A previous study has shown that the mode shapes of a beam are more sensitive to damage than other vibrational parameters, thus making them better suited for crack identification purposes. However, they have the disadvantage of being more difficult to

Experimental identification of structural changes and cracks in beams using a single accelerometer

Autor: Juan E. Perez Ipiña, Carlos Alberto Bavastri, Marcus Vinícius Manfrin de Oliveira Filho

Several advances in the structural health monitoring field and in crack identification techniques were achieved in recent years. Nonetheless, the use of those techniques for crack identification in beams by the industry is still modest. A few reasons

RETRACTED: Intracellular distribution of p300 and its differential recruitment to aggresomes in breast cancer

Autor: María Eugenia Fermento, Norberto Ariel Gandini, Juan E. Perez, Horacio V. Maturi, Alejandro Carlos Curino, Maria Marta Facchinetti, Cecilia A. Lang

Publikováno v: Experimental and Molecular Pathology. 88:256-264

It has been recently suggested that p300 cytoplasmic redistribution and degradation are important for controlling the availability and activity of the protein as a transcriptional coactivator. As a step towards determining the functional relevance of

Geometrical effects on lamellar grey cast iron fracture toughness

Autor: Juan E. Perez-Ipiña, G. Bertolino

Publikováno v: Journal of Materials Processing Technology. 179:202-206

Lamellar grey cast iron presents a non-lineal load-displacement record. This macroscopic behaviour is originated in the complex microstructure of these materials that are formed by two phases (one metallic matrix with distributed graphite lamellaes)
