In situ X-ray di¡raction studies of dense hydrous magnesium silicates at mantle conditions

Lizardite was pressurized up to about 28 and 20 GPa and heated at 1310 ( þ 50) and 1100 ( þ 100)3C; antigorite was pressurized at about 25 and 22 GPa and heated at V10003C, with a Nd:YAG laser using the double-side laser heating technique. Samples were then examined in situ by energy dispersive synchrotron X-ray diffraction. Our results show that phase E, superhydrous phase B, and phase D are i...

Studies on Digitalis VI

T IS undisputed that the administration of digitalis to patients with many forms of congestive heart failure results in an improvement in both the clinical state and in the abnormal circulatory dynamics that are characteristic of heart failure.'-6 The effects of digitalis in subjects without heart failure are less well defined. Although some glycosides augment the contractile force of nonfailin...

Part VI Example Problems

An object is cloaked if its presence cannot be detected by an observer using electromagnetic or other forms of imaging. In fact, the observer should not notice that cloaking is even occurring. Cloaking has a long history in science fiction, but recent developments have put the idea on a firmer mathematical and physical basis. Suppose that an observer seeks to image some bounded region Ω in spac...
