[pt] Esta tese parte de uma provocação enunciada pela personagem Alcibíades em seu discurso no diálogo Banquete de Platão: Nenhum de vocês o conhece bem. Esta frase versa a respeito da ininteligibilidade e consequente incomparabilidade de Sócrates, identificada pelo simposiasta como atopía, um não-lugar. Partindo, então, deste termo, buscamos aqui analisar as pistas que a personagem que discursa sobre o filósofo apresenta acerca dele, correlacionandoas a outras que ocorrem na obra platônica em geral e que consolidam a atopia de Sócrates. Assim, desenvolvemos uma análise de Sócrates enquanto um ser atópico tanto em sua fisionomia, como em seu comportamento e palavras, sendo estas três áreas da vida do filósofo o que chamamos nesta tese de eixos, bases metodológicas segundo as quais desenvolveremos a análise da sua atopia. Como fio condutor principal de todos estes eixos, teremos a presença central das figuras divinas de Eros e Dioniso, ambas apresentadas no Banquete como sendo os principais referenciais a partir dos quais Sócrates viverá a sua atopia. No campo de Eros, analisaremos o fundamento da narrativa de Diotima acerca deste deus, com seu caráter intermediário e daimônico, que será associado a Sócrates de forma evidente na fala da sacerdotisa de Mantineia. Já quanto ao aspecto dionisíaco, ele surgirá permeando todo o diálogo, mas será encontrado, em especial, na figura dos sátiros e silenos, seres mitológicos do círculo dionisíaco que serão associados a Sócrates por Alcibíades. Postulamos, assim, como tese central deste trabalho, que Sócrates é atópos porque a sua filosofia será um exercício integrado de seu corpo, de seus atos e de suas palavras, como partes de seu ser erótico e dionisíaco. / [en] This thesis is part of a provocation enunciated by the character Alcibiades in his speech in Plato s Symposium dialogue: None of you know him well. This phrase concerns the unintelligibility and consequent incomparability of Socrates, identified by the symposiasta as atopy, a non-place. Beginning from this term, we reach to analyze the clues that the character speeches about the philosopher presents about him, correlating them to others, that occurs in the Platonic piece in general and that consolidates the atopy of Socrates. Thus, we developed an analysis of Socrates as an atopic being both in his physiognomy as in his behavior and words, these three areas of the philosopher s life being what we call this thesis of axes, methodological bases according to which we ll develop the analysis of his atopy. As the main thread of all these axes, we will have the central presence of the divine figures of Eros and Dionysus, both presented at the Symposium as the main references from which Socrates will live his atopy. In Eros field, we will analyze the foundation of Diotima s narrative about this god, with his intermediate and daimonic character, which will be associated with Socrates in an evident way in the speech of the priestess of Mantineia. In the matter of the Dionysian aspect, it will appear permeating the whole dialogue, but will be found, in particular, in the figure of the satyrs and silenos, mythological beings of the Dionysian circle that will be associated with Socrates by Alcibiades. We postulate, therefore, as the central thesis of this work, that Socrates is atomic because his philosophy will be an integrated exercise of his body, his acts and his words, as parts of his erotic and Dionysian being.

This thesis explores ancient ideas regarding the constructive properties of intoxicating drinks, as presented in Greco-Roman sources from the first to third centuries AD. In doing so, it responds to Mary Douglas' Constructive Drinking (1987), which emphasised that, contrary to anthropological findings, many societies' authorities tend to focus upon, and overemphasise, the destructive aspects of alcohol consumption. This pattern is particularly prevalent in modern Western scholarship. The same trend can be detected within both Greco-Roman society and classical scholarship. Although many Greeks and Romans undoubtedly consumed quantities of wine, on a regular basis, in a manner which was widely considered 'moderate', the literary evidence from this period tends to focus most heavily upon excessive and/or destructive drinking. Similarly, much of the modern scholarship which addresses drinking in the Roman Empire focuses upon drunkenness and the destructive aspects of drinking. Yet it is clear that Greco-Roman society considered wine consumption to be significantly beneficial, in a wide variety of ways, provided that moderation was employed. The destructive consequences of drinking were almost exclusively associated with excessive and inappropriate consumption. In reaction to this bias in the sources and scholarship, this thesis undertakes a re-reading of the ancient evidence through the 'Constructive Drinking' lens. It identifies and explores the ways in which the Greeks and Romans of this period considered drinking to be important, useful, or otherwise 'constructive' to the individual and society. Where possible, this thesis attempts to identify how important and widespread such beliefs were. This thesis has two main areas of focus. First, the ways in which intoxicating drink was considered to be constructive for an individual's health and wellbeing. Second, the ways in which intoxicating drink was considered to be of social benefit to both individuals and groups. This thesis accordingly provides a fresh perspective on drinking in antiquity, and illustrates the methodological significance of the Constructive Drinking lens for future research.

