Determination of the complexing capacity of synthetic and real wine for Zn using Absence of Gradients and Nerstian Equilibrium Stripping technique

The complexing capacity of synthetic (0.011 M tartrate in 13.5% ethanol) and real wine (Raimat Abadia) in titrations with added total Zn concentrations up to 0.03 M has been determined following the free Zn concentrations with AGNES (absence of gradients and Nernstian equilibrium stripping) technique. A correction to find the preconcentration factor or gain (Y1) really applied at each one of the ionic strengths reached due to Zn additions along the titration has been applied. The standard implementation of AGNES to real wine led to the observation of two anomalous behaviors: (a) an increasingly negative current in the deposition stage (labeled as “HER” effect) and (b) a minimum in the currents of the stripping stage plot (labeled as the “dip” effect). A practical strategy to apply AGNES avoiding the dip effect has been developed to quantify properly free Zn concentrations. The van den Berg–Ružic–Lee linearization method (assuming the existence of just 1:1 complexes) has been adapted to consider the dilution effect and the ionic strength changes. Aggregated stability constants and total ligand concentrations have been calculated from synthetic and wine titration data. The found complexing capacity in the studied wine (cT,L = 0.0179 ± 0.0007 M) indicates the contribution of ligands other than tartrate (which is confirmed to be the main one).

Beaming into the rat world: enabling real-time intereaction between rat and human each at their own scale

Immersive virtual reality (IVR) typically generates the illusion in participants that they are in the displayed virtual scene where they can experience and interact in events as if they were really happening. Teleoperator (TO) systems place people at a remote physical destination embodied as a robotic device, and where typically participants have the sensation of being at the destination, with the ability to interact with entities there. In this paper, we show how to combine IVR and TO to allow a new class of application. The participant in the IVR is represented in the destination by a physical robot (TO) and simultaneously the remote place and entities within it are represented to the participant in the IVR. Hence, the IVR participant has a normal virtual reality experience, but where his or her actions and behaviour control the remote robot and can therefore have physical consequences. Here, we show how such a system can be deployed to allow a human and a rat to operate together, but the human interacting with the rat on a human scale, and the rat interacting with the human on the rat scale. The human is represented in a rat arena by a small robot that is slaved to the human"s movements, whereas the tracked rat is represented to the human in the virtual reality by a humanoid avatar. We describe the system and also a study that was designed to test whether humans can successfully play a game with the rat. The results show that the system functioned well and that the humans were able to interact with the rat to fulfil the tasks of the game. This system opens up the possibility of new applications in the life sciences involving participant observation of and interaction with animals but at human scale.

The contribution of real-time mirror reflections of motor actions on virtual body ownership in an immersive virtual environment

This paper reports an experiment that investigated people"s body ownership of an avatar that was observed in a virtual mirror. Twenty subjects were recruited in a within-groups study where 10 first experienced a virtual character that synchronously reflected their upper-body movements as seen in a virtual mirror, and then an asynchronous condition where the mirror avatar displayed prerecorded actions, unrelated to those of the participant. The other 10 subjects experienced the conditions in the opposite order. In both conditions the participant could carry out actions that led to elevation above ground level, as seen from their first person perspective and correspondingly in the mirror. A rotating virtual fan eventually descended to 2m above the ground. The hypothesis was that synchronous mirror reflection would result in higher subjective sense of ownership. A questionnaire analysis showed that the body ownership illusion was significantly greater for thesynchronous than asynchronous condition. Additionally participants in the synchronous condition avoided collision with the descending fan significantly more often than those in the asynchronous condition. The results of this experiment are put into context within similar experiments on multisensory correlation and body ownership within cognitive neuroscience.

Mística i espiritisme: la fascinació per l’altra riba. Amàlia Domingo Soler i Eulàlia Anzizu i Vila

Les escriptores Amàlia Domingo Soler (1835-1909) i Eulàlia Anzizu i Vila (1868-1916) no es van conèixer mai, i probablement des de les pròpies posicions ideològiques —lliurepensadora, una; monja clarissa, l’altra— ni tan sols haurien pogut coincidir enlloc. Compartien, però, la mateixa ciutat, Barcelona, i una mateixa època convulsa —la segona meitat del segle XIX i els inicis del XX—, així com alguns trets de la personalitat: eren dones autodidactes, intel·lectuals geloses de la seva independència i de les seves conviccions i, sobretot, mostraven idèntica passió per l’escriptura. Ultra les asimetries ideològiques que es donaren entre Amàlia Domingo i Eulàlia Anzizu, un conjunt d’empaties vitals en canvi, les acostava: Amàlia, l’espiritista, sentia tanta estranyesa davant la realitat com Eulàlia, la poeta mística; de la mateixa manera, hi havia en elles el mateix sentiment d’exclusió, homònima sensació de pertànyer fora del centre de la quotidianitat. Tant l’una com l’altra entengueren la terra com un desert i es forjaren un llenguatge de proximitat amb l’inconegut, tan religiós com còsmic. I l’estremiment que els produïa l’immaterial, el més enllà, impregnà de ple, i en tots dos casos, l’obra literària des de la joventut.

