Batch Test Evaluation of Four Organic Substrates Suitable for Biological Groundwater Denitrification
2014
Nitrates pollution represents nowadays a serious issue related to the quality of groundwater; continuous growth of industrial-scale agricultures lead to an increase of nitrates content in groundwater in the last years. Several technologies have been validated as capable to promote in situ biological nitrates remediation, such as permeable reactive barriers (PRB), biotrench, biobarriers etc. These technologies are all characterised by the use of organic substrate that act as a slow release carbon source. In free dissolved oxygen absence, such organic carbon is further oxidised, by heterotrophic bacteria naturally present in soil, in compliance to anoxic metabolism by using nitrates bound oxy…
Mathematical Modelling of In-sewer Processes as a Tool for Sewer System Design
2018
The objective of this paper is to evaluate the potential impact of in-sewer processes (COD components transformation and hydrogen sulphide production) on the design of sewer systems. The tool used for such analysis is a mathematical model derived from the WATS model (Wastewater Aerobic/anaerobic Transformation in Sewers) able to describe the processes occurring in the sewer system both under aerobic and anaerobic conditions. The model is applied to three synthetic catchments with, respectively, 10,000, 50,000 and 250,000 inhabitants connected to gravity sewer systems different in terms of type (separate or combined), slope, length, travel time, wastewater temperature. The simulation results…
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…
Bioresource technology for bioenergy, bioproductsenvironmental sustainability.
2022
The 3rd International Conference for Bioresource Technology for Bioenergy, Bioproducts & Environmental Sustainability (BIORESTEC) was held online from 17 to 19 May 2021. More than 120 participants from all over the world participated in this conference. The conference was studded with nine plenary lectures, ten invited lectures as well as more than 50 oral presentations along with several poster presentations. The purpose of the conference was to foster the exchange of knowledge and ideas among researchers in academia and industry as well as policymakers working on various aspects of biorefinery to discuss the progress made during the intervening three years and the latest trends in bio…
Analisi di processo e dinamica della comunità batterica nel trattamento di sedimenti marini con reattori bioslurry
2020
Nella nota sono riportati i risultati di una sperimentazione condotta mediante la messa in esercizio di un reattore bioslurry per il trattamento di sedimenti marini contaminati da idrocarburi. Sono state valutate le performance di processo in termini di rimozione di TPH (86% con velocità di rimozione massima di 36 mgTPH kg-1 d-1) congiuntamente ad altre tipologie di indagini volte ad ottenere maggiori informazioni sulla natura dei processi che si sono sviluppati nel reattore. Nello specifico, è stato utilizzato un approccio di tipo microbiologico mediante l’adozione di una tecnica di sequenziamento di nuova generazione (NGS - Next Generation Sequencing). Dall’analisi dei dati biologici è st…

Environment, wealth, inequality and the burden of disease in the Accra metropolitan area, Ghana
2005
The study examines environmental problems and adverse impacts on the health of urban households in the Accra metropolitan area, Ghana. Accra is faced with severe inadequacy of urban infrastructure in the face of rapid population growth in the metropolis. More than half of the city's population do not have access to solid waste collection services. Only 39.8% of households have indoor pipe and over 35.0% of households depend on unsanitary public latrines whilst 2.5% do not have access to toilet facilities. Human excrement, garbage and wastewater are usually deposited in surface drains, open spaces and streams in poor neighbourhoods. The resultant poor sanitation has serious health impacts as…
Motivazione e Burnout
2004
Working activities are subjected to different relationship and motivational dynamics which may cause stress and behavioural disorders. Burnout syndrome was indicated as strictly related to motivation and satisfaction in socio sanitary activities.
LA QUALITA' RELAZIONALE IN UNA RESIDENZA SANITARIA ASSISTENZIALE: IL PUNTO DI VISTA DEI CAREGIVER

La vaccinazione antinfluenzale come Strumento di Sanità pubblica e di prevenzione. Esperienza dell'Azienda Ospedaliero Universitaria Policlinico (AOU…
2009
Introduzione Le Linee guida per la prevenzione e controllo dell'influenza, emanano Ogni anno dal Ministero della Salute, raccomandano la vaccinazione per tutti Coloro Che svolgono Funzioni lavorative di primario interesse collettivo. Il personale sanitario rappresenta, un tal Riguardo, un obiettivo strategico della campagna da vaccino antinfluenzale SIA per la possibile trasmissione dell'influenza aviaria Pazienti SIA Perchè l'eventuale assenteismo Potrebbe inficiare la qualità e la Capacità dell'Assistenza erogata. La trasmissione dell'influenza ad un Paziente è sicuramente un importante Rischio nosocomiale in Quanto l'Infezione virale PUÒ portare ad un aggravamento dello stato di salute d…
