Full textSince the achaemenid period, Media lies a singular place between Mesopotamia and countries of the Iranian Plateau. It orders the access of both and is crossed by the Royal Main road which allows to connect Bactra. The Achaemenid kings make moreover of Ecbatana their summer residence, allowing them to control a hostile renowned territory, that of the mountains of Zagros, lived here by Cosseans. In fact, these are the Greek authors posterior to Alexander that deliver us a negative testimony of these mountain peoples : so, a re-examination of the literary documentation, numismatics and epigraphy allows to encircle the consequences of the Macedonian conquest in Media and to see the evolution of the territorial organization from the Seleucids to the Parthians. Seleucid kings make Ecbatana an important relay of the royal power, the authority of the satrap of Media also extending farther East, but, until the reign of Antiochus III, the territory of seleucid Media appears all the same to have missed coherence. Moreover, since Antiochos I, if Ecbatana certainly keeps its status of political capital of the High Satrapies, it is Seleucia on the Tigris who henceforth seems to have become the economic and financial capital. The policy of the Parthian kings, partly inheritance of that of Seleucid, marks a supplementary stage in the appropriation of the space, with a territorial integration in the interregional scale, containing Media and Babylonia : seleucid commons and contemporaries monograms of the mints of Seleucia and Ecbatana, then the division of labor operated in the parthian period between both mints are the proof

Full textLa creciente demanda de compuestos enantioméricamente puros, ha incrementado el interés por el desarrollo de metodologías para la obtención de dichos compuestos. Entre ellas, la catálisis asimétrica es la técnica mas utilizada. En dicha metodología, la elección del ligando quiral es clave para la obtención de elevada actividades i enantioselectividades. En este contexto, esta tesis se centra en la síntesis de diferentes familias de ligandos quirales altamente modulares a partir de productos de partida de elevada disponibilidad. Más concretamente, se ha trabajado en la síntesis de ligandos heterodadores P-oxazoline (P= fosfina, fosfinito, fosfito, fosforamidito), P-otros grupos N-dadores (P= fosfito, fosforamidito, fosfonito y N= tiazol, sulfoximina, hidrazona, amina, piridina), P-tioéter (P= fosfina, fosfinito, fosfito) i una familia de ligandos fosfina quiral-fosfito. Estos ligandos se han aplicado en la reacción de hidrogenación de olefinas funcionalitzadas i mínimamente funcionalitzadas catalizada por Rh i Ir, la reacción de substitución alílica y la reacción de protonación descarboxilativa de oxindolas ambas catalizadas por Pd. Además, en algunos casos, se han realizado cálculos computacionales en combinación con ensayos experimentales para estudiar el origen de las enantioselectividades obtenidas o bien para guiar la optimización de los ligandos.
The growing demand on enantiomerically pure compounds has stimulated the interest for the development of methodologies to obtain these compounds. Among them, asymmetric catalysis is one of the most employed tools. In this technic, the choice of the chiral ligand is fundamental to obtain high levels of activity and enantioselectivity. In this context, this thesis is focused on the synthesis of several families of highly modular chiral ligands from readily available starting materials. Particularly, we worked on the synthesis of P-oxazoline (P= phosphine, phosphinite, phosphite, phosphoroamidite), P-other N-donor groups (P= phosphite, phosphoroamidite, phosphonite and N= thiazole, sulfoximine, hydrazone, amine, pyridine), P-thioether (P= phosphine, phosphinite, phosphite) and a family of P*-stereogenic phosphine-phosphite ligands. These ligands have been applied in the Rh- and Ir-catalyzed hydrogenation of functionalized and minimally functionalized olefins, Pd-catalyzed allylic substitution reaction and Pd-catalyzed decarboxylative protonation. Furthermore, in some cases, DFT studies in combination with experimental ones have been performed to better understand the origin of the obtained enantioselectivities or in order to guide the ligand optimization.

