LSP communication in a digital age: the outcomes of teaching and learning in tertiary education

This paper discusses the changes brought by the communication revolution in teaching and learning in the scope of LSP. Its aim is to provide an insight on how teaching which was bi-dimensional, turned into a multidimensional system, gathering other complementary resources that have transformed, in a incredibly short time, the ways we receive share and store information, for instance as professionals, and keep in touch with our peers. The increasing rise of electronic publications, the incredible boom of social and professional networks, search engines, blogs, list servs, forums, e-mail blasts, Facebook pages, YouTube contents, Tweets and Apps, have twisted the way information is conveyed. Classes ceased to be predictable and have been empowered by digital platforms, innumerous and different data repositories (TILDE, IATE, LINGUEE, and so many other terminological data banks) that have definitely transformed the academic world in general and tertiary education in particular. There is a bulk of information to be digested by students, who are no longer passive but instead responsible and active for their academic outcomes. The question is whether they possess the tools to select only what is accurate and important for a certain subject or assignment, due to that overflow? Due to the reduction of the number of course years in most degrees, after the implementation of Bologna and the shrinking of the curricula contents, have students the possibility of developing critical thinking? Both teaching and learning rely on digital resources to improve the speed of the spreading of knowledge. But have those changes been effective to promote really communication? Furthermore, with the increasing Apps that have already been developed and will continue to appear for learning foreign languages, for translation among others, will the students feel the need of learning them once they have those Apps. These are some the questions we would like to discuss in our paper.

Voltammetric oxidation of drugs of abuse I. Morphine and metabolites

A detailed study of the electrochemical oxidative behavior of morphine in aqueous solution is reported. Through the synthesis of several metabolites and derivatives, pseudomorphine, morphine N-oxide, normorphine, dihydromorphine and 2-(N,N-dimethylaminomethyl)morphine, and their voltammetric study it was possible to identify the oxidation peaks for morphine. The anodic waves are related with the oxidation of phenolic and tertiary amine groups. It is also possible to verify that a poorly defined peak observable during morphine oxidation is not a consequence of further oxidation of pseudomorphine but due to formation of a dimer during phenolic group oxidation. The results obtained and especially those regarding the formation of a new polymer based on a C O coupling could be useful for clarifying the discoloration phenomenon occurring during storage of morphine solutions as well as leading to a better understanding of its oxidative metabolic pathways.

Voltammetric oxidation of drugs of abuse II. Codeine and metabolites

The oxidation of codeine on glassy carbon electrodes has been studied in detail using differential pulse voltammetry. The results obtained using a glassy carbon electrode clearly show a much more complex oxidation mechanism than that previously reported when platinum and gold electrodes were used. To clarify the codeine oxidative profile, several metabolites and analogues of this alkaloid, codeine N-oxide, norcodeine, dihydrocodeine, acetylcodeine and 6- chlorodesoxycodeine, were synthesized and studied. It was deduced that the anodic waves observed in codeine oxidation are related to the presence of methoxy, hydroxy and tertiary amine groups. Due to the similarity of potentials at which these oxidative processes take place, at some pHs an overlap of peaks occurs and only one anodic wave is observed.

Oxidative behaviour of apomorphine and its metabolites

The metabolism of apomorphine is quite complex due to interactions with proteins and other tissue components that affect its pharmacokinetic profile. The electrochemical oxidation mechanism of apomorphine and of some synthesised apomorphine derivatives was studied. It was found to be related to the reaction of o-diphenol and tertiary amine groups and strongly dependent on pH.

Estações de tratamento de águas residuais: conceitos e dimensionamento

O presente relatório é o corolário do Estágio Curricular que a autora efetuou, durante o segundo semestre do ano letivo de 2014/2015 na SBS – Engenharia Civil, Hidráulica e Ambiente, Lda. Nesta empresa a autora foi integrada na equipa técnica que elaborou um Projeto de Execução para uma Estação de Tratamento de Águas Residuais que irá ser construída em Montemor-o-Novo, tendo-lhe sido atribuídas as seguintes tarefas principais: i) estudo de ferramentas de dimensionamento de ETAR; e ii) estudo dos processos de tratamento de águas residuais a instalar. O tratamento de águas residuais não é matéria que conste do atual Plano de Estudos do Mestrado em Engenharia Civil do ISEP. Este facto, associado à premente necessidade de dar resposta às expectativas da Entidade Acolhedora, obrigou a autora a um esforço de aprendizagem significativo. Nesta fase foi executada uma aprofundada pesquisa bibliográfica que permitiu à autora obter o nível de conhecimentos teóricos necessário para a plena integração na Equipa de Projeto. Já integrada na Equipa de Projeto o primeiro trabalho desenvolvido pela autora foi a análise detalhada do Caderno de Encargos e da respetiva Nota Técnica. Seguidamente a autora participou em todas as fases do Projeto tendo, por isso, colaborado na análise do Estudo Geotécnico, no dimensionamento dos órgãos da ETAR, no cálculo do perfil hidráulico, na definição de formas (plantas e cortes) dos órgãos, na elaboração da Lista de Equipamentos e do Mapa de Quantidades e, por último, na elaboração da Memória Descritiva e Justificativa do Processo de Tratamento e Equipamentos. O Caso Prático incluído no presente documento é, em larga medida, o corolário do processo de aprendizagem de que a autora beneficiou no decorrer do Estágio Curricular. Grande parte das tarefas que a autora executou ao longo da elaboração do projeto relacionaram-se com o dimensionamento dos órgãos da ETAR e com os respetivos cálculos hidráulicos. Os conhecimentos teórico-práticos desta forma adquiridos foram reunidos num conjunto de ferramentas, maioritariamente folhas de cálculo, que se verificou serem úteis nos processos de dimensionamento e de teste de soluções alternativas. É parte integrante deste relatório um capítulo no qual é feita uma detalhada apresentação dos conceitos teóricos subjacentes ao Projeto de ETAR. Este capítulo reflete o estudo que a autora teve necessidade de efetuar antes de se sentir capaz de integrar a Equipa de Projeto.

Kitchen robot prod. line development. Proj. of Bowden cables cutting and thermal forming machine.

This document presents particular description of work done during student’s internship in PR Metal company realized as ERASMUS PROJECT at ISEP. All information including company’s description and its structure, overview of the problems and analyzed cases, all stages of projects from concept to conclusion can be found here. Description of work done during the internship is divided here into two pieces. First part concerns one activities of the company which is robotic chefs (kitchen robot) production line. Work, that was done for development of this line involved several tasks, among them: creating a single-worker montage station for screwing robots housing’s parts, improve security system for laser welding chamber, what particularly consists in designing automatically closing door system with special surface, that protects against destructive action of laser beam, test station for examination of durability of heating connectors, solving problem with rotors vibrations. Second part tells about main task, realized in second half of internship and stands a complete description of machine development and design. The machine is a part of car handle latch cable production line and its tasks are: cutting cable to required length and hot-forming plastic cover for further assembly needs.
