Thinking outside the box: effects of modes larger than the survey on matter power spectrum covariance

2012

Considering the matter power spectrum covariance matrix, it has recently been found that there is a potentially dominant effect on mildly non-linear scales due to power in modes of size equal to and larger than the survey volume. This {\it beat coupling} effect has been derived analytically in perturbation theory and while it has been tested with simulations, some questions remain unanswered. Moreover, there is an additional effect of these large modes, which has so far not been included in analytic studies, namely the effect on the estimated {\it average} density which enters the power spectrum estimate. In this article, we work out analytic, perturbation theory based expressions including…

Kielitutkinto porttina Suomeen ja astinkivenä suomen kieleen

2017

Artikkelissa tarkastellaan inkerilaisten paluumuuttajien kasityksia kielitutkinnosta, joka heidan oli suoritettava saadakseen oleskeluluvan Suomeen niin sanotulla inkerilaisstatuksella. Kielitutkinto oli kaytossa vuosina 2003–2016. Tarkastelun kohteena ovat myos taman kielitutkinnon vaikutukset kielenopiskeluun. Aineistona ovat paluumuuttovalmennukseen osallistuneiden, tutkintoon valmistautuneiden henkiloiden (n = 97) vastaukset kyselyyn, jonka he tekivat ennen kielitutkinnon suorittamista. Aineistoa tarkastellaan sisallonanalyysin keinoin. Aineiston perusteella kielenoppijat tiesivat tutkinnon rakenteesta ja sen suorittamisesta tietokoneella. Suorittajat olivat hyvin tietoisia myos siita, …

Estimation of Pyruvic acid in serum and saliva among healthy and potentially malignant disorder subjects – a stepping stone for cancer screening?

2014

Background: According to Warburg’s effect, the rate of glycolysis increases in cancerous cells. This will increase overall levels of pyruvic acid. The present on-going study was conducted to estimate the levels of pyruvic acid in saliva and serum in normal, oral PMD subjects. Material and Methods: A total of 50 subjects in healthy, PMD of the oral cavity individuals were selected based on clinical and histological criteria. Collected saliva and serum samples were subjected to pyruvic acid level estimation using biochemical analysis. Results: Of the 50 participants 25 (13: Males; 12: Females) & 25 (16: Males; 9: Females) were PMD group. Independent samples t test showed statistically signifi…

Biodiverse green roofs in Mediterranean climate. Input and lessons learned from Germany and Switzerland

In the realm of the doctoral program in technologies for sustainability and land restoration, this thesis deepens sustainable and ecological solutions for Mediterranean environment after the German tradition and the Swiss school of green roofs for biodiversity. Specific aims were to: (1) assess the effectiveness of the existing green roofs norms in supporting biodiversity; (2) review methodologies and approaches for the implementation of biodiverse green roofs but also their application for ecological design; (3) identify habitat templates in the Mediterranean ecoregion replicable on green roofs; and (4) investigate the long term vegetation development of unmanaged green roofs in order to g…
