Economical evaluations of reactive power supply as an ancillary service offered by distributors

2006

Reactive power supply is one of the most important ancillary services in the field of transmission systems safety. In the current market assets, at international level, this service is differently regulated and sometimes with criteria that are not market driven. The present work is focused on the perspective to realise a reactive power market to which also the distributors can take part injecting reactive power into HV/MV connection bus bar. Under this hypothesis, the paper proposes a methodology to evaluate the economic convenience limits that the system operator would have buying the capacitive reactive power offered by distributors.

Second Opinion System for Intraoral Lesions

2014

In this paper we present the prototype of a teledentistry system to perform the remote diagnosis of oral diseases. It makes use of a particular device called intra-oral (or dental) camera properly designed to shoot video and take pictures of the inner part of the mouth. The intra-oral cameras can be connected via USB to a common PC and they are very cheap, unlike the intra-oral photography kit for DSLR cameras. Usually this kind of devices are used in dentistry studies for local visualization by means of specialized software. The novelty of our system is that the real-time video produced by this device is canalized into a video streming by means of Video LAN client server (VLC) and pictures…

Aloe-Based Edible Coating to Maintain Quality of Fresh-Cut Italian Pears (Pyrus communis L.) during Cold Storage

2021

Pear fruits are known for their antioxidant and nutritional characteristics. However, they are very susceptible to rapid decay. Edible coating (EC) represents a good strategy to maintain postharvest quality. The effects of two EC in slowing down the senescence processes in fresh-cut ‘Coscia’ pears were investigated: EC1 (A. vera gel, hydroxypropyl-methylcellulose and pomegranate seeds oil (PSO), EC2 (A. vera gel and hydroxypropyl-methylcellulose). Weight loss, firmness and colour decrease more slowly in both EC-treated than in untreated (CTR) slices; soluble solid content increases faster in CTR, indicating a faster ripening process. The specific investigation of undesired microorganisms di…

The agricultural heritage of Lampedusa (Pelagie Archipelago, South Italy) and its key role for cultivar and wildlife conservation

2011

As occurred on many other little Mediterranean islands, agricultural activity at Lampedusa (Strait of Sicily) underwent a very strong decline in terms of surface area during the second half of the last century. In particular, cereal crops have ceased and horticulture is disappearing, while vineyards still occupy a reduced area but are quickly vanishing and currently survive thanks to a small number of old farmers. Here are presented the results of a research carried out by interviewing seven farmers in order to study not only the techniques and the germplasm used in local viticulture, but also the final use of grapes and an evaluation on the connection between traditional farming and agro-e…

Impiego del sofosbuvir nel trattamento del virus da epatite C, in pazienti ospedalizzati presso l’Istituto Mediterraneo per i trapianti e terapie ad …

2015

Introduzione: L’epatiteC è stata generalmente trattata con PEGinterferone associato alla Ribavirina per un periodo di 24-48 settimane in funzione del genotipo. L’Azienda Gilead ha sviluppato un antivirale per il trattamento dell’infezione cronica da HCV: il Sofosbuvir GS-7977. L’ISMETT di Palermo ha avviato nel 2014 l’utilizzo per i propri pazienti. Il farmaco verrà fornito gratuitamente dalla stessa azienda farmaceutica grazie al DM 8/5/2003. Materiali e Metodi: Sono state valutate le cartelle cliniche informatizzate e condotta una ricognizione bibliografica su Pubmed e bancadati AIFA. Risultati: I candidati al trattamento con Sofosbuvir sono pazienti con cirrosi epatica HCV+ in lista d’at…

Sintesi e caratterizzazione allo stato solido ed in soluzione di derivati chinolonici di organostagno(IV)

2008

I chinoloni sono antibiotici, recentemente usati anche come chemioterapici. Tra i derivati dell’acido nalidixico, precursore di tutte le classi di chinoloni, sono stati scelti chinoloni di I e II generazione per la sintesi di derivati di diorganostagno(IV). Questi composti sono stati caratterizzati sia allo stato solido che in soluzione con spettroscopia FT-IR, Mössbauer, 1H NMR, e con spettrometria di massa (ES-MS).

Synthesis, Characterization and in vitro antimicrobial activity of dialkyltin(IV)bis(fusidate) complexes.

2008

The complexation of one steroid antibiotic of the fusidane family, sodium fusidate [sodium 2-16-acetyloxy-3,11-dihydroxy-4,8,10,14-tetramethyl-2,3,4,5,6,7,9,11,12, 13,15,16-dodeca hydro-1H-cyclopenta[a]phenanthren-7-ylidene)-6-methyl-hept-5-enoate = (Nafus)], by dialkyltin(IV) has been studied by conventional technique as FT-IR, Mössbauer and NMR spectroscopies. Analytical data supported the general formula Alk2Sn(IV)fus2 (Alk = Me, Bu). Infrared spectral data of the complexes imply the presence of both uni- and bidentate, ester-type and bridging carboxylate group, respectively. On the basis of FT-IR and 119Sn Mössbauer spectroscopy, in both Me2Sn(IV)fus2 and Bu2Sn(IV)fus2, trigonal bipyram…

Organotin(IV)derivatives neurotoxicity and their modulation by Baclofen

2008

Several new diorganotin(IV) and triorganotin(IV) complexes with 4-amino-3- (4-chloro phenyl)]-butanoic acid ( = Baclofen) have been synthesized and their structure investigated both in the solid state and in solution phase through spectroscopic methods (FT-IR, Mössbauer, 1H and 13C NMR). According to experimental analytical data, the stoichiometry of the complexes has been proposed as R2SnBac2 and R3SnBac, respectively for diorganotin(IV) and triorganotin(IV) baclofen complexes. (Baclofen = HBac; R = Me, Bu, Ph).

CO-TREATMENT OF LANDFILL LEACHATE IN SBR SYSTEM: LAB-SCALE CASE STUDY REPORT

2015

SUMMARY: Landfill leachate represents nowadays one of the most controversial topics in the waste management cycle. A possible alternative for treating aged landfill leachate is represented by the co-treatment with municipal wastewater (MWW) that provides the necessary amount of biodegradable substances to enhance the development of bacteria metabolism. The correct tradeoff between landfill leachate and MWW represent a key factor in order to avoid inhibition of biomass activity. The paper reports the results of an experimental research carried out on two lab-scale Sequencing Batch Reactors (SBRs) fed with synthetic wastewater and landfill leachate in different percentages (SBR1 fed with 20% …
