The temporal characteristics of the polar wind were studied with both a full set of hydrodynamic equations and a simplified set of collisionless equations. The hydrodynamic set contained continuity, momentum and energy equations for H +, O+ and electrons, including collisional conductivities and variable, but isotropic, ion and electron temperatures. The collisionless model included the same sp...

Swift discovered GRB050128 with the Burst Alert Telescope and promptly pointed its narrow field instruments to monitor the afterglow. X–ray observations started 108 s after the trigger time. The early decay of the afterglow is relatively flat with a temporal decay modeled with a power law with index ∼ −0.3. A steepening occurs at later times (∼ 1500 s) with a power law index of ∼ −1.3. During t...

The ratio of the Bondi and Jeans lengths is used to develop a cloud-accretion model that describes both an inner Bondi-type regime where gas pressure is balanced by the gravity of a central star and an outer Jeans-type regime where gas pressure is balanced by gas self-gravity. The gas density profile provided by this model makes a smooth transition from a wind-type inner solution to a Bonnor-Eb...

AIM Clinical supervisors are appointed to ensure that medical trainees receive a satisfactory education, improve their academic orientation and develop professional attitudes. The aim of this study was to find out, from the paediatric trainee's perspective, how their clinical supervisor could best do that. METHODS We conducted in-depth interviews with seven paediatric trainees in a university...

PURPOSE To provide a model for assessing occupational therapy workforce needs by using a demand-based approach to determine current workforce status in the Northwest region. Regional information may have implications for addressing national occupational therapy service needs. METHOD A questionnaire was sent to a proportional random sample of 234 facilities that hire occupational therapy pract...

Health reform promotes the delivery of patient-centered care. Occupational therapy's rich history of client-centered theory and practice provides an opportunity for the profession to participate in the evolving discussion about how best to provide care that is truly patient centered. However, the growing emphasis on patient-centered care also poses challenges to occupational therapy's perspecti...

OBJECTIVE In addition to the need for good measurement tools in occupational therapy, there is a need for the tools to be used knowledgeably. The purpose of this article is to investigate the usefulness of the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP) for both descriptive (diagnostic) and evaluative (change over time) purposes. METHOD The typical profile of subtest scores for chil...

The profession of occupational therapy has been defined as follows: Occupational therapy is the art and science of directing man's participation in selected tasks to restore, reinforce and enhance performance, facilitate learning of those skills and functions essential for adaptation and productivity, diminish or correct pathology, and to promote and maintain health. Reference to occupation in ...

A review of recent and historical work in the field of transonic and supersonic ground effect aerodynamics has been conducted, focussing on applied research on wings and aircraft, present and future ground transportation, projectiles, rocket sleds and other related bodies which travel in close ground proximity in the compressible regime. Methods for ground testing are described and evaluated, n...

The flow structure of strongly turbulent Taylor-Couette flow with Reynolds numbers up to Re(i)=2×10(6) of the inner cylinder is experimentally examined with high-speed particle image velocimetry (PIV). The wind Reynolds numbers Re(w) of the turbulent Taylor-vortex flow is found to scale as Re(w)∝Ta(1/2), exactly as predicted by Grossmann and Lohse [Phys. Fluids 23, 045108 (2011).] for the ultim...
