description: GeSn alloys have been regarded as a potential lasing material for a complementary metal-oxide-semiconductor (CMOS)-compatible light source. Despite their remarkable progress, all GeSn lasers reported to date have large device footprints and active areas, which prevent the realization of densely integrated on-chip lasers operating at low power consumption. Here, we present a 1D photonic crystal (PC) nanobeam with a very small device footprint of 7 $μm^2$ and a compact active area of ~1.2 $μm^2$ on a high-quality GeSn-on-insulator (GeSnOI) substrate. We also report that the improved directness in our strain-free nanobeam lasers leads to a lower threshold density and a higher operating temperature compared to the compressive strained counterparts. The threshold density of the strain-free nanobeam laser is ~18.2 kW cm$^{ -2}$ at 4 K, which is significantly lower than that of the unreleased nanobeam laser (~38.4 kW cm$^{ -2}$ at 4 K). Lasing in the strain-free nanobeam device persists up to 90 K, whereas the unreleased nanobeam shows a quenching of the lasing at a temperature of 70 K. Our demonstration offers a new avenue towards developing practical group-IV light sources with high-density integration and low power consumption.

description: We show theoretically that two atomic dipoles in a resonator constitute a non-linear medium, whose properties can be controlled through the relative position of the atoms inside the cavity and the detuning and intensity of the driving laser. We identify the parameter regime where the system operates as a parametric amplifier, based on the cascade emission of the collective dipole of the atoms, and determine the corresponding spectrum of squeezing of the field at the cavity output. This dynamics could be observed as a result of self-organization of laser-cooled atoms in resonators.

Cultural policy in Central Asia: comparative analysis of legislations and public policies
Creators: name: Smirnova, Svetlana
Publisher: name: IMT Alti Studi Lucca
Year: 2014
Subjects: NX Arts in general

description: This thesis provides an innovative and original contribution to the field of cultural policy research, critically assessing the public cultural
policies enforced in three Central Asian countries: Kazakhstan, Kyrgyzstan and Uzbekistan. Moving from the conceptual framework of system and lifeworld, this dissertation studies how
the Central Asian governments tend to colonize the cultural sphere intervening through legislative, financial and institutional measures. The first chapter looks at the concept of cultural
policy and related to it theories. The cultural policy refers to policies of diverse stakeholders that are directed to regulate or affect production and distribution of cultural goods and
services. This chapter considers first, the framework of Deulund P., based on the interplay of Habermasian concepts system and lifeworld and second, the types of governmental approach toward
the cultural sphere proposed by Hillman-Chartrand and McCaughey. The second chapter introduces the legislations of Kazakhstan, Kyrgyzstan and Uzbekistan in the cultural sphere. Identifying
the main similarities and differences this thesis argues that the main reason of similarities are Soviet legislation and regional integration processes. One of the sections argues that the
presidents of Kazakhstan and Uzbekistan possess central position in shaping the cultural policy. The third chapter after assessing the legal terms related to the cultural property, studies
the balance of the divergent interests (international, national, private) regarding the cultural property in the legislations of analyzed countries. The study is performed through the
analysis of two hypothetical cases (national vs. private) and dualism between cultural nationalism and cultural internationalism. The fourth chapter investigates the cultural decentralization
process, applying two analytical tools: the Type Function Framework and the Administrative Design Framework. There are two main conclusions emerged after collected data analysis. First,
Kazakhstan has embraced the most decentralized system, while the management of the cultural sphere in Uzbekistan is still largely based on a centralized decisionmaking. Second, all three
analyzed countries have adopted a strategy of Distributed Institutional Monopoly. Concluding, this thesis draws up a historical reconstruction of the administrative cultural policy-making
in independent Kazakhstan. The goal is to highlight how the structure of the ministry of culture, the public finance in the cultural sector, and the landscape of cultural organizations has
changed over the years. In this way, it has been possible to identify the trends of the cultural policy development in Kazakhstan as well as to critically evaluate the practical efficacy of the governmental strategy.

description: One of the most intriguing phenomena in physics is the localization of waves in disordered media. This phenomenon was originally predicted by Anderson, fifty years ago, in the context of transport of electrons in crystals. Anderson localization is actually a much more general phenomenon, and it has been observed in a large variety of systems, including light waves. However, it has never been observed directly for matter waves. Ultracold atoms open a new scenario for the study of disorder-induced localization, due to high degree of control of most of the system parameters, including interaction. Here we employ for the first time a noninteracting Bose-Einstein condensate to study Anderson localization. The experiment is performed with a onedimensional quasi-periodic lattice, a system which features a crossover between extended and exponentially localized states as in the case of purely random disorder in higher dimensions. Localization is clearly demonstrated by investigating transport properties, spatial and momentum distributions. We characterize the crossover, finding that the critical disorder strength scales with the tunnelling energy of the atoms in the lattice. Since the interaction in the condensate can be controlled at will, this system might be employed to solve open questions on the interplay of disorder and interaction and to explore exotic quantum phases.

