Full textTiivistelmä Tärkkelys on yksi yleisimmistä luonnossa esiintyvistä polysakkarideista. Sitä hyödynnetään useilla eri teollisuuden aloilla. Monimutkaisen rakenteensa vuoksi tärkkelys on liukenematon useimpiin orgaanisiin liuottimiin ja veteen, minkä vuoksi sitä täytyy modifioida ennen käyttöä. Tässä väitöstutkimuksessa tärkkelyksen modifioinnissa käytettiin ionisia nesteitä reaktioväliaineena. Tutkimuksen alussa eri tärkkelyslajeja depolymeroitiin 1-allyyli-3-metyyli-imidatsoliumkloridissa ([AMIM]Cl) katalyyttinä p-TsOH. Mikroaaltoaktivointia ja haudekuumennusta käytettiin vaihtoehtoisina lämmitysmenetelminä. Reaktion edistymistä ja tuotteiden muodostumista tutkittiin HPLC-ELSD -menetelmällä. Eri tärkkelyslajit depolymeroituivat samankaltaisesti vesiliukoisiksi, lyhytketjuisiksi tärkkelysoligomeereiksi. Mikroaaltoaktivointi lyhensi reaktioaikaa haudekuumennukseen verrattuna. Tutkimuksen seuraavassa vaiheessa tutkittiin ohratärkkelyksen liukoisuutta ja depolymeroitumista eri ionisissa nesteissä. Tulosten perusteella ionisen nesteen sekä anioni- että kationiosa vaikuttivat tärkkelyksen liukenemiseen. Depolymeroidun ohratärkkelyksen modifiointitutkimuksia jatkettiin [AMIM]Cl:ssa kationisoinnilla. Lämmitysmenetelmänä käytettiin mikroaaltoaktivointia. Tuotteet tutkittiin käyttäen alkuaineanalyysiä sekä HPLC-ELSD- että 1H NMR-tekniikoita. Kationisoitujen tuotteiden substituutioaste (DS) vaihteli reaktio-olosuhteista riippuen välillä 0.2–0.5. Saatuja tuotteita tutkittiin raskasmetalli-ionien sitomisessa vesiliuoksesta. Havaittiin, että kohtalaisesti substituoitu (DS 0.4) modifioitu tärkkelys sitoi Cu(II)-, Fe(III)- ja Zn(II)-ioneja vesiliuoksesta. Tutkimuksen loppuosassa tutkittiin perunan kuorijätettä vaihtoehtoisena tärkkelyslähteenä kationisoidun tärkkelyksen valmistamisessa. Kuorijäte esikäsiteltiin kuumentamalla se emäksisessä etanoliliuoksessa, minkä jälkeen sille suoritettiin kationisointi vesiliuoksessa. Kationisten tuotteiden substituutioasteet vaihtelivat välillä 0–0.35. Tuotteiden soveltuvuutta Cu(II)-ionien sitomiseen vesiliuoksesta tutkittiin ICP-OES -menetelmän avulla. Alustavien tulosten mukaan kationisoitu jätetärkkelys sitoi kupari-ioneja vedestä, kun tärkkelyksen ja kuparin moolisuhde oli 3:1

