Abstract: Straw bales (4) are used in conjunction with a skeletal framework (16, 52 or 82) to form various structurally stable building components such as walls and floors. Straw bales (4) and horizontal trussing members (6, 18 or 60) are combined to form a truss (8). The truss (8) has a pair of trussing members (6, 18 or 60) operatively connected to one or more bales (4). The trussing members (6, 18 or 60), which are positioned opposite one another along the edges of the bale (4), form the chords of the truss (8). The bales (4) form the web of the truss (8). The trussing members (6, 18 or 60) are one of the basic components of the skeletal framework (16, 52 or 82) used to construct the various composite structures embodying the invention. In the composite structures, straw bales (4) are arranged in layers within a skeletal framework (16, 52 or 82). The skeletal framework (16, 52 or 82) includes the trussing members (6, 18 or 60) and a series of rods (20 or 54) positioned along the center line of the layered bales (4).

Abstract: A MicroColonylmager instrument and solid phase methods to screen cells expressing mutagenized enzymes for enhanced activity. The MicroColonylmager instument and methods permit high throughput screening of enzyme libraries by time course analyses of single-pixels, using either absorption, fluorescence or FRET. This high throughput assay can detect small differences in enzyme rates within microcolonies grown at a nearly confluent density on an assay disk. Each microcolony is analyzed simultaneously at single-pixel resolution, requiring less than 100 nl substrate/measurement. By simultaneously assaying different substrates tagged with spectrally distinct chromogenic or fluorogenic reporters, the substrate specificity of an enzyme can be changed.

Abstract: A process for the recovery of copper and nickel from a copper and nickel sulphide concentrate in slurry form. The slurry is subjected to a biological oxidation turning the copper sulphide to soluble copper sulphate and the nickel to nickel sulphate. The liquid containing the sulphates is separated from the slurry and treated with a solvent extraction reagent so that copper ions are exchanged by the reagent for hydrogen ions to produce a raffinate which is high in sulphuric acid and low in copper sulphate. The solvent extraction reagent is then stripped from the raffinate with a sulphuric acid solution. Copper is electrically harvested from the sulphuric acid solution and a portion of the copper depleted raffinate is returned to form a slurry with additional ore for subsequent biological oxidation. Nickel is recovered from the remaining portion of the raffinate. The preferred bacterium is at least one of Thiobacillus Ferro-oxidans, Thiobacillus Thio-oxidans, Leptospirrilum Ferro-oxidans, Thiobacillum Caldus, Acidimicrobium and Sulpholobus.

Title: Automatic cooking control method for a microwave oven
Inventor: SHON JONG-CHULL
IPC: F24C7/08
Filed: 2000-01-13
Granted: 2003-04-15
Abstract: An automatic cooking control method for a microwave oven using data pattern of food, including the steps of: (a) collecting data outputted from a data detecting section for a predetermined time; (b) comparing the collected data with at least one prestored data pattern; and (c) selecting the data pattern among the prestored data pattern that is most similar with the collected data, and performing a cooking operation corresponding to the selected data pattern. When the data collected for the predetermined time corresponds to a no-load pattern, the microwave oven stops the cooking operation. Without separate external data input about weight or physical status of the food in the cooking chamber, the microwave oven automatically selects the most proper cooking process for the food in the cooking chamber by comparing the data about the food in the cooking chamber with the data patterns of the various foods prestored in the microwave oven. Accordingly, the microwave oven becomes easy to operate, and the cooking quality of the microwave oven is improved. Further, by regularly repeating the data collecting, data pattern comparing, and data pattern selecting processes, the microcomputer can perform the proper cooking operation while adjusting the cooking operation in accordance with the respectively selected cooking operations.  Thanks to the regular repetition of the above processes, the microwave oven can perform the most proper cooking operation in accordance with the present status of the food in the cooking chamber.

Abstract: L'invention concerne un procédé et un appareil permettant d'extraire un cryoprotecteur d'échantillons cryoconservés. Selon ledit procédé, on extrait le cryoprotecteur en utilisant la turbulence et la dispersion convective se produisant autour des cellules, à l'intérieur du récipient primaire de cryoconservation. La dispersion convective est produite par l'action combinée de la gravité et de l'écoulement pulsatoire transmembranaire de tampon à travers les pores de récipients fabriqués à partir d'un matériau pour membranes approprié. L'utilisation de forces mécaniques pour assister le processus de l'extraction du cryoprotecteur permet de conserver les avantages d'une extraction lente de cryoprotecteur tout en ayant un temps d'extraction réel nettement réduit.

Abstract: A system for processing a speech signal to enhance signal intelligibility identifies portions of the speech signal that include sounds that typically present intelligibility problems and modifies those portions in an appropriate manner. First, the speech signal is divided into a plurality of time-based frames. Each of the frames is then analyzed to determine a sound type associated with the frame. Selected frames are then modified based on the sound type associated with the frame or with surrounding frames. For example, the amplitude of frames determined to include unvoiced plosive sounds may be boosted as these sounds are known to be important to intelligibility and are typically harder to hear than other sounds in normal speech. In a similar manner, the amplitudes of frames preceding such unvoiced plosive sounds can be reduced to better accentuate the plosive. Such techniques will make these sounds easier to distinguish upon subsequent playback.

Abstract: Lost transmission packets are recovered using parity symbols. An encoder uses an input file of data and a key I selected from a key alphabet much larger than the number of input symbols in the input file to produce output symbols which might for example constitute entire transmission packets.    An output symbol with key I generated by determining a weight, W(I), for the output symbol to be generated, selecting a number W(I) of the output symbols associated with the output symbol according to a function of I, and generating the output symbol's value B(I) from a predetermined valve function F(I) of the selected W(I) input symbols so that erasures can be recovered without grouping input symbols into blocks. An encoder can be called repeatedly to generate multiple output symbols. The output symbols are generally independent of each other, and an unbounded number (subject to the resolution of I) can be generated, if needed. A  decoder receives some or all of the output symbols generated. The number of output symbols needed to decode an input file is equal to, or slightly greater than, the number of input symbols comprising the file, assuming that input symbols and output symbols represent the same number of bits of data.
