摘要:
The invention described herein relates to the detection, diagnosis, and treatment of intestinal metaplasias that develop to esophageal, gastric, and pancreatic adenocarcinoma. The stem cells and differentiated cells of these intestinal metaplasias show high expression of CDH17 as well as other proteins. The invention also includes a clonal population of Barrett's esophagus stem cells as well as the stem cells of the surrounding normal epithelia and methods of using them for the detection, diagnosis, and treatment of Barrett's esophagus.

Disclosed herein is a system for allowing a remote user to purchase, over a distributed computer network (e.g., the Internet), an option for a ticket and/or accommodations for a ‘contingent event”, e.g., an event which is certain to occur but for which the participants, content and/or location(s) are not predetermined. For instance, the subject system can be used to sell options for the purchase of tickets to such contingent events such as playoff games on the basis of what teams qualify, or all-star game.

摘要:
In a process for converting methane to higher hydrocarbons including aromatic hydrocarbons, a feed containing methane is contacted with a dehydrocyclization catalyst under conditions effective to convert said methane to aromatic hydrocarbons and produce a first effluent stream comprising aromatic hydrocarbons and hydrogen, wherein said first effluent stream comprises at least 5 wt % more aromatic hydrocarbons than said feed. At least part of the hydrogen from said first effluent stream is then reacted with an oxygen-containing species, such as carbon dioxide, to produce a second effluent stream having a reduced hydrogen content compared with said first effluent stream.

The invention provides a steering column assembly (10) having a first steering column member (12) with an upper end (14) and a mounting feature (16). The mounting feature (16) is operative to support against rotation relative to a vehicle and includes first and second mounting portions (30, 32). The steering column assembly (10) also includes a second steering column member (18) having a lower end (20). The second steering column member (18) is operatively connected to the first steering column member (12) for telescoping movement along a column axis (22). The steering column assembly (10) also includes a first bushing (24) connected to the upper end (14) and disposed between the first steering column member (12) and the second steering column member (18) for supporting the telescoping movement. The steering column assembly (10) also includes a second bushing (26) connected to the lower end (20) and disposed between the first steering column member (12) and the second steering column member (18) for supporting the telescoping movement. The second bushing (26) is disposed between the first and second mounting portions (30, 32) along the column axis (22).
摘要:
There is provided a catalyst composition having improved hydrothermal stability for the catalytic cracking of a hydrocarbon feedstock to selectively produce propylene. The catalyst composition comprises a first crystalline molecular sieve selected from the group consisting of IM-5, MWW, ITH, FER, MFS, AEL, and AFO and an effective amount of a stabilization metal (copper, zirconium, or mixtures thereof) exchanged into the molecular sieve. The catalyst finds application in the cracking of naphtha and heavy hydrocarbon feedstocks. When used in the catalytic cracking of heavier hydrocarbon feedstocks, the catalyst composition preferably comprises a second molecular sieve having a pore size that is greater than the pore size of the first molecular sieve. The process is carried out by contacting a feedstock containing hydrocarbons having at least 4 carbon atoms is contacted, under catalytic cracking conditions, with the catalyst composition.

A database system is disclosed. The database system includes a common data repository, a document indexing database and a query engine. The common data repository is configured to store data in a common data table and is associated with a data object. The document indexing database is configured to store a data structure model that is associated with a unique document type. The data structure model is configured to facilitate retrieval of data stored in the common data table. The query engine is communicatively linked to the document indexing database and the common data repository. The query engine is configured to use the data structure model to retrieve data from the common data table.
