Study of relationships between the structure of aroma compounds and their retention-release between vapour phase and dairy gels

2010

An integrated approach physicochemistry and structures activity relationships has been carried out to study the aroma compounds retention-release phenomenon in a fat free dairy gel added with pectin. This study aimed to identify the molecular properties that govern this phenomenon assuming that modifying the structure leads automatically to a change in the retention-release of aroma compounds. For this purpose, we have determined the partition coefficients of 28 aroma compounds in water, in pectin gels and in dairy gels supplemented or not supplemented with pectin, at equilibrium conditions using the PRV method (Phase Ratio Variation). Then, we have performed a structure-retention relations…

Current debates on online privacy are rooted in liberal theory. Accordingly, privacy is often regarded as a form of freedom from social, economic, and institutional influences. Such a negative perspective on privacy, however, focuses too much on how individuals can be protected or can protect themselves, instead of challenging the necessity of protection itself. In this article, I argue that increasing online privacy literacy not only empowers individuals to achieve (a necessarily limited) form of negative privacy, but has the potential to facilitate a privacy deliberation process in which individuals become agents of social change that could lead to conditions of positive privacy and infor…

Messung der gesamtaktivität von glutamat-oxalacetat-transaminase in leberhomogenaten

1971

Abstract A method is described, suitable for routine measurements of the total glutamicoxaloacetic transaminase activity in a large number of liver samples by treatment of homogenates with the detergent Triton X-100. Comparison with other methods and with results of other investigators shows that this method is superior. Neither sonic treatment nor freezing and thawing leads to a complete liberation of the mitochondrial transaminase activity. A number of other enzyme activities can be assayed in Triton-treated homogenates, such as glutamic-pyruvic transaminase, glutamate dehydrogenase, NADP-isocitric dehydrogenase, lactate dehydrogenase, and malate dehy drogenase, β-Hydroxybutyrate dehydrog…

Characterization of the Proteinases Present in Germinating Seeds of Scots Pine, Pinus sylvestris

1978

Methods were developed to determine proteinase activity in germinating seeds of Scots pine. The assays were based on the liberation of TCA-soluble peptides from haemoglobin at pH 3.7 and from casein at pH 5.4 and pH 7.0; the reaction products were determined by the Lowry method. — Endosperms separated from seeds at the time of rapid storage protein mobilization (seedling length between 20 and 50 mm) showed high proteinase activities in all three assays. Experiments with different inhibitors suggested that at least four enzymes were involved. One of the enzymes resembled mammalian and microbial pepsin-like acid proteinases: the pH optimum was 3.7 and the enzyme was inhibited by pepstatin.—Th…

Does Public Deliberation really Need Normative Constraints? Recovering the Aristotelian Rhetorical Theory

2016

There was recently an attempt to correlate some sectors of the studies on argumentation and the theory of democracy. The relationship between these two areas concerns the fact that in both cases there is a significant interest in normative models of good argumentation. In these models there is no place for rhetoric. Our work has a twofold aim: (1) to show that, starting from the Aristotelian rhetoric, it is possible to develop a more suitable model of argumentation in the public sphere and (2) to doubt the very need to identify normative constraints for this type of argument.

Return to politics Uncertainty, debate and political action in the theory of democracy Benjamin R. Barber

2014

La teoría de Benjamin Barber ha renovado por varias razones su actualidad al cumplirse 30 años de la edición de Strong Democracy. Me interesa desarrollar en este artículo la relación que Barber establece entre la necesidad de la acción política, la incertidumbre epistemológica del ámbito político y la deliberación. Reconocer esta relación puede ayudarnos a explicar la inevitabilidad de la política y, por tanto, retornar a ella. No cabe duda de que en nuestros tiempos globalizados es fácil reconocer la necesidad de la acción y la incertidumbre, por lo que la teoría de Barber puede indicarnos cómo sobrellevarlas. Si la propuesta de Barber fue en su momento una inspiración para nuestras preten…

Arguments and counter-arguments in the debate to decriminalize some forms of incestuous relations in Poland

2018

This study explores argumentation and counter-argumentation patterns emerging from a corpus of readers’ comments found below-the-line of over twenty-five online articles on the subject of incest, the current legal sanctions against it and the possibility to decriminalize consensual incestuous relations between adults in Poland. The comments have been coded line-byline for the types of positioning and argument premises using Atlas.ti software. Using the framework for argument analysis according to underlying premises, the comments were analyzed with respect to stance taken, practical reasoning conducted, and salient rhetorical strategies applied. They are subsequently correlated with the dis…

A comparison between three ideal types of parliamentary politics : representation, legislation and deliberation

2018

Representative, legislative and deliberative assemblies are commonly called parliaments. The three types of assemblies share many procedures and practices, and the Inter-Parliamentary Union includes all three types among its members. Nonetheless, as ideal types in the Weberian sense, the three kinds of political assemblies do differ in their modes of acting and thinking politically. This article is a thought experiment to sketch the three ideal types by working out a number of key aspects of their distinctive political features. The political action that characterizes representative assemblies is pre-parliamentary elections, legislative assemblies are judged by their post-parliamentary resu…

Ciudadanía democrática: ética, política y religión. XIX Conferencias Aranguren

2011

This article is comprised of two parts, bound together by the concept of <i>democratic citizenship</i>. The first part attempts to design the lines of <i>deliberative democracy</i> as the most appropriate model to embody the actual substance of democracy. That is why it presents the sense of deliberative democracy, its traits, its advantages compared with other models, the conditions for its start-up, its limits and the specific type of deliberative democracy that would be more adequate, and which receives the name of «communicative democracy»; all of this by way of dialogues with its main representatives. The second part addresses the specific questions of the <i…
