In 2019, migrant seasonal workers from outside the EU constituted approximately twenty percent of the hired workforce within the agricultural sector in Sweden. However, the total share of migrant seasonal workers is assumed to be even greater. During 2020 this figure dropped significantly due to the travel restrictions associated with the COVID-19 pandemic. According to the Federations of Swedish

This master thesis describes the development process of a prototyping process. It was carried out in collaboration with Axis Communications. When creating plastic prototypes, development engineers usually have two options, 3D-printing or injection molding using a soft tool. 3D-printing allows for fast and relatively cheap creation of prototypes which contributes to a fast product development proce

Popular Abstract in Swedish Små, trådlösa och portabla apparater utgör idag en stor del av vår uppkopplade värld. Under det senaste decenniet har dock flera teknologiska framsteg lett mot en utveckling där allt från maskiner till kläder kommunicerar med varandra. Detta brukar kallas för "sakernas internet" och uppskattas involvera 50 miljarder enheter år 2020. Genom att förse dessa enheter med små

Photoinduced electron transfer processes in perylene-titanium dioxide dye-semiconductor systems are studied. In particular, the influence of saturated and unsaturated aliphatic spacer groups inserted between the chromophore and the semiconductor substrate is investigated. The study is based on a recently developed method that combines first-principles electronic structure calculations to character

Purpose - H2O, CO2 and CO are three main species in combustion systems which have high volume fractions. In addition, soot has strong absorption in the infrared band. Thus, H2O, CO2, CO and soot may take important roles in radiative heat transfer. To provide calculations with high accuracy, all of the participating media should be considered non-gray media. Thus, the purpose of this paper is to st

We perform hydrodynamic simulations of mass transfer in binaries that contain a white dwarf and a neutron star (WD-NS binaries), and measure the specific angular momentum of material lost from the binary in disc winds. By incorporating our results within a long-term evolution model, we measure the long-term stability of mass transfer in these binaries. We find that only binaries containing helium

Summary of key messages for policy makers • Systemic approach is critical Climate change and natural resource depletion continues to be driven not least by unsustainable levels and patterns of consumption. There is growing recognition that the shift required to achieve sustainable consumption and production is a momentous paradigm shift in Western culture. Due to the holistic nature of shifting c

BACKGROUND: The occurrence of osteoarthritis (OA), associated meniscal injuries, meniscectomy, and patient-related measures for patients treated nonoperatively after anterior cruciate ligament (ACL) injuries have not been well described in the literature in terms of natural history. HYPOTHESIS: Patients with ACL injury can achieve a low occurrence of tibiofemoral OA and good knee function when tre

We measured angular distributions of differential cross section, beam analyzing power, and recoil polarization for neutral pion electroproduction at Q(2)=1.0 (GeV/c)(2) in 10 bins of 1.17 <= W <= 1.35 GeV across the Delta resonance. A total of 16 independent response functions were extracted, of which 12 were observed for the first time. Comparisons with recent model calculations show that respons

BACKGROUND: Female gender is a risk factor for sustaining anterior cruciate ligament (ACL) injury. However, little is known about possible sex differences in patients with ACL injury/reconstruction. PURPOSE: To study sex differences in patient-reported outcomes before and at 1 and 2 years after ACL reconstruction and to present reference values. STUDY DESIGN: Cohort study; Level of evidence, 2. ME

Avian migrants may fly at a range of altitudes, but usually concentrate near strata where a combination of flight conditions is favourable. The aerial environment can have a large impact on the performance of the migrant and is usually highly dynamic, making it beneficial for a bird to regularly check the flight conditions at alternative altitudes. We recorded the migrations between northern Europ

Fucoxanthin-chlorophyll protein (FCP) is the key molecular complex performing the light-harvesting function in diatoms, which, being a major group of algae, are responsible for up to one quarter of the total primary production on Earth. These photosynthetic organisms contain an unusually large amount of the carotenoid fucoxanthin, which absorbs the light in the blue-green spectral region and trans
