MadeinMath. A Math exhibition out of many threads
No full textWe describe some motivations lurking behind the making of a Math exhibition. In particular, we refer to MadeInMath and its two set-ups in Triennale di Milano and Museo della Scienza in Trento (MUSE), where the life and works of Italian mathematicians played an important role, like Guido Castelnuovo, Federigo Enriques and Vito Volterra
Vito Volterra
No full textVito Volterra (1860-1940) was one of the most famous representatives of Italian science in his day. Angelo Guerragio and Giovanni Paolini analyze Volterra’s most important contributions to mathematics and their applications, as well as his outstanding organizational achievements in scientific policy. Volterra was one of the founding fathers of functional analysis and the author of fundamental contributions in the field of integral equations, elasticity theory and population dynamics (Lotka-Volterra model). He delivered keynote lectures on the occasion of the International Congresses of Mathematicians held in Paris (1900), Rome (1908), Strasbourg (1920) and Bologna (1928). He became involved in the scientific development in united Italy and was appointed senator of the kingdom in 1905. One of his numerous non-mathematical activities was founding the National Research Council (Consiglio Nazionale delle Ricerche, CNR). During the First World War he was active in military research. After the war he took a clear stand against fascism, which was the starting point for his exclusion. In 1926 he resigned as president of the world famous Accademia Nazionale dei Lincei and was later on excluded from the academy. In 1931 he was one of the few university lecturers who denied to swear an oath of allegiance to the fascistic regime. In 1938 he suffered from the impact of the racial laws. The authors draw a comprehensive picture of Vito Volterra, both as a great mathematician and an organizer of science
Graft Detachment After Descemet's Stripping Automated Endothelial Keratoplasty in Bullous Keratopathy and Fuchs Dystrophy
No full textDescemet’s stripping automated endothelial keratoplasty (DSAEK) is a surgical technique for corneal transplantation in case of corneal decompensation. One of the main complications is graft detachment (GD) recoverable with Air Re-bubbling (ARB). The aim of this retrospective, interventional case series was to identify factors related to this complication in eyes operated for bullous keratopathy (BK) and Fuchs dystrophy (FD). We considered one-hundred patients who underwent DSAEK for BK or FD between January 2016 and October 2017 at Department of Ophthalmology, Policlinico Universitario of Bari, Italy. Studied parameters included physiological and pathological anamnesis of both donors and recipients and properties of donor lenticules and of the recipient corneas. Data was analyzed using One-way ANOVA with Tukey post hoc test and Chi-square test with Odds Ratio (OR) calculation. We grouped patients according to diagnosis. GD occurred in 9 eyes affected by BK and 19 by FD (p=0.003, OR = 0.25, 95% CI, 0.098-0.62). It was recovered with ARB. In BK, ARB correlated to complicated cataract extraction (p=0.04, OR = 7.83, 95% CI, 1.28 - 47.98) and aphakia (p=0.026, OR = 54.38, 95% CI, 2.51 - 11.76). In FD, ARB was associated to donor death for neoplasia (p=0.06, OR= 4.04, 95% CI, 1.06 - 15.37). No other differences were found. In conclusion, we could hypothesize that in FD patients, donor cancer therapy may play a role on altered corneal fibroblast metabolism, activating a synergetic effect between chemotherapy and genetic alteration of FD, which may lead to an altered adhesion of donor lenticule on recipient's stroma. In BK patients, complicated cataract extraction and aphakic status of recipient eye may contribute to altered adhesion of donor lenticule post-DSAEK
The role of computed tomography angiography 3D imaging in post-operative haemorrhage after groin mesh hernioplasty during anticoagulation therapy
No full textPost-operative groin and scrotal hematoma is an infrequent condition after inguinal hernia repair but its rate is
progressively rising due to the increase of patients with high bleeding risk (coagulopathy or antithrombotic therapy).
We therefore think that it is useful to share our recent experience of treatment of giant post-operative groin and scrotum
hematoma; this complication occurred after a Lichtenstein open hernia repair in a patient on antithrombotic therapy
(Warfarin®) due to congenital coagulopathy
The part-time work and job on call in JustEatTakeaway supplementary company agreement for Takeaway.com Express Italy (Just Eat group) riders
No full textThe comment deals with the part-time work regulation, contained, in particular, in Part II of the JustEatTakeaway supplementary company
agreement. The use of this instrument is expected to be massive, considering that it is, in the parties' plans, the common form of work in the company.
