Beta decay of Neutron-Rich 53-56Ca (2008)

Mantica, P. F., Broda, R., Crawford, H. L., Damaske, A., Fornal, B., Hecht, A. A., ...

Beta-decay properties of neutron-rich Ca isotopes have been obtained. Half-life values were determined for the first time for 54Ca [86(7) ms], 55Ca [22(2) ms], and 56Ca [11(2) ms]. The half-life of...

Nuclear Magnetic Moment of the 57Cu Ground State (2006)

Minamisono, K., Mantica, P. F., Mertzimekis, T. J., Davies, A. D., Hass, M., Pereira, J., ...

The nuclear magnetic moment of the ground state of 57Cu has been measured to be 2.00 +/- 0.05 nuclear magnetons (nm) using the beta-NMR technique. Together with the known magnetic moment of the...

Detection of severity of coronary artery disease by the ST segment/heart rate relationship in patients on beta-blocker therapy (1982)

KARDASH, M, BOYLE, R, ELAMIN, M S, STOKER, J B, LINDEN, R J

Many patients presenting with anginal pain are on beta-blocker therapy and it has been suggested that noninvasive exercise tests for coronary artery disease are adversely affected by such therapy....

The slope of ST segment/heart rate relationship during exercise in the prediction of severity of coronary artery disease (1982)

KARDASH, M., ELAMIN, M. S., WHITAKER, W., SMITH, D. R., BOYLE, R., ...

The results of a new excercise electrocardiography test were compared with those of coronary arteriography in 120 patients. Thirty patients were under beta-blocker therapy and 90 patients were not....