Full textThe evolution of tropical carbonate platforms depends on complex interacting factors influencing the sedimentation, such as tectonism, climate, eustacy, hydrodynamism etc… Due to this complexity, it has been of scientific interest for decades. Carbonate platforms are not only prone to accumulate sediments, but also represent prolific carbonates “factories” producing more than they can store on their tops. Excess sediments are shed basinward. Platform-to-basin transitions exemplify interactions between in-situ carbonate production, transfer and sedimentary accumulations resulting from re-sedimentation. In south-west Albania, the Upper Cretaceous carbonate series are made up of platform and basinal deposits. Sedimentary successions are presently integrated in the Dinarides-Hellenides fold-and thrust belt that originate from a Plio-Holocene phase of the Alpine Orogeny. The paleogeographic setting during the Late Cretaceous reveals a juxtaposition of mega-platforms and adjacent basins, partly filled with sediments derived from the shelf edge. Our scientific investigations focused on five study areas. Macro- and microfacies descriptions are provided for eight platform and basin successions. Sedimentary units are defined and mapped on each study area, supporting the stratigraphic reconstruction of the system. Dating is based on biostratigraphy and supported by strontium-isotope data. Regarding platform deposits, facies descriptions are seconded by complementary methods of petrography (cathodoluminescence, epifluorescence, scanning electron microscopy), petrophysics (mercury intrusion porosimetry), and geochemistry (stable carbon and oxygen isotopes), aiming to precise the sedimentation dynamics and reservoir properties of the succession. The sedimentation conditions are specified: i) within the platform, ten specific facies are identified, precising the depositional setting that comprise supra-, inter- and subtidal environments. These facies are integrated in distinctive stacking patterns (small-scale-sequences) pointing to a cyclic sedimentary dynamic controlled by high-frequency and low-amplitude sea level changes; ii) the basinal deposits comprise fourteen facies classified according to the dominant grain-support mechanism. Spatial distribution of the deposits allowed identifying the provenance and preferential sources of calciclatic sediments. The tectono-sedimentary evolution of the platform-to-basin system during the Late Cretaceous can be subdivided into two sequences: i) from the Cenomanian to the Turonian, the platform sedimentation is characterized by a substantial aggradation (700 meters) of intertidal small-scale sequences. No significant transfer was evidenced in the adjacent Ionian Basin, pointing to stable conditions in a subsiding context; ii) the Coniacian-Santonian interval evidences the establishment of a rudist platform massively shedding sediments basinward during the Campanian. A clear progradation of gravity-flow deposits is attested during this period. During the Upper Campanian and Maastrichtian, this transfer is accentuated by the setting of tectonically-triggered slumps resulting from the dismantling of the platform edge

Full textIn the Eastern Mediterranean, the South-Tethys paleo-margin experienced poly-phased rifting episodes during Paleozoic and Mesozoic times. This margin has been subsequently inverted by discontinuous events occurring since the Late Cretaceous as a consequence of the Africa-Eurasia convergence.The Cyrenaica margin (northeast Libya) has recorded these extensional and compressional events. It thus gives the opportunity to analyse these inversion and their possible causal links with events occurring along the plate boundary (i.e. within the Hellenic subduction).The adjacent Sirt Basin, follows an oblique direction, did not suffer the same deformation as Cyrenaica and has recorded a continuous subsidence since the Mesozoic.Offshore seismic data combined with well correlations have permitted us to investigate and discuss the interactions between Cyrenaica, Sirt Basin and the deeper domains (i.e. Ionian Basin).We were able to document the different rift episodes, better constrain the compressional events on Cyrenaica, observe characteristics of the architecture of the Sirt Basin and clarify part of its evolution.Finally we integrate this part of the margin, in the regional geodynamic frame of the East Mediterranean branch of the Neo-Tethys by discussing the timing and mechanism which led to its opening

Full textIn the Ionian Sea (central Mediterranean) the slow convergence between Africa and Eurasia results in the formation of a narrow subduction zone. The nature of the crust of the subducting plate remains debated and could represent the last remnants of the Neo-Tethys ocean. The origin of the Ionian basin is also under discussion, especially concerning the rifting mechanisms as the Malta Escarpment could represent a remnant of this opening. This subduction retreats toward the south-east (motion occurring since the last 35 Ma) but is confined to the narrow Ionian basin. A major lateral slab tear fault is required to accommodate the slab rollback.This fault is thought to propagate along the eastern Sicily margin but its precise location remains controversial.This PhD project focussed on the deep sedimentary and crustal structures of the eastern Sicily margin and the Malta Escarpment (ME). Two two-dimensional P wave velocity models were modelled by forward Modelling of wide-angle seismic data, acquired onboard the R/V Meteor during the DIONYSUS cruise in 2014.A 3D gravity model of the region was also performed to constrain the depth of the subducting slab bellow the Calabro-Peloritan backstops. The seismicity of the three structures identified in the velocity models (ME, Alfeo fault System, Ionian Fault System) permits to study their recent activity. The results image an oceanic crust within the Ionian basin as well as the deep structure of the Malta Escarpment, which presents characteristics of a transform margin. A deep and asymmetrical sedimentary basin is imaged south of the Messina strait and seems to have opened between the Calabrian and Peloritan continental terranes. In the western lobe of the Calabrian accretionary prism, the southern velocity model allows to observe the indentation of the internal clastic wedge into the external evaporitic wedge, thus showing the recent activity of this lobe. The interpretation of the velocity models suggests that the major STEP fault is located east of the Malta Escarpment, along the Alfeo Fault System

