Kristiansson, Louise. "Chemical Bleaching of Wood and Its Aging : An Investigation of Mahogany, Walnut, Rosewood, Padauk and Purpleheart." Thesis, Linköpings universitet, Carl Malmsten - furniture studies, 2012. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-78510.
Full textAbstract:
This paper investigates chemical bleaching of wood and its ageing to make specie specific recommendations on which bleaching solutions to use when color adjusting veneer for furniture restoration. In more detail, chemical bleaching of European walnut (Juglans regia), Rio rosewood (Dalbergia nigra), purpleheart (Peltogyne spp.), Honduras mahogany (Swietenia macrophylla) and padauk (Pterocarpus spp.) has been investigated using eleven different bleaching solutions. Both oxidative (e.g. hydrogen peroxide and potassium permanganate) and reductive (e.g. oxalic acid and sodium bisulfite) solutions have been used. Furthermore, to investigate aging of the bleached surfaces they were subjected to sunlight behind a glass window until a change in Blue Wool Scale 3 was obtained. Visual examination has been used to rank the color change after the chemical bleaching and the sun light exposure experiment. A small color change after the sun light exposure experiment indicates a high degree of lightfastness and is preferred for long term stability when restoring furniture. The results show that the wood species react in different ways to the investigated bleach solutions and to sun light exposure. It can also be noted that all investigated solutions were not suitable for all wood species. Moreover, the sun light exposure experiment identified effective bleach solutions that gave an unacceptable low lightfastness for mahogany and padauk after chemical bleaching. Based on the chemical bleaching and sun light exposure results, preferred bleaching solutions are recommended for the investigated wood species.<br>En vanlig restaureringsuppgift är att ställvis ersätta borttappat träfaner på en möbel. Originalfaneret har blekts med tiden, varför det nya faneret ofta är för färgstarkt och färgen behöver reduceras. När vi upplever en bit padouk som intensivt röd eller amarant som lila, beror det på att det i trät finns ämnen som tar upp energi motsvarande energin i våglängder av synligt ljus. När ämnena absorberar en del av det synliga ljuset registrerar våra näthinnor att de saknas, vilket tolkas som en färg av vår hjärna. De ämnen som absorberar synligt ljus kan brytas ner av solljus över längre tid eller på några minuter genom tillförseln av ett oxidations- eller reduktionsmedel. I mitt examensarbete undersöker jag hur olika oxidations- och reduktionsmedel bleker olika träslag. Jag har valt att undersöka hondurasmahogny, europeisk valnöt, brasiliansk jakaranda, padouk och amarant, då det är träslag som ofta behöver blekas när de används i kompletteringar. Vidare undersöker jag hur den genom blekning erhållna färgen i trät i sin tur påverkas av solljus. Detta är viktigt för att förstå hur de restaurerade delarna på möbeln kommer att åldras. De viktigaste resultaten sammanfattas nedan: Valnöt, jakaranda och amarant reagerade på liknande sätt vid kemisk blekning med de i studien använda lösningarna. De blekas mest av natriumhydroxid och salter med väteperoxid. Mahogny och padouk reagerade på liknande sätt vid kemisk blekning. De blektes mest, med ett jämnt resultat, av väteperoxid med natriumhydroxid eller ammoniak. Oxidationsmedel blekte effektivare än reduktionsmedel. Enbart väteperoxid gjorde jakaranda mörkare. En hög ammoniakkoncentration gav blekare resultat än en låg på alla träslag utom amarant. Valnöt var mest ljusäkta av de undersökta träslagen. Majoriteten av mahognyproverna mörknade av solljusexponeringen. Jakaranda och padouk blektes av solljusexponeringen. Flertalet amarantprover mörknade och ett mindre antal blektes av solljusexponeringen. Solljusexperimentet identifierade blekningslösningar som gav oacceptabelt låg ljusäkthet på mahogny och padouk. För effektiv blekning och godtagbar ljusäkthet rekommenderas följande lösningar för respektive träslag. Välj lösning beroende på önskad blekningsgrad (se Tabell 2 sid 10). Mahogny: väteperoxid, oxalsyra eller kaliumpermanganat och natriumbisulfit. Valnöt: väteperoxid med eller utan ammoniak, väteperoxid och natriumhydroxid med eller utan salter eller natriumbisulfit och oxalsyra. Jakaranda: väteperoxid med ammoniak, oxalsyra, väteperoxid och natriumhydroxid med eller utan salter, natriumbisulfit och oxalsyra eller kaliumpermanganat och natriumbisulfit. Padouk: natriumhydroxid, natriumsilikat och kalciumhydroxid följt av väteperoxid. Amarant: väteperoxid med eller utan ammoniak, väteperoxid och natriumhydroxid med eller utan salter eller kaliumpermanganat och natriumbisulfit.

Full textAbstract:
Nel presente studio sono state eseguite analisi chimiche su sedimenti fluviali, prelevati in 233 siti rappresentativi, fra i corsi d'acqua che attraversano la pianura Padana. L'obbiettivo dello studio era di caratterizzare il sedimento e determinarne il suo stato di qualità. Parallelamente è stata effettuata, un'indagine sulle comunità di macroinvertebrati, fra alcuni degli affluenti di sinistra del Po e sul Po stesso. I sedimenti sono stati analizzati con uno spettrofotometro a fluorescenza a raggi x (XRF). I risultati ottenuti, durante le analisi e le elaborazioni cartografiche eseguite, vengono riportati e discussi in questo documento. Le analisi chimiche indicano che la composizione del sedimento è caratteristica secondo la sua provenienza ed è determinata dalla litologia dell'area che i fiumi attraversano. Sono state riscontrate particolari anomalie, delle concentrazioni di alcuni elementi potenzialmente tossici, a valle dei centri urbani. Lo studio delle comunità di macroinvertebrati concorda con i risultati ottenuti attraverso le analisi chimiche.

