Sugar cane nutrient distribution analysis
(2011)Neutron Activation Analysis (NAA), Molecular Absorption Spectrometry (UV-Vis), and Flame Photometry techniques were applied to measure plant nutrient concentrations of Br, Ca, Cl, K, Mn, N, Na and P in sugar-cane root, ... -
Comparative study of the proton beam effects between the conventional and Circular-Gate MOSFETs
(2012)The study of ionizing radiation effects on semiconductor devices is of great relevance for the global technological development and is a necessity in some strategic areas in Brazil. This work presents preliminary results ... -
Exploring the potential of the São Paulo potential
(2010)© 2010 Owned by the authors, published by EDP Sciences.Recent development of an imaginary potential based on the São Paulo potential is briefly presented. Further developments of the model in order to describe weakly bound ... -
High natural radiation in Brazilian sands
(2012)The present work investigated Brazilian beach sands in order to analyze the total external natural radiation dose using a gamma-ray spectrometry technique. The activities from the radionuclides 40K and the elements from ... -
Comparative experimental study between tensile and compressive uniaxially stressed nmugfets under x-ray radiation focusing on analog behavior
