Changes in food habits amongst Norwegian adolescents in 2016 and 2019 according to gender and socioeconomic status
2021
Background: Monitoring dietary habits is important in order to identify risk groups and as a basis for targeted public health initiatives. Objective: To study trends in consumption of selected foods and beverages from 2016 to 2019 amongst Norwegian adolescents according to gender and parental education. Design: Repeated cross-sectional study amongst 25,996 adolescents, aged 14–17 years old. Consumption of selected food and beverages was measured by an online food frequency questionnaire and general linear models were applied to estimate changes in dietary habits. Results: Between 2016 and 2019, we observed a reduced frequency of consumption of vegetables (from 4.7 to 4.4 times/week), fruit …

Fractional viscoelastic transversally isotropic Timoshenko beam
2014
In this paper the viscoelastic behavior of pultruded beams has been examined. Pultruded beams are constituted by a polymer infilled with reinforcement in longitudinal direction, while in the orthogonal direction no fiber are present for technological reasons. As a consequence the material has two different behaviors in longitudinal and in orthogonal directions. It follows that pultruded beams are transversally isotropic, and the shear deformation may not be neglected. Based upon the previous observations and assuming for Creep and/or Relaxation test the power law, the constitutive equations are ruled by fractional operators. From constitutive laws, and assuming the Timoshenko beam theory to…
Makroekonomikas vides ietekme uz tautsaimniecības nozaru sistemātisko risku
2021
Pasaulē vērojamas krasas sistemātiskā riska atšķirības starp dažādām tautsaimniecības nozarēm dažādās valstīs, un tas rada jautājumus par šo atšķirību cēloņiem. Par pamatu atšķirībām tiek minēta makroekonomiskās vides ietekme un notikumi tautsaimniecībā, kas atspoguļojas ar pārmaiņām aktīvu tirgos. Taču neviennozīmīgi tiek skaidrots, vai atšķiras tautsaimniecības nozaru jutīgums, vai atšķirīga ir makroekonomikas faktoru ietekme dažādos pasaules aktīvu tirgos. Maģistra darba mērķis ir novērtēt makroekonomikas faktoru ietekmi uz nozaru jūtīgumu pret tautsaimniecības mēroga akciju tirgus tendencēm, salīdzināt rezultātus lielākajos pasaules aktīvu tirgos, kā arī skaidrot makroekonomikas faktoru…
Calcium mediated polyelectrolyte adsorption on like-charged surfaces.
2011
International audience; Monte Carlo simulations within the primitive model of calcium-mediated adsorption of linear and comb polyelectrolytes onto like-charged surfaces are described, focusing on the effect of calcium and polyion concentrations as well as on the ion pairing between polymers and calcium ions. We use a combination of Monte Carlo simulations and experimental data from titration and calcium binding to quantify the ion pairing. The polymer adsorption is shown to occur as a result of surface overcharging by Ca2+ and ion pairing between charged monomers and Ca2+. In agreement with experimental observations, the simulations predict that the polymer adsorption isotherm goes through …
Learning and using English and Swedish beyond the classroom : activity systems of six upper secondary school students
2012
Tämän tutkimuksen tarkoituksena oli katsoa englannin ja ruotsin oppimista koulun ulkopuolella toiminnan teorian ja erityisesti Engeströmin (1987, 1999) toimintajärjestelmämallin näkökulmasta, josta aihetta ei ole aiemmin lähestytty. Tutkimus vastaa seuraaviin kysymyksiin: 1) Ovatko abiturientit enemmän kielenkäyttäjiä vai -oppijoita englannissa ja ruotsissa koulun ulkopuolella? 2) Millaisia eroja ja yhtäläisyyksiä heidän toiminnassaan on englannissa ja ruotsissa? 3) Mitkä tekijät selittävät aktiivisuutta ja passiivisuutta? Tutkimus on toteutettu tapaustutkimuksena. Tutkimusaineistona on kuusi puolistrukturoitua haastattelua. Haastateltavat ovat 18-vuotiaita lukion kolmannen vuosikurssin opi…
Polyphenols Epigallocatechin Gallate and Resveratrol, and Polyphenol-Functionalized Nanoparticles Prevent Enterovirus Infection through Clustering an…
2021
To efficiently lower virus infectivity and combat virus epidemics or pandemics, it is important to discover broadly acting antivirals. Here, we investigated two naturally occurring polyphenols, Epigallocatechin gallate (EGCG) and Resveratrol (RES), and polyphenol-functionalized nanoparticles for their antiviral efficacy. Concentrations in the low micromolar range permanently inhibited the infectivity of high doses of enteroviruses (107 PFU/mL). Sucrose gradient separation of radiolabeled viruses, dynamic light scattering, transmission electron microscopic imaging and an in-house developed real-time fluorescence assay revealed that polyphenols prevented infection mainly through clustering of…
IDENTIFICATION AND QUANTIFICATION OF PHENOLIC COMPOUNDS FROM RED GRAPE POMACE
2018
The wine industry generates a great amount of waste every year, thus its valorization is of most importance. This study uses red, fermented pomace from Cabernet Sauvignon and Feteasca Neagra cultivars. The phenolic compounds were extracted using four different extractions and the content of total polyphenols was determined using a spectrophotometrical method. Several phenolic compounds were analyzed using an HPLC method. The Cabernet Sauvignon pomace had the highest content of total polyphenols and total phenolic compounds analyzed and of quercetin, rutin, ferulic acid and resveratrol, while the Feteasca Neagra pomace had the highest content of gallic acid, syringic acid, cinamic acid and (…
