12C/13C ratio in ethane on titan and implications for methane's replenishment.

The (12)C/(13)C abundance ratio in ethane in the atmosphere of Titan has been measured at 822 cm(-1) from high spectral resolution ground-based observations. The value, 89(8), coincides with the telluric standard and also agrees with the ratio seen in the outer planets. It is almost identical to the result for ethane on Titan found by the composite infrared spectrometer (CIRS) on Cassini.

The healing path: A culture and community-derived indigenous therapy model.

In recent times, psychosocial intervention activities by Native/Aboriginal traditional healers have received much attention. There is a belief among many Native Americans and Aboriginal Canadians that their current problems are connected to past and contemporary traumas and that psychology as a profession has failed them and is even perceived as an agent of social control and hegemony. As a result, more and more Aboriginal people are turning to traditional ways for psychological healing.

Observations of CH4, C2H6, and C2H2 in the stratosphere of Jupiter.

We have performed high-resolution spectral observations at mid-infrared wavelengths of CH4 (8.14 micrometers), C2H6 (12.16 micrometers), and C2H2 (13.

Wavelength dependence of the scattering loss in fluoride optical fibers.

Scattering losses as low as 0.025 dB/km at 2.55 microm have been measured in short lengths of fluoride-glass optical fiber.
