Abstract: The invention relates to a method and a device for producing biogas in a combined fermenter, in the first section (2) of which organic material is produced by phototrophic microorganisms (1) using atmospheric carbon dioxide and oxygen, said organic material being used to produce biomethane by means of methanogens (5) in a second section (4). The fermenter is operated in multiple modes and using special gassing and degassing methods such that an optimal gas supply corresponding to the requirements of the respective microorganisms and preferably also the absorption or the use of atmospheric carbon dioxide is ensured.

Abstract: The present invention provides resin infused composite articles. Also provided is a method for preparing the composite articles of the invention.

Abstract: A method, apparatus, and medium are provided for identifying files. Files are received from various sources, and a statistical distribution is generated for data contained in each file. The statistical distribution is compared to model distributions that are representative of known files or file types. Based on the comparison, file types can be verified or detected. Known file types can also be used to generate representative statistical distributions for the type. The invention can also detect malicious programs such as viruses or worms, and generate signatures that can be used to filter such programs.
