摘要:
Described is a process for making closed cell fluoropolymer foam, and the foam so made. The process includes subjecting a fluoropolymer resin an inert gas at a pressure higher than atmospheric to drive gas into the resin, raising the temperature of the resin to or above its softening point, and reducing the pressure while maintaining the temperature at or above the softening point of the resin, in order to expand the resin to result in closed cell fluoropolymer foam. The resin is cross-linked prior to expansion. The resulting foams can be used in various applications, such as in flotation devices and for making thermal and/or acoustic insulation.

Interdigitated electrode arrays are very promising devices for multi-parameter (bio)sensing, for example the label-free detection of nucleic acid hybridisation for diagnostic applications. The current disclosure provides an innovative method for the affordable manufacturing of polymer-based arrays of interdigitated electrodes with μm-dimensions. The method is based on a combination of an appropriate three-dimensional structure and a single and directional deposition of conductive material. The three-dimensional structure can be realized in a polymer material using a moulding step, for which the moulds are manufactured by electroplating as a reverse copy of a silicon master structure. In order to ensure sufficient electrical isolation and individual, but convenient, accessibility of the sensors in the array, the interdigitated electrode regions need to be complemented with specific features on the three-dimensional structure. Combined with the use of e.g. shadow masks in the deposition step, these features allow for the site-specific deposition of the conductive material. The technology described has the additional advantage to integrate highly miniaturized and arrayed electronics elements into polymer micro-fluidics technology, which leads to the affordable manufacturing of (bio)sensor arrays.

Closed cell polyamide foams are prepared by subjecting a polyamide resin to inert gases at an elevated pressure and at a temperature above the softening point of the resin and reducing the pressure while the temperature is maintained above the softening point of the resin, resulting in expansion of the resin.

A speech signal is decoded by a vocoder and the reconstructed speech samples are provided to a decoded frame check unit. The decoded frame check unit examines the energy of the reconstructed speech and compares the energy of the reconstructed speech to a range of acceptable energy values. If the energy is not within the range of energy values, a frame erasure is declared and the decoded frame is prevented from being to the speaker in the telephone. In the exemplary implementation, the speech is reconstructed by a vocoder which includes a postfilter which in turn includes automatic gain control. The automatic gain control element of a post filter includes a means for measuring the energy of the decoded speech data. This measured energy is used by the decoded frame check unit to decide whether to provide the decoded data to the user or to declare a frame erasure. This implementation reduces the amount of additional hardware necessary to implement the present invention.

Described are methods and mechanisms for providing application support in a multi-processor system including receiving a request to execute an application, identifying a property specifying which processor from a plurality of processors to utilize to execute the application that is associated with the application, scheduling the application for execution on the specified processor based on the identified property, loading the application responsive to the scheduling of the application, and executing the application utilizing the specified processor.
摘要:
The present invention relates to codon optimised polynucleotides which are efficiently expressed in mammalian cells and encode insect proteins from Dermaphagoids dust mite. In particular, the optimised codon polynucleotides encode a protein from Dermaphagoides pteronyssinus, such as DerP1 or proDerP1. The present invention also provides methods of preparing pharmaceutical compositions comprising the expression of the codon optimised polynucleotides, and vectors and transformed host cells comprising them.
摘要:
A method of sterilizing an article includes placing the article into a chamber containing an inner atmosphere and exhausting the inner atmosphere to lower pressure in the chamber. Hydrogen peroxide vapor is present in the chamber during at least a portion of the step of exhausting the inner atmosphere. Exhaustion of the inner atmosphere is terminated and additional hydrogen peroxide is admitted into the chamber. Hydrogen peroxide vapor contacts the article for a sufficient period to effect sterilization of the article.
摘要:
A method and an apparatus for sterilizing a lumen device. A lumen and a container having an interface on a wall of the container are enclosed in a chamber. The lumen is placed across the interface so that one end of the lumen is in the container and the other end is in the chamber. Germicide is introduced into the chamber, and a pressure difference is created between the two ends of the lumen, so that the germicide flows through the lumen. The lumen may alternatively be placed across an interface which separates the chamber into two areas. Germicide is introduced into the chamber, and a pressure difference is created between the two areas of the chamber, causing the germicide to flow through the lumen.

The present invention relates to a process for sterilization of medical instruments by concentrating a sterilant such as hydrogen peroxide inside of a sterilization chamber and sterilizing articles therewith. The sterilant is concentrated by removing more water from the sterilization chamber than peroxide.

The present invention relates to a process for sterilization of medical instruments by concentrating a sterilant such as hydrogen peroxide inside of a sterilizer and sterilizing articles therewith. This concentrating process is monitored by determining the concentrations of water and peroxide in the chamber.
