Family- and classroom-related factors and mother–kindergarten teacher trust in Estonia and Finland
2014
This study examined the role of family-related (mother’s education, depressive symptoms and child’s gender) and kindergarten-related (teacher’s experience, teaching practices and class size) factors in mothers’ and teachers’ mutual trust in Estonia and Finland. Six hundred eighteen (206 Estonian and 412 Finnish) mothers of kindergarten children and their teachers (26 Estonian, 49 Finnish) were participated in the study. Both mothers and teachers filled in the questionnaire on trust; teachers’ teaching practices were observed with early childhood classroom observation measure. The results of multilevel modelling showed that mothers in both countries trusted more in teachers who used child-ce…

Consensus modelling and molecular dynamics studies for the identification of novel telomerase inhibitors as anti-cancer agents
2018
Telomerase plays an important role in early stages of life-maintaing telomere and chromosomal integrity of frequently dividing cells. It turns dormant in most somatic cells during adulthood. However, in cancer cells, telomerase gets reactivated and works tirelessly to maintain the length of telomeres, leading to immortality of cells. Hence, in this study, we have used a combined ligand-based and structure based drug design approach for the identification of novel telomerase inhibitors as anti-cancer agents. We have generated ligand-based QSAR models and structure-based pharmacophores models, according our recent MYSHAPE approach (1), and validated exhaustively. The validated models were use…
ModeLTER : modelling of landscapes and territories over the long term, the members of an European Associated Laboratory (EAL) in CAENTI.
2006
International audience; The aim of this new project is the modelisation of landscapes and territories over the long term. This has been a topic that engaged the proposed research team for several years, particularly in the frame of two European projects, Archeomedes I & II, during the 1990s (Van der Leeuw S., Favory F., Fiches J.- L. (eds.) 2003, Favory F., Girardot J.-J., van der Leeuw S. 2004). Both French and Slovenian teams were involved in the project by Professors S. Van der Leeuw and Z. Stančič. Since this period, the collaboration of French and Slovenian researchers increased in activity, and it finds now a new organization in an European Associated Laboratory, linking archaeologist…

Comparison of a MBR system start-up with and without inoculum: experimental and mathematical model application
2010
The performance of a membrane bioreactor (MBR) system and the extension and mechanisms that lead to the formation of the fouling may differ in relation to the start-up. As a consequence, the MBR start-up may constitute a crucial point that drastically influence the MBR performance in its lifespan. Indeed, the start-up influences the mechanisms of membrane fouling whose effects, in the case of irreversible cake deposition, can be modified only by a chemical membrane washing. In order to gain insights about the effect of the start-up on a MBR system, a MBR pilot plant was build-up and a mathematical model developed. The MBR system was constituted by a hollow fibre membrane module installed in…
A model for wastewater organic removal and fouling development in a SMBR pilot plant
2007
The paper presents the setting up of a mathematical model for membrane bioreactor able to simulate physical-biological wastewater organic removal. The model is basically divided into two sub-models: the first sub-model is basically devoted for the simulation of the biological features and the second one for the physical processes. In particular regarding the biological aspects, the ASM concept has been employed. On the other hand, the physical processes have been modelled considering the deep-bed theory taking into account not only the effect of the physical membrane filtration but also the cake layer effect. This latter operates as a biological membrane leading to a further reduction of th…
Erosion, screening, and migration of tungsten in the JET divertor
2019
The erosion of tungsten (W), induced by the bombardment of plasma and impurity particles, determines the lifetime of plasma-facing components as well as impacting on plasma performance by the influx of W into the confined region. The screening of W by the divertor and the transport of W in the plasma determines largely the W content in the plasma core, but the W source strength itself has a vital impact on this process. The JET tokamak experiment provides access to a large set of W erosion-determining parameters and permits a detailed description of the W source in the divertor closest to the ITER one: (i) effective sputtering yields and fluxes as function of impact energy of intrinsic (Be,…
