2. Electromagnetic Core Analysis of a DFIG State-Feedback Power Controller
Abstract The energy demand by modern society grows every day that allied with sustainable development requires the use of alternative sources in the new energy matrix. In this context, the wind energy as source by using a doubly-fed induction generator stands out due to its operational savings but still faces some conflicts in its power control. This paper p

4. Influence of artificial lights on the orientation of hatchlings of Eretmochelys imbricata in Pernambuco, Brazil
ABSTRACT Sea turtle hatchlings, in natural abiotic conditions, emerge from their nests at night and go directly to the sea, following the moonlight’s reflection in the ocean. Increased human activities such as tourism and artificial lights on the coasts, however, have interfered with the ability of sea turtle neonates to find their correct destination, neg

5. Multistage Deep Drawing with Ironing of Al-killed AISI 1040 Graded Medium Carbon Steel: a Parametric Study
Analysis of multistage deep drawing with ironing was made while manufacturing of cups from 12 mm thick, 60 mm diameter circular blanks of Al-killed AISI 1040 graded medium carbon steel. Quality requirements of the steel in heat treated condition were examined in terms of tensile properties, formability characteristics, and formability limit diagram. Drawabil

6. Analytic Approach to Alloys Thermodynamics: Ternary Cu-Ga-Ni system
In this paper are presented the results of the calculation of thermodynamic properties in liquid state for ternary Cu-Ga-Ni alloys using the newest version of general solution model. Calculation was carried out in temperature interval 1473-2073 K, along 3 cross sections from corner of each metal, with ratios between two other metals 1:3, 1:1 and 3:1. Partial

7. Instalación de la escuela monocultural en la Araucanía, 1883-1910: dispositivos de poder y Sociedad Mapuche
Abstract This article results from a historiographical study about the establishment of a monocultural school in Araucania region, in south Chile, between 1883 and 1910. It aims to analyse the school as the main power device which allowed legitimizing the establishment and implementation of the Chilean national curriculum in Mapuche territory. We argue that

8. Caracterização batimétrica e fisicooceanográfica do canal de acesso ao porto de Cabedelo/PB: uma análise ambiental ao derrame de óleo
The State of Paraíba is one of the most dynamic states of Brazil, strategically located in the northeast, is notable for the excellent potential for integration of different transportation modes forming the states of Rio Grande do Norte, Pernambuco and Alagoas. The dynamic that occurs with port activity causes changes in the space where it is installed. And

11. Improving the solubility of the antichagasic drug benznidazole through formation of inclusion complexes with cyclodextrins
This study describes unpublished research on improving the solubility of benznidazole by the formation of an inclusion complex. The cyclodextrins selected were αCD, βCD, γCD, HPβCD, RMβCD and SBβCD. All complexes were obtained in solution, presenting 1:1 stoichiometry according to the phase solubility diagram. The highest association constants were obt

12. Vila Maria Formation (Silurian, Paraná Basin, Brazil): integrated radiometric and palynological age determinations
Fresh shale samples taken from a well-known outcrop section of the Silurian Vila Maria Formation, located on the northeastern margin of the Paraná Basin (Três Barras Farm, Goiás State, central-western Brazil), have been analysed for both palynological and radiometric age determinations. The rocks yielded a fairly diverse, age-definitive cryptospore assemb
