Quantification of kinetic parameters for heterotrophic bacteria via respirometry in a hybrid reactor
2010
Over the last decade new technologies are emerging even more for wastewater treatment. Among the new technologies, a recent possible solution regards Moving Bed Biofilm Reactors (MBBRs) that represent an effective alternative to conventional processes. More specifically such systems consist in the introduction of plastic elements inside the aerobic reactor as carrier material for the growth of attached biomass. Recently, one of the mostly used alternatives is to couple the Moving Bed Biofilm Reactor (MBBR) process with the conventional activated sludge process, and the resulting process is usually called HMBBR (Hybrid MBBR). In the MBBR process the biofilm grows attached on small plastic el…
Nitrous oxide from moving bed based integrated fixed film activated sludge membrane bioreactors
2017
Abstract The present paper reports the results of a nitrous oxide (N 2 O) production investigation in a moving bed based integrated fixed film activated sludge (IFAS) membrane bioreactor (MBR) pilot plant designed in accordance with the University of Cape Town layout for biological phosphorous removal. Gaseous and liquid samples were collected in order to measure the gaseous as well as the dissolved concentration of N 2 O. Furthermore, the gas flow rate from each reactor was measured and the gas flux was estimated. The results confirmed that the anoxic reactor represents the main source of nitrous oxide production. A significant production of N 2 O was, however, also found in the anaerobic …
Drones - New technologies for geophysics?
2015
Drones, also referred as Unmanned Aircraft Systems (UAS), Unmanned Aerial Vehicles (UAV) or Remotely Piloted Aircraft (RPA), are aircraft without pilot on board. USA is today the leading country in the field of UAS but recently, seven European countries have pledged to launch joint programs for drones, with the aim of producing the next generation of UAS before 2020. According to some studies on the potential market of UAS in Europe, the geoscience sector is definitely one of the most promising. In this paper, we bring a short description and classification of drones, according to their sized and shaped, with particular attention to the advantages and drawbacks of each type in reference to …
David against Goliath: Diagnosis and Strategies for a Niche Sport to Develop a Sustainable Fan Community
2021
Pilota, played using the hands, is a niche sport with origins dating back to Greco-Roman times. In the Valencian region of Spain, an indigenous version of the sport is played with healthy participation rates despite having to compete with the major global sports. This study is aimed at understanding the current situation of this sport in terms of knowledge, transmission channels, fan experience and media consumption, as well as the brand strategy challenges it faces for building a stable and sustainable fan community. The methodology consists of a combination of quantitative and qualitative techniques. Nearly 1500questionnaires completed across three study universes, four focus groups and 3…
Marihuānas dekriminalizācija Eiropas Savienībā kā sociālā kustība 21. gadsimtā
2016
Maģistra darbs „Marihuānas dekriminalizācija Eiropas Savienībā kā sociālā kustība 21.gadsimtā” ir veltīts Eiropas iedzīvotāju uzskatu un tendenču attīstības novērošanai. Juridiskais statuss marihuānas personiskai lietošanai ir viens no pretrunīgākajiem politiskajiem jautājumiem, kas iezīmē demokrātijas kontekstā pastāvošo konfliktu starp veselības aizsardzības un vienlīdzības principiem. Darbā ir izpētīts, kā attīstījusies marihuānas politika ASV, Nīderlandē un Latvijā, un kas sekmēja stingrākas marihuānas politikas veidošanu Eiropas Savienībā. Pētniecības metode ir gadījuma analīze, kuras rezultātā tiek izprasta Eiropas Pilsoņu Iniciatīvas tendence sociālās kustības perspektīvā.
ASSESSMENT OF LATVIAN PENSION SYSTEM IN THE CONTEXT OF EUROPEAN PILLAR OF SOCIAL RIGHTS
2021
Latvian pension system is considered to be one of the most sustainable, but it should be mentioned that financial sustainability may be achieved in different ways and sometimes the aspects of sustainability are estimated without considering system’s ability to provide equity, equality and adequacy of retirement provision. The European Pillar of Social Rights has been proclaimed in 2017. According to this statement delivering on the principles and rights defined under the Pillar is the joint responsibility of the EU institutions, member states, social partners and other stakeholders. The 3rd chapter devoted to social protection and inclusion establishes the key approaches to determining the …

Latvijas Republikas nozīmes pilsētu fiskālā stāvokļa novērtējums 2008.-2017. gadā
2019
Nereti iemesls valsts ekonomiskajai krīzei ir pašvaldību finansiālās problēmas. Tomēr lielākajā daļā Eiropas valstu, arī Latvijā, pašvaldību fiskālā stāvokļa novērtēšana netiek tik strikti veikta un regulēta kā tas notiek nacionālā līmenī. Darba mērķis ir noskaidrot, kāds ir deviņu Latvijas republikas nozīmes pilsētu fiskālais stāvoklis no 2008. līdz 2017. gadam, izmantojot fiskālā stāvokļa testus. Tiek veikta arī fiskālā stāvokļa prognozēšana, ņemot vērā sociālekonomisko, tostarp, demogrāfisko, faktoru tendences. Pētījuma rezultāti norāda, ka republikas nozīmes pilsētu fiskālais stāvoklis ir atšķirīgs – sastopama gan fiskālā veselība, gan fiskālais stress.
Morphological and genetic diversity within Pilosella hoppeana aggr. (Asteraceae) in Italy and taxonomic implications
2013
Morphological variation, ploidy level and genetic diversity have been studied on 10 populations of the Pilosella hoppeana aggr. from the Alps, Abruzzo, Calabria and Sicily.Chromosome counts showed that the plants from Abruzzo and those from Sicily are tetraploid (2n = 36); they are assigned to P. hoppeana subsp. macrantha. The plants from the Alps (P. hoppeana subsp. hoppeana) and those from Calabria are diploid. The Calabrian populations, previously included in P. hoppeana subsp. macrantha, are shown to belong to a separate species, P. leucopsilon. The principal component analysis, based on 25 morphological characters, allowed distinguishing clearly four groups. An allozymes study using 10…
Food and religion in sicily—a new green tourist destination by an ancient route from the past
2021
The Francigena Way (Via Francigena) is a long international itinerary that was awarded recognition as a Culture Route of the Council of Europe. It starts in Canterbury (UK), touches 13 European regions and ends in Rome. An ancient track of this route is in Sicily (Southern Italy), and its name is Magna Via Francigena (Great Francigena Way). This track is a pilgrimage route that connects two ancient port cities, Palermo and Agrigento, passing through internal rural territories that now deal with the exodus of population from rural to urban areas. The route passes through the Sicilian territory named “Upper-Belìce corleonese”, a rural area around the city of Corleone (a little village known w…