Full textSince 1980 the acp states have adopted clear and well-defined legislation to allow prompt compensation in case of nationalizations and free movement of capital. On the other hand most member states of the european communities have concluded investment protection agreements with a large number of acp states. By such agreements, the acp states guarantee standards of treatment and protection for european investment and the ec member states offer eligibility ot their national insurance systems. On the basis of the comparative description of the european investment agreements, the question has been raised to know whether these agreements are reflecting international customary law. Nevertheless, the protective standards in the bilateral agreements present important deviations and the analysis of the guarantee conditions reveals the differences in member states guarantee systems and the subsequent distortions of competition between european investors. The search for a multilateral approach with regard to the protection of european investments has lead to the absorption of the principles and rules contained into the bilateral agreements into the lome conventions. Besides, the lome onventions recognize the importance of specific agreements for individual projects in the mining and energy sector and the utility of promoting the international investment by participation with risk capital-especially for small and medium-sized business. The question of a common eec-acp guarantee system remains open

Full textThe construction of the europe combines three aspects at the same time, that is to say, a project, a method and a space that europeans have agreed together to construct - europe, deliberately but step by step. . . At the beginning of the sixties, the acp states signed agreements aimed at maintaining and extending their links with the european economic community. The acp have been directly connected and dealt with collectively in regards to work, particularly on the the level of financial and technical co-operation. The modes and procedures of setting up co-operation comprise four broad phases: -programming, instruction, decision-making and (evaluation of)results. Today europe has initiated the project for a single currency that the acp states consequently have to deal with in order to master this co-operation. However, this project raises various obstacles and socio-political risks wich we have already discussed. Finally, what will the strategy for development of the acp be tomorrow, particularly in the case of congo(zaire) ? it is not simply a question of preaching and isolation of the acp states, but rather concentrating on development tomorrow, which means necessarily strengthening the internal economic and social structures. And why not include co-operation in the new international economic order ?

Full textIn the field of antimony, the first 1,2-distibacyclobutane with a SbSbCC sequence was isolated. Its formation involves the transient stibaallene ArSb=C=CR2 (Ar = 2,4,6-tri-tert-butylphenyl, CR2 = fluorenylidene) followed by a head-to-head dimerization via two Sb=C double bonds. Molecular orbital calculations at the ab initio and DFT levels have been performed to understand the competition between head-to-head and head-to-tail dimerization. Attempts to synthesize the phosphastibaallene ArSb=C=PAr and reactions of di- and trisubstitution of antimony will be described. Concerning tin, a stable distannirane, the first stannic analogue of cyclopropane, was isolated and its structure was confirmed by X-ray analysis. Because of the probable lability of the tin-carbon double bond, the transient stannaallene Tip2Sn=C=CR2 (Tip = 2,4,6-triisopropylphenyl) could dissociate into carbene and stannylene, thus a reaction between the latter and the stannaallene should lead to the distannirane

Full textThe present work was carried out in three different goat raisings and 27 females and 2 males were selected for identifying the present microbiota in the preputial and vaginal cavity of goats under three estrous cycle phases: In Februrary, 2005 in the pro-estrum, in May, 2005 in the post-copula and in October, 2005 in the post-partum. The samples were collected by swabs as well as vaginal and preputial washings for studying microbiota and by gynecological brushes for the females esfoliative cytological study. The two greatest bacteria genera prevalence were: Micrococcus spp (89,65 %) following by Bacillus spp. (29,90 %). Filamentous fungi as Cladosporium spp. (26,39 %) and Aspergillus spp. (11,46 %) were the most isolated. On the bacteria cytological test about 76 % of the investigations have been in accordance with the microscopic finding and bacteria isolation. In 89% appraised animal some yeasts presence on sheets was observed in spite of there was isolation just in 7,4 % of the animals. There was similarity between hifas observation and filamentous fungi isolation, in regarding to 53 % of hifas presence investigations. The bacterial and fungical microbiota found on this survey showed the goats vaginal and preputial microbiota diversity and pointed out to the fact that it might be carried during copulation. The number of isolated bacteria species in the post-copulation phase was upper, as well as for yeasts. The vaginal cytology performed significative association in relation to the bacterial isolation, observed by cocos and bacilli presence on the sheets with positive growth. Bacteria potentially pathogenic as Pseudomonas alcalinigenes, P. aeruginosa, and Corynebacterium spp. as well as opportunist fungi as Aspergillus flavus in healthy goats vaginal cavity were found.
O presente trabalho foi desenvolvido em tr?s criat?rios caprinos distintos, de onde tomamos 27 f?meas e 2 machos a fim de identificar a microbiota presente no prep?cio de bodes e na cavidade vaginal de cabras em tr?s fases do ciclo estral: fevereiro de 2005 no proestro, maio de 2005 ap?s a c?pula e outubro de 2005 ap?s o parto. As amostras foram coletadas atrav?s de swab, lavado vaginal e prepucial para o estudo da microbiota e com escovas ginecol?gicas para o estudo colpocitol?gico das f?meas. Os dois g?neros de bact?rias de maior preval?ncia foram os seguintes: Micrococcus spp. (89,65 %) e Bacillus spp. (29,90 %). Os dois g?neros de fungos de maior preval?ncia foram Cladosporium spp. (26,39 %) e Aspergillus spp. (11,46 %). No estudo colpocitol?gico para bact?rias, em 76 % das investiga??es houve concord?ncia entre os achados microsc?picos e isolamento bacteriano. Em 89 % dos animais avaliados foi observada a presen?a de leveduras nas l?minas, mas houve isolamento em apenas 7,4 % dos animais. Em 53 % das investiga??es da presen?a de hifas houve concord?ncia entre a observa??o de hifas e o isolamento de fungos filamentosos. A microbiota f?ngica e bacteriana encontrada no presente trabalho evidenciou a diversidade da microbiota vaginal e prepucial de caprinos e aponta para o fato de que podem ser carreados durante a c?pula. Observou-se que o n?mero de esp?cies isoladas de bact?rias ? superior na fase de p?s-c?pula enquanto que em fungos observamos este aumento no p?s-parto; O resultado da citologia vaginal teve correla??o com o isolamento bacteriano, observada pela presen?a de cocos e bacilos nas l?minas com crescimento bacteriano positivo; Bact?rias potencialmente patog?nicas como Pseudomonas alcaligenes, P. aeruginosa e Corynebacterium spp. foram encontrados na cavidade vaginal de cabras h?gidas, assim como fungos oportunistas como Aspergillus flavus.