subject: FOS: Chemical engineering

description: Disposal of sludge formed in both domestic and industrial wastewater treatment plants is one of the important problems waiting to be solved in Turkey and in the world. In recent years, sludge disintegration processes have emerged to eliminate the hydrolysis stage of biological stabilization processes. The disintegration of the sludge flocculation (sonodispergation effect) and the destruction of the cell membranes of the flocculating microorganisms are a direct effect of the ultrasonic disintegration of the sludge. This leads to the release of organic material and liquid sludge (sonolysis effect). Three main factors affect the ultrasonic disintegration of the sludge: applied energy, ultrasound frequency and sludge solid content. Ultrasonic disintegration technology solves solid phase and extracellular polymeric substance (EPS). As a result of this solubilization, sCOD increases. Ultrasonic disintegration affects both sludge dewaterability and microorganisms both negatively and positively. It has been found that sludge dewaterability increases at low energy levels, while filtration resistance increases significantly when high specific energy (ES) is applied. Microorganism concentrations increase at very low energy levels because US waves cause vibrations of water molecules, microorganisms, and other solutes in water. Sludge disintegration and cell dissolution occur at much higher energy levels. At ES> 32000 kJ/kg TKM, the number of intact bacteria begins to decrease due to death and/or dissolution of cells. Sonication also reduces pathogen and toxicity levels in the sludge. Moreover, the addition of US to other treatment processes has been found to produce a synergistic effect that significantly improves the degree of sludge disintegration (DD). For this reason and in terms of economic considerations, it was concluded in this paper that hybrid treatment technologies such as ultrasonic-alkaline treatment, ultrasonic-ozone, ultrasonic-Fenton and ultrasonic-photocatalytic technologies should be developed. This paper discusses in depth such promising and innovative technology, based on experimental results cited in the literature and current research lines, and demonstrates its advantages, disadvantages, and potential locations for its application in both wastewater treatment units and sludge treatment units.
The vibroacoustic behaviour of aerospace structures. Experimental measurements and simulations accounting for uncertainties
Creators: name: Polito, Tiziano
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: In static as well as dynamic design it is important to allow for the fact that uncertainties can exist in the properties of the designed system and in the applied loading.
Traditionally this has been faced through the use of factors of safety, which are developed and refined on the basis of experience and historical evidence. For systems
where efficient design is of the utmost importance (for example the minimum weight design of an aircraft structure) it is possible that the traditional factors of safety may be overly conservative, so that optimal efficiency cannot be achieved. Furthermore, historical factors of safety are unlikely to be appropriate for new design concepts or new composite materials. The properties of composites, in fact, present a scattering much higher than metals, mainly due to manufacturing and assembling process. It follows that there is a need for a method (or methods) that can be applied objectively to a new design to yield information on the safety and reliability of the system without reliance on established factors of safety. The principal aim of the present work is to investigate
capabilities offered by a probabilistic approach in the evaluation of vibroacoustic behaviour of aerospace composite damped panels. This is done interfacing probabilistic techniques with a numerical analysis of sound transmission loss. The numerical analysis, performed with a discrete coordinate approach, has been validated comparing simulation results with experimental ones measured in a dedicated facility, recently design and assembled, with the contribution of the author, at Department of Aerospace Engineering of the University of Naples “Federico II”.

description: We study the effective anisotropy induced in thin nanomagnets by the nonlocal demagnetization field (dipole-dipole interaction). Assuming a magnetization independent of the thickness coordinate, we reduce the energy to an inhomogeneneous onsite anisotropy. Vortex solutions exist and are ground states for this model. We illustrate our approach for a disk and a square geometry. In particular, we obtain good agreement between spin-lattice simulations with this effective anisotropy and micromagnetic simulations.

