1. Quantification of Discontinuities in Welded Joints Using Gamma Tomography
Gamma tomography was used in this work to evaluate the recurrent defects in welding processes in naval steel sheets. It was used a first-generation equipment consisting of a source of Cesium-137, with activity of the order of 200 mCi, coupled to a Thallium-doped Sodium Iodide detector, NaI (Tl). For the study, specimens were produced in ASTM A131-AH36 steel

2. Technical and economic viability of the installation of a hybrid solar-wind generation system in a Brazilian industry
Abstract The demand for electricity is growing worldwide. At the same time, the non-renewable natural resources that account for a large proportion of the global energy matrix are rapidly depleting, which will pose a major challenge in the near future. Therefore, micro-grid models that use renewable energy sources, such as solar and wind, are rapidly develo

12. ONDAS DE MONTAÑA EN LA CAPA LÍMITE PLANETARIA DE LA REGIÓN ANDINA VENEZOLANA
Dynamic and thermodynamic conditions of the planetary boundary layer of the Venezuelan Andean region for the generation of mountain waves are evaluated. The Froude number is calculated by relating the static stability in the presence of orographic supported vertical wind profiles, diagrams and thermodynamic analysis of satellite images. It is found that when
