As described herein vascular anchoring systems are used to position an implant in a vascular area such as a bifurcated vasculature with relatively high fluid flow, for instance, in an area of a pulmonary artery with associated left and right pulmonary arteries. Implementations include an anchoring trunk member having a first anchoring trunk section and a second anchoring trunk section. Further implementations include a first anchoring branch member extending from the anchoring trunk member. Still further implementations include a second anchoring branch member extending from the anchoring trunk member.

A content delivery network (CDN) service provider extends a content delivery network to gather information on atomically identifiable web clients (called “user agents”) as such computer-implemented entities interact with the CDN across different domains being managed by the CDN service provider. In one embodiment, a set of machines, processes, programs, and data comprise a data system. The data system tracks user agents, preferably via cookies, although one or more passive techniques may be used. A user agent may be a cookie-able device having a cookie store. As the user agent navigates across sites, a CDN-specific unique identifier used by the system to correlate user agents is generated. Preferably, the unique identifier is stored as an encrypted cookie. The unique identifier represents one user agent (and, thus, one cookie-able device's store). The system tracks user agent behavior on and across customer sites that are served by the CDN, and these behaviors are classified into identifiable “segments” that may be used to create a profile. CDN customers use the data system to obtain information that characterizes the user agent.
摘要:
An apparatus for performing a biological or biochemical reaction that, in certain embodiments, has the ability to generate flow in a reaction site container by applying a force to a liquid medium that is outside of the reaction site container. In some embodiments, a flow generating component such as a gas bubble moves within a container and forces an agitating fluid to move through a reaction site container. In some embodiments, the movement of the agitating fluid applies shear stress to cells that are maintained within the reaction site container.

A plasma arc reactor and process for producing a powder from a solid feed material, for example aluminium, is provided. The reactor comprises: (a) a first electrode (5), (b) a second electrode (10) which is adapted to be spaced apart from the first electrode by a distance sufficient to achieve a plasma arc therebetween, (c) means for introducing a plasma gas into the space between the first and second electrodes, (d) means for generating a plasma arc in the space between the first and second electrodes, wherein the first electrode has a channel (7) running therethrough, an outlet of the channel exiting into the space between the first and second electrodes, and wherein means are provided for feeding solid material (20) through the channel to exit therefrom via the outlet into the space between the first and second electrodes.

A sealed attachment fastener assembly with a receiving member and a cap that can be inserted into an opening in a work piece and fixed therein from only one side of the work piece. A portion of the fastener assembly on the blind side of the work piece is collapsible into a flange. In addition, another portion of the fastener assembly is contemporaneously radially expandable within the opening of the work piece to at least rotationally secure the fastener assembly with respect to the work piece. The radial expansion will result in a high interference fit of the fastener in the work piece, which may enhance the fatigue of the installation. A cap completes the fastener assembly to substantially prevent fluid from leaking through the fastener assembly opening. The cap can be assembled with the receiving member after the internal threads within the receiving member have been machined.

Communication devices, such as a radio and a cockpit communication panel, digitally communicate audio signals as digital data without use of a synchronizing clock signal between the devices. The communication panel and the radio function as both a receiver and as a transmitter of digital audio signals. In one embodiment, an analog audio signal is received by the transmitting device and transformed by a coder/decoder (CODEC) into a plurality of signals. The plurality of signals is received and transformed by a field programmable gate array (FPGA) into a digital signal that includes framing pulse and stop bits. The digital signal is transmitted to a FPGA in a receiving device, which transforms the signal into a second plurality of signals. A CODEC in the receiving device transforms the second plurality of signals into an analog audio signal.

Nutritionally improved cultured dairy products such as yogurt products include a fine powdered calcium phosphate salt of reduced particle size having a mean diameter ≦6 μm in amounts sufficient to provide a total calcium content of 0.25% to 0.75%. A method for producing the calcium fortified yogurt is also provided wherein an fine powdered insoluble calcium salt is admixed with a milk blend prior to fermentation. The yogurt is prepared by conventional fermentation. Both stirred style and cup set style yogurt products can be prepared.

The invention generally relates to a fireplace surround for attachment to a fireplace. The surround may include first and second side members formed from a molded material, and a top member formed from the molded material that extends between the first and second side members. The top member defines a cavity that is in fluid communication with a vent of the fireplace to collect heated air from the fireplace. An opening formed in the top member facilitates movement of heated air collected in the cavity to pass through the cavity. The surround may also include a shield member that direct the heated air from the fireplace vent to the exhaust opening in the top member, and an insulating member that dissipates heat in the top member.

This disclosure generally relates to systems and methods for manipulating chambers and other substrates for chemical, biological, or biochemical samples, such as cell culture and other chambers, within units such as incubators. In certain embodiments, the invention provides a technique for maintaining a plurality of substrates or chambers in a housing within which a predetermined environment is maintained, different from the environment external to the housing, and moving substrates or chambers in and out of the housing, in some cases without creating a large opening in the housing (e.g., by opening a door significantly larger than the substrates). A technique is provided, in certain embodiments, in which a plurality of substrates are mounted in fixed, secured relation to each other within a housing providing a predetermined, controlled environment, and are moved within the housing so that they can be evenly exposed to any differences in environment within the housing. In certain embodiments, the invention provides a technique for agitating a fluid within one or more chambers or substrates within a housing that can provide environmental control, in certain embodiments without physically stirring the fluid, such as with a stir bar or other stirring element in direct contact with the fluid. In still another embodiment, the invention provides a method for rotating a substrate or chamber about a substantially vertical and/or horizontal axis. In some cases, any of the above-described systems can be rotated at a speed sufficient to cause separation of a substance within the chamber or substrate.
摘要:
A tubular fastener element is inserted into an opening in a wall until a flange at the trailing end of the fastener element is in contact with the wall. Then, an externally threaded end of a rod is inserted into a center opening in the fastener element from the flange side of the wall and is mated with internal threads in the fastener element beyond the second side of the wall. A tubular mandrel that surrounds the rod is moved into contact with the entrance portion of the center opening in the tubular fastener. The outside diameter of the mandrel is larger than the inside diameter of the center opening in the fastener element. The rod is retracted to cause a reduced thickness wall portion of the fastener element to collapse and form a second radial flange on the second side of the wall. The mandrel is forced axially into the center opening in the fastener element. This causes a tubular end portion of the fastener element that is in the opening in the wall to radially expand into tight engagement with the sidewall of the wall opening. It also cold expands the wall material surrounding the opening for fatigue enhancement of the wall material.
