Résumé :

Written as a two-fold dissertation on Ph.D. studies of composition at the Faculty of Music in Belgrade, which consists of the piece and the autopoetic text, Ana Gnjatović's Phonations for voice and electronics (2016), raises, among others, questions of performance of music for voice and electronics, as well as issues of the composer's/performers voice, and the topic of (musical) memory. Focusing on these problem points, this paper deals with Ana Gnjatović's 'vocal identity, represented and performed in the layering sounds of voice and electronics, with Edward T. Cone's notion of 'composers voice in mind.

Résumé :

GordonAda, an outstanding virologist and immunologist,was the first to demonstrate that the influenza virus genome is composed of RNA, not DNA. In immunology he provided evidence that refuted the template theory of antibody formation and performed elegant experiments to prove Burnet's Clonal Selection Theory. His administrative skills created a research environment that nurtured the Doherty-Zinkernagel Nobel Prize in viral immunology and allowed him to assist WHO and others greatly in developing effective vaccines.

Résumé :

A one-pot, three-component, Cu(I)-catalyzed coupling of primary hydrazines, 5-chloropentan-2-one, and terminal alkynes was developed. The resulting 1-aza-6,7-dehydrotropanes compose a new class of substances while related 1-azatropanes are scarcely described in literature and closely resemble tropane alkaloids. Hydrogenation of the double bond in 1-aza-6,7-dehydrotropanes triggered a rearrangement, involving a [1,3]-hydride shift, forming cyclic hydrazones.

Résumé :

Enchanted by the vocal music of Serbian-born Canadian composer Ana Sokolović, Tamara Bernstein visited the composer at her home in Montreal. Sokolović’s music draws on several sources, including the theatrical world and the culture of the Balkans. The extended vocal techniques in Sokolović’s music are rooted not in the avant-garde music of the twentieth century, but in the oral traditions and poetic voice of Serbia. It seems that the more the composer returns to her cultural roots, the more she embraces the universality of the human soul.

Résumé :

Pautados em uma perspectiva discursiva de linha bakhtiniana, compreendemos a ata como uma manifestação social específica, fruto de condições concretas de produção e materializada em um texto com diversas peculiaridades estruturais e linguísticas. Nesse sentido, propomos, neste artigo, um estudo do estilo do gênero Ata. Para tanto, buscamos retomar a concepção de gênero do discurso a partir de Bakthin (1997), levantamos orientações técnicas a respeito da textualização das atas de acordo com o Manual de Redação da Presidência da República e opomos os dados levantados às ocorrências linguísticas verificáveis em um conjunto de atas institucionais selecionado. A análise dos dados indicou que, apesar dos manuais de redação oficial definirem a ata como um relato fiel das discussões e decisões de uma reunião, a objetividade anunciada para esse gênero apresenta brechas em que o secretário/redator atua, como a seleção de informações e de vocabulário a comporem o texto. Tais escolhas caracterizam-se como pontos de ancoragem da subjetividade nas atas. Palavras-chave: Discurso. Gênero ata. Secretariado. ABSTRACT Based on a discursive perspective of Bakhtinian line, we understand the meeting minutes as a specific social manifestation, product of concrete conditions of production and materialized in a text with diverse structural and linguistic peculiarities. In that sense, we propose, in this paper, a study of the genre Minutes. To that end, we retrieved Bakhtin’s (1997) conception of discourse genre and gathered technical guidance as to the minutes textualization according to the Writing Manual e of the Republic Presidency. We then contrasted the data gathered to the verifiable linguistic occurrences in a selected collection of institutional minutes. The data analysis indicated that, even though the official writing manuals define the minutes as a faithful report of the discussions and decisions of a meeting, the objectivity announced for this genre presents gaps in which the secretary/writer acts, as in the selection of information and vocabulary that compose the text. Such choices are defined as anchoring points to the subjectivity of the minutes. Keywords: Discourse. Meeting minutes genre. Secretariat.

