Comparação da razão carga/deflexão entre fios ortodônticos de Ni-Ti termoativados 0,014”x0,025” e 0,016”x0,022”

The knowledge of the mechanical properties of nickel-titanium (NiTi) termoactives of the more accessible of the domestic market is still limited. Given this, the objective of this study was to evaluate and compare through deflection tests in brackets NiTi wires 03 term rectangular gauge 0.014 '' enabled x 0.025 '' and 0.016 '' x 0.022 '' of different brands (MORELLI (R), ORMCO (R) ORTHOSOURCE (R), ORTHOMETRIC (R), EURODONTO (R) and ADITEK (R)). All tests were carried out on universal testing machine EMIC DL 2000 under identical conditions and controlled at a temperature of 36 degrees C +/- 0.5 degrees C. Five measurements (N= 5) were performed for each thickness/wire tag that was deflected up to a limit of 4.0mm at a speed of 1.0mm/min. Each 0.2mm (round trip) of corresponding strength measured deflection for the construction of the graph of force x deflection at Tesc program version 3.04. Each graphic was evaluated according to the following variables: beginning of the Martensitic transformation (cN and mm), maximum strength (cN), the beginning and end of the plateau of deactivation (cN and mm) and length (mm) plateau. The average and standard deviation were calculated for all variables and statistical analysis was made by ANOVA tests 2 criteria and Turkey or Kruskal-Wallis and Dunn, a 5% level of significance. The results showed that the tests of 0.014 '' x0.025 '' ORTHOMETRIC (R) brands and ORMCO (R) showed the best results, as well as the wires of the MORELLI (R) and ORTHOSOURCE (R) to wires 0.016 '' x0.022 ''. In General, the gauge wires 0.014 '' x0.025 '' showed strength levels on the plateau of deactivation to 6 x smaller than 0.016 '' x0.022 '' caliber.

PREPARATION AND CHARACTERIZATION OF A COMPOSITE OBTAINED THROUGH Ti (IV) AND PHOSPHORIC ACID

This paper describes the preparation and complementary characterization of a composite formed from the activation of titanium isopropoxide by phosphoric acid and deionized water (TiP). Techniques such as, X-ray diffraction (XRD), Raman, electronic (UV-vis) and Scanning electron microscopies (SEM) were used for characterization of this new composite formed. In the X-ray diffractogram of TIP was observed four intense peaks. A strong absorption was observed in the region 362-445 nm. The scanning electron microscopy of TiP, shows that the prepared material consists mostly of a cluster of spherical particles with diameters ranging from 2.35 to 2.60 mu m.

Efeitos da cultura organizacional no desenvolvimento dos modelos de governança corporativa

Corporate governance can be understood like a management model that aims to build a good relationship between managers, controllers, minority shareholders and other stakeholders. Implement corporate governance in an organization often requires a cultural change. Corporate governance as an organizational model needs reinforce cultural behaviors of its members so as which support the principles and values that increment the relationship between the organization and its stakeholders. The process of corporate structuring of an organization is largely determined by culture. Being the culture a set of organizational values that distinguishes one organization of other, it is natural that these organizations find adjustment difficulties during the implementation of international values. The organizations in the context of corporate governance can t think and act over themselves, but instead must think and take action on a set of actors who are strongly linked with them in order to achieve the same goals and objectives planned.

A construção do conhecimento sobre governança corporativa: uma análise bibliométrica

Presents a survey of scientific production about the subject corporate governance, using the Bibliometric analysis of theses and dissertations collected in the digital libraries of the Sao Paulo State University (Unesp), Campinas State University (UNICAMP) and University of Sao Paulo (USP). Through the data collected were identified, based on Bibliometric indicators, the origin of authors, the authors more cited, the thematic area of authors, and the construction of co-citation network.
