Thermoelectric radiation detector based on a superconductor-ferromagnet junction : Calorimetric regime
2018
We study the use of a thermoelectric junction as a thermal radiation detector in the calorimetric regime, where single radiation bursts can be separated in time domain. We focus especially on the case of a large thermoelectric figure of merit ZT affecting significantly, for example, the relevant thermal time scales. This work is motivated by the use of hybrid superconductor/ferromagnet systems in creating an unprecedentedly high low-temperature ZT even exceeding unity. Besides constructing a very general noise model which takes into account cross correlations between charge and heat noise, we show how the detector signal can be efficiently multiplexed by the use of resonant LC circuits givi…
Field dependence of the vortex-core sizes in dirty two-band superconductors
2019
We study the structure of Abrikosov vortices in two-band superconductors for different external magnetic fields and different parameters of the bands. The vortex core size determined by the coherence lengths are found to have qualitatively different behaviour from that determined by the quasiparticle density of states spatial variation. These different vortex core length scales coincide near the upper critical field, while the discrepancy between them becomes quite significant at lower fields. Within the diffusive approximation we demonstrate several generic regimes in the field dependence of the vortex core sizes determined by the disparity of diffusion constants in the two bands.
Making the case for policy : persuasiveness in higher education, science and technology policy discourse
2015
Policy texts present problems, propose solutions to those problems and persuade multiple audiences of the legitimacy of the proposed problems and solutions. The rhetorical analysis of two decades of higher education and science and technology discourse in Finland, Germany, UK, Portugal and USA highlights the discursive elements that contribute to persuasiveness of policy, construe it as rational and logical, and create a sense of urgency in bringing it about. I argue that the analytical and hortatory registers of policy discourse foreground competitive and hierarchical relations of countries and their higher education systems. By construing certain state of affairs and courses of action as …

Tehostettu palveluasuminen psyykkisen ja sosiaalisen elämänlaadun näkökulmasta
2016
TIIVISTELMÄ Karlsson, K. 2016. Tehostettu palveluasuminen psyykkisen ja sosiaalisen elämänlaadun näkökulmasta. Terveystieteiden laitos, Jyväskylän yliopisto, gerontologian ja kansanterveyden pro gradu –tutkielma, 37 s. Tehostetussa palveluasumisessa asuu entistä enemmän ja entistä huonokuntoisempia asukkaita, mikä haastaa kehittämään tehostettua palveluasumista asukkaiden elämänlaadun edellytyksiä parhaiten tukevaksi. Vanhuspalvelulaki (980/2012) velvoittaa palveluasumisessa riittävään henkilökuntamitoitukseen, sosiaalisen vuorovaikutuksen ja osallistumisen mahdollistamiseen sekä turvallisen ja merkityksellisen elämän turvaamiseen. Tämän tutkimuksen tarkoituksena oli selvittää sitä, millais…
Quasiparticle properties of nonequilibrium gluon plasma
2018
We apply classical gluodynamics to early stages of ultrarelativistic heavy-ion collisions. We start by giving a brief overview of QCD. Then we proceed to the space-time evolution of ultrarelativistic heavy-ion collisions in the color glass condensate framework and go through the basics of real-time gluodynamics on the lattice in the temporal gauge. We study the plasmon mass scale in three- and two-dimensional systems by comparing three different methods to measure the mass scale. The methods are a formula which can be derived from Hard Thermal Loop effective theory at leading order (HTL), the effective dispersion relation (DR) and measurement of the plasma oscillation frequency triggered by th…
Microalgae-bacteria consortia for urban wastewater treatment
2021
Los consorcios de microalgas y bacterias surgen como una opción idónea en el marco de las tecnologías sostenibles para el tratamiento de aguas residuales. Los mecanismos de eliminación de contaminantes son el resultado de interacciones ecológicas directas y/o indirectas entre las microalgas y las bacterias autóctonas de las aguas residuales. Para diseñar sistemas eficaces que incorporen consorcios de microalgas y bacterias es necesario comprender las interacciones ecológicas entre ambas comunidades dentro de los procesos de tratamiento de aguas residuales. El objetivo principal de este trabajo de investigación es, por tanto, estudiar y explorar las interacciones ecológicas para mejorar el t…
Self-regulatory efficacy and sources of efficacy in elementary school pupils: Self-regulatory experiences in a population sample and pupils with atte…
2019
In this study, we examined self-regulatory efficacy and sources of self-efficacy (mastery experiences, vicarious experiences, social persuasion and physiological/emotional states) and the relationships between self-efficacy and its sources among elementary school pupils. Two groups were compared: a population sample (PS, N = 1284) and pupils with difficulties in attention and executive functions (AED, N = 61). Data gathered from self-report questionnaires indicated that pupils in the PS group had more positive efficacy beliefs and mastery experiences and fewer negative physiological/emotional states than the AED group. Analyses showed strong connections between sources and self-regulatory e…
La eutrofización en los lagos someros mediterráneos: aplicabilidad de la DMA y un caso de estudio experimental en mesocosmos
2013
Este trabajo se centra en su mayor parte en el estudio de los efectos más directos de la eutrofización en los lagos someros mediterráneos y en el funcionamiento ecológico de este tipo de lagos cuando son sometidos a un incremento en la carga de nutrientes y a la presencia de peces. El trabajo también aborda el estudio de las metodologías más apropiadas para la evaluación de estos lagos mediante la aplicación de la Directiva Marco Europea del Agua (DMA). Este trabajo tiene dos secciones principales, siendo cada una parte de dos proyectos europeos que incluían lagos someros de distintas localidades europeas:(1) El proyecto SWALE que pretendía establecer las diferencias en el funcionamiento ec…
