In the context of lay mobilization in health-related areas, this article addresses the role and activities of patients' associations in connection with organ donation, on the basis of interviews carried out with thirty members of transplant patients' associations in the French-speaking part of Switzerland. First, we describe the three main categories of activities conducted by these associations. While self-help and public awareness activities are predominant, policy-oriented actions are marginal. Then, we examine the factors likely to explain why these associations have a limited capacity to be active, especially in the public sphere. Such a lack of social visibility is all the more important in the current political context, characterized by the implementation of a national action plan designed to improve organ donation.

Les pràctiques educatives que es basen en una metodologia on s’integren les noves Tecnologies de la Informació i la Comunicació (TIC) són cada cop més influents en l’àmbit educatiu, ja que, ens acosten a la realitat de l’època en què vivim, la societat de la informació i l’alfabetització digital. Així, en aquest estudi s’investiga la motivació i l’adquisició de l’hàbit lector a través dels codis QR en un grup d’infants d’edats compreses entre cinc i sis anys d’Educació Infantil. A partir dels instruments de recollida de dades, com ara, l’entrevista, l’observació, els qüestionaris i la pròpia intervenció educativa, podem saber que la motivació de llegir contes i d’utilitzar les noves tecnologies augmenta en l’actitud dels infants. Pel que fa a l’aprenentatge i adquisició de l’hàbit lector, arribem a la conclusió que és un procés llarg i, segons l’entorn que té l’infant, hi influeix de manera positiva o negativa.

This article aims to explain how newspapers commented on the movie Good Night, and Good Luck before its release. The media coverage anticipated George Clooney's film as a partisan attack launched against George W. Bush's policy since 9/11. Clooney advocates another reading: the historic confrontation between journalist Edward Murrow and Senator Joseph McCarty permits to reflect on the crucial role that the media play for democracy. Such reflection tries to prevent the dividing of the public sphere into antagonistic camps opposing "friends" to "foes," a division that undermines the possibility of a true pluralism. Our socio-semiotic analysis will focus on the critical work accomplished by the media, and on the way that work determines the collective meaning of a cultural object. Simultaneously, we will discuss the necessary conditions for pluralism in a public sphere.

We determined if performance and mechanical running alterations during repeated treadmill sprinting differ between severely hot and hypoxic environments. Six male recreational sportsmen (team- and racket-sport background) performed five 5-s sprints with 25-s recovery on an instrumented treadmill, allowing the continuous (step-by-step) measurement of running kinetics/kinematics and spring-mass characteristics. These were randomly conducted in control (CON; 25°C/45% RH, inspired fraction of oxygen = 20.9%), hot (HOT; 38°C/21% RH, inspired fraction of oxygen = 20.9%; end-exercise core temperature: ~38.6°C) and normobaric hypoxic (HYP, 25°C/45% RH, inspired fraction of oxygen = 13.3%/simulated altitude of ~3600 m; end-exercise pulse oxygen saturation: ~84%) environments. Running distance was lower (P < 0.05) in HOT compared to CON and HYP for the first sprint but larger (P < 0.05) sprint decrement score occurred in HYP versus HOT and CON. Compared to CON, the cumulated distance covered over the five sprints was lower (P < 0.01) in HYP but not in HOT. Irrespective of the environmental condition, significant changes occurred from the first to the fifth sprint repetitions (all three conditions compounded) in selected running kinetics (mean horizontal forces, P < 0.01) or kinematics (contact and swing times, both P < 0.001; step frequency, P < 0.001) and spring-mass characteristics (vertical stiffness, P < 0.001; leg stiffness, P < 0.01). No significant interaction between sprint number and condition was found for any mechanical data. Preliminary evidence indicates that repeated-sprint ability is more impaired in hypoxia than in a hot environment, when compared to a control condition. However, as sprints are repeated, mechanical alterations appear not to be exacerbated in severe (heat, hypoxia) environmental conditions.

