A photochemical reactor for studies of atmospheric kinetics and spectroscopy has been built at the Copenhagen Center for Atmospheric Research. The reactor consists of a vacuum FTIR spectrometer coupled to a 100 L quartz cylinder by multipass optics mounted on electropolished stainless steel end flanges, surrounded by UV-A, UV-C and broadband sun lamps in a temperature-controlled housing. The combi
The kinetic isotope effects in the reactions of CHCl3, CDCl 3, and 13CHCl3 with Cl, OH, and OD radicals have been determined in relative rate experiments at 298 ± 1 K and atmospheric pressure monitored by long path FTIR spectroscopy. The spectra were analyzed using a nonlinear least-squares spectral fitting procedure including line data from the HITRAN database and measured infrared spectra as ref
The “nativisation” of welfare provision implicitly accepts the SD’s redefinition of refugees as undeserving others and gives credence to its chauvinistic welfare policies. Not only does the restriction of entitlements to non-native Swedes effectively constitute a symbolic bordering practice that circumscribes a restrictive and nativistic understanding of national identity, where solidarity is rese
In a gas turbine engine, the low pressure turbine (LPT) and the outlet guide vane (OGV) part are connected in the rear part. The outlet nozzle is designed as a contracted part to increase the ejection velocity and a pocket cavity (PC) is formed at this location. In this research work, the effects of the locations of the PC on the downstream endwall with a symmetrical vane (SV) are investigated and
This study aims to investigate the environmental, operational and economic performance of the methanol partially premixed combustion concept at slow speed operation of a ship to find a solution for the shipping emission effect on the coastal settlements while do not increase the risk and expense of the engine operation on the ships. The experimental study was done with partially premixed combustio
Hypoglycaemia is common in both type 1 and type 2 diabetes and has both acute and long-term consequences. Therefore, a key to proper glucose-lowering therapy in diabetes is to avoid or prevent hypoglycaemia. Incretin therapy (DPP-4 inhibitors and GLP-1 receptor agonists) offers an advantage in this respect, because it reduces glucose with a low risk of hypoglycaemia, both in monotherapy and in com
The mechanism of stabilizing a turbulent premixed methane-air flame using warm filamentary plasma is investigated by using laser diagnostics. First, stabilization of a turbulent jet flame is demonstrated in a setup using a pin-to-pin plasma discharge. The coupled plasma-flame structures were visualized utilizing planar laser-induced fluorescence (PLIF) of formaldehyde (CH2O) and methylidyne radica
Pool boiling performance of NOVEC-649 was experimentally studied on microporous surfaces prepared by an electrochemical deposition method. Microporous structures contribute to large surface roughness values and provide large quantities of cavities ranging from several hundreds of nanometers to several microns for bubble nucleation. The results show that a maximum enhancement of 600% in heat transf
Changes in vegetation phenology are among the most sensitive biological responses to global change. While land surface phenological changes in the Northern Hemisphere have been extensively studied from the widely used long-term AVHRR (Advanced Very High Resolution Radiometer) data, current knowledge on land surface phenological trends and the associated drivers remains uncertain for the tropics. T
Reduced chemical kinetic mechanisms are essential for atmospheric chemistry modeling where the use of explicit kinetic schemes is too computationally demanding. By tailoring mechanisms to specific cases, the size of the mechanism can be kept small, without significant loss of accuracy in predictions of selected species’ concentrations. In the present work, we present small kinetic mechanisms tailo
Cancer-associated gene fusions resulting in chimeric proteins or aberrant expression of one or both partner genes are pathogenetically and clinically important in several hematologic malignancies and solid tumors. Since the advent of different types of massively parallel sequencing (MPS), the number of identified gene fusions has increased dramatically, prompting the question whether they all have
The aim of this study was to find a solvent to replace N-methyl-2-pyrrolidone (NMP) in CO2 absorption systems containing the amine 2-amino-2-methyl-1-propanol (AMP), in order to reduce the health risks associated with handling, as NMP is reproductively toxic. Seven organic solvents were investigated: dimethyl sulfoxide (DMSO), 3-(dimethylamino)propionitrile (3DMAPN), 1-pentanol (1 P), propylene ca
Lean premixed combustion (LPC) is a promising technology for low-NOx emission, while it increases the risk of blowoff at the same time. Experiments and Large Eddy Simulations (LES) on swirl stratified lean-premixed CH4/air flames were performed to study the differences between the stable and near blowoff flame. The flow fields and instantaneous flame structures were measured by simultaneous Partic
As a result of increasing bacterial resistance against antibiotics, we are facing an emerging health crisis, in which ‘simple’ infections may no longer be treatable. One class of molecules attracting interest in this context is antimicrobial peptides (AMPs), and considerable research efforts have been directed to identifying selective and potent AMPs. In addition, since in vivo delivery of AMPs is
Heat tolerance increases at higher acclimation temperatures in D. melanogaster, but not in D. subobscura. The two species represent separate lineages of the subgenus Sophophora of Drosophila with contrasting tropical African and temperate Palearctic evolutionary histories. D. melanogaster has five copies of the inducible hsp70 gene distributed in two clusters, named A (with two copies) and B (thre
Following the 7.5-Mw earthquake that occurred on 28 September 2018, a series of field surveys were performed to further understand the impacts of the resulting tsunami. Tsunamis initiated by strike-slip earthquakes are rare. Other factors are suspected to have contributed to this unusual tsunami. One of these factors was the subaerial landslides around Palu Bay, which were observed at several loca
Adequate reliability of measurement is a precondition for investigating individual differences and age-related changes in brain structure. One approach to improve reliability is to identify and control for variables that are predictive of within-person variance. To this end, we applied both classical statistical methods and machine-learning-inspired approaches to structural magnetic resonance imag
A total of 16 global chemistry transport models and general circulation models have participated in this study; 14 models have been evaluated with regard to their ability to reproduce the near-surface observed number concentration of aerosol particles and cloud condensation nuclei (CCN), as well as derived cloud droplet number concentration (CDNC). Model results for the period 2011-2015 are compar
