The appearance and popularization of the internet has created new forms of writing, which compel us to think anew about identity and subjectivity. Webjournals or blogs are specially interesting because they are a massive phenomenon that use autobiographical writing in a peculiar way. These forms of writing stress a particular paradox of the genre: the coexistence between a purpose of private, confessional and spontaneous writing and a public image, carefully built, as a result of its writing. The technology is new, but, in fact, the paradox is old. This paper tries to explore this old paradox, our eternal condition of cyborgs, our use of technologies in order to construct a public, unique and recognizably identity. In oder to do so, I will try to show the virtual condition of any written individual ¿this issue has already been dealt with by autobiographical studies¿, focusing on blogs, and especially on concrete example (Lord Whimsy¿s Journal). I will pay attention to gender as a technology that constructs identity and, at the same time, is deconstructed by the autobiographical narratives analyzed. In short, I attempt to show that virtual and autobiographical discourse do not bring forth a new kind of subject but the permanence of an old phenomenon "clearly developed by dandyism, for instance¿: the use of tehnologies to re-invent, re-formulate and re-construct us as multiple, hybrid and mixed subjects."

El texto que sigue resulta de una re-construcción de cuatro aproximaciones -biomédica-evolutiva, crítica, hermenéutico-construccionista y post-estructural- a la educación en medios con jóvenes en contextos educativos formales, entendida ésta en un sentido amplio como la enseñanza y aprendizaje de los medios de comunicación analógicos y digitales. Uno de los propósitos de la re-construcción tiene que ver, en primer lugar con la visibilización de la diversidad de opciones y epistemologías disponibles a la hora de plantear un escenario formativo en educación con medios, y con las posibilidades formativas que dicha multiplicidad nos ofrece...

Listeria monocytogenes was inoculated on the surface of sliced fermented sausages with no added sodium salt. The pathogen was progressively inactivated during the product shelf life (90 days). Antimicrobial packaging of fermented sausages with PVOH films containing nisin induced a more pronounced reduction of L. monocytogenes counts during refrigerated storage. HPP alone (600 MPa, 5 min, 12 °C) had no antimicrobial effect against L. monocytogenes at the studied conditions. Combination of HPP with antimicrobial packaging did not produce any extra protection against L. monocytogenes compared to antimicrobial packaging alone. The lack of effect of HPP on L. monocytogenes was attributed to a protective effect exerted by the low water activity of the product and its lactate content. These results reflect that antimicrobial packaging with the inclusion of nisin as a natural antimicrobial could be considered as an effective method to reduce the levels of L. monocytogenes in sliced fermented sausages with no added sodium salt

El dolor post-operatori és un dels problemes més importants que segons la OMS afecta als pacients intervinguts quirúrgicament i el que més els preocupa. Any rere any hi ha un increment del nombre de pacients intervinguts per Cirurgia Major ambulatòria al nostre país de manera que ha de ser el mateix usuari i la família els que facilitin les cures als pacients al propi domicili. Aquest estudi planteja si introduir intervencions educatives al servei disminueix el dolor post-operatori dels usuaris Objectiu general: Dissenyar un programa d’informació que realitzarà infermeria dirigit als cuidadors i pacients del servei de CMA i que han de ser intervinguts de hèrnia engonal. Avaluar l’eficiència del mateix programa educatiu. Metodologia: l’àmbit d’estudi d’aquest treball serà les unitats de Cirurgia Major ambulatòria de qualsevol centre de Catalunya. Es realitzarà un estudi comparatiu quantitatiu entre dos grups independents integrants per 30 participants en cadascun d’ells (total de 60 participants). Grupo A: protocol habitual de la unitat Grup B: intervenció educativa dissenyada Els participants seran pacients majors d’edat, que compleixen els requisits per ser intervinguts per Cirurgia Major Ambulatòria de Hèrnia inguinal. El participant ha de fer-ho amb un familiar responsable de les seves cures. Es realitzaran 3 enquestes al pacient i 3 al familiar responsable de les cures, la primera a les 24 hores després de la intervenció, la segona a la setmana i l’última a les 2 setmanes. Limitacions de l’estudi: en cas de que el pacient que ha de formar part de l’estudi requereixi ingrés hospitalari per alguna complicació durant la cirurgia el pacient deixa de participar en l’estudi automàticament. En cas que el pacient o familiar no contestin al telèfon el dia i l’hora pactada prèviament també deixarà de formar part de la investigació. Per aquest motiu es tindran 10 pacients de reserva per si calgués reemplaçar el subjecte d’estudi.