Résumé :

Le but de ce travail etait de preparer de nouveaux composes spiroindolo, -quinoleino, -benzazepinopiperidiniques. Pour ce faire plusieurs strategies ont ete etudiees, et en particulier deux strategies faisant appel a des reactions d'arylation intramoleculaires selon un processus radicalaire et/ou un processus d'arylation intramoleculaire de type heck. Ainsi l'acces a de nouveaux composes spiroindolopiperidiniques a ete pu etre realise via une strategie incluant une reaction d'arylation de type radicalaire ou de type heck. Dans ce cas la strategie dite radicalaire s'est revelee beaucoup plus efficace. D'autre part, dans le cas des composes spiroquinolein, -benzazepino, piperidiniques seule une strategie incluant une reaction d'arylation de type heck a permis d'obtenir les cibles desirees. Enfin, un acces rapide a des composes spiroquinoleinopiperidiniques a ete mis en evidence via des reactions de couplage catalysees par les sels de cuivre.

Résumé :

Ce mémoire de thèse présente deux aspects principaux consistant premièrement en une étude méthodologique de métallation de substrats aza-π-déficients et deuxièmement en la synthèse par voie organométallique et / ou couplage par métaux de transitions de synthons à fort intérêt biologique potentiel. Ainsi, les travaux présentés décrivent, dans un premier chapitre, les résultats d’essais de métallation régiosélective de composés aza-π-déficients tels que le 7-azaindole ou la pyrazine via la superbase complexe [n-BuLi / LiDMAE]. Par ailleurs, des résultats relatifs aux essais complémentaires sont proposés à partir d’autres superbases complexes dérivant de celle-ci telles que [s-BuLi / LiDMAE], [t-BuLi / LiDMAE], [LDA / LiDMAE], [LTMP / LiDMAE]. Ces essais ont été réalisés sur un substrat modèle, la 3-chloropyridine, permettant une étude approfondie des aspects régiosélectifs et du ratio Basicité / Nucléophilie des complexes basiques étudiés. La seconde partie de cette thèse présente la synthèse de molécules cibles bicycliques azotées fonctionnalisées et fonctionnalisables telles que la pyrano[3,2-b]pyridine et l’oxépino[3,2-b]pyridine par voie organométallique, couplages par métaux de transition et métathèse des oléfines. Pour cette dernière étape, une étude méthodologique a été menée comparant les catalyseurs de Grubbs première et deuxième générations en optimisant pour chacun d’eux le rendement de la séquence en fonction de la quantité de catalyseur introduite. Enfin nous avons envisagé la formation de thiéno[3,2-b]pyridines fonctionnalisées et fonctionnalisables par lithiation régiosélective suivie de couplage de Sonogashira et de cyclisation électrophile
This thesis presents two principles aspects: the first one consists in a regioselective metallation methodologic study of aza-π-deficients systems, and the second one, in the synthesis of highly biological interest scaffolds by organometallic way and / or transition metals couplings. So, in a first chapter, we describe the different results of the reaction between the superbasic complex [n-BuLi / LiDMAE] on π-deficient systems such as 7-azaindole or pyrazine. We also present results of other but close superbasic systems [s-BuLi / LiDMAE], [t-BuLi / LiDMAE], [LDA / LiDMAE], [LTMP / LiDMAE] on a model substrate: 3-chloropyridine. Indeed, this substrate allowed us to study regioselectivity and Basicity / Nucleophilicity ratio aspects. The second part of this thesis describes the synthesis of functionalised and functionalisable bicyclic targets especially containing a nitrogen atom such as pyrano[3,2-b]pyridine and oxepino[3,2-b]pyridine using an organometallic way, followed by transition metal couplings and ring closing metathesis. For this last step, we studied the efficiency of first and second generation Grubbs’ catalysts, comparing each, and optimising for each the yield of product obtained compared to the amount of catalyst introduced. Finally, we envisioned the formation of thieno[3,2-b]pyridines functionalised and functionalisable by regioselective lithiation of 3-methylthiopyridine followed by Sonogashira coupling and electrophilic cyclisation

Résumé :

