▼ Alavancado pelo processo da globaliza??
o, a qualidade tornou-se fun??
o decisiva para a conquista de clientes e competitividade. Assim, as organiza??es est?
o evoluindo para
o aperfei?oamento de seus m?todos de gest?
o, com intuito de atender aos requisitos exigidos pelos clientes. Dentro do contexto da gest?
o da qualidade, um dos m?todos
mais difundidos ?
o Ciclo PDCA, que pode ser desdobrado dentro de cada processo da organiza??
o e para
o sistema de processos em sua totalidade. No setor de servi?os, a
percep??
o do cliente ? indispens?vel para altera??
o de diretriz de controle (melhorias). Para isto, a estat?stica pode ser utilizada para viabilizar a coleta,
o processamento e a
disposi??
o das informa??es, de forma que
o conhecimento gerado ? utilizado, por meio do Ciclo PDCA, para atingir metas de melhoria. Neste sentido,
o trabalho objetiva propor um modelo de infer?ncia estat?stica sobre a qualidade do processo de compra p?blica direta em Institui??
o de Ensino. Para isso, foi analisada a rotina do setor de compras, na qual se fez
o uso das ferramentas da qualidade e dos
testes n?
o
param?
tricos para fazer compara??es entre grupos de fatores. Com isso, foi poss?vel identificar os fatores que influenciam de forma significativa
o aumento do tempo dos processos. A abordagem da pesquisa ? qualitativa, principalmente na coleta e an?lise dos dados, e quantitativa no tratamento. Quanto aos fins, a natureza da pesquisa ? explorat?ria e descritiva e quanto aos meios de investiga??
o, um estudo de caso. Com
base no marco te?rico, foi poss?vel elaborar um modelo de procedimentos para execu??
o de uma experimenta??
o que envolve
o Ciclo PDCA, as ferramentas da qualidade e os
testes n?
o param?
tricos para infer?ncia estat?stica sobre a qualidade do processo. A partir da aplica??
o deste modelo, identificou-se que
o fator valor alto ?
o mais significativo no processo de compra p?blica direta. Fora este fator, a natureza do
processo classificada como material permanente e processos que tramitam por mais de dezesseis setores tamb?m s?
o fatores que influenciam no aumento do tempo. Dessa
forma, foi poss?vel contribuir com a ?rea de gest?
o da qualidade, visto que se delineou a respeito da infer?ncia estat?stica na qualidade em processos de compras, um assunto
pouco difundido no ?mbito do setor p?blico.

▼ Diplomamunkám sorá
n O,
N heterociklusok lágyionizációs módszerrel történő fragmentációját végeztem APCI körülmények között. A vizsgált anyag négy izomerjének fragmentációs útvonalait MS/MS és pszeudo MS3 mérésekkel térképeztem fel. Elkészítettem az egyik izomer részletes fragmentációs sémáját, és igazoltam a fragmensek szerkezetét. Kimutattam gyökionok képződését is az egyszeres töltésű protonált lezárt héjú kationok mellett. Vizsgáltam a különböző izomerek fragmentációjában való eltéréseket. Ehhez a másik három izomer spektrumait is felvettem. Az első két (1. és 2.) izomer eseté
n három fő fragmens képződik. NO2 vesztéssel keletkezik az A termékion, a 3, 4 és 6, 7 szénatomok közötti kötések hasadásával képződik a B, valamint az 5-ös nitrogé
n, 4-es szénatom és a 6, 7 szénatomok közötti kötések hasadásával alakul ki a C termékion. Az utóbbi két fragmens a krománt is tartalmazó molekularészek lehasadásával képződik. Ezeket pszeudo MS3 mérésben kiválasztottam és azonosítottam a spektrumokon megjelenő jelentősebb intenzitású csúcsokat.
Az MS/MS és MS3 tömegspektrumok tanulmányozásával megállapítottam, hogy az 1. és 2. izomer fragmentációs mechanizmusa megegyezik. Eltéréseket a 3. és 4. izomer eseté
n tapasztaltam. A 3. izomernél a 13-as C atom a 6-os C atom helyett a 4-eshez kötődik, a 4. izomernél pedig az 5-ös
N atom fel van cserélve 4-es C atommal. Igazoltam, hogy ezek a változások az izomereknél egymástól eltérő fragmentációt eredményeznek. Ennek eredményeként a 3. izomer eseté
n NO2 lehasadást nem tapasztaltam, csak nagy energiáknál. A 7-es és 8a valamint az 1-es
O és 2-es C atomok közötti kötések hasadása következményként kialakuló csúcs az első két izomer spektrumában gyakorlatilag meg sem jelenik. Hasonlóság a többi izomerrel, hogy az első jelentősebb intenzitású fragmens a 3. izomer eseté
n is .OH vesztéssel keletkezik. Megjelentek a többi izomerre jellemző fragmensek is, hasonló intenzitással.
A 4. izomer eseté
n ismét látható az NO2 vesztéssel képződő A fragmens. A 3. és 4. izomerekre egyaránt jellemző az m/z 215 csúcsot, valamint a 4. izomer eseté
n megjelenő m/z 355 csúcsot nem sikerült azonosítani. Ezek a szerkezetek valamilyen átrendeződés eredményeként jöhettek létre.
A négy izomer esetében az ütközési energia függvényében ábrázolva a disszociálatlan hányadot megállapítottam, hogy az izomerek fragmentációs stabilitása hasonló, az 1. és 2. izomer eseté
n pedig megegyező.
Ezen vegyületek származékai a jövőben esetleg orvosi szempontból is alkalmazhatóak lesznek különböző betegségek (például: Altzheimer-kór, Skizofrénia) kezelésére, így fontos, hogy ismerjük fragmentációs mechanizusukat.

Neste cen?rio este trabalho produziu uma solu??o s?lida nanoestruturada Sn(Se1?xSx) para x = 0, 0,24, 0,5, 0,76 e 1 utilizando a t?cnica Mecano-S?ntese. As amostras foram investigadas utilizando as t?cnicas de Difra??o de Raios X, M?todo de Rietveld, Calorimetria Diferencial de Varredura e Espectrometria Ultra Violeta e Vis?vel onde foi poss?vel constatar que as amostras se formaram com uma estrutura ortorr?mbica com microdeforma??o anisotr?pica de 4,9% em m?dia, e verificar que os picos do difratograma se deslocam para a direita ? medida que substitu?mos gradativamente sel?nio por enxofre na solu??o. As amostras se mostraram est?veis para temperaturas de at? 200?C e se desintegram para temperaturas acima de 600?C. Tamb?m foram observados gaps ?pticos de energia diretos e indiretos que mostraram valores diferentes da literatura e podem estar ligados ao m?todo utilizado para obter a absor??o de energia em que se utilizou a ?gua como solvente
para solubilizar com a amostra. Os valores obtidos do gap ?ptico de energia variam de 0,67 a 4,0 eV para o gap indireto e 4,1 a 5,4 eV para o gap direto.
SnX2 semiconductors (where X = Se, S, Te) have been extensively studied in recent years due to the variety of applications for electronic, optical and optoelectronic devices, as well as being a material of low toxicity, low cost, own layered structure and having the possibility to regulate the optical energy gap by modifying the proportion of the material stoichiometry. In this context, this study had produced a nanostructured solid solution Sn(Se1?xSx) to x = 0, 0,24, 0,5, 0,76 and 1 using the Mecano-Synthesis technique. The samples were investigated using X ray Diffraction, Rietveld Method, Differential Scanning Calorimetry and Ultraviolet-visible Spectrophotometry techniques which demonstrated that samples were formed with an orthorhombic structure with anisotropic microdeformation of 4,9%
on average. It was also possible to verify that the diffractogram peaks shift to the right as we gradually replace selenium with sulfur into the solution. The samples kept stable at temperatures up to 200?C and they disintegrated at temperatures above 600?C. Direct and indirect energy optical gaps were also observed from samples that showed different values from the literature and may be linked to two
main factors: 1) the method used to obtain the energy absorption in which water was used as a solvent to solubilize with the sample and 2) mass concentration of samples in solvent. The values gained from the optical energy gap range from 0,67 to 4,0 eV for indirect gap and 4,1 to 5,4 eV for direct gap.