Full textAbstract:
Gli eventi sismici del 2012 in Emilia-Romagna hanno provocato una rinnovata attenzione su alcuni fenomeni di carattere geologico superficiale. Sono stati in particolare riferiti dalla stampa locale e osservati dagli abitanti gorgogliamenti di gas naturale nelle acque dei pozzi, nelle acque dei canali di bonifica ed emissioni di gas libero, in prevalenza metano. In questa tesi si è voluto mettere in luce tutto lo sviluppo storico del metano Padano, facendo un particolare riferimento al metano più superficiale, ossia al metano denominato biogenico, illustrando le sue origini, le sue prime manifestazioni, la sua scoperta, la sua derivazione dalla torba, le sue prime produzioni, considerando gli impatti ambientali possibili e verificati, arrivando fino all’attuale periodo in cui esso si è affermato diventando una delle fonti principali di energia ed una delle materie prime più preziose.
La Tesi ha lo scopo di meglio chiarire l’origine e la modalità di occorrenza del metano biogenico Padano. Viene inoltre sviluppata una indagine orientata a identificare gli orizzonti geologici più “produttivi” di metano biogenico della regione Emilia-Romagna originato da torbe. Le aree effettivamente più produttive sono una parte di quelle ricche in torba e sono caratterizzate da buone capacità di conservazione nel tempo delle caratteristiche chimico fisiche favorevoli alla degradazione batterica della sostanza organica. Ciò avviene quando vengono mantenute particolari condizioni di isolamento tramite argille ecc. Il metano biogenico Padano viene costantemente espulso dai sedimenti e naturalmente disperso in atmosfera. Eventuali attività di captazione del metano dalle aree maggiormente produttive potranno contribuire alla diminuzione dell’effetto serra e alla contestuale produzione a piccola o piccolissima scala di energia nei limiti delle normative in vigore soggette ad eventuali possibili revisioni in analogia a quanto disposto per altre forme di generazione di metano come biogas, discariche ecc.

Ashar, Faisal. "Tsunami evacuation planning : case study in Padang City, Indonesia." Thesis, University of Huddersfield, 2018. http://eprints.hud.ac.uk/id/eprint/34590/.
Full textAbstract:
Padang city is a coastal city in Sumatra. Padang is the region that is most likely to be devastated by a tsunami that may occur in the near future. The research estimated that the arrival of a tsunami (ETA) in Padang city could be about 20-30 minutes. Padang city is situated on the very flat liquefiable ground, with approximately 800,000 people in which 50% of residents live in tsunami inundation area. Therefore, it would be difficult to evacuate almost 400,000 people in a short time to a safe tsunami zone. There would not be enough time for people to reach a safe or higher place. The local government has made various efforts to develop local early warning systems and disaster management. These activities include preparing legislation, preparing evacuation infrastructure, building shelters, and preparing resources for government officials and for the community, and other support activities that must be done to anticipate the tsunami hazard. It is recognized that the provision of all infrastructure for evacuation requires a longer period, and is not an easy thing to do considering that Padang city is not a prosperous city, and it has low revenue. In the light of the condition, Padang city needs a tsunami evacuation planning. This study aims to evaluate the process of tsunami evacuation planning in Padang city, Indonesia. The evaluation will be through measurement and assessment of a disaster preparedness index of tsunami evacuation, with the assessment object given by the government and society. To achieve the aim and the objective of the research, the single case study is selected. This study implements a mixed method application, with semi-structured interviews and a questionnaire survey. Content analysis is used to analyse qualitative data, and the descriptive statistics technique is used to examine quantitative data. Based on the results of the survey, it is known that the knowledge of individuals in Padang city is apparently good. It is comprehended by their ability to understand the meaning of the tsunami disaster, the causes of the earthquake and tsunami and their characteristics. Mosque in tsunami zone is the basis in tsunami preparedness, because it has many advantages among them: as a vertical tsunami shelter, as a shortest-fastest way, as a facility to disseminate disaster/EWS and as a facility to educate students. People who work in BPBDs will stay/permanently there for five years. If the displacement remains the case, at least BPBD can recommend an employee who has the capacity in disaster and participates in a forum on the disaster in Padang city. Tsunami evacuation maps must be reviewed, both from the number of maps distribution and the ability and willingness of the public to read maps, the effectiveness of the placement of maps at the intersection and the road.

Full textAbstract:
Il suolo è soggetto all’attacco di svariati contaminanti rilasciati nell’ambiente da parte dell’uomo, fra questi troviamo i metalli pesanti. Alcuni metalli pesanti risultano tossici per organismi animali e vegetali se superano certe soglie di concentrazione. Nei suoli i metalli pesanti si trovano sia per cause naturali che antropiche. La fonte naturale dei metalli è legata alla struttura, composizione mineralogica, granulometrica dei sedimenti, e al grado di alterazione dovuta ai vari processi pedogenetici da cui è nato il suolo. In questo lavoro di tesi ho realizzato un campionamento che fosse rappresentativo dell’area presa in esame. In base alle geologia della zona, sono state individuate 32 stazioni dove è stata effettuata la perforazione, ottenendo un totale di 58 campioni. Lo scopo di questa tesi consiste nella determinazione e caratterizzazione cartografica del contenuto dei metalli pesanti nei suoli posti a ovest di Mantova. Per ogni campione è stata eseguita l’analisi per la determinazione del contenuto totale degli elementi maggiori e di quelli in traccia tramite fluorescenza a raggi X (XRF) ,il calcolo della LOI. Dai dati ottenuti dall’analisi XRF è stato applicato l’indice di geoaccumulo, il quale ha fornito il livello di arricchimento superficiale per Cromo, Nichel, Rame, Zinco, Piombo, Arsenico e Vanadio, permettendo di effettuare una stima della contaminazione puntiforme dell’area. Lo studio si è concluso con la realizzazione di mappe di concentrazione di metalli pesanti. La creazione di mappe pedogeochimiche diviene sempre più importante per una completa gestione territoriale ed ambientale.

