A vent apparatus is adapted to be mounted in an aperture formed in a fuel tank. The vent apparatus includes a vent controller sized to extend through the fuel tank aperture and an outer cover coupled to the vent controller and welded to the fuel tank to support the vent controller in the fuel tank aperture.

The present invention relates to a method of screening compounds for modulation and binding to proteins, in particular proteins that have been immobilized in a monolithic chromatographic stationary phase. The method involves observing the conversion of a substrate to product by the protein and determining a product to substrate ratio. Changes in this ratio in the presence of another compound indicates that the other compound is a modulator of the enzyme. Various applications of this method to compound screening, including high throughput screening formats, are described.
摘要:
A control instrument for a system for generating acoustic output which includes a processor for receiving user input signals and control the acoustic output in response to the user input signals. The control instrument includes an instrument body, and at least one sensor element carried by the instrument body. The sensor element generates user input signals upon tactile actuation of the sensor element by a user. The user input signals indicate the location of contact and amount of force applied to the sensor element by the user. A music synthesis system and a sound processing system each including the control instrument are also provided.

A video of a virtual world is created utilizing stored gameplay data and game states. The gameplay data is used to re-create a given gameplay sequence in order to create video of the gameplay sequence. The gameplay sequence may be re-created using enhanced graphics to create new video files from any number of visual perspectives.

摘要:
The invention relates to the preparation of monolithic silica under mild conditions from alkoxysilanes derived from sugars, sugar acids, sugar alcohols and polysaccharides including glycerol, sorbitol, mannose and dextran. Unlike the commonly used silica starting material TEOS (Si(OEt)4), the sol-gel hydrolysis and cure of the sugar derivatives are not very sensitive to pH as similar rates of gelation were observed over a pH range of about 5.5-11. The morphology of the resulting silicas could be varied using specific additives, including multivalent ions and hydrophilic polymers.
摘要:
The present invention relates to methods of immobilizing membrane-associated molecules within a sol-gel matrix. The membrane-associated molecule is embedded in the bilayer of a liposome. The molecule-liposome assembly remains functionally intact when it is immobilized within a protein and membrane-compatible sol-gel derived from polyol silane precursors or sodium silicate. The activity and stability of the entrapped membrane-associated molecule was significantly improved in macroporous silica.
