Novel solutions for closed-loop Reverse Electrodialysis: thermodynamic characterisation and perspective analysis
2019
Abstract Closed-loop Reverse Electrodialysis is a novel technology to directly convert low-grade heat into electricity. It consists of a reverse electrodialysis (RED) unit where electricity is produced exploiting the salinity gradient between two salt-water solutions, coupled with a regeneration unit where waste-heat is used to treat the solutions exiting from the RED unit and restore their initial composition. One of the most important advantages of closed-loop systems compared to the open systems is the possibility to select ad-hoc salt solutions to achieve high efficiencies. Therefore, the properties of the salt solutions are essential to assess the performance of the energy generation a…
Evapotranspiration from an Olive Orchard using Remote Sensing-Based Dual Crop Coefficient Approach
2013
A remote sensing-based approach to estimate actual evapotranspiration (ET) was tested in an area covered by olive trees and characterized by Mediterranean climate. The methodology is a modified version of the standard FAO-56 dual crop coefficient procedure, in which the crop potential transpiration, T p, is obtained by directly applying the Penman-Monteith (PM) equation with actual canopy characteristics (i.e., leaf area index, albedo and canopy height) derived from optical remote sensing data. Due to the minimum requirement of in-situ ancillary inputs, the methodology is suitable also for applications on large areas where the use of tabled crop coefficient values become problematic, due to…
Los deberes de los administradores en situación de insolvencia inminente en la propuesta de Directiva sobre marcos de reestructuración.
2019
La última versión de la Propuesta de Directiva sobre marcos de reestructuración preventiva de 28 de marzo de 2019, ha recuperado en su art. 19 la obligación de los administradores de tomar en consideración el interés de los acreedores en las situaciones de insolvencia inminente. Dicha obligación supone una modulación del contenido del interés social en dicha situación, el cual junto al interés de los socios, comprende también el interés de los acreedores. Esta configuración compleja del interés social obliga por tanto a analizar cuál es el concreto contenido de los deberes de los administradores en dicha situación de insolvencia inminente, habida cuenta de su orientación hacia la consecució…
Characterization of Intertidal Macrofaunal Communities of Two Sandy Beaches under Different Anthropogenic Pressures
2022
The macrofauna in the intertidal zone of sandy beaches provides the trophic connectivity between land and sea, by linking microbiome, meiofauna, and megafauna, representing a food source for several terrestrial animals, including shorebirds and mammals. However, the macrozoobenthos in urbanised beaches is subjected to intense disturbances, such as breakwater barriers and tourism, which limit or impede the energy transfer from the marine to the terrestrial habitats. Because the information about diversity and abundance of the macrozoobenthos of the intertidal zone on the Mediterranean sandy coasts is scant, the main objective of this study is to increase the knowledge on the macrofauna livin…
Effect of fall direction on the lower hip fracture risk in athletes with different loading histories : A finite element modeling study in multiple si…
2022
Physical loading makes bones stronger through structural adaptation. Finding effective modes of exercise to improve proximal femur strength has the potential to decrease hip fracture risk. Previous proximal femur finite element (FE) modeling studies have indicated that the loading history comprising impact exercises is associated with substantially higher fracture load. However, those results were limited only to one specified fall direction. It remains thus unclear whether exercise-induced higher fracture load depends on the fall direction. To address this, using magnetic resonance images of proximal femora from 91 female athletes (mean age 24.7 years with >8 years competitive career) and …
Changing pattern and etiology of maxillofacial fractures during the civil uprising in Western Libya
2018
Background The purpose of the present study was to evaluate changing pattern in characteristics of maxillofacial fractures and concomitant injuries in Western Libya During revolution and to assess the association between mechanism of injury and fracture patterns. Material and Methods A retrospective review of medical records and radiographs of 187 patients treated for maxillofacial fractures from January 2010 to December 2012 was performed, there were 326 fractures in 187 patients. Results The male: female ratio was 6:1. Most fractures occurred in patients aged 11 to 40 years, and few injuries occurred in patients aged > 50 years. Most fractures occurred from motor vehicle accidents, and ot…
A scale on beliefs about children's adjustment in same-sex families: reliability and validity.
2012
In this study, we developed a new instrument named Scale Beliefs about Children's Adjustment on Same-Sex Families (SBCASSF). The scale was developed to assess of the adults' beliefs about negative impacts on children who are raised by same-sex parents. An initial pool of 95 items was generated by the authors based on a review of the literature on homophobia and feedback from several focus groups. Research findings, based on a sample of 212 university students (mean age 22 years, SD = 8.28), supported the reliability and validity of the scale. The final versions of the SBCASSF included items reflecting the following two factors: individual opposition (α = .87) and normative opposition (α = .…
Tap water consumers differ from non-consumers in chlorine flavor acceptability but not sensitivity
2010
International audience; Unpleasant taste and especially chlorine flavor is one of the most common reasons advocated for choosing tap water alternatives as drinking water. As a consequence, the putative link between sensitivity to chlorine flavor and tap water consumption is an issue in drinking water habits studies. In the present study, we set out to examine such a link following a strategy in which we measured chlorine flavor perception at threshold and supra-threshold level for two groups of participants selected on their drinking water consumption habits. The first group included exclusive tap water consumers and the second group included exclusive bottled water consumers. In a first ex…
Impact of psychological risk factors on disaster rescue operations: the case of Italian volunteers.
2007
This paper reports on research into the characteristics of emergency rescue workers, with a focus on psychological distress. We present the results of a study of volunteers from the Italian national civil protection programme. A questionnaire was administered to 2,576 subjects from all over Italy. Most respondents were men, mostly unemployed, whose average level of education was higher than that among most Italian volunteers. Many were poorly endowed with basic skills, with large differences according to geography. Many expected to convert their volunteer activities into permanent jobs. Using this data, we employed a logistical regression model to analyse the risk of low, moderate and sever…
Current status and needs for changes in critical care training: the voice of the young cardiologists
2020
Abstract Aims The implementation of the 2013 European Society of Cardiology (ESC) Core Curriculum guidelines for acute cardiovascular care (acc) training among European countries is unknown. We aimed to evaluate the current status of acc training among cardiology trainees and young cardiologists (<40 years) from ESC countries. Methods and results The survey (March–July 2019) asked about details of cardiology training, self-confidence in acc technical and non-technical skills, access to training opportunities, and needs for further training in the field. Overall 614 young doctors, 31 (26–43) years old, 55% males were surveyed. Place and duration of acc training differed between countr…
