Characterization of a novel three-dimensional outgrowth model of human bronchial mucosa
2011
Recently it has been hypothesized that a reactivation of the epithelial-mesenchymal trophic unit (EMTU) of the respiratory mucosa, caused by extensive epithelial damage, may be responsible for the pathogenesis of asthma. However, most research on this subject so far has been limited by the unavailability of in vitro models correctly mimicking the three-dimensional architecture of the properly differentiated human bronchial mucosa. For this reason, we have developed a novel 3D outgrowth model, obtained from bronchial biopsies and composed of both human bronchial epithelial cells (goblet and columnar cells) and fibroblasts with their basement membrane. Here we present the preliminary data obt…

Äitien luottamuksen rakentuminen kasvattajiin varhaiskasvatuksen aloituksessa
2020
Vanhempien ja kasvattajien kasvatusyhteistyön sujuvuus heijastuu siihen, millaiseksi varhaiskasvatuksen aloitus muodostuu lapsen kokemuksena. Parhaimmillaan yhteistyön alkuvaihe tukee luottamuksen rakentumista vanhempien ja kasvattajien välille. Tässä artikkelissa kiinnostus kohdistuu luottamuksen rakentumisen prosessiin äitien näkökulmasta. Tarkastelemme miten luottamus kasvattajiin varhaiskasvatuksen instituutiossa rakentuu äitien puheessa heidän pohtiessaan lapsensa ensi kuukausia varhaiskasvatuksessa. Teoriasidonnaisen sisällönanalyysin tuella tutkimme, onko puheesta löydettävissä Rempelin, Holmesin ja Zannanin (1985) kuvaamia luottamuksen rakentumisen tasoja. Aineistona ovat viiden noi…
Instructional Strategies, Discipline and Children’s Participation in Educational Institutions for Children under Three-Years-Old : Cases from Brazil …
2016
In the cultural psychological and educational literature, recent studies have addressed the educational activities and settings for young children, discussing practices and conceptions in different countries. This study approaches early childhood education and care practices as local, historical and social constructions linked to global trends and commitments to children’s well-being. This paper presents qualitative case analysis on discursive practices and mediational tools used in daily activities with children under three years of age.The focus is on cultural conceptions embedded in the educational activities with cases from Brazil and Finland. The analysis builds on the major themes and…
High-Reynolds-number turbulent cavity flow using the lattice Boltzmann method
2018
We present a boundary condition scheme for the lattice Boltzmann method that has significantly improved stability for modeling turbulent flows while maintaining excellent parallel scalability. Simulations of a three-dimensional lid-driven cavity flow are found to be stable up to the unprecedented Reynolds number $\mathrm{Re}=5\ifmmode\times\else\texttimes\fi{}{10}^{4}$ for this setup. Excellent agreement with energy balance equations, computational and experimental results are shown. We quantify rises in the production of turbulence and turbulent drag, and determine peak locations of turbulent production.
R. Ghezzi - Volume measures in non equiregular sub-Riemannian manifolds
2017
In this talk we study the Hausdorff volume in a non equiregular sub-Riemannian manifold and we compare it to a smooth volume. First we give the Lebesgue decomposition of the Hausdorff volume. Then we focus on the regular part, show that it is not commensurable with a smooth volume and give conditions under which it is a Radon measure. Finally we give a complete characterization of the singular part. This is a joint work with F. Jean (ENSTA).
Effect of temperature on anaerobic treatment of black water in UASB-septic tank systems
2007
The effect of northern European seasonal temperature changes and low temperature on the performance of upflow anaerobic sludge blanket (UASB)-septic tanks treating black water was studied. Three UASB-septic tanks were monitored with different operational parameters and at different temperatures. The results indicated the feasibility of the UASB-septic tank for (pre)treatment of black water at low temperatures with respect to removal of suspended solids and dissolved organic material. Inoculum sludge had little effect on COD(ss) removal, though in the start-up phase some poorly adapted inoculum disintegrated and washed out, thus requiring consideration when designing the process. Removal of …
Extended Families as Communities of Religious Experience in Late Seventeenth-Century Eastern Finland
2022
AbstractThis chapter offers an interpretation of extended families as communities of experience in a rural area close to the eastern border of the Swedish realm. Through a case study of lower court records, Kuha examines the social and religious life in a 17th-century farm culminating in the crisis of an extended family. The chapter explores how practices of lived religion shaped the relationship of the community and the individual, and how experiences were negotiated within families and local communities. The analysis highlights the importance of protecting the boundaries of the household as well as the meaning of religious practices in creating cohesion within the community.
Data from the study: Strong temporal dynamics of ecosystem services through succession
2021
We used a nation-wide forest dataset from the Swedish National Forest Inventory (NFI) and the Survey of Forest Soils and Vegetation, covering an area of 400,000 km2 of production forests. The inventory uses a regular sampling grid with a randomly selected starting point covering the whole country, with each tract being surveyed once every 5 years. The tracts, which are rectangular in shape and are of different dimensions in different parts of the country, consists of 8 (in the north) to 4 (in the south) circular sample plots. The circular plots have different radii (5-20 meters) to ensure that the variables recorded characterize the ongoing forest dynamics and management. We used only plots…
Representations of the Life-giving Spring feast in Romanian iconography
2021
This article explores the development of the theme of the Life-giving Spring in Byzantine iconography. The path towards its establishment was initiated at the moment when a representation rule, an original convention was set. Thereafter, because of its diffusion in time and space, the theme became enriched by particular mentalities and sensibilities of the epochs and the communities that adopted it as a form of devotion for the Virgin Theotokos. As a result, the representations we have known so far are extremely varied. Contribution: The final purpose of this approach, as well as its contribution, is to highlight the diverse unity of the iconographic tradition and illustrate both the evolut…
