Methods and devices are provided for treating multiple interval well bores. More particularly, an isolation assembly may be used to allow for zonal isolation to allow treatment of selected productive or previously producing intervals in multiple interval well bores. One example of a method for treating a multiple interval well bore includes the steps of: providing an isolation assembly comprising a liner and a plurality of swellable packers wherein the plurality of swellable packers are disposed around the liner at selected spacings; introducing the isolation assembly into the well bore; allowing at least one of the plurality of swellable packers to swell so as to provide zonal isolation of at least one of a plurality of selected intervals; establishing fluidic connectivity to the at least one of a plurality of selected intervals; and treating the at least one of a plurality of selected intervals.

A method for treating a food processing facility by inoculating a food processing facility with an amount of non-spoilage and non-pathogenic bacteria to competitively inhibit the growth of pathogenic and spoilage bacteria, and in particular, a facility that processes food such as dairy products, fruit, vegetables, grains and meat from poultry, beef, pork, lamb, fish and seafood.
摘要:
The present invention relates to methods for the stereospecific synthesis and for the enantiomeric enrichment of β-amino acids. A novel D-β-aminotransferase, which exhibits stereoselectivity for D-β-phenylalanine, (D-3 amino-3-phenylpropinine acid) was purified from a newly-isolated strain of Variouorax paradoxus. A novel L-β-aminotransferase was purified from a newly-isolated strain of Alcaligenes eutrophus. The D- and L-β-aminotransferases can be used to facilitate the stereoselective biosynthesis of β-D-phenylalanine or β-L-phenylalanine, from a mixture of L-glutamic acid or L-alanine, respectively, and 3-keto-3-phenylpropionic acid in the presence of the cofactor pyridoxal phosphate.

A surfboard baffle arrangement system may be provided utilizing a watercraft body having a first side surface and a second side surface. The surfboard baffle arrangement system may further utilize an array of baffle structures disposed into the watercraft body and through the first side surface. Each baffle structure within the array of baffle structures may have a baffle retainer and a baffle panel such that the baffle panel and the baffle retainer may be operably coupled to one another. Further, the baffle panel may have one degree of freedom of rotation relative the baffle retainer such that the one degree of freedom of rotation utilizes rotation of the baffle panel between an open configuration and a closed configuration.

There are disclosed agents that inhibit Blood Brain Barrier Proteins (BBBP). Such agents are useful in controlling agents entering and exiting the CNS. This allows for drugs to be more effective and/or allowing side effects of the drugs to be lowered.
摘要:
The system enables a data processing framework that polls for files using a listener, controls the workflow using event driven logic, processes financial transactions, and creates a business to business trading partner network. The listener ensures the reliability and data integrity of input files and performs archiving functions. The payment management functions automatically processes transactions, including payor (e.g., the buyer) initiated payments to a payee (e.g., a supplier) by utilizing a flexible, decoupled processing architecture. A payment management computer identifies a universal identifier for each entity and forms relationships and hierarchies in order to increase efficiency of the trading partner network. Metadata describes the format, validation and relationships for a wide variety of financial account data.
摘要:
An apparatus for imparting mechanical vibration on a down-hole drilling system including a body, first and second couplers and a rotating member. The body includes ports configured to pass fluid through the body, and the first and second couplers are configured to couple the body to the down-hole drilling system. The rotating member is located at least partially in the body and is rotatable about an axis of rotation in response to flow of the fluid such that rotation of the rotating member generates mechanical vibration imparted on the down-hole drilling system.
