Where do food likes and dislikes come from?

2020

Where do food likes and dislikes come from ? In other words, what are the factors that could explain why someone likes or dislikes a given food ? Most of the hedonic reactions to sensory stimulations brought by foods and, as a result reactions to foods carrying these sensory properties are learned through different learning mechanisms. The efficiency of these learning mechanisms mat depend on individual characteristics, in particular on the sensitivity to different sensory properties. Not all learnings are related to experiments with the food itself; many leamings depend on interactions within the family or social environment. Finally, cognitive determinants play also a role and, in particu…

Anamorphoses du fantastique et identités des personnages dans 'Adieu' d’Honoré de Balzac

2019

Adieu, breve e drammatica novella pubblicata da Balzac nel 1830, si pone all’incrocio di generi letterari diversi (romanzo storico, récit d’aliéné ecc.) sui quali prevale una tonalità fantastica che ricorre sotto varie forme nel corso della narrazione. Questo articolo si propone di dimostrare come l’alternanza dei registri narrativi incida significativamente sullo statuto identitario dei personaggi e come per essi sia possibile trovare un’interessante chiave di lettura nelle anamorfosi del fantastico. Adieu, short and dramatic novel published by Balzac in 1830, stands at the intersection of different literary genres (historical novel, récit d’aliéné etc.) on which prevails a fantastic tonal…

Rompé tus barreras: Un análisis sobre el uso del coaching ontológico en la plataforma de entrenamiento de Nike en Buenos Aires

2020

In recent times, coaching has become relevant in heterogeneous discourses and practices in the economic, political and cultural fields of contemporary societies. Based on our ethnographic analysis of different training sessions on the Nike+ Run Club platform in Buenos Aires, in this article we study how ontological coaching operates in the field of sport and races. Then, we ask about how people who attend this platform appropriate coaching techniques to manage emotions, moods, and body effects according to the business entrepreneurship logic. Through this work, the ethnographic results are articulated with a reflection about the theory, practice, and values of the ontological coaching, wher…

Cultural industries: Product-market characteristics, management challenges and industry dynamics

2015

During the last decade, cultural industries have grown in economic importance, and research interest in them has increased. Despite prolific research, there is a lack of a comprehensive view on the subject. The purpose of the present paper is to offer a reconceptualization of cultural industries by tracing their boundaries, their features and the dynamics that follow from these features. This is achieved through a review of 314 cultural industries studies, whereby a classification system of three main and six sub-categories is constructed. On the basis of the review, a framework for future research is presented. Most importantly, future research should examine selection criteria and selecti…

Characterization of Cobalt Catalysts on Biomass-Derived Carbon Supports

2017

Cobalt catalysts are known to have a high activity and selectivity in the Fischer–Tropsch reaction converting synthesis gas to higher hydrocarbons (C5+). These catalysts have been supported by different porous materials. Porous carbon materials like activated carbon (AC) have physical and chemical surface properties that affect the preparation of supported metal catalysts and can easily be tailored. In this study, AC was produced by carbonization and steam activation of lignin, a waste fraction from the Kraft pulping process. A series of Co/AC-catalysts was produced and characterized by several techniques. According to the results, tailored properties (high surface area, mesoporosity) were …

Correlations of blood selenium with hematological parameters in West German adults.

1988

The serum selenium and the whole blood selenium of 72 healthy persons (47 women, 25 men) was determined. There exist sex specific differences of the whole blood selenium between men (98 +/- 19 micrograms Se/L) and women (89 +/- 17 micrograms Se/L). The serum selenium did not show sex specific differences, but sex specific differences are found if the total amount of extracellular selenium is calculated by correction of the serum selenium with the hematocrit. Women have more extra-cellular selenium/L whole blood (40 +/- 8 micrograms Se) than men (36 +/- 7 micrograms Se). Men have more intraerythrocyte selenium (cellular selenium = 67 +/- 14 micrograms Se) in one L whole blood than women (52 …

Characterization of high-temperature performance of cesium vapor cells with anti-relaxation coating

2017

© 2017 Author(s). Vapor cells with antirelaxation coating are widely used in modern atomic physics experiments due to the coating's ability to maintain the atoms' spin polarization during wall collisions. We characterize the performance of vapor cells with different coating materials by measuring longitudinal spin relaxation and vapor density at temperatures up to 95 °C. We infer that the spin-projection-noise-limited sensitivity for atomic magnetometers with such cells improves with temperature, which demonstrates the potential of antirelaxation coated cells in applications of future high-sensitivity magnetometers.

Formation and characterization of oxidic and metallic Fe/Ni multilayers prepared from Langmuir-Blodgett films

1994

Oxidic and metallic iron, nickel, and mixed iron/nickel mono- and multilayers were prepared by some treatments of iron- and nickel-containing Langmuir-Blodgett films. The layers were characterized by several surface-sensitive methods. Interactions between the iron and the nickel could be observed. The results are different to those obtained from disordered bulk alloys and from simple diffusion calculations.

Prediction of properties of chiral compounds by molecular topology

1998

Abstract A common assumption in chemistry is that chiral behavior is associated with 3-D geometry. However, chiral information is related to symmetry, which allows the topological handling of chiral atoms by weighted graphs and the calculation of new descriptors that give a weight to the corresponding entry in the main diagonal of the topological matrix. In this study, it is demonstrated that, operating in this way, chiral topological indices are obtained that can differentiate the pharmacological activity between pairs of enantiomers. The 50% inhibitory concentration (IC50) values of the D2 dopamine receptor and the σ receptor for a group of 3-hydroxy phenyl piperidines are specifically pr…
