This chapter illustrates how quantum chemical calculations can be used to elucidate structural and functional aspects of tetrapyrrole cofactors, focusing on porphyrins, cobalamins, coenzyme F430, and chlorophyll. A particular emphasis is put on the biochemical significance of axial ligands, which can tune the function of the tetrapyrroles. With the use of quantum chemical calculations, it is possi

Ystads kommun arbetar med en fördjupning av översiktsplanen för staden Ystad med omnejd. Ystads havsnära läge gör att klimatförändringen kommer att innebära stora utmaningar. Stigande havsnivåer väntas leda till ökade erosions- och översvämningsrisker i kustnära områden. Samtidigt är efterfrågan på havsnära boende stor och kommunen planerar att bygga ut staden mot havet. Författarna har utrett kli

We derive an expression for the acoustic force density acting on an inhomogeneous fluid with a continuous spatial variation in density and compressibility. A key prediction of our theory, validated by confocal imaging in an acoustofluidic microchip, is that inhomogeneous fluid configurations can be stabilized in the presence of destabilizing forces due to gravity or acoustic streaming flows.

Electrical brain activity and eye movements were recorded in 10 intact and 6 unilaterally labyrinthectomized rabbits, each with implanted electrodes. The frequency of optokinetic nystagmus (OKN) and a 10-second aggregate of theta waves in the dorsal hippocampus were determined after exposure of the animals to sound, vibration and optokinetic stimulation. Each stimulus used caused significant incre

New neurons, originating from the subventricular zone, are continuously integrating into neuronal circuitry in the olfactory bulb (OB). Using a transgenic sensor mouse, we found that adult-born OB interneurons express microRNA-125 (miR-125), whereas the pre-existing developmentally generated OB interneurons represent a unique population of cells in the adult brain, without miR-125 activity. Stable

A primary functionality of context aware applications is the retrieval of different types of context data from various context sources and adapting their behavior accordingly. In order to facilitate context aware application development, a context aware middleware must provide an effective context data management and lookup strategy. The use of a traditional index for indexing dynamic context data

This study investigates online material published in reaction to a Science magazine report showing the absence of peer-review and editorial processes in a set of fee-charging open access journals in Biology. Quantitative and qualitative textual analyses are combined to map conceptual relations in these reactions; and to explore how understandings of scholarly communication and publishing relate to

Sustainable development requires a change of values, norms, and capabilities within individuals and societies, and education is a crucial means to achieve these goals. However, transformation is not a simple task as dominant structures due to path-dependency and lock-in processes resist change, put pressure on innovative approaches, and hinder their potential for change. Thus the question is how s

Syfte: Studiens syfte var att öka kunskapen om socioekonomiska faktorers påverkan på barns språkliga förmåga genom att jämföra narrativer producerade av barn vars vårdnadshavare hade olika utbildningsnivå. Metod: Deltagarna i studien var 64 en- och flerspråkiga barn. Inspelningar av deltagarnas produktion av svenska narrativer till bildserier från Multilingual Assessment Instrument for Narratives

The aim of this study is to investigate how staff who work with persons with mental impairment living in supportive housing describe and reflect on the clients´ self-determination and which options and challenges they experience with respect to putting the intent of the Swedish act concerning support and service for people with certain functional impairments (LSS) regarding self-determination into

Early growth and differentiation of the pancreatic endoderm is regulated by soluble factors from the pancreatic mesenchyme. Previously, we demonstrated that N-cadherin-deficient mice lack a dorsal pancreas, due to a critical role of N-cadherin in dorsal pancreatic mesenchymal cell survival. Here, we show that restoring cardiac and circulatory function in N-cadherin null mice by cardiac-specific ex

The construction sector needs to transition toward using bio-based building materials in order to reduce its negative environmental impact. However, it is unclear how exactly such a bio-based future will look like, with different stakeholders in different geographical contexts having different visions of the sector’s future. Based on an extensive collection of expert interviews with stakeholders f
