...using a fusion of physics and history, they were able to determine that garnets with which a French queen was laid to rest had Indian origins. The garnets were set in cloisonne, and French garnets rarely are set that way. Perin traced its origins and Calligaro employed particle induced x-ray emission, or PIXE, a technique that accelerates particles, to discern the elements in the different garnets by their movement. Because garnets of different elements are found in different locations, the researchers were able to conclude that they, indeed, were of Indian origin. In addition to the lecture series, McCormick...
...explosive cameo and other classic surprises prove highly accessible, many of the quips from the cast force him to do some serious mental gymnastics. In an attempt to digest this tougher humor, he asks lots of questions about SAT vocabulary and allusions to the likes of 1950s X-ray glasses constructed out of cardboard and a feather. He watches episodes five or six times, laughing progressively more at each new viewing. In addition to stretching his cerebrum, Peter and the gang inspire him to pack it with particularly knee-slapping scenes and to reenact them for anyone willing to listen...
...result, HUHS discontinued the Student Dental Plan at the start of last spring. HUHS contacted several major dental insurers to develop a substitute, but companies declined to bid on a plan for Harvard students. Instead, HUHS offered students a discount package of $180 for an annual exam, x-ray, and cleaning, and 10 percent savings on treatment at the Holyoke Center...
...lesions or plaques that block the arteries then show up on an X-ray picture called an angiogram. And if you don't consider catheterization real surgery, you don't understand how invasive and delicate an operation it actually is. The process can take anywhere from four to six hours and carries a 1% risk of serious complications, including death, from wayward catheters that can tear the delicate artery walls--which is why doctors don't order it lightly. Yet 20% to 40% of patients who take the risk turn out not to have needed it: they show no significant...
...until recently. The past 18 months have brought a wave of advances in cardiac imaging, leading many doctors to wonder whether it's time to change the way they diagnose and treat heart disease. Leading the way are improvements in CT (for computed tomography) scanning, which uses highly specialized X-ray machines to take multiple, finely layered pictures of the heart and surrounding blood vessels. Sophisticated computer programs sort the data to generate amazingly detailed, three-dimensional images like the ones that alerted Fackelmann's doctors to his hidden heart problem. Advances in other techniques like MRI (magnetic resonance imaging...
