Analysis of isotopes of plutonium in water samples with a PSresin based on aliquat⋅336
There is a necessity to have techniques capable to perform rapid determinations of specific radionuclides with the aim to provide fast response in emergency situations where a large number of samples need to be measured ...
Simultaneous determination of iron and copper using screen-printed carbon electrodes by adsorptive stripping voltammetry with o-phenanthroline.
The simultaneous voltammetric determination of iron and copper was accomplished by an unmodified screen-printed carbon electrode based on the complexation with o-phenanthroline assisted by the reducing agent ferrocyanide. ...
Analysing the contribution of intermittent rivers to beta diversity can improve freshwater conservation in Mediterranean rivers
In Mediterranean climate regions, intermittent rivers (IRs) harbor highly dynamic communities with species and trait composition changing over time and space. Simultaneously considering multiple biodiversity facets and a ...
Novel insights on new particle formation derived from a pan- european observing system
The formation of new atmospheric particles involves an initial step forming stable clusters less than a nanometre in size (<~1 nm), followed by growth into quasi-stable aerosol particles a few nanometres (~1-10 nm) and ...
Livestock aggregated samples for monitoring viruses infecting animals and potentially zoonotic viral pathogens
Active surveillance of livestock pathogens is essential to prevent animal health losses and zoonotic spillover. This study evaluted aggregated environmental sampling as a non-invasive approach for monitoring swine- and ...
An interdisciplinary research agenda to explore the unintended consequences of structural flood protection
One common approach to cope with floods is the implementation of structural flood protection measures, such as levees or flood-control reservoirs, which substantially reduce the probability of flooding at the time of ...
High-resolution (sub-decadal) pollen analysis of varved sediments from lake Montcortès (South-central pre-Pyrenees): a fine-tuned record of landscape dynamics and human impact during the last 500 years.
A high-resolution (average 6 years/sampling interval) palaeoenvironmental reconstruction using pollen, charcoal and non-pollen palynomorphs was carried out on annually laminated sediments of Lake Montcortès (southern ...
Human management and landscape changes at Palaikastro (Eastern Crete) from the Late Neolithic to the Early Minoan period
The intense cultivation of olives, together with the diversification and specification of crops has been hypothesized as a cornerstone in the socio-economic transformations occurred during the Early bronze age in Crete, ...
Effective dispersal and density-dependence in mesophotic macroalgal forests: Insights from the Mediterranean species Cystoseira zosteroides
Dispersal and recruitment are fundamental processes for population recovery following disturbances in sessile species. While both processes are well understood for many terrestrial species, they still remain poorly resolved ...
La Apuesta por el patrimonio histórico-artístico en el turismo de montaña. El caso del Pirineo Catalán.
[spa] La escasa presión humana sobre los espacios de alta montaña, de características físicas extremas, ha permitido mantener y conservar un patrimonio natural y cultural de innegable valor y atractivo que, con el paso del ...
Arsenosugar extracted from algae: Isolation by anionic exchange solid-phase extraction
Obtaining reliable speciation data for evaluating dietary exposure, and increasing understanding of arsenic biochemistry in algae, are hindered by the availability of suitable standards of arsenosugars, the major species ...
Grazing activities in the southern central Pyrenees during the last millenium as deduced from the non-pollen palynomorphs (NPP) record of lake Montcortès
Human activities during the last millennium have shaped most of the present-day landscapes. During this time, in the southern central Pyrenees several climate periods and phases of variable human disturbance have driven ...
Evaluation of uncertainties in mean and extreme precipitation under climate change for northwestern Mediterranean watersheds from high-resolution Med and Euro-CORDEX ensembles
The climate change impact on mean and extreme precipitation events in the northern Mediterranean region is assessed using high-resolution EuroCORDEX and Med-CORDEX simulations. The focus is made on three regions, Lez and ...
Chloride-attachment atmospheric pressure photoionisation for the determination of short-chain chlorinated paraffins by gas chromatography-high-resolution mass spectrometry
In this work, a new gas chromatography-high-resolution mass spectrometry (GC-HRMS) method based on atmospheric pressure photoionisation (APPI) has been developed for the accurate determination of short-chain chlorinated ...
El interés geográfico de los documentos históricos en la explicación científica del foco glaciar del Corral del Veleta (Sierra Nevada, España) durante la Pequeña Edad del Hielo
La documentación histórica analizada ha ratificado su utilidad en el estudio del origen y evolución del foco glaciar del Corral del Veleta, instalado en el macizo de Sierra Nevada (España). La información obtenida, que ...
Characterization and classification of Spanish paprika (Capsicum annuum L.) by liquid chromatography coupled to electrochemical detection with screen-printed carbon-based nanomaterials electrodes
Screen-printed electrodes based on graphite, carbon nanotubes, carbon nanofibers, and graphene were tested as amperometric detectors for the determination of polyphenols by high performance liquid chromatography (HPLC). ...
Constraints on political autonomy in decentralized Spain? Analysing the impact of territorial financing and governments' ideology on regional policy-making
This article analyses the impact of state decentralization on one aspect of territorial diversity, specifically on the policy discretion of regions, as an expression of their political autonomy for self-government. Our ...
Effects of Didymosphenia geminata massive growth on stream communities: Smaller organisms and simplified food web structure
This study aims to contribute to the understanding of the impact of Didymosphenia geminata massive growths upon river ecosystem communities' composition and functioning. This is the first study to jointly consider the ...
The unexplored virome of two Atlantic coast fish: contribution of next-generation sequencing to fish virology
Much of the knowledge on viruses is focused on those that can be propagated using cell-cultures or that can cause disease in humans or in economically important animals and plants. However, this only reflects a small portion ...
The sixteenth century panel Virgin with the Child and an Angel, confluences of material characterization and iconography
Attribution of the panel The Virgin with the Child and an Angel today in the Art Museum of Girona is under study due to the existence of two hypotheses, both of them not thoroughly documented, pointing Jan Massys and ...
