Geography of Emotions Across the Black Mediterranean: Oral Memories and Dissonant Heritages of Slavery and the Colonial Past
2019
AbstractThis contribution is dedicated to analysing oral memories about the Black Mediterranean through interviews with people from or culturally linked to the Horn of Africa. The aim is to consider how the interviewees make use of archives to voice their feelings about the past and present in Africa and Europe. I introduce the concept of a “geography of emotions” as a set of different perceptions of Europe and its past. The mobilization of these memories in new interpretative perspectives is part of a dissonant heritage which is actively working inside the European borders in order to produce new cultural identities, to reiterate forms of belonging to black diasporic communities, and to in…
Electrodeposition of CeO2 and Co-Doped CeO2 Nanotubes by Cyclic Anodization in Porous Alumina Membranes
2013
An anodic electrodeposition process is proposed to prepare CeO2 and Co-doped CeO2 nanotubes. Anodic alumina membrane is used as template and linear sweep voltammetry is employed to allow the formation of nanotubes without alumina dissolution. SEM micrographs showed large arrays of well defined and aligned NTs, which resulted to be crystalline soon after deposition according to XRD diffraction patterns and Raman Spectroscopy.
Funnel plots and choropleth maps in cancer risk communication: a comparison of tools for disseminating population-based incidence data to stakeholders
2017
Background Population-based cancer registries provide epidemiological cancer information, but the indicators are often too complex to be interpreted by local authorities and communities, due to numeracy and literacy limitations. The aim of this paper is to compare the commonly used visual formats to funnel plots to enable local public health authorities and communities to access valid and understandable cancer incidence data obtained at the municipal level. Methods A funnel plot representation of standardised incidence ratio (SIR) was generated for the 82 municipalities of the Palermo Province with the 2003–2011 data from the Palermo Province Cancer Registry (Sicily, Italy). The properties …
Keyhole limpet haemocyanin (KLH): Purification of intact KLH1 through selective dissociation of KLH2
1995
Abstract Keyhole limpet haemocyanin (KLH) from almost all newly captive animals contains a mixture of KLH1 and KLH2. We show that the dissociation of KLH2 can be produced during EM specimen preparation by the negative staining-carbon film (NS-CF) procedure and in solution by ammonium molybdate-PEG solutions at slightly acidic pHs. The KLH2 multidecamers split apart in the pH range 7.5-6.5 and in the pH range 6.5-6.0 the individual decamers break open and start to dissociate. At pH 5.9 the dissociation of KLH2 yields predominantly a mixture of single subunits and what appear to be subunit dimers. Over the pH range 7.0-5.7 the KLH1 didecamer remains stable. Separation of intact KLH1, in the f…
Challenging Unequal Gendered Conventions in Heterosexual Relationship Contexts through Affective Dissonance
2019
In Nordic countries, intimate relationships are routinely compared against ideals of gender equality, even though equality is not always achieved in everyday life. In this article, we analyse interviews with women that lived in unconventional relationships: mid- to later-life women in relationships with younger men, and bisexual women who have had relationships with people of different genders. The women’s expectations of equality and reciprocity in heterosexual relationships collided with the lived reality of inequalities, causing affective dissonance. We identify three strategies that women use to deal with this affective dissonance. In the first strategy, unequal relationship patterns ar…
Electrochemical response of ferrocenium filled calix[4]arene capsules in solution and immobilized on gold
2008
Abstract Hydrogen-bonded dimers of tetra-urea calix[4]arenes are able to include ferrocenium ions as a guest. Heterodimeric capsules are exclusively formed in 1:1 mixtures of tetra-arylurea calix[4]arene 1 with tetra-tosylurea calix[4]arene 2. Sulfide groups attached via spacers on the urea rim of 1 allow their binding to metal surfaces rendering simultaneously their dissociation more difficult. Thus, the electrochemical response of encapsulated ferrocenium could be studied in a self-assembled monolayer (SAM) in addition to the solution electrochemistry with cyclic voltammetry. The stability of the electrochemically active monolayers was tested after a heat treatment (225 °C for 30 min in N…
Laser depassivation of a channel flow double-electrode: A new technique in repassivation studies
1993
Abstract A powerful tool for distinguishing between the different electrochemical steps involved during a depassivation-repassivation sequence was developed by combining the pulsed laser depassivation technique with an hydrodynamic electrochemical method: the channel flow double-electrode (CFDE). This experiment consisted of transporting the chemical species (Fe 2+ ) released by a depassivated iron electrode to a collecting electrode where these species were oxidized. A qualitative idea of the relative contribution of the anodic dissolution to the repassivation behavior was obtained. For a passive iron in acidic solution it was found that about 15% of the total charge is related to anodic d…
UV laser induced photolysis of glycolic acid isolated in argon matrices
2021
The photochemistry of matrix-isolated glycolic acid, induced by UV light, was studied by FTIR spectroscopy and B3LYPD3/6-311++G(3df,3pd) calculations. Several decomposition pathways were found to take place upon 212 nm and 226 nm wavelengths irradiation. A number of complexes formed between photoproducts were identified, among them those of formaldehyde with water, carbon monoxide and carbon dioxide as well as the H2O-CO complexes. The structure and spectroscopic assignment of the photoproducts were made comparing the experimental results with the theoretical predictions and available literature data. The observed formation of different complexes indicates various pathways for their formati…
Revisió sistemàtica dels tractaments per al trastorn d'identitat dissociatiu
2015
La finalitat d'aquesta revisió sistemàtica va ser determinar l'eficàcia dels mètodes terapèutics per al Trastorn d'Identitat Dissociatiu (DID), en què es diferencia entre tractament psicoterapèutic i farmacològic, així com el tractament per a pacients amb comorbilitat. D'un total de 1.209 referències obtingudes a la base de dades PsycInfo, s'hi seleccionaren 15 estudis a partir dels criteris de selecció establerts prèviament. Un dels estudis s'ha obtingut a la base de dades Web of Science. Els criteris seguits per seleccionar els articles són aquells amb pacients adults diagnosticats de DID que rebien alguna o ambdues modalitats terapèutiques esmentades més amunt, i foren rebutjats aquells …
Thermodynamics of computation and linear stability limits of superfluid refrigeration of a model computing array
2019
We analyze the stability of the temperature profile of an array of computing nanodevices refrigerated by flowing superfluid helium, under variations in temperature, computing rate, and barycentric velocity of helium. It turns out that if the variation in dissipated energy per bit with respect to temperature variations is higher than some critical values, proportional to the effective thermal conductivity of the array, then the steady-state temperature profiles become unstable and refrigeration efficiency is lost. Furthermore, a restriction on the maximum rate of variation in the local computation rate is found.