▼ Research Doctorate - Doctor of Philosophy (PhD)
In spite of the highly fluctuating oil prices seen over the past number of years, the availability of relatively inexpensive sources of liquid hydrocarbons is diminishing, and the development of economically and environmentally viable alternative technologies to supply these hydrocarbons is vital. Projecting into the short and mid-term futures, the world economy is expected to continue to depend on hydrocarbon resources for stability, and thus technologies to produce these resources are important. Synthesis gas (CO and H₂), can be produced from a number of sources and feedstocks, such as biomass, waste and natural gas, and synthesis gas can be converted into liquid fuels such as hydrocarbons and alcohols, which are currently produced in large quantities in the conventional petrochemical industry. The selective oxidation of hydrocarbons, and in particular natural gas of which CH₄ the primary constituent, is notoriously difficult to control, mainly due to propensity of the reaction to generate to products of complete combustion. N₂O is a potent greenhouse gas (CO₂(e) = 300) and its concentration in the atmosphere is continuously increasing [Lee, Ryu et al, International Journal of Greenhouse Gas Control, January 2011, Pages 167–176]. Despite its greenhouse gas notoriety, N₂O is also recognised as a more selective oxidant than O₂ and has been used to selectively oxidise CH₄ to produce valuable products including synthesis gas. The production of synthesis gas, via its reaction with N₂O could be beneficial environmentally, as it could be used to provide valuable products when used to reaction with natural gas. The main aim of this research work is to investigate the scope of selective oxidation of natural gas (mainly CH₄) with N₂O over cobalt catalysts. The catalytic work was carried out in a continuous flow fixed bed micro reactor. Catalysts were prepared according to literature methods, as well as a new novel deposition method. The techniques used for catalyst characterization were powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), In situ Fourier transform infrared spectroscopy (FTIR), nitrogen adsorption/desorption isotherms, temperature program desorption (TPD), chemisorption, transmission electron microscopy (TEM). The elemental composition of catalyst samples was determined by using inductively coupled plasma optical emission spectrometer (ICP-OES). Based upon the experimental results obtained, the oxidation of CH₄ with N₂O over cobalt exchanged ZSM-5 (Co-ZSM-5) catalyst produced synthesis gas at a relatively high yield (19 %). When O₂ (instead of N₂O) was used as an oxidant over Co-ZSM-5 catalyst, synthesis gas was not formed. Similarly, when CH₄ and N₂O reacted over a cobalt on alumina catalyst, synthesis gas was not produced. Interestingly, H₂ was not detected as a reaction product when CH₄ with N₂O reacted over a Fe-ZSM-5 catalyst and only COx and H₂O were formed. The effect of the molar feed ratio (N₂O/CH₄ = 1, 3, and 5) was…

▼ A tecnologia associada à modificaçã
o da liberaçã
o de fármacos sofreu um incremento notório nas últimas décadas na tentativa de maximizar as vantagens inerentes às formas farmacêuticas de liberaçã
o controlada. A utilizaçã
o de sistemas matriciais constituídos por diversos tipos de polímeros é considerada uma opçã
o interessante, devido às vantagens desses sistemas. A quitosana (Qts) (poli – (1-4)Dglucosamina) é um polissacarídeo catiônico derivado da quitina, de fácil obtençã
o e com muitas aplicações industriais. Neste trabalho,
o derivado OCarboximetilquitosana (
O-CMQts) foi hidrofobicamente modificado com cloreto de lauroíla em diferentes concentrações, para obter um derivado da Qts com caráter anfifílico,
o O-Carboximetilquitosana-
N-Lauril (
O-CMQts-
N-Lauril), com diferentes graus de substituiçã
o (GS) e utilizá-lo como matriz na preparaçã
o de comprimidos de triancinolana (TC). A estrutura química dos derivados foi confirmada através das técnicas de espectroscopia no infravermelho (IV).
O grau de carboximetilaçã
o (GC) da
O-CMQts foi determinado através da titulaçã
o condutimétrica. Para determinar
o GS foi desenvolvido um método utilizando a espectroscopia no IV. A interaçã
o entre
o fármaco e
o polímero foi verificada de forma indireta através da quantificaçã
o do fármaco livre na dispersã
o polimérica. As propriedades tecnológicas dos derivados foram determinadas com
o objetivo de preparar comprimidos contendo
o fármaco através da compressã
o direta. Na preparaçã
o dos comprimidos, a TC foi incorporada à matriz dos derivados através da mistura física (MFT) e co-secagem fármaco: polímero por nebulizaçã
o (SDT). Os comprimidos foram caracterizados em relaçã
o a morfologia, absorçã
o de água e perfil de liberaçã
o do fármaco em meio gástrico simulado. Os derivados AC1 e AC2 apresentaram GS com valores entre 43,5 e 8,56 %. A quantidade de TC complexada aos derivados
N-acilados foi proporcional ao GS destes derivados.
O tamanho e a morfologia das partículas dos derivados
N-acilados foram influênciados pelo processo de obtençã
o e GS dos derivados. Os comprimidos SDT apresentaram resistência física maior quando comparado com os MFT, sendo que em ambos a resistência aumentou com
o GS do derivado. Os comprimidos apresentaram tempo de desintegraçã
o menor do que 15 min, exceto os comprimidos AC3T contendo 4 mg, que nã
o desintegraram em 300 min de análise. Nos comprimidos MFT (20 mg) a liberaçã
o máxima ocorreu em torno de 60 min, entretanto, a solubilidade do TC aumentou significativamente nos comprimidos preparados com derivados contendo GS elevado. Nos comprimidos SDT (20 mg) a proporçã
o de fármaco liberada por tempo foi dependente do derivado. Os comprimidos SDAC3T liberaram praticamente todo fármaco em 30 min, enquanto que os comprimidos SDAC1T liberaram cerca 16 % do fármaco no mesmo período de tempo. Os comprimidos contendo 4 mg de fármaco apresentaram liberaçã
o máxima em torno de 60 min, com exceçã
o dos comprimidos AC3T que liberaram cerca de 20 % de fármaco no mesmo intervalo de tempo. A partir dos resultados mostrados neste…

