Changes in salivary composition of chemically dependent subjects
(Universidad Latina de Costa Rica, Facultad de Odontología, 2020)
The changes on microstructure and electrical properties of Bi:2223/Ag composite as a function of the granulation and the content of the added silver powder
(Trans Tech Publications Ltd, 2005-12-01)
The Bi-Sr-Ca-Cu-O system has been one of the most studied superconducting ceramic materials for industry applications. The most of the studies with this aim are on silver/ceramic composites, due to the benefits and great ...
Background interference on the color of dental composite materials with different thickness by digital contrast
(2007-08-31)
In this work the color dependence of resin composites with the background color was evaluated. The objective was to measure since what thickness the color of the sample stops being influenced by the color of the background ...

Thermodynamic Analysis of the Phase Separation during the Polymerization of a Thermoset System into a Thermoplastic Matrix. I. Effect of the Composition on the Cloud-Point Curves
(John Wiley & Sons Inc, 2004-04)
The cloud‐point curves of polystyrene (PS) mixed with reactive epoxy monomers based on diglycidyl ether of bisphenol A with stoichiometric amounts of 4,4′‐methylenebis(2,6‐diethylaniline) were experimentally studied. A ...
Effect of different stacking sequences on hybrid carbon/glass/epoxy composites laminate: Thermal, dynamic mechanical and long-term behavior
(Sage Publications Ltd, 2019-08-06)
In the present study, different stacking sequences on hybrid carbon/glass/epoxy composites laminate were examined in relation to thermal, dynamic mechanical and long-term behavior. A positive hybrid effect was found for ...
Changes on transmittance mode of different composite resins
(2009-08-19)
The purpose of this study was to evaluate the transmittance of seven different composite resins. Ten specimens were prepared (10 mm diameter, 2 mm thickness) for each experimental group, as follows: G1- Charisma® A 2 ...

Optical transition probabilities and compositional dependence of Judd-Ofelt parameters of Er3+ ions in fluoroindate glass
(1995-09-01)
Fluoroindate glasses containing 1, 2, 3, and 4 mol% ErF3 were prepared in a dry box under an argon atmosphere. Absorption spectra of these glasses at room temperature were obtained. The Judd-Ofelt parameters Ωλ (λ = 2, 4, ...