Full textAbstract:
Il suolo, oltre a rappresentare la base su cui si sviluppa la vita, è anche il luogo in cui si sviluppano l’industrializzazione, le reti viarie, i commerci; è quindi sottoposto a continue pressioni di tipo antropico che inducono modificazioni chimiche, biologiche della sua composizione.
I metalli pesanti sono tra i più importanti inquinanti del suolo, sebbene siano presenti all’interno di esso come materiale costituente, le loro concentrazioni possono aumentare a causa di immissioni antropiche, modificando quindi la struttura del suolo rendendolo inquinato. In questo lavoro di tesi, avente come area d’interesse una porzione della provincia di Mantova precisamente ad est della città e parte della provincia di Verona e Rovigo si è voluto analizzare le caratteristiche composizionali dei suoli, al fine di determinare situazioni di arricchimento imputabili o all’uso del suolo o all’origine del sedimento. A questo proposito si è ritenuto opportuno impostare un confronto tra le concentrazioni totali dei metalli in superficie e quelle in profondità, questo non è stato sempre possibile in quanto la litologia dell’area non ha permesso, in alcuni casi, il prelievo del campione profondo. I suoli sono stati sottoposti ad analisi per il contenuto totale degli elementi maggiori e in traccia tramite analisi XRF, è stata poi eseguita la Loi per determinare la percentuale di perdita della materia organica, applicato l’indice di geoaccumolo ed infine sono state create grazie all’ausilio del software Qgis mappe di concentrazione di metalli pesanti quali Cromo, Nichel, Rame, Zinco, Piombo, Arsenico e Vanadio relative all’area di interesse di questo lavoro di tesi.

Full textAbstract:
Au cours de ce travail, le taux d’extractibles de cinq essences camerounaises a été évalué par la technique d’extraction accélérée ASE 200 et au Soxhlet. Le taux d’extractibles varie de 4,4 à 17,7%. Le screening des extraits a révélé la présence de polyphénols, de saponines, de flavonoïdes, de stérols et de terpènes. Les phénols totaux contenus dans les extraits ont été évalués par la méthode de Folin–Ciocalteu en utilisant l’acide gallique comme standard. La teneur varie de 16,5 à 165,83 mg éq acide gallique / g d’extrait. Le dosage des tannins condensés par la méthode colorimétrique a permis de montrer que ces derniers varient de 0,15 à 23,61 g cyanidin équivalents / 100 g de matière sèche. L’identification des composés contenus dans les extraits par GC-MS a permis d’identifier de l’homopterocarpine et de la pterocarpine dans les extraits de padouk. Les extraits de tali contiennent de la catéchine, l’acide gallique et du pyrogallole. L’acide gallique, le squalène et les triterpènes sont les composés majoritairement identifiés dans les extraits de movingui. La durabilité naturelle des bois a été évaluée par la norme européenne EN 350-1, 1994. Il ressort que les pertes de masse deviennent plus importantes lorsque les éprouvettes de bois ont été extraites. La perte de masse des éprouvettes non extraites varie de 0,1 à 59% (le hêtre a été pris comme référence). Les essais d’inhibition de croissances sur les champignons de pourriture ont montré qu’à des concentrations de 250 ppm, nos extraits étaient fongistatiques et qu’à des concentrations de 500 ppm certains extrait étaient fongicides (extrait de tali). L’évaluation des propriétés antioxydante et colorante des extraits pour envisager de potentielles applications industrielles a été effectuée. Le pouvoir antioxydant des extraits a été évalué par la méthode d’inhibition du linoléate de méthyle induite par l’azobisisobutyronitrile (AIBN). Les résultats obtenus sont satisfaisants car l’activité antioxydante varie de 10 à 86%. Le pouvoir anti-radicalaire des extraits a été évalué en utilisant le radical 2,2-diphényl-1-picrylhydrazyl (DPPH.). Les concentrations nécessaires pour consommer 50% du radical varie de 2,7 à 60,5 mg/L. La capacité des extraits aqueux et alcalins à teindre les fibres naturelles et artificielles a été évaluée. La mesure de la coloration prise par les fibres s’est faite à l’aide d’un colorimètre Datacolor D65°10. Les résultats montrent que ces extraits donnent une coloration jaune avec les extraits de movingui et une coloration rouge avec les extraits de padouk. L’utilisation des extraits pour inhiber la croissance bactérienne a montré que les extraits étaient bactériostatiques pour les concentrations testées<br>In this work, the accelerated technical ASE 200 and Soxhelet was used to evaluate the amount of extractives contained in five Cameroonian wood species. The amount of extractives ranged from 4.4 to 17.7% with respect to oven-dry matter. Phytochemical screening of the extractives revealed the presence of polyphenols, saponins, flavonoïds, sterols and terpenes. The total phenolic content of the extracts was measured by the Folin-Ciocalteu method using gallic acid as standard. The phenolic content ranged from 16.5 to 165.83 mg eq gallic acid/g of extract. The condensed tannins, evaluated by colorimetric method, ranged from 0.15 to 23.61 g cyanidin equivalents/100 g of dry matter. GC-MS identified the homopterocarpine and pterocarpin as major compound in extracts of padouk. Catechin, gallic acid and pyrogallole were the major compounds found in the extracts of tali. Extracts of movingui consisted mainly of diterpenes and several compounds not readily identifiable. Gallic acid, squalene and triterpenes were the predominant compounds identified in the extracts of movingui. The natural durability of wood was evaluated using the European Standard EN 350-1. Mass losses increased when the wood samples were extracted. Mass losses of non-extracted samples ranged from 0.1 to 59% (with beech taken as a reference). The effect of extractives on fungal growth showed that at 250 ppm concentrations, the extracts were fungistatic and that at 500 ppm concentrations, the extracts of tali were fungicidal.Valorization of the extractives in the food and the textile industries was attempted. In food, the antioxidant activity of the extracts by inhibition of methyl linoleate induced by AIBN was evaluated. The results obtained were satisfactory because all the extracts showed antioxidant activity which varied from 10 to 86%. Then the anti-radical capacity of our extracts was assessed by the DPPH method. The concentration necessary to consume 50% of DPPH varied from 2.7 to 60.5 mg/L. Aqueous and alkaline extracts were used to dye natural and artificial fibers. The coloration taken by the fibers was measured using a Datacolor D65°10 apparatus. These extracts gave a yellow color with extracts of movingui and a red color with extracts of padouk. The effect of extractives on bacteria growth showed that the extracts were bacteriostatic at the tests concentrations

