URBAN RESILIENCE AND WASTE MANAGEMENT: PROPOSALS OF NEW INFRASTRUCTURES FOR URBAN AREAS AND BUILDINGS
2015
La produzione ingente di rifiuti, quale conseguenza di costumi di vita volti allo spreco, rende vulnerabili i sistemi urbani che possono essere sottoposti, in casi emergenziali, a pressioni eccezionali e incontrollate con situazioni prossime al collasso. Un’opportuna e corretta gestione integrata dei rifiuti contribuisce alla resilienza dei sistemi urbani. Perciò si rendono necessarie la pianificazione e la progettazione di nuovi servizi e l’individuazione/integrazione di spazi e dotazioni tecnologiche per incentivare la popolazione a effettuare la raccolta differenziata in modo corretto e costante. Si presentano gli esiti di uno studio svolto in un piccolo centro siciliano. Partendo dalle …
Edilizia abusiva a Favara. Analisi dell’insediamento e sviluppo del territorio
2007
Il Piano Regolatore Generale, strumento di fondamentale importanza per lo sviluppo di un centro urbano e del suo territorio, è ancora per diverse città siciliane un obiettivo da raggiungere. I dati provenienti dall'Assessorato Regionale al Territorio e Ambiente (A.R.T.A.) indicano una Sicilia decisamente indietro nella progettazione urbanistica. Nell'isola soltanto il 40,3% dei comuni hanno un piano regolatore vigente. La mancata approvazione degli strumenti urbanistici ha influito negativamente sui processi di urbanizzazione, spesso frammentari e disorganici. Le città si sono sviluppate senza una forma, un modello riconoscibile, alimentando nei cittadini una politica che ha preferito l’edi…
Identification and isolation of the primary aggregation factor from the cell membrane of the sponge Geodia cydonium
1985
The primary aggregation factor (pAF) of sponge cells is a glycoprotein that is firmly associated with the cell membrane. Polyspecific antibodies (anti-GM) prepared from sera raised against membranes of cells from the siliceous sponge Geodia cydonium were found to inhibit initial aggregation of homologous cells. The inhibition of aggregation, caused by anti-GM was neutralized by pAF. The pAF had been successfully solubilized and enriched by affinity chromatography, gel filtration and density gradient centrifugation, if checked by polyacrylamide gel electrophoresis in the presence of urea. The Mr of the native pAF was approximately 40 000 as estimated by gel filtration; under denaturing condi…
Extending customer relationship management. From empowering firms to empowering customers
2013
Purpose – The focus of customer relationship management (CRM) literature has been predominantly on the firm perspective and on IT, not on customer or service orientation and value co-creation. This paper seeks to explore and analyse contemporary CRM frameworks and suggests future research directions. To achieve this, a thorough literature review on CRM is conducted focusing on recent advances within CRM. This provides a good basis for critically analysing the current status of both CRM theory and practice. Design/methodology/approach – The paper reviews CRM literature published 2003-2011. Based on the literature review, it introduces a conceptual framework of the changing role of customer d…

Darbā analizēti kodolsintēzes reaktora, Apvienotā Eiropas Tora (Joint European Torus – JET) vakuuma kameras erozijas produkti. Izmantojot fizikāli ķīmiskas analīzes metodes – infrasarkanās, elektronu spinu rezonanses, Ramana, enerģijas dispersijas rentgenstaru spektrometrijas, skenējošās elektronu mikroskopijas un termodesorbcijas metodes, noteikti erozijas produktu daļiņu izmēri, ķīmisko elementu sadalījums tajās, paramagnētiskie centri un tritija izdalīšanās no erozijas produktiem, kā arī salīdzināts ar vakuumakamerā neizmantou materiālu un putekļiem no divertora ķieģeļa tilpuma. Pēc paramagnētisko centru sadalījuma erozijas produktos un divertora materiālā, spriest, ka metālu oksīdi nepi…
Quantification of bacterial subgroups in soil : comparison of DNA extracted directly from soil or from cells previously released by density gradient …
2001
All molecular analyses of soil bacterial diversity are based on the extraction of a representative fraction of cellular DNA. Methods of DNA extraction for this purpose are divided into two categories: those in which cells are lysed within the soil (direct extraction) and those in which cells are first removed from soil (cell extraction) and then lysed. The purpose of this study was to compare a method of direct extraction with a method in which cells were first separated from the soil matrix by Nycodenz gradient centrifugation in order to evaluate the effect of these different approaches on the analysis of the spectrum of diversity in a microbial community. We used a method based on polymer…

Condylar position indicator and T-scan system II in clinical evaluation of temporomandibular intracapsular disease.
2012
The pathogenesis of temporomandibular joint intracapsular disease (TMJI) is multifactorial and its diagnosis is not easy. In this work authors show two types of clinical analysis: the Condylar Position Indicator (CPI) and T-Scan 2 system.Twenty patients (mean age of 24.5 years) with TMJI problem and 10 healthy matched subjects (mean age: 25.4 years) were selected. Analysis of TMJI was performed on each patient by means of Condylar Position Indicator (CPI) and T-Scan System II tests.Eight patients presented vertical symmetrical condylar distraction greater than healthy subjects (P-value0.001). T-Scan showed a difference of Percentage of Force (POF) not greater than 5%. Seven patients showed …
Separation of deoxyribonucleases (DNases) of normal human stratum corneum and psoriatic scales by micro-disc-electrophoresis.
1975
Normal stratum corneum and psoriatic scales were homogenized and a differential centrifugation was performed. The DNase activity of the individual fractions was investigated by micro-disc-electrophoresis. At pH 5 only in the 600 × g pellet and 105.000 × g supernatant of normal keratin DNase activity could be observed. However, all psoriatic fractions showed distinct enzyme activities. At pH 7.4 little psoriatic DNase activity could only be demonstrated in the 105.000 × g supernatant. Except from the 15.000 × g pellet all fractions of normal stratum corneum displayed marked activities. In addition the 105.000 × g supernatant showed two different DNase bands.
