Clusterization and Strong Coulpled-Channels Effects in Deuteron Interaction with 9Be Nuclei
2019
Angular distributions of protons, deuterons, tritons and alphaparticles emitted in the d + 9Be reaction at Elab=19.5 and 35.0 MeV have been measured. The elastic scattering channel is analysed in the framework of both the Optical Model and the Coupled-Channel approach. The interaction potential of the d + 9Be system is calculated in the framework of the Double-Folding model using the α + α + n three-body wave function of the 9Be nucleus. The (d, p) and (d, t) one-nucleon-transfer reactions are analysed within the coupledreaction-channel approach. The spectroscopic amplitudes for the different nuclear cluster configurations are calculated. Differential cross sections for the reaction channel…
Viroporins, Examples of the Two-Stage Membrane Protein Folding Model
2015
Viroporins are small, α-helical, hydrophobic virus encoded proteins, engineered to form homo-oligomeric hydrophilic pores in the host membrane. Viroporins participate in multiple steps of the viral life cycle, from entry to budding. As any other membrane protein, viroporins have to find the way to bury their hydrophobic regions into the lipid bilayer. Once within the membrane, the hydrophobic helices of viroporins interact with each other to form higher ordered structures required to correctly perform their porating activities. This two-step process resembles the two-stage model proposed for membrane protein folding by Engelman and Poppot. In this review we use the membrane protein folding …
Modeling of the N-terminal Section and the Lumenal Loop of Trimeric Light Harvesting Complex II (LHCII) by Using EPR
2015
The major light harvesting complex II (LHCII) of green plants plays a key role in the absorption of sunlight, the regulation of photosynthesis, and in preventing photodamage by excess light. The latter two functions are thought to involve the lumenal loop and the N-terminal domain. Their structure and mobility in an aqueous environment are only partially known. Electron paramagnetic resonance (EPR) has been used to measure the structure of these hydrophilic protein domains in detergent-solubilized LHCII. A new technique is introduced to prepare LHCII trimers in which only one monomer is spin-labeled. These heterogeneous trimers allow to measure intra-molecular distances within one LHCII mon…
Mental rotation and mental folding in 7- and 8-year-old children
2016
Mielessä kääntäminen ja mielessä taittelu ovat avaruudellisten representaatioiden mielessä muuntamista. Mielessä kääntäminen muuttaa objektin suunnan, kun taas mielessä taittelussa täytyy kuvitella, miltä objekti näyttää taittamisen jälkeen. Taitoja on tutkittu paljon, mutta silti ei ole varmuutta, ovatko ne samanlaisia vai erilaisia prosesseja. Aiemmat tutkimukset ovat löytäneet yhteyden mielessä kääntämisen ja matematiikan taitojen välille, mutta mielessä taittelun yhteyttä matematiikkaan ei ole osoitettu. Kuitenkin, suurin osa tutkimuksesta on tehty aikuisilla, joten lasten mielessä muuntamisen taitoja ei ole tutkittu yhtä laajasti. Tässä tutkimuksessa tavoitteena oli tutkia mielessä kää…
