From theCambridge English Corpus The previously suggested correlation is not valid even if thestrontiumisotope system was reset.

From theCambridge English Corpus The presence of diageneticstrontiumin an enamel sample could mask evidence for migration. From theCambridge English Corpus The ability of embryos activated instrontiumto undergo blastocyst development, establish pregnancy and generate live newborn was evaluated. From theCambridge English Corpus Strontium-isotope studies have focused on tooth enamel rather than bone. From theCambridge English Corpus It should also be noted thatstrontium-isotope ratios in rock commonly vary from the ratios measured for fauna and flora. From theCambridge English Corpus When artificial stimulation withstrontiumwas used, the fertilization of oocytes with heated or ethanol-treated spermatozoa was completely rescued. From theCambridge English Corpus Virtually allstrontiumin vertebrate organisms is found in the skeleton. From theCambridge English Corpus These examples are from corpora and from sources on the web.
