description: In der Asphaltproduktion wird ein großer Teil der Energie wegen der hohen Temperatu-ren für die Mischgutherstellung verwendet. Das Problem gilt verstärkt für Gussasphalt, da die Temperaturen für die Verarbeitung bei 220 250 C liegen. Die Erniedrigung dieser Temperaturen führt zu mehr Energieeffizienz und zur Herabsetzung der Treibhausgas-Emissionen in der Asphaltproduktion. Ziel der Forschung ist die Optimierung von Gussasphaltmischgütern bei maximaler Tem-peraturabsenkung und bei gleichbleibend hoher Qualität zum Einsatz als Garagenbefes-tigung. Dafür wurde das Gussasphaltmischgut mit Rundkorn und Amidwachs optimiert und dessen Gebrauchsverhalten mittels Prüfmethoden im Labor untersucht. Die Prüfmethoden innerhalb dieser Arbeit unterteilen sich in Verarbeitbarkeit und GVO-Prüfungen. Für die Bestimmung der Verarbeitbarkeit von Gussasphalt wird die Drehmo-mentmessung und der Ausbreitversuch verwendet. Die angewendeten GVO-Prüfungen sind die Abkühlprüfung (TSRST) und die einaxiale, zyklische Druckschwellprüfung (UCCT). Die Ergebnisse zeigen, dass durch die Optimierung gute Verarbeitbarkeit bei bis zu 50 K niedrigeren Temperaturen realisierbar ist. Weiterhin führt die Optimierung nicht zur Ver-ringerung des Risswiderstands, jedoch wird die Verformungswiderstandsfähigkeit erhöht.
description: The production process of asphalt involves a considerable amount of energy consump-tion because of the high temperatures required for the mixture process. This issue gains importance, especially when considering mastic asphalt, for which production tempera-tures up to 220 250 C. Decreasing these temperatures could lead to more energy effi-ciency and reduction of the greenhouse gases (GHG) in the asphalt mixing plant. Aim of the research is the optimization of mastic asphalt mixes by maximum decrease of the temperature and by constantly high performance for the application of garage pave-ments. For that reason, the mastic asphalt mixture is optimized with rounded aggregates and amide wax and its performance is examined with the help of laboratory testing meth-ods. The applied testing methods within this thesis are divided into workability and perfor-mance based tests. The investigation of the workability is achieved by means of torque measurement and flow table test. The performance based tests, applied in the course of this work, are the tensile stress restrained specimen test (TSRST) and uniaxial cyclic compression test (UCCT). The results show that through optimization a good workability at reduced temperatures (-50 K) can be accomplished. Furthermore, the optimization doesn`t affect the low-temperature resistance and still satisfactory resistance at the high temperature range can be observed.

Kinetics of destruction of potato polyphenol oxidase (PPO) during vacuum microwave blanching

description: Vacuum microwave (VM) blanching decreases enzymatic food browning at low temperatures (between ~40-55°C) when compared to conventional processing methods. The impact and reaction of microwave blanching on polyphenol oxidase (PPO) of the Russet potato was investigated and compared with the effects of conventional convective heating. In order to closely examine PPO kinetics in a microwave field and to establish a PPO assay for use in further investigations, potato puree plus polyvinylpolypyrrolidone (PVPP) was centrifuged and filtered to produce a treatment ready suspension. Whole potatoes were cut into French fry strips and blanched using a pilot-sized V M dehydrator. This was compared to a steam kettle blanch to determine the blanch effects on physical form. Finally, two different microwave treatments were utilized along with a heated water bath in order to compare the microwave heated potato suspension samples with conventional heating. Microwave treatments used a 700 W, 2450 MHz vacuum microwave oven and an Ethos Synth (ES-MR) microwave reactor set at 2450 MHz, which dropped the microwave power level from 700 W to below 100 W after reaching the desired temperature. Experiments in all three treatments were conducted under controlled temperatures between 40°C and 70°C. The decimal reduction values (D-value) of PPO were reduced by heating in vacuum microwave treatments as compared to heating in a water bath at temperatures between 40°C and 57°C. At these temperatures, the D-values, z-values and activation energies (E[sub a]) for the PPO model reaction were significantly lower (p < 0.05) for the VM and the ES than the heated water bath. The results suggest the existence of an alternative inactivation mechanism for PPO when heated in a microwave field compared to a water bath at low processing temperatures.

