Advances in smart grids - benefits on sharing background experiences from Portugal, Central Europe and Brazil

This paper presents ELECON - Electricity Consumption Analysis to Promote Energy Efficiency Considering Demand Response and Non-technical Losses, an international research project that involves European and Brazilian partners. ELECON focuses on energy efficiency increasing through consumer´s active participation which is a key area for Europe and Brazil cooperation. The project aims at significantly contributing towards the successful implementation of smart grids, focussing on the use of new methods that allow the efficient use of distributed energy resources, namely distributed generation, storage and demand response. ELECON puts together researchers from seven European and Brazilian partners, with consolidated research background and evidencing complementary competences. ELECON involves institutions of 3 European countries (Portugal, Germany, and France) and 4 Brazilian institutions. The complementary background and experience of the European and Brazilian partners is of main relevance to ensure the capacities required to achieve the proposed goals. In fact, the European Union (EU) and Brazil have very different resources and approaches in what concerns this area. Having huge hydro and fossil resources, Brazil has not been putting emphasis on distributed renewable based electricity generation. On the contrary, EU has been doing huge investments in this area, taking into account environmental concerns and also the economic EU external dependence dictated by huge requirements of energy related products imports. Sharing these different backgrounds allows the project team to propose new methodologies able to efficiently address the new challenges of smart grids.

The role of functional polymorphisms in immune response genes as biomarkers of BCG Immunotherapy outcome in bladder cancer: Establishment of a predictive profile in a Southern Europe population

OBJECTIVE: To evaluate the predictive value of genetic polymorphisms in the context of BCG immunotherapy outcome and create a predictive profile that may allow discriminating the risk of recurrence. MATERIAL AND METHODS: In a dataset of 204 patients treated with BCG, we evaluate 42 genetic polymorphisms in 38 genes involved in the BCG mechanism of action, using Sequenom MassARRAY technology. Stepwise multivariate Cox Regression was used for data mining. RESULTS: In agreement with previous studies we observed that gender, age, tumor multiplicity and treatment scheme were associated with BCG failure. Using stepwise multivariate Cox Regression analysis we propose the first predictive profile of BCG immunotherapy outcome and a risk score based on polymorphisms in immune system molecules (SNPs in TNFA-1031T/C (rs1799964), IL2RA rs2104286 T/C, IL17A-197G/A (rs2275913), IL17RA-809A/G (rs4819554), IL18R1 rs3771171 T/C, ICAM1 K469E (rs5498), FASL-844T/C (rs763110) and TRAILR1-397T/G (rs79037040) in association with clinicopathological variables. This risk score allows the categorization of patients into risk groups: patients within the Low Risk group have a 90% chance of successful treatment, whereas patients in the High Risk group present 75% chance of recurrence after BCG treatment. CONCLUSION: We have established the first predictive score of BCG immunotherapy outcome combining clinicopathological characteristics and a panel of genetic polymorphisms. Further studies using an independent cohort are warranted. Moreover, the inclusion of other biomarkers may help to improve the proposed model.

Characterization of the portuguese SSS into the Europe: a contribution

Nowadays, Short Sea Shipping (SSS) is an essential part in European multi-modal transport system, representing approximately thirty-seven per cent of intra-Community transactions in tonnes per kilometre (tkm). Since 2001, the European Shortsea Network (ESN) in partnership with the short-sea Promotion Centres (SPC) of each Member State of the European Union (EU) have managed to make significant progress in the promotion and development of this mode of transport. This paper aims to assess and analyse the SSS of containerised goods in Portugal and its articulation with other EU routes and also other transport modes. The current SSS infrastructure, how the sector is organized, as well as the future perspectives for the sector are also analysed for the case of Portugal. The analyses are based on a survey that was carried out on the logistics operators, navigation agents, freight forwarders, and the leading imports and exports manufacturers in Portugal.

