The present disclosure is directed to a medical port drainage assembly that includes a port component and a replaceable catheter. The port component includes a tube having a proximal end, a distal end, and tube walls defining a catheter access lumen. A head component is located on a proximal end of the tube and an assembly retention element is located on a distal end of the tube. The head component is deployed outside the patient's body and defines an opening to the catheter access lumen. The assembly retention element is deployed within a lumen of the patient's body. The port component includes a valve assembly which may be a single valve (e.g., a duckbill valve) or a system of valves. The port component also includes a connector for coupling and decoupling the replaceable catheter to the port component.

A method for preparing an object to be tested, having a given relative permittivity, intended to be illuminated by an incident electromagnetic wave. The method includes: providing a part including a cavity for housing the object and at least one extension element made from a material having a relative permittivity that is preferably equal to that of the object, the extension element at least partially delimiting the cavity and extending to either side of the cavity in a passage direction of the cavity, over a length at least equal, on either side of the cavity, to one third of the length of the cavity in the passage direction, and placing the object in the cavity, such that the object is in contact with the extension element in the passage direction.

A device for preparing bio-oil, a system for preparing bio-oil and a method for preparing bio-oil using the same are provided. Biomass is supplied to an inclined portion of a reactor, and high-temperature hot sand is supplied to an upper side of the biomass supplied to the inclined portion. Then, a heater heats the inclined portion. Thus, the fast pyrolysis performance of the biomass can be enhanced, thereby increasing the yield of bio-oil. Also, combustion gas produced from the heater is supplied to the interior of the reactor, so that the interior of the reactor can be simply formed under a nonoxidizing atmosphere. Accordingly, the device for preparing bio-oil can be manufactured into a very simple structure.

A preparation method of Bacillus subtilis biological composite material loaded with Fe3O4 magnetic nanoparticles with core-shell structure includes the following steps: 1) preparation of Fe3O4 nanoparticles, 2) preparation of Fe3O4@mSiO2 nanoparticles, 3) preparation of Fe3O4@mSiO2@MANHE nanoparticles; and 4) preparation of Bacillus subtilis@Fe3O4@mSiO2@MANHE composite.

Provided are a detection agent for detecting hydroxy vitamin D, preparation method thereof, and use thereof in 25-hydroxy vitamin D immunological detection.
