Resumen
Seismic resistance of many buildings in Turkey is insufficient. Strengthening using R/C infills requires huge construction work. Feasible, easy strengthening techniques are being studied in Structural Mechanics Laboratory of METU. In this project, it was aimed to develop an economical strengthening method. This method is based on addition of steel fibers and/or PP fibers in mortar and application of mortar on masonry wall. Project was sponsored by the Scientific and Technical Research Council of Turkey (TÜ
BiTAK). Physical properties of cement, aggregate, and mortar used in tests were determined by material tests. After performing flexural strength and compressive strength tests, optimum mortar was obtained. R/C frames strengthened by applying the mortar to brick infilled walls were tested under reversed cyclic loads. Before the frame tests, two series of panel tests were performed to correctly model strengthened infill walls and to gather information about behavior of walls under load. Totally 10 frame tests were done. 4 tests were done as reference tests, and other 6 were done as strengthened frame tests. In the analytical part of study, the plastered hollow brick infill wall strengthened by FRM was modeled as two separate compression struts. First strut was used to model the plastered hollow brick infill wall. Second strut was used to model the FRM. This technique is effective in improving seismic behavior by increasing strength, initial stiffness, energy dissipation, and ductility. Moreover, the method provides strengthening of the buildings without evacuating the structure.

Resumen
Located on one of the highly active seismic fault systems in the world, the building stock in Turkey is mainly composed of reinforced concrete frames with 4-5 stories. Due to design and construction deficiencies resulting from the use of unqualified personnel and insufficient supervision, many of these buildings lack lateral stiffness, ductility and strength. For many structures, there is a need to alleviate these deficiencies by means of some rehabilitation techniques prior to earthquakes. One approach also used very widely in Turkey is to fill some of the frame bays by cast-in-place R/C panels. The procedure appears to be very practical at first glance. It also appears to be very economical as far as the production of the panels is concerned. However, the production phase is slow, dirty, destructive and disruptive to occupants. Moreover, it requires relatively skilled personnel and special equipment. Therefore, the real life experience shows that the actual cost in practice is much higher when all other hidden costs are taken into account. The aim of this experimental study is to explore the potential of using infill walls made of custom shaped and high strength concrete blocks as a simpler and more practical alternative to cast-in-place R/C panels to increase the lateral load bearing capacity of frame structures. The effectiveness of FRCM (Fiber Reinforced Cementitous Matrix) system on damaged structures is also investigated in this study.

Resumen
Since the discovery in the early 1950's, frames have emerged as an important tool in signal processing, image processing, data compression and sampling theory etc. Today, powerful tools from operator theory and Banach space theory are being introduced to the study of frames producing deep results in frame theory. In recent years, many mathematicians generalized the frame theory from Hilbert spaces to Hilbert C*-modules and got significant results which enrich the theory of frames. Also there is growing evidence that Hilbert C*-modules theory and the theory of wavelets and frames are tightly related to each other in many aspects. Both research fields can benefit from achievements of the other field. Our purpose of this dissertation is to work on several basic problems on frames for Hilbert C*-modules. We first give a very useful characterization of modular frames which is easy to be applied. Using this characterization we investigate the modular frames from the operator theory point of view. A condition under which the removal of element from a frame in Hilbert C*-modules leaves a frame or a non-frame set is also given. In contrast to the Hilbert space situation, Riesz bases of Hilbert C*-modules may possess infinitely many alternative duals due to the existence of zero-divisors and not every dual of a Riesz basis is again a Riesz basis. We will present several such examples showing that the duals of Riesz bases in Hilbert $C^*$-modules are much different and more complicated than the Hilbert space cases. A complete characterization of all the dual sequences for a Riesz basis, and a necessary and sufficient condition for a dual sequence of a Riesz basis to be a Riesz basis are also given. In the case that the underlying C*-algebra is a commutative W*-algebra, we prove that the set of the Parseval frame generators for a unitary group can be parameterized by the set of all the unitary operators in the double commutant of the unitary group. Similar result holds for the set of all the general frame generators where the unitary operators are replaced by invertible and adjointable operators. Consequently, the set of all the Parseval frame generators is path-connected. We also prove the existence and uniqueness of the best Parseval multi-frame approximations for multi-frame generators of unitary groups on Hilbert C*-modules when the underlying C*-algebra is commutative. For the dilation results of frames we show that a complete Parseval frame vector for a unitary group on Hilbert C*-module can be dilated to a complete wandering vector. For any dual frame pair in Hilbert C*-modules, we prove that the pair are orthogonal compressions of a Riesz basis and its canonical dual basis for some larger Hilbert C*-module. For the perturbation of frames and Riesz bases in Hilbert C*-modules we prove that the Casazza-Christensen general perturbation theorem for frames in Hilbert spaces remains valid in Hilbert C*-modules. In the Hilbert space setting, under the same perturbation condition, the perturbation of any Riesz basis remains a Riesz basis. However, this no longer holds for Riesz bases in Hilbert C*-modules. We also give a complete characterization on all the Riesz bases for Hilbert C*-modules such that the perturbation (under Casazza-Christensen's perturbation condition) of a Riesz basis still remains a Riesz basis.

Resumen
Les proteines r b c c sont caracterisees par la presence, de l'aminoterminus au carboxyterminus, des trois motifs ring, boite b et coiled coil. Le doigt de zinc du type ring (c 3hc 4) fait partie des interactions intermoleculaires dans des complexes multiproteiques et pourrait jouer un role dans leur assemblage ou stabilisation. Il est aussi responsable, en collaboration avec la boite b, de la localisation compartementalisee subcellulaire des proteines. Le doigt de zinc du type boite b (chc 3 - 4h 2) est implique dans des interactions proteine-proteines, par exemple dans la liaison de pml a rb1. Le domaine de dimerisation par helices hydrophobes (coiled coil) est une super-helice des helices et participe a la dimerisation, ensemble avec la boite b : le coiled coil comme surface d'interaction, la boite b peut-etre comme stabilisateur de l'orientation du coiled coil. Les trois domaines constituent le motif tripartie qui semble jouer un role fondamental dans l'adressage ou l'assemblage des macromolecules. Les membres les mieux etudies de cette famille multiproteique sont pml et les tif1. Pml est une proteine avec des capacites multiples de regulation : elle fait partie des complexes transcriptionnellement actifs, elle reprime (a travers l'apoptose) la croissance et la transformation, et elle controle des fonctions immunitaires, sous influence de l'acide retinoique et des interferons. Nous avons pu eclaircir le mecanisme moleculaire de l'induction transcriptionnelle de pml par les interferons avec l'identification d'elements fonctionnels de reponse aux interferons dans le promoteur de pml. Pml est fusionne au recepteur de l'acide retinoique, rar dans la translocation t(15 ; 17) specifiquement rencontree dans la vaste majorite

