The influence of weathering processes on labile and stable organic matter in Mediterranean volcanic soils
2008
The relationship and mechanisms among weathering processes, cation fluxes, clay mineralogy, organic matter composition and stability were studied in soils developing on basaltic material in southern Italy (Sicily). The soils were transitions between Phaeozems and Vertisols. Intense losses of the elements Na, Ca and Mg were measured indicating that weathering has occurred over a long period of time. The main weathering processes followed the sequence: amphibole, mica, volcanic glass or if ash was the primary source→smectite→interstratified smectite–kaolinite→kaolinite. Kaolinite formation was strongly related to high Al, Mg and Na losses. The good correlation between oxyhydroxides and kaolin…
The emission reduction potentials of First Generation Electric Aircraft (FGEA) in Finland
2020
Under the looming climate crisis, aviation needs to find new solutions to cut its greenhouse gas emissions. One pathway towards zero emissions is the use of electric aircraft. While current battery technology will not allow for medium and long-haul flights at full capacity, on short-haul routes First Generation Electric Aircraft (FGEA) could play a significant role in the near future. Current FGEA under development could carry 9–19 passengers on distances of 400–1046 km by 2025. This study focuses on the emissions reduction potentials of FGEA in Finland. It compares the carbon dioxide equivalent (CO2-eq) emissions and real travel times (RTT) from door-to-door of FGEA on 47 routes with exist…
Beauty and Splendour - Le Arti Decorative siciliane nei diari dei viaggiatori inglesi tra XVIII e XIX secolo
2018
Scientific study of the testimonies taken from the diaries of English travellers between the 18th and 19th centuries on the Sicilian Decorative Arts.
Displacing Victorian Women: Mid-Nineteenth Century Popular Drama and the Representation of Female Identity
2019
La presente tesis contribuye al actual interés por rescatar las cuestiones de género más obviadas u olvidadas del siglo XIX. Principalmente, se establece la década de los sesenta (1860–1870) como década precursora al movimiento sufragista inglés de finales de siglo y se ofrece una visión temprana de las estrategias adoptadas por las mujeres victorianas para traspasar la constrictiva ideología de género de la época. Comenzamos cuestionándonos los motivos por los cuales las mujeres de los sesenta decidieron empezar su viaje o ‘journey’ hacia la emancipación, así haciendo referencia a la supuesta pasividad o ‘docilidad’ de las mujeres. Además, establecemos los vínculos existentes entre los mov…
Els viatges de la física: perseguint ombres, mesurant meridians
2013
A partir del segle XVII l’estudi acurat i resolució de diversos problemes de la física, principalment relacionats amb l’astronomia i la forma de la Terra, però no sols, ha passat per realitzar mesures a diferents llocs i, per tant, per l’organització de viatges científics amb aquests objectius específics. Presentarem alguns d’aquests problemes i les solucions adoptades a l’època.

Map-based assessment of older adults’ life space: validity and reliability
2020
Background Map-based tools have recently found their way into health-related research. They can potentially be used to quantify older adults’ life-space. This study aimed to evaluate the validity (vs. GPS) and the test-retest reliability of a map-based life-space assessment (MBA). Methods Life-space of one full week was assessed by GPS and by MBA. MBA was repeated after approximately 3 weeks. Distance-related (mean and maximum distance from home) and area-related (convex hull, standard deviational ellipse) life-space indicators were calculated. Intraclass correlations (MBA vs. GPS and test-retest) were calculated in addition to Bland-Altman analyses (MBA vs. GPS). Results Fifty-eight older …
Psychometric properties of the MOBITEC-GP mobile application for real-life mobility assessment in older adults
2022
Aim of this study was to test the reliability and validity of the life-space measures and walking speed delivered by the MOBITEC-GP app. Participants underwent several supervised walking speed assessments as well as a 1-week life-space assessment during two assessment sessions 9 days apart. Fifty-seven older adults (47.4% male, mean age= 75.3 (±5.9) years) were included in the study. The MOBITEC-GP app showed moderate to excellent test-retest reliability (ICCs between 0.584 and 0.920) and validity (ICCs between 0.468 and 0.950) of walking speed measurements of 50 meters and above and of most 1-week life-space parameters, including life-space area, time spent out-of-home, and action range. T…
Exploring land snails’ response to habitat characteristics and their potential as bioindicators of riparian forest quality
2021
Abstract Riparian ecosystems are crucial for landscape-level biodiversity, especially in highly anthropic and agricultural areas. Although the low mobility of snails reduces their dispersal capacity and makes them vulnerable to habitat degradation, they are less commonly used as indicators. We evaluated the potential of land snails as bioindicators of riparian forest quality in central European riparian forests by surveying snail communities in relation to habitat characteristics that characterize its quality. Habitat characteristics were found to affect both snail abundance and species richness. The abundance of snail species increased with the forest continuity, forest width and abundance…
Mismatch, Empowerment, Fatigue or Balance? Four scenarios of physical activity up to 2030 in Finland
2022
Sedentary lifestyles and the lack of physical activity (PA) are a major concern among all age groups, and current generations tend to be less fit than the previous ones in the Western World. At the same time, there is an urgent need to cut transport-related carbon dioxide (CO2) emissions. Major gains can be foreseen if current car-centred lifestyles and sedentary behaviour are addressed from an integrated perspective. In this study, we explore future scenarios in the intersections of PA and active lifestyles as well as related environmental and health benefits in Finland. We used a disaggregative Delphi approach to examine the topic. Although frequently used in health-related research, Delp…
