Una tarde de té en la Casa Eames

En el año 2012 se celebró en la Casa de Charles y Ray Eames una ceremonia del té que congregó a unos pocos invitados. El acto pretendía rememorar otro que había tenido lugar en el mismo espacio 60 años atrás, en el que los Eames habían recibido a distinguidos invitados como Charlie Chaplin o Isamu Noguchi. En ambas ocasiones, la estética del ‘select and arrange’ de los Eames, junto con las intervenciones artísticas de sus invitados, componían una desnuda escenografía, con cierto aire occidentalizado, que servía de base para la celebración de la ceremonia. Estos eventos, así como los elementos e invitados que aquí se reunieron, suponen una pequeña muestra del vínculo de los Eames con el diseño y la arquitectura japoneses y, en concreto, la plasmación de algunos ideales comunes manifestados en su propia e icónica casa californiana, configurándose como capítulos esenciales en la singular vida de este edificio

First order alignment transition in an interfaced active nematic

We investigate experimentally the dynamic phase transition of a two-dimensional active nematic layer interfaced with a passive liquid crystal. Under a temperature ramp that leads to the transition of the passive liquid into a highly anisotropic lamellar smectic-A phase, and in the presence of a magnetic field, the coupled active nematic reorganizes its flow and orientational patterns from the turbulent into a quasi-laminar regime aligned perpendicularly to the field. Remarkably, while the phase transition of the passive fluid is known to be continuous, our observations reveal intermittent dynamics of the order parameter and the coexistence of aligned and turbulent regions in the active nematic, a signature of discontinuous, or first order, phase transitions.Comment: 5 manuscript pages with 5 figures, and 7 SI pages with 4 SI figures and 4 SI video captions.

Novel Defect Structures in Nematic Liquid Crystal Shells

We use double-emulsion drops to experimentally investigate the defect structures of spherical shells of nematic liquid crystals. We uncover a rich scenario of coexisting defect structures dictated by the unavoidable finite thickness of even the thinnest shell and by the thickness variation around the sphere. These structures are characterized by a varying number of disclination lines and pairs of surface point defects on the inner and outer surfaces of the nematic shell. In the limit of very thick shells the defect structure ultimately merges with that of a bulk nematic liquid crystal drop

La terapia interpersonal de la depresión y las psicoterapias en el fin del milenio.

En este trabajo presentamos los fundamentos teóricos y clínicos de la Terapia Interpersonal de la depresión y analizamos los motivos que la han consolidado como una alternativa eficaz y frecuentemente practicada de psicoterapia en los Estados Unidos de América. Exponemos la situación en España y en Europa. Discutimos algunas implicaciones de esto para la práctica de la psicoterapia en los próximos años

Radon (222Rn) outgassing in San Juan volcanic tubes during the Cumbre Vieja eruption 2021, and preliminary values in the newly volcanic tubes.

During the eruption at Cumbre Vieja ridge (La Palma, Canary Islands, 2021) a radon (222Rn) detector (CORENTIUM Pro alpha particles counter) was emplaced inside the Las Palomas lava tube (San Juan eruption, 1949). In addition, a CO2 meter logger was emplaced to determine relationships between the 2021 eruption and radon plus CO2 inner fluxes. There is a geostructural relationship between the 1949 and 2021 eruptions, probably connected by a previous fault, shown the volcanic vents¿ alignment trending NW-SE. In October 2021, the radon and CO2 loggers were moved to the upper part of the lava tube, in the San Juan volcanic vent (Llano del Banco hollow dyke). Once the eruption ended (in early 2022) both loggers were placed in one newly formed lava tube, and data will be collected in February 2023. Preliminary results show daily average radon values ranging between 2 - 9 Bq/m3, although sporadic peaks of about 270 and 650 Bq/m3 were recorded related to volcano-tectonic earthquakes and volcanic intensity. In general, basaltic eruptions of alkaline affinity show low radon values due to the low concentration in the magma body of uranium and related chemical elements (Th, Ra, etc.). Geochemical analysis of emitted lavas shows a U concentration of about 1 to 5 ppm (g/g) and Th 9.5 ppm. Summer values of Rn increased up to 3 KBq/m3, related to the climate conditions instead of volcanic activity

Evolution of Balmer jump selected galaxies in the ALHAMBRA survey

Extragalactic astronomy.-- et al.[Context]: Samples of star-forming galaxies at different redshifts have been traditionally selected via color techniques. The ALHAMBRA survey was designed to perform a uniform cosmic tomography of the Universe, and we here exploit it to trace the evolution of these galaxies. [Aims]: Our objective is to use the homogeneous optical coverage of the ALHAMBRA filter system to select samples of star-forming galaxies at different epochs of the Universe and study their properties. [Methods]: We present a new color-selection technique, based on the models of spectral evolution convolved with the ALHAMBRA bands and the redshifted position of the Balmer jump to select star-forming galaxies in the redshift range 0.5 <z< 1.5. These galaxies are dubbed Balmer-jump Galaxies (BJGs). We applied the iSEDfit Bayesian approach to fit each detailed spectral energy distribution and determined star-formation rate (SFR), stellar mass, age, and absolute magnitudes. The mass of the halos in which these samples reside were found through a clustering analysis. [Results]: Five volume-limited BJG subsamples with different mean redshifts are found to reside in halos of median masses ∼10 M slightly increasing toward z = 0.5. This increment is similar to numerical simulations results, which suggests that we trace the evolution of an evolving population of halos as they grow to reach a mass of ∼10 at z = 0.5. The likely progenitors of our samples at z ∼ 3 are Lyman-break galaxies, which at z ∼ 2 would evolve into star-forming BzK galaxies, and their descendants in the local Universe are galaxies with luminosities of 1-3 L. Hence, this allows us to follow the putative evolution of the SFR, stellar mass, and age of these galaxies. [Conclusions]: From z ∼ 1.0 to z ∼ 0.5, the stellar mass of the volume-limited BJG samples changes almost not at all with redshift, suggesting that major mergers play a minor role in the evolution of these galaxies. The SFR evolution accounts for the small variations of stellar mass, suggesting that star formation and possible minor mergers are the main channels of mass assembly.P.T. and A.M.A. acknowledge support from FONDECYT 3140542 and FONDECYT 3160776, respectively.