Resumen
This thesis presents a comprehensive study of long-span cold-formed steel single C-section portal frames. The study includes the formulation of a nonlinear beam finite element for thin-walled sections, a series of full-scale frame tests and component tests, finite element modelling and advanced analysis followed by the formulation of design guidelines. The study was aimed at exploring the structural behaviour through experiment and numerical analysis towards developing provisions for the design of cold-formed steel portal frames using Advanced Analysis. A nonlinear thin-walled beam element for general open cross-sections was formulated, incorporating warping effect and non-coincident location of the shear centre and the centroid. It was successfully implemented in the geometric nonlinear analysis framework of the OpenSees finite element software. Towards investigating the behaviour and determining the ultimate strength, six full-scale tests on cold-formed steel single C-section portal frames were conducted. Separate tests were performed on frame connections, point-fastener connections and coupons to obtain the material parameters required for numerical modelling. Advanced shell finite element models of the full-scale frames and frame connections were created and validated against experimental results. The bolts and screws used for the connections between components were represented by point-based deformable fasteners. The force-deformation characteristics of the deformable fasteners were incorporated and successfully implemented in the Advanced Analysis. The strength of cold-formed steel single C-section portal frames determined by the Direct Strength Method and the Direct Design Method were compared. To account for inherent uncertainties in the strength of CFS portal frames, system resistance factors were derived. It was concluded that the Direct Design Method using Advanced Analysis is the likely future method for the design of cold-formed steel portal frames.

Dans cette thèse, on considère M, une sous-variété C R de CN, passant par 0 et on donne des conditions suffisantes, liées à la forme de Levi en 0, pour que toutes fonction C R sur ω, un voisinage ouvert de 0 dans M, soit la restriction à ω d’une fonction holomorphe au voisinage de 0 dans CN. La méthode utilisée consiste en la construction de disques analytiques dont le bord est sur M et qui contiennent un voisinage de 0 dans CN, d’abord dans un cas modèle puis dans la cas général par approximations
In this thesis, we consider M, a CR submanifold of ₵N, which passes through 0, and, we give sufficient conditions, related to the Levi form at the origin, so that each C R function on ω, an open neighborhood of 0 in M, is the restriction to ω of a holomorphic function defined on an open neighborhood of 0 in ₵N. The method used is to construct analytic discs whose boundaries lie on M and which contain a neighborhood of 0 in ₵N, first in a model case, then in the general case by approximations

AbstractRuthenium-Catalyzed C-C Bond Formation via Functional-Group Directed C-H Bond ActivationXiangyu GuoAdvisor: Prof. Chao-Jun LiMcGill UniversityThis thesis is an investigation on the formation of carbon-carbon (C-C) bonds in the presence of ruthenium catalyst.In the first part of this thesis, oxidative dehydrogenative coupling reactions for carbon-carbon (C-C) bond formation are described. A ruthenium-catalyzed dimerization of 2-phenylpyridine derivatives is demonstrated to synthesize biaryls using iron(III) chloride as the terminal oxidant. In addition, the oxidative cross coupling of arenes and cycloalkanes is also illustrated, achieving a unique para-selectivity.In the second part of the thesis, a ruthenium-catalyzed olefination via decarbonylative addition of aldehydes to terminal alkynes is described. Conjugated and isolated C=C bonds can be chemoselectively generated in two catalytic systems starting from aromatic and aliphatic aldehydes. The method provides an alternative synthesis of C=C bonds from direct C-H bond addition to triple bonds.

Resumen
This thesis describes the formation of new C-C bonds from the direct oxidative coupling of two C-H bonds, through the use of metal catalysts for activation. First, three different oxidative Cross-Dehydrogenative-Coupling (CDC) reactions will be presented. Initially, through the use of an organic co-catalyst, N-hydroxyphthalimide (NHPI), oxygen could be utilized as the terminal oxidant for the metal catalyzed alkylation of benzylic C-H bonds with 1,3-dicarbonyls and ketones in Chapter 2. The reaction was found to be feasible for a variety of substrates with readily enolizable C-H bonds. Next, the 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) mediated alkynylation of sp3 C-H bonds was studied. A novel copper (I) triflate catalyzed CDC reaction of unactivated benzylic C-H bonds and terminal aromatic alkynes is presented in Chapter 3. After further studies, the alkynylation of benzylic ethers could also be realized in the presence of a catalytic amount of silver (I) triflate, as described in Chapter 4. Both procedures were found to be amendable for aromatic terminal alkynes, however could not be extended to aliphatic alkynes. Finally, a palladium catalyzed Minisci-type reaction will be described in Chapter 6. Peroxide generated α-hydroxyalkyl radicals could be reacted with azines in moderate to good yields. A stoichiometric amount of acid, used in the traditional Minisci reaction, was replaced by a catalytic amount of palladium dichloride.
Cette thèse décrit la formation de nouvelles liaisons C-C par activation oxydative directe de deux liaisons C-H grâce à l'utilisation de métaux de transition comme catalyseurs. La première partie présentera trois différentes réactions de Cross-Dehydrogenative-Coupling (CDC) oxydantes. Dans un premier temps, sera présentée dans le chapitre 2, la réaction d'alkylation de liens C-H benzylique par 1,3-dicarbonyles et cétones. Ce system a démontré son efficacité sur une large variété de substrats contenant des liaisons C-H enolysable. De plus il a été rendu possible, grâce à l'utilisation d'un co-catalyseur organique, le N-Hydroxyphthalimide (NHPI), d'utiliser l'oxygène moléculaire comme oxydant terminal. Dans un second temps, nous étudierons l'utilisation du 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) comme médiateur pour l'alkynylation de liaisons sp3 C-H. Une nouvelle CDC réaction catalysée par le triflate de cuivre (I) sera présentée dans le chapitre 3, entre un alcyne et une liaison C-H benzylique. Le chapitre 4 présentera le développement de cette réaction à l'alcynation d'éthers benzyliques en présence d'une quantité catalytique de triflate d'argent (I). Ces deux procédures sont seulement applicables pour les alcynes vrais aromatiques. Finalement, le chapitre 6 portera sur la réaction de Minisci catalysée par le palladium. Le peroxyde radical α-hydroxyalkyl généré lors de la réaction est capable de réagir avec les azines. La quantité stœchiométrique d'acide nécessaire lors de la traditionnelle réaction de Minisci, a été remplacée par une quantité catalytique de dichloro palladium.

