A defence of determinism in late Wyclif attributed to Peter Payne. In this essay is presented the edition of a short tract of natural theology based on the only two extant copies preserved in mss. ...Praha, Národní knihovna, V.F.9, ff. 68v-75v and Wien, Österreichische Nationalbibliothek, 4937, ff. 28r-34v. It is introduced by a historical and philological note. A defence of John Wyclif’s views on future contingents condemned at the Council of Constance in 1415, the tract turns out to be a startling profession of crude determinism, so radical that it would hardly have been upheld by Wyclif even in his later and most controversial writings. The anonymous tract can be plausibly ascribed to Peter Payne, an Oxford Wycliffite who left England possibly to escape prosecution and reached Prague only after Hus’s departure for Constance (11 October 1414). Probably composed from late 1419 to early 1420, when Wyclif’s theological views were the object of harsh criticism by many masters at the University of Prague, the tract has a literary form similar to that of a determinatio, the answer given by a master to a question at the end of a disputation. Hence, it contains eighteen arguments in support of Wyclif’s thesis that “everything that will come to pass, will come to pass by absolute necessity” and six arguments against this thesis, followed by relevant rejections. As to the writing technique, Payne draws a significant amount of textual materials from several sources without citing them: namely Wyclif, Thomas Aquinas, and Jan Hus.

Per ogni percorso, vengono presentati alcuni possibili legami con i materiali creati all’interno del progetto MaMa – Matematica per la scuola elementare, che possono aiutare il docente per la progettazione di tali percorsi, consentendo di alternare attività di scoperta, concrete e manipolative, con momenti di riflessione e allenamento.
This article sketches the activities undertaken by the experts of the Rotary Club Roma Castelli Romani aimed at safeguard and recuperate the original artistic value of the Fountain of Piazza Castel ...gandolfo. Utilizing modern 3D scanning techniques a first phase have seen the analysis of the fountain in order to better understand the decay reasons of the stone and in order to reconstruct the border profiles for a subsequent phase of restauration. New promising techniques of restauration will be considered.
Ferritic stainless steel (FSS) is one of the high-temperature materials, used in many industries for sustainable applications such as power plants, automotive, offshore and chemical industries. ...Joining these materials is challenging due to the formation of an intermetallic and the grain growth with high-heat-input welding methods. Laser beam welding (LBW) that uses a low heat input was used successfully to join AISI 409 FSS tubes. In this work the welding speed and focal distance were varied as per a two-factor, three-level face-centred central composite design (FCCCD) to join AISI 409 FSS. A numerical model was developed to correlate the relationship between the ultimate tensile strength (UTS) and LBW process parameters. The validation of the developed model was carried out using the analysis of variance. Both welding speed and focal distance have a significant effect on determining the UTS. The optimised process parameters provided for a better UTS as reported in this paper.
Six letters from Giulio Preti to Giovanni Maria Bertin. Written during and after the second world war, these letters show the young Preti and his first steps as a critical empiricist.
Od prve koronarne angioplastike leta 1977 preko femoralnega pristopa je intervencijska kardiologija drastično spremenila zdravljenje ishemične bolezni srca. Prvotna perkutana transluminalna ...angioplastika z uporabo navadnih balonskih katetrov je sčasoma postala le pomožna tehnika za pripravo žilne spremembe in optimiziranje vstavljene žilne opornice. S pojavom navadnih žilnih opornic smo izboljšali rezultate na račun zmanjšanega elastičnega odsunka, poškodbe in konstriktivnega remodeliranja koronarnih arterij, z razvojem antiagregacijske terapije pa dosegli manjše število tromboz v žilnih opornicah. Ob nadaljnjih raziskavah neointimalne hiperplazije so se pojavile metode za lokalno apliciranje antiproliferacijskih zdravil. Razvile so se z zdravili prevlečene opornice, ki so leta 2019 postale novi zlati standard. Ob uporabi modernejših materialov so poskrbele za izboljšanje rezultatov na račun zmanjšanja neointimalne hiperplazije in števila zapletov. A kljub temu so še vedno tujek v žilni steni, ki spodbuja kronično vnetje, neoaterosklerozo, s tem pa restenozo ter zelo pozne pojave tromboze. To spoznanje zadnja leta vodi v razvijanje tehnik, ki bi za sabo pustile čim manj tujega materiala oziroma bi bil le-ta čimbolj biološko kompatibilen. Ob razvoju razgradljivih žilnih opornic so ena obetajočih terapevtskih možnosti z zdravili prevlečeni balonski katetri, ki razširijo žilno svetlino in lokalno aplicirajo antiproliferativno zdravilo na samo mesto spremembe brez uporabe opornice, ki bi ostala v žilni steni in spodbujala vnetje.

