Waquet, François. "Le transfert légal de l’Empire : la lex regia entre pratique politique et modèle théorique". Electronic Thesis or Diss., Université Paris-Panthéon-Assas, 2023. http://www.theses.fr/2023ASSA0087.
Pełny tekst źródłaThe Roman political revolution of which the Twelfth Tables were the legal expression consisted in limiting the power (imperium) of magistrates through the lex, of which the people were the sole author. But the invention of Roman legalism was later and more lasting : the lex also became the source of all power in the city, making imperium a legal concept. Such legalism made it possible to confer extra-legal powers, so that the leges regiae de imperio, the repeated practice of which is attested in addition to the case of Vespasian, extended the republican form of government under the Empire. Roman jurisprudence reduced this political practice to a unitary model, the lex regia. When the Empire became Christian came into competition with Roman legalism. Nevertheless, the latter survived and continued to be used in the late Empire as a theoretical model; Justinian did not fail to take it up in his compilations, along with the Christian assertions of an imperium a Deo, but to deduce from it the unitary, indivisible, legislative and imperial character of all law. This dual heritage is reflected in the interpretations of medieval doctors, who nevertheless insisted on the legal conception of empire and, consequently, on its limits. Legal humanists, through epigraphy and history, shattered the unitary model of the lex regia by rediscovering the political practice of leges regiae de imperio, one for each prince. This contribution led to an novation of the lex regia, which went from being a royal law to becoming a law of the realm, both the source and the limit of the empire of kings claiming Roman heritage

Pełny tekst źródłaLandscape changes from the last decades of the 20th century are leading to important declines in habitat quality, giving rise to a negative impact on biodiversity at a global scale. In the Mediterranean region, afforestation and landscape homogenization arising as a consequence of rural land abandonment have been detrimental for bird species with preference for openshrub habitats. However, perturbations such as wildfires have act as opposing driving forces, maintaining the availability of open habitats and the landscape heterogeneity (habitat mosaic) favouring these bird species. The general aim of this thesis has been at identifying the ecological processes behind changes in the distribution of open-habitat bird species in response to the land-cover changes at the landscape scale. For this purpose, habitat models have been performed using data from the Atles dels Ocells Nidificants de Catalunya and cartography about environmental conditions (e.g. land-uses, topography and climate). Moreover, habitat models have been applied in the selection of priority areas for conservation of these bird species, but minimizing the likely threats of landcover changes for the species persistence. Landscape dynamics arising from rural abandonment and wildfires have been considered as the main process behind land-cover changes. The results showed that habitat loss for open-habitat bird species did not always yield a rapid decline in the occupation rate (i.e. fragmentation process), but each species may show a different response to habitat loss according to the available resources in adjacent habitats (landscape context). In this way, shrubland availability at the landscape scale may increase the potential range of the habitat used by the species, favouring the species resilience to habitat changes. However, species response may be geographically variable due to the heterogeneity in ecological conditions throughout the species range (i.e. adjacent habitat and nearby bird populations). This showed the important spatial character of the ecological processes determining species distributions at the landscape scale. Furthermore, the results confirmed the important role of fire regime for open-habitat bird species as a key disturbance process driving colonization dynamics in new available areas. Future fire events may constitute a determinant factor to improve model predictions about changes in bird species distributions. In this context, selection of priority areas for conservation was based on the current habitat suitability of the species but also on the areas showing larger probability of future maintenance of open habitats due to the role of fires. This will contribute to achieve larger efficiency of conservation measurements in the long term. Additionally, conservation of open-habitat bird species appeared to require fire management to maintain early and intermediate succession stages with a diversity of vegetation structure. This may contribute to favour landscape heterogeneity and, therefore, to preserve biodiversity in Mediterranean landscapes.

Pełny tekst źródłaObjectives: to resolve the inherent semantic conflict in the term library for patients from its origins; to develop a state of the art of the present situation to determine the degree of implementation of these libraries from the study of the hospitals in the Hospital Network of Public Use in Catalonia at the Health Area of Barcelona as a extrapolated sample for all Catalonia; and establish a framework for the development of guidelines specific to the Catalan libraries for patients. Methodology: on the basis that this service to hospitalized citizens is part of the commitments the public library has with society, a paralel study is done from the perspective of the hospitals, as it had traditionally been done, and from that of the public library. Field research results: The analysis of the data shows services of low quality, in charge of volunteers with null librarian training and without interest in the reading animation. Any library offers information related with health and the managers do not consider it necessary. In the cases in which the public library takes part the quality of the service improves substantially. Public libraries are aware of their functions, while hospital managers don't know the potential of the public library in regard to the creation and management of a library service for patients. It is produced an underuse of resources. Conclusions: the traditional library for patients has been surpassed due to the social and cultural changes and to the incorporation of the IT. It is proposed a new model of library for patients with a dual function: allow hospitalized people to continue exerting the right to the access to culture and information, as stated in the UNESCO Public Library Manifesto (1994) and facilitate the right to the information on one's own health and to a sanitary education. For the preparation of guidelines it will be necessary to take into account the potential that exists in the collaboration between public libraries, libraries for patients and libraries specialized in health science of the hospitals as well as the big advantages that suppose the IT. A library for patients should have a professional librarian, its own budget and the commitment and the involvement of both the public library and the hospital.

Pełny tekst źródłaAquests canvis es produeixen als països del Sud d'Europa d'una manera més tardana, però amb una forta intensitat i celeritat. En canvi, les noves formes convivencials que en resulten han incidit de manera feble en les estructures familiars espanyoles, catalanes i metropolitanes.
L'objectiu principal d'aquest treball és analitzar les transformacions demogràfiques i com aquestes han incidit en l'estructura i composició de les llars a la ciutat de Barcelona i la Regió Metropolitana, i un segon objectiu és el d'estudiar l'especificitat dels trets de les llars metropolitanes.
Una de les principals aportacions d'aquest treball és, precisament, el considerar dues unitats d'anàlisi: el grup i l'individu. El grup el constitueixen les unitats residencials de les quals s'analitza la seva distribució i, respecte a l'individu, s'estudien les característiques de les persones que resideixen en cadascun dels tipus de llar i la seva relació amb la persona principal.
Les fonts utilitzades per a l'elaboració de la recerca han estat el Cens de de Població de 1991 i l'Estadística de Població de 1996 a partir d'una explotació específica sol.licitada a l'Institut d'Estadística de Catalunya
Respecte a les llars, els temes que han despertat especial atenció i han estructurat la recerca són la distribució i evolució de les seves estructures. Pel que fa a les persones, s'ha estudiat el sexe, l'edat i l'estat civil de la població resident a cada unitat residencial i la relació de parentiu de la població amb la persona principal.
From the second half of the sixties, in some North and West European countries a series of demographic transformations have been produced: the fall and the delay of the fertility and marriage, the growth of breakups, the increase of births outside marriage, and the raise of longevity. These changes affect the way of forming and dissolving families as well as the households structures. The family course life diversifies itineraries. The Second Demographic Transition provides an explanatory framework.
The evolution of demographic phenomena is produced later in the South European countries although with a strong intensity and celerity. However, the new resulting lifestyles have a little effect upon the Spanish, Catalan and metropolitan households structures.
The first goal of this thesis consist in analyze the demographic changes and their effect to composition and structure of households in the city of Barcelona and the Metropolitan Region; the second goal is to study the specificity of the metropolitan family features.
For this research, the 1991 Census of Population and the 1996 Statistics of Population have been used as a sources, starting from a specific exploitation requested to the Institute of Statistics of Catalonia.

Pełny tekst źródłaThis work presents the molecular evolution along with the functional analysis of the genes located in the segmental duplications flanking the 7q11.23 region, involved in Williams-Beuren syndrome (WBS). The generation of the segmental duplications has been dated to the last 25 million years of evolution and an evolutionary model with specific rearrangements and mechanisms has been proposed. Clinical-molecular correlations in WBS patients have allowed to determine that haploinsufficiency at NCF1, a gene located in the duplications, is a protective factor for hypertension. A pathogenic model for hypertension has been proposed, implicating NAD(P)H oxidase and oxidative stress, and suggesting that novel therapeutic strategies could be used. In addition, the functional characterization of another gene of the duplications, GTF2IRD2, has been partially achieved. GTF2IRD2 has been shown to interact with other related transcription factors, to display variable subcellular localization and to lack DNA binding properties. These results contribute to a better knowledge of the mutational and pathogenic mechanisms of the WBS.