Full textAbstract:
La ricostruzione dettagliata dell’architettura stratigrafica e delle facies delle successioni tardo-quaternarie sepolte al di sotto delle pianure alluvionali moderne sta assumendo un’importanza crescente come strumento per le ricostruzioni paleoambientali e paleoclimatiche e per la correlazione dei sistemi deposizionali continentali e costieri, finalizzata alla caratterizzazione geometrica di corpi sedimentari che rappresentano potenziali serbatoi. Un impulso significativo verso la caratterizzazione dell’architettura stratigrafica dei depositi tardo-quaternari del Bacino Padano è stato fornito, negli ultimi quindici anni, da un’intensa campagna di perforazioni operata dal Servizio Geologico, Sismico e dei Suoli di Regione Emilia-Romagna, nell’ambito della realizzazione della Carta geologica d’Italia in scala 1:50.000. Tuttavia, per ottenere un numero sufficiente di informazioni stratigrafiche è necessario un dataset molto esteso e le perforazioni (sondaggi a carotaggio continuo) presentano costi estremamente elevati. I limiti operativi delle descrizioni dei sondaggi a carotaggio continuo possono essere superati utilizzando metodi indiretti che si basano sullo sfruttamento delle proprietà geotecniche dei depositi tardo-quaternari. In questo lavoro di tesi l’analisi delle caratteristiche geotecniche delle prove CPTU è stata sfruttata per caratterizzare le associazioni di facies della Pianura Padana centrale. Una dettagliata analisi dei log stratigrafici e, in particolare, delle curve di resistenza delle prove CPTU inserite nelle sezioni, la costruzione di sezioni stratigrafiche e un meticoloso lavoro di correlazione basato su 19 datazioni radiometriche, ha rivelato una serie di paleosuoli (inceptisuoli) impilati nei 50-60 m più superficiali della successione tardo-quaternaria della Pianura Padana centrale; questi paleosuoli rappresentano l’unico marker stratigrafico all’interno di una successione costituita prevalentemente da depositi argillosi uniformi. L’analisi delle caratteristiche geotecniche di alcuni paleosuoli e dei loro rapporti con la channel belt del Fiume Po risulta fondamentale per comprendere l’evoluzione recente del Bacino Padano e le caratteristiche geometriche dei corpi sedimentari finalizzata allo sfruttamento di potenziali risorse fluide sotterranee.

La thèse de doctorat examine certains aspects des textes français de matière religieuse et agiographique produits ou copiés dans l’Italie du nord entre le XIIe et le XVe siècles. Elle procède à travers un pointillisme critique, en parlant non seulement de manuscrits, mais aussi d’épigraphes, de mosaïques, de bas-reliefs, de relations de voyage, de chroniques, de lettres d’accompagnement, de textes brefs tels que des vies de saints et des prières mises en circulation séparément, de livres démembrés. Une Remembrance de Marin Sanudo le Vieux, une traduction tirée de l’œuvre du dominicain Jean de Mailly, un fragment du Joseph d’Arimathie en prose sont parmi les documents inédits publiés. La thèse est complétée par une chronologie et par un dossier iconographique qui présente trente-six documents<br>This PhD thesis examines some aspects of French religious and hagiographic texts that were produced or copied in Northern Italy between the eleventh and the fifteenth century. This work is an exhaustive analysis of a large set of documents, including manuscripts, epigraphs, mosaics, bas-reliefs, accounts of journeys, chronicles, covering letters, short reports on saints’ lives, or brief prayers diffused separately, as well as of parts of dismembered books. A Remembrance by Marin Sanudo the Elder, a translation extracted from a work by the Dominican chronicler Jean de Mailly, and a fragment from the Joseph d’Arimathie en prose are among the original papers never published before. The thesis is completed by a chronology and an iconographic study of thirty-six documents

Mulyani, Rini. "Extended framework for earthquake and tsunami risk assessment : Padang City : a case study." Thesis, University of Sheffield, 2013. http://etheses.whiterose.ac.uk/4556/.
Full textAbstract:
The Great Sumatra earthquake and resulting devastating tsunami in 2004 have highlighted the significance of earthquake risk assessment that can effectively include all main associated hazards, such as tsunami. An integrated quantification of earthquake and tsunami risk is challenging due to mathematical and computational issues as well as limited data, and as such it has not been done before in developing countries. In addition, the conventional Probabilistic Seismic Hazard Assessment (PSHA) generally assumes a Poissonian earthquake model with a stationary rate of hazard. However, hazard rates increase with elapsed time since last large earthquake, or when a seismic gap is present along a fault, and thus, a time dependent (non-Poissonian) PSHA model is generally more suitable. The Earthquake Risk Assessment (ERA) Framework developed at the University of Sheffield is extended in this study to account for tsunami and to include a time dependent hazard assessment. The ERA Framework is based on a stochastic approach that utilizes readily available seismological information. Hence, it is suitable for use in developing countries. The extended framework is used to carry out earthquake and tsunami hazard assessments for Sumatra. This study finds that a maximum PGA of 0.65g on bedrock is expected in the area, a value comparable with that found in other recent studies, but higher than the Indonesian seismic code SNI 03-1726-2002 (the code uses a value of 0.3g). In addition, the time dependent model of this study captured the increased rate of hazard in the middle segment of the Sumatra Subduction Zone, which is consistent with the location of the seismic gap. Currently, the seismicity of this region has increased about 2 times above that of the long term rates. An average tsunami height of 20.7 m is estimated for Padang city at 10% probability of exceedance in 50 years. This study estimates that total earthquake and tsunami risks for buildings in Padang are approximately £54.5 million and £30.8 million per annum, respectively. The annual fatality risk due to tsunamis is much higher than that due to earthquakes, which is approximately 2000 and 8 fatalities, respectively. Total earthquake premiums for the existing building stock of Padang are estimated to be 36.4‰, 16.6‰, 8.1‰ and 3.1‰ for UBM, CBM, RCI and steel structures, respectively. For tsunami hazard, the recommended premium rates are 11.7‰, 9.9‰ and 7‰ for UBM, CBM, RCI/steel structures, respectively. For seismically designed structures, the premium rates decrease about 80% and 25% for earthquake and tsunami hazards, respectively. Earthquake insurance rates applied by insurance companies in Indonesia are comparable with those estimated for seismically designed structures (1.9‰ for RC/steel buildings and 4.7‰ for other buildings). Mitigation strategies to minimize the risks are proposed including the enforcement of seismic design provisions for all buildings in Padang, nationwide obligatory seismic insurance for buildings, tsunami vertical evacuations shelters and tsunami energy dissipation efforts (e.g. offshore barriers, coastal vegetation). At least 17 points of tsunami evacuations refuges are proposed for Padang city, to increase the survival probability of the residents in the area.

