Atherosclerosis of the aorta is a well-known risk factor for peri-operative complications in patients undergoing cardiac surgery. Coronary and peripheral artery bypass procedures can be challenging when the native aorta is not amenable to bypass grafting due to severe calcification. We describe the successful management of a patient who underwent ascending aorta replacement with concomitant three-vessel coronary artery bypass, bilateral aorto-axillary bypass and left axillary-to-carotid bypass.

Demand for radiologic technologists in the United States greatly outstripped supply throughout the late 1990s and peaked in 2000, when vacancy rates for radiologic technologists reached an average of 18% nationwide. To combat the shortage, the ACR and the American Society of Radiologic Technologists (ASRT) launched a series of aggressive recruitment and retention initiatives designed to boost the number of technologists. The campaigns have resulted in rising enrollments in educational programs, greater numbers of graduates and new technologists, and the expansion of the career ladder.

ACR and ASRT joined forces to address the workforce shortages of radiologists and radiological technologists with the development of a radiologist assistant. This paper discusses the rationale for the evolution and development of the radiologist assistant as designed by ACR and ASRT. With the profession of radiology experiencing workforce shortages among radiologists and radiological technologists many radiological groups were beginning to hire ancillary personnel to fill efficiency gaps in practices.

We have created two sheets of approximately 1 K phonons in liquid (4)He at approximately 55 mK such that they intersect each other as they move towards a common point. If the two sheets have a small angle between them, they interact strongly and create a hot line in the liquid helium. This line is continuously fed with energy from the two sheets and loses energy by creating high-energy phonons.