▼ The goal of the work was to evaluate
conjugation of chitosan and its N-succinyl and O-carboxymethyl
derivatives with particular first and second line antitubercular
drugs and effect of phosphorylation for final products solubility.
Carbodiimide (EDC) was chosen to catalyze amide bond formation
between reactive materials. Firstly, water soluble N-succinyl and
O-carboxymethyl chitosan derivatives were prepared using low
molecular weight chitosan (Sigma-Aldrich). After that, these
derivatives were conjugated with low molecular weight
antitubercular drugs: isoniazid, para-amino-salicylic acid,
pyrazinecarboxamide, ethionamide and cycloserine. Acetylation of
quinolones was prepared in order to protect active amino group of
piperazine to act in conjugation. Non-modificated chitosan was
conjugated with acetylated quinolones- ciprofloxacin, enoxacin,
norfloxacin, lomefloxacin, sparfloxacin and non-acetylated
quinolones- ofloxacin and levofloxacin. Solubility in water of
final products was increased by phoshorylation. Phosphorylated
O-carboxymethyl chitosan derivatives with para-amino-salicylic
acid, pyrazinecarboxamide and ethionamide were completely soluble.
Analysis of infrared spectroscopy and melting point (for acetylated
quinolones) confirmed that reactions of acetylation and conjugation
were performed successfully.
Darbo tikslas buvo įvertinti chitosano ir jo
N-sukcinil bei O-karboksimetil darinių konjugaciją su tam tikrais
pirmos ir antros eilės antituberkulioziniais vaistais bei
fosforilinimo įtaką galutinių produktų tirpumui. Karbodiimidas
(EDC) buvo panaudotas katalizuoti amidinės jungties susidarymą tarp
reaguojančių medžiagų. Pirmiausiai, iš mažos molekulinės masės
chitosano (Sigma-Aldrich) buvo susintetinti vandenyje tirpesni jo
dariniai: N-sukcinil chitosanas ir O-karboksimetil chitosanas. Šie
dariniai buvo sujungti su mažos molekulinės masės
antituberkulioziniais vaistais: izoniazidu, para-amino-saliciline
rūgštimi, pirazinkarboksamidu, etionamidu ir cikloserinu. Chinolonų
piperazino žiedo amino grupė buvo acetilinta tam, kad apsaugoti ją
nuo dalyvavimo konjugacijos procese. Nemodifikuotas chitosanas buvo
sujungtas su acetilintais chinolonais- ciprofloksacinu, enoksacinu,
norfloksacinu, lomefloksacinu, sparfloksacinu ir neacetilintais
chinolonais- ofloksacinu, levofloksacinu. Fosforilinimas buvo
atliktas tam, kad padidinti konjugacijos produktų tirpumą
vandenyje. Fosforilinti O-karboksimetil chitosano dariniai su
para-amino-saliciline rūgštimi, pirazinkarboksamidu ir etionamidu
buvo visiškai tirpūs vandenyje. Infraraudonosios spektroskopijos ir
lydymosi temperatūros (acetilintiems kvinolonams) analizės
patvirtino, kad acetilinimo ir konjugacijos reakcijos buvo atliktos
sėkmingai.

▼ Cette thèse porte sur des limites de grandes cartes à bord aléatoires. Dans un premier temps, nous nous intéressons aux propriétés géométriques de telles cartes. Nous montrons d'abord des résultats concernant les limites d'échelle et les limites locales du bord de cartes de Boltzmann dont le périmètre tend vers l'infini, que nous appliquons à l'étude du modèle O(n) rigide sur les quadrangulations. Ensuite, nous introduisons une famille de quadrangulations du demi-plan aléatoires avec un paramètre de torsion, dont on étudie les limites d'échelle et la structure de branchement. Enfin, nous établissons une propriété de confluence des géodésiques dans les cartes uniformes infinies du demi-plan, qui sont des limites locales de triangulations et quadrangulations à bord uniformes.Dans un second temps, nous considérons des modèles de percolation de Bernoulli sur les cartes uniformes infinies du demi-plan. Nous calculons le seuil de percolation par site critique pour les quadrangulations, et établissons une propriété d'universalité de ces modèles de percolation au point critique à partir des probabilités de croisement. Pour finir, nous étudions la limite locale de grands amas de percolation critiques en construisant l'amas critique émergent, une triangulation uniforme infinie du demi-plan munie d'un amas de percolation critique infini.
This thesis deals with limits of large random planar maps with a boundary. First, we are interested in geometric properties of such maps. We prove scaling and local limit results for the boundary of Boltzmann maps whose perimeter goes to infinity, which we apply to the study of the rigid O(n) loop model on quadrangulations. Next, we introduce a family of random half-planar quadrangulations with a skewness parameter, and study their scaling limits and branching structure. Finally, we establish a confluence property of geodesics in uniform infinite half-planar maps, which are local limits of uniform triangulations and quadrangulations with a boundary.Second, we consider Bernoulli percolation models on uniform infinite half-planar maps. We compute the critical site percolation threshold for quadrangulations, and prove a universality property of these percolation models at criticality involving crossing probabilities. To conclude, we study the local limit of large critical percolation clusters by defining the incipient infinite cluster, a uniform infinite half-planar triangulation equipped with an infinite critical percolation cluster.

▼ L’intérêt des peptides comme des médicaments potentiels est en constante augmentation. Des stratégies ont été développées pour améliorer la sélectivité, l’activité, et la stabilité des peptides vis-à-vis de la protéolyse. Dans ce mémoire de thèse, deux nouvelles modifications de peptides sont proposées.Dans le premier chapitre, nous présentons une nouvelle application de la réaction de transfert O-N acylique pour la synthèse de peptides agrafés (ou ‘stapled peptides’). L’introduction d’une ‘agrafe’ dans un peptide est un moyen de stabiliser une structure secondaire hélicoïdale en établissant un pont entre les résidus appropriés des chaînes latérales. Dans notre cas, l'agrafe est formée par un O-acyl isodipeptide. La liaison ester peut être convertie en liaison amide par un transfert O-N acylique. Cette stratégie permet une amélioration de la solubilité d’un peptide hydrophobe agrafé, avant son réarrangement à pH neutre.Dans le dernier chapitre, nous avons développé une méthodologie nouvelle pour la dimérisation de peptides non protégés. Cette méthode repose sur la formation de liaisons siloxane entre des peptides hybrides portant chacun un groupement dimethylchlorosilane. Nous avons ainsi dimérisé une séquence dérivée de la protéine p53, impliquée dans l’apoptose. A titre de comparaison, cette même séquence a été dimérisée en utilisant la cycloaddition d’Huisgen entre deux peptides modifiés possédant un azoture ou un alcyne en position N-terminale. Enfin, plusieurs dimères de la séquence du GHRP-6 (growth hormone releasing peptide) ont été synthétisés, avec des bras dimethylhydroxysilane placés à différentes positions. L’homodimérisation a été effectuée dans l'eau à pH neutre.
The interest in peptides as potential drug candidates was revived and is increasing constantly. Strategies have been developed to improve their selectivity and activity, and their stability toward proteolysis. In this thesis, two new peptide modifications are proposed.In the first chapter, we present a new application of the O-N acyl transfer reaction for the synthesis of stapled peptides. Peptide ‘stapling’ is a way of stabilizing secondary helical structure by establishment of a bridge between the side chains of suitable residues. In our case, the staple is formed by an O-acyl isopeptide which can be converted into amide bond by acyl migration. This strategy allows an improved solubility of the stapled hydrophobic peptide prior to rearrangement at neutral pH.In the last chapter, we developed also a new methodology for the dimerization of unprotected peptides. This method is based on siloxane bond formation between hybrid dimethylhydroxysilane peptides. A peptide derived from the tumor suppressor protein p53 was dimerized in water, at neutral pH using this methodology. The method was compared with the homodimerization carried out by Cu(I) azide-alkyne cycloaddition (CuAAC). For that purpose, p53 peptide derivative was synthesized with azide and alkyne linkers at the N-terminus. At last, several homodimers of growth hormone releasing…

