Acute cardiovascular dysfunction occurs perioperatively in more than 20% of cardiosurgical patients, yet current acute heart failure (HF) classification is not applicable to this period. Indicators of major perioperative risk include unstable coronary syndromes, decompensated HF, significant arrhythmias and valvular disease. Clinical risk factors include history of heart disease, compensated HF, cerebrovascular disease, presence of diabetes mellitus, renal insufficiency and high-risk surgery. EuroSCORE reliably predicts perioperative cardiovascular alteration in patients aged less than 80 years. Preoperative B-type natriuretic peptide level is an additional risk stratification factor. Aggressively preserving heart function during cardiosurgery is a major goal. Volatile anaesthetics and levosimendan seem to be promising cardioprotective agents, but large trials are still needed to assess the best cardioprotective agent(s) and optimal protocol(s). The aim of monitoring is early detection and assessment of mechanisms of perioperative cardiovascular dysfunction. Ideally, volume status should be assessed by 'dynamic' measurement of haemodynamic parameters. Assess heart function first by echocardiography, then using a pulmonary artery catheter (especially in right heart dysfunction). If volaemia and heart function are in the normal range, cardiovascular dysfunction is very likely related to vascular dysfunction. In treating myocardial dysfunction, consider the following options, either alone or in combination: low-to-moderate doses of dobutamine and epinephrine, milrinone or levosimendan. In vasoplegia-induced hypotension, use norepinephrine to maintain adequate perfusion pressure. Exclude hypovolaemia in patients under vasopressors, through repeated volume assessments. Optimal perioperative use of inotropes/vasopressors in cardiosurgery remains controversial, and further large multinational studies are needed. Cardiosurgical perioperative classification of cardiac impairment should be based on time of occurrence (precardiotomy, failure to wean, postcardiotomy) and haemodynamic severity of the patient's condition (crash and burn, deteriorating fast, stable but inotrope dependent). In heart dysfunction with suspected coronary hypoperfusion, an intra-aortic balloon pump is highly recommended. A ventricular assist device should be considered before end organ dysfunction becomes evident. Extra-corporeal membrane oxygenation is an elegant solution as a bridge to recovery and/or decision making. This paper offers practical recommendations for management of perioperative HF in cardiosurgery based on European experts' opinion. It also emphasizes the need for large surveys and studies to assess the optimal way to manage perioperative HF in cardiac surgery.

Die Dissertation bietet eine neue Sichtweise auf die Autorin Annemarie Schwarzenbach, die in den 1930er Jahren im Feuilleton der renommiertesten Schweizer Zeitungen - wie der NZZ, der Weltwoche oder auf den besten Doppelseiten der illustrierten Zeitschriften - überaus präsent war. Im Zentrum der Analyse steht das journalistische Werk Schwarzenbachs mit ca. 300 Reportagen und Feuilletons, die im Zeitraum von 1930-1942 erschienen sind. Die Studie erlaubt einen Einblick in wenig erforschtes und zum Teil unveröffentlichtes Material, das in den für Schwarzenbach relevanten Nachlässen und Zeitungsarchiven in großen Schweizer Bibliotheken ausgewertet wurde. Zu den konsultierten Institutionen gehören die Schweizerische Nationalbibliothek (NB) in Bern, das Schweizerische Literaturarchiv (SLA), das Robert Walser-Zentrum in Bern, die Zentralbibliothek Zürich (ZBZ) und die Universitätsbibliothek Basel (UB Basel). Zu den ausgewerteten Beständen zählen die Zürcher Illustrierte, Sie und Er, Annabelle, die Basler National-Zeitung, Die Tat, Luzerner Tagblatt, Thurgauer Zeitung, Die Weltwoche und ABC. Erst die Arbeit an den Originalartikeln in den Zeitungen ermöglicht präzise Aussagen zum Aufbau und Stil der Texte; das impliziert die Untersuchung der einzelnen Textstufen - vom Typoskript bis zum gedruckten Artikel. Das publizistische Profil der Zeitungen wurde analysiert und in Beziehung zu den jeweiligen Beiträgen Schwarzenbachs gesetzt. Die Arbeit ist als Text- Kontext-Studie angelegt. Das Projekt veranschaulicht die Entwicklung einer Schriftstellerin, die in ihren literarischen Anfangen eher einem poetologischen Prinzip folgt, das sich klassische Modelle der dichterischen , Inspiration' zum Vorbild nimmt und sich an zeitgenössischen Dichtern wie Rilke und George orientiert. Über das Medium der Zeitung findet die Autorin zu einem neuen Stil: Im Spannungsfeld von subjektiv-lyrischem Anspruch und der Orientierung am Sachlichkeitswert und Authentizitätspostulat entstehen Schwarzenbachs journalistische Arbeiten. In dieser Hinsicht ist die Autorin keine literarische Außenseiterin, trotz ihrer außergewöhnlichen Biografie und Lebenssituation. Sie teilt in ihrer Hinwendung zum feuilletonistischen und journalistischen Schreiben die literarischen Existenzbedingungen einer ganzen Generation von Grenzgängern zwischen Literatur und Journalismus, von Musil, Roth bis zu Kerr, Kisch, Toller und Benjamin. Annemarie Schwarzenbach akzentuiert aber dabei die Reportage als Medium der Fremderfahrung und fuhrt sie gleichzeitig an ihren historischen Ursprung im Reisebericht zurück.

