Abstract: (Rigid) foams can be produced by heating a blowing agent containing polymers through the combination of thermal energy with irradiation by microwaves.

Abstract: The invention relates to modified G-protein coupled receptors (GPCRs) which (i) have decreased responsiveness to an endogenous activating ligand, and (ii) may be activated by exogenous agonists, which may be relatively benign over the counter drugs such as antihistamines. The modifications comprise mutations at particular amino acid positions, relative to the unmodified GPCRs. The invention also provides methods of use comprising administration of the modified GPCRs, for example in treating a neurological circuit disorder.

Abstract: A production process can produce foam materials from a polymer composition. This production process may involve preheating a polymer composition to be foamed. The preheated composition may then be foamed by a thermal process assisted by microwaves. The foaming may occur in an apparatus that has a heating device. The polymer composition may contain a blowing agent.

Abstract: A sensor unit for a penetrating connection to an installation wall of a hygiene-critical technical installation. The sensor unit has a passage end located inside a hygiene area of the technical installation when in use, a hygiene cover for the passage end, and a connecting device for force-locking connection between hygiene cover and installation wall. The connecting device has an external thread on the sensor unit, at least one union nut, and an internal thread on a cover interior of the hygiene cover. The cover interior is formed by a closed-surface, circular front wall and a closed circumferential wall extending axially therefrom. The circumferential wall at its end axially opposite to the front wall has a connecting surface with an axial seal for abutment against the installation wall.

Abstract: A production process can produce foam materials from polymer compositions. This process involves preheating in the foaming of polymers containing blowing agents and subsequent foaming by a thermal process assisted by microwaves.
