Enhanced nitrogen removal of low carbon wastewater in denitrification bioreactors by utilizing industrial waste toward circular economy
2020
Aquaculture needs practical solutions for nutrient removal to achieve sustainable fish production. Passive denitrifying bioreactors may provide an ecological, low-cost and low-maintenance approach for wastewater nitrogen removal. However, innovative organic materials are needed to enhance nitrate removal from the low carbon effluents in intensive recirculating aquaculture systems (RAS). In this study, we tested three additional carbon sources, including biochar, dried Sphagnum sp. moss and industrial potato residues, to enhance the performance of woodchip bioreactors treating the low carbon RAS wastewater. We assessed nitrate (NO3−) removal and microbial community composition during a one-y…

Las agencias de calificación y la deuda pública en la Comunidad Valenciana
2020
Resumen El objetivo de esta investigación es analizar la influencia que han tenido los mayores niveles de endeudamiento público sobre los ratings emitidos por las agencias de calificación para la Comunidad Valenciana. La acumulación de déficits junto con el estallido de la burbuja inmobiliaria terminó por afectar de manera negativa a la contabilidad pública. Asimismo, los recursos transferidos a través del sistema de financiación tampoco ayudaron a revertir la insuficiencia de ingresos para la administración valenciana. Las restricciones presupuestarias fueron reflejadas de inmediato por las agencias de calificación a través de una reducción en sus ratings, generando dificultades para obten…
A Dataset of Annotated Omnidirectional Videos for Distancing Applications
2021
Omnidirectional (or 360°) cameras are acquisition devices that, in the next few years, could have a big impact on video surveillance applications, research, and industry, as they can record a spherical view of a whole environment from every perspective. This paper presents two new contributions to the research community: the CVIP360 dataset, an annotated dataset of 360° videos for distancing applications, and a new method to estimate the distances of objects in a scene from a single 360° image. The CVIP360 dataset includes 16 videos acquired outdoors and indoors, annotated by adding information about the pedestrians in the scene (bounding boxes) and the distances to the camera of some point…
The effect of grazing history on fungal diversity in broadleaved wood pastures
2012
Traditional rural biotopes such as wood pastures are species rich habitats which have been created by extensive agriculture. In all European countries both the quality and quantity of traditional rural biotopes have drastically decreased during the past century because of increasing farming intensity. This decline is causing a threat to many species, but very little is known about the conservation ecology of fungi living in wood pastures. Considering vascular plants, it is known that sites with long management history have higher species richness compared to abandoned sites. It is also known that species richness is highest with intermediate grazing intensity. In this study I investigated i…
A Noxious Weed Ambrosia artemisiifolia L. (Ragweed) as Sustainable Feedstock for Methane Production and Metals Immobilization
2023
Plants of the Ambrosia genus are invasive and cause many ecological problems, including the oppression of the growth of agricultural crops and native plants, land depletion, and the production of strong allergens. The use of weeds as a sustainable feedstock for biogas production, either methane or hydrogen, is a promising way to fulfill the energy needs of the current generation, eliminate the depletion of non-renewable carbon resources, and preserve the ecosystem degradation caused by invasive species impacts. A diversified microbial community was used as inoculum and Ambrosia artemisiifolia L. biomass as a substrate for anaerobic degradation and methane production. In this regard, the dev…
ANALYSIS OF HOWECOTOURISMIN PROTECTED AREAS INFLUENCE THE DEVELOPMENT OF LOCAL COMMUNITIES
2013
Tourism, which, by its specific, uses natural resources, is an important contribution to environmental damage. In this context, efforts to find and promote holiday forms that have a low environmentalimpact, forms known as ecotourism, ecological tourism, tourism in protected areas, green tourism. Tourism industry stakeholders have become increasingly sensitive to environmental issues and few are those who now believe commercial activities have nothing to do with the development of ecological actions. Also many tour operators believe that the natural resources have economic value only if they are reasonably valued.
Mentoring of Newly Qualified Teachers in the Educational Sense
2017
The importance of lifelong learning in teachers’ professional development has become increasingly topical issue globally. In teaching, especially the transition from education to occupation seems to be more challenging compared to other fields. It is evident that under the rapidly changing circumstances teachers’ professional knowledge has to be constantly renewed, and especially in the phase of transition from teacher education to working life, new approaches are needed. peerReviewed
La pedagogia di Aldo Capitini e la democrazia. Orizzonti di formazione per l'uomo nuovo
2014
L’educazione alla democrazia prospettata da Aldo Capitini viene riconsiderata alla luce delle nuove emergenze poste dall’attuale società del pluralismo; egli, con uno sguardo lungo e anticipatamente post-moderno, consegna alle nuove generazioni un’inedita idea di democrazia, l’omnicrazia, e rilancia il rapporto tra politica e religione come necessario per promuovere un’educazione che miri alla formazione integrale dell’uomo. La proposta del metodo nonviolento, la realizzazione di comunità educanti in cui ci si formi ad un agire politico consapevole e responsabile, la sinergia tra spiritualità e politica, l’approccio laico e insieme religioso, sono alcuni fra gli aspetti più attuali di una p…
Tourism-related informal interaction in Chembe, Malawi : an ethnographic study
2016
Tutkielmassa tarkastellaan turismin liittyvää vapaamuotoista kanssakäymistä paikallisten malawilaisten sekä ulkomaalaisten asukkaiden ja matkailijoiden välillä. Etnografinen pääaineisto on kerätty Malawissa keväällä 2013 ja se koostuu haastatteluista ja muistiinpanoista. Tosisijainen aineisto koostuu raporteista ja asiakirjoista, joiden tarkoitus on hahmotella ruohonjuuritason vuorovaikutukselle laajempi yhteiskunnallinen konteksti. Metodologisesti tutkielma hyödyntää ranskalaisen sosiologin ja etnologin Pierre Bourdieun esittelemää käytännön teoriaa ja sen keskeisiäkäsitteitä, jotka ovat kenttä, pääoma ja habitus. Tutkielman tarkoitus on valottaa niitä tekijöitä, jotka määrittävät eri toim…
