Julkisen hallinnon verkkosivujen saavutettavuuden tila 2000-luvulla
2012
Tutkielman tarkoituksena oli kartoittaa julkisen hallinnon verkkosivujen saavutettavuutta. Tutkimusongelma nousi esiin nykyisestä suuntauksesta, jossa palveluita siirretään yhä enemmän verkkoon myös julkisen hallinnon toimintojen osalta. Tällöin verkkopalveluiden edellytyksenä on oltava, että ne ovat saavutettavia kaikille kansalaisille. Tutkielmassa esitellään saavutettavuuden arviointiin liittyviä ohjeistuksia, arviointimenetelmiä ja mittausjärjestelmiä. Lisäksi saavutettavuutta lähestytään vammaisuuden näkökulmasta, jolloin keskiössä ovat vammaisuutta käsittelevät teoriat sekä vammaisuuden vaikutukset verkkosivustojen käytölle. Tutkielman aineistona toimivat kansainväliset saavutettavuus…
Accessibility of Public Web Services: A Distant Dream?
2013
Part 1: Long and Short Papers; International audience; Today, many public services are available online through Web sites. The accessibility of the sites, also to people with disabilities, is important because the accessibility concerns equality of citizens, a cornerstone of democracy. In the current study we carried out a meta-analysis of 17 studies concerning the accessibility of the Web sites of public administration. Furthermore, we assessed the accessibility of Web pages of 12 ministries of the Finnish government. The assessments were based on the Web Content Accessibility Guidelines (WCAG). The results showed that in terms of the WCAG guidelines, the average accessibility of public We…
Encapsulation of Xenon by a Self-Assembled Fe4L6 Metallosupramolecular Cage
2015
We report (129)Xe NMR experiments showing that a Fe4L6 metallosupramolecular cage can encapsulate xenon in water with a binding constant of 16 M(-1). The observations pave the way for exploiting metallosupramolecular cages as economical means to extract rare gases as well as (129)Xe NMR-based bio-, pH, and temperature sensors. Xe in the Fe4L6 cage has an unusual chemical shift downfield from free Xe in water. The exchange rate between the encapsulated and free Xe was determined to be about 10 Hz, potentially allowing signal amplification via chemical exchange saturation transfer. Computational treatment showed that dynamical effects of Xe motion as well as relativistic effects have signific…
Différents régimes impulsionnels dans un laser Raman à fibre optique

National audience; Nous rapportons différents régimes impulsionnels observés au sein d'une cavité laser Raman en anneau.
Optical properties of chlorine-and oxygen-related defects in SiO$_2$ glass and optical fibers
2018
International audience; Photoinduced processes involving chlorine molecules in synthetic silica were studied. Interstitial Cl$_2$ in SiO$_2$ are prevented from VIS/UV photolysis by cage effect. However, they react with oxygen interstitials yielding photosensitive ClClO molecules absorbing at 264nm.
Medicago truncatula
2012
In plants, long distance transport of sugars from photosynthetic source leaves to sink organs comprises different crucial steps depending on the species and organ types. Sucrose, the main carbohydrate for long distance transport is synthesized in the mesophyll and then loaded into the phloem. After long distance transport through the phloem vessels, sucrose is finally unloaded towards sink organs. Alternatively, sugar can also be transferred to non‐plant sinks and plant colonization by heterotrophic organisms increases the sink strength and creates an additional sugar demand for the host plant. These sugar fluxes are coordinated by transport systems. Main sugar transporters in plants compri…
The underlying processes governing seed size plasticity: Impact of endoploidy on seed coat development and cell expansion in Medicago truncatula
2019
Prod 2019-55a BAP GEAPSI CT1 BAP; Abstract Bigger seeds represent an agronomic and economic benefit but the breeding and ecological balance between seed size and number is difficult to find. Large seeds associated with other practices can improve crop competitiveness as they are more vigorous and result in healthier crops with higher yields, even under stressful conditions. Applying genomic research and genome-wide association studies to breeding is generating new strategies to improve seed traits and novel insights into the biology of seed development and metabolism that are discussed in this chapter. The DNA amount differs among the seed tissues and amplifying genomic DNA by endocycle ind…
Medicago species affect the community composition of arbuscular mycorrhizal fungi associated with roots
2007
National audience; The symbiosis between plants and arbuscular mycorrhizal fungi (AMF) is ancient and involves 80% of terrestrial plant families. The symbiotic association between AMF and plants was described to be non specific. However, AMF were reported to influence plant community diversity and productivity. On the other way, the effect of plant genotypes belonging to closely related species on AMF diversity has not been explored so far. The aim of this work was to assess the impact of four different Medicago species, M. laciniata, M. murex, M. polymorpha and M. truncatula cv. Jemalong J5, on the composition of AM fungal community, when cultivated in a silty-thin clay soil (Mas d’Imbert,…
Combining ecophysiological and microbial ecological approaches to assess interaction between genotypes of Medicago truncatula and the soil bacterial …
2011
International audience; Microbial communities can play a key role in sustainable agriculture by improving crop growth. Currently, a major stake is to study the effect of the plant genotype on the shaping of the soil microbial communities in relation to the plant nutrition. Methods: The links between the plant genotype and the rhizospheric bacterial communities were assessed at both structural and functional level using a multidisciplinary approach. On the one side, the genetic structure (Automated Ribosomial Intergenic Spacer Analysis (ARISA)) and diversity (454 pyrosequencing) of bacterial communities of the rhizosphere was first analysed. On the other side, using an ecophysiological model…
