Infrared diffuse interstellar bands in the Galactic Centre region.

The spectrum of any star viewed through a sufficient quantity of diffuse interstellar material reveals a number of absorption features collectively called 'diffuse interstellar bands' (DIBs). The first DIBs were reported about 90  years ago, and currently well over 500 are known. None of them has been convincingly identified with any specific element or molecule, although recent studies suggest that the DIB carriers are polyatomic molecules containing carbon.

Satisfaction with primary health care and confidence in general practitioners: an exploratory comparison of US and UK students.

This paper explores attitudes of university students towards two differently organised health services, ie the National Health Service in the UK and the more market oriented system in the US and analyses the level of confidence placed in primary care providers (GPs/family physicians) in both systems. Although major differences in the perception of the two health care systems are identified, hardly any differences emerge between the two countries in terms of the confidence patients place in their primary care providers.