description: Today, there is a growing concern around the world for the development of alternative water reuse technologies that focus heavily on agriculture and industry. In this context, Advanced Oxidation Processes (AOPs) are considered as a highly competitive water treatment technology for the removal of organic contaminants that cannot be treated by conventional techniques due to its high chemical stability and/or low biodegradability. This paper reviews the literature on AOPs, presents data on the efficiency of these processes in pollutant degradation, and compares theoretical considerations and industrial applications. In this paper, the basics, main applications, advantages and disadvantages of AOPs (ozone-based, UV-based, electrochemical, catalytic and physical processes) were explained. AOPs have been recognized as a technically, economically and environmentally effective alternative for the degradation of pollutants in domestic and industrial wastewater, although they have limitations such as the high cost of available energy sources. New low-cost catalytic materials have been developed and full-scale reactors have been built. It is essential for İOPs to optimize the effectiveness of these factors for their industrial application.

description: We give a systematic account of unconstrained free bosonic higher-spin fields on D-dimensional Minkowski and (Anti-)de Sitter spaces in the frame formalism. The generalized spin connections are determined by solving a chain of torsion-like constraints. Via a generalization of the vielbein postulate these allow to determine higher-spin Christoffel symbols, whose relation to the de Wit--Freedman connections is discussed. We prove that the generalized Einstein equations, despite being of higher-derivative order, give rise to the AdS Fronsdal equations in the compensator formulation. To this end we derive Damour-Deser identities for arbitrary spin on AdS. Finally we discuss the possibility of a geometrical and local action principle, which is manifestly invariant under unconstrained higher-spin symmetries.

description: In typical microscopic approaches, particularly when pairing correlations are present, nuclei and nuclear fragments do not have well defined quantum numbers and symmetries should be restored. I present here a formalism for the simultaneous projection of total particle numbers of a nucleus, particle number of reaction fragments, and of the reaction fragment intrinsic spins and of their correlation, and also for their symmetry restored densities and total energies. These new formulas for the symmetry restored quantities, are free of any singularities, unlike those in the previously introduced prescriptions.

description: Iniciamos nuestro recorrido con el señalamiento de tres consensos para los lenguajes de la crítica en las humanidades en la escena actual de la teoría (Biset & Naranjo, 2022), a saber: el distanciamiento del giro lingüístico, la crítica de los dualismos ontológicos y la perturbación de las escalas. Para abrir la pregunta que guía este artículo, problematizamos el primer consenso, ése según el cual sería posible trazar una constante en los lenguajes actuales de la crítica que parecen distanciarse del giro lingüístico –específicamente de su versión posestructuralista–, discutiendo o bien su modo de comprender el lenguaje o bien el postulado de la mediación lingüística en tanto tal. Así, nuestra indagación busca ser una hoja de ruta para un posible camino que actualice la pregunta de la relación entre las palabras y las cosas desde una reformulación puntual: los signos y la materia. De ese modo, realizamos las siguientes acciones: sostenemos la hipótesis de un cierto retorno de las semejanzas desde la relectura de la prosa del mundo de Foucault y la lengua del mundo de Latour; revisamos qué nociones de signo (y sus vinculaciones con la imaginación crítica) están operando en las teorías contemporáneas; aislamos una batería de tácticas para la reorientación de lo escribible y lo legible en la escena teórico-crítica actual; finalmente, proponemos una serie de figuras desde las que balizamos el trabajo con los textos literarios desde una imaginación crítica singular.

description: We study a system of PDEs modeling the population dynamics of two competitive species whose spatial movements are governed by both diffusion and mutually repulsive chemotaxis effects. We prove that solutions to this system are globally well-posed, without any smallness assumptions on the chemotactic coefficients. Moreover, in the weak competition regime, we prove that neither species can be driven to extinction as the time goes to infinity, regardless of how strong the chemotaxis coefficients are. Finally, long-time behaviors of the system are studied both analytically in the weakly nonlinear regime, and numerically in the fully nonlinear regime.

Chirality of wave functions for three coalescing levels

description: The coalescence of three levels has particular attractive features. Even though it may be difficult to realise such event in the laboratory (three additional real parameters must be adjusted), to take up the challenge seems worthwhile. In the same way as the chiral behaviour of a usual EP can give a direction on a line, the state vectors in the vicinity of an EP3 provide an orientation in the plane. The distinction between left and right handedness depends on the distribution of the widths of the three levels in the vicinity of the point of coalescence.

description: A Hamiltonian approach to black hole entropy is used to study Riemannian Kerr-AdS solutions in the general, parity-violating Poincaré gauge theory. Entropy and the asymptotic charges are entirely determined by the parity-even sector of the theory, whereas the parity-odd contributions vanish. Entropy is found to be proportional to the horizon area, and the first law of black hole thermodynamics is confirmed.

