Energy consumption and energy efficiency in olive oil mills: case studies in Portugal and Spain in the frame of TESLA project

TESLA project (Transfering Energy Save Laid on Agroindustry) financed by the European Commission, had the main goals of evaluating the energy consumption and to identify the best available practices to improve energy efficiency in key agro-food sectors, such as the olive oil mills. A general analysis of energy consumptions allowed identifying the partition between electrical and thermal energy (approximately 50%) and the production processes responsible for the higher energy consumptions, as being the in the mill and paste preparation and the phases separation. Some measures for reducing energy waste and for improving energy efficiency were identified and the impact was evaluated by using the TESLA tool developed by Circe and available at the TESLA website.

How to enhance Geobotany in the frame of the renewed Biological Sciences?

In recent decades the importance of structuring sciences such as botany or phytosociology faced a declining attention from the scientific community. This was accompanied by a growing interest in theoretical ecology. For such scenario greatly contributed an hypothetical exhaustion of research topics in these areas, but especially the introduction of new technologies that have provided powerful tools for data analysis. This allowed, for example, to make predictions about the impacts of climate change on species and plant communities and the consequent recognition of theoretical ecology, as one of the most prestigious pieces of current biological sciences. However, theoretical ecology has been facing serious knoledge gaps that greatly compromise their results, putting again the spotligth on structuring sciences. For example there are enourmous gaps in knowledge and data on dispersal, species and communities chorology and abundace, as well as in biological interactions. These data is essential, since they will determine ecological behavior of species. Its omission always limits the understanding and proper execution of the models generated by theoretical ecology. In this conference we will present a review on the gaps in knowledge and data in flora and vegetation fields in order to identify situations where geobotanical knowledge can make their major contribution. Furthermore, we will emphasize the need to reformulate objectives in geobotanical sciences in order to give it the deserved scientific recognition, considering the relationship between different scientific knowledges.

A motivação dos docentes no ensino superior face ao processo de Bolonha: um estudo de caso

Este trabalho pretende estudar a motivação dos docentes da licenciatura de radioterapia da Escola Superior de Tecnologias da Saúde de Lisboa, face ao processo de Bolonha. Realizou-se um enquadramento teórico dos conceitos base, como motivação e processo de Bolonha. O estudo foi definido como um estudo de caso, com uma amostra de 3 elementos. Aplicou-se três entrevistas a cada um dos entrevistados, denominadas por entrevista, entrevista reflexiva e entrevista reflexiva aprofundada. Para a análise dos dados utilizou-se um software de análise de conteúdo -AQUAD 6.0. Os resultados são apresentados em forma de tabelas e segmentos de texto extraídos do software. Na discussão dos resultados verifica-se que de uma forma geral os resultados vão ao encontro da literatura existente e nas considerações finais respondem-se às questões de investigação inicialmente realizadas, mas também são apresentadas as limitações ao estudo, bem como futuras investigações. ABSTRACT: lt is intended with this work to study the motivation of the radiotherapy graduated professors of the Higher School of Health Technology of Lisbon, regarding the Bologna process. lt was performed a theoretical frame of reference of the basic concepts such as motivation and the Bologna Process. The study was defined as a case study, with a sample of three elements. Three interviews were performed to each interviewed person, defined as interview, reflexive interview and deepened reflexive interview. For the data analysis it was used a content analysis software - AQUAD 6.0. The results are presented in table form and with text sectors obtained from the software. ln the discussion of the results one comes to the conclusion that, in general, they match the available literary writings and in the final reflexions it is answered to the investigation questions initially asked but also presented the study limitations as well as future investigations.
