Heart rate variability (HRV) is a measurable property used to describe the naturally occurring time differences between heartbeats and has shown to help with identifying both physiological and psychological disorders. HRV signals of 97 individuals were analyzed using spectral analysis. The data was non-stationary but was analyzed using stationary estimation methods, in which the original data was

This paper explores discourses about European colonialism and particularly Sweden's colonial legacy in Swedish upper secondary school history textbooks. All three textbooks are currently in use and are based on the latest school curricula from 2011. The theoretical framework used to analyze the textbooks consists of post-colonial feminist theories combined with a post structuralist perspective

[FeFe]-hydrogenases are highly efficient H(2)-evolving metalloenzymes that include cyanides and carbonyls in the active site. The latter is an Fe(6)S(6) cluster (the so-called H-cluster) that can be subdivided into a binuclear portion carrying the CO and CN(-) groups and a tetranuclear subcluster. The fundamental role of cyanide ligands in increasing the basicity of the H-cluster has been highligh

For model-based quantitative reconstructions of past vegetation cover on the scale of landscapes, pollen productivity estimates (PPEs) are key input parameters. In this study, we employed a random sampling strategy to collect moss polsters at 20 sites in Changbai Mountain, northeastern China. A detailed vegetation survey within 1000-m radius around each sampling point was carried out and digitized

A measurement of elastic deeply virtual Compton scattering gamma*p --> gamma p using e(+) p and e(-) p collision data recorded with the HI detector at HERA is presented. The analysed data sample corresponds to an integrated luminosity of 306 pb(-1), almost equally shared between both beam charges. The cross section is measured as a function of the virtuality Q(2) of the exchanged photon and the ce

Many buildings, both new and old, suffer from moisture-related problems, with negative consequences on health, costs for rebuilding and lost confidence in the building industry. These problems could have been avoided if moisture issues had been focused on and dealt with throughout the building process. A method for including moisture safety in the building process has therefore been developed. The

Problem: Niche co-evolution deals simultaneously with the number and the character of species within a community. How can a community of predators and prey adaptively radiate to fill available niches? How many niches are there? And, can adaptive speciation at evolutionary branching points successfully fill the niches of the ESS? Model features: We use a predator–prey model with one fitness-genera

Background: Old age at diagnosis is associated with poor survival in colorectal cancer (CRC) for unknown reasons. Recent data show that colonoscopy is efficient in preventing left-sided cancers only. We examine the association of Tumor Node Metastasis (TNM) classes with diagnostic age and patient characteristics. Methods: The Swedish Family-Cancer Database has data on TNM classes on 6,105 CRC aden

This paper investigates explanations of variation in the development of capital asset volume between Swedish local governments, 1999–2008. As a pre-study, four cases were performed, generating 7 suggested explanatory factors. Hypotheses were generated by combining the suggested factors with a new political economy framework, containing two general assumptions. A national dataset of Swedish local g

Direct ozone (O-3) injection is a promising flue-gas treatment technology based on oxidation of NO and Hg into soluble species like NO2, NO3, N2O5, oxidized mercury, etc. These product gases are then effectively removed from the flue gases with the wet flue gas desulfurization system for SO2. The kinetics and mixing behaviors of the oxidation process are important phenomena in development of pract

In this paper the design and demonstration of a 7 nm(3) h(-1) integrated steam reforming based hydrogen production unit using a Fischer-Tropsch diesel is reported. The system design is discussed in detail, including the fuel processor itself as well as the hydrogen purification and results from stand-alone operation of the combined unit operations is reported. Further, the results of an integratio

We present a high-resolution and independently dated multiproxy lake sediment record from the paleolake at Les Echets in southeastern France that displays synchronous changes in independent limnic and terrestrial ecosystem proxies, in concert with millennial-scale climate oscillations during the last glacial period. Distinct lake-level fluctuations, low lake organic productivity, and open, treeles

Currently, the majority of spent batteries are not recycled but become part of the household waste in many countries, especially in China which is the largest producer and consumer of batteries. This is due to many reasons, including the lack of governmental policies to encourage and facilitate battery return and recycling. In that context this research was designed to investigate the attitudes an

Biomass derived gases produced via gasification, pyrolysis, and fermentation are carbon neutral alternative fuels that can be used in gas turbines, furnaces, and piston engines. To make use of these environmentally friendly but energy density low fuels the combustion characteristics of these fuels have to be fully understood. In this study the structure and laminar burning velocity of biomass deri

Where conservation resources are limited and conservation targets are diverse, robust yet flexible priority-setting frameworks are vital. Priority-setting is especially important for geographically widespread species with distinct populations subject to multiple threats that operate on different spatial and temporal scales. Marine turtles are widely distributed and exhibit intra-specific variation

Objective: The aim of this study was to analyse the occurrence of neonatal early onset group B streptococcal (EOGBS) disease relative to maternal body mass index (BMI). Method: A cohort of Swedish parturients with an early pregnancy BMI registered was investigated. Data were retrieved from population-based registers during 1997-2001, (n = 344 127, elective caesarean section excluded). Medical reco

The reduction of the (A root 5x root 5)R27 degrees surface oxide on Pd(100) and Pd75Ag25(100) surfaces by CO has been investigated by high-resolution X-ray photoelectron spectroscopy in combination with kinetic analysis using the Avrami-Erofeev theory. For both surfaces we observed faster reduction with increasing temperature. Kinetic analysis indicates that the reduction process is phase boundary

All notified MRSA cases in SkAyenne County have been followed since 2000. We have investigated the MRSA epidemiology over time, method of acquisition, whether some spa types are more prone to spread, and/or cause more infections, and the connection between spa type and country of acquisition/origin. All cases between 2000 and 2010 were included. Infection or colonization and the presence of PVL ge
