Autonomy in English language learning: a case study

The main goal of this study was to analyse the development of a pedagogy for autonomy tuned to the current situation in which Higher Education finds itself, namely of implementation of the Bologna Process in Europe, and in particular at the Escola Superior Agrária of the Polytechnic School at Coimbra. For this purpose new course units were created, new descriptors written, new materials developed and new methodologies tried. A case study was undertaken to observe and analyse the changes the institution was undergoing and to assess the impact of the new methodologies, particularly regarding the development of student autonomy. The target population for this study were the first year students on the Biotechnology degree in the year 2007/2008, to whom a battery of tests were applied, namely proficiency tests, belief tests, metacognitive tests, as well as methods of ethnographic research. The study relied on the European Framework of Reference for Languages and the European Language Portfolio to establish recognised levels and competences, and employed the portfolio as its main tool for measuring student autonomy. This portfolio was simultaneously biographical and descriptive and was organised by the students in their own time. Great incentive was given to this independent work. The ethnographic component of the study was of significant importance being given to students learning histories and to the collection of students’ reflections. This component aimed in particular to allow students the opportunity to express their thoughts on the experience they underwent during 20 weeks. From the analysis of the data, a significant improvement in self-confidence and motivation for lifelong learning is observable in the development of multiple tasks. Regarding the students’ progression towards proficiency, this improvement is less clear, but the final results of educational success were generally of great relevance.

Reverse problem-based learning - a case study with a Braille machine

Engineering Education includes not only teaching theoretical fundamental concepts but also its verification during practical lessons in laboratories. The usual strategies to carry out this action are frequently based on Problem Based Learning, starting from a given state and proceeding forward to a target state. The possibility or the effectiveness of this procedure depends on previous states and if the present state was caused or resulted from earlier ones. This often happens in engineering education when the achieved results do not match the desired ones, e.g. when programming code is being developed or when the cause of the wrong behavior of an electronic circuit is being identified. It is thus important to also prepare students to proceed in the reverse way, i.e. given a start state generate the explanation or even the principles that underlie it. Later on, this sort of skills will be important. For instance, to a doctor making a patient?s story or to an engineer discovering the source of a malfunction. This learning methodology presents pedagogical advantages besides the enhanced preparation of students to their future work. The work presented on his document describes an automation project developed by a group of students in an engineering polytechnic school laboratory. The main objective was to improve the performance of a Braille machine. However, in a scenario of Reverse Problem-Based learning, students had first to discover and characterize the entire machine's function before being allowed (and being able) to propose a solution for the existing problem.

Henrique Novaes: técnica, território e cidade em uma trajetória profissional: Brasil, primeira metade do século XX

The career of civil engineer Henrique de Novaes, a remarkable figure in the academic, technical and political fields, demonstrates its extensive and relevant work across Brazil in the first half of the twentieth century. It covered from the design of water supply and sewage works, road and rail transport networks, works against drought in the Northeast, hydroelectric and harbor facilities to the urbanization planning and architectural projects, which displays a systematic and multiple production. City and territory conformed to his fields of verification, practical and above all, transformation. The search for understanding of the inclusion of a social actor in this process thus contributes to the specific analysis of the doings of Henrique de Novaes, who graduated at Polytechnic School of Rio de Janeiro in 1906. From a polymorphic activity in different scales, one tries to figure how, through academic education or professional practice, urban history in Brazil can be told or built. The introduction of technological innovations matched the purposes of planning and urban sprawl, as well as met the specifications of regulation and institutionalization of public infrastructure services at the time. The overall plans proposed by the engineer thought of the city as a whole, interconnected to the structural networks. At the same time, the knowledge of a larger physical scale the territory bounces back in the urban in a relationship of reciprocity and completeness. The objective research, therefore, tries to understand the roles played by Henrique de Novaes s works and academic education in the accomplishment of systematic modernization of Brazilian urban space and territory, recovering a little known historical figure by current historiography. It is proposed, as methodological axis, that the study of this professional career configures itself as an essential element for understanding the idea of progress embodied in the technical studies and proposals for improvements and sanitation nationwide in the first half of the twentieth century . The primary sources for the construction of this analysis were technical articles in journals of the period ( Clube de Engenharia , Viação e Revista Brasileira de Engenharia ), and technical reports, government messages, newspaper articles published at the time, autobiographical reports and the engineer s verbal communications with relatives. The work is structured in three chapters: "Biographical traces, academic education and 'technical and political' activities" illustrates the initiation into the technical, public and political environment; Chapter 2, "Technique and territory" outlines his network understanding through sanitation and transport services; Chapter 3 "Technique and City" describes the influence of polytechnics knowledge on the propositions of modernization of cities; Finally, "Final Thoughts: An Evaluation," presents an overview of the affiliations and practice of an engineer in the different scales, and its contribution to the modernization of Brazilian urban and territorial space

