Reconstruction of humins formation mechanism from decomposition products: A GC-MS study based on catalytic continuous flow depolymerizations
(Elsevier, 2019)Humins, a by-product of biomass chemical conversion technologies, still present controversies in their structural and mechanistic identification. Traditional studies of the structure and mechanism have focused so far on ... -
Review. The evolution of research regarding the economics of irrigation water
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, 2010)This work analyses the main research trends (subjects, methodology used, countries of the authors and data) in the economics of irrigation water during the last 10 years (2000-2009). For this purpose, a quantitative ... -
Scrap waste automotive converters as efficient catalysts for the continuous-flow hydrogenations of biomass derived chemicals
(RSC, 2020)The catalytic activity of the scrap ceramic-core of automotive catalytic converters (SCATs) was investigated in the continuous-flow hydrogenation of different biomass derived chemicals. The waste SCATs powders were deeply ... -
Seasonal Climate Forecast Skill Assessment for the Management of Water Resources in a Run of River Hydropower System in the Poqueira River (Southern Spain)
(MDPI, 2020)Run of river (RoR) hydropower systems, despite being one of the most cost-effective and environmentally benign energy technologies, have the disadvantage that production is not constant because it is subject to a high ... -
Sequential Exposure to Obesogenic Factors in Females Rats: From Physiological Changes to Lipid Metabolism in Liver and Mesenteric Adipose Tissue
(Nature Research, 2017)During their lifetime, females are subjected to different nutritional and hormonal factors that could increase the risk of obesity and associated comorbidities. From early postnatal periods until the postmenopausal phase, ... -
Social capital formation in Mexican ejidos. Land decisions after the article 27 constitutional reform
(Instituto de Estudios Sociales Avanzados (CSIC), 2014)The Mexican ejidos are complex land-based structures developed by the post-revolutionary state formation (1915-1992). The success of some ejidos was based on trust ties. With the economic liberalization of the country ... -
Social Network Analysis of the Stakeholders Involved in the Dromedary Sector in the Mediterranean Region
(MDPI, 2021)Marginal arid zones in the south Mediterranean are faced with the dramatic departure of their labor forces through migration. Interest in the capacity of the dromedary species to enhance desert ecosystems and to be a ... -
Soil Productivity Degradation in a Long-Term Eroded Olive Orchard under Semiarid Mediterranean Conditions
(MDPI, 2021)Olive groves are one of the most important agro-systems in the Mediterranean basin, and the Andalusia region produces the highest quantity of olive oil in Europe. The aim of this work was to evaluate the long-term (15 ... -
Some problems of the determination of best management practices to maintain the quality of agricultural soils
