Philology within the framework of Semiotic Textology. János S. Petőfi’s scientific legacy II

2019

This paper is addressed to linguists and, ideally, to philologists and literary critics. János S. Petőfi formulated his Semiotic Textology within a context of Macro-Disciplines (MD) and within an interdisciplinary context (ID). Petőfi did not give much information about the relationship between Semiotic Textology and other disciplines, such as Philology and Literary Criticism. Textual Linguistics is chronologically the first among the disciplines participating in Natural Text Processing as sub-procedure of Natural Language Processing. On the other hand, Literary Criticism is the last discipline of the procedure, because it expresses artistic evaluation. The connections between the disciplin…

Biomethane Production from Anaerobic Co-Digestion of Selected Organic Fraction of Municipal Solid Waste (OFMSW) with Sewage Sludge: Effect of the Ino…

2021

The aim of this study was to evaluate the effect of the inoculum to substrate ratio (ISR) and the mixture ratio between organic fraction of municipal solid waste (OFMSW) and sewage sludge (SS) on the methane production potential achievable from anaerobic co-digestion (AcoD). Biochemical Methane Potential (BMP) assays at mesophilic temperature were used to determine the best AcoD configuration for maximizing methane yield and production rate, as well as to address possible synergistic effects. The maximum methane yield was observed at ISR of 1 and 60% OFMSW: 40% SS as co-digestion mixture, whereas the highest methane production rate was achieved at ISR of 2 with the same mixture ratio (207 m…

Assessment of organic waste management methods through energy balance

2014

In Italy, the Organic Fraction of Municipal Solid W aste (OFMSW) is nowadays landfilled or processed through aerobic composting. The Italian towns curre ntly support a high cost for OFMSW disposal and cause a high environmental impact, because of long distance s travelled from towns to a few available landfills and fewer treatment places, as well as the used waste m anagement methods. An interesting option for OFMSW is Anaerobic Digestion (AD), producing biogas and “digestate”. In this survey a theoretical biogas plant was placed near a town of Sicily Region (Italy), centra lised with reference to the area considered for pro ducing OFMSW. The distances travelled every year to transport OFMS…

Economic and environmental sustainability of an AnMBR treating urban wastewater and organic fraction of municipal solid waste

2016

[EN] The objective of this study was to evaluate the economic and environmental sustainability of a sub- merged anaerobic membrane bioreactor (AnMBR) treating urban wastewater (UWW) and organic fraction of municipal solid waste (OFMSW) at ambient temperature in mild/hot climates. To this aim, power requirements, energy recovery from methane (biogas methane and methane dissolved in the effluent), consumption of reagents for membrane cleaning, and sludge handling (polyelectrolyte and energy consumption) and disposal (farmland, landfilling and incineration) were evaluated within different operating scenarios. Results showed that, for the operating conditions considered in this study, AnMBR tec…

Quantum walks as simulators of neutrino oscillations in a vacuum and matter

2016

We analyze the simulation of Dirac neutrino oscillations using quantum walks, both in vacuum and in matter. We show that this simulation, in the continuum limit, reproduces a set of coupled Dirac equations that describe neutrino flavor oscillations, and we make use of this to establish a connection with neutrino phenomenology, thus allowing to fix the parameters of the simulation for a given neutrino experiment. We also analyze how matter effects for neutrino propagation can be simulated in the quantum walk. In this way, important features, such as the MSW effect, can be incorporated. Thus, the simulation of neutrino oscillations with the help of quantum walks might be useful to explore the…

PLASTICS RECOVERY FROM MUNICIPAL WASTE: MAINSTREAMS AND BY-PRODUCTS IN A CASE STUDY IN NORTHERN ITALY.

2014

In the case study dealt with here, the factory treatments of dry Municipal Solid Waste are aimed primarily at materials recovery; restraining energy recovery to the hardly recyclable by-products. The main input consists of the so-called multipak from MSW source-sorted collection; plus packaging waste, paper and cardboard and other similar waste from curb-side collection. The principal fractions produced by the selection plant, own and operated by the Public Company in charge of MSW management, in the Year 2012 were 27 064 tonnes of plastics, 5 066 of paper, 3 014 of tin coated steel and 4 886 tonnes of extraneous fraction to dispose of. A minor – though valuable – product was aluminium. The…

Green small technology for neighbourhood regeneration: a southern case-study.

2012

I rifiuti possono trasformarsi da problema ad opportunità se si transita da un’amministrazione del consumo e dello spreco ad una gestione che si proponga l’ottimizzazione nell’uso delle risorse e la valorizzazione degli scarti. Il trattamento della frazione organica dei rifiuti per la produzione di biogas, calore di processo e compost di qualità può rappresentarne un aspetto di forte rilievo. La scala di quartiere, indicata nel lavoro di ricerca che viene presentato, può consentire, per certi versi, la scomposizione della complessa realtà metropolitana e la declinazione efficiente del paradigma del principio di prossimità, dell’autosostentamento e del coinvolgimento delle comunità locali pe…

Environmental assessment of the Sibiu County, Romania: proposal for sewage sludge and OFMSW management

2017

The aim of the work is to assess current solid waste management (SWM) and wastewater treatment (WWT) in the county of Sibiu, Romania. Sibiu is a region where industrialization and tourism are spreading constantly, while pollution monitoring and the introduction of circular economy (CE) principles are still lacking. The environmental issues are mostly due to the absence of reliable sanitation systems, in particular for what concerns sewage sludge treatment. Moreover, Organic fraction from selective collection of municipal solid waste is still missing, since it is disposed of directly to landfill, increasing environmental pollution and contributing considerably to global warming. As a result,…
