A new climate era in the sub-Arctic: Accelerating climate changes and multiple impacts
Climate warming in the Swedish sub-Arctic since 2000 has reached a level at which statistical analysis shows for the first time that current warming has exceeded that in the late 1930' s and early 1940' s, and has significantly crossed the 0 degrees C mean annual temperature threshold which causes many cryospheric and ecological impacts. The accelerating temperature increase trend has driven simil
Meta-analysis in more than 17,900 cases of ischemic stroke reveals a novel association at 12q24.12
Objectives: To perform a genome-wide association study (GWAS) using the Immunochip array in 3,420 cases of ischemic stroke and 6,821 controls, followed by a meta-analysis with data from more than 14,000 additional ischemic stroke cases. Methods: Using the Immunochip, we genotyped 3,420 ischemic stroke cases and 6,821 controls. After imputation we meta-analyzed the results with imputed GWAS data fr

Validation of Self-testing as a Method to Estimate the Prevalence of Nickel Allergy
The aim of this study was to investigate the validity of self-patch testing for nickel allergy, in order to determine a cost-effective method for surveillance of the prevalence of nickel allergy. Population-based study including patch testing is the most reliable method to study the prevalence of allergy, but it is expensive and has logistical problems. A total of 191 dermatology patients referred
Financialisation of the environment: A literature review
This paper provides a review of research into financialisation of the environment, focusing on the role of financialisation in the interface between social and natural dimensions of sustainability, the geographical penetration of finance into environmental sectors, and its increasing control over the production of nature and environmental governance through regulating flows of capital and conseque
Prophylaxis and treatment of HIV-1 infection in pregnancy: Swedish Recommendations 2010
Prophylaxis and treatment with antiretroviral drugs and the use of elective caesarean section have resulted in a very low mother-to-child transmission of human immunodeficiency virus (HIV) during recent years. The availability of new antiretroviral drugs, updated general treatment guidelines and increasing knowledge of the importance of drug resistance, have necessitated regular revisions of the "
Implementation of a Modelica compiler using JastAdd attribute grammars
We have implemented a compiler for key parts of Modelica, an object-oriented language supporting equation-based modeling and simulation of complex physical systems. The compiler is extensible, to support experiments with emerging tools for physical models. To achieve extensibility, the implementation is done declaratively in JastAdd, a metacompilation system supporting modern attribute grammar mec

Phase behaviour of colloids with short-range repulsions plus nonadsorbing polymer chains
The colloidal gas-liquid phase behaviour has been studied for aqueous mixtures of well-defined spherical particles with short-ranged repulsions mixed with relatively monodisperse poly(ethylene oxide) polymers. We show that our set of experimental phase diagrams are in quantitative agreement with theoretical predictions using generalized free volume theory [G. J. Fleer and R. Tuinier, Phys. Rev. E,
Study on administration of 1,5-anhydro-D-fructose in C57BL/6J mice challenged with high-fat diet
1,5-Anhydro-D-fructose (AF) is a mono-saccharide directly formed from starch and glycogen by the action of alpha-1,4-glucan lyase (EC 4.2.2.13). Our previous study has indicated that AF increases glucose tolerance and insulin secretion in NMRI mice after administration through a gastric gavage in a single dose at 150 mg per mouse. In this study, we used high-fat feeding of C57BL/6J mice to examine
Do quantum mechanical energies calculated for small models of protein-active sites converge?
A common approach for the computational modeling of enzyme reactions is to study a rather small model of the active site (20-200 atoms) with quantum mechanical (QM) methods, modeling the rest of the surroundings by a featureless continuum with a dielectric constant of approximately 4. In this paper, we discuss how the residues included in the QM model should be selected and how many residues need
A structured approach to neurologic prognostication in clinical cardiac arrest trials
Brain injury is the dominant cause of death for cardiac arrest patients who are admitted to an intensive care unit, and the majority of patients die after withdrawal of life sustaining therapy (WLST) based on a presumed poor neurologic outcome. Mild induced hypothermia was found to decrease the reliability of several methods for neurological prognostication. Algorithms for prediction of outcome, t

OSL in Household Salt (NaCl) for Environmental, Occupational and Medical Dosimetry
The recent progress in our work to implement salt (NaCl) as a dosemeter is presented. Laboratory investigations have indicated a linear dose response from 1 mGy to about 100 mGy and detection limits down to 0.1 mGy. Investigations in the clinic comparing TL-dosimetry in LiF and OSL in NaCl have indicated a similar dose response for the two dosemeters at different photon energies. Field studies wit
The male sex pheromone of the butterfly Bicyclus anynana: towards an evolutionary analysis.
BACKGROUND: Female sex pheromones attracting mating partners over long distances are a major determinant of reproductive isolation and speciation in Lepidoptera. Males can also produce sex pheromones but their study, particularly in butterflies, has received little attention. A detailed comparison of sex pheromones in male butterflies with those of female moths would reveal patterns of conservatio
Static Analysis and Transformation of Dataflow Multimedia Applications
An approach for merging statically schedulable subr egions in dataflow models is pr esented. The approach combines abstr act int erpr etation, loop analysis, and static scheduling of cyclo-static dataflow networ ks. The approach has been implemented in a Java-based tool that per forms automatic classification of dataflow act or s, generat ion of stat ic schedules using constr aint programming, and
Picosecond dynamics of laser-induced strain in graphite
We report on the use of grazing-incidence time-resolved x-ray diffraction to investigate the evolution of strain in natural graphite excited by femtosecond-laser pulses in the fluence range of 6-35 mJ/cm(2). Strains corresponding to up to similar to 2.8% c-axis expansion were observed. We show that the experimental data is in good agreement with calculations based on the Thomsen strain model in co
