Table 2: List of UV fluxes for the sample of AGN and references.
Table 3: Chemical abundances estimated from HCm-UV, using the grid of AGN
models for alpha(OX) = -1.2 and the stopping criteria of 98% of free
electrons. Dust-free or grain-included models are selected based on their C3C4
value., We present an adapted version of the code HII-CHI-mistry-UV (Perez-Montero &
Amorin 2017) to derive chemical abundances from emission lines in the
ultraviolet, for use in narrow line regions (NLR) of Active Galactic Nuclei
(AGN). We evaluate different ultraviolet emission line ratios and how
different assumptions about the models, including the presence of dust
grains, the shape of the incident spectral energy distribution, or the
thickness of the gas envelope around the central source, may affect the final
estimates as a function of the set of emission lines used. We compare our
results with other published recipes for deriving abundances using the same
emission lines and show that deriving the carbon-to-oxygen abundance ratio
using C iii] λ 1909 Å and O iii] λ 1665 Å emission lines is a robust indicator
of the metal content in AGN that is nearly independent of model assumptions,
similar to the case of star-forming regions. Moreover, we show that a prior
determination of C/O allows for a much more precise determination of the total
oxygen abundance using carbon UV lines, as op- posed to assuming an arbitrary
relationship between O/H and C/O, which can lead to non-negligible
discrepancies., This work has been partly funded by projects Estallidos7 PID2019-107408GB-C44 (Spanish Ministerio de Ciencia e Innovacion), and the Junta de Andalucia for grant EXC/2011 FQM-7058.

[Descripción de los métodos utilizados para la recopilación/generación de datos] La evaluación de La Noche de l@s Investigador@s por parte de sus protagonistas se ha realizado a partir de tres cuestionarios online habilitados en la web nocheinvestiga.es adaptados a tres perfiles diferentes: 1) investigadores/as, 2) asistentes y 3) menores de 18 años. La aplicación de encuestas online ha sido desarrollada íntegramente por IESA CSIC sin apoyo de ningún software comercial, garantizando de este modo la privacidad, seguridad y calidad de los datos. El trabajo de campo se realizó entre el 23 de noviembre y el 20 de diciembre de 2020. La crisis sobrevenida ha implicado cambios y adaptaciones importantes. La realización online de la práctica totalidad de las actividades ha determinado cambios en la metodología de evaluación prevista, adaptándola a esta situación condicionante. Así, la evaluación dirigida a los asistentes se ha realizado totalmente online, en parte cumplimentando el cuestionario tras la realización de la actividad y en parte tras invitación dirigida al correo electrónico suministrado por el participante en el momento de inscribirse en la misma, en las actividades que así lo requerían. La evaluación dirigida a investigador@s y organizador@s se ha realizado igualmente online, tras invitación mediante correo electrónico. Por otro lado, en esta edición se ha optado por administrar un cuestionario específico a los y las participantes menores de 18 años, con preguntas orientadas a detectar sus potenciales vocaciones científicas. Por lo tanto, se ha dispuesto de tres cuestionarios diferentes. La metodología empleada en la evaluación de La Noche de l@s investigador@s ha permitido recabar casi 1.225 cuestionarios que se distribuyen por perfiles del siguiente modo:
• Un cuestionario destinado a l@s participantes en las actividades mayores de 17 años, administrado y cumplimentado de manera online tras la realización de las actividades respectivas (acceso directo) o tras una invitación vía email. En total se ha cumplimentado el cuestionario por 475 personas, 330 en acceso directo y 145 por email tras invitación.
• Un cuestionario dirigido a las personas que han realizado las actividades (investigador@s, técnic@s, voluntari@s, ...), cumplimentado igualmente de manera online. En concreto este cuestionario ha sido cumplimentado por 554 “investigadores”.
• Un cuestionario destinado a participantes menores de 18 años, con preguntas orientadas a captar su potencial vocación científica, y administrado también directamente tras la realización de la actividad y tras invitación por email. En total se han cumplimentado 196 cuestionarios a menores., [Modalidades de tratamiento de los datos] La grabación de los datos fue automática y la codificación de preguntas abiertas se realizó manualmente. En la depuración de los datos se han eliminado los casos que no habían cumplimentado el 75% del cuestionario., El libro de códigos está disponible en español y en traducción al inglés., [ES] La Noche Europea de los Investigadores es un evento de divulgación científica de alcance europeo que muestra de forma divertida e inspiradora la diversidad de la ciencia y su repercusión en la vida cotidiana de los ciudadanos.
El evento es una iniciativa de la Comisión Europea y se financia a través de las Acciones Marie Sklodowska Curie (MSCA) del Programa Marco de Investigación e Innovación de la UE.
La novena edición se celebró en 371 ciudades europeas, entre ellas las ocho capitales andaluzas el 27 de noviembre de 2020. Esta edición de La Noche en Andalucía ha sido mayoritariamente online, debido igualmente a la crisis sanitaria, de modo que se ha podido disfrutar directamente desde la web. Han sido más de 650 actividades para acercar la ciencia y a las personas que investigan al público en general, llevadas a cabo por casi 3.000 investigadores. Este informe presenta datos significativos para medir el impacto de la Noche Europea de los Investigadores en Andalucía, así como la evaluación realizada por sus participantes: asistentes e investigadores., [EN] The European Researchers' Night is a Europe-wide scientific dissemination event that displays the diversity of science and its impact on citizens' daily lives in fun, inspiring ways.

