The Slave Coasts. Transnational Sexual Exploitation from Nigeria to Italy. From human trafficking to human rights

2019

This research intends to open a global debate on the current strong link between migration and prostitution on the basis of the reality observed in Palermo in the timespan 2015-2017. The main three elements emerging from the analysis are criminality, poverty and exploitation. As data suggests, Italy is the favorite destination of the Nigerian sexual exploitation market. In particular, Sicily plays a major role in the sexual exploitation ring involving Nigerian migrants, besides headquartering the Italian as well the Nigerian mafia. The agreement between Cosa Nostra (Sicilian Mafia) and the two organizations known as Black Axe and Eye (Nigerian mafia) represents the starting point for sexual…

Black European Inscriptions and the Challenge to Modern Essentialist Identities: The Case of Bernardine Evaristo’s Soul Tourists

2013

This essay shows how the London-born Anglo-Nigerian author Bernardine Evaristo contributes, with her Soul Tourists (2005), to deconstructing modern European nationalist and racially exclusivist models by means of anti-essentialist representational strategies. Centred around the voyage by car and across Europe which, in the late eighties, leads two black Britons, Stanley Williams and Jessie O’Donnell, from England to the Middle East, the novel becomes an imaginative vehicle through which Evaristo represents the black presence as intrinsic to Europe since the th century and foregrounds the substantial contribution of black and mixed-race men and women to the cultural development of Western …

Questioning the Canon and Re-Writing/Re-Righting the Female Colonized Subject: Mary Seacole’s Wonderful Adventures and George Bernard Shaw’s The Adve…

2021

Albeit different in terms of formal solutions and conception, Mary Seacole’s 'Wonderful Adventures' (1857) and G.B. Shaw’s 'The Adventures of the Black Girl in Her Search for God' (1932) share an oppositional aesthetics which, in both cases, helps undermine any prevailing representation of the colonial Other. Indeed, Seacole’s and Shaw’s works manipulate the trope of travel in such a way as to overcome traditional conceptions of the literary canon as well as hegemonic visions of subjectivities. In taking into consideration the innovative representation of the Black colonized woman as delineated in both works, the essay aims to show the way in which they present an anti-normative identity mo…

Radiative 2D Shocks, Super-Eddington Disks and Jets around Black Holes

2005

It is well known that rotating inviscid accretion flows with adequate injection parameters around black holes could form shock waves close to the black holes, after the flow passes through the outer sonic point and can be virtually stopped by the centrifugal force. Such shock waves in 2D accretion flows are examined by 2D radiation hydrodynamical calculations. We also examine super‐Eddington accretion disks with 15 ṀE around black holes, focusing on a small collimation degree of the jet and a large mass‐outflow rate observed in the X‐ray source SS 433.

Shock oscillation model for quasi-periodic oscillations in stellar mass and supermassive black holes

2007

We numerically examine centrifugally supported shock waves in 2D rotating accretion flows around a stellar-mass (10M_sun) and a supermassive (10^6M_sun) black holes over a wide range of input accretion rates of 10^7 >\dot M/\dot M_E>10^{-4}. The resultant 2D-shocks are unstable with time and the luminosities show quasi-periodic oscillations (QPOs) with modulations of a factor of 2-3 andwith periods of a tenth seconds to several hours, depending on the black hole masses. The shock oscillation model may explain the intermediate frequency QPOs with 1-10 Hz observed in the stellar-mass black hole candidates and also suggest the existence of QPOs with the period of hours in AGNs. When the accret…

Konsul’stvo Pol’ŝì v Odesì v 1918-1920 rr ta jogo arhìv

2017

General Consulate of the Republic of Poland established in Odessa in 2003 is the third Polish diplomatic mission in the Black Sea region of present — day Ukraine. The second Polish consulate, representing the reviving Polish statehood, functioned at the Black Sea between January 1919 and the beginning of February 1920, with almost a 5-month-long break, during the first Bolshevik occupation of Odessa. Zenon Belina Brzozowki was the consul in office during the period of January, 4, 1919 to March, 3, 1919 and then again since the end of August, (between April and August he stayed in Istanbul), in October and November, 1919 he was replaced by Stanisław Srokowski, a diplomat in the rank of I cla…

An Approach on the Hydrogen Absorption in Carbon Black after Gamma Irradiation

2013

In this work, different samples of an industrial carbon black are used to study the hydrogen intake from an over pres-surized atmosphere and its changes due to alteration of its level of crystallinity produced by ¿-irradiation. The monitor-ing of the hydrogen adsorption was made by means of thermogravimetric analysis and by measurements of some elec-trical parameters as the Seebeck coefficient. X-ray diffraction shows that the irradiation diminishes the level of crystal-line perfection. These results show interesting possibilities to use carbon black as cheap hydrogen absorbers.

A multi-analytical approach for the characterization of black crusts on the facade of an historical cathedral

2020

Abstract This study focuses on the characterization of black crusts collected from the Monza cathedral located in the homonymous city (N Italy), a hot spot from the point of view of the atmospheric pollution. Black crusts and substrate marble specimens were analyzed by a multi-analytical approach including X-ray Diffraction (XRD), Fourier Transform-Infrared spectroscopy (FT-IR), Stereomicroscopy (SM), Polarized Light Microscopy (PLM), High Resolution Scanning Electron Microscopy coupled with Energy Dispersive X-ray spectroscopy (HRSEM-EDX) and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP/MS). The characterization of the carbon fraction (organic carbon, OC, and element…
