This study brought to light several factors influencing the return to work of workers with common mental disorders. Most of the supervisors interviewed were very open to finding ways to facilitate the return to work of these workers, but felt that the interventions used should take both their perspective and the constraints they face in the workplace into account. Subsequent studies on return to work should therefore focus equally on the individual and the workplace to ensure that the actions taken can be appropriately implemented and well received by all stakeholders, including supervisors, who are continually involved in front-line interventions.

A variational method called the local potential is used to find an approximate solution of the laminar boundary-layer flow of a pseudoplastic fluid past a flat plate. The so-called power-law model relates the stress tensor to the rate-of-deformation tensor. The results of the variational approach are obtained in an analytical form and are found to agree well with the exact numerical solution.

Boundary-layer equations have been used to obtain an exact solution for the free outflow of a non-Newtonian pseudoplastic fluid from a two-dimensional orifice into a mass of the same fluid. Existence of similarity solutions has been proved. The results obtained by Schlichting for the Newtonian fluid flow is shown to be the special case of the more general analysis given here. Though further effort is necessary to investigate the turbulent jet flow, the analysis presented here should make a definite contribution in this definition.
