Abstract: A method for making a composition for enamel regeneration proposes to encapsulate soluble calcium and phosphate salts within corresponding internal water phases in respective water-in-oil-in-water emulsions stabilized by solid particles, and add them to a toothpaste, enamel restoring gel or mouth wash base. In this way, the soluble calcium and phosphate salts can be present stably in the toothpaste, enamel restoring gel or mouth wash over a long period of time. When the toothpaste, enamel restoring gel or mouth wash of the present disclosure is used in oral cavity, the water-in-oil-in-water emulsions rapture under the effect of friction and pressing, releasing the soluble calcium and phosphate salts encapsulated within the corresponding internal water phases. As a result, the liquid in the user's oral cavity will contain high concentrations of calcium and phosphate ions, which can enhance the rate of enamel remineralization.

Abstract: Disclosed is a multi-section non-pillar staggered protected roadway for a deep inclined thick coal seam (DITCS) and a method for coal pillar filling between sections. The multi-section non-pillar staggered protected roadway includes a floor, a coal seam, an immediate roof, and a basic roof in a multi-section coal seam, where the floor is disposed below the coal seam, a hydraulic support is disposed in a section between the floor and the immediate roof; a return airway and a transportation roadway are respectively disposed on a left side and a right side of each section; the return airway and the transportation roadway in each section are communicated with each other through a working face; and non-pillar staggered layout is used for a return airway of a next section and a transportation roadway of a current section.
