The representation of Sámi people on Finnish and Norwegian tourism websites in English
2014
Tutkielman tarkoituksena oli selvittää, minkälaisia representaatioita saamelaisista rakennetaan norjalaisessa sekä suomalaisessa matkailumarkkinoinnissa englanniksi. Aineistona oli yksi kunkin maan virallisen matkailumarkkinointiportaalin (VisitFinland ja VisitNorway)saamelaisaiheinen alasivu. Tutkielman teoriapohjana käytettiin kriittistä diskurssianalyysia(esim. Fairclough 1992, Pietikäinen & Mäntynen 2009, Blommaert 2005). Taustatietona käytiin läpi aiempia tutkimuksia saamelaisrepresentaatioista. Metodeissa nojattiin pääosin laadulliseen ja monimodaaliseen analysointiin, jossa pohjana oli Fairclough’n (1992) kolmitasoinen diskurssiaineiston analysointi. Tutkimustuloksista kävi ilmi, ett…

Sensory systems sequentially extract increasingly complex features. ON and OFF pathways, for example, encode increases or decreases of a stimulus from a common input. This ON/OFF pathway split is thought to occur at individual synaptic connections through a sign-inverting synapse in one of the pathways. Here, we show that ON selectivity is a multisynaptic process in the Drosophila visual system. A pharmacogenetics approach demonstrates that both glutamatergic inhibition through GluClα and GABAergic inhibition through Rdl mediate ON responses. Although neurons postsynaptic to the glutamatergic ON pathway input L1 lose all responses in GluClα mutants, they are resistant to a cell-type-specifi…

Highly sensitive olfactory biosensors for the detection of volatile organic compounds by surface plasmon resonance imaging
2018
International audience; Nowadays, monitoring of volatile organic compounds (VOCs) is very important in various domains. In this work, we aimed to develop sensitive olfactory biosensors using odorant binding proteins (OBPs) as sensing materials. Three rat OBP3 derivatives with customized binding properties were designed and immobilized on the same chip for the detection of VOCs in solution by surface plasmon resonance imaging (SPRi). We demonstrated that the proteins kept their binding properties after the immobilization under optimized conditions. The obtained olfactory biosensors exhibited very low limits of detection in both concentration (200pM of beta-ionone) and in molecular weight of …
Complex plant quality—microbiota–population interactions modulate the response of a specialist herbivore to the defence of its host plant
2022
Many specialist herbivores have evolved strategies to cope with plant defences, with gut microbiota potentially participating to such adaptations. In this study, we assessed whether the history of plant use (population origin) and microbiota may interact with plant defence adaptation. We tested whether microbiota enhance the performance of Melitaea cinxia larvae on their host plant, Plantago lanceolata and increase their ability to cope the defensive compounds, iridoid glycosides (IGs). The gut microbiota were significantly affected by both larval population origin and host plant IG level. Contrary to our prediction, impoverishing the microbiota with antibiotic treatment did not reduce larv…
Saint-Dizier « la Tuilerie » (Haute-Marne) : trois sépultures d’élite du VIe siècle
2019
In 2002, excavations carried out by Marie-Cécile Truc (Inrap) at Saint-Dizier led to the discovery of four graves of exceptional wealth, containing a young woman, two men and a horse, dated to c. 525-550 AD. Dressed and adorned with numerous jewels, the young female was laid in a coffin upon which were placed vessels in glass, copper alloy goblet and ceramic. Each male had been buried in an excavated funerary chamber, built within an oak frame. They were laid in their coffins along with their personal clothing, including a ceremonial sword with two rings added to the pommel. The larger weapons (throwing axes, shields, lances and angons) as well as various utensils were placed either on the …
Neiromediatora serotonīna ietekme uz augļu mušu (Drosophila melanogaster) kustību lateralitāti
2022
Augļu mušu (Drosophila melanogaster) depresīvā uzvedības modeļa izpēte ar y-tipa labirinta metodi, var palīdzēt saprast depresīvās uzvedības pamatelementus. Augļu mušas ir labi pazīstams un plaši pielietojams modeļobjekts bioloģijas nozares pētījumos, ir zināms, ka serotonīna sintēzes cikls ir evolucionāri konservatīvs, līdzīgs visiem dzīvniekiem, tāpēc ir svarīgi apzināties kādus ķīmiskos līdzekļus vislabāk pielietot tālakos uzvedības pētījumos. Darba mērķis ir izpētīt vai selektīvie serotonīna inhibitori ietekmē augļu mušu Oregon R kustību lateritāti. Kopā pētījumā analizēti, selektīvā serototonīna atpakaļpiesaistes inhibitora escitaloprāma un, vielas ar antidepresīvām īpašībām, triptofān…
Fellmanin suvun Lapponica-kokoelma sen provenancen valossa
2019
Fellmanin suvun Lapponica-kokoelma on mitä arvokkain todistus tieteiden kehityksestä Suomessa 1800- ja 1900-luvun vaihteessa. Tarkastelen artikkelissani kokoelman omistushistoriaa soveltaen provenance-lähestymistapaa. Esittelen kokoelman historiaa, sen luettelointityötä ja tuon eri esimerkein esille, miten nimenomaisesti provenance-tarkastelu tuottaa uutta tietoa ja miten se soveltuu Lapponica-kokoelman tutkimiseen. nonPeerReviewed
Zīlītes atbildes reakcijas izmaiņas dienas laikā
2015
Maģistra darbs uzrakstīts uz 38 lapām, satur 23 attēlus, 4 tabulas, 1 vienādojumu, 2 pielikumus, 29 literatūras avotus. Darba mērķis: Noskaidrot kā izmainās zīlītes atbildes reakcija dienas laikā, izmantojot sinusoidāli modulētus īso un garo gaismas viļņu stimulus ar dažādām frekvencēm. Pētījumā piedalījās 7 dalībnieki, kuriem tika veikti zīlīšu reakcijas mērījumi, pie sinusoidāli modulēta zilās un sarkanās gaismas stimuliem ar divām frekvencēm – 0.25 un 0.50 Hz. Mērījumi tika veikti no rīta un vakarā ar 8 stundu intervālu. Rezultātā tika iegūts, ka vakara mērījumos zīlītes maksimālā diametra vērtība ir mazāka, nekā no rīta. Nav novērojama statistiski nozīmīga atšķirība starp fāzes nobīdēm …