Although sources in general nonlinear mixturm arc not separable iising only statistical independence, a special and realistic case of nonlinear mixtnres, the post nonlinear (PNL) mixture is separable choosing a suited separating system. Then, a natural approach is based on the estimation of tho separating Bystem parameters by minimizing an indcpendence criterion, like estimated mwce mutual information. This class of methods requires higher (than 2) order statistics, and cannot separate Gaarsian sources. However, use of [weak) prior, like source temporal correlation or nonstationarity, leads to other source separation Jgw rithms, which are able to separate Gaussian sourra, and can even, for a few of them, works with second-order statistics. Recently, modeling time correlated s011rces by Markov models, we propose vcry efficient algorithms hmed on minimization of the conditional mutual information. Currently, using the prior of temporally correlated sources, we investigate the fesihility of inverting PNL mixtures with non-bijectiw non-liacarities, like quadratic functions. In this paper, we review the main ICA and BSS results for riunlinear mixtures, present PNL models and algorithms, and finish with advanced resutts using temporally correlated snu~sm

Further knowledge of the processes conditioning nitrogen use efficiency (NUE) is of great relevance to crop productivity. The aim of this paper was characterise C and N partitioning during grain filling and their implications for NUE. Cereals such as bread wheat (Triticum aestivum L. cv Califa sur), triticale (× Triticosecale Wittmack cv. Imperioso) and tritordeum (× Tritordeum Asch. & Graebn line HT 621) were grown under low (LN, 5 mm NH4NO3) and high (HN, 15 mm NH4NO3) N conditions. We conducted simultaneous double labelling (12CO2 and 15NH415NO3) in order to characterise C and N partitioning during grain filling. Although triticale plants showed the largest total and ear dry matter values in HN conditions, the large investment in shoot and root biomass negatively affected ear NUE. Tritordeum was the only genotype that increased NUE in both N treatments (NUEtotal), whereas in wheat, no significant effect was detected. N labelling revealed that N fertilisation during post-anthesis was more relevant for wheat and tritordeum grain filling than for triticale. The study also revealed that the investments of C and N in flag leaves and shoots, together with the"waste" of photoassimilates in respiration, conditioned the NUE of plants, and especially under LN. These results suggest that C and N use by these plants needs to be improved in order to increase ear C and N sinks, especially under LN. It is also remarkable that even though tritordeum shows the largest increase in NUE, the low yield of this cereal limits its agronomic value.

Aquest treball proposa un estudi del recull de contes de Jordi Puntí, Animals tristos, des d'una directriu bàsica: el plantejament teòric sobre la fragilitat dels vincles humans de la postmodernitat postulat pel sociòleg Zygmunt Bauman en la seva obra Amor líquido. Acerca de la fragilidad de los vínculos humanos. Així, l'objectiu de l'estudi és demostrar que els personatges d'Animals tristos són un reflex de la societat urbana actual i de la naturalesa canviant en les relacions de parella de principis del s. XXI que descriu Bauman. D'aquesta forma, l'anàlisi de l'obra de Puntí, especialment dels seus personatges, és realitzada a través d'un marc teòric de naturalesa sociològica.

The presence of hydrogen in polysilicon films obtained at low temperatures by hot-wire CVD and the post-deposition oxidation by air-exposure of the films are studied in this paper. The experimental results from several characterization techniques (infrared spectroscopy, X-ray photoelectron spectroscopy, secondary ion mass spectrometry and wavelength dispersive spectroscopy) showed that hydrogen and oxygen are homogeneously distributed at grain boundaries throughout the depth of the films. Hydrogen is introduced during the growth process and its concentration is higher in samples deposited at lower temperatures. Oxygen diffuses along the grain boundaries and binds to silicon atoms, mainly in Si 2O groups.