Notre travail rapporte la synthèse de calix[4](aza)couronnes et l'étude de leurs propriétés de complexation et d'extraction vis-à-vis des cations alcalino-terreux, métaux de transition et terres rares. La synthèse de produits de départ (dérivés mono-, di-, tri- et tétra-méthylester du p-tert-butylcalix[4]arène) a été suivie par la préparation de calix[4]arènes pontés par une chaîne azaéthylène ou azapropylène, et leurs dérivés mono- et di-méthylester correspondants. L'intercalation d'un groupement CH2NHCH2 ou CH2N(CH3)CH2 sur la chaîne azaéthylène et leur O-méthylation ont été réalisés. L'introduction d'un "tren" et d'un pontage double conduit respectivement au calix[4]arène triponté et calix[4]bis-(aza)couronne. Une étude complémentaire limitée au 1,3-diméthylester-2,4-diméthoxy-p-tert-butylcalix[4]arène se rapporte à la fois à l'effet de la nature du cation complexé et celle de la polarité du solvant sur la conformation du ligand, et à l'extraction et la complexation compétitive des cations alcalins. Cette étude a permis d'observer le premier cas concret pour lequel la 1H-RMN identifie, à la fois, la nature du cation complexé et le complexe formé. Cette observation ouvre la voie à une nouvelle méthodologie d'identification des complexes. Les résultats de complexation et d'extraction des cations ont mis en évidence une sélectivité prononcée pour Cu2+ qui devrait conduire à des applications environnementales et industrielles, et ont permis l'étude de l'influence d'ajout de fonctions méthylester au niveau du bord inférieur des calix[4](aza)couronnes, de la nature de la chaîne pontante, et du nombre des chaînes sur les propriétés d'extraction et de complexation. Bien que les complexes de terres rares soient stables, aucune sélectivité n'a été remarquée. Toutefois, un effet de coopérativité entre les deux ponts azacouronnes a été mis en évidence. La confrontation des données spectrales, spectroscopiques et cristallographiques identifie la coordination de ces ligands
Our work reports the synthesis of Calix[4](aza)crowns and the study of their complexation and extraction properties towards Alkaline-earth, Transition Metals and Rare-earth cations. The selective synthesis of starting materials (mono -, di -, tri- and tetra-methylester derivatives of p-tert-butylcalix[4]arene) was followed by the preparation of bridged Calix[4]arenes with azaethylene or azapropylene chain, and their corresponding mono- and di-methylester derivatives. The intercalation of CH2NHCH2 or CH2N(CH3)CH2 group on azaethylene chain and their O-methylation was achieved. The introduction of a "tren" and a double bridge led to tripodal Calix[4]arene and Calix[4]bis-(aza)crown respectively. A complementary study limited to 1,3-dimethylester-2,4-dimethoxy-p-tert-butylcalix[4]arene lighten, both, the effect of the complexed cation and solvent polarity on ligand conformation. Furthermore, a competitive complexation and extraction study of alkali cations was run to predict complex stabilities. This study illustrates the first concrete case for which 1H NMR spectroscopy identifies, at the same time, the nature of the complexed cation and the formed complex, and gives rise to a new methodology of complex identification. Results of cation complexation and extraction study showed a pronounced Cu2+ selectivity that can lead to environmental and industrial applications, and allowed to discuss the influence of introducing methylester groups on Calix[4](aza)crowns' lower rim. The effect of cyclisation, the size, nature and disposition of azacrown chains was also investigated on their ion-binding behaviour. However, coordination chemistry of these receptors was discussed. The 1,2- and 1,3- disposition of azacrown chains creates an adequate cavity for transition metals, whereas the 1,2- and 3,4- disposition is adequate for Rare-earth which are strongly complexed. Moreover, a cooperative effect was observed between the two azacrown bridges

Résumé :

