A short perspective paper.

Migration played a central role in industrialisation by reallocating labour from the countryside to urban areas and centres of manufacturing where it was in high demand, and better remunerated, with implications for economic growth and individual well-being. We investigate the labour market performance of internal migrants in Sweden around the turn of the last century; a period of industrialisatio

The threat that solar storms pose to our ever-modernizing society has gathered significant interest in the recent past. This is partly due to the discoveries of large peaks in the content of cosmogenic radionuclides such as radiocarbon (14C) in tree rings and beryllium-10 (10Be) and chlorine-36 (36Cl) in ice cores that were linked to extreme solar storms dated to the past millennia. To better asse

Device-aided therapies, including levodopa-carbidopa intestinal gel infusion, apomorphine subcutaneous infusion, and deep brain stimulation, are available in many countries for the management of the advanced stage of Parkinson’s disease (PD). Currently, selection of device-aided therapies is mainly focused on patients’ motor profile while non-motor symptoms play a role limited to being regarded as

Companies enjoy increasingly extensive protection of their fundamental right to conduct business under EU law. This article will examine whether this protection is justified by reference to the foundational value of human freedom. In other words, does the way in which EU law protects the fundamental rights of companies to conduct business promote the freedom of individuals human beings within the

Combustion of methane with air in the presence of hydrogen chloride was studied in a turbulent jet-stirred burner. The reaction was monitored by in situ mass spectometry and the ratio of Cl2 2HCl intensities was measured as a function of equivalence ratio (Φ). For values of Φ = 1.25 - 0.5 (fuel rich to fuel lean flames) the ratio of Cl2 2HCl intensities was close to zero. For values of Φ < 0.5 the

The response of mortality to short-term changes in real wages is analyzed here not just in its own right but more particularly as an indicator of long-term shifts in the general standard of living. It is hypothesized that the response would have been stronger the lower the standard of living. The relationship between age-specific mortality levels and real-wage series for Sweden 1751–1860 is analyz

The event-by-event correlations between three flow amplitudes are measured for the first time in Pb-Pb collisions, using higher-order symmetric cumulants. We find that different three-harmonic correlations develop during the collective evolution of the medium when compared to correlations that exist in the initial state. These new results cannot be interpreted in terms of previous lower-order flow

Raytracing is a widespread tool for room acoustic simulations, and one of its main advan-tages is the inclusion of surface scattering. Although surface scattering has been acknowledged as a central aspect of accurate raytracing simulations for many years, there is ongoing research into its effects and how to implement it better. This study evaluates three different algorithms for surface scatterin

To control the evolution of a pandemic such as COVID-19, knowing the conditions under which the pathogen is being transmitted represents a critical issue, especially when implementing protection strategies such as social distancing and wearing face masks. For viruses and bacteria that spread via airborne and/or droplet pathways, this requires understanding how saliva droplets evolve over time afte

This dissertation is about visual perception of material properties and their role in preparation for object handling. Usually before an object is touched or picked-up we estimate its size and shape based on visual features to plan the grip size of our hand. After we have touched the object, the grip size is adjusted according to the provided haptic feedback and the object is handled safely. Simil

Various procedures to improve the sensitivity and precision of antigen quantitation by immunocapillarymigration are investigated. The best results are obtained when using porous strips of cellulose acetate with covalently attached antibodies and when enzyme-labeled antibodies are used to expose the antigen-covered areas of the strips. Such a system has a sensitivity of 0.15 mg/liter and a precisio

Capsule A combination of several biometric measures enables the reliable sexing of the European Bee-eater Merops apiaster, a species with subtle sex differences in plumage and morphometry. Aims To explore variation in biometrics and their suitability to discriminate sex in adult European Bee-eaters Merops apiaster. Methods We sampled populations of a long-distance migratory species with low sexual

The ALICE Collaboration reports the first fully-corrected measurements of the N-subjettiness observable for track-based jets in heavy-ion collisions. This study is performed using data recorded in pp and Pb-Pb collisions at centre-of-mass energies of s = 7 TeV and sNN = 2.76 TeV, respectively. In particular the ratio of 2-subjettiness to 1-subjettiness, τ2/τ1, which is sensitive to the rate of two

Since the Rose Revolution (2003), Georgia has encountered an unprecedented scale of institutional reforms concomitant with the rise of American and European involvement in the “democratization” process. Various scholars have suggested that Georgian nationalism developed from an ethno-cultural basis to a more civic/liberal orientation after the Rose Revolution. This paper analyzes Georgian national
