In list-method directed forgetting, participants are cued to intentionally forget a previously studied list (List 1) before encoding a subsequently presented list (List 2). Compared with remember-cued participants, forget-cued participants typically show impaired recall of List 1 and improved recall of List 2, referred to as List 1 forgetting and List 2 enhancement. In 3 experiments, we examine...

Corrosion of 1020 carbon steel coupons in natural seawater over a 1-year period was more aggressive under strictly anaerobic stagnant conditions than under aerobic stagnant conditions as measured by weight loss and instantaneous corrosion rate (polarization resistance). Under oxygenated conditions, a two-tiered oxide layer of lepidocrocite/goethite formed. The inner layer was extremely tenaciou...

CM chondrites are aqueously altered rocks that contain ~9 wt.% H2O (indigenous water) [1] bound in phyllosilicates [2-4]; also present in the matrix are serpentinetochilinite intergrowths (PCP), pentlandite, and Ni-bearing pyrrhotite. The extent of alteration varies from meteorite to meteorite. Some CM chondrites contain well-delineated metallic-Fe-Ni-bearing, olivineand pyroxene-rich chondrule...

In this study, Fe(II) complexes of phenyldithiocarbamate, dimethyldithiocarbamate and imidazolyldithiocarbamate were used as single-source precursors to prepare iron sulphide nanoparticles by thermolysis in oleic acid/octadecylamine (ODA) at 180 °C. The nanoparticles were dispersed into hydroxyethyl cellulose (HEC) to prepare iron sulphide/HEC nanocomposites. Ultraviolet-Visible (UV-Vis), Photo...

OBJECTIVE To analyze time and geographical trends of breast cancer mortality. METHODS Annual mortality rates per 100,000 female inhabitants aged 20 to 59 years for the Baixada Santista metropolitan area, the city and state of São Paulo and Brazil, from 1980 to 1999, were standardized by age groups and analyzed. The analyses included regression models to estimate and compare time trends of eac...
