摘要:
The invention provides a method for the purification of cytochrome P450 molecules, the method comprising expressing in a host cell culture a cytochrome P450 molecule; recovering said cells from said culture and suspending said cells in a high salt buffer; lysing said cells and removing cell debris to provide a high-salt lysate; adding to said lysate a detergent to provide a high-salt-detergent lysate; and recovering said P450 from said lysate. The method provides yields of P450 proteins suitable for crystallization.

A body for a blow-molded waste cart and a waste cart having a blow-molded hollow body with four upstanding side walls and corner sections therebetween, a floor, and a circumferential compression flange around the side walls and corner sections is disclosed. The waste cart may also include an axle and wheels mounted to a side wall and a handle assembly with lid also mounted to a side wall. The circumferential compression flange may have a generally consistent width and thickness at each of the side walls and corner sections and the lid rim meets the circumferential compression flange when the lid is closed. A method of forming a blow-molded waste cart body is also disclosed. The process includes melting a polymer material to form a parison, enclosing the parison in a main mold, pressurizing the parison within the mold and moving a secondary mold section onto the main mold squeezing the polymer outward to a gap between the secondary mold and main mold to form the circumferential flange.

A body for a blow molded waste cart and a waste cart having a blow-molded hollow body having a front wall and a central channel formed in the front wall, a lift pocket formed in the central channel, and a lift pocket reinforcement insert molded into the lift pocket. The lift pocket reinforcement has a main body formed with a longitudinal axis, an upper face, a rear face including a generally planar lift contact surface and a plurality of retention keys that retain the polymer of the parison after molding. The retention keys may be undercut to improve retention of the polymer. The lift pocket reinforcement may be blow-molded and the retention keys may be in the shape of a section of a trapezoidal cone.

A dilatation balloon and catheter for insertion into a bodily conduit. The catheter (10) includes shaft (12) and a dilatation balloon (24) at the distal end of the shaft. The balloon is inflated via a central lumen (14) in the shaft for delivery of a fluid inflation media. The balloon is fabricated from a combination of a thermoplastic elastomer (TPE), preferably an engineering thermoplastic elastomer (ETE), with a non-compliant structural polymeric material. The combination may be a blend of the non-compliant structural polymer and the TPE. Alternatively, the combination may be a layered balloon having, for example, a non-compliant structural polymer inner layer and a soft, abrasion resistant, elastomeric outer layer. Methods for fabricating the balloon from the combination of a TPE and a non-compliant structural polymer are also disclosed.
摘要:
A distributed system that uses distributed synchronized time to perform uncorrelated actions. A distributed system according to the present teachings includes a set of nodes each having a synchronized real-time clock. The nodes use the synchronized real-time clocks to trigger a set of uncorrelated actions from the nodes.

Decimation of data from a fixed length queue retaining a representative sample of the old data. Exponential decimation removes every nth sample. Dithered exponential decimation offsets the exponential decimation approach by a probabilistic amount. Recursive decimation selects a portion of the queue and removes elements.

One embodiment of the present invention separates the region of measurement space into a plurality of sub-regions and calculates a confidence, for reconstruction of an underlying signal within said space, corresponding to each of the sub-regions. This embodiment can then accept measurements from mobile measuring devices within said measurement space and store those measurements if they originate from devices in sub-regions having a confidence below an acceptable value.

摘要:
By using advanced data communications transport methodology, remote electronic vaulting systems and methods provide a networked-based solution to facilitate the transportation of production data between the production data processing center and an off-site storage location. A local access network is used to facilitate data transport from the production data processing facility to the closest long-haul distance network point of presence facility. The point of presence facility houses an electronic storage device which provides the off-site storage capability. A user can then manipulate transportation to data from the production data processing center to the data storage facility using channel extension technology to store the data in electronic form on standard disk or tape storage devices. The user can then recall, copy or transmit the data anywhere on demand under user control by manipulating switching at the point of presence. This subsequent electronic data transfer can be designed to move the critical data on demand at time of disaster to any disaster recovery facility.
