Explorando las carreras migratorias de mujeres brasileñas en España: reconceptualización de la adecuación entre formación y trabajo
Creators: name: Di Martino, Maria Luisa
Publisher: name: Confluenze. Rivista di Studi Iberoamericani
Year: 2023

description: Este trabajo analiza las ‘carreras migratorias’ de un grupo de mujeres altamente formadas de origen brasileño y las dinámicas activadas para conseguir la adecuación entre formación y trabajo en España. Para ello, se exploran las razones de emigración y arraigo, y las estructuras de obstáculos y oportunidades, desde una perspectiva multidimensional. Los resultados muestran la existencia de un sistema de vulnerabilidades, que influencia tanto las trayectorias geográficas como las (in)movilidades profesionales, y que se encuentra explicado en la interconexión de factores que limitan o fomentan el desarrollo de una carrera profesional balanceada con las aspiraciones personales y conseguir un trabajo encajado.

description: This article deals with the numerical modeling of the pulsating heat pipe (PHP) and is based on the film evaporation/condensation model recently applied to the single-bubble PHP (Das et al., 2010, "Thermally Induced Two-Phase Oscillating Flow Inside a Capillary Tube," Int. J. Heat Mass Transfer, 53(19--20), pp. 3905--3913). The described numerical code can treat the PHP of an arbitrary number of bubbles and branches. Several phenomena that occur inside the PHP are taken into account: coalescence of liquid plugs, film junction or rupture, etc. The model reproduces some of the experimentally observed regimes of functioning of the PHP such as chaotic or intermittent oscillations of large amplitudes. Some results on the PHP heat transfer are discussed.
Periodic points of rational area-preserving homeomorphisms

description: An area-preserving homeomorphism isotopic to the identity is said to have rational rotation direction if its rotation vector is a real multiple of a rational class. We give a short proof that any area-preserving homeomorphism of a compact surface of genus at least two, which is isotopic to the identity and has rational rotation direction, is either the identity or has periodic points of unbounded minimal period. This answers a question of Seyfaddini and can be regarded as a Conley conjecture-type result for symplectic homeomorphisms of surfaces beyond the Hamiltonian case. We also discuss several variations, such as maps preserving arbitrary Borel probability measures with full support, maps not isotopic to the identity, and maps on lower genus surfaces. The proofs of the main results combine topological arguments with periodic Floer homology.

description: En este artículo nos propusimos examinar los vínculos personales y políticos establecidos entre el presidente Juan Domingo Perón y monseñor Nicolás De Carlo, obispo de la diócesis de Resistencia (Chaco, Argentina). Entre los años 1946 y 1951, este sacerdote se convirtió uno de los referentes de la jerarquía eclesiástica argentina más cercano al gobierno con el que tuvo muchas coincidencias que le valieron reconocimiento, pero, al mismo tiempo, el encono de algunos de sus pares. A través de este análisis buscamos indagar en la participación de sectores de la Iglesia en el proceso de construcción del peronismo en espacios periféricos del país.

description: El cine musical español fue habitual durante el franquismo, con actores que cantaban o con cantantes que actuaban. Vinculado en un principio a estilos populares, apostó desde los años 60 por la canción melódica o el pop, y fomentó una idea de modernidad ante Europa y Latinoamérica mediante los cantantes del momento. Este artículo analiza los personajes y las canciones de las siete películas que Raphael protagonizó entre 1966 y 1973, en el segundo franquismo, donde interpretó, casi de forma autobiográfica, a aspirantes y a estrellas, cantó los éxitos de sus discos y sus actuaciones funcionan a modo de videoclip.

description: Detection of the September maximum in the primary near-Earth daemon flux at high (~60o) Northern latitudes by our set-up with a plane horizontal scintillator is plagued by purely geometric factors; indeed, because of the Earth's rotation axis being tilted, the daemons catching up with the Earth in outer Near-Earth, Almost Circular Heliocentric Orbits (NEACHOs) strike the Earth along close-to-horizontal paths. Nevertheless, application of only two oppositely oriented, specially designed "dark electron multipliers" of the type TEU-167d (only their dia.125-mm front disc is coated on the inside by a thick, ~0.5 um Al layer, which permits such multipliers to detect primarily daemons flying inside them from the base to the disc) has made it possible for us to detect in one experiment, at a confidence level of >3 sigma, a flux of daemons captured from NEACHOs into Geocentric Earth-Surface-Crossing Orbits, as well as to record a decrease in the velocity of these objects from ~10 to ~7 km/s in a characteristic time of ~1 month resulting from their being slowed down in transits through the Earth's body.

