A Virtual Veterinary Emergency Clinic – investigation of students' perceptions and self-efficacy beliefs

At the University of Copenhagen, companion animal emergency medicine is taught in a clinical environment after students’ completion of basic theoretical and clinical courses. Students are often anxious about emergency shift partici-pation and the prospect of being the responsible veterinarian in emergency sit-uations. This study aimed to investigate whether inclusion of virtual patients in addition to real-life patients would increase students’ perceived self-efficacy in emergency medicine. Sixty-seven students were divided into two groups, one of which participated in regular emergency rotations, while the other also learned in a Virtual Emergency Clinic (VEC). Participating students were given a ques-tionnaire regarding course experience and self-efficacy, with responses on a 10-point Likert scale. The VEC group expressed a higher level of knowledge and sig-nificantly higher level of exposure to and ability to handle emergency patients. In addition, virtual problem-based learning appeared to increase veterinary students’ self-efficacy with regard to managing emergency patients in their fu-ture careers

Design of the advanced divertor pump cryogenic system for DIII-D

The design of the cryogenic system for the D3-D advanced divertor cryocondensation pump is presented. The advanced divertor incorporates a baffle chamber and bias ring located near the bottom of the D3-D vacuum vessel. A 50,000 l/s cryocondensation pump will be installed underneath the baffle for plasma particle exhaust. The pump consists of a liquid helium cooled tube operating at 4.3{degrees}K and a liquid nitrogen cooled radiation shield. Liquid helium is fed by forced flow through the cryopump. Compressed helium gas flowing through the high pressure side of a heat exchanger is regeneratively cooled by the two-phase helium leaving the pump. The cooled high pressure gaseous helium is than liquefied by a Joule-Thomson expansion valve. The liquid is returned to a storage dewar. The liquid nitrogen for the radiation shield is supplied by forced flow from a bulk storage system. Control of the cryogenic system is accomplished by a programmable logic controller

Thermal Hydraulic Behavior of the First ITER CS Module

The ITER Central Solenoid (CS) modules are under fabrication by the US ITER organization and its subcontractors. US ITER will supply seven modules to the ITER Organization (IO), six of which will be assembled in a stack that forms the ITER Central Solenoid, the last one being spare. The first module, namely CSM 1 was manufactured by General Atomics (GA) and went through Factory Acceptance Tests (FAT) including high voltage testing, Paschen testing and then cold test at 4.5 K and up to 40.0 kA in order to demonstrate compliance with coil performance requirements. The paper focuses on the results of the first CS Module thermal hydraulic characterization without current (and field). Pressure drops, transit time, and thermal coupling between pancakes are presented. Analysis results and tests are also compared