[Description of methods used for collection/generation of data] Individual capture histories were built from long-term individual capture-recapture monitoring of adult Scopoli’s shearwater Calonectris diomedea breeding in Pantaleu islet. Some of these individuals were also equipped with geolocators, that when recovered, may provide information of wintering movements and individual wintering areas. All the information about the deployment of geolocators devices and wintering areas visited are encoded in the individual capture histories. The file includes 23 annual encounter occasions, which translate into 45 coded encounter occasions, with the ‘inter’ encounter occasions encoding information about presence in the colony and migratory decisions, and the ‘intra’ occasions encoding information about whether a geolocator had been deployed or not at the end of the season., Long-term individual capture-recapture monitoring of adult Scopoli’s shearwater Calonectris diomedea breeding in Pantaleu islet has been carried out by: M Genovart, JM Igual, A Sanz-Aguilar, G Tavecchia, A Rotger & D Oro. Information from geolocators on wintering movement and wintering areas were analysed by R Ramos, T Militão, D Vicente-Sastre, B Garcia-Urdangarin & J González-Solís., Este fichero contiene información de las historias de captura individuales de Pardela cenicienta criando en el islote de Pantaleu, Mallorca, durante el período 2000-2022.

Solvents (chloroform and ethyl acetate) were obtained from Scharlau chemical company. The seawater (supplied by Rioka del Cantábrico, S.L.) was taken from the Matxitxako cape at the Urdaibai biosphere reserve in the Cantabrian Sea (Spain). The microalgae Chlorella Vulgaris was acquired to Biotiva (Germany) as a fine dehydrated powder and used without additional treatment. Almond hulls were from Marcona-type almonds harvested in Spain.-- A stainless-steel batch autoclave (300 mL) equipped with a speed-controlled mechanical stirrer (Parker Autoclave Engineers) was used for the hydrothermal experiments.-- Under a Creative Commons license BY-NC 4.0., The proximate analysis of algae and almond hulls were analyzed by thermogravimetric analysis (ISO-18134:2016, ISO-18122:2016 and ISO-18123:2016). The elemental composition of the feedstocks was determined using an elemental analyzer. The biochemical composition of almond hulls was determined by chemical titration according to Hu et al, whereas biochemical composition was provided by the supplier.-- Table S1: Properties and composition of seawater.

SUPPLEMENTARY MATERIAL FOR CONTROLLING CLAY SLIPS WITH A PROCESS VIBRATIONAL VISCOMETER [DATASET]
- Ansón-Casaos, Alejandro

- Maser, Wolfgang K.
- Benito, Ana M.

