Abstract: The present invention provides improved variants of T7 RNA polymerase by introducing novel mutations which lead to improved thermostability of the enzyme. According to the invention, amino acid substitutions at the positions Val426, Ser633, Val650, Thr654, Ala702, Val795, and combinations thereof are advantageous.

Abstract: A gas sensor is for determining at least one physical quantity of a gas, e.g., an exhaust gas of an internal combustion engine, the gas sensor having a sensor element that is fixed in a housing of the gas sensor by a seal assembly. The seal assembly includes a sealing element, which has a ceramic and/or a metallic material. After the heat treatment, the sealing element has a maximum decrease in volume of 5 percent, or an increase in volume, based on the volume of the sealing element prior to the heat treatment.

Abstract: The design and attachment of an insulation package near the fuselage structure to protect the cabin region of an aircraft against fire acting on the insulation package from outside the aircraft environment, thus clearly facilitating evacuation of the passengers from the vehicle. The insulation package arrangement may comprise several fuselage insulation packages of an elongated form. These packages may adjoin the aircraft fuselage structure in the direction of the longitudinal axis of the aircraft. They may be completely enclosed by a burn-through-proof foil which is arranged in a space enclosed by interior paneling and by the panels of the outer skin.

Abstract: When a fire breaks out, air flows that promote the spread of fire may occur in the region between the load bay and the skin of the aircraft. According to one embodiment of the present invention, a fire barrier is disclosed that allows rapid decompression of the passenger cabin in the normal operating mode of the aircraft and prevents flashovers in case of a fire. In this case, the fire barrier may be arranged at different positions in the intermediate wall space of the aircraft.

Abstract: The present invention relates to the production of a variant of recombinant trypsin with increased substrate specificity for arginine versus lysine in non-animal host organisms. Moreover, the present invention relates to a variant of recombinant trypsin and their production. Also provided are use of recombinant porcine pancreatic trypsin variants for cleavage of precursors of insulins, and kits containing the variant of trypsin.

Abstract: The invention relates to an aircraft fuselage (12) comprising at least one space arranged in the aircraft fuselage and at least one wall (16). According to the invention, the wall resists burnthrough for a period of at least four minutes from outside the aircraft fuselage towards the space, wherein the region of the aircraft fuselage (12) underneath the space does not comprise burnthrough-resistant insulation. The space can be a cargo compartment of the aircraft or a passenger cabin, while the wall can be designed as a cargo compartment floor, passenger cabin floor or wing/fuselage fairing (belly-fairing). The design, according to the invention, of the aircraft fuselage results in burnthrough resistance that meets the requirements of FAR §25.856 (b) without any additional burnthrough-resistant insulation in the aircraft fuselage.

Abstract: The invention pertains to an insulation structure for thermally and acoustically insulating an aircraft that features at least one heavy layer, wherein the insulation structure according to the invention is characterized in that the insulation structure comprises an additional absorption layer, in that the heavy layer is perforated at least in certain areas, and in that the perforated area ratio of the heavy layer is adapted in such a way that the heavy layer is essentially transparent to sound for frequencies below a double-wall frequency of the insulation structure. This makes it possible to dampen sound with low frequencies below the double-wall frequency as effectively as possible.

Abstract: The present invention relates to an insulation structure for the internal insulation of a vehicle. The insulation structure is improved in such a way that using it a fire incursion of the flames of a source of fire acting from outside the vehicle environment into the vehicle interior is excluded as much as possible, an increase of the fire protection safety for separate interior regions lying proximal to a structure external skin being implemented by the type of the film insulation of the insulation package. The insulation structure comprises an insulation package (3), in which an insulation core (1) is embedded, and a film (11). The insulation package (3) is positioned inside an intermediate space which encloses internal paneling and an external skin. It is completely enclosed by the film (11). The film (11) is implemented using a burn-through safe film material, which is an obstruction to a flaming fire, to which a film surface region of this film is subjected during an occurring fire catastrophe.

Abstract: Use of at least one agent chosen from cyclodextrins and the derivatives thereof as a pearlescent agent, in a composition, for example, a pearlescent cosmetic composition, comprising a physiologically acceptable aqueous medium. Use of at least one agent chosen from cyclodextrins and the derivatives thereof and at least one surfactant in compositions. Pearlescent compositions comprising, a physiologically acceptable aqueous medium, at least one agent chosen from cyclodextrins and the derivatives thereof, at least one surfactant, and at least one conditioning agent; as well as use of at least one agent chosen from cyclodextrins and the derivatives thereof as an agent for suspending an insoluble conditioning agent; wherein the compositions disclosed herein may be used in a form chosen, for example, from rinse-out products, for example, for washing and/or conditioning a keratinous material.

Abstract: An insulation package is provided for insulating a cabin of a vehicle that includes, but is not limited to at least one wrapping foil and at least one core layer of an insulation material. The wrapping foil envelopes the core layer at least in some regions and includes, but is not limited to at least one opening for feeding-through a holding element. On the wrapping foil a fastening element is arranged that is designed to establish a mechanical connection with the holding element fed through the opening. This can be a positive-locking or a non-positive-locking connection. By integrating the fastening element in the insulation package, the expenditure for separate fasteners can be saved so that the installation time and the different components can be reduced.

Abstract: The present invention provides an aqueous composition comprising a protein with enzymatic activity of alpha-galactosidase. The present invention further provides a method of stabilizing an aqueous composition comprising a protein with enzymatic activity of alpha-galactosidase, and a method of preparing a purified aqueous composition comprising the protein with enzymatic activity of alpha-galactosidase.

Abstract: A filter element, in particular for filtering exhaust gases of an internal combustion engine, includes mutually parallel flow channels, at least two filter segments being provided which each have a subset of flow channels, the filter segments having a spacing from one another and being interconnected via connecting device(s) arranged integrally with the filter segments.
