The evidence base for computerised cognitive behavioural therapy (CCBT) for common mental health problems has expanded rapidly in recent years. Reviews and meta-analyses have produced promising findings with regard to CCBT’s effectiveness and acceptability, but developing and supporting effective and sustainable models of CCBT service implementation remains a challenge. This paper considers CCB...

In the case of elastic interaction between dislocations and point defects, complex interaction mechanisms can appear, which involve simultaneously depinning-repinning processes and dragging processes.

We consider the fractional drag in a double layer system of two-dimensional electrons in the half-filled lowest Landau level. At sufficiently large interlayer separations the drag is dominated by exchange of acoustic phonons and exhibits novel temperature and inter-layer distance dependences. At low temperatures the phonon mediated drag is strongly enhanced with respect to the case of zero magn...

Cf = skin friction coefficient CD = drag coefficient CDf = friction drag coefficient CDp = pressure drag coefficient h = step height M0 = freestream Mach number Patm = atmospheric pressure Pi = stagnation pressure Re = freestream Reynolds number Ti = stagnation temperature U = velocity U = normalized velocity Uτ = friction velocity X = longitudinal coordinate Z = vertical coordinate Z = normali...

The Cumulative Drag Index defined recently by Prasanna [1] has been generalised to include the centrifugal acceleration. We have studied the behaviour of the drag index in the Kerr metric as well as in the linearized Kerr and its Newtonian approximations. This analysis suggests that the drag index characterises an intrinsic property of spacetime with rotation. PACS: 04.20.Cv, 04.20.Ex, 04.40.Dg

The orographic gravity wave drag produced in flow over an axisymmetric mountain when both vertical wind shear and non-hydrostatic effects are important was calculated using a semi-analytical two-layer linear model, including unidirectional or directional constant wind shear in a layer near the surface, above which the wind is constant. The drag behaviour is determined by partial wave reflection...

For prawn trawling systems, drag reduction is a high priority as the trawling process is energy intensive. Large benefits have occurred through the use of multiple-net rigs and thin twine in the netting. An additional positive effect of these successful twine-area reduction strategies is the reduced amount of otter board area required to spread the trawl systems, which leads to further drag red...

Drag performance has entered mainstream British culture and is gaining unprecedented appreciation recognition, yet no sociological accounts of this transformation exist. Using an inductive analysis in-depth interviews with 25 drag performers, alongside netnography media other public data, article develops a understanding the mainstreaming drag. There are two clear reasons for success First, the...

Drag-and-guess is an extension of drag-and-drop that uses predictions which is based on application specific knowledge. As the user begins to drag an object, the system predicts the drop target and presents the result to the user. When the target is hidden in a closed folder or beneath other windows, the system makes it temporarily visible. This frees users from manual preparation such as expan...
