Declining trust in representative institutions is considered one of the most significant political problems of our time. It is often suggested that democratic innovations—or mechanisms which aim to increase and deepen citizen participation in the political decision-making process—can help reverse this trend. However, empirical research about actual effects of participation on trust is scarce, and

Astaxanthin (AXT) is a reference model of xanthophyll carotenoids, which is used in medicine and food industry, and has potential applications in nanotechnology. Because of its importance, there is a great interest in understanding its molecular properties and aggregation mechanism in water and mixed solvents. In this paper, we report a novel model of AXT for molecular dynamics simulation. The mod

Boron is an attractive high-energy fuel additive. But it could not burn efficiently in practical systems due to its high ignition temperature and slow burning velocity. Finding methods to enhance the combustion of boron is desired. This work focused on the combustion characteristics of boron submicroparticles with and without plasma discharges in a hot environment supported by CH4/N2/O2 flat flame

Two photon photoluminescence (2PPL) from single crystals of methyl ammonium lead bromide (CH3NH3PbBr3, MAPbBr3) is studied. We observe two components in the 2PPL spectra, which we assign to the photoluminescence (PL) from the carrier recombination at the band edge and the recombination due to self-trapping of excitons. The PL Stokes shift of self-trapped excitons is about 100 meV from the band-ga

We demonstrate a femtosecond two-photon laser-induced fluorescence (fs-TPLIF) technique for sensitive CO detection, using a 230 nm pulse of 9 µJ and 45 fs. The advantages of fs-TPLIF in excitation of molecular species were analyzed. Spectra of CO fs-TPLIF were recorded in stable laminar flames spatially resolved across the flame front. A hot band (1, n) together with the conventional band (0, n) o

Background: Methylation quantitative trait loci (mQTLs) are the genetic variants that may affect the DNA methylation patterns of CpG sites. However, their roles in influencing the disturbances of smoking-related epigenetic changes have not been well established. This study was conducted to address whether mQTLs exist in the vicinity of smoking-related CpG sites (±50kb) and to examine their associa

Participation of stakeholders at the local level is evolving as a mechanism to address complex environmental problems, not least water pollution. Participation has been used as a tool for the economic and social empowerment of settlements within the catchment of the Korle lagoon in Ghana, particularly residents of the Old Fadama community that live in proximity to the lagoon. Using direct observat

The MAX IV facility in Lund, Sweden consists of two storage rings for production of synchrotron radiation. The larger 3 GeV ring has been delivering light to the first users since November 2016, while the smaller 1.5 GeV ring is being commissioned. Coupled-Bunch Mode Instabilities (CBMIs) have been observed in both rings, and they have a degrading effect on the beam quality since they increase the

Sofisterna, de första retorikteoretikerna, har inget särskilt gott rykte. Enligt våra uppslagsverk betyder sofism medvetet logiskt felslut. I retoriska handböcker brukar benämningen sofister användas för ett antal retoriskt intresserade lärare och tänkare från antikens Grekland. Det är enligt forskare på området lite oegentligt att tala om sofister, som om det vore någon enhetlig rörelse, vilket d

One classic approach to real-time object detection is to use adaboost to a train a set of look up tables of discrete features. By utilizing a discrete feature set, from features such as local binary patterns, efficient classifiers can be designed. However, these classifiers include interpolation operations while scaling the images over various scales. In this work, we propose the use of real value

Den som har det tryggt och bra flyr inte. Vi flyr från svält, fattigdom och politiskt förtryck. När konferensen om prioriteringar i folkvandringens tid hölls 2016 förväntades mellan 70000 och 140000 flyktingar komma till Sverige. Några av dem hade varit med om hemskheter som nog flera av oss i Sverige har svårt att föreställa sig. Många var/är i stort behov av vård på grund av fysisk eller psykisk

Type 2 diabetes (T2D) is associated with deterioration of brain structure and function. Here, we tested the hypothesis that T2D induces a reorganization of the brain metabolic networks that support brain function. For that, alterations of neuronal and glial energy metabolism were investigated in a T2D model, the Goto-Kakizaki (GK) rat. (13)C magnetic resonance spectroscopy in vivo at 14.1 T was us

Environmental stress can interact with genetic predisposition to increase the risk of developing psychopathology. In this work, we tested the hypothesis that social isolation stress interacts with impaired glutathione synthesis and have cumulative effects on the neurochemical profile of the frontal cortex. A mouse model with chronic glutathione deficit induced by knockout (-/-) of the glutamate-cy

Detta är den fjärde skriften i en serie som handlar om vetenskap och beprövad erfarenhet. Med hjälp av sakkunniga inom olika områden försöker vi kartlägga begrep- pets betydelse och användning inom olika verksamhetsområden. Tidigare häften har handlat om medicin, juridik och skola.Den som läst dessa häften kan nu skönja vissa mönster. Begreppet vetenskap och beprövad erfarenhet förstås på olika sä

A better understanding of BOLD responses stems from a better characterization of the brain's ability to metabolize glucose and oxygen. Non-invasive techniques such as functional magnetic resonance spectroscopy (fMRS) have thus been developed allowing for the reproducible assessment of metabolic changes during barrel cortex (S1BF) activations in rats. The present study aimed at further exploring th
