Bilim, teknoloji ve mühendislik temelli içeriklerin küresel boyutta giderek artan önemi STEM (Science, Technology, Engineering and Mathematics) yaklaşımının eğitim içeriklerinde yer bulmasına yol açmıştır. Bu nedenle temel eğitimin felsefesi doğrultusunda güncellenen ilkokul ortaokul fen bilimleri dersi öğretim programında programa göre hazırlanan ders kitaplarında yerini ortaya koymak bu çalış...

In the title compound, [Fe(C(14)H(12)NOSe(2))(2)], the Fe(II) ion (site symmetry ) is four-coordinated by two N,O-bidentate Schiff base ligands, resulting in a slightly distorted trans-FeN(2)O(2) square-planar coordination for the metal ion.

The chemical bond and structural features for the most important classes of solid products obtained by reacting chalcogen donors with dihalogens and interhalogens are reviewed. Particular attention is paid to the information the FT-Raman spectroscopy can confidently give about each structural motif considered in the absence of X-ray structural analyses.

Double-strand DNA breaks are the most lethal type of DNA damage induced by ionizing radiations. Previously, we reported that double-strand DNA breaks can be enzymatically produced from two DNA damages located on opposite DNA strands 18 or 30 base pairs apart in a cell-free double-strand DNA break formation assay (Vispé, S., and Satoh, M. S. (2000) J. Biol. Chem. 275, 27386-27392). In the assay ...
