Nitrogenase is the only enzyme that can cleave the triple bond in N2, making nitrogen available for all lifeforms. Previous computational studies have given widely diverging results regarding the reaction mechanism of the enzyme. For example, some recent studies have suggested that one of the μ2-bridging sulfide ligands (S2B) may dissociate from one of the Fe ions when protonated in the doubly r
Nitrogenase is the only enzyme that can convert N2 to NH3. Crystallographic structures have indicated that one of the sulfide ligands of the active-site FeMo cluster, S2B, can be replaced by an inhibitor, like CO and OH−, and it has been suggested that it may be displaced also during the normal reaction. We have investigated possible proton transfer pathways within the FeMo cluster during the
The transdisciplinary argument in this article is that the social and ecological unsustainability of modern, globalized capitalism ultimately derives from the design of its central artifact: what Polanyi called all- or general-purpose money. The notion of a singular measure of economic value is a peculiar cultural conception that is inherently at odds with physical reality, yet it pervades modern
Aerobic granular sludge (AGS) plants have gained growing interest and application due to their low energy demand, small footprint, and low operational costs. However, the fulfilment of strict discharge limits for nitrogen and phosphorus, vast seasonal temperature variations, and large peaks in influent flows may pose challenges to the implementation of AGS. Moreover, the knowledge about microbial
In line with recent trends in sociology of migration, the paper presents majorresearch findings on Swedish immigrant organizations (SIOs) and their labor marketintegration activities. Analyses of engagement in these activities are particularlyimportant as Sweden wrestles with significant problems of labor market marginalization, particularly among non-European migrants. Drawing on official dataand
This chapter discusses the implications of discrimination law for the use of post hoc interventions during recruitment processes that involve the ranking of job candidates. It argues that such interventions may assist employers in preventing direct and indirect discrimination by alerting recruiters, and others responsible for hiring decisions, to the fact that biases may have influenced the recrui
In all times, societies have known social hierarchies and boundaries between individuals and groups with distinct social characteristics. The extent to which such hierarchies and boundaries are consequential for life outcomes and persist over time differs between societies. These changes over generations in the social structure, and the social, economical, and institutional developments that shape
The efficient use of softwood in biorefineries requires harsh pretreatment conditions to overcome biomass recalcitrance. Following harsh pretreatments, the hemicellulose is solubilized. Here, we studied the material characteristics of Norway spruce following steam pretreatment at six different severities, relating chemical and structural information to the enzymatic hydrolyzability. Steam pr
Introduction: Functional connectivity (FC)—which reflects relationships between neural activity in different brain regions—has been used to explore the functional architecture of the brain in neurodegenerative disorders. Although an increasing number of studies have explored FC changes in behavioral variant frontotemporal dementia (bvFTD), there is no focused, in-depth review about FC in bvFTD. Me
The lifetime risk of developing atrial fibrillation (AF) is estimated to be between 1in 3 to 1 in 4 individuals, making it the most common arrhythmia in the world.For persistent AF, rate control drugs with the purpose to affect the conduction properties of the atrioventricular (AV) node are the most common treatment. The drug of choice varies between β-blockers and calcium channel blockers, often