Full textThis thesis is one part of a general research of the novel, non-expensive and environmentally friendly methods for the synthesis of the interesting molecules in the pharmaceutical, agrochemical or material field. In particular, the objective consists of creating the C-C and C-heteroatom (S, N, P) bonds by using copper, manganese catalysis or transition-metal-free system.In the first part, a copper-catalyzed palladium-free Sonogashira reaction has been realized under biphasic conditions (water / organic substrates) allowing decreasing the copper loading up to 0.02 – 0.2 mol% and a potential intermediate species of this reaction, corresponding to a copper cluster linked with acetylide moiety, has been identified by X-ray diffraction.In the second part, we described a novel carbon dioxide involved copper-catalyzed system for the methylthiolation of aryl halides using dimethylsufoxide as a source of methylthio group. The presence of carbon dioxide is a crucial factor for the formation of aryl methyl sulfides products and its role is discussed.The third part describes the manganese-catalyzed homocoupling and cross-coupling reactions via the formation in situ of aryllithium from corresponding aryl halides or arenes. According to the experimental conditions, the symmetrical or unsymmetrical biaryls could be obtained. An intermediate complex of manganese which could involve in the reaction mechanism was detected by ESI-MS.Finally, a transition-metal-free system associating DMF with t-BuOK has been developed to realize the arylation of aromatic halide derivatives and various nucleophiles such as pyrazol, imidazole, dialkyl disulfide or diarylphosphine oxide. This project is at a preliminary stage

Full textThe first part of this manuscript deals with the synthesis of enantioenriched P-stereogenic phosphine-boranes from a chiral precursor developed in our laboratory: H-adamantyl phenylphosphinate. Through the design of a one-pot procedure, the synthesis of a wide array of highly enantioenriched phosphine oxides has been achieved. These hydroxy-functionalised compounds were reduced stereospecifically under borane conditions to yield the corresponding hydroxyalkylphosphine-boranes. During the study of this reaction, the importance of hydroxy group has been highlighted, and a mechanism relying on the formation of transient phosphaboracyclic intermediate could be proposed, on the basis of kinetic observation and isolation of O-borylated intermediates. In this transformation, borane seems to display three roles: activating, reducing and protecting agent. Next, we were able to take advantage of the retroaddition of hydroxyalkyl moiety under basic conditions to develop a new approach for the stereospecific and chemodivergent alkylation of masked secondary phosphine-boranes. This unusual reactivity allowed us to circumvent the relative chemical and configurational instability of such in situ generated phosphido-boranes intermediate, thus enabling the stereospecific synthesis of functionalised tertiary phosphine-boranes. These P-N ligands have been complexed to palladium, and the catalytic activity of these complexes in enantioselective C-C couplings has been studied. During the catalytic process, it appears that the ligand bite angle plays an important role in the catalyst activity

