An electricity-generating system using solar heat energy comprises: a heat storage tank, a pair of heat-sensitizing units with valves, a steam turbine, a solar collecting system comprising a fixed body in the form of a mesh net having mesh openings, a condenser lens coupled to each of the mesh openings of the fixed body, a condenser unit installed at the bottom portion of the fixed body, which includes a collector lens that increases the concentration of energy focused through the condenser lens and transfers heat to the bottom of the body thereof; a heat storage tank combined with the bottom portion of the fixed body, which heats and stores the heat storage medium by heat energy transferred through the collector lens; a circulation conduit which has an upper plate-shaped coiled tube and a lower coiled circulation tube, which is stacked and contained in the heat storage tank.

Electricity-generating system using solar heat energy

A use method of agmatine or a pharmaceutically allowable salt thereof, and a pharmaceutical composition comprising the same are disclosed. The method and pharmaceutical composition of the present invention can effectively cure or prevent eye diseases preferably including glaucoma, retinopathy, and optic neuropathy associated with apoptosis in retinal ganglion cells (RGCs), particularly hypoxia-induced or tumor necrosis factor-&#x3b1; (TNF-&#x3b1;)-induced apoptosis.

Use of agmatine for protection of retinal ganglion cells

Disclosed is a mass transfer vessel or a mass transfer tower, which is installed in water purification equipment, condensate water demineralization equipment, sewage treatment equipment, waste water treatment equipment, or chemical reactors to perform filtration, adsorption, ion exchange, regeneration of an ion exchange resin, chemical reaction, and spray of a chemical cleaning solution, and more particularly to a method for designing radial distributors in a mass transfer vessel, which uniformly distribute influent flow quantity into all cross sections so as to improve the efficiency of a mass transfer process, such as filtration, adsorption, ion exchange, a chemical reaction process, and a chemical cleaning process.
