Prominent ears--Pitanguy's island technique: long-term results.

Through the analysis of 300 cases of prominent ears operated by Pitanguy's technique with a follow-up of 1-15 years we observed the preservation of the aesthetic aspect as well as the cephaloauricular angle. We call attention to its easy performance and almost no incidence of early or late complications.

Characteristics of 3H-tifluadom binding in guinea-pig brain membranes.

3H-Tifluadom labels specifically recognition sites of opioid kappa receptors. Membranes of guinea-pig whole brain bind 3H-tifluadom with two affinities, in contrast to the cerebellum where almost all opioid sites are kappa.

Orelhas em abano - resultados a longo prazo tratados pela tecnica de Pitanguy. / Prominent ears - long term results treated by Pitanguy's technique

Na analise de 300 casos de orelhas em abano pela tecnica de Pitanguy com um follow-up de 1 a 15 anos, verificamos a preservacao do aspecto estetico e do angulo cefalo-auricular. Chamamos a atencao para a seguranca da tecnica, praticamente isenta de complicacoes imediatas e tardias

Observations of a probable change in the solar radius between 1715 and 1979.

Solar eclipses were observed from locations near both edges of the paths of totality in England in 1715, in Australia in 1976, and in North America in 1979. Analysis of these observations shows that the solar radius has contracted by 0.34 +/- 0.2 arc second in 264 years.

Lunar Gravity via Apollo 14 Doppler Radio Tracking.

Gravity measurements at high resolution were obtained over a 100-kilometer band from + 70 degrees to -70 degrees of longitude during the orbits of low periapsis altitude (approximately 16 kilometers). The line-of-sight accelerations are plotted on Aeronautical Chart and Information Center mercator charts (scale 1 : 1,000,000) as contours at 10-milligal intervals. Direct correlations between gravity variations and surface features are easily determined. Theophilus, Hipparchus, and Ptolemaeus are negative features, whereas Mare Nectaris is a large positive region. The acceleration profiles over Mare Nectaris are suggestive of a broad disk near the surface rather than a deeply buried spherical body. These data are in good agreement with the short arc of Apollo 12 lunar module descent data.

Lunar Gravity over Large Craters from Apollo 12 Tracking Data.

The Doppler residuals from the Apollo 12 lunar module radio tracking data indicate large negative accelerations over the craters Ptolemaeus and Albategnius. The mass deficienicies required to produce these accelerations are approximately equivalent to the removal of the surface material to a depth of 1 kilometer over the entire area of these craters. Several other features of the gravity fine structure can also be correlated with topography.

Nonexistence of large mascons at mare marginis and mare orientale.

The analysis of line-of-sight residual accelerations from Lunar Orbiters 3 and 5 does not show any evidence for large mascons near the lunar limbs. Although unfavorable geometry reduces the acceleration effect due to any mascon near the limb, simulations show that large masses at Mare Orientale and Mare Marginis would produce substantial accelerations, in complete disagreement with the actual Doppler tracking data obtained from a Lunar Orbiter experiment.

Mascons: lunar mass concentrations.

Lunar Orbiter tracking data have been processed to supply a qualitatively consistent gravimetric map of the lunar nearside. While a simplified model was employed, the results indicate that there are large mass concentrations under the lunar ringed maria. These mass concentrations may have important implications for the various theories regarding lunar history.