Pełny tekst źródłaThe usus auctoritas rule from the Twelve Tables was conceived by Jacques Cujas (16th century AD), and many authors thereafter, as an ancient norm that established a warranty against eviction granted by the seller when transferring the ownership of the thing to the buyer through the performance of mancipatio. According to this view, the very word auctoritas is taken to mean warranty, or else to imply an obligation to give warranty, and is intrinsically associated with mancipatio. But the fragment of the sources that state this rule USUS AUCTORITAS FUNDI BIENNIUM EST[O] were brough to us by Cicero and Gaius (the latter in the form of an interpretation of the norm), and both consider it to be an ancient Roman disposition that originally dealt with usucaption of immovable property only. To a certain extent, various ancient and modern jurists accept the latter interpretation. The object of this thesis is to provide new arguments to support the more natural interpretation adopted by Cicero and Gaius, i.e., that the rule in question deals specifically with an archaic and peculiar form of usucapio. The present work analyzes the emergence of private ownership of immovable property in Rome and its peculiarities: the quasi-religious augural system of land apportionment adopted by the fledging Roman state to assign a lot of land to every Roman citizen through the performance of acts of adsignatio (allotment); the sovereignty transferred by the pre-Roman gentes to the Quirites; the process by which land plots were gradually privatized and landowners acquired this once collective and quiritarian auctoritas, and the resulting land apportionment caused by the application of rules of private law based on the Twelve Tables conferring autonomy (auctoritas or title) to individuals and their families. In the final lines, an attempt is made to provide a logical analysis of the rule and to place it within the general conceptual framework of modern usucaption.

Pełny tekst źródłaCal esmentar que recenment s'ha desenvolupat una teoria general de sistemes (Kalman, Falb i Arbib - 1969; von Bertalanffy et al. - 1972, Aracil - 1978, Epelboin, Gabrielli i Keddam - 1984, entre d'altres) en el cas de no disposar d'una teoria concreta que descrigui el comportament del sistema i la seva evolució devant de pertorbacions externes.
La realització d'una experiència que permeti d'un cantó la regulació i llavors l'anàlisi de processos electròdics i per una altra banda, l'elaboració de models, els quals s'han de comparar amb les dades experimentals, requereix una descripció acurada de les lleis que governen el comportament elèctric i cinètic de la interfase.
Dins d'aquesta línia, el present treball es troba orientat a l'obtenció de funcions resposta de sistemes electroquímics tot utilitzant el mètode matemàtic de les transformades integrals. Si bé aquest mètode ha estat utilitzat en la resolució de determinats sistemes simples, la forma de tractar el problema, havia deixat pas a mètodes de linearització o de simulació numèrica per a resoldre problemes més complexes.
El mètode, que consisteix en transformar el conjunt d'equacions diferencials que descriuen l'evolució de les variables d'estat en un conjunt d'equacions integrals més fàcils de resoldre, s'ha generalitzat per a sistemes en què imposem unes poques hipótesis de caràcter físic. La funció resposta s'obté de forma exacta i permet garantir la bondat de possibles mètodes aproximats a propasar a partir de les equacions integrals. En efecte, en utilitzar el mètode de les aproximacions succesives, s'obtenen solucions analítiques per a aquestes equacions, o sinò sistemes d'equacions funcionals implícites més senzilles que el sistema, d'equacions integrals, tot retrobant les aproximarà ons possibles donades a la bibliografia per a estudiar els mateixos sistemes, la qual cosa ens dóna un marc general i unificat per a deduir de les equacions generals les solucions aproximades.
En el capítol II, s'ha fet un petit resum de l'estat actual de les teories físiques que ens descriuen les interfases electrificades, en particular les electròdiques. Això ens permet escollir quines són les variables d'estat que ens caracteritzaran la interfase.
El capítol III es centra en l'establiment de les equacions diferencials que ens descriuen l'evolució de les variables que ens caracteritza l'estat del sistema, així com de les condicions inicials i de contorn associades amb les característiques del procés i amb els lligams del sistema (variables de control).
Dins dels mètodes matemàtics més emprats per a resoldre aquest tipus d'equacions que trobem en el capítol III, en el capítol IV esmentem els més importants, i d'entre ells destaquem el mètode de les transformades integrals que es el que desenvolupem en els capítols V i VI, dedicats l'un a trobar les variables d' estat i l'altra a trobar les funcions resposta, en especial la intensitat i la càrrega total,d'un procés elemental de transferència
de càrrega, bescanviada a la interfase electròdica. Els sistemes estudiats, centrant-nos en llur geometria i règim hidrodinàmic, són l'elèctrode pla estacionari, l'elèctrode esfèric estacionari, l'elèctrode de gotes de mercuri, tant dins del model de pla en expansió com d'esfera, en expansió i l'elèctrod&ae disc rotatori.
En el capítol VII, es fa l'aplicació d'aquest formalisme a un exemple concret, el de la polarografia, que ha estat molt estudiat en casos sense complicacions degudes a l'adsorció a la interfase electròdica. En aquest cas s'han resol les equacions plantejades per a descriure el procés, amb les hipòtesis fetes en els darrers capítols, i quan l'adsorció dels components de la reacció segueixen una isoterma de Langmuir o de Frurnkin. Això ens permetrà valorar l'exactitud de les altres tècniques matemàtiques emprades per a resoldre aquest problema, generalment de forma aproximada, algunes de les quals es dedueixen de les equacions generals plantejades al aplicar el mètode d'aproximacions succesives per a resoldre les equacions integrals que surten. A més a més es veu l'aplicabilitat del mètode per a resoldre casos en què les tècniques convencionals no ho aconsegueixen o porten a equacions d'un grau molt elevat de complexitat per a dur-ho a la pràctica.
Aquest estudi es troba restringit als processos electròdics convencionals, puix que pot extendre's a la caracterització d'altres tipus de processos en què s'escaiguin hipòtesis similars. En particular, i a títol d'exemple, cal destacar l'ús d'aquest mètode en el futur esclariment de certs processos biològics, com ara el transport d'informació al cervell (González - 1984, Ghizmadzhev i Pastushenko - 1985) mitjançant el sistema nerviós.

Pełny tekst źródłaScholarly investigation of devotional images from the medieval period has never explored, in a European context, the question of Marian paintings functioning as portable relics. The model of the « picture-reliquary » : a single, diptych, or triptych panel comprsing the por-trait of the Virgin and Child painted on wood (or, more rarely, on gilded glass, verre églomisé) set in a large framework encrusted with relics (occasionally with precious stones) was particularly widespread in the territory of Little Poland from c. 1420. Polish reliquaries, known until the beginning of the 16th century, should be considered as an adaptation of iconic types and forms of Byzantine provenance, which were reinterpreted in the painting of the Italian Trecento. Of particular note is the Siennese model of the portable Marian altar piece made popular from the 1330s-40s. From the comparative study of the works, concerning their similarities and their antiquity, one envisages the advent of such a formal concept in Poland either directly from Italy, or by the intermediary of Bohemia.The diffusion of picture-reliquaries, typical of Tuscan art, forms part of the general movement toward a renewal of piety in central Europe in the 15th century, the devotio moderna. As a result, alongside singular representations, especially venerated in the course of liturgical or paraliturgical offices, one sees less costly reliquaries spread in private space. Appreciated in the intimate setting of convents – Franciscan and Dominican – as well as that of the daily life of the laity, these relics were used as domestic altars or as folding altars for travel. These images of religious affection constitute an artistic phenomenon of the late Middle Ages. And, several similar reliquaries known later do not guarantee a veritable continuity of the ancient model to the modern era
Die erhaltenen Überblicksdarstellungen und Spezialuntersuchungen zu den Frömmigkeitsbildern des Mittelalters haben sich niemals – im europäischen Kontext – mit der Frage derjenigen Mariendarstellungen auseinandergesetzt, die die Funktion von Tragereliquien inne hatten. Das Modell des Reliquien-Bildes – einfaches Tafel-bild, Diptychon oder Triptychon mit einer Darstellung der Jungfrau mit dem Kind, gemalt auf Holz (seltener auf Glas), umschlossen von einem breiten Rahmen, in den Reliquien (mitunter auch Edelsteine) eingefügt sind – verbreitet sich ca. ab 1420 ins-besondere auf dem Gebiet Kleinpolens. Diese polnischen Reliquiare, bekannt bis zum Beginn des 16. Jahrhunderts, können ohne Zweifel als Adaptation ikonischer und formaler Typen byzantinischer Provenienz angesehen werden, die in der Malerei des italienischen Trecento wiederinterpretiert wurden. Dabei handelt es sich vor allem um das Sieneser Model des marianischen Tragaltars, verbreitet seit den Jahren 1330-1340. Folgt man den vergleichenden Untersuchungen der erhaltenen Stücke mit Blick auf ihre übereinstimmenden Charakteristika und ihr Alter, wird das Auf-greifen eines solchen formalen Konzepts in Polen entweder direkt aus Italien oder indirekt über Böhmen wahrscheinlich.Die Ausbreitung dieser Tafel-Reliquiare, typisch für die toskanische Kunst, verbindet sich im 15. Jahrhundert in Mitteleuropa mit der umfassenden Bewegung einer Er-neuerung der Frömmigkeit, bekannt auch unter dem Namen devotio moderna. Dies führt dazu, daß neben einzelnen, vor allem im Rahmen liturgischer oder paraliturgi-scher Veranstaltungen verehrten Darstellungen, zunehmend weniger kostspielige Reliquiare auch in den privaten Raum vordringen. Gehütet sowohl in der Intimität der Klöster – franziskanisch und dominikanisch – als auch im täglichen Lebensraum der Laien, wurden sie als Hausaltäre oder auch als zusammenklappbare Reisealtäre verwendet. Diese Darstellungen religiösen Affekts stellen ein künstlerisches Phäno-men des Spätmittelalters dar. Einige der ähnlichen, allerdings später entstandenen Reliquiare garantieren allerdings keine überzeugende Kontinuität vom alten Modell hin zur Neuzeit