▼ In this thesis, we study various conformal field theories in two different approximation schemes - the epsilon-expansion in dimensional continuation, and the large
N expansion. We first propose a cubic theory in d=6-epsilon as the UV completion of the quartic scalar
O(
N) theory in d>4. We study this theory to three-loop order and show that various operator dimensions are consistent with large-
N results. This theory possesses an IR stable fixed point at real couplings for
N>1038, suggesting the existence of a perturbatively unitary interacting
O(
N) symmetric CFT in d=5. Extending this model to Sp(
N) symmetric theories, we find an interacting non-unitary CFT in d=5. For the special case of Sp(2), the IR fixed point possesses an enhanced symmetry given by the supergroup OSp(1|2). We also observe that various operator dimensions of the Sp(2) theory match those from the 0-state Potts model. We provide a graph theoretic proof showing that the zero, two, and three-point functions in the Sp(2) model and the 0-state Potts model indeed match to all orders in perturbation theory, strongly suggesting their equivalence. We then study two fermionic theories in d=2+epsilon - the Gross-Neveu model and the Nambu-Jona-Lasinio model, together with their UV completions in d=4-epsilon given by the Gross-Neveu-Yukawa and the Nambu-Jona-Lasinio-Yukawa theories. We compute their sphere free energy and certain operator dimensions, passing all checks against large-
N results. We use two sided Pad\'e approximations with our epsilon expansion results to obtain estimates of various quantities in the physical dimension d=3. Finally, we provide evidence that the
N=1 Gross-Neveu-Yukawa model which contains a 2-component Majorana fermion, and the
N=2 Nambu-Jona-Lasinion-Yukawa model which contains a 2-component Dirac fermion, both have emergent supersymmetry.

▼ In this work the coordination modes of O,O- and N,O-donor complexing agents have been studied. Trichlorobis(triphenylphosphine)oxorhenium(V), [ReOCl3(PPh3)2], and tribromobis(triphenylphosphine)oxorhenium(V), [ReOBr3(PPh3)2], were used as starting materials to obtain eight rhenium(V) complexes. The precursor tetrabutylammonium tetrachlorooxorhenate(V), [NBu4][ReOCl4], was used to prepare an additional rhenium(V) complex. All the rhenium complexes presented here were obtained in good yield, being all of the hexacoordenated type [ReOX2L(PPh3)] (X = Cl or Br and L- = monocharged bidentated ligand). The complexes were characterized by infrared absorption spectroscopy, melting point, elemental analyses (CHN), nuclear magnetic resonance spectroscopy (31P{1H}, 1H and, in some cases, also 13C) and had their crystalline and molecular structures determined by X-ray diffraction on single crystals.
Neste trabalho foram estudadas as formas de coordenação de agentes complexantes O,O- e N,O-doadores, ao centro metálico de Re(V). Os complexos triclorobis(trifenilfosfina)oxorrênio(V), [ReOCl3(PPh3)2], e tribromobis(trifenilfosfina)oxorrênio(V), [ReOBr3(PPh3)2], foram utilizados como materiais de partida para a obtenção de oito complexos de rênio. O precursor tetraclorooxorenato(V) de tetrabutilamônio, [NBu4][ReOCl4], foi utilizado na síntese de um complexo de rênio adicional. Todos os complexos de rênio(V) aqui apresentados foram obtidos com elevado rendimento, hexacoordenados do tipo [ReOX2L(PPh3)] (X = Cl ou Br e L- = ligante bidentado monoaniônico). Os complexos com kojato e picolinato apresentam ligações de hidrogênio intermoleculares. Todos os complexos descritos neste trabalho foram caracterizados por espectroscopia de absorção na região do infravermelho, ponto de fusão, análise elementar (CHN), espectroscopia de ressonância magnética nuclear (31P{1H}, 1H e, em alguns casos, também de 13C) e tiveram suas estruturas cristalinas e moleculares determinadas por difração de raios X em monocristal.

▼ A qualidade desde o surgimento da globaliza??o tornou-se uma das palavras-chave mais difundidas junto ? sociedade. No setor p?blico sua concep??o est? associada ? rapidez, confiabilidade, precis?o e seguran?a, contudo, a percep??o que os indiv?duos t?m sobre a presta??o de servi?os p?blicos no Brasil, n?o condiz com estes adjetivos de qualidade. A literatura aponta diversas ferramentas capazes de avaliar e melhorar a qualidade em servi?os, entretanto predominam-se mecanismos subjetivos, que se resumem a mensurar a satisfa??o do cliente. ? certo que, a qualidade tem foco no cliente, mas na atual Era da Qualidade assume-se que ela ? gerada no processo produtivo. Considerando esta lacuna, surgiu o questionamento: de que forma pode-se otimizar processos do setor de servi?o, mantendo o foco na melhoria da qualidade, em especial os processos executados no setor p?blico de ensino? Para responder tal pergunta, adaptou-se um modelo de an?lise e melhoria de processos, atrav?s da concatena??o das fases do M?todo de An?lise e Solu??o
de Problemas (MASP) com as etapas de Planejamento Experimental. Aplicou-se o modelo proposto na Coordena??o de Integra??o Empresa-Escola (CIE-E) do IFAM Campus Manaus Centro, avaliando 397 registros de est?gios finalizados no ano de 2012, onde o tempo de dura??o do processo foi apontado como o vil?o. Deste modo, desenvolveu-se uma pesquisa experimental caracterizada como explorat?ria
e descritiva, de natureza aplicada e abordagem qualitativa e quantitativa. Fez-se uso das Ferramentas da Qualidade para a coleta e disposi??o dos dados, como tamb?m de Testes N?o Param?tricos para a an?lise dos dados. Ao fim, respaldado em
crit?rios de qualidade e estat?stico, identificou-se que a combina??o carga hor?ria alta e n?o experi?ncia trabalhista constitu?a a combina??o ideal dos fatores control?veis que interferiam nos registros de est?gio estudados, resultando no
menor tempo do processo, ou seja, determinou-se a regi?o ?tima. Assim, com esse estudo, pode-se avaliar o procedimento de implanta??o de t?cnicas estat?sticas no
setor de servi?o para a otimiza??o e melhoria de seus processos.
The quality since the advent of globalization has become one of the keywords most widespread in society. In the public sector is associated to the rapidity, reliability, precision and security, however, the general perception that the individuals have on the provision of public services in Brazil is not consistent with these adjectives quality. The literature suggests several tools to evaluate and improve the quality in
services, but is subjective mechanisms predominate, which are summed to measure customer satisfaction. Admittedly, the quality has focused on the customer, but in the current Era of Quality is assumed that it is generated in the production process. Considering this gap, the question arose: how to optimize processes of the service sector, while focusing on quality improvement, especially processes executed in the public sector of education? To answer this question, it was adapted a model of analysis…

