ABSTRACT The main aim of this paper is to present the methodology and the experimental set-up used to determinate the causes of the gearbox crack of a mill used for powder slaked lime manufacturing. There are presented the equipment used, the methodology of equipment calibration and the realised measurements. At the end there are mentioned the main causes that can develop the gearbox frame coll...

Mineralocorticoid receptor antagonists protect against ischemic cerebrovascular disease; this appears to be caused by changes in cerebral vessel structure that would promote blood flow. Therefore, we hypothesized that mineralocorticoid receptor activation with deoxycorticosterone acetate would cause deleterious remodeling of the cerebral vasculature and exacerbate the damage caused by cerebral ...

Based on natural principles, we developed a novel toothpaste, containing morphogenetically active amorphous calcium polyphosphate (polyP) microparticles which are enriched with retinyl acetate (“a-polyP/RA-MP”). The spherical microparticles (average size, 550 ± 120 nm), prepared by co-precipitating soluble Na-polyP with calcium chloride and supplemented with retinyl acetate, were incorporated i...

Abstract Background The plants Cynodon dactylon ( C. ), Emblica officinalis E. Kalanchoe pinnata K. and Bambusa nutans B. ) have been reported to possess diuretic antiurolithiatic potential against ethylene glycol ammonium chloride along with in vitro calcium oxalate (CaOx) crystal growth inhibition property. Our previous research publications a rich presence of antioxidative phytocompounds lik...

The phorbol ester tumor promoter phorbol-12-myristate-13-acetate (PMA) induced mouse resident peritoneal macrophage spreading in an in vitro system in a time- and dose-dependent manner; this process was modified by agents which alter intracellular calcium metabolism. After a 35-min incubation with PMA, 50% of the macrophages were spread (as classified by at least a 2-fold increase in cell surfa...

Microbial-induced CaCO3 precipitation (MICP) is an innovative and rapidly developing technology for sand solidification. The idea this research project was built based on the concept of sustainable development environmental protection. specific material used solidification soluble calcium ions generated by reaction limestone waste, a kind calcium-rich industrial waste from quarry, acetic acid. ...

In the present study we used thapsigargin (TG), an inhibitor of microsomal calcium ATPase, to evaluate the roles of free cytoplasmic calcium and intracellular stored calcium in secretagogue-stimulated enzyme secretion from rat pancreatic acini. Using microspectrofluorimetry of fura-2-loaded pancreatic acini, we found that TG caused a sustained increase in free cytoplasmic calcium by mobilizing ...
