We have developed a phenomenological effective quantum-field theoretical model describing the "hadron gas" of the lightest pseudoscalar mesons, scalar σ-meson and σ-vacuum, i.e. the expectation value of the σ-field, at finite temperatures. The corresponding thermodynamic approach was formulated in terms of the generating functional derived from the effective Lagrangian providing the basic thermody
Ectodermal patterning of the chick embryo begins in the uterus and continues during gastrulation, when cells with a neural fate become restricted to the neural plate around the primitive streak, and cells fated to become the epidermis to the periphery. The prospective epidermis at early stages is characterized by the expression of the homeobox gene DLX5, which remains an epidermal marker during ga
Transverse mass dependence of the Bose-Einstein correlation function radius parameters in experimental data on two-pion correlation in hadronic decays of Z0, is compared to the intrinsic properties of the string model, using as an example production of identical kaon pairs by the JETSET event generator.
Engineering of the yeast Saccharomyces cerevisiae towards efficient d-xylose assimilation has been a major focus over the last decades since d-xylose is the second most abundant sugar in nature, and its conversion into products could significantly improve process economy in biomass-based processes. Up to now, two different metabolic routes have been introduced via genetic engineering, consisting o
In many cases fragmentation of molecules upon inner-shell ionization is very unspecific with respect to the initially localized ionization site. Often this finding is interpreted in terms of an equilibration of internal energy into vibrational degrees of freedom after Auger decay. We investigate the X-ray photofragmentation of ethyl trifluoroacetate upon core electron ionization at environmentally
An experimental and theoretical study has been made of the 3s-3p and 3p-d transitions in Ni XIX. The method of beam-foil spectroscopy, using 30-64 MeV Ni ions from a tandem accelerator, has been combined with theoretical calculations using the multiconfiguration Dirac-Fock (MCDF) program.
OBJECTIVE To examine duration of breastfeeding and timing of complementary foods and risk of islet autoimmunity (IA). RESEARCH DESIGN AND METHODS The Environmental Determinants of Diabetes in the Young (TEDDY) study prospectively follows 8,676 childrenwith increased genetic risk of type 1 diabetes (T1D) in the U.S., Finland, Germany, and Sweden. This study included 7,563 children with at least 9 m
Mitochondrial metabolism is a major determinant of insulin secretion from pancreatic β-cells. Type 2 diabetes evolves when β-cells fail to release appropriate amounts of insulin in response to glucose. This results in hyperglycemia and metabolic dysregulation. Evidence has recently been mounting that mitochondrial dysfunction plays an important role in these processes. Monogenic dysfunction of mit
Using a comparative case study on the closure of the research and development facilities of a pharmaceutical company in two regions in Sweden, this paper investigates the emergence of regional economic resilience from an agency perspective. Findings include a networked region engendering agency from non-state actors whilst substantial state intervention is needed to facilitate agency from a less n
The phase behavior in the oleic acid/sodium oleate/normal saline (0.15 M NaCl aqueous solution) system has been determined. For this purpose visual inspection of samples between crossed polarizers, and Small Angle X-ray diffraction was used to identify the various phases and their unit cell dimensions. A rich phase behavior was observed for the ternary system, featuring reverse micellar, micellar
This chapter introduces the system for crisis management in Sweden. Over the last century, Sweden has gone from being a poor European backwater to being among the countries with the highest human development in the world. The droughts and harsh winters that killed thousands and drove numerous Swedes to emigrate in the past are mere distractions today and the contemporary system for crisis manageme
There is low utilisation of plastic waste in the Nordic region and only a fraction of plastic materials go back into production processes through reuse and recycling practices. This paper aims to increase knowledge concerning factors that inhibit demand for recycled plastics, and to identify critical barriers for plastic recycling across the regional plastics value chain. A literature review and t
Background: To describe the uptake and system-level effects of the introduction of biosimilars in a setting without forced switching. Research design and methods: We used data from the Swedish Rheumatology Quality register from start of marketing of infliximab (Remsima® and Inflectra®) and etanercept (Benepali®) biosimilars until 31 December 2016. We compared users of each originator-product and i
Purpose: The purpose of this paper is to investigate the dynamic process of brand meaning creation by multiple stakeholders during corporate rebranding in the digital environment. Design/methodology/approach: By applying a symbolic interactionist perspective, the case study analyses a failed corporate rebranding of Gap. A variety of narratives by managers, consumers, designers, and marketing profe
We present the first structural determination of the Pt2(P 2O5H2)44- anion in solution by analyzing the extended X-ray absorption fine structure (EXAFS) spectrum of the Pt LIII edge. The data could be fit with a simple model involving single and multiple scattering paths to near and far P-atoms, bridging O-atoms, and the other Pt-atom in the binuclear complex. A Pt-Pt distance of 2.876(28) Å and a
The study focuses on mapping spatiotemporal patterns and detecting the potential drivers of traffic congestion with multi-source data. First, based on real-time traffic data retrieved from an online map, the k-means clustering algorithm was applied to classify the spatiotemporal distribution of congested roads. Then, we applied a geographical detector (Geo-detector) to mine the potential factors f
