A system for movement of fluid in a tank comprises: a tank; at least two pumping sets, each pumping set comprising: a pumping line external to the tank and in fluidic communication with the interior of the tank at two separate points of the tank via the two ends of said pumping line, and a pump configured to circulate fluid through the pumping line, wherein each pumping set is configured to collect fluid from the tank at one end of its respective pumping line, circulate the fluid through its respective pumping line and discharge the fluid into said tank through the other end of its respective pumping line, and wherein each pumping set is configured such that the flow of fluid in its respective pumping line is reversible.

The invention relates to an emulsification device for continuously producing emulsions, nano-emulsions, and/or dispersions having a liquid crystalline structure, comprising a) at least one mixing system, b) at least one drive for the stirring element, and c) at least one delivery unit for each component or each component mixture.

Disclosed are the optimal composition and size of DNA/polycation particles for efficient transfection of viral production cells in both adherent and suspension cultures. The size-dependent feature of DNA/polycation particle-mediated transfection for particles between 50 nm and 1000 nm also is disclosed. A new scalable method based on kinetic control of DNA/polycation nanoparticle assembly to prepare shelf-stable particles with defined sizes between 50 nm and 1000 nm also is disclosed. The presently disclosed DNA/polycation particles yield superior and reproducible transfection activity and shelf stability and can be used as an off-the-shelf product.

A method may include determining a first dry mass flow rate of a wet paper material stream based on a first amount of contaminants, a first moisture content, and a first wet mass flow rate of the wet paper material stream, determining a second dry mass flow rate of a wet plastic material stream based on a second amount of contaminants, a second moisture content, and a second wet mass flow rate of the wet plastic material stream, calculating, using the first dry mass flow rate and the second dry mass flow rate, a paper/plastic ratio of a combined stream of the paper material stream and the plastic material stream, and adjusting, a flow rate of paper into the paper material stream and a flow rate of plastic into the plastic material stream such that the calculated paper/plastic ratio of the combined stream equals a target paper/plastic ratio.

A device (1) for mixing, in particular dispersing, includes a housing (2) with at least one inlet (3) and a grinding chamber (13). In addition, the grinding chamber (13) includes a first process region (4) for mixing fed materials, wherein the materials are introducible into the first process region (4) through the at least one inlet (3), and a second process region (5) for diverting the mixture to an outlet (6) as well as a separating device (7) for separating the first process region from the second process region, and a rotor (8) for mixing, in particular dispersing the mixture in the first process region (4), wherein the rotor is drivable by a drive shaft (9). A pump (10) connected upstream is drivable by the drive shaft (9) and materials are feedable by means of the pump (10) into the first process region (4) and the first process region comprises a dispersion volume within the range of 11-501, in a preferred manner of 41-121 and particularly preferred is 61.

A foam production method includes mixing liquid nitrogen with a foaming material to produce foam. A gas is produced in situ from liquid nitrogen. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials, accelerating the extinguishing of the fire.