Accounting accruals and information asymmetry in Europe

We investigate whether the positive relation between accounting accruals and information asymmetry documented for U.S. stock markets also holds for European markets, considered as a whole and at the country level. This research is relevant because this relation is likely to be affected by differences in accounting standards used by companies for financial reporting, in the traditional use of the banking system or capital markets for firm financing, in legal systems and cultural environment. We find that in European stock markets discretionary accruals are positively related with the Corwin and Schultz high-low spread estimator used as a proxy for information asymmetry. Our results suggest that the earnings management component of accruals outweighs the informational component, but the significance of the relation varies across countries. Further, such association tends to be stronger for firms with the highest levels of positive discretionary accruals. Consistent with the evidence provided by the authors, our results also suggest that the high-low spread estimator is more efficient than the closing bid-ask spread when analysing the impact of information quality on information asymmetry.

HRM higher education in Europe

Higher education has earned in the recent years an increasing attention in Europe. European Higher Education Area (EHEA) is being developed, a three-cycle qualifications structure is formally in place, the principles of quality assurance are agreed, and a range of mobility instruments is being created. A European Qualifications Framework (EQF) is established (2008), and national qualifications frameworks in Europe should be all be published this year. In the HRM field, higher education is remaining largely unexamined. It is undertheorised and with lack of empirical research, especially if we consider the European reality. With the exception of Brewster et al. (2000) and Boxall et al. (2007), all the research published on the specific HRM higher education field seems to be American (Barber, 1999; Chadwick, 2005; Hayton et al.,2005; Kaufman, 1996, 1999; Langbert, 2005, 2000; Sincoff & Owen, 2004; Van Eyden et al., 1997; Wimbush 2008). This study analyses HRM higher education in Europe with the aim to identify the current trends of European HRM academic qualifications system. In order to provide strategic indicators on the subject, research was carried out in 14 European countries. The sample was constituted by the three cycles defined in Bergen (bachelor, master and PhD) and the primary information source was the Portal on Learning Opportunities throughout the European Space promoted by the European Commission (PLOTEUS). Within a qualitative methodology, qualifications’ structures, approaches, and competencies are explored as main analytical categories.

Otimização do Funcionamento de Caldeiras Aquatubulares em Indústria de Processo Químico

O presente trabalho centrou-se na otimização do rendimento térmico de duas caldeiras aquatubulares da empresa RAR- Refinaria de Açúcar Reunidas, com a finalidade de identificar onde ocorrem perdas de energia e, desta forma, propor soluções para a sua minimização. Para tal, realizaram-se ensaios em duas caldeiras da empresa providas de queimadores mistos, ou seja podem operar com fuelóleo e gás natural, tanto individualmente, como simultaneamente, sendo que para a realização dos ensaios apenas se utilizou o fuelóleo devido ao seu menor custo. Na caldeira designada por 1 realizaram-se ensaios para os caudais de 300, 500, 800, 1000, 1200, 1400 e 1600 kg/h de fuelóleo. A gama de rendimentos térmicos obtida foi entre 88,3 e 91,2%. Na caldeira designada por 3, efetuaram-se ensaios para os caudais de fuelóleo de 300, 500, 700, 900, 1000, 1200, 1400, 1500 e 1800 kg/h e os rendimentos térmicos obtidos foram entre 85,2 e 88,0%. Em ambas as caldeiras e para caudais baixos verificou-se que a quantidade de ar introduzida no processo de combustão era superior à necessária, conduzindo a uma diminuição dos valores de rendimento térmico. Para 500 kg/h de fuelóleo, por exemplo, a quantidade de ar utilizada foi cerca de duas vezes superiores ao valor estequiométrico. Tendo em conta estes factos, foi proposto ao gestor de energia a implementação de uma nova relação de ar/combustível vs caudal de combustível no sistema de controlo das referidas caldeiras. Após alguns testes (excluindo 300 kg/h de fuelóleo devido a questões de operação), considerou-se como caudal mínimo de operação os 500 Kg/h de fuelóleo nas respetivas caldeiras 1 e 3. Verificou-se que os rendimentos térmicos aumentaram, no caso da caldeira 1, para valores entre os 90,1 e 91,3% e, na caldeira 3, para valores entre 89,0 e 90,9%. Por fim, efetuou-se uma breve análise económica com o intuito de se avaliar e quantificar o que a empresa pode poupar com esta medida. O lucro anual pode oscilar entre 14.400 e 62.640€ ou 104.400 e 136.800€, para as caldeiras 1 e 3, respetivamente.
