This study seeks to design a new and innovative model for school management using the data foundation method, a model that can be an effective aid in solving the problems and challenges facing school principals by using quantum leadership. Designing a quantum leadership model in secondary schools based on data theory is the main goal of this research and seeks to achieve a suitable model for ov...

This paper explores the pedagogical potential of Gamestar Mechanic, a computer game where players learn the principles of game design by making, sharing and reviewing games in the context of an online community of designers. The game has been designed to foster the appropriation of complex language and literacy skills by middle school children. By relying on think aloud interviews and a discour...

Background: Quantum dots are commonly composed of cadmium contained semiconductors. Cadmium is potentially hazardous but toxicity of such quantum dots is not yet systematically investigated. On the other hand, in vitro studies have shown almost complete control of CdSe induced cytotoxicity by ZnS coverage. Toxicity of CdSe quantum dots and controlling this toxicity by ZnS coverage in immature m...

The synthesis and spectroscopic characterization of the mononuclear uranium complex [((ArO)(3)tacn)U(III)(NCCH(3))] is reported. The uranium(III) complex reacts with organic azides to yield uranium(IV) azido as well as uranium(V) imido complexes, [((ArO)(3)tacn)U(IV)(N(3))] and [((ArO)(3)tacn)U(V)(NSi(CH(3))(3))]. Single-crystal X-ray diffraction, spectroscopic, and computational studies of thi...