Les foldamères d’oligoamides aza-aromatiques s’autoorganisent en structures hélicoïdales et trouvent notamment une application dans le domaine de la reconnaissance moléculaire. Des hélices monobrins à large diamètre en leur centre et à diamètre réduit aux extrémités définissent alors une cavité centrale isolée du milieu extérieur, tapissée à la fois de donneurs et d’accepteurs de liaisons hydrogènes, permettant l’encapsulation de molécules invitées. Cette thèse cible l’élaboration de foldamères originaux dont la structure hélicoïdale, indispensable à la reconnaissance moléculaire, sera induite grâce à la coordination à un centre métallique. Ce changement conformationnel est basé sur la présence d’un maillon central judicieusement défini jouant le rôle de charnière moléculaire. Le maillon clé étudié dans ce travail est un enchaînement pyridazine-pyridine-pyridazine inséré dans deux séquences oligoamidiques pour générer deux foldamères modèles. Après la description de la synthèse de ces cibles, leur complexation à différents métaux a été étudiée. Le concept de charnière moléculaire, permettant d’induire la structure hélicoïdale de façon parfaitement contrôlée, a été validé. Pour finaliser ce travail, une étude d’encapsulation de différentes molécules hôtes a été menée sur cette nouvelle génération de foldamères. Un autre aspect abordé dans cette thèse est l’élaboration d’un foldamère à haut poids moléculaire, spontanément replié sous forme d’hélice, et possédant une cavité centrale élargie pour anticiper l’encapsulation de substrats volumineux
Aza-aromatic oligoamide foldamers self-organise in helical structures and can find an application in the field of molecular recognition. Single-stranded helices with a wide diameter at their centre and a shortened diameter at their extremities define a central cavity isolated from external medium and covered with hydrogen bonding acceptors and donors, which allow guest molecules to be encapsulated. This thesis aim at the elaboration of original foldamers whose helical structure, required for molecular recognition, will be induced through metal coordination. This conformational change is based on the presence of a carefully designed central linker that acts as a molecular hinge. The key linker studied in this work is a pyridazinepyridine-pyridazine compound introduced in two oligoamide sequences in order to generate two model foldamers. After the description of the synthesis of these targets, their complexation to several metals has been studied. The concept of molecular hinge, allowing to induce the helical structure in a totally controlled manner, has been validated. In order to conclude this work, an encapsulation study of several guest molecules has been conducted on this new generation of foldamer. Another aspect addressed in this thesis is the design and the synthesis of a high molecular weight foldamer, spontaneously helically folded, and possessing an enlarged cavity to anticipate the encapsulation of large substrates

Texte intégral

Résumé :

Le travail décrit dans ce mémoire porte sur l'étude conformationnelle des aza-β3-peptides et de leurs dérivés macrocycliques. Des études cristallographiques et spectroscopiques nous ont permis de montrer que les aza-β3-peptides sont des foldamères dont la conformation repose sur un réseau ininterrompu de pseudocycles à 8 chaînons (C8). Cette divergence par rapport aux β3-peptides correspondants repose sur une interaction qui implique l'atome d'azote pyramidal. Ce contact joue un rôle important dans la dynamique de repliement des aza-β3-peptides et entraîne la formation de liaisons hydrogène bifides (hydrazinoturns). Les aza-β3-peptides peuvent être décrits comme une succession de plans articulés autour de centres chiraux. Associée à l'inversion pyramidale de l'azote, cette caractéristique leur confère des propriétés favorables pour la macrocyclisation. L'analyse conformationnelle des macrocycles à 16 et 24 chaînons révèle un fort ralentissement du phénomène d'inversion pyramidale.

Résumé :

Le noyau indazole est certainement l'hétérocycle le moins étudié pour la préparation de nouveaux composés valorisables en chimie médicinale. Dans le cadre d'un programme de recherche sur la synthèse et les propriétés pharmacologiques de 2-azabioisostères de la tryptamine, mélatonine et sérotonine, la synthèse de 2-azatryptophanes a été développée avec plusieurs stratégies : par une substitution nucléophile d'un 3-bromométhylindazole par un acétamidomalonate aménagé pour obtenir soit l'amino ester soit l'amino acide en fonction du traitement, par le couplage de Heck de 3-iodoindazoles protégés et du 2-(acétylamino)acrylate, et par la synthèse de 3-formylindazoles qui ont réagit avec un phosphonate correctement fonctionnalisé dans une réaction de Wittig-Horner. Lors de cette dernière méthode, un composé clef a été étudié permettant la synthèse d'une toute nouvelle librairie de 3-cétoindazole par conversion directe de N-méthoxy-N-méthylamides (amides de Weinreb). De plus, pour développer de nouveaux composés organoborés en chimie organique, la transformation de nombreux halogénoindazoles protégés en leurs boronates correspondants a été étudiée. Leurs utilisations dans des couplages métallo-catalysés de Suzuki-Miyaura et dans des réactions d'hydroxydéboronation a ensuite été évaluées. Enfin, la triple réactivité de dihalogénoindazoles comme plateforme valorisable à de nouvelles librairies d'indazoles a été explorée, en particulier vers des couplages séquentiels de Suzuki et de Sonogashira
The indazole nucleus is certainly the less studied heterocyclic scaffold to prepare new valuable building-blocks in medicinal chemistry. As a part of a research program on the synthesis and pharmacological properties of 2-azabioisosters of tryptamine, melatonine and serotonine, the synthesis of 2-azatryptophans was developed with various strategies : the nucleophilic substitution of a 3-bromomethylindazole with a functionalized acetamidomalonate to obtain either the amino ester or the amino acid according the treatment, the Heck cross-coupling reaction of protected 3-iodoindazoles and methyl 2-(acetylamino)acrylate, and the synthesis of 3-formylindazoles which reacted on a correctly functionnalized phosphonate in a Wittig-Horner reaction. With this last strategy a key compound was study to allow the design and synthesis of a new 3-ketoindazole librarie by a direct conversion of N-methoxy-N-methylamides (Weinreb amides) to ketones. Furthermore to develop new organoboron compounds in organic chemistry, the reaction of various protected halogenoindazoles into the corresponding boronates was studied. Their usefulness were studied in Pd-catalyzed Suzuki-Miyaura cross-coupling reactions and in the hydroxydeboronation. And then the triple reactivity of dihalogenoindazoles to design new indazole libraries was developed, in particulary with sequential Suzuki and Sonogashira cross-coupling reactions

