Abstract: In order to develop and optimize metering strategies for fed-batch fermentations in two or more reaction vessels, release systems containing nutrients are attached to the inner surfaces of the reaction vessels in areas that will come into contact with culture liquid placed in the vessels.

Abstract: A method of impregnating an e-PTFE (expanded polytetrafluoroethylene) foil with a biologically-active substance.

Abstract: The present invention describes a deposition method for applying an active ingredient onto an endoprosthesis with a thin polymer coating. By means of the inventive deposition method which can be carried out in a technically easy way it is possible to bring about a slow and largely constant active ingredient release, as shown in III. 1 using tretinoin as the example. Since further processing steps are not necessary after the application of the active ingredient(s), no destruction of the active ingredient by the application of a second polymer coating, for example, has to be feared. Thus, relatively unstable active ingredients, such as tretinoin, can also be applied onto the endoprosthesis without any problems.

Abstract: The invention relates to polymer-coated stents, processes for their production and their use for restenosis prevention.

Abstract: A railway wheel/rail squeal suppression, wheel/rail noise reduction and wear reduction arrangement includes a separate structure (14) carried by a rail. The separate structure has a saddle-like profile including a web portion (15) defining a running surface for supporting the wheel, and two flange portions (16a, 16b). The saddle-like profile is shaped substantially in conformity with the shape of the railhead, is located on top it and is mechanically de-coupled therefrom. Resilient means (17) is interposed between the web portion and the railhead (13). The web portion (15) has a thickness not less than about twice the thickness of the flange portions so as to resist detrimental compression of the resilient means (17) and transfer only a portion of wheel load to the rail, and the flange portions (16a, 16b) are connected to the rail so as to transfer a remaining wheel load thereto.

Abstract: A hydrophilic coating on a polymeric substrate is prepared by subjecting at least one hydrophilic vinyl monomer to radiation-induced graft polymerization on an activated substrate surface.
