Abstract (sommario):
Resveratrol butyrate ester (RBE) complexes have demonstrated higher antioxidant capacity and anti-fat accumulation activity in previous studies. In this study, silica gel, high-performance liquid chromatography, and 1H nuclear magnetic resonance were used for separation and identification of RBE complex components. With the exception of resveratrol, five different structures of ester derivatives were separated from silica gel: 3,4′-di-O-butanoylresveratrol (ED2, 18.8%), 3-O-butanoylresveratrol (ED4, 35.7%), 4′-O-butanoylresveratrol (ED5, 4.4%), 3,5,4′-tri-O-butanoylresveratrol (ED6, 1.5%), and 3,5-di-O-butanoylresveratrol (ED7, 0.7%). Among the ester derivatives obtained, ED2 and ED4 were the main ester derivatives in the RBE complex. Thus, the cellular antioxidant activities of the RBE mixture, ED2, and ED4 were evaluated. Results showed that the antioxidant capacity of ED2 and ED4 was higher than that of the RBE mixture, demonstrating that the number and position of butyrate esterification sites are related to cell survival rate and antioxidant capacity. This study is the first to report the successful isolation, structural identification, and cellular biological antioxidant activity of RBE complex derivatives, which are key characteristics for the potential practical application of RBE complexes.

Abstract (sommario):
Introduction: Most of the cytotoxic anticancer drugs belong to substances with both low solubility in aqueous fluids and poor cellular uptake, which lead to lack of specific therapy with apparent side effects. Therefore, there is a need to develop a novel drug delivery that can remotely and selectively release their payload. Curcumin(CUR) is an antibiotic, also a powerful inhibitor of the proliferation of several tumor cells. Aims: The aim of the present work is to highlight and discussed hyaluronic acid (HA ) to be grafted with Mono-6-deoxyl-6-ethylenediamino-γ-cyclodextrin (ɣ-CD-EDA) to shape a hydrogel that ought to structure inclusion complexes with curcumin, bettering its water-solubility and serving as a model drug delivery system Methods: Distinct copolymers had been organized HA grafted with ɣ-cyclodextrin (ɣ-CD-EDA) to form a hydrogel with various HA: ɣ-CD-EDA ratios and characterized, by means of 1H-NMR spectroscopy, zeta potential, Thermogravimetry analysis) TGA) Differential scanning calorimetry (DSC), and transmission electron microscopy (TEM). Furthermore, drug loading Encapsulation efficiency (EE%), and release kinetics, and stability. Also, cytotoxicity and uptake were assessed by flow cytometry, MTT assay and confocal laser microscopy. Wound healing activity was once improved using three cell MDA-MB-231, MCF-7, and fibroblast. Measuring the effect of HA-γ-CD-EDA1-CUR, γ-CD-EDA1-CUR, and CUR free on the Production and Secretion of inflammatory cytokines Result: CUR loading potential used to be at once correlated with extended HA-ɣ-CD-EDA composition and morphological adjustments have been discovered upon CUR binding. The host substances and their CUR inclusion complexes are no longer cytotoxic, and consequently beneficial for CUR and drug delivery. Moreover, HA-γ-CD-EDA1-CUR, γ-CD-EDA1-CUR, and CUR wound healing activity was once improved, and human promonocytic THP-1 cells produce inflammatory mediators such as IL-1β, IL10,IL8, TNF-α,IRAKI and IL6 results showed that the combination HA-γ-CD-EDA1-CUR could be suitable to reduce inflammation and the complex promoted the anti-inflammatory effect by the inhibition of inflammatory mediators. Conclusion: HA grafted with ɣ-cyclodextrin (ɣ-CD-EDA) to form a hydrogel was designed, formulated, and full characterized. Nanoparticles were stable at physiological pH and have released payload. Encapsulation of CUR into polymer increased its selectivity, distribution, and accumulation into the cancer cells. HA-CD-EDA1conjugated curcumin if incorporated in suitable matrix has a potential utility for treatment of wound, and down regulation in THP-1 cells.

Abstract (sommario):
The reversible, weak ground-state aggregate formed by dipole–dipole interactions between an electron donor and an electron acceptor is referred to as an electron-donor–acceptor (EDA) complex. Generally, upon light irradiation, the EDA complex turns into the excited state, causing an electron transfer to give radicals and to initiate subsequent reactions. Besides light as an external energy source, reactions involving the participation of EDA complexes are mild, obviating transition metal catalysts or photosensitizers in the majority of cases and are in line with the theme of green chemistry. This review discusses the synthetic reactions concerned with EDA complexes as well as the mechanisms that have been shown over the past five years.

Abstract (sommario):
ABSTRACT The surface of the mature dengue virus (DENV) particle is covered with 180 envelope (E) proteins arranged as homodimers that lie relatively flat on the virion surface. Each monomer consists of three domains (ED1, ED2, and ED3), of which ED3 contains the critical neutralization determinant(s). In this study, a large panel of DENV-2 recombinant ED3 mutant proteins was used to physically and biologically map the epitopes of five DENV complex-specific monoclonal antibodies (MAbs). All five MAbs recognized a single antigenic site that includes residues K310, I312, P332, L389, and W391. The DENV complex antigenic site was located on an upper lateral surface of ED3 that was distinct but overlapped with a previously described DENV-2 type-specific antigenic site on ED3. The DENV complex-specific MAbs required significantly higher occupancy levels of available ED3 binding sites on the virion, compared to DENV-2 type-specific MAbs, in order to neutralize virus infectivity. Additionally, there was a great deal of variability in the neutralization efficacy of the DENV complex-specific MAbs with representative strains of the four DENVs. Overall, the differences in physical binding and potency of neutralization observed between DENV complex- and type-specific MAbs in this study demonstrate the critical role of the DENV type-specific antibodies in the neutralization of virus infectivity.