CAPES
A síntese de biciclos nitrogenados tem atraído muita atenção na área de síntese orgânica devido à diversidade de atividades biológicas observadas em compostos que possuem esses núcleos, os alcalóides. Recentemente foi desenvolvida uma nova metodologia para a síntese de biciclos 2-piridonas, via reação de aza-anelação formal [3+3] de enaminonas utilizando o derivado metoximetilênico do ácido de Meldrum. Com isso, foram propostas modificações estruturais nesses biciclos, como reações de esterificação e hidrólise das porções ácido e éster dos biciclos 2-piridonas, reação de descarboxilação, substituição da porção ácido carboxílico por amina (Rearranjo de Curtius) ou por bromo (Reação de Hunsdiecker), síntese de acil hidrazinas, e reações de redução. Foi esse estudo foi possível uma melhor compreensão da sua reatividade, uma vez que modificações seletivas, nos substituintes reativos dos núcleos 2-piridonas, foram observadas. Os resultados levaram à obtenção de compostos inéditos, com diferentes funcionalizações, e para o caso de reações envolvendo compostos quirais, as purezas ópticas foram mantidas, com rendimentos de moderados a bons. O produto da reação de redução forneceu um intermediário avançado para a síntese do alcalóide taxiromina

Grâce à la réaction de l'espèce lithiée avec une grande variété d'électrophiles, nous avons pu obtenir de nombreux nouveaux dérivés de benzodiazines difficilement accessibles, voire impossibles à préparer, par les méthodes traditionnelles. Nous avons appliqué cette méthode à la synthèse de diverses benzodiazines présentant des propriétés biologiquement actives potentielles, comme les analogues de la 4-(3-bromoanilino)-6, 7-diméthoxyquinazoline (inhibiteur de la tyrosine kinase). Dans une deuxième partie, nous avons mis au point la synthèse d'un nouveau aza-analogue du BINAP : la 4-(2'-diphénylphosphino-1'-naphtyl)-2-phénylquinazoline. Nous avons, dans une troisième partie, valorisé l'intéressante régiosélectivité de la lithiation en péri d'azote cyclique de benzodiazines en l'associant à la réaction de couplage pour la synthèse de 4,8- et 4,5-di(hétéro)arylbenzodiazines, susceptibles de présenter des propriétés optiques non linéaires.