description: Indirect resource competition and interference are widely occurring mechanisms of interspecific interactions. We have studied the seasonal expression of these two interaction types within a two-species, boreal small mammal system. Seasons differ by resource availability, individual breeding state and intraspecific social system. Live-trapping methods were used to monitor space use and reproduction in 14 experimental populations of bank voles Myodes glareolus in large outdoor enclosures with and without a dominant competitor, the field vole Microtus agrestis. We further compared vole behaviour using staged dyadic encounters in neutral arenas in both seasons. Survival of the non-breeding overwintering bank voles was not affected by competition. In the spring, the numbers of male bank voles, but not of females, were reduced significantly in the competition populations. Bank vole home ranges expanded with vole density in the presence of competitors, indicating food limitation. A comparison of behaviour between seasons based on an analysis of similarity revealed an avoidance of costly aggression against opponents, independent of species. Interactions were more aggressive during the summer than during the winter, and heterospecific encounters were more aggressive than conspecific encounters. Based on these results, we suggest that interaction types and their respective mechanisms are not either–or categories and may change over the seasons. During the winter, energy constraints and thermoregulatory needs decrease direct aggression, but food constraints increase indirect resource competition. Direct interference appears in the summer, probably triggered by each individual’s reproductive and hormonal state and the defence of offspring against conspecific and heterospecific intruders. Both interaction forms overlap in the spring, possibly contributing to spring declines in the numbers of subordinate species.

description: We analyze quantitatively the generation of a continuous beam of atoms by the periodic injection of individual packets in a guide, followed by their overlapping. We show that slowing the packets using a moving mirror before their overlapping enables an optimal gain on the phase space density of the generated beam. This is interpreted as a Maxwell's demon type strategy as the experimentalist exploits the information on the position and velocity of the center of mass of each packet.

description: Three dimensional topologically massive gravity (TMG) with a negative cosmological constant -\ell^{-2} and positive Newton constant G admits an AdS_3 vacuum solution for any value of the graviton mass μ. These are all known to be perturbatively unstable except at the recently explored chiral point μ\ell=1. However we show herein that for every value of μ\ell< 3 there are two other (potentially stable) vacuum solutions given by SL(2,R)x U(1)-invariant warped AdS_3 geometries, with a timelike or spacelike U(1) isometry. Critical behavior occurs at μ\ell=3, where the warping transitions from a stretching to a squashing, and there are a pair of warped solutions with a null U(1) isometry. For μ\ell>3, there are known warped black hole solutions which are asymptotic to warped AdS_3. We show that these black holes are discrete quotients of warped AdS_3 just as BTZ black holes are discrete quotients of ordinary AdS_3. Moreover new solutions of this type, relevant to any theory with warped AdS_3 solutions, are exhibited. Finally we note that the black hole thermodynamics is consistent with the hypothesis that, for μ\ell>3, the warped AdS_3 ground state of TMG is holographically dual to a 2D boundary CFT with central charges c_R={15(μ\ell)^2+81\over Gμ((μ\ell)^2+27)} and c_L={12 μ\ell^2\over G((μ\ell)^2+27)}.

description: In this note we perform a synopsis of the life-times from vacuum decay of several de Sitter vacuum constructions in string/M-theory which have a single dS minimum arising from lifting a pre-existing AdS extremum and no other local minima existent after lifting. For these vacua the decay proceeds via a Coleman--De Luccia instanton towards the universal Minkowski minimum at infinite volume. This can be calculated using the thin--wall approximation, provided the cosmological constant of the local dS minimum is tuned sufficiently small. We compare the estimates for the different model classes and find them all stable in the sense of exponentially long life times as long as they have a very small cosmological constant and a scale of supersymmetry breaking > TeV.