Abstract (sommario):
The pharmacokinetic profile and tissue uptake of daidzein (DAI) was determined in rat serum and tissues (lungs, eyes, brain, heart, spleen, fat, liver, kidney, and testes) after intravenous and intraperitoneal administration of DAI in suspension or complexed with ethylenediamine-modified γ-cyclodextrin (GCD-EDA/DAI). The absolute and relative bioavailability of DAI suspended (20 mg/kg i.v. vs. 50 mg/kg i.p.) and complexed (0.54 mg/kg i.v. vs. 1.35 mg/kg i.p.) was determined. After i.p. administration, absorption of DAI complexed with GCD-EDA was more rapid (tmax = 15 min) than that of DAI in suspension (tmax = 45 min) with a ca. 3.6 times higher maximum concentration (Cmax = 615 vs. 173 ng/mL). The i.v. half-life of DAI was longer in GCD-EDA/DAI complex compared with DAI in suspension (t0.5 = 380 min vs. 230 min). The volume of distribution of DAI given i.v. in GCD-EDA/DAI complex was ca. 6 times larger than DAI in suspension (38.6 L/kg vs. 6.2 L/kg). Our data support the concept that the pharmacokinetics of DAI suspended in high doses are nonlinear. Increasing the intravenous dose 34 times resulted in a 5-fold increase in AUC. In turn, increasing the intraperitoneal dose 37 times resulted in a ca. 2-fold increase in AUC. The results of this study suggested that GCD-EDA complex may improve DAI bioavailability after i.p. administration. The absolute bioavailability of DAI in GCD-EDA inclusion complex was ca. 3 times greater (F = 82.4% vs. 28.2%), and the relative bioavailability was ca. 21 times higher than that of DAI in suspension, indicating the need to study DAI bioavailability after administration by routes other than intraperitoneal, e.g., orally, subcutaneously, or intramuscularly. The concentration of DAI released from GCD-EDA/DAI inclusion complex to all the rat tissues studied was higher than after administration of DAI in suspension. The concentration of DAI in brain and lungs was found to be almost 90 and 45 times higher, respectively, when administered in complex compared to the suspended DAI. Given the nonlinear relationship between DAI bioavailability and the dose released from the GCD-EDA complex, complexation of DAI may thus offer an effective approach to improve DAI delivery for treatment purposes, for example in mucopolysaccharidosis (MPS), allowing the reduction of ingested DAI doses.

Abstract (sommario):
In this study, both practical and theoretical aspects of the solubility of edaravone (EDA) in Deep Eutectic Solvents (DESs) were considered. The solubility of edaravone in some media, including water, can be limited, which creates the need for new efficient and environmentally safe solvents. The solubility of EDA was measured spectrophotometrically and the complex intermolecular interactions within the systems were studied with the COSMO-RS framework. Of the four studied DES systems, three outperformed the most efficient classical organic solvent, namely dichloromethane, with the DES comprising choline chloride and triethylene glycol, acting as hydrogen bond donor (HBD), in a 1:2 molar proportion yielding the highest solubility of EDA. Interestingly, the addition of a specific amount of water further increased EDA solubility. Theoretical analysis revealed that in pure water or solutions with high water content, EDA stacking is responsible for self-aggregation and lower solubility. On the other hand, the presence of HBDs leads to the formation of intermolecular clusters with EDA, reducing self-aggregation. However, in the presence of a stoichiometric amount of water, a three-molecular EDA–HBD–water complex is formed, which explains why water can also act as a co-solvent. The high probability of formation of this type of complexes is related to the high affinity of the components, which exceeds all other possible complexes.

The cyclopropanation of various alkenes with different diazoester compounds was investigated using two different μ-oxo-bis[(salen)iron(III)] complexes, [Fe(3,3',5,5'-tBu4salen)]2O and [Fe(salen)]2O. Ethyl diazoacetate (EDA), tert-butyl diazoacetate (tBDA), and ethyl diazoacetoacetate (EDAA) were used with mono- and disubstituted terminal olefins (styrene and 1,1-diphenyl ethylene, respectively), internal olefin (trans-β-methyl styrene), and an electron-rich alkene (n-butyl vinyl ether). Moderate-to-good cyclopropanation yields were obtained for most substrates.

Abstract (sommario):
The interaction of several aliphatic amines as n-donors and dinitrobenzenes (DNB) as π-acceptors has been studied in n-hexane. The formation of electron donor – acceptor (EDA) complexes is proposed to explain the spectroscopic behaviour of the mixtures. The stability constants (Ks) for these complexes have been calculated by an iterative procedure. For a given acceptor, the donor strength of RNH2 > R2NH > R3N was found. This order is explained by considering the role that steric effect may play in the EDA complex formation. On the other hand, the fact that for a given donor Ks follows the order 1,2-DNB > 1,3-DNB > 1,4-DNB, and that 1,2-DNB reacts with primary amines, led to the proposal of orientational complexes. These EDA complexes may be considered intermediates in aromatic nucleophilic substitution reactions.

