The use of sintered CaO as a refractory material is not uncommon. Refractory material based on lime as the lining of the Bessemer converter was applied for the first time in 1875 in order to carry out desulphuring and dephosphoring of the molten pig iron. Due to interaction of the porous burned CaO with the atmospheric moisture during dead time followed by damage and disintegration of this case...

To elucidate the mechanism by which quercetin enhances the rate of tension development in skinned muscle fibers, effects on calcium release from longitudinal tubule-derived SR (LSR) after phosphate-supported calcium uptake were examined. In all studies, 100 microM quercetin (which inhibits initial calcium uptake velocity 85%) was added at or shortly after the time calcium content reached a maxi...

Dechlorination of hexachlorobenzene (HCB) was achieved by a mixture of commercial CaO and alpha-Fe2O3 (CaO/alpha-Fe2O3) in closed systems at temperatures of 300 degrees C and 350 degrees C, which exhibited a synergic effect compared to CaO or alpha-Fe2O3 alone, and the dechlorination efficiency was dramatically enhanced. When CaO and alpha-Fe2O3 coexisted, HCB was dechlorinated by about 98% aft...

The ability of calcium peroxide (CaO(2)) to immobilize As of contaminated soil was studied using pot and field experiments. In pot experiment, CaO(2) applied at 2.5 and 5 g kg(-1) significantly increased celery shoot weight and decreased shoot As accumulation, which was ascribed to the formation of stable crystalline Fe and Al oxides bound As and the reduction of labile As fractions in the soil...

The sesquiterpenes β-caryophyllene, β-caryophyllene oxide (CAO), α-humulene (HUM), trans-nerolidol (NER), and valencene (VAL) are substantial components of the essential oil from Myrica rubra leaves which has exhibited significant antiproliferative effects in several intestinal cancer cell lines, with CaCo-2 cells being the most sensitive. The present study was designed to evaluate the effects ...

Thirteen adult patients underwent palliative Nd-YAG laser treatment for relief of severe dyspnea due to malignant endotracheal obstruction. Three of the 13 patients had underlying chronic airflow obstruction (CAO) due to diffuse obstructive pulmonary disease. Despite dyspnea, cough, wheezing, stridor and/or hemoptysis, the diagnosis was delayed because of a normal chest roentgenogram in eight p...

The goal of this study was to determine if changes in the epicardial QRS complex after coronary artery occlusion (CAO) can be used to evaluate the efficacy of interventions designed to limit infarct size. Forty-one open-chest dogs with CAO were studied: 15 were controls, 18 received hyaluronidase and eight received propranolol starting 20 minutes after CAO. Epicardial ECGs were recorded at spec...

This experiment was conducted to evaluate the intake, nutrient apparent digestibility and the effect of total collection days (two and four days) on apparent digestibility estimates for lambs fed diets containing sugar cane treated with calcium oxide (CaO). Eight Santa Inês castrated male lambs with a 16.6±1.8 kg body weight were used. The lambs were distributed in two 4×4 Latin squares, with f...
