Availability of calcium from skim milk, calcium sulfate and calcium carbonate for bone mineralization in pigs.
Dairy products provide abundant, accessible calcium for humans, while some calcium sulfate-rich mineral waters could provide appreciable amounts of calcium. But there is little evidence that this calcium is as available as milk calcium for making bone. The availability of calcium was studied by monitoring bone parameters in 2-month-old pigs fed restricted amounts of calcium (70% RDA) for 2.5 mo...
متن کاملMicrowave-assisted synthesis of SiO2 nanoparticles and its application on the flame retardancy of poly styrene and poly carbonate nanocomposites
Various morphologies of silica nanoparticles were synthesized by a microwave-assisted Pechini method. Silica nanostructures were synthesized via a fast reaction between tetra ethyl ortho silicate and ammonia at presence citric acid and other effective agents in Pechini procedure. Then for preparation of polymer-matrix nanocomposites, SiO2 nanoparticles were added to poly carbonate (PC) and poly...
متن کاملAn improved flame-photometric method for determining calcium in serum.
Powell (1953) introduced a method for the estimation of serum calcium using the EEL flame photometer, and claimed that it gave results in good agreement with a standard titrimetric procedure. In this laboratory, both these methods were found to give low results when tested against standard sera, prepared by adding known amounts of calcium to serum completely decalcified by treatment with a cati...
متن کاملCyanobacteria as Biocatalysts for Carbonate Mineralization
Microbial carbonate mineralization is widespread in nature and among microorganisms, and of vast ecological and geological importance. However, our understanding of the mechanisms that trigger and control processes such as calcification, i.e., mineralization of CO2 to calcium carbonate (CaCO3), is limited and literature on cyanobacterial calcification is oftentimes bewildering and occasionally ...
متن کاملInfluence of substrate mineralogy on bacterial mineralization of calcium carbonate: implications for stone conservation.
The influence of mineral substrate composition and structure on bacterial calcium carbonate productivity and polymorph selection was studied. Bacterial calcium carbonate precipitation occurred on calcitic (Iceland spar single crystals, marble, and porous limestone) and silicate (glass coverslips, porous sintered glass, and quartz sandstone) substrates following culturing in liquid medium (M-3P)...
