Abstract: A powder rotary fluidization device and a method thereof are provided. The powder rotary fluidization device includes a support device, the support device is provided with an installing plate, the installing plate is provided with a power device and a fluidization device, and the power device is in transmission connection with the fluidization device. After a position of the fluidization device on the installing plate is adjusted through the support device, the power device is started to drive the fluidization device to rotate, and meanwhile gases are introduced into the fluidization device to process powder. and therefore the problem of poor processing effect on fine powder with high viscosity is solved through the rotatable fluidization device.

Abstract: A device suitable for forming spherical particle clusters from fine powder is a device through which spherical particle clusters having a controlled particle size and a controlled hardness can be prepared from the fine powder by using a rolling granulation principle without adding any solution or solid binder. In particular, the device includes the following components: a) a preforming device for preforming particle clusters formed from fine powder, so that the particle clusters have a certain strength and shape while conveying the particle clusters to a next step at a certain speed; b) a spheroidizing device for further strengthening the particle clusters formed by a) the preforming device, so that the particle clusters have a higher sphericity and hardness; and c) a grading device for sieving the particle clusters spheroidized by b) the spheroidizing device to obtain particle clusters of different particle size ranges.

Abstract: A high-efficiency and high-precision combined machining apparatus for a diamond wafer sheet and a combined high-efficiency and high-precision method for machining a diamond wafer sheet are disclosed. The apparatus can comprise a machining motion platform component installed on a base, a laser machining component, a grinding component, a polishing component and a detection component installed on a support frame. In operation, a high-energy laser beam of the laser machining component can focus on the surface of the diamond wafer sheet to be machined and perform a straight reciprocating irradiation on the diamond wafer sheet, thereby realizing the planarization machining of the diamond wafer sheet. Further, the grinding component and the polishing component realize further high-precision grinding planarization and finishing polishing machining under the action of the laser machining component.

Abstract: Disclosed and claimed are compositions and methods for therapy and/or prevention of restenosis and/or atherosclerosis. The compositions can include an agent for decreasing viral load of cytomegalovirus, such as an immunological composition or vaccine against cytomegalovirus (CMV) containing at least one epitope of interest of CMV and/or an expression system which expresses at least one epitope of interest of CMV. Such compositions can include at least one epitope of p53. Alternatively, the compositions can include at least one epitope of p53 and/or an expression system which expresses the epitope. The methods can include administering the compositions to a patient in need of such therapy and/or prevention.
