Azimuthally Differential Pion Femtoscopy in Pb-Pb Collisions at √sNN = 2.76 TeV

2017

We present the first azimuthally differential measurements of the pion source size relative to the second harmonic event plane in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon pair of √ s N N = 2.76     TeV . The measurements have been performed in the centrality range 0%–50% and for pion pair transverse momenta 0.2 < k T < 0.7     GeV / c . We find that the R side and R out radii, which characterize the pion source size in the directions perpendicular and parallel to the pion transverse momentum, oscillate out of phase, similar to what was observed at the Relativistic Heavy Ion Collider. The final-state source eccentricity, estimated via R side oscillations, is found to b…

Honeybees affect floral microbiome composition in a central food source for wild pollinators in boreal ecosystems

2021

AbstractBasic knowledge on dispersal of microbes in pollinator networks is essential for plant, insect, and microbial ecology. Thorough understanding of the ecological consequences of honeybee farming on these complex plant–pollinator–microbe interactions is a prerequisite for sustainable honeybee keeping. Most research on plant–pollinator–microbe interactions have focused on temperate agricultural systems. Therefore, information on a wild plant that is a seasonal bottleneck for pollinators in cold climate such as Salix phylicifolia is of specific importance. We investigated how floral visitation by insects influences the community structure of bacteria and fungi in Salix phylicifolia inflo…

Plasma diagnostic tools for ECR ion sources : What can we learn from these experiments for the next generation sources

2019

International audience; The order-of-magnitude performance leaps of ECR ion sources over the past decades result from improvements to the magnetic plasma confinement, increases in the microwave heating frequency, and techniques to stabilize the plasma at high densities. Parallel to the technical development of the ion sources themselves, significant effort has been directed into the development of their plasma diagnostic tools. We review the recent results of Electron Cyclotron Resonance Ion Source (ECRIS) plasma diagnostics highlighting a number of selected examples of plasma density, electron energy distribution, and ion confinement time measurements, obtained mostly with the second-gener…

Identifying Finnish Children’s Impulsivity Trajectories From Kindergarten to Grade 4: Associations With Academic and Socioemotional Development

2015

Research Findings: The purpose of this study was to identify the developmental trajectories of impulsive behavior among 378 Finnish children who were followed from kindergarten to fourth grade. In addition to ratings of children’s impulsivity, the analyses included measures of motivation, cognitive skills, socio-emotional adjustment, and teacher–student relationship. Four latent groups were identified that differed in the level and change of the children’s impulsive behavior across time: first, a group with low impulsivity; second, a group with decreasing impulsivity; third, a group with moderate impulsivity; and, fourth, a small group with a contradictory trajectory showing an upward trend…

Restoring Harmony in the Lifeworld? : Identity, Learning, and Leaving Preelite Sport

2020

Sport provides many youth participants with a central life project, and yet very few eventually fulfill their athletic dreams, which may lead them to disengage from sport entirely. Many studies have explored the processes of athletic retirement, but little is known about how youth athletes actually reconstruct their relationship with sport and embodiment postretirement. The authors explored these issues in the story of “Pilvi,” a Finnish alpine skier who disengaged from sport in her late adolescence. Employing an existential-phenomenological approach, they conducted six low-structured interviews with Pilvi, combined with visual methods, and identified key themes relating to the body, space,…

Ordinary muon capture studies for the matrix elements in ββ decay

2018

Precise measurement of $\gamma$-rays following ordinary (non-radiative) capture of negative muons by natural Se, Kr, Cd and Sm, as well as isotopically enriched $^{48}$Ti, $^{76}$Se, $^{82}$Kr, $^{106}$Cd and $^{150}$Sm targets was performed by means of HPGe detectors. Energy and time distributions were investigated and total life time of negative muon in different isotopes was deduced. Detailed analysis of $\gamma$-lines intensity allows to extract relative yield of several daughter nuclei and partial rates of ($\mu$,$\nu$) capture to numerous excited levels of the $^{48}$Sc, $^{76}$As, $^{82}$Br, $^{106}$Ag and $^{150}$Tc isotopes which are considered to be virtual states of an intermedia…

Mielikuvien käyttö laulunopetuksen työvälineenä

2015

Laulunopiskelu vaatii useiden eri lihasten kontrolloinnin opettelemista. Koska suuri osa näistä lihaksista ei ole tahdonalaisia, käytetään niiden harjoittamisessa erilaisia mielikuvia. Tämän lisäksi mielikuvien käyttäminen laulunopetuksessa on perusteltua, sillä laulaja ei voi nähdä ääni-instrumenttiaan. Mielikuvien avulla laulaja oppii hahmottamaan ja aistimaan kehoaan paremmin ja niillä voi vaikuttaa huomattavasti jopa kokonaisen kuoron sointiin. Jotta pystymme ymmärtämään, mitä mielikuvien kautta halutaan saavuttaa, täytyy ensin tietää, miten ääni-instrumentti toimii. Jokaisella meistä on yksilöllinen ääni-instrumentti, jonka toiminta koostuu juuri mielen ja kehon yhteistoiminnasta. Laul…
