RESUMO
The rotational distributions of H2 and HD formed on a highly oriented pyrolitic graphite surface at temperatures of 15-50 K have been measured using laser spectroscopy. The population of the rovibrational levels nu=1, J=0-4 and nu=2, J=0-4 has been observed and the average rotational temperatures of the nascent H2 and HD molecules have been determined. We find that the average rotational temperature of the newly formed molecules is much higher than the surface temperature on which they have formed. We compare our results with other recent experimental data and theoretical calculations.
RESUMO
This study examines the safety and efficacy of transthoracic echocardiographic (TTE) guidance of atrial septal defect (ASD) device closure. We evaluated 74 patients for TTE-guided ASD closure. Fifty-six patients had successful device implantation using TTE guidance. Twelve patients were referred for surgical ASD closure on the basis of TTE evaluation. Five patients with multiple ASDs or poor transthoracic acoustic windows had ASD device closure guided by transesophageal echocardiography (TEE).

Twenty-eight four-year-old and 28 five- and six-year-old subjects were presented with either poor or rich recipients. The recipients were defined visually with a picture of the type of home they lived in and verbally with a brief story. All subjects were asked to share from 17 units of each of two types of candy, one of low and the other of high value. The subjects assigned poor recipients shared a significantly larger number of units than the subjects assigned rich recipients, and all subjects shared a significantly larger number of the low value items. The age and interaction effects were nonsignificant. The effect of the affluence of the recipient was interpreted in terms of the arousal of empathy.
