Abstract: A grafted polypropylene resin is prepared by a grafting reaction of a polar monomer capable of absorbing microwave so as to raise its temperature in a microwave field to more than 200° C. and a solid polypropylene resin using microwave irradiation without adding an initiator. The polar grafted polypropylene resin that does not contain initiator residues and does not have a significant reduction in molecular mass compared with a resin before grafting is obtained.

Abstract: A continuous operation method is employed for the microwave high-temperature pyrolysis of a solid material containing an organic matter. The method includes the steps of mixing a solid material containing an organic matter with a liquid organic medium; transferring the obtained mixture to a microwave field; and in the microwave field, continuously contacting the mixture with a strong wave absorption material in an inert atmosphere or in vacuum. The strong wave absorption material continuously generates a high temperature under a microwave such that the solid material containing an organic matter and the liquid organic medium are continuously pyrolyzed to implement a continuous operation.

Abstract: A rotary push-pull rope retractor includes a top cover, a follower, a seat, a control member and a base. The seat is fixedly installed on the base. An upper surface of the seat is provided with an elastic member and a pawl connected with the elastic member. The follower includes a ratchet and a rope bin. The pawl is located on one side of the ratchet and engaged with the ratchet. The control member is slidably arranged on the upper surface of the seat, and the control member can push the pawl to move away from the ratchet and compress the elastic member to separate the pawl from the ratchet, so as to switch the meshing mode or the free mode of the rotary push-pull rope retractor. The top cover is arranged above the seat, and the top cover and the follower are connected in linkage.

Abstract: Provided herein is a coffee machine, comprising a main body (1) that comprises a housing (101) of the main body, a pot liner (103) disposed within the housing (101), a heating mechanism for heating liquid in the pot liner (103), and a container (106) disposed above the pot liner (103) and being in communication with the inner space of the pot liner (103); a capsule base (2) detachably connected on the bottom of the main body (1); and a power-controller holder (3) detachably connected to the outside of the housing (101), for supporting, powering and controlling the main body (1). The coffee machine as described herein has a modularized structure for ease of using the coffee machine in various settings and ease of disassembly, maintenance and cleaning of the coffee machine.

Abstract: A coffee machine includes a pot liner and a heating mechanism for heating the pot liner. The pot liner has a water inlet and a water outlet. An automatic drain mechanism is provided at the water outlet of the pot liner for opening or blocking the water outlet according to the ambient temperature at the water outlet. The automatic drain mechanism can be used to control outflow of the heated water from the pot liner according to the ambient temperature, so that the structure for exhausting water is simplified and the size of the coffee machine is reduced. Moreover, the fluid flowing out under the pressure generated due to steam will facilitate to brew ground coffee, thereby enhancing the quality of coffee.

Abstract: The invention concerns a method for the hyperpolarisation of 13C nuclear spin in a diamond, comprising an optical pumping step, in which colour centre electron spins in the diamond are optically pumped. The method further comprises a transfer step in which the polarisation of a long-lived state of the colour centre electron spins is transferred to 13C nuclear spins in the diamond via a long-range interaction.

Abstract: A method for characterizing the risk associated with atherosclerosis is disclosed. The method uses one or more images of cross-sections of the artery or other vessel of interest to identify and locate components of the atherosclerotic deposit, including any hemorrhage, necrotic core, and calcification, and to determine the status and composition of the fibrous cap. In one embodiment, high resolution MRI images are utilized, although other imaging modalities may alternatively be used. A simple scoring system is applied that accounts for the presence of these components and more heavily weights the presence of these components in the juxtaluminal portion of the deposit. The status of the fibrous cap (intact or ruptured) and the composition of the fibrous cap (collagen or mixed tissue) are also incorporated into a final atherosclerosis risk score.
