The Neue Nationalgalerie by Mies van der Rohe between Preservation and Minimal Improvement

The NeueNationalgalerie (1968) is considered an icon of the 20th century and part of the legacy of Mies van der Rohe. Almost 50 years after its construction the building showed some physiological decay; however, it has been considered obsolete due to the changing standards of use and comfort of an international art gallery affected also by a growing flux of visitors.The paper investigates the future of such an icon of modern architecture moving from some open issues of the intervention carried out by David Chipperfield started up in 2015 and now in an advanced stage. The refurbishment is pursuing the modernization of the building, but trying to match the historical values with the requirements of climate control and safety. The binomials memories/requirements and authenticity/form are at the base of the investigation. Although the intervention confirms the continuity of original use and it is aimed at keeping the image of the icon, it imposes transformations that belong to very different strategies, sometimes incompatible with the preservation of material meanings and values. The restoration work on modern heritage outlines how new cultural and socio-economic needs confront themselves with respecting/reproducing the appearance of the monument

APPRENDIMENTO, LINGUAGGIO E PROBLEM SOLVING

La prevalenza di studenti dislessici in Italia appare inferiore rispetto a quella dei dislessici di lingua Inglese. All’interno di questo articolo, dopo una breve analisi delle cause e delle caratteristiche della dislessia, si cercherà di confrontare, a livello linguistico, la differenza tra i dislessici di lingua Italiana e quelli di lingua Inglese. Particolare rilevanza verrà data agli aspetti linguistici strutturali della lingua Inglese che sembrerebbero essere gli elementi scatenanti la prevalenza di tale disturbo nei paesi di lingua Inglese

Metaphor and Brain: A Neuropragmatic Overview

This article offers an overview of the different types of metaphor and cognitive abilities that are required in metaphor comprehension. It does so in connection with the general psycholinguistic and prag- matic theories of metaphor, which are examined briefly. Attention is then turned to neuropragmatic functions and the brain in terms of anatomic structure and functioning. Finally, the article suggests some relevant areas for future research

UN DISTURBO DELL'APPRENDIMENTO: LA DISLESSIA NELLA LINGUA ITALIANA E NELLA LINGUA INGLESE

The percentage of dyslexic students in Italy is lower than in the United Kingdom. In this article, after a brief analysis concerning the main dyslexia causes and symptoms, a differen - ce between Italian and English dyslexic will be made on a lin - guistic level. The linguistic aspects of English language will be analysed because they seem to be the main cause of the major prevalence of dyslexia in students speaking English

Privatizations are synonymous with economic efficiency?: Reflection on the argentine case

During the 1990S Argentina implemented a profound process of transferring to private capital of public enterprises and strategic areas that historically had remained under the ownership and management of the national State. These privatizations has as target the promotion of economic efficiency of the companies subject to privatization and, therefore, the overall economy. However, the privatizations were mostly of public services operating in markets are not competitive enough, therefore the degree of economic efficiency is more conditioned by the own competence and regulating that by the ownership private or public of the company.Privatizaciones, estructura del mercado

Classification of hemispheric monthly mean stratospheric potential vorticity fields

International audienceMonthly mean NCEP reanalysis potential vorticity fields at the 650 K isentropic level over the Northern and Southern Hemispheres between 1979 and 1997 were studied using multivariate analysis tools. Principal component analysis in the T-mode was applied to demonstrate the validity of such statistical techniques for the study of stratospheric dynamics and climatology. The method, complementarily applied to both the raw and anomaly fields, was useful in determining and classifying the characteristics of winter and summer PV fields on both hemispheres, in particular, the well-known differences in the behaviour and persistence of the polar vortices. It was possible to identify such features as sudden warming events in the Northern Hemisphere and final warming dates in both hemispheres. The stratospheric impact of other atmospheric processes, such as volcanic eruptions, also identified though the results, must be viewed at this stage as tentative. An interesting change in behaviour around 1990 was detected over both hemispheres

Manometric monitoring of biological denitrification

A simple, automated manometric method is here discussed and applied to perform batch experiments for the stoichiometric and kinetic characterization of biological denitrification. The main strength of the proposed methodology is that it requires simple instrumentation, which is usually available in wastewater treatment plant laboratories, being it used in BOD and in BMP tests. The experimental setup consists of a glass bottle, a mixing and termostated system and a manometric bottle-head which can measure and log the overpressure that is caused by denitrified N2. At first, tests were conducted to determine the repeatability of the method; they were performed under low Food-to-Biomass ratio and with both endogenous and externally dosed carbon sources. Later, experimental procedures were performed to assess (1) the anoxic growth yield, (2) the endogenous anoxic decay rate; (3) the anoxic growth rate on acetate; (4) the fraction of anoxic active biomass in the sludge sample. Sludge samples for all these tests were taken from two WWTPs and 6 to 10 replicates were performed each time. Results indicated that the testing procedures is well repeatable and reliable and resulting estimates were within reported literature values
