摘要:
The present invention relates to a method for determining the three dimensional structure of biomolecules, such as proteins, protein fragments, and peptides. The biomolecule is encapsulated in an amorphous silica matrix, from which a needle specimen is prepared. Atom probe tomography is then used to analyze the needle specimen and the data is used to reconstruct the three dimensional structure of the biomolecule. The present invention greatly facilitates determination of the three dimensional structure of biomolecules.

There is disclosed means for uploading/downloading images to/from a remote server and for viewing the same. The uploading/downloading of the images to/from the remote server is parallel instead of serial. This means that the images, instead of being transferred as a sequential stream of bytes, instead are arranged in scans of image data in such a way that the uploaded/downloaded images can be browsed early albeit at a lower quality than if the entire image data is considered. As in the serial case, it is possible to interrupt the uploading/downloading process at any time, and still browse the received image data. Likewise it is possible to re-start the uploading/downloading process in the future.

Use of a compound having a hydrophobic moiety attached to a hydrophilic moiety, wherein the hydrophilic moiety comprises a β-keto acid group and the hydrophobic moiety is attached via a bond from a carbon or an oxygen of the hydrophobic moiety to a carbon of the β-keto acid group, provided that the β-carbon of the β-keto acid group does not form part of a carboxyl or ester group, or a salt thereof, as a surfactant. A dispersion comprising said surfactant as a dispersing agent. A microemulsion comprising said surfactant. A method for breaking a dispersion comprising said surfactant as a dispersing agent, said method comprising the steps of a) providing said dispersion at a temperature where it is substantially stable; and b) setting the temperature of said dispersion, so as to achieve a desired decomposition rate of the surfactant. A method for reducing the surface tension between a liquid and another phase, comprising adding to the liquid said surfactant. Various applications making use of the surfactant properties of the compound. Use of an ester or amide of the compound as a surfactant precursor.
摘要:
A controlled slow down apparatus and method for use in the event that a light-duty combustion engine has entered a state of excessive speeds or auto-ignition. The controlled slow down method is preferably initiated when the engine speed exceeds an activation speed for a predetermined number of engine revolutions. Once initiated, the controlled slow down method uses a combination of ignition timing and spark ratio manipulations in order to disrupt the auto-ignition conditions and slow down the engine in a controlled manner. Preferably, the controlled slow down method is only one part of an overall ignition control method, and can be incorporated within or utilized by one of a number of different ignition timing methods known in the art.
摘要:
A method and system for operating an engine wherein ignition of the engine is activated according to a predetermined timing schedule that references engine speed, and the ignition is suppressed above a predetermined engine speed threshold to allow engine speed to fall below the predetermined engine speed threshold. Thereafter, ignition is reactivated according to timing that is retarded relative to the predetermined timing schedule for a predetermined number of engine revolutions substantially when the engine speed has fallen below the predetermined engine speed threshold, thereby mitigating undesirable spikes in combustion chamber maximum pressure.

Synthetic nano-sized crystalline calcium phosphate, particularly hydroxyapatite, having a specific surface area in the range of 150 m2/g to 300 m2/g, is described. The nano-sized crystalline calcium phosphate may be in the form of a powder or in the form of a coating on a surface. A method of producing a nano-sized crystalline calcium phosphate powder or coating is also described.

摘要:
Synthetic nano-sized crystalline calcium phosphate, particularly hydroxyapatite, having a specific surface area in the range of 150 m2/g to 300 m2/g, is described. The nano-sized crystalline calcium phosphate may be in the form of a powder or in the form of a coating on a surface. A method of producing a nano-sized crystalline calcium phosphate powder or coating is also described. The method comprises formation of a liquid crystalline phase in a water solution of calcium, phosphor and a surfactant, placing the phase in an ammonia atmosphere so that nano-sized crystals are formed, followed by either removal of the surfactant with a solvent and recovering the nano-sized crystals to obtain the powder, or diluting the ammonia-treated liquid crystalline phase with a hydrophobic organic solvent to create a microemulsion of the nano-sized crystals in water, dipping an oxide layer-coated surface of an object into the microemulsion, or alternatively saving the step of ammonia treatment of the liquid crystalline phase until after the dipping of the surface of an object into the microemulsion, followed by removal of the organic solvent and the surfactant from the surface to obtain the coating.
