摘要:
The present invention concerns a method for improving plant growth characteristics by increasing expression in a plant of a nucleic acid encoding a CCS52 protein and/or by increasing level and/or activity in a plant of a CCS52 protein. The invention also relates to transgenic plants having improved growth characteristics, such as increased plant size, increased organ size or increased number of organs, which plants have increased expression of a nucleic acid encoding a CCS52 protein.

The invention relates to inclusion complexes of 3-morpholino-sydnonimine or its salts or its tautomer isomer, process for the preparation thereof and pharmaceutical compositions containing the same.The inclusion complex of 3-morpholino-sydnonimine or its salt formed with cyclodextrin derivative is prepared bya) reacting the 3-morpholino-sydnonimine or its salt in an aqueous medium with a cyclodextrin derivative and the complex is isolated from the solution by dehydratation, orb) high energy milling of 3-morpholino-sydnonimine or its salt and a cyclodextrin derivative.
摘要:
The invention relates to synergistic antiphlogistic pharmaceutical compositions comprising a pyrido [1,2-a]-pyrimidine derivative of the Formula I ##STR1## wherein R.sup.1 and R.sup.2 are lower alkyl and R.sup.3 stands for lower alkoxycarbonyl or carbamoyl and the dotted line represents an optionally hydrogenated band or a salt or quaternary salt thereof and 1-[p-chloro-benzoly]-2-methyl-5-methoxy-indolyl-3-acetic acid of the Formula II ##STR2## The advantage of the compositions is that as a result of the synergistic activity of the compound of the Formula I, the antiphlogistic Indomethacin of the Formula II can be administered in a significantly lower doses and consequently the unfavorable side effects of the latter compound are mitigated.

The gene asnA which encodes a prokaryotic ammonium-specific asparagine synthetase (ASN-A) can be introduced into plant cells. Such transformed cells and plants developed therefrom not only tolerate glutamine synthetase inhibitors but are effectively stimulated by such herbicides.
摘要:
An improved linear guiding mechanism with a standing part and a moving part which have respective uniform cross sections. A pair of spaced guiding channels is formed between these parts and respective linear ball bearings are arranged in both channels that interconnect the two parts. The channel walls are abutting the balls via steel bars extending along the channels. Preferably the standing part defines a cylinder in which a piston is moved and its shaft is connected to the moving part. The parts are made of light and soft material such as aluminum or plastic and manufactured by extrusion technique. The rather high variation of dimensions of such parts are compensated by means of biasing forces that press the channels together, and the biasing forces are sufficiently high to resist operational load. The length of the ball bearings is at least the half of the maximum stroke.
摘要:
The subject of the invention is a valve for universal utilization and several purposes allowing by its formation the relatively high flow in the basic state and slightly open state of the valve even in case of small pressure differences in case of low pressure; furthermore the formation of the valve allows to ensure providing functions depending on the direction of flow that in given case can be regulated regarding back-pressure, partial back-pressure, pressure relief, partial relief limiting functions.The valve according to the invention is made in one piece from a soft, flexible material, and it has a full cross-sectional open basic part (2) at one end, and an intermediate part (3) of decreasing cross-section joining the said basic part (2), as well as a flattened part (4) joining the intermediate part (3) in the other end of the valve (1). It is characterized by that, the flattened part (4) is a structure sintered or pressed or glued in the material of the valve (1), and on the flattened part (4) of the valve (1) a pressed rim (7) made by airtight fixing of the edges of the flattened part (4), preferably by sintering, or pressing or glueing is formed, furthermore the length (L) of the intermediate part (3) is L=0,5 . . . (K/π), compared to perimeter (K) in the basic part of the valve (1), in connection with the medium in motion, and the length (N) of the pressed rim (7) in the basic part of the valve (1) compared to perimeter (K) in connection with the medium in motion is N=0,1 . . . 2 (K/π).
