Probe thermometry with continuous measurements
Temperature estimation plays a vital role across natural sciences. A standard approach is provided by probe thermometry, where a probe is brought into contact with the sample and examined after a certain amount of time has passed. In situations where, for example, preparation of the probe is non-trivial or total measurement time of the experiment is the main resource that must be optimized, contin

The effect of temperature and relative humidity on secondary organic aerosol formation from ozonolysis of Δ3-carene
This study investigates the effects of temperature and relative humidity (RH) on the formation of secondary organic aerosol (SOA) from Δ3-carene, a prevalent monoterpene in boreal forests. Dark ozonolysis experiments of 10 ppb Δ3-carene were conducted in the Aarhus University Research on Aerosol (AURA) atmospheric simulation chamber at temperatures of 0, 10, and 20 °C. Under dry conditions (RH < 2

Patients with volume-loaded right ventricle - quantification of left ventricular hemodynamic response to intervention measured by noninvasive pressure-volume loops
Volume loading of the right ventricle (RV) in patients with atrial septal defect (ASD) and patients with repaired Tetralogy of Fallot (rToF) affects the pumping mechanics of the left ventricle (LV). Intervention of the lesion will relieve the RV volume load however quantifiable impact on exercise capacity, arrhytmias or death are limited. A possible explanation could be remaining effects on the fu

Against the turning away: : Understanding the relationships of bystander motivation and behaviors to school bullying
Forskning om mobbning i skolan har ägnat avsevärd uppmärksamhet åt att undersöka vilken roll åskådare (elever som bevittnar mobbning eller vet att den pågår) spelar i att påverka antalet mobbningsfall. Omfattande forskningsfynd har visat att ingripande från kamrater är väsentligt för att minska mobbningsbeteenden och följaktligen har efterföljande studier sökt avgöra vilka faktorer som bidrar tillResearch on school bullying has devoted a considerable amount of attention to investigating the roles of bystanders – the students who witness bullying or know that it is occurring – in bullying episodes. Numerous findings have shown that peer intervention is essential for reducing bullying behaviors; consequently, subsequent studies have examined which factors contribute to increasing the number
Adaptive design of tipping bucket flow meters for continuous runoff measurement
Introduction: Runoff measurement and monitoring is a laborious, timeconsuming,and costly task. Additionally, common runoff monitoring usually primarily provide water level, requiring information on the stage-discharge relation. Automatic equipment such as flow meter tipping bucket (TB) is a potential option to simplify and provide continuous runoff monitoring in small catchments. However, a proper
Calibration and error investigation of large tipping bucket flow meters
Inherent errors in tipping bucket flow meters may limit monitoring data reliability. In this work, we perform the static and dynamic calibration of four large tipping buckets, apply different regression curves and investigate the possible measurement error sources. The volumetric capacity (static calibration) of each piece of equipment was determined. They were tested (dynamic calibration) under t
