The next generation of laser spectroscopy experiments using light muonic atoms

2018

Precision spectroscopy of light muonic atoms provides unique information about the atomic and nuclear structure of these systems and thus represents a way to access fundamental interactions, properties and constants. One application comprises the determination of absolute nuclear charge radii with unprecedented accuracy from measurements of the 2S - 2P Lamb shift. Here, we review recent results of nuclear charge radii extracted from muonic hydrogen and helium spectroscopy and present experiment proposals to access light muonic atoms with Z ≥ 3. In addition, our approaches towards a precise measurement of the Zemach radii in muonic hydrogen (μp) and helium (μ 3He+) are discussed. These resul…

Il tesoro recuperato. L’inventario dei beni delle regine di Sicilia confiscati a Manfredi Alagona nel 1393

2007

Partendo dal ritrovamento, presso l’Archivio di Stato di Palermo, di un inventario di beni confiscati a Manfredi Alagona nel 1393, il lavoro ricostruisce il percorso del tesoro delle regine siciliane (Costanza d’Aragona, Maria di Sicilia) che era stato incamerato dagli Alagona, potente famiglia di origine aragonese trapiantata in Sicilia. Uno studio dettagliato degli oggetti inventariati permette l’analisi di vari aspetti legati al costume e alla società sul finire del XIV secolo, dall’abbigliamento alla tavola, dal gusto e la moda del tempo alla cura della persona, dalla passione per i gioielli al culto per le reliquie. Beginning from the discovery, in the “Archivio di Stato” of Palermo, o…

Hopf bifurcation at infinity for planar vector fields

2007

We study, from a new point of view, families of planar vector fields without singularities $ \{ X_{\mu}$  &nbsp:&nbsp  $-\varepsilon < \mu < \varepsilon\} $ defined on the complement of an open ball centered at the origin such that, at $\mu=0$, infinity changes from repellor to attractor, or vice versa. We also study a sort of local stability of some $C^1$ planar vector fields around infinity.

The Contribution of the Inter-American Human Rights Bodies to Evolving International Law on Indigenous Rights over Lands and Natural Resources

2010

AbstractBecause of the special relationship with land that characterises indigenous groups, rights over land and natural resources are at the heart of indigenous claims under international law. The Inter-American Commission on Human Rights and the Inter-American Court have developed a copious jurisprudence on the subject matter and contributed to the establishment of certain minimum indigenous peoples' land rights under customary international law. This article analyses the Inter-American judicial discourse on land issues in the light of the current status of relevant international law and reflects upon the potential contribution of the former to the further development of the latter. It fo…

El inicio de la vida humana y el alcance de su protección jurídica en la jurisprudencia europea e internacional

2014

The international human rights treaties recognize the right to life, but most of them do not determine if the unborn is within its scope and what the degree of protection. Given this lack of specificity, the interpretation and application of this fundamental right by its supervisory bodies is particularly important. The analysis of existing case law about it - mainly from Europe - will enable us to contribute to the definition of subjective and objective scope of the protection of the unborn.

The Long Route Towards a Widespread European Culture of Alternatives to Immigration Detention

2016

The aim of this article is to provide an analysis of the application by some European Union countries of alternative measures to detention of migrants. Sections 2 and 3 indicate, in line with European normatives and with detention being a measure of last resort, that Member States having ascertained that there are grounds for the detention of migrants, should evaluate whether the aims pursued can be achieved through a less coercive measure which respects the fundamental rights of individuals. Unfortunately, as examined in Section 4, analysis of most European countries’ law reveals an unsatisfactory application of alternative measures to detention. As in, for example, Italy’s case, whose leg…

Synthesis of polymer nanogels by electro-Fenton process: investigation of the effect of main operation parameters

2017

Recently, electro-Fenton (EF) process has been shown as a promising, facile, effective, low cost and environmentally-friendly alternative for synthesizing polymer nanogels suitable as biocompatible nanocarriers for emerging biomedical applications. Here, the electrochemically-assisted modification of poly(vinylpyrrolidone) (PVP) by EF process was studied to assess the role of key operation parameters for a precise modulation of polymer crosslinking and its functionalization with [sbnd]COOH and succinimide groups. The dimensions of the nanogels, in terms of hydrodynamic radius (Rh) and weight-average molecular weight (Mw), can be tuned up by controlling the electrolysis time, current density…

Xyloglucan-based hydrogel films for the design of "smart" bandages

2016

A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time the way most wounds do. Chronic wounds mostly affect people over the age of 60, but a significant proportion is becoming radiation induced chronic wounds caused by cancer radiotherapy. Hydrogels are often used as dressings in the management of a variety of wounds. These materials can help to maintain a moist wound environment, promote natural debridement, hydrate necrotic tissue, absorb slough and exudates.We are developing hydrogel dressings that can enable constant monitoring of selected key parameters through embedded radio-sensors, providing information on the progress of the re…

Development and characterization of xyloglucan-poly(vinyl alcohol) hydrogel membrane for wireless smart wound dressings

2018

Research which addresses advanced wound management can contribute to the needs of modern healthcare, especially in situations that require continuous monitoring, analysis, responsive therapeutic treatments and data recording. The development of “smart” bandages and dressings that can remotely monitor relevant parameters for the wound healing process without a hospital intervention can be very useful tools for patients and physicians and for advancing the understanding of the healing process. In the present work, biocompatible xyloglucan/poly(vinyl alcohol) hydrogels are being developed as smart wound dressings that, in addition to the traditional favorable properties of hydrogels as skin ca…
