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.

This paper discusses the different forms and conditions of incorporating collections from the judiciary by executive bodies. For such, we use the custodial history of the Juízo de Órfãos de São Paulo archives as a reference. An instance of the Brazilian justice between the 16th and 20th centuries, the Juízo de Órfãos de São Paulo is currently fragmented in several institutions of custody and under different denominations. Similarly, other archives from judiciary bodies underwent similar processes for custody transfer. However, this type of situation is not restricted to the past: nowadays, even under legally established norms and guidelines for the implementation of document management programs, it is still possible to find, recurrently, the adoption of similar procedures for the incorporation of collections. We therefore intend to establish a parallel between these two moments and the Brazilian archival legislation in force.

In this article we aimed the identification and the analysis of the “textual configuration aspects” from the speeches of the “high authorities” of public instruction in São Paulo contained in Annuarios do ensino do estado de São Paulo, centrally those published between 1907 and 1927, on the direction of public instruction and its teachers statewide. This formulation resulted from the need to search the peculiar aspects of these discourses, that is, from a conductor thread through which and by vitue of which these discourses have been produced. It was concluded at the end, the common orientation mentioned to speeches was to bring the idea together, a sense of unity to the sphere of public education in the state, which would characterize the called school apparatus in São Paulo.
