A shoot of a plant is cultivated under the presence of glutathione, so that the shoot is rooted. It is possible to cultivate the shoot under the presence of glutathione by use of a rooting medium including glutathione or by contacting a solution including glutathione with the shoot. Oxidized glutathione is preferably used as glutathione. By promoting rooting of the shoot of the plant, a rooting rate of the shoot of the plant is improved. This improves productivity of a clone seedling.

Method for producing clone seedlings

A thermally-sensitive recording medium having a protecting layer formed on a thermally-sensitive recording layer containing a colorless or pale-colored electron-donating leuco dye and electron-accepting color-developing agent. The thermally-sensitive recording layer is formed on a substrate, and the protecting layer contains a resin that contains a carboxyl group, epichlorohydrin resin and modified polyamine/amide resin, and the thermally-sensitive recording medium exhibits sufficient resistant against water such as rain or humidity, and further is excellent in printing run-ability (head debris and sticking) and sensitivity.

Thermally-sensitive recording medium

An apparatus for purifying BOD-containing water by the action of activated sludge, which includes a vessel for containing activated sludge-containing liquid, and an aerator which is installed in the vessel. The aerator has a bubbler which successively takes out the liquid in the vessel for causing the liquid to absorb oxygen, and a settler which calmly returns the oxygen-rich liquid into the vessel.

An apparatus for enriching dissolved oxygen in water which comprises a plurality of dissolving devices, each of which comprises: (a) a pair of vertically arranged tubular bodies, the lower end of the first tubular body being provided with an inlet through which raw water is introduced and the lower end of the second tubular body being provided with an outlet for discharging oxygen enriched water; (b) a tube connecting the interior of both tubular bodies at the central portions thereof; (c) a bubbler disposed in the interior of the first tubular body for flowing an oxygen enriched gas into the raw water and for moving the raw water into the second tubular body through the connecting tube; (d) a pipe for connecting the top portions of the tubular bodies which form a chamber for the gas above the liquid level of the raw water in each of the tubular bodies; (e) a means for supplying an oxygen enriched gas into the chamber in the second tubular body; and (f) a means for supplying the gas in the chambers to the bubbler.

Apparatus for enriching oxygen contained in water

A process for eliminating sulphur oxides from combustion exhaust gases, comprising the steps of dividing the combustion exhaust gases into a first stream and a second stream, and passing the first stream through a first activated carbon bed which was previously washed with water, thereby drying the activated carbon, cooling the first stream, and removing a substantial portion of sulphur oxides from the first stream by adsorption. The treated first stream is mixed with the second stream and together passed through a second activated carbon bed which was previously dried, thereby removing sulphur oxides by dry adsorption. A third activated carbon bed which was previously used in the dry adsorption step is washed with water, removing the previously adsorbed sulphur oxides therefrom. Each of the first, second and third activated carbon beds are cyclically treated by the drying, dry adsorption and washing steps.
