N-propylsalicylidene based on silica as ion exchanger (IE) was used for the separation by complexation of Mn2+, Co2+, Ni2+, Cu2+, Hg2+, Cr3+, Fe3+, and UO22+ from their parent solutions. IE and its metal complexes are characterized by elemental analysis, electronic and infrared spectra, in addition to thermal analysis in atmospheric pressure. The mode of chelation and the proposed geometric str...

Modern systems that deal with inference in texts need automatized methods to extract meaning representations (MRs) from at scale. Open Information Extraction (IE) is a prominent way of extracting all potential relations given text comprehensive manner. Previous work this area has mainly focused on the extraction isolated relational tuples. Ignoring cohesive nature where important contextual inf...