[Measurement details] In static measurements, the whole batch dispersion, having well-defined density and deflocculant ratio, was gently stirred with a spoon for approximately 1 min, and a fraction of it was transferred to a 50-mL vial. The measurement probe was inserted in the fluid, following instructions from the respective providers. In dynamic measurements, 3 batches of the clay dispersion (ρ = 1.55 g·cm-3, deflocculant ratio 0.44 wt.%) were added together into a 2 L rectangular hermetic container. Prior to measurements, the dispersion was gently mixed with a spoon. Both the viscometer probe and the stirring rotor, operating at 1,000 rpm, were simultaneously located at opposite sides of the container.
In the casting experiments, two different products were used: i) the Euroarce sanitary slip (ρ = 1.96 g·cm-3); and ii) an aqueous dilution of that sanitary slip, resulting in a density of ρ = 1.81 g·cm-3. The slip was hand stirred with a spoon and transferred into a plaster mould through a filling hole. The plaster mould, used to conform bar specimens measuring 12 x 3 x 1.5 cm3, consists of two symmetrical components joined together with adhesive tape. For measurement purposes, the VRV probe was introduced in the filled mould through the filling hole.-- Under a Creative Commons license BY-NC-ND 4.0., [Materials and equipment] Industrias Químicas del Ebro (Zaragoza, Spain) supplied the deflocculant solution of sodium silicate (3.3 SiO2·Na2O, 43% dry mass, NASIL 3.35).
Elemental analysis was acquired from Energy-dispersive X-ray spectroscopy (EDX) in a SEM-EDX Hitachi S-3400 N, equipped with a Si EDX analyser Röntec XFlash. Crystal structure was assessed by powder X-ray diffraction (XRD) in a Bruker AXS D8 Advance diffractometer. Electrolytic conductivity was measured using an Orion Star A112, with a 2-electrode probe, reference 011050MD, which had a nominal cell constant of 1.0 cm-1 and a measurement range from 1 μS·cm-1 to 20 mS·cm-1. The flow curve was determined in a Rotovisco Rheometer from Thermo Scientific.
The rotatory viscometer was a Brookfield DV-E (Brookfield Engineering, Middleboro, Massachusetts, USA), using LV3 and LV4 spindles, and operating at 30 rpm.-- [Preparation of clay dispersions] Dispersions were prepared from the raw clay at two concentrations, resulting in different final densities, and various ratios of deflocculant sodium silicate.-- [Chemical composition and mineralogical characterization] Both elemental analysis by EDX and the XRD pattern confirmed that the raw clay consisted of a mixture of alumiosilicate minerals.-- [Flow curve] The general flow characteristics of a control Euroarce clay dispersion, performed with a rotational rheometer, revealed the characteristic non-Newtonian shear-thinning behavior, where viscosity (η) strongly decreased with stirring shear rate (𝛾̇) (Figure S2) (Amorós et al., 2002; Amorós et al., 2010). The flow curve (η vs. 𝛾̇) was well fitted to the Sisko equation (Sisko, 1958):
𝜂=𝜂∞+𝐾𝛾̇𝑛−1
(Equation S1)
where η∞, K and n are parameters accounting for the viscosity of the Newtonian flow unit, the consistency factor and the power law index, respectively (Blissett and Rowson, 2013).-- [Electrolytic conductivity]
To evaluate the applicability of the VRV in monitoring clay viscosity, dispersions with well-defined densities (either 1.55 or 1.39 g·cm-3) and quantities of sodium silicate (< 0.7 wt.%) were examined.-- [Thixotropy assessment and the effect of density] A further assessment of thixotropy with the VRV is shown in Figure S5. Viscometer curves η vs. t were measured on four samples of a clay dispersion batch, each subjected to different initial rest periods. After the rest time, the dispersion was put in contact with the vibrational probe, and η value was monitored for a time of 30 min.-- Experimental; Chemical composition and mineralogical characterization; Flow curve; Electrolytic conductivity; Deflocculation curve; Thixotropy assessment and the effect of density., Peer reviewed