Le présent mémoire se penche sur la dramaturgie que mettent en scène le Banquet et le Phédon de Platon. Dans le cas du premier dialogue, une étude de l'épilogue et du discours d'Alcibiade, assortie de parallèles ponctuels dans la République et la Lettre VII, permet de déceler un exemple de la rétention d'information platonicienne, telle que comprise sous l'égide des écoles platoniciennes de Tübingen et de Milan, de même qu'une attestation de l'existence de doctrines non-écrites qualitativement supérieures à celles que renferment les dialogues. L'épilogue du Banquet fait ensuite, à la lumière des conclusions susmentionnées, l'objet d'une interprétation qui distingue trois niveaux de lecture des dialogues platoniciens : l'extériorité, l'intériorité et l'oralité philosophique, symbolisées respectivement par le poète comique Aristophane, le poète tragique Agathon et le poète philosophique Socrate. Il va de soi que ce dernier renvoie sémantiquement au philosophe par excellence, titre que Platon endosse volontiers. L'essai exégétique touchant le Phédon se concentre pour sa part sur la dernière volonté de Socrate. Celle-ci survient au dénouement de la partie la plus « dramaturgique » du dialogue, c'est-à-dire après les discours proprement philosophiques sur l'immortalité de l'âme. En ciblant ces moments, de même que l'introduction, nous distinguons l'adjonction des tons tragique et comique, illustrant par là un procédé inhabituel dont le but, ultimement, est de soustraire le dialogue au registre tragique afin d'éviter la propagation d'émotions contraires à la philosophie. En exploitant l'oxymore comique-tragique sur un plan mimétique, nous montrerons que la dernière volonté de Socrate véhicule un dessein parénétique. / The present work has as its main focus Plato's dramaturgy in the Symposium and the Phaedo. The former studies both Alcibiades' speech and the epilogue whilst paralleling some of their elements with relevant passages from the Republic and the Seventh Letter. In doing so, it reveals an instance of Socratic withholding of information - as understood by the platonic school of Tübingen and Milan - and sheds light upon the existence of a set of unwritten doctrines philosophically higher than the ones contained in the dialogues. On the basis of these conclusions, I come to discern a hermeneutics in the epilogue according to which there are three hierarchical levels of comprehension to Plato's dialogues: exteriority, interiority of and oral philosophy - said three levels being symbolised by the comic poet Aristophanes, the tragic poet Agathon and the philosopher Socrates. The exegetic essay on the Phaedo revolves around Socrates' last will, which comes at the end of a ''dramatic'' sequence exceeding the bounds of the discursive philosophy that seeks to prove the immortality of the soul during the major part of the dialogue. By aiming at this sequence as well as at the introduction, one comes to see that comedy carries the mandate of counterbalancing tragedy in order to overcome the philosophically reprehensible emotions it fosters. Whilst contrasting tragedy and comedy, Socrates' last words fulfill, on a mimetic level, a paraenetic design, insofar as they invite the Athenian reader, indeed every reader, to philosophically overcome common places in regards to death.

Many scholars who study Plato and Shakespeare together focus only on erotic love between lovers or nonsexual love between others. A closer study of A Midsummer Night’s Dream shows that Shakespeare uses Plato’s concepts of the soul in addition to the Forms, the guide, as well as staging the varieties of love that can exist between two individuals and the dangers of loving the physical more than the mind. Shakespeare takes these ideas embedded in Symposium and Phaedrus and not only crafts his play accordingly, but also creates his own versions through his unique interpretations. These alterations appear reflected in the play’s sequence of events, the characters’ actions, and the merging of the faerie and human realms. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Verpackungen sind aus unserem täglichen Leben nicht mehr wegzudenken. Sie tragen durch ihre Schutzfunktion zum Erhalt der Produktqualität bei, ermöglichen eine effektive Logistik und minimieren die Kosten in der Lieferkette. Der aktuell am weitesten verbreitete Kunststoff aus nachwachsenden Rohstoffen (Biokunststoff) ist Polymilchsäure (PLA, englisch polylactic acid).