Entre os cantores populares, uma as principais ferramentas, tanto de ensino quanto autoaprendizagem, é a modelagem baseada em performances consolidadas de outros artistas. Mesmo após sua morte, Elis Regina (1945-1982) continua sendo considerada um dos mais importantes referenciais na interpretação da música brasileira, tanto do ponto de vista técnico-musical quanto cênico. A partir de duas gravações audiovisuais de Elis Regina para a canção Alô, alô, marciano de Rita Lee e Roberto de Carvalho, o presente estudo investigou as relações entre texto, música e cena na performance da cantora à luz de (1) oito princípios do ator, diretor de teatro, pedagogo e escritor russo Constantin Stanislavski (1863-1938), selecionados entre os princípios propostos no seu sistema para a atuação do ator e (2) conceitos-chave oriundos da análise do discurso e relações intertextuais. Observou-se uma imbricação entre elementos da performance da música popular e do teatro na construção e ressignificação de possíveis sentidos inerentes à canção, possibilitando caminhos para a construção e consolidação de performances bem fundamentadas do cantor de música popular.

Objective to establish a methodology for the oil spill monitoring on the sea surface, located at the Submerged Exploration Area of the Polo Region of Guamar?, in the State of Rio Grande do Norte, using orbital images of Synthetic Aperture Radar (SAR integrated with meteoceanographycs products. This methodology was applied in the following stages: (1) the creation of a base map of the Exploration Area; (2) the processing of NOAA/AVHRR and ERS-2 images for generation of meteoceanographycs products; (3) the processing of RADARSAT-1 images for monitoring of oil spills; (4) the integration of RADARSAT-1 images with NOAA/AVHRR and ERS-2 image products; and (5) the structuring of a data base. The Integration of RADARSAT-1 image of the Potiguar Basin of day 21.05.99 with the base map of the Exploration Area of the Polo Region of Guamar? for the identification of the probable sources of the oil spots, was used successfully in the detention of the probable spot of oil detected next to the exit to the submarine emissary in the Exploration Area of the Polo Region of Guamar?. To support the integration of RADARSAT-1 images with NOAA/AVHRR and ERS-2 image products, a methodology was developed for the classification of oil spills identified by RADARSAT-1 images. For this, the following algorithms of classification not supervised were tested: K-means, Fuzzy k-means and Isodata. These algorithms are part of the PCI Geomatics software, which was used for the filtering of RADARSAT-1 images. For validation of the results, the oil spills submitted to the unsupervised classification were compared to the results of the Semivariogram Textural Classifier (STC). The mentioned classifier was developed especially for oil spill classification purposes and requires PCI software for the whole processing of RADARSAT-1 images. After all, the results of the classifications were analyzed through Visual Analysis; Calculation of Proportionality of Largeness and Analysis Statistics. Amongst the three algorithms of classifications tested, it was noted that there were no significant alterations in relation to the spills classified with the STC, in all of the analyses taken into consideration. Therefore, considering all the procedures, it has been shown that the described methodology can be successfully applied using the unsupervised classifiers tested, resulting in a decrease of time in the identification and classification processing of oil spills, if compared with the utilization of the STC classifier

Dümmler in Monumenta Germaniae Historica, in the second volume of the section Poetae latini aevi Carolini. Due to its dependence from its hypotext, the first chapter of the thesis is about Historia Apollonii regis Tyri, the issues that the novel raises, and the possible answers that the critics gave to them. A general analysis of the cultural and historical background where Gesta Apollonii was written and also the story of the monastery where it was found, have been discussed in the second chapter; moreover, an important part of this chapter is dedicated to the study of the marginal and interlinear glosses of which the text is full. Part of these glosses was found in a codex of Boece’s De Consolatione Philophiae, written circa 1000 by abbot Froumund De Tegernsee; originally the codex was in the Fürstliche Öttingen-Wallersteinische Bibliothek in Bavaria, today it can be found in the Biblioteka Jagiellońska, in Cracow.In the third chapter more specifically, Gesta Apollonii text is compared to the novel -which it is based on- and to the several quotes from the Latin and Greek classical world. A paragraph is also dedicated to the possible historical accuracy of the characters mentioned in the story. After the thematic analysis of the text, the fourth chapter concerns the examination of the codicological and paleographic features of the manuscript and the presentation of the language, the style, and the metre of the work. In the fifth and last chapter, there is a French translation of Gesta Apollonii

Pełny tekst źródłaThis dissertation analyses the main causes and consequences of the expansive property cycle 1997-2006 in the metropolitan region of Barcelona. The chosen approach focuses on the housing needs, but taking also into account other main aspects of the residential system. Regarding the causes, the research examines the economic, financial, political, psychological and demographical factors. This dissertation argues that demographical factors do not explain the clear increase in housing prices during this period, although they have a very remarkable impact on the increase of the housing demand and supply. This comprehensive approach allows to study the complexity of the residential system in the metropolitan region of Barcelona as well as the differences with other parts of the territory and also with preceding property cycles. Regarding the consequences, this dissertation analyses how residential houses characteristics have evolved , as well as the perception of the people living in them. This research also examines the social inequalities and the territorial differences. Furthermore, it analyses the effects of the expansive property cycle on the population live cycle in the following aspects: the residential emancipation process, the residential integration of immigrants and the household indebtedness. Finally, the dissertation explores the evolution of urban segregation.

Pełny tekst źródłaThe northern coast of Rio Grande do Norte State is characterized by strong changes in coastal morphology, caused by various geological and climatic factors. In this region are installed the main socio-economic activities of the State, highlighting the oil industry, which exerts much of its activities in the coastal area studied. Erosion is a constant problem in this region because it affects the entire local populace to the destruction of houses and trade, rendering tourism, affecting the livelihood activities and industrial activities. The greatest risk is related to environmental damage that can be caused by the oil spill in this region. To understand what determines the changes in coastal morphology this Doctoral Thesis is proposed to identify the factors at local, regional and even global corroborate coastal dynamics to this coast in question. For this study, used several different products and tools for interpreting the conditions of the erosive effect that dominates the whole northern coast of the State, in an attempt to quantify and describe the causes and effects that affect the entire coastal zone monitored. The development of activities is built into the projects Rede 05 PETROMAR (CTPETRO-FINEP/PETROBRAS/CNPq), PETRORISCO, HIDROSEMA, PETROMAR e Rede 05/04 POTMAR (FNDCT/CTPETROFINEP/ CNPq), in the activities of multidisciplinary and inter-features in issues involving environmental monitoring and oil activity
O litoral setentrional do Estado do Rio Grande do Norte ? caracterizado por fortes mudan?as na sua morfologia costeira, ocasionadas por diversos fatores geol?gicos e clim?ticos. Nesta regi?o est?o instaladas as principais atividades socioecon?micas do Estado, destacando a Ind?stria Petrol?fera, que exerce boa parte de suas atividades na zona costeira estudada. A eros?o ? o constante problema nesta regi?o, pois afeta toda popula??o local com a destrui??o de moradias e com?rcio, inviabilizando o turismo, comprometendo as atividades de subsist?ncia e as atividades industriais. O risco maior est? relacionado ao dano ambiental que pode ser causado pelo derramamento de ?leo nesta regi?o. Para entender o que condiciona estas modifica??es na morfologia costeira esta Tese de Doutorado se prop?s em identificar os fatores de escala local, regional e at? global que corroboram com a din?mica costeira para este litoral em quest?o. Para tal estudo foram utilizados diversos produtos e diversas ferramentas para interpreta??o das condicionantes do efeito erosivo que predomina como um todo o litoral setentrional do Estado, na tentativa de quantificar e qualificar as causas e efeitos que afetam toda zona costeira monitorada.