El conflictivo nacimiento de la Universid de São Paulo en la década de 1930

The creation of the University of São Paulo in the early 1930’s brought about arguments in the projects about its organization. The idea was to establish the Polytechnic School of São Paulo as the core of the future institution. However, the option adopted in 1934 allocated this position to the newly created Faculty of Philosophy, Science and Letters. This caused a strong reaction by both former professional schools that were incorporated into the university, above all the Polytechnic School. This article sets out to describe the conflicts between the Polytechnic School and the Faculty of Philosophy, Science and Letters during the tumultuous beginnings of the University of São Paulo.

Reducing Water and Chloride Penetration Through Silicate Treatments for Concrete as a Mean to Control Corrosion Kinetics

There are currently many types of protective materials for reinforced concrete structures and the influence of these materials in the chloride diffusion coefficient and water penetration still needs more research. The aim of this work is to analyze the contributions regarding the typical three surface concrete protection systems (coatings, linings and pore blockers) and discusses the results of three pore blockers (sodium silicate) tested in this work. To this end, certain tests were used: one involving permeability mechanism (low pressure-immersion absorption), one involving capillary water absorption, and the last, a migration test used to estimate the effective chloride diffusion coefficient in saturated condition. Results indicated reduction in chloride diffusion coefficients and capillary water absorption, therefore, restrictions to water penetration from external environmental. As a consequence, a reduction of the corrosion kinetics and a control of the chloride ingress are expected.

Numerical simulation of an ethanol turbulent spray flame with RANS and diffusion combustion model

A detailed numerical simulation of ethanol turbulent spray combustion on a rounded jet flame is pre- sented in this article. The focus is to propose a robust mathematical model with relatively low complexity sub- models to reproduce the main characteristics of the cou- pling between both phases, such as the turbulence modulation, turbulent droplets dissipation, and evaporative cooling effect. A RANS turbulent model is implemented. Special features of the model include an Eulerian– Lagrangian procedure under a fully two-way coupling and a modified flame sheet model with a joint mixture fraction– enthalpy b -PDF. Reasonable agreement between measured and computed mean profiles of temperature of the gas phase and droplet size distributions is achieved. Deviations found between measured and predicted mean velocity profiles are attributed to the turbulent combustion modeling adopted

Ensino de construção de edifícios: FAUUSP x EPUSP

O reconhecimento das competências e habilidades necessárias ao exercício profissional de arquitetos e engenheiros civis brasileiros é adquirido em decorrência das formações que lhes são oferecidas. No âmbito da construção de edifícios, pressupõe-se que ambos os profissionais recebem formação equivalente na medida em que os respectivos conselhos lhes atribuem iguais direitos e responsabilidades para exercê-la. Com o objetivo de investigar tal pressuposto, esse trabalho se propôs a examinar a formação oferecida nesse campo aos profissionais oriundos de duas das principais escolas do país: da Faculdade de Arquitetura e Urbanismo da USP (FAUUSP) e da Escola Politécnica da USP (EPUSP). Por meio de análise das estruturas curriculares, de depoimentos docentes coletados em entrevistas, materiais didáticos empregados em aulas, registros de aula de estudantes no decorrer do curso e de acompanhamento presencial em disciplinas que versam sobre o assunto, essa pesquisa revelou que as formações oferecidas pelas duas instituições são profundamente distintas. Na FAUUSP, constatou-se que a formação voltada à construção de edifícios corresponde à abordagem apenas introdutória dos assuntos, fornecida por meio de disciplinas desarticuladas entre si e em relação às demais disciplinas constantes da estrutura curricular. Na EPUSP, em oposição, o tema inserese em conjunto intimamente articulado de disciplinas, as quais fornecem ao estudante intensa fundamentação científica para discussão dos assuntos envolvidos. O trabalho, portanto, reforça a ideia, que vem de longa data, sobre a urgência em se rediscutir a formação oferecida ao estudante de arquitetura e urbanismo na FAUUSP, e principalmente nesse trabalho, no que se refere aos conteúdos de incumbência do Grupo de Disciplinas de Construção do Departamento de Tecnologia da Arquitetura da Escola.