As reações multicomponentes (RMCs) são geralmente definidas como um processo em que três ou mais reagentes combinam-se, em um mesmo pot reacional, para formar um produto que tenha características estruturais de cada reagente utilizado, gerando produtos com uma boa complexidade estrutural em apenas uma etapa. Com base nisto este trabalho tem como objetivo a utilização de diferentes compostos de Nióbio como agente promotor de RMC de aza-Diels-Alder. O pentacloreto de nióbio promove a síntese de diferentes derivados de tetrahidroquinolinas através de reação de derivados de anilina e benzaldeíd e diferentes éteres enólicos cíclicos (di-hidropiano e di-hidrofurano), com baixos tempos reacionais, altos rendimentos e com ótimo excesso diastereoisométricos. Foi estudada também, a utilização do pentaetóxido de nióbio na síntese de derivados de cetoaminas bicíclicas através da RMC entre derivados de anilina, benzaldeído e 2 ciclo-hexenona. A reação foi promovida em moderados tempos reacionais, obtendo-se os produtos com altos rendimentos e com moderados excesso diastereoisoméricos, em condições reacionais brandas. Paralelamente aos estudos com os compostos de nióbio, foram realizados estudos de elucidação estrutural de alguns derivados de tetra-hidroquinolinas sintetizados, utilizando técnicas de RMN e cálculos teóricos
The multicomponent reactions (MCRs) are defined as a process wherein three or more reactants combine, in the same reaction pot to form a product that contains the structural characteristics of each reagent utilized, forming products with a good structural complexity in one steep. The aim of this work is the utilization of different niobium compounds as promoter of aza-Diels-Alder MCRs. The Niobium pentachloire promotes the synthesis of different tetrahydriquinolines derivatives through of reaction between anline derivatives, benzaldehyde and different cyclic enolic ethers (dihydropyran and dihydrofuran), with low reaction times, high yields and with great diastereoisomeric ratio. Was studied too, the utilization of niobium pentaethoxide in the synthesis of bicyclic ketamine derivatives through the MCR between anline derivatives, benzaldehyde and cyclohexenone. The reaction was promoted in moderate reaction times, obtaining the products with high yields and with moderate diastereoisomeric ratio, in mild reaction conditions. At the same time of the studies with niobium compounds, were realized studies of unequivocal structural elucidation of some tetrahydroquinoline derivatives synthetized, utilizing NMR techniques and theoretical calculations

Résumé :

This chapter examines the development of African diasporic identities in colonial Peru by focusing on the case of Ana de la Calle. In 1719, Ana de la Calle paid a notary in the northern Peruvian city of Trujillo to compose her will. She identified herself as a free morena of casta lucumí from the Yoruba-speaking interior of the Bight of Benin. Before deconstructing the terms “lucumí” and “morena” as used together by Ana de la Calle, this chapter first provides an overview of slavery and freedom in colonial Peru. It then considers lucumí as an elite status, as well as how Ana de la Calle's claim to be free and Lucumí made her unique and perhaps isolated her from other free women of color in colonial Trujillo. By analyzing why Ana de la Calle used morena and lucumí together, this chapter shows how casta terms were harnessed by both enslaved and free people of the African Diaspora.

Résumé :

Amyloidosis is a disorder of protein folding in which normally soluble plasma proteins are deposited in the extracellular space in an abnormal insoluble fibrillar form. The process of amyloid formation and deposition causes cytotoxicity and progressive organ dysfunction. Amyloid is remarkably diverse and can be hereditary or acquired, localized or systemic, and lethal or merely an incidental finding. The most important numerically are AL amyloidosis, in which the fibrils are composed of monoclonal immunoglobulin light chains, and AA amyloidosis, in which the acute phase reactant Serum Amyloid A component forms the fibrils.The kidney is involved in 75% of patients with systemic amyloidosis. Heavy proteinuria or nephrotic syndrome is characteristic of most amyloid variants.Without treatment, systemic disease is usually fatal but measures that reduce the supply of amyloid fibril precursor proteins can result in regression of amyloid deposits, prevention of organ failure, and improved quality of life and survival. Early diagnosis, before irreversible organ damage has occurred, is the key to effective treatment. Recent advances in diagnosis and therapy have much improved the outlook of patients with AL amyloidosis, but agents with broader promise are under investigation.