Biodiversity, one of the fundamental properties of nature, is a source of immense economic potential. Brazil holds a rich biodiversity, and is considered one of the most important mega-diverse countries on the planet. Among the various links that make up this biodiversity Brazilian native flora noteworthy. Despite this, there have been few studies that promote intelligent and rational use of this genetic resource. Domestication and breeding of native plants, including those already known and used by local or regional populations, but without penetration at the national or international market is the great opportunity offered to the countries rich in genetic resources. Medicinal and aromatic plants represent a significant part of this potential market, and the lemongrass-Brazilian species (Lippia alba) is an important example of medicinal and aromatic plant, long used in folk medicine for his duties as soothing, antispasmodic, sedative, and produce various kinds of essential oils can be used by the perfume industry, food and cleaning products, beyond the control of pests and diseases in agriculture. Thus, the objective of this study was to evaluate the genetic variability, genetic parameters and the agronomic behavior of different accesses of L. alba, coming from the metropolitan region of the State of Rio de Janeiro. The experiment was conducted in November 2011 on Medicinal Plants Sector of Agronomy Institute of Rural Federal University of Rio de Janeiro, and crops were obtained in the spring of 2013 and summer of 2014. This study was divided into three chapters: Polymorphism in clones of L. alba coming from the metropolitan area of Rio de Janeiro (Chapter I); Genetic variation for morphological characters in clones of A. alba (Chapter II) and seasonality effect in producing chemotypes of L. alba (Chapter III). In Chapter I the accessions were grouped into dendrogram, five groups being formed and the group I met two similar access (UFRRJLA 17 and UFRRJLA 18). In Chapter II it was shown that the characters analyzed showed variability according to the season (spring or summer) confirming the strong influence of the environment on quantitative variables. The total dry matter and yield were higher in access UFRRJLA05 with citral chemotype, which showed the highest average values in the two seasons in which the data were evaluated. As for the essential oil yield and productivity stood out access UFRRJLA03 with limonene-carvone chemotype, both in spring and in summer.
A biodiversidade, uma das propriedades fundamentais da natureza, ? fonte de imenso potencial de uso econ?mico. O Brasil ? detentor de uma rica biodiversidade, e ? considerado um dos pa?ses megadiversos mais importantes do planeta. Dentre os v?rios elos que comp?e esta biodiversidade a flora nativa brasileira merece destaque. Apesar disto, poucos t?m sido os estudos que promovem a utiliza??o inteligente e racional destes recursos gen?ticos. A domestica??o e o melhoramento de plantas nativas, incluindo aquelas j? conhecidas e utilizadas por popula??es locais ou regionais, por?m sem penetra??o no mercado nacional ou internacional, ? a grande oportunidade que se oferece aos pa?ses ricos em recursos gen?ticos. As plantas medicinais e arom?ticas representam uma parte expressiva deste mercado em potencial, sendo que a esp?cie erva-cidreira-brasileira (Lippia alba) ? um exemplo importante de planta medicinal e arom?tica, h? muito tempo utilizada pela medicina popular por suas fun??es como calmante, antiespasm?dica, sedativo, al?m de produzir v?rios tipos de ?leos essenciais podendo ser utilizada pela ind?stria de perfumes, alimentos e produtos de limpeza, al?m do controle de pragas e doen?as na agricultura. Diante do exposto, o objetivo deste trabalho foi avaliar a variabilidade gen?tica e par?metros gen?ticos de acessos de L. alba e o comportamento agron?mico de diferentes clones oriundos da regi?o Metropolitana do Estado do Rio de Janeiro. O experimento foi instalado em novembro de 2011 no Setor de Plantas Medicinais do Instituto de Agronomia da Universidade Federal Rural do Rio de Janeiro, e as colheitas foram obtidas na primavera de 2013 e no ver?o de 2014. Este estudo foi dividido em tr?s cap?tulos: Polimorfismo em clones de L. alba oriundos da regi?o Metropolitana do Rio de Janeiro (Cap?tulo I) e Par?metros gen?ticos e avalia??o agron?mica em clones de L. alba (Mill) N.E.Brown em duas esta??es no ano (Cap?tulo II). No cap?tulo I os acessos foram agrupados em dendrograma, sendo formados cinco grupos e o grupo I reuniu os dois acessos similares (UFRRJLA 17 e UFRRJLA 18). No cap?tulo II foi demonstrado que os caracteres analisadas apresentaram comportamento vari?vel conforme a esta??o do ano (primavera ou ver?o) confirmando a forte influ?ncia do ambiente sobre as vari?veis quantitativas. A mat?ria seca total e a produtividade foram maiores no clone com quimiotipo citral (UFRRJLA05), com os maiores valores m?dios nas duas esta??es do ano em que os dados foram avaliados. J? para o rendimento e produtividade de ?leo essencial destacou-se o acesso com quimiotipo limoneno-carvona (UFRRJLA03), tanto na primavera quanto no ver?o

Pełny tekst źródłaBecause the penetration depth of Ground Penetrating Radar (GPR) signals is very limited in high conductive soils, the usefullness of this method in tropical regions is not yet completly known. The main objective of this researh is to test the usefullness of the method in Brazil. Two typical problems where GPR has been used in Europe and North American were choosed for this test: the first one is to characterize the internal structures of a sand body and the second problem is the localization of old buried pipes lines. The first test was done near the city of S?o Bento do Norte, in the northern coast of Rio Grande do Norte state, NE Brazil. In this region, there is a sand dune that is migrating very fast in the direction of adjacent settling areas. To characterize the internal structure of the dune and its relationship to the prevailing wind direction, as a preliminary step to understand the dune migration, GPR profiles using the 400 MHz frequency were performed in E-W, N-S, NE-SW, and SE-NW directions over the sand dune intersecting at the top of the dune. The practical resolution of the GPR data is around 30 cm; this was sufficient to distinguish individual foresets inside the dune. After applying the elevation correction to the data, we identified that dips of bedding structures are smallest for the N-S profile, which is perpendicular to the dominant wind direction, largest for the E-W profile, and intermediate for the SW-NE and SE-NW profiles. Foresets in the E-W profile dip with angles varying from 2 to 6 degrees. In the E-W profile, the water table and a horizontal truncation interface separating two generations of dunes were identified, as well as an abrupt directional change in the foreset patterns associated to a lateral contact between two dune generations, the older one extending to the west. The used high frequency of 400 Mhz does not allow a penetration deep enough to map completely these internal contacts. The second test was done near Estreito, a small town near Carna?bais city, also in Rio Grande do Norte state. In this locality, there are several old pipe lines buried in area covered by plantations where digging should be minimized. Several GPR profiles using the 400 and 200 MHz frequency were performed trying to intercept perpendicularly the possible pipe lines. Because of the high conductivity of the soil, the raw original data can hardly be use to identify the pipe lines. However, after an adequate processing over the 200 MHz profiles, six pipe lines were identified. As a global result of the tests, GPR can be very usefull if the conductivity of the ground is low or, in the case of medium conductivities of the soils, if adequate processing is performed
O principal objetivo deste trabalho, ? testar o m?todo GPR (Ground Penetrating Radar) em ambientes com clima tropical. Desta forma, foram escolhidas duas localidades distintas que apresentam problemas considerados padr?es para a aplica??o do GPR. A natureza n?o invasiva deste m?todo, aliada ao baixo custo, rapidez e facilidade de opera??o, torna-o adequado para os trabalhos aqui propostos. A primeira localidade est? situada no munic?pio de S?o Bento do Norte e o problema relacionado a ela consiste na caracteriza??o de estruturas internas de dunas. Se??es de GPR com antena de 400 Mhz foram levantadas nas dire??es E-W, N-S, NE-SW e SE-NW. Estes perfis interceptaram-se no topo da duna e possibilitaram estabelecer rela??es entre a sua estrutura interna e a sua dire??o de migra??o, associada ao vento dominante na ?rea. Foi poss?vel identificar tamb?m contatos laterais entre dunas de diferentes gera??es, assim como bounding surfaces, n?vel fre?tico e mergulho de camadas. Na segunda localidade, de nome Estreito (pr?ximo ao munic?pio de Carnaubais), foram levantadas se??es de GPR com antenas de 200 Mhz e 400 Mhz para detectar dutos antigos de petr?leo enterrados em uma ?rea agricult?vel. Os perfis de GPR foram realizados perpendicularmente ? suposta dire??o dos dutos e, da sua interpreta??o, determinous-se a posi??o de seis oleodutos de diferentes di?metros (4", 10" e 16") enterrados, cujas posi??es exatas eram desconhecidas, assim como a produndidade em que estes se encontravam (variando de 1,2m e 1,5m). No tratamento dos dados foi adotado um processsamento semelhante ?queles utilizado nos m?todos s?smicos (ajuste do tempo zero, ganho, migra??o, corre??o topogr?fica, dewow, deconvolu??o e filtros passa-banda). Este processamento permitiu estabelecer rela??es entre os refletores contidos nas se??es de GPR e estruturas geol?gicas (ou n?o) presentes nos ambientes. A corre??o topogr?fica possibilitou identificar com precis?o estruturas planas (como o n?vel fre?tico), ao passo que a migra??o dos dados proporcionou a exata posi??o dos dutos

