Denunce anonime e attività "pre-procedimentale" del pubblico ministero

2006

Di fronte a un panorama giurisprudenziale che sancisce la nullità dei decreti di perquisizione e sequestro emanati a seguito di una denuncia anonima, la sentenza in commento rappresenta una meteora pericolosa che potrebbe legittimare attività poste in essere a iniziativa della polizia giudiziaria e finanche del pubblico ministero sostanzialmente ricusate dalla regola esclusoria che, pure nel sistema vigente, si è voluto adottare in tema di anonimi. Tuttavia, la chiusura all'anonimo non è stata prevista come assoluta, ma si è cercato di salvaguardare la possibile plausibilità del suo contenuto . Qui il vero nodo della querelle: le modalità concrete dell'utilizzo della denuncia anonima, sotto…

Development and Optimization of Pre-Concentration Procedure of Rare-Earth Elements (REEs) in Their Minerals, Using Microwave - Assisted Sample Dissol…

2015

Abstract The aim of this research was to develop and optimize a procedure for determination of REEs in xenotime and monazite samples collected from Bangka Island, which were compared to Standard Monazite (71 AG) of Bureau of Analyzed Samples, London. ICP-OES method was used for the determination. The samples were dried and sterilized by heating for a week at 110 °C, before digesting with nitric acid and hydrofluoric acid, using a microwave-assisted digestion system. After a careful line selection, at the detection limits for all REEs in the ng/mL the REEs were reliably obtained at the 0.09 – 38% level.

An XRD, TEM and Raman study of experimentally annealed natural monazite

2002

The healing of radiation damage in natural monazite has been experimentally studied in annealing experiments using XRD, TEM, Raman microprobe and cathodoluminescence analysis. The starting material was a chemically homogeneous monazite from a Brazilian pegmatite with a concordant U–Pb age of 474 ± 1 Ma and a U–Th/He age of 479 Ma. The monazite shows nm-scale defects induced by radioactive decay. The Xray pattern of the unheated starting material revealed two distinct monazite ''phases'' A and B with slightly different lattice parameters. Monazite A shows sharp reflections of high amplitudes and slightly expanded lattice parameters (1% in volume) compared to a standard monazite. Phase B exhi…

Pressure-Induced Transformations in PrVO4 and SmVO4 and Isolation of High-Pressure Metastable Phases

2013

Zircon-type PrVO4 and SmVO4 have been studied by high-pressure Raman spectroscopy up to 17 GPa. The occurrence of phase transitions has been detected when compression exceeds 6 GPa. The transformations are not reversible. Raman spectra of the high-pressure phases show similarities with those expected for a monazite-type phase in PrVO4 and a scheelite-type phase in SmVO4.The high-pressure phases have been also synthesized using a large-volume press and recovered at ambient conditions. X-ray diffraction measurements of the metastable products recovered after decompression confirms the monazite (PrVO4) and scheelite (SmVO4) structures of the high-pressure phases. Based upon optical properties …

Theoretical and experimental study of the structural stability ofTbPO4at high pressures

2010

We have performed a theoretical and experimental study of the structural stability of terbium phosphate at high pressures. Theoretical ab initio total-energy and lattice-dynamics calculations together with x-ray diffraction experiments have allowed us to completely characterize a phase transition at {approx}9.8 GPa from the zircon to the monazite structure. Furthermore, total-energy calculations have been performed to check the relative stability of 17 candidate structures at different pressures and allow us to propose the zircon {yields} monazite {yields} scheelite {yields} SrUO{sub 4}-type sequence of stable structures with increasing pressure. In this sequence, sixfold P coordination is …

Zircon to monazite phase transition in CeVO4: X-ray diffraction and Raman-scattering measurements

2011

X-ray diffraction and Raman-scattering measurements on cerium vanadate have been performed up to 12 and 16 GPa, respectively. Experiments reveal at 5.3 GPa the onset of a pressure-induced irreversible phase transition from the zircon to the monazite structure. Beyond this pressure, diffraction peaks and Raman-active modes of the monazite phase are measured. The zircon-to-monazite transition in CeVO4 is distinctive among the other rare-earth orthovanadates. We also observed softening of external translational T(Eg )a nd internalν2(B2g) bending modes. We attribute it to mechanical instabilities of zircon phase against the pressure-induced distortion. We additionally report lattice-dynamical a…

High-pressure structural transformations of PbCrO4 up to 51.2 GPa: An angle-dispersive synchrotron X-ray diffraction study

2014

Abstract We report on high-pressure X-ray diffraction measurements up to 51.2 GPa in PbCrO 4 at room temperature. Three high-pressure phases with structures different than the ambient-pressure monazite-type ( P 2 1 / n ) are reported. One phase transition was found at 3.8 GPa to an isomorphic structure to monazite. A second transition occurs at 11.1 GPa. After this transition, the coexistence of tetragonal ( I 4 1 / a ) and monoclinic ( P 2 1 ) structures is detected up to 21.1 GPa. Beyond this pressure and up to 51.2 GPa, only the high-pressure monoclinic phase is observed. Upon decompression all structural changes are reversible. Finally, the axial compressibilities for the different phas…

Slaveries and New Slaveries: Which Role for Human Dignity?

2020

This paper aims at reflecting on the role of the notion of "human dignity" with respect to slavery and new slaveries. First of all, a very brief reflection is carried out on the different legal meanings of the notion at stake in general terms (para. 2). On this basis, some remarks are developed with specific regard to the role played by dignity concerning new slaveries in the case law of international tribunals (European and Inter-American Courts of Human Rights, International Criminal Court, International Criminal Tribunal for the Former Yugoslavia: paras 3 and 4), particularly in the very recent case law of the European Court (para. 5) Such a role is far from being insignificant: the idea…

«The best interests of the child»: un’analisi giurisprudenziale comparata per un approfondimento concettuale

La vera innovazione apportata dalla Convenzione ONU diritti dell’infanzia del 1989 è, senz’altro, costituita dall’introduzione del concetto di “best interests of the child”. L’articolo 3 della CRC, infatti, sancisce espressamente che: «In all actions concerning children, whether undertaken by public or private social welfare institutions, courts of law, administrative authorities or legislative bodies, the best interests of the child shall be a primary consideration». Ma in cosa consiste realmente questo "interesse superiore del minore"? A chi spetta indicarne il contenuto? E soprattutto quali sono i parametri di riferimento da tenere in considerazione nel valutarlo? Nell’arco di pochi anni…