[spa]Las estrategias comerciales de los libreros y editores españoles para desembarcar en los mercados americanos son analizadas en un contexto signado por las tendencias americanistas en el plano político y las iniciativas regeneracionistas en el económico durante el periodo que va del Centenario de las Independencias hasta la Guerra Civil española. Se abordan algunas de las políticas empresariales editoriales implementadas en Cataluña, el liderazgo ejercido por esta región como epicentro del proyecto hispano, y finalmente las condiciones que permitieron la creación de la editorial Sudamericana en Buenos Aires ante la inminencia del triunfo franquista. Los ejes de estudio son las estrategias editoriales y comerciales; el peso de las asociaciones y corporaciones patronales del libro; y los vínculos tejidos con el sector intelectual argentino en las primeras décadas del siglo XX a través de delegaciones consulares, instituciones culturales y cámaras españolas de comercio.

Neste Oil has introduced plant oils and animal fats for the production of NExBTL renewable diesel, and these raw materials differ from the conventional mineral based oils. One subject of new raw materials study is thermal degradation, or in another name pyrolysis, of these organic oils and fats. The aim of this master’s thesis is to increase knowledge on thermal degradation of these new raw materials, and to identify possible gaseous harmful thermal degradation compounds. Another aim is to de-termine the health and environmental hazards of identified compounds. One objective is also to examine the formation possibilities of hazardous compounds in the produc-tion of NExBTL-diesel. Plant oils and animal fats consist mostly of triglycerides. Pyrolysis of triglycerides is a complex phenomenon, and many degradation products can be formed. Based on the literature studies, 13 hazardous degradation products were identified, one of which was acrolein. This compound is very toxic and dangerous to the environment. Own pyrolysis experiments were carried out with rapeseed and palm oils, and with a mix-ture of palm oil and animal fat. At least 12 hazardous compounds, including acrolein, were analysed from the gas phase. According to the experiments, the factors which influence on acrolein formation are the time of the experiment, the sphere (air/hydrogen) in which the experiment is carried out, and the characteristics of the used oil. The production of NExBTL-diesel is not based on pyrolysis. This is why thermal degradation is possible only when abnormal process conditions prevail.

Aquesta recerca té per finalitat aproximar-se a la percepció que tenen les víctimes de violència masclista del tracte que reben dels diferents operadors en seu judicial, i mostrar com aquestes actuacions les han afectat no només a nivell personal, sinó també a nivell processal. L’objectiu principal és copsar l’experiència de les dones víctimes de violència de gènere en referència al seu pas pels jutjats especialitzats de Catalunya. Per la consecució de l’objectiu s’ha treballat, d’una banda, amb la revisió i actualització teòrica i contextual del tema d’investigació i, per l’altra i principalment, amb la realització de més de 40 entrevistes als diferents operadors judicials i a dones víctimes de violència masclista i a entitats que treballen amb elles. Els resultats ens demostren que existeixen múltiples mancances en l’abordatge de la violència masclista als jutjats, que es reflecteixen en temes com: la manca d’informació, la valoració del risc, l’existència de mites i prejudicis vers les dones, la manca de formació, ... Aquestes mancances són generadores de l’anomenada victimització secundària. La situació descrita posa de manifest la necessitat de fer un veritable abordatge dels problemes detectats per tal de fer realment efectiva i eficient la lluita contra la violència masclista sobre les dones a seu judicial.

Anion adsorption/desorption dynamics was studied as individual processes on surface of particles of a gibbsitic clay. The data suggest a remarkable gibbsite role as nitrate leaching retardant in soil. The opposite behavior of gibbsite towards adsorption/desorption of silicate and phosphate suggests the need of an adequate compromise solution regarding interval and rate applications of anions in cultivated gibbsitic soils. The high P adsorption verified in pH values lower than that reported for the point of zero charge of synthetic Al-hydroxides implies that this process takes place in pedogenic gibbsites through inner sphere complexation.

The electrochemical properties of micro and nano-electrodes are widely investigated due to their low faradaic and capacitive currents, leading to a new generation of smart and implantable devices. However, the current signals obtained in low-dimensional devices are strongly influenced by noise sources. In this paper, we show the evaluation of filters based on Fast Fourier Transform (FFT) and their implementation in a graphical user interface (GUI) in MATLAB®. As a case study, we evaluated an electrochemical reaction process of charge transfer via outer-sphere. Results showed successful removal of most of the noise in signals, thus proving a promising tool for low-scale measurement.