A yeast synthetic network for In-vivo Reverse-engineering and Modelling Assessment (IRMA)
Creators: name: Cantone, Irene
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: Systems Biology approaches aim to reconstruct gene regulatory networks from experimental data. Conversely, Synthetic Biology aims at using mathematical models to design novel biological ‘circuits’ (synthetic networks) in order to seed new functions inside the cell. These disciplines require quantitative mathematical models and reverse-engineering techniques.
A plethora of modelling strategies and reverse-engineering approaches has being proposed during the last years. Even if successful applications have being demonstrated, at present their usefulness and predictive ability cannot still be assessed and compared rigorously. There is the pressing and yet unsatisfied need for a ‘benchmark’: a perfectly known biological circuit that can be used to evaluate pro and cons of such techniques when applied at in vivo networks.
In order to address this aim, we constructed in the simplest eukaryotic organism, the yeast Saccharomyces cerevisiae, a novel synthetic network for In-vivo Reverse-engineering and Modelling Assessment (IRMA). IRMA is composed of five well-studied genes that have been assembled to regulate each other in such a way to include a variety of regulatory interactions, thus capturing the behaviour of larger eukaryotic gene networks on a smaller scale. It was designed to be isolated from the cellular environment, and to respond to galactose by triggering transcription of its genes.
To demonstrate that IRMA is a unique resource to validate the System and Synthetic biology approaches, we analysed the transcriptional response of IRMA genes following two different perturbation strategies: by performing a single perturbation and measuring mRNA changes at different time points, or by performing multiple perturbations and collecting mRNA measurements at steady state. We used these data as a ‘gold standard’ to assess either the predictive ability of mathematical modelling based on differential equations and, to compare four well-established reverse engineering algorithms, NIR, TSNI, BANJO and ARACNE.
We thus showed the usefulness of IRMA as the first simplified model of eukaryotic gene networks built “ad hoc” to test the power of network modelling and reverse-engineering strategies.

description: In today's dynamic business environment, technology is the most powerful tool to sustain in the competitive global marketplace. Companies are striving to improve their reliability, responsiveness, agility, and cost-effectiveness, thus enhancing their competitiveness by adopting new technologies. Integrating information technology into green logistics emerges as a strategic imperative for organizations seeking to enhance overall performance while addressing environmental concerns.

This paper aims to untangle the intricate connections between information technology and its significant impact on organizational performance through the implementation of green logistics management. To conceptualize these connections, a research model is developed to illustrate the relationship between these variables.

The exploration of connections in this study relies on a rigorous methodology. The foundation of this approach is the collection and in-depth examination of data derived from a wide array of scholarly resources.

The targum (1948:Sept. 17 - 1948:Sept. 28)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1948

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: The numerical integration of the Schrödinger equation by discretization of time is explored for the curved manifolds arising from finite representations based on evolving basis states. In particular, the unitarity of the evolution is assessed, in the sense of the conservation of mutual scalar products in a set of evolving states, and with them the conservation of orthonormality and particle number. Although the adequately represented equation is known to give rise to unitary evolution in spite of curvature, discretized integrators easily break that conservation, thereby deteriorating their stability. The Crank Nicolson algorithm, which offers unitary evolution in Euclidian spaces independent of time-step size $\mathrm{d}t$, can be generalised to curved manifolds in different ways. Here we compare a previously proposed algorithm that is unitary by construction, albeit integrating the wrong equation, with a faithful generalisation of the algorithm, which is, however, not strictly unitary for finite $\mathrm{d}t$.

SLE local martingales in logarithmic representations

description: A space of local martingales of SLE type growth processes forms a representation of Virasoro algebra, but apart from a few simplest cases not much is known about this representation. The purpose of this article is to exhibit examples of representations where L_0 is not diagonalizable - a phenomenon characteristic of logarithmic conformal field theory. Furthermore, we observe that the local martingales bear a close relation with the fusion product of the boundary changing fields. Our examples reproduce first of all many familiar logarithmic representations at certain rational values of the central charge. In particular we discuss the case of SLE(kappa=6) describing the exploration path in critical percolation, and its relation with the question of operator content of the appropriate conformal field theory of zero central charge. In this case one encounters logarithms in a probabilistically transparent way, through conditioning on a crossing event. But we also observe that some quite natural SLE variants exhibit logarithmic behavior at all values of kappa, thus at all central charges and not only at specific rational values.

description: Faunal remains from Palaeolithic sites are important genetic sources to study preglacial and postglacial populations and to investigate the effect of climate change and human impact. Post mortem decay, resulting in fragmented and chemically modified DNA, is a key obstacle in ancient DNA analyses. In the absence of reliable methods to determine the presence of endogenous DNA in sub-fossil samples, temporal and spatial surveys of DNA survival on a regional scale may help to estimate the potential of faunal remains from a given time period and region. We therefore investigated PCR amplification success, PCR performance and post mortem damage in c. 47,000 to c. 12,000-year-old horse remains from 14 Palaeolithic sites along the Swiss Jura Mountains in relation to depositional context, tissue type, storage time and age, potentially influencing DNA preservation. The targeted 75 base pair mitochondrial DNA fragment could be amplified solely from equid remains from caves and not from any of the open dry and (temporary) wetland sites. Whether teeth are better than bones cannot be ultimately decided; however, both storage time after excavation and age significantly affect PCR amplification and performance, albeit not in a linear way. This is best explained by the—inevitable—heterogeneity of the data set. The extent of post mortem damage is not related to any of the potential impact factors. The results encourage comprehensive investigations of Palaeolithic cave sites, even from temperate regions.

