The world faces major climate challenges and extensive efforts need to be taken to combat this issue. Replacing fossil-derived fuels and chemicals with renewables are one important step on the way. Hydrogen has a great potential as a renewable energy carrier for the transport sector and as a green chemical for the industry. Today, the production of hydrogen stems primarily from fossil resources. A

The First World War is usually conceived as a turning point in the history of migration policy. Before the war, borders were largely open, passports were in most places abolished, and the movement of people as well as capital and traded goods was understood through an optimistic and liberal institutionalist lens. At the outbreak of the war, states reinstated passport controls, presumably as a temp

A method was developed, which drives the selection of appropriate solar control mechanisms based on theanalysis of overheating due to solar heat gains. The aim of the method is to maintain adequate thermalcomfort levels in highly glazed spaces. Two thermal comfort models, Predicted Mean Vote and AdaptiveModel, were chosen to set the thermal comfort boundaries included in the method. Moreover, in o

The 15 and 28 GHz frequency bands have been identified as interesting candidates for future 5G cellular communication systems. In this paper, based on ray-tracing simulations, we investigate the channel capacities at 15 and 28 GHz for a number of different array processing techniques, including beamforming, spatial multiplexing, and two types of hybrid beamforming. This is done for an 8x32 multipl

Parkinson's disease dementia (PDD) has become an increasing area of research as treatments for the motor features of Parkinson's disease (PD) have improved and the population of patients with PD grows and ages. If predictors could be used to identify a sub-population of patients at risk of developing an early PDD then research into its neuropathological basis and treatment could be more effectivel

Nano and micro structured thin (μ m-scale) foils were designed, fabricated and irradiated with the high intensity laser system operating at LLC (Lund Laser Centre, Sweden) in order to systematically study and improve the main proton beam parameters. Nano-spheres deposited on the front (laser irradiated) surface of a flat Mylar foil enabled a small enhancement of the maximum energy and number of th

The increased impact from fluctuating energy sources like wind and photovoltaics significantly affects the operational regime of conventional power plants. In the near future, even former base load power plants such as the large-scale lignite plants in Germany will need to start and shut down to balance the electricity system. As frequent starts were not in the focus of optimisation in the past, a

STUDY QUESTION Does an intensive weight reduction programme prior to IVF increase live birth rates for infertile obese women? SUMMARY ANSWER An intensive weight reduction programme resulted in a large weight loss but did not substantially affect live birth rates in obese women scheduled for IVF. WHAT IS ALREADY KNOWN Among obese women, fertility and obstetric outcomes are influenced negatively wit

Although differentiated cells normally retain cell-type-specific gene expression patterns throughout their lifetime, cell identity can sometimes be modified or reversed in vivo by transdifferentiation, or experimentally through cell fusion or by nuclear transfer. To examine the epigenetic changes that are required for the dominant conversion of lymphocytes to muscle, we generated heterokaryons bet

Following the EU declaration from 2016 on schools as the most crucial places for societal change needed in order to strengthen democracy, this chapter discusses Nordic music education and music education research within the context of shared challenges in times of rapid demographic changes. Resting on emerging results from the authors’ research projects, the first theme to be discussed is music ed

We report on the synthesis of vertical InP nanowire arrays on (001) InP and Si substrates using template-assisted vapour–liquid–solid growth. A thick silicon oxide layer was first deposited on the substrates. The samples were then patterned by electron beam lithography and deep dry etching through the oxide layer down to the substrate surface. Gold seed particles were subsequently deposited in the

The subgrade is the top surface of a roadbed upon which the pavement structure is constructed. The purpose is to provide a platform for construction of the pavement and to support the pavement without unwanted deflection that would reduce its performance. For those reasons subgrade bearing capacity have to be investigate during the construction process as a quality control, based on the design res

The N400 has been seen to be larger for concrete thanabstract words, and for pseudowords than real words. Using a word vectoranalysis to calculate semantic associates (SA), as well as ratings foremotional arousal (EA), and a measure of orthographic neighbourhood (ON), thepresent study investigated the relation between these factors and N400 amplitudes during a lexical decision task usingSwedish wo

The aim of this study is to explore the possibility of identifying speaker stance in discourse, provide an analytical resource for it and an evaluation of the level of agreement across speakers in the area of stance-taking in discourse. We explore to what extent language users agree about what kind of stances are expressed in natural language use or whether their interpretations diverge. In order

Is the Armenian Genocide a strictly historical matter? If that is the case, why is it still a topical issue, capable of causing diplomatic rows and heated debates? The short answer would be that the century old Armenian Genocide is much more than a historical question. It emerged as a political dilemma on the international arena at the San Stefano peace conference in 1878 and has remained as such

As farms are getting bigger with more animals, less manual supervision and attention can be given the animals on both group and individual level. In order not to jeopardize animal welfare, automated supervision is in some way already in use. Function and control of ventilation is already in use in modern pig stables, e.g. by the use of sensors for temperature, relative humidity and malfunction con

This study investigates how communication consultants struggle to reconstruct their professional role in the digital media landscape. The extant literature on professional roles in public relations has a tendency to render roles as static pregivens. Therefore, the purpose of this study is to contribute conceptually and empirically to role research by focusing on the process of “role-making” and ho

We consider the problem of designing demodulators for channels with memory that use reduced-size trellis descriptions for the received signal. We assume an overall iterative receiver, and for the parts of the signal not covered by the trellis description, we use interference cancellation based on the soft information provided by the outer decoder. In order to reach a trellis description, a linear
