Decolonial Thinking and Refugees’ Stories. The Queens of Syria Documentary (2014)
2019
As an important stimulus for the international mushrooming of artistic creativity in public spaces, counter narratives by displaced people are contributing to the reframing of the political and sociolinguistic contemporary framework, where migrant identities are fighting to gain a voice. A counter wave of audiovisual productions based on aesthetic discourse has emerged within territories that seem to be losing their humanity with respect to migration issues, and seem to publicly reinforce forms of spectacularisation. Against a backdrop of international political conflict, where migrants and dispossessed refugees are nameless and cannot speak, visual and performative arts have taken on a dec…
Soil microbial biomass carbon and fatty acid composition of earthworm Lumbricus rubellus after exposure to engineered nanoparticles
2014
none 6 no First Online: 14 October 2014 The aim of this work was to investigate the effect of engineered nanoparticles (NPs) on soil microbial biomass C (MBC) and on earthworm Lumbricus rubellus. An artificial soil was incubated for 4 weeks with earthworms fed with vegetable residues contaminated by NPs, consisting of Ag, Co, Ni and TiO2. After the treatments, soils were analysed for MBC and total and water soluble metal-NPs, whereas earthworms were purged for 28 days and then analysed for fatty acids (FAs) and total metal-NPs. Longitudinal sections of earthworms were investigated by environmental scanning electron microscopy (ESEM), equipped with energy-dispersive X-ray spectroscopy (EDS),…
Determination of molecular species of oil triacylglycerols by reversed-phase and chiral-phase high-performance liquid chromatography
1991
A method is described for the determination of molecular species of oil triacylglycerols. The method is based on the analytical separation of the enantiomericsn-1,2-andsn-2,3-diacylglycerols, derived from triacylglycerols, by high-performance liquid-chromatography (HPLC) on a chiral column containing N-(R)-1-(α-naphthyl)ethylaminocarbonyl-(S)-valinecarbonyl-(S)-valine as stationary phase. Model triacyl-glycerol molecules comprising three known fatty acids were isolated from peanut oil and cottonseed oil by a combination of argentation-TLC and reversed-phase HPLC and submitted to partial chemical deacylation. The derivedsn-1,2(2,3)-diacylglycerols were analyzed and fractionated as 3,5-dinitr…
XRF analysis to identify historical photographic processes: The case of some Interguglielmi Jr.’s images from the Palermo Municipal Archive
2017
Abstract In the early period, even though professional photographers worked with similar techniques and products, their artistic and commercial aims determined different choices and led them to follow different, often personal, recipes. For this reason, identification of the techniques through date and name of the photographer or through some visual features like colour, tonality and surface of the image layer, often needs further investigation to be proved. Chemical characterization, carried out in a non or micro destructive way, can be crucial to provide useful information about the original composition, degradation process, realization technique, in obtaining an indirect dating of the ph…
Associations of nutrition and body composition with cardiovascular disease risk factors in soldiers during a 6-month deployment
2020
Objectives This observational follow-up study investigated the associations of nutrition and body composition with cardiovascular disease (CVD) risk factors, including pro-inflammatory biomarkers, in soldiers during a 6-month deployment. Material and Methods Thirty-five male soldiers were assessed at months 0, 3 and 6, and their parameters, i.e., M±SD, were as follows: age 30.0±8.7 years, height 179±6 cm, and BMI 24.2±2.5 kg/m 2 . Three-day food diaries were used for monitoring macronutrient intake. Body composition was estimated using bioimpedance. Fasting blood samples for lipids and pro-inflammatory biomarkers were collected, and blood pressure measurements were performed. Results Carboh…
A new method for the in situ determination of phospholipids after thin-layer separation
1973
Abstract A very sensitive method has been devised for the in situ determination of phospholipids after thin-layer chromatographic separation, which enabled us to investigate the phospholipid content of erythrocytes and ATPase preparations. The phospholipid compositions of the ATPase preparations and of the erythrocytes are different, and the relative phospholipid compositions of the Na,K-ATPase preparations are also different, which indicates that Na,K- and Ca-ATPase seem to be different with regard to their phospholipid composition. An increase in temperature during the preparation procedure yields a Ca-ATPase preparation (II), which exhibits different kinetic properties and a different ph…
La hermenéutica cultural como herramienta estratégica de la investigación para el diseño
2017
Historicamente, la hermeneutica ha permitido conocer formas de apropiacion de mundos de vida y realidades diversas, hoy su uso se ha ampliado hacia areas relacionadas con el lenguaje y la cultura. La hermeneutica permite al disenador desde la investigacion estudiar no solo el lenguaje que puede y debe generar, sino a traves de ciertas estrategias y dispositivos de esta disciplina, conocer de manera mas profunda al consumidor o cliente al que se le realiza el diseno, con el objeto de que el objeto disenado establezca un vinculo identitario entre este objeto con su sujeto.
Animales, teorías feministas posmodernas y prácticas artísticas.
2019
Este artículo pretende mostrar cómo algunas teorías feministas posmodernas como el ecofeminismo y el posthumanismo, de autoras como Françoise d'Eaubonne, Alicia Puleo, Donna Haraway o Rosi Baridotti han contribuido a la crítica contra las prácticas androcéntricas basadas en el dominio sistémico de devastación y explotación del otro/a/os, perpetuando la jerarquía y autoridad del hombre. Frente a ello estas autoras han propuesto un nuevo modelo de relación orgánica y de convivencia entre cultura y naturaleza, capaz de superar los modelos binarios, inspirado en el respeto a la diversidad de sexos y especies.Estos principios se hayan, así mismo, en las prácticas artísticas de algunas autoras c…

European Lifelong Guidance Policy Network representatives’ conceptions of the role of information and communication technologies related to national …
2015
This article reports findings from a phenomenographic investigation into European Lifelong Guidance Policy Network representatives’ conceptions of the role of information and communication technologies (ICT) related to national lifelong guidance policies. The role of ICT in relation to national lifelong guidance policies was conceived as (1) unexploited, (2) emerging, (3) acknowledged but fragmented, and (4) strategic. The hierarchical structure of the findings may serve as a tool to enable policy makers and other stakeholders to deepen their understanding of critical aspects that may have an important role in relation to further developments and the successful implementation of existing an…
