Fabless production, meaning manufacturing without owning fabrication facilities, has been suggested as a novelty by the semiconductor industry. However, Ikea, the global furniture company based in Sweden, has successfully been producing their furniture in a fabless fashion since 1955. This paper explores how Ikea manage and control its almost fabless production to reach the company’s targets for s

In T lymphocytes, lipid rafts are preferred sites for signal transduction initiation and amplification. Many cell membrane receptors, such as the TCR, coreceptors, and accessory molecules associate within these microdomains upon cell activation. However, it is still unclear in most cases whether these receptors interact with rafts through lipid-based amino acid modifications or whether raft insert

Generation of precisely patterned neural cells from human pluripotent stem cells (hPSCs) is instrumental in developing disease models and stem cell therapies. Here, we provide a detailed 16-d protocol for obtaining high-purity ventral midbrain (VM) dopamine (DA) progenitors for intracerebral transplantation into animal models and for in vitro maturation into neurons. We have successfully transplan

Theory on plasticity driving speciation, as applied to insect–plant interactions (the oscillation hypothesis), predicts more species in clades with higher diversity of host use, all else being equal. Previous support comes mainly from specialized herbivores such as butterflies, and plasticity theory suggests that there may be an upper host range limit where host diversity no longer promotes divers

In light of the speedy technological development in society, technical standards are becoming increasingly important. In the early days, the specific tasks delegated to standardization bodies under the New Approach did not attract much political interest. Today, however, politicians and different stakeholders realize that the tasks delegated to the standardization industry are highly important for

Previous studies on organic sediment contaminants focused mainly on a limited number of highly hydrophobic micropollutants accessible to gas chromatography using nonpolar, aprotic extraction solvents. The development of liquid chromatography–high-resolution mass spectrometry (LC–HRMS) permits the spectrum of analysis to be expanded to a wider range of more polar and ionic compounds present in sedi

Background: The Activity Rating Scale (ARS) for disorders of the knee evaluates the level of activity by the frequency of participation in 4 separate activities with high demands on knee function, with a score ranging from 0 (none) to 16 (pivoting activities 4 times/wk). Purpose: To translate and cross-culturally adapt the ARS into Swedish and to assess measurement properties of the Swedish versio

Objective: This study investigated potential associations between novel biomarkers for cardiovascular disease and other surrogate markers for health. Methods: Community sample of 170 (92 boys and 78 girls) children aged 8–11 years. Total fat mass (TBF) and abdominal fat (AFM) were measured by Dual-energy x-ray absorptiometry (DXA). Total body fat was also expressed as percentage of total body mass

Refugee rights are reserved for the few lucky enough to evade the sophisticated deterrence regime, while the vast majority of the world’s refugees are referred to a life in semi-permanent limbo.

Many time-series smoothing methods can be used for reducing noise and extracting plant phenological parameters from remotely-sensed data, but there is still no conclusive evidence in favor of one method over others. Here we use moderate-resolution imaging spectroradiometer (MODIS) derived normalized difference vegetation index (NDVI) to investigate five smoothing methods: Savitzky-Golay fitting (S

This paper discusses social science education in four Swedish upper secondary schools as conceptualized – by teachers and students – and as carried out in the classroom. More specifically, it addresses education on migration, public international law and human rights in a classroom where about a third of the students have immigrant background. Analysing data collected through classroom observation

The spectral induced polarization (SIP) method is a promising method for many near surface applications, including characterization of contaminated soil. In this study, SIP measurements, high-resolution X-ray tomography and image analysis are combined to investigate clean and tetrachloroethylene (PCE) contaminated sand. This is the first known combination of these methods and the aim of this paper

The precise characterization of femtosecond laser pulses is as challenging as their generation and a topic of intense research. Dispersion-scan (d-scan) [1] is a recently established technique where the spectrum of a nonlinear signal, e.g., second-harmonic generation (SHG), is measured as a function of dispersion applied to the pulse. The spectral phase of the pulse can then be retrieved from the

Recent developments in drilling technology have resulted in about five to ten times faster penetration rates compared to penetration rates of conventional diamond drilling. The increased penetration rates open up for affordable drilling of deep boreholes in regions with cold crust, such as in Scandinavia, allowing for geothermal energy generation in enhanced geothermal systems. We present two infr

Objectives: The progression and pathophysiology of neuropathy in impaired glucose tolerance (IGT) and type 2 diabetes (T2DM) is poorly understood, especially in relation to autophagy. This study was designed to assess whether the presence of autophagy-related structures was associated with sural nerve fiber pathology, and to investigate if endoneurial capillary pathology could predict the developm

The bone material from three archaeological occupation phases at Huseby Klev provides the best source of evidence currently available about the subsistence strategies of pioneer settlers in Northern Europe. The results from Huseby Klev indicate that the pioneer settlers initially relied heavily on marine mammals for their sustenance. This subsistence strategy changed during the second and third oc
