The role of a mafic component in the petrogenesis of Oceanic Island Basalts (OIBs) is highly debated. As the best studied OIB, Hawaiian lavas provide critical insights into OIB genesis. At a given MgO content, the CaO content in the melt has been used to distinguish between partial melts of peridotite and garnet pyroxenite/eclogite. However, calculations using the BATCH program show that CaO co...

STUDY AIM Total liquid ventilation (TLV) with cooled perfluorocarbons has been demonstrated to induce an ultrafast cardioprotective cooling in rabbits. However, it remains unknown whether this technically challenging strategy would be actually more potent than a conventional external cooling after a prolonged ischemia inducing transmural myocardial infarction. METHODS Anesthetized rabbits wer...

Electrochemical nature of metallurgical reaction arouses more and more attentions, and the most closely related is the electrical conductivity of molten slag. The electrical conductivity of molten slag is not only an important physical property that plays a prominent role in modeling and operating the electric smelting furnace and optimizing the metallurgical process, but also important for und...

The purposes of the present study were to determine (a) whether changes of intracellular [Ca2+] (Cai) can account for the decrease of developed tension observed in rat heart muscle when stimulation rate is increased, and (b) whether the effect of stimulation rate on Cai is altered in conditions in which the rate of repriming of the sarcoplasmic reticulum (SR) is altered, as when perfusate [Ca2+...

In microinjected Myxicola giant axons with elevated [Na]i, Na efflux was sensitive to Cao under some conditions. In Li seawater, sensitivity to Cao was high whereas in Na seawater, sensitivity to Cao was observed only upon elevation of [Ca]o above the normal value. In choline seawater, the sensitivity of Na efflux to Cao was less than that observed in Li seawater whereas Mg seawater failed to s...

A study was carried out to compare the composition and thermal properties of lard (LD) and engkabang fat (EF) - canola oil (CaO) blend interesterified with Candida antartica lipase (C. antartica). A fat blend EF-4 (40% EF in CaO) was prepared and interesterified using C. antartica lipase at 60°C for different time intervals (6 h, 12 h and 24 h) with 200 rpm agitation. The fat blends before and ...

The conversion of thermally pretreated CaO along successive carbonation/calcination cycles has been investigated, as a ected by looping-calcination conditions, by means of Thermogravimetric Analysis (TGA). Sorbent samples have been subjected in-situ to a thermal preheating program based on Constant Rate Thermal Analysis (CRTA) by virtue of which decarbonation is carried out at a low controlled ...

Research has been carried out to determine the optimum conditions for making quicklime (CaO) using Taguchi Method. CaO is burning result of limestone (CaCO_3) in calcination process by releasing CO_2 gas until solids occur. The was calcined at 950^o c. Method a quality improvement technique with selection most influential parameters CaO. are particle size, mass, heating temperature and stirring...