Full textThis thesis is devoted to the study of deformation of C*-algebras endowed with a group action, from the perspective of non-formal equivariant quantization, in the non-Archimedean setting. We construct a deformation theory of C*-algebras endowed with an action of a finite dimensional vector space over a non-Archimedean local field of characteristic different from 2 and for quotients of the affine group of a local field whose residue field has cardinality not divisible by 2. Moreover, we construct families of dual unitary 2-cocycles in order to deform locally compact quantum groups acting on these deformed C*-algebras

Full textThe history of Hispanic towns in the third century has long been written in the shadow of the Barbarian invasions and the "crisis" that allegedly ruined them. Historiographical renewal, initiated in the 1970s, rightly revised this traditional view, but it has left open questions that this thesis has tried to answer. The objective of this research was to study and interpret the variety of urban evolutions and to understand the influence of transformations that followed the third century "crisis", the history of cities and urbanization. This research, using literary, epigraphic and archaeological sources, was conducted by crossing analysis scale of urbanism (urbanization, urban morphology and urban hierarchy). The results indicate that the occupation of most cities was maintained but urbanization didn't progress and even stagnated. The classical urban model has persisted beyond the third century with regular maintenance and restoration. Cities didn't disappear in Hispania during the third century, but their legal status were harmonized. In contrast, there was probably a selection in urbanization that might have related some towns - that lacked sufficient ressources to maintain their status of capital of a city-state - to "secondary towns". Moreover, the transformations of the urban hierarchy promoted the city of the western peninsula at the favor of West and North which were at the late third century the most dynamic cities in the Iberian Peninsula. The third century seems to mark a translation of the urban phenomenon from East to West in the Peninsula

Full textThe classification of the machines of lifting proposed by Vitruve is a tool which allows to consider roman technical capacities, but it hides the variety of ancient devices used in the Antiquity. Except for some copies, every devices which compose the groups of machines differ one from the other. The common point to all these systems is the assemblage of a driving element in a passive part, through an organ of transmission, what confirms the restoration of the machine which fed with water the roman baths of Barzan (Charente-Maritime). The precise study of the archaeological documentation reflects dynamism : the standardization of wooden force pumps and those who evacuate the water from ships testifies of the success of little expensive and effective enough mechanical systems. Moreover, organization of mines, quarries and agriculture in Egypt and as well as equipment of vigiles is the obvious proof of a thorough reflection on the rationalization and the optimization of the tasks to be done. Also, the role of the architect is maybe a little less central than we could we could have assumed. It indeed seems that the influence of the craftsmen, both in the conception and in the manufacturing of machines, is essential. Finally, our study makes appear a strong correlation between the development of the lifting devices and the change of scale of the Roman economy from the end of the Republic and it confirms the importance of the financial investment of the entrepreneurs in the technical progress

V is calculated with the introduction of the dynamical coupling between the two 3π states arising from both asymptotic atomic states. A non B. O. Process is described in a non-orthogonal asymptotic basis of the system. For that purpose both an effective hamiltonian and an effective operator for the dynamical coupling are defined. These operators reproduce the results of an extensive C. L. , and are built by mean of projection method. Two cases are studied : the number of C. L. Eigenvalues are equal or lower to the dimension of the effective basis. The charge exchange is studied through an effective diabatic representation of a3π and d3π states. The scattering equations are solved by a fuil quantum treatement and the rate coefficient is obtained after maxwellian average over velocities