Tuotantostrategisia päätöksiä, tässä tutkimuksessa erityisesti ulkoistamis-, verkostoitumis- ja ulkomaille laajentamispäätöksiä, tehdään yrityksissä jatkuvasti nykyisessä dynaamisessa liiketoimintaympäristössä. Tuotantostrategisen päätöksenteon jäljet ovat pitkälle johtavia ja päätöksenteossa tehdyt virheet voivat siksi olla yrityksille todella haavoittavia. Tutkimuksen tavoitteena on kuvata nykyistä tuotantostrategista päätöksentekoa suomalaisissa kone- ja metalliteollisuuden pk-yrityksissä. Kirjallisuudesta ja aikaisemmista tutkimuksista muodostetaan teoriapohja tuotantostrategisesta päätöksenteosta ja tunnetuimmista päätöksentekotyökaluista. Empiirinen aineisto koostuu asiantuntija- ja yrityshaastatteluista. Sekä teoriassa että empiriassa tuotantostrategista päätöksentekoa pidetään viime kädessä ylimmän johdon osaamis- ja vastuualueena. Teoria näkee päätöksenteon koko henkilöstön sitovana prosessina, jossa apuna käytetään taloudellisten menetelmien lisäksi myös muita työkaluja. Haastattelujen perusteella päätöksentekovaiheista ei yrityksissä ole olemassa kirjallista kuvausta ja päätökset tehdään hallituksessa tai johtoryhmässä nopeasti ja pääasiassa taloudellisiin menetelmiin nojaten.

Complexes of Ni(II) 2,3-, 3,5- and 2,6-dimethoxybenzoates have been synthesized, their physico-chemical properties have been compared and the influence of the position of -OCH3 substituent on their properties investigated. The analysed compounds are crystalline, hydrated salts with green colour. The carboxylate ions show a bidentate chelating or bridging coordination modes. The thermal stabilities of Ni(II) dimethoxybenzoates were investigated in air in the range of 293-1173 K. The complexes decompose in three steps, yelding the NiO as the final product of decomposition. Their solubilities in water at 293 K are in the order of 10-2-10-4 mol×dm-3. The magnetic susceptibilities for the analysed dimethoxybenzoates of Ni(II) were measured over the range of 76-303 K and the magnetic moments were calculated. The results reveal that the complexes are the high-spin ones and the ligands form the weak electrostatic field in the octahedral coordination sphere of the central Ni(II) ion. The various position -OCH3 groups in benzene ring cause the different steric, mesomeric and inductive effects on the electron density in benzene ring.

Among the numerous approaches to food waste treatment, the food waste disposers method (FWDs), as a newcomer, has become slowly accepted by the general public owing to the worries about its impact on the existing sewage system. This paper aims to justify the role of FWDs in the process of urbanization in order to better prepare a city to take good care of the construction of its infrastructure and the solid waste treatment. Both the literatures and the case study help to confirm that FWDs has no negative effects on the wastewater treatment plant and it is also environmental friendly by reducing the greenhouse gas emissions. In the case study, the Lappeenranta waste water treatment plant has been selected in order to figure out the possible changes to a WWTP following the integration of FWDs: the observation shows only minor changes take place in a WWTP, in case of 25% application, like BOD up 7%, TSS up 6% and wastewater flowrate up 6%, an additional sludge production of 200 tons per year and the extra yield of methane up to 10000m3 per year; however, when the utilization rate of FWD is over 75%, BOD, TSS, and wastewater flowrate will experience more significant changes, thus exerting much pressure on the existing WWTP. FWDs can only be used in residential areas or cities equipped with consummate drainage network within the service sphere of WWTP, therefore, the relevant authority or government department should regulate the installation frequency of FWDs, while promoting the accessory application of FWDs. In the meanwhile, WWTP should improve their treatment process in order to expand their capacity for sludge treatment so as to stay in line with the future development of urban waste management.
