Behavior of rare earth elements in an aquifer perturbed by CO2 injection: Environmental implications
2019
International audience; Three cubic-meters of CO2-saturated water was injected into a subsurface fractured aquifer in a post-mined area, using a push-pull test protocol. Groundwater samples were collected before and after CO2-injection to quantify geochemical changes. CO2-injection initially reduced the pH of water from 7.3 to 5.7, led to the enrichment of major ions (Ca2+, Mg2+, and alkalinity), and dissolved trace metals (including Fe, Mn, As, and Zn) in the groundwater. Rare earth elements (REE) and yttrium concentrations were also measured in these samples before and after CO2 perturbation, to evaluate their behavior. An enrichment of total Y plus REE (REY) occurred. REY fractionation w…
Diffractive Processes at Next-to-Leading Order in the Dipole Picture
2023
Diffraktiiviset prosessit ovat korkean energian rajalla sensitiivisiä kohdehiukkasen gluonijakaumalle, mistä johtuen niiden avulla voidaan tutkia kohdetta kvanttiväridynamiikan epälineaarisessa alueessa. Näiden epälineaaristen ilmiöiden odotetaan johtavan gluonisaturaatioon, jota voidaan kuvata luontevasti värilasikondensaatiksi kutsutun efektiivisen kenttäteorian avulla. Vaikka saatavilla olevassa kokeellisessa datassa onkin vahvoja viitteitä gluonisaturaatiosta, yksiselitteistä merkkiä saturaatiosta ei ole havaittu. Tämän vuoksi on tärkeää parantaa saturaatiolle sensitiivisten prosessien teoreettista ymmärrystä, jotta pystytään löytämään selkeitä eroja kvanttiväridynamiikan lineaarisen ja…
A coumarin based gold(I)-alkynyl complex: a new class of supramolecular hydrogelators
2015
A phosphine-gold(I)-alkynyl-coumarin complex, [Au{7-(prop-2-ine-1-yloxy)-1-benzopyran-2-one}- (DAPTA)] (1), was synthesized and the formation of long luminescent fibers in solution was characterized via fluorescence microscopy and dynamic light scattering. The fibers presented strong blue and green luminescence, suggesting that the gold(I) in the complex increased intersystem crossing due to the heavy atom effect, resulting in a significant increase in triplet emission. The X-ray structure of the fibers indicates that both aurophilic, π–π interactions and hydrogen bonding contribute to their formation in aqueous solvents. peerReviewed
Planning, implementation and evaluation of a team-building programme in a female youth football team : an action research case study
2015
Antunes, Nuno, 2015. Planning, Implementation and Evaluation of a Team-Building Programme in a Female Youth Football Team: an Action Research Case Study. Master's Thesis in Sport and Exercise Psychology. Department of Sport Sciences, University of Jyväskylä. 55 pp It is believed that teams who work well together perform better. Frequently this requires an outside influence, which has been called team-building (TB). TB is a multivariate process and, therefore, should be studied as a multivariate issue. The current study focuses on understanding and describing the use of TB methods rather than directly investigating the effectiveness of the programme. Thus, the purpose was to describe the pla…

Intimate Partner Violence in Finland
2021
High prevalence of intimate partner violence against women and high levels of gender equality in Finland yield to what has been called the “Nordic paradox.” It has been argued that the high level of gender equality has caused the need for IPV interventions and especially the gendered perspective to be overlooked. However, there has been recent and ongoing development in IPV intervention and prevention in regard to perpetrator programs, couple therapy, and programs to address post-separation stalking. Training programs for social and healthcare professionals and the police have been developed, as well as for teachers and other professionals at school. We hope the current government’s new act…

Effects of an eccentric training programme on hamstring strain injuries in women football players
2015
Summary Study aim: to test the hypothesis that an eccentric training programme applied on women football players would reduce the hamstring injury rate by improving thigh muscle balance and, particularly, hamstring strength. Material and methods: three football teams were recruited for this randomised controlled trial. They played in the first and second divisions in Spain. Players were randomised within clubs either to the intervention (eccentric exercises, n = 22) or control (control exercises, n = 21) groups, and randomisation was stratified according to previous history of thigh strains. The eccentric programme was divided into 3 phases, and each phase was composed of 7 weeks. Complianc…
Puumateriaalin kemiallinen käyttäytyminen sulfaattikeiton alkalisessa etanoliesikäsittelyssä
2002
Puun alkalisessa kuidutuksessa hiilihydraatit, pääasiassa hemiselluloosat, päätepilkkoutuvat ns. peeling-reaktion mukaisesti, jolloin reaktiotuotteina syntyy ensisijaisesti alifaattisia karboksyylihappoja. Kyseinen reaktio aiheuttaa huomattavia saantotappioita ja heikentää tuotettavan massan laatua. Hiilihydraattiketjun peeling-reaktio voidaan estää muuntamalla ketjun pelkistävä pääteryhmä kemiallisesti esimerkiksi hapettamalla. Tässä tutkimuksessa hiilihydraattien pelkistävän pääteryhmän hapettaminen tehtiin hapella, jonka imeytymistä alkaliseen esikäsittelyliuokseen tehostettiin etanolilisäyksen avulla. Vertailun vuoksi esikäsittelyjä tehtiin myös pelkällä natriumhydroksidillä typpiilmake…
