Voorbeelden van strontium

• However, neither e strontium and ethanol individually, nor the association of both were efficient to produce parthenogenetic blastocysts.

• Intense emission was observed for strontium with hydrogen gas, but no emission was observed with hydrogen or strontium alone.

• Only one calf was obtained in the group activated with ionomycin and strontium.

• A live female calf was obtained when ionomycin/strontium were used, but it died 30 days after birth.

• This work is supported by partial strontium isotope data that clarify some key biostratigraphic problems.

• All samples have been analysed for strontium isotope ratios; these fall in the range 0.70645 to 0.70710.

• The previously suggested correlation is not valid even if the strontium isotope system was reset.

• Post-depositional contamination of tooth enamel (diagenesis) is normally not significant in strontium-isotope studies.
