Abstract: A production method of low molecular weight ?-glucan includes: inoculating an activated Leuconostoc mesenteroides in a 5 L fermentor at a 10% inoculum. Fermentation broth is placed in the fermentor at an initial pH of 6.8-7.0, temperature of 25° C. to 28° C., stirring speed at 120 r/min, and fermented for 20-40 hours. Dextranase is added after 5-30 hours of fermentation at a dosage of 1/10,000 to 5/10,000 by volume. The molecular weight of ?-glucan is controlled within 10000D by the amount of enzyme added, and the total fermentation process is about 20-40 hours. After the reaction is terminated, the fermentation liquid is concentrated and dried to prepare dietary fiber products with a molecular weight of 500-5000D. The viscosity of the fermentation liquid and concentration of ?-glucan in the fermentation liquid may be reduced to promote the forward reaction, accelerate the sucrose conversion rate and increase the product yield.

Abstract: Disclosed is an immersed cabinet, which includes a cabinet body and a heat sink assembly, wherein the heat sink assembly is in sealed connection with the cabinet body and configured to seal an opening of the cabinet body. The cabinet body accommodates a plurality of devices to be cooled, and cooling liquid is put in the cabinet body and used for immersing the plurality of devices to be cooled. The cooling liquid absorbs heat generated by the plurality of devices to be cooled and then is vaporized. The heat sink assembly exchanges heat with the vaporized cooling liquid, so that the vaporized cooling liquid condenses and flows back to the cabinet body for circulation, and the heat sink assembly dissipates the heat into the atmosphere. Therefore, the heat dissipation structure design of the immersed cabinet is effectively simplified.

Abstract: A native leaflet treatment system and method for treating native heart valve leaflets before heart valve repair or replacement procedure. The treatment system includes a delivery apparatus configured to enter the heart, and a native leaflet treatment device stored in the delivery apparatus in a compressed state. The treatment device includes a clamping structure, which is configured to retain at least a portion of the native leaflets in the deployed state. The treatment device is delivered into the heart using the delivery apparatus, and released near the native heart valve, where the treatment device expands and the clamping structure captures and holds the native leaflet, such that the native leaflets will no longer block blood flow. This improves the dynamics of the blood flow which facilitates subsequent surgical procedures (minimally-invasive surgery or open surgery) for heart valve repair or replacement.

Abstract: A method for recycling waste polyester, in particular to a method for recycling waste polyester by a modified alcoholysis method to recycle waste polyester to prepare dimethyl terephthalate (DMT), is provided and belongs to waste polyester recycling technology field. The waste polyester after dewatering and deoxygenation treatment is used as a raw material, in the step of feeding in melted state the alcoholysis agent is added in the melted waste polyester for preliminary alcoholysis, and the alcoholysis agent is ethylene glycol. On one hand, alcoholysis reaction occurs when the waste polyester raw material are melted, and at the same time, the viscosity of the melted material is reduced. Thus, the melted material remains melted at the alcoholysis temperature and is not easy to solidify again after entering the alcoholysis tank, ensuring that the alcoholysis is carried out under homogeneous conditions.