Full textHaving created the first great work of prose in Greek literature, Herodotus stands at a momentous point in the history of literary forms : he ennobles Greek prose, not only as a continuator, but also as an emulator of the poetic heritage. Indeed the author of the Peri Hupsous calls him homêrikôtatos, and the rhetor Hermogenes describes his language and style as most poetic. We shall try to understand how such a prose, long acknowledged as Kunstprosa, is imbued with features and processes that characterize the language of Homer as well as Greek poetry, in the fields of phonetics, morphology, syntax, rhythms, formulae, lexicon and composition, converging towards an aesthetics of poikilia and endowing Herodotus’ work, as regards writing techniques, with a proper poetical dimension

Full textApollodorus’ Library, probably written during the 2nd or 3rd century A. D., aims at gathering Greek legends and myths in a coherent system based upon a genealogical structure. Its author bases his work on the most authoritative sources, including prestigious 5th-century mythographers as Pherecydes and Acusilaus, whose names are the most mentioned ones in Apollodorus’ treatise, along with Hesiod’s. This work analyses the links between those two ancient mythographers and the Library. It takes a close look at every mention of their name, and compares all their fragments to Apollodorus’ text, in order to understand how and why he cites them or not ; why he draws on them or chooses other sources ; what is their real influence on his treatise. This study also offers a reflection about the links between the Library and the ancient mythographical tradition as a genre, mainly on the basis of their respective style

Full textSubmarine paleoseismology is a discipline based on the recognition and study of past earthquakes from submarine records such as turbidite deposits. This discipline was initially developed in the 1990’s in the Cascadia region (north-west coast of the USA), and was subsequently, applied to other seas, oceans and lakes. The Ionian Sea is a small, narrow and deep basin located in the central Mediterranean Sea and bounded by two accretionary wedges, the Mediterranean Ridge to the east and the Calabrian wedge to the west. Eastern Sicily and Calabria region have been repeatedly struck by destructive historical earthquakes, sometime followed by tsunamis, such as the 1693 AD earthquake in Catania (magnitude to 7.4) or the 1908 AD earthquake in Messina (magnitude to 7.1).This latter earthquake triggered a submarine landslide and turbidity currents that ruptured submarine cables. In the Ionian abyssal plain, another type of deposit is observed in seismic data, expressed as successive transparent layers. These mega-deposits, several meters in thickness, are associated with large extreme events (earthquakes, volcanic eruptions, tsunamis) and are named megaturbidites or homogenites.The research conducted during this thesis focuses on the interpretation of turbidites and mega-deposits, observed by a new data set located in the western part of the Calabrian prism and acquired during the CIRCEE cruise, in October 2013. The understanding of the sources and the origin of these deposits is essential for the interpretation of paleoseismological record in the region. The general objective is to improve our understanding of the chronology and origin of major catastrophic events that have affected the region. These new data, include piston cores, bathymetry and seismic profiles (Chirp and HR), and allow us, for first time, to revisit the interpretation of sedimentary processes and origin of mega deposits and in particular the most recent deposit named "Augias deposit" This deposit, whose thickness reaches 12 meters in Ionian abyssal plain, can be linked to the 365 AD Crete earthquake and associated tsunami. Based on the sedimentological description and different measurements that were conducted, three type facies could be identified ("megaturbidite", "homogenite" and "thick sandy turbidite") that are the expressions of different sedimentary processes.The second part of this thesis represents a paleoseismological study of the last 25 ka in Ionian Sea based on age models. The time period covered by the cores includes the end of the last glacial period, the sea level rise and the historical period. This allowed identification of deposits from the historical period whose main trigger of turbidity currents are earthquakes. On the other hand for earlier deposits, eustatic and climatic variations are shown to have a stong effect on the frequency of turbidites