description: A detection of the stochastic gravitational-wave background (SGWB) from unresolved compact binary coalescences could be made by Advanced LIGO and Advanced Virgo at their design sensitivities. However, it is possible for magnetic noise that is correlated between spatially separated ground-based detectors to mimic a SGWB signal. In this paper we propose a new method for detecting correlated magnetic noise and separating it from a true SGWB signal. A commonly discussed method for addressing correlated magnetic noise is coherent subtraction in the raw data using Wiener filtering. The method proposed here uses a parameterized model of the magnetometer-to-strain coupling functions, along with measurements from local magnetometers, to estimate the contribution of correlated noise to the traditional SGWB detection statistic. We then use Bayesian model selection to distinguish between models that include correlated magnetic noise and those with a SGWB. Realistic simulations are used to show that this method prevents a false SGWB detection due to correlated magnetic noise. We also demonstrate that it can be used for a detection of a SGWB in the presence of strong correlated magnetic noise, albeit with reduced significance compared to the case with no correlated noise. Finally, we discuss the advantages of using a global three-detector network for both identifying and characterizing correlated magnetic noise.

description: Große Mengen Nahrungsmittel werden in genusstauglichem Zustand durch den Lebensmitteleinzelhandel (LEH) im Müll entsorgt. Die sogenannte Container-Szene hat sich zum Ziel gesetzt, diese aussortierten Lebensmittel zu verwerten. „Containern“ (auch „Dumpstern“ oder „Mülltauchen“) bezeichnet demnach eine Handlung, bei der Müllcontainer nach noch verzehrbaren Nahrungsmitteln durchsucht werden. Die Szene verzeichnet einen verstärkten Zulauf von überwiegend jungen Menschen. Bislang ist wenig über die genauen Motive der beteiligten Personen bekannt. Dieser Beitrag explorativen Charakters beschäftigt sich daher mit der individuellen Motivation der Göttinger MülltaucherInnen, die in leitfadengestützten Interviews zu ihren Container-Aktivitäten befragt wurden. Es zeigt sich, dass eigennützige Beweggründe, wie z.B. die finanzielle Ersparnis, nur eine untergeordnete Rolle für die Interviewten spielen. Hauptmotive sind, die Öffentlichkeit und das persönliche Umfeld für das Thema Lebensmittelverluste zu sensibilisieren sowie an den LEH zu appellieren, die Verluste zu verringern. Ferner spielt die direkte Reduktion der Verluste, das ‚Retten‘ der Lebensmittel, eine Rolle. Die qualitativen Ergebnisse werden vor dem Hintergrund der bisher vorhandenen Literatur zur Container-Szene diskutiert und eine Verknüpfung zu gesellschaftlichen Bewegungen allgemein sowie zur Solidarischen Landwirtschaft hergestellt.

