Etude par analyse thermique différentielle des tranformations de phases sur l'iodate de lithium
1986
International audience; Lithium iodate (LiIO3) exists at room temperature either as hexagonal (alpha) or tetragonal (beta) crystals. Beta-LiIO3 is stable up to the melting point, whereas alpha-LiIO3 is known to undergo phase transitions. We have studied by differential thermal analysis (DTA) the sequence of phase transitions occurring on powders prepared by different processes. An alpha-LiIO3 powder obtained by grinding a single crystal exhibits the well-known transformations alpha-gamma-beta. A powder obtained by fast evaporation of an aqueous solution transforms directly the alpha to the beta and does not exhibit any intermediate gamma phase. Further, DTA investigations point out that the…
Developing a framework for designing humanitarian blockchain projects
2021
International audience; Blockchain technology promises to improve the efficiency, transparency, and accountability of humanitarian operations. Yet at the same time, especially the humanitarian context with its characteristic volatility poses unique challenges to any technology. Most prominent are the humanitarian principles that are fundamental to humanitarian operations. These ethical principles are set to protect the most vulnerable populations. Designing blockchain projects in the humanitarian context therefore requires a systematic framework that helps humanitarians make critical choices.While some design instructions can be found for commercial applications, the humanitarian context re…
Combustion wave structure during the MoSi2 synthesis by Mechanically-Activated Self-propagating High-temperature Synthesis (MASHS): In situ time-reso…
2006
Abstract In situ synchrotron time-resolved X-ray diffraction experiments coupled with an infrared imaging camera have been used to reveal the combustion wave structure during the production of MoSi2 by Mechanically Activated Self-propagating High-temperature Synthesis (MASHS). The fast combustion front exhibits a form described as an ‘equilibrium structure’ where the chemical reaction is the sole major driving force. In the MASHS process, oxide-free interfaces between Mo and Si nanocrystallites enhance the reaction Mo+2Si→MoSi2. Exhaustive time-resolved investigations show a possible solid-state process in the first second of the reaction within the combustion front. If preheating is added,…
Factors Influencing the Usage Behavior of Digitalized Innovation Environments in Companies : A Qualitative in-Depth Analysis
2021
Digital Innovation Environments (DIE) as an umbrella term for facilities such as FabLabs, Makerspaces and Innovation Laboratories are already well known in the private and academic sectors. We focus on exploring the business aspects of DIEs and their role in digital transformation and creation of new opportunities for companies to increase their knowledge transfer and innovation capabilities. This research is dedicated to factors influencing the usage behavior of company employees of a DIE. From seven guided interviews, a total of 27 influencing factors in seven topics were identified through successive in-depth analysis and criterion-guided interpretation. These factors show the complexity…
Adenovirus E1A/E1B Transformed Amniotic Fluid Cells Support Human Cytomegalovirus Replication.
2015
The human cytomegalovirus (HCMV) replicates to high titers in primary human fibroblast cell cultures. A variety of primary human cells and some tumor-derived cell lines do also support permissive HCMV replication, yet at low levels. Cell lines established by transfection of the transforming functions of adenoviruses have been notoriously resistant to HCMV replication and progeny production. Here, we provide first-time evidence that a permanent cell line immortalized by adenovirus type 5 E1A and E1B (CAP) is supporting the full HCMV replication cycle and is releasing infectious progeny. The CAP cell line had previously been established from amniotic fluid cells which were likely derived from…
Sustainable agriculture: Recognizing the potential of conflict as a positive driver for transformative change
2020
International audience; Transformative changes in agriculture at multiple scales are needed to ensure sustainability, i.e. achieving food security while fostering social justice and environmental integrity. These transformations go beyond technological fixes and require fundamental changes in cognitive, relational, structural and functional aspects of agricultural systems. However, research on agricultural transformations fails to engage deeply with underlying social aspects such as differing perceptions of sustainability, uncertainties and ambiguities, politics of knowledge, power imbalances and deficits in democracy. In this paper, we suggest that conflict is one manifestation of such und…
From everyman's right to everyman's possibility
2016
This article describes a blended learning study module that was carried out in class teachers’ adult education. The goal of the planning of this module was to create a learning environment that would give a student an optimal learning experience in versatile, authentic, e-learning environments. In the study, the ubiquitous learning model was based on the principles of transformational pedagogy (OED). The module was carried out in flexible and versatile learning environments based on transformational pedagogy, where knowledge also included command of the 21st century teaching skills 21. The theoretical framework of the study module followed the model of contextual-pedagogical model [18]. The…

Jokamiehen oikeudesta jokamiehen mahdollisuudeksi
2016
Uudenlaisten pedagogisten mallien pohjalle suunnitellut opintokokonaisuudet lisäävät yliopistojen opintotarjonnan saavutettavuutta ja antavat yksilöille paremmat mahdollisuudet elinikäiseen oppimiseen. Luokanopettajien aikuiskoulutuksessa on käynnissä laaja oppimisympäristöjen kehittymistyö, jossa e-oppimisella on näkyvä sija. Aikuisopiskelijoiden elämäntilanne luo haasteita täysipäiväiselle läsnäololle ja siitä noussut tarve on nähty Luokanopettajien aikuiskoulutuksessa myös mahdollisuutena laajentaa henkilökunnan pedagogista osaamista uudistavien e-oppimiskäytänteiden ja pedagogisten mallien suunnittelijoina, kehittäjinä ja toteuttajina. Luokanopettajien aikuiskoulutuksen 25-vuotinen taiv…
The Future is Now : UAS Language Education in Transition
2019
The current article discusses how the increasing student diversity and transformation of work challenge language education at the Finnish universities of applied sciences (UAS). The article highlights some administrative and pedagogical solutions that have been developed at Karelia UAS to enable the progress of diverse students towards professional competence in foreign languages necessitated by the changes in the labour market. The aim of this article is to evoke discussion on the future directions of language education in vocational higher education. nonPeerReviewed