Neste caso, valer-nos-emos da restante sermonística de Vieira, assim como dos trabalhos de Hansen e Pécora, para exibir sua relação com a decisão do Concílio de Trento de não guerrear, mas incluir o gentio para correção, o que nos fará concluir que a inclusão da voz tem função domesticadora.

Characterization of a naphthalene dioxygenase endowed with an exceptionally broad substrate specificity toward polycyclic aromatic hydrocarbons

description: In Sphingomonas CHY-1, a single ring-hydroxylating dioxygenase is responsible for the initial attack of a range of polycyclic aromatic hydrocarbons (PAHs) composed of up to five rings. The components of this enzyme were separately purified and characterized. The oxygenase component (ht-PhnI) was shown to contain one Rieske-type [2Fe-2S] cluster and one mononuclear Fe center per alpha subunit, based on EPR measurements and iron assay. Steady-state kinetic measurements revealed that the enzyme had a relatively low apparent Michaelis constant for naphthalene (Km= 0.92 $\pm$ 0.15 $μ$M), and an apparent specificity constant of 2.0 $\pm$ 0.3 $μ$M-1 s-1. Naphthalene was converted to the corresponding 1,2-dihydrodiol with stoichiometric oxidation of NADH. On the other hand, the oxidation of eight other PAHs occurred at slower rates, and with coupling efficiencies that decreased with the enzyme reaction rate. Uncoupling was associated with hydrogen peroxide formation, which is potentially deleterious to cells and might inhibit PAH degradation. In single turnover reactions, ht-PhnI alone catalyzed PAH hydroxylation at a faster rate in the presence of organic solvent, suggesting that the transfer of substrate to the active site is a limiting factor. The four-ring PAHs chrysene and benz[a]anthracene were subjected to a double ring-dihydroxylation, giving rise to the formation of a significant proportion of bis-cis-dihydrodiols. In addition, the dihydroxylation of benz[a]anthracene yielded three dihydrodiols, the enzyme showing a preference for carbons in positions 1,2 and 10,11. This is the first characterization of a dioxygenase able to dihydroxylate PAHs made up of four and five rings.

Subjects: Plastic pollution, plant-derived polysaccharides, pectin, starch, carrageenan, biodegradable, edible films

description: Plastic pollution is a major, pressing, global concern. Every year, coastal nations dispose 8 million tons of plastic waste into the oceans. This figure equates to setting five rubbish bags full of trash on every foot of coastline around the world. Millions of animals are killed and sickened by plastics every year, from birds to fish and other marine organisms. Plastic residues are found in nearly all species of seabirds. To address this global catastrophe, alternatives to fossil fuel-derived plastics must be developed and made cheaper and more accessible to all. There is a possibility that using plant-derived polysaccharides such as starch and pectin, and seaweed-derived carrageenan in food packaging might work after processing them into films. One inspiration for this is the food packaging made from seaweed, a concept that started in Indonesia. Plant-derived polysaccharides turned into food packaging can also be halal-certified, safe to eat, and nutritious, containing high fibre and nutrients. In addition, they are biodegradable, addressing the issue of plastics enroaching our most fragile ecosystems. These plant-derived films can also be turned into collagen for medical uses. One of the aims of this project is to devise, develop, and optimise environmentally safe and facile methods of producing edible and biodegradable food packaging material and collagen for medical uses from starch, pectin, and other plant-based polysaccharides derived from food wastes, and analyse their bio/physical properties.

description: We present a mean-field dynamical theory for single semiflexible polymers which can precisely capture, without fitting parameters, recent fluorescence correlation spectroscopy results on single monomer kinetics of DNA strands in solution. Our approach works globally, covering three decades of strand length and five decades of time: it includes the complex cross-overs occurring between stiffness-dominated and flexible bending modes, along with larger-scale rotational and center-of-mass motion. The accuracy of the theory stems in part from long-range hydrodynamic coupling between the monomers, which makes a mean-field description more realistic. Its validity extends even to short, stiff fragments, where we also test the theory through Brownian hydrodynamics simulations.

The mathematical model includes the dynamic of Dengue mosquito, the affected persons, the people's motivation to combat the mosquito and the inherent social cost of the disease, such as cost with ill individuals, educations and sanitary campaigns. The dynamic model presents a set of nonlinear ordinary differential equations. The problem was discretized through Euler and Runge Kutta schemes, and solved using nonlinear optimization packages. The computational results as well as the main conclusions are shown.

description: In 1992 Wang & Larsen extended the may- and must preorders of De Nicola and Hennessy to processes featuring probabilistic as well as nondeterministic choice. They concluded with two problems that have remained open throughout the years, namely to find complete axiomatisations and alternative characterisations for these preorders. This paper solves both problems for finite processes with silent moves. It characterises the may preorder in terms of simulation, and the must preorder in terms of failure simulation. It also gives a characterisation of both preorders using a modal logic. Finally it axiomatises both preorders over a probabilistic version of CSP.

