Abstract: Systems, methods and apparatus are included that are configured to model microvascular obstruction (MVO) in patients. According to one aspect of the present disclosure, a multi-scale model is configured to mimic myocardial microcirculation of coronary vessels. The model includes collaterals configured to provide alternative pathways possibly bypassing the MVO, and configured to model coronary artery compliance for spatially resolved fluid transport through the coronary vessels. The model is configured to simulate the MVO by increasing flow resistance in at least one of the modelled coronary vessels, or by blocking the at least one of the modelled coronary vessels completely. The model is also configured to mimic behavior of fluid transport in the coronary vessels during diagnostics or treatment, to design and optimize therapy protocols for the MVO.

Abstract: The invention relates to a method for producing molecule libraries at predetermined locations on a substrate surface by means of sequential chemical reactions involving the use of combinatorial sealing matrices. The topological structures applied to the sealing matrices cover individual areas of the substrate surface in a defined order thereby preventing different partial areas of the substrate surface from undergoing chemical conversions. Several sealing matrices having different topological relief structures can be used in a number of reaction cycles for the synthesis of molecule libraries consisting of complex chemical compounds. The sealing matrices are made of an elastic material such as polydimethylsiloxane. The synthesis involves the use of simple and highly optimized standard methods and standard chemicals of the solid phase synthesis. The reaction rate is accelerated by carrying out the reaction steps in a microfluidic flow-through system.

Abstract: The invention relates to a method for highly parallel production of complex molecule libraries on the surface of a substrate with the aid of regeneratable matrix dies. According to prior art, the production of molecule libraries on a support is expensive, and requires a lot of time and a large amount of apparatus. By using regeneratable matrix dies it is possible to simplify and accelerate the production of molecule libraries, especially DNA and protein libraries, in a significant manner. The matrix-10 die is made of an elastic material such as polydimethylsiloxane and includes locally-bound matrix molecules on the surface thereof, said molecules being used as a model for the synthesis of copy molecules. The copy molcules are transferred to the target surface by means of a contact printing method. The matrix molecules remain on the die for further synthesis and print cycles which can repeated several times. The inventive method is suitable for copying and reproducing differently produced molecule arrays.

Abstract: A feeder device for feeding animals with food product includes a housing divided into a plurality of compartments with individual pivotable bottom walls and an operating system mounted on the housing to control opening of the bottom walls to release the food product contained therein. The operating system includes a locking mechanism located adjacent each bottom wall to releasably secure it in a closed position. An opening mechanism successively activates the locking mechanisms and opens the bottom walls. A timer device including an electronic controller and a limit switch electrically coupled to the opening mechanism controls the operation of the latter at the beginning of a pre-determined time interval. The limit switch is activated by the opening mechanism and stops operation of the opening mechanism during the pre-determined time interval.

Abstract: A method for fabricating silicone elastomer stamps with hydrophilic surfaces is provided. The concept of polymer grafting is used to produce the stamps. The stamps thus produced have the great advantage that grafting of a thin hydrophilic polymer on a hydrophobic PDMS surface can render PDMS stamps permanently hydrophilic. With such stamps it becomes possible to print aqueous or highly polar inks reproducibly over days and weeks.

Abstract: A method and also a device is proposed for identification of a substance, preferably comprising biochemical molecules. In a first step a probe and said substance will be brought into contact, afterwards in a second step the probe and said substance will be withdrawn from each other, while measuring the value of at least one physical parameter characterizing the interaction between said probe and said substance and comparing said measured value with a reference value for identification.

Abstract: For a point-of-sales rug selection from a stack thereof, a method of working a raised stack from the bottom up so that a rug assuming successively the bottom position is permitted to descend, each in turn, to a floor display position and, after the first descent using lowering cables, the cables having a length portion in a taut vertical condition to serve as tracking guides for the vertical descent by gravity of successive rugs.

Abstract: In the jet straying of ink droplets in a decorative pattern onto a fabric during which a jet spray head shuttles across the fabric changing directions at opposite selvage edges, the provision in an interposed position between the spray head and upstanding selvage edge fibers of shields preventing contact therebetween which maintains bubble closures over exit openings in the jet spray head intact and obviates inadvertent gravity flow of ink as might mar the decorative pattern.

Abstract: The removal of albedo in the preparation of a citrus fruit for consumption, in which a known aqueous solution of pectinase enzyme is used for its known albedo-removal function, but in the present circumstances a vacuum is used to primarily draw the pectinase enzyme to the interface of the albedo and the citrus fruit and only nominally to the interface of the albedo and the peel of the citrus fruit, so that removal of the peel carries with it the albedo and uncovers the citrus fruit in a desirable albedo-free condition.

Abstract: A method is provided for masking a crack in a drywall or plaster surface of a dwelling, comprising the steps of die cutting a repair patch from a heat-shrinkable plastic film of a defined size presenting a surface area adapted to be placed in covering relation over the crack and bounded about its periphery by surrounding edges. The patch is prepared with an adhesive confined to the surrounding edges only and is placed over the crack making an initial attachment to the drywall and heat is applied to the patch, to cause a contraction in size of the patch while exerting a pressure normal in size in the patch.

Abstract: A covering over the 90 degree corner of gypsum or plasterboards which rounds the corner to a small radius and thus provides a desirable commercial appearance thereto, which uses heat shrinkable tape to fuse the covering in place and also, as a result of the shrinkage, cause the removal of any wrinkles therein as might otherwise undermine the objective of the covering.

Abstract: The within inventive method for repairing a drywall surface (i.e. gypsum boards) or a plaster wall or ceiling, obviates the need for spackling and contemplates instead the use of a plastic film in covering relation over the surface defect and in this position properly prepared, so that the plastic is totally devoid of wrinkles and in firm attachment to the surface, with the result that the repair cannot be detected from the original surface.

Abstract: A racemic or optically active alkyl 2-chloropropionate is prepared, respectively, from a racemic or optically active alkyl lactate by, in a first step, gradually bringing the alkyl lactate into contact with the thionyl chloride, in the presence of an organic base, while maintaining, in the reaction mixture, an excess of thionyl chloride, relative to the amount of alkyl lactate introduced into this mixture, at a temperature below the decomposition point of the chlorosulphinate of the alkyl lactate, which is formed as an intermediate, and then, in a second step, in heating the reaction mixture resulting from the first step at a temperature which is at least equal to the decomposition point of the chlorosulphinate of the alkyl lactate.The alkyl 2-chloropropionates can be used for the manufacture of the racemic or optically active 2-phenoxypropionic acids.
