3. MÁS ALLÁ DEL RELOJ COMO MODELO DEL SER VIVO: LA DISTINCIÓN MÁQUINA NATURAL Y MÁQUINA ARTIFICIAL EN LEIBNIZ
ABSTRACT During the seventeenth century, the clock seems the most appropriate model for thinking about living beings. The German philosopher G. W. Leibniz (1646-1716), is part of the mechanical tradition that conceives living beings from the clock or the automata’s model, but he establishes an essential distinction between natural and artificial machines.

4. EL DUALISMO CARTESIANO Y SU RELACIÓN CON LA NUEVA MEDICINA A LA LUZ DE SU CORRESPONDENCIA
ABSTRACT Despite of the fact that R. Descartes’s reduction of animals to mere machines can be explained as a logical consequence of his metaphysical and gnoseological starting point, one can argue that this reduction seems to be very difficult to defend, since it appears to be contradictory to our everyday experience. On the other hand, one of the explicit

5. AlradSpectra: a Quantification Tool for Soil Properties Using Spectroscopic Data in R
ABSTRACT Soil reflectance spectroscopy has become an innovative method for soil property quantification supplying data for studies in soil fertility, soil classification, digital soil mapping, while reducing laboratory time and applying a clean technology. This paper describes the implementation of a Graphical User Interface (GUI) using R named AlradSpectra.

6. Determination of maximum zinc recovery of Vazante mine ore by flotation process
Abstract Nowadays, Nexa Resources (ex-Votorantim Metais) operates two zinc mines in Brazil, represented by the Vazante unit in Vazante - MG and the Morro Agudo unit in Paracatu - MG. The present study was carried out at the Vazante unit, where zinc concentrate is produced from a silicate ore called Willemite (Zn2SiO4) through froth flotation processes. The t

7. An SHM approach using machine learning and statistical indicators extracted from raw dynamic measurements
Abstract Structural Health Monitoring using raw dynamic measurements is the subject of several studies aimed at identifying structural modifications or, more specifically, focused on damage assessment. Traditional damage detection methods associate structural modal deviations to damage. Nevertheless, the process used to determine modal characteristics can in

9. The acute hypotensive effect of resistance training performed with machines vs free weights in normotensive men
Abstract AIMS To analyze if different resistance training (machine vs free weight) would have different acute hypotensive effect in active and normotensive individuals. METHODS Fifteen male volunteers (39.2±2.5 years) performed two different resistance exercise protocols, one on machinery and one with free weights for the similar muscle groups and volume

10. Comprobación de la uniformidad de resultados de un equipo de ensayos simultáneos de termofluencia
ABSTRACT The phenomenon of creep occurs in materials that operate under high temperatures and mechanical stresses, causing changes in their structures; such changes are evidenced by a progressive loss of mechanical strength. The characterization of this phenomenon should be performed with appropriate test machines, which are usually dependent on expensive te

11. Comparative evaluation between mechanical and pneumatic cells for quartz flotation in the iron ore industry
Abstract Flotation plays a relevant role in the concentration of iron ores. Conventional flotation technology employing mechanical machines and columns and also circuits combining both types of cells have been utilized in the iron ore industry. The top size of particles in the flotation circuit feed is 150 µm and the slimes below 10 µm are removed as overf

12. A Comparative Study of Cartesian and Delta 3D Printers on Producing PLA Parts
The additive manufacturing processes emerged at the end of the last century and became popular by low-cost 3D printers. The most used printers work on a cartesian configuration, but recently were launched delta machines. These 3D printers use a more complex control system due to their trajectories generation but may present some advantages over the cartesian