Abstract (sommario):
Les recherches présentées dans ce manuscrit de thèse se divisent en deux parties. Dans la première partie, nous avons étudié la dégradation photocatalysée du N-méthoxy-N-(triméthylsilylméthyl)benzaldéhyde en présence de rose bengale dans l’acétonitrile. Les expériences de RMN 1D, la RMN 1H photo-CIDNP, ainsi que les analyses 2D 1H-13C HSQC et HMBC, combinées à une illumination in situ et ex situ, ont permis d'élucider la structure de plusieurs intermédiaires et produits formés durant cette réaction. L'illumination ex situ, réalisée à l'aide d'un système de flux continu, a été particulièrement utile pour compléter les résultats obtenus in situ et pour établir des comparaisons avec ceux obtenus par synthèse, soulignant ainsi l'importance de l'illumination ex situ dans l'étude des réactions en photochimie. Par ailleurs, les expériences de RMN 1H photo-CIDNP ont clairement démontré que la dégradation de l'éther de l’hémiaminal en présence de rose bengale passe par la formation d'un radical cation, sans engendrer de formation de 1,3-dipôle.Dans la seconde partie, nous nous sommes intéressés à la mécanistique de la réaction d’alkylation photo-induite via un complexe EDA (sel de Katritzky/DIPEA), en utilisant la RMN couplée à l’illumination in situ. Grâce aux expériences de RMN 1H photo-CIDNP, nous avons mis en évidence la présence de deux complexes EDA distincts dans le milieu réactionnel : un complexe 1:1 et un complexe 1:2 (sel de Katritzky : DIPEA), absorbant respectivement à λ = 450 nm et à λ = 520 nm. Les études de RMN 1D 1H et 1H photo-CIDNP ont révélé l'absence de diffusion du groupe partant du sel de Katritzky, prouvant ainsi que la réaction d’alkylation s'effectue dans la sphère de solvatation du complexe EDA. Ces observations, combinées aux données extraites des expériences de RMN 1H DOSY, ont permis d'identifier la nature des agrégats (complexe EDA/substrat) impliqués dans la réactivité aux deux longueurs d'onde, démontrant clairement le lien étroit entre la proportion de ces agrégats dans le milieu réactionnel et le rendement de la réaction d’alkylation photo-induite
The research presented in this thesis manuscript is organized into two main sections. The first section investigates the photocatalytic degradation of N-methoxy-N-(trimethylsilylmethyl)benzaldehyde in the presence of rose Bengal in acetonitrile. We utilized various techniques, including 1D NMR experiments, 1H photo-CIDNP, and 2D 1H-13C HSQC and HMBC analyses, alongside both in situ and ex situ illumination. These methods enabled us to elucidate the structures of several intermediates and products formed during the reaction. Notably, ex situ illumination, executed through a continuous flow system, proved particularly beneficial for complementing our in situ results and making comparisons with synthesized products, underscoring the significant role of ex situ illumination in the study of photochemical reactions. Moreover, the 1H photo-CIDNP experiments clearly indicated that the degradation of the hemiaminal ether in the presence of rose Bengal occurs via the formation of a cation radical, without the generation of any 1,3-dipole intermediates.In the second section, we shifted our focus to the mechanism of the photo-induced alkylation reaction via an EDA complex (Katritzky salt/DIPEA), employing NMR in conjunction with in situ illumination. 1H photo-CIDNP experiments revealed the presence of two distinct EDA complexes in the reaction medium: a 1:1 complex and a 1:2 complex (Katritzky salt: DIPEA), which absorb at λ = 450 nm and λ = 520 nm, respectively. Additional 1D 1H NMR and 1H photo-CIDNP studies demonstrated the absence of leaving group diffusion from the Katritzky salt, confirming that the alkylation reaction occurs within the solvation sphere of the EDA complex. These findings, along with data obtained from 1H DOSY NMR experiments, allowed us to ascertain the nature of the aggregates (EDA complex/substrate) participating in reactivity at both wavelengths. This clearly illustrates the close relationship between the proportion of these aggregates in the reaction medium and the yield of the photo-induced alkylation reaction

Cette thèse est dédiée à l’étude du phénomène d’explosion en temps fini pour les équations semi-linéaires des ondes. On traite deux modèles dans ce travail.Dans une première direction, on considère l’équation semi-linéaire des ondes à valeurs complexes avec une nonlinéarité en puissance. On caractérise d’abord toutes les solutions du problème stationnaire comme une famille à deux paramètres.Ensuite, on utilise une approche de système dynamique pour montrer que la solution en transformation auto-similaire s’approche d’une solution stationnaire particulière dans l’espace d’énergie, dans le cas des points non caractéristiques.Ceci donne le profil à l’explosion pour l’équation originale dans le cas non-caractéristique.Dans une seconde direction, on étudie l’exemple de l’équation des ondes avec source exponentielle critique en dimension 1. On généralise les résultats de Godin pour une classe de données initiales beaucoup plus grandes. On prouve des estimations à l’explosion pour tout point de l’espace et on donne une estimation optimale du taux d’explosion pour les points non-caractéristiques
This thesis is devoted to the study of the finite time blow-up phenomena for the semilinear waves equations. We treat two models in this work.In the first part, we consider a complex-valued solution for the semilinear wave equation with power nonlinearity. We first characterize all the solutions of the associated stationary problem as a two-parameter family. Then, weuse a dynamical system formulation to show that the solution in self-similar variables approaches some particular stationary one in the energy norm, in the non-characteristic case. This gives the blow-up profile for the original equation in the non-characteristic case.The second part is dedicated to the study of the semilinear wave equation with exponential nonlinearity in one space dimension. We generalize the results of Godin to a much larger class of initial data. We prove blow-up estimates near any point and give an optimal bound on the blow-up rate near the non characteristic points

Abstract (sommario):

This thesis is a summary of five papers with focus on adsorption processes of various monocarboxylates and aminocarboxylates at the water/goethite interface. Interaction of organic acids at the water/mineral interfaces are of importance in biogeochemical processes, since such processes have potential to alter mobility and bioavailability of the acids and metal ions.

In order to determine the coordination chemistry of acetate, benzoate, cyclohexanecarboxylate, sarcosine, MIDA (methyliminediacetic acid), EDDA (ethylenediamine-N,N’-diacetic acid) and EDTA (ethylenediamine-N,N’-tetraacetic acid) upon adsorption to the goethite (alpha-FeOOH) surface, a combination of quantitative measurements with attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) was utilized.

Over the pH range studied here (pH 3- 9) all ligands, except for sarcosine, have been found to form surface complexes with goethite. In general, theses were characterized as outer sphere surface complexes i.e. with no direct interaction with surface Fe(III) metal ions. Furthermore, two types of different outer-sphere complexes were identified, the solvent-surface hydration-separated ion pair, and hydration-shared ion pair. For the monocarboxylate surface complexes distinction between these two could be made. At high pH values the solvent-surface hydration-separated ion pair was the predominating complex, while at low pH the surface complex is stabilized through the formation of strong hydrogen bonds with the goethite surface. However, it was not possible to clearly separate between the two outer-sphere complexes for coordination of the aminocarboxylates with the surface of goethite. Additionally, EDDA also formed an inner-sphere surface complex at high pH values. The EDDA molecule was suggested to coordinate to the surface by forming a five membered ring with an iron at the goethite surface, through the amine and carboxylate groups.

