In this work of tensile strength was evaluated the efficacy of 4 cements (S. S. White zinc phoshate, Ketac Cem Easymix glass ionomer, RelyX Luting 2 composite resin/glass ionomer and Panavia 21 TC special acrylic resin) used to fix NiCr crowns to usinated titanium alloy abutments. Were used 40 abutments distributed in groups of 10 elements, to each material. The mechanical essays were developed at a MTS 810 universal machine, adjusted to a 0.5 mm/m velocity. The ANOVA applied to data pointed out the existence of significant differences between groups; the subsequent Tukey´s test (p<0.05) also detected significant differences, except at comparisons of phosphate versus RelyX and phosphate versus Ketac Cem. The better performance was presented by Panavia 21 (1,127.996 N); RelyX (478.197 N) showed itself similar only to phosphate (430.662 N), wich had a performance similar to that of Ketac Cem (227.705 N).

Always seeking the maximum profit under the reduced production time and lower number of failures, companies are increasingly evolving and going after continuous improvement in order to remain competitive in the market. Thus, increasingly there is investment in the management system Lean manufacturing. Lean system is very important, because through it, the maximum value is added in the final product. Being measured by the efficiency and reducing failures to zero. In the studied company, Lean manufacturing system came into effect through the kanban system for purchasing, control and distribution of bulk material used in the assembly of the final product, which are earth-moving machines. It is very important to check the great change made in the company with the implementation of kanban. All inventory management becomes visual, elements are arranged in an organized manner, with addresses in structures, calculated in special boxes and finally, assemblers have the guarantee of an item supply, with the distribution cars located on their assembly area. This study participates effectively assuring the supply. Avoiding any failure on the lack of material, non-compliance of delivery times to the customer and maintenance of over-stock or obsolete inventory, in which case both cause financial loss to the company

The discussion of this paper focuses on the search for demarcation of the Momo merriments in the city of São Paulo between 1960 and 1964, aiming to apprehend their specific traits at that juncture. It is known that the Brazilian Carnival, and in its sphere the São Paulo City one, has been steadily becoming enshrined in profile by popular segments. However, in that decade onset such festivities were going through certain peculiarities because it was a period characterized by many changes. The city of São Paulo, particularly, was experiencing an accelerated process of urbanization and consequent massification, as well as a moment of significant expansion of the cultural industry and mass communication means. Were the Momo revels immune to this process? What was the profile of these amusements in the city?

Metidos a movimentação dentária induzida. Métodos: utilizou-se 30 ratos Wistar, divididos em três grupos (GI, GII e GIII), compostos por 10 animais cada e sacrificados, respectivamente, 7, 14 e 21 dias após o início do experimento. Os valores médios individuais dos grupos experimentais foram comparados com seu respectivo controle por meio do teste Mann-Whitney. Comparou-se, também, os valores entre regiões em um mesmo período de tempo e, ainda, entre períodos de tempo diferentes em uma mesma região através da Análise de Variância (ANOVA), Kruskal-Wallis e subsequente teste de Tukey. Resultados: os grupos GI e GII exibiram a dimensão do LPD diminuída nas regiões apical da raiz mesiovestibular e cervical da raiz distovestibular, e aumentada nas regiões cervical da raiz mesiovestibular, apical da raiz distovestibular e média de ambas as raízes. Conclusão: a diminuição e o aumento da dimensão do LPD evidenciada em uma mesma raiz — mesiovestibular ou distovestibular —, caracterizou o movimento dentário no sentido de inclinação. As três regiões, apical, média e cervical, comparadas entre si em cada período de tempo, bem como os três períodos de tempo, 7, 14 e 21 dias, comparados entre si em cada região, confirmaram o movimento de inclinação em GI e GII, e a diminuição gradual da intensidade dos fenômenos de GI para GII, até o restabelecimento da normalidade dimensional em GIII.

This paper conducts an analysis of the cover of the first issue of Trace magazine, conceived and edited by a group of graphic artists from Bauru (SP) published in November 1987 from the study proposed by Donald Norman (2008) especially through the visceral, behavioral and reflective approaches. This is a critical exercise, based on the study, of the use and application of the theory of Norman, which focuses on the development and focusing the scope of graphic design.