En el presente trabajo se analiza el origen del almudí de Lérida –mercado de granos de la ciudad, su funcionamiento y su papel en el territorio. En base a la mercurial de Lérida, hemos elaborado una nueva serie de los precios del trigo siguiendo el año agrícola y utilizando cinco mercados, uno por semana. Finalmente, se presenta un primer estudio comparativo para el periodo 1757/58-1807/08 entre estos precios de Lérida y los de Barcelona, elaborados con la misma metodología. Las fuentes principales son los registros de precios y las actas del ayuntamiento de Lérida. Los precios del almudí serán un referente para el conjunto de la Cataluña occidental y el Aragón oriental. A pesar de que el mercado de Lérida está poco regulado, en los momentos de crisis de la segunda mitad del siglo XVIII y en el primer tercio de la siguiente centuria, la municipalidad realiza diversas acciones a favor de los vecinos más necesitados. Estas iniciativas nos remiten a la economía moral. Si bien los nuevos precios de Lérida son, en general, muy similares a los equivalentes realizados con el mercado central del mes, las diferencias son muy significativas para determinados momentos críticos. Este hecho confirma la necesidad de elaborar precios de mayor calidad para los diferentes mercados catalanes y españoles. Finalmente, la comparación de los precios de Lérida y Barcelona del período 1777/78-1807/08 con 1757/58-1776/77, permite confirmar que las coyunturas críticas del último tercio del siglo XVIII y comienzos del siglo XIX provocan respuestas de los diferentes agentes económicos de la Cataluña occidental que retrasan temporalmente la transferencia de la información que reflejan los precios de Barcelona a los precios del almudí de Lérida.

Actualmente se estudian diversos métodos alternativos a los procedimientos habituales de control de plagas y enfermedades de la fruta en post-cosecha, algunos de los cuales se utilizan ya a nivel comercial, como el empleo de microorganismos antagónicos, método en el que se centra el presente artículo. La fruta almacenada en cámaras frigoríficas supone una buena oportunidad para emplear sistemas de lucha biológica en el control de las enfermedades de post-cosecha, puesto que la fruta se encuentra bajo condiciones ambientales controladas, tanto de humedad relativa y temperatura como por la concentración de gases.

En el present treball analitzarem el pensament, actituds i valors del grup dominant liberal en la ciutat de Lleida durant l'època isabelina (1833-1868). El nostre propòsit serà el d’intentar superar les evidents diferències ideològiques que havia entre els seus membres (principalment les polítiques entre liberals moderats i progressistes) per trobar els valors bàsics acceptats en el comportament social dominant en la Lleida de mitjan segle XIX. D'aquesta manera, delimitant aquesta actitud col·lectiva intentarem arribar a la mentalitat de la comunitat al voltant de les seves costums.

La consecuencia lógica de la integración de las personas con necesidades educativas especiales en la institución escolar tendría que ser la anexión de estas a ámbitos normalizados de su colectividad una vez finalizada la escolaridad obligatoria. El discurso de la integración, por tanto, no se tendría que situar única y exclusivamente en el ámbito escolar, sino que debería extrapolarse a todos los ámbitos donde la persona se desarrolla. En este trabajo analizamos los itinerarios escolares y post-escolares que siguen las personas con discapacidad psíquica en la comarca del Segrià (Cataluña), apuntamos las posibles causas por las que se configuran unos itinerarios u otros y, a partir de ahí, establecemos pautas de reflexión para ir construyendo una escuela y una sociedad para todos.

The Spanish Government has established post-market environmental monitoring (PMEM) as mandatory for genetically modified (GM) crop varieties cultivated in Spain. In order to comply with this regulation, effects of Bt maize varieties derived from the event MON810 on the predatory fauna were monitored for two years in northeast and central Spain. The study was carried out with a randomized block design in maize fields of 3-4 ha on which the abundance of plant-dwelling predators and the activity-density of soil-dwelling predators in Bt vs. non-Bt near-isogenic varieties were compared. To this end, the plots were sampled by visual inspection of a certain number of plants and pitfall traps 6 or 7 times throughout two seasons. No significant differences in predator densities on plants were found between Bt and non-Bt varieties. In the pitfall traps, significant differences between the two types of maize were found only in Staphylinidae, in which trap catches in non-Bt maize were higher than in Bt maize in central Spain. Based on the statistical power of the assays, surrogate arthropods for PMEM purposes are proposed; Orius spp. and Araneae for visual sampling and Carabidae, Araneae, and Staphylinidae for pitfall trapping. The other predator groups recorded in the study, Nabis sp. and Coccinellidae in visual sampling and Dermaptera in pitfall trapping, gave very poor power results. To help to establish a standardized protocol for PMEM of genetically modified crops, the effect-detecting capacity with a power of 0.8 of each predator group is given.
