Today's petrochemical industry relies on fossil hydrocarbons, not only for energy purposes but also as feedstock. This use of fossil materials is being challenged by the European Union's target to achieve climate neutrality by 2050. The most affected region in Europe is the cross-border region between Antwerp, Rotterdam and the Rhine-Ruhr area in western Germany, an interconnected petrochemical me
A series of molecular alloys of 1,2,4,5-tetrabromobenzene and 1,2,4,5-tetrachlorobenzene with varying compositions were prepared in an attempt to obtain jumping crystals with adjustable temperature of thermosalient phase transition. Molecular alloys were studied with a combination of thermal and structural techniques (DSC, SCXRD, XRPD, hot-stage microscopy). Alloys with a high 1,2,4,5-tetrabromobe
The European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. a rotating Tungsten disk, it will deliver high-flux neutron beams to multiple beamlines at which scientific experiments will be conducted in many scientific disciplines.To simulate the proton beam and for crea
The first generation of ELT instruments includes an optical-infrared high resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion Echelle Spectrograph).ANDES consists of three fibre-fed spectrographs ([U]BV, RIZ, YJH) providing a spectral resolution of ∼100,000 with a minimum simultaneous wavelength coverage of 0.4-1.8 µm with the goal of extending
We consider differential Riccati equations (DREs). These equations arise in many areas and are very important within the field of optimal control. In particular, DREs provide the crucial link between the state and the optimal input in the solution of linear quadratic regulator (LQR) problems. For the approximation of the solutions to DREs we consider the recently introduced splitting methods, wit
Differences in national legislations can affect the international competitiveness of an industry. For example, stringent EU regulations on animal welfare and environmental protection are often said to be a cost disadvantage for EU producers competing on the global market. However, in recent years, powerful retailers and food processors have started to impose requirements on downstream producers th
The meshless radial point interpolation method (RPIM) in frequency domain for electromagnetic scattering problems is presented. This method promises high accuracy in a simple collocation approach using radial basis functions. The treatment of high-order non-reflecting boundary conditions for open waveguides is discussed and implemented up to fourth-order. RPIM allows the direct calculation of high
Objective Although important treatment decisions are made in the Emergency Department (ED), conversations about patients’ goals and values and priorities often do not occur. There is a critical need to improve the frequency of these conversations, so that ED providers can align treatment plans with these goals, values, and priorities. The Serious Illness Conversation Guide has been used in other c
The polar region is experiencing one of the most rapid environmental changes driven by atmospheric warming, and feedbacks within the cryosphere. Under such a setting, it is crucial to understand the biogeochemical cycling of the nutrient silicon (Si) in the high latitudes, which is regulating the nutrient supply to polar ecosystems, and is linked to the global carbon cycle via diatom production. H
The purpose of the study was to explore the role of the physical environment for creative employees. The results are based on interviews with office-working digital artists. The physical work environment was considered to offer three types of support for creative work for the participants: functional, psychosocial, and inspirational. Creative processes would find better breeding ground if function
The Ordovician Period includes two major macroevolutionary events: the Great Ordovician Biodiversification Event (GOBE) and the Late Ordovician Mass Extinction (LOME), alongside a fundamental climate transition from a greenhouse to an icehouse state. Although both biological events occurred during relatively short-term global cooling conditions, their starkly contrasting biotic responses remain po
Problematic internet use (PIU) has been linked to adverse outcomes in adolescence, but its association with child-to-parent violence (CPV) has rarely been examined. This study investigated whether problematic social media use and problematic gaming were associated with CPV in a school-based sample of Swedish adolescents and young adults. In bivariate analyses, both PIU domains showed dose-responseProblematic internet use (PIU) has been linked to adverse outcomes in adolescence, but its association with child-to-parent violence (CPV) has rarely been examined.

For developing and implementing innovations that improve a firm's environmental performance ('eco-innovation'), external knowledge and technologies, and hence the openness of a firm, are crucial. This paper analyses the factors that drive eco-innovation in firms, drawing special attention to the firm's ability to implement new ways of working within the organisation ('workplace innovation'). Based
Insertion of metals into various tetrapyrroles is catalysed by a group of enzymes called chelatases, e.g. nickel, cobalt, magnesium and ferrochelatase. It has been proposed that catalytic metallation includes distorting the porphyrin substrate by the enzyme towards a transition state-like geometry in which at least one of the pyrrole rings will be available for metal chelation. Here, we present a
An experiment has been performed to search for superdeformed (SD) states in Dy-149,Dy-150. While no evidence for discrete superdeformed states has been observed, a superdeformed ridge with a separation of Delta E-gamma=52 keV with a total intensity of 1.8+/-0.5% that of Dy-150 has been observed. An upper limit of 0.8% (0.9%), of the intensity of Dy-150 (Dy-149), is placed for observation of the mo
