Abstract: A device and method for permitting the separation of plasma or serum from whole blood. The device comprises a matrix of hydrophilic sintered porous material to which at least one red blood cell agglutinating agent has been applied. According to a first method of using the device, a sample of whole blood is applied to a first end of the matrix and the red blood cells within the sample come in contact with the agglutinating agents present in the matrix. The blood cells agglutinate, and are entrapped in the interstices of the matrix, while substantially blood-cell-free serum or plasma accumulates near the outlet of the device. A filter means in liquid receiving relationship with the matrix functions to wick the serum or plasma from the matrix. 
     According to an alternative aspect of the invention, a filter means in liquid receiving relationship with the outlet of the matrix functions to retain any blood cells which pass through the matrix as the filter means wicks the plasma or serum from the matrix. Additional agglutinating agents may be incorporated within the filter means to facilitate retention of blood cells which pass through the matrix. 
     Another aspect of the present invention involves a device for the measurement of a serum or plasma sample,   utilizing a matrix of sintered porous material, such as sintered glass, sintered steel, sintered ceramics, sintered plastics, and eguivalents thereof. The matrix is characterized by a reproducible fluid uptake capacity proportional to the fixed dimensions of said matrix, a minimal reactivity with plasma or serum components, and a hydrophilic internal surface which enables the matrix to collect and retain a predetermined volume of sample for analysis. 
     A further aspect of the present invention provides a porous reagent delivery system comprising a matrix of sintered porous material containing at least one reagent in a freeze-dried state, and method for making same. The system allows the delivery of a unitized form of a freeze-dried reagent which is recoverable upon contact with a liquid.

Abstract: Determination of the formula of genomic DNA, i.e. genome sequencing, by a hybridization with oligonucleotide probes (YU Patent Application 570/87) envisages the use of 100000 oligonucleotide probes and the same number of hybridizati­ons with 6000000 of addressed sample-clones on filters in order to determine contents of oligonucleotide sequences in each clone. The process presents improvements in preparati­on of samples for hybridization and improvements which enable one to follow gene expression by determining partial or complete fragment sequences of genomic DNA, mRNA or cDNA. By binding fragments of genomic DNA to discrete particles (DP) of a microscopic size which are recognizable in a step of reading experimental image, the necessity for addressed samples on filters is dispensed with and this drastically reduces automatical-robotical component of the process and allows miniaturization of the entire method from a level of industrial installation to the level of laboratory instrument. Processes for binding DNA fragments to DPs recognizable in common reactions, allow elimination of cloning, i.e. DNA amplification in the host cells and, in a process of library forming, need for formation of 6000000 addressed samples in any one of the phases of a process for sequencing by hybridization.

Abstract: One or more streams of molten metal poured into a continuous casting mold (1) are acted on magnetically by static magnetic fields, covering substantially the entire width of the casting mold (1), thereby reducing the speed of the molten metal streams from the immersion nozzle (2), unifying the flow profile of the molten metal in the mold (1), preventing trapping and accumulating of mold powders and inclusions into the cast products. Magnetic poles (3) are provided which are at least as wide as or wider than the minimum width of the cast products and the iron core (F) is arranged on the same face of the casting mold (1) with mutually opposite polarities in the drawing direction. Even if casting conditions change from time to time, defects in final products made of the cast metal are substantially reduced.

Abstract: Analytical reaction cassette and method for performing sequential analytical assay procedures to determine the amount of an analyte in a liquid test mixture. The reaction cassette (10) can be in the form of a substantially square container having a substantially horizontal axis of rotation and incorporated with one or more analytical reagents such that they are contacted with a liquid test mixture in a desired ordered sequence to perform a particular assay procedure. Corners (22-24) provided by the substantially square configuration of the reaction cassette disrupt the flow of liquids disposed in the reaction cassette upon contact therewith to thereby agitate and mix such liquids. A liquid disposed in the reaction cassette is capable of being manipulated and mixed therein by rotating the reaction cassette about the horizontal axis at sufficiently low velocities wherein the transport of such liquid is noncentrifugal and due substantially only to gravitational force. The reaction cassette is particularly useful for performing immunoturbidimetric assays, e.g., for the determination of glycated hemoglobin.

Abstract: The invention relates to a method and an apparatus for nondestructive testing of superficial layers, in particular of large construction pieces having complicated shape. Objects to which the invention relates are mechanical engineering, and plant and equipment construction pieces. In the method, the laser pulse is split, according to the invention, into two spatially separated subpulses of approximately equal intensity and the focal lines of both subpulses are located on the surface of the construction piece. The spacing between the two focal lines is adjusted by moving the beam splitter or individual components of the beam splitter or the like along the optical axis to an extent which depends on the geometry of the construction piece, the frequency of the ultrasonic waves and the attenuation and is kept constant for subsequent measurements. The method is carried out in an apparatus in which, according to the invention, a beam splitter is situated between the cylindrical lens and the surface of the test piece, an adjustable spacer is situated at the position of the two focal lines to fix the spacings between the beam splitter and the surface of the test piece and the ultrasonic test head is arranged on the continuation of the connecting line between the centres of the two focal lines.
