An evolutionary continuum from nucleated dwarf galaxies to star clusters.

Systematic studies have revealed hundreds of ultra-compact dwarf galaxies (UCDs) in the nearby Universe. With half-light radii r of approximately 10-100 parsecs and stellar masses M≈ 10-10solar masses, UCDs are among the densest known stellar systems. Although similar in appearance to massive globular clusters, the detection of extended stellar envelopes, complex star formation histories, elevated mass-to-light ratio and supermassive black holes suggest that some UCDs are remnant nuclear star clusters of tidally stripped dwarf galaxies, or even ancient compact galaxies.

A SWOT analysis of the physiotherapy profession in Kuwait.

Background And Purpose: Since the end of the Gulf War in 1991, Kuwait has become one of the wealthiest countries in the world and one that has a highly socialized health-care system. This rapid growth and socio-economic development appears to have had a negative impact on the health of its people. As such, the profession of physiotherapy may be in a unique position to address this issue by providing health behaviour interventions and promoting healthy lifestyles.
