Rotating bioreactors such as the High Aspect Ratio Vessel (HARV) provide a low shear and gentle mixing environment, ideal for mammalian cell culture in 3D. The HARV is a cylindrical “disc-shaped” batch culture vessel with no internal moving parts, that rotates about a single axis. Oxygenation is provided by a permeable silicon rubber membrane, allowing the diffusion of gases to and from the med...

The composite pressure vessels are used in varieties of applications such as automobile, aeronautics and chemical engineering. Besides these, they have become very popular in oil and gas transport industries. These pressure vessels are experience very high internal pressures during their operation. The present paper demonstrates a study on cylindrical section of carbon fiber reinforced polymer ...

In this work, the stress distribution along cylindrical composite pressure vessels with different dome geometries is investigated. The contours are generated through an integral method based on shell stresses. Here, influence of each contour at interface dome-cylinder evaluated. At first, formulation for curve generation presented and solved contours. An analytical approach calculation secondar...

Blood vessels are commonly studied in isolation to define their mechanical and biological properties under controlled conditions. While sections of the wall are sometimes tested, vessels are most often attached to needles and examined in their natural cylindrical configuration where combinations of internal pressure and axial force can be applied to mimic in vivo conditions. Attachments to need...

Battery Recycling In article number 2211946, Bartosz A. Grzybowski and co-workers present a one-pot separation of metals from spent lithium-ion batteries. Three liquid layers occupy different segments the rotating cylindrical vessel are intensely stirred to move selected components between layers. only ten minutes, all cobalt manganese migrate feed acceptor layer (red), while lithium nickel rem...

Abstract Free translational oscillations of deformable liquid droplet are considered. It is placed into a vessel filled with another liquid. This has an equilibrium revolution shape. The axis this form perpendicular two parallel solid plates – floor and cover vessel. arbitrary contact angle between the interface substrate can take values in range 0 π. A line velocity linearly proportional to de...

We study experimentally the influence of confinement on the penetration depth of impacting spheres into a granular medium contained in a finite cylindrical vessel. The presence of close lateral walls reduces the penetration depth, and the characteristic distance for these lateral wall effects is found to be of the order of one sphere diameter. The influence of the bottom wall is found to have a...

Delegations of the various satrapies of the Achaemenid Empire are depicted bringing presents to the king on the reliefs of the Apadana in the palace of Persepolis. Among these presents are two which most likely contained gold. One of the members of the Indian delegation carries a pole over his shoulders from which two baskets are hanging filled with two bags each. From the degree of bending of ...
