Phenolic composition of Nebbiolo grapes: impact of solar radiation
Grapes (Vitis vinifera L.) are fruits rich in polyphenols; the phenolic composition of grape is very complex, including monomeric and/or polymeric molecules as anthocyanins, flavan-3-ols, flavonols, dihydroflavonols, various phenolic acids and hydroxystilbenes. Phenolic composition of grapes varies depending on several factors such as the effect of vintage, soil, temperature, luminosity, cultural practices and developmental stage (1).
Aim of this work was to characterize the phenolic composition of Nebbiolo grapes from Piedmont, evaluating the influence of solar radiation. The vineyards for the samples collection were selected in four different areas, namely Piobesi d’Alba (CN), Barolo (CN), La Morra (CN) and Ghemme (NO).
First, the amount of incident radiation upon the surface of grapevine rows, taking into account their mutual shading, was calculated. For each vineyard, a radiation map highlighting homogeneous radiation areas was produced; the maps were then employed to carry out the sampling in areas characterized by different class of radiation (in each vineyard 2 or 3 points for both highest and lowest radiation area were selected).
The phenolic fraction of different grape samples (harvested at the physiological ripeness) was characterized for total polyphenols, anthocyanins and tannins, the antioxidant activity (DPPH method) and the chromatic characteristics. Liquid chromatography (RP-HPLC/DAD) has been also applied for the characterization of individual polyphenols.
The composition of grape samples varied depending on the different radiation areas; however, different behaviors were observed also considering samples from different vineyards. In the locality of Ghemme, the highest values for both polyphenols and antioxidant activity were observed in correspondence of the higher radiation area; samples from the Southern Piedmont generally showed an inverse tendency

Characterization of Italian rice varieties and their by-products
Rice (Oryza sativa L.) is one of the world’s most important cereal crops providing a staple food source for more than 50% of the world’s population. The extent of rice cultivation in Italy is of significant importance: with 1.3 million tons a year of finished product, Italy is not only Europe’s leading producer, but one of the major non-Asian producers, after Brazil and USA (1).
Pigmented rice is widely known as enriched rice for taste and health improvements; primarily produced in Southeastern Asia, recently various pigmented rice cultivar have been developed and cultivated in Italy.
Rice bran, a by-product of the rice milling industry, contributes about 10% to the weight of the grain. Because it contains high amounts of structurally different bioactive compounds, bran from pigmented rice varieties has the potential to serve as a functional food that can promote human health (2).
The main scope of this work was to characterize some both pigmented and white Italian varieties of rice grown in Piedmont (black varieties: Venere, Artemide, Nerone and Otello; red varieties: Ermes, Russ and Rosso Italiano; white varieties: Carnise, Carnise precoce and Selenio (this last one only partially refined)). Different by-products from rice milling were also investigated, husks from shelling process and bran from the pearling (namely “pula” and “farinaccio” from the first and the second part of the process, respectively).
Rice samples were characterized for the proximate composition, the antioxidant activity (DPPH radical scavenging) and the phenolic composition (phenolic acids, flavonoids and anthocyanins).
The higher antioxidant activity and phenolic content were observed for by-products obtained from the pearling process, particularly in the case of pigmented rice (black and red bran), while husks (from white rice) showed the highest fiber content (about 74%). Anthocyanins were determined only in black samples, having evidenced the prevalence of cyanidin-3-glucoside in all the varieties analyzed, while total condensed tannins were prevalent in red bran and Rosso Italiano variety (about 30 and 14 mg/g, respectively)

La lunga estate calda del diritto del lavoro: dall'accordo interconfederale del 28 giugno 2011 all'art. 8, d. l. n. 138/2011
Il saggio si occupa dell'importante accordo interconfederale del 28 giugno 2011 e dell'art. 8, d. l. n. 138/2011. Entrambi gli atti normativi sospingono il sistema italiano di relazioni industriali verso il decentramento della contrattazione collettiva. In particolare, l'autore suggerisce un'interpretazione cauta dell'art. 8 per evitare rischi di illegittimità costituzionale.The article deals with the important nationwide collective agreement of 28th June 2011 and art. 8, decree law n. 138/2011. Both these normative acts push Italian industrial relations towards decentralisation of the collective bargaining. The author suggests a very cautious interpretation of art. 8, in order to minimise the risk of uncostitutionality
Clausole di forza maggiore, "hardship" e assenza di effetti sfavorevoli: riflessioni ai tempi della "grande epidemia".