Contrary to the other ligands studied, EDTA significantly induced dissolution of goethite. Some of the dissolved iron, in the form of the highly stable FeEDTA- solution complex, was indicated to re-adsorb to the mineral surface as a ternary complex. Similar ternary surface complexes were also found in the Ga(III)EDTA/goethite system, and quantitative and spectroscopic studies on adsorption of Ga(III) in presence and absence of EDTA showed that EDTA considerably effects speciation of gallium at goethite surface.

The collective results in this thesis show that the affinity of these ligands for the surface of goethite is primarily governed by their chemical composition and structure, and especially important are the types, numbers and relative position of functional groups within the molecular structure.

Abstract (sommario):
In this thesis, I analyze how conflict and affection, as designed by the German philosopher Axel Honneth, especially in his work The Struggle for Recognition: Moral Grammar of Social Conflicts, interfere with the dynamics of a group made up of professors and pre-service teachers in e-learning. From the perspective of Complex Thought of the French sociologist Edgar Morin, I conceive the group as a complex social system. As an exploratory research, I started with the reading of the autobiographical essays wrote by the students who completed the Degree in Spanish in Federal University of Santa Maria in 2013. In those essays, I identified situations around conflicts and affective recognition experienced by the pre-service teachers, and then I selected some informants. These informants participated in narrative interviews, in which they told their respective academic trajectories. Later, I also interviewed the professors, mentioned by them in situations of affective or conflictual interaction. I analyzed all this material from the perspective of Reconstructive Hermeneutics, making the different narratives dialogue to reconstruct the situations experienced by the narrators. From this reconstruction emerges the fact that affectivity is a constant in the relations established in e-learning and we can see it as a facilitator of learning, as well as a cohesive force that tends to keep straight the complex social system. Also, emerge conflict situations. Although the conflict is not seen as something desirable, it shows potential as a maintainer of the complex social system, and it demonstrates power to stimulate new ways of thinking, to create innovative strategies of work and new dynamics of interaction between people. Innovation resulting from the conflict serves as negentropic force, which is opposed to entropy or systemic loss of energy, contributing to the longevity of this system and to obtain positive results in educational terms. I hope these findings tend to contribute to the understanding of the dynamics of relationships in e-learning, allowing its professors understand the importance of human interactions that are revealed behind the computers.
Neste trabalho, analiso de que forma o conflito e a afetividade, conforme concebidos pelo filósofo alemão Axel Honneth, sobretudo em sua obra Luta por Reconhecimento: a gramática moral dos conflitos sociais, interferem na dinâmica de um grupo constituído por professores e professores em formação na modalidade Educação a Distância. Concebo o grupo como um sistema social complexo a partir da perspectiva do Pensamento Complexo do sociólogo francês Edgar Morin. Como fonte de dados, debruço-me, inicialmente, sobre os trabalhos de conclusão de curso, inseridos no gênero memorial de formação, dos alunos que concluíram o Curso de Licenciatura em Espanhol e Literaturas EaD da Universidade Federal de Santa Maria em 2013. A partir de uma pesquisa exploratória, em que foram identificados memoriais narrando situações de conflito e de reconhecimento afetivo vividas pelos professores em formação, selecionei alguns informantes. Esses informantes participaram, então, de entrevistas narrativas, em que contaram suas respectivas trajetórias acadêmicas. Mais tarde, os professores por eles mencionados em situações de interação afetiva ou conflitiva foram também entrevistados. Todo esse material foi analisado a partir da perspectiva da Hermenêutica Reconstrutiva, fazendo dialogar as diferentes narrativas a fim de reconstituir as situações vividas pelos narradores. Dessa reconstrução emerge o fato de que a afetividade é uma constante nas relações estabelecidas em EaD e se mostra como elemento facilitador da aprendizagem, além de uma força de coesão que tende a manter o sistema complexo social em boa marcha. Emergem, também, as situações de conflito. Apesar de o conflito não ser encarado como algo desejável, demonstro seu papel como potencial mantenedor do sistema social complexo, pois tem o poder de estimular novas maneiras de pensar, a criação de estratégias inovadoras de trabalho e de novas dinâmicas de interação entre as pessoas. A inovação decorrente do conflito funciona como força neguentrópica, que se contrapõe à entropia ou perda de energia sistêmica, contribuindo para a longevidade desse sistema e para a obtenção de resultados positivos em termos pedagógicos. Essas conclusões tendem a contribuir com a compreensão sobre as dinâmicas das relações na Educação a Distância, permitindo aos seus professores uma percepção maior sobre a importância das interações humanas que se descortinam por detrás dos computadores.

Abstract: The Cerrado biome has undergone modifications in recent decades, losing part of its original cover to annual crops, pastures and planted forests, having different land uses. In this work, the interactions between the different land uses in areas of the Cerrado biome, as well as the soil carbon dynamics and the latent factors formed by the physical and chemical attributes of the soil through structural equation analysis models were studied. with the aid of multivariate statistical techniques. Experimental tests were performed at the Teaching, Research and Extension Farm (FEPE / UNESP), located in Selvíria-MS: Eucalyptus planted forest Eucalyptus camaldulensis (EU); Planted Pine Forest - Pinus caribaea var. hondurensis (PI); Silvipastoral system (SI) with an area containing Aroeira (Myracrodruon urundeuva) and native grass (Brachiaria decumbens), and Mata Nativa (MN). The effects of physical attributes: soil density (Ds), macroporosity (Ma), microporosity (Mi) and chemicals attributes were studied with special emphasis on properties related to soil carbon dynamics: soil organic matter (MO), soil carbon stock (EstC), soil nitrogen stock (EstN), carbon and nitrogen ratio (C / N), and the degree of soil organic matter (HLIFS). Soil CO2 emission (FCO2), soil moisture and temperature were evaluated in the areas during three distinct periods (defined from the water regime observed in the areas) called P1, P2 and P3, season rainfall, drought and transition, respectively, between March...

