Los museos etnológicos como instrumentos de formación ciudadana para la sostenibilidad
2008
La investigación que se presenta estudia el papel que los museos etnológicos pueden jugar en la educación científica para contribuir a sociedades más sostenibles, dado que dichos museos pretenden mostrar aspectos esenciales de la vida de los grupos humanos y las relaciones que se establecen entre ellos y el medio que les rodea. Pueden ser así un instrumento idóneo para abordar, tanto los problemas locales que afectan a un grupo humano concreto, como los globales a los que ha de hacer frente la humanidad. Se ha analizado en qué medida el contenido de los museos etnológicos incorpora la problemática socioambiental y, a la luz de dicho análisis, se han diseñado herramientas -entre ellas un mus…
MiR-33a Controls hMSCS Osteoblast Commitment Modulating the Yap/Taz Expression Through EGFR Signaling Regulation
2019
Mesenchymal stromal cells (hMSCs) display a pleiotropic function in bone regeneration. The signaling involved in osteoblast commitment is still not completely understood, and that determines the failure of current therapies being used. In our recent studies, we identified two miRNAs as regulators of hMSCs osteoblast differentiation driving hypoxia signaling and cytoskeletal reorganization. Other signalings involved in this process are epithelial to mesenchymal transition (EMT) and epidermal growth factor receptor (EGFR) signalings through the regulation of Yes-associated protein (YAP)/PDZ-binding motif (TAZ) expression. In the current study, we investigated the role of miR-33a family as a (…

K-kertaisesti kiellettyjen uniikkien β-siirtymien faasiavaruusintegraalit
2018
Tässä tutkimuksessa perehdytään K-kertaisesti kiellettyjen uniikkien beetasiirtymien faasiavaruusintegraaleihin. K-kertaisesti kielletyt uniikit beetasiirtymät ovat beetahajoamisten alaryhmä, ja faasiavaruusintegraalit kuvaavat hajoamisreaktion jälkeisiä lopputiloja ja antavat muun muassa tärkeää tietoa siirtymän hajoamisvakiosta. Tutkimuksessa laskettiin numeerisesti faasiavaruusintegraalit useille tunnetuille beetasiirtymille, jotka voivat olla kaksi- tai useampikertaisesti kiellettyjä. Saatua laskentadataa analysoitiin eri näkökulmista. Tärkein näkökulma on kielletyn uniikin beetasiirtymän ja samaa beetahajoamista kuvaavan perus- eli sallitun siirtymän välinen suhde, koska tämä näkökulma…
Fast-timing study of the l-forbidden 1/2+ -> 3/2+ M1 transition in 129Sn
2016
The levels in 129Sn populated from the β− decay of 129In isomers were investigated at the ISOLDE facility of CERN using the newly commissioned ISOLDE Decay Station (IDS). The lowest 1/2+ state and the 3/2+ ground state in 129Sn are expected to have configurations dominated by the neutron s1/2 (l = 0) and d3/2 (l = 2) single-particle states, respectively. Consequently, these states should be connected by a somewhat slow l-forbidden M1 transition. Using fast-timing spectroscopy we have measured the half-life of the 1/2+ 315.3-keV state, T1/2 = 19(10) ps, which corresponds to a moderately fast M1 transition. Shell-model calculations using the CD-Bonn effective interaction, with standard effect…
High temperature ferro-paraelectric phase transition in tris(trimethylammonium) nonachlorodiantimonate(III) (TMACA) studied by X-ray diffraction meth…
2000
Abstract The structure of [NH(CH3)3]3Sb2Cl9, tris(trimethylammonium) nonachlorodiantimonate(III) (TMACA) has been determined at 295 K and 373 K, below and above the high temperature ferro-paraelectric phase transition. In both phases the anionic sublattice of TMACA is built of characteristic two-dimensional (Sb2Cl93−)n polyanionic layers lying in the bc plane. In room temperature, ferroelectric phase (monoclinic, Pc space group) there are three crystallographically non-equivalent trimethylammonium [NH(CH3)3]+ cations. Two of them are located between polyanionic layers and the third one, disordered, inside the cavity formed by six SbCl63− octahedra. In the high temperature paraelectric phase…
Predicting the age at natural menopause in middle-aged women
2021
Objective To predict the age at natural menopause (ANM). Methods Cox models with time-dependent covariates were utilized for ANM prediction using longitudinal data from 47 to 55-year-old women (n = 279) participating in the Estrogenic Regulation of Muscle Apoptosis study. The ANM was assessed retrospectively for 105 women using bleeding diaries. The predictors were chosen from the set of 32 covariates by using the lasso regression (model 1). Another easy-to-access model (model 2) was created by using a subset of 16 self-reported covariates. The predictive performance was quantified with c-indices and by studying the means and standard deviations of absolute errors (MAE ± SD) between the pre…
Subjective financial situation and financial capability of young adults in Finland
2018
A key developmental task in young adulthood is acquiring financial capability (Serido, Shim, & Tang, 2013), meaning competent financial management skills and the responsibilities that these involve. This study extends previous research on the theoretical model of the development of financial capability, including financial confidence (or financial self-efficacy) and financial behavior as factors contributing to subjective and financial well-being. It is part of the Finnish Educational Transitions Studies (FinEdu) longitudinal research project. Participants were 418 young adults aged 24–25 at Time 1 and 26–27 at Time 2. Path and mediation models and Structural Equation Modeling followin…
Multiparameter quantum critical metrology
2022
Single parameter estimation is known to benefit from extreme sensitivity to parameter changes in quantum critical systems. However, the simultaneous estimation of multiple parameters is generally limited due to the incompatibility arising from the quantum nature of the underlying system. A key question is whether quantum criticality may also play a positive role in reducing the incompatibility in the simultaneous estimation of multiple parameters. We argue that this is generally the case and verify this prediction in paradigmatic quantum many-body systems close to first and second order phase transitions. The antiferromagnetic and ferromagnetic 1-D Ising chain with both transverse and longi…