▼ Les OBP sont des petites protéines solubles qui se lient avec des molécules odorantes et phéromonales. Le rôle des OBPs n’est pas complètement compris. Une hypothèse suggère que l’OBP solubilise et transporte les ligands aux récepteurs olfactifs et la liaison entre les molécules odorantes et l’OBP est non spécifique. Une autre hypothèse suggère que le complexe formé est une liaison spécifique entre une molécule odorante donnée et une OBP spécifique. Ce travail de thèse montre que les OBPs sont impliquées dans la première étape de la discrimination des odeurs. Dans un premier temps, nous avons montré l’implication de la Phe35 et la Tyr 82 dans la sortie du ligand par l’OBP. Dans un second temps, nous avons mis en évidence la présence de différentes isoformes d’OBP et de VEG qui diffèrent par les modifications post-traductionnelles (phosphorylation et GlcNAcylation) a la fois sur les protéines natives extraites de la muqueuse respiratoire et sur les protéines recombinantes produites par P.pastoris et CHO. Ces isoformes sont capables de discriminer des molécules odorantes et phéromonales. Les OBPs ne sont pas des transporteurs passifs car elles assurent un fin codage des molécules odorantes ou phéromonales avant l’interaction de ce complexe avec un récepteur spécifique.
OBPs are small soluble proteins that bind with odorant molecules and pheromones. The role of OBP is not completely understood. A hypothesis suggests that OBP solubilize and transport the ligands to olfactory receptors and the binding between odorant molecule and OBP is unspecific. An other hypothesis suggest that the complex formed is the specific binding between a given odorant molecule and a specific OBP. This work of thesis show that OBP are involved in the first step of odorant discrimination. Initially, we have showed the involvement of the Phe35 and Tyr 82 in the uptake of ligands by OBP. Second, we have given rise to the presence of various isoform of OBP and VEG that differ by post-translational modifications (phosphorylation and GlcNAcylation) both on natives proteins extract of respiratory mucosa and on recombinants proteins produce by P. pastoris and CHO. These isoforms are able to discriminate of odorant molecules and pheromones. OBPs are not passives carriers because they ensure a fine coding of odorant molecules and pheromones before interaction of this complex with specific receptor.

▼ Oxygen and Nitrogen containing compounds are of utmost importance due to their interesting and diverse biological activities. The construction of the C-O and C–N bonds is of significance as it opens avenues for the introduction of ether and amine linkages in organic molecules. Despite significant advancements in this field, the construction of C-O and C–N bonds is still a major challenge for organic chemists, due to the involvement of harsh reaction conditions or the use of expensive catalysts or ligands in many cases. Thus, it is a challenge to develop alternative, milder, cheaper and more reproducible methodologies for the construction of these types of bonds. Herein, we introduce a new efficient ligand free catalytic system for C-O and C-N bond formation reactions.

▼ Bacteria have the natural ability to install protective post-synthetic modifications onto its bacterial peptidoglycan (PG); the coat that is woven into bacterial cell wall. Peptidoglycan
O-acetyltransferase B (PatB) catalyzes the
O-acetylation of peptidoglycan in Gram (–) bacteria, which aids in bacterial survival, as it prevents autolysins such as lysozyme from cleaving the peptidoglycan at the β-1,4-glycosidic bond between
N-acetylmuramic acid (NAM) and
N-acetylglucosamine (NAG). In this dissertation, the substrate promiscuity and mechanistic details of PatB’s acetylation function was explored and it was determined that PatB has substrate tolerance for bioorthgonal short
N-acetylcysteamine (SNAc) donors. Exploiting this lax specificity, a variety of functionality including azides and alkynes were installed on tri-
N-acetylglucosamine (NAG)3, a peptidoglycan mimic, as well as peptidoglycan isolated from various Gram (+) (Bacillus subtilis) and Gram (–) (Escherichia coli, Vibrio parahaemolyticus, and Pseudomonas putida) bacterial species. The bioorthogonal modifications were shown to protect the isolated peptidoglycan against lysozyme degradation in vitro. We further demonstrate that this post-synthetic modification of peptidoglycan can be extended to use click chemistry to fluorescently label the carbohydrate backbone of mature peptidoglycan in whole bacterial cells of Bacillus subtilis. Modifying peptidoglycan post-synthetically can aid in the development of antibiotics and immune modulators by expanding on the current understanding of how the bacterial peptidoglycan is processed by lytic enzymes presented in the innate immune system.

▼ Isocyanates are invaluable bulk chemicals that play a central role in the synthesis of various polymers and provide a key platform for the synthesis of nitrogen-containing molecules such as carbamates and ureas. Unfortunately, isocyanates suffer from high toxicity, low functional group tolerance, and a propensity to undergo deleterious side-reactions. Consequently, blocked (masked) isocyanate derivatives have been the subject of increased interest resulting from their reduced toxicity and exceptional control over isocyanate reactivity. This strategy has largely been relegated to the polymerization literature, although its use in the synthesis of complex urea and carbamate derivatives is well established in synthetic organic chemistry.
However, prominent gaps in the blocked isocyanate literature were clear at the outset of this research project. First and foremost, the development of heteroatom-substituted isocyanates, such as N- and O-substituted derivatives, remained relatively scarce despite their potential for the synthesis of important nitrogen-containing derivatives. Furthermore, the additions of carbon-centred nucleophiles on blocked N-, O-, and even C-substituted blocked isocyanates were exceedingly rare. Finally, the use of a blocking group strategy in catalytic transformations of isocyanates remained largely absent from the literature. This was particularly striking given the widespread development of catalytic transformations of isocyanates.
As such research efforts began focusing on furthering the development of blocked N-isocyanates as a vital platform for heterocyclic synthesis (chapter 2). Initially, the cascade reactivity of blocked N-iso(thio)cyanates was expanded to incorporate electrophiles such as alkynes (section 2.2). This readily provided access to imidazolone and thiazolidine products. Subsequently, the development of a cascade reaction providing access to 1,2,4-triazin-3(2H)-ones was explored (section 2.3). This provided the first examples of an N-isocyanate cascade which hinged on the use of acid catalysis. Moreover, insight into hydrazone isomerization was gained. Finally, these efforts culminated in the development of cascade reactions providing access to a rare class of 1,2,4-triazinones as well as 5-aminopyridazinones (section 2.4). This provided the first example of a cascade reaction involving a C-C bond formation onto a blocked N-isocyanate derivatives. Furthermore, this development was pivotal in re-focusing attention on the development of general strategies to achieve addition of carbon nucleophiles onto blocked isocyanate derivatives.
Towards this end, the development of two strategies to achieve carbon-centred nucleophilic additions on both blocked N- And O-isocyanates were developed (chapter 3). Inspiration from the isocyanate literature led to the development of carboxylic acids as formal carbon nucleophiles (section 3.2). This strategy was found to be quite general for the synthesis of hydroxamates from blocked O-isocyanates. Furthermore, encouraging results were generated…

▼ A parte de los artículos, esta memoria consta de cinco partes más: una introducció
n bibliográfica, unos objetivos, un capítulo de resultados y discusió
n, unas conclusiones y, por último, un compendio de todas las referencias bibliográficas consultadas para la elaboració
n de este trabajo. El grupo de investigació
n al que pertenezco comenzó los estudios de ligandos derivados del pirazol a principios de los años 90. Desde entonces, no se han parado las investigaciones, dando lugar a la síntesis de nuevos ligandos pirazólicos 3,5- disubstituidos potencialmente di-, tri- y tetradentados. En un principio se ensayó la reactividad de estos ligandos con metales de la primera serie de transició
n [Mn(II), Fe(III), Co(II), Ni(II), Cu(II)], obteniendo una gran diversidad estructural. En los últimos años se ha ampliado el número de ligandos y el número de complejos, utilizando metales de la segunda y tercera serie de transició
n [Pd(II) y Pt(II)]. Siguiendo con el estudio de ligandos derivados del pirazol, se abre una nueva línea de investigació
n dentro del grupo, basada en la síntesis y estudio de la química de coordinació
n de los ligandos pirazólicos substituidos en la posició
n 1 por grupos amina, fosfina, fosfinito, alcohol, éter, tiol, tioéter y tioéter-alcohol. Los metáles utilizados son básicamente de la segunda y tercera serie de transició
n [Ru(II), Rh(I), Pd(II) y Pt(II)]. Dentro de esta línea de investigació
n es donde está enmarcada esta Tesis que lleva por título: "Síntesis y caracterizació

