Abstract: The present application relates to use of Prussian blue nanoparticles in the preparation of a medicament for the prevention, delay or treatment of neurodegenerative disease. The present application finds that Prussian blue nanoparticles have significant effects in the prevention, delay or treatment of neurodegenerative disease. Cell test results show that Prussian blue nanoparticles can reduce the level of ROS in nerve cells stimulated by hydrogen peroxide and increase the proportion of living cells in nerve cells stimulated by hydrogen peroxide. Animal test results show that Prussian blue nanoparticles can significantly reduce the expression level of oxidative stress markers in the hippocampus of mouse models of neurodegenerative disease, and significantly improve the learning and memory abilities and ameliorate motor dysfunction of mouse models of neurodegenerative disease.

Abstract: A computer device has a touch screen which displays game elements. A user is able to move game elements to make a match. When a match is made, the game elements of the match are removed. Each game element is associated with a tile. Each tile either has a cover object or no cover object. Underlying entities are provided which occupy at least two tiles. The device has a processor which is configured to determine on detecting the match game condition if at least one tile of the game elements in the match game condition has a cover object and if so to remove the cover object and subsequently to determine if the underlying entities are only associated with tiles having cover tiles. If not, the underlying entity is repositioned if partially uncovered or removed if completely uncovered.

Abstract: A method for drying high moisture, low calorific value lignite for a generating set and recovering water contained therein and an apparatus thereof mainly consist of a rotary steam tube dryer, a washing cooling tower, a coal mill, a first bag filter, a condenser, a weighing surge bunker, a water ring vacuum pump and so on. A drying system is integrated with a milling system, every dryer and the corresponding coal mill are disposed and are directly connected via a surge bunker, thereby not only saving the heat lost during the transportation of pulverized coal, but also omitting a long-distance transportation from a conventional drying system to a conventional milling system, effectively avoiding such phenomena as dust pollution, waste and spontaneous combustion during transportation and transshipment, simplifying the coal preparation system employed in the front-end process of drying.

Abstract: A dehumidifying tower having a washing section, a flash-distilling section, and a condensing section. In the washing section, exhaust gas is washed with a cooling liquid to remove at least a portion of solid dust entrained in the exhaust gas, cool the exhaust gas, and condense at least a portion of moisture in the exhaust gas into liquid. The flash-distilling section flash-distills the cooling liquid used in the washing section to produce a cooled cooling liquid and a cooling liquid vapor. Cooling liquid produced by flash-distillation enters the washing section. The flash-distilling section is in gas-phase isolation from the washing section. The condensing section condenses the cooling liquid vapor produced by flash-distillation. The condensing section is configured to be in gas-phase communication with and liquid-phase isolation from the flash-distilling section, and be in both gas-phase and liquid-phase isolation from the washing section.

Abstract: The invention relates to an exhaust gas separating tower, comprising a washing section, a flash-distilling section above the washing section, and a liquid seal means between the flash flash-distilling section and the washing section. The washing section is configured for washing exhaust gas entering the tower with a cooling liquid to at least partially remove solid dust entrained in the exhaust gas, cool the exhaust gas, and condense at least a portion of moisture in the exhaust gas into liquid. The flash-distilling section is configured for flash-distilling the cooling liquid from the washing section to produce a cooled cooling liquid and a cooling liquid vapor. The liquid seal means is configured so that the cooling liquid produced by flash-distillation can enter the washing section through the liquid seal means while the flash-distilling section is in gas-phase isolation from the washing section, wherein a pressure in the flash-distilling section is lower than that in the washing section.