In order to cut their carbon footprint and promote environmental sustainability, the majority of businesses have now turned towards sustainable practises in their manufacturing processes and supply ...networks. The use of sustainable materials has drawn a lot of attention recently as a crucial step in accomplishing these goals. Choosing the material that is most suited for a product can be difficult, despite the fact that there are many sustainable materials available. This study uses machine learning – a random forest algorithm and multi-criteria decision analysis (MCDA) to optimise the use of sustainable materials in supply-chain operations. The study uses machine learning algorithms to analyse data on different sustainable materials, their characteristics and their effects on the environment. The study also investigates how an optimised material selection affects the whole supply chain, including the production, packing and shipping operations. The research offers a complete strategy for reducing the environmental effect of industrial processes by combining approaches from material engineering, supply chain management and machine learning. The novelty of this work resides in its integration of material engineering and machine learning strategies to enhance the supply chain choice of sustainable materials. As a notable example, the study highlights the potential of mycelium as a sustainable material for air conditioner components. Mycelium’s unique properties, such as its biodegradability, lightweight nature and adaptability position it as a promising candidate, enhancing the environmental profile of air conditioners. By incorporating mycelium-based components, manufacturers can significantly reduce carbon emissions, resource consumption and waste generation throughout a product’s lifecycle. This investigation underscores both the viability of mycelium and the broader significance of innovative material choices in reshaping industries towards a more sustainable future. Through such advances, this research not only contributes to the air conditioning sector but also establishes a paradigm for sustainable material adoption with far-reaching positive implications.
The paper describes the production of an AlSi7Mg cast alloy with Li additions and the reactions of the melt with different moulding materials. It is known that Li is very reactive and tends to form ...various reaction products such as oxides, gases, etc., which can influence the casting quality. The aim of the research was to find a suitable way to produce such an alloy and to describe the reaction products that are formed between the melt and the moulding material and thus to find a suitable moulding material for processing Al cast alloys with Li additions. The melt was produced in an induction furnace under an inert atmosphere. After melting, 1 w/% Li was added and the melt was cast into five different mould materials consisting of graphite, steel, a CO2 sand mixture, Croning mixture and calcium silicate materials. In the last three cases, various alcohol-based coatings were also used, such as graphite, zirconium oxide-graphite coating and aluminate-graphite filler coating. The results showed that the reaction products in the form of powder on the casting surfaces and the gas porosity in the castings occurred in the cast of a calcium silicate mould and sand mould mixtures. In the case of graphite and steel moulds, the casting surfaces were not oxidised, with no reaction products, and no gas porosity.
The paper analyses the debate in Sicily on the construction of the monumental colonnaded porticoes that characterise the facades of public edifices built on the island from the post- Unification ...period to the Fascist regime. The pronao of the Massimo Theatre in Palermo (from 1875) marks the climax of a cultural movement, which, for almost a century, was to associate the neo-Greek style with public buildings and the material of choice of Sicily’s church building tradition in a deterministic manner. Calcarenite was used to build the peristyles of the temples of the archaic and classical age, with imposing, tapered and grooved columns consisting of overlapping sections. In the Fascist period, and in the age of reinforced concrete buildings, the construction of the Court House in Messina (from 1923) became a topic of discussion in the debate at national level. The subsequent use of local materials, some of which of more recent extraction and processing, together with reinforced concrete, contributed to distorting the “archaeological” style of the initial projects sponsored by local authorities, towards modern and abstract compositions, as in the case of the construction of the Post Office Building in Palermo (from 1933), or towards compromise solutions, as in the case of the Court House in Catania (from 1937). The solutions investigated in any case required engineering and technological advances to allow the buildings to achieve a new monumental scale.
