The present invention relates to a mixture consisting of - 60 to 98 wt.% of a partially crystalline polyamide polymerised from m-xylylene diamine and adipic acid, - 2 to 40 wt.% of an aliphatic polyamide containing inorganic particles with a characteristic particle diameter of less than 800 nm, wherein the proportion of organic and/or inorganic particles in the polymer mixture is less than 10 wt.%...

Solid phase synthesis of oligeonucleotides The invention therefore relates to a process for preparing oligonucleotides by means of solid phase synthesis by a) sequentially synthesizing the nucleotides on a solid support in accordance with known methods, with exocyclic amino groups which are present on the nucleobases being protected by a cyclic diacyl group and with it being possible to eliminate ...

L'invention a pour objet un matériau à base de fibres minérales, dont au moins une partie sont des fibres ~ multi-composantes ~ et dont la cohésion et/ou la géométrie est (sont) assurée(s), au moins en partie, par un encollage. Elle a également pour objet l'utilisation de ce matériau pour l'isolation thermique et/ou acoustique.; Material based on mineral fibres, in which some of the fibres are "mu...

A video signal converter converts a video signal to a required form. The required form of the signal is the display format for displaying the signal. The input signal is converted to a digital signal and stored in a memory using the output of a first clock pulse generator synchronized to the horizontal synchronizing signal of the input signal. The digital signal is read out from the memory using t...

Disclosed herein is a liquid discharging method, comprising using a liquid-discharge head equipped with a discharge opening from which a liquid is discharged, a first region to which a first liquid is supplied, a bubble-generating region containing a second liquid and generating bubbles in the second liquid, and a movable member which is displaceable between a first position opposite to the bubble...

Disclosed are novel branched cyclodextrins having an N-acetylglucosaminyl, glucosaminyl, N-acetylgalactosaminyl group or galactosaminyl group bonded to a hydroxyl group of a cyclodextrin ring by .beta.-bonding and their salts. The novel branched cyclodextrins are produced by reacting a cyclodextrin with an N-acetylglucosamine or N-acetylgalactosamine using an enzyme such as N-acetylhexosaminidase,...

Improved hydrogenation catalysts consisting essentially of highly dispersed, reduced ruthenium and rhenium on carbon support and methods of making and using the same. Such catalysts exhibit high conversion rates in aqueous solution hydrogenation of hydrogenatable precursors (e.g., maleic acid, succinic acid, gamma -butyrolactone, etc.) to tetrahydrofuran, 1,4-butanediol and mixtures thereof.

The panel has an air inlet opening (2) at the bottom. The incoming air (10) may be forced in by a pump or fan (14). There is a closed sheet or housing (1) at the front, made of a transparent layer followed by an opaque layer designed to trap light and solar energy. Air impelled by the pump may flow up the tapered channel between this housing and the front of a porous block (8) of non-transparent m...
