AIM This was to assess the prevalence of Early Childhood Caries (ECC) among preschool children attending nursery schools and to compare the results with those of a previous survey where the investigators used the term and diagnosis for Baby Bottle Tooth Decay (BBTD) syndrome. METHODS A cross-sectional survey of 1006 children aged 1-6 years was carried out. WHO recommendations for oral health ...

We have performed U-Th isotope analyses on pure aragonite samples from the upper sections of Leg 166 cores to assign each aragonite-rich sediment package to the correct sea-level highstand. The uppermost sediment package from each of the four sites investigated (Sites 1003, 1005, 1006, and 1007) yielded a Holocene U-Th age. Sediment packages from deeper in the cores have suffered diagenesis. Th...

The present study investigates the effects of process parameters on cold forming an automotive component in AISI 1006 low carbon steel. material formability was characterised up to 250°C. flow behaviour and related thermal distributions during geometrical transformations were analyzed. Coining operations investigated by using a coupled 3D Thermo-mechanical FEM with different die geometries fric...

BACKGROUND The aim of this study was to determine the occurrence of extra-enteric findings in a large cohort of patients undergoing magnetic resonance enterography (MR-E) and to classify the clinical significance of these findings. MATERIALS AND METHODS We retrospectively analyzed 1154 MR-E performed in 1006 patients referred to our radiological department between 1999-2005. The reasons for r...

The north east shell of SN 1006 is the most probable acceleration site of high energy electrons (up to ∼ 100 TeV) with the Fermi acceleration mechanism at the shock front. We resolved non-thermal filaments from thermal emission in the shell with the excellent spatial resolution of Chandra. The thermal component is extended widely over about ∼ 100 arcsec (about 1 pc at 1.8 kpc distance) in width...
