From the Life Phenomenology to the Criticism of Work Objectiveness (M. Henry, La Barbarie)

This article aims to analyze Michel Henry’s denunciation of the dehumanization of work in modern culture. The pretension to extend the instrumental scientific vision to all dimensions of human life determines, among other consequences, the loss of the genuine meaning of work as a display, and manifestation of subjective life. The study is part of the phenomenology of transcendental subjectivity that Henry proposes, whose intellectual keys are the understanding of life as “auto-affection” and the theory of the body as the pathos of living flesh, the “I” as “subjective body”. The notion of body-appropriation and its implications regarding work are examined, as exposed in Barbarism (chapters 1 and 3) to guarantee the unity of body-land and convert work as an expression of the subjective body through the objective body, avoiding any risk of rupture between them. The reflection leads to the conclusion that although Henry provides a vision of work that responds to life in its phenomenological reality, it is worth questioning whether confining the individual to his own subjectivity guarantees the ability of the work as a means of personal fulfillment. The unity and complexity of the human being demand a deep understanding of his personal being and the permanent search for a unifying principle so that work can be appreciated as an expression of a being that not only works through his body, but is himself that body that lives, acts, and works. Keywords: Work, life phenomenology, subjectivity, immanence, self-affection, living body Resumen El propósito del presente ensayo es analizar la denuncia de Michel Henry a la deshumanización del trabajo en la cultura moderna. La pretensión de extender la visión científica instrumental a todas las dimensiones humanas determina, entre otras consecuencias, la pérdida del sentido genuino del trabajo como despliegue y manifestación de la vida subjetiva. El estudio se enmarca en la fenomenología de la subjetividad trascendental que Henry propone, cuyas claves intelectuales son la comprensión de la vida como «autoafección» y la teoría de la corporalidad encarnada, el «yo» como «cuerpo subjetivo». Se examina la noción de cuerpoapropiación y sus implicaciones con respecto al trabajo, tal como se exponen en La Barbarie (caps. 1 y 3) para garantizar la unidad entre el cuerpo y la tierra y convertir el trabajo en medio de exteriorización del cuerpo subjetivo a través del cuerpo objetivo, evitando todo riesgo de ruptura entre ellos. La reflexión conduce a la conclusión de que si bien Henry aporta elementos para reconducir el trabajo hacia los intereses de la vida, cabe cuestionarse si confinar al individuo a su propia subjetividad garantiza la visión del trabajo como medio de realización personal. La unidad y la complejidad del ser humano demandan una comprensión profunda de su ser personal y la búsqueda permanente de un principio unificador de manera queel trabajo se pueda apreciar como expresión de un ser que no solamente trabaja a través de su cuerpo, sino que es él mismo ese cuerpo que vive, actúa y trabaja.

FGF2, but not EGF, Induces multiciliated ependymal cells to dedifferentiate and adopt radial glial features in vitro

Multiciliated ependymal cells form an epithelium lining most of the ventricular cavities of vertebrates brain. Although considered postmitotic and completely differentiated, ependymal cells maintain some phenotypic characteristics of neural stem cells. Thereby, under specific conditions they behave as neural stem cells, developing radial glia characteristics, and undergoing asymmetric division. Our group is searching for factors that promote dedifferentiation of ependymal cells in vitro. We developed a simple method to obtain pure cultures of non-adherent multiciliated ependymal cells from adult rats. These cultures were used to investigate the effect of FGF2 on the differentiation state and the aggregation of ependymal cells. Thus, FGF2 treated ependymal cells lose cilia and hence mobility, and after 7 days they aggregate to form irregular spheres (diameter ≥ 20-30 μm). Such changes were not observed when EFG was used instead of FGF2. To assess the specificity of FGF2 action on cell aggregation, the FGF receptor inhibitor PD166866 and an anti-FGF2 neutralizing antibody were used. In both conditions the aggregative effect of FGF2 was abolished. No cell proliferation was observed during sphere formation, at least in such experimental conditions. Spheres were analyzed by immunocytochemistry using radial glia markers. They were positive for GFAP, vimentin, BLBP and GLAST. These data suggest that FGF2 promotes the identity loss in multiciliated ependymal cells in vitro, which are transformed into cells with radial glia features.Universidad de Málaga.

