Influence of Platform and Abutment Angulation on Peri-Implant Bone. A Three-Dimensional Finite Element Stress Analysis

The aim of this study was to evaluate stress distribution on the pen-implant bone, simulating the influence of Nobel Select implants with straight or angulated abutments on regular and switching platform in the anterior maxilla, by means of 3-dimensional finite element analysis. Four mathematical models of a central incisor supported by external hexagon implant (13 mm x 5 mm) were created varying the platform (R, regular or S. switching) and the abutments (S, straight or A, angulated 15 degrees). The models were created by using Mimics 13 and Solid Works 2010 software programs. The numerical analysis was performed using ANSYS Workbench 10.0. Oblique forces (100 N) were applied to the palatine surface of the central incisor. The bone/implant interface was considered perfectly integrated. Maximum (sigma(max)) and minimum (sigma(min)) principal stress values were obtained. For the cortical bone the highest stress values (sigma(max)) were observed in the RA (regular platform and angulated abutment, 51 MPa), followed by SA (platform switching and angulated abutment, 44.8 MPa), RS (regular platform and straight abutment, 38.6 MPa) and SS (platform switching and straight abutment, 36.5 MPa). For the trabecular bone, the highest stress values (sigma(max)) were observed in the RA (6.55 MPa), followed by RS (5.88 MPa), SA (5.60 MPa), and SS (4.82 MPa). The regular platform generated higher stress in the cervical periimplant region on the cortical and trabecular bone than the platform switching, irrespective of the abutment used (straight or angulated).

Managing organizations for sustainable development in emerging countries: an introduction

This introduction article is for the special issue Managing organizations for sustainable development in emerging countries: natural resources, biodiversity, and climate change' in the International Journal of Sustainable Development & World Ecology and presents an introduction to the topics and summarizes accepted contributions in the special issue. The accepted works may contribute with organizational management in the search for more sustainable organizations. The works focus on the challenges of managing organizations in a context of degradation of natural resources, loss of biodiversity, and climate change. Accepted papers discuss these issues, based on the reality of emerging economies (e.g. Brazil, India, and China).

Egocentric speech in the works of Vygotsky and Piaget: educational implications and representations by teachers

This paper presents an applied qualitative and quantitative study and seeks to understand egocentric speech according to Vygotsky and Piaget and, through a literature review, the educational implications of Vygotsky and Piaget’s ideas. Additionally, the representations of these ideas by fifteen teachers of basic education are investigated. It is important to understand egocentric speech in Vygotsky and Piaget. Despite the differences in how they conceive its nature, functions and implications, for both, egocentric speech is intrinsically linked to and facilitates our understanding of child development. Regarding the representation of teachers who criticized children who used egocentric language, when teachers established any negative consequences of such language, they attributed it to the affective and moral aspects as well as to cognition. However, their approach was more practically oriented than those found in the psychological theories addressed. Therefore, this study aids in understanding the limits and scope of teacher-training courses.

A discursivização em Wall.E: sociedade, tecnologia e poder

This article consists in a discourse analysis of the feature film in animation Wall.e produced by Pixar in association to Disney in 2008. Pixar has been known to produce films that contain various discursive levels, making its products appealing not only for children, but also for adults. However, Wall-e proves to be a masterpiece in Pixar carrier, because it is the one which focuses on the analysis and critique of contemporary society associated with technological development. For this, the plot has as its starting point the question of sustainability and unbridled consumerism. But the film expands the debate, tracing the relationship between technology and humanity, discussing how one affects the other. The project therefore aims to show how the animation works such concepts and constructs his discourse. To this end, the work seeks to identify the signs that make up the discourse and draw the intertextuality between WALL.E and other works that also discuss the same elements such as Stanley Kubrick‟s 2001 - A Space Odyssey (1968)

Orcs Inc. - jogo de tabuleiro empresarial: capacitação profissional através do lúdico

A proposta deste trabalho é criar um Jogo de Tabuleiro Empresarial voltado para a capacitação de profissionais de micro e pequenas empresas em comunicação, juntamente com a aluna de Design da Unesp - Bauru, Tatiana Kurokawa Hasimoto. Observando o poder dessa ferramenta em outras áreas do conhecimento (como administração e empreendedorismo) exploramos o potencial da área de comunicação para a criação de um Jogo de Tabuleiro Empresarial, voltado para a capacitação e seleção. O trabalho tem como base um mapeamento de microempresas da cidade de Bauru, realizado pelo Núcleo de Opinião da UNESP, coordenado pela Profª Drª Célia Maria Retz Godoy dos Santos, onde foi possível perceber a falta de conhecimento sobre a área de comunicação por essas empresas. O objetivo é mostrar a importância da comunicação e principalmente como o profissional de Relações Públicas pode atuar nessas empresas
