Rapid tolerance development to pentobarbital by pentobarbital pellet implantation was evidenced by a decrease in sleeping time after challenge with different doses of sodium pentobarbital ranging from 37.5 to 100 mg/kg i.p. or a fixed dose of 75 mg/kg i.p. of the drug. The sleeping time produced by sodium pentobarbital decreased by 50% after 1 day. After 2 or 3 days of implantation, the sleepin...

Finland currently has tremendous enthusiasm to increase decentralised pellet production alongside of large-scale factories. The aim of research is to promote the development of eco-/cost-efficient Nordic wood-based pellet production by means of multidisciplinary research. Using Finnish conifer stem wood (bark-free Scotch pine sawdust and shavings) as a model raw material, the total functionalit...

application of hyperactivation process in palletizing iron ore, in order to decrease bentoniteconsumption has been investigated. different amounts of bentonite and sodium hydroxide, as activating agents,were added to iron ore and the quality of formed pellets were determined. the results show that addition of 0.01pct. naoh improves the pellet quality significantly while the bentonite content re...

Size measurement of iron ore pellets in industry is usually performed by manual sampling and sieving techniques. The manual sampling is performed infrequently and is inconsistent, invasive and time-consuming. Iron ore pellet’s sizes are critical to the efficiency of the blast furnace process in the production of steel. Overly coarse pellets affect the blast furnace process negatively, however t...

Consistent with human gambling behaviour but contrary to optimal foraging theory, pigeons showed maladaptive choice behaviour in experiment 1 by choosing an alternative that provided on average two food pellets over an alternative that provided a certain three food pellets. On 20 per cent of the trials, choice of the two-pellet alternative resulted in a stimulus that always predicted ten food p...

Missing pellet surface (MPS) defects are local geometric defects in nuclear fuel pellets that result from pellet mishandling or manufacturing. The presence of MPS defects can cause clad stress concentrations that are substantial enough to produce through-wall cladding failure for certain combinations of fuel burnup, and reactor power level or power change. Consequently, the impact of potential ...

The association of radiolabelled taurocholic acid with the solid fraction of a faecal fermentation mixture was measured. A human faecal inoculum was incubated with [24-14C]taurocholic acid and several non-starch polysaccharide sources (pectin, wheat bran, ispaghula (Plantago ovata) husk and seed), glucose or a substrate-free control. Portions of fermentation mixture were taken at 0, 3, 6, 21 an...

There exists in the literature indication that some mitochondrial enzymes, particularly succinoxidase and cytochrome oxidase, are part of the mitochondrial structure and thus are insoluble when the mitochondria are disrupted. I t has further been supposed in particular by Cleland and Slater (1) that this insoluble fraction consists of mitochondrial membranes. However, no direct test of the memb...

Snowshoe hare (Lepus americanus) pellet surveys are an efficient tool for monitoring population trends, but there is no standard methodology used to conduct surveys. To assist researchers in developing protocols, we evaluated pellet-decay rates and aging in 3 snowshoe hare habitat types in Alaska during the peak and decline of the hare population from 1999–2002. We found significant differences...

Tokamak discharges are sometimes terminated by disruptions that may cause large mechanical and thermal loads on the vessel. To mitigate disruption-induced problems it has been proposed that “killer” pellets could be injected into the plasma in order to safely terminate the discharge. Killer pellets enhance radiative energy loss and thereby lead to rapid cooling and shutdown of the discharge. Bu...
