Towards a reduction of greenhouse gas emission from wastewater treatment plants: a new plant wide experimental and modelling approach
2016
The increasing interest in greenhouse gas (GHG) emissions from wastewater treatment plants (WWTPs) has led to the development of new tools for their design and management. Studies about gas emissions show that the sewer collection and the wastewater treatment plant are anthropogenic GHG potential sources, so they contribute to the climate change and air pollution. A wastewater treatment plant receives wastewater from sewers and, while produces treated water for discharge into surface water, emits the three major greenhouse gases, CO2, CH4, and N2O, during the treatment processes, and additional amounts of CO2 and CH4 from the energy demands (Bani Shahabadi et al., 2009). Indeed, energy cons…
Longitudinal analysis of Spanish doctoral theses in education (1841-2012)
2014
This article analyzes the research output of doctoral theses in the field of Education defended in Spain from 1841-2012. It offers a quantified global and diachronic view of such series. As a landmark to note is the fact that until 1954, obtaining a doctoral degree was centralized at the Complutense University of Madrid. They are used as search engines bibliographic databases: TESEO and institutional repositories, and basic bibliography of the area to carry out the collection of the sample. The contrasting hypothesis is to verify whether the time series partially follows the pattern of growth of the science of Derek J. de Solla Price. The central finding is that the Spanish production of do…
Interactions, spillovers de connaissance et croissance des économies modernes. Faut-il préférer la globalisation ou la proximité géographique ?
2009
Globalisation and metropolisation in modern economies induce some locational strategies of knowledge based activities towards cities and deeply increase trade and move of ideas across cities. In that context, we study the way knowledge spillovers have influenced the economic growth of 82 European Metropolises over the 1990-2005 period. We model knowledge spillovers across cities according to three specific interaction patterns depending either on geography or on global advanced services or thought a combination of these patterns. We show that the mixed pattern matters the best for economic growth of cities in Europe.
Ustekinumab therapy changes the transcriptional activity pattern of TGF-β1–3 genes
2019
Introduction One of the examples of genes whose expression can be altered by the action of ustekinumab is TGF-β. It is a pleiotropic cytokine whose activity affects psoriatic changes and the state of homeostasis of the whole organism. Aim To evaluate the effect of ustekinumab on the transcriptional activity of TGF-b family genes in patients with psoriatic arthritis and to check whether the results obtained can be helpful in monitoring the progress of treatment. Material and methods From total PBMCs obtained from peripheral blood of 14 patients with psoriatic arthritis, total RNA was isolated. The expression level of the TGF-β1, TGF-β2 and TGF-β3 genes was determined by RT-qPCR in real time.…
Approccio alla caratterizzazione di un lembo di bosco vetusto: il caso di Monte Egitto
2017
An integrated approach to characterize an old growth forest patch; the Monte Egitto case study Old growth forests, i.e. forests which have achieved a remarkable age without or with a very limited disturbance, are nowadays subject of detailed studies in order to understand their characters and capacity of ecosystems services providing. In Sicily only few wooded areas are classified as old growth forest, following the heavy land use change toward agriculture during the centuries. This paper reports the results of a study carried out to characterize the vegetation of a little crater on the Mount Etna, where a residual open wood of Quercus congesta (an endemic oak of Southern Italy) survived th…

Wpływ czynników biotycznych i abiotycznych na wzrost i rozwój Dionaea muscipula oraz warunki prowadzenia hodowli
2018
W pracy przedstawiono sposób namnażania rośliny owadożernej z rodziny Droseraceae –Dionaea muscipula (Muchołówka amerykańska), występującej w środowisku naturalnym jedynie na terenach Karoliny Północnej oraz Karoliny Południowej oraz sposoby jej uprawy wpływające na jakość hodowli. Podstawowymi czynnikami są prawidłowe nasłonecznienie, nawodnienie, zapewnienie roślinie odpowiedniego podłoża, systematyczna pielęgnacja i prawidłowa temperatura otoczenia. Rośliny te nie wymagają nawożenia m.in. ze względu na umiejętność pozyskiwania składników ze schwytanych owadów. Pomimo faktu, że Dionaea muscipula jest gatunkiem monotypowym, powstało wiele różnorodnych kultywarów występujących w hodowlach n…
A Contribution to the Schumpeterian Growth Theory and Empirics
2010
Soumis à Journal of Economic Growth; Document de Recherche LEO 2008-25; Cet article propose un cadre théorique et méthodologique unifie caractérisé par la priseen compte explicite des intéractions technologiques dans la modélisation des processus decroissance en adoptant une perspective Schumpétérienne. L'interdépendance globale impliquée par les spillovers internationaux de R&D doit être intégrée non seulement dans lamodélisation théorique mais également dans la spécification économétrique qui en découle.L'économétrie spatiale apparaît alors naturellement comme la méthodologie adéquate pourtraiter le problème de l'estimation de telles spécifications. Le modèle économétrique que nousproposo…
International R&D spillovers in the multi-country Schumpeterian growth model
2007
en ligne : http://ungaro.u-bourgogne.fr/pages/Documents%20de%20travail/Economie/e2007-04.pdf; Document de travail du LEG 2007-04; This paper reconsiders the multi-country Schumpeterian growth model and its empirical implications. We first show that the model implies a spatial econometric reduced form. Indeed, the global interdependence implied by international R&D spillovers needs to betaken into account in the theoretical model as well as in the empirical model. The spatial econometric model we propose includes the neoclassical growth model as a particular case. We can therefore test explicitly the role of R&D investment in the long run growth processagainst the Solow growth model which is…
