    摘要： Method of assembling a first thin part to be welded made of copper (1) and a second thin part to be welded made of aluminium (2) using heterogeneous welding, the said method comprising a step that involves placing the ends of the said parts (1, 2) that are to be assembled so that they face one another and in pressing the said ends against one another so as to constitute a welding zone (3) extending along a welding zone (or line) between the parts (1, 2); and in applying an aluminium alloy by way of filler metal to the said welding zone (3) using a low energy welding method in which the electric arc (4) and the meltable filler wire (5) are wider than the combined thickness of the parts (1, 2), the said parts (1, 2) being held in such a way as to maintain the welding zone at the top using a fixing means comprising at least two rigid blocks (6a, 6b) of a conductive material the thickness of which is comprised between 1 and 2 mm, the length of which is greater than that of the parts to be welded (1, 2) and the width of which is sufficient to hold the said parts (1, 2), and a pressure fixing system allowing the blocks (6a, 6b) to be held against the parts (1, 2).

    摘要： Bone regeneration membrane (1) comprising:
    - a dense layer (2) made of resorbable polymer, said dense layer (2) having first and second opposite surfaces and being adapted to form a barrier to cells and soft tissues,
    - a nanofibrillar layer (3) made of resorbable polymer and attached to the first surface of the dense layer (2), said nanofibrillar layer comprising fibers having a diameter of nanometer size, said fibers being interlaced so as to present an average pore size greater than 10 µm to allow cell permeability and bone tissue regeneration.
