摘要:
The present invention is a method to determine the TAN and TAN as a function of boiling point for a hydrocarbon feedstream using an electrospray ionization mass spectrometer (ESI-MS). The steps of the method include determining the signal as a function of mass from the ESI-MS while minimizing the formation of oligomers and fragmentation of the molecular species in the feedstream and then determining the TAN from the signals. The TAN is also determined as a function of boiling point.
摘要:
The present invention is a method to determine the composition of a hydrocarbon feedstream from a small sample of hydrocarbons including the steps analyzing the sample with a combination of chromatograph and mass spectrometer, and reconciling output from step a) with other analytical measurements to determine to determine the composition of the hydrocarbon feedstream.
摘要:
A distribution system and method. The distribution system comprises a computing apparatus and a plurality of projection systems connected to the computing apparatus. The computing apparatus comprises a scheduler software tool and a plurality of audio/video data files stored on a computer readable medium. Each projection system of the plurality of projection systems comprises a cache storage device connected to an associated projection apparatus. Each cache storage device is adapted to dynamically receive and store an associated audio/video data file from the plurality of audio/video data files for transmission to each associated projection apparatus according to a schedule generated by the scheduler software tool.
摘要:
A method and system for managing an electronic commerce (e-commerce) shopping cart relating to communication between a shopper and a server over a communication network. A server whether a shopping command of the shopper has changed an attribute of a primary item in the shopping cart. After the server has determined that the shopping command has changed the attribute of the primary item in the shopping cart, the server identifies a secondary item in the shopping cart linked to the primary item. The server changes a corresponding attribute of the secondary item in response to the change in the attribute of the primary item, wherein the attribute of the primary item is a quantity of the primary item, a color of the primary item, or a size of the primary item.
摘要:
An electrochemical cell with an alkali metal containing anode having high discharge capacity, charge efficiency and low self-discharge. The addition of at least one nitramide or dinitramide salt of a metal cation to the electrochemical cell electrolyte unexpectedly lowers first cycle irreversible capacity, adds higher cycle life, lowers self-discharge and beneficially addresses several additional degrees of freedom with respect to electrolyte solvent selection while providing higher charge capacity. Additives include the lithium metal salts of nitramide or dinitramide, and the electrolyte consists essentially of a lithium metal salt dissolved in a at least one of an aqueous solvent, molten salt solvent system and a non-aqueous solvent mixture of at least one of organic ethers, esters, carbonates, acetals.

A server identifies a secondary item in the shopping cart linked to a primary item in the shopping cart. The server changes an attribute of the secondary item in response to a change in a corresponding attribute of the primary item. The server removes the secondary item from the shopping in response to removal of the primary item from the shopping cart.
