A democracia na União Europeia em crise : o caso da Grécia (2009-2015)

A União Europeia encontra-se numa encruzilhada provocada por uma crise multifacetada (económica, financeira, política e social), com início em 2007/2008 com a pior crise económica desde a década de 30 na Europa. A crise revelou problemas com diversas origens e consequências, e cujo desfecho se afigura ainda hoje imprevisível, constituindo um incontornável desafio ao futuro da União Europeia. Além da crise económica e da crise das dívidas soberanas, verifica-se uma preocupante crise da democracia europeia, a somar à já amplamente debatida questão do défice democrático. A crise e as respostas à mesma conduziram à imposição de políticas e medidas de austeridade, que acarretaram significativas interferências atípicas no normal funcionamento da democracia, desde logo pela adoção de procedimentos e o surgimento de novos atores na gestão da crise à margem do jogo democrático. Em Outubro de 2009, o governo grego reconhece a situação de insustentabilidade financeira do país, colocando em suspense toda a zona euro, sendo o primeiro Estado membro a recorrer a assistência financeira externa sob severas condições e com impactos fortemente negativos no seu Estado de bem-estar social. Pretendemos saber e compreender o estado da democracia na União Europeia no contexto da crise, a partir do estudo de caso sobre a democracia grega no contexto da crise, delimitado ao período compreendido entre 2009 e 2015. Com o mesmo objetivo será feita uma análise do apoio dos Cidadãos gregos à democracia, da sua satisfação com o funcionamento da democracia, da sua confiança nas instituições e participação nas eleições, numa perspetiva diacrónica, ao nível da União Europeia e do Estado Grego.The European Union is at a crossroad due to a multifaceted crisis (economic, financial, political and social), which started in 2007/2008 with the worst economic crisis since the 1930s in Europe. The crisis has revealed problems with different origins and consequences, and whose outcome is still unpredictable today, becoming an inevitable challenge to the future of the European Union. Apart from the economic crisis and the sovereign debt crisis, there is an alarming crisis of European democracy, together with the already widely debated issue of the democratic deficit. The crisis and its responses have led to the imposition of austerity policies and measures, which caused significant atypical interference in the normal functioning of democracy, from the adoption of procedures and the emergence of new actors in crisis management, outside the democratic game. In October 2009, the Greek government acknowledged the financially unsustainable situation of its country, keeping the whole euro area in suspense. It was the first member state to turn to external financial assistance under severe conditions with heavily and negative impact on its social welfare state. We want to know and understand the state of democracy in the European Union in the context of the crisis, starting from the case study on Greek democracy in the context of the crisis, delimited between 2009 and 2015. At the same time we will analyse the Greek citizens’ support to the democracy, their satisfaction with the functioning of democracy, their confidence in the institutions and participation in the elections, with a diachronic perspective at the level concerning the European Union and the Greek State

Design, Sustainability Analysis and Multiobjective Optimisation of Ethanol Production via Syngas Fermentation

Ethanol production from non-edible feedstock has received significant attention over the past two decades. The utilisation of agricultural residues within the biorefinery concept can positively contribute to the renewable production of fuels. To this end, this study proposes the utilisation of bagasse in a hybrid conversion route for ethanol production. The main steps of the process are the gasification of the raw material followed by syngas fermentation to ethanol. Aspen plus was utilised to rigorously design the biorefinery coupled with Matlab to perform process optimisation. Based on the simulations, ethanol can be produced at a rate of 283 L per dry tonne of bagasse, achieving energy efficiency of 43% and according to the environmental analysis, is associated with low CO2 emissions. The conduction of a typical discounted cash flow analysis resulted in a minimum ethanol selling price of 0.69 $ L−1. The study concludes with multiobjective optimisation setting as objective functions the conflictive concepts of total investment costs and exergy efficiency. The total cost rate of the system is minimised whereas the exergy efficiency is maximised by using a genetic algorithm. This way, various process configurations and trade-offs between the investigated criteria were analysed for the proposed biorefinery system

Pregled znanstvenih napredaka u učinskoj elektronici usmjerenih ka osiguravanju efikasnog rada i dužeg životnog vijeka PEMgorivih ćelija

This article focuses on the main issues that affect the lifetime and performance of proton-exchange membrane fuel cells. The short lifespans of these fuel cells represent a barrier to their massive commercialization and usage in mobile and stationary applications. As fuel cell is a very complex system, a lot of knowledge of different areas is required, such as chemistry, electricity and mechanics, in order to completely understand its operation and all the problems that can occur during it. It is for this reason that an interdisciplinary approach needs to be taken when designing fuel-cell energy systems. This paper focuses on identifying and solving those issues that negatively affect the lifetime and performance of fuel cells. It is hoped that this article would be a valuable aid for power electronics’ researchers and engineers for better understanding the presented issues and a useful guide for solving them with the use of proper power electronic-devices. Initially, the basic operation and structure of a proton-exchange membrane fuel cell is explained. Three main issues that can occur during operation of a mobile or stationary fuel cell energy system are pointed out and discussed in details, on the basis of the state-of-the-art on fuel cell technology. These issues are poor water management, reactant gas starvation and fuel cell current ripple. This article provides answers as to why they occur, how they affect the fuel cell, how they can be mitigated, and what are the future trends within this research field.Članak se osvrće na ključna pitanja koja utječu na vrijeme rada i performanse gorivih ćelija s polimernom membranom kao elektrolitom. Kratak životni vijek gorivih ćelija takve vrste prepreka je njihovoj komercijalizaciji i masovnoj upotrebi u mobilnim i stacionarnim stanicama. Budući da su gorive ćelije komplicirani sustavi potrebno je znanje iz raznih područja kemije, elektrotehnike i mehanike da bi se u potpunosti mogao razumjeti njihov način rada i problemi koji se događaju. Upravo je zbog toga multidisciplinarni pristup nužnost pri razvoju sustava koji koriste gorive ćelije. Ovaj je članak usmjeren prema identifikaciji i rješavanju onih problema koji negativno utječu na životni vijek i performanse gorivih ćelija. Autori se nadaju da će se članak pokazati kao korisna pomoć i vodič istraživačima i inženjerima u domeni učinske elektronike pri susretu s navedenim problemima. Objašnjen je način rada i struktura gorive ćelije s polimernom membranom kao elektrolitom. Izložena su, i diskutirana do u detalje, tri glavna problema sa stajališta trenutačnih spoznaja u području učinske elektronike. Ti problemi su: loše upravljanje vodom, nestanak reaktantnog plina i strujni trzaji u gorivim ćelijama. Objašnjeno je zašto se ovi problemi događaju, kako utječu na gorivu ćeliju, kako ih se može spriječiti i koje su buduće perspektive istraživanja