This enables remote coincidence identification in entanglement-based quantum key distribution schemes without dedicated coincidence hardware, pulsed sources with a timing structure or very stable reference clocks. We discuss the method for typical operating conditions, and show that the requirement in reference clock accuracy can be relaxed by about 5 orders of magnitude in comparison with previous schemes.

The biosynthesis of N-putrescinylthymine in bacteriophage φW-14 infected Pseudomonas acidovorans
Creators: name: Karrer, Earl
Publisher: name: University of British Columbia
Year: 2011

description: The biosynthesis of N-putrescinylthymine (NpT), a modified pyrimi-dine which occurs in the DNA of phage φW-14, was studied. Prior to this study, the metabolism of arginine and polyamines in the host organism, Pseudomonas acidovorans 29, was investigated. P. acidovorans transported ornithine and arginine but not putrescine. Neither amino acid was used as a sole source of nitrogen. Thus arginine cannot be catabolized to putrescine and ornithine is not catabolized to γ-aminobutyrate. Ornithine was synthesized from glutamate but the operation of this pathway was not inhibited by high concentrations of arginine. Since ornithine was decarboxylated to putrescine, this single route for the synthesis of polyamines is unusual in that ornithine biosynthesis is constitutive. P. acidovorans and φW-14 contain an unusual complement of polyamines: spermidine, putrescine and 2-hydroxyputrescine. Their respective bacterial concentrations (mM) were: 3-5, 50 and 45, phage infection led to an increase in the proportion of putrescine. ¹⁴C-Ornithine was used to label NpT in phage DNA. ¹⁴C-5-Ornithine exclusively labelled NpT, whereas ¹⁴C-1-ornithine was totally ineffective in this capacity. Hence, the carboxyl group of ornithine is not a constituent of the NpT molecule. Labelling of NpT with ¹⁴C-3-serine demonstrated a tetrahydrofolate (THF) involvement in its biosynthesis. The use of ³H-2,3-serine showed that N¹⁰methylene THF was the carbon donor for the pyrimidine precursor of NpT. It is proposed that NpT is synthesized in the following way: 5-hydroxymethyl deoxyuridine monophosphate is formed by the interaction of N¹⁰ methylene THF and deoxyuridine monophosphate; putrescine then condenses with the hydroxymethyl group of the nucleotide to yield N-putrescinyl-thymine.

description: Measuring similarity of neural networks to understand and improve their behavior has become an issue of great importance and research interest. In this survey, we provide a comprehensive overview of two complementary perspectives of measuring neural network similarity: (i) representational similarity, which considers how activations of intermediate layers differ, and (ii) functional similarity, which considers how models differ in their outputs. In addition to providing detailed descriptions of existing measures, we summarize and discuss results on the properties of and relationships between these measures, and point to open research problems. We hope our work lays a foundation for more systematic research on the properties and applicability of similarity measures for neural network models.

Our main emphasis is the interpretation of that fragmentation as due to particle-vibration coupling (PVC). We compare with recent Energy Density Functional (EDF) approaches, and try to present a critical perspective.

description: We experimentally demonstrate and numerically simulate a new adaptive method to maintain synchronization between coupled nonlinear chaotic oscillators, when the coupling between the systems is unknown and time-varying (e.g., due to environmental parameter drift). The technique is applied to optoelectronic feedback loops exhibiting high dimensional chaotic dynamics. In addition to keeping the two systems isochronally synchronized in the presence of a priori unknown time-varying coupling strength, the technique provides an estimate of the time-varying coupling.

description: Simulations of scanning tunneling microscopy measurements for molecules on surfaces are traditionally based on a perturbative approach, most typically employing the Tersoff-Hamann method. This assumes that the STM tip is far from the sample so that the two do not interact with each other. However, when the tip gets close to the molecule to perform measurements, the electrostatic interplay between the tip and substrate may generate non-trivial potential distribution, charge transfer and forces, all of which may alter the electronic and physical structure of the molecule. These effects are investigated with the ab initio quantum transport code SMEAGOL, combining non-equilibrium Green's functions formalism with density functional theory. In particular, we investigate alkanethiol molecules terminated with either CH3 or CF3 end-groups on gold surfaces, for which recent experimental data are available. We discuss the effects connected to the interaction between the STM tip and the molecule, as well as the asymmetric charge transfer between the molecule and the electrodes.