Metodologia para a homologação dos equipamentos do Sistema Canal Azul da Carne - MHECAC.

Este trabalho de pesquisa apresenta a Metodologia para a Homologação dos Equipamentos do Sistema Canal Azul da Carne - MHECAC. Esta proposta de metodologia é complementar ao desenvolvimento do Sistema Canal Azul da Carne e tem o objetivo de apoiar o MAPA (Ministério da Agricultura, Pecuária e Abastecimento) no estabelecimento de um processo de verificação da conformidade de equipamentos, buscando garantir a interoperabilidade, o desempenho e a segurança de seus componentes de hardware. O Sistema Canal Azul é uma realização do MAPA em conjunto com o GAESI da Escola Politécnica da Universidade de São Paulo (EPUSP) e a iniciativa privada, e tem o objetivo de reduzir o tempo empregado nos processos de exportação de carnes no Brasil. A MHECAC baseia-se na estrutura de processo de avaliação de conformidade estabelecida pelo Sistema Brasileiro de Avaliação da Conformidade - SBAC e seus requisitos gerais podem ser aplicados à avaliação de conformidade de produtos em setores variados. No desenvolvimento da MHECAC foram aplicadas as principais referências técnicas e normativas correspondentes aos equipamentos que compõe a arquitetura do sistema Canal Azul. Além disto, foram definidos os modelos de homologação, auditoria e inspeção, os planos de amostragem, os requisitos mínimos e a metodologia de ensaio. A MHECAC subdivide-se em dois segmentos principais. O primeiro apresenta os requisitos gerais para o estabelecimento de sistemas de avaliação da conformidade e certificação de produtos, a aplicação destes requisitos não se limita ao Sistema Canal Azul, e o segundo apresenta requisitos específicos ao sistema estabelecido pelo MAPA. A aplicação da MHECAC favorece o tratamento isonômico de fornecedores e é um importante balizador para a seleção de equipamentos, pois permite a qualificação e a comparação de soluções, por meio de um embasamento técnico, pautado pela qualidade.

Controle cooperativo aplicado a sistemas de posicionamento dinâmico.

Hoje em dia com o crescente aumento da exploração de petróleo e gás em águas profundas, há um aumento na demanda por operações offshore envolvendo a cooperação entre unidades flutuantes. Tais operações requerem um alto nível de planejamento e coordenação, o que na maioria dos casos é feito com a troca de informação no nível de operação, com cada unidade flutuante comandada independentemente. Exemplos de operações deste tipo vão desde operações de alívio passando por operações de instalação de equipamento submarino, até operações de pesquisa envolvendo múltiplas unidades flutuantes dotadas de sistema de posicionamento dinâmico (DP). As vantagens do controle cooperativo surgem com a redução do erro da distância relativa durante a manutenção do posicionamento ou durante a execução de manobras de posicionamento conjuntas. No presente trabalho, os conceitos de controle de consenso são aplicados de forma combinada com o sistema DP de cada navio. A influência dos ganhos do controlador cooperativo no sistema como um todo será discutida, utilizando-se técnicas de análise da resposta em frequência. Simulações completas no domínio do tempo e experimentos usando modelos em escala serão utilizados para se demonstrar o funcionamento do controle cooperativo. Todas as simulações serão conduzidas no simulador Dynasim e os ensaios experimentais no tanque de provas da Engenharia Naval da Escola Politécnica da Universidade de São Paulo. Além disso, serão feitas comparações entre os experimentos em tanque de provas e simulações numéricas equivalentes, demonstrando-se a validade dos ensaios numéricos. Será também demonstrado que os requisitos de projetos adotados são atendidos pelos ensaios em tanque de provas. .
