Abstract: A combined platform for testing fireproof materials for cables includes a main frame for providing operating space; an air circulation system including a fresh air supply unit for supplying fresh air into the operating space and an exhaust gas treatment unit for treating the gas in the operating space under set conditions; an open flame system for providing an open flame for testing cables; a water circulation system for supplying water at least to the exhaust gas treatment unit and the operating space; and a control system for collecting at least the temperature and gas concentration in the operating space, and performing process control based on the collected results. The actual working conditions of scenarios such as fire-resistant cable tunnels and fire-resistant cable trenches can be simulated, and multiple tests such as combustion performance test and physical and chemical performance test can be carried out under various working conditions.

Abstract: The field is related to plant breeding and methods of identifying and selecting plants with resistance to southern corn rust. Provided are methods to identify novel genes that encode proteins providing plant resistance to southern corn rust and uses thereof. These disease resistant genes are useful in the production of resistant plants through breeding, transgenic modification, or genome editing.

Abstract: A spur dike type fishway inlet includes an upstream flow block wall, an extra water supply nozzle, and an artificial fish reef. The upstream flow block wall is arranged upstream of a fishway inlet; the starting end of the upstream flow block wall is connected with the upstream side wall of the fishway inlet through a connecting shaft and a hydraulic strut. The extra water supply nozzle is installed in the fishway inlet and is connected to the upstream of a power station through a pipeline to directly supply water to a high water head. The artificial reef is set up within the shielding range of the upstream flow block wall.

Abstract: A cable inspection apparatus includes an image capturing device and a determination device. The image capturing device includes a ring camera frame and a plurality of cameras mounted on the ring camera frame and distributed at intervals on a circumference of the ring camera frame. The cameras simultaneously capture images of a cable to be inspected extending through the ring camera frame from a plurality of different angles. The determination device determines whether or not a portion of the cable is qualified according to the images.

Abstract: Disclosed herein are improved methods for the preparation of oseltamivir, and intermediates useful thereto.

Abstract: The present invention is provided with a lock fixing mechanism with quick assembly and disassembly, with a position lock block coupled to a position lock bar, the position lock block is contacted with the side surface of the position lock bar, by rotating, the position lock block squeezes the position lock bar. Under the action of the pressure, the spring connected to the position lock block deforms that the position lock bar moves towards the deforming direction of the spring, therefore the position lock bar is locked between the position lock block. The entire device doesn't need additional components nor need professional to operate that it has well applicability. The present invention further provides with a booth applied with the lock fixing mechanism with quick assembly and disassembly.
