The present invention relates to methods for predicting a risk of cognitive deterioration, monitoring progression of cognitive deterioration and diagnosing cognitive deterioration in a patient. The present invention further relates to methods for diminishing progression rate of cognitive deterioration in a patient by lowering brain iron levels in the patient or lowering CSF ferritin levels in thepatient.

The invention provides a poor hematite grading level and narrow level sorting process, which is characterized in that three levels of products can be obtained by using a double-section cyclone to grade and reselect a primary ore grinding product and are respectively fed into subsequent selection work to realize grading level and narrow level sorting. The poor hematite grading level and narrow level sorting process comprises the specific steps of: (1) grinding raw ores by a primary ball grinder and grinding the raw ores until the content of a -0.074-micron grain level in primary grading overflowing is 55%; feeding to a cyclone to carry out primary rough-fine grading work to obtain deposited sand of the cyclone of the primary rough-fine grading work; and feeding into primary reselection; (b) feeding the overflowing of the primary rough-fine grading work to secondary rough-fine grading work; and feeding deposited sand of the secondary rough-fine grading work to secondary reselection; and (c) feeding an overflowing product of the secondary rough-fine grading work to magnetic selection work, and feeding concentrate ores of the magnetic selection work to floating selection work, wherein tailings of the magnetic selection work are magnetic selection tailings. The invention provides strengthened rough-fine grading work of a poor hematite ore treatment plant so that the concentrate ore cost is effectively reduced and the iron level of the comprehensive tailings is controlled.

Iron contaminants are removed from hydrocarbon oils, and from produced water or flowback water by-products of oil and gas production, by treatment of such liquids with a composition comprising a two-tail lipid compound. The lipid binds iron to form a lipid / iron phase in the liquid, which is then removed to provide a liquid with a reduced iron level.

A method for arranging and installing the anchor bolts of a marine diesel engine on a test bench, comprising the steps of: 1) installing several general-purpose test iron benches on the test bench; 2) arranging the anchor bolts of the marine diesel engine according to the shafting arrangement and model of the marine diesel engine 3) Seat the marine diesel engine on the test iron bench and correct the level; 4) Install and use pneumatic tools to fasten the anchor bolts of the marine diesel engine; When all the fastening torques sampled and checked all meet the requirements, the arrangement and installation of the anchor bolts of the marine diesel engine on the test bench is completed. The invention solves the problem of complex and difficult arrangement of anchor bolts of marine diesel engines, improves labor production efficiency, reduces labor intensity of operation, improves the safety of operators, and at the same time ensures the reliability of anchor bolt connection of diesel engines, and is applicable to It is suitable for various types of marine low-speed diesel engines, and meets the requirements for the arrangement and installation of anchor bolts for the diesel engine platform test run.

The invention discloses a method for making a pocket, a mouth of which is in a random shape. The method comprises the following steps: (1) placing first pocket cloth (1) on a pocket-demanding part of a garment piece (2) and ensuring that the front face of the first pocket cloth (1) is upward; (2) drawing a shape of the pocket mouth on the front face of the first pocket cloth (1); (3) stitching along a contour line (3) of the drawn shape of the pocket mouth and connecting the first pocket cloth (1) with the garment piece (2); (4) cutting and hollowing along the contour line (3) of the drawn shape of the pocket mouth by means of retraction of 0.2-0.6 cm, and cutting a hole when coming across a corner of the contour line (3); (5) turning the first pocket cloth (1) inside through a hollowed part (4); (6) ironing level the hollowed part (4) and the edge thereof; and (7) stitching second pocket cloth (2) with the first pocket cloth (1) already positioned behind the garment piece (2) to compete making the pocket.

The invention discloses a thiazolidone compound, wherein a chemical structure of the thiazolidone compound is shown in a general form (I). The invention also discloses application of the thiazolidone compound in preparation of a medicine used for treating thalassemia. Experiments prove that the thiazolidone compound can be used for effectively stimulating expression of hepcidin in cells under the condition that concentration is 10mu M, can be still used for effectively inducing expression of hepcidin in liver when being exposed for 6 hours, 24 hours and 48 hours respectively at a dosage of 30mg / kg in animal level and can be also used for effectively reducing level of serum iron, so that the thiazolidone compound can take hepcidin as a target, can be used for reducing iron level in serum, is hopeful to be a potential medicine used for treating and alleviating iron disorder-related diseases and has a broad clinical application prospect and a great economic development value.

The invention discloses a method for improving the metallization rate of a metallurgical slag pellet. The method comprises the following steps: (1) mixing a carbonic substance with an adhesive for pelletizing for the first time to obtain a carbonic pellet; (2) mixing the carbonic pellet with a mixture containing metallurgical slag, a reducing agent, the adhesive and an additive for pelletizing for the second time to obtain the metallurgical slag pellet with the carbonic pellet serving as a core; (3) wrapping the metallurgical slag pellet to form a high-temperature-resistant layer on the surface of the metallurgical slag pellet; and (4) roasting the metallurgical slag pellet with the high-temperature-resistant layer to obtain a metalized pellet. According to the method, the metallization rate of the metallurgical slag pellet can be remarkably improved, so that a product with higher iron level and higher recovery rate is obtained favorably in the subsequent treatment process.

The invention provides a method for producing molten iron with high-phosphorus and low-iron refractory iron ore, comprising the following steps: taking high-phosphorus and low-iron refractory iron ore as raw material; taking wood coal as reducing agent; oxidizing roasting; directly reducing; magnetically separating and separating; melting and separating; dephosphorizing molten iron; and obtaining the low-phosphorus molten iron. The method can process the extremely refractory iron ore with high P content, high S content, high SiO2 content and low iron level, has high ore iron recovery rate, completely solves the difficulties of the high-phosphorus and low-iron refractory iron ore such as ore selecting and smelting, removing coke, and eliminating high-energy consumption and high-pollution technical process such as ore selecting, sintering, palletizing, coking, etc. Phosphorus-containing slag can realize resource comprehensive utilization. A great number of experiments and semi-industrial production demonstrate that the technical economic effect of the method is remarkable and effectively solves the current problem of ore resources supply-demand contradiction in China.
