Angular correlation measurements in the O18(p, p′ γ)O18 reaction
Nuclear Physics, 1965The levels at 3.92, 4.45, 5.09 and 5.25 MeV in O18 have been investigated using p-γ angular correlation measurements in the O18(p,p′γ)O18 reaction. The spin of the level at 4.45 MeV has been established as one. This level was found to decay 64±5% to the 3.63 MeV 0+ level and 36±5% to the 1.98 MeV 2+ level, with an upper limit of 4% placed on the ground

The volcanic rocks of Iceland are anomalous in their oxygen isotope content. Recent tholeiitic and transitional alkali basalts from Iceland range in (δO18 from 1·8 to 5δ7%. Most of the tholeiitic basalts and their phenocrysts are at least 1% lower in δO18 than unaltered basalts from other oceanic islands or oceanic ridges.

O18. Oxidative stress in preeclampsia
Pregnancy Hypertension: An International Journal of Women's Cardiovascular Health, 2015Introduction Preeclampsia (PE) is characterized by hypertension and proteinuria that affects 5–10% of pregnancies. Risk factors of PE cause the release of reactive oxygen species, which lead to increased vascular cell proliferation and hypertrophy, apoptosis, inflammation and extracellular matrix remodeling.

ABSTRACT Seven new 14C age determinations on short‐lived materials yield a sound evidential basis for the chronology of the O18 site on O'ahu Island, Hawai'i, long thought to be an early settlement site. Calibration within a model‐based, Bayesian framework indicates that the site was established in AD 1040–1219, some 260–459 years after the current ...