Resumen
La petite ville s'est transformée au point que seuls les anciens s'en souviennent encore et narrent une ville qui désormais a disparu. Le plus remarquable est la séparation du politique et du système d'intégration à la ville désormais ouvert au système marchand. L'unité de la ville s'efface alors au profit de la qualité de séparation. Dans ce contexte, l'habitant en tant que statut disparaît au profit de l'habitant qualité qui s'acquiert. La petite ville n'est plus qu'un "habit vide" et les relations entre les individus s'effectuent ailleurs. Plus précisément, à partir d'un "archipel pavillonnaire" et donc dans des îlots séparés et différenciés socialement. Nous argumentons donc pour une séparation des univers sociaux à l'instar des territoires urbains et plus précisément des villes américaines. Les habitants vivent dans des groupes sociaux inclusifs organisés sur une base spatiale. L'archipel pavillonnaire est alors un monde de la complexité dans lequel l'individualisation et la séparation en formulent l'expérience. En définitive, dans l'archipel pavillonnaire, la qualité de séparation, la faiblesse des liens et l'évitement des conflits constituent un ordre moral singulier : le minimalisme moral
The little town has changed so much that only the elderly can remember it and tell the story of bygone days. What is worth noting is the separation between politics, and the town system of integration now open to free trade. The town unity is replaced by the quality of separation. In these circumstances, the inhabitant as status steps aside in favor of the inhabitant as quality, which can be acquired. The small town is merely an empty garment and the relationships between inhabitant are elsewhere, more precisely from a residential area in socially separate places. We therefore advocate for a separation of social universes following the example of urban territories and more precisely American cities. The inhabitant live in inclusive social groups organized on a spatial basis. The suburban area is then a world of complexity in which individualization and separation express this experience. In other words, in the suburban area, the quality of separation, the weak ties and the avoidance of conflicts compose a peculiar moral order : the moral minimalism

Resumen
This thesis provides a cultural history of anatomy in Enlightenment France (c. 1700-c.1795). It tells the overlapping stories of the rise of anatomy as a public, polite, and sociable science experienced by gentlemanly amateurs and of anatomy's consolidation as a dynamic experimental branch of natural history. The first narrative explores how eighteenth-century anatomy gained amateur adherents through textbooks, three-dimensional objects, spectacular courses, and tutors. The second offers an account of how anatomists transformed their field into a viable, utilitarian, and socially useful research discipline. This project makes contributions to the histories of science, Old Regime France, and gender, and the social history of medicine. It shows how Enlightenment anatomy enlisted a distinctive set of places, objects, and peoples. First, anatomy was produced, packaged, and disseminated to consumer audiences in traditional scholarly and pedagogical spaces, but also outside them, in venues of learning that included the court, commercial districts, museums, public spaces, private chambers, amphitheatres, and cabinets. Second, anatomical knowledge was created, conveyed, and ratified in these settings using familiar materials like corpses, as well innovative artificial materials like wax, wicker, glass, and textiles. The material culture of anatomy was inscribed in the worlds of amateur appreciation and experimental practice, where tourism played an important role in the exchange of goods and know-how. Finally, those who practised anatomy and the public which digested it achieved new recognition during this period and collectively contributed to shaping the form and content of anatomical knowledge. The result was that eighteenth-century anatomy accommodated a broader range of individuals – men and women, amateurs, medical practitioners, artists, and artisans – than ever before.
Cette thèse examine l'histoire culturelle de la science anatomique dans la France au siècle des Lumières (c.1700-c.1795). En adoptant une approche culturelle, elle étudie à la fois l'émergence de l'anatomie comme science liée à la mondanité, pratiquée par des amateurs appartenant à l'élite, ainsi que la formalisation de la discipline anatomique en tant que domaine expérimental de l'histoire naturelle. En premier lieu, cette thèse explore comment l'anatomie, à l'aide de manuels, d'objets tridimensionnels, de leçons publiques et de tuteurs, a attiré des disciples amateurs. En second lieu, elle démontre comment les anatomistes ont transformé leur champ en une discipline scientifique viable et utile pour leur société. Cette double analyse contribue donc à l'histoire des sciences, de la France d'Ancien Régime, du genre, ainsi qu'à une histoire sociale de la médecine. Cette thèse tente de démontrer comment la discipline anatomique telle que pratiquée au cours des Lumières réunissait un ensemble distinct de pratiques, d'objets et de personnes. D'abord, le savoir anatomique était produit, accumulé et disséminé au public dans des espaces pédagogiques et académiques traditionnels mais également, au-delà de ceux-ci, dans des espaces d'apprentissage plus larges qui incluaient la cour, des musées, des espaces commerciaux, des espaces publics tout comme des chambres privées ainsi que des amphithéâtres et des cabinets. Ensuite, le savoir anatomique était créé, transmis et confirmé dans ces espaces en utilisant des matériaux familiers tels que des corps, mais aussi des matériaux artificiels novateurs tels que la cire, l'osier, le verre et les textiles. Ainsi, la culture matérielle de la science anatomique s'est inscrite en lien avec la culture amateur de l'appréciation et la pratique expérimentale, où le tourisme jouait un rôle important pour l'échange d'objets et de savoirs. Finalement, les anatomistes, et leur public, ont acquis un nouveau degré de reconnaissance au cours du siècle des Lumières et ont, ensemble, contribué au développement du savoir anatomique tant au niveau de la forme que du contenu. Ces transformations ont permis à un plus grand nombre d'individus d'origines diverses – hommes, femmes, amateurs, médecins, artistes, artisans – de se familiariser avec l'anatomie.

Texto completo
Resumen
This study considers the mixed economy for medical services in Herefordshire between 1770 and 1850. Medical services were an integral part of wider systems of welfare and were provided within a mixed economy that included private practice, state provision, philanthropic activities and mutual societies. Significant resources were spent within the sector and influence over their deployment was of direct interest to parishes, the municipal council, magistrates, philanthropists and individual members of the elite. Four types of medical services are reviewed. These are the provision of personal care by medical practitioners in the private, public and charitable sectors, the establishment of Hereford General Infirmary, changes in institutional services for the insane and developments in public health. Two underlying themes are discussed throughout the thesis. The first of these is the complexity of the mixed economy for medical services. Important changes over the period are identified and the interrelationships between the various sectors investigated. The dominance of public, private or charitable provision shifted in the period as a result of both national and local factors. The second theme explored is the interplay between politics and the systems and institutions providing medical services. The importance of political considerations in shaping local policy towards medical services is demonstrated through detailed case studies. These include examining the link between the launch of the subscription appeal for Hereford Infirmary and the parliamentary election campaign in 1774, approaches taken towards the management of the cholera epidemic of 1832 and the campaign to establish a public lunatic asylum in the late 1830s.

