Carles Salvador i la infraestructura cultural valencianista
2015
This study analyzes how Salvador, as founder and collaborator, participated in various Valencian cultural institutions of his time: the Societat Castellonenca de Cultura, the Associació Protectora de l’Ensenyança Valenciana, the publications Taula de Lletres Valencianes and El Camí, Proa, Lo Rat-Penat, the Institut d'Estudis Valencians, and the Centre de Cultura Valenciana, among others.
Lauksaimnieks Elmārs Dubults - Jaunpils izaugsmes un vēstures veidotājs
2022
Novadpētniecība ir nozīmīgs ieguldījums kultūrvēsturiskā mantojuma izzināšanā un popularizēšanā. Katrai vietai, ko veidojuši cilvēki, ir sava vēsture un kultūra, un mums ir nepieciešamība izjust savu piederību tai. Pētījuma mērķis ir noskaidrot Elmāra Dubulta lomu un devumu Jaunpils attīstībā un kultūrvēsturiskā mantojuma saglabāšanā no 1968. gada līdz 90. gadu sākumam. Pētījums balstīts uz arhīvu, muzeju un ģimenes arhīva dokumentu liecībām, publikācijām presē un laikabiedru mutvārdu vēstures liecībām. Pētījuma rezultāti atklāj, ka Elmāram Dubultam, kā Jaunpils lopkopības izmēģinājuma stacijas vadītājam, ir bijusi nozīmīga loma Jaunpils kultūrvēsturiskā centra atjaunošanā un saglabāšanā, J…
Educación para la innovación agraria. Un modelo para la acción educativa
2019
[ES] Este estudio se centra en la figura del productor agrario valenciano y su comportamiento frente a la innovación. Adoptar una postura proclive a la innovación depende de múltiples factores que influyen en la gestión de la empresa agraria. Este estudio utiliza los datos procedentes de una encuesta a productores agrarios valencianos, diseñada ad hoc para la investigación, que profundiza en los factores socioeconómicos que pueden decantar al productor agrario hacia una postura favorable a la innovación. Posteriormente, el estudio se centra en obtener un perfil tipo que caracteriza al productor según sus características y las de su explotación, según su actitud innovadora y la orientación h…
Comparative assessment of a foam-based oxidative treatment of hydrocarbon-contaminated unsaturated and anisotropic soils.
2019
Abstract In situ delivery of liquid reagents in vadose zone is limited by soil anisotropy and gravity. The enhanced delivery of persulfate (PS) as oxidant, using a new foam-based method (F-PS) was compared at bench-scale to traditional water-based (W-PS) and surfactant solution-based (S-PS) deliveries. The goal was to distribute PS uniformly in coal tar-contaminated unsaturated and anisotropic soils, both in terms of permeability and contamination. Water was the less efficiently delivered fluid because of the hydrophobicity of the contaminated soils. Surfactant enhanced PS-distribution into contaminated zones by reducing interfacial tension and inverting soil wettability. Regardless of coal…
A new foam-based method for the (bio)degradation of hydrocarbons in contaminated vadose zone
2020
International audience; An innovative foam-based method for Fenton reagents (FR) and bacteria delivery was assessed for the in situ remediation of a petroleum hydrocarbon-contaminated unsaturated zone. The surfactant foam was first injected, then reagent solutions were delivered and propagated through the network of foam lamellae with a piston-like effect. Bench-scale experiments demonstrated the feasibility of the various treatments with hydrocarbon (HC) removal efficiencies as high as 96 %. Compared to the direct injection of FR solutions, the foam-based method led to larger radii of influence and more isotropic reagents delivery, whereas it did not show any detrimental effect regarding H…
Shear-thinning fluids for gravity and anisotropy mitigation during soil remediation in the vadose zone
2018
Abstract Surfactant foam has been proposed as an effective treatment fluid for in situ environmental remediation of soils. In the vadose zone, it could improve treatment homogeneity, but its use remains challenging. To better understand and predict foam formation and propagation in vadose zone, we studied them in 24 soils with wide range of properties (including permeability: 2 10−12 to 3.3 10−9 m2). Foam rheology showed to be complex and mostly influenced by soil permeability and grading. Below 2 10−11 m2, foam propagation velocity was not influenced by permeability. Conversely, slight shear thinning to Newtonian behavior was observed for higher permeabilities. Benefits for remediation in …
Variation in the stable isotope trophic position of the bluefish Pomatomus saltatrix (Linnaeus, 1766) from two Mediterranean sites: insights from a g…
2022
A direct consequence of sea warming is the shift in the distribution range of thermo-tolerant species that have the potential to determine novel inter-specific interactions, ultimately altering food web structures and ecosystem processes. In this study, we investigated the trophic position of the bluefish Pomatomus saltatrix (Linnaeus, 1766), a pelagic predator that has recently expanded its distribution in the Mediterranean basin and for which scant information is available on its functional role in recently-colonised areas. Nitrogen and carbon stable isotopes were determined in muscle tissues of bluefish specimens collected in south-east Italy in the Gulf of Taranto (NW Ionian Sea) and in…
