The mass-independent isotopic signatures of planetary bodies have been widely used to trace the mixing process that occurred during planet formation. observed variations among meteorite parent further linked modeled mass-weighted mean initial semimajor axes in N -body simulations, assuming a spatial gradient inner protoplanetary disk. However, nucleosynthetic anomalies nonvolatile elements and ...

The Hg isotopic composition of 1-year-old Norway spruce (Picea abies) shoots collected from Saarland cornurbation Warndt, Germany, since 1985 by the German Environmental Specimen Bank, were measured for a better understanding temporal trends sources. data showed that was mainly taken up as gaseous element mercury (GEM) and underwent oxidation in needles; this led to significant decrease δ202Hg ...

Homoacetogenic bacteria are versatile microbes that use the acetyl coenzyme A (acetyl-CoA) pathway to synthesize acetate from CO2 and hydrogen. Likewise, the acetyl-CoA pathway may be used to incorporate other 1-carbon substrates (e.g., methanol or formate) into acetate or to homoferment monosaccharides completely to acetate. In this study, we analyzed the fractionation of pure acetogenic cultu...

Collaborative environments have been evolving and effectively employed in large organisations and are believed to have high potential for Small and Medium Enterprises (SMEs). This chapter shares the findings of a case study that was conducted on twelve companies in order to assess the use of collaborative environments and their adaptation approaches through interviews with senior level managers...

In this paper, we describe an interface to display texts in a fashion adapted to dyslexic readers. In order to help the reading task, we designed several tools geared towards the specific difficulties of this population, e.g. a tendency to lose one’s place within the text, a fluctuating attention or a difficulty to access the syllable level of the words, a process known to be used with new or i...

This paper deals with the qualitative analysis of a model describing the competition between tumor and immune cells. Such competition is characterized by proliferation–destruction phenomena and the interacting entities are characterized by a microscopic state which is modified by interactions. The model also includes the description of the natural trend of immune cells to reach a healthy or sen...

Here we investigated whether hemispheric asymmetry effects can be observed in nonconscious processing with a basiclevel animal categorization (cat/dog) task. We found a significant nonconscious congruency priming effect when the prime was presented in the right visual field/left hemisphere but not when it was presented in the left visual field/right hemisphere when the prime duration was only 1...

Contemporary research on business value has examined the impacts of IT investments at various levels of analysis. This research examines the impacts of IT investments by a partner. The impacts of partner’s investments are examined for the individual firms, as well as for the overall value co-created for the relationship. Further, we examine whether the value that is co-created is in fact approp...

Symba is a Web-based framework designed to support collective activities in a learning context. It has been constructed with a double objective, (1) make students explicitly work out their organization and (2) provide tailorability features to allow the students to decide about the tools and resources they want to be accessible in order to achieve the tasks they have defined. Symba dissociates ...
