Poincaré Type Inequalities for Vector Functions with Zero Mean Normal Traces on the Boundary and Applications to Interpolation Methods

2019

We consider inequalities of the Poincaré–Steklov type for subspaces of H1 -functions defined in a bounded domain Ω∈Rd with Lipschitz boundary ∂Ω . For scalar valued functions, the subspaces are defined by zero mean condition on ∂Ω or on a part of ∂Ω having positive d−1 measure. For vector valued functions, zero mean conditions are applied to normal components on plane faces of ∂Ω (or to averaged normal components on curvilinear faces). We find explicit and simply computable bounds of constants in the respective Poincaré type inequalities for domains typically used in finite element methods (triangles, quadrilaterals, tetrahedrons, prisms, pyramids, and domains composed of them). The second …

Effects of combined hormone replacement therapy or its effective agents on the IGF-1 pathway in skeletal muscle.

2010

Objectives To investigate the effects of combined hormone replacement therapy (HRT) and its effective agents on the IGF-1 signaling pathway. Design and methods To examine the effects of HRT on skeletal muscle in vivo, we utilized pre- and post-intervention samples from a randomized double blinded trial with 50–57-year-old women. The intervention included the year-long use of either HRT preparation (2 mg 17β-estradiol, E2; 1 mg norethisterone acetate, NETA, n = 10) or placebo (CO, n = 9). Microarray technology and quantitative PCR (qPCR) were used to study the expression of insulin-like growth factor I (IGF-1) and its splice variants as well as IGF-1 receptor, Akt1, mTOR, FOXO1, FOXO3, atrog…

Héroïsme et exotisme. Le militaire à l’épreuve des lointains (1820-1914)

2013

International audience; Il est d’ordinaire coutume de présenter le XIXe siècle comme un siècle peu guerrier.Et, à en juger par ses bornes, il l’est peu en effet. Il clôt d’un côté une longueséquence guerrière d’un quart de siècle, issue des secousses de la Révolution, tandisqu’il sombre, de l’autre, dans le grand cataclysme de 14-18. Dans l’intervalle, lecontinent européen n’a connu que de rares conflits et, hormis la guerre de Crimée,des affrontements relativement circonscrits tant dans la durée que par le nombredes belligérants. Si le constat paraît juste a priori, il demeure toutefois prisonnierdu souvenir-écran qu’imposa le traumatisme de la Grande Guerre, qui a longtempsinterdit d’éval…

Opiskelijan huomion kiinnittyminen simulaation aikana fysiikan oppitunnilla : silmänliiketutkimus autenttisessa ympäristössä

2017

Tässä pro gradu -tutkielmassa tutkittiin opiskelijan huomion kohdetta lukion fysiikan tunnilla. Tutkimuksessa selvitettiin, vastaako opiskelijan visuaalinen huomio opettajan antamia vihjeitä, kun opettaja opettaa luokassa yhteisesti simulaation avulla. Aineiston kerääminen toteutettiin Tobii Pro Glasses 2 -katseenseurantalaseilla ja SRI-haastattelun avulla ja datan analysointiin käytettiin Microsoft Excel -ohjelmistoa. Luotettavuuden arviointiin käytettiin vertauskoodausta. Tutkimustuloksena oli, että opiskelija seuraa opettajan antamia vihjeitä suurimman osan simulaatio-opetuksen ajasta. Opiskelija katsoi 60 % ajasta sinne, minne opettaja haluaa opiskelijoiden katsovan ja 41 % ajasta opete…

Parasite-induced aggression and impaired contest ability in a fish host

2010

Abstract Background Success of trophically transmitted parasites depends to a great extent on their ability to manipulate their intermediate hosts in a way that makes them easier prey for target hosts. Parasite-induced behavioural changes are the most spectacular and diverse examples of manipulation. Most of the studies have been focused on individual behaviour of hosts including fish. We suggest that agonistic interactions and territoriality in fish hosts may affect their vulnerability to predators and thus the transmission efficiency of trophically transmitted parasites. The parasite Diplostomum spathaceum (Trematoda) and juvenile rainbow trout, Oncorhynchus mykiss, were used to study whe…

Technological aspects of horse meat products – A review

2017

Abstract Horse meat and its products can be considered as a food with a high nutritional value. However, due to cases of economically motivated food adulteration by the intentional addition of horse meat beef products in recent years, horse meat has become a controversial issue. Consumer confidence in meat products and the meat industry has diminished, although consumers consider the differences between the food content and the label as the major issue rather than the safety and nutritional characteristics of horse meat. The elaboration of meat products from horse meat (e.g. “cecina”, dry-cured loin, salami, bressaola and pâte) is also an interesting alternative to other traditional meat pr…

Growth of two-dimensional Au patches in graphene pores : a density-functional study

2016

Grafeenin löytämisen myötä kaksiulotteisten (2D) materiaalien tutkimus on edennyt huomattavasti viimeisen vuosikymmenen aikana. Myös 2D-metalleja on tutkittu, ja esimerkiksi atominpaksuinen rautakerros on onnistuttu kokeellisesti luomaan grafeenin reunalle. Metalleista erityisesti kullan on havaittu käyttäytyvän hyvin eri tavalla nanomittakaavassa. Tässä Pro gradu -tutkielmassa on simuloitu kaksiulotteisten kultasaarekkeiden kasvua grafeenin reunalle tiheysfunktionaaliteoriaa (DFT) käyttämällä. Tavoitteena oli selvittää, kuinka kulta-atomit kulkeutuvat grafeenin pintaa pitkin lopulta reunalle, ja asettuvatko kulta-atomit kaksiulotteisesti samaan tasoon grafeenin kanssa. Tulosten perusteella…

Applicability and consequences of the integration of alternative models for CO2 transfer velocity into a process-based lake model

2019

Freshwater lakes are important in carbon cycling, especially in the boreal zone where many lakes are supersaturated with the greenhouse gas carbon dioxide (CO2) and emit it to the atmosphere, thus ventilating carbon originally fixed by the terrestrial system. The exchange of CO2 between water and the atmosphere is commonly estimated using simple wind-based parameterizations or models of gas transfer velocity (k). More complex surface renewal models, however, have been shown to yield more correct estimates of k in comparison with direct CO2 flux measurements. We incorporated four gas exchange models with different complexity into a vertical process-based physico-biochemical lake model, MyLak…

Efficient approach for simulating distorted materials

2010

The operation principles of nanoscale devices are based upon both electronic and mechanical properties of materials. Because these properties can be coupled, they need to be investigated simultaneously. At this moment, however, the electronic structure calculations with custom-made long-range mechanical distortions are impossible, or expensive at best. Here we present a unified formalism to solve exactly the electronic structures of nanomaterials with versatile distortions. We illustrate the formalism by investigating twisted armchair graphene nanoribbons with the least possible number of atoms. Apart from enabling versatile material distortions, the formalism is capable of reducing computa…