description: (abridged) Studies of distant galaxies have shown that ellipticals and large spirals were already in place 8 Gyr ago, leading to a very modest recent star formation in intermediate mass galaxies. This is challenged by a recent analysis (Heavens et al. 2004) of the fossil record of the stellar populations of ~10^5 nearby galaxies, which show that intermediate mass galaxies have formed or assembled the bulk of their stars 4 to 8 Gyr ago. Here we present direct observational evidence supporting the Heavens et al's findings from a long term, multi-wavelength study of 195 z>0.4 intermediate mass galaxies, mostly selected from the CFRS survey. We show that a recent and efficient star formation is revealed at IR wavelengths since ~15% of intermediate mass galaxies at z>0.4 are indeed luminous IR galaxies (LIRGs), a phenomenon far more common than in the local Universe. The star formation in LIRGs is sufficient in itself to produce 38% of the total stellar mass of intermediate mass galaxies and then to account for most of the reported stellar mass formation since z=1. The high occurrence of LIRGs is easily understood only if they correspond to episodic peaks of star formation, during which galaxies are reddened through short IREs (infrared episodes). We examine how galaxy IREs can be related to the emergence at high redshift, of the abundant population of galaxies with small size, blue core and many irregularities. We show that recent merging and gas infall naturally explain both morphological changes and episodic star formation history in a hierarchical galaxy formation frame. We propose a simple scenario in which 75+-25% of intermediate mass spirals have experienced recently their last major merger event, leading to a drastic reshaping of their bulges and disks during the last 8 Gyrs.

description: We have measured temperature-dependent magnetic Compton profiles (MCPs) from a single crystal of La$_{1.2}$Sr$_{1.8}$Mn$_2$O$_7$. The MCPs, which involved the scattering of circularly polarized x-rays, are in general related to the momentum density of all the unpaired spins in the system. Nevertheless, we show that when the x-ray scattering vector lies along the [110] direction, the number of magnetic electrons of a specific symmetry, i.e. $d$-electrons of $x^2-y^2$ symmetry, yield a distinct signature in the MCP, allowing us to monitor substantial changes in the occupancy of the $d_{x^2-y^2}$ states over the investigated temperature range of 5-200K. This study indicates that magnetic Compton scattering can provide a powerful window on the properties of specific magnetic electrons in complex materials.

Ziel der Studie ist es, die Auswirkungen des EU-Quotenausstiegs auf den Zucker- und Isoglukosemarkt quantitativ abzuschätzen. Dazu werden die Markteffekte einer Aufhebung der Produktionsquoten mithilfe eines räumlichen Preisgleichgewichtsmodells für drei Weltmarktpreisszenarien analysiert. Die Ergebnisse zeigen, dass in einigen EU-Mitgliedstaaten die zukünftige Weltmarktpreisentwicklung darüber entscheidet, ob die Produktion infolge des Quotenausstiegs steigt oder fällt. Bei einer Aufhebung der Quoten wird die EU-Zucker- und Isoglukoseerzeugung überwiegend auf dem EU-Binnenmarkt abgesetzt und führt zu einer Verdrängung von Importen aus Ländern mit präferenziellem Zugang zum EU-Binnenmarkt und zu einem Preisverfall innerhalb der EU-28. Hierdurch sinkt die Zuckerproduktion Drittländern, insbesondere in Afrika. Bei hohen Weltmarktpreisen wechselt die EU-28 ihren Handelsstatus vom Netto-Importeur zum Netto-Exporteur. Der zukünftige Marktanteil von Isoglukose in der EU 28 wird stark durch die Weltmarktpreisverhältnisse beeinflusst. Je niedriger das Weltmarktpreisniveau ist, desto stärker steigen Isoglukoseperzeugung und verbrauch im Zuge des EU Quotenausstiegs.

Iris touching iris : praxis as an alternate paradigm in the writing classroom
Creators: name: Johnson, Lesley
Publisher: name: University of British Columbia
Year: 2010

description: The following paper outlines a response to a perceived need for an alternate paradigm than the one that currently dominates the field of writing pedagogy. The current paradigm, according to the author, operates on assumptions allied with technical rationality, assumptions which are problematic in light of the fundamental values that underpin the very act of writing itself. The paper also explores a possible alternate paradigm, described by the Aristotelian term, praxis, using a creative narrative style in the form of an ongoing dialogue between two sisters over the course of several months. The interaction between the two sisters frames the conceptual inquiry portion found in the five chapters. Through dialogue, the sisters explore issues of value in key aspects of their lives. These emotionally and intellectually charged conversations serve to underscore the author's belief that an alternate paradigm would open new doors in the composition classroom. Engaging in narrative, explains the author, provides a wealth of possible ways to sidestep the predominant action-reaction framework of technical rationality In telling and listening to stories, the author argues that it is possible to realize a different approach to teaching and researching writing.

