The aim of the present study was to take a closer look into the evidence for a theory of prehistoric string manufacture, formulated by the British archaeologist Karen Hardy in the article Prehistoric string theory. How twisted fibers helped to shape the world (Hardy, 2008). A problem with the article, with the relevance and validity of the presented evidence as substance for the theory, was the mi
Recent trends of permafrost thawing in the subarctic are expected to cause increased release of dissolved organic carbon (DOC) to inland waters, which might have cascading effects on downstream aquatic ecosystems and release of CO2 to the atmosphere. This study therefore aimed at evaluating the applicability of an empirical band ratio algorithm for estimating chromophoric dissolved organic matter
As previous research on content-specificity of the neural correlates of recollection is inconclusive, event-related potentials were used to assess old/new effects for faces, objects and words. The data demonstrate temporal differences in ERP old/new effects as a function of item type, supporting the notion that material-dependent processes underlie recollection-related neural activity. The results
We test a new approach to calculate the mean velocity and velocity dispersion for a sample of nearby stars when their radial velocities are not available. The most commonly used method (here called the projection method, PM) was introduced in a paper by Dehnen & Binney (1998). That method is here compared, theoretically and numerically, with an application of the Maximum Likelihood (ML) method
Background: With todays’ requirement of shorter product life cycles and faster time-to-market, producing companies experience an increased demand for faster transports in the supply chain. This puts pressure on freight forwarders to offer their customers a timely and reliable transport service at a reasonable price. Another challenge for the freight forwarders in Sweden is to provide such services
Fourier transform infrared spectroscopy (FTIRS) can provide detailed information on organic and minerogenic constituents of sediment records. Based on a large number of sediment samples of varying age (0-340 000 yrs) and from very diverse lake settings in Antarctica, Argentina, Canada, Macedonia/Albania, Siberia, and Sweden, we have developed universally applicable calibration models for the quant
A search for highly ionising, penetrating particles with electric charges from vertical bar q vertical bar = 2e to 6e is performed using the ATLAS detector at the CERN Large Hadron Collider. Proton-proton collision data taken at root s = 7 TeV during the 2011 running period, corresponding to an integrated luminosity of 4.4 fb(-1), are analysed. No signal candidates are observed, and 95% confidence
The ability to reliably estimate CO2 fluxes from current in situ atmospheric CO2 measurements and future satellite CO2 measurements is dependent on transport model performance at synoptic and shorter timescales. The TransCom continuous experiment was designed to evaluate the performance of forward transport model simulations at hourly, daily, and synoptic timescales, and we focus on the latter two
Background: Transanal endorectal one-stage pull-through (TERPT) procedure in children with Hirschsprung’s disease (HD) is frequently used worldwide. In order to give the families realistic expectations and to plan the medical care for the years after TERPT, the long term outcome is of great importance. Aim: To collect information on the long term outcome reported after one stage TERPT procedure fo
Objectives To evaluate the real-life effect of an evidence-based Gold Standard Programme (GSP) for smoking cessation interventions in disadvantaged patients and to identify modifiable factors that consistently produce the highest abstinence rates. Design Observational prospective cohort study. Setting GSPs in pharmacies, hospitals and communities in Denmark, reporting to the national Smoking Cessa
We present a search for a light (mass < 2 GeV) boson predicted by Hidden Valley supersymmetric models that decays into a final state consisting of collimated muons or electrons, denoted "lepton-jets". The analysis uses 5 fb(-1) of root s = 7 TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider to search for the following signatures: single lepton-jets with a
Non-negative matrix factorization (NMF) condenses high-dimensional data into lower-dimensional models subject to the requirement that data can only be added, never subtracted. However, the NMF problem does not have a unique solution, creating a need for additional constraints (regularization constraints) to promote informative solutions. Regularized NMF problems are more complicated than conventio
Diabetes mellitus is one of the most common endocrine disorders in dogs and is commonly proposed to be of autoimmune origin. Although the clinical presentation of human type 1 diabetes (T1D) and canine diabetes are similar, the aetiologies may differ. The aim of this study was to investigate if autoimmune aetiology resembling human T1D is as prevalent in dogs as previously reported.
Background The ankle brachial index (ABI) is related to risk of cardiovascular events independent of the Framingham risk score (FRS). The aim of this study was to develop and evaluate a risk model for cardiovascular events incorporating the ABI and FRS. Design An analysis of participant data from 18 cohorts in which 24,375 men and 20,377 women free of coronary heart disease had ABI measured and w
Cannulation of the papilla vateri represents an enigmatic first step in endoscopic retrograde cholangiopancreaticography (ERCP). In light of falling numbers of (diagnostic) ERCP and novel techniques, e. g. short-wire system, we were interested in the approach novice and experienced endoscopist are taking; especially, what makes a papilla difficult to cannulate and how to approach this. We devised
A bench-scale unit for the development of an enzymatic process for the bioconversion of lignocellulosics to ethanol has been used to study the recycling of waste-water streams to minimize fresh-water requirements and reduce effluent streams. Willow, after impregnation with sulphur dioxide, was steam-pretreated, enzymatically hydrolysed, and the sugars produced were fermented using S. cerevisiae. T
Background-Considerable variability exists in the use of pharmacological thromboprophylaxis among acutely ill medical patients, partly because clinically relevant end points have not been fully assessed in this population. We undertook an international, multicenter, randomized, double-blind, placebo-controlled trial using clinically important outcomes to assess the efficacy and safety of daltepari
Experience curves are used to analyse the prospects for diffusion and adoption of renewable energy technologies, with special emphasis on wind turbines and photovoltaic (PV) modules. The analysis shows that the possibility of cost reductions of renewable energy technologies is greater than for conventional energy technologies. However, large investments are necessary to make wind turbines and PV m
The use of a label for locally produced products is seen as a good way of promoting these products in Söderslätt and, thereby, promoting regional development. The only common meaning of the concept ?local? is the reference to a geographical area, even though the size of the area differs. Local products are associated with characteristics such as environment, ethics, health, quality and support of