Full textAbstract:
La realizzazione di cinque sezioni stratigrafiche nel territorio padano, orientate SSW-NNE e con profondità di circa 200 m, ha consentito lo studio della successione sedimentaria tardo-quaternaria della Pianura Padana centrale e dei suoi acquiferi, in particolare quelli più superficiali. La ricostruzione, ottenuta utilizzando le stratigrafie di pozzi per acqua fornite dall’archivio del Servizio Geologico, Sismico e dei Suoli di Regione Emilia-romagna, ha permesso di evidenziare una ciclicità deposizionale del 4° ordine, controllata da fattori glacio-eustatici. Grazie al riconoscimento di cicli trasgressivo-regressivi sono stati individuati cinque subsintemi corrispondenti ad altrettanti complessi acquiferi.
La ricostruzione di pattern ciclici all’interno del Bacino Padano ha permesso la ricostruzione geometrica dei corpi sedimentari di channel-belt del Fiume Po, spessi corpi sabbiosi confinati da materiale impermeabile in cui sono contenute le falde acquifere. Alle informazioni stratigrafiche e litologiche si è unito lo studio delle caratteristiche idrochimiche ed isotopiche degli acquiferi, in modo tale da ottenere una chiave di lettura integrata dei depositi padani.
Basandosi sulle diverse caratteristiche isotopiche delle acque è possibile risalire alla provenienza delle acque negli acquiferi. In questo modo si ottengono informazioni circa le modalità di ricarica dell'acquifero e la sorgente della ricarica. Un'applicazione secondaria di questo metodo è la verifica della vulnerabilità degli acquiferi padani. Lo studio delle facies idrochimiche è stato sovrapposto a quello dei valori isotopici delle acque, con l'obiettivo di definire una correlazione tra i due fattori chimici all’interno degli acquiferi. L'obiettivo di questa correlazione è quello di identificare la provenienza di un'acqua di ricarica senza la necessità di dati di natura isotopica.

Cette thèse résume une démarche intégrée visant à évaluer l’exposition humaine et ses variations spatio-temporelles en cas de tsunami dans une zone urbaine littorale en Indonésie, ainsi que la capacité d’évacuation vers des refuges. Ce travail de recherche systématise des méthodes permettant d’estimer la quantité de population présente heure par heure durant n’importe quel jour de la semaine et de l’année, à une échelle très fine, dans une zone urbaine. Il se fonde pour cela sur une hypothèse de rythme de vie contrôlant les activités et donc la distribution de la population. L’heure d’arrivée d’un tsunami étant imprévisible, ces informations sont très importantes pour améliorer les programmes de réduction du risque. Cette démarche permet ainsi de dégager des scénarios types de distribution de la population, utilisés pour ensuite évaluer la capacité d’évacuation de ces populations. Le modèle de simulation dynamique issu de cette recherche permet de mesurer l’accessibilité des zones selon certains scénarios, et de proposer des améliorations pour une meilleure préparation de la protection des civils<br>This dissertation summarizes an integrated approach whose aim is to assess the human exposure and its spatial and temporal variations in the event of a tsunami in a costal urban zone of Indonesia, as well as the capacity to join evacuation shelters for populations under threat. This research systematizes methods to estimate the amount of people present hour by hour during any day of the week and the year, at a very fine scale, in an urban area. It uses a hypothesis about a common rhythm of life which controls the activities and therefore the distribution of the Padang inhabitants. Considering that time of a tsunami occurrence is impossible to estimate, this information is very important to improve risk reduction programs. This approach allows in particular identifying various types of scenarios for the distribution of the population that can then be used to evaluate the evacuation capacity of these populations. A dynamic simulation model resulting from this research allows for the measurement of the accessibility of shelters following these scenarios. The analysis of the results suggests improvements for a better preparation on the part of authorities to protect civilians

Full textAbstract:
The thesis which follows is concerned with developing a new approach to political theory as it is practiced in the Anglo-American tradition. This tradition has been characterized by certain assumptions regarding the foundations of political theory, the most important of which has been the primacy accorded to the individual and to the political rights which develop to protect this primacy. Recent political experience in the West presents a strong challenge to the individualist stance. The rise of political interest groups, which serves as the empirical starting point for this thesis, has brought out the shortcomings of our democratic theory into the open. Various critiques, from a feminist, Marxian, ecological or other point of view, have shown how the individualism of our tradition has reached certain limits. These also show the need for a new development in political thought. The thesis is divided into two parts. The first part is diagnostic in nature: it seeks to isolate a specific question to be asked, a heuristic notion of representation that can serve as a template for further inquiry. This first part is made up of two chapters. The first chapter looks at representation from the point of view of the representative. The second chapter turns to the interests of the represented. In the second part, which is made up of three chapters, the work of Marsilius of Padua is studied to try to glean a possible solution to the heuristic notion developed earlier. Marsilius' understanding of politics is founded on a corporate notion of the individual, which is why his work is of interest. The chapters develop, in order, Marsilius' historical context, some key notions in his text, and finally some conclusions for our own theoretical enterprise. (Abstract shortened by UMI.)