Testo completo
Abstract (sommario):
Adenovirus E1A (AdE1A) is a viral oncoprotein that targets many cellular proteins and pathways, mainly those involved in transcriptional regulation. Proteasomes represent the major non-lysosomal mechanism responsible for protein degradation. Following interferon-γ treatment, three proteasome subunits are replaced by immunosubunits LMP2, LMP7 and MECL-1 producing immunoproteasomes. The proteasome and immunoproteasome generate peptide antigens for MHC class I presentation to cytotoxic T-cells. In this study, the effect of AdE1A on human immunoproteasomes as well as MHC class I and class II cell surface expression was examined. It was found that AdE1A interacts with the immunoproteasome subunit MECL-1 through its N-terminal and CR3 regions. AdE1A also down-regulated all three immunosubunit expressions during adenovirus infection, transformation and AdE1A transfection, with the exception of Ad5-transformed cells where immunosubunit expression remained unchanged. Furthermore, MHC class I expression remained unaffected in the same three backgrounds. However, in the Ad12 transformants MHC class I was generally reduced prior to IFNγ treatment but was expressed after. MHC class II surface expression, in contrast, was down-regulated in all cases, except in Ad5 infected cells. Similarly, AdE1A reduced IFNγ-stimulated STAT1 phosphorylation and transcriptional response to IFNγ. And finally, T-cell recognition of target cells was reduced in the presence of AdE1A. In conclusion, AdE1A targets the human immunoproteasome, both through direct binding and down-regulation of expression. It also targets the expression of MHC class I and class II surface expression.

Abstract (sommario):
Cette thèse est consacrée à l'étude de solutions globales et régulières de certaines EDP hamiltoniennes, du point de vue de la croissance de leurs normes de Sobolev. Un tel phénomène traduit une modification de la répartition de l'énergie dans l'espace des fréquences, appelée parfois "turbulence faible". On étudie d'abord une équation d'évolution non-linéaire où intervient un laplacien fractionnaire, et l'on prouve des estimées a priori sur la vitesse de croissance des normes de Sobolev. On introduit ensuite une équation où de telles estimées sont optimales : une équation de Szegő, intégrable, avec une non-linéarité quadratique, et où certaines solutions régulières croissent à vitesse exponentielle tout en restant bornées dans l'espace d'énergie. On classifie les ondes progressives de cette équation de Szegő quadratique, et l'on met en évidence l'instabilité d'une partie d'entre elles. Enfin, on exhibe pour cette équation une hiérarchie de lois de conservation, qui permet d'étudier plus précisément les solutions rationnelles turbulentes
In this thesis we study global smooth solutions of certain Hamiltonian PDEs, in order to capture the possible growth of their Sobolev norms. Such a phenomenon is typical for what is sometimes called "weak turbulence" : a change in the distribution of energy between Fourier modes. We first study a nonlinear evolution equation involving a fractional Laplacian, and we prove a priori estimates on the growth of Sobolev norms. We then introduce an equation where these estimates turn out to be optimal : an integrable Szegő equation with a quadratic nonlinearity, which admits exponentially growing smooth solutions that remain bounded in the energy space. We classify the traveling wave solutions of this quadratic Szegő equation, and show that some of them are unstable. Eventually we find a hierarchy of conservation laws for this equation, which leads us into a deeper study of rational turbulent solutions

Abstract (sommario):
Protocol to Manage Relationships Today explains the contemporary value of protocol, not only for monarchies or diplomatic institutes, but for any non-profit or for-profit organisation. This book presents modern protocol as a tool to build strong, authentic networks of reciprocal relationships. When used effectively protocol can: - Increase the effect of the networking activities of an organisation. Protocol gives a professional structure to relationship management, to achieve access to the 'right' networks and a reciprocal relationship with the most valued stakeholders. - Deepen relationships. In our world there is so much focus on pragmatism in building relationships - protocol focuses on the common ground to gain value. - Be used as a valuable tool in a post COVID-19 era, where the need for space and time to build real and authentic relationships is well understood. The book defines how tested values perfectly fit in today's society, where modern organisations want to build effective relationships and communities. This book is focused on developing an increasingly vital expertise for professionals who deal with complex relationship management issues on a strategic and tactical operational level. They come from different fields, such as government institutions, non-profit organisations and commercial environments. This book also gives protocol officers a contemporary approach towards the application of protocol. It is not designed as a complete guide to all the rules of protocol, but it describes how to translate the context into a tailor-made protocol for each meeting or event. The book explains protocol as a flexible method to handle unique situations. Protocol is presented on four levels: the 'why' of protocol; the strategic and tactical level; the practical implementation; and the execution of protocol. Protocol to Manage Relationships Today is written by Europe's foremost protocol experts with collective years of experience with the management of networking meetings and events at the highest level.

Abstract (sommario):
The first complete reference on the military-industrial complex, from its Cold War era expansion to the present. The Military-Industrial Complex and American Society addresses the broad subject of the political economy of defense research and its wide-reaching effects on many aspects of American life. Ranging from the massive arms buildup of the Cold War to the influx of private contractors and corporations such as Halliburton, it reveals the interconnectedness of the military, industry, and government within the history of this public/private enterprise. The Military-Industrial Complex and American Society offers over 100 alphabetically organized entries on a wide of range of significant research bodies and government agencies, as well as important people, events, and technologies. In addition, a series of essays looks at such essential topics as propaganda, think tanks, defense budgeting, the defense industry and the economy, and the breakdown of the military-industrial complex in Vietnam. With this work, students, policymakers, and other interested readers will understand the ramifications of the relationships between industry, scientific and technological communities, the government, and society.

Abstract (sommario):
La Unión Europea está llevando a cabo una decidida apuesta estratégica para liderar una sociedad digital basada en la apertura de los datos con pleno respeto a los derechos y libertades fundamentales. Para ello ha impulsado una reforma del marco normativo aplicable a los datos abiertos y la reutilización de la información en manos del sector público que ha tenido lugar a través de la Directiva (UE) 2019/1024 del Parlamento Europeo y del Consejo, de 20 de junio de 2019, regulación complementada en España mediante el Real Decreto-Ley 24/2021, de 4 de noviembre. La innovación tecnológica que estamos viviendo en los últimos años ha motivado la necesidad de actualizar el marco normativo en este ámbito. En concreto, la reforma se ha planteado con la finalidad de impulsar decididamente la disponibilidad de la información en manos del sector público y potenciar la utilización de tecnologías destinadas al tratamiento de los datos, en particular para la aplicación de soluciones basadas en la automatización y la Inteligencia Artificial. En este libro se realiza un análisis completo y exhaustivo de las principales novedades que incorporan dichas normas, convirtiéndose en la primera obra publicada en España donde se estudia monográficamente esta regulación. Con este trabajo se ha pretendido, además, ofrecer criterios interpretativos que faciliten su aplicación práctica en el proceso de apertura de la información por parte de las Administraciones y entidades del sector público. Asimismo, se formulan propuestas de regulación para la futura evolución del marco normativo en este ámbito que, sin duda, van a ser de utilidad inmediata teniendo en cuenta las reformas anunciadas por la Comisión Europea en el marco de la Estrategia Europea de Datos.

