Cu-Doped KCl Unfolded Band Structure and Optical Properties Studied by DFT Calculations.

The unfolded band structure and optical properties of Cu-doped KCl crystals were computed by first principles within the framework of density functional theory, implemented in the ABINIT software program, utilizing pseudopotential approximation and a plane-wave basis set. From a theoretical point of view, Cu substitution into pristine KCl crystals requires calculation by the supercell (SC) method. This procedure shrinks the Brillouin zone, resulting in a folded band structure that is difficult to interpret.

Luminescent Properties of Eu-Doped Hybrid SiO₂-PMMA Material for Photonic Applications.

Hybrid organic-inorganic materials are of great interest for various applications. Here, we report on the synthesis and optical characterization of silica-PMMA samples with different Eu molar concentrations. The optical properties of this material make it suitable for photonic applications.

Low temperature photoluminescence characteristics of chemically synthesized indium doped zinc oxide nanostructures.

Photoluminescence (PL) emission and excitation (EPL) spectra of un-doped and indium (1%) doped 1D zinc oxide nanostructures are studied at different temperatures. The nanostructures reveal a blue emission band attributed to localized donor states. Indium doping enhances the blue emission.

[Stem cell perspectives in myocardial infarctions].

Myocardial infarction is the leading cause of congestive heart failure and death in industrializated countries. The cellular cardiomyoplasty has emerged as an alternative treatment in the regeneration of infarted myocardial tissue. In animals' models, different cellular lines such as cardiomyocites, skeletal myoblasts, embryonic stem cells and adult mesenchymal stem cells have been used, resulting in an improvement in ventricular function and decrease in amount of infarcted tissue.

Five steps to electronic health record success.

There's no denying that the electronic health record is on its way. By taking the following five well-planned steps, healthcare CFOs and CIOs can help make electronic record implementation in their hospitals as smooth as possible: Define "electronic health record" across the entire organization, Set appropriate expectations, Choose the technology carefully, Accept and promote process changes, Carefully plan the transition from paper-based to electronic records.

[Medico-surgical consensus for management of children with gastroesophageal reflux Acapulco, Mexico 2002].

Unlabelled: Gastroesophageal reflux (GER) is a common disease in children less one year old. It is present around 10% of unselected infant population. 40-50% have abnormal 24 h pH monitoring.
