150 years of the discovery of the Cambrian Lagerstätte of Murero (Cadenas Ibéricas, NE Spain)
2013
El yacimiento paleontológico del Cámbrico inferior-medio de Murero (Cadenas Ibéricas, NE de España) es una localidad clásica del Cámbrico europeo. Fue dado a conocer a la ciencia por Edouard de Verneuil en 1862, celebrándose en 2012 el 150 aniversario de su descubrimiento. Es un siglo y medio de trabajos geológicos y de logros puestos al servicio del conocimiento del Período Cámbrico. Murero es un Lagerstätte excepcional porque coexisten en él grupos esqueléticos y de cuerpo blando a lo largo de un registro estratigráfico continuo que abarca unos 8 millones de años, dividido en 14 zonas de trilobites. En 1997, este yacimiento paleontológico fue el primero de España en obtener de la Administ…
A performative approach to wool felting : Rhizomatic relations in visual arts making and art education
2023
As the first combined dissertation in Fine Arts with the specialisation Arts in context submitted to the University of Agder, comprising artistic and scientific works, this research evolves between artistic and written acts. It is a performative exploration of a performative approach to the ancestral technique of wool felting. The dissertation includes six explorations: three public exhibitions, three articles, and a 7th element consisting of a series of ongoing ‘minor’ moments related to the topic of the thesis that I carry out in my everyday practices as an artist, teacher and researcher. Alongside with that, I provide a mantle that is a metatext of the dissertation. In dialogue with the …

Oxidation, efflux, and isotopic fractionation of methane during autumnal turnover in a polyhumic, boreal lake
2007
[1] We studied the oxidation and efflux of methane (CH4) in a small, polyhumic lake, Mekkojarvi (southern Finland), during 6 weeks in autumn when the stability of the water mass first weakened, temporarily restabilized, and finally mixed completely. During the summer stratification period, CH4 had accumulated in the anoxic hypolimnion to high concentrations (>150 mmol m−3). Gradual mixing of the water column during the autumn allowed access to both oxygen and CH4 by aerobic methane-oxidizing bacteria (MOB) deeper in the water column. Thus the bulk (∼83–88%) of the CH4 accumulated in the hypolimnion was subsequently consumed by MOB while only 12–17% was lost from the lake to the atmosphere a…
Mechanism of anionic polymerization of methyl methacrylate in the presence of aluminium alkyls
1995
Methyl methacrylate was polymerized with tert-butyl lithium in the presence of triethylaluminium or triisobutylaluminium at 78°C in toluene. As indicated by GPC and MALDI-TOF mass spectrometry, the polymerization is accompanied by side reactions. The lower oligomers were fractionated by distillation and characterised by NMR, FT-IR, UV and electron impact (EI) mass spectrometry. All these data show that part of the polymer chains are carrying exactly one tert-butyl isoprenyl ketone unit. In order to avoid the formation of tert-butyl isoprenyl ketone a molar ratio of Al/Li>2 is necessary.
Molecular surveillance of norovirus, 2005–16 : an epidemiological analysis of data collected from the NoroNet network
2018
BACKGROUND: The development of a vaccine for norovirus requires a detailed understanding of global genetic diversity of noroviruses. We analysed their epidemiology and diversity using surveillance data from the NoroNet network.METHODS: We included genetic sequences of norovirus specimens obtained from outbreak investigations and sporadic gastroenteritis cases between 2005 and 2016 in Europe, Asia, Oceania, and Africa. We genotyped norovirus sequences and analysed sequences that overlapped at open reading frame (ORF) 1 and ORF2. Additionally, we assessed the sampling date and country of origin of the first reported sequence to assess when and where novel drift variants originated.FINDINGS: W…
Latvia. Human Development Report 2008/2009. Accountability and Responsibility
2009
Accountability and Responsibility. The objetive of the 2008/2009 Human Development Report was to examine different levels of accountability and the specific way in which accountability is manifested in Latvia at individual, coolective, and institutional levels which come together to form an accountability "network". The Report also compares the situation in Latvia with that in the other Baltic States, the European Union, and elsewhere in the world.
Data from the GIPEyOP online election poll for the 2015 Spanish General election.
2020
Abstract The general elections of 2015 in Spain took place in the middle of the Great Recession after several years of austerity economic policies. This election caused a political earthquake that shook the Spanish party system. During the campaign of that election, GIPEyOP (Elections and Public Opinion Research Group from University of Valencia) conducted a survey to collect relevant data about the electorate beliefs, intentions and motivations. This article describes the data set attained, which comprises 71 variables after removing, to ensure full anonymity, those variables that would potentially allow respondents to be identified. Respondents answered a self-administered online question…
Iron operates as an important factor promoting year-round diazotrophic cyanobacteria blooms in eutrophic reservoirs in the tropics
2021
Abstract We hypothesize that iron availability plays an important role in driving phytoplankton structure and dynamics in tropical reservoir. This role has often been neglected in routine monitoring of water quality since the main focus has been addressed on macronutrients such phosphorus and nitrogen. To elucidate the potential regulation exerted by iron availability on phytoplankton, a limnological investigation was carried out in two neighboring eutrophic reservoirs in tropical China. Traditional physical and chemical variables were measured along with total and dissolved iron concentrations to explore how they could influence phytoplankton structure. Statistical analyses showed that dis…
Duplicated cytoglobin genes in teleost fishes
2005
Cytoglobin is a recently discovered myoglobin-related O2-binding protein of vertebrates with uncertain function. It occurs as single-copy gene in mammals. Here, we demonstrate the presence of two paralogous cytoglobin genes (Cygb-1 and Cygb-2) in the teleost fishes Danio rerio, Oryzias latipes, Tetraodon nigroviridis, and Takifugu rubripes. The globin-typical introns at positions B12.2 and G7.0 are conserved in both genes, whereas the C-terminal exon found in mammalian cytoglobin is absent in the fish genes. Phylogenetic analyses show that the two cytoglobin genes diverged early in teleost evolution. This is confirmed by gene synteny analyses, which suggest a large-scale duplication event. …
