Repulsion Between Inorganic Particles Inserted Within Surfactant Bilayers
We study by synchrotron small-angle x-ray scattering highly aligned lamellar phases of a zwitterionic surfactant, doped with monodisperse and spherical hydrophobic inorganic particles as a function of particle concentration. Analysis of the structure factor of the two-dimensional fluid formed by the particles in the plane of the bilayer gives access to their membrane-mediated interaction, which is repulsive, with a contact value of about 4kBT and

Site directed spin labeling in combination with electron paramagnetic resonance spectroscopy has become a very effective tool for studying the dynamics and structure of biomolecules in their native environment. This work presents the basics of site directed spin labeling and provides our results obtained in spin labeling hemerythrin and hemoglobin using methanethiosulfonate spin label. Best fit magnetic and libration parameters are obtained by simulation

Excess enthalpies, HE, at 298.15 K and atmospheric pressure determined for twelve binary liquid mixtures containing nitromethane or nitroethane + 1-chlorobutane, + 1-chloropentane, + 1-chlorohexane, + 1,2-dichloroethane, + 1,3-dichloropropane, and + 1,4-dichlorobutane by means of a flow 2277-LKB microcalorimeter, are reported on over composition range. The experimental results, along with the literature data on vapour-liquid equilibrium, VLE, excess

La fenomenologia rappresenta una delle principali correnti della filosofia del secolo XX. Nata ai primi del Novecento nel contesto dei vivaci dibattiti sui fondamenti della filosofia e delle scienze, si è presto imposta come protagonista della discussione filosofica per tutto il secolo scorso, mantenendo, fino ai giorni nostri, una costante vitalità e una inesauribile ricchezza di temi e problemi. Il volume offre al lettore una presentazione delle

In this article, we will analyse the emergence and evolution of the problem of corporeality in the early writings of Emmanuel Levinas, especially from 1935 to 1947. In these texts, the ego is constituted through a cohering with the self and to its own body. Alterity breaks this carnal adhesion to the self. But this break has also a dimension essentially related to embodiment: alterity is understood here not only under the paradigm of nudity, as that