The aim is to determine a methodology which asks to the analyst a deep knowledge of the software used in the pieces, linked with his impersonal, as much as it's possible, listening. The six pieces use MUSIC software for sound synthesis. This type of programs, common within the musical research in Padova and Paris, has been chosen to permit a comparison of the two Centers' works and to trace a method to evaluate different approaches to computer music

La historia de la conciencia del cuerpo en la arquitectura y las artes, desde los asclepeiones
griegos hasta los hospitales modernos, fue consolidada por la investigación anatómica y
desarrollada con mayor precisión en arquitecturas destinadas al saber del cuerpo: los teatros
anatómicos. Estos espacios fueron organizados entorno a la disección anatómica,
centralizados en el cadáver, y oscilaron entre el ocultamiento y la pública escenificación de la
performance anatómica, cobijando desde el hombre renacentista hasta el higienista hombre
ilustrado. Esas arquitecturas reflejaban las ambiciones de los anatomistas o cirujanos que las
gestaron, pero además reflejan el espíritu del tiempo en cuanto a su diseño. Mediante tres
obras de arquitectura situadas entre los siglos XVI y XVIII, se puede comprender el medio
donde se desarrollaron estas escenas de producción en torno a la conciencia del cuerpo y de
su espacio: en Padua, con el anfiteatro gestionado por Girolamo Fabrici d’Acquapendente y
atribuido a Dario Varotari; en Barcelona, ejecutado por Pere Virgili y Ventura Rodríguez; y en
París, erguido gracias a Germain Pichault de La Martinière y Jacques Gondoin<br>The history of body consciousness in the architecture and the arts, since the Greek
asclepieion to modern hospitals, was strengthened by the anatomical research and developed
more accurately in the architecture for the knowledge of the body: the anatomical theaters.
These spaces were organized around anatomical dissection, based at the corpse, and ranged
between concealment and public staging of the performance anatomy, sheltering from the
renaissance man to the hygienist illustrated man. These architectures for theaters reflected
the ambitions of the anatomists or surgeons who originated them, but also reflect the spirit of
the times in terms of design. By three works of architecture located between the sixteenth and
eighteenth century, is possible to understand the context in which these scenes were
developed around the production of body consciousness and its space: Padua, with the
amphitheater negotiated by Girolamo Fabrici d’Acquapendente and attributed to Dario
Varotari; Barcelona, executed by Pere Virgili and Ventura Rodriguez, and Paris, build by
Germain Pichault de La Martinière and Jacques Gondoin.

No presente trabalho, é proposto um método indireto para a determinação de cromo(VI) na presença de cromo(III). O método é baseado na reação de redução do cromo(VI) por ferro(II) e reação de complexação do ferro(II) que não reagiu com o reagente 2-(5-bromo-2-piridilazo)-5-dietilaminofenol (Br-PADAP). O ferro(II) reage com Br-PADAP, formando um complexo estável que absorve a 560 e 748 nm. Os seguintes parâmetros foram estudados: efeito do volume da solução de referência na reação de oxidação, efeito de pH na reação de oxidação, quantidade de ferro(II), efeito de pH na reação de complexação, quantidade de Br-PADAP, quantidade de EDTA, sensibilidade de calibração, sensibilidade analítica, efeito de outros íons e precisão. Os resultados demonstraram que cromo(VI) pode ser determinado na presença de cromo(III), com absortividade molar aparente de 7,3 x 104 l. mol-1. cm-1 a 748 nm. O uso de EDTA permite um procedimento com boa seletividade. Os resultados revelaram que 275,0 g de cromo(III) não interfere durante a determinação de 5,0 g de cromo(VI).

Este método foi usado para determinação de cromo(VI) em amostras de água coletadas no efluente do rio Catu na cidade de Pojuca, na Bahia.<br>The speciation of chromium is very important because the chromium(VI) is known to be toxic to humans, while that the chromium(III) is essential at trace levels to maintain normal glucose to animals and man. In the present work a indirect method for chromium(VI) determination in the presence of chromium(III) is proposed. It is based on the oxidation reaction of iron(II) by chromium(VI) and complexation reaction of unreacted iron(II) with the spectrophotometric reagent 2-(5-bromo-2-piridilazo)-5-dietilaminofenol (Br-PADAP). The iron(II) reacts with Br-PADAP, forming a stable complex which absorbs at 560 and 748 nm. The sequentes parameters were studied: effect of reference solution volume on the oxidation reaction, effect of pH of reference solution on the oxidation reaction, amount of iron(II), effect of pH on the complexation reaction, amount of Br-PADAP, amount of EDTA, calibration sensitivity, analytical sensitivity, effect of other ions and precision. The results demonstrated that chromium(VI) can be determinated in the presence of chromium(III), with apparent molar absorptivity of 7,3 . 104 l. mol-1. cm-1 at 748 nm. The use of EDTA as masking agent allowed a procedure with great selectivity. The results revealed that 275.0g of chromium(III) do not interfere during the determination of 5.0 g of chromium(VI). A good precision (R.S.D. 2%) was obtained. This method was used for chromium(VI) determination in water samples in the effluent of the Catu river, in the Pojuca city, Bahia.

Full textAbstract:
Le temps de la contre-réforme ou l’Age baroque nous offre le cadre essentiel où l'on doit inscrire le sujet de notre recherche : Vanini (1585-1619) et ses écrits; ce serait la meilleure façon de la mettre à l'abri des interprétations tendancieuses ou anachroniques, si fréquentes dans les approches faites jusqu'à une époque récente. Ce temps était fortement conditionné par une "logique de guerre" et l'imaginaire intensément travaillé par des métaphores récurrentes nourries de connotations sceptiques, qui tendaient à voir la vie comme un "songe" et le monde comme un "théâtre". Les gestes, les écrits -somme toute les actions du philosophe-, une fois resitués dans ce contexte, présentent, pour l'histoire de la pensée, l'intérêt d'une réponse originale ; même si Vanini se sert d'éléments d'autres courants et de doctrines présentes dans la philosophie de la renaissance tardive, et qu'il construit cette réponse sur les débris d'un savoir en crise (l'aristotélisme) cautionnant, dans sa version la plus orthodoxe, la violence idéologie de la contre-réforme, principale cible de sa critique. Son côté radical et sa valeur d'anticipation expliqueraient le composant polémique qui l'a toujours accompagné, mais aussi sa capacité d'agir, de par sa particulière insertion dans le courant libertin, comme un catalyseur ou une référence difficile à oublier quand il s'agit de repenser certains sujets importants lies au surgissement, à la consolidation d'une certaine mentalité moderne ainsi qu'à ses contradictions inhérentes : conception des fondements et fonction du savoir, place que l'on accorde à la nature et à l'homme dans la nature, relation philosophie-religion, philosophie-pouvoir, façon d'envisager les notions métaphysiques et l'horizon de la transcendance, possibles bases d'une éthique ne s'appuyant plus sur un fondement religieux<br>The topic of our research is G. C. Vanini's life and works (1585-1619). Until recently, these have been partially or anachronistically interpreted. That is why we have decided to place them in their proper context, within the age of counter-reformation, or the age of barocco. This was a time strongly conditioned by a "logic of war", a time when imagination was deeply concerned by recurrent metaphors with sceptic connotations that tended to contemplate life as a "dream" and the world as a "theatre". Every deed and writing of this philosopher can be analyzed as an original answer in the history of thought, once they are replaced in their right context, Vanini uses elements from other schools and doctrines from the late renaissance philosophy and builds upon the ruins of a thought in crisis (Aristotelian tradition) that -in its most orthodox version- legitimates the violent ideology of counter-reformation, which is Vanini's main target. His radicalism, as well as his ability for anticipation would explain the controversy that has always accompanied him, under the contradictory labels of "hero" or "damned". It would explain as well his capacity for acting as a catalyst -within the libertine movement- and as a reference difficult to forget when we try to rethink some important subjects related to the origin and consolidation of a certain modern mentality and its inherent contradictions: the conception of the basis and functions of knowledge, the place we assign to nature -and to man in nature-, the relationships between philosophy and religion or philosophy and power, the way to consider the metaphysical concepts or the horizon of transcendence, and the possible basis of an ethical theory that isn't based on religion any longer

