background: this study was conducted to assess the effect of thickness and hydration condition on the surface microhardness of endosequence root repair material putty (errm; brasseler usa, savannah, ga), a premixed bioceramic material. materials and methods: polymethyl methacrylate cylindrical molds with an internal diameter of 4 mm and three heights of 2, 4, and 6 mm were fabricated. in group ...

in this research, the effects of oxygen injection during the induration process were studied in order to improve the quality specifications and increase the rate of production of the iron oxide pellets. several experiments were carried out in palletizing pilot plant in different conditions of oxygen injection. the results suggested that if only the extra oxygen was injected into the furnace in ...

Abstract Fecal-pellet surveys provide density estimates of pellet groups, which offer a quick and reliable index population densities for white-tailed deer Odocoileus virginianus other wildlife species. Comparisons differing fecal-pellet survey methodologies have previously shown that they vary in the precision. However, researchers made these comparisons outside United States regions with lowe...

Prolonged, continuous absorption of a steroid hormone can be readily accomplished by implantation of the hormone in the form of a compressed pellet or tablet. This study was undertaken in order to determine what plasma levels of progestin result when progesterone is absorbed continuously over long periods. PROCEDURE Pure progesterone, without excipient, was compressed into cylindrical pellets a...

[Purpose] Post-stroke motor recovery consists of both true recovery and compensatory movements. Although compensatory movements are learned more quickly early after stroke, the role of compensatory movement patterns in functional recovery is controversial. We investigated the role of compensatory movement patterns in the long-term functional motor recovery after stroke. [Subjects and Methods] M...

Pellet softening reactors are used in centralized and decentralized drinking water treatment plants for the removal of calcium (hardness) through chemically induced precipitation of calcite. This is accomplished in fluidized pellet reactors, where a strong base is added to the influent to increase the pH and facilitate the process of precipitation on an added seeding material. Here we describe ...

Induration of magnetite pellet involves three important phenomena, namely oxidation, sintering and associate heat transfer; these phenomena are interdependent on determining the final quality of the pellet. In order to study the sintering a novel optical dilatometric method was used. These studies were performed separately for magnetite and completely oxidized magnetite. Further, the sintering ...