La recente diffusione del “Covid-19” ha sollevato diversi problemi, alcuni già noti in dottrina mentre altri più nuovi, in merito alla gestione del rischio contrattuale in capo alle parti. Ricorrendo a un’analisi comparata e a una prospettiva internazionale, il saggio prende in considerazioni diverse aree del c.d. “diritto degli affari” per capire se – a fronte di una circostanza così eccezionale ed imprevista come il virus “C-19” – sia possibile ricorrere all’utilizzo di strumenti negoziali, anche pattizi, per garantire una protezione alle parti del contratto. L’analisi prende in esame diversi ambiti spaziando dalla contrattualistica commerciale al diritto societario; in quest’ultimo caso, vengono svolte alcune riflessioni con riguardo ai contratti di compravendita di partecipazioni, al ricorso alle joint ventures come strumento per attuare investimenti diretti in Paesi terzi e ai finanziamenti d’impresa. Sono prese in considerazione, in particolare, le clausole di forza maggiore, le c.d. «hardship clauses» e le clausole di “mutamento avverso significativo” già note alla prassi contrattuale ma oggetto di esame sotto un nuovo punto di vista. L’autore prende altresì in considerazione le più recenti esperienze registratesi a livello internazionale in merito ad iniziative di note istituzioni europee (European Law Institute) e internazionali (International Chamber of Commerce) per mettere a confronto le previsioni da esse elaborate per far fronte all’attuale situazione emergenziale: ne emergono diversificate modalità di bilanciamento degli interessi in gioco per lo più condivisibili, ma la cui tenuta necessita, secondo l’autore, una verifica “sul campo” e un esame di compatibilità con le regole della legge applicabile. L’ultima parte del lavoro è infine dedicata a investigare – in una prospettiva nuova, data dalla situazione sanitaria in essere – la possibile individuazione di regole o principi che, nell’ordinamento interno, possano fondare obblighi di rinegoziazione di un contratto.The recent diffusion of the “Covid-19” virus raised serious concerns about the management of business agreements and the rate of contractual protection allocated to the parties of a contract. Adopting an international prospective, this essay investigates several areas of business law to understand if the contractual risk due to such an exceptional and unforeseen circumstance (or other circumstance of similar nature) can be mitigated from a contractual point of view. The analysis covers several fields of business law from contractual law (facility agreements and commercial contracts) to corporate law (share purchase agreements; JV agreements in “foreign direct investments”). Protection mechanisms diffused in the business practice – such as “force majeure clauses”, “hardship clauses” and “material adverse change” provisions – are compared to find out common elements. The author also consider different approaches recently recorded in the international practice by well-known institution (European Law Institute and International Chamber of Commerce) about the use of these clauses as contractual tools against the current pandemic situation. The last part of the essay is dedicated to the investigation of general principles that may substantiate a duty of re-negotiation
Magnetic and ligand field properties of copper at the interfaces of (CaCuO2)(n)/(SrTiO3)(n) superlattices
Using high-resolution resonant inelastic x-ray scattering (RIXS) excited at the Cu L-3 edge we have investigated the ligand field (dd) and magnetic excitations in (CaCuO2)(n)/(SrTiO3)(n) superlattices (n = 2,3) and compared them to those of a 14-nm-thick CaCuO2 film. The dd excitation spectrum reveals a pyramidal coordination of Cu ions at the CaCuO2/SrTiO3 interfaces. In the three samples, spin excitations are in the form of dispersing magnons, with similar spectral intensity but reduced dynamics in SLs with respect to pure CaCuO2. By fitting the dispersions within linear spin wave theory we have obtained the leading term of the in-plane superexchange parameters: J = 127 meV, 138 meV, and 157 meV for n = 2, 3 SLs, and CaCuO2, respectively. These results demonstrate that the antiferromagnetic order is preserved in these SLs down to very small cuprate layer thickness and despite the chemical and structural alterations at the interface. This finding opens the way to the production of artificial Cu-based high-temperature superconductors where the charge reservoir layer is constituted by the interface itself