The aetiology of autoimmunes disease is multifactorial and involves interactions among environmental, hormonal and genetic factors. Many different genes may contribute to autoimmunes disease susceptibility. The major histocompatibility complex (MHC) genes have been extensively studied, however many non-polymorphic MHC genes have also been reported to contribute to autoimmune diseases susceptibility. The aim of the present study was to evaluate the influence of SLC11A1 gene in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Ninety-six patients with SLE, 37 with RA and 202 controls enrolled in this case-control study, were evaluated with regard to demographic, genetic, laboratorial and clinical data. SLE mainly affects females in the ratio of 18 women for each man, 88,3% of the patients aged from 15 to 45 years old and it occurs with similar frequency in whites and mulattos. The rate of RA between women and men was 11:1, with 77,1% of the cases occurring from 31 to 60 years. The genetic analysis of the point mutation -236 of the SLC11A1 gene by SSCP did not show significant differences between alleles/genotypes in patients with SLE or RA when compared to controls. The most frequent clinical manifestations in patients with SLE were cutaneous (87%) and joint (84.9%). In patients with RA, the most frequent out-joint clinical manifestation were rheumatoid nodules (13,5%). Antinuclear antibodies were present in 100% of the patients with SLE. There was no significant relation between activity of disease and presence of rheumatoid factor in patients with RA, however 55,6% of patients with active disease presented positive rheumatoid factor. Significant association between alleles/genotypes of point mutation -236 and clinical manifestations was not found
A etiologia das doen?as autoimunes ? multifatorial, resultando de intera??es complexas de fatores ambientais, hormonais e gen?ticos. Diversos genes contribuem para a suscetibilidade ?s doen?as autoimunes. Os genes do complexo principal de histocompatibilidade (MHC) tem sido amplamente estudados, por?m genes n?o-MHC tamb?m parecem contribuir para a suscetibilidade a autoimunidade. O presente estudo tem por objetivo avaliar a influ?ncia do gene SLC11A1 nas doen?as autoimunes lupus eritematoso sist?mico (LES) e artrite reumat?ide (AR). Foram arrolados 96 pacientes com LES, 37 com AR e 202 controles saud?veis, em estudo caso-controle, avaliando os dados demogr?ficos, gen?ticos e cl?nico-laboratoriais. LES afetou principalmente o sexo feminino na raz?o de 18 mulheres para 1 homem, sendo 88,3% na faixa et?ria entre 15 e 45 anos e ocorreu com freq??ncias semelhantes em brancos e pardos. A raz?o encontrada de AR entre mulheres e homens foi 11:1, com 77,1% dos casos ocorrendo entre 31 e 60 anos. A an?lise gen?tica do ponto de muta??o -236 da regi?o promotora do gene SLC11A1 por SSCP, n?o mostrou diferen?as significativas entre as freq??ncias de alelos ou gen?tipos de pacientes com LES ou AR em rela??o aos controles. As manifesta??es cl?nicas mais freq?entes nos pacientes com LES foram a cut?nea (87%) e articular (84,9%). Na AR a manifesta??o cl?nica extra-articular mais encontrada foi a presen?a de n?dulo reumat?ide (13,5%). A pesquisa do anticorpo anti-nuclear (FAN) foi positiva em 100% dos pacientes com LES. N?o houve rela??o significativa entre doen?a ativa e presen?a de fator reumat?ide em pacientes com AR, no entanto, 55,6% dos pacientes com doen?a ativa, apresentavam fator reumat?ide positivo. N?o foi encontrada associa??o significativa entre as manifesta??es cl?nicas ou achados laboratoriais e alelos/gen?tipos do ponto de muta??o -236

Seu objetivo consiste, por um lado, em identificar se as regras de conflito atualmente existentes na Lei de Introdução às Normas do Direito Brasileiro (1942) são suficientes ou não para uma proteção efetiva do vulnerável nas relações privadas internacionais, e por outro lado, em se constatando uma precariedade na proteção do vulnerável, estabelecer uma proposta de reconstrução axiológica das regras do direito internacional privado brasileiro para restabelecer a igualdade e o diálogo com a Constituição Federal (1988). Para tanto, a pesquisa está disposta em três capítulos. No primeiro capítulo, é apresentada a crise do direito internacional privado brasileiro a partir do paradigma da regra conflitual tradicional e da justiça formal, apontando-se a inadequação da Lei de Introdução às Normas do Direito Brasileiro para a solução dos problemas contemporâneos de direito internacional privado. No segundo capítulo, apresenta-se a proposta de um recomeço, a partir das intersecções do direito internacional privado com o direito privado e com o direito público, especialmente no que diz respeito à eficácia plena dos direitos fundamentais e dos direitos humanos nas relações privadas, em busca de uma justiça material. No terceiro capítulo, é proposta a reconstrução teleológica do direito internacional privado, a ser orientada pelos valores constitucionais. Sendo o direito internacional privado essencialmente um direito dos diferentes, sobressai o princípio da igualdade e a proteção dos vulneráveis como concretização dos valores constitucionais. Ao final, são propostas duas soluções para a superação da crise: primeiro, há a proposição de alteração legislativa, para que se estabeleça a regra de conflito com a conexão da lei mais favorável ao vulnerável; segundo, enquanto não é realizada a alteração legislativa, propõe-se interpretação sistemático-teleológica do artigo 17, da Lei de Introdução às Normas do Direito Brasileiro (1942), para que funcione como cláusula aberta para a concretização dos direitos fundamentais e dos direitos humanos nas relações privadas internacionais, possibilitando a aplicação da lei mais favorável ao vulnerável como forma de efetivação positiva da ordem pública constitucional.
This thesis aims at the analysis of the protection of the vulnerable in the Brazilian private international law. Its aim is, first, to identify if the conflictual rules currently existing in the Introductory Act to Brazilian Law Rules (1942) are or are not sufficient for an effective protection of the vulnerable in international private relations, and on the other hand, if finding the protection of the vulnerable precarious, to establish a proposal of axiological reconstruction of the rules of Brazilian private international law to restore equality and dialogue with the Federal Constitution (1988). Therefore, the research is arranged in three chapters. In the first chapter, the crisis of the Brazilian private international law is presented from the paradigm of traditional conflictual rule and formal justice, pointing out the inadequacy of the Introductory Act to Brazilian Law Rules (1942) to the solution of contemporary problems of private international law. The second chapter presents the proposal of a new beginning, through the intersections of private international law with private law and public law, especially with regard to the full effectiveness of fundamental rights and human rights in private affairs, in search of a material justice. In the third chapter it is proposed a teleological reconstruction of private international law, to be guided by constitutional values. Private international law being essentially a right of the different, it stands the principle of equality and the protection of the vulnerable as achievements of constitutional values. Lastly, two solutions are proposed to overcome the crisis: first, there is the proposal of a legislative change, in order to establish the conflictual rule with the connection to the most favorable law to the vulnerable; second, while the legislative amendment is not performed, it is proposed a systematic-teleological interpretation of Article 17 of the Introductory Act to Brazilian Law Rules (1942), to function as an open clause to the achievement of fundamental rights and human rights in international private relations, enabling the application of the most favorable law to the vulnerable as a form of positive performance of the constitutional public order.

