La ricerca della paternità deve essere ammessa. La civilistica postunitaria e le riforme del diritto di famiglia. Questioni di diritto transitorio
No full textLa norma del codice civile italiano del 1865 che prevede il divieto di indagini sulla paternità naturale costituisce una profonda innovazione, sia rispetto alla prassi giudiziaria medievale e moderna, sia rispetto alla legislazione preunitaria di primo Ottocento.
La circostanza determina un vasto dibattito dottrinale, con una forte corrente di civilisti impegnati nel chiedere una riforma del codice, ma produce anche una rilevante casistica giurisprudenziale, in relazione soprattutto alla risoluzione di questioni di diritto transitorio. Complessa in specie la situazione dei territori già appartenuti al Lombardo-Veneto e sottoposti in precedenza alla molto diversa disciplina dell’ A. B. G. B. austriac
The power of fiction and its controversies in Azar Nafisi’s portrayals of a new compliant nationality
No full textAccording to Anderson’s positions on nation and nationalism as cultural artifacts, Azar Nafisi’s literary memoirs show a controversial case study, focused on the ambiguities of the exile discourse and of the so-called «imaginative knowledge». Through the lens of a recurring celebration of Western myths of freedom, a series of stereotypes and paradoxes will be examined, in relation to the censorship experienced by the author under the Islamic Republic of Iran. Moreover, Nafisi’s juxtaposition of political and literary perspectives will be shown as an ambivalent narrative strategy, despite her search for a true self without any ideological engagement. In the end, the explored duality between oriented dissertations and pure imaginative recreations will enable to reconsider Nafisi’s memoirs as committed depictions of a Westernized national legacy
Effect of treatment with L-deprenyl on age-dependent microanatomical changes in the rat kidney.
No full textThe influence of aging and of treatment with L-deprenyl on the structure of the kidney was investigated in 24-month-cld male Sprague Dawley rats by microanatomical techniques associated with image analysis. L-Deprenyl was administrated orally for 5 months at a dose not inhibiting monoamine oxidase (MAO) B activity (1.25/mg/kg/day) and at a dose inhibiting MAO B activity (5 mg/kg/day). In 24 month-old-rats the number and the volume of glomeruli was reduced in comparison with 12-month-old rats used as reference adult animals. Vascular changes characterised by increased thickness of the tunica media, decreased size of arterial lumen and increased wall-to-lumen ratio were also noticeable in 24-month-old rats. Moreover, an increased MAO B reactivity was noticeable within glomerular tufts and renal tubules. Treatment with the low dose of L deprenyl did not cause changes in MAO B reactivity, or in the number of glomeruli, but increased glomerular volume and reduced the wall-to-lumen ratio in medium-sized renal artery branches. The dose of 5 mg/kg/day of L-deprenyl significantly decreased MAO B reactivity within both glomerular tufts and tubules, increased the number and the volume of glomeruli and countered-age-related vascular changes. The above results suggest that treatment with L-deprenyl counters to some extent microanatomical changes occurring in the kidney of aged rats. The observation that the dose of the compound inactive on MAO B activity reduces in part age dependent renal microanatomical changes, indicates that the renal protective effect of L-deprenyl is only in part related to MAO B inhibition
Characterisation of the Thermal Damage in a Martensitic Steel Substrate Consequent to Laser Cladding Process
No full textAbstractThe paper deals with the study of the thermal damage of the substrate during the laser cladding process. The laser cladding process is known as a process which causes small thermal damage in the base material situated directly below the deposited powder. However when the laser cladding process is applied to martensitic steels, that have been previously treated in order to obtain well balanced hard and tough structures, the deposition of the heated powder as well as the interaction of the laser beam with the surface can modify the base material properties beneath the cladding layer. As a consequence uncontrolled, different and variable in hardness microstructures are produced. A 1kW fiber laser source transmitted trough a 50μm delivery fiber was employed to deposit a common Co-base powder over a martensitic stainless steel. Different process conditions were tested in order to reproduce different temperature fields in the base material. The temperature field in the substrate was measured making use of micro-thermocouples able to capture the fast heating and cooling thermal cycles during the deposition process. The microstructure analysis of the heat affected zones beneath the cladding layer together with the microhardness measurements allowed the thermal damage in terms of extension and intensity to be characterized and compared with the corresponding thermal cycles
