IMPORTANCE Surveyed physicians tend to place responsibility for high medical costs more on "demanding patients" than themselves. However, there are few data about the frequency of demanding patients, clinical appropriateness of their demands, and clinicians' compliance with them. OBJECTIVE To assess how frequently patients demand or request medical tests or treatments, what types they demand,...

Uncultured tumor-infiltrated spleen cells (TISpC) from mice bearing large (20-22 mm) s.c. MOPC-315 plasmacytomas were previously shown to be ineffective in bringing about the cure of mice bearing a nonpalpable (Day 4) tumor that had been treated with a subcurative dose (10 mg/kg) of cyclophosphamide (i.e., adoptive chemoimmunotherapy, ACIT) (M. B. Mokyr, J. C. D. Hengst, and S. Dray, Cancer Res...

We present observations taken with the Short Wavelength Spectrometer (SWS) on board the Infrared Space Observatory (ISO) of three evolved C-rich stars, the post-AGB star HR 4049 and two planetary nebulae, IRAS21282+5050 and NGC 7027. The spectra are dominated by the well-known infrared emission bands, attributed to Polycyclic Aromatic Hydrocarbons (PAHs). The SWS spectra for the first time allo...

We have obtained high-resolution images of two carbon-rich objects that are undergoing the transition from post-AGB star to planetary nebula: IRAS 21282+5050 (hereafter IRAS 21282), a young planetary nebula, and AFGL 3068, a post-AGB star with a high mass-loss rate. Detailed structure is seen in IRAS 21282. A torus of dust, with its polar axis in the N-S direction, surrounds the central star, i...

This paper reports on the status and design of the operational remotely operated vehicle Victor 6000, rated for 6000 m depth and of the 3000 m depth autonomous underwater vehicle Asterxx operated by Ifremer the French Institute for Sea Exploitation. Victor 6000 is part of a global system built of subsystems, scientific modules, winch and cable, dead weight and umbilical, positioning subsystem u...