The structural framework of the sedimentary basins usually plays an important role in oil prospects and reservoirs. Geometry, interconectivity and density of the brittle features developed during basin evolution could change the permo-porous character of the rocks involved in generation, migration and entrapment of fluid flow. Once the structural characterization of the reservois using only sub-surface data is not an easy task, many studies are focused in analogous outcrops trying to understand the main processes by which brittle tectonic is archieved. In the Santana do Acara? region (Cear? state, NE Brazil) a pack of conglomeratic sandstone (here named CAC) has its geometry controlled mainly by NE trending faults, interpreted as related to reactivation of a precambrian Sobral Pedro II Lineament (LSP-II). Geological mapping of the CAC showed a major NE-SW trending synform developed before its complete lithification during a dextral transpression. This region was then selected to be studied in details in order of constrain the cretaceous deformation and so help the understanding the deformation of the basins along the brazilian equatorial margin. In order to characterize the brittle deformation in different scales, I study some attributes of the fractures and faults such as orientation, density, kinematic, opening, etc., through scanlines in satellite images, outcrops and thin sections. The study of the satellite images showed three main directions of the macrostructures, N-S, NE-SW and E-W. Two of theses features (N-S and E-W) are in aggreement with previous geophysical data. A bimodal pattern of the lineaments in the CAC?s basement rocks has been evidenciated by the NE and NW sets of structures obtained in the meso and microscale data. Besides the main dextral transpression two others later events, developed when the sediments were complety lithified, were recognized in the area. The interplay among theses events is responsible for the compartimentation of the CAC in several blocks along within some structural elements display diferents orientations. Based on the variation in the S0 orientation, the CAC can be subdivided in several domains. Dispite of the variations in orientations of the fractures/faults in the diferents domains, theses features, in the meso and microscopic scale, are concentrated in two sets (based on their trend) in all domains which show similar orientation of the S0 surface. Thus the S0 orientation was used to group the domains in three major sets: i) The first one is that where S0 is E-W oriented: the fractures are oriented mainly NE with the development of a secondary NW trending; ii) S0 trending NE: the fractures are concentrated mainly along the trend NW with a secondary concentration along the NE trend; iii) The third set, where S0 is NS the main fractures are NE and the secondary concentration is NW. Another analized parameter was the fault/fracture length. This attribute was studied in diferent scales trying to detect the upscale relationship. A terrain digital model (TDM) was built with the brittlel elements supperposed. This model enhanced a 3D visualization of the area as well as the spatial distribution of the fault/fractures. Finally, I believe that a better undertanding of the brittle tectonic affecting both CAC and its nearby basement will help the future interpretations of the tectonic envolved in the development of the sedimentary basins of the brazilian equatorial margin and their oil reservoirs and prospects, as for instance the Xar?u field in the Cear? basin, which subsurface data could be correlated with the surface ones
Grande parte dos prospectos e reservat?rios de petr?leo tem o seu arcabou?o estrutural como um fator de grande import?ncia. A geometria, interconectividade e densidade dos elementos da tect?nica fr?gil (falhas, fraturas, etc.), t?m grande influ?ncia no car?ter permo-poroso do meio e, por conseguinte, no fluxo de fluidos. Tendo em vista as dificuldades encontradas para a caracteriza??o da deforma??o fr?gil, unicamente com dados de subsuperf?cie, v?rios estudos est?o sendo direcionados ao detalhamento das por??es emersas das bacias e de seus substratos, em busca de an?logos da deforma??o. Na Regi?o de Santana do Acara? aflora um corpo aren?tico conglomer?tico (CAC) cuja geometria ? controlada por falhas, principalmente de trend NE, interpretadas como decorrentes da reativa??o do Lineamento Sobral Pedro II (LSP-II). A fim de caracterizar a deforma??o fr?gil em diferentes escalas, estudou-se os atributos do fraturamento tais como: orienta??o, densidade, cinem?tica, abertura, etc., atrav?s de scanlines em imagens de sat?lite, afloramentos e se??es delgadas. O estudo das imagens de sat?lite mostrou que as macroestruturas da ?rea apresentam tr?s dire??es preferenciais sendo elas N-S, NE-SW e E-W. As dire??es N-S e E-W s?o compat?veis com movimento de blocos observados por estudos gravim?tricos. O estudo do CAC mostrou que ele apresenta uma estrutura sinformal alongada na dire??o NE-SW, fruto de uma tect?nica transpressional dextral desenvolvida enquanto o corpo ainda n?o estava completamente litificado. Foi evidenciada a exist?ncia de duas outras fases de reativa??o, ocorridas quando o CAC j? se encontrava totalmente litificado. A tect?nica fr?gil compartimentou o CAC em blocos, cujo basculamento, gera varia??es na orienta??o de alguns de seus elementos (S0, por exemplo). Com base na varia??o da orienta??o de S0, o CAC pode ser subdividido em v?rios dom?nios. Do ponto de vista da orienta??o do fraturamento/falhamento os estudos na meso e microescala mostraram que as rochas do embasamento do CAC possuem um padr?o de lineamentos basicamente bimodal (NE e NW), enquanto no CAC observou-se que, embora haja uma distribui??o do fraturamento em varias dire??es, em todos os dom?nios, a concentra??o ao longo de dois trends espec?ficos nos dom?nios que apresentam as mesmas orienta??es de S0 ? marcante, caracter?stica e distinta. Os diversos dom?nios s?o agrupados em tr?s conjuntos, onde o conjunto que apresenta S0 praticamente NW mostra um fraturamento principal com trend NE e secund?rio NW, enquanto que o conjunto apresentando S0 com dire??o NE, mostra uma maior concentra??o dos lineamentos ao longo dos trend NW e secundariamente com trend NE. No conjunto de dom?nios com S0 praticamente N-S, o trend principal do fraturamento ? NE e o secund?rio NW. Outros atributos do fraturamento, tal como o seu comprimento, foi tamb?m analisado e comparado em diversas escalas buscando verificar se existia uma rela??o de upscale. O desenvolvimento de um modelo digital de terreno, com as estruturas fr?geis superpostas, propiciou uma vis?o tridimensional da regi?o estudada. O entendimento da deforma??o fr?gil que atingiu o corpo aren?tico-conglomer?tico (CAC) da regi?o de Santana do Acara? (CE) e seu substrato reveste-se de import?ncia pela presen?a de reservat?rios fraturados nas bacias da margem equatorial brasileira (Campo de Xareu na bacia do Cear?, por exemplo), cujos dados podem ser confrontados com os de superf?cie

Pełny tekst źródłaAquesta Tesi Doctoral se centra a analitzar, comparar, determinar i sintetitzar diferents aspectes geomètrics, de proporcions i d’elements arquitectònics que són comuns a les Esglésies Ortodoxes Romaneses, a la històrica regió de Valàquia, i que han creat un patró arquitectònic característics dels edificis de culte ortodox a Romania. La tesi està subjecte a Menció Internacional, pel que es redacta en català i parcialment en romanès. La tesi realitza una immersió en els fonaments de la litúrgia ortodoxa romanesa i en l’arquitectura dels seus temples històrics per tal d’indagar en les raons que n’expliquen les característiques particulars. La tesi analitza la realitat del fenomen religiós a la Romania d’avui, emmarcant-lo en la història política i social del país, permetent donar idea de la dimensió d’aquest fenomen; un fenomen que resulta insòlit, per als temps actuals, si se’l compara amb la situació imperant a la resta de confessions cristianes. La visita a un conjunt d’esglésies que conforma una llista que es considera prou representativa ha permès assolir un coneixement de primera mà del tema objecte d’estudi. A banda de contrastar mides i actualitzar una informació bibliogràfica que sovint resultava obsoleta, la visita dóna accés a una visió perceptiva i sensible de la realitat espacial d’aquests edificis. Es constata que la representació tècnica convencional no explica prou bé aquesta realitat ni ho fan tampoc els estudis plantejats des del prisma estricte de la història de l’art. Es plantegen doncs vies de representació alternatives, que es consideren més adequades a la realitat de l’arquitectura d’aquestes esglésies. Es tracta de vies que passen pel modelatge tridimensional i per l’elaboració de fotomuntatges panoràmics. Es fa notar el caràcter poc monumental d’aquestes esglésies i el seu plantejament bàsicament funcional. Sota el principi de buscar la proximitat amb el creient i amb una marcada voluntat de donar un servei, es va repetint el mateix tipus amb ben poques variacions. En la mateixa línia, es remarquen les dimensions relativament reduïdes d’aquests temples, particularment pel que fa als seus espais interiors. En aquest sentit i des del vessant més purament arquitectònic, es detallen la quantitat d’efectes escenogràfics i de recursos que, tot i les seves dimensions reduïdes, es posen en joc en la conformació espacial de l’interior de les esglésies analitzades. Des del punt de vista d’aquesta tesi, és en la valoració d’aquests espais interiors on cal fixar-se a l’hora d’estudiar i classificar aquests edificis. Per fer-ho, es proposa un seguit de paràmetres que en facilitin la comparació. En un moment en què l’expansió del credo ortodox romanès reclama la construcció de noves esglésies, el coneixement que la tesi aporta sobre l’arquitectura dels temples històrics de Valàquia vol contribuir a afrontar-ne la construcció amb criteris més fonamentats. Alhora, aquest millor coneixement de les lògiques arquitectòniques que motiven la seva geometria hauria de fer possible avançar cap a noves formalitzacions que, sense incomplir amb els trets essencials, s’adaptin millor a les exigències del món d’avui i a les tècniques constructives del nostre temps.

