Le peculiarità dell'ordinamento sportivo
2016
The thesis aims to check whether the construction of the sporting law, identified by the majority of experts as an original system, with its own autonomy, is still relevant or should be considered outdated. After the analysis of the construction of the sporting law, gradually specified at national and supranational levels, the project deals with the principles established by the European and international law, in order to identify, in consideration of the interventions of the European institutions and the Lisbon Treaty (TFEU art.165). Both nationally and at the European level the sports law is strongly integrated in general law and, so, subjected to the relevant regulations. With the limit,…
Il valore sociale dello sport: un nuovo limite alla c.d. specificità?
2014
Nella sentenza in commento la Corte di giustizia colloca il valore sociale dello sport nell'ambito dell'inte- resse generale, in base al quale si giustifica una deroga alle disposizioni del Trattato. In tal modo pare su- perato il pregresso orientamento che riconduceva il valore sociale nel quadro della c.d. specificità dello sport: ambito, quest'ultimo, riservato alla piena autonomia degli organismi sportivi e come tale sottratto alla applicazione dei principi stabiliti dai Trattati europei e quindi alla giurisdizione della Corte, salvi i casi di emersione e rilevanza del profilo economico dello sport medesimo. Oggi la Corte ritiene che il ruolo so- ciale dello sport non implichi una esenz…
A Theoretical and Experimental Investigation of the Spectroscopic Properties of a DNA-Intercalator Salphen-Type ZnIIComplex
2014
The photophysical and DNA-binding properties of the cationic zinc(II) complex of 5-triethylammonium methyl salicylidene ortho-phenylenediiminato (ZnL 2 + ) were investi- gated by a combination of experimental and theoretical methods. DFT calculations were performed on both the ground and the first excited states of ZnL 2 + and on its possi- ble mono- and dioxidation products, both in vacuo and in selected solvents mimicked by the polarizable continuum model. Comparison of the calculated absorption and fluores- cence transitions with the corresponding experimental data led to the conclusion that visible light induces a two-elec- tron photooxidation process located on the phenylenediimi- nato…
First trap-assisted decay spectroscopy of the $$^{81}$$Ge ground state
2022
AbstractThe $$\beta $$ β -delayed $$\gamma $$ γ spectroscopy of $$^{81}$$ 81 As has been performed using a purified beam of $$^{81}$$ 81 Ge $$(9/2^+)$$ ( 9 / 2 + ) ground state at the Ion Guide Isotope Separator On-Line facility (IGISOL). The $$^{81}$$ 81 Ge$$^+$$ + ions were produced using proton-induced fission of $$^{232}$$ 232 Th and selected with the double Penning trap JYFLTRAP for the post-trap decay spectroscopy measurements. The low-spin $$(1/2^+)$$ ( 1 / 2 + ) isomeric-state ions $$^{81m}\hbox {Ge}^+$$ 81 m Ge + were not observed in the fission products. The intrinsic half-life of the $$^{81}$$ 81 Ge ground state has been determined as $$T_{1/2}=6.4(2)~\hbox {s}$$ T 1 / 2 = 6.4 ( …
Spectroscopic studies of semiconducting single-walled carbon nanotubes
2010
The unique nature of optical properties of single-walled carbon nanotubes (SWCNT), together with their promising potential applications, have created enormous interest towards the photophysics of SWCNT. Many aspects of carbon nanotubes originate from the electronic structure of carbon honeycomb lattice and one-dimensionality. SWCNTs exist in various chiral structures and diameters, which the optical and electrical properties are dependent on. It has been discovered that SWCNT excited states are excitonic with strong Coulomb interaction between the electron and the hole. However, many features of excitons are not yet well defined, such as absorption cross-sections, fluorescence quantum yield…
The everyday and spectacle of subdued citizenship in northern Uganda
2019
Drawing on ethnographic research in the Acholi town of Kitgum in northern Uganda, this chapter illustrates how citizenship practices are embedded in particular relationships between the state and its citizens. Two key arenas for learning are identified: the everyday, which in this region is tinged by memories of past violence and fears of its recurrence, and moments of spectacular state performance such as the burial of a prominent politician. The chapter shows how practices of citizenship are learned through embodied experiences: by taking part in public debate, by voting or by greeting a flag, but also by running away from a soldier or by staying quiet due to fear. The chapter’s overall a…

Chromatin Maturity Index (CMI) in unfixed and live spermatozoa and Aniline Blue (AB) stained as an additional evaluation parameter in idiopathic male…
2021
Study question: To investigate whether idiopathic male infertility may be due to the presence of histones in motile spermatozoa using a modified AB staining protocol. Summary answer: No correlation between CMI in live motile spermatozoa, DNA Fragmentation Index (DFI) and other conventional seminal parameters were found in male infertile patients. What is known already: The AB stain discriminates between lysine-rich histones and arginine/cysteine-rich protamines. Transition from histones to protamines during spermatogenesis remodels chromatin packaging and abnormalities in the substitution of those proteins maybe interfere with seminal parameters and affect male infertility. The correlation …
FSH administration reduces significantly sperm apoptosis only in the case of high DFI value: a study in idiopathic dispermic patients
2012
Introduction: In the last decades sperm DNA quality has been recognized as one of the most important markers of male reproductive potential (Lewis and Aitken, 2005; Ozmen, 2007; Tarozzi, 2007), in contrast to standard semen parameters as sperm density, motility and morphology, which do not act as powerful discriminators between fertile and infertile men. DNA damage in the male germ line is a major contributor to infertility, miscarriage and birth defects in the offspring. In animal models, it has been unequivocally demonstrated that the genetic integrity of the male germ line plays a major role in determining the normality of embryonic development. In humans, many studies showed that sperm …
