DNA damage and nitric oxide production in mice following infection with L. chagasi
(Elsevier B.V., 2011-08-16)
Leishmania chagasi, which causes visceral leishmaniasis in South America, is an obligate intracellular protozoan. Production of nitric oxide by macrophages during the inflammatory response is one of the main microbicidal ...
Ensemble classification method for structural damage assessment under varying temperature
(SAGE Publications Ltd, 2017)
Vibration-based damage assessment approaches use modal parameters, such as frequency response functions, mode shapes, and natural frequencies, as indicators of structural damage. Nevertheless, these parameters are sensitive ...
On the application of discrete-time Volterra series for the damage detection problem in initially nonlinear systems
Nonlinearities in the dynamical behavior of mechanical systems can degrade the performance of damage detection features based on a linearity assumption. In this article, a discrete Volterra model is used to monitor the ...
Effect of 0.25 ppm Ozone exposure on pulmonary damage induced by bleomycin
(Sociedad de Biología de Chile, 2005)
Use of enzymes to minimize the rheological dough problems caused by high levels of damaged starch in starch-gluten systems
(John Wiley & Sons Ltd, 2016-05)
During wheat milling, starch granules can experience mechanical damage, producing damaged starch. High levels of damaged starch modify the physicochemical properties of wheat flour, negatively affecting the dough behavior ...
Improvement of damage-assessment results using high-spatial density measurements
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005-06)
Model-based damage assessment is based on measuring the distance between experimental and analytical results. In practice, measurements yield only partial mode shapes with respect to the total degrees of freedom present ...
Statistical inference for damaged Poisson distribution
(Marcel Dekker IncNew YorkEUA, 2004)
Influence of the grinding wheel's dive speed on the damage of rectified hardened steels
(Univ Fed Rio de Janeiro, Lab Hidrogenio, 2008-01-01)
The world tendency is the increase of the productivity and the production of pieces more and more sophisticated, with high degree of geometric and dimensional tolerances, with good surface finish and low cost. Rectification ...
DNA damage in peripheral blood mononuclear cells of patients undergoing anti-tuberculosis treatment
(Elsevier B.V., 2012-08-30)
Tuberculosis (TB), a chronic infectious disease, is a major cause of morbidity and mortality worldwide. Expression of iNOS and consequent production of NO during the inflammatory process is an important defense mechanism ...
