An improved axial flow chromatography column for separations dependent upon bed depth, such as size exclusion and where changes of column volume necessitate bed height adjustments. The improvements include a snap-action lever or a collet arrangement which permits quick and easy movement of the bed adjuster; a flush seal assembly at the outlet frit and a V-shaped seal in the bed adjuster which obviates dead volume gap of conventional O-ring seals; lens-shaped frits convex on the inlet and outlet sides provide for uniform flow through the column, and the access ports eliminate the contamination problem by providing easy access for cleaning and aspiration of liquid; and a combined inlet tube and adjuster tube assembly eliminates the need for threaded components which make sanitation difficult.

The present invention contemplates a risk management system for facilitating an e-commerce transaction wherein the participants to the transaction engage in commerce using different currencies. An automated sales risk management system facilitates a transaction by providing a price of a transaction which incorporates aggregated costs related to the transaction into a price made available to the participants. A currency risk management system can receive an amount relating to a deliverable involved in a transaction and determines an aggregated cost of the transaction. Aggregated cost can include a cost of credit, a cost for exchange of currency, a cost of insurance, processing fees, or other associated costs. Insurance can be monitored and a determination can be made regarding whether a participant has adequate insurance to cover a proposed transaction. The present invention also provides for risk associated with online transactions to be categorized and transferred.

A method for marine seismic surveying includes towing a seismic sensors in a plurality of streamers in the water, actuating a seismic energy source in the water at selected times and detecting seismic signals at the sensors resulting from the actuation of the source. A data trace is created for each of the detected signals. At least one Fresnel zone is determined for at least some of the seismic data traces. A contribution of each of the traces to each one of a plurality of bins defined in a predetermined pattern is computed, based on the Fresnel zone associated with each trace. Based on the computed contributions, a maximum lateral distance between corresponding seismic sensors is determined that will result in a contribution sum above a selected threshold.

Provided herein are methods for the combined amplification and detection of one or a plurality of target nucleic acid molecules. The methods encompass the use of an antisense strand of a catalytic nucleic acid in a primer for amplification such that an amplicon produced thereby includes an active catalytic nucleic acid capable of indicating the presence of the target sequences through the modification of a reporter substrate. Devices and kits are also provided. DNA molecules for practicing the methods are also provided. The DNA molecules comprise at least a first portion complementary to at least a first portion of a target nucleic acid sequence, a second portion complementary to an antisense sequence of a second portion of the target nucleic acid sequence, and a third portion comprising an antisense sequence of a catalytic nucleic acid; the third portion positioned between the first and second portions of said DNA molecule.

The present invention related to three novel recognition protein expressed by keratinocytes, wound-healing tissues and chondrosarcoma tissue. More specifically, isolated nucleic acid molecules are provided encoding human peptidoglycan recognition protein-related proteins, referred to herein as PGRP-K (Keratinocytes), PGRP-W (Wound-healing), and PGRP-C (Chondrosarcoma) of FIGS. 1A-B, FIGS. 2A-C, and FIG. 3, respectively, each having homology to both human peptidoglycan recognition protein (PGRP) as well as murine Tag-7. PGRP-K, PGRP-W, and PGRP-C polypeptides are also provided. Further provided are vectors, host cells and recombinant methods for producing the same. The invention also relates to both the inhibition and enhancement of activities of PGRP-K, PGRP-W, and PGRP-C polypeptides and diagnostic methods for detecting PGRP-K, PGRP-W, and PGRP-C gene expression.

摘要:
The present invention provides a method and system to implement risk management of foreign exchange of currency related to an online transaction. According to the present invention an exchange price and a tolerance parameter can be determined for a foreign currency as the foreign currency relates to a base currency. A computer system can receive a spot price relating to a market price for exchange of a foreign currency and compare the spot price with the tolerance parameter. The system can modify the exchange price if spot price exceeds the tolerance parameter. In addition, the system can receive information including the base currency amount involved in an online transaction and transmit the base currency amount and the foreign currency amount, wherein the foreign currency amount is derived according to the exchange price. If desired, a first tolerance parameter and a second tolerance parameter can be utilized, wherein a rise in the spot price is compared to the first tolerance parameter and a fall in the spot price is compared to the second tolerance parameter. In addition, the magnitude of the first tolerance parameter does not need to be equal to the magnitude of the second tolerance parameter. A rise in the spot price can be compared to the tolerance parameter such that the exchange price is modified if the spot price is higher than the tolerance parameter. Similarly, only a fall of the spot price can be compared to the tolerance parameter such that the exchange price is modified if the spot price is lower than the tolerance parameter. Additionally, a spot price can be determined and compared to the tolerance level at predetermined periods of time. An original tolerance level can be modified to create a new tolerance level, if the spot price exceeds the original tolerance level.
