In collaborative clinical learning field, several recent pertinent studies showed that gathering learners with their tutor still insufficient to improve students' learning quality and knowledge acquisition. Consequently, focusing attention on professional skills within a collaboration environment seems to be the most appropriate way to reach the wished learning objectives, particularly in a complex specialty such as medical diagnosis learning. In this paper, we firstly introduce the concept of medical diagnosis from cognitive studies view that have been performed in the field of medical education. Then, we will discuss our shared web environment designed to support distance diagnosis learning, which aims to promote knowledge coconstruction and collaboration between learner

The coupled finite element method - finite volume method are applied to solve magnetohydrodynamic (MHD) flow equations and the thermal equation in the linear induction MHD pump taking into account the saturation of the ferromagnetic materials. This study is done using the stream-vorticity formulation. The purpose of this paper is to represent the velocity and the temperature respectively in linear and non linear cases because it is required to have the knowledge of the flow and the temperature to design an MHD pump. Additionally, the effect of the electromagnetic thrust on the flow distribution in a linear induction MHD pump is studied.
