Dimethyl sulfide (DMS) is the dominant biogenic sulfur compound in the ambient marine atmosphere. Low-volatility acids from DMS oxidation promote the formation and growth of sulfur aerosols and ultimately alter cloud properties and Earth's climate. We studied the OH-initiated oxidation of DMS in the Aarhus University Research on Aerosol (AURA) smog chamber and the marine boundary layer (MBL) with

The cognitive model of obsessive-compulsive disorder (OCD) posits that dysfunctional cognitive beliefs are crucial to the onset and maintenance of OCD; however, the relationship between these cognitive beliefs and the heterogeneity of OCD symptoms in children and adolescents remains unknown. We examined how the major belief domains of the cognitive model (inflated responsibility/threat estimation,

During the last ice age, the Northern Hemisphere experienced a series of abrupt millennial-scale climatic changes linked to variations in the strength of the Atlantic Meridional Overturning Circulation and sea-ice extent. However, our understanding of their impacts on decadal-scale climate variability in central Europe has been limited by the lack of high-resolution continental archives. Here, we

Den här avhandlingen har som syfte att bidra till att täcka kunskapsluckor om hur tilläggssvårigheter vid attention deficit hyperactivity disorder (ADHD) hos barn förändras och om dessa har ett samband med hur ADHD-problematiken utvecklas under 3 års tid. ADHD är en utvecklingsrelaterad kognitiv funktionsnedsättning som debuterar hos barn och unga, 12 år eller yngre, genom höga nivåer av ouppmärksClarification on how cognitive, executive and emotional functioning contribute to symptom reduction or improved function in childhood attention deficit hyperactivity disorder (ADHD) is needed to find additional treatment methods. The clinical utility of continuous performance test (CPT) (Conners’ CPT-II, QbTest) to complement rating scales in diagnostic assessments and treatment evaluations (QbTes

Amino acid starvation is sensed by Escherichia coli RelA and Bacillus subtilis Rel through monitoring the aminoacylation status of ribosomal A-site tRNA. These enzymes are positively regulated by their product-the alarmone nucleotide (p)ppGpp-through an unknown mechanism. The (p)ppGpp-synthetic activity of Rel/RelA is controlled via auto-inhibition by the hydrolase/pseudo-hydrolase (HD/pseudo-HD)

Ziel der Arbeit ist es, eine Analyse sozio-technischer Energieszenarien durchzuführen, um herauszufi nden, inwieweit soziologische Dimensionen beziehungsweise Konzepte in diesem enthalten sind und welche dabei am häufi gsten aufgegriff en werden. In der vorliegenden Arbeitist eine qualitati ve Inhaltsanalyse dieser Energieszenarien nach Mayring durchgeführt worden.Dabei bestand der theoreti sche H

Our society is built upon energy – we need energy for its functioning and development.However, given our current dependence on non-renewable energy sources, a more sustainableuse needs to be achieved. A new tool of science and sustainability communication isvisualization to increase public awareness and understanding of energy issues.The aim of the study was to examine how energy data can be visua
