Electrochemically Triggered Co-Conformational Switching in a [2]catenane Comprising a Non-Symmetric Calix[6]arene Wheel and a Two-Station Oriented Macrocycle
Get PDFCatenanes with desymmetrized ring components can undergo co-conformational
rearrangements upon external stimulation and can form the basis for the development of molecular rotary motors. We describe the design, synthesis and properties of a [2]catenane consisting of a macrocycle—the ‘track’ ring—endowed with two distinct recognition sites (a bipyridinium and an ammonium) for a calix[6]arene—the ‘shuttle’ ring. By exploiting the ability of the calixarene to thread appropriate non-symmetric axles with directional selectivity, we assembled an oriented pseudorotaxane and converted it into the corresponding oriented catenane by intramolecular ring closing metathesis. Cyclic voltammetric experiments indicate that the calixarene wheel initially surrounds the bipyridinium site, moves away from it when it is reduced, and returns in the original position upon reoxidation. A comparison with appropriate model compounds shows that the presence of the ammonium station is necessary for the calixarene to leave the reduced bipyridinium site
Diritto con musica e letteratura: è possibile raccontare lo sviluppo del diritto?

To do so, it presents the evolution of this ‘movement’ passing by the American, European and Brazilian experiences to distinguish the studies that have been done so far from the thesis hereby presented. This thesis is based on the possibility to considering the musical lyrics as literary texts and understanding and describing development of the law starting from the particular cultural (literary) context from which law and other social rules emerge
MADFORWATER: WP2: Adaptation of wastewater treatment technologies for agricultural reuse: Task2.3: Agro-industrial wastewater treatment: Subtask2.3.1: Treatment of olive mill wastewater: procedure for the selection of the optimal sorbent for phenolic compounds recovery
No full textA procedure for the selection of the optimal adsorbent for phenolic compounds (PC) recovery from PC-rich wastes and wastewaters was innovatively proposed and applied to compare 4 neutral resins (Amberlite XAD 16, Optipore SD-2, Amberlite FPX66, Amberlite XAD761) and 1 ion-exchange resin (IRA958 Cl) for PC recovery from a Tunisian olive mill wastewater (OMW)
Valorisation of olive mill wastewater by phenolic compounds adsorption: development and application of a procedure for adsorbent selection
Get PDFA procedure for the selection of the optimal adsorbent for phenolic compounds (PC) recovery from PC-rich wastes and wastewaters was innovatively proposed and applied to compare 4 neutral resins (Amberlite XAD16N, Optipore SD-2, Amberlite FPX66, Amberlite XAD761) and 1 ion-exchange resin (Amberlite IRA958 Cl) for PC recovery from a Tunisian olive mill wastewater (OMW). In the initial batch isotherm tests a neutral resin (XAD16N) performed best thanks to its high PC sorption capacity (81 mgPC/gdry resin) and PC content in the sorbed product (0.19 gPC/gvolatile solids). Also ion-exchange resin IRA958, used in OH form in this work, resulted interesting thanks to its satisfactory performances and very low cost (8 €/L). These two pre-selected resins were further compared by means of continuous-flow adsorption/desorption tests conducted in a 1-m packed column. The results indicate that if a low (20%) breakpoint is selected, XAD16N leads to a PC-richer sorbed product (0.14 gPC/gvolatile solids) and a higher operating capacity (0.30) than IRA958. Conversely, if a very high (90%) breakpoint is selected, the two resins produce similar desorbed products in terms of both PC content (0.19-0.21 gPC/gvolatile solids) and antioxidant capacity (4.6-4.9 gascorbic acid equivalent/gPC). Resin-specific dynamic desorption procedures led to very high PC desorption yields (87-95%). The identification of the actual PCs present in the final desorbed product indicated for XAD16N a higher capacity to preserve the integrity of the PC mixture of the studied OMW. OMW microfiltration (0.2 μm pore-size) led to a 99.8% suspended solid removal - thus protecting the packed column from potential clogging - with a very low PC loss
Ontologia e teleologia del giardino
Get PDFQuesto articolo fa parte dell’ottavo numero dei Quaderni di PsicoArt che include molti dei testi raccolti dieci anni fa da Gianni Scalia e Raffaele Milani: erano gli anni in cui si discuteva assai di paesaggio, natura, ambiente, territorio, luogo, spazio, cercando di comprenderne il senso e il valore, la relazione e l’arricchimento reciproco in un ampio registro semantico. Si dà ora forma ai materiali di quella ricerca, conservandone lo spirito. È un viaggio che muove dal lontano mondo greco-latino e arriva alle tesi romantiche sulla natura inserendovi anche un confronto tra le culture: indiana, cinese, giapponese. Autorevoli studiosi commentano filosofi e scrittori, correnti letterarie e di pensiero della più alta tradizione mondiale, affinché la dignità dell’antico possa significare il futuro

Informal Employment Relationships and the Labor Market: Is there Segmentation in Ukraine?
Get PDFOne of the most important factors that determine individuals’ quality of life and wellbeing is their position in the labor market and the type of jobs that they hold. When workers are rationed out of the formal segment of the labor market against their will, i.e., the labor market is segmented, their quality of life is limited, and their wellbeing is reduced. When they can freely choose between a formal or informal employment relationship, i.e., the labor market is integrated, their wellbeing can reach high levels even in the presence of informal employment. We, therefore, test whether the Ukrainian labor market is segmented along the formal-informal divide, slicing the data by gender and age. The analysis that we perform consist in the analysis of short-term and medium-term transitions between five employment states, unemployment and inactivity. We also analyze wage gaps of mean hourly earnings and across the entire hourly earnings distribution, controlling for time-invariant unobserved heterogeneity. According to our results segmentation is present for dependent employees: for a large part of informal employees informal employment is used as a waiting stage to enter formal salaried employment and is not voluntarily chosen. As far as self-employment is concerned the evidence is mixed regarding in the Ukrainian labor market. This heterogeneity in outcomes implies that not all informal work is associated with a low quality of life and reduced wellbeing in post-transition economies
Securing borders, saving migrants: the EU's security dilemma in the twenty-first century
Get PDFFor the EU, though, coping with the challenge of migration has a double
meaning: first, it implies envisaging solutions to a phenomenon that is here to
stay. Second, it entails figuring out which kind of security actor the EU is and is
likely to be in the future: will it be an inward- looking entity committed to ‘securing’
its homeland; or will it consider the security of migrants (and their rights) as
equally relevant to the values it upholds and the external image it wants to
project? Both objectives are strategic, as they pertain to the future of the EU and
the European capability to face core challenges collectively. Hence, this chapter
focuses on the key questions framing the contributions to this collection: What is
the EU’s ambition as a security actor in the migration domain? Is the EU an
autonomous security actor vis- à-vis its member states in this domain? Is the
EU strategy with respect to migration internally consistent and comprehensive?
Does the EU deliver policies consistent with its security rhetoric and, if not, why
and with what consequences

This essay focuses on some high literary works in referring on a very long time.
Through the Aeschylus’ tragedies and the Homeric epic, we can understand the slow rise of a new legal culture that surpasses the archaic one, dominated by the principle of vengeance. Machiavelli’s works show how the change of cultural paradigms leads also the change of political and legal orders. Such as we note the work by the jurist Gio-vanni Battista De Luca, from the 1600’s, for its focus on legal language and jurist as direct indicators of the evolution of the juridical order, to describe juridical culture in that era the contribution by Alessandro Manzoni is more important.
High literature contributes to our understanding of the social dimension of juridical phenomena
