Abstract: A method of an intestinal protective ostomy with the use of a degradable intestinal diversion device and an intubation includes steps of: preparing the degradable intestinal complete diversion device; after cutting off the terminal ileum intestine, measuring the diameter of the intestine, and then selecting a degradable intestinal diversion device of appropriate specifications according to the diameter of the intestine; when diverting, placing the device in the intestinal cavity, and fixing the ileum on the device with a thread at the convex ring; inserting the stoma drainage tube in the proximal ileum where the device is placed against the direction of intestinal peristalsis; and disintegrating and discharging the device with the contents of the intestine. The invention used with a drainage tube realizes complete intestinal diversion without secondary operations of stoma reintroduction.

Abstract: Disclosed is a pyridazinone compound represented by Formula (I), or a pharmaceutically acceptable salt, prodrug, hydrate, solvate, polymorph, stereoisomer, or isotopic variant thereof. The compound can be used for preparation of medicinal products for treatment and/or prophylaxis of a disease or condition associated with thyroid hormone abnormalities. The compound has higher selectivity to TH?, better pharmacokinetic parameters, desired stability, and higher agonistic activity toward TH?.

Abstract: An automatic righting system includes a discrimination calibration module, a righting module, and a controller. The discrimination calibration module includes a distance sensing unit. The distance sensing unit is located at the front end of the glasses and configured to acquire the distance between the distance sensing unit and a first feature position. The righting module includes a push-up air cushion. The push-up air cushion is mounted at the front end of the glasses. The push-up air cushion is configured to be inflated to push the glasses to move upward. The controller is electrically connected to the distance sensing unit and the push-up air cushion. The controller is configured to control the push-up air cushion to start or stop to right the glasses according to a distance signal of the distance sensing unit.

Abstract: Fast simultaneous feasibility testing (SFT) for management of an electrical power grid is achieved through various innovations. The computation problem relates to evaluation of candidate solutions for external power flows into a power grid, with respect to predetermined constraints and contingencies. A perturbation approach with precomputation is extended to encompass grid states (e.g. time periods) in addition to contingencies. Advantages derive from: fewer factorizations or inversions of large matrices; decoupling of state-dependent and contingency-dependent perturbations, leaving relatively few perturbations jointly dependent on both state and contingency; or making approximations by discarding small jointly dependent terms. Significant computation reductions allow a single workstation to perform SFT for 36 hours of a day-ahead cycle.

Abstract: A mine exploitation method based on stoping, separation and filling control is disclosed herein. The method includes deploying a gangue-less coal mining system; choosing a suitable coal and gangue separation method according to a separation requirement; choosing a suitable filling method according to mine geology, production conditions and rock stratum control requirement; reversely calculating a filling rate according to gangue discharge requirement and control indexes by utilizing theoretical calculation, simulation and experiment; determining a filling process and a separation process according to the filling rate; and feeding back and adjusting the filling process and separation process parameters by monitoring filling and control effect indexes.

Abstract: A degradable intestinal complete diversion device, made of biocompatible degradable materials, includes a circular tube constituting the bridge for the intestinal incisions on both sides to crawl towards each other and anastomosed; the end of the circular tube is connected with a gradually expanding flared opening, and a convex ring for binding the broken end of the intestine is arranged on the circular tube near each flared opening, and the hollow inner cavity of the circular tube is provided with a barrier film for blocking the hollow inner cavity. The invention used with a drainage tube realizes complete intestinal diversion without secondary operations of stoma reintroduction.
