Transition-edge sensors for particle-induced X-ray emission spectrometry
2018
A transition-edge sensor array has been applied to particle-induced X-ray emission. We have characterized the detector for quantitative analysis and obtained minimum detection limit over two orders of magnitude better compared to a silicon drift detector. We have also studied chemical effects in analysis of Ti, TiO2 and TiN using proton and heavy ion beams. A chemical shift for TiO2 was observed in proton measurements, and relative multiple ionization X-ray satellite line intensities changed between metallic Ti and other compounds with heavy ions. Detection of low energy X-rays down to 0.5 keV was achieved by installing a polycapillary lens in front of the transition-edge sensor array in ex…
Partnership formation and dissolution over the life course: applying sequence analysis and event history analysis in the study of recurrent events
2015
We present two types of approach to the analysis of recurrent events for discretely measured data, and show how these methods can complement each other when analysing co-residential partnership histories. Sequence analysis is a descriptive tool that gives an overall picture of the data and helps to find typical and atypical patterns in histories. Event history analysis is used to make conclusions about the effects of covariates on the timing and duration of the partnerships. As a substantive question, we studied how family background and childhood socio-emotional characteristics were related to later partnership formation and stability in a Finnish cohort born in 1959. We found that high se…
Creating a National Digital Learning Environment for Enhancing University Teachers' Pedagogical Expertise - The Case UNIPS
2019
This article analyses the design, implementation, and evaluation of a nation-wide project to create a common digital solution for university teaching staff’s pedagogical training in Finland. During three years, eight universities collaborated in developing an online learning platform called UNIPS, the University Pedagogical Support system. The areas to develop were A) a learning platform based on technical design principles, B) pedagogical principles, and C) broadening the scope of offered studies. The results have been promising. With a carefully planned timetable, all participating universities were able to produce, test, and offer UNIPS modules in collaboration with other universities on…
Sistemas híbridos orgánicos-inorgánicos en films de Langmuir-Blodgett
2002
ÉCe travail porte sur la formation et la caractérisation de nouveaux systèmes organiques-inorganiques par l'utilisation de films de Langmuir et de la technique de Langmuir-Blodgett. Plusieurs voies ont ainsi été explorées afin d'obtenir des films minces hybrides aux propriétés multiples, en particulier magnétiques. L'utilisation de l'interaction entre monocouches cationiques et des anions présents en sous-phase a ainsi permis l'organisation de différents polyanions inorganiques en structure lamellaire. Cette stratégie a ensuite été généralisée au cas de colloïdes de Bleu de Prusse, composés bimétalliques étendus. Une large étude (de la préparation à la caractérisation) a été consacrée à ces…
La tributación de la pensión compensatoria como consecuencia de la separación o divorcio en españa
2016
The compensation pension is provided for in the Civil Code for cases of separation or divorce in which there are an economic imbalance between the former spouses. This institution generates tax consequences for the taxpayer who paid compensation as well as for the recipient. This article presents and analyzes the tax regime for ex-spouses derived as a result of the establishment of the compensation pension. La pensión compensatoria está contemplada en el Código Civil para los casos de separación o divorcio en los que se produce un desequilibrio económico en entre los excónyuges. Esta institución genera unas consecuencias fiscales para el obligado tributario que debe abonar la compensación, …
Desarrollo de métodos de disolución con capacidad predictiva del rendimiento in vivo de formulaciones farmacéuticas
2019
Los estudios de bioequivalencia permiten el desarrollo de medicamentos genéricos como una vía sustentable para el acceso a medicamentos seguros, eficaces y de calidad. El Sistema de Clasificación Biofarmacéutico (SCB), estableció los factores que determinan la absorción de fármacos por vía oral, con grandes beneficios desde el punto de vista económico y ético. La presente investigación tiene por objetivo desarrollar metodologías in vitro e in situ que permitan predecir el desempeño in vivo de formas farmacéuticas que contienen fármacos de la clase 2 del SCB. Se estudiaron formulaciones sólidas orales de liberación inmediata de candesartán cilexetilo (CDT), valsartán (VAL) y clonazepam (CLZ)…
Perimän ja liikuntaharjoittelun vaikutus ulomman reisilihaksen lihassolutyyppeihin ja kapillarisaatioon
2008
Laine, Tanja 2008. Perimän ja liikuntaharjoittelun vaikutus ulomman reisilihaksen lihassolutyyppeihin ja kapillarisaatioon. Liikuntafysiologian kandidaatin tutkielma. Liikuntabiologian laitos, Jyväskylän yliopisto, 34s. Tutkimuksissa on havaittu, että perimä vaikuttaa lihassolutyyppien jakaumaan ja kapillaritiheyteen (Rico-Sanz ym. 2003). Monet tutkimukset ovat kuitenkin havainneet myös erityyppisten harjoitusten muokkaavan erityisesti II-tyypin solujen jakaumaa (mm. Liu ym. 2002) ja kasvattavan kapillaarien määrää (mm. Zoladz ym. 2005). Tämän tutkimuksen tarkoituksena onkin selvittää, määrittääkö perimä vai liikunta-aktiivisuus enemmän ihmisen lihassolutyyppijakaumaa ja kapillaaritiheyttä.…

Degradation of Lincomycin in aqueous medium: coupling of solar photocatalysis and membrane separation
2005
Abstract The photocatalytic oxidation of a common antibiotic, the lincomycin was carried out in aqueous suspensions of polycrystalline TiO 2 Degussa P25 irradiated by sunlight. In order to improve the performance of the lincomycin degradation a hybrid system consisting of a solar photoreactor with the photocatalyst in suspension coupled with a membrane module, used to confine both photocatalyst and pollutants in the reaction environment, was tested. A preliminary study was carried out in order to determine some kinetics parameters of the drug photodegradation. The influence of initial substrate concentration on the lincomycin photooxidation rate was investigated. The photooxidation rate fol…
