We analyze the Ce3+-Pr3+:Y2SiO5 emission spectra obtained under selective excitation of the two Ce3+ sites in Y2SiO5 and we show clear evidence of direct energy transfer from Ce3+ to Pr3+. Energy transfer microparameters were calculated from the experimental spectral overlap between the Ce3+ emission and the Pr3+ and Eu3+ absorptions from which, the transfer mechanisms Ce3+-> Pr3+ are concluded to

I Landskrona ska det nya bostadsområdet Norra Borstahusen byggas. Genom området rinner Säbybäcken, dit bostadsområden kommer ha sin huvudsakliga avrinning. Syftet med examensarbetet, med önskan från Landskrona stad, har varit att undersöka möjligheterna att införa ett öppet dagvattensystem, särskilt en lösning med svackdiken. För området har en hydrologisk modell skapats sedan tidigare i programme

This text tries to explore the issue of knowledge in relation to ‘participatory processes of decision making’. Writing from an interdisciplinary perspective, the text revises both theories on democracy and on knowledge trying to bridge them in order to highlight the importance of the knowledge dimension for understanding the ‘participatory processes of decision making’(PPDM). The text suggests 3 a

Modeling of riverine dissolved organic carbon (DOC) dynamics is of great importance for the global carbon budget. Impoundment interception changes the travel time of water and DOC from upslope contributing areas, exerting substantial influence on riverine DOC dynamics in the catchments with many impoundments. However, the impact of impoundment interception representation on riverine DOC modeling h

Climate‐warming induced permafrost thaw exposes large amounts of carbon and nitrogen in soil at greater depths below the seasonally‐thawing active layer. The extent to which plant roots can reach and interact with these hitherto detached, deep carbon and nitrogen stores remains unknown. We aimed to quantify how permafrost thaw affects root dynamics across soil depths and plant functional types com

Pretend play is usually defined as an activity wherein objects and actions (but also 7 affective expression, at times) are separated from their original meanings. Its developmental 8 appearance is set around the second year of life, and increases dramatically in duration, 9 frequency and quality when play episodes start becoming more complex, both linguistically 10 and interactionally reaching its

The implementation of continuous processing in the biopharmaceutical industry is hindered by the scarcity of process analytical technologies (PAT). To monitor and control a continuous process, PAT tools will be crucial to measure real-time product quality attributes such as protein aggregation. Miniaturizing these analytical techniques can increase measurement speed and enable faster decision-maki

Background: Allergic contact dermatitis (ACD) caused by hexavalent chromium (Cr(VI)) is often severe and difficult to treat. The content of Cr(VI) in cement can be reduced by, for example, addition of iron(II) sulfate. Since 2005 the content of Cr(VI) in cement is regulated in the EU Directive 2003/53/EC and must not exceed 2 ppm. Since this regulation came into force, ACD caused by cement has

In times of increasing global temperatures and apathy in the face of climatic and social crises, understanding why people do or do not act is critical. Despite high pro-environmental attitudes, most people ignore the reality of climate change in their everyday lives (Moser & Kleinhückelkotten, 2017). This may be a sign for internal conflict and attempts to protect the self from threat (Norgaar

Some microorganisms, like the aerobic soil bacteria, Oligotropha carboxidovorans, have the capability to oxidize the highly toxic atmospheric gas carbon monoxide (CO) into CO2 through CO dehydrogenase enzymes, whose active site contains a bimetallic MoCu center. Over the last decades, a number of experimental and theoretical investigations were devoted to understanding the mechanism of CO oxidatio
