The influence of internal degrees of freedom on the unimolecular decay of the molecule–cluster compound Au8+CH3OH

2002

Time-resolved photodissociation measurements of the sequential reaction Au8+CH3OH→Au8+→Au7+ and the direct reaction Au8+→Au7+ have been performed for several excitation energies. The production rates and yields of the final state Au7+ in the sequential process are strongly influenced by the excitation energy deposited into the evaporated methanol molecule during the initial fragmentation step. Both the rate constants and yields can be fitted with a single parameter, the cluster–methanol binding energy.

Selection of optimal narrowband multispectral images for face recognition

2015

Face recognition systems based on ’conventional’ images have reached a significant level of maturity with some practical successes. However, their performance may degrade under poor and/or changing illumination. Multispectral imagery represents a viable alternative to conventional imaging in the search for a robust and practical identification system. Multi- spectral imaging (MI) can be defined as a ’collection of several monochrome images of the same scene, each of them taken with additional receptors sensitive to other frequencies of the visible light or to frequencies beyond the visible light like the infrared region of electro- magnetic continuum. Each image is referred to as a band or …

Influence of Geometrical Parameters, Wall Angle and Part Shape on Thickness Reduction of Single Point Incremental Forming

2014

Abstract The aim of this paper is to study the thickness reduction during the whole single point incremental forming process. The experimental setup is realized in such a way that the blank sheet is in the vertical position and forming is done using an anthropomorphic robot with six degrees of freedom. The vertical positioning of the blank sheet allows the on-line visualization using an optical measuring system of the major and minor strains and of the thickness reduction. The wall angle varied between values of 45 0 , 55 0 and 65 0 respectively. The logarithmic major strain and minor strains and logarithmic thickness reduction were analyzed in order to allow a comparison with values obtain…

Energy-weighted M1 sum rule with explicit δ degrees of freedom

1985

Abstract The influence of Δ degrees of freedom on the energy-weighted M1 sum rule is investigated and applied to 2 H and 4 He. Using π- and ρ-exchange potentials a reduction of the potential contribution of the order of 50% is obtained. The absolute value of the sum rule is strongly dependent on the short-range behaviour of the nuclear wave function. Furthermore, the contribution of c.m. effects is evaluated and found to be of the order of 5–10%.

Gestión de mano de obra en la empresa pública: el caso de RENFE

2008

Los cambios en las prácticas de gestión de mano de obra que se están aplicando en Renfe en las últimas décadas han conllevado una reducción drástica de la plantilla (flexibilidad en la salida), y una mayor disponibilidad laboral de los que han quedado (flexibilidad funcional). Dichos cambios guardan relación con la orientación privatizadora de la economía que impone un cuestionamiento del modelo de transporte ferroviario existente hasta fechas recientes. Asimismo, están condicionados por el hecho de ser una empresa pública (financiación presupuestaria, politización,...). El objetivo básico de las prácticas de gestión de mano de obra aplicadas en Renfe es la reducción de los costes laborales…

Limits in medical care and social relief during the Spanish Civil War in a rear-guard city: the inclusa of the provincial hospital of Valencia.

2016

Due to its geostrategic condition during the Spanish Civil War, Valencia became one of the Republican cities welcoming more refugees, including many children. In this scenario of demographic and health crisis, the town had to restructure the assistance network in order to accommodate thousands of displaced children, who often had their relatives in faraway places. The paper focuses in the progressive rehabilitation undertaken by the Inclusa of Valencia, which was the provincial foundling hospital. This included deep changes both in its operation and in the admission criteria, particularly following the transfer of the Inclusa of Madrid to Valencia. The resulting overcrowding encouraged the …

Vulnerability in Migration: The Applicability of European Recommendations, International Reports and Guidelines to the Italian System of Reception an…

2018

The European Parliament’s Report focuses on the integration processes for a particular category of refugees, considered as belonging to “vulnerable groups”, namely women seeking international protection and female refugees. Women seeking international protection or refugees, in fact, are bearers of demands and needs which, in part, are specific to all those people who, often forced to abruptly abandon their countries of origin, seek protection in host countries, bringing with themselves a heavy burden of persecution, war, violence and poverty. The humanitarian response along the routes of the eastern Mediterranean and the western Balkans has set as a priority the introduction of measures to…

AYLAN E COLONIA. DALLA GUERRA AI MIGRANTI AL RESPINGIMENTO DEI REFUGEES

2017

This contribution aims to shed light on the specific mechanism of migrant categorization implemented by the so-called «Hotspot approach», which was launched by the EU Agenda on Migration in May 2015. This approach is here envisaged as a response to the current changes in the composition of migration towards Europe. Provisions contained in EU and Italian policy documents are compared with concrete practices enacted on the ground by investigating two case studies: the initial opening of the Hotspot at Milo, in Trapani, and the first months of functioning of the Hotspot on Lampedusa. The empirical research covers the period between the last months of 2015 and the beginning of 2016. The short-t…

Epidemiological characteristics of COVID-19 cases in non-Italian nationals in Sicily: identifying vulnerable groups in the context of the COVID-19 pa…

2022

As in other parts of the world, undocumented migrants in Italy suffer worse health status due to their immigration enforcement situation and other vulnerabilities such as precarious illegal jobs, exploitation and abuse or barriers to higher education, with higher prevalence of chronic noncommunicable diseases. The COVID-19 pandemic, as other pandemics, has not affected everyone equally. The undocumented was one of the most affected groups with regard to hospitalization rates and mortality worldwide. Sicily is one of the gates of entrance to Europe for migrants and asylum seekers from Africa and Asia. Herein, we described the epidemiological characteristics of COVID-19 cases in Sicily to com…
