Did the Finnish depression of the early 1990s have a silver lining? : The effect of unemployment on long-term physical activity
2022
This paper studies the impact of long-term unemployment on physical activity. We examined the effects 6 and 15 years following a severe business cycle downturn in Finland over the period 1991–1994. The study sample comprised residents of Northern Finland. The unemployed individuals were 23–26 years old during the downturn. Physical activity, measured by MET minutes and meeting WHO guidelines, was higher 15 years later among those people who experienced the longest periods of unemployment in 1991–1994. Physical activity was somewhat lower among people with relatively shorter periods of unemployment. peerReviewed
Dissolution and hydrolysis of fibre sludge using hydroxyalkylimidazolium hydrogensulphate ionic liquids
2014
Abstract The dissolution and hydrolysis of wet fibre sludge in ionic liquids (ILs) with different reaction conditions are performed in this study. Novel types of hydroxyalkylimidazolium hydrogensulphate ILs, [glymim]HSO 4 , [hemim]HSO 4 and [hpmim]HSO 4 , are especially designed and aimed to combine the dissolution and hydrolysis of wet fibre sludge in a one-step pretreatment. The results were obtained based on the analysis of total reducing sugars (TRS) with the DNS method. The dissolution and hydrolysis of fresh wild horse chestnut fruit ( Aesculus hippocastanum ) with the same ILs were also carried out as a comparison reference. Since fibre sludge is cellulose based and horse chestnut fr…
Building Bridges for Innovation in Ageing: Synergies between Action Groups of the EIP on AHA.
2017
The Strategic Implementation Plan of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) proposed six Action Groups. After almost three years of activity, many achievements have been obtained through commitments or collaborative work of the Action Groups. However, they have often worked in silos and, consequently, synergies between Action Groups have been proposed to strengthen the triple win of the EIP on AHA. The paper presents the methodology and current status of the Task Force on EIP on AHA synergies. Synergies are in line with the Action Groups' new Renovated Action Plan (2016-2018) to ensure that their future objectives are coherent and fully connected. The …
Algunas reflexiones sobre el alcoholismo femenino
2005
En el presente trabajo se pretende interesar al lector en el análisis del fenómeno del alcoholismo femenino. Se tratan diversos temas como el contexto en el que se socializan las mujeres, teniendo en cuenta los cambios acaecidos en la familia como institución y el rol de la mujer en la sociedad. Otra cuestión con referencia a ese contexto es la prevalencia del consumo de alcohol en el colectivo de mujeres en España y las nuevas tendencias de dicho consumo. Se revisan brevemente los diferentes enfoques teóricos que enmarcan la comprensión e interpretación del alcoholismo, incidiendo en los aspectos de la desviación social y el control social. Para finalizar, algunas consideraciones sobre la …
A Combination of Visible-Light Organophotoredox Catalysis and Asymmetric Organocatalysis for the Enantioselective Mannich Reaction of Dihydroquinoxal…
2019
[EN] An enantioselective photooxidative Mannich reaction of dihydroquinoxalinones with ketones by the merger of organophotoredox and asymmetric organocatalysis is described. This protocol features very mild reaction conditions using simple and cheap catalysts (Eosin Y and (S)-Proline) for the synthesis of chiral quinoxaline derivatives with good to high yields (up to 94%) and excellent enantioselectivities (up to 99% ee).
Photoelectrochemical characterization of anatase-rutile mixed TiO2 nanosponges
2016
This work studies the influence of using hydrodynamic conditions during anodization on the morphology and electrochemical properties of anatase/rutile mixed TiO2 nanotubes (Reynolds number, Re = 0) and nanosponges (Re > 0). To this purpose different techniques were used, such as: microscopy techniques (Field-Emission Scanning Electron Microscope, FE-SEM, and Confocal Laser-Raman Spectroscopy), Electrochemical Impedance Spectroscopy (EIS), Mott Schottky (MS) analysis and photoelectrochemical water splitting tests. This investigation demonstrates that the morphology of TiO2 nanostructures may be greatly affected due to the hydrodynamic conditions and it can be adjusted in order to increase th…
Effect of Reynolds number and lithium cation insertion on titanium anodization
2016
This work studies the influence of using hydrodynamic conditions (Reynolds number, Re = 0 to Re = 600) during Ti anodization and Li+ intercalation on anatase TiO2 nanotubes. The synthesized photocatalysts were characterized by using Field Emission Scanning Electron Microscope (FE-SEM), Raman Confocal Laser Microscopy, Electrochemical Impedance Spectroscopy (EIS), Mott-Schottky analysis (M-S), photoelectrochemical hydrogen production and resistance to photocorrosion tests. The obtained results showed that the conductivity of the NTs increases with Li+ intercalation and Re. The latter is due to the fact that the hydrodynamic conditions eliminate part of the initiation layer formed over the tu…
The use of equine K4b2 during incremental field exercise tests in driven Standardbred trotters: a preliminary study
2011
The equine K4b2 system is well tolerated by horses and allows O2 and CO2 measurements in field conditions up to maximal workload. The relationship between maximal oxygen consumption (VO2max) and maximal aerobic speed (MAS) still needs to be established.
Exploiting historical rainfall and landslide data in a spatial database for the derivation of critical rainfall thresholds
2017
Critical rainfall thresholds for landslides are powerful tools for preventing landslide hazard. The thresholds are commonly estimated empirically starting from rainfall events that triggered landslides in the past. The creation of the appropriate rainfall–landslide database is one of the main efforts in this approach. In fact, an accurate agreement between the landslide and rainfall information, in terms of location and timing, is essential in order to correctly estimate the rainfall–landslide relationships. A further issue is taking into account the average moisture conditions prior the triggering event, which reasonably may be crucial in determining the sufficient amount of precipitation.…
La Société française : de 1945 à nos jours
2015
International audience; Du plein emploi des Trente Glorieuses au chômage de masse, de l'explosion de la consommation aux nouvelles formes de précarité, de la démocratisation de l'enseignement aux mutations technologiques, sans oublier les métamorphoses de la famille, la montée de l'écologie... les auteurs de ce dossier dégagent ici les lignes de force qui ont façonné la société française après la Seconde Guerre mondiale. Les illustrations variées, les graphiques et les cartes qui accompagnent ces développements soulignent le passage d'un monde à l'autre.