Abstract (sommario):
En el ámbito universitario el profesorado y los estudiantes crean obras, fonogramas, audiovisuales, bases de datos y otras prestaciones por las que les corresponden derechos de propiedad intelectual. En el proceso de obtención de estas obras y prestaciones o en sus actividades académicas utilizan creaciones y trabajos ajenos. En relación con ello muchas veces desconocen hasta qué punto quedan protegidos como titulares de derechos de propiedad intelectual. También resulta difícil para ellos averiguar en qué casos el uso de materiales ajenos es libre o hace falta solicitar el consentimiento de sus titulares. Esta guía pretende facilitar la comprensión de tales cuestiones al profesorado y al alumnado universitarios, aunque también puede resultar útil en educación secundaria o bachillerato. En la primera parte explica en qué consiste el derecho de propiedad intelectual, la diferente naturaleza y duración de las facultades que lo integran o las distintas categorías de objetos protegidos. También analiza los procesos de creación en que participan varias personas y a quién corresponde el ejercicio de los derechos en cada caso. En el resto de capítulos trata de la utilización de las obras y prestaciones ajenas: Examina las obras y prestaciones que están en el dominio, y describe los usos que no requieren de autorización por encajar en límites como el de cita o ilustración de la enseñanza. En esta parte se tienen en cuenta los hábitos del profesorado y del alumnado universitarios y se clasifican los distintos modos de proceder aclarando cuándo se trata de usos que se pueden realizar con seguridad porque se ajustan a la Ley, cuándo resulta dudosa su legalidad por no estar previstos o por otras circunstancias, y cuándo los usos están claramente prohibidos. La guía se completa con una reseña bibliográfica, direcciones de internet y con un extracto de los preceptos del Texto Refundido de la Ley de propiedad intelectual.

Abstract (sommario):
Most research about simulator adaptation focus on driving style and participants' comfort. However, in recent years, there is a growing interest in physiological data analysis as part of the user experience (UX) assessment. Furthermore, the application of machine learning (ML) techniques to those data may allow the automatic detection of stress and cognitive load. Previously, we noticed that new participants in experiments with our simulator were often in a constant state of tension. This prevented optimal training of our ML models as many of the collected data were not representative of a person's normal state.Our work focuses on improving driver's UX by keeping the cognitive load and stress at levels that do not interfere with the primary task of driving. We use a custom-made driving simulator as our testing platform and evaluate participants' emotional state with physiological signals, specifically electrodermal activity (EDA). EDA is the variation of the skin conductance created by sweat glands. It is linked to the sympathetic nervous system and is an indication of physiological and psychological arousal. We selected EDA because several studies have shown that it is a fast indicator of stress and cognitive load.To ensure that we are consistently collecting accurate data that could be fed to ML algorithms, we need to be able to correlate physiological reactions to external stimuli. We want to avoid them to be confused with general tension. Therefore, we need to determine the time it takes for most participants to physiologically adapt to our simulator. In this between-subjects study, we examined the impact of short time (ca. 10 min) exposures to the simulation and compared it with a longer exposure period (ca. 35 min).Another problem we faced was that some participants were too indisposed by driving in the simulator to complete testing sessions. Therefore, we needed to find a way to discriminate them during the recruitment process. Literature has shown that there might be a link between motion sickness and simulator sickness and in this study, we searched for a correlation between the motion sickness susceptibility questionnaire (MSSQ) and the self-reported simulator sickness using the simulator sickness questionnaire (SSQ).For our investigation, we recruited 22 people through an agency. They were divided in two groups. Group A (short-time exposures) had 10 participants between 25 and 69 years old (M=49.5; SD=17.1, 5 women, 5 men) and group B (long-time exposure) had 12 people between 28 and 65 years old (M=43; SD=12.8, 5 women, 7 men). We requested from the agency to recruit only active drivers of automatic transmissions cars as our simulator mimics this type of vehicle.Motion sickness susceptibility and discomfort felt in the simulator are moderately correlated. The coefficient value is 0.51. The number of participants of our study being small, further research is necessary to determine if the MSSQ can be used as a discriminator in the recruitment phase. In addition, we can conclude that a longer exposure of 35 min results overall in better physiological adaptation.

Abstract In this study, dense yttria coatings are produced by conventional flame spraying using a yttrium ethylene diamine tetra acetic acid (Y-EDTA) complex as the feedstock powder. By adjusting spray parameters, the organic components in the EDTA are completely decomposed and only crystalline Y2O3 phases are found in the deposits. Compared to atmospheric plasma sprayed Y2O3, Y-EDTA coatings produced by reactive flame spraying have better surface morphologies with fewer microcracks and are obtained at lower cost.

Abstract (sommario):
Rhizoferrin, a siderophore produced by Rhizopus arrhizus, has been shown in previous studies to be an outstanding Fe carrier to plants. However, calculations based on stability constants and thermodynamic equilibrium lead to contradicting conclusions. In this study a kinetic approach was employed to elucidate this apparent contradiction and to determine the behavior of rhizoferrin under conditions representing soil and nutrient solutions. Stability of Fe3+ complexes in nutrient solution, rate of metal exchange with Ca, and rate of Fe extraction by the free ligand were monitored for rhizoferrin and other chelating agents by 55Fe labeling. Ferric complexes of rhizoferrin, desferri-ferrioxamine-B (DFOB), and ethylenediamine-di(o-hydroxyphenylacetic acid) (EDDHA) were found to be stable in nutrient solution at pH 7.5 for 31 days, while ferric complexes of ethylenediaminetetraacetic acid (EDTA) and mugineic acid (MA) lost 50% of the chelated Fe within 2 days. Fe-Ca exchange in Ca solutions at pH 8.7 revealed rhizoferrin to hold Fe at non-equilibrium state for 3-4 weeks at 3.3 mM Ca and for longer periods at lower Ca concentrations. EDTA lost the ferric ion at a faster rate under the same conditions. Fe extraction from freshly prepared Fe-hydroxide at pH 8.7 and with 3.2 mM Ca was slow and followed the order. DFOB > EDDHA > MA > rhizoferrin > EDTA. Based on these results we suggest that a kinetic rather than equilibrium approach should be the basis for predictions of Fe-chelates efficiency. We conclude that the non-equilibrium state of rhizoferrin is of crucial importance for its behavior as a Fe carrier to plants.

