摘要:
Molecular sieves are prepared by forming a reaction mixture slurry, spray drying the reaction mixture slurry to form particles, and heating the spray dried reaction mixture at a temperature and pressure sufficient to cause crystallization of the molecular sieve. The reaction mixture contains an organic templating agent capable of forming the molecular sieve. The template may be added to the reaction mixture either by adding all of the template prior to spray drying, or by adding a portion of the template prior to spray drying with the remainder being added after spray drying.

An integrated process for preparing a lubricating oil base stock includes an isomerization step followed by a solvent dewaxing step. A waxy feed is isomerized to an intermediate pore point, which is at least 6° C. above a target pour point, over a select molecular sieve having specified pore properties. The isomerized oil is then solvent dewaxed to a very low pour point. This process produces a dewaxed lubricating oil base stock which has an exceptionally high viscosity index.

A downhole preferential hydrocarbon gas recovery system and method employ preferentially selective materials to separate the hydrocarbon gas from contaminants. According to one aspect of the invention, the preferentially selective materials are arranged in tubes with the hydrocarbon gas flowing through the tubes and the contaminants permeating out through the preferentially selective material.
摘要:
A peptide comprising a free terminal alpha amine is treated with an aryl sulfonamide activating agent, resulting in an activated amide. The resulting activated amide is deprotonated with a base and modified by the addition of a substituent group. The aryl sulfonamide activating group is cleaved using a nucleophilic substitution reaction. The method is particularly useful for the modification of peptides at specific N-alpha positions, and is compatible with conventional solid phase peptide synthesis, including those that utilize Fmoc protecting groups.
摘要:
A new method, system and apparatus for mounting mechanically, thermally and electrically light emitting diode (LED), crystals, arrays or packages. The above provides an LED assembly having reduced number of components and costs, superior heat dissipation, mechanical properties and a compact structure. The use of a grid or mesh allows for more efficient and inexpensive removal of heat from one or more LEDs within an LED fixture.

Disclosed herein is a method of making a crosslinked membrane such as a crosslinked hollow fiber membrane. The method comprises (a) preparing a polyimide polymer comprising carboxylic acid functional groups from a reaction solution comprising monomers and at least one solvent; (b) treating the polyimide polymer with a diol at esterification conditions to form a monoesterified polyimide polymer; (c) forming a monoesterified polyimide membrane or dense film from the monoesterified polyimide polymer; and (d) subjecting the monoesterified polyimide membrane or dense film to transesterification conditions under a CO2 atmosphere to form a crosslinked polyimide membrane or dense film.
摘要:
Apparatus and methods implementing a hardware queue management device for reducing inter-core data transfer overhead by offloading request management and data coherency tasks from the CPU cores. The apparatus include multi-core processors, a shared L3 or last-level cache (“LLC”), and a hardware queue management device to receive, store, and process inter-core data transfer requests. The hardware queue management device further comprises a resource management system to control the rate in which the cores may submit requests to reduce core stalls and dropped requests. Additionally, software instructions are introduced to optimize communication between the cores and the queue management device.

The present invention utilizes carrier particles to present antigen peptides and proteins to the immune system in such a way as to induce antigen specific tolerance. The carrier particle is designed in order to trigger an immune tolerance effect. The invention is useful for treatment of immune related disorders such as autoimmune disease, transplant rejection and allergic reactions.
摘要:
The present invention relates to a method of using an image warping software algorithm to perform a real time alteration of a display scene running under the MICROSOFT WINDOWS OPERATING SYSTEM to mitigate the inherent distortion of a Stark lens cover. The image warping software algorithm alters the display scene and allows an observer to view the display scene as a single unbroken image when the display scene is distributed across multiple display screens. The purpose of the image warping software algorithm is to significantly reduce the distortion observed at the abutting edges of the joined display screens.
