Abstract: An aircraft includes a fuselage that provides an aircraft passenger cell and a plastically deformable protective body secured on the fuselage. The plastically deformable protective body can be secured on the bottom of the fuselage and/or laterally on the fuselage. The plastically deformable protective body can be secured releasably on the fuselage, for example, via a screw connection.

Abstract: The invention relates to a membrane having a pore-free separating layer including a polymer mixture for separating simple alcohols and water from their mixtures with other organic fluids by means of pervaporation or vapor permeation. In accordance with the invention, the polymer mixture is composed of at least two polymer components which are taken from the group of polymer components which includes of the following polymer components: Polyvinyl alcohol, other polymers such as poly N—N-dimethylaminoethyl methacrylate (poly DMAEMA), a copolymer of DMAEMA and N-vinyl pyrrolidone (NVP) or of DMAEMA and N-vinyl caprolactam (NVCL), a terpolymer of DMAE, NVP and NVCL or of vinyl acetate ethylene vinyl chloride or from vinyl chloride ethylene acrylic ester or from vinyl acetate vinyl chloride acrylic ester. The invention further relates to the use and to a method for manufacturing a membrane in accordance with the invention.

Abstract: The present invention relates to synthetic lipoteicoic acid (LTA) mimetics which are useful as vaccine components for therapy and/or prophylaxis of bacterial infection.

Abstract: A method is disclosed for treating residues from biodiesel production for the isolation of highly pure potassium sulphate from potassium sulphate-containing sludge. First, potassium sulphate-containing sludge from biodiesel production is heated in the first stage under non-oxidizing conditions to a material temperature between 400 and 700° C.; in a second stage the product from the first stage is heated under oxidizing conditions to material temperatures between 700 and 900° C.

Abstract: In a process for removing water by pervaporation or vapor permeation from mixtures with alcohols and/or carboxylic acids and/or carboxylic esters by bringing the mixture into contact with one side of a membrane and removing the water-containing permeate in vapor form from the other side of the membrane, the membrane used has been obtained by plasma polymerization.