Full textAbstract:
This thesis analyses the nation-building work that the Indian Army undertook during the military administration of Malaya, 1945-6. This was a two-part process, taking in military-led relief work and a political reform scheme. Historians have conducted little work on the Indian Army’s role in the British return to empire in Malaya, thus the army’s crucial and nuanced role has been overlooked. This limits the understanding of the army’s institutional development and role in Malayan nation-building between 1945-6. This thesis redresses this. It argues that the military administration of Malaya encapsulated the culmination of wartime changes to the role of the Indian Army fighting soldier. Whereas before the war the Indian Army found it expedient to keep its soldiers isolated from current affairs, British experience during the Second World War instead suggested that soldiers educated in current affairs could be very effective. Concurrently, British military leaders began to think on the role of the Indian Army and its men after the war. They concluded that the Indian Army’s soldiers could become catalysts of national political and social development, and initially identified this as a role for the army in post-war India. Furthermore, it was felt that the Indian Army could contribute both to the Commonwealth and United Nations ideals. The return to Malaya encapsulated these changes to the conception of the Indian Army soldier and was a practical expression and measure of these. The soldiers became agents of political change, imperial re-entrenchment and administration – which this thesis terms ‘soldier-administrators’. The Indian Army, it is argued, was deployed consciously as a nation-building force, using the new thinking on the role of Indian Army soldiers. In so doing, the Indian Army partook in targeted schemes for military relief, political reform and nation-building to try to build the new Malayan nation.

In questo elaborato sono state analizzate le distribuzioni dimensionali degli aerosol misurate nella stazione
meteorologica di San Pietro Capofiume relative al periodo compreso tra marzo 2002 e ottobre 2013,
focalizzando l’attenzione sugli eventi di nucleazione, la crescita delle nuove particelle e la correlazione del
fenomeno con i parametri meteorologici del vento, della pioggia, della temperatura e con i dati relativi alla
radiazione solare. Le osservazioni del particolato sono state effettuate con un sistema DMPS (Differential
Mobility Particle Sizer), che rileva particelle di diametro compreso tra 3 e 660 nm.
Si è notato che la formazione delle particelle di diametro compreso tra 3 e 10 nm e 10 e 20 nm dipende
fortemente dalla radiazione solare: ad un massimo della radiazione, corrisponde mediamente un aumento
della concentrazione delle particelle.
Dal confronto delle temperature medie mensili (massime e minime) con la concentrazione delle particelle di
diametro compreso tra 100 e 300 nm e 300 e 700 nm, si è visto che all’aumento delle temperature
corrisponde una diminuzione della concentrazione delle particelle. Per quanto riguarda il confronto della concentrazione delle particelle con la
direzione e la velocità del vento, non si è notata alcuna relazione. L’unico particolare che si è notato è che
durante la primavera e l’estate si nota un aumento della concentrazione delle particelle con diametro
compreso tra 3 e 10 nm associate a venti provenienti dai quadranti orientali. Poiché le precipitazioni
rimuovono gli aerosol dall’atmosfera causando repentini cali nella loro concentrazione, per verificare che i
risultati ottenuti non fossero alterati da questi eventi, abbiamo ripetuto tutte le analisi di correlazione con le
variabili meteorologiche escludendo i giorni con precipitazione superiore o uguale ad 1 mm. Tuttavia i
risultati sono rimasti invariati.