The author analyses the provisions contained in the collective agreement, especially in the light of the discipline contained in the CCNL Logistica, Trasporto, Merci e Spedizione and in the Protocol signed on 18 July 2018 for the same sector. The author also discusses the rules on overtime and supplementary work and the rules on intermittent work, which are also subject to specific contractual regulations

the working hours of riders. The Author illustrates the discipline contained in the CCNL Logistica,Trasporto, Merci e Spedizione and in the Protocol signed on July 18, 2018 for the same sector, to which the same company agreement in comment refers
Green blue Youth Vision 2030: nuove comunità culturali creative e sostenibili
No full textNel contesto europeo, la cultura svolge un ruolo cruciale nelle strategie di sviluppo sostenibile. Il framework “UNESCO Culture 2030” sottolinea che gli approcci culturali potrebbero supportare le politiche sostenibili anche attraverso il miglioramento dei comportamenti degli individui e delle comunità. In questa prospettiva, la ricerca si propone di rispondere alle seguenti domande: quali approcci culturali sono idonei a costruire una visione di sviluppo sostenibile quale bene comune? Quali azioni e strumenti possono essere applicati a scala locale per l’implementazione degli obiettivi dell’Agenda 2030? L'approccio metodologico “Green Blue Youth Vision 2030” esplora le proposte culturali di giovani esperti under 35, trasformando le diverse dimensioni del framework Culture 2030 in azioni e strumenti da sottoporre ai beneficiari diretti e potenziali dei “Green Blue Days”, il primo forum sulla sostenibilità sistemica al Sud Italia. I risultati della ricerca dimostrano il ruolo di comunità, cooperazione e creatività nel mettere in pratica una cultura della sostenibilità legata alla cura dello spazio collettivo
Tephrostratigraphy of paleoclimatic archives in central Mediterranean during the Bronze Age
No full textRe-examination of central Mediterranean paleoclimate archives on tephra layers indicates that three widely dispersed tephra layers occurred during the Bronze Age, namely Agnano Mt Spina from Campi Flegrei (ca. 4.4 cal ka BP), Avellino from Somma-Vesuvius (ca. 3.9 cal ka BP), and FL from Etna (ca. 3.3 cal ka BP). Stratigraphical correlations of selected archives using these tephra layers indicate that some records have severe chronological biases, posing important limitations to the use of these archives for defining the paleoclimate conditions during the Bronze Age. Regardless of the temporal mismatches, the Agnano Mt Spina tephra layer seems to have occurred at the beginning of a centennial scale period of climatic deterioration, while the Avellino tephra layer, taking place during a wetter period, seems to mark the end of this event. The dry event bounded by the two tephra layers seems to be correlated with the so-called “4.2 event”. Instead, the FL tephra from Etna seems to herald a new climatic deterioration at ca. 3.3–3.2 cal ka BP. Although the general frame is still incomplete, these three tephra layers appear to play a fundamental role in synchronizing archives, and can lead to the definition of a detailed paleoclimatic framework of the Bronze Age in the central Mediterranean area
Facilmente digeribile...ma non per la Corte di giustizia! Ovvero: della nozione di «informazioni sulla salute» nell'etichettatura delle bevande alcoliche secondo la normativa UE
No full textIn this article the Author comments on the recent sentence of the Court of Justice EU of 6 September 2012, Deutsches Weintor. After a general introduction of the issue and a summary of the grounds of the decision, the Author highlights problems with the interpretation of the Regulation (Ec) No 1924/06 given by the Court of Justice and finds it both too restrictive and in non-compliance with the principle of proportionality. The negative consequences of the sentence in the specific sector of the functional foodstuffs market are analysed, and the juridical evaluation also covers the Commission Regulation (Eu) No 432/2012 of 16 May 2012 establishing a list of permitted health claims made in foods, as well as the role of EFSA in the definition of the criterion to interpret the Regulation on nutritional and health claims. The article concludes with a request for a future revision of the jurisprudence and the general regulation of this matter in order to achieve a better equilibrium between the protection of health, consumer rights and the economic interests of businesses
Il diritto sindacale al tempo della crisi. Intervento eteronomo e profili di legittimità costituzionale
No full textThe essay explores some recent law reforms in the field of individual and collective labour relations and focuses on the lowering of the level of protectiveness towards workers they seem to foster as well as on their effect on the system of sources of regulation (i.e. the shift from legislative regulation to contractual norms; from nation-wide collective agreements to plant-level agreements). In this perspective, the author focuses on the consistence of these trends with constitutional principles and rules concerning trade union freedom and collective bargaining. To this end, the author offers an analysis of relevant doctrine and case law and suggests re-reading some basic decisions issued by the Constitutional Court over the time, arguing they still deserve due attention. Throughout his analysis, the author warns about the risk of considering obsolete fundamental principles and rights that are rather still of crucial importance in the current constitutional legal framework