description: John Desmond Bernal (1901-1970) was one of the most eminent scientists in molecular biology, and also regarded as the founding father of the Science of Science. His book The Social Function of Science laid the theoretical foundations for the discipline. In this article, we summarize four chief characteristics of his ideas in the Science of Science: the socio-historical perspective, theoretical models, qualitative and quantitative approaches, and studies of science planning and policy. China has constantly reformed its scientific and technological system based on research evidence of the Science of Science. Therefore, we analyze the impact of Bernal Science-of-Science thoughts on the development of Science of Science in China, and discuss how they might be usefully taken still further in quantitative studies of science.

description: La participación ciudadana debería dirigir las necesidades de inversión pública de la población, en particular en beneficio de los más pobres. Así se concibe el proceso de presupuesto participativo (PP) implementado en el Perú en el año 2004. Sin embargo, este estudio encuentra que no hay indicios que sugieran una relación robusta entre el PP y la cobertura del agua y calidad del servicio. Ello se explica por las debilidades en el proceso mismo del PP y en el rol de los actores involucrados. Si bien se espera que el PP guíe las demandas de la población, el proceso enfrenta importantes limitaciones que pueden hacerlo ineficiente en la tarea de canalizar los recursos hacia áreas tales como el agua y saneamiento. Además, puede producir resultados inequitativos en tanto los pobres pueden enfrentar mayores costos de participación. Por su parte, las municipalidades tienen limitadas capacidades técnicas y recursos para afrontar los requerimientos de inversión en este sector, y los alcaldes pueden no estar muy interesados en respaldar el PP. Por esto, aunque el PP haya desplazado la inversión del tipo “elefante blanco” (estadios, plazas de toros, etc.) de muchas municipalidades y contribuido a guiarla hacia proyectos más consistentes con las necesidades básicas de la población, necesita ser fortalecido para lograr un papel activo en la provisión de servicios de mejor calidad. Una variable que parece hacer una diferencia, tanto en la cobertura de agua como en la calidad del servicio, es la participación política de las mujeres. En las municipalidades donde las mujeres tienen una mayor participación, el servicio y la cobertura del agua tienden a ser mejores. Esto no debe sorprender, pues se sabe que las mujeres se preocupan mucho más por el acceso al agua potable. Así, en un contexto descentralizado y donde las mujeres participan más, se exige más a los funcionarios de gobierno y a las entidades prestadoras de servicios de agua que mejoren el servicio.

description: We study nonequilibrium effects in current transport through voltage biased tunnel junction with long diffusive superconducting leads at low applied voltage, $eV \ll 2Δ$, and finite temperatures. Due to a small value of the Josephson frequency, the quasiparticle spectrum adiabatically follows the time evolution of the superconducting phase difference, which results in the formation of oscillating bound states in the vicinity of the tunnel junction (Andreev band). The quasiparticles trapped by the Andreev band generate higher even harmonics of the Josephson ac current, and also, in the presence of inelastic scattering, a non-equilibrium dc current, which may considerably exceed the dc quasiparticle current given by the tunnel model. The distribution of travelling quasiparticles also deviates from the equilibrium due to the spectrum oscillations, which results in an additional contribution to the dc current, proportional to $\sqrt{V}$.

