Abstract: A belt cleaning device for a coal loading and unloading belt conveyor, including a split-type spraying pipe, a first alloy scraper, and a second alloy scraper. The first alloy scraper is provided on the belt, the belt is supported by a roller. The second alloy scraper is elastically pushed against an underside of the belt and suspended below the roller. A material scraping area is covered by the split-type spraying pipe, the split-type spraying pipe is configured to spray water onto the material scraping area. The belt cleaning device can independently control the inclination angle of the first alloy scraper and the second alloy scraper and uniformly control the adhesion force between the alloy scrapers and the belt, thus solving the problem of scraping off adhesive materials at different wear rates of the belt, improving the efficiency of the coal loading and unloading belt conveyor, and reducing maintenance needs.

Abstract: A display control method and an apparatus are provided. The display apparatus includes a controller, a display module, and a light-transmitting module. The controller is configured to: in a two-dimensional display mode, control the display module to display a first two-dimensional image, and control the light-transmitting module to be in a first light-transmitting state, so that the display apparatus displays the first two-dimensional image; and in a three-dimensional display mode, control the display module to display a second two-dimensional image, and control the light-transmitting module to be in a second light-transmitting state, so that the display apparatus displays a naked-eye three-dimensional image. The first light-transmitting state is different from the second light-transmitting state; and in the second light-transmitting state, a lens layer and a grating layer are formed on the light-transmitting module.

Abstract: Disclosed are a split bristle and a cleaning brush having the split bristle. The split bristle includes a bristle body having a main body part and plural cleaning parts installed at the same end of the main body part, and the cleaning part is formed and protruded from an end of the main body part and the cleaning part has an outer diameter smaller than half of the outer diameter of the main body part. In actual use, a free end of the leaning part touches a user's skin to be cleaned. With the special structure of the bristle body, the cleaning part can be used to clean the pore dirt on the user's skin effectively, so as to improve the efficiency and effect of cleaning the user's skin by the bristle body.

Abstract: Rhein analogues that exhibit anti-proliferative activity, particular against cancer cells, are described herein. In some embodiments, the compounds contain a flat or planar ring system. Such rings system by facilitate non-covalent binding of the compounds to the DNA complex, such as by intercalation. In some embodiment, the compounds contain a flat or planar ring system as described above and one or more substituents which are alkylating moieties, electrophilic groups or Michael acceptors or groups which contain one or more alkylating moieties, electrophilic groups and/or Michael acceptors. The compounds described herein can also contain one more functional groups to improve the solubility of the compounds.

Abstract: Materials containing pharmaceutically active species in solid (e.g., crystal) form, and related methods, are provided, allowing for improved stability, solubility, bioavailability, and/or dissolution rates for pharmaceutically active species having poor aqueous solubility.
