A centrifugal clarifier based on the principles of a hydrocyclone with an impeller was developed for centrifugal clarification of sugarcane juice, for improvement in the quality of jaggery and khandsari. The developed clarifier and an existing standard sedimentation disc centrifuge were tested in regards of effect of operational parameters, namely, settling, boiling, clarificant addition and sa...

Measurements of eye movements have shown that centrifugal movements (i.e. away from the primary position) have a lower maximum velocity and a longer duration than centripetal movements (i.e. toward the primary position) of the same size. In 1988 Pelisson proposed that these kinematic differences might be caused by differences in the neural command signals, oculomotor mechanics or a combination ...

In this paper we propose the study of a centrifugal pump control system driven by a three-phase induction motor, which is supplied by a PhotoVoltaic PV generator. The system includes solar panel, a DC / DC converter equipped with its MPPT control, a voltage inverter to three-phase Pulse Width Modulation PWM and a centrifugal pump driven by a three phase induction motor. In order to control the ...

A breakdown of the standard Watson-type rotational Hamiltonian was suggested for a molecule with H2XYZ structure [Š. Urban and K. M. T. Yamada, J. Mol. Spectrosc. 160, 279–288 (1993)] . This breakdown is due to a near-resonant interaction between the ground state rotational levels and rotational levels in an excited vibrational state. This interaction has been observed in the excited electronic...

We present a method to pump liquids in a centrifugal microfluidic spinning disk from a radial outward position to a radial inward position. Centrifugal forces are applied to compress air in a cavity, this way storing pneumatic energy. The cavity is connected to an outlet channel having a lower hydraulic resistance compared to the inlet channel. The stored pneumatic energy is quickly released by...

The kinetics of the shrinking of polymer gels induced by ultracentrifugal fields is investigated. A theory is proposed to describe the diffusion process of polymer networks under centrifugal fields. The initial shrinking rate is proportional to the ratio of the centrifugal force to the frictional force of networks. The shrinking attains the stationary state as a result of the balance between th...

Energy conversion from PV arrays received a lot of attention, especially in outer-space power system applications. Different methods of peak-power tracking have been proposed to capture the maximum power at different levels of insulation. Many peak-power trackers are implemented with a microprocessor or microcontroller, by using different control strategies. Water pumping from a PV array is a v...

Details of a centrifugal Seitz filter for sterilizing small quantities of fluid were reported some months ago in this journal (Hilson and Elek, 1950). It was then considered that a similar filter, fitted with a gradocol membrane (Elford, 1931) for virus or bacteriophage work where an asbestos pad is not suitable, might be useful. Moreover, a suggestion has been made (Latner and Slack, 1950) tha...
