A microindentor was developed to measure the depth of indentation of the intimal surface of arterial tissue loaded by flat-ended, cylindrical probes. The depth of indentation depended on the initial stretch of the tissue which required a rigid support (plaster of Paris) beneath the adventitial sur...
Paris' plaster is chemically called calcium sulphate hemihydrate. As it is brought to use from Paris, it is called the "plaster of Paris". Prepared by heating gypsum at 373K. Properties: Used as a bandage, proofing material, sealing agent. ...

Alkaline Earth Metals have their s-subshell filled with 2 valence electrons. Understand properties, electronic configuration, analogous behaviour, reactivity, ionization energy of group 2 alkaline earth metals.
The alumina-YSZ composites were prepared through slip casting in plaster of Paris molds (POP) and subsequently sintered at 1600掳C, while the aluminium rods were machined down using a lathe machine to the dimension required. The welding process was carried out under different rotational speeds and...
During the multiple manipulation-casting cycles, the tendons and ligaments on the medial and posterior aspect of the foot and ankle, which are identified as the rate-limiting tissues, usually undergo weekly sequential stretches, with a plaster of Paris cast applied after the stretch to maintain ...
PU foams (obtained from Sydney Heath & Son, UK) with pore sizes of 2.12 mm were invested with plaster of Paris and pyrolyzed in a resistant furnace at 500 ℃ in air for 10 h to completely eradicate the polymer foams and strengthen the plaster mold. AC3A alloy (obtained from Daiki Au...
In this study, a biphasic injectable bone substitute based on beta-dicalcium silicate (Ca(2)SiO(4)) and plaster of Paris (CaSO(4).1/2H(2)O) is presented, and its behavior as cement was studied and compared to that of pure Ca(2)SiO(4) paste. The results demonstrated that the settin...
