Robust Solutions of MultiObjective Linear Semi-Infinite Programs under Constraint Data Uncertainty

The multiobjective optimization model studied in this paper deals with simultaneous minimization of finitely many linear functions subject to an arbitrary number of uncertain linear constraints. We first provide a radius of robust feasibility guaranteeing the feasibility of the robust counterpart under affine data parametrization. We then establish dual characterizations of robust solutions of our model that are immunized against data uncertainty by way of characterizing corresponding solutions of robust counterpart of the model. Consequently, we present robust duality theorems relating the value of the robust model with the corresponding value of its dual problem.

Effect of the surface chemical groups of activated carbons on their surface adsorptivity to aromatic adsorbates based on π-π interactions

Three activated carbons with different surface chemical groups were used to analyse the influence of these groups on their adsorption capacities towards aromatic-type molecules whose adsorption is based on π-π interactions with surface arene centres. The three activated carbons studied were a low-functionalized carbon (Merck), an oxygen-rich carbon obtained by HNO3 oxidation of Merck, and a nitrogen-rich carbon also prepared from Merck by mild HNO3 oxidation followed by treatment with a dicyanodiamide/dimethyl formamide mixture at 300 °C. The nature of the surface chemical groups of the three activated carbons was investigated by both physical and chemical techniques (TPD, XPS, Boehm analysis and pH potentiometric titration). A systematic study of the adsorptions of a series of analogous aromatic adsorbates on the three activated carbons was carried out to study the adsorption mechanisms. In all cases the adsorption mechanism is based on π-π interactions between the aromatic moiety of the adsorbates and the arene centres of the graphite sheets. The differences in the normalized adsorption capacities of the adsorbents for a set of adsorbates indicate that the π-donor or π-withdrawing character of the functional groups have a clear influence on the basicity of the arene centres.

EEAS 2.0: Recommendations for the amendment of Council Decision 2010/427/EU on the European External Action Service. CEPS Special Report No. 78, 13 November 2013

This Special Report offers recommendations for the amendment of the Council Decision 2010/427/EU establishing the organisation and functioning of the European External Action Service. Its purpose is to contribute, in practical legal terms, to the ongoing review of the Decision in 2013, as well as to the possible discussion on its revision that may take place in 2014. In particular, it sheds light on possible adjustments in the application of the Decision ‘à droit constant’, but also suggests potential alteration of its formulation.

EEAS 2.0: A legal commentary on Council Decision 2010/427/EU establishing the organisation and functioning of the European External Action Service. CEPS Paperbacks. February 2013

This short and user-friendly legal commentary on the 2010 Council Decision establishing the organisation and functioning of the EEAS is the first of its kind. It is intended to inform those involved in the review process and to serve as a reference document for practitioners and analysts dealing with the EEAS. Rather than an elaborate doctrinal piece, this legal commentary is a textual and contextual analysis of each article that takes account of i) other relevant legal provisions (primary, secondary, international); ii) the process leading to the adoption of the 2010 Council Decision; iii) the preamble of the Council Decision and iv) insofar as it is possible at this stage, early implementation. Wherever relevant, cross-references to other provisions of the Council Decision have been made so as to tie in the different commentaries and ensure overall consistency.

The European Court of Justice blocks the EU’s accession to the ECHR. CEPS Commentary, 8 January 2015

The goal of accession to the European Convention of Human Rights (ECHR) is to place the EU under the external oversight of the specialised court in Strasbourg. But in its Opinion of 18 December 2014 the Luxembourg-based European Court of Justice ruled that the draft accession agreement is not compatible with the EU treaties. In this commentary the authors argue that this would force EU member states to renegotiate the terms of accession to the ECHR. But meeting the demands made by the Court of Justice will prove to be very difficult.

The Legal Status and Influence of Decisions of International Organizations and other Bodies in the European Union. College of Europe Research Paper in Law 01/2014

Introduction. The European Union’s external action is not only defined by its influence on international developments, but also by its ability and the need to respond to those developments. While traditionally many have stressed the EU’s ‘autonomy’, over the years its ‘dependence’ on global developments has become more clear.2 International law has continued to play a key role in, not only in the EU’s external relations, but also in the Union’s own legal order.3 The purpose of this paper is not to assess the role or performance of the EU in international institutions.4 Rather it purports to reverse the picture and focus on a somewhat under-researched topic: the legal status of decisions of international organizations in the EU’s legal order.5 While parts of the status of these decisions relate to the status of international agreements and international customary law, it can be argued that decisions of international organizations and other international bodies form a distinct category. In fact, it has been observed that “this phenomenon has added a new layer of complexity to the already complex law of external relations of the European Union”.6 Emerging questions relate to the possible difference between decisions of international organizations of which the EU is a member (such as the FAO) and decisions of organizations where it is not (irrespective of existing competences in that area – such as in the ILO). Questions also relate to the hierarchical status of these decisions in the EU’s legal order and to the possibility of them being invoked in direct or indirect actions before the Court of Justice. This contribution takes a broad perspective on decisions of international organizations by including decisions taken in other international institutions which do not necessarily comply with the standard definition of international organizations,7 be it bodies set-up by multilateral conventions or informal (transnational / regulatory) bodies. Some of these bodies are relatively close to the EU (such as the Councils established by Association Agreements – see further Section 5 below); others operate at a certain distance. Limiting the analysis to formal international organizations will not do justice to the manifold relationships between the European Union and various international bodies and to the effects of the norms produced by these bodies. The term ‘international decisions’ is therefore used to refer to any normative output of international institutional arrangements.

