Clausola che vieta la sublocazione (art. 1594 c.c.)
No full textIl presente lavoro prende in esame la clausola con la quale i contraenti del contratto di locazione vietano la facoltà, del conduttore, di sublocare il bene.
Tale clausola non si presenta priva di insidie, soprattutto per le conseguen-ze che derivano dalla violazione del divieto in essa contenuta. Non sempre, infatti, è agevole stabilire il momento in cui si verifica la violazione del di-vieto di sublocare.
Per tali ragioni, verrà posto l’accento sul contenuto che tale divieto può as-sumere e il suo atteggiarsi, ponendo luce sia sulla disciplina codicistica, che su quella speciale
L'identità senza parola. Origine e sviluppo del linguaggio
No full text«Parlare non è necessario», così Tullio De Mau- ro, maestro di linguistica, apriva un suo fortu- nato libro. Eppure, il suono della voce rompe il silenzio della nascita e il suono delle parole ac- compagna la nostra vita fin dal suo inizio. Eventi che suscitano da sempre interrogativi di grande fascino per gli esseri umani: come nasce il pensie- ro? Perché parliamo e scriviamo? Quale discipli- na deve dare risposte a queste domande? Secondo Noam Chomsky, il più noto linguista del Novecento, «non si può parlare di ‘rapporti’ tra la linguistica e la psicologia, perché la lingui- stica fa parte della psicologia, non posso conce- pirla in altro modo. [...] Nessuna disciplina si può occupare dell’utilizzazione o dell’acquisi- zione di un sapere, senza prendere in considera- zione la natura di questo sapere». Ciononostan- te, lo studio dell’origine del linguaggio umano è stato a lungo appannaggio esclusivo della psi- cologia dello sviluppo e della paleoantropologia, mentre i linguisti si sono occupati solo di come funzionano le lingue e si apprendono da adulti. Questo libro vuole proporre, alla luce delle sco- perte della teoria della nascita dello psichiatra Massimo Fagioli, una nuova possibile visione sull’origine del linguaggio e del pensiero, a parti- re dalla biologia umana. Un percorso naturale di acquisizione della lingua materna e poi della li- nea e della scrittura, che tiene conto anche della storia della nostra evoluzione di Homo sapiens
2-sequent calculus: intuitionism and natural deduction
No full textThis approach to studying the minimal intuitionistic modal logic is based on a generalization of Gentzen's original sequent calculus introduced and developed by the author in a previous paper [see Ann. Pure Appl. Logic 58 (1992), no. 3, 229--246; MR1191942 (93k:03056)]. The complete proof-theoretic treatment of the calculus is presented, including the cut elimination theorem with some of its consequences. The author considers the corresponding 2-natural deduction system, followed by the normalization theorem, and analyzes its relationship with the 2-sequent calculus. Such an approach to the proof-theoretic analysis of logical systems seems to be very natural, fruitful and applicable to a wide class of logics

Frequency of musculoskeletal symptoms in diagnostic medical sonographers. Results of a pilot survey
No full textINTRODUCTION: We report the results of a pilot survey in diagnostic medical sonographers. Aim of the study was to evaluate the frequency of musculoskeletal disorders in sonologists and the relationship of these symptoms to ergonomic factors.
MATERIALS AND METHODS: 340 sonographers (258 male, 82 female doctors; mean age 41.5 +/- 7.2 years) were given a questionnaire to fill out. The questionnaire asked questions about the sonologist's age, gender, technique of ultrasound procedure, physical activity, and work-related musculoskeletal complaints. Two symptom lists regarded carpal tunnel syndrome (CTS) symptoms (8 items) and other work-related musculoskeletal symptoms (13 items). The categorized response variables "have now" or "in the past" were provided. The symptoms experienced were categorized into three levels as no symptoms, few symptoms (1-4 symptoms), and many symptoms (> 5 symptoms).
RESULTS: One third of the respondents reported having at least one or more work-related symptoms in the upper extremities. The most frequent symptoms were tingling (17.6%), numbness or finger pain (13.5%). Carpal tunnel syndrome had been diagnosed in 5 cases (1.5%). More than 60% of all respondents have experienced one or more musculoskeletal symptoms in the cervical or lumbar spine. The commonest symptom was neck and low back pain (67%). The pain was generally intermittent and occurred at the end of the workday. Motion impairment in the neck and/or back was present in 23.5% of cases. Twenty-five percent of respondents had received treatments for their symptoms and 10% reported having stopped work because of their symptoms. Data analysis showed that muscular efforts such as gripping the transducer, applying sustained pressure, and scanning with a correlated flexed or hyperextended wrist were significantly correlated with increasing severity of symptoms in the hand, wrist, and forearm area. On the other hand, low back pain appeared to be negatively correlated with correct position of the body.
