Investigando concepções e propondo ações formativas para a natureza da ciência

Apresenta os resultados de uma investigação que explorou as percepções de alunos de Ensino Médio de uma escola pública de um município do interior paulista quanto à natureza da ciência. A partir desse diagnóstico, que revelou distorções, foi elaborado um minicurso que tem como base a história da atomística, a partir da qual se faz emergir as concepções da História e Filosofia da Ciência. O minicurso explora, ainda, uma abordagem situações envolvendo questões éticas na ciência. Pretende-se, a partir desse minicurso, fornecer contribuições que favoreçam a clarificação das distorções, estimulando o pensamento crítico para questões pertinentes a temas envolvendo as relações entre ciência, tecnologia, sociedade e ambiente.

Blogs para adolescentes e a articulação dos PCNs na produção escrileitora do ensino médio

The new National Curriculum of Basic Education in Brazil Parameters (PCNs- br) propose the curriculum reformulation of the High School in thematic areas encompassing competences and abilities. In this aspect the goal of this article is to verify the effects and meaning of the speeches posted on Folhateen's Blog (http://blogdofolha teen.folha.blog.uol.com.br/), to analyze if the practices of reading and writing, taken in this application, can be contemplated on the basic goals of the PCNs from the Languages area, codes and its technologies. It wonders of the using of media blogs for High School students as articulators of the Portuguese Language contents' study. It is possible to verify that the blogs offer its own languages and the expression of knowledge and power. They put the high school student before the articulation of several cross-cutting themes that promotes the interdisciplinarity. It points the need of a teacher's support so in a matted discursive voices the student won't be distracted, drift and paraphrase, but the interpretation and "new" methods of reading and polysemy. The theoretical framework is composed by the authors Foucault, Pecheux, Orlandi and Coracini.

Restoration of endodontically treated teeth

The restoration of endodontically treated teeth is one of the most challenging situations of the dentist`s clinical practice, because it involves procedures related to several areas, such as Endodontics, Operative Dentistry, and Prosthetics. These restorations aim to replace the structures lost during endodontic surgery and access to both the pulp chamber and root canal system during the instrumentation, as well as the removal of the carious tissue and temporary restorations. It is also important to remember that the prognosis of endodontically treated teeth depends not only on endodontic treatment success itself, but also on the amount of remnant tooth tissue and the definitive restoration that will be placed onto the dental element.

Interactions between restorative dentistry and periodontics: luting post nonmetallic (Part II)

Endodontically treated teeth have necessary use of intracanal posts. Due to the constant need and search for esthetic materials with properties similar to tooth structure remaining fi berglass posts esthetic came good these shortcomings and are increasingly used as a fi rst option for prosthetic rehabilitation. In this case report is described step by step how to perform the cementation of a nonmetallic post and core construction for making a piece prosthetic onlay in a simplifi ed way, by choosing the self-etching cementation technique.

Visão contemporânea sobre pinos anatômicos

As an alternative to improve the adaptation of prefabricated posts in flared canals and weakened roots, the option is for relining prefabricated pin, known as a technique of anatomical post. This technique, which can be made with composite resin increases the adjustment post to the walls of the canal and reduces the cementing line, causing the retaining post is less dependent on the mechanical properties of the cementing agent. This article aims to provide an overview of anatomical posts, specifically in the last two decades, based on studies extracted from Scielo, Scopus and Pubmed, referring to the following terms of MeSH Data Base: custom made fiber post, indirect fiber glass posts, root canal therapy and post and core tecnique. According to the literature review in this article, it can be concluded that this technique has been used by several authors and has been shown effective and promising, it creates an individualized retainer with better adaptation and decreased mechanical imbrication cementing line .

Chega de Fiu Fiu: o papel do ciberfeminismo na construção do feminismo na era da Web 2.0

Esta monografia tem como objetivo abordar o ciberfeminismo, um fenômeno social e político recente, na construção do feminismo na era da Web 2.0 a partir de conteúdos produzidos por mulheres, para mulheres e sobre mulheres e veiculados na internet por meio de blogs e redes sociais. Para isso, será feito um estudo de caso do think tank Olga e seus desdobramentos em blog, redes sociais e campanhas contra o assédio sexual batizadas de Chega de Fiu Fiu. Para analisar esse material, o pensamento pós-estruturalista foi o escolhido, junto ao saber situado, por suas afinidades com a perspectiva feminista

Razão e paixão: necessidade e contingência na construção da vida ética

This text, essayistic character, aims to make some reflections on the dispute or supposed conflict that exists between two elements that have become essential in the constitution of the philosophical domain, in order to assess their contribution in the ethical field. On the one hand, we find the rational dimension, which is marked and has acquired certain predominance in western thought. On the other hand, the dimension of passion, that throughout the history of philosophy, has been subject to exclusion and devaluation, making it as if it were an obstacle to the formulation of ideas and universal values true and substantial. If one looks at the world seeing them or giving it a necessary and essential character, the other tends to recognize the contingent aspect of reality, seeing in it the possibility of accidental and uncertain.

Fracture resistance of simulated immature teeth after different intra-radicular treatments

The aim of this study was to evaluate the fracture resistance of simulated immature teeth after different intra-radicular treatments. Crowns and roots of bovine incisors were cut transversally and removed to simulate immature teeth. Root canal preparation and flaring were performed using a bur in crown-apex and apex-crown direction. The samples were distributed into 5 groups (n=10): Positive control (PoC) - no root canal flaring or filling; Negative control (NeC) - teeth were sectioned and their root canals were flared; Direct anatomical glass fiber post (RaP) - #2 Reforpost main glass fiber post relined with composite resin; Double tapered conical glass fiber posts (ExP) - #3 Exacto glass fiber post; and #2 Reforpost main glass fiber + Reforpin accessory glass fiber posts (RrP). In RaP, ExP and RrP, 4.0-mm apical plugs were done with MTA Angelus. The specimens were embedded in polystyrene resin inside cylinders and the periodontal ligament was simulated with a polyether-based impression material. The specimens were submitted to compressive fracture strength test (0.5 mm/min at 135° relative to the long axis of the tooth) in a servo-hydraulic mechanical testing machine MTS 810. Data were subjected to one-way ANOVA and Dunnett's C or Tukey's tests (α=0.05). The control groups (PoC and NeC) showed lower fracture strength than the experimental groups. NeC presented the lowest resistance and ExP presented the highest resistance among the experimental groups. The flaring procedures produced a detrimental effect on the fracture resistance of the bovine teeth. Glass fiber intra-radicular posts increased significantly the fracture resistance of simulated immature teeth.

Comunicação empresarial e relações públicas: a construção de relacionamentos no contexto do Facebook

Currently with the context of the Internet, especially on online social networks, it is observed that people and companies are establishing relationships both online and offline.