Full textThis study looks at the way the ancient Greeks named their gods, through the notion of epiklesis. It focuses more precisely on the cities of Ionia and their colonies in the Propontis and the Black Sea and proposes a diachronic approach of the phenomenon, which runs from the archaic period to the late-3rd century AD. The epikleseis which are studied here were collected in epigraphical, literary and numismatic sources. Because epikleseis often raise difficulties as regards their signification, I propose to elucidate the meaning of the examples gathered here through a careful analysis of their morphology, which I consequently use as a tool for classification. I also try to put the epiklêseis back in their ritual context, by the means both of a deity- and a pantheon-focused approach. This way, I intend to show how epikleseis contribute to define the faculties of the deity and reflect interactions betweens gods inside local pantheons. Special attention is devoted to the case of Miletus pantheon and its configurations in Milesian colonies of the Pontus. The transfer from the metropolis to the colony gives valuable insights into the process through which a community adopts a deity in order to satisfy specific needs. Because it allows men to invoke, to reactivate or even to create specific facets of the gods, the epiklesis constitute a fundamental aspect of the Greek polytheism

Full textThe present work describes the implementation of ion beam analysis methods in a helium-ion-microscope for the determination of sample compositions with a focused ion beam of < 1 nm size. Imaging in the microscope is realized by scanning the focused ion beam over the sample surface while measuring the local secondary electron yield. Although this procedure leads to a high topographical contrast, neither the yield nor the energy distribution of the secondary electrons deliver reliable information on the chemical composition of the sample. For this purpose, in this work different ion beam induced secondary particles were compared with respect to their suitability for the analysis of the chemical composition in the helium-ion-microscope. In particular the information content of the particles, their analysability and their yield were evaluated. As a result, the spectrometry of backscattered particles and the mass spectrometry of sputtered secondary ions were identified as the most promising methods and regarded in detail. The investigation focused on physical limitations and detection limits of the methods as well as their implementability into a helium-ion-microscope. Therefor various concepts of spectrometers were evaluated, tested and validated in terms of their efficiency, energy resolution and practicability in the microscope. Time-of-flight spectrometry by pulsing the primary ion beam could be identified as the most suitable technique and has been successfully implemented in a helium-ion-microscope. The measurement setup, signal processing and data handling as well as comparative simulations are described in detail. Further the spectrometer was characterized explicitly in terms of time, energy and mass resolution. Spatially resolved backscattering spectra will be shown demonstrating the feasibility of performing ion beam analysis in a helium-ion-microscope for the first time on a size scale of ≤ 60 nm. By pulsing the primary ion beam the technique of secondary ion mass spectrometry becomes automatically accessible. This method provides information on the molecular composition of samples and can reach higher detection limits than those from backscattering spectrometry. For the first time, in a helium-ion-microscope measured secondary ion mass spectra and spatially resolved elemental analysis by spectrometry of secondary ions, could be demonstrated. The results of this work are published 2016 in the scientific journal Ultramicroscopy, volume 162 on pages 91 to 971. In October 2016 there will be another publication as a book chapter in „Helium Ion Microscopy“ (publisher: Springer Verlag Heidelberg)

Full textThe seismicity beneath the southern Italy and Tyrrhenian sea is mostly linked to the subduction process of the Ionian oceanic lithospere into the Tyrrhenian mantle down to about 500 km in depth. The tomographic techniques applied up to now showed a lack of detail does not allow for discriminating the smaller structures within the larger ones living open many questions on the geodynamic evolution of the area. In this thesis i presented a detailed Study of the lithospheric and intra-mantellic structures of the southern Tyrrhenian region by performing a high resolution Local Earthquake Tomographiy (LET). During this study i developed a post-processing technique called WAM (Weighted Average Model) allows the reconstruction of reliable velocity models of P and S waves. Thanks to WAM it was possible to describe the 3D shape of the Ionian slab and to suggest a new geodynamic scenario of the region based on some petrological inferences