Résumé :

The chapter examines the relationships between Prokofiev’s early music and the poets that inspired him. Guided by Konstantin Balmont’s poetic characterization of him in the early 1920s as a “sun-sounding Scythian,” it looks at two specific facets of Russian Symbolism and post-Symbolism that informed Prokofiev’s works: the sun cult and Scythianism. Prokofiev’s luminous Scythianism encompasses the paradox of the lyricism of his early songs and the perceived barbarism of his rejected ballet Ala and Lolli, from which the composer derived his Scythian Suite. By analyzing Prokofiev’s collaboration with Gorodetskii on Ala and Lolli and the composer’s settings of Balmont’s and Akhmatova’s poems, we can understand how the incarnations of the sun god in the Russian Silver Age informed both the sunrise music and the aesthetics of horror in the ballet and the suite. The chapter also reflects on Ala and Lolli as an unrealized ballet in the shadow of Igor Stravinsky’s Rite of Spring.

Résumé :

The relationship between Ava and Pegu was a symbiotic dualism: of time, space and type. Ava was not only a reformulation of something old, and Pegu, the genesis of something new, but as one was located in the agrarian Dry Zone and the other, on the commercial coasts, each was historically, materially, and in terms of general character, distinct. Whereas the Kingdom of Ava was essentially the resurrection of an old kingdom—Pagan writ small—Pegu was a new kingdom composed of new leaders, people, and cultures. Ava was a familiar, Upper Myanmar polity: the same material environment and demographic base, the same economic, social and political institutions, the same language, writing system, cosmology, and culture. Pegu, on the other hand, was a new, independent kingdom of Lower Myanmar, led by newcomers (the Mon speakers) who had migrated from what later became Thailand. Yet, because both Ava and Pegu were built on the same foundations (Pagan), both had certain common elements. They shared virtually the same religion and thought systems; similar social customs, values, and mores; familiar political and administrative principles; a common, even if contested, history; and certainly the same writing system. Whatever the dissimilarities were, they did not produce a binary situation of two irreconcilably antagonistic ethnic entities—Burman and Mon as convention has it—rather, these dissimilarities created a dualism of geo-political and cultural differences whose energy and dynamism came from the tension created precisely by those differences. In fact, Ava and Pegu’s relationship not only epitomized Southeast Asia’s “upstream-downstream” paradigm common throughout much of its history, it continues today in Naypyidaw and Yangon.

Résumé :

As abelhas Apis mellifera produzem dois tipos de méis, os quais se distinguem conforme o tipo de fonte sacarínica utilizada: os méis florais, elaborados a partir do néctar de flores; e o mel de melato, produzido utilizando excreções de insetos sugadores de plantas e/ou secreções de plantas (EUROPEAN COMMISSION, 2002). Ambos os tipos de méis são apreciados por consumidores e indústrias alimentícias, farmacêuticas e de cosméticos, os quais encontram nos méis um alimento versátil com características sensoriais, físico-químicas, nutricionais e terapêuticas diversificadas. Por esses motivos, o mel é considerado um alimento funcional e o interesse no seu uso e consumo tem aumentado constantemente (PITA-CALVO; VÁZQUEZ, 2017; SERAGLIO et al., 2019). O mel é constituído principalmente pelos monossacarídeos, frutose e glicose, além da água. Mas também são encontrados centenas de outros compostos em menores concentrações, como os ácidos orgânicos alifáticos de baixa massa molar (AOA). Esses compostos são encontrados nos méis em concentrações em torno de 0,5 a 1% e são vinculados como os principais responsáveis pela acidez do mel. Os AOA podem ser oriundos da fonte sacarínica utilizada para a elaboração do mel, ou seja, do néctar, excreções e secreções açucaradas; do pólen, principal fonte protéica utilizada pelas abelhas; dos processos de elaboração e maturação do mel na colmeia; e das etapas pós-colheita do mel, que incluem o processamento e estocagem (BRUGNEROTTO et al., 2019; PITA-CALVO; VÁZQUEZ, 2017; SERAGLIO et al., 2019). Em méis florais, o pólen é comumente encontrado em concentrações maiores do que em méis de melato, sendo inclusive o material investigado na análise melissopalinológica para a indicação da origem botânica de méis florais (REYES; SANCHÉZ, 2017). Portanto, o pólen é um importante constituinte presente em méis, especialmente méis florais, podendo contribuir no perfil de AOA nesses produtos (KALAYCIOĞLU et al., 2017). Além disso, o pólen é outro produto apícola com valor agregado, sendo comercializado para consumo direto como pólen comercial bem como ingrediente em suplementos, por exemplo. Entretanto, informações relacionadas a composição de AOA no pólen são escassas. Nesse sentido, o presente estudo teve como objetivo investigar qualitativamente o perfil de AOA em pólen comercial do município de Urupema, Santa Catarina, Brasil, utilizando eletroforese capilar acoplada a detector de arranjo de diodos.

