the authors present new data on Mytilus edulis shells REY content and fractionation as a potential proxy for REY content in seawater. The potential impact of pH and temperature on such REY signal in the mussel shells is investigated, as well as the potential process of shells REY incorporation. Part of the paper also deals with shell preparation and analytical procedures for analyses of such lo...

The origin of deep-sea sediments in the western North Pacific Ocean, which are significantly enriched rare-earth elements and yttrium (REY), its paleoceanographic implications have been poorly constrained. Here, we investigated stratigraphic variations chemical compositions textures ferromanganese (Fe–Mn) micronodules separated from sediments. characteristics an extremely REY-rich mud layer var...

This study aimed to assess the levels of rare earth elements and yttrium (REY) vanadium (V) in soils cultivated with citrus, oil palm black pepper eastern Amazon . The potential risk contamination was estimated using enrichment (EF) bioaccumulation (BAF) factors. results showed that pH, K, P significantly affected REY concentrations. europium most significant among studied elements. contents V ...

BACKGROUND Large variability in tests and differences in scoring systems used to study central coherence in eating disorders may lead to different interpretations, inconsistent findings and between study discrepancies. This study aimed to address inconsistencies by collating data from several studies from the same research group that used the Rey Osterrieth Complex Figure Test (Rey Figure) in o...

the general purpose of this research was survey and recognizes the positive and negative effects of industrial site of eshtehard rural development in eshtehard region statistical populations were two groups’ namely rural people and master of industrial area. the size of the sample was 150 villagers and 70 masters of industrial units. (using stratified proportionate random sampeling technique an...
