The landscape of childhood. A study of young adults’ memories in the face of childhood nature

2022

I denne studien undersøker vi hvilke minner som kommer til syne når unge voksne møter barndommens nærnatur igjen, og hvordan kan vi forstå disse minnene. Arbeidet tar utgangspunkt i en kulturell fenomenologisk forståelse. Åtte unge voksne har gått tilbake til sine barndomssteder i skolens nærnatur sammen med en av forskerne. De har gått, klatret og snakket om friluftsliv, lek og lekesteder ute i barndommen. Metoden åpner for å studere komplekse, kroppsliggjorte og stedsspesifikke minner og erfaringer knyttet til konkrete steder, aktiviteter og sosiale relasjoner. Teoretisk bygger studien på fenomenologen Merleau-Pontys beskrivelser av hvordan mennesker bebor verden, Rosas teori om resonans …

Phenomenology of low-scale Seesaw Models

2016

All the observed particles are well accommodated in the Standard Model, together with the basic forces. However, there are both experimental and theoretical hints that the Standard Model can not be a complete theory and that New Physics is needed. Some of the theoretical problems are: i) The flavor-puzzle, i.e., why are there three copies of particles differing only by their mass. Most of the free parameters in the Standard Model are linked to this puzzle. They have been measured, but their values do not follow any clear pattern and their origin remains elusive. ii) The strong CP problem, that is, why the CP symmetry is conserved in the strong interactions in the Standard Model, which is no…

Sterilization of three-dimensional tissue engineering scaffolds by supercritical carbon dioxide

2014

Medical devices, implants or patient-care equipment that will come into intimate contact with a patient must be effectively decontaminated to prevent infection or disease transmission. Non-sterile devices have significant ramifications for patient morbidity and mortality and two processes must be undertaken in order to make an item acceptable for use or implantation: cleaning and disinfection (or sterilization) [1]. Sterilization is the destruction of living organisms, and must be done without damaging the material surface and without compromising the bulk material strength or biocompatibility of implantable device. Common sterilization processes include steam autoclaving, gamma irradiation…

Quantitative reconstruction of hydroclimate variability over the last 200 kyr in the West Mediterranean

2022

The data show the quantitative annual, winter and summer precipitation reconstructions (mm/yr) from southern Iberian Peninsula for the last ~200,000 years (Camuera et al., 2022), based on the previously published fossil pollen data from the Padul-15-05 lake sediment record (Ramos-Román et al., 2018a, b; Camuera et al., 2019, 2021). The Padul-15-05 record, located in southern Spain (37º00'39''N, 3º36'14''W, 726 masl), was retrieved during summer 2015 from the current edge of the lake using a Rolatec RL-48-L hydraulic percussion coring machine. The quantitative precipitation reconstructions were performed using the performance statistics of the Weighted Averaging-Partial Least Squares (WA-PLS…

Âzykovaâ i ètničeskaâ identičnost' lûdej s udmurtskimi kornâmi : na osnove oprosa

2016

Tässä pro gradu -tutkielmassa tarkastellaan 18–30-vuotiaiden udmurttisukuisten etnistä ja kielellistä identiteettiä. Tutkielmassa selvitän, miten 18–30 vuotiaat suhtautuvat omaan etniseen ja kielelliseen perimäänsä ja millä tavalla udmurtin kieli ja kulttuuri ovat säilyneet heidänelämässään. Tämän lisäksi tarkastellaan tärkeimpiä udmurtin kielen ja kulttuurin säilymiseen vaikuttavia seikkoja sekä sitä miltä udmurtin kielen tulevaisuus näyttää tutkimuksen tulosten perusteella. Tutkimuksen aihe on ajankohtainen niin Venäjän valtion kuin udmurtin kielen ja kulttuurin kannalta. Venäjä on monikansallinen ja -kielinen valtio, jossa vähemmistökansojen kielen ja kulttuurin asema kuuluu jokapäiväisi…

Inkeriläisten paluumuutto ja kielitutkinto sen osana

2020

Tässä artikkelissa tarkastellaan inkeriläisten paluumuuttoa heille räätälöidyn kielitutkinnon näkökulmasta. Artikkeli pohjautuu joulukuussa 2019 tarkastettuun väitöskirjaani, jossa analysoin vuosina 2003–2016 käytössä olleelle inkeriläisten kielitutkinnolle asetettuja tavoitteita, tutkinnon vaikutuksia suomen kielen opetukseen ja opiskeluun sekä paluumuuttoprosessia mediassa. Tutkimus valottaa eri näkökulmia kielitutkinnon syntyä edeltävästä keskustelusta. Aineisto osoittaa, että kielenoppijat suhtautuivat kielitutkintoon myönteisesti. Tutkinnon vaikutukset opetukseen ja oppimiseen (washback) olivat pääosin toivottuja. Paluumuuton päättövaiheen mediateksteissä vuosina 2015–2017 Suomessa asu…

Supercritical carbon dioxide induces sterilization of PLLA scaffolds contaminated by E. coli.

2014

The common sterilization techniques are based on physical processes that involve, for example, the use of autoclaves or systems to radiation such as γ-rays that can cause a structural change of the polymer treated. Therefore, the use of supercritical carbon dioxide (scCO2) is an excellent alternative, as it does not induce any variation of biomaterials treated (Perrut M., 2012). It's a good candidate because is readily available at low cost, non-toxic and non-flammable, it has an easily accessible critical point (7.38 MPa and 304.2 K) and excellent transport properties and wettability (White A. et al., 2005). We report the development of a supercritical CO2 based process capable of steriliz…

Topological polarization, dual invariants, and surface flat band in crystalline insulators

2020

We describe a three-dimensional crystalline topological insulator (TI) phase of matter that exhibits spontaneous polarization. This polarization results from the presence of (approximately) flat bands on the surface of such TIs. These flat bands are a consequence of the bulk-boundary correspondence of polarized topological media, and contrary to related nodal line semimetal phases also containing surface flat bands, they span the entire surface Brillouin zone. We also present an example Hamiltonian exhibiting a Lifshitz transition from the nodal line phase to the TI phase with polarization. Utilizing elasticity tetrads, we show a complete classification of 3D crystalline TI phases and invar…