description: We introduce and begin to study Lie theoretical analogs of symplectic reflection algebras for a finite cyclic group, which we call "cyclic double affine Lie algebra". We focus on type A : in the finite (resp. affine, double affine) case, we prove that these structures are finite (resp. affine, toroidal) type Lie algebras, but the gradings differ. The case which is essentially new involves $\mathbb{C}[u,v]$. We describe its universal central extensions and start the study of its representation theory, in particular of its highest weight integrable modules and Weyl modules. We also consider the first Weyl algebra $A_1$ instead of the polynomial ring $\mathbb{C}[u,v]$, and, more generally, a rank one rational Cherednik algebra. We study quasi-finite highest weight representations of these Lie algebras.

description: (Abridged). We present HST photometry of the late-type dwarf galaxy NGC 1705 observed with the WFPC2 in the U and B bands, and with the ACS/HRC in the U, V, and I bands. We cross-correlate these data with previous ones acquired with the WFPC2 in V and I and derive multiband Color-Magnitude diagrams (CMDs) of the cross-identified individual stars and candidate star clusters. For the central regions of the galaxy, where HST-NICMOS J and H photometry is also available, we present U, B, V, I, J, H CMDs of the 256 objects with magnitudes measured in all bands. While our previous study based on V, I, J and H data allowed us to trace the star formation history of NGC 1705 back to a Hubble time, the new data provide a better insight on its recent evolution. With the method of the synthetic CMDs, we confirm the presence of two strong bursts of star formation (SF). The older of the two bursts (B1) occurred between ~ 10 and 15 Myr ago, while the younger burst (B2) started ~ 3 Myr ago, and it is still active. The stellar mass produced by B2 amounts to ~ 10^6 msun, and it is a factor of ~ 3 lower for B1. The interburst phase was likely characterized by a much lower level of SF rather than by its complete cessation. The two bursts show distinct spatial distributions: while B1 is centrally concentrated, B2 is more diffused, and presents ring and arc-like structures that remind of an expanding shell. This suggests a feedback mechanism, in which the expanding superbubble observed in NGC 1705, likely generated by the (10-15) Myr burst, triggered the current strong SF activity. From the HRC data, we identified 12 star clusters (plus the SSC) in the central region of NGC 1705, 10 of which have photometry in all the UBVIJH bands. Using the GALEV models, we derived ages from ~ 10 Myr to ~ 1 Gyr, and masses between ~ 10^4 and 10^5 msun for the clusters.

title: A Brand New Bond: Shifting Strategies for 007 in the Age of Conglomeration and Convergence

description: Financial success would seem to be the logical goal of the film industry. If the current narrative formula reaps financial rewards for a film franchise there should be no impetus for change. Yet, that is exactly what happened to the James Bond franchise in 2006, with the release of the prequel Casino Royale. Sony Corporation and the Bond film :franchise traversed similar paths. In 2005, Sony purchased MGM, which held the Bond library as well as the rights to future Bond film productions.

Sony's industrial needs differed greatly from MGM's. MGM continually recycled the Bond formula for 20 films for over 40 years, with great box office success. However, for Sony, box office receipts alone would not provide enough profit. Sony needed Bond to travel across its multiple holdings creating a synergistic convergence of its hardware and its software ( content). In doing so, Sony gambled that Bond would provide the buzz necessary for consumers to purchase the Blu-ray player and DVDs, as well as videogames. Bond's history of high-end merchandise, such as automobiles, watches and alcohol, enticed Sony even more. If fans would purchase those items, they could be persuaded to purchase the Blu-ray series as well.

In order for Sony to garner increased investment, financially and emotionally, from a larger Bond audience, it needed a shift in the previous Bond formula. Aesthetically, the new film looked edgier and grittier, but more importantly, the narrative strategy increased the Bond storyworld, deepening the understanding of Bond and offering a new lens in which to see Bond, past, present and future.

Through the use of intertextual references and the paratext, Casino Royale provided a new Bond. This thesis combines industrial analysis of convergence and conglomeration with narrative strategies of serialization, deepening storyworld and management of intertextual references. The intersection of Sony and Bond in Casino Royale provides an excellent example of the influence industrial context has on narrative strategies.

description: We consider a Boussinesq system describing one-dimensional internal waves which develop at the boundary between two immiscible fluids, and we restrict to its traveling waves. The method which yields explicitly all the elliptic or degenerate elliptic solutions of a given nonlinear, any order algebraic ordinary differential equation is briefly recalled. We then apply it to the fluid system and, restricting in this preliminary report to the generic situation, we obtain all the solutions in that class, including several new solutions.