description: En los países en desarrollo, la distribución desigual de la calidad de los docentes es un problema que subyace a la distribución desigual de los logros educativos. Sin embargo, poco se sabe sobre cómo el mercado laboral genera este tipo de distribución. Para contribuir a este tipo de conocimiento, este estudio investiga si existe un mercado nacional de docentes en el Perú o, más bien, mercados regionales de menor alcance. En base a modelos multinomiales de elección discreta —estimados con datos de encuestas en las regiones de Loreto y Lambayeque—, se identifican las variables asociadas a la ubicación del primer empleo de los docentes, que incluyen factores geográficos y características de los maestros y del marco institucional. Los resultados revelan que los mercados de docentes son de alcance regional: haber nacido en una provincia determinada aumenta significativamente la probabilidad de conseguir el primer empleo como docente en esa misma provincia. También se encuentra evidencia de que la movilidad geográfica de los docentes es bastante limitada. Estos hallazgos sugieren que las políticas para fortalecer los sistemas de formación docente y reducir las inequidades deben centrarse en el nivel regional.

description: We present a novel deep learning based technique for volumetric ambient occlusion in the context of direct volume rendering. Our proposed Deep Volumetric Ambient Occlusion (DVAO) approach can predict per-voxel ambient occlusion in volumetric data sets, while considering global information provided through the transfer function. The proposed neural network only needs to be executed upon change of this global information, and thus supports real-time volume interaction. Accordingly, we demonstrate DVAOs ability to predict volumetric ambient occlusion, such that it can be applied interactively within direct volume rendering. To achieve the best possible results, we propose and analyze a variety of transfer function representations and injection strategies for deep neural networks. Based on the obtained results we also give recommendations applicable in similar volume learning scenarios. Lastly, we show that DVAO generalizes to a variety of modalities, despite being trained on computed tomography data only.

description: La literatura ha mostrado la importancia de las características individuales en el acceso de los estudiantes a la educación superior. En este documento se utiliza un diseño longitudinal con tres rondas de recolección de datos a fin de examinar los efectos de las características individuales y escolares en la decisión de los estudiantes de postular a educación superior. La muestra incluye estudiantes de instituciones educativas públicas y privadas en Lima, Perú, que se graduaron de la secundaria en el año 2010. Los resultados sugieren que un conjunto de factores individuales y escolares predicen la postulación a educación superior de los jóvenes al año de graduarse de educación secundaria. Aquellos estudiantes que tienen por lo menos un padre con educación superior, tienen casi dos veces más probabilidades de postular a estudios superiores que sus pares cuyos padres poseen solo educación primaria; mientras que los estudiantes de instituciones educativas donde se tomaron más acciones para favorecer su postulación tienen 1,25 veces más probabilidades de postular a educación superior que sus pares de instituciones donde ofrecen menos apoyo institucional, incluso tras controlar por variables a nivel individual y de la escuela. Con respecto al proceso de postulación a educación superior, los alumnos refieren que durante el proceso no solo enfrentan barreras económicas sino también psicológicas, relacionadas principalmente con la falta de información sobre qué y dónde estudiar y un apoyo adecuado por parte de la familia y la escuela. En base a los resultados del estudio se realizan recomendaciones de políticas y programas educativos que favorezcan el acceso de los jóvenes a educación superior.

description: Using the NIRSPEC spectrograph at Keck II, we have obtained infrared echelle spectra covering the range 1.5-1.8 micron for the moderately reddened bulge globular clusters NGC 6342 and NGC 6528, finding [Fe/H]= -0.60 and -0.17 dex, respectively. We measure an average alpha-enhancement of approx +0.33 dex in both clusters, consistent with previous measurements on other metal rich bulge clusters, and favoring the scenario of a rapid bulge formation and chemical enrichment. We also measure very low 12C/13C isotopic ratios (approx 5 in NGC 6342 and approx 8 in NGC 6528), suggesting that extra-mixing mechanisms due to cool bottom processing are at work during evolution along the Red Giant Branch.