Abstract (sommario):
This is a new revision of the Year 2 work. The NDE-3-2 project seeks to advance the state of the art for integrity assessment of difficult to inspect pipelines by proposing guidance for application of alternate inspection approaches other than hydrostatic test, in-line inspection and ECDA/ICDA currently prescribed by Code and Regulations. The hydrostatic test and in-line inspection methods for integrity assessment have in common the concept that the full length of the pipeline is assessed. Many pipelines exhibit configuration and operational issues that preclude integrity assessment by the prescribed methods. The ECDA/ICDA structured processes employ evaluation of protective barriers followed by deployment of a small sample of high resolution wall thickness measurements. The NDE-3-2 study proposes a new structured process that evaluates low resolution NDE data of the pipe wall for the full length of the pipeline followed by statistically significant numbers of high resolution wall thickness measurements to predict the condition of the pipeline relative to the fitness for service criterion of corroded pipe such as prescribed in ASME B31G. While conventional ILI inspections or hydrotest rely on full coverage as the basis for evaluating the integrity of a pipeline segment, this structured process would seek to use partial inspections at discrete locations and then use Extreme Value Analysis to estimate the integrity of pipeline segments. The objective is not to provide guidance to replace ILI or hydrostatic testing but rather to offer an alternative for the purposes of gathering data to justify the safe prioritization of piggability conversion or pipeline replacement of difficult to inspect pipelines for both onshore and subsea. This report documents the current state-of-the-art for corrosion location NDE, selection models, and Extreme Value Analysis (EVA) Methodologies for deployment in a structured process as an Alternative to In-Line Inspection of difficult to inspect pipelines. The research on NDE screening technologies addressed in this report reviews technologies identified in the Year 1 work that can be used to screen the condition of pipe wall along its full length as well as existing location selection models such as employed by Direct Assessment Methodologies. This report leverages extensive research that has been conducted on existing Extreme Value Analysis Methodologies from multiple sources and applications including metal corrosion (HOIS, HSE), pipeline corrosion, metocean criteria, wind loading, and multiple textbooks. Multiple case studies are summarized in this report that demonstrate the use of the Partial Inspection Integrity Assessment process utilizing EVA on segments of a pipeline compared to results from full length integrity assessments (either ILI or hydrotest). This report also documents a full Extreme Value Analysis using a demonstration case study and then compares the EVA results with the wall thickness measurements from a full length integrity assessment as a validation example. Ultimately, it is the goal of NDE-3-2 to identify more case studies that might serve as demonstrations. The report also identifies gaps that currently exist and the work that must be completed to develop a complete validated structured process required to deploy the technologies for integrity assessment of difficult to inspect pipelines. The research also aims to compare predictions of remaining life using statistical approaches applied to the partial inspection data with remaining life obtained from conventional integrity assessment using ILI or hydrostatic test.

Testo completo
Abstract (sommario):
The time-dependent seismic risk of bridges is assessed while account accounting for the effect of aftershocks and the uncertainty in the damage state after a mainshock event. To achieve this, a Markov risk-assessment framework is adopted to account for the probabilistic transition of the bridge structure through different damage states and time-dependent aftershock hazard. The methodology is applied to three typical California bridge configurations that differ only based on their era of design and construction. Era 11, Era 22, and Era 33 designations are used for the three bridges, which are designed and detailed to reflect pre-1971, 1971–1990 and post-1990 construction. In addition to mainshock-only evaluations (used as a benchmark to quantify the additional risk posed by aftershocks), pre-mainshock (to account for the uncertainty in the occurrence of mainshock and aftershock events) and post-mainshock (which are based on a conditioning mainshock event and bridge damage state) seismic risk assessments are performed. To support these assessments, a set of 34 pairs of ground motions from as-recorded mainshock–aftershock sequences is assembled. Sequential nonlinear response history analyses (including incremental dynamic analyses) are used to obtain the response demands when the structural models of all bridges are subjected to mainshock-only records or mainshock–aftershock record-pairs. Physical damage in both the mainshock and mainshock–aftershock environments is defined using the following mutually exclusive and collectively exhaustive limit states: Intact, Slight, Moderate, Extensive, and Complete. For both the pre- and post-mainshock assessments, the additional risk caused by aftershock hazard is found to be higher for the older bridges (i.e., Era 11 and Era 22) and more severe conditioning damage states. A direct correlation between the bridge’s age and the increase in seismic risk due to aftershock hazard was also observed for the pre-mainshock assessment. It is suggested that the proposed methodology be used to make informed decisions regarding the appropriateness and timing of bridge closures (partial and complete) following a seismic event while considering aftershock hazard.

Abstract (sommario):
This report critically examines the nature of the distinction between traditional inter-state diplomacy and sustainable development diplomacy. It then sets out the institutional changes which are necessary for the achievement of sustainable development diplomacy. Multi-stakeholder partnerships have been identified as a key means of implementation for the Sustainable Development Goals (SDGs). Given the increasing centrality of the United States (US)–China relationship in global development cooperation, understanding the modalities of their engagement may provide useful insights into how partnerships may be cultivated and deepened to realise the SDGs. The Covid-19 pandemic and climate change have demonstrated the interconnection of the world, as well as the interconnection of challenges of the world. Sustainable development diplomacy is needed now more than ever to prioritise development strategies of different states and work on common shared challenges. Sustainable development diplomacy can only work when different actors recognise the value of the common goals and are willing to make an effort to accomplish them. Global sustainable development diplomacy requires a stronger policy agenda and greater cohesion. This report explores the idea of sustainable development diplomacy and, through two sectoral case studies, explores the nature, function, and rationale for interactive engagement. The form and structure of multi-actor relationships are a response to complex, trans-border political, social, economic, and environmental challenges which require a more nuanced and varied management approach than narrowly defined state-led development. However, the power dynamics, the modalities, and experiences of engagement that underpin these dynamic relationships, remain understudied, especially with regard to their impact on sustainable development.