Resumen
This dissertation examines Scottish involvement in the Hudson's Bay Company (HBC), c.1779 to c.1821. It surveys the Company's recruitment practices, and the national and regional contribution of Scots to the HBC, demonstrating that Orkneymen were disproportionately numerous throughout the entire period under examination. This study explores their motivation for entry to the HBC, and the various routes (and obstacles) to advancement of salary and station. It also seeks to establish whether Scottish networks operated in the fur trade, and the utility of such connections. Although Scots encountered many opportunities for betterment in Rupert's Land, they were also confronted with the challenge of working in a commercially competitive and remote wilderness environment. Extreme climatic conditions, insufficient food/medicinal supplies, laborious work duties, and violent trade rivalry meant that illness, disability, and death were common occurrences. The extent to which the paternalistic directors endeavoured to mitigate such hardships, and tended to the welfare of employees and their dependents, is assessed. Finally, the social, cultural and economic impact of Scots on both their temporary and home residences is explored. This discussion includes the significance of 'Scottishness' in the fur trade and the importance of 'home' to temporary migrants. In addition, this study highlights the difficulties of remitting savings and domestic support money to dependents in Scotland, and the successes of employees who fulfilled their personal ambitions on their return to Orkney, and climbed onto the property ladder.

On considere un espace symetrique semi-simple g/h ou g est un groupe de lie semi-simple complexe et h une forme reelle de g. On etudie les fonctions h-invariantes sur g/h qui sont solutions propres des operateurs differentiels g-invariants sur g/h. De telles fonctions sont dites spheriques. Dans la premiere partie, nous montrons qu'une fonction generalisee spherique sur un ouvert h-invariant v de g/h est une fonction localement integrable sur v et analytique sur l'ensemble des points reguliers de v. Nous donnons egalement des conditions suffisantes pour qu'une fonction h-invariante et localement integrable sur g/h soit spherique. Dans la deuxieme partie, on suppose que l'algebre de lie h de h admet une sous-algebre de cartan compacte t. On note t le sous-ensemble de cartan associe a t. On montre qu'une fonction generalisee spherique sur g/h est determinee par sa restriction a t. Ensuite, a partir d'une fonction generalisee h-invariante et temperee f sur h qui est solution propre des operateurs differentiels h-invariants a coefficients constants sur h, on construit une fonction generalisee spherique f' sur g/h. Lorsque la fonction f est la transformee de fourier de l'orbite d'un element regulier elliptique du dual de h sous l'action de la representation coadjointe de h, on obtient une serie continue de fonctions generalisees spheriques sur g/h. Sur un exemple, on montre comment cette serie continue intervient dans la formule d'inversion pour g/h. Ceci donne un lien entre l'analyse harmonique sur g/h et la methode des orbites

Diaphragmatic myotubes are known to constitutively express CCR1, a chemokine receptor in the C-C chemokine family, when cultured in vitro. It has been shown that CCR1 and its ligand CCL3 (MIP-1α) are directly involved in muscle repair responses in vitro. Furthermore, in vivo experiments, carried out in the MDX mouse model of muscular dystrophy, showed that these molecules were up-regulated in the dystrophic diaphragm muscle thus suggesting a role for CCR1 in inflammation and muscle healing. In this study, indeed, the role of CCR1 was investigated, with focus on inflammatory cell infiltration within the injured muscle using the freeze injury murine model. This study suggested that there is no significant difference in muscle regeneration or infiltration between CCR1-/- mice and their wild-type controls. There was also no difference in the muscle force between the knockout and their controls at 3, 7, and 14 days post injury. Investigation of individual infiltrating cell (macrophage, CD4 T-cells, CD8 T-cells) populations in the injured tissue yielded no significant difference. These data suggest that, although CCR1 has been found to play a role in myoblast proliferation and migration in vitro, it does not seem to have any apparent effect on muscle regeneration in vivo in the context of the freeze-injury model.
In vitro, les myotubes diaphragmatiques expriment de façon constitutive CCR1, le récepteur de la famille des chemokines C-C. Il a été démontré que CCR1 et son ligand, CCL3 (MIP-1α), sont directement impliqués dans le processus de la réparation musculaire in vitro. De plus, des études in vivo dans la souris MDX ont démontré que l'expression de ces molécules augmente dans le diaphragme dystrophique. Ceci suggère un rôle pour CCR1 dans l'inflammation et la réparation musculaire. Dans cette étude, le rôle de CCR1 a été étudié avec un focus sur l'infiltration des cellules dans le muscle blessé suite à une blessure par congélation dans le modèle animal. Cette étude suggère qu'il n'y a aucune différence dans la réparation musculaire et l'infiltration cellulaire entre la souris CCR1 -/- et le contrôle. De plus, il n'y a aucune différence significative dans la force musculaire entre ces deux modèles à 3,7 et 14 jours suite à la blessure. L'étude individuelle des populations cellulaires (macrophages, cellules T CD4+ et CD8+) n'a montré aucune différence significative. Nos résultats suggèrent que malgré le rôle de CCR1 dans la prolifération et la migration de myoblastes in vitro, CCR1 n'est pas implique dans cette régénération post-traumatique in vivo.

Resumen
This thesis provides a detailed examination of the impact of James VII, both as Duke of York and King, on Scottish politics between c. 1679 and c. 1686. This start date has been chosen because, as a result of the Exclusion Crisis in England, Charles II sent his brother and heir, James, Duke of York, to Scotland in November 1679. The thesis ends with a thorough investigation of the final session of James VII's Scottish Parliament, in which his notion of toleration for Roman Catholics was rejected as unpalatable. Between c. 1679 and c. 1686, James had a managerial role over the government of Scotland, not least of all as a result of his prolonged residence in Edinburgh which lasted, with the exception of a seven month period back in England, from November 1679 until March 1682. In the subsequent years James remained closely involved with the government of Scotland largely as a result of the political reshuffle he oversaw immediately prior to his final departure. The themes examined in this thesis include the role of James in relation to a number of significant Scottish political concerns. These include the militia and Highland policies, as well as the enforcement of the 1681 Test Act and pacification of disorder, particularly from the remnant Covenanters. The 1681 Parliament, in which James was High Commissioner, is analysed in detail, as are the1685 and 1686 sessions of the Parliament James held as King. The threat posed by the 1685 Argyll rebellion is also investigated, as is the political factionalism of the period. A substantial amount of primary and secondary sources have been used during the research for this thesis. The primary material includes both printed and manuscript sources, much of which has been previously neglected. This includes contemporary pamphlet literature and correspondence, as well as Supplementary Parliamentary Papers.