description: Mejorar la efectividad de la política fiscal respecto a la redistribución y la reducción de la pobreza es clave para el desarrollo equitativo del Perú. Estudios recientes sugieren que las transferencias públicas y las donaciones son responsables de solo un décimo de la disminución de la pobreza alcanzada en la última década. A través del análisis de la incidencia de impuestos y transferencias en base a datos de encuestas de hogares, este estudio estima los efectos de la política fiscal sobre la pobreza y la desigualdad en nuestro país. Los hallazgos muestran que el alcance de la reducción de la desigualdad generada por la política fiscal del Perú es limitado. Ello se asocia a un gasto social bajo más que a un gasto social ineficiente. La mayoría de los componentes del gasto social son progresivos y el gasto social en general también lo es: las transferencias monetarias directas están bien focalizadas y son efectivas sobre todo en la reducción de la pobreza extrema en áreas rurales. Al mismo tiempo, las transferencias en especie de salud y educación son efectivas en la reducción de la desigualdad. Finalmente, se encuentra que los impuestos directos mitigan ligeramente la desigualdad mientras que los impuestos indirectos son neutrales cuando se incorpora la informalidad a los cálculos. Una implicancia de política es que las transferencias focalizadas son la forma más efectiva de reducir la pobreza a corto plazo. En contraste, la vinculación de beneficios sociales con el empleo formal tiende a excluir a los pobres.

description: We present deep VLA and HST observations of the large-scale jet in 3C 273 matched to 0.3" resolution. The observed spectra show a significant flattening in the infrared-ultraviolet wavelength range. The jet's emission cannot therefore be assumed to arise from a single electron population and requires the presence of an additional emission component. The observed smooth variations of the spectral indices along the jet imply that the physical conditions vary correspondingly smoothly. We determine the maximum particle energy for the optical jet using synchrotron spectral fits. The slow decline of the maximum energy along the jet implies particle reacceleration acting along the entire jet. In addition to the already established global anti-correlation between maximum particle energy and surface brightness, we find a weak positive correlation between small-scale variations in maximum particle energy and surface brightness. The origin of these conflicting global and local correlations is unclear, but they provide tight constraints for reacceleration models.

description: The potential for California sea cucumber (Parastichopus californicus Stimpson) growth and production when in polyculture with suspended Pacific oysters (Crassostrea gigas Thunberg) was investigated. A 12-month field study was undertaken at two oyster culture sites in British Columbia, Canada, to examine the rates of oyster biodeposition and the utilization of this particulate material as a food source by P. californicus. Peaks in sedimentation rates (93.6 g dry wt m⁻² d⁻¹ ) through 8.5 m water depth were observed in April 2004 and July 2004. At the two study sites, fluxes of particulate organic carbon (POC) through 8.5 m in July amounted to 3123 mg C m⁻² d⁻¹ and 4150 mg C m⁻² d⁻¹ and fluxes of total nitrogen (TN) amounted to 441 mg N m⁻² d⁻¹ and 633 mg N m⁻² d⁻¹ . Mean C/N ratios of particulate material in the sediment trap samples ranged between 5.93 and 8.39 and may be classified as being of high nutritional value. Growth and survivorship of sea cucumbers held in experimental trays below the suspended oysters was measured quarterly using total body weight and muscle and skin wet weights. Sea cucumbers grown in trays successfully utilized biodeposits from the cultured oysters and showed a mean weight increase of 42.9 g in approximately 11 months. Growth rates ranged from 0.061 to 0.158 g d⁻¹. Overall growth was affected the absence of visceral organs and the cessation in feeding activity in the November 2004 sampling period. Values for organic content were significantly higher in the foregut (233.0 mg g dry sediment⁻¹) than in the sediment (64.3 mg g dry sediment⁻¹) or in the hindgut (142.8 mg g dry sediment⁻¹) due to digestion and assimilation. Organic material deposited in the trays was utilized by P. californicus with an average efficiency of 48.4%. The successful utilization of the naturally available biodeposits from the cultured oysters does suggest the feasibility of successful culture of this commercially important species in a polyculture system. Feeding activities of P. californicus were examined in laboratory experiments designed to assess the rates of sediment ingestion and organic matter uptake. Sea cucumbers fed natural marine bottom sediment ingested sediment and removed organic matter at an average rate of 9.17 g dry sediment d⁻¹ and 50.3 mg (g dry sediment) ⁻¹ d⁻¹. From these rates, it was determined that this species of sea cucumber could survive and grow on the amount of organic matter deposited

