Misfit evaluation of dental implant-supported metal frameworks manufactured with different techniques: Photoelastic and strain gauge measurements
2016
This study aims to compare in-vitro the fitting accuracy of implant-supported metal frameworks used for full-arch orthodontic restoration. The hypotheses tested were as follows: (1) for a fixed implant morphology, strains developed within the framework depend on how the framework had been fabricated and (2) stresses transferred to the implant–bone interface are related to the amount of framework misfit. Metal frameworks were fabricated using four different manufacturing techniques: conventional lost-wax casting, resin cement luting, electrospark erosion, and computer-aided design/computer-aided manufacturing milling. Each framework was instrumented with three strain gauges to measure strai…
Digiosallisuuden käsite ja keskeiset osa-alueet : Digiosallisuus Suomessa -hankkeen väliraportti
2021
Digiosallisuus Suomessa -hankkeen tavoitteena on luoda kattava kokonaiskuva digiosallisuuden kansallisesta tilanteesta, hyvistä käytänteistä ja eri tahojen rooleista sekä mittaristo, jota voidaan hyödyntää digiosallisuuden arvioinnissa. Hankkeen väliraportissa on tuotettu kokoava selvitys digiosallisuuden käsitteestä ja määritelmistä eri tieteen- ja hallinnonalojen näkökulmasta. Väliraportissa käydään läpi digiosallisuutta avaavia lähikäsitteitä sekä digiosallisuuden keskeisimpiä osa-alueita. Olennaiseksi jäsennykseksi väliraportissa nousee yksilöiden ja erilaisten käyttäjäryhmien kokemus digiosallisuudesta sekä eri hallinnonalojen ja muiden toimijoiden, kuten kolmannen sektorin ja yrityste…
"Pamiętam, że...". O społecznej konstrukcji pamięci mieszkańców miast Ziem Zachodnich i Północnych na przykładzie Wrocławia
2017
Celem artykułu jest przedstawienie wątków pamięci społecznej, które z jednej strony opierają się na indywidualnym, potocznym doświadczeniu jednostki, z drugiej umieszczane są w społecznie wynegocjowanych ramach pamięci zbiorowej. Artykuł ten wpisuje się również w dyskusję nad miejscami pamięci i ich możliwą treścią - wykraczającą poza podtrzymujące pamięć zbiorową muzea, pomniki, upamiętniające tablice czy cmentarze - realizowaną w codziennym życiu jednostki. Przedmiotem analiz jest pamięć społeczna mieszkańców Wrocławia, ich konstrukcje światów społecznych opierające się na przestrzeni miasta obciążonej obcą kulturowo „pamięcią nieobecnych”.
Application of Broadband Dielectric Spectroscopy to Cultural Heritage: characterization and preservation of ancient paper artwork
2016
Within the cultural heritage the characterization and conservation of artworks based on paper represents a significant issue for both restorers and scientists. The paper deterioration is affected by the degree of hydrolytic and oxidative reactions which occur upon aging. Moreover, the durability of cellulose fibers depends on the intrinsic composition/structure of the paper as well as on the conservation conditions, such as temperature and humidity. The structural and dynamical characterization of the cellulose matrix and of the water confined within its pores is therefore of central interest. Our working hypothesis is that WATER DYNAMICS is one of the main determinants of paper degradation…

Modélisation des effets des systèmes de culture sur la dynamique de la plante parasite orobanche rameuse en interaction avec les adventices
2019
Reducing pesticide use is a major challenge in agriculture and involves developing more sustainable methods that rely on non-chemical cropping techniques and biological regulations according to agroecological principles. Branched broomrape (Phelipanche ramosa (L.) Pomel) is a root parasitic plant which infects crops and causes dramatic yield losses worldwide. Managing broomrape is complex because it requires combining several cropping techniques whithin a global weed management strategy because broomrape is also able to infect non-parasitic weeds. The aim of this thesis was to stynthetize knowledge on branched broomrape dynamics in agroecosystems and to aggregate it within a mechanistic mod…
Spore-forming parasites infecting muscles of freshwater fishes : ecology and epidemiology
2017
Fish parasites may potentially harm fisheries and aquaculture. Infected fish are unusable, even though they would not pose a direct risk to human health. The aim of this thesis was to investigate the ecology and epidemiology of three previously unknown or poorly known spore-forming parasites infecting muscles of economically important fish species. The first novel microsporidian species, here described as Microsporidium luciopercae, was found from pike-perch (Sander lucioperca) and European perch (Perca fluviatilis) and formed opaque-looking patches in the muscles. The second novel microsporidian species, Myosporidium spraguei, was found from pike-perch and burbot (Lota lota) and occurred w…