▼ Protein glycosylation with
O-linked
N-Acetylglucosamine (
O-GlcNAc) is a post-translational modification of serine and threonine residues in nucleocytoplasmic proteins. Alterations in the glycosylation pattern of
O-GlcNAc has been shown to play a role in many different cellular processes and
O-GlcNAcylation is often found at sites that are also known to be phosphorylated. Unlike phosphorylation, the addition and removal
O-GlcNAc are regulated by only two enzymes,
O-GlcNAc transferase (OGT) and
O-GlcNAc hydrolase (
O-GlcNAcase or OGA). So far, no obvious consensus sequence has been found for sites of
O-GlcNAcylation; additionally,
O-GlcNAcase acts on all
O-GlcNAcylated proteins, seemingly independent of their sequence. Despite the importance of this modification, very little is known about the structural relationship between these enzymes and their substrates. Nor is it clear, how only a single hydrolase is capable of removing
O-GlcNAc from all GlcNAcylated proteins, independent of the protein sequence.
Here a combination of computational and experimental techniques is employed to develop an understanding of the interactions between an inactive point mutant of OGA and its substrate, in an aim to designing an OGA-based receptor with enhanced affinity for
O-GlcNAc. The key interactions involved in binding have been identified computationally, and are separated into residues which are directly responsible for the specificity of the complex (hot residues) and those whose mutation may increase the affinity (tepid residues). An inactive human OGA, which was engineered using site directed mutagenesis to knock out the nucleophile, was used to construct a combinatorial library in bacteriophage by saturation mutagenesis of the tepid residues. This library has been screened leading to the discovery of a single clone showing high affinity and specificity for
O-GlcNAc. Reagents of this type are termed Lectenz®, and may be important diagnostic tools for the detection of enzyme substrates, such as
O-GlcNAcylated proteins.
In addition, five models of
O-GlcNAcylated peptides in complex with a bacterial OGA were generated and assessed in terms of conformational dynamics and binding contributions in an aim to understand how OGA recognizes
O-GlcNAc in situ. The results show that each of the five glycopeptides bind to OGA in a similar fashion, forming OGA-peptide interactions primarily, but not exclusively, with peptide backbone atoms, thus explaining the lack of sensitivity to peptide sequence. Nonetheless, differences in peptide sequences, particularly at the -1 to -4 positions, lead to variations in predicted affinity, consistent with observed experimental variations in enzyme kinetics. The potential exists therefore to employ the present analysis to guide the development glycopeptide-specific inhibitors, or conversely, the conversion of OGA into reagents that could target specific
O-GlcNAcylated peptide sequences.

▼ Este trabalho teve como objetivo verificar se
o tema Educa??
o Especial tem se efetivado no Projeto Pedag?gico do Curso de Filosofia da Universidade Federal do Amazonas (UFAM), comparando com outras Universidades Federais da regi?
o norte com intuito de compreender como a UFAM tem constru?do
o PPC de Filosofia para atender ? forma??
o inicial de professores de Filosofia sobre a educa??
o inclusiva, a fim de terem, ao final da licenciatura, uma forma??
o que, de fato, os possibilite
o atendimento aos alunos com qualquer tipo de necessidade especial.
O movimento da educa??
o inclusiva via Educa??
o Especial tem sido
o centro das discuss?es nas agendas das pol?ticas p?blicas educacionais no Brasil e no mundo e que, desde as d?cadas de 1990 e 1994, respectivamente com as Declara??es de Jomtien ? que trata sobre Educa??
o para Todos e da Salamanca ? que aborda a Educa??
o Especial na perspectiva da inclus?
o,
o Estado vem assumindo
o compromisso de promover
o acesso das pessoas com defici?ncia na Educa??
o B?sica e garantir a perman?ncia delas no processo educacional, pois sabemos que a Educa??
o Especial no processo de forma??
o inicial tem sido um dos desafios para
o sucesso da implementa??
o da pol?tica de Educa??
o inclusiva. Para a realiza??
o da pesquisa, a metodologia foi assim definida: quanto aos objetivos, ? explorat?ria, quanto ? abordagem, ? qualitativa; quanto ao m?todo de abordagem, utilizou-se
o hermen?utico-dial?tico e, quanto ao m?todo de procedimento,
o bibliogr?fico,
o documental e
o comparativo, sendo
o corpus de estudo composto pelo PPC da UFAM, pelo PPC da UFAC e leis brasileiras sobre Educa??
o Especial. Optamos pelo m?todo hermen?utico-dial?tico por nos permitir
o aprofundamento da compreens?
o e da interpreta??
o dos marcos legais e das literaturas que tratam da Educa??
o Especial na perspectiva da inclus?
o e da forma??
o de professores em Filosofia.
O respectivo estudo nos apontou que, mesmo com os marcos legais sobre a Educa??
o Especial na perspectiva da inclus?
o escolar, a matriz curricular de Filosofia da UFAM, em parte,
n?
o tem acompanhado as mudan?as das Leis de inclus?
o, dando aten??
o somente para uma parcela do p?blico-alvo da Educa??
o Especial, que s?

▼ Studien undersöker invånare och verksammas upplevelser av ett, enligt en rapport frånunderrättelseenheten, utsatt bostadsområde i Västerås. För att besvara frågeställningen har vigenomfört 14 intervjuer varav 5 var semistrukturerade och resterande var ostrukturerade. Vihar även genomfört 6 observationer, där samtliga var icke deltagande observationer. Dåmålsättningen var att undersöka så förutsättningslöst som möjligt har vi använt oss av BarneyGlasers variant av grundad teori som metodologiskt angreppssätt. Tidigare forskning som vibelyser är delade i tre teman: Segregation, familjestrukturer och sysselsättning. En teorisom är grundad i data presenteras i resultatdelen och beskriver det som sker i Bäckby.Studiens teoretiska referensramar är Erving Goffmans teori om stigma, Howard. S. Beckersteori om avvikande samt Giorgio Agambens teori om undantag och belägring som fungerarsom en komplettering till förståelsen av hur det är i ett utsatt bostadsområde. Slutsatsernavisar att det är en handfull ungdomar som står för oron som sker i Bäckby och dess handlingarmöjliggörs på grund av misslyckade strukturella åtgärder. De förhållanden vi har funnitavgörande för trygghets upplevelse i Bäckby är inte endast att ungdomar behöversysselsättning, utan det behövs även en spridning av människor med utländsk bakgrund blandetniska svenskar och förebyggande åtgärder från externa aktörer.

