Abstract Horizontal vibrating centrifuge and vertical scraper are the main equipment for dehydration of final coal in preparation plant. They widely used. There many misunderstandings actual selection centrifuges, which brings unnecessary problems to later use. In view how reasonably select two kinds improve use effect structural composition, working principle maintenance cost centrifuges compa...

Abstract This study compared a field versus reference laboratory technique for extracting (syringe vs. centrifuge) and analyzing sweat [Na(+)] and [K(+)] (compact Horiba B-722 and B-731, HORIBA vs. ion chromatography, HPLC) collected with regional absorbent patches during exercise in a hot-humid environment. Sweat samples were collected from seven anatomical sites on 30 athletes during 1-h cycl...

The address calculation for distributed data access plays a major role for the performance of ne-grained data-parallel applications. This paper reports about the hardware centrifuge of the Cray T3E which enables the shift of the address calculation from software into hardware. This shift minimizes address calculation overhead reducing communication cost of dynamic communication patterns. The ce...

A method for driving rotation and a countercurrent flow in a fully ionized plasma centrifuge is described. The rotation is produced by radiofrequency waves near the cyclotron resonance. The wave energy is transferred into potential energy in a manner similar to the α channeling effect. The countercurrent flow may also be driven by radiofrequency waves. By driving both the rotation and the flow ...

This report traces the history of India’s centrifuge enrichment program and assesses its current and projected enrichment capacity based on publicly available procurement data and other publicly available information, which were analyzed using specialized software. Our conclusion is that India is currently operating between 2,000 and 3,000 centrifuges at the Rare Materials Project (RMP), India’...

Humans experience physiological deconditioning during space missions, primarily attributable to weightlessness. Some of these adverse consequences include bone loss, muscle atrophy, sensory-motor deconditioning, and cardiovascular alteration, which may lead to orthostatic intolerance when astronauts return to Earth. Artificial gravity could provide a comprehensive countermeasure capable of chal...