Resumen
Une approche comparée des fiscalités internes dans le CARIMON permet de mettre en évidence des différences en matière d'impôt sur les bénéfices des entreprises, et une disparité des techniques d'imposition de la dépense. Elle suggère également d'étendre la coordination des politiques fiscales des pays membres au-delà de l7accord sur l'harmonisation des incitations à l'investissement dans l'industrie. L'appartenance des états de la région à la catégorie des pays en développement les autorise à revendiquer, dans le cadre des conventions fiscales internationales conclues avec les pays exportateurs de capitaux et de connaissances, un large pouvoir d'imposition pour l'état de la source des revenus, afin de sauvegarder leurs intérêts financiers. L'importance des courants d'échanges entre la Caraïbe et les États-Unis d'Amérique impose aux pays du CARICOM de s'attacher à définir une position commune à l'égard de la politique fiscale américaine dans la région. Dans l'ordre communautaire, la convention fiscale entre les pays plus développés d'une part, et les pays moins développés d'autre part, et la mise en place de tels traités au niveau sous-régional doivent tenir compte de la situation des pays les moins avancés économiquement, et favoriser la fluidité des échanges dans le marché commun
A comparative approach of inland taxation in CARICOM allows to emphasize the differences as regards tax on profts, and disparition in sales taxes. This approach also suggests the extension of coordination of fiscal policies of member states beyond the agreement on harmonization of fiscal incentives to industry. The states of the region that belong to the category of developing countries, may claim, in the scope of double taxation agreement with capitals and knowledges exporting countries, a large power to tax for the contracting state in wich the incomes are produced. The importance of exchanges between the Caribbean and United States of America induice the CARICOM countries to adopt a common position concerning the American fiscal policy in this region. In the sphere of the community, the double taxation agreement between more developed countries on the one hand less developed countries on the other hand, and the setting up of such treaties at a subregional level must take into account the situation of less developed countries, and favour the flows of exchanges in the common market

Texto completo
Resumen
We consider various geometrical and physical aspects of the r-map and c-map, which are two maps induced by the dimensional reduction of 5d and 4d, N = 2 supergravity coupled to vector multiplets respectively. We treat reduction over a spacelike or timelike dimension on an equal footing, and prove, for the first time, that the target manifold in the image of the timelike c-map is para-quaternion Kahler. In order to do this we provide a new formulation of projective special Kahler geometry based on real Darboux coordinates, which is useful both mathematically and physically in its own right. As an application we investigate how the r-map and c-map can be used to generate new stationary black hole solutions. In four dimensions we construct new extremal non-BPS solutions, and in both four and five dimensions we construct new non-extremal solutions. We also take the first steps towards constructing new rotating solutions, though at this stage we only recover known solutions. The systematic and geometrical nature of these constructions allows us to gain a deeper understanding of many familiar properties of black holes in supergravity, such as the attractor mechanism and the transformation of BPS into non-BPS black holes using a field rotation matrix. We also observe an interesting and novel feature relating to non-extremal black holes: in order for solutions to correspond to non-extremal black holes with finite scalar fields we find that the number of integration constants must reduce by half. This suggests that non-extremal black holes always satisfy first order equations similar to their extremal counterparts. For STU-like models all calculations are performed explicitly.

Resumen
This thesis is a part of the Local Hawk student project where the overall goal is to develop a Autonomous Unmanned Aerial Vehicle (AUAV). The project was initiated by Kongsberg Defence Systems (KDS) and is developed in collaboration with the Norwegian University of Science and Technology (NTNU). In an AUAV it is necessary to have a guidance system in order to be autonomous. To be able to test guidance principles in practice without risking the Local Hawk airframe the need of a ground based test platform became apparent. This thesis is the development of the Local Bug Test Platform.The Local Bug is based on a R/C car and utilizes electronics used and developed in the Local Hawk project. In order to understand the system behaviour, vehicle modelling is discussed and two models are presented. One of them is used in a SIMULINK simulator design for the Local Bug. The simulator is used to ensure the correct controller behaviour before it is tested on the real system. Phoenix II is the backbone of the Local Bug electronics and is used to gather measurement data, log data to memory and execute controller algorithms. Custom made C-code is used as a framework providing all the functionality needed. A introduction to Real-Time Workshop is given, and a step-by-step guide on how to use RTW generated C-code on the Phoenix II for controller purposes.A heading controller is designed and used in combination to two different guidance algorithms. The Line of Sight algorithm aims for the next waypoint regardless where the vehicle is positioned relative other waypoints. A Cross-Track Error algorithm with look ahead distance functionality focuses on minimizing the vehicles distance from a desired path. Both algorithms successfully guides the vehicle trough the test route visiting all the waypoints. The Local Bug is now usable as a test platform for controller algorithms. Measurements are logged to memory making it possible to analyse the performance after a test has been conducted. The overall functionality is found to be satisfactory and the Local Hawk project now has its desired controller/guidance test platform.

Resumen
The research described here focuses on the molecular variations, clinical significance and structural interactions of the innate immune protein, C-reactive protein (CRP). Monomeric CRP (mCRP) was produced through urea-induced dissociation, at an optimum concentration of 3M urea over a 10-week period. Dissociated samples were purified via size exclusion chromatography and confirmation was provided via Western Blot analysis. In contrast with previous published works, this mCRP retained the ability to reversibly bind to phosphocholine. Furthermore, the binding of mCRP with cell wall polysaccharide does not result in the generic precipitation trend as that seen with pentameric CRP (pCRP). Human serum samples with raised CRP levels ( > 100mg/L) were analysed (n =40) to determine whether circulating mCRP could be detected in vivo. All 40 samples tested positive for pCRP via Western Blot and ELISA analysis, with further quantification via the UV Spectrophotometer supporting the calculated pCRP levels. Monomeric CRP was identified in all the 40 patient samples tested, with an average value recorded of 0.88mg/L (SE = ±0.142). Informed by the results from in vitro mCRP studies, the mCRP displayed a molecular weight of approximately 25kDa based on size exclusion chromatography and Western Blot analysis and demonstrated an ability to reversibly bind phosphocholine. To our knowledge, we are the first to successfully purify and identify a monomeric form of CRP from human serum through these procedures. Crystallisation trials of in vitro produced mCRP and the complex of pCRP with C1qGHR and CWPS did not result in the growth of any protein crystals of sufficient diffraction quality. One crystal from the complex crystallisation trials diffracted to 9Å with follow up conditions currently being pursued. Furthermore, additional crystallisation trials from both experiments have generated potential conditions which may be refined in future research to produce high-quality diffraction grade crystals.

