A presente invenção compreende a descrição de uma nova seqUência regulatória provida para direcionar a expressão de uma seqUência de nucleotídeo, tal como genes estruturais, em raízes de plantas, incluindo monocotiledôneas e dicotiledôneas. Mais especificamente a invenção refere-se a seqUências regulatórias de polinucleotídeos isoladas de plantas de café que são capazes de iniciar e acionar a transcrição de polinucleotídeos, e ao uso destas seqUências regulatórias no direcionamento de transcrição de polinucleotídeos endógenos e/ou heterólogos para tecidos radiculares e produção de polipeptídeos. A invenção descreve ainda construções de DNA que contém o promotor de um gene que codifica uma proteína da família das peroxidases de plantas de café que está operacionalmente ligado a um gene heterólogo e/ou endógeno. Além disso, a invenção diz respeito ao uso destas construções na forma de vetores de expressão, vetores recombinantes e em plantas, células vegetais ou protoplastos transgênicos. A invenção ainda descreve um método utilizando tais construções contendo o promotor de um gene que codifica uma proteína da família das peroxidases de plantas de café para produção de plantas, células vegetais ou protoplastos transgênicos.

Neste trabalho a quatro mãos, Antonio Vicente Marafioti Garnica e Luzia Aparecida de Souza tentam compreender de que modo a história do ensino da Matemática influenciou os métodos didáticos atualmente empregados, principalmente na educação básica, mas também na formação e no direcionamento dos professores. De acordo com os pesquisadores, após as reformas educacionais realizadas na França na década de 1790, em grande parte sustentadas pelos ideais iluministas, elementar passou a significar introdutório, ou simples, e a caracterizar essencialmente as obras voltadas para o ensino. Ainda hoje a Matemática é, muitas vezes, tanto no Brasil como no exterior, tratada no ensino básico como uma espécie de introdução que nunca transcende a si mesma. Os autores também reuniram no livro os resultados de algumas intervenções de campo, como discussões que promoveram com crianças e seus professores acerca da influência da memória comunitária no aprendizado da Matemática e levantamento sobre a importância da oralidade para a transmissão de conhecimentos de Aritmética e Geometria.

Studies using bio(muco)adhesive drug delivery systems have recently gained great interest, which can promote drug targeting and more specific contact of the drug delivery system with the various absorptive membranes of the body. This technological platform associated with nanotechnology offers potential for controlling drug delivery; therefore, they are excellent strategies to increase the bioavailability of drugs. The objective of this work was to study nanotechnology-based polymeric bio(muco)adhesive platforms for controlling drug delivery, highlighting their properties, how the bio(muco)adhesion can be measured and their potential applications for different routes of administration.

Digital repositories are currently being used by education and research institutions in Brazil as an alternative for propagating scientific and academic results, mainly to reach institutional memory and visibility. However, the way these results are presented may influence their use, affecting user-system interaction through the interface components. Thus, it is possible to state that an unique digital information environment can offer different ways of visual presentation, customizing informational and visual components for specific users communities. In this context, tools are being developed as a resource to make access and use of information easier, and to increase the usability of digital informational environments. One of these tools, Manakin, is presented in this paper, as well as its integration with the DSpace platform, in order to enable multiple visual presentations, stressing the importance of the differentiation and direction of interfaces by a single repository to the various knowledge fields. So, results and examples of repositories with multiple visual presentations are introduced, to facilitate the use of the presented tool, as well as to reinforce the importance of a differentiated visual identity by areas of knowledge in a single repository, by means of literary and exploratory analysis.

This article aims to analyze literacy teachers’ conception of language from the classroom scenes that demonstrate the teaching of the act of reading. For the realization of the objective was carried out research in education like ethnography with two teachers in the 2nd year of elementary school a school of the Municipal located in the city of Sao Luis in Maranhão State, whose main instrument for data generation was participant observation. Also, I was guided by microgenetic analysis in order to focus our gaze to the particular aspect of the situation with attention to the “clues” to extract meaningful data. Authors such as Mikhail Bakhtin (1995, 2003) and scholars in the fi eld of reading, Josette Jolibert (1994), Elie Bajard (2007), among others, were considered core to grasp the meaning assigned by the subjects to teaching the act of reading. The fi ndings reveal that the design language of the teacher infl uences the direction of your practice, determining how to teach reading.

The global growing demand for food coupled with the direction of eating habits for products of animal origin, become even more necessary the search for alternatives to increase production. In this way, improve animal performance through the use of ionophores has become an effective measure to increase production and profitability of farms. Among the ionophores, monensin is the best known so far, as to their effect on the pattern of rumen fermentation and its consequences on animal production, especially by improving the quality or quantity of nutrients available for absorption through the gastrointestinal tract and consequently the performance of ruminants

Pipelines are linear construction that intersect several environments, requiring integration of environmental and technical aspects in its various elaboration steps. Environmental impact assessment if made to integrate the environmental information to enable environmental characterization, possibility identify previously fragilities of environment what contributes to the safety forecast of the significant impacts. These studies shall consider superimpose of the elements and the worsening of critical situations that already exists. In this way, meet and analyse informations about the environmental impact assessment, constructive aspects related to pipelines transport and get environmental impact studies of the case studies, providing the student a critical vision for the discussion of the apropiate balance between description and analysis, methodological rigour and the interface between construction and the environmente with inserts. Performing the critical analysis of methodologies and applied criteria for the environmental diagnosis and impact identification, search improve the methodologies for elaboration of environmental impact studies for linear construction, particulary pipelines, minin conflicts and giving security for the license process. Await provide subsidy to direction data collection, for choosing environmental indicator and for the prognosis and indentification of impacts.
