Internal traverse grinding (ITG) using electroplated cBN tools in high-speed grinding conditions is a highly efficient manufacturing process for bore machining in a single axial stroke. However, process control is difficult. Due to the axial direction of feed, changes in process normal force and thus radial deflection of the tool and workpiece spindle system, lead to deviations in the workpiece co
Candida maltosa was cultivated in the liquid phase of residual brewing yeast, a major brewery residue, to produce biomass and biofilm. Using response surface methodology, the effect of two variables at two different levels was investigated. The independent variables were agitation speed (at 100 and 200 rpm), and aeration (at 1 and 3 L min−1). Aeration was identified to be important for the product
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)
