摘要:
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.

The fracturing methods can provide an advantage over the current fracturing methods. The disclosed fracturing methods can change the fracture gradient of the downhole subterranean formation. For example, one or more of the fracture gradients of the low and high stress zones of the downhole subterranean formation can be changed. Furthermore, the methods of present disclosure, in relation to current practices, can decrease the extent and/or degree of fracturing within low stress downhole formations and increase the degree of fracturing within high stress formations.

Included are embodiments for identifying the appropriate healthcare provider in which to assign outcome data from an inpatient case. Some embodiments include compiling inpatient cases for a healthcare facility, determining an attributable case by matching attribution indicator data for each of the inpatient cases with case data for each of the inpatient cases, and scoring physician activities based on the attribution indicator data. Some embodiments include attributing the inpatient cases to a physician, based on the scoring and providing the attribution to a user.

The present invention provides a method for preparing silica containing molecular sieves which may be mixed with an organic polymer to create a mixed matrix membrane. Further, this invention includes a method of making such a mixed matrix membrane and the membrane itself. A process for separating component gases from a mixture using the subject mixed matrix membrane is also described. The method for preparing silica containing molecular sieves comprises super water washing silica containing molecular sieves to produce water washed molecular sieves which are substantially free of surface remnants. Super water washing also ideally lowers the concentration of alkali metals in the molecular sieves. The water washed sieves are sufficiently free of surface remnants such that when the water washed sieves are subjected to a Sieve Wash Conductivity Test, a wash filtrate is produced having a conductivity of less than 110 micro mhos/cm, more preferably less than 80 micro mhos/cm, even more preferably less than 50 micro mhos/cm, and most preferably less than 30 micro mhos/cm. It is believed that super washing the sieves to this degree will enhance, compared to conventional preparation techniques, the ability of the molecular sieves to bond with an organic polymer to form a highly selective and permeable mixed matrix membrane.

Some application modules of a sidebar comprise a list of items. For example, an email module comprises message items while a photo slideshow does not comprise items. In known sidebars, the number of items in an application module display area is not discrete. For example, in an email module the last item in the list can be partially displayed. In one embodiment, application modules that comprise items are forced to display a whole number of menu items. When a user resizes an application module, the application module will “snap” to fully include or fully exclude an item as opposed to displaying a partial item. A whole item display format can also be implemented in an application module's slidesheet.

The invention concerns a vehicle body panel. The vehicle body panel, such as a floor pan, may have a generally planar portion adapted to be located adjacent to and conceal a vehicle component, such as a fuel pump module. An access portion is located within and extends out of plane of the generally planar portion, and includes a periphery, wherein the access portion is integral with the generally planar portion. Also, a cutting guide feature extends around it adjacent to the periphery.

This invention relates to crystals comprising apo-LsrB and holo-LsrB. The structure of holo-LsrB identifies a tetrahydroxytetrahydrofuran derived from 4,5-dihydroxy-2,3-pentanedione (DPD) as the active autoinducer-2 (AI-2) molecule in Salmonella typhimurium. The X-ray crystallographic data can be used in a drug discovery method. Additionally the invention provides AI-2 analogs based on this discovery as well as pharmaceutical compositions containing those analogs.

A game or other software program is made accessible for execution by clients on a peer-peer network only after a plurality of verifications are made to ensure that control of the software is maintained. With a request sent to a server to access the software, a client includes a nonce and an ID of the user. The server digitally signs a portion of a ticket that is returned to the client, which includes the nonce, a time stamp, and the ID. The ticket is required to access the software. The clients are required to exchange the tickets, verify the digital signature on the portion of each ticket, and use the information therein to confirm that the tickets are current, issued by the correct server, issued to the proper users, and received from the users who are intended to execute the software.

A process for the hydroisomerization of a waxy feed having a major portion boiling above 650° F. to produce a lubricating base oil having a lower pour point, said process comprising (a) passing the waxy feed along with hydrogen gas through a hydroisomerization zone maintained at a hydrogen partial pressure of between about 100 psia and about 400 psia, said hydroisomerization zone comprising a catalyst bed containing at least two active wax hydroisomerization catalysts, said catalysts comprising at least (i) a first catalyst comprising an active hydrogenation component and a 1-D, 10-ring molecular sieve having a maximum crystallographic free diameter of the channels equal to 6.2 Å units or greater and (ii) a second catalyst comprising an active hydrogenation component and a 1-D, 10-ring molecular sieve having a maximum crystallographic free diameter of the channels equal to 5.8 Å units or less, wherein the weight ratio of molecular sieve contained in the first catalyst to the molecular sieve contained in second catalyst in the hydroisomerization zone falls within the range between about 2 to 1 and about 12 to 1; and (b) recovering from the hydroisomerization zone a lubricating base oil having a lower pour point as compared to the waxy feed.
摘要:
A method and apparatus for creating firestopping barrier in a partition, such as a wall, floor, or ceiling, that is mounted adjacent the opening includes a housing containing a central opening. The cross-sectional area of the housing is greater than the cross-sectional area of the through-penetration opening, and the housing is arranged external to the through-penetration opening with at least a portion thereof extending along a surface of the partition thereby to allow the housing to be installed adjacent the through-penetration opening. Firestop material is arranged within the housing.