Pełny tekst źródłaUltrasonography is an innocuous noninvasive diagnostic tool, which is easy to perform and low-cost, and it is widely used in the medical field, indicated especially in the exam of soft tissues. Despite this, it is not usually requested by dental surgeons in the diagnostic investigation of intraoral lesions. The aim of this study was to determine how much this resource contributes to establishing the final diagnosis of nodules located in the oral and maxillofacial region. Accordingly, we evaluated the indication of use and reliability of the procedure in Dentistry, considering the usefulness to reach the definitive diagnosis of these alterations. Sixty-five patients with submucosal or subcutaneous nodules were recruited for the study. They had been indicated for and subjected to regional ultrasonography, since it was not possible to establish a conclusive diagnosis of the lesions only by clinical examination. Ultrasonography was carried out in an imaging diagnostic center utilizing the same apparatus Toshiba Aplio 80 Japan. The imaging reports were prepared by a single examiner, with wide experience in the interpretation of images of the oral and maxillofacial region. Of the total patients, 43 had a biopsy for histopathologic confirmation of the final diagnosis. In 22 individuals, it was not necessary to perform surgery, since imaging allowed the establishment of the diagnosis and management of the patient. Two investigators evaluated the results obtained with ultrasonography and estimated the scores, which were zero (ultrasonographic diagnosis differed from the final), 1 (contributed to the management of the patient) and 2 (defined the definitive diagnosis). The zero score accounted for 12.3% of the examinations performed, while 41.5 and 46,1% of patients had scores of 1 and 2, respectively, totaling 87.6% of cases where imaging was helpful. The procedure facilitated the diagnosis of vascular lesions in 93.3%, helped with the management of 87.5% of patients with both malignant and benign neoplasms, and had a role in establishing the final diagnosis in 76.5% of cases of mucus retention phenomena. The results obtained were in accordance to findings in the literature, which demonstrated that ultrasonography is an effective resource in determining the final diagnosis or in the management of patients with nonspecific nodular lesions in the soft tissues of the oral and maxillofacial region

Pełny tekst źródłaLes aigües continentals són uns components molt actius en cicle del carboni (C). Aquests, transformen, emmagatzemen i emeten la meitat de C que reben dels ecosistemes terrestres adjacents. No obstant, encara existeix una elevada incertesa pel que fa als patrons espaciotemporals, factors de control i principals fonts dels fluxos gasosos de C en xarxes fluvials. Els resultats d’aquesta tesi mostren que les estructures de retenció d’aigua de mida petita (ERMP), les quals són molt comuns en rius Mediterranis, van atenuar les condicions turbulents que caracteritzen les seccions del riu amb aigües corrents. Com a conseqüència, les emissions difusives de CO2 des d’aigües represades van ser inferiors a aquells des d’aigües corrents. Contràriament, la presència de ERMP no va suposar un efecte negatiu sobre les emissions de CH4. Tanmateix, fonts diferents al metabolisme intern (això és, entrades externes i reaccions geoquímiques o fotoquímiques internes) van sostenir les emissions de CO2 de la xarxa fluvial. La magnitud i fonts d’aquestes van dependre de les condicions hidrològiques en el cas dels trams d’aigües corrents, mentre que es van mantenir relativament estables i independents de la hidrologia en aquelles seccions de riu reprssades. Les lleres dels rius intermitents romanen actives pel que fa al processat i emissió de CO2 a l’atmosfera una vegada el flux superficial d’aigua cessa. Per contra, el flux d’emissió de CH4 des de les lleres seques va ser indetectable en gairebé tots els casos, probablement degut a les condicions d’alta aeració que limiten els requisits redox per a la producció microbiana de CH4. El flux d’emissió de CO2 des de les lleres seques va doblar a l’emès des de les lleres amb aigües corrents i va ser comparable a l’emès des dels sòls terrestres adjacents. No obstant, les lleres seques i els sòls terrestres adjacents van resultar ser mol diferents des d’un punt de vista fisicoquímic, mostrant així diferències en els principals factors i fonts que en regulen les emissions de CO2. En resum, les principals troballes fetes en aquesta tesi apunten cap a una necessitat clara de substituir els models continus i limitats espacialment per aquells models que incorporen discontinuïtats espaciotemporals (això és, represament del riu o intermitència del règim hidrològic) per tal d’entendre en millor mesura les dinàmiques dels fluxos gasos de C en xarxes fluvials.

Pełny tekst źródłaModern towns are generally pictured like a group of inhabitants enjoying common privileges and living behind fortifications. This simple definition sounds limited and restrictive. Indeed, at that time the urban territory was not limited to the symbolical limits represented by the fortifications. Morphologically, fiscally as well as economically, the suburbs were the natural extensions of the city beyond the original territory initially defined by the the plans of the walls. This doctoral thesis indeed highlights the study of these spaces which have been ignored in the historiography and thereby redefines the notion of the modern city in France

Pełny tekst źródłaThe study area is located in the northern coast of Rio Grande do Norte State comprising the mouth of A?u-Piranhas river including the cities of Porto do Mangue e Areia Branca. The local geological setting comprises Cretaceous, Tertiary and Quaternary geological units of the Potiguar Basin. One is about a region of high morphologic instability due to action of the rigorous dynamic coastal processes, beyond the intense human activities mainly for the performance of the petroliferous industry, salt farms and tanks of shrimp industry.For the accomplishment of this work Landsat 5 TM and Landsat 7 ETM + from four distinct dates were used as cartographic base, in which one applied techniques of digital processing to elaborate thematic maps of the existing natural resources to support the geologic and geomorphologic characterization and the soil and landuse maps. The strategy applied was the interpretation of multitemporal images from aerial and orbital remote sensors alIied to the terrain truth recognition, integrated through a Geographic Information System. These activities had alIowed the production of Sensitivity Maps of the Coast to Oil Spilling for the area, on the basis of the Coastal Sensibility Index. Taking into account the seasons were created maps to distinct datas: July 2003 represents the winter months that presented a sensibility lower when compared with the month of December 2003. For the summer months greater sensitivity is due to the hydrodynamic data that suggest a lesser capacity of natural cleanness of the oil and its derivatives in spilling case.These outcomes are an important and useful database to support an assessment to a risk situation and to taking decision in the face of an environmental disaster with oil spilling in coastal area, alIowing a complete visualization of the area and identifying all portions in the area with thei environmental units and respective Coastal Sensibility Index.

Considerando-se a sazonalidade local foram confeccionados mapas para datas distintas, Julho de 2003, representando os meses de inverno que apresentou uma sensibilidade mais baixa quando comparado ao m?s de Dezembro de 2003. Para os meses de ver?o a maior sensibilidade deve-se aos dados hidrodin?micos que sugerem uma menor capacidade de limpeza natural do ?leo e seus derivados em caso de derramamento. Os dados coletados e as informa??es geradas representam uma importante base de dados necess?rios ?s tomadas de decis?es para os casos de conten??o de ?leo e seus derivados derramados em ?reas costeiras, baseados nas caracter?sticas das diferentes unidades geoambientais e seus respectivos ?ndices de Sensibilidade do Litoral (ISL)

Pełny tekst źródłaEl estrés y el duelo asociados a la migración y la falta de equidad en el acceso a los servicios sanitarios influyen negativamente en la salud mental. El objetivo de esta tesis es determinar si la exposición a antidepresivos y antipsicóticos es diferente entre inmigrantes y autóctonos de una región española. Se realizaron cuatro estudios entre 2007 y 2009 a partir de las dispensaciones de fármacos. Todos los grupos inmigrantes recibieron menos antidepresivos y antipsicóticos que la población autóctona de igual edad y sexo, con diferencias entre grupos. El riesgo relativo de abandono de los antidepresivos fue un 28% mayor en los inmigrantes; el 36,8% abandonó durante el primer mes y solo el 29,5% mantuvo una buena adherencia, frente al 38,8% de autóctonos. La adherencia a antipsicóticos fue del 19,1% y 40,4% para inmigrantes y autóctonos respectivamente. Las diferencias encontradas indican la necesidad de profundizar en las causas para establecer las políticas de actuación adecuadas.
Immigration is a stressful process and a risk factor for mental illness. Inequality in health care access can worsen this situation. The aim of this study is to determine if there are differences between immigrants and non-immigrants in the use of and compliance with antidepressant and antipsychotic treatment in a Spanish region. It includes four studies on pharmaceutical dispensing done between 2007 and 2009. All immigrant groups have lower antidepressant and antipsychotic consumption than the native population of the same age and sex, with differences between groups. The relative risk of abandoning treatment is 28% higher in immigrants; 36,8% filled only one prescription and 29,5% presented good compliance compared with 38,8% of natives. Antipsychotic adherence was appropriate for 19,1% of immigrants and 40,4% of native. More research is needed to understand the causes of these differences and to ensure adequate access and use of mental health services.