Full textAbstract:
À cheval sur les Alpes occidentales, les Etats de Piémont-Savoie occupent une place majeure sur l'échiquier européen tout au long de l'époque moderne. Or, rares sont les historiens français, italiens et anglophones à se pencher sur cette monarchie en dépit du récent renouveau historiographique insufflé par les Sabaudian Studies à l'initiative de l'historien américain Matthew Vester. Aucune étude approfondie sur la construction territoriale de cet Etat secondaire (puissance moyenne) n'a été menée jusqu'à présent : les recherches françaises se restreignent le plus souvent à des études locales centrées sur les questions économiques, sociales et religieuses de la « région Savoie », tandis que les historiens italiens ont produit depuis la seconde moitié du XIXe siècle de nombreux travaux cantonnés à l'histoire politique du Piémont. Quant aux Anglo-saxons, ils ont travaillé sur de trop courtes périodes pour saisir l’ensemble des mécanismes du processus d'étatisation du Piémont-Savoie. Un renouveau historiographique est nécessaire sur cette monarchie composite fragmentée par les montagnes entre les pays de « l’au-delà » (versant français) et ceux de l’ « en-deçà » (versant italien). Si cette thèse se focalise sur le Piémont, cœur politique de cette monarchie depuis 1563, la Savoie et le comté de Nice seront aussi évoqués pour surmonter l'impasse dans laquelle se trouve la plupart des études « régionales » menées jusqu'à présent. Cette étude vise à approfondir nos connaissances sur cet Etat secondaire qui a façonné les versants français et italien des Alpes. Elle amène aussi à envisager autrement l'histoire de l'Europe à travers une histoire politique et diplomatique renouvelée d’une dynastie européenne : celle de la maison de Savoie, de sa restauration en 1559 (ses États sont occupés dans le cadre des guerres d’Italie depuis 1536) à l’annexion de Nice et de la Savoie par la France révolutionnaire à l’automne-hiver 1792-1793. Il convient de partir du postulat suivant : la construction du Piémont-Savoie dans l'Europe d'entre-deux disputée entre la France et les Habsbourg est conditionnée par la politique d'une dynastie souveraine au succès parfois mitigé, ainsi que par le jeu des grandes puissances soucieux de préserver l’équilibre européen. Trois axes seront à privilégier. Le premier est l’ambitieuse politique territoriale de la maison de Savoie qui bascule d'un versant à l'autre, puis consolide et étend son Piémont peu à peu élevé au statut de puissance italienne. Ensuite, la diplomatie de cette dynastie en quête d’indépendance vise s’affirmer face à ses voisins hégémoniques (France et Empire). Enfin, il convient de s’intéresser au(x) rôle(s) que les grandes puissances (France, Empire, Espagne et Angleterre) attribuent à cet Etat d’abord considéré comme un « territoire-tampon » empêchant tout contact direct entre la France et le Milanais espagnol, puis comme un « État-barrière » empêchant la France d’entrer en Italie et un « Etat-équilibre » contrebalançant la puissance autrichienne à la tête de la moitié de la péninsule. Cette réflexion sera prolongée par un court épilogue sur le sort de cette monarchie progressivement annexée par la France révolutionnaire jusqu’à disparaitre une seconde fois en 1802. S’achève ainsi une histoire possible du Piémont-Savoie commencée deux siècles et demi plus tôt

Previous issue date: 2006<br>Resumo: Esta dissertação discute como a reforma universitária italiana, implantada através do Decreto Ministerial n°509/99, influenciou a formação em psicologia, focalizando principalmente a psicologia educacional. Certa debilidade no ensino superior italiano e acordos entre os países membros da Comunidade Européia, ensejando a formação de uma Área Européia de Educação Superior, serviram como justificativa para a reforma. Um dos principais objetivos declarados foi o reconhecimento profissional entre os países e, para compatibilizar os sistemas de cada país, foi implantado um modelo baseado em dois ciclos e créditos formativos, com preocupações profissionalizantes desde o ciclo inicial. O processo de reestruturação didática que aconteceu na Universidade de Pádua durante a pesquisa foi estudado num enfoque contextual; tendo sido optado pelo estudo de caso como alternativa metodológica. Foram entrevistados o Presidente da Faculdade de Psicologia, o Assessor da Presidência para Assuntos Discentes, o Diretor do Departamento de Desenvolvimento e Socialização e quatro professoras deste departamento. Além das entrevistas, currículos do ciclo inicial e reportagens publicadas em jornais italianos foram usados para auxiliar a reflexão. De maneira geral, o modelo implantado não foi bem recebido pelos estudantes, pelos docentes e nem por outros segmentos sociais, tendo recebido várias críticas, sendo a falta de uma formação geral mais ampla uma das principais<br>Abstract: This dissertation is about the Italian reform of universities, implemented by Ministerial Law n°509/99, concerned with psychology graduation courses and educational psychology in special. A supposedly weak Italian Higher Education and agreements for building a European Area of Higher Education were used to justify the reform. A model with two cycles and credits for a professional formation were proposed to overlap the educational systems from each nation. A case study was used to understand the new didactic structure in Padova University and its social context. News, curriculum and interviews with the President of the Faculty of Psychology, the President-Assessor for Student Matters, the Director and four teachers from Development and Socialization Department served as data information. Meanwhile, students, teachers, and another social segments didn¿t approve the implemented formation¿s model.

Previous issue date: 2008<br>Resumo: O objeto de estudo da dissertação é a obra Aparição do Menino Jesus a Santo Antônio de Pádua, 1627-1630, pintada pelo espanhol Francisco de Zurbarán (1598-1664) e conservada pelo Museu de Arte de São Paulo 'Assis Chateaubriand¿. A tela mostra um santo no sublime momento de sua visão mística. As características da fisionomia da figura geraram opiniões contrárias quanto a sua identidade, estabelecendo uma dúvida entre a representação dos dois mais populares santos franciscanos: Santo Antônio de Pádua e São Francisco de Assis. A dissertação apresenta uma análise iconográfica comparativa da obra em questão com outros quadros de mesma temática pintados por Zurbarán, com o objetivo de esclarecer qual é o santo representado na tela. A iconografia de ambos os santos apresenta algumas variações no século XVII que visaram adequá-las à uma nova iconografia religiosa que demonstrava uma clara preferência para a representação de santos em momentos de êxtase. O texto comenta alguns aspectos relativos a essas mudanças, dando especial atenção à evolução observada nas representações da aparição do Menino Jesus a Santo Antônio de Pádua, do final do XVI até o fim do século XVII<br>Abstract: The object of this study is the painting Aparição do Menino Jesus a Santo Antônio de Pádua, 1627-1630, executed by the Spanish painter Francisco de Zurbarán (1598- 1664), and kept at the Museu de Arte de São Paulo 'Assis Chateaubriand¿. This canvas depicts a saint at the sublime moment of his mythic vision. The character¿s physiognomy has given rise to opposite opinions about his identity, which therefore generated a doubt about the representation of the two most popular Franciscan priests: Saint Anthony of Padua and Saint Francis of Assis. This thesis presents a comparative iconographical analysis of this painting and of other paintings of the same theme by Zurbarán in order to find out which saint has been depicted. The iconography of both saints presented some variations throughout the seventeenth century, which aimed at adjusting it to a new iconography favoring the depiction of saints in moments of trance. This text discusses some aspects of this change, with special attention to the evolution of the representations of the apparition of Infant Jesus to Saint Anthony of Padua, from the end of the sixteenth century until the end of the seventeenth century<br>Mestrado<br>Historia da Arte<br>Mestre em História