Abstract (sommario):
Objectives. To assess how to provide telehealth care by identifying characteristics of telehealth delivery, patient populations, settings, benefits and harms, and implementation strategies during the COVID-19 era. Data sources. PubMed®, CINAHL®, PsycINFO®, and the Cochrane Central Register of Controlled Trials were searched from March 2020 to May 2022. Additional studies were identified from reference lists and experts. Review methods. We included studies that reported characteristics of telehealth use; benefits and harms of telehealth; factors impacting the success of telehealth, including satisfaction/dissatisfaction and barriers/facilitators; and implementation outcomes. We conducted a mixed-methods review, synthesizing quantitative and qualitative studies. Two reviewers independently screened search results for eligibility, serially extracted data, and independently assessed risk of bias of included studies. Results. We included 764 studies; 310 studies were included in our syntheses. Patients using telehealth were more likely to be people who are young to middle-aged, female, White, of higher socioeconomic status, and living in urban settings. Visits for mental and behavioral health conditions were more frequent than visits for other conditions, and mental or behavioral care was also more likely to be delivered via telehealth than care for other conditions. Across a variety of conditions, telehealth produced similar clinical outcomes as compared with in-person care. Telehealth care is appropriate for some patients, but more information is necessary to determine the suitability of telehealth for specific patient populations; patients and providers felt that telehealth may be less suitable and less desirable for patients with complex clinical conditions; and some patients perceive telehealth as a barrier to improved health outcomes owing to the absence of a physical exam and challenges in developing rapport and communicating with their care team. There was a lack of evidence addressing implementation cost, penetration, and sustainability of telehealth, and about telehealth implementation at the health system level. Conclusions. Whereas telehealth use spiked after the beginning of the pandemic, the characteristics of patients using telehealth follow a pattern similar to that for other healthcare and digital health services. We found that the use of telehealth may be comparable to in-person care across different clinical and process outcomes. Telehealth implementation has addressed the needs of both patients and providers to some extent, even as clinical conditions, patient and provider characteristics, and type of assessment varied. Telehealth has provided a viable alternative mode of care delivery during the pandemic and holds promise for the future.

Abstract (sommario):
This research brief examines the interconnected challenges of climate change, environmental degradation (ED), and armed conflict. The brief highlights the complex relationships between natural resources, ED, and organised violence through multi-sited examples of habitat destruction, pollution, water scarcity, oil and gas-related conflicts, and deforestation. Every such fragile setting exhibits an intricate interwovenness of climate change and ED into the tapestry of sociopolitical and economic violence. Effectively addressing the causes of armed conflict influenced by environmental factors necessitates a contextualised understanding of this dynamic. The research brief also acknowledges the differential impacts of ED's consequences on marginalised populations while highlighting the potential for women to play a transformative role in addressing ED and insecurity.

Abstract (sommario):
This article examines a series of day laborer riots that occurred between 1959 and 1962 in Tokyo's largest day laborer district, Sanya. In doing so, it attempts to understand how local social changes were related to the riots. This paper argues that these riots represent a radical reaction on the part of Sanya's day laborers to the complex macroeconomic changes accompanying the era of high-speed growth. These changes, intimately related to the domestic construction industry, transformed Sanya into a profitable urban space in which capital could be invested and value generated.

Testo completo
Abstract (sommario):
This paper discusses recent trends in investment in the oil sector, amid new challenges for national and international oil companies in an increasingly supply-constrained environment. After more than a decade of stagnant investment rates, nominal investment has picked up sharply over the three years ending in 2007, but soaring costs (including from higher tax rates and royalties) meant that investment growth was minimal in real terms. The paper performs econometric tests using the Arellano-Bond GMM technique. It finds that `below ground¿ risks are statistically very important in deterring real investment. Companies are taking on increasingly complex geological challenges, which are putting upward pressure on production costs and are leading to greater project delays compared to the past. As many of these factors are expected to persist, supply constraints are likely to remain a dominant factor behind oil price fluctuations during the next several years.

Abstract (sommario):
Limited information exists about enrollment in Part D prescription coverage by Medicare beneficiaries with cancer. Part D coverage may increase access to medicines. This study evaluated patterns of Part D uptake and costs and assessed the effects of coverage on hospitalizations and emergency department (ED) use among people with colorectal cancer (CRC). We analyzed Surveillance, Epidemiology, and End Results (SEER)–Medicare linked data on fee-for-service (FFS) Medicare beneficiaries with at least 36 months of follow-up who were diagnosed with CRC at any point from January 2007 through December 2010, and a matched cohort of beneficiaries without cancer. Dual (Medicare/Medicaid) enrollees were excluded because they are automatically enrolled in Part D. Among beneficiaries with CRC (n=12,774), 39 percent had complete Part D coverage, defined as coverage in the diagnosis year and 2 subsequent years; the rate was 38 percent in the matched comparison cohort (P=.119). Among those with complete Part D coverage, there was no significant difference in annual prescription drug costs between people with CRC ($3,157, 95% confidence interval [CI]: $3,098–$3,216) and without ($3,113, 95% CI: $3,054–$3,172). Among people with CRC, odds of ED use ranged from unchanged to marginally higher for those with no or partial Part D coverage, (adjusted odds ratio: 1.09, 95% CI: 1.00–1.18), compared with those with complete Part D coverage. Lack of continuous Part D coverage was associated with more ED use among Medicare FFS beneficiaries with CRC in 2007–2013. Among people with Part D coverage, prescription drug costs varied little between those with CRC and matched beneficiaries without cancer.
