Social considerations in the procurement of road and railroad projects in Sweden

Purpose - Social sustainability is of increasing importance in societal development, which will affect the implementation of construction projects. The social responsibilities for both construction clients and suppliers will be an increasingly relevant part of their business processes. The objective of this study is to evaluate how the procurement process functions today with respect to social con

Methodological considerations for identifying multiple plasma proteins associated with all-cause mortality in a population-based prospective cohort

Novel methods to characterize the plasma proteome has made it possible to examine a wide range of proteins in large longitudinal cohort studies, but the complexity of the human proteome makes it difficult to identify robust protein-disease associations. Nevertheless, identification of individuals at high risk of early mortality is a central issue in clinical decision making and novel biomarkers ma

Exploring barriers to implementing product-service systems for home furnishings

The home furnishings sector faces substantial sustainability challenges resulting from increasing consumption and premature disposal. Innovative business models that provide access rather than ownership hold promise for addressing these challenges, but past research has found that such models face many barriers to success. As the environmental benefits of these business models can only be realised

AI-based detection of lung lesions in [18F]FDG PET-CT from lung cancer patients

Background: [18F]-fluorodeoxyglucose (FDG) positron emission tomography with computed tomography (PET-CT) is a well-established modality in the work-up of patients with suspected or confirmed diagnosis of lung cancer. Recent research efforts have focused on extracting theragnostic and textural information from manually indicated lung lesions. Both semi-automatic and fully automatic use of artifici

Experimental study of flame spread over thermally-thin inclined fuel surface and controlling heat transfer mechanism under concurrent wind

The fuel inclination and wind velocity play a significant role on the forward flame spread behavior. It deserves further study since the heat transfer mechanism and flame spread characteristics coupled these two factors are not clear yet. In this paper, a thermally thin slab of PMMA that could be inclined from a horizontal (0°) to a vertical (90°) angle is used to investigate flame spread behavior

Enhanced forensic DNA recovery with appropriate swabs and optimized swabbing technique

Efficient sampling with swabs is crucial for optimal forensic DNA analysis. The DNA recovery is determined by the skill of the practitioner and the compatibility between the applied swab and the surface. Here we investigate the impact of swabbing technique and swab type on the DNA yield. Thirteen different swabs from four categories (cotton, flocked nylon, small foam and large foam) provided equal

Oxidation kinetics of methyl crotonate : A comprehensive modeling and experimental study

The current study explores the combustion behavior of methyl crotonate (CH3CH=CHC(=O)OCH3), which is a short ester representative of large unsaturated methyl esters. Starting with a detailed kinetic model for methyl butanoate (CH3CH2CH2C(=O)OCH3) oxidation, revisions are introduced to the C0-C4 chemistry based on the recent Aramco mechanism 3.0. The resulting mechanism is combined with a short mod

In situ scanning x-ray diffraction reveals strain variations in electrochemically grown nanowires

Templated electrochemical growth in nanoporous alumina can be used to fabricate nanowires with applications in magnetic storage devices, hydrogen sensors, and electrocatalysis. It is known that nanowires, grown in such templates, are strained. The strain in nanoscale materials can influence their performance in applications such as catalysts and electronic devices. However, it is not well establis

Long-term data shows increasing dominance of Bombus terrestris with climate warming

While many bumblebee species decline due to climate and land-use changes, others cope well with contemporary conditions. One example is Bombus terrestris, which is common in intensively managed agricultural landscapes. During the 20th century its subgenus, which includes the B. lucorum complex (B. lucorum, B. cryptarum and B. magnus) came to dominate Scandinavian bumblebee communities, but the spe

Statistical analysis of departure deviations from shunting yards : Case study from Swedish railways

Departure deviations from shunting yards impact the reliability of rail freight services and the punctuality of a railway network. Therefore, the statistical analysis of these deviations are necessary for improving the operation of trains in mixed-traffic networks. In our paper, we conduct a detailed statistical analysis of departure deviations considering individual shunting yards characteristics

Cadmium, total mercury, and lead in blood and associations with diet, sociodemographic factors, and smoking in Swedish adolescents

Background: Despite their vulnerability to the toxic effects of certain metals, biomonitoring data on adolescents are limited. In the present study, we assessed blood concentrations of toxic metals (cadmium [Cd], total mercury [Hg], and lead [Pb] in a national representative sample of Swedish adolescents. We also examined the associations of Cd, total Hg and Pb with habitual intakes of major energ

Method development for multimodal data corpus analysis of expressive instrumental music performance

Musical performance is a multimodal experience, for performers and listeners alike. This paper reports on a pilot study which constitutes the first step toward a comprehensive approach to the experience of music as performed. We aim at bridging the gap between qualitative and quantitative approaches, by combining methods for data collection. The purpose is to build a data corpus containing multimo

Vilken svensk författare motsvarar Knut Hamsun och Örnulf Tigerstedt? : Reflektioner om nazistiska diktare i Norden

”Vilken svensk författare motsvarar Japans Yukio Mishima, Tysklands Ernst Jünger och Frankrikes Louis Ferdinand Céline?”, frågar en svensk debattör och forskare i en artikel 2016. Till dessa om än famösa så välkända namn adderar frågeställaren Norges Knut Hamsun respektive Finlands Örnulf Tigerstedt. Med denna fråga som utgångspunkt granskas och prövas i artikeln såväl nazistiska partiledare och n"Which Swedish author could be compared to Yukio Mishima of Japan, Ernst Jünger of Germany and Louis-Ferdinand Céline of France?”, a Swedish debater and researcher asks in an article in 2016. To these well-known, even if infamous, authors, Knut Hamsun of Norway and Örnulf Tigerstedt of Finland are added. With the question raised, Nazi party leaders and Nazi followers as well as national poets of S

Near ambient pressure photoelectron spectro-microscopy : From gas-solid interface to operando devices

Near ambient pressure scanning photoelectron microscopy adds to the widely used photoemission spectroscopy and its chemically selective capability two key features: (1) the possibility to chemically analyse samples in a more realistic gas pressure condition and (2) the capability to investigate a system at the relevant spatial scale. To achieve these goals the approach developed at the ESCA Micros

Can moisture affect temperature dependences of microbial growth and respiration?

It is of great importance to understand how terrestrial ecosystems will respond to global changes. However, most experimental approaches have focused on single factors. In natural systems, moisture and temperature often change simultaneously, and they can interact and shape microbial responses. Even though soil moisture and temperature are very important factors controlling microbial activity, the