Full textThis doctoral research is part of the activities of MAIER – Italian Archaeological Mission in Hierapolis of Phrygia (Pamukkale, Turkey) and of the investigation field on the ancient architecture in Asia Minor. Some buildings and architectural blocks of Ionic order, recently discovered, are analyzed in order to achieve a reconstruction of the monuments, not only of the plan and elevation, but also of the ancient functions and use of the buildings. The stylistic analysis is also very important, to determine the chronology of the monuments and to relate the Ionic architecture of Hierapolis with the other urban centres in Asia Minor and their architectural tradition during the Imperial period. The dissertation is focused on both the sanctuaries of Hierapolis: in the Sanctuary of Apollo, the research analyzes the Temple C, a series of Ionic capitals with decorated hypotrachelion, and a group of architectural blocks from a (Corinthian) temenos portico; in the Ploutonion, the focus is on a series of blocks from an Ionic Stoa, related to the cultic theatre.

Full textMotivated by the incomplete scientific description of the relaxation of highly charged ions in front of solid surfaces and their energy balance, this thesis describes an advanced complementary study of determining deposited fractions and re-emitted fractions of the potential energy of highly charged ions. On one side, a calorimetric measurement setup is used to determine the retained potential energy and on the other side, energy resolved electron spectroscopy is used for measuring the re-emitted energy due to secondary electron emission. In order to study the mechanism of energy retention in detail, materials with different electronic structures are investigated: Cu, n-Si, p-Si and SiO2 . In the case of calorimetry, a linear relationship between the deposited potential energy and the inner potential energy of the ions was determined. The total potential energy which stays in the solid remains almost constant at about (80 ± 10) %. Comparing the results of the Cu, n-Si and p-Si targets, no significant difference could be shown. Therefore we conclude that the difference in energy deposition between copper, n-doped Si and p-doped Si is below 10 %, which is significantly lower than using SiO2 targets. For this purpose, electron spectroscopy provides a complementary result. For Cu and Si surfaces, an almost linear increase of the re-emitted energy with increasing potential energy of the ion up to Ar7+ was also observed. The ratio of the re-emitted energy is about (10 ± 5) % of the total potential energy of the incoming ion, almost independent of the ion charge state. In contrast, an almost vanishing electron emission was observed for SiO2 and for charge states below q=7. For Ar8+ and Ar9+, the electron emission increased due to the contribution of the projectile LMM Auger electrons and the re-emitted energy amounts up to 20 % for Cu and Si and around 10 % for SiO2 .These results are in good agreement with the calorimetric values. In addition, the experimental results are compared with computer simulations based on the extended dynamical over-the-barrier model. From these calculations, the ratio of deposited potential energy that is transformed into kinetic energy before deposition due to the image charge acceleration can be maintained

Full textIn this paper, a new approach to modeling lithium ion cells is presented. In addition to a model that describes the nominal behavior of the cell, an uncertainty model is parameterized which quantifies the unavoidable difference between the nominal model and the true system behavior. For this model description a new algorithm for state of charge estimation is developed, which provides a confidence interval instead of a single unreliable value for the state of charge and avoids artifacts in the progression of the estimated state of charge over time. The properties of the state of charge estimation are demonstrated on a lithium-ion cell in an automotive application scenario.