Resumen
This thesis is the first systematic examination of the textual and material evidence for diseaseand hunger in Carolingian and early Ottonian Europe, c.750 to c.950 CE. It draws upon medieval textual records including annals, capitularies, chronicles, concilia, correspondence, histories, gesta, poetry, polyptychs, secular biographies, and vitae, as well as numerous modern archaeological, palaeobotanical, palaeoclimatic, palaeomicrobiological and palaeopathological reports in order to comment on epidemics, epizootics, food shortages and the baseline or current of non-pestilential disease and chronic hunger underlying them. It first surveys the historical and scientific scholarship on these phenomena and the methodologies intrinsic to their study. The evidence for non-pestilential and chronic hunger is then addressed, before pestilences and food shortages are identified in time and space. We can discern roughly thirty-two peacetime epidemics, ten epizootics, ten famines and twelve lesser shortages. A short investigation of the impact of, and response to, disease and hunger in Carolingian and early Ottonian Europe is presented in conclusion. The thesis demonstrates that disease and hunger, in both endemic and epidemic forms, were common realities for mid eighth- through mid tenth-century continental European populations, and argues that epidemics, epizootics and subsistence crises had major, short-lived but possibly cumulative, repercussions for Carolingian and early Ottonian demographic and, consequently, economic growth, in addition to intensifying the impact of the silent toll of the baseline of non-pestilential disease and chronic hunger. The textual evidence addressed in the thesis is presented in Latin and English in three appendices.
Cette thèse est le premier examen systématique des sources textuelles et matérielles concernant la maladie et la faim en Europe carolingienne et ottonienne, entre le milieu du VIIIe et le milieu du Xe siècle. Elle s'appuie sur des sources textuelles, comprenant des annales, capitulaires, chroniques, actes de conciles, la littérature épistolaire, les oeuvres historiques, les gesta, la poésie, les polyptyques, biographies laïques et vies de saints, ainsi que de nombreux rapports archéologiques, paléobotaniques, paléoclimatiques, paléomicrobiologiques et paléopathologiques récents afin d'expliquer les épidémies, épizooties et pénuries alimentaires, de même que le problème fondamental de la faim, qu'elle soit la conséquence de maladies non-pestilentielles ou de maladies chroniques sous-jacentes. Elle passe en revue l'historiographie et l'état des recherches scientifiques sur ces phénomènes ainsi que la méthodologie qui sert à leur étude. Les indications concernant la faim non pestilentielle et chronique sont alors analysées, ensuite celles concernant les pestes et les pénuries alimentaires, qui sont identifiées dans le temps et l'espace. Nous pouvons discerner assez bien trente-deux épidémies en temps de paix, une dizaine d'épizooties, dix famines et dix à douze pénuries moindres. La conclusion présente une enquête bref sur l'impact de la maladie et de la faim et la réponse qu'elles ont suscitées en Europe carolingienne et ottonienne. La thèse démontre que la maladie et la faim, dans ses formes endémique autant qu'épidémique, étaient des réalités courantes pour les populations européennes continentales entre le milieu du VIIIe et le milieu du Xe siècle et défend l'idée selon laquelle les épidémies, les épizooties et les crises de subsistance ont été majeures, de courte durée mais dont l'effet a pu être cumulatif. Leurs répercussions sur la démographie de l'Europe carolingienne et ottonienne et, par conséquent, sur la croissance économique ont intensifié l'impact déjà dévastateur des maladies non pestilentielles et de la faim chronique. Les indications tirées des sources écrites utilisées dans la thèse sont présentées en latin et en traduction anglaise dans trois annexes.

Resumen
Chemical vapour deposition on copper is an effective way to synthesize large scale, high quality graphene monolayers. One of the factors limiting the mechanical strength and electronic properties of CVD graphene is the size of crystal domains and the presence of grain boundaries. We investigated the effects of varying growth conditions and found that decreasing methane flow and pressure led to lower graphene nucleation density and larger grain size.Strain engineering presents an opportunity to tune the electronic properties of graphene. We investigated strain in graphene on copper by Raman spectroscopy and found an upshift in the position of the 2D Raman peak with increasing CVD growth temperature. We showed that it is possible to tune the amount of compressive strain in graphene on copper by modifying the CVD growth temperature and that this leads to a shift in Fermi energy and Fermi velocity. We synthesized graphene monolayers comprised of both C-12 and C-13 carbon atoms. Several combination Raman modes were investigated and the D+D′ peak was shown to be the result of an intervalley + intravalley scattering process. Using the isotope dependent shift in Raman spectrum and the presence of strong double resonance partners for several peaks we were able to accurately determine the position of multiple Raman lines. A combination of three different laser energies allowed us to determine the dispersion of these Raman lines and map out an experimental phonon band structure for graphene.
La dépôt chimique en phase vapeur (CVD) sur le cuivre est un moyen efficace pour faire la synthèse à grande échelle de monocouches de graphène de haute qualité. L'un des facteurs limitant les propriétés mécaniques et électroniques du graphène CVD est la taille des domaines cristallins et la présence de joints de grains. Nous avons étudié les effets de la variation des conditions de croissance et constaté que la diminution de débit et de pression de méthane mène à une reduction de la densité de nucléation du graphène et à de plus grands grains. L'ingénierie de la tension offre la possibilité d'ajuster les propriétés électroniques du graphène. Nous avons étudié la tension dans le graphène sur cuivre par spectroscopie Raman et constaté un déplacement positif du pic Raman 2D avec l'augmentation de la température de croissance CVD. Nous avons montré qu'il est possible d'ajuster la quantité de compression dans le graphène sur le cuivre en modifiant la température de croissance CVD et que cela mène à un changement dans l'énergie de Fermi et la vitesse de Fermi.Nous avons synthétisé des monocouches de graphène composées d'atomes de carbone C-12 et C-13. Plusieurs modes de combinaison Raman ont été étudiés et nous avons demontré que le pic D + D′ est le résultat d'un processus de diffusion intervallée + intravallée. En exploitant la dépendance du spectre Raman sur l'isotope de carbone et la présence de partenaires de double résonance pour plusieurs pics nous avons pu déterminer avec précision la position de plusieurs lignes Raman. Une combinaison de trois énergies laser différentes nous a permis de déterminer la dispersion de ces lignes Raman et de reconstruire de manière expérimentale une structure de bande de phonon pour le graphène.

