The powers of masculinization in humanitarian storytelling: the case of the surgeon María Gómez Álvarez in the Varsovia Hospital (Toulouse, 1944–1950)
2020
This contribution is focused on analysing the power of 'masculinization' through which traditional humanitarian storytelling has been shaped. Strongly marked by a patriarchal vision, humanitarian accounts have traditionally hidden the work of women while stressing that performed by men, who appeared represented as true protagonists and, even, as heroes. In particular, this article analyses the professional career of a Spanish female surgeon named Maria Gomez (1914-1975) between 1944 and 1950, when she worked in a small charitable hospital based in Toulouse (France) for improving the health-care conditions of Spanish Republican refugees. Known as Hospital Varsovia or as Walter B. Cannon Memo…
Improvement of high modulus asphalt mixtures with average quality aggregate and bitumen by application of polymeric additives
2018
Abstract The paper deals with the development of asphalt mixtures for high performing binder and base courses, modified with both commercial and waste polymeric additives, via dry process. The focus was on the mix design of high performing mixtures making use of average quality aggregate and average penetration grade bitumen (as locally available) instead of the usually required high quality components, manly very hard bitumen, thus aiming to improve the reference mixture as made possible by suitable polymers. Mixtures were subjected not only to conventional tests for mix design purposes, but also to advanced tests for performance evaluation such as rutting resistance and fatigue resistance…
Adding the Mureş River Basin (Transylvania, Romania) to the List of Hotspots with High Contamination with Pharmaceuticals
2020
Background: The Mureș River Basin is a long-term heavily polluted watershed, in a situation of climate changes with increasing water flow and related decreasing dilution capacity. Here, a mixture of emerging pollutants such as pharmaceuticals were targeted to reveal potential risks regarding the natural lotic ecosystems. Due to the continuous discharge into the environment, pharmaceuticals are gaining persistent organic pollutant characteristics and are considered emerging pollutants. Based on the hazard quotient, this research highlights the dangerous concentrations of carbamazepine, ibuprofen, furosemide, and enalapril in river water. Results: High levels of four pharmaceutical compounds …
An optical classification tool for global lake waters
2017
Shallow and deep lakes receive and recycle organic and inorganic substances from within the confines of these lakes, their watershed and beyond. Hence, a large range in absorption and scattering and extreme differences in optical variability can be found between and within global lakes. This poses a challenge for atmospheric correction and bio-optical algorithms applied to optical remote sensing for water quality monitoring applications. To optimize these applications for the wide variety of lake optical conditions, we adapted a spectral classification scheme based on the concept of optical water types. The optical water types were defined through a cluster analysis of in situ hyperspectral…
Well‐being in European regions: Does government quality matter?
2020
This paper constructs a composite indicator of well‐being for 168 European regions with data from 10 well‐being domains. Regions are then ranked according to their respective levels of well‐being. The ranking reveals notable differences across European regions, which follow a marked spatial pattern. As a second contribution, the paper analyses the impact of the quality of government on well‐being. Results show a positive association robust to several specifications and scenarios. Moreover, the effects of quality of government on individual well‐being dimensions are identified, finding positive links with education, jobs, income, safety civic engagement, access to services, housing and commu…
The impact of health status and human capital formation on regional performance: Empirical evidence
2020
The purpose of this paper is to analyse the impact of health on growth, assuming that it is a fundamental component of the human capital of a region along with education. Various measures of population health status are used, together with a health index generated by principal component analysis. Potential endogeneity between health and growth is controlled for using instrumental variable regressions and dynamic panel data. The results show a positive effect of a change in health status on regional output and a negative effect of proxy variables for health limitations on regional performance. This corroborates the importance of investing in health along with education with the aim of improv…
Party Positions on Differentiated European Integration in the Nordic Countries: Growing Together, Growing Apart?
2020
The Nordic countries constitute an interesting laboratory for the study of differentiated European Integration. Even though Denmark, Finland, Iceland, Norway, and Sweden share some historical, cultural, socio-economic and political characteristics, all those countries have ultimately opted for a different kind of relationship with the EU. Whereas Finland, a member of the Eurozone since its inception in 1999, has been considered to be part of the Union’s ‘inner core’ for quite some time, Iceland and Norway, in contrast, have opted to remain outside the EU albeit closely associated via the European Economic Area Agreement. The variation of relationships has also been reflected in Nordic parti…
Developing an economically advantageous wind forecasting method for electricity market design with a 15-minute imbalance settlement period
2019
According to legal framework developed by European Commission all EU Member States shall employ 15minute time resolution for imbalance settlement no later than 18th of December 2020 (or 1st of January 2025 in case of derogation). For intermittent energy sources that are traditionally associated with less precise generation forecasts this might result in considerable increase in imbalance costs. This presents a unique challenge for wind power station operators as there is lack of adequate forecasting tools supporting 15-minute time-resolution. The objective of this paper is to test and provide comparative analysis of alternative data interpolation methods in order to determine approach assoc…
Active heave compensation of floating wind turbine installation using a catamaran construction vessel
2021
Abstract The application of floating wind turbines is limited by the high cost that increases with the water depth. Offshore installation and maintenance continue to consume a high percentage of the project budget. To improve the installation efficiency of the floating offshore wind turbine, a novel concept is proposed by the SFI MOVE project. Several wind turbine superstructure components are preassembled onshore and carried to the installation site by a catamaran construction vessel. Each assembly can then be installed using only one lift, and the concept is less sensitive to weather conditions. In this paper, a control algorithm of the proposed hydraulic active heave compensator system i…
Experimental characterization of a novel configuration of thermoelectric refrigerator with integrated finned heat pipes
2021
Abstract Thermoelectric refrigerating systems (TER) are environment-friendly technologies. They have several advantages such as low maintenance costs, are less cumbersome and long lifetime. However, these systems have low coefficient of performance and are limited in achieving low temperature levels. This study investigates a new configuration of TE refrigerator employing a novel arrangement of heat sinks with integrated flat and finned heat pipes. A mathematical model is firstly developed to predict transient temperatures and cooling limit time. An experimental characterization is then performed and it includes optimization of energy consumption, cooling time, temperature levels and TE ref…