▼ H? pelo menos 35 anos a composi??o Argumento tornou-se uma das mais conhecidas obras do cancioneiro amazonense pelo nome de N?o mate a mata, desde que recebeu seu primeiro registro fonogr?fico no LP Compacto Simples Adelson (1980) e passou ser tocada nas principais r?dios amazonenses. De autoria do cantautor manauara Adelson Santos, a obra ? reconhecida por artistas e apreciadores da m?sica local como uma verdadeira ode ? conserva??o ambiental na Amaz?nia. A can??o atingiu reconhecimento social apenas em 1980, posicionando Adelson Santos como o mais representativo ?cantautor ecol?gico? amazonense. O contexto sociocultural no qual este artista come?ou a refletir sobre a problem?tica ambiental por meio de sua m?sica, esteve marcado por uma s?rie de eventos importantes para a consolida??o do Movimento Ecol?gico em todo o mundo. Em seus mais de 40 anos de cria??o, a referida pe?a musical tem demonstrado seu car?ter precursor e atemporal, metamorfoseando-se em arranjos desde o Boi-bumb? ao Jazz instrumental, de releituras de realizadas por artistas de diversas gera??es e segmentos musicais distintos no Estado do Amazonas. Com a realiza??o deste estudo, objetivamos muito mais do que realizar apenas um invent?rio das can??es ecol?gicas de Adelson Santos, analisar sob a perspectiva da etnomusicologia e da antropologia da performance musical sua mais importante obra Argumento, ou simplesmente, reconstruir tra?os configurativos de sua biografia para comprovar a sua condi??o de sujeito ecol?gico. A cr?tica radical ? crise ambiental contida na obra de Adelson Santos ? vista por n?s como mais uma possibilidade para reafirmar a posi??o de centralidade da Cultura na discuss?o sobre o Desenvolvimento Sustent?vel em todo o mundo no p?s-2015. Ao buscarmos estabelecer uma interface entre a produ??o de sons musicais, natureza e sustentabilidade, estamos tamb?m criando um espa?o para a valoriza??o de m?ltiplos discursos e saberes, bem como dos in?meros sujeitos ecol?gicos existentes fora de uma tradi??o naturalista, uma vez que a Ecologia, nos dias atuais, se assume como ideia migrante, encontrando-se em posi??o bastante pr?xima aos movimentos sociais.

▼ Insulin resistance defines the metabolic syndrome and precedes type 2 diabetes, thus is considered as the hallmark for type 2 diabetes. Prolonged hyperglycemia and hyperinsulinemia are both required for the development of classical insulin
resistance. In recent years, accumulative evidence has established that elevated O-GlcNAc levels via either genetic or pharmacological methods lead to insulin resistance in both cultured adipocytes and animal models. Adipocytes, besides being a major
site for energy storage, are endocrine in nature and secrete a variety of proteins (adipocytokines) that can modulate insulin sensitivity, hypertension, food intake, and general energy homeostasis. The link between O-GlcNAc levels, insulin resistance,
and adipocytokine secretion is further explored in this dissertation. First, by using immortalized and primary rodent adipocytes, the secreted proteome of differentiated adipocytes under insulin responsive and two insulin resistant conditions is
explicitly elucidated via shotgun proteomics leading to the identification of 97 and 203 secreted proteins, respectively. More than 80 N-linked glycosylation sites on adipocytokines released by these adipocytes were also mapped. Moreover, we took a step
further to address the quantitative secretome of human primary adipocytes with the same technique. Of the 190 secreted proteins identified, we report 20 up-regulated and 6 down-regulated proteins detected in both insulin resistant conditions. Moreover,
we applied glycomic techniques to examine (1) the N-linked sites from the pool of secreted proteins and (2) the characterization and relative abundance of complex N- and O-glycans released from adipocytes exposed to different conditions. We identified 91
Nglycosylation sites on the secreted proteins derived from 51 proteins, as well as 155 and 29 released N- and O-glycans respectively. There were moderate alterations in the observed N- and O-linked glycans under the different conditions considered. In
short, our studies have provided a list of adipocytokines whose secreted levels vary under insulin resistant conditions. These proteins bear the potential to be prognostic/diagnostic biomarkers for the detection of metabolic syndrome and type 2 diabetes.
Also, comparing the results complied from both classical and non-canonical insulin resistance provides further insights for the role of the O-GlcNAc modification on intracellular proteins in the disease progression of type 2 diabetes.

▼ A impermeabiliza??o dos solos urbanos afeta diretamente o aumento do escoamento superficial e infiltra??o dos solos. O concreto perme?vel usado em pavimentos apresenta-se como uma a??o mitigadora para essas quest?es. A aus?ncia total de finos ou a redu??o da maior parte dele caracteriza a alta permeabilidade e baixa resist?ncia desse concreto. Na pesquisa ? introduzida a metacaulinita no concreto perme?vel para substitui??o parcial do cimento. O estudo foi realizado com ensaios laboratoriais para verifica??o de resist?ncias mec?nicas e determina??o da taxa de infiltra??o da ?gua. As misturas utilizadas neste estudo consistiram em dois tamanhos agregados e dois tipos de agregados gra?dos. Os ensaios foram realizados em amostras de refer?ncia nas quais n?o havia substitui??o do cimento. Como o trabalho foi desenvolvido para placas de concreto de perme?vel a NBR 16416 (ABNT, 2015) determina que a resist?ncia a tra??o na flex?o alcance o m?nimo 2 MPa. Dessa forma foi estabelecido que as amostras de refer?ncia deveriam alcan?ar um m?nimo de resist?ncia de compress?o 8 MPa. Esse resultado foi atingindo ap?s o ajuste das dosagens e o incremento de 5% de areia. Ap?s atingir o objetivo foi realizada a substitui??o de 15% do cimento por metacaulinita. As caracter?sticas mec?nicas de compress?o depois da substitui??o atingiram resist?ncia ? compress?o simples de aproximadamente 10 MPa e de resist?ncia ? tra??o na flex?o ficou com aproximadamente 2,1 MPa. A taxa de infiltra??o da ?gua ficou com valores em torno de 0,14cm/s. O estudo permitiu avaliar que o seixo e a brita 0 n?o apresentaram diferen?as significativas quanto a resist?ncias mec?nicas e permeabilidade. A substitui??o do cimento por metacaulinita aumentou o consumo de ?gua o que provavelmente est? ligado a maior ?rea especifica desse material. A metacaulinita ? um material fino e como umas das caracter?sticas do concreto perme?vel ? a aus?ncia total o quase total do materiais finos a sua aplica??o n?o diminuiu de forma expressiva a permeabilidade do concreto.
The waterproofing of urban soils directly affects the increase of surface runoff and soil infiltration. The permeable concrete used in pavements presents itself as a mitigating action for these issues. The total absence of fines or the reduction of most of them characterizes the high permeability and low strength of this concrete. In research, metakaolinite is introduced in permeable concrete to partially replace cement. The study was carried out with laboratory tests to check mechanical strength and determine the rate of water infiltration. The mixtures used in this study consisted of two aggregate sizes and two types of coarse aggregates. The tests were performed on reference samples in which there was no replacement of cement. As the work was developed for concrete slabs of permeable, NBR 16416 (ABNT, 2015) determines that the flexural tensile strength reaches the minimum 2 MPa. Thus, it was established that the reference samples should reach a minimum compression strength of 8 MPa. This result was…

▼ L'habitation semi-souterraine en tourbe retrouvée
sur le site de Seal Islands (FaAw-5) à l'entrée du détroit de Belle
Isle au Labrador méridional a été fouillée et ensuite analysée dans
les années 1980. Cette étude a permis de proposer qu'elle avait été
occupée, entre 1760-1820, par un groupe inuit ayant subi une
intense acculturation. Les récentes analyses zooarchéologiques
réalisées à partir de l'assemblage faunique du site, dont l'analyse
cémentochronologique et l'étude comparative des marques de
boucherie sur les ossements de phoques, complétées par une analyse
des documents historiques et des données environnementales, ont
permis de proposer que les individus ayant occupé le site de Seal
Islands
n'étaient pas des Inuits, mais plutôt un groupe
d'Européens, du moins en partie. En effet, il est possible que le
site de Seal Islands soit un des premiers sites connus à révéler
des indices d'unions mixtes entre Européens et Inuits, ce qui nous
permettrait de mieux comprendre l'origine des Métis au Labrador.
Par ailleurs, plusieurs traits concernant les stratégies de
subsistance sur ce site ressemblent au mode de vie des Settlers qui
sont arrivés au Labrador en tant qu'employés pour les différents
établissements mercantiles. L'établissement de résidents permanents
européens représente une transition importante par rapport à
l'établissement temporaire et saisonnier de groupes de pêcheurs.
Ceux-ci ont dû s'adapter à un nouveau territoire et un nouveau
calendrier saisonnier afin d'acquérir des produits de subsistance,
de même que des biens avec une valeur commerciale.

