Olefina arinen ekoizpena hondakin plastikoetatik
Lan honetan, poliolefinetatik abiatuta, olefinak ekoizteko bi estrategia ezberdin alderatzen dira. Bi kasuetan, lehen etapan, iturri-ohantze konikoko erreaktorean plastikoaren pirolisia egin da. Bigarren etapari dagokionez, bi aukera daude pirolisian sorturiko hegazkorren crackinga egiteko; alde batetik, ohantze finkoan, cracking katalitikoa HZSM-5 zeolita katalizatzaile modura erabiltzea, eta, bestetik, tutu anitzeko erreaktorean tenperatura altuko cracking termikoa erabiltzea; In this paper two strategies focused on the production of light olefins from polyolefins are compared. In both cases, the first stage consists in the plastics pyrolysis in a conical spouted bed reactor. With respect to the second stage, two different alternatives have been studied to perform the in-line cracking of the volatiles formed in pyrolysis.In the first alternative, a HZSM-5 catalyst is placed in a fixed bed reactor to perform the catalytic cracking, while in the second one a multitubular reactor is used for the high temperature thermal crackin
QTLeap - Traducción de calidad mediante tratamientos profundos de ingeniería lingüística
The goal of this FP7 European project is to contribute for the advancement of quality machine translation by pursuing an approach that further relies on semantics, deep parsing and linked open data.El objetivo de este proyecto europeo FP7 es contribuir a la mejora en la calidad de la traducción automática mediante el uso de semántica, análisis sintáctico profundo y el uso de datos abiertos entrelazados.The research leading to these results was carried out as part of the QtLeap project funded by European Community (FP7-ICT-2013.4.1-610516)
Assessing Knowledge Gaps and Management Needs to Cope With Barriers for Environmental, Economic, and Social Sustainability of Marine Recreational Fisheries: The Case of Spain
Este artículo contiene 14 páginas, 4 figuras.The European Parliament is concerned about the lack of information on the relevance
of nine million Europeans engaged in marine recreational fishing (MRF), committing
Member States to encourage environmental and socioeconomic sustainability of the
sector. The objective of this paper is to provide recommendations to guide research
actions and management policies, based on the case of Spain, a key country because
its complex administrative regimen and the intensive use of its coasts, including
900,000 recreational fishers. A review of the state of the knowledge was performed to
identify research gaps, while governance challenges were identified in an International
Symposium on MRF. In the last two decades research on MRF was remarkable
(139 publications). However, public investment in research (€2.44 million in the same
period) should be improved to cover knowledge gaps on socioeconomic relevance,
on impacts on vulnerable species and on implications of global warming. The license
system should be standardized to allow estimation of effort, catch and expenditure.
Social networks, mobile applications, fisher ecological knowledge, and citizen science
programs could help to develop cost-effective research and management. Sciencebased,
adaptive policies should improve the allocation of resources between MRF and
other stakeholders, introducing co-management to reduce conflicts.This work received funds from the Xunta de Galicia under

Application of ecological risk assessment based on a novel TRIAD-tiered approach to contaminated soil surrounding a closed non-sealed landfill
The Ecological Risk Assessment (ERA) is a reliable tool for communicating risk to decision makers in a comprehensive and scientific evidence-based way. In this work, a site-specific ERA methodology based on the TRIAD approach was applied to contaminated soil surrounding a closed non-sealed landfill, as a case study to implement and validate such ERA methodology in the Basque Country (northern Spain). Initially, the procedure consisted of the application of a Parameter Selection Module aimed at selecting the most suitable parameters for the specific characteristics of the landfill contaminated soil, taking into consideration the envisioned land use, intended ecosystem services and nature of contaminants. Afterwards, the selected parameters were determined in soil samples collected from two sampling points located downstream of the abovementioned landfill. The results from these tests were normalized to make them comparable and integrable in a risk index. Then, risk assessment criteria were developed and applied to the two landfill contaminated soil samples. Although the lack of a proper control soil was evidenced, a natural land use was approved by the ERA (at Tier 2) for the two landfill contaminated soils. However, the existence of a potential future risk resulting from a hypothetical soil acidification must be considered.This work was financially supported by the BERRILUR3-Etortek (Basque Government) (IE09-242) and MINECO AGL2012-39715-CO3-01/02 projects
First Assessment of the Impacts of the COVID-19 Pandemic on Global Marine Recreational Fisheries
This work is the result of an international research effort to determine the main impacts of the COVID-19 pandemic on marine recreational fishing. Changes were assessed on (1) access to fishing, derived from lockdowns and other mobility restrictions; (2) ecosystems, because of alterations in fishing intensity and human presence; (3) the blue economy, derived from alterations in the investments and expenses of the fishers; and (4) society, in relation to variations in fishers? health and well-being. For this, a consultation with experts from 16 countries was carried out, as well as an international online survey aimed at recreational fishers, that included specific questions designed to capture fishers? heterogeneity in relation to behavior, skills and know-how, and vital involvement. Fishers? participation in the online survey (5,998 recreational fishers in 15 countries) was promoted through a marketing campaign. The sensitivity of the fishers? clustering procedure, based on the captured heterogeneity, was evaluated by SIMPER analysis and by generalized linear models. Results from the expert consultation highlighted a worldwide reduction in marine recreational fishing activity. Lower human-driven pressures are expected to generate some benefits for marine ecosystems. However, experts also identified high negative impacts on the blue economy, as well as on fisher health and well-being because of the loss of recreational fishing opportunities. Most (98%) of the fishers who participated in the online survey were identified as advanced, showing a much higher degree of commitment to recreational fishing than basic fishers (2%). Advanced fishers were, in general, more pessimistic about the impacts of COVID-19, reporting higher reductions in physical activity and fish consumption, as well as poorer quality of night rest, foul mood, and raised more concerns about their health status. Controlled and safe access to marine recreational fisheries during pandemics would provide benefits to the health and well-being of people and reduce negative socioeconomic impacts, especially for vulnerable social groups.Fil: Pita, Pablo.