Control de respiració en temps real per dispositius Android

El projecte està basat en la creació d'una aplicació per dispositius mòbils android i que fent servir l'ús del micròfon capturi el so que genera l'usuari i pugui determinar si s'està respirant i en quin punt de la respiració es troba l'usuari. S'ha dut a terme una filosofia de disseny orientada a l'usuari (DCU) de manera que el primer pas ha sigut realitzar un prototip i un 'sketch'. A continuació, s'han realitzat 10 aplicacions test i en cadascuna d'elles s'ha ampliat la funcionalitat fins a arribar a obtenir una aplicació base que s'aproxima al disseny inicial generat per mitjà del prototip. El més important dels dissenys algorísmics que s'han realitzat per la aplicació es la capacitat de processar el senyal en temps real, ja que fins i tot s'ha pogut aplicar la transformada ràpida de Fourier (FFT) en temps real sense que el rendiment de l'aplicació es veies afectat. Això ha sigut possible gràcies al disseny del processament amb doble buffer i amb un fil d'execució dedicat independent del fil principal d'execució del programa 'UI Thread'

L'Anatomia artística a l"Escola de Belles Arts de Barcelona. Els casos de Jeroni Faraudo (1823-1886) i de Tiberio Ávila (1843-1932)

[cat] Aquest article se centra en la significació i transcendència de l"assignatura d"Anatomia artística a l"Escola de Belles Arts de Barcelona durant la segona meitat del segle XIX i principis de segle XX. S"empren, com a fil conductor, les figures de Jeroni Faraudo i Condeminas (1823-1886) i de Tiberio Ávila Rodríguez (1843-1932), els dos primers professors que impartiren la matèria i que romanen, en l"actualitat, pràcticament inèdits. El coneixement de l"ideari de Faraudo i d"Ávila permet completar el panorama de l"evolució de les idees estètiques a la Catalunya del moment i, alhora, contribueix a la comprensió de l"erosió de la primacia de l"antic en l"aprenentatge oficial de les arts a Catalunya.

The connecting thread of this article are Jeroni Faraudo i Condeminas (1823-1886) and Tiberio Ávila Rodríguez (1843-1932), its first two teachers, who remain nowadays practically unknown. The knowledge of their ideas completes the history of contemporary Catalan aesthetics and also contributes to the comprehension of the erosion in the primacy of the use of ancient models in the official artistic teaching in Catalonia.

Passport to a profession in the degree of pharmacy: how to integrate university students into the real world of work: "Passport to a profession in Pharmacy"

The incorporation of the Spanish university system into the European Higher Education Areahas brought about a series of adaptations. Among the recommendations is the inclusion ofan external training period in a company, which has resulted in significant changes in thedegree syllabus in order to balance the theoretical and practical education required by thestudents. This new framework has been legally confirmed by the Spanish Government and, inthe case of the University of Barcelona, by the publication of internal guidelines. Takingadvantage of this new opportunity to adapt the Pharmacy degree to real-world problems inindustry, the Dean’s team of the Faculty of Pharmacy, with the support of the Facultyadministrative staff and the Students Advisory Service, have assumed the challenge ofincluding a new subject in the syllabus entitled Training in Companies.In parallel, a new activity has been set up to ensure that the students choose the mostsuitable company department/job for them and to help them pass the company interview.Under the name of Passport to a Profession, a series of ten explanatory talks has beenscheduled every academic year. These talks deal with a broad range of topics aimed atproviding the students with the basic tools they will need to make the most of a companytraining period and to make headway in the professional world when they finish theirdegree. In addition, three Faculty of Pharmacy-Pharmaceutical company workshops and tworound-table conferences have been held in the last two years in order to bring the universityand industry together. Notably, the project to provide students with company training isexpanding on an international level, with two to three undergraduate students contractedevery year by a United Kingdom-based multinational pharmaceutical company.The statistical data of the whole process has been analysed for a more in-depthunderstanding of the activity and to improve the programme.

“Of Spitzenkandidaten and European Leaders”: Is the new 2014 "politicized” Presidency of the Commission going to be a real step forward in the EU legitimization process?

Thanks to ART.17.7 of the Lisbon Treaty, the European Council now has to “take into account” the results of EP Elections when selecting a candidate for the role of Commission President. The European Parliament has grabbed the opportunity to launch the first electoral race for spitzenkandidaten to the Presidency. Is this the start of a new democratizing (and thus, politicizing) process for the European Union? This dissertation will try to give a possible answer to the dilemma by constructing a comprehensive framework around EP Elections 2014 that will involve both the Commission and the Parliament and an analysis of the debate beyond legal provisions and the possibility of a politicized presidency of the Commission.

Les inscripcions de la plaça de la Vila de Madrid

Les conclusions que de l’estudi epigràfic se'n poden treure són coincidents amb les que ens aporten les dades de les excavacions arqueològiques. En primer lloc, podem comprovar una utilització de l’àrea com a espai funerari des de l’inici de la colònia de Barcino, amb una continuïtat i, a vegades, superposició de tombes, que arriba fins a ben entrat el segle III dC. Lògicament, la fase que se'ns mostra més potent és la més recent, que arrenca de les darreries del segle II dC per entrar en el III. Tret dels testimonis inicials, que ens fan conèixer fins i tot magistrats de la ciutat, el gruix dels documents correspon a monuments funeraris de les classes menys privilegiades, lliberts i esclaus que, de vegades, ens manifesten una entranyable vessant humana d’afectuoses relacions, en què sovintegen els diminutius. A vegades, l’estatus dels personatges és obertament declarat; en d’altres el deduïm dels termes de parentiu amb una onomàstica que acostuma a ser també ben transparent.
