Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. [1] The denser components of the mixture migrate away from the axis of the centrifuge, while the less dense components of the mixture migrate ...
A centrifuge is a device for separating particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. In a solution, particles whose density is higher than that of the solvent sink (sediment), and particles that are lighter than it float to the top. The greater the difference in density, the faster ...

The classification results are also significantly different, as Centrifuge can give multiple assignments per read while Kraken 2 gives each read one taxonomic assignment. While both rely on exact k-mer matching, Kraken 2 analyzes all k-mers of the same length in a read (35bp k-mers by default) while Centrifuge starts with a 16bp at …

Any attempt systematically to classify the different centrifuges, including gas centrifuges, arrives at the following main definition of the physical forces occurring in the centrifuge: gas separation, demulsification, sedimentation and filtration (Figure 1).Demulsification is the separation of a liquid mixture into two liquid phases with different densities, which also …
Second, air is present in the annulus, creating free gas-liquid surface that forms an upper boundary; thereby, air can be easily entrained in the turbulent liquids. Thirdly comes the geometrical difference: the inner rotor in ACC does not extend all the way to the bottom of the housing, and the vanes at the bottom also have considerable effects ...

A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a potentially strong force perpendicular to the axis of spin (outward). The centrifuge works using the sedimentation principle, where the centripetal acceleration causes denser substances and particles to move outward in the ...
En 1689, le physicien Denis Papin a inventé la pompe centrifuge. Aujourd'hui, les pompes centrifuges sont les pompes les plus utilisées dans le monde. La pompe centrifuge est conçue selon un principe simple : le liquide passe par l'œil de la roue et est poussé vers l'extérieur par une force centrifuge vers la périphérie de la roue.
Integrated (Newtonian) classification efficiency η N is defined as follows: (1) η N = x f-x b x b-x f x f 1-x f x a-x b. For an air cyclone centrifugal classifier and regardless of the material properties and number of meshes, x a = 1 [32]. Accordingly, Eq. (2) can be rewritten in the form below: (2) η N = x f-x b x f 1-x b × 100 %
