this study investigated the relationship between language learning aptitude (lla) and the use of language learning strategies (llss) among a cohort of iranian efl students at urmia university, iran. the adapted versions of the modern language aptitude test (mlat; carrol & sapon, 1983) and oxford’s (1990) strategy inventory for language learning (sill) were distributed among the participants...

Low oxygen conditions in the modern Baltic Sea are exacerbated by human activities; however, anoxic also prevailed naturally over Holocene. Few studies have characterized specific paleoredox (manganous, ferruginous, euxinic) and their frequency southern sub-basins during these ancient events. Here, we apply a suite of isotope systems (Fe, Mo, S) associated elemental proxies (e.g., Fe speciation...

Previous studies have shown that children's blood lead concentrations tend to increase during hot summer months. In this issue, Lih-Ming Yiin and colleagues from the Environmental and Occupational Health Sciences Institute at Rutgers University and the Robert Wood Johnson Medical School in Piscataway, New Jersey, explore whether some of this elevation can be explained by seasonal increases in t...

Mineralogical and oxygen isotopic analyses of samples from Deep Sea Drilling Project Sites 477, 481, and 477 in the Guaymas Basin indicate the existence of two distinct hydrothermal systems. In the first, at Sites 481 and 478, hot dolerite sills intruded into highly porous hemipelagic siliceous mudstones that were moderately rich in organic matter, thermally altered the adjacent sediments, and ...
