The study of superconductivity properties enhancement on MgB2 due to TaB2 doping at 2 and 5 at.% levels were carried out, in addition to the effect of atmospheric exposure on MgB2. High energy ball milling was used for the ...

We report recent results on a search for exclusive hadronic decays of charmonium states (χcJ ) decaying into vector-vector meson (χc → V V ), using a sample of 3 million ψ(2S) recorded with the CLEO detector. We present ...

This thesis present the measurement of the mass of the B+ meson produced in pp colli- sions at a centre-of-mass energy of √s = 7 TeV . The data correspond to an integrated luminosity of 5.05 fb−1 collected by the CMS ...

Se diseñaron programas en Matlab, que aplican el método de fotometría de apertura diferencial, a dos imágenes tomadas con un dispositivo de carga acoplada (CCD) en los filtros visible V y azul B, para calcular los parámetros ...

The US Virgin Islands (USVI) lie in the middle of the Caribbean hurricane alley where hurricanes are a yearly threat. Most of the population of each island resides close to the coastline, including most of its hotel and ...

This investigation was focused on the optical properties of pharmaceutical compositions in order to identify correlations for their chemical and physical properties. Two experiments were made, one consisted of tablets at ...

Analytical approximations for the tangential and radial degrees of freedom for curved beams were found by restricting the rotation of the curved beam. Results showed that only the restriction in the rotational degree of ...

This work presents a procedure that has never been published before for producing transparent CuAlO2 thin films. Pulsed laser deposition was used to fabricate films composed of a mixture of Cu2O and Al2O3 in a proportion ...

The effective incorporation of dopant species into ZnO host structure usually induces changes in its physical and chemical properties enabling the establishment of novel multi-functional properties. In the case of doping ...

Mechanochemical reactions of ZnO, NiO, and α-Fe2O3 were carried out in a planetary mill to produce zinc ferrite (ZnFe2O4) and NixZn1-xFe2O4 nanocrystallites. All measurement were made at room temperature under identical ...
