Characteristics of the double-torsion test to determine the R-curve of ceramic materials
(2006-10-01)
Double-torsion tests were carried out on a commercial ceramic floor tile to verify whether this test is suitable for determining the R-curve of ceramics. The instantaneous crack length was obtained by means of compliance ...

Comparison of proton energy loss in thick absorbers in terms of a reduced calibration curve
(Elsevier B.V., 2011-10-01)
Monte Carlo simulations are essential for the support of particle experiments and developments of novel particle registration systems ranging from detectors developed for high-energy physics experiments at CERN to those ...
Effects of physical habitat degradation on the stream fish assemblage structure in a pasture region
(Springer, 2006-12-01)
We compared the fish assemblage structure from streams with different intensities of physical habitat degradation and chemical water pollution by domestic sewage in southeastern Brazil. Eight streams (R1-R8) showing less ...
Study of the dimensions of double-torsion test specimens
(ABM, ABC, ABPol, 2008-09-01)
Double-torsion tests were carried out to ascertain whether a thin test specimen would affect the results of this test. The tests involved two test specimen sizes, one with a thickness five-fold greater than the particle ...
Stand-alone posterior ressection of lumbar hemivertebrae: case report
(Drunpp-sarajevo, 2012-01-01)
Background: In this case report we presented the stand-alone posterior approach for hemivertebra resection with unilateral laminar hooks.Case report: The patient was male and five years old. The coronal and sagital X-Rays ...
Metal-insulator transition in Nd1-x Eu-x NiO3 probed by specific heat and anelastic measurements
(American Institute of Physics (AIP), 2011-04-01)
Oxides RNiO3 (R - rare-earth, R not equal La) exhibit a metal-insulator (MI) transition at a temperature T-MI and an antiferromagnetic (AF) transition at T-N. Specific heat (C-P) and anelastic spectroscopy measurements ...
Relaxor behavior in multiferroic BiMn2O5 ceramics
(American Institute of Physics (AIP), 2011-10-15)
In polycrystalline BiMn2O5, a broad thermal stimulated depolarization current curve has been observed in the range from 10 K to 300 K and the pyroelectric coefficient determined. In magnetic susceptibility measurements ...
Important GABAergic mechanism within the NTS and the control of sympathetic baroreflex in SHR
(Elsevier B.V., 2011-01-20)
Inhibitory neurotransmission has an important role in the processing of sensory afferent signals in the nucleus of the solitary tract (NTS), particularly in spontaneously hypertensive rats (SHR). In the present study, we ...
Sensitivity, specificity and predictive values of linear and nonlinear indices of heart rate variability in stable angina patients
(2012-10-31)
Background: Decreased heart rate variability (HRV) is related to higher morbidity and mortality. In this study we evaluated the linear and nonlinear indices of the HRV in stable angina patients submitted to coronary ...
