Perdere il senno e darsi la morte. Due casi singolari di punizione divina nelle Storie di Erodoto (V 85; VI, 75)
2016
Scopo di questo paper è l’analisi dei temi della follia e del suicidio nella struttura narrativa di Erodoto. I due episodi esaminati sono: a) il racconto della pazzia che colpì gli Ateniesi, che avevano tentato invano di sottrarre agli Egineti le sacre statue di Damia e Auxesia; b) la storia dei disaccordi tra i due re spartani Demarato e Cleomene e il loro tragico esito. Questi due episodi sono profondamente interconnessi: attraverso i rimandi interni, suggeriti dalle scelte linguistiche dello storico, noi vogliamo infine riflettere sul modello causale erodoteo. The aim of this paper is the analysis of the themes of madness and suicide in the narrative structure of Herodotus. Two episodes …
Perfil sociodemográfico asociado a la ideación suicida de las personas transexuales
2020
Las personas transexuales experimentan tasas extremadamente altas de conductas suicidas. Sin embargo, aunque la ideación suicida se considera un precursor importante de intento de suicidio, se ha prestado poca atención a esta problemática y al perfil sociodemográfico de este colectivo. Así, nos proponemos identificar la prevalencia de ideación suicida en una muestra de pacientes transexuales y explorar su perfil sociodemográfico. Para ello, se recogió información sociodemográfica de 172 transexuales (58.7% mujeres transexuales, 41.3% hombres transexuales) de entre 18 y 61 años que acudieron a la Unidad de Trastornos de Identidad de Género del Complejo Hospitalario Carlos Haya. Los resultado…

Taxonomy of homicides of women in intimate partner relationships
2018
RESUMEN La prevención de la violencia contra la pareja supone un problema que ha suscitado gran interés a nivel internacional. El homicidio de pareja es el exponente más grave, aunque su prevalencia sea baja y su etiología compleja. Este trabajo revisa brevemente la descripción del problema desde la perspectiva de género y la existencia de asimetría, la perspectiva de la violencia y su descripción de factores de riesgo diferenciales y el modelo ecológico que relaciona variables personales, contextuales y comunitarias, presentando una propuesta más integradora. Se describen los estudios que analizan y comparan perfiles de homicidas, así como la situación en materia de evaluación del riesgo, …
Efficiency of QuEChERS approach for determining 52 pesticide residues in honey and honey bees
2016
A comparison between QuEChERS and other pesticide extraction procedures for honey and honey bee matrices is discussed. Honey bee matrix was extracted by solvent based procedure whereas solid phase extraction was the protocol for the honey matrix. The citrate buffered QuEChERS method was used for both matrices. The methods were evaluated regarding cost (equipment and reagents), time, accuracy, precision, sensitivity and versatility. The results proved that the QuEChERS protocol was the most efficient method for the extraction of the selected pesticides in both matrices. QuEChERS is the most economical and less time-consuming procedure.SPE and solvent-based extraction procedures show equivale…
Comparing the effects of thermal and non-thermal technologies on pomegranate juice quality: A review.
2019
The consumption of pomegranate juice (PJ) has increased substantially since scientific literature reported its therapeutic benefits that are attributable to antioxidant, antimicrobial, anti-carcinogenic, and anti- inflammatory properties. The growing consumer demands for fresh and high-quality food products have led to the interest in non- thermal technologies for preservation of fruit juices. Although thermal pasteurization is the most widely used preservation technology, it has adverse effects on the nutritional and sensory quality of juices. Conversely, non- thermal technologies are suitable alternatives for preservation and without negative effects on the quality. However, there is limi…
Green tea extract assisted low-temperature pasteurization to inactivate enteric viruses in juices.
2020
The current popularity of minimally processed foods is an opportunity for natural antimicrobial agents to be combined with mild heat treatments to act synergistically in reducing viral foodborne pathogens. Viral inactivation by heat-treatments (at 25, 40, 50 and 63 °C for 30 min) combined with aged green tea extract (aged-GTE) was initially evaluated in phosphate buffered saline (PBS) against murine norovirus (MNV-1) and hepatitis A virus (HAV) by cell culture, and against human norovirus by in situ capture RT-qPCR. The combination of aged-GTE and heat treatment at 50 °C for 30 min exerted strong antiviral activity, reducing by more than 5 log MNV-1 infectivity in PBS. Heating at 40 °C for …
Ecological aspects of plants inhabiting Mediterranean cliffs. Challenges and prospects of life in vertical environments
2021
[ES] Esta tesis investiga las oportunidades, desafíos y limitaciones para la investigación en el campo de la ecología vegetal, en el contexto de los acantilados mediterráneos. En concreto, las especies casmofiticas, cuyos hábitats naturales se caracterizan por su acusada pendiente. Las laderas de las montañas de piedra caliza en la proximidad del mar, en la parte central y occidental del área mediterránea se consideran objetos de estudio. Los estudios se llevaron a cabo en los cinturones costeros de montaña de las costas del noroeste de Sicilia y la costa diánica en la Comunidad Valenciana. El primer capítulo, titulado "The complexity of environmental factors: cliff microclimate", investiga…
Associations between parental rules, style of communication and children's screen time
2015
Background Research suggests an inverse association between parental rules and screen time in pre-adolescents, and that parents’ style of communication with their children is related to the children’s time spent watching TV. The aims of this study were to examine associations of parental rules and parental style of communication with children’s screen time and perceived excessive screen time in five European countries. Methods UP4FUN was a multi-centre, cluster randomised controlled trial with pre- and post-test measurements in each of five countries; Belgium, Germany, Greece, Hungary and Norway. Questionnaires were completed by the children at school and the parent questionnaire was brough…
Analytical tools used for the identification and quantification of pectin extracted from plant food matrices, wastes and by-products: A review
2018
Pectin is the methylated ester of polygalacturonic acid and has a wide range of applications. It can be used in food and animal feed as well as in pharmaceutical and cosmetic products. Pectin is traditionally used as a gelling agent in fruit-based products, as a stabilizer in some fruit juices and milk drinks and fruit filling for bakery and confectionary products, but their potential applications differ according to their chemical composition. Therefore, at this stage of development, it is of a great importance to find fast, reliable methods to not only identify and quantify pectin, but also to determine its chemical structure and composition when it is extracted from plant matrices, waste…