Repeated administrations of (-)-deprenyl increase [3H]MK801 binding in rat brain and antagonize the impairment of passive avoidance conditioning induced by N-methyl-d-aspartate receptor antagonists
No full textRepeated but not single administrations of the MAO type B inhibitor (-)-deprenyl (1 μmol/kg s.c. for 21 consecutive days) antagonized the impairment of passive avoidance retention induced by the N-methyl-d-aspartate (NMDA) receptor antagonists 2-amino-5-phosphonovalerate (APV), ketamine and dizocilpine (MK801), in rats. In well-washed membranes prepared from the hippocampi of rats repeatedly treated with (-)-deprenyl, the [3H]MK801 specific binding was increased. In contrast, repeated MAO B-selective doses of pargyline or (+)-amphetamine, as well as single injections with (-)-deprenyl failed to change [3H]MK801 binding. It is suggested that the effects of repeated (-)-deprenyl administrations upon NMDA receptors and upon the impairment of acquisition of a passive avoidance task induced by NMDA antagonists could be independent of MAO inhibition. © 1994
La necessità come categoria giuridica: un’ipotesi di lavoro per Jacopo Menochio
No full textNella biblioteca trivulziana di Milano si conserva, in un unico voluminoso manoscritto, il trattato De necessitate, eiusque privilegiis et prerogativis di Jacopo Menochio.L’impostazione scelta da Menochio può essere meglio compresa grazie al confronto con altri trattati cinque-seicenteschi che affrontano temi dalla stessa natura trasversale e articolata (la povertà, la malattia e simili).Benchè l’opera sia incompleta, la lettura si rivela di notevole interesse sia nella prima parte, più rifinita e meditata, dedicata all’introduzione teorica sul concetto filosofico-giuridico di necessità, sia in quella, assai più confusa e frammentaria, in cui l’autore progettava di analizzare in modo analitico i numerosi privilegia, che nell’ambito del diritto si collegano alle diverse concezioni e situazioni di necessità. Proprio il carattere disorganico del codice lo rende anzi di particolare rilievo: oltre a dare un saggio del sapere giuridico del professore pavese, alle prese con un concetto dalle molteplici sfaccettature teorico-pratiche, il testo offre una interessante visione del metodo di lavoro con il quale va costruendosi un trattato su un tema così complesso, e ci mostra il modo in cui un illustre giurista dell’età del tardo diritto comune padroneggia l’immensa mole delle fonti e delle autorità di riferimento per giungere alla soluzione di ogni possibile caso concreto.In the Trivulziana Library in Milan, the treatise De necessitate, eiusque privilegiis et prerogativis, by Jacopo Menochio, is preserved in a single voluminous manuscript.The method chosen by Menochio can be better understood through comparison with other sixteenth-seventeenth century treatises that deal with themes of the same transversal and complex nature (poverty, illness and the like).Although the work is incomplete, the reading reveals itself of considerable interest both in the first part, more refined and meditated, dedicated to the theoretical introduction on the philosophical-juridical concept of necessity, as in the much more confused and fragmentary part, in which the author planned to analytically analyze the numerous privilegia, which in the field of law are connected to the different conceptions and situations of necessity. The very disorganized nature of the code gives it a particularly significant: in addition to providing a sample of the juridic knowledge of the professor from Pavia, dealing with a concept of multiple theoretical and practical facets, the text offers an interesting vision of the working method with which a treatise on such a complex theme is being constructed, and shows us the way in which an illustrious jurist of the late ius commune era masters the immense mass of sources and reference authorities to reach the solution of every possible concrete case