Résumé :

This chapter explores Gillian Whitehead’s Awa Herea. A personal and deeply felt response to the nature and folklore of New Zealand is always present in Whitehead’s music. The chapter illustrates how this is shown strongly in this cycle, for which she has composed her own text. Intimate spiritual identification with her heritage (she is one-eighth Maori) manifests itself, both in a special sensitivity to the sights and sounds of birds, beasts, plants, landscapes, and climate, and their significance in Maori culture, and in a fierce resistance to the commercial interests that threaten to destroy them. The work is divided into seven movements, some overlapping, making an exceptionally well-balanced whole.

Résumé :

This chapter, by Suzanne Conklin Akbari and Asa Simon Mittman, addresses the subject of cartography and medieval perceptions of geographical space, specifically in relation to Jerusalem. The chapter pays particularly attention to the map of the city in a manuscript from twelfth-century Flanders, doing so in the context of an overview of medieval map-making which stresses the symbolic function of maps within a Christian view of the physical world, with Jerusalem the ideal city at its centre. For the composer of the map examined here, however, Jerusalem is not just an ideal, but a real city. Thus theological understanding is strikingly combined with the practical knowledge.

Résumé :

Chapter Seven theorizes how Joseph Smith composed the Book of Mormon. Through a process of "revelatory translation," Smith spent several years crafting story outlines for the Book of Mormon, while simultaneously seeking spiritual confirmation of the historical authenticity of the narratives. Whether using a notebook of story outlines or simply his memory, Smith reviewed each of the story outlines prior to dictation, and then dictated the stories without the use of notes or manuscripts. The chapter contextualizes Smith's process within the western esoteric tradition of using seer stones and a biblical-style Urim and Thummim, with attention to the esotericism of John Dee and his scryer Edward Kelly (aka "Kelley"), who used a seer stone ("shew-stone") to translate angelic texts. The chapter further suggests the influence of biblical commentator Adam Clarke and his discussion of Paul's New Testament reference to the "tongue of angels." The chapter then reviews historical accounts by eyewitnesses to Smith's process of dictation and challenges apologetic interpretations. The chapter concludes with the theory that Smith composed the Book of Mormon by formulating the narratives in the work, after which he sought spiritual confirmation of their accuracy in a collaborative, spiritual co-authorship with the divine.

Résumé :

Composite materials have been explored in architecture for their high performance characteristics that allow customization of functional properties of lightness, strength, stiffness and fracture toughness. Particularly, engineering advancements and better understanding of fiber composites have resulted in growing applications for architectural structures and envelopes. As most new developments in material fabrication start outside the realm of architecture such as in automobile and aeronautical industries, there is need to advance knowledge in architectural design to take advantage of new fabrication technologies. The authors introduce results of new digitally driven fabrication methods for fiber-reinforced composite sandwich panels for complex shaped buildings. This presentation discussed the material properties, manufacturing methods and fabrication techniques needed to develop a proof of concept system using off-the-shelf production technology that ultimately can be packaged into a mobile containerized facility for on-site panel production. The researchers conducted experiments focusing on developing a digitally controlled deformable mold to create composite relief structures for highly customized geometrical façade components. Research findings of production materials, fabrication methods and assembly techniques, are discussed to offer insights into novel opportunities for architectural composite panel fabrication and commercialization.

Résumé :

This paper presents effective extensional stiffness of plain-weft knitted fabric reinforced composites obtained from finite element analysis and analytical calculations. For micro-mechanical analyses, a unit cell, enclosing the characteristic periodic repeat pattern in the knitted fabric, is isolated and modeled. Psuedo three-dimensional finite element model is constructed using laminated shell elements. Composite extensional stiffness is estimated for plane-stress and plane-strain conditions. Further, stiffness and compliance averaging methods have been used to determine the upper and lower limits of composite stiffness. The models are explicitly based on the properties of fiber and matrix materials and orientation of yarns. Results obtained from the models are compared with experimental values.
