Antonio Berni (1905, Rosario-1981, Buenos Aires)
No full textJuanito, Juanito Laguna, pues tiene nombre y apellido, es un personaje creado por Antonio Berni en 1961. Junto con Ramona Montiel, otro de los personajes de Berni, son tremendamente conocidos en el arte argentino y sudamericano desde su invención hace más de sesenta años. La creación de estos personajes, y en particular la de Juanito, surgió de una reflexión que el artista comenzó a hacer en sus recorridos por periferias, villas miseria y arrabales. Dentro del repertorio de obras asociadas a Juanito Laguna, «Juanito dormido» (1978, oleo, madera, latas, tela, yute, clavos, papel, papel maché y juguete de plástico sobre madera terciada, 156.5 × 111 cm) es una obra más bien tardÃa. Cuatro años antes, en 1974, Berni hizo una obra relativamente similar, en la que Juanito se encuentra inclinado hacia la derecha, como haciendo un efecto de espejo con respecto a la versión de 1978. Tanto la pose dormida de Juanito de 1974 como la de 1978, recuerdan a la personificación de la melancolÃa, famosamente grabada por Alberto Durero en 1514 y consolidada desde ese momento como un motivo iconográfico del arte y la cultura occidental

A 3D-CFD methodology to investigate boundary layers and assess the applicability of wall functions in actual industrial problems: A focus on in-cylinder simulations
No full textIn the industrial practice, 3D-CFD in-cylinder simulations still largely rely on RANS turbulence models and high-Reynolds wall treatments, i.e. based on wall functions. However, the use of the latter represents a potential source of error, leading to poor estimations of shear stress and heat flux at the wall. In fact, universal laws of the wall can be claimed only under very restricted conditions, which are hardly (to say never) met in industrial applications. As a result, typical dimensionless profiles of velocity and temperature on the combustion chamber walls are far from standard wall functions. In the present paper, a methodology to investigate the presence of dimensionless profiles comparable to universal wall laws in boundary layers of actual industrial problems is presented. In particular, attention is focused on 3D-CFD in-cylinder simulations. While the existing literature deals with DNS or hybrid URANS/LES approaches applied to simplified geometries and low revving speed conditions (for computational cost reasons), in the present paper a RANS k-ε turbulence model with a low-Reynolds wall treatment is adopted. In addition, an alternative strategy to extract velocity and temperature dimensionless profiles from the computed fields is proposed. The methodology is preliminary tested on a 2D plane channel (where the existence of wall functions is a priori acknowledged), at both quasi-isothermal and highly non-isothermal conditions. Afterwards, it is applied to the well-known “GM Pancake” engine test case, showing that both u+ and T+ calculated on the combustion chamber walls remarkably differ from analytical standard wall functions. Finally, in order to demonstrate the importance of dimensionless profiles to properly predict heat transfer, two different high-Reynolds simulations of the “GM Pancake” engine are proposed, one with standard wall functions and one with u+ and T+ profiles provided by the low-Reynolds analysis. While the former underestimates heat fluxes, the latter provides results in good agreement with the experiments

Bisphenol S, a Bisphenol A alternative, impairs swine ovarian and adipose cell functions
No full textThe high-volume-produced plastic monomer Bisphenol A (BPA) has been in the spotlight in the last years because of its endocrine disruptor behaviour, leading to disclose the association between the widespread human and wildlife exposure to BPA with reproductive, metabolic and developmental disorders and hormone-dependent cancer onset. These evidences caused restrictions and prohibitions of BPA industrial uses prompting investigations about harmless alternative compounds. Above all, several countries have substituted the parental analogue with Bisphenol S (BPS) in baby care product manufacturing, even if its structural homology to BPA suggests similar endocrine disruptor properties not yet completely ruled out.
In light of this consideration, the aim of this in vitro study was to investigate the effect of BPS exposure (0.1-1-10 μM for 48 h) on granulosa cells which are considered the prime ovarian targets of BPA as a “reproductive toxicant”. Our data document that BPS inhibited E2 production, cell proliferation and scavenging non enzymatic activity (P < 0.05) while significantly (P < 0.05) stimulated cell viability, superoxide (O2-) and nitric oxide (NO) production in cultured swine granulosa cells, a previously validated endocrine cell model for BPA.
Evidence also exists that BPA and its analogues, as environmental lipophilic pollutants, are involved in the disruption of adipose tissue endocrine function, resulting in metabolic effects and thus in potential reproductive disorders.
On this basis, our second purpose was the assessment of BPS effects on mesenchymal stromal cells isolated from porcine adipose tissue, taking into account mesenchymal stromal cells viability and adipogenic differentiation, a process actually demonstrated to be largely affected by endocrine disruptors. Our results show that BPS decreased (P < 0.001) cell viability of proliferating adipose stromal cells.
Taken as a whole, our data demonstrate an effective BPS endocrine disruptor activity at μM concentrations, suggesting that further studies are needed before its use in industrial application as an alternative to BPA
Causes of accidents in pediatric patients: what has changed through ages
No full textAIM:
Accidents are the main cause of death and disability in children and adolescents aged 1-15 years and cause more than one sixth of all infant admissions to hospital. In Italy, about 400 children and adolescents are involved in domestic accidents and more than 200 in road accidents. The aim of the study was to determine the number and type of accidents involving children and adolescents in the area of Siena and to compare present results with those obtained 20 years ago in order to assess the effectiveness of preventive measures evolving in the period.
METHODS:
Two groups of patients were admitted to the hospital of Siena for accidents between 1980-1985 and 2000-2006; age, gender, type of accident, frequency distribution in the study period and age of highest frequency of accidents were analysed.
RESULTS:
The most frequent cause of admission to hospital in the earlier period was limb trauma with and without fracture, whereas in the later period it was head injury without fracture followed by limb trauma with and without fracture, and fracture of the skull, spine and trunk in boys and girls. Some variation in the course of the years was observed in both study period, however a constant, gradual reduction in admissions is evident.
CONCLUSION:
Comparison of these data with those collected 20 years earlier revealed a general reduction in the number of hospital admissions. This encouraging result suggests that what has been done so far is effective and should be continued, and that it is also worthwhile taking measures to further reduce the toll of accidents
