Nickel hydroxy-carbonate precipitation in a pellet reactor
Precipitation in pellet reactors was developed primarily for water softening purposes, and then extended in the Netherlands in a research context to heavy metal recovery from stream concentrations varying from 10 to 10 000ppm. The metals include copper, iron, lead, manganese, nickel and zinc. The …

Small scale manufacturing and scintigraphic detection of pellet formulations
… designed to develop radiolabelling methods for pellets or mini-tablets so that their in vivo behaviour can be assessed using gamma scintigraphy. Eight different pellet formulation profiles were developed using paracetamol and indomethacin as partially and poorly water soluble model drugs …

Lithium pellet injection into high pressure magnetically confined plasmas
The ablation of solid pellets injected into high temperature magnetically confined plasmas is characterized by rapid oscillations in the ablation rate, and the formation of field aligned filaments in the ablatant. High speed imaging of the ablation (> 250, 000 frames/second) during the 2003-2004 …

Theoretical Study on Magnetic Shielding of an Ablating Solid Hydrogen Pellet in a Plasma and Hydrogen Pellet Production and Injection Into the Apex Tokamak
The ablation rate of a solid hydrogen pellet in a plasma is the critical factor in determining the feasibility of pellet refueling of toroidal magnetically confined thermonuclear reactors. Initial experiments at Oak Ridge National Laboratory involving small pellets (diameter of order 200 (mu)m) and …

Development of a seeding pellet system for use in soil conservation forestry
… upon the existence of effecting seeding pellet systems. Systems developed by private companies have not been rigorously reviewed, nor is much of the data available on their success rates, necessitating development of a new system with openly available data on its effectiveness. In the …

Production of uniform micropellets of hydrogen and hydrogen pellet injection on ORMAK
Injecting pellets of solid deutrium-tritium has been previously proposed as a method for refueling fusion reactors based on the magnetic confinement of a plasma. An experimental study was undertaken to determine the interaction of a hydrogen pellet with a high temperature plasma. An apparatus was …

The Development of Hybrid Process Control Systems For Fluidized Bed Pellet Coating Processes
<p>The conventional basic control for pharmaceutical batch processes has several drawbacks. The basic control often uses constant process settings discovered by trial and error. The rigid process operation provides limited process understanding and forgoes the opportunities of process optimization. …
