La fruizione artistica: alcuni sviluppi tra psicofisiologia, psicoanalisi e neuroestetica

La tesi proposta in questo testo è la seguente: sia nell’artista come nell’osservatore la mente e il corpo sono in sintonia tra di loro e collaborano alla realizzazione dell’opera. Dopo un breve accenno al funzionamento del cervello umano, l’autore fa prima riferimento alla psicofisiologia, nell’interpretazione di Vezio Ruggeri e poi al modello psicoanalitico di Graziella Magherini. "The artistic fruition: some developments in psychophysiology, psychoanalysis and neuroesthetics". The thesis proposed in this text is as follows: both in the artist and in the observer the mind and the body are in harmony with each other and collaborate to the realization of the work. After briefly mentioning how the human brain works, the author refers first to as Vezio Ruggeri interprets Psychophysiology and then to the psychoanalytic model of Graziella Magherini

Presentazione

Questo ricchissimo volume di Paola Ruggeri, inserito nella prestigiosa serie del Dipartimento di Storia e del Centro di studi interdisciplinari sulle province romane dell'Università di Sassari, costituisce un apporto di grande valore agli studi romani in Africa e in Sardegna, nel solco della tradizione storica degli Atenei Sardi incardinata nel rapporto con il Mediterraneo

A General Correlation of Temperature Profiles Downstream of a Heated-Air Jet Directed Perpendicularly to an Air Stream

An experimental investigation was conducted to determine the temperature profile downstream of a heated-air jet directed perpendicularly to an air stream. The profiles were determined at several positions downstream of the jet as functions of jet density, jet velocity, freestream density, free-stream velocity, jet temperature, and orifice flow coefficient. A method is presented which yields a good approximation of the temperature profile in terms of dimensionless parameters of the flow and geometric conditions

Ultrarelativistic limit of a Rarefied Gas with Internal Structure

The aim of this letter is to check the ultra-relativistic limit of a recent model proposed by Pennisi and Ruggeri [Ann. Phys. 377, 414 (2017)] for a relativistic gas with internal structure. Considering an Eulerian fluid we prove that there exists a critical value of the degree of freedom such that for smaller values of this quantity the ultra relativistic limit of the energy of a gas with structure is the same as the Synge energy for monatomic gases, while for larger degrees of freedom the energy increases with the degree of freedom itself. The limiting equations are accompanied with the explicit expression of the characteristic velocities of the hyperbolic system.Comment: 4 pages, 2 figure

Pre-implantation mouse embryos cultured In vitro under different oxygen concentrations show altered ultrastructures

Abstract Assisted Reproductive Technologies routinely utilize different culture media and oxygen (O2) concentrations to culture human embryos. Overall, embryos cultured under physiological O2 tension (5%) have improved development compared to embryos cultured under atmospheric O2 conditions (20%). The mechanisms responsible for this remain unclear. This study aimed to evaluate the effect of physiologic (5%) or atmospheric O2 (20%) tension on the microscopic ultrastructure of pre-implantation mouse embryos using Transmission Electron Microscopy (TEM). Embryos flushed out of the uterus after natural mating were used as the control. For use as the control, 2-cells, 4-cells, morulae, and blastocysts were flushed out of the uterus after natural fertilization. In vitro fertilization (IVF) was performed using potassium simplex optimized medium (KSOM) under different O2 tensions (5% and 20%) until the blastocyst stage. After collection, embryos were subjected to the standard preparative for light microscopy (LM) and TEM. We found that culture in vitro under 5% and 20% O2 results in an increase of vacuolated shaped mitochondria, cytoplasmic vacuolization and presence of multi-vesicular bodies at every embryonic stage. In addition, blastocysts generated by IVF under 5% and 20% O2 showed a lower content of heterochromatin, an interruption of the trophectodermal and inner cell mass cell membranes, an increased density of residual bodies, and high levels of glycogen granules in the cytoplasm. In conclusion, this study suggests that in vitro culture, particularly under atmospheric O2 tension, causes stage-specific changes in preimplantation embryo ultrastructure. In addition, atmospheric (20%) O2 is associated with increased alterations in embryonic ultrastructure; these changes may explain the reduced embryonic development of embryos cultured with 20% O2
