background: the aim of this clinical trial study was to clinically evaluate the use of enamel matrix protein derivative combined with the coronally positioned fl ap to treat gingival recession compared to the subepithelial connective tissue graft by a new method to obtain denuded root surface area. materials and methods: thirteen patients, each with two or more similar bilateral miller class i ...

In recent years we have seen a tremendous growth in the volume of text documents available on the Internet, digital libraries, news sources, and company-wide intranets. Automatic text categorization, which is the task of assigning text documents to pre-specified classes (topics or themes) of documents, is an important task that can help both in organizing as well as in finding information on th...

In the title complex, [Dy(C(7)H(3)NO(4))(C(7)H(4)NO(4))](n), one of the ligands is fully deprotonated while the second has lost only one H atom. Each Dy(III) ion is coordinated by six O atoms and two N atoms from two pyridine-2,6-dicarboxyl-ate and two 6-carboxy-picolinate ligands, displaying a bicapped trigonal-prismatic geometry. The average Dy-O bond distance is 2.40 Å, some 0.1Å longer than...

Experimental phasing of diffraction data from macromolecular crystals involves deriving phase probability distributions. These distributions are often bimodal, making their weighted average, the centroid phase, improbable, so that electron-density maps computed using centroid phases are often non-interpretable. Density modification brings in information about the characteristics of electron den...