▼ La chimie des ions N-acyliminiums est un axe de recherche important dans le domaine de la chimie moderne. L’apport de la catalyse, avec l’utilisation de super acides de Lewis, a permis d’améliorer de nombreux processus synthétiques. Nous avons pu développer des réactions d’α-amidoalkylation catalytiques directes de cétones et d’aldéhydes. Ces réactions sont catalysées par des charges très faibles (0.5-2 mol%) du super acide de Lewis, le triflimidate d’étain IV Sn(NTf2)4 et donnent accès à une large gamme de structures carbonylées très intéressantes, avec de bons rendements. L’influence des différents paramètres gouvernant la réactivité et l’étendue de la méthode ont été étudiées. Par la suite, le potentiel synthétique des produits obtenus a été étudié. Deux stratégies de réactions intramoléculaires ont été testées à partir d’adduits alkylés judicieusement fonctionnalisés, en utilisant soit des catalyseurs à base d’or, soit des catalyseurs de métathèse, permettant d’atteindre quelques structures polycycliques.
AThe chemistry of N-acyliminiums ions is one important area of research in modern organic chemistry. Lewis superacid catalysis has contributed in the improvement of many synthetic processes. We have developed some direct α-amidoalkylation reactions starting from unmodified ketones and aldehydes. The reactions were catalyzed by the Lewis superacid tin IV triflimidate, Sn(NTf2)4, at a very low catalyst loading(0.5-2 mol%), providing access to a set of very interesting carbonylated structures in good yields. The influence of different parameters governing the reactivity and the scope of the reaction were studied. Thereafter, the synthetic potential of the obtained products was evaluated. Two intramolecular approaches from suitably functionalized alkylated products were tested using gold and metathesis catalysts, allowed access to some polycyclic structures.

▼ Les sols agricoles sont la principale source du gaz à effet de serre N₂O. Ces émissions sont caractérisées par une variabilité spatiale et temporelle considérable, ce qui rend très difficile leur quantification. L’UR SOLS étudie depuis 2008 les émissions de N₂O dans une zone agricole du Centre de la France. Spécifiquement, nous avons étudié au laboratoire l’effet de la température sur ces émissions et développé une méthode permettant l’estimation des émissions de N₂O à l’échelle du paysage. De façon surprenante, nous avons observé que les émissions de N₂O n’augmentent pas systématiquement avec la température. L’indicateur Q₁₀ est apparu, pour les émissions de N₂O, variable avec le temps. L’utilisation de l’acétylène, inhibiteur de la réduction de N2O, a révélé que les processus biologiques de production et de consommation de N₂O répondent différemment à la température. Les émissions de N₂O mesurées au champ à l’aide de différentes techniques ont permis d’obtenir des résultats cohérents, avec des moyennes de 43 μg N- N₂O m⁻² h⁻¹ pour la méthode par eddy covariance, 37 μg N- N₂O m⁻² h⁻¹ pour la méthode de fast-box et 71 μg N- N₂O m⁻² h⁻¹ pour la méthode des chambres automatiques sur un blé fertilisé. Des méthodes d’attribution des flux ont été développées pour déterminer de façon exhaustive les variations spatiales et temporelles des émissions de N₂O avec élaboration de cartes originales d’émissions à l’échelle du paysage. L’ensemble de ces résultats pourra être utilisé pour le développement de modèles de fonctionnement des écosystèmes. Ils vont contribuer à quantifier les émissions de N₂O aux échelles adaptées pour les inventaires et les stratégies d’atténuation.
The greenhouse gas N₂O is mainly emitted by soils. Soil emissions are characterized by considerable spatial and temporal variabilities that make their quantification very difficult. While soil N₂O emissions are studied on an agricultural area in the Central France by the UR SOLS since 2008, we specifically studied in the laboratory the effect of temperature on these emissions and also developed a method for upscaling N₂O emissions from the plot to the landscape scales. Surprisingly, N₂O emissions were observed not to increase with temperature. Q₁₀ values, describing N₂O emission sensitivity to temperature, were observed to change over time. The use of acetylene for inhibiting N₂O reduction has revealed that the biological processes involved in the N₂O production and its consumption respond differently to temperature variations. N2O fluxes measured in the field using several methods covering different scales of the landscape gave consistent results. The mean measured N₂O fluxes were 43 μg N- N₂O m⁻² h⁻¹ for the eddy covariance mast, 37 μg N- N₂O m⁻² h⁻¹ for the fast-box over a similar area, while it was 71 μg N- N₂O m⁻² h⁻¹ by the automatic chambers over a fertilized wheat field. Flux attribution methods were developed to determine both the spatial and temporal variability of the N₂O flux over a 1-km landscape, resulting in original maps of N₂O emissions at…

▼ Nous nous sommes attachés à trouver de nouvelles applications de la réaction de transfert O-N acylique pour la synthèse de peptides et de polypeptides. Nous avons mis au point une nouvelle voie pour la synthèse de peptide alcool sur support solide. Cette méthodologie a permis de préparer 3 peptides alcool modèles comme l'Octréotide avec de bons rendements et d'excellentes puretés. Nous avons développé une nouvelle stratégie pour la synthèse de polyamide à partir de polyester via une réaction de multi-transfert O-N acylique. Pour cela, nous avons isolé trois générations de polymères : les polyesters Z-protégés après polymérisation, les polyesters hydrosolubles après le clivage des groupements Z et les polyamides après multi-transfert O-N acylique dans des conditions basiques organiques et à pH physiologique. Cette stratégie a été appliquée à la synthèse de polyamide de sérine et de sérine gamma-homologuée. Maintenant, nous développons une nouvelle stratégie de polymérisation de séquence peptidique contenant une sérine N-protégée en position N-terminale. Comme décrit précédemment pour les polysérines, les objectifs de cette étude sont de synthétiser in fine des polypeptides à partir des polypeptides/esters correspondants.
We founded some news applications of the O-N acyl transfer, notably for the synthesis of peptides and polypeptides. We optimized a new general voice for the preparation of peptides alcohol on solid support. This methodology permits to synthesize 3 peptides alcohol with yield and purity, notably Octreotide. We developed a new strategy for the synthesis of polyamide from polyester using an O-N acyl multi-transfer reaction. We have isolated 3 generations of polymers: the Z-protected polyesters after polymerization (polycondensation and ROP), the unprotected water-soluble polyesters after the cleavage of the protection Z and the polyamides after the O-N acyl multi-transfer in basic organic condition or in phosphate buffer. This methodology was applied to the synthesis of the polyamide serine and gamma-homologated serine. Currently, we are developing a new methodology for the polymerization peptide sequence containing an N-protected serine in N-terminal position. As previously described on polyserine, the objectives of this polymerization are to generate polypeptides from the corresponding polypeptides/esters.
