assess whether the placement of a Button gastrostomy de novo is a safe and effective method of radiologically inserted gastrostomy (RIG) insertion.

Methods: Using our Picture Archive and Communication System (PACS) and electronic patient charts we identified all patients who underwent primary 'button' gastrostomy over an 8-year period with at least a 1-year follow-up period.

MRTs Speak Up: The Professional Identity Crisis Brought on by COVID-19.

The purpose of this study is to share the lived experience of Canadian medical radiation technologists (MRTs) in relation to their mental health during the pandemic by exploring the causes and impacts of the COVID-19 pandemic on the professional group within the workplace. Data from eight semi-structured interviews and one focus group were conducted between April and June 2021. Audio files were transcribed and uploaded to a qualitative data analysis computer software program (NVivo) where codebook thematic analysis was conducted.
