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…
Multivariate analysis of sites using water invertebrates and land use as indicators of the quality of biotopes of Mediterranean relic plant (Petagnae…
2007
Petagnaea gussonei is a rhizomatous, perennial scapose hemicryptophyte species belonging to a monospecific genus of Apiaceae. It lives only along woodland rivulets and is a Tertiary relic localized in the restricted area of the Nebrodi Mountains (NE Sicily, Italy). Ecological indicators have been employed to understand the status of eight localities (intermittent rivulets) where the species occurs. In order to evaluate both the rivulets' water-quality and landscape use, index of anthropisation (Ia), water fleas bioassay (TU), and analyses of water macroinvertebrates have been employed. The results obtained for the level of toxicity exclude the presence of macropollutants (TU < 0.001), where…
An Anthropometric Analysis of Seated and Standing People
2012
Thermal radiative exchanges of the human body with surrounding surfaces play an essential role in describing the thermal conditions of people in a given environment. Moreover, they could be induced by, among other causes, the presence of high intensity radiant sources, like lighting spots or infrared heating panels. This implies that a suitable set of radiation data related to human body anthropometry is required. This set of data mainly comprises the body surface area, the clothing area factor, the effective radiation area factor, and projected area factors. Several analytical or experimental methods may be utilized in order to compute these parameters. A detailed description of the most c…

Studio botanico finalizzato al recupero del paesaggio vegetale dell’Area archeologica di Lilibeo presso Marsala (Sicilia occidentale)
2013
Viene presentato uno studio botanico volto al recupero del paesaggio vegetale dell’Area Archeologica di Capo Lilibeo (Marsala). Il progetto prevede l’eradicazione delle specie esotiche ad alto grado di invasività quali Ailanthus altissima e Vachellia karroo, il risanamento fitosanitario dei viali di Palme delle Canarie e la sostituzione degli individui malformati con specie ornamentali altamente decorative e a basso grado di invasività. E’ previsto l’impiego di specie afferenti agli stadi più evoluti dei sigmataxa Chamaeropo humilis- Querceto calliprini sigmetum ed al Pistacio lentisci- Chamaeropo humilis sigmetum al fine di assicurare i migliori risultati contro l’espansione della componen…
Floristic and phytosociological features of the Brachypodium rupestre communities in Italy
2018
The pale green dense Tor-grass (Brachypodium rupestre) tufts are a quite distinctive aspect of the Italian grassland pattern of the colline and submontane belts. B. rupestre is used to be found in secondary grasslands both in natural environments and in some aspects of the post-coltural environments such as forest clearances, abandoned terraced and extensive pastures. In northern Italy (Alps, Prealps and northern Apennines) B. rupestre has only sporadically been considered in the grasslands syntaxonomic frameworks. On the contrary it occurs in those regarding the central Italy where several semi-natural and post-coltural grassland associations (e.g. Polygalo flavescentis-Brachypodietum, Gal…
Introduction to the study of the bryological flora of the Batumi Botanical Garden (Georgia)
2021
A preliminary list of 22 bryophytes growing in the Batumi Botanical garden is provided. From chorological point of view, temperate and boreo-temperate taxa prevail while with regard to ecological behaviour, mesophilous taxa are the most numerous and with respect to light requirements equivalently sciaphilous and eliophilous taxa are represented. The mosses Fissidens dubius and Cyrtomnium hymenophylloides are recorded for the first time in Georgia.
