The first Dounreay hot particle (hereafter 'Particle') to be formally identified was recovered from the Dounreay foreshore in 1983. A further single Particle was recovered from Sandside beach the following year. Particles have been detected and removed from the Dounreay foreshore regularly since 1984 and from the offshore sediments since 1997. Since 1997, an extensive research and development p...

An outstanding problem in gravitation theory and relativistic astrophysics today is to understand the final outcome of an endless gravitational collapse. Such a continual collapse would take place when stars more massive than few times the mass of the sun collapse under their own gravity on exhausting their nuclear fuel. According to the general theory of relativity, this results either in a bl...

It is hard to believe that, with the arrival of 2015, Biology Open (BiO) begins its fourth year of publication.

They occur in a variety of modern applications including the Web where blogs, feeds, and microblogs are increasingly adopted to distribute and present information in real-time streams. We foresee the need for languages, tools and methodologies for representing, managing and reasoning on data streams for the Semantic W...
