The invention relates to a calibration method for clearance between rolls of hot-rolling vertical rolls, which mainly solves the technical problem that strip steel is deficient in quality because verticality and alignment to calibration of vertical rolls are not considered in current methods. The technical scheme is that the calibration method for clearance between rolls of hot-rolling vertical rolls comprises the steps of: 1, finding a rolling center line and marking; 2, additionally arranging two position marks on a transverse slipway of a hot-rolling vertical roll device, and marking the distance from the marks to the rolling center line as |ZB|; 3, hitting apertures on both sides of the vertical rolls to marked positions, wherein a roll block is inside a marking line and aligned with the marking line; 4, measuring the distance from the lower ends on both sides of the vertical rolls to the rolling center line, and marking the measuring point as a point A, the radius of the rolls as R / 2 and the distances from A to a vertical roll operating side and from A to a transmission side as |OA| and |DA|; 5, comparing the measured value |OA|+R / 2 on the operating side with |ZB|, wherein if the difference is in a precision range, the verticality is good, and if the difference is not in the precision range, the clearance between rolls on the operating side is adjusted so that the difference is in the precision control range; 6, adjusting the clearance between rolls on the transmission side by the adjusting method in the step 5; and 7, measuring the total aperture of the vertical rolls, inputting the measured values and calibrating the clearance between rolls of vertical rolls after adjusting the verticality and alignment.

The invention discloses a frozen stock solution of neural stem cells and an application method of the frozen stock solution. The frozen stock solution contains B-27 Supplement without retinoic acid, L-Glutamine, EGF, FGF and vitamin E in Neurobasal-A medium. The frozen stock solution is low in cost; the problem of low thawing rate after existing neural stem cells are frozen is critically solved; and the frozen thawing rate of the neural stem cells is improved.

A method, system and program product for managing energy diversion investigations. An energy diversion case is identified and case information is entered into an energy diversion investigation application. The data entered into the application is automatically accumulated and stored in an energy diversion investigations database. An energy diversion case file is generated and updated by an investigator assigned to the energy diversion case. The energy diversion case file can include case information, condition found, people involved in the energy diversion case, cost and recovery information, legal action taken and account information regarding the premises for which the investigation is being conducted. A revenue protection component determines a cost and a recovery amount associated with the energy diversion case. A report component generates predefined or custom reports for management and analysis.

The invention provides supermolecular hydrogel containing chitosan and gelatin as well as a preparation method and an application of the supermolecular hydrogel and belongs to the field of biomaterials. The supermolecular hydrogel contains a part formed by combining chitosan modified with a beta-cyclodextrin carboxylated derivative and gelatin under the host-guest interaction; chitosan is graftedwith the beta-cyclodextrin carboxylated derivative through an amide group. The preparation method comprises the steps as follows: the chitosan is grafted with the activated beta-cyclodextrin carboxylated derivative through the amide group, then, the gelatin is added, so that the grafted beta-cyclodextrin carboxylated derivative and an aromatic group of the gelatin are in host-guest interaction, and the supermolecular hydrogel containing the chitosan and the gelatin is obtained. The supermolecular hydrogel containing the chitosan and the gelatin has shear thinning and self-healing characteristics and can be used as an injectable cell or drug carrier. The beta-cyclodextrin group in hydrogel and the aromatic group in the gelatin can be used in cell carriers and tissue engineering materials through the host-guest interaction.
