To map out the state of the art of comparative studies of Internet use and recognize the contributions and shortcomings in the current literature, we have used a four-dimension framework to conduct a review of journal articles indexed in the Social Sciences Citation Index (SSCI) in the field of communication studies in the Web of Science core collection between 1969 and 2019. Our findings describe
Plastics play an essential role in modern society, but also lead to significant impacts on the environment and climate. Reducing such impacts while retaining the usefulness of plastics requires a shift towards a more circular and sustainable plastics system. This report tells the story of plastics, and their effect on the environment and climate, and looks at their place in a European circular eco
In the literature on Swedish labour market history, it is commonly accepted (Westerståhl 1945, Nycander 2008) that the Swedish state in the late nineteenth and early twentieth centuries was unique in its abstention from anti-union, anti-strike policy. While in other European countries the conflict between employers and workers led to state repression of unions and strikes, the Swedish state was ne
The article addresses the broader relationships between seaweed and algae as a marine resource, destination development, and sustainability. In many European countries, an industry around seaweed has emerged, ranging from high-end restaurants that provide their customers with local, seasonal and sustainableingredients, to entrepreneurs offering “harvest your own seaweed”-tours. In this explorative
The digital information age has changed global tourism in profound ways. Information and Communication Technologies (ICT) are pervasive, and they have become inextricably linked with contemporary consumer cultures. ICTs represent affordances: to apprise, plan, order, network, socialize, stream, transact and rate. These are remunerated with concessions in the form of consumer data that is used to d
Is the 'natural resource curse' destiny? Are different ways to link natural resources and economic development? Using two particular regions as case studies, this edited collection examines the divergent development paths of natural resource rich countries over the past two centuries. Bolivia, Chile and Peru are neighbour states with a common history and are globally known by their mining endowmen
A finite element method is developed for the study of elastic wave propagation in layered ground environments. The formulation is based on a spectral finite-element approach using a mixture of high-order element shape functions and wave solutions. The numerical method provides solutions to vibration transmission on and within layered elastic waveguides. Examples of its use include the theoretical
Electrical impedance tomography (EIT) is a noninvasive imaging modality, where imperceptible currents are applied to the skin and the resulting surface voltages are measured. It has the potential to distinguish between ischaemic and haemorrhagic stroke with a portable and inexpensive device. The image reconstruction relies on an accurate forward model of the experimental setup. Because of the rela
Cells of the exocrine pancreas produce digestive enzymes potentially harmful to the intestinal mucosa. Dopamine has been reported to protect against mucosal injury. In looking for the source of dopamine in the small intestine, we found that the duodenal juice contains high levels of dopamine and that the pancreas itself has a high dopamine [and dihydroxyphenylalanine (dopa)] content that does not
As the widespread pessimism about African agriculture has receded, policies for a green revolution in Africa are again called for. This study explores the presence of a national-level green revolution in Ethiopia and finds that an Ethiopian green revolution has taken place since the mid-1990s, mainly among staple-growing smallholders in agroecologically favourable areas and that the state has play
Streptococcus agalactiae, also known as group B Streptococcus (GBS), is the major cause of neonatal sepsis in humans. A critical step to infection is adhesion of bacteria to epithelial surfaces. GBS adhesins have been identified to bind extracellular matrix components and cellular receptors. However, several putative adhesins have no host binding partner characterised. We report here that surface-
Background: Patients with wake-up ischemic stroke who have evidence of salvageable tissue on advanced imaging can benefit from intravenous thrombolysis. It is not known whether patients who do not fulfil such imaging criteria might benefit from treatment, but studies indicate that treatment based on non-contrast CT criteria may be safe. Tenecteplase has shown promising results in patients with acu
We study the codimension-one and -two bifurcations of the Ornstein-Zernike equation with hypernetted chain (HNC) closure with Lennard-Jones intermolecular interaction potential. The main purpose of the paper is to present the results of a numerical study undertaken using a suite of algorithms implemented in MATLAB and based on pseudo arc-length continuation for the codimension-one case and a Newto
BACKGROUND: Small intestinal neuroendocrine tumors (SI-NETs) are difficult to diagnose in the early stage of disease. Current blood biomarkers such as chromogranin A (CgA) and 5-hydroxyindolacetic acid (5-HIAA) have low sensitivity and specificity. This is a first pre-planned interim analysis (NORDIC non-interventional, exploratory, EXPLAIN study (NCT02630654)). Its objective is to investigate if
Organised on the 16 November 2020, the roundtable on “Sharing Cities – Shaping Tomorrow” focused on sharing insights and ideas on the future of sharing in our cities and communities. The roundtable gathered over 40 people from around world and formed part of the Smart City Live Conference. This report pulls together the conversations at the roundtable and distils the key findings.
Alternative ways to prevent and treat infectious diseases are needed. Previously, we identified a fungal peptide, NZX, that was comparable to rifampicin in lowering M. tuberculosis load in a murine tuberculosis (TB) infection model. Here we assessed the potential synergy between this cationic host defence peptide (CHDP) and the current TB drugs and analysed its pharmacokinetics. We found additive
This thesis presents the simulations of and experiments with the so-called CECOST burner. The CECOST burner is a gas turbine model combustor equipped with an axial swirler and placed in a laboratory for the lean premixed turbulent combustion of a range of fuels at atmospheric pressure. The operation with natural gas, methane, hydrogen-enriched methane and syngas from black-liquor gasification was
