Abstract: A dental retractor including: right, left, upper and lower flanges extending around a retractor opening and intended to rest, in a service position, on the right labial commissure, the left labial commissure, the central part of the upper lip and the central part of the lower lip respectively, of a user. The retractor including: a structure on which the flanges are attached. The retractor including: right and left handles rigidly attached to the right and left ends of the structure respectively, and/or to the right and left flanges respectively, shaped so as to extend outside the mouth of the user in the service position. The structure and/or the attachment of the flanges on the structure is/are shaped so that the horizontal closing force required to bring the right flange and the left flange 10 mm closer together is greater than 5 N.

Abstract: A method for transferring a piezoelectric layer from a donor substrate onto a support substrate comprises the steps of: a) providing a predetermined splitting area in a piezoelectric donor substrate, b) attaching the piezoelectric donor substrate to a support substrate to form an assembly, and c) detaching the piezoelectric layer from the piezoelectric donor substrate comprising applying an electric field. By using the electric field, the detachment step can be carried out at low temperatures. A detaching chamber for carrying out at least a portion of such a method includes one or two chucks comprising first and/or second electrodes for applying an electric field to a piezoelectric layer.

Abstract: A process for transferring a thin layer consisting of a first material to a support substrate consisting of a second material having a different thermal expansion coefficient, comprises providing a donor substrate composed of an assembly of a thick layer formed of the first material and of a handle substrate having a thermal expansion coefficient similar to that of the support substrate, and the donor substrate having a main face on the side of the thick laver; introducing light species into the thick layer to generate a plane of weakness therein and to define the thin layer between the plane of weakness and the main face of the donor substrate; assembling the main face of the donor substrate with a face of the support substrate; and detachment of the thin layer at the plane of weakness, the detachment comprising application of a heat treatment.

Abstract: A system and method for automated securities trading is provided. The system includes a lead trader account database, a follower account database, and a trade determination system. Trade information is received from a lead trader and a listing of followers for the lead trader is retrieved from the lead account database. For each follower, their account at the follower account database is accessed to confirm that they desire to participate in the lead trader's trade and that they have enough funds to do so. The lead trader and follower's traders are then grouped together and traded as a single trade. The traded shares are then provided to the lead trader and followers at the average price of the trade.

Abstract: Aqueous liquid having an oxygen demand flows into a treatment vessel where it is treated by suspended aerobic bacterial solids in the presence of dissolved oxygen. A pressurised flow of the treated liquid passes to a clarifying membrane separator effective to separate the flow into a discharge stream of clear liquid and a pressurised recycle stream concentrated in the aerobic bacterial solids. A first oxic gas is employed to scour the membranes and is conveyed away from the membrane separator in the pressurised recycle stream. The pressurised recycle stream is returned to under the surface of the liquid in the treatment vessel. A second oxic gas is introduced either into the pressurised recycle stream or into a further pressurised stream of aqueous liquid flowing into the same volume. The rate of introduction of the oxic gases is controlled with reference to the pH and dissolved oxygen concentration of the liquid in the vessel.