Full textThe aim of this study was to evaluate the influence of the carbon/nitrogen (C/N) and carbon/phosphorus (C/P) ratio in hydrogen (H2) production in anaerobic fluidized bed reactor (AFBR) containing grounded tire as support material for microbial adhesion. Synthetic substrate containing glucose (5,000 mg L-1) was used as the carbon source, and the effluent pH remained ±3.7. Four reactors were operated with C/N=100 (R1), C/N=150 (R2), C/N=200 (R3) and C/N=250 (R4), under mesophilic conditions. The reactors were operated for 18 months and the experiment was divided into three phases: in the 1st Phase, the C/P ratio was maintained at the value of 300 and hydraulic retention time (HRT) was varied in 8, 6, 4, 2 and 1 h; in the 2nd phase, the HRT was kept at 2 h and the C/P ratio was varied in 300, 500, 700, 900 and 1100; and in the 3rd Phase, the HRT was kept at 8 h and C/P ratio varied in the values of 300, 500, 700, 900 and 1100. The highest values of hydrogen production (HPR) were obtained in R3 (C/N=200), HRT of 2 h and C/P=700 (0.70 L.h-1.L-1) and they were related to fermentative pathways of ethanol and acetic acid production. The highest values of hydrogen yield (HY) were obtained in HRT of 8 h, R3 (C/N=200) and C/P=300 (1.758 mol H2.mol glucose-1) and they were related to fermentative pathways of ethanol, butyric and acetic acid production. The highest value of ethanol yield (EtOHY) (1.8 mol EtOH. mol glucose-1) was obtained in the 2nd Phase. By means of DGGE analyses was found highest similarity between C/P=700 and C/P=900 for R1 (87%), R2 (97%) and R3 (92%) in the 2nd Phase. Through phylogenetic affiliation of the 16S rRNA gene taken from samples of stages of highest H2 production it were obtained clones of hydrogen and ethanol producing specie related to Ethanoligenens sp., followed by the lactic acid bacteria Lactobacillus sp. and of the acetic and butyric acid producing Clostridium sp..

Full textLectinas são moléculas que possuem a capacidade de reconhecer carboidratos específicos e têm sido bastante utilizadas em importantes técnicas laboratoriais. Lectinas imobilizadas são utilizadas para estudo de glicoconjugados através da cromatografia de afinidade. O isolamento de glicoproteínas através dessa técnica e a avaliação de seu poder de ligação a várias lectinas tem fornecido informações importantes a respeito de suas cadeias oligossacarídicas e das suas possíveis modificações. Patologias como câncer, processos inflamatórios e doenças hepáticas têm sido relacionadas com alterações da porção carboidrato. O presente estudo tem como objetivo avaliar a capacidade da lectina de sementes de Cratylia mollis (cra) e a Concanavalina A (Con A) em isolar glicoproteínas plasmática de pacientes com esquistossomose mansônica, uma doença hepática inflamatória, nas diferentes fases clínica da doença: hepato-intestinal (HI), hepatoesplênica compensada (HEC) e hepatoesplênica descompensada (HED). Cra e Con A foram hábeis no isolamento de glicoproteínas plasmáticas de pacientes esquistossomóticos nas diferentes formas clínicas. O processo cromatográfico realizado a 4 °C demonstrou uma maior capacidade dessas lectinas em adsorver glicoproteínas quando comparado ao realizado a temperatura ambiente (27 °C). Um aumento na reatividade de glicoproteínas foi observada para os pacientes nas fases HED e HEC. As glicoproteínas caracterizadas por eletroforese em gel de poliacrilamida contendo sulfato sódico de dodecila, sob condições desnaturantes e redutoras, determinaram padrões diferentes das formas HEC e HED onde o surgimento de bandas protéicas e outras bandas mais coradas definiram a diferença em relação aos indivíduos controles e hepato-intestinal

Full textA methodology dealing with the preparation of enantioenriched P-stereogenic alkenylphosphines by asymmetric catalysis has been proposed. It is based on the palladium C-P cross-coupling reaction between secondary phosphine-boranes and alkenyltriflates. This study was carried out in racemic and enantioselective versions. In the racemic version, a general and efficient method enabling the coupling of alkenyltriflates was developped. Chiral or achiral diaryl-, alkylaryl- and dialkylalkenylphosphines were easily prepared under mild conditions, using a weak base (K2CO3 or K3PO4) and a mild thermal activation (60 to 80 °C). With the cheaper but less reactive alkenyltosylates, higher temperatures (80 to 110 °C) were required to perform the coupling. The alkenylphosphines were isolated in good yields (50 to 90%). In the enantioselective version, a catalytic system enabling to perform the coupling efficiently was designed. It involves the palladium catalyst [(S,S)-Me-DUPHOS]PdCl2. Optimization of the other parameters allowed us to synthesize an enantioenriched alkenylphosphine with an enantiomeric excess of 55%. A mechanistic study has enabled us to propose a mechanism and to confirm the individual steps in the catalytic cycle. The oxidative addition complex and the transmetallation adduct were fully characterized. A dynamic kinetic resolution was proposed to rationalize the enantioselectivity
