Studio della resistenza alla corrosione di acciai impiegati nell’industria alimentare e delle bevande

2020

In the present study we performed the physico-chemical characterization of passive films grown on different stainless steel grades after long exposure time in hot purified water (HPW). In order to get more insight into dissolution phenomena that can induce rouging on equipment materials typically involved in food and beverage industries, 304L, 316L and a super duplex 2507 SS samples were passivated at the open circuit potential by different immersion times in HPW at 60°C. Photoelectrochemical and Electrochemical Impedance measurements were performed in the attempt to correlate the electronic properties of the passive films (band gap and conductivity type) to their corrosion resistance.

Politica al femminile. Margherita Bontade militante democristiana nella Sicilia dei primi anni della Repubblica

2014

Margherita Bontade è una tra le più singolari figure di donne impegnate in politica nella Sicilia del Secondo Dopoguerra; tra le poche ad aver trovato spazio nella cerchia dei potenti democristiani del tempo, occupati ad opporsi all’avanzata dei partiti del Blocco del Popolo, con la benedizione delle gerarchie della Chiesa Cattolica. Le sue fortune elettorali dipendono, da un lato, al suo stretto legame con la Curia e al rapporto personale con il Cardinale di Palermo Ernesto Ruffini; d’altro lato, all’alleanza politica prima con Bernardo Mattarella e poi con Franco Restivo. La sua fulminante carriera politica che si snoda nell’arco di un ventennio – tra la fine degli anni ’40 e la fine degl…

Transition from self tilt to object tilt during maintained lateral tilt in parabolic flight.

1991

Abstract 19 young healthy subjects were subjected to parabolic rollercoaster flight. A horizontal luminous line was seen by the subjects in a headfixed goggle device. During the hypergravic phases of parabolic flight the luminous line seemed to rotate into and during the hypogravic phase against the direction of static head tilt. Ocular counter rotation and activity of the neck position receptors cannot explain these subjective rotations. We conclude that information from the otolith system, converging with visual information within the brain, dislocated the headfixed visual target line. While the retinal image of the luminous line remains unchanged, loading and unloading the otoliths in pa…

Uno strumento di insegnamento e apprendimento riflessivo nella formazione degli insegnanti al tempo del Covid: lo storytelling digitale

2021

Tra le varie forme narrative, negli ultimi anni si sta diffondendo l’uso del cosiddetto “storytelling digitale”, ovvero uno strumento attraverso il quale lo studente può raccontarsi e ritrovare tutti gli elementi caratterizzanti un’esperienza didattica vissuta. Il contributo si propone l'obiettivo di valutare in termini di soddisfazione e percezione del proprio apprendimento, la ricaduta dell’esperienza narrativa da parte degli studenti universitari che hanno frequentato a distanza nel primo semestre dell’anno accademico 2020-21, il corso di Docimologia previsto al secondo anno (cattedra M-Z) del Corso di Studi in Scienze della Formazione Primaria, attraverso l’impiego dello storytelling di…

The Rotary Aero Engine from 1908 to 1918

2012

The rotary aero engine is a special type of air-cooled radial engine, where the cylinders are arranged like the spokes of a wheel and turn around the crankshaft. The propeller is connected to the cylinders, while the crankshaft is fixed to the frame. The rotary aero engine, developed in 1908, set new standards of power and light weight within the aircraft industry. It was adopted by many pioneer aviators and widely used to set records of endurance, speed and height. Many aero engine manufacturers produced different models and variants of this type of engine, which was extensively used until the end of the First World War. The latest evolution of the rotary engine was the counter-rotary arra…

Achievement Orientations, School Adjustment, and Well-being: A Longitudinal Study

2007

This study set out to identify the kinds of achievement orientations that adolescents show, and to examine the kinds of antecedents and consequences the use of a particular orientation has. The participants were 734 Swedish adolescents (335 boys and 399 girls) who filled in questionnaires measuring their achievement beliefs and behaviors, depressive symptoms, engagement with school, and norm-breaking behavior. By using clustering-by-cases analysis, five achievement orientation groups were identified: optimism, defensive-pessimism, self-handicapping, and learned helplessness, and a group showing average levels of criteria variables. The results showed further that a decrease in depressive sy…

The turbulence of images: On imagery, media and ethnographic discourse

1997

As the anthropological theory of politeness has put it, people have universally two kinds of social want. They wish to be close to others, liked and accepted, but they also want some distance, freedom from imposition and respect of mutual difference. These wants, which one may also call basic human rights, are however often violated, and images play an important role in this. Images are ultimately generated in the human mind and may find verbal as well as written and pictorial representation. Tyler [1978] has proposed a typology of mental images based on criteria of conscious control, completeness, abstraction, media and autonomy. These criteria also prove useful when probing into prototypi…

Depression : The differing Narratives of Couples in Couple Therapy

2014

Introduction When a person becomes depressed, partnership can either be a source of strength, advancing recovery, or a source of further suffering, harming the health of both partners (Cordova & Gee, 2001). Also, depression in one spouse can create feelings of helplessness and hopelessness in both spouses (Cordova & Gee). These are some of the reasons why couple therapy has been used with persons diagnosed with depression and their spouses. Yet, according to Denton and Burwell's (2006) experience, which is similar to our own, the spouses of depressed patients often are not part of the treatment in psychiatric outpatient care, and hence feel unsupported, uninformed, isolated, confused, and f…

Effect of saliva contamination on bracket failure with a self-etching primer: A prospective controlled clinical trial

2010

Introduction The aim of this study was to evaluate in vivo the effect of saliva contamination at different stages of the bonding procedure on the bond failure rate and the adhesive remaining on teeth after debonding brackets bonded with a hydrophilic self-etching primer (Transbond Plus self-etching primer [TSEP], 3M Unitek, Monrovia, Calif). Methods This was a prospective controlled clinical trial. The sample consisted of 46 patients with similar treatment plans and mechanotherapies. Stainless steel brackets (n = 531) were bonded with TSEP. The patients were divided into 2 groups: contamination with saliva before TSEP application and contamination with saliva after TSEP application. In both…
