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 ...

Structure of the O18 antigen from Acinetobacter baumannii
Carbohydrate Research, 1997The polymeric O antigen was obtained from lipopolysaccharide extracted from isolated, defatted cell walls of the reference strain for Acinetobacter baumannii serogroup O18. Monosaccharide analyses and NMR spectra established that the polymer had a regular structure with a repeating unit based on residues of D-galactose (2), N-acetyl-D-galactosamine (1),

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

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.

A study of the reactions O17(He3,α0), O18(He3,α0) and O18(He3,α1)
Nuclear Physics, 1965Abstract The angular distribution of the alpha particles from each of the reactions O 17 ( He 3 , α 0 ) O 16 , O 17 ( He 3 ,α 0 ), O 18 ( He 3 ,α 0 ) and O 18 ( He 3 ,α 1 ) O 17∗ has been measured over an angular range of 0–160° at thirteen values of ...
