Abstract: The present invention relates to process for producing ?-carotene in a specific solvent.

Abstract: A manhole cover for manholes, sewer accesses or drainage channels, including a reinforcing element and a body made of plastic which is connected to the reinforcing element. The reinforcing element may be constructed from intersecting, vertically aligned elements. Corrugations may be formed in the reinforcing element. The reinforcing elements may be arched and may include an outer encircling strip and a central plate, which are each connected to the body made of plastic. The reinforcing element rests on a bearing surface on the manhole, sewer access or drainage channel when the manhole, sewer access or drainage channel is closed by means of the manhole cover. The body made of plastic includes ribs, which extend perpendicularly or at an angle of more than 45° to the surface surrounding the manhole cover, sewer access or drainage channel when the manhole, sewer or drainage channel is closed.

Abstract: Enhanced search system and method based on entity ranking that accepts votes for online and offline users and calculates rankings for user attributes that are used to provide highly valued search results. An input is received from a user indicating an opinion of another user or plurality of other users. In one embodiment, reputation scores are weighted by the reputation scores of voters. In another embodiment, weights are derived from voter reputation scores in the domain in which the voting took place. In another embodiment, reputation scores are adjusted according to a plurality of factors, including, but not limited to, user demographics or user behavior.

Abstract: The invention relates to a method which allows a long-term bonding of thermoplastics. The air-plasma treatment at atmospheric ambient pressure allows very long storage times, up to several years. The inventive method allows to glue thermoplastics, stored under various storage conditions, for a long term without any noticeable decrease in adhesive strength.
