Earth's core is composed primarily of iron (Fe) with about 10% by weight of lighter elements. The lighter elements are progressively enriched in the liquid outer core as the core cools and the inner core crystallizes. Thermodynamic modeling of Fe-O-S liquids shows that immiscible liquids can exist at outer-core pressures (136 to 330 gigapascals) at temperatures below 5200 kelvin and lead to lay...

BACKGROUND Workers on dredgers and lighters on rivers are exposed to the inhalation of aerosols and dusts. OBJECTIVE The aim of this study was to investigate effects of river silt aerosol and dust exposure on the respiratory health of dredging employees. METHODS Six examinations were performed over a period of 2 years at 4-monthly intervals in 54 seamen with higher silt aerosol exposure and...

Maternal cigarette consumption during pregnancy, and infant birth weight were assessed in 427 consecutive births at BMH Rinteln. Smokers comprised 46.1% of the mothers. Babies born to mothers who smoked were significantly lighter than those born to non-smoking mothers, regardless of birth order. Smoking mothers were disproportionately represented in the low birth weight group. (19 out of 24) Th...

The study of discordant monozygotic twins may identify important developmental risk factors for adult psychiatric disorder. Differential experience in utero is one candidate environmental risk factor that may distinguish monozygotic twins. In this report, we examine whether intra-pair differences in birth weight predicts discordance for adult psychiatric disorders in 527 female monozygotic twin...

The aim of the study was to estimate the association between maternal perception of their child's health status and (mis)classification of their child's actual weight with future weight change. We present cross-sectional and longitudinal analyses from the Peruvian younger cohort of the Young Lives Study. For cross-sectional analysis, the exposure was maternal perception of child health status (...
