The efficiency of pellet injection and the relationship between D/T fuel ratio and plasma parameters were analyzed numerically using the TOTAL (toroidal transport analysis linkage) simulation code, which consists of the equilibrium calculation code and a one-dimensional transport simulation model. The simulation which included scanning the pellet penetration depth and the pellet D/T ratio was p...

in this study, the isothermal reduction of iron oxide pellets, made of iranian chadormalo, gole-gohar, and sangan iron ores, was investigated in the temperature range of 900-1100°c. tabas, pabdana, babnizoo, karmozd, and shahrood domestic coals were used as reductants. parametric studies were performed and the effects of such factors as temperature, average particle size of iron ore and coal fi...

Spontaneous migration of airgun pellet in the brain CT scans of an 18-year-old girl shot in the right eye by a 0-177 airgun pellet fired from close range. Top left: The pellet passed through the orbital roof, entered the intracranial compartment via the cribriform plate and lodged in the left cerebral hemisphere adjacent to the anterior limb of the internal capsule (arrow, top right). Bottom le...

The Compact Ignition Tokamak (CIT) will use an advanced, high-velocity pellet injection system to achieve and maintain ignited plasmas. Two pellet injectors are provided: a moderate-velocity (1 to 1 S-km/s), single-stage pneumatic injector with high reliability and a high-velocity (4to 5-km/s), two-stage pellet injector that uses frozen hydrogenic pellets encased in sabots. Both pellet injector...

BACKGROUND Exposure to a warm environment has been reported to be effective for recovery from mental fatigue. However, there have been no reports examining the effects of a pellet stove on recovery from mental fatigue. The purpose of this study was to examine the effects of a pellet stove on recovery from mental fatigue. MATERIAL/METHODS In this placebo-controlled, crossover experiment, 16 he...

The present experiments investigated the role of signals for pellet delivery in the development of polydipsia on random time schedules. In Experiment 1, when an explicit signal or auditory stimulation from pellet dispenser operation was available to the rats, polydipsia developed in all ofthe animals. In Experiment 2, animals receiving signaled pellet deliveries developed polydipsia more quickl...

objective(s) the aim of this study was to investigate the possibility of production of ibuprofen pellets with high amount of rate retarding polymer by aid of peg400 as plasticizer. materials and methods polyethylene glycol (peg400) in concentrations of 1, 3 or 5% w/w with respect to eudragit rl was used in production of pellets containing 60% ibuprofen and 40% excipient (2% polyvinylpyrrolidone...

Contact between the outer surface of a fuel pellet and the inner surface of the fuel rod cladding can result in several kinds of undesirable behavior. As the pellet swells outward and the cladding creeps down, large stresses are generated in both the pellet and the cladding. This contact may exacerbate chemical degradation of the cladding and the stress may enable rapid propagation of cracks. B...

Given the vital role of early adopters during the early stage of wood-pellet heating development, this study aims to explore the factors that explain the overall satisfaction among the early adopters of this type of heating as well as the problems experienced with wood-pellet heating in Norway. Ordinal regression was used to analyze empirical data which was collected from a mail survey in autum...

The primary objective of this study was to observe the effect of pellet length on utility and combustion temperature. Pellets with various lengths were combusted in a pellet stove. Pellet length was found to have a significant effect on the combustion temperature and stability. Increasing the length of pellets from 5.8mm to 13.1mm decreased the average burning temperature by 31% and flue gas te...
