The present disclosure relates to an all-trans retinoic acid liposome formulation and a preparation method thereof. The all-trans retinoic acid liposome formulation includes all-trans retinoic acid and a liposome vector. The disclosure adopts an active drug loading method, including a calcium acetate gradient method or a sodium acetate gradient method. The prepared all-trans retinoic acid formulation has high drug loading and high stability in vivo, thereby increasing the blood concentration and prolonging the half-life of the all-trans retinoic acid.

A conductive silver aluminum paste includes the following components by weight percentage: 80.0%-90.0% of silver powder; 0.3%-2.5% of aluminum powder; 0.0%-1.5% of silicon powder; 1.0%-6.0% of first-type glass powder; 0.5%-4.0% of second-type glass powder; and 7.0%-15.0% of organic vehicle. The first-type glass powder is Pb-Zn-B-O-M glass powder, and the second-type glass powders is Ba-B-O-M glass powder, M is at least one of alkali metal elements; the organic vehicle is a vehicle of organic resin and/or cellulose, and a content of the organic resin and/or the cellulose in the organic vehicle is not higher than 10.0% of a total mass of the organic vehicle. By introducing two different types of glass powder, the contact resistance between the metal grid and the PN junction layer is reduced, thereby obtaining high-performance silver aluminum pastes for N-type Topcon monocrystalline silicon cells and high-efficiency electrode metallization for N-type silicon solar cells.

The present invention relates to a floating hydrophyte planting device, comprising a height-adjustable support, a buoyant rope, a planting net rope, a stabilizing rope and hydrophytes. The height-adjustable support comprises a fixed part and a movable part. The fixed part comprises columns and inclined stayed and fixed steel wires. A sawtooth groove is arranged on one side face of the column in the height direction and has multiple notches at different heights. The movable part comprises a twisting pull rod. The twisting pull rod is provided with a cross locking column vertical to the body of the twisting pull rod. The locking column is limited in the notch. After the twisting pull rod is twisted, the cross locking column may separate from the notch; after the twisting pull rod moves in the vertical direction and is twisted again, the cross locking column is limited in another notch.

A data collection and/or monitoring service residing at a client system collects and sends client system information to a backend system. The client system information is used to update a maintained repository of client system information that is associated with software installed at the client system. The maintained repository is used to determine one or more software update recommendations which are sent to the client system. In response to a trigger event, one or more software updates associated with the update recommendations are automatically downloaded and deployed at the client system. The download and deployment of software updates can be scheduled at the client system.