A ampliação da oferta de tangerinas tanto no mercado interno como no externo é limitada pela grande quantidade de sementes nos frutos das principais cultivares, danos na casca resultante de doenças e pela pequena produção nas épocas mais quentes do ano. O presente trabalho teve como objetivo caracterizar a qualidade dos frutos e a época de maturação de 46 tangerinas e híbridos em condições de campo na Estação Experimental de Citricultura de Bebedouro (EECB), Bebedouro-SP. As variedades de tangerinas e híbridos (tangores e tangelos) foram introduzidas de bancos de germoplasma da Itália, Portugal, Espanha e França, e a pesquisa desenvolveu-se durante os anos agrícolas de 2001/2002 e 2002/2003. Foram avaliadas características externas de qualidade, como altura e diâmetro dos frutos, massa dos frutos, facilidade em descascar com a mão e características internas como: número de sementes, teor de sólidos solúveis totais, acidez total titulável, rendimento em suco, "ratio" e rendimento em polpa. Duas cultivares apresentaram frutos de boa qualidade e época de maturação precoce, podendo ser disponibilizadas no mercado, num período de escassez deste tipo de citros, e serem alternativas à tangerina-'Cravo'. Quatro cultivares que apresentaram boa qualidade e maturação mediana poderão ser alternativas à 'Poncã'.

In looking at the Europeanization of the German Bundestag, the paper brings together two different debates: the well-established debate on the democratic legitimacy of the European Union sees national Parliaments as guarantor of one branch of a "dual" legitimacy. The more recent debate on "Europeanization" addresses the impacts that European integration has had on its Member States. Analyzing the Europeanization of the German Bundestag, the paper identifies and analyzes three dimensions: legislative Europeanization – the extent to which legislative decision making by the German Bundestag has been influenced by European stipulations over the last twenty years; institutional Europeanization – how the Bundestag as an institution reacted to this loss of function by establishing institutional and procedural provisions for influencing the government's Euro-politics; and strategic Europeanization – the ways in which individual MPs started more recently to develop euro-political strategies that go beyond controlling the national government. The paper shows that the Bundestag only hesitantly reacted to the increasing loss of functions through legislative Europeanization by establishing effective institutional and procedural provisions for controlling the government's Euro-political activities. What is more, the establishment of institutions does not guarantee their effective use. All in all, Euro- politics continues to remain the activity of few MPs. These few, however, have more recently started to europeanize their strategies. The empirical findings support the claim that the traditional concept of chains of legitimacy is inadequate, both in conceptual and in empirical terms. With regard to the democ- ratic legitimacy of EU governance, this indicates that, apart from major reform projects, especially with regard to everyday legislation, not too great a burden should be placed on national Parliaments.

Since the study of Large Dam Reservoirs is of worldwide interest, in this PhD project we investigated the Ridracoli reservoir, one of the main water supply in Emilia-Romagna (north-eastern Italy). This work aims to characterize waters and sediments to better understand their composition, interactions and any process that occurs, for a better geochemical and environmental knowledge of the area. Physical and chemical analyses on the water column have shown an alternation of stratification and mixing of water in the reservoir’s water body due to seasonal variations in temperature and density. In particular, it was observed the establishment, in late summer, of anoxic conditions at the bottom, which in turn affects the concentration and mobility of some elements of concern (e.g. Fe and Mn) for the water quality. Sediments within the reservoir and from surrounding areas were analysed for organic matter, total inorganic composition and grain size, assessing the inter-element relationship, grain size, geological background and damming influences on their chemistry, through descriptive statistics, Principal Component Analysis and Cluster Analysis. The reservoir’s area was also investigated by pseudo total composition (Aqua Regia digestion), degree of elements extractability, and enrichment factors, then analysed and compared to limits by law and literature. Sediment cores, interstitial waters, and benthic chamber data from the bottom were of great interest due to organic matter degradation, early diagenesis, mineral formation at water-sediment interface and observed flows. Finally, leaching test and extraction procedures, of environmental interest, showed peculiar partitioning, both regarding spatial and in-depth distribution, and the absence of pollution. Collectively, our results are useful for the comprehension of processes that occur in water and sediments of Ridracoli reservoir, providing important knowledges on the site that could be relevant for the management of the resource and the planning of future interventions.
