Incantesimi e rituali magici nelle tradizioni germaniche medievali: una introduzione
2021
The approach to charms and magical formulas of the Germanic world has developed on an evolutionary path that has from time to time favoured perspectives of different scientific categories, and has been faced on philological, linguistic, semantic-pragmatic, semiotic and historical-literary basis. Starting from different types of criteria and parameters, research has proposed in the past various classifications of charms, intended as specific textual forms, which are identified by the presence of characteristic contents and structural elements. Given the fluidity of matter, the phenomenon of charms and magical formulas of the Germanic area should be seen in a dynamic key, applying different i…
I Salmi e la Qabbala
2019
La qabbalah è un argomento particolarmente ampio e complesso; con tale termine si indica non un'unica dottrina ma l’insieme multiforme dell’elaborazione degli insegnamenti esoterici del misticismo ebraico, soprattutto nelle forme che questi assunsero nel medioevo, a partire dalla fine del dodicesimo secolo. In questo articolo si metteranno in luce solo alcuni tratti, in particolare la relazione con la riflessione speculativa, con la filosofia, e con il risvolto pratico, nello specifico con la preghiera .
Correlated randomness and switching phenomena
2010
One challenge of biology, medicine, and economics is that the systems treated by these serious scientific disciplines have no perfect metronome in time and no perfect spatial architecture—crystalline or otherwise. Nonetheless, as if by magic, out of nothing but randomness one finds remarkably fine-tuned processes in time and remarkably fine-tuned structures in space. Further, many of these processes and structures have the remarkable feature of “switching” from one behavior to another as if by magic. The past century has, philosophically, been concerned with placing aside the human tendency to see the universe as a fine-tuned machine. Here we will address the challenge of uncovering how, th…
Spectroscopic and conformational properties of size-fractions separated from a lignite humic acid
2007
Abstract A lignite humic acid (HA) was fractionated by preparative high performance size-exclusion chromatography (HPSEC) in seven different size-fractions. The size-fractions were characterized by cross polarization (CP) magic angle spinning (MAS) 13 C NMR spectroscopy and a further analytical HPSEC elution under UV and fluorescence detection. The alkyl hydrophobic components mainly distributed in the largest molecular-size-fraction, whereas the amount of oxidized carbons increased with decreasing size of fractions. Cross polarization time ( T CH ) and proton spin-lattice relaxation time in the rotating frame ( T 1 ρ (H)) were measured from variable contact time (VCT) experiments. The bulk…
Metal clusters on an inert surface: A simple model
1997
The shapes of metal clusters (with 2 to 14 valence electrons) on an inert surface are studied with a simple model based on the ultimate jellium model. It is shown that within certain approximations the surface-cluster interaction can be described with an external potential in the Kohn-Sham method. No restrictions for the cluster geometry are imposed. The results show that depending on the strength of the interaction and on the size of the cluster, the ground state is either planar or three-dimensional, but in many cases both geometries are stable and there is a marked energy barrier between them. The results agree qualitatively with ab initio calculations of Na clusters on a NaCl(100) surfa…
A Straightforward Approach to Multifunctional Graphene
2019
Graphene has been covalently functionalized through a one-pot reductive pathway using graphite intercalation compounds (GICs), in particular KC8 , with three different orthogonally protected derivatives of 4-aminobenzylamine. This novel multifunctional platform exhibits excellent bulk functionalization homogeneity (Hbulk ) and degree of addition while preserving the chemical functionalities of the organic addends through different protecting groups, namely: tert-butyloxycarbonyl (Boc), benzyloxycarbonyl (Cbz) and phthalimide (Pht). We have employed (temperature-dependent) statistical Raman spectroscopy (SRS), X-ray photoelectron spectroscopy (XPS), magic angle spinning solid state 13 C NMR …
Understanding the physicochemical properties of olive kernel to be used as a potential tool in the development of phenol-formaldehyde wood adhesive
2015
Abstract During olive oil production process, a great number of by-products are generated, including olive kernel. These by-products can be used for the development of new products for use in many different industrial applications. The evaluation of the physicochemical properties of these by-products constitutes a key factor in evaluating the potential reutilization of olive oil by-products. In the present study, the physicochemical properties of olive kernel were analyzed. Fourier transform infrared spectroscopy (FT-IR), cross-polarization magic angle spinning 13 C nuclear magnetic resonance (CP/MAS 13 C NMR), Brunauer, Emmett and Teller (BET), scanning electron microscopy (SEM) and thermo…
Neoextractivism, or the birth of magical realism as world literature
2021
In recent years, literary criticism has shown increased interest towards the manner in which fiction depicts (neo)extractivism as a set of practices whereby large quantities of natural resources ar...
Thomas Manns "Der Zauberberg" in der polnischen Fassung. Übersetzungsgeschichte und Nachwirkung
2017
Niniejszy artykuł prezentuje rozważania wstępne autorki związane z planowaną rozprawą habilitacyjną, której celem jest zrekonstruowanie historii polskiego przekładu powieści Der Zauberberg (Czarodziejska góra) Thomasa Manna oraz zanalizowanie jego oddziaływania na polską recepcję utworu. Ze względu na fakt, że obie części powieści zostały przełożone przez różnych tłumaczy, a tom drugi doczekał się dwóch wersji przekładu (z roku 1930 oraz z 1953), powstaje przy tym fundamentalne pytanie o spójność wyłaniającego się z przekładu światopoglądu dzieła. Dalsza część artykułu przybliża pokrótce sylwetki autorów polskiej wersji Czarodziejskiej góry. W końcowej części sformułowano zasadnicze kwestie…