Law No. 8213/91, known as the Quota Law was formulated as a tool to implement the National Policy on Employment Dues for Persons with Disabilities. This law today is one of the main means for the insertion of PCDs (Persons with Disabilities) into the labor market. However, the implementation of this law occurs in the face of some difficulties, such as accessibility, for example, in addition to prejudice regarding PCDs in the social environment, which ultimately interferes with its effectiveness. The purpose of this paper is to understand the meanings attributed to the Quota Law by HR Managers who act or have acted in organizations that apply the Quota Law. In order to achieve this goal, nine interviews were conducted, of which eight interviews were conducted with managers, some of whom were in full exercise until the date of the interview, and others who had recently left the organization in which they performed HR functions, and was also interviewed the coordinator of the State Nucleus for Assistance to the Disabled (NEAD). Besides the interviews, this work made use of the technique of observation and the analysis of the collected material occurred through the Nuclei of Meaning. The results show that the managers interviewed still perceive the Quota Law as a merely punitive Law, however, they understand the Quota Law also, as an important one, if not unique, tool for the insertion of PCDs into the labor market. With this, it can be said that the meanings that managers attribute to the Quota Law are loaded with prejudice and the way the Quota Law is signified by these managers reflects in the way they execute this Law, and it can be affirmed that the issue is cultural.
A lei n? 8213/91, conhecida como Lei de Cotas foi formulada como ferramenta para implementar a Pol?tica Nacional de Cotas Empregat?cias para Portadores de Defici?ncia. Esta lei hoje ? um dos principais meios para a inser??o das PCDs (Pessoas com Defici?ncia) no mercado de trabalho. Contudo, a implementa??o desta lei ocorre diante de algumas dificuldades, como a acessibilidade, por exemplo, al?m do preconceito no que tange ?s PCDs no meio social, o que acaba interferindo na efetividade da mesma. Este trabalho tem como objetivo, compreender os sentidos atribu?dos ? Lei de Cotas pelos Gestores de RH que atuam, ou atuaram, em organiza??es que se aplica a Lei de Cotas. Para atingir este objetivo foram realizadas nove entrevistas, sendo oito entrevistas realizadas com gestores, dos quais alguns estavam em pleno exerc?cio da fun??o at? a data da entrevista e outros que haviam sa?do recentemente da organiza??o em que exercia a fun??o de gestor de RH, e ainda, foi entrevistada a coordenadora do N?cleo Estadual de Atendimento ao Deficiente (NEAD). Al?m das entrevistas este trabalho fez uso da t?cnica de observa??o e a an?lise do material levantado ocorreu por meio dos N?cleos de Significa??o. Os resultados mostram que os gestores entrevistados ainda percebem a Lei de Cotas como uma Lei meramente punitiva, entretanto, entendem a Lei de Cotas tamb?m, como uma importante, sen?o ?nica, ferramenta para a inser??o das PCDs no mercado de trabalho. Com isso, pode-se afirmar que os sentidos que os gestores atribuem a Lei de Cotas s?o carregados de preconceito e a forma como a Lei de Cotas ? significada por esses gestores reflete na forma como executam essa Lei, e ainda, pode-se afirmar que a quest?o ? cultural

Neste trabalho foram obtidas Secções de Choque Totais Absolutas (SCTA) para moléculas de Etanol e Metanol utilizando um aparelho desenvolvido no Laboratório de Espectroscopia Atômica e Molecular do DF/UFJF, que emprega a técnica de transmissão linear. As medidas foram realizadas para o Metanol e Etanol cobrindo as energias de impacto de 70, 80, 90, 100, 150, 200, 250, 300, 350, 400 e 500 eV e também de 60 eV para o Etanol. A resolução de energia em todas as medidas foi de 0,6 eV (FWHM) e a incerteza no cálculo das SCTs foi estimada em 5%. A faixa de pressão na célula de espalhamento foi mantida entre 1 a 4mTorr. Os elétrons que sofreram processos de colisões inelásticas podem ser descriminados daqueles que não sofreram nenhum processo de interação com o alvo por um analisador cilíndrico dispersivo 127º, que tem a finalidade de selecionar os elétrons que serão detectados pelo Coletor de Faraday. Medindo a intensidade do feixe de elétrons atenuados, a SCTA pode ser obtida aplicando a Lei de Lambert Beer. Os dados foram obtidos através de um procedimento estatístico envolvendo uma série de 4 a 7 sessões de medidas, os valores obtidos foram utilizados para encontrar a SCT para uma determinada energia definida. Além das medidas experimentais, nós determinamos SCT utilizando a Regra da Aditividade. Nós também avaliamos nossos dados experimentais usando uma fórmula de dois parâmetros (Curva de Born) para cada gás. Nossos dados experimentais concordam com a maioria dos dados publicados na literatura. Não existem dados reportados na literatura de SCT para a molécula do Etanol (C2H5OH).
We have measured the absolute Total Cross Section (TCS) for methanol and ethanol molecules using an apparatus manufactured at the Molecular Spectroscopy Laboratory at DF/UFJF, which employ the linear transmission technique. The experimental data were taken at incident electron energies of 70, 80, 90, 100, 150, 200, 250, 300, 350, 400 and 500 eV for methanol and ethanol and also of 60 eV for ethanol. The energy resolution in all measurements was 0,6 eV (FWHM) and the overall systematic uncertainty at the TCS were evaluated to be less than 5%. The pressure range in the scattering cell was chosen between 1 and 4mTorr. Those electrons which passed the exit orifice of the chamber were discriminated with a 127o cylindrical energy selector coupled with an entrance set of electrostatic lenses and detected by a Faraday cup. Measuring the attenuation of intensity of the projectile-particle beam transmitted through the target volume, the absolute TCS for a given impact energy was derived from the Beer-Lambert law. The measurements were carried out for a given energy in a series of alt least 4 runs, each one taking at least 7 values and an averaging procedure was applied to derive the final total cross section at a particular energy. Besides the experimental measurements, we have additionally determined TCS using the Additivity Rule. We have also evaluated our experimental data using a fitting procedure with the Born-like formula containing two parameters for each gas. Our experimental data are in good agreement with the majority of previous measurements published in the literature. There are no previous reports of experimental electron scattering Total Cross Section C2H5OH in the literature.

Pełny tekst źródłaLa teoria sobre les històries de vida i l’ecologia de poblacions desenvolupen principis ecològics basats principalment en estudis realitzats en espècies terrestres, sovint sense tenir en compte les espècies marines. A través d’aquesta tesi preteníem descriure alguns dels processos i mecanismes que configuren la dinàmica poblacional de Cystoseira zosteroides, una macroalga longeva i formadora d’hàbitat, que habita en aigües profundes del Mediterrani Nord- Occidental. En un context més ampli, també es pretén augmentar la nostra comprensió actual sobre la dinàmica poblacional i la història de vida de les macroalgues. Els resultats obtinguts mostren que C. zosteroides presenta una dinàmica poblacional molt lenta. Mentre que altres poblacions de Fucals i de Kelps d’hàbitats de poca profunditat depenen principalment de processos reproductius i del creixement dels organismes, les poblacions naturals i no pertorbades de C. zosteroides es mantenen gràcies a l’elevada supervivència i la llarga esperança de vida dels individus adults. També demostrem que la capacitat de dispersió de les macroalgues brunes és molt limitada en comparació amb altres taxons, tot i que els Kelps presenten un major potencial de dispersió que les Fucals. Els nostres resultats també demostren que la denso-dependència juga un paper clau regulant la dinàmica poblacional de C. zosteroides, ja que pot impulsar la seva recuperació després de grans pertorbacions. A diferència de les poblacions no alterades, després de grans esdeveniments de mortalitat, la recuperació i dinàmica de les poblacions de C. zosteroides depèn molt dels processos reproductius. Això és especialment preocupant donada la limitada dispersió efectiva d’aquesta espècie. No obstant, tot i que els esdeveniments de mortalitat aïllats es poden compensar amb polsos de reclutament, les nostres simulacions demogràfiques demostren que l’efecte combinat dels pertorbacions físiques, com les tempestes i les xarxes de pesca abandonades, comprometen la viabilitat de les poblacions de C. zosteroides. A més, hem demostrat que l’escalfament té un gran impacte en les primeres etapes de vida d’aquesta espècie, fet que retarda la capacitat de recuperació de C. zosteroides i augmenta la seva vulnerabilitat a altres pertorbacions. En general, els nostres resultats no només contribueixen a comprendre millor la dinàmica poblacional de les macroalgues, sinó que també proporcionen noves idees per a la seva gestió eficaç. Amb aquesta tesi, es demostra el paper clau de l’ecologia de poblacions i la història de la vida en la comprensió de la dinàmica de les espècies i destaca com aquestes disciplines poden ajudar-nos a entendre millor el futur dels ecosistemes marins costaners.
