A method of eluting metal ions from a bed of metal-loaded chelating resin wherein the resin includes a crosslinked styrene-divinylbenzene copolymer matrix with pendent methyleneaminopyridine or phosphonic acid groups and the method includes the step of passing an eluant through the bed to at least partially remove the metal ions from the chelating resin and create a metal-rich eluate, wherein the eluant includes an aqueous solution comprising an amino acid compound having a molecular weight less than 500 Daltons.

The present invention provides methods and systems of conducting wagers, such as pari-mutuel wagers. In one exemplary embodiment, an event, such as a horse race, dog race, a combination of races, etc., is identified for which a plurality of bettors may each place at least one wager. Each bettor of the plurality is enabled to provide input regarding at least one portion of their respective at least one wager prior to the event. At least one other portion of each bettor's at least one wager is randomized prior to the event. The wager then comprises the combination of the bettor selected portion and randomized portion. In one exemplary embodiment, the player selected portion may include selecting bettor-preferred participants of the event while the randomly selected portion may include the randomly assigning a finishing order to the player selected participants.

Methods and systems of pari-mutuel wagering are disclosed to facilitate the wager construction process. In one method, patrons select runners, and betting options of selected runners are presented. In another method, a first wager is placed and other wagers are presented, wherein the additional wagers may include a runner of the first wager. Another method allows patrons to wager on a runner, wherein an area representing the runner is marked to indicate that this runner was selected on a previous wager or in the current wager. In another method, a portion of a wager is patron selected and a portion of the wager is suggested by the betting interface. In another method, patrons may construct wager(s) for single or future races, or specify criteria for those wagers. In another method, runners are displayed in a table and patrons may select or deselect runner combinations by selecting cells within the table. Methods and systems of pari-mutuel wagering that enable an organization to set rules to display the gaming activity, and an embodiment where players make subscription as well as programmed bets are described.

A load transport device that mounts to a vehicle mounted trailer hitch. The load transport system comprises a channel portion fitted with a pinion gear, and the channel portion is rigidly attached to a mounting bar that slideably engages a receiver portion of a vehicle's trailer hitch. The device also comprises an invertible shaft with an optionally-motorized rack gear system. The invertible shaft has a channel portion insertion end and a load lifting end. The invertible shaft slideably engages in either a load-low or load-high orientation depending on which end, the insertion end or the load lifting end first engages with the channel portion. The pinion gear and the rack gear system are functionally engaged. The load transport device further comprises a load support member attached to the load lifting end and comprising one or more bars that support a load.

A fluid delivery module for use in preparing a substrate is provided. The fluid delivery module includes a process bowl designed to contain a substrate to be prepared. The process bowl has a bottom wall and a sidewall. The fluid delivery module further includes a fluid delivery ring configured to be attached to the sidewall of the process bowl. The fluid delivery ring includes a plurality of inlet and outlet pairs. Each of the plurality of inlet and outlet pairs is defined in the fluid ring and is designed to receive a respective supply tube. Each respective supply tube has an end that terminates at each of the outlets of the fluid delivery ring and is configured to direct fluid onto a surface of the substrate.
摘要:
A live attenuated human immunodeficiency virus type 1 (HIV-1) whose replication is not constitutive but is instead conditionally regulated (such that rounds of reverse transcription with accompanying potential for error are strictly limited) might yield a paradigm that minimizes evolution to virulence and facilitate vaccine development. We have broached the concept of conditional control of HIV-1 through gain-of-function. Here, we describe the design of constitutively inactive HIV-1 genomes (HIV-DoxT and HIV-DoxSp) which can be conditionally resuscitated to an active state by tetracycline or related analogues. The HIV-DoxT construct comprises an inactivating mutation engineered into TAR, thereby rendering the virus non-responsive to Tat, a 302-bp DNA fragment (TetopT) which contains the tet-operator ligated into a position upstream of the HIV TATAA box, in both the 5′ and 3′ LTRs, and a reverse tetracycline-controlled activator (RTTA) coding sequence in place of the nef coding region. The HIV-DoxSp construct contains three additional Sp1 sites in the TetopT promoter upstream of the TATAA box thereby generating the promoter TetopSp. Genotypically, HIVDoxT is tat(+)tar(−)nef(−)Sp1(−) and HIVDoxSp is tat(+)tar(−)nef(−)Sp1(+). Since both genomes are genetically tar(−), they would ordinarily be expected to be wholly defective in producing viral proteins and/or particles. However, following transfection into an appropriate cell target, both proviruses, in a doxycycline-dependent fashion, capably released Gag and RT from cells. In the absence of doxycycline, no replication competent virus could be recovered. These findings suggest that the heterologous RTTA+Dox mechanism substituted effectively for Tat/TAR. These constructs should prove useful in the development of HIV-specific immunological and diagnostic reagents.

Synthetic composite materials for use, for example, as orthopedic implants are described herein. In one example, a composite material for use as a scaffold includes a thermoplastic polymer forming a porous matrix that has continuous porosity and a plurality of pores. The porosity and the size of the pores are selectively formed during synthesis of the composite material. The example composite material also includes a plurality of a anisometric calcium phosphate particles integrally formed, embedded in, or exposed on a surface of the porous matrix. The calcium phosphate particles provide one or more of reinforcement, bioactivity, or bioresorption.
