El aprendizaje servicio como propuesta metodológica para una pedagogía crítica
2016
El presente artículo aborda la relación entre la pedagogía crítica y los pilaresfundamentales de la metodología del aprendizaje servicio. Su principal objetivo esdemostrar, de un modo concluyente, la idoneidad del aprendizaje servicio comometodología para alcanzar objetivos pedagógicos tales como la emancipación, latransformación y la justicia social. El trabajo parte de la clarificación de los pilaresfundamentales de la pedagogía crítica, entendida como paradigma filosófico-educativoque emerge de la Teoría Crítica de la Escuela de Frankfurt. Posteriormente, el artículoda cuenta de los fundamentos pedagógicos del aprendizaje servicio, aportandoargumentos que evidencian su capacidad para sat…
Voltammetric behavior of berenil.
1993
Abstract Berenil is reduced on mercury drops electrode in buffered aqueous media. The reduction of —N=N— group is controlled by diffusion. Polarographie waves are of analytical usefulness. The hydrogen discharge is favored by the basic centers of the molecule in Co(ll)/ammonia-buffered media.
Ionic liquids versus amine solutions in biogas upgrading: the level of volatile organic compounds
2013
Background: This article provides information related to the occurrence of volatile organic compounds before and after biogas purification, by means of both aqueous amine solutions and ionic liquids. Results & discussion: Encouraging results were obtained. Under the experimental conditions, 1-butyl-3-methylimidazolium acetate ionic liquid appeared to perform at least two-times better than aqueous amines solutions, since it captured 65 wt% of the identified volatile organic compounds, while aqueous amine solutions retained around 35 wt% only. However, in the case of octamethylcyclotetrasiloxane and dichlorobenzene, aqueous amine solutions rendered better purification performance and diminish…

Art-based social and educational action in Barcelona
2018
Des de fa uns anys, a Barcelona hi ha tot un moviment d’acció educativa que neix des de les arts i que fomenta la participació ciutadana en base a la cohesió social. Les noves propostes de l’educació artística tenen una forta component social, ja que impulsen la participació, tot redefinint els conceptes tradicionals de l’educació en arts. Hem entrevistat alguns dels promotors d’aquestes iniciatives per indagar en els models d’activitats i en les formes d’organització que representen. Hem descobert les problemàtiques que afecten a aquest model organitzatiu (precarietat, dependència institucional, canvis constants, atenció a tot tipus de públics), però també hem descobert els avantatges de g…
Horyzontalny skutek bezpośredni obowiązku zawieszenia udzielania pomocy na podstawie art. 108 ust. 3 zd. 3 TFUE
2021
Niniejsza praca odnosi się do zagadnienia skutku bezpośredniego klauzuli zawieszenia (art. 108 ust. 3 zd. 3 TFUE), mającej zastosowanie do odzyskania pomocy niezgodnej z prawem bez konieczności istnienia decyzji Komisji, wskazując, że niedawny rozwój orzecznictwa wskazuje na jej skutek horyzontalny. Nadto sytuacja beneficjenta jest poddawana ocenie z wnioskiem, że ów nie posiada podobnej pozycji procesowej, co osoba powołująca się na art. 108 ust. 3 zd. 3 TFUE. Praca odnosi się do stanu prawnego z 1.04.2021 r.
Emerging brominated flame retardants and dechlorane-related compounds in European eels (Anguilla anguilla) from Latvian lakes
2017
Abstract Fifteen halogenated flame retardants (HFRs) including seven emerging brominated flame retardants (EBFRs) and eight dechlorane-related compounds (DRCs) were analyzed in eels (Anguilla anguilla) sampled from five Latvian lakes. Out of the seven EBFRs, hexabromocyclododecane (HBCD) and decabromodiphenyl ethane (DBDPE) were found in eels in quantifiable concentrations, up to 6.58 and 33.0 ng g−1 lipid weight (l.w.), respectively. The mean total concentration of DRCs (∑DRC) in the samples was 0.62 ng g−1 l.w. and the geographical distribution of DRC contamination was nearly uniform among the selected lakes. Dechlorane 602 (Dec 602) was the predominant component, whereas the composition …
Philae's first days on the comet
2015
On 12 November 2014, Philae landed on the surface of comet 67P/Churyumov-Gerasimenko (67P), making an almost 30-year dream a reality. The pioneering flybys of 1P/Halley in 1986 revealed that despite being made primarily of ice, it was covered in highly absorbing carbonrich molecules. What is their composition? When did they form, and through which chemical routes? Might they have constituted prebiotic molecules necessary for life? At a larger scale, what can one learn from comets that has relevance to the evolution of the solar system and planets? ![Figure][1] 12 NOVEMBER 2014: PHILAE LANDED ON THE NUCLEUS OF COMET 67P CREDIT: ESA/ROSETTA/MPS FOR OSIRIS TEAM MPS/UPD/LAM/IAA/SSO/INTA/UPM/DAS…
Reconstruction of inclined air showers detected with the Pierre Auger Observatory
2014
We describe the method devised to reconstruct inclined cosmic-ray air showers with zenith angles greater than $60^\circ$ detected with the surface array of the Pierre Auger Observatory. The measured signals at the ground level are fitted to muon density distributions predicted with atmospheric cascade models to obtain the relative shower size as an overall normalization parameter. The method is evaluated using simulated showers to test its performance. The energy of the cosmic rays is calibrated using a sub-sample of events reconstructed with both the fluorescence and surface array techniques. The reconstruction method described here provides the basis of complementary analyses including an…
Muons in air showers at the Pierre Auger Observatory: Measurement of atmospheric production depth
2014
The surface detector array of the Pierre Auger Observatory provides information about the longitudinal development of the muonic component of extensive air showers. Using the timing information from the flash analog-to-digital converter traces of surface detectors far from the shower core, it is possible to reconstruct a muon production depth distribution. We characterize the goodness of this reconstruction for zenith angles around 60° and different energies of the primary particle. From these distributions, we define Xμmax as the depth along the shower axis where the production of muons reaches maximum. We explore the potentiality of Xμmax as a useful observable to infer the mass compositi…
