Abstract: A method and apparatus for measuring a misting property of fluids, the method and apparatus simulating mist generation of fluids in machining processes. Fluid is supplied to mist generating means in an enclosure and energy input to the fluid by the mist generating means is controlled. Mist laden gas flows from the vicinity of mist generation to a mist concentration measuring means. Droplets of relatively large mass are removed from the mist prior to the flow of gas reaching the mist concentration measuring means. To further simulate machining processes, the fluid of interest is recirculated from a reservoir through the mist generating means. Mist concentration measurements produced under the same conditions for fluids of different compositions are compared to characterize the misting properties of fluids.

Abstract: The stackable plastic cover allows a series of covers to be stacked into a column. This is achieved by increasing the sidewall taper to allow the inside of one cover to nest down over the outside of the adjacent cover. Conical projections on the outside of the tapered wall surface provide a stop for the adjacent cover to rest upon and additional conical projections are placed above the stops to prevent scratching of the covers and wall sections.

Abstract: A method for prefetching structured data, and more particularly a mechanism for observing address references made by a processor, and learning from those references the patterns of accesses made to structured data. Structured data means aggregates of related data such as arrays, records, and data containing links and pointers. When subsequent accesses are made to data structured in the same way, the mechanism generates in advance the sequence of addresses that will be needed for the new accesses. This sequence is utilized by the memory to obtain the data somewhat earlier than the instructions would normally request it, and thereby eliminate idle time due to memory latency while awaiting the arrival of the data.

Abstract: Detection of fetal nucleated red blood cells (NR-BCs) is achieved by employing a combination of bright-field and fluorescence images of nuclear and cytoplas-mic markers. The brightfield and fluorescence images are all obtained with a single multi-bandpass dichroic mirror. The objects in the sample are stained with a fluorescent dye that selectively stains nuclei and a dye that selectively stains fetal hemoglubin in the cytoplasm of fetal RBCs. UV excitation provides fluorescent emissions from the stained cell nuclei and visible illumi-nation provides brightfield transmission of light that is absorbed by the stained cytoplasm. The images are processed to determine regions where the fluorescent emissions by cell nuclei in response to the UV  exci-tation and the absorption by fetal hemoglobin of the brightfield illumination overlap or are in close proximity. The brightfield and fluorescence images may be sequentially acquired or derived from a single image where the UV excitation and visible illumination occur simultaneously.

Abstract: Biocompatible polyhydroxyalkanoate compositions, particularly based on biotechnologically produced homo- and copolymers of 4- hydroxybutyric acid, with controlled degradation rates have been developed.  In one embodiment, the polyhydroxyalkanoates contain additives like, for example, pore forming agents to alter the degradation rates. In another embodiment, the polyhydroxyalkanoates are formed of mixtures of monomers or include pendant groups or modifications in their backbones to alter their degradation rates. In still another embodiment, the polyhydroxyalkanoates are chemically modified. Methods for manufacturing the devices which increase porosity or exposed surface area can be used to alter degradability. As demonstrated by the examples, these polyhydroxyalkanoate compositions have extremely favorable mechanical properties, as well as are biocompatible and degrade within desirable time frames under physioogical conditions. These polyhydroxyalkanoate materials provide a wider range of polyhydroxyalkanoate degradation rates than are currently available. Methods for processing these materials, particularly for therapeutic, prophylactic or diagnostic applications, or into devices which can be implanted or injected, are also described.

Abstract: This invention relates to a shock absorbing docking spacer to space a tethered boat from dockside. It comprises an elongated body having two cylindrical sections moveable longitudinally of each other to define spacer length with one of said cylindrical sections being connectable to a boat and the other of said cylindrical sections being connectable to a dock. A resilient cord is connected at one of its ends to one of said cylindrical sections and at the other of its ends to the other of said cylindrical sections to be tensioned as the cylindrical sections move longitudinally of each other due to shock forces in use to reduce spacer length. The cord has a resilience as aforesaid to absorb shock forces on the boat that reduce the spacer length in use, and to reassert itself and restore spacer length when shock forces are removed.

Abstract: An optical network unit of each consumer is connected to an optical line terminator of a network operator through a subscriber line formed of an optical fiber. When a particular consumer desires to download digital content from a content retailer to the particular consumer through a network of the network operator, the particular consumer requests a bandwidth reservation of a resource reservation server of the network operator, so that a transmission condition composed of a bandwidth and a time zone is reserved in cases where the downloading of the digital content at the transmission condition is possible. Thereafter, the bandwidth reservation is sent to a downward bandwidth managing unit, and the digital content is downloaded from the content retailer to the particular consumer through the network of the network operator at the transmission condition according to the bandwidth reservation under control of the downward bandwidth managing unit. Accordingly, a time period required for the downloading of the digital content can be easily predicted, and an operational efficiency of the downloading can be improved.

Title: Intein mediated peptide ligation
Inventor: XU MING-QUN
IPC: C12P21/02
Filed: 1999-09-30
Granted: 2011-11-29
Abstract: An in vitro method for producing a semi-synthetic fusion protein is provided, whereby a target protein fused to an intein - a protein splicing element - is selectively cleaved in a first step as depicted in Figure 1 with a thiol reagent, forming a carboxyl-terminal thioester of the target protein and releasing the target protein from the intein. In a subsequent step as shown in Figure 1, a desired, synthetic, protein or peptide having an amino-terminal cysteine is ligated to the target protein. Standard thiol-reagents such as DTT, or thiol-reagents optimized for ligation such as the odorless MESNA, may be used in the first step. The method permits the direct ligation of a desired peptide to a thioester bond that had linked a target protein to an intein. An in vivo variation of the method will permit production of a cytotoxic protein: a truncated, inactive, form of the protein fused to an intein is introduced in vivo, this fusion product is then selectively cleaved, and a synthetic protein or peptide is subsequently ligated at a carboxyl-terminal thioester of the target protein in order to restore the native activity of the cytotoxic protein.