Physics of radio emission in the long-period pulsars

description: Recent multi-frequency measurements of pulse widths W50 for the long-period pulsar J0250+5854 by Agar et al provide a unique insight to the emission process owing to its small polar-cap radius. The frequency-dependence of W50 can be simply understood as a consequence of the emitting plasma remaining under acceleration during the interval of radio emission. This is possible in a plasma of ions and protons but not in one of high-multiplicity electron-positron pairs. Extension of the model to the pulse profiles of the general pulsar population is considered briefly.

description: The masses of the lowest-lying states in the meson and in the gluonic sector of an SU(2) gauge theory with two Dirac flavors in the adjoint representation are measured on the lattice at a fixed value of the lattice coupling $β= 4/g_0^2 = 2.25$ for values of the bare fermion mass $m_0$ that span a range between the quenched regime and the massless limit, and for various lattice volumes. Even for light constituent fermions the lightest glueballs are found to be lighter than the lightest mesons. Moreover, the string tension between two static fundamental sources strongly depends on the mass of the dynamical fermions and becomes of the order of the inverse squared lattice linear size before the chiral limit is reached. The implications of these findings for the phase of the theory in the massless limit are discussed and a strategy for discriminating between the (near--)conformal and the confining scenario is outlined.

description: We report the synthesis and superconducting properties of a layered cage compound Ba3Rh4Ge16. Similar to Ba3Ir4Ge16, the compound is composed of 2D networks of cage units, formed by noncubic Rh-Ge building blocks, in marked contrast to the reported rattling compounds. The electrical resistivity, magnetization, specific heat capacity, and muSR measurements unveiled moderately coupled s-wave superconductivity with a critical temperature Tc = 7.0 K, the upper critical field ~ 2.5 T, the electron-phonon coupling strength ~ 0.80, and the Ginzburg-Landau parameter ~ 7.89. The mass reduction by the substitution of Ir by Rh is believed to be responsible for the enhancement of Tc and coupling between the cage and guest atoms. Our results highlight the importance of the atomic weight of the framework in cage compounds in controlling the electron-phonon coupling strength and Tc.

description: Trialeurodes dicksoniae Martin, 1999 DISTRIBUTION. Australia (Victoria), New Zealand. HOST PLANTS. Dicksoniaceae: Dicksonia antarctica; D. squarrosa. COMMENTS. The type sample was collected from tree ferns in the Eucalyptus forest of Tall Trees National Park in Australia. Whitefly puparial specimens have recently been collected on a different Dicksonia species in New Zealand (R. Henderson, NZAC, personal communication), and examination reveals that a small proportion of these specimens are identical to those of Australian T. dicksoniae. However, the majority of specimens from the same sample match material in BMNH, collected by Dumbleton and determined as T. asplenii: if these other specimens are indeed T. asplenii it is considered possible that T. dicksoniae will later prove to be its synonym.

description: We consider unambiguous identification of coherent states of electromagnetic field. In particular, we study possible generalizations of an optical setup proposed in M. Sedlák {\it et al.}, Phys. Rev. A {\bf 76}, 022326 (2007). We show how the unambiguous identification of coherent states can be performed in a general case when multiple copies of unknown and the reference states are available. We also investigate whether reference states after the measurement can be "recovered" and further used for subsequent unambiguous identification tasks. We show that in spite of the fact that the recovered reference states are disturbed by measurements they can be repeatedly used for unambiguous identifications. We analyze the role of various imperfections in preparation of the unknown and the reference coherent states on the performance of our unambiguous identification setup.

The information about the state of a qubit gained by a weakly coupled detector

description: We analyze the information that one can learn about the state of a quantum two-level system, i.e. a qubit, when probed weakly by a nearby detector. In particular, we focus on the case when the qubit Hamiltonian and the qubit's operator being probed by the detector do not commute. Because the qubit's state keeps evolving while being probed and because the measurement data is mixed with a detector-related background noise, one might expect the detector to fail in this case. We show, however, that under suitable conditions and by proper analysis of the measurement data useful information about the state of the qubit can be extracted. It turns out that the measurement basis is stochastically determined every time the experiment is repeated. We analyze in detail the probability distributions that govern the choice of measurement bases. We also analyze the information acquisition rate and show that it is largely unaffected by the apparent conflict between the measurement and intrinsic qubit dynamics. We discuss the relation between our analysis and the stochastic master equation that describes the evolution of the qubit's state under the influence of measurement and decoherence. In particular, we write down a stochastic equation that encompasses the usual stochastic master equation for the evolution of the qubit's density matrix and additionally contains the measurement information that can be extracted from the observed signal.