description: We study a higher derivative extension to General Relativity and present a fully nonlinear/non-perturbative treatment to construct initial data and study its dynamical behavior in spherical symmetry when coupled to a massless scalar field. For initial data, we compare the obtained solutions with those from alternative treatments that rely on a perturbative (or iterative) approach. For the future evolution of such data, we implement a recently introduced approach which addresses mathematical pathologies brought in by the higher derivatives. Our solutions demonstrate the presence of unexpected phenomena -when seen from the lense of General Relativity, as well as departures from General Relativity in the quasi-normal mode behavior of the scalar field scattering off the black hole.

description: La división entre empleo formal e informal es una característica notable del mercado laboral peruano. Las políticas implementadas para reducir el tamaño de la informalidad laboral, como la expansión del régimen para las microempresas y pequeñas empresas, no han tenido un efecto significativo. Este estudio indaga sobre los efectos del largo ciclo de expansión del empleo y de los ingresos en la última década. A través de datos de la ENAHO 2001-2010, se identifica de qué manera el desempeño del mercado laboral, las instituciones y las políticas han afectado la segmentación del mercado laboral durante este periodo. Además, se documenta el significado de la dualidad formal/informal en términos de indicadores de calidad del empleo. Los hallazgos muestran que, a pesar de un contexto demográfico exigente, el mercado laboral peruano ha logrado un desempeño positivo gracias a que el crecimiento del empleo ha superado el de la fuerza laboral, lo que ha producido una disminución de las tasas de desempleo y subempleo, así como mejoras en diversos indicadores de calidad del trabajo. Ello ha hecho posible una modesta reducción en el tamaño del sector informal y ha incrementado la movilidad del empleo informal al formal. Sin embargo, la segmentación sigue siendo una característica notable del mercado laboral peruano, debido a que el empleo en las microempresas continúa creciendo, aunque no a la misma velocidad que en las grandes empresas. El acceso a la seguridad social también dista mucho de ser el ideal. Por otro lado, ha habido un rápido crecimiento de los contratos a plazo fijo. Estos resultados sugieren que el dinamismo positivo del mercado laboral es insuficiente para reducir la informalidad en un plazo razonable.

description: General field theory of a fluctuating d-wave superconductor is constructed and proposed as an effective description of superconducting cuprates at low energies. The theory is used to resolve a puzzle posed by recent experiments on superfluid density in severely underdoped YBCO. In particular, the overall temperature dependence of the superfluid density at low dopings is argued to be described well by the strongly anisotropic weakly interacting three-dimensional Bose gas, and thus approximately linear in temperature with an almost doping-independent slope.

description: A puzzle has long existed for the $α$-cluster content in the near-threshold 7.54 MeV state of $^{10}$Be. A new measurement was conducted to measure the cluster-decay partial width of this state, using the reaction $\rm{^9Be}(\rm{^9Be}, \rm{^{10}Be}^{*} \rightarrow α+ \rm{^6He})\rm{^8Be}$ at 45 MeV beam energy. Special measures were taken to reduce the strong near-threshold background. The neutron-decay strength was also obtained based on the three-fold coincident measurement. A cluster-decay branching ratio of $(4.04 \pm 1.26)\times 10^{-4}$ is obtained, resulting in a reasonably large $α$-cluster spectroscopic factor. The present work confirms the formation of the $σ$-bond molecular rotational band headed by the 6.18 MeV state in $^{10}$Be.
