Declinations of prison from past to future
Over the centuries prisons have been and still are the place where people lost their personal freedom. In the past, imprisonment had a strictly punitive character: it was the place where prisoners served their punishment, often in inhuman conditions precisely because guilty. In more recent times, legislators achieved improvements for the condition of inmates, transforming the prison into a place of rehabilitation leading to the reintegration into civil society. Many complexes have lost their original function over time: some have become places of memory of a past that should not be forgotten, others have been converted to new uses compatible with the original structure
Space for cooking in housing architecture
The preparation and cooking of food is part of everyday life from the moment in which man began to cook meat on fire; thus a process has begun that has led the space where these functions are carried out to becoming one of the most significant environments in the house. With the passing of time and changing needs, the kitchen has undergone substantial changes both in terms of its location and importance within the house, and for its furnishings and equipment
Water in Architetture, Architecture of Water
Water is one of the fundamental resources for the survival of humanity and during the centuries in all the world it became integral part of building and garden architecture. For this reason, starting from general considerations of our countries of origin, we wanted to collect in this article some of the most representative examples of water treatment all over the world in three different fields: the outdoor spaces, the indoor spaces and the in-between spaces, both public and private, to mark the role of water in the designing of architectural process in the last 25 years and proposals for the future not so far
Corner Structure of Four-Dimensional General Relativity in the Coframe Formalism
This note describes a local Poisson structure (up to homotopy) associated with corners in four-dimensional gravity in the coframe (Palatini–Cartan) formalism. This is achieved through the use of the BFV formalism. The corner structure contains in particular an Atiyah algebroid that couples the internal symmetries to diffeomorphisms. The relation with BF theory is also described
Study of the isotropic contribution to the analysis of photoelectron diffraction experiments at the ALOISA beamline
The angular distribution of the intensity in photoemission experiments is
affected by electron diffraction patterns and by a smoothly varying ISO
contribution originated by both intrumental details and physical properties of
the samples. The origin of the various contributions to the ISO component has
been identified since many years. Nonetheless in this work we present original
developement of the ED analysis, which arises from the evolution of
instrumental performance, in terms of analyzers positioning and angular
resolution, as well as collimation and size of X-ray beams in third generation
synchrotron sources. The analytical treatement of the instrumental factors is
presented in detail for the end station of the ALOISA beamline (Trieste
Synchrotron), where a wide variety of scattering geometries is available for ED
experiments. We present here the basic formulae and their application to
experimental data taken on the Fe/Cu3Au(001) system in order to highlight the
role of the various parameters included in the distribution function. A
specific model for the surface illumination has been developed as well as the
overlayer thickness and surface roughness have been considered.Comment: RevTex, nine pages with five eps figures; to be published in J.

Architecture, science and exhibit: yesterday and today
Architecture and science have always been interrelated for educational purposes. For this reason the course of Interior Architecture and Exhibit Design at Master of Science in Architecture Construction City of Politecnico di Torino, starting from the knowledge of the role of the Academy and its scientific content, proposed new and current forms of exhibits and communication in respect of the courtly architecture that is called to emphasize with its language the authority and perennial values of the sciences
Local law-of-the-wall in complex topography: a confirmation from wind tunnel experiments
It is well known that in a neutrally-stratified turbulent flow in a deep
constant-stress layer above a flat surface, the variation of the mean velocity
with respect to the distance from the surface obeys the logarithmic law (the
so-called ``law-of-the-wall''). More recently, the same logarithmic law has
been found also in the presence of non flat surfaces. It governs the dynamics
of the mean velocity (i.e. all the smaller scales are averaged out) and
involves renormalized effective parameters. Recent numerical simulations
analyzed by the authors of the present Letter show that a more intrinsic
logarithmic shape actually takes place also at smaller scales. Such a
generalized law-of-the-wall involves effective parameters smoothly depending on
the position along the underlying topography. Here, we present wind tunnel
experimental evidence confirming and corroborating this new-found property. New
results and their physical interpretation are also presented and discussed.Comment: 9 pages, (Latex), 4 figure