CONCLUSIONS: Several physical risk factors (e.g., repetitive work and force exertion, twisting of the body and poorly-adjustable chairs) have been identified for work-related upper extremity and spine disorders. Ergonomic redesign of the workstation configuration as well as allowing sufficient recovery time to body and arm muscles appear to be the main goals to achieve prevention of musculoskeletal disorders in sonographers
D-Tagatose Feeding Reduces the Risk of Sugar-Induced Exacerbation of Myocardial I/R Injury When Compared to Its Isomer Fructose
No full textIt is known that fructose may contribute to myocardial vulnerability to ischemia/reperfusion (I/R) injury. D-tagatose is a fructose isomer with less caloric value and used as low-calorie sweetener. Here we compared the metabolic impact of fructose or D-tagatose enriched diets on potential exacerbation of myocardial I/R injury. Wistar rats were randomizedly allocated in the experimental groups and fed with one of the following diets: control (CTRL), 30% fructose-enriched (FRU 30%) or 30% D-tagatose-enriched (TAG 30%). After 24 weeks of dietary manipulation, rats underwent myocardial injury caused by 30 min ligature of the left anterior descending (LAD) coronary artery followed by 24 h′ reperfusion. Fructose consumption resulted in body weight increase (49%) as well as altered glucose, insulin and lipid profiles. These effects were associated with increased I/R-induced myocardial damage, oxidative stress (36.5%) and inflammation marker expression. TAG 30%-fed rats showed lower oxidative stress (21%) and inflammation in comparison with FRU-fed rats. Besides, TAG diet significantly reduced plasmatic inflammatory cytokines and GDF8 expression (50%), while increased myocardial endothelial nitric oxide synthase (eNOS) expression (59%). Overall, we demonstrated that D-tagatose represents an interesting sugar alternative when compared to its isomer fructose with reduced deleterious impact not only on the metabolic profile but also on the related heart susceptibility to I/R injury. © Copyright © 2021 Durante, Sgambellone, Lucarini, Failli, Laurino, Collotta, Provensi, Masini and Collino
Il "demonismo della forma" e il "trascendimento nel nulla". Ferruccio Masini legge Gottfried Benn
No full textIl saggio è suddiviso in una premessa in cui si inquadra il nichilismo di Gottfried Benn, in un secondo paragrafo in cui si analizza la ragione dell'interesse prioritario di Ferruccio Masini per una raccolta tarda di poesie di Gottfried Benn, Aprèslude (1955) - pubblicata in traduzione italiana dal germanista nel 1963 - che si collega con i capisaldi del prontuario dell'artista maturo che Benn esplicita in "Altern als Problem für Künstler" (1954); poi, un successivo paragrafo enuncia il significato del misticismo estetico di Benn nell'ottica di Masini, mostrando l'insistenza del germanista sul concetto di "prospettiva geometrica-astratta" della lirica benniana. Successivamente, negli ultimi due paragrafi, si chiude il cerchio dell'impegno di Masini rivolto all'autore espressionista, giacché a otto anni dalla traduzione e cura di Aprèslude pubblica un'edizione tradotta e commentata della famosa raccolta di liriche del primo periodo benniano, intitolata Morgue (1912). Nelle riflessioni di Benn distillate da Masinil a carica distruttiva della forma e il pensiero sulla violenza si mostrano indipendenti dal conflitto tra individuo e società. In un paragrafo conclusivo è possibile constatare l'interesse di Masini per il nichilismo dello scrittore romantico Jean Paul, alle cui spalle si definisce, come del resto per Benn, il pensiero maturato da Masini sul rapporto tra Dio e uomo attraverso la filosofia di Nietzsche.The essay ist divided into an introduction concerning Gottfried Benn's nihilism, into a second paragraph, in which is analysed the reason of Ferruccio Masini's priority interest for a late collection of poems of Gottfried Benn, Aprèlude (1955) - published in italian translation by the germanist 1963, - placed here in connection with the main points of the mature artist spelt out in the essay "Altern als Problem für Künstler" (1954); furthermore, into a following paragraph which concerns Benn's aesthetic mysticism, read using the interpretation of Ferruccio Masini and showing his insistence on the concept of "geometric-abstract perspective" in Benn's lyric poetry. In the last two paragraphs the circle of the argumentation is closed with some considerations concerning the translated and commented edition of the famous collection of Benn's early poems "Morgue" (1912). In Benn's reflections explicated by Masini the destructive power of the form and the meditation on violence are showed as indipendent from the conflict between the individual and the society. In a last paragraph it is possible to ascertain Masini's interest in the nihilism of the romantic german author Jean Paul, to whose horizont is defined Masini's thought developed on the relationship between god and man by means of Nietzsche's philosophy