As bolas paradas no futebol jovem – A opinião dos treinadores

As bolas paradas têm ganho importância no futebol nas últimas décadas devido à sua influência no resultado final dos jogos. No entanto no futebol jovem ainda são poucos os estudos neste âmbito. O objetivo deste estudo foi auscultar a opinião dos treinadores acerca da importância das bolas paradas no futebol jovem, nomeadamente as diferenças relativamente ao futebol profissional, os exercícios utilizados no treino, a importância do lado estratégico e como potenciar o aparecimento de especialistas nestes lances. Foram entrevistados seis treinadores com experiência na primeira liga portuguesa de futebol, tendo sido utilizada a entrevista semi-estruturada como instrumento de recolha de dados. A análise e interpretação do conteúdo das entrevistas permitiu identificar que os treinadores consideram que o treino destes lances no futebol jovem deve ter características diferentes do futebol profissional, que os exercícios de treino no futebol jovem devam ser direcionados para a aprendizagem do jogo e dos seus princípios. Quanto ao lado estratégico indicaram que é mais relevante nos escalões mais avançados e nas competições nacionais. Para a potenciação do talento existe a necessidade de maior volume de treino destes lances específicos e também treino individual.

Aproveitamento de subproduto de maçã da indústria agroalimentar

Neste trabalho foi estudado um subproduto derivado da indústria agroalimentar produtora de sumo concentrado de maçã, conhecido por bagaço de maçã, com o objetivo de avaliar condições de extração de compostos fenólicos, o teor de compostos fenólicos totais, flavonóides e proantocianidinas e ainda a atividade antioxidante. Foram efetuadas extrações a partir do bagaço de maçã variando as condições de tempo, temperatura, razão massa:volume e solvente e os extratos obtidos avaliados quanto ao seu teor em compostos fenólicos totais pelo método FolinCiocalteu. O extrato aquoso do bagaço de maçã para uma temperatura de 100 ºC a um tempo de 2x4h e concentração de 50 mg/mL, apresentou o teor de compostos fenólicos mais elevado (9,37 mgEAG/g de bagaço de maçã, na base seca) em relação a todas as outras temperaturas, tempos de extração e solventes utilizados, como etanol (50% e 70%) e metanol. O doseamento de flavonóides totais baseou-se no método espetrofotométrico, usando o reagente cloreto de alumínio e a rutina como padrão. Os melhores resultados foram obtidos usando etanol (70%) como solvente à temperatura ambiente, cerca de 4,35 mgER/g. A amostra extraída com água apresentou valores bastante similares ao etanol, cerca de 4,27 mgER/g, usando uma temperatura de 100 ºC durante 2x4h. O conteúdo em proantocianidinas foi determinado pelo método 4-dimetilamino cinamaldeído (DMAC). O bagaço de maçã estudado demonstrou ser pobre no seu conteúdo de proantocianidinas, obtendo valores de 0,77 mgEEC/g. A atividade antioxidante do bagaço de maçã foi avaliada através de dois métodos distintos: 2,2-difenil-1-picril-hidrazilo (DPPH∙) e método do poder redutor (FRAP). O extrato aquoso obtido a 100 ºC a um tempo de 2x4h, demonstrou ser aquele com maior potencial, com uma capacidade antioxidante mais elevada que os restantes extratos, com valores de IC50 de 0,48 mg/mL e 0,65 mg/mL, para os métodos de DPPH∙ e FRAP, respetivamente.

Antioxidant Properties of Bee Products of Plant- Origin Part 2. Propolis and Pollen

Over the last years, the hive products such as propolis and pollen have been highlighted due to their potential health benefits, including antioxidant abilities that have been correlated with their content in phenolic compounds. Regardless of the several factors that may affect propolis and pollen antioxidant activity, these products have been shown to possess, either through the use of in vitro or in vivo models, important features concerning the modulation of cellular oxidative stress caused by environmental factors (e.g. UV-light), metals, pesticides and other xenobiotics. This modulatory effect focus not only on the capture of radicals that these elements might eventually generate, but also by the activation of cellular antioxidant mechanisms such as enzymatic antioxidants or by modifying gene expression patterns. Although the mechanisms behind these responses are not fully known, it has been showed that caffeic acid phenethyl ester, pinocembrin and chrisin are some of the compounds responsible for some of these responses. Taking into account the gathered results, propolis and pollen can be viewed as potential agents in the re-stabilization of cellular oxidative imbalance and in the prevention of oxidative stress related diseases.

Bivalirudin for Alternative Anticoagulation in Extracorporeal Membrane Oxygenation: A Systematic Review.

BACKGROUND Extracorporeal membrane oxygenation (ECMO) offers therapeutic options in refractory respiratory and/or cardiac failure. Systemic anticoagulation with heparin is routinely administered. However, in patients with heparin-induced thrombocytopenia or heparin resistance, the direct thrombin inhibitor bivalirudin is a valid option and has been increasingly used for ECMO anticoagulation. We aimed at evaluating its safety and its optimal dosing for ECMO. METHODS Systematic web-based literature search of PubMed and EMBASE performed via National Health Service Library Evidence and manually, updated until January 30, 2016. RESULTS The search revealed 8 publications relevant to the topic (5 case reports). In total, 58 patients (24 pediatrics) were reported (18 received heparin as control groups). Bivalirudin was used with or without loading dose, followed by infusion at different ranges (lowest 0.1-0.2 mg/kg/h without loading dose; highest 0.5 mg/kg/h after loading dose). The strategies for monitoring anticoagulation and optimal targets were dissimilar (activated partial thromboplastin time 45-60 seconds to 42-88 seconds; activated clotting time 180-200 seconds to 200-220 seconds; thromboelastography in 1 study). CONCLUSION Bivalirudin loading dose was not always used; infusion range and anticoagulation targets were different. In this systematic review, we discuss the reasons for this variability. Larger studies are needed to establish the optimal approach with the use of bivalirudin for ECMO.
