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
Hydrogen‐Based Direct Reduction of Iron Oxides Pellets Modeling
No full textThe present study deals with the analyses of the direct reduction kinetics during the hydrogen reduction of industrial iron oxide pellets. Various types of pellets with different percentage of total iron content and metal oxides are examined. They are reduced at different temperatures and pressure (700-1100 degrees C and 1-6 bar) in hydrogen atmosphere. The reduction behavior is described in terms of time to reduction, rate of reduction, and kinetics constant. All the obtained results are analyzed through the employment of a commercial multiobjective optimization tool to precisely define the weight that each single parameter has on the reduction behavior. It is shown that from the point of view of the processing conditions, temperature is the main factor influencing the time to total reduction. From the point of view of the pellets properties, it is mainly influenced by the total iron percentage and then by porosity and basicity index. Also, the kinetics behavior is largely influenced by the reduction temperature even if it is mainly governed by the porosity and pores size from the point of view of the reduced pellets. The reduction rate is also mainly influenced by temperature and then by iron percentage, gas pressure, basicity index, and porosity
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 time regulation in JustEatTakeaway supplementary company agreement for Takeaway.com Express Italy (Just Eat group) riders
No full textConsidering that the regulation of the time and the possible economic relevance of the phases of waiting for delivery is a field of discussion still access regarding the work of riders, the Author analyzes, in detail, how the JustEatTakeway supplementary company agreement regulates
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
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
L'evoluzione della nozione di consumatore nel processo di integrazione europea
No full textThis article examines the evolution of the notion of "consumer" in the European Union law through an analysis of the EUCJ case law and secondary EU legislation, highlighting the most recent developments and the possible impact on the EU single market. The Author underlines, in particular, how the tendency to accentuate the abstraction of the notion of "consumer" can cause distortions which do not really help in the protection of consumer rights and create juridical uncertainty for business operators. Therefore it would be desirable to find a recylatoru and judicial approach that corresponds better to rhe reality of consumer dynamics in the framework of an increased sensitivity to individuals and their vulnerabilities
From "Cambozola" to "Toscoro". The Difficult Distinction between "Evocation" of a Protected Geographical Indication, "Product Affinity" and Misleading Commercial Practices
No full textIn this article the Author analyses the developments in the EU case-law on the notion of “evocation” of a geographical indication protected by the European Union in order to precisely define the elements of this particular case, distinguish it from the so-called “product affinity” and misleading conduct of juxtaposition and confusion as to the origin and identity of products, as well as analysing the boundary between “evocation” and “indirect comparative advertising” in the context of a market with increasing competition between PDO/PGI products and similar- generic products