Resumo: Neste trabalho são estudadas as propriedades fotoquímicas e morfológicas de filmes automontados compostos de um polieletrólito fraco e azocorantes em função das condições impostas nas soluções de origem, como o pH, a força iônica e tamponamento. Na automontagem, os filmes são fabricados pela deposição de camadas alternadas de dois materiais, de cargas elétricas opostas, a partir de suas soluções aquosas em um substrato de vidro. Os materiais usados foram o polieletrólito catiônico hidrocloreto de poli(alilamina) (PAH) e três azocorantes aniônicos: Vermelho do Congo (CR), Ponceau SS (PSS) e Alaranjado de Metila (MO). Foram fabricados filmes de PAH/CR, PAH/PSS e PAH/MO. Para avaliar somente o efeito do pH, foram usados três valores de pH (3, 7 e 10). Para verificar o efeito da força iônica, foram usadas soluções aquosas de cloreto de potássio em diferentes concentrações e, para verificar a influência de tampão, foram usados três sistemas tampão, um para cada valor de pH. Foram usadas as técnicas de espectroscopia UV-vis e turbidimetria para investigar as propriedades espectroscópicas das soluções, dos filmes e a solubilidade do PAH. Foi utilizada a técnica de microscopia de força atômica para verificar a morfologia do filme. Observa-se que a deposição dos corantes e do PAH no filme depende de suas densidades de carga, bem como da presença de outras espécies iônicas em solução. Tanto um aumento do pH como a presença de contra-íons, leva a uma redução da carga do PAH e causa um aumento de sua adsorção no filme, acompanhado de um aumento de rugosidade superficial. Porém, a primeira condição pode ou não diminuir as cargas dos corantes e a segunda enfraquece a atração eletrostática, reduzindo as suas deposições. As interações do par corante-PAH induzem a agregação dos corantes em solução e nos filmes. As diferenças estruturais dos corantes são igualmente importantes, pois o CR e o PSS são os que mais se depositam e apresentam diferentes comportamentos de deposição em função do pH. Verifica-se também que o PAH interage distintamente com diferentes contra-íons, o que pode ser explicado considerando-se a especificidade iônica e não o simples conceito de força iônica
Abstract: In this work, the photochemical and morphological properties of layer-by-layer self¿assembly films made of a weak polyelectrolyte and azodyes are studied in dependence of the solution¿s pH, ionic strength and buffering. In self-assembly technique, films are made from deposition of alternate layers of two compounds, which have opposite electrical charges, from their solutions onto a glass substrate. We employed the polyelectrolyte poly(allylamine) hydrochloride (PAH) which is positively ionized when in aqueous solution and the three different anionic azodyes: Congo Red (CR), Ponceau SS (PSS) and Methyl Orange (MO). Films of PAH/CR, PAH/PSS and PAH/MO were prepared. To investigate only the pH effect, three pH values were used (3, 7 and 10). To investigate the ionic strength, potassium chloride aqueous solution at different concentrations were used and to verify the buffer effect, three buffer systems were used, one for each pH. The UV-Vis Spectroscopy and Turbidimetry were employed to study the spectroscopic properties of the solutions, films and PAH solubility. The Atomic Force Microscopy was used to verify the film morphology. One observes that the dyes and PAH deposition depend on their charge densities as well the presence of other ionic species. An increase in solution¿s pH and/or the presence of counter-ions reduces PAH¿s charge increasing its adsorption on film, accompanied by a higher surface roughness. Differently, the first condition can or cannot reduce the dye¿s charge and the second weakens the electrostatic interaction, reducing dye adsorption. The pair dye-PAH interactions induces the dye aggregation both in solution and film. The structural differences between dyes are equally important, as CR and PSS are the ones that adsorb most and show different deposition behavior in function of solution¿s pH. Also, one verifies that PAH interacts distinctly with different counter-ions, a fact that can be explained considering ionic specificity and not by the simple concept of ionic strength

Full textMy PhD thesis deals with the study of the interaction between high mass stars and their surrounding medium. I am particularly interested in the way high-mass stars affect the young stars observed around them. Massive stars form ionized (HII) regions which, during their supersonic expansion, lead to the formation of a layer of gas and dust where the conditions seem to favor star formation. My work aims at understanding the properties of star formation around Galactic HII regions.Using \herschel\, data (HOBYS and Hi-GAL programs) complemented with ancillary data, I studied two Galactic \HII\, regions (RCW~79 and RCW~120) to characterize the star formation observed at their edges. To study the impact of the ionization pressure, I computed the Star Formation Rate (SFR), which suggests that RCW~79 and RCW~120 are active star-forming regions despite their low gas surface density.A new study about the G345 region is in progress. This HII region is located above the Galactic plane and is actively forming stars. With the data available, the star formation's properties is being derived such as the spatial distribution of clumps, their stellar content, the SFR and CFE. This new study offers another opportunity to better understand the photoionization feedback out of the Galactic plane. Moreover, this will complete the sample of detailed studies of \HII\, regions, allowing us to obtain a global view of the mechanisms at play and of the efficiency of star formation in these regions
