A system for protection, control, metering, and monitoring of the delivery of electrical power is disclosed. Embodiments of the system provide input / output devices called bricks to receive analog and binary field data from primary equipment located in a power substation switchyard. The bricks are linked via fiber-optic patch cables and patch panels with one or more intelligent electronic devices (“IEDs”). In operation, the bricks convert the received binary and / or analog field data into digital signals, and transmit the digital signals synchronously to their associated IEDs using clock signals provided by each IED to the individual bricks. The bricks may accept a computer software code download from each of its master IED(s). Multiple code implementations, each tailored to the requirements of its master IED(s) can therefore co-exist on a single brick.

An article includes a piece of encapsulated insulation including an envelope having at least two vents therethrough, a particulate insulation within the envelope, and a porous filter overlying each vent of the envelope. The porous filter has a mesh size no larger that the minimum size of the particles. The article may further include a structure having a structure surface, and the piece of encapsulated insulation overlies and covers at least a portion of the structure surface.

Methods for correcting inhomogeneities of magnetic resonance (MR) images and for evaluating the performance of the inhomogeneity correction. The contribution of both transmit field and receiver sensitivity to signal inhomogeneity have been separately considered and quantified. As a result, their negative contributions can be fully corrected. The correction method can greatly enhance the accuracy and precision of MRI techniques and improve the detection sensitivity of pathophysiological changes. The performance of signal inhomogeneity correction methods has been evaluated and confirmed using phantom and in vivo human brain experiments. The present methodologies are readily applicable to correct signal intensity inhomogeneity artifacts produced in different imaging modalities, such as computer tomography, X-ray, ultrasound, and transmission electron microscopy.

A dielectric layer (e.g., an interpoly dielectric layer) is deposited over low and high voltage devices of a peripheral memory device. The dielectric behaves as an oxidation and wet oxide etch barrier. The dielectric prevents the devices from being stripped by a wet oxide etch that can result in the exposure of the silicon corners. The exposure of a silicon corner may increase thinning of a gate oxide at the field edge. This causes variability and unreliability in the device. The dielectric is not removed from a device until the device is ready for processing. That is, the dielectric remains on a device until the growing of a gate oxide on that device has begun. This reduces the exposure of the silicon corner. Hedges that result may be removed by exposing a trench in the field oxide at the hedge.

The invention discloses a novel screening method of anticancer medicaments. The novel screening method is characterized by comprising the followinh steps of: (1) preparing TTLL12 overexpressed Hep-2 cell lines; (2) selecting positive control and negative control medicaments; (3) obtaining the optimum concentration of nitrotyrosine and the optimum diluted concentrations of medicaments to be detected; and (4) screening the medicaments, finally checking readings and comparing. The novel screening method of the anticancer medicaments disclosed by the invention has the characteristics that the method is simple, a user only needs to master a cell culture and Elisa (Enzyme-linked Immuno Sorbent Assay) technology and then masters the law, the method is fast and cheap, the method is few in reagents and variation factors, stable, high in sensitivity, good in specificity, easy to popularize and capable of screening in a large scale. Furthermore, through the experiment, whether the medicaments to be detected have anti-cancer effects and anticancer effect mechanisms of the medicaments to be detected simultaneously can be obtained, so that the speed of clinically applying the medicaments to be detected is greatly accelerated, and more lives of patients are expected to be saved.

The present invention provides an improved process for the production of recombinant peptides. In particular, the present invention provides an improved process for the production of recombinant peptides in the form of viral capsid fusion proteins which can be assembled in vivo in plant cell suspension cultures.

A method of system design, and more particularly a method of designing systems that achieve a set of performance goals using a hierarchically partitioned system representation wherein performance simulations are performed at multiple levels within the hierarchy and are combined to simulate a system level result in order to reduce the aggregate time required for performance simulation.

The present invention describes a catalyst support, which is used as an inorganic carrier for a Ziegler-Nata catalyst (ZN), using a modified spray cooling method. Such a catalyst support is prepared from alcoholic solutions of (a) an inorganic compound, in which the inorganic compound is a magnesium compound and (b) an inorganic compound and one or more additives. The solutions are prepared at a temperature below 100° C., carried through a nozzle placed inside a reactor, and sprayed into droplets forming a solid precipitate, which is generally spherical, when in contact with an inert hydrocarbon solvent at low temperature. The obtained catalyst support is reacted with a titanium compound, preferably titanium tetrachloride, in order to produce an active catalyst for olefin polymerization.
