Abstract: Provided are a method and system for efficiently producing a purified aqueous hydrogen peroxide solution having a high purity. This method for producing a purified aqueous hydrogen peroxide solution comprises: step A for vaporizing a raw material containing a crude aqueous hydrogen peroxide solution; step B for condensing at least a portion of the gas and liquid obtained in step A, and separating the gas and liquid into a gas phase and a liquid phase; and step C for returning, into the raw material, at least a portion of a separation liquid which is the separated liquid phase, wherein step C further includes step D for adjusting the concentration of hydrogen peroxide in the separation liquid.

Abstract: A brassiere is provided with a front piece containing two breast cups, with two side pieces, which can be connected together with a back closure, and with two shoulder straps which extend from the upper side edge of the breast cups to the back area of the side pieces. The breast cups are stiffened, especially in their lower and/or side areas. It is provided in accordance with the invention that for stiffening the breast cups in their side area at least one rod-shaped supporting element is arranged, which extends, for example, from the lower side edge of the breast cup at an angle upward to a point on the upper edge of the breast cup adjacent to an attachment of the shoulder strap.

Abstract: A thin-walled medical tubing comprising an elongated hollow tubular body which is open at both ends and extends continuously therebetween has a filler-containing resin layer in which the filler is oriented in a substantially circumferential direction with respect to the hollow tubular body. The tubing has excellent maneuverability, including pushability, ability to transmit torque, trackability and kink resistance, enabling it to be used as a sheath or catheter.