Der Beitrag berichtet, wie im Rahmen eines Forschungsvorhabens, welches durch das BMWi über einen Zeitraum von zwei Jahren gefördert wurde, ist untersucht worden, inwieweit der nachwachsende Rohstoff Miscanthus zur Herstellung von Verpackungen genutzt werden kann. Hierbei wurden zwei Verfahren, das Fasergussverfahren und das additive Fertigungsverfahren 3D-Printing, betrachtet. Beteiligt waren drei KMU und zwei gemeinnützige Forschungseinrichtungen.

Die Anwender von Reinigungstechnik stehen vor ständig neuen und wachsenden Herausforderungen. Steigende Qualitätsansprüche und zunehmender Kostendruck verlangen ein sicheres Beherrschen der Reinigungsprozesse und deren Steuerung für stabile Sauberkeit. Der folgende Tagungsbeitrag beschäftigt sich mit diesem Thema.

Meine Präsentation beschreibt die „Einsparpotentiale bei der CIP-Reinigung von Produktionsanlagen durch konsequentes Hygienic Design“ und basiert auf der Diplomarbeit von Andreas Dorner, Technische Universität München. Es ist eine Analyse des möglichen Einsparpotentials für die Lebensmittelindustrie bei Verwendung von neuesten, hygienegerecht konstruierten Anlagenbauteilen gegenüber herkömmlichen, industriell verwendeten Bauteilen mit Hygienerisiken . Durch vergleichende Reinigungsversuche werden Ventile und Einbaugehäuse von Sensoren miteinander verglichen, um so dem Nahrungsmittelproduzenten eine Hilfestellung bei der Auswahl dieser Bauteile bei einer Neuanschaffung bzw. beim Austausch von Anlagenkomponenten hinsichtlich der Reinigbarkeit geben zu können. Bei den Untersuchungen wurden die Reinigungs- und Verschmutzungsparameter für die zu vergleichenden Bauteile konstant gehalten, um nur den Einfluss der Konstruktion auf die Reinigung zu ermitteln. Um deine gesundheitliche Bedrohung von Lebensmittel-Konsumenten zu reduzieren, bzw. so gering wie möglich zu halten ist eine gründliche Reinigung von Produktionsanlagen wichtig. Das lässt sich jedoch nur mit hygiene gerechten, totraum-freien Bauteilen erreichen, die nach der CIP-Reinigung keim arm sind. Korrektes hygienisches Design verbessert die Reinigung und Sterilisation durch verbessertem Massen- und Wärmeübergang des CIP-Reinigungsmittels. Mangelhafte Reinigung sind heute Auslöser von bis zu 20% der GMP-Beanstandungen Reinigungsschritte sind essentiell für die Lebensmittelsicherheit und können bis zu 70% des gesamten Wasserverbrauchs und der Abwassermenge eines Werkes ausmachen. Reinigung ist nicht nur aus Sicherheitsgründen ein zu beachtender Prozess, sondern birgt auch ein großes finanzielles Einsparpotential, nicht nur hinsichtlich der Wasserkosten. In der Lebensmittelindustrie werden zum Teil immer noch sinnvolle Investitionen in Hygienic Design konforme Anlagenbauteile gescheut, da sie aufgrund hoher Anschaffungskosten vermeintlich teurer erscheinen. Dabei werden jedoch die gesamten Lebenszykluskosten (Life Cycle Costs) oftmals außer Acht gelassen.

Abstract des Vortrages: The reliability-limiting effects in 3D IC structures using TSVs including mechanical stress distributions and the resulting effects on material integrity (e.g. failure modes like interface delamination, cohesive cracking, metallurgical degradation at joints, and chip-package interaction) and finally on device performance degradation are challenges in advanced 3D integration technologies and product development. Managing internal mechanical stress is a key task to ensure high reliability of products manufactured in advanced CMOS technology nodes, and it is a highly ranked concern for 3D TSV technologies. It requires the determination of materials properties, including Young’s modulus, Poisson ratio and coefficient of thermal expansion (CTE), for each material used. For polycrystalline materials, their microstructure has to be considered. In this talk, one reliability-limiting effect, interface delamination and so-called “pop-up” of copper TSV structures will be addressed. Shear stress along the Cu/Si interface and adhesion of the interfaces in a complex stack (Si/liner/barrier/seed/Cu) are parameters that have to be considered. Metal barrier and seed films and the respective surfaces will be discussed in the context of interface strength. Nano X-ray tomography is currently the only analytical technique to study the so-called “pop-up” effect quantitatively, without modifying the region of interest.
