Long-term non-isothermal reactive transport model of compacted bentonite, concrete and corrosion products in a HLW repository in clay
(Elsevier, 2017)[Abstract:] Radioactive waste disposal in deep geological repositories envisages engineered barriers such as carbon-steel canisters, compacted bentonite and concrete liners. The stability and performance of the bentonite ... -
Macro-Scale Spatial Modeling Reveals the Role of Soil Organic Matter Quality in CO2 Emissions
(Elsevier, 2023-08-04)[Abstract] Carbon dioxide (CO2) emissions from agricultural soils result from the interaction of various factors that regulate the quantity and quality of organic material. Our objective was to assess changes in soil CO2 ... -
Modeling cesium migration through Opalinus clay: a benchmark for single- and multi-species sorption-diffusion models
(Springer, 2021)[Abstract:] Sophisticated modeling of the migration of sorbing radionuclides in compacted claystones is needed for supporting the safety analysis of deep geological repositories for radioactive waste, which requires robust ... -
Modelling of the long-term evolution and performance of engineered barrier system
(EDP Sciences, 2022)[Abstract:] Components of the so-called “multiple-barrier system” from the waste form to the biosphere include a combination of waste containers, engineered barriers, and natural barriers. The Engineered Barrier System ... -
New Insights Into the Production, Characterization and Potential Uses of Vineyard Pruning Waste Biochars
(Elsevier, 2023-10-04)[Abstract] Vineyard pruning waste (VP) can be converted into a useful char using pyrolysis as part of a valorization strategy. This study analyzed the effect of temperature (300 and 600 °C) and residence time (1 and 3 h) ... -
Normalized sensitivities and parameter identifiability of in situ diffusion experiments on Callovo–Oxfordian clay at Bure site
(Elsevier, 2008)Diffusion of inert and reactive tracers (DIR) is an experimental program performed by ANDRA at Bure underground research laboratory in Meuse/Haute Marne (France) to characterize diffusion and retention of radionuclides in ... -
Obtención de un Modelo Dinámico para un Robot 3RRR Basado en Teoría de Screws
(Comité Español de Autonomática (CEA-IFAC), 2018)[Resumen] En este artículo se propone una nueva técnica para la obtención de un modelo dinámico de robots 3RRR a partir de un modelo cinemático basado en teoría de screws, la cual permite obtener la cinemática de un robot ... -
Past Sewage Sludge Application Did Not Alter Soil Chemical Properties or Abundance of Most Abundant Bacterial Families in an Agroforestry System
(Elsevier, 2023-02-10)[Abstract] Forest management practices impact the amount of organic matter reaching the soil, but also the soil properties and/or vegetation composition that influence soil microbiome structure and composition. After ... -
Path coefficient analysis, a different approach to identify soil quality indicators
(Universidade Federal de Campina Grande, 2019-06-04)[Abstract] Soil quality indicators related to water erosion reduction can assist with correct soil management. The objective of this research was to identify some variables that could be used as soil quality indicators ... -
Pedotransfer function to estimate the soil structural “S” index and spatial variability in an oxisol within a livestock farming system
(Associação Brasileira de Engenharia Agrícola, 2020-02-17)[Abstract]: Various attributes are often required to build soil quality indicators. However, determining these attributes is time-consuming and requires several specific devices. Thus, it is desirable to develop indexes ... -
Phosphorus Fractionations and Availability in Areas under Different Management Systems in the Cerrado
(MDPI, 2023-03-24)[Abstract] The input of organic matter in the soil by the no-tillage system (NTS) increases as the system becomes established, raising the levels of organic phosphorus (P) and reducing the P soil adsorption. This study ... -
Post-fire Management Effects on Hillslope-Stream Sediment Connectivity in a Mediterranean Forest Ecosystem
(Elsevier, 2022)[Abstract] Forest fires intensify sediment transport and aggravate local and off-site consequences of soil erosion. This study evaluates the influence of post-fire measures on structural and functional sediment connectivity ... -
Post-fire Management Effects on Sediment (Dis)Connectivity in Mediterranean Forest Ecosystems: Channel and Catchment Response
(John Wiley & Sons, 2021)[Abstract] Forest fires and post-fire practices influence sediment connectivity (SC). In this study, we use the ‘aggregated index of connectivity’ (AIC) to assess SC in five Mediterranean catchments (198–1090 ha) affected ... -
Post-fire Practices Benefits on Vegetation Recovery and Soil Conservation in a Mediterranean Area
(Elsevier, 2021)[Abstract] Post-fire practices (PFP) aim to reduce soil erosion and favour vegetation recovery, but their effectiveness is spatially heterogeneous and under debate because of the economic and environmental costs. This study ... -
Predicting Weathering Indices in Soils Using FTIR Spectra and Random Forest Models
(Elsevier, 2021-05-19)[Abstract] Weathering indices based on the relative proportions of different chemical elements are a useful tool to investigate the degree of weathering of soils. This characterization is missing in West Azerbaijan, northern ... -
Reactive transport model of gypsum karstification in physically and chemically heterogeneous fractured media
(MDPI, 2022)[Abstract:] Gypsum dissolution leads to the development of karstic features within much shorter timescales than in other sedimentary rocks, potentially leading to rapid deterioration of groundwater quality and increasing ... -
