Introduction: This paper considers that information science (IS) literature covers a diversity of thematics with low emphasis on researches about conducting research. The study analyzes the scientific production of authors who investigate about research methodology in the information science (IS) literature, and the references used to lay the foundation of the methodological issues regarding the area. It discusses the methodological and epistemological positions of the leading researchers highlighted as the most productive investigators on the subject in the country. Method: The research adopts the content analysis coupled with metric studies to contextualize the indicators related to productivity, to the types of authorship and citation analysis. The bibliographic coupling method is considered an analysis mode which analyzes concomitant citations. It develops a theoretical framework about the importance of scientific production analysis in different knowledge fields. The study investigates, from a theoretical perspective, the concepts about research methodology and the complementarity between methodology and epistemology in conducting research. Results: The results of the analysis showed that the production of the highlighted authors presents the methodology as a thematic focus to be applied to IS contexts, as well as a research object in the field. The prominent productivity of the authors is justified especially by deepening the meta studies about the ways to conduct research in IS. This study also identifies a trend to single-authored studies about the theme. Conclusions: The research considers that meta studies and applied and methodological studies are important to recognize a consistent theoretical and practical core in the IS area. Regarding the epistemological influences identified by the citation analysis, the study observes that the critical rationalist epistemology and the social and political epistemology are highlighted in the construction of the theoretical framework of the most productive authors.

Technological development in the IT and telecommunications sectors have transformed the way organizations communicate with their audiences. Social Media allow the exchange of information instantaneously, in a communication from many to many. With few studies in the area, many companies venture into the social media without a strategy and a generally end up denigrating their image itself. Thus, this study was conceived from the idea of contributing, analytically, based on the main concepts of Public Relations so the organizations effectively take advantage of their online presence to generate relationships, more specifically, on Twitter.Twitter is a social media with a mature public, requiring dynamics of information and quick answers, based on dialogue, referring to the idea of text messages (SMS). To better expose the results of this research, three organizations with expertise in twitter were chosen: Bradesco , Positivo Informática and Ponto Frio. The choice of case studies was based on the different segments that each one operates and that they are large companies with reputable commercial operations in the Brazilian scenario. To analyze their profiles, several authors were studied, like Fábio França, Maria Aparecida Ferrari, Margarida Kunsch e Marlene Machiori.The intent of the analysis of the Twitter profiles of these organizations is to understand whether they are using strategies for creating and maintaining relationships with your followers and how this occurs from specific categories, as other companies have committed serious errors and impairing their business because of mismanagement in social media. Therefore, the profiles were analyzed from the netnográfica methodology. As a result, it was observed that organizations have not yet developed the character of relationships in social media , treating this channel as another advertising channel It was observed that Positivo Informática has no specific strategy for Twitter...

O emprego significativo de polímeros na sociedade moderna causou um grande desenvolvimento tecnológico em torno de sua produção a partir do petróleo. Contudo a limitação crescente de disponibilidade e as altas sucessivas do preço do petróleo têm estimulado, cada vez mais, novas pesquisas no desenvolvimento de biopolímeros provenientes de recursos renováveis. O biopolímero dextrana tem origem da conversão do substrato promovida pela enzima dextranasacarase que é secretada por micro-organismos principalmente pertencentes à família Lactobacillaceae. O objetivo desta pesquisa tem por meio do levantamento bibliográfico reunir conteúdos relacionados ao biopolímero dextrana, a enzima dextranasacarase, os micro-organismos produtores e suas aplicações industriais. Devido a algumas características da dextrana (Hidrofobicidade, estabilidade, pureza e habilidade de formar soluções claras e estáveis, entre outras), a mesma apresenta um grande leque de aplicações na indústria farmacêutica, alimentícia, petroquímica e química. As pesquisas que vinculam a dextrana às aplicações industriais estão em plena expansão e sabendo que a produção de dextrana é proveniente de recursos naturais renováveis e de origem microbiana, o momento atual é favorável para um aumento de sua produção, causando a valorização deste biopolímero no mercado nacional e internacional

The research involving new materials has always been considered as a differential in the development of a technology company. This occurred naturally since ancient times, often motivated by reasons of a certain age, where the most common material used was also the name of your time and may be cited as an example the Bronze Age, and later was the Iron. Currently, the use of firearms are they used in resolving conflicts between countries, or a more equivocal, as an instrument of social banditry make innovations in the area of shielding welcome, whether for personal use, in the form of vests or vehicle such as cars, tanks and even aircraft. In this context, is a Silicon Carbide Ceramic, with low density and high hardness. Thus, the aim of this study is the evaluation and comparison of these materials, seeking to improve their properties by means of additives such as boron and silicon metal and amorphous YAG. For this work, the specimens were pre-shaped by means of uniaxial later to be referred for isostatic pressing and sintering. The maximum percentage for each additive was 5%, except for the YAG whose percentage was 8.2% (mass percentage). All compositions were subjected to the same tests (x-ray diffraction, apparent density, optical microscopy, Vickers hardness, scanning electron Microscopita), so that one could draw a comparison between the materials under study, samples that showed better mechanical properties and micro structural, related here by hardness testing and microscopy (optical and SEM) were the silicon carbide doped with YAG and alumina samples, demonstrating the potential of these materials for ballistic protection. Other compositions have high porosity, which is highly undesirable, since in order to harmful influences on the mechanical properties discussed below
