Functional Near Infrared Spectroscopy System Validation for Simultaneous EEG-FNIRS Measurements
2019
Functional near-infrared spectroscopy (fNIRS) applied to brain monitoring has been gaining increasing relevance in the last years due to its not invasive nature and the capability to work in combination with other well–known techniques such as the EEG. The possible use cases span from neural-rehabilitation to early diagnosis of some neural diseases. In this work a wireline FPGA–based fNIRS system, that use SiPM sensors and dual-wavelength LED sources, has been designed and validated to work with a commercial EEG machine without reciprocal interference.
Leg extension power asymmetry and mobility limitation in healthy older women
2005
Objective To investigate the association of asymmetry in leg extension power (LEP) with walking and standing balance. Design Cross-sectional analysis. Setting Research laboratory. Participants Healthy female twins (N=419), ages 63 to 75 years. Interventions Not applicable. Main Outcome Measures The LEP difference between the stronger and the weaker leg, measured with the Nottingham power rig, was calculated. Ten-meter maximal walking velocity was assessed in a laboratory corridor on a wide (170cm) and narrow (35cm) track, and the ability to maintain tandem stance for 20 seconds was recorded. Results The mean LEP difference ± standard deviation between the legs was 15%±9% (P<.001). Those wit…
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…

Nanoelektromehānisko slēdžu vadības sistēmas izveide
2018
Izmantojot divus elektrodus un nanovadu ir iespējams izveidot nanoelektromehānisku sistēmu kas darbojas kā mehānisks slēdzis. Nanovads ir pievienots pie viena elektroda, pieliekot līdzstrāvu starp abiem elektrodiem rodas elektriskais lauks, kas noliec nanovadu pie otra elektroda. Palielinot spriegumu panāk to, ka elektriskā lauka spēks pārsniedz nanovada elastības spēku un tas nonāk kontaktā. Lai to panāktu starp elektrodiem jābūt salīdzinoši lielam līdzspriegumam, kas pēc nonākšanas kontaktā var sabojāt nanovadu. Tāpēc tiek pieslēgts arī maiņspriegums, kas izraisa nanovada mehāniskas svārstības un palīdz tam nonākt kontaktā. Kamēr šis slēdzis nav nonācis kontaktā, starp nanovadu un elektro…
How do gender, Internet activity and learning beliefs predict sixth-grade students’ self-efficacy beliefs in and attitudes towards online inquiry?
2021
Today’s students search, evaluate and actively use Web information in their school assignments, that is, they conduct an online inquiry. This current survey study addresses sixth-grade students’ self-efficacy beliefs in and attitudes towards online inquiry, and to what extent free-time and school-related Internet activity, gender and learning beliefs explain these. The questionnaire was administered in 10 schools to 340 sixth-graders in Finland. Exploratory and confirmatory factor analyses revealed three elements of self-efficacy beliefs: self-efficacy in Web searching, the evaluation of sources and synthesising information. Furthermore, attitudes towards online inquiry loaded into two fact…
Gender differences in usage and user experience of Oiva App
2015
Previous research has indicated that gender is an important demographic to consider when designing effective and tailored technology interventions. Despite this need, gender differences is still an understudied topic in the field of technology interventions. The objective of this study was to study gender differences in usage and user experience of a mental wellness app called Oiva. Gender differences in the app’s effect on the participants’ mental well-being were also investigated. Oiva is a stand-alone mental wellness app that aims to increase its users’ psychological flexibility by teaching Acceptance and Commitment Therapy (ACT) based skills. The study population of the current study wa…
Le petit mobilier en fer des habitats du Hallstatt D-La Tène A : un mobilier sous-exploité
2007
Modern excavations of settlement sites from the end of the First Iron Age and the beginning of the second, together with a re-examination of those undertaken in the past, permit us to better approach some material that has traditionally been neglected as a result of its unpromising aspect: notably some of the iron material. This article will attempt to show the diversity of this material, and some new methods permitting its quantification. The aim is to deepen our understanding of the role and status of this metal in Hallstatt society by a consideration of the material from occupation sites as opposed to funerary monuments.
Sur la piste des matériaux organiques grâce à la spectrométrie de masse
2018
Identifying the organic materials present, establishing their origin and degree of preservation, understanding their manufacturing process and their use, all of which require interdisciplinary studies involving closely specialists in materials and human sciences. In this very specific context, mass spectrometry has become a key tool to improve knowledge of past civilizations but also to better preserve and restore the discrete remains of archaeomaterials. The identification of diagnostic molecular markers of natural substances is now a recognized strategy for characterizing amorphous organic materials (fats, beeswaxes, vegetable substances such as resins and tars). New advances have also ma…