Experiencias de cátedra en las clases de física de primer curso de Escuelas Técnicas

We have performed a set of lecture room experiences in a Physics course at the Escuela Universitaria de Informática, of the Universidad Politécnica de Valencia; we have studied the effects produced on the students. This paper shows that we can prepare and perform this method easily, and also its low cost. On the other hand, the general assessment of the students is positive, and it is particularly helpful to improve the motivation and the understanding of the concepts

First results from the INDRA-FAZIA apparatus on isospin diffusion in 58,64 Ni+58,64 Ni systems at Fermi energies

An investigation of the isospin equilibration process in the reactions 58;64Ni+58;64Ni at two bombarding energies in the Fermi regime (32 MeV/nucleon and 52 MeV/nucleon) is presented. Data have been acquired during the first experimental campaign of the coupled INDRA-FAZIA apparatus in GANIL. Selecting from peripheral to semi-central collisions, both the neutron content of the quasiprojectile residue and that of the light ejectiles coming from the quasiprojectile evaporation have been used as probes of the dynamical process of isospin diffusion between projectile and target for the asymmetric systems. The isospin transport ratio technique has been employed. The relaxation of the initial isospin imbalance with increasing centrality has been clearly evidenced. The isospin equilibration appears stronger for the reactions at 32 MeV/nucleon, as expected due to the longer projectile-target interaction time than at 52 MeV/nucleon. Coherent indications of isospin equilibration come from the quasiprojectile residue characteristics and from particles ascribed to the quasiprojectile decay.This work was partially supported by the National Research Foundation of Korea (NRF; Grant No. 2018R1A5A1025563) and by the Spanish Ministerio de Econom a y Empresa (PGC2018-096994-B-C22).

Nuclear symmetry energy at work in heavy ion reactions: new results from the INDRA-FAZIA apparatus

The recently coupled INDRA-FAZIA apparatus offers unique opportunities to investigate heavy ion collisions at Fermi energies by combining the optimal identification capabilities of FAZIA and the large angular coverage of INDRA. We present a selection of the results of the analysis of the first experimental campaign performed with INDRA-FAZIA, in which the four reactions Ni-58,Ni-64+Ni-58,Ni-64 have been studied at two different beam energies (32 and 52 MeV/nucleon) in the intermediate energy regime. The present work is focused on the isospin diffusion effects in semiperipheral and peripheral collisions. A stronger isospin equilibration is found at 32 MeV/nucleon than at 52 MeV/nucleon, as expected due to a shorter projectile-target interaction time in the latter cas

This phenomenon has significant relevance considering the remarkable achievements of the shell model and the SDPF-U interaction in the region which is able to predict the fading of the N = 28 shell gap in neutron-rich 44S. Recent measurements narrowed down this discrepancy to an overestimation of the proton amplitude to the quadrupole transition matrix element. The current work aims to propose a different perspective on the puzzle, by studying a direct proton-transfer reaction on 46Ar as a means to directly probe the proton wavefunction of the ground state this isotope. By measuring the amount of l = 0 transfer to the ground state (1/2+) of 47K with respect to the l = 2 to the first excited state (3/2+), we aim to gain insight into the ground state proton wavefunction of 46Ar. We will present a brief description of the experiment performed at the SPIRAL1 facility in GANIL (France). The experimental apparatus allowed a full reconstruction of the two-body reaction thanks to the combination of AGATA, VAMOS, MUGAST, CATS2, and HECTO

Temporal analysis of natural radionuclides deposition at Málaga(2005-2016)

Atmospheric deposition of radionuclides has been investigated in many studies from the aspects of both radiation protection and geochemistry. The present study, carried out in the city of Málaga, in the southeast of Spain, focuses on the assessment of the bulk depositional fluxes of three natural radionuclides: 7Be (cosmogenic origin), and 210Pb and 40K (crustal origin). These three radionuclides are useful markers of particles arising from their respective sources. To obtain fundamental information of atmospheric transportation, sedimentation and geological process of particulate matter, a long-term monitoring of atmospheric deposition has been carried out in Málaga from January 2005-December 2016. Samples of bulk deposition were collected on a monthly basis on a stainless steel tray from January 2005 to December 2016. Afterwards, a volume of 6 L of the bulk deposition was reduced via evaporation to 1 L approximately and transferred to a Marinelli geometry container for gamma counting. Additionally, aerosols samples were collected weekly in cellulose membrane filters of 0.8μm pore size and 47mm diameter with an air sampler lodged in an all-weather sampling station, situated on the roof near the bulk rain collector. Gamma counting of the aerosols and bulk deposition samples was performed using an intrinsic germanium coaxial detector, Re-Ge-type (CANBERRA). This study describes the results and then discusses characteristics of atmospheric deposition of mentioned radionuclides with respect to seasonal variations and dependency on controlling factors. The depositional fluxes of all radionuclides showed a clear seasonal trend with summer minimum and high values in wintertime