Resumen
Phospholipases C (PLCs) are a large family of enzymes that regulate the cleavage of phosphatidylinositol-4,5- bisphosphate into Inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG). This project included research on PLCζ and PLCβ1 on male infertility and thyroid cancer respectively. Human PLCζ (hPLCζ) is the key protein for egg activation following sperm-egg fusion and triggers the release of Ca2+ producing a series of oscillations which initiate embryogenesis. Defects in hPLCζ lead to infertility, thus the project aimed at its expression and enrichment suitable for biomedical applications. The results included 1) Comparison of hPLCζ bacterial expression from twenty four plasmid constructs with varying protein tags. 2) Expression of active soluble hPLCζ, free from its bacterial solubility partners. The PLCβ1 project involved a novel InDel (1076 bp deletion, ATAA junction insertion) identified in the 3rd intron of PLCβ1 (Chr 20) by genome-wide linkage analysis (GWLA, LOD score 3.01) of a large kindred with multinodular goitre (MNG) progressing to papillary thyroid cancer (PTC). Affected individuals exhibited increased PLCβ1 transcript levels in their thyroids and the InDel has a putative ERα binding site. The project aimed to, 1) Develop a genotyping technique for high-throughput PLCβ1 InDel screening in large cohorts 2) Determine the InDel’s mechanism of action in modifying thyrocyte proliferation. 3) Next generation sequencing (NGS) of the chr20 region identified by GWLA to identify potential variants responsible for MNG. 1) A QPCR genotyping method was established and the InDel identified in patients with benign thyroid disease. 2) Reporter gene assays suggested silencer elements within the InDel. 3) PLCβ1 knockdown using siRNA exhibited a trend in inhibiting proliferation of a thyroid cell-line. 4) NGS of the 20cM-Chr20 GWLA identified region found no additional disease loci confirming a role for the PLCβ1 InDel. The InDel provides a biomarker for MNG patients most likely to develop PTC.

Resumen
Structural evaluation and seismic vulnerability assessment of Reinforced Concrete (R/C) buildings have especially become the focus of many researches in Turkey and abroad especially after the August 17, 1999 earthquake causing major life and property losses. A devastating earthquake being expected in Istanbul-Marmara region raises many questions on how well the existing buildings are constructed and whether they can stand a major earthquake. Evaluation of existing buildings for seismic vulnerability requires time consuming input preparation (pre-processing), modelling, and post processing of analysis results. The objective of the study is to perform automated seismic vulnerability assessment of existing R/C buildings automatically over the internet by asking internet users to enter their building related data, and streamlining the modelling-analysis-reporting phases by intelligent programming. The internet based assessment tool is prepared for two levels of complexity: (a) the detailed level targets to carry out seismic evaluation of the buildings using a linear structural analysis software developed for this study
(b) the simplified level produces seismic evaluation index for buildings, based on simple and easy to enter general building information which can be entered by any person capable of using an internet browser. Detailed level evaluation program includes a user friendly interface between the internet user and analysis software, which will enable data entry, database management, and online evaluation/reporting of R/C buildings. Building data entered by numerous users over the internet will also enable formation of an extensive database of buildings located all around Turkey. 36 buildings from Dü
zce damage database, generated by the cooperation of Scientific and Research Council of Turkey (TÜ
BiTAK) and Structural Engineering Research Unit (SERU) after the 17 August 1999 Kocaeli and the 12 November 1999 Dü
zce earthquakes, are used in the analyses to identify relationship between calculated indices and observed damage levels of buildings, which will enable prediction of building damage levels for future earthquakes. The research is funded by Science Research Program (BAP 2003-03-03-03), NATO-SfP 977231, and TUBITAK ICTAG-I574 projects. The contribution of the research is composed of a) online building index -performance analysis/evaluation software which might be used by any average internet user, b) an ever-growing R/C building database entered by various internet users.

Resumen
Mestrado em Engenharia Civil
A avaliação da vulnerabilidade e o reforço de edifícios existentes de betão armado, nomeadamente face à sua segurança à ação sísmica, é um tópico de elevada importância e premência, tal como comprovado nos recentes sismos ocorridos por todo mundo, e particularmente em países do sul da Europa. Assim, reconhece-se que deve dar-se atenção à investigação na área da análise e reforço das construções existentes. Algumas soluções arquitetónicas adotadas até aos anos 70, combinadas com a prática naquele período do projeto estrutural, e particularmente no simplificado ou inexistente cálculo sísmico, fizeram com que muitas dessas estruturas tenham associada uma vulnerabilidade elevada, podendo sofrer danos consideráveis se solicitadas por um sismo. O objetivo deste trabalho é o estudo de várias soluções de reforço para edifícios existentes de betão armado, particularmente edifícios com comportamento potencialmente condicionado pelos mecanismos tipo soft-storey. Foram estudados duas estruturas de edifícios de betão armado, representativas de algumas famílias de edifícios existentes em países do sul da Europa. Para ambas as estruturas estudaram-se dois cenários, num deles considerou-se a existência de painéis de alvenaria de enchimento em todo o edifício excetuando ao nível do piso térreo, e noutro considerou-se a inexistência de paredes de alvenaria em todo o edifício. Desta forma estuda-se a influência, já comprovada em trabalhos anteriores, dos painéis de alvenaria na resposta dos edifícios à ação sísmica. A ferramenta numérica utilizada neste trabalho para a simulação do comportamento dos edifícios é o programa SeismoStruct. Foram realizadas análises não-lineares, estáticas e dinâmicas, para a avaliação do comportamento desses edifícios face às ações sísmicas. Foram implementadas nos modelos numéricos diferentes soluções de reforço, nomeadamente: o encamisamento de pilares recorrendo ao betão armado, a adição de paredes resistentes de betão armado, a introdução de contraventamentos metálicos e contraventamentos metálicos com dissipadores de energia. Os resultados das análises da resposta dos edifícios reforçados são confrontados com os respetivos resultados das estruturas originais, deduzindo-se sobre a melhoria do desempenho estrutural com cada tipo de reforço estudado.
The assessment of vulnerability and retrofit of existing buildings, particularly in what concerns to their seismic safety, is a topic of high importance and emergency, as evidenced by the recent earthquakes around the world, particularly in countries of southern Europe. Thus, it is recognized that attention should be given to research in the theme of analysis and strengthening of existing buildings. Some architectural solutions adopted in decade of 1970, combined with the practice at that time of the structural design, and particularly in simplified or nonexistent seismic calculation, made many of these structures have an associated high vulnerability, and may suffer high damages if requested by an earthquake. The objective of this work was to study different solutions to improve seismic safety of existing reinforced concrete buildings, particularly with potentially soft-storey mechanism. Two reinforced concrete buildings, representing existing buildings in southern of Europe have been study. For both buildings it was studied two scenarios, one of them considered the presence of masonry infill panels in entire building except the ground floor, and another considered the absence of masonry infill panels throughout the building. It was observed the influence, already proven in previous works, of the masonry infill panels in seismic response. The numerical tool used in this work to simulate the behavior of buildings is the program SeismoStruct. Nonlinear analyses, static and dynamic, have been tested to evaluate the behavior of these buildings against seismic actions. Different retrofit techniques have been tested, namely: reinforced concrete jacketing, addition of reinforced concrete shear walls, addition of steel bracings and addition of steel bracings with energy dissipation systems. The results of the response of reinforced buildings are faced with the respective results of the original structures, deducting about the structural performance of each type of retrofit technique studied.

