    Supplementation of omega-3 fatty acids is considered a valuable strategy to supply the low intake of these fatty acids. Thus, the safety of the supplements is an important milestone. Because of that, we analyzed 20 unflavored supplements sold in the French market for fatty acid and triglyceride composition, for EPA and DHA, and for tocol content, as well as for oxidative status. This study found that only 2.5% of the supplements did not meet their label claims for omega-3 content. TAG analysis showed high variability among the triglyceride distribution, and the same trend was also noticed for the tocol content; in fact, a high variability of the distribution of the six tocols (four tocopherols and two tocotrienols) was found among the samples. Of the tested products, all of them complied with peroxide value, p-anisidine value, and Totox values established by the Global Organization for EPA and DHA Omega-3s (GOED) and were not oxidized.Spanish Ministry of Science, Education and Universities/Spanish State Research Agency PCI2018-093178European Commissio

    History of Construction Cultures Volume 2

    Volume 2 of History of Construction Cultures contains papers presented at the 7ICCH – Seventh International Congress on Construction History, held at the Lisbon School of Architecture, Portugal, from 12 to 16 July, 2021. The conference has been organized by the Lisbon School of Architecture (FAUL), NOVA School of Social Sciences and Humanities, the Portuguese Society for Construction History Studies and the University of the Azores. The contributions cover the wide interdisciplinary spectrum of Construction History and consist on the most recent advances in theory and practical case studies analysis, following themes such as: - epistemological issues; - building actors; - building materials; - building machines, tools and equipment; - construction processes; - building services and techniques ; -structural theory and analysis ; - political, social and economic aspects; - knowledge transfer and cultural translation of construction cultures. Furthermore, papers presented at thematic sessions aim at covering important problematics, historical periods and different regions of the globe, opening new directions for Construction History research. We are what we build and how we build; thus, the study of Construction History is now more than ever at the centre of current debates as to the shape of a sustainable future for humankind. Therefore, History of Construction Cultures is a critical and indispensable work to expand our understanding of the ways in which everyday building activities have been perceived and experienced in different cultures, from ancient times to our century and all over the world

    Scrap your boilerplate with object algebras

    International audienceTraversing complex Abstract Syntax Trees (ASTs) typically requires large amounts of tedious boilerplate code. For many operations most of the code simply walks the structure, and only a small portion of the code implements the functional- ity that motivated the traversal in the first place. This paper presents a type-safe Java framework called Shy that removes much of this boilerplate code. In Shy Object Algebras are used to describe complex and extensible AST structures. Using Java annotations Shy generates generic boilerplate code for various types of traversals. For a concrete traversal, users of Shy can then inherit from the generated code and over- ride only the interesting cases. Consequently, the amount of code that users need to write is significantly smaller. Moreover, traversals using the Shy framework are also much more structure shy, becoming more adaptive to future changes or extensions to the AST structure. To prove the effectiveness of the approach, we applied Shy in the implementation of a domain-specific questionnaire language. Our results show that for a large number of traversals there was a significant reduction in the amount of user-defined code

    The Silences of Dispossession. The Dynamics of Agrarian Change and the Politics of Indigenous People in Chaco, Argentina

    Get PDF
    Recent studies of ‘accumulation by dispossession’ have highlighted the link between agrarian changes and the expansion of social capitalist relationships that has occurred in the neoliberal era. However, the high degree of abstraction of these studies and the lack of analysis of the role of the actors involved in these processes, especially the subaltern groups, presents challenges for the analysis of empirical processes (Hart, 2002; 2004; Hall, 2013). To overcome these limitations this work proposes to analyze processes of agrarian change through an approach centred on the ‘local rationalities’ of the actors involved (Nilsen and Cox, 2013). From that perspective this thesis argues that the positions of the actors in ‘processes of accumulation by dispossession’ can be explained by examining their memories of past experiences, the actual forms of power and dispossession and the position of subalternity of each group in a determined time and place (Li, 2000; Hodgson, 2011). The focus on local rationalities is applied here to analyze the different perceptions and positions of two indigenous communities in the province of Chaco, Argentina with regard to the expansion of the agribusiness model since the 1990s. This work thus seeks to illuminate the multiple dynamics that exist between subaltern and dominant groups in the different contexts of dispossession. Through analyzing these processes by considering the complex network of power relationships that have been produced, which generate acts of resistance but also complicity, this approach aims to make a contribution that will help to revitalize political readings of new rural dynamics linked to capitalist development

    Gears4Net - Ein Programmiermodell fĂŒr asynchrone Kommunikation in P2P-Systemen

    Get PDF
    Die vorliegende Arbeit betrachtet die Herausforderungen bei der Entwicklung massiv paralleler, verteilter Systeme. Am Beispiel des ortsbezogenen Peer-to-Peer-Systems Symstry werden geeignete Modelle zur KomplexitĂ€tsreduktion des Softwareentwicklungsprozesses abgeleitet sowie Verfahren zur Simulation derartiger Systeme etabliert. Die Arbeit ist in drei Themenschwerpunkte gegliedert. Der erste Schwerpunkt betrachtet die aktuell bestehenden Softwareentwicklungsmethoden im Hinblick auf den zunehmenden Parallelisierungsgrad und die daraus entstehenden Implikationen auf den Softwareentwicklungsprozess. Abgeschlossen wird dieses Kapitel mit dem Entwurf und der Implementierung des Programmiermodells Gears4Net. Dieses erlaubt die Betrachtung von ParallelitĂ€t als Designkriterium und forciert sowohl die synchronisationsfreie Anwendungsimplementierung als auch die Zustandsmaschinen-Ă€hnliche Quellcodestrukturierung. Im Fokus des zweiten Schwerpunktes steht die Konzeption und Implementierung des Peer-to-Peer-Systems Symstry. Symstry, das auf Basis des Gears4Net-Modells entwickelt und simuliert wurde, verfolgt den Ansatz symbolischer Adressierung zur Spezifikation von EndgerĂ€ten, Orten und Regionen. Der besondere Schwerpunkt dieses Themenkomplexes liegt bei der Konzeption effizienter Routing- beziehungsweise Geo-Cast- oder Range-Query-Verfahren. Abgeschlossen wird die Arbeit mit dem dritten Schwerpunkt, der Simulationsumgebung Inspector. Diese ermöglicht die komponentenweise Simulation beziehungsweise Emulation der auf Basis des Gears4Net-Modells entwickelten Softwarekomponenten und bildet die Grundlage fĂŒr die Evaluation des Peer-to-Peer-Systems Symstry
