Directed relation graph with error propagation (DRGEP) method combined with extensive validation for 0D, 1D and 2D CFD modeling supported by sensitivity and Rate-Of-Production (ROP) analyses are implemented for comparative study of detailed and reduced kinetic mechanisms for CH 4
Animals are thought to use achromatic signals to detect small (or distant) objects and chromatic signals for large (or nearby) objects. While the spatial resolution of the achromatic channel has been widely studied, the spatial resolution of the chromatic channel has rarely been estimated. Using an operant conditioning method, we determined (i) the achromatic contrast sensitivity function and (ii)
Top marginal rates in income taxes increased significantly during the two World Wars in most Western countries, which points towards increases in their progressivity. We argue, however, that this war-related effect is less clear-cut than previously thought: wartime inflation could have exerted a counteracting impact by pushing citizens into higher tax brackets, including new individuals from the b
Poor air quality is a leading contributor to the global disease burden and total number of deaths worldwide. Humans spend most of their time in built environments where the majority of the inhalation exposure occurs. Indoor Air Quality (IAQ) is challenged by outdoor air pollution entering indoors through ventilation and infiltration and by indoor emission sources. The aim of this study was to unde
The Baltic Sea is one of the most eutrophied seas in the world, facing challenges with both hypoxia and algae blooms. In this study we analyse the effect of using different fishery policy instruments to reduce nutrient loads by removing fish biomass from the ecosystem. The study covers Danish, Finnish and Swedish pelagic fisheries. We distinguish between a private optimum maximising the net presen
The postwar condition – the period where war is over yet the socio-political ordering of any given postwar entity remains contested and an unchallenged peace has still to be reached – is inherently spatial. This spatiality, however, has yet be fully addressed in theoretical and analytical terms, meaning that we neither understand it in its entirety nor have the tools with which to explore it thoro
Most diurnal birds have cone-dominated retinae and tetrachromatic colour vision based on ultra-violet/violet-sensitive UV/V cones expressing short wavelength-sensitive opsin 1 (SWS1), S cones expressing short wavelength-sensitive opsin 2 (SWS2), M cones expressing medium wavelength-sensitive opsin (RH2) and L cones expressing long wavelength-sensitive opsin (LWS). Double cones (D) express LWS but
Many insects have triplets of camera type eyes, called ocelli, whose function remains unclear for most species. Here, we investigate the ocelli of the bumblebee, Bombus terrestris, using reconstructed 3D data from X-ray microtomography scans combined with computational ray-tracing simulations. This method enables us, not only to predict the visual fields of the ocelli, but to explore for the first
Identifying and characterizing young stars in the Solar neighbourhood is essential to find and describe planets in the early stages of their evolution. This work seeks to identify nearby young stars showing a lithium 6708 Å absorption line in the GALAH survey. A robust, data-driven approach is used to search for corresponding templates in the pool of 434 215 measured dwarf spectra in the survey. I
This study examines the influences of national contexts on crisis attribution to address the recent appeal for a more contextually sensitive perspective in crisis communication research. Specifically, this study revisits the Situational Crisis Communication Theory (SCCT) in the Chinese context by taking an online discussion on Weibo about a high-profile homicide in a McDonald’s restaurant as the c
Amphipyrinae have long been a catchall taxon for Noctuidae, with most members lacking discernible morphological synapomorphies that would allow their assignment to one of the many readily diagnosable noctuid subfamilies. Here data from seven gene regions (> 5500 bp) for more than 120 noctuid genera are used to infer a phylogeny for Amphipyrinae and related subfamilies. Sequence data for 57 amphipy
Polyamines are small aliphatic cationic molecules synthesized via a highly regulated pathway and involved in general molecular and cellular phenomena. Both mammalian cells and microorganisms synthesize polyamines, and both sources may contribute to the presence of polyamines in the circulation. The dominant location for microorganisms within the body is the gut. Accordingly, the gut microbiota pro
Background: This preclinical study in humans was designed to selectively induce delayed nociceptive pain responses to individually titrated laser stimulation, enabling separate bedside intensity scoring of both immediate and delayed pain. Methods: Forty-four (fourteen female) healthy volunteers were subjected to repeated nociceptive dermal
Background: Bariatric surgery is considered to be the most effective method of weight loss today. The aim of the present Swedish study, which was performed in a country that has universal health care, was to investigate if there is an association between socioeconomic factors and bariatric surgery by taking body mass index (BMI) into accoun
Studies on risk factors for penile intraepithelial neo-plasia have been small in size, have not distinguished penile intraepithelial neoplasia from invasive cancer, and have relied on self-reported information. This study investigated risk factors for penile intraepithelial neoplasia in a cohort of 580 penile intraepithelial neoplasia cases and 3,436 controls using information from 7 Swedish regis