Progettazione, sintesi e studi conformazionali di peptidi attivi sul sistema urochinasi
Creators: name: Marcozzi, Cristina

description: L’Urochinasi (uPA) è una proteasi a serina coinvolta in alcuni processi di degradazione e di idrolisi sia in condizioni fisiologiche che patologiche. Esiste una forte correlazione tra l’invasività di alcune forme tumorali ed il livello di espressione di proteasi. Molti tumori umani presentano una incrementata espressione di urochinasi e del suo recettore (uPAR) che è correlata con un aumento dell’invasività del tumore.
L’uPA, legandosi al proprio recettore, innesca una interazione ligando dipendente tra l’ uPAR e l’integrina v5, in questo modo può promuovere riarrangiamenti nel citoscheletro e modulare la direzione della migrazione cellulare. L’uPA interagisce con l’integrina v5 anche in maniera diretta attraverso il dominio interno CP (Connecting Peptide).
L’attività di ricerca è stata incentrata sulla sintesi di polipeptidi correlati con l’urochinasi, al fine di valutare l’attività migratoria indotta su cellule umane embrionali di rene (HEK-293). Le sequenze aminoacidiche dei peptidi sintetizzati, sono derivate dal dominio CP dell’urochinasi umana: in particolare sono stati sintetizzati il polipeptide CPp, corrispondente alla sequenza del CP dell’urochinasi umana, e alcuni derivati di quest’ultimo progettati al fine di definire la minima sequenza attiva.
E’ stata inoltre presa in considerazione l’importanza del residuo amminoacidico Ser138 che, assieme al residuo di Ser303 dell’uPA, può essere sottoposto a fosforilazione. Tale modifica post-traduzionale non altera l’affinità per il recettore, ma modifica la risposta biologica producendo inibizione della migrazione cellulare. Sono stati quindi sintetizzati peptidi caratterizzati dalla sostituzione puntiforme del residuo di Ser138, con residui amminoacidici a catena laterale con carica negativa, al fine di valutare l’attività inibitoria della migrazione, nonché l’importanza della carica negativa per la strutturazione del peptide.
Il lavoro di sintesi è stato effettuato utilizzando la strategia sintetica in fase solida secondo la classica strategia via-Fmoc. Alla sintesi è seguita la relativa purificazione dei prodotti, tramite RP-HPLC preparativo con caratterizzazione mediante RP-HPLC analitico e spettrometria di massa ESI o MALDI. Sui composti più interessanti da un punto di vista farmacologico, è stata effettuata l’analisi conformazionale mediante tecniche CD ed NMR.
Keats and the dynamics of form

description: Of the many topics which have fascinated Keats's readers, three are remarkable for the continuing disputes they incite: the cause and nature of the prodigious and rapid development through which Keats firmly established himself in the ranks of great English poets in such an incredibly short time; Milton's influence on the Hyperion poems; and the origins of the distinctive Keatsian ode. The rapidity and extensiveness of Keats's development can be partially attributed to the process of discovery through writing which renders his earlier works the most important influence upon his later work. His ideas and his craftsmanship developed in tandem, enabling him to combine and alter traditional forms to suit his unique purposes — as, for example, he combines and modifies ode and sonnet forms to create odes which are innovative and unique. Nevertheless, Keats could not have soared to the heights he did in the short time he had, had Milton not preceded him. Although poets and dramatists have always reworked their predecessors' material in original ways, it was only from Milton that Keats could have learned not only to select appropriate traditional forms, but, also, to combine and modify those forms, and to adapt lyric forms as foundations upon which to build the blank verse of The Fall of Hyperion. Hence, Keats's process of development, his ode form, and the influence of Milton are integrally related, in fact, interdependent, and actually cannot be separated. However, to avoid repetition, I propose to discuss first Keats's growth in craftsmanship as it manifests itself in his development of the Keatsian ode, and then, to discuss Milton's influence on the Hyperion poems, particularly the ways in which Milton provides the model from which Keats effects startling changes in the blank verse of The Fall of Hyperion as compared to that of Hyperion — changes which are most dramatic in the segments which appear to be transposed directly from Hyperion.
