Evaluation of Includem’s intensive support services – September 2007
In 2005 Includem commissioned a two-year evaluation of its intensive support services provided to young people as part of the Intensive Support and Monitoring Service in Edinburgh, Glasgow, Dundee, East Dunbartonshire, and West Dunbartonshire. Over two years Includem’s provided intensive support, normally around 15 hours per week plus access to Includem’s 24-hour crisis helpline, to over 200 young people, including 69 young people with a Movement Restriction Condition ('electronic tag')

A Better Definition of the Kilogram
Fixing the value of Avogadro's constant, the number of atoms in 12 grams of
carbon-12, at exactly 84446886^3 would imply that one gram is the mass of
exactly 18x14074481^3 carbon-12 atoms. This new definition of the gram, and
thereby also the kilogram, is precise, elegant and unchanging in time, unlike
the current 118-year-old artifact kilogram in Paris and the proposed
experimental definitions of the kilogram using man-made silicon spheres or the
watt balance apparatus.Comment: 3 page
The effect of magnetic islands on ITG turbulence driven transport
In this work, we address the question of the influence of magnetic islands on
the perpendicular transport due to steady-state ITG turbulence on the energy
transport time scale. We demonstrate that turbulence can cross the separatrix
and enhance the perpendicular transport across magnetic islands. As the
perpendicular transport in the interior of the island sets the critical island
size needed for growth of neoclassical tearing modes, this increased transport
leads to a critical island size larger than that predicted from considering
collisional conductivities, but smaller than that using anomalous effective
conductivities.
We find that on Bohm time scales, the turbulence is able to re-establish the
temperature gradient across the island for islands widths , the turbulence correlation length. The reduction in the island
flattening is estimated by comparison with simulations retaining only the
perpendicular temperature and no turbulence. At intermediate island widths,
comparable to , turbulence is able to maintain finite
temperature gradients across the island
