Broad threat to humanity from cumulative climate hazards intensified by greenhouse gas emissions

The ongoing emission of greenhouse gases (GHGs) is triggering changes in many climate hazards that can impact humanity. We found traceable evidence for 467 pathways by which human health, water, food, economy, infrastructure and security have been recently impacted by climate hazards such as warming, heatwaves, precipitation, drought, floods, fires, storms, sea-level rise and changes in natural la

Om akademiskt hantverk

En hemgjord ask av näver -- vad behöver man? Ett stycke ny samhällsvetenskaplig kunskap -- vad behöver man? Den här texten är ett föredrag om akademiskt hantverk och dess material, verktyg, åskådliggörande, ändamål och estetik.

Refining Holocene geochronologies using palaeomagnetic records

The aperiodic nature of geomagnetic field variations, both in intensity and direction, can aid in dating archaeological artefacts, volcanic rocks, and sediment records that carry a palaeomagnetic signal. The success of palaeomagnetic dating relies upon our knowledge of past field variations at specific locations. Regional archaeo- and palaeomagnetic reference curves and predictions from global geo

Study of Deiodinase Type 2 Polymorphisms in Graves' Disease and Ophthalmopathy in a Swedish Population

Background: Deiodinase type 2 (DIO2) is an enzyme that catalyzes the production of the active form of thyroid -hormone triiodothyronine (T3) from thyroxine (T4) and is important for maintaining intracellular T3 levels. Single nucleotide polymorphisms (SNPs) in DIO2 were associated with several diseases. The association of SNPs in DIO2 with Graves' disease (GD) was suggested in 2 Russian studies. O

Semi-Hyperbolic Maps Are Rare

We prove in this article that the set of semi-hyperbolic rational maps has Lebesgue measure zero in the space of rational maps on the Riemann sphere for a fixed degree d = 2. This extends the earlier result [3] to its full generality.

Getting a job when times are bad : recruitment practices in Sweden before, during and after the Great Recession

Research on recruitment shows that networks matter and are effective as search channels. The aim of this article is to analyse how recruitment practices varies over time, and specifically, how it has varied before, during, and after the Great Recession 2008–2009. The findings are that recruitment practices change both in the short term, in relation to labour supply, which we can call a cyclical ef

Physical activity may compensate for prolonged TV time regarding pulse rate—a cross-sectional study

Background. Regular exercise reduces pulse rate, but it is less clear how prolonged sitting time affects pulse rate. Our hypothesis was that high physical activity could compensate for prolonged sitting time regarding the pulse rate. Methods. Regression analysis was performed on cross-sectional data including 47,457 men and women based on two Swedish cohort studies, EpiHealth (18–45 years) and Lif

Clutter analysis in a time-domain millimeter-wave reflectometry setup

In this work, we study the clutter and multi-path propagation in a time-domain millimeter-wave reflectometry setup, used for material characterization or short-range imaging. The signal energy and fidelity factor of the different reflection components is analyzed in dependence of the distance from the target. Due to the change in pulse distortion in the multi-path components, the system impulse re

Long-term follow-up of morbidity and mortality after aortic valve replacement with a mechanical valve prosthesis

AIMS: The aim of this study was to determine the incidence of valve-related complications in patients with a mechanical aortic valve prosthesis and to identify risk factors for an adverse outcome.METHODS AND RESULTS: In the 424 patients, event-free survival rates 5 and 10 years after aortic valve replacement were 62% and 37%, respectively. The linearized incidence of thromboembolic events was 4.4%

Low-energy epicardial pacing in children : the benefit of autocapture

BACKGROUND: Permanent cardiac pacing in children results commonly in augmented energy consumption because of the high pacing rates and the ample stimulation safety margin applied in children. Cardiovascular anatomy and limited venous access sometimes preclude the otherwise preferred endocardial approach. In this multicenter patient series, we studied the feasibility, safety, and energy saving obta
