Technical developments for the detection of formaldehyde using laser-induced fluorescence were presented. A technique for simultaneous detection of formaldehyde and OH using one laser system was presented. The combined formaldehyde and OH technique was applied in laboratory flames and a small spark-ignition engine. The iodine measurement was performed in a cell using the second harmonic of the sin

This paper presents technical developments for the detection of formaldehyde (CH2O) using laser-induced fluorescence. The easily accessible third harmonic of the Nd:YAG laser at 355 nm was used for excitation of formaldehyde. In order to investigate potential background fluorescence, e.g., from large molecules such as polyaromatic hydrocarbons, special attention was paid to investigating the possi

Objectives: In this nationwide cohort study in a Scandinavian setting, we aimed to investigate the magnitude of association between flucloxacillin use and drug-induced liver injury (DILI). Methods: Nationwide cohort study among adults in Sweden, 2006–2018, was conducted. Register data on filled prescriptions, patient characteristics, co-medications, and DILI were linked. All filled prescriptions f

Coherent multidimensional spectroscopy (CMDS) is the most complete nonlinear optical technique based on the interaction of multiple short laser pulses with matter. It has grown to play a significant role in studies of optoelectronic materials and pigment protein complexes. In this work we apply CMDS to investigate electronic excitations and their dynamics in semiconductor nanocrystals, so called q

Mid-infrared polarization spectroscopy was applied to detect HCl at trace level in an atmospheric pressure premixed H2/O2/Ar flame with chloroform seeding. Detection sensitivity and potential interference from water lines was investigated.

Investigations on remote temperature sensing of yttria stabilized zirconia (YSZ) thermal barrier coatings (TBCs) at the surface and at the bond-coat/top-coat interface were carried out. Using Y2O3:Eu thermographic phosphor as an embedded temperature sensing layer, sub-surface temperature probing through 300 μm of atmospheric plasma sprayed YSZ is demonstrated. The Y2O3:Eu thermographic phosphor di

The Augustan poet Ovid (43 BC – AD 17/18) is mentioned by Seneca the elder for his oratorical skills as a school boy. If we are to believe Seneca, Ovid excelled to such a degree that he even surpassed his teachers. He took special interest in exercises concerning ethos, and is said to have transferred what he learned into his own verse. The influence from rhetorical training is indeed visible in O

An ethopoeia is an imagined speech assigned to a certain character. As a rhetorical exercise it is known from the progymnasmata of Theon, Hermogenes, Aphthonius and Nicolaus as well as contemporary rhetorical theorists. The purpose of the exercise was to teach the student the appropriate use of ethos and pathos for the assigned character. The paper will present the function of the ethopoeia as a p

The "International Society for Heart and Lung Transplantation Guidelines for the Evaluation and Care of Cardiac Transplant Candidates-2024" updates and replaces the "Listing Criteria for Heart Transplantation: International Society for Heart and Lung Transplantation Guidelines for the Care of Cardiac Transplant Candidates-2006" and the "2016 International Society for Heart Lung Transplantation Lis

Cholesterol is an essential membrane component enriched in plasma membranes, growth cones, and synapses. The brain normally synthesizes all cholesterol locally, but the contribution of individual cell types to brain cholesterol metabolism is unknown. To investigate whether cortical projection neurons in vivo essentially require cholesterol biosynthesis and which cell types support neurons, we have

Introduction: The purpose of this study was to experimentally investigate the effects of changes in both quantity and quality of use of social networking sites (SNS) on measures of anxiety, depression, stress, self-esteem, loneliness, problematic social media use, and present focused awareness. Method: Participants were randomly assigned to three different conditions: reducing SNS time to 30 minut

Background: Participants in epidemiological cohorts may not be representative of the full invited population, limiting the generalizability of prevalence and incidence estimates. We propose that this problem can be remedied by exploiting data on baseline participants who refused to participate in a re-examination, as such participants may be more similar to baseline non-participants than what base