No processo da aquisição fonológica, uma das estruturas que tem despertado o interesse de estudiosos sob diferentes perspectivas teóricas é o onset complexo, formado por sequências de consoantes obstruintes seguidas pelas consoantes líquidas /l/ e /r/ (por ex. /br/aço, /pl/anta, /tr/abalho, /fr/aco). Esta pesquisa se ocupou da aquisição do onset formado pela obstruinte seguida do flap (C(r)) na língua portuguesa. A estrutura do onset complexo no português como em outras línguas é considerada o padrão silábico de maior grau de complexidade, somente alcançando a estabilidade dentro do sistema fonológico da criança em estágios tardios da aquisição. Além disso, o C(r) pode ser apresentado em suas variantes através de produções consideradas estigmatizadas como a metátese e o apagamento da C2. Este estudo tem o objetivo de demonstrar que somente uma abordagem multidimensional pode adequadamente explicar o processo de aquisição do C(r). A explicação da aquisição fonológica é uma tarefa complexa e frequentemente mediada por uma variedade de fatores como: complexidade articulatória, sonoridade, frequência (de type e token) das formas em questão na língua, e a influência de universais linguísticos (por ex., efeitos de marcação), além das questões sociais como nível socioeconômico, idade, sexo, nível de escolaridade. Para o estudo sobre a produção de onsets complexos C(r), foram selecionadas 38 crianças sem dificuldades auditivas e desvios fonológicos, com idade entre 2 e 6:11 anos, frequentadoras de uma creche pública da cidade do Recife. Para a análise dos dados, as crianças foram divididas em 10 grupos etários com intervalo de seis meses entre eles. Utilizou-se um conjunto de instrumentos de coleta de dados, sendo eles: 30 gravuras para serem nomeadas; 21 objetos ou miniaturas para serem nomeadas e uma lista de 93 palavras para serem repetidas que apresentavam sequências C(r). Além disso, também foi aplicado um questionário com escala do tipo likert que abordou a percepção das três professoras e de duas auxiliares sobre a frequência de input e output das palavras desta pesquisa relacionadas às crianças deste estudo. Os dados de produção foram analisados pelo programa estatístico Goldvarb X (SANKOFF et al, 2005). Os resultados demonstraram que os fatores: tonicidade, primeira consoante, extensão da palavra, vogal seguinte, posição da sílaba, idade, escolaridade e frequência são fundamentais no processo de aquisição do C(r). Além de interagirem entre si, a sensibilidade da criança sobre a especificidade da língua também é um fator que contribui durante o percurso da aquisição do C(r). Espera-se que este trabalho possa contribuir para um maior alcance/entendimento do quadro geral não só da aquisição do encontro consonantal C(r) do português em diferentes regiões do país, como também do próprio sistema fonológico da língua, em face às suas variedades sociais.

Resumen
The moral imperatives of hunting have long been associated with masculinity. In Britain's age of High Imperialism, hunting assumed greater importance as a 'right of passage' necessary for personal assertion and imperial stability. For proponents, killing wildlife for sport was a 'natural' process which illustrated the ethnocentric and cultural superiority of British upper class men over various "others". This 'pre-eminence' manifested itself through 'male' institutions including elite education, church, army and hunting clubs and found wider expression through hunting books and museums. Dissidents from this pleasing masculinity railed at the celebration of hunting as 'character' training, in particular, the 'objectification' of animals for 'sport'. The ubiquity of the hunting image in the age of High Imperialism, however, was evidence of hunting's popularity as a 'maker of men' despite the concerns of humanitarians.

Resumen
SOFTWARE DEVELOPMENT FOR R/C BUILDING VULNERABILITY INDEX AND MEMBER IMPORTANCE CALCULATION Turkey has many active faults which have the potential to generate large earthquakes. Recent earthquakes showed that the buildings in Turkey are not well designed and vulnerable to earthquakes. Previous studies on the subject showed that many structures in Turkey need to be strengthened before the next major earthquake to minimize property loss and casualties. A number of fast and approximate (mostly empirical) methods have been developed in the past to process large building stock. However, there are some important and special structures that do not fit with the general building stock and needs special consideration (e.g., disaster management center, governmental buildings, hospitals, tall structures, etc.). This study targets to evaluate those important and special structures in a detailed, fast, and correct manner. The developed software, which constitutes an important part of this study, does process the building information several times to determine member-based importance factors. The vulnerability index of the building will be determined using the importance of each load-carrying member and how much each member is forced with respect to its capacity. In order to augment user perception, a functional graphical user-interface is designed. Software is equipped with modules that generate input files for SAP2000 analysis program, conduct dynamic and static analysis automatically, and postprocess the generated analysis results which enable the engineer to make a decision on the vulnerability of the structure. Program is written in C++, using object-oriented programming technique. The main difference between this and similar studies is the generator program which automatically generates 3D-FE models and post-processes nonlinear analysis results for an effective decision mechanism. In this way, more realistic results can be obtained much faster. As future studies, new routines are planned to be implemented to the graphical user interface of the program which will suggest smart and engineered retrofit/strengthening alternatives to the user.

Resumen
The C2 molecule is very important astrophysically as well as terrestrially. Its spectrum is known from the comets, the interstellar mediums and the atmospheres of cool carbon stars. C2 is present in flames and electric discharges through carbon-containing materials, and could be important at the edge of fusion plasmas. Nevertheless, there seem to be no preceding published studies of electron collisions with neutral C2. On the other hand, there are a number of studies available for C2 ion. The challenge of studying electron collisions with C2 is the unusually large number of low-lying electronic states, which are themselves difficult to represent using standard ab initio methods. Furthermore, the system supports several bound states even though the exact number is not firmly established. This thesis describe the electron collision processes with the dicarbon molecule and its anion at the energies up to 10 eV. Specific attention is given to determine the formation of the bound states of C2 and a low-lying resonance of C as a function of internuclear separation. While the calculations on the system used the standard implementation of the UK i-matrix method, those on C required both the molecular .ft-matrix method with pseudo-states and the partitioned /2-matrix method to be employed. The effectiveness of these procedures for this problem is discussed.

Resumen
Commutative algebra is the study of commutative rings and other abstract structures based on commutative rings. Modules can be viewed as a common generalization of several of those structures, and some invariants, e.g. homological dimensions, of modules are used to characterize certain properties of the base ring. Some generalizations of such invariants include C-Gorenstein dimensions, where C is a semidualizing module over a commutative noetherian ring. Holm and Jørgensen [16] investigate some connections between C-Gorenstein dimensions of an R-complex and Gorenstein dimensions of the same complex viewed as a complex over the "trivial extension" R × C. I generalize some of their results to a certain type of retract diagram. I also investigate some examples of such retract diagrams, namely D'Anna and Fontana's amalgamated duplication [8] and Enescu's pseudocanonical cover [9].
