A lyotropic nonionic lamellar system composed of pentaethyleneglycol mono n-dodecyl ether and D(2)O was studied using natural abundance (13)C NMR under magic-angle spinning. Applying a two-dimensional recoupling method proposed by Dvinskikh (R-PDLF), (1)H-(13)C dipolar couplings were estimated over a range of temperatures (300-335 K), thus enabling analysis of structural changes in the liquid crys

In the industry simulation models are commonly used in system development. These models can become complicated in order to capture the physical behaviour of the underlying dynamical system. A high-fidelity representation, which can result in long simulation times, is in some settings not strictly required. A method for overall model fidelity reduction is therefore of interest. In this thesis, two

We have attached quaternary ammonium (QA) groups to poly(phenylene oxide) via flexible and stable heptyl side chains by using a straightforward synthetic route involving bromoalkylation and quaternization. Membranes based on these polymers showed efficient phase separation, significantly enhanced hydroxide ion conductivity and far superior alkaline stability in relation to corresponding polymers w

Objective. The purpose of the present analysis was to analyze and compare the cost-effectiveness of solifenacin flexible dosing (5-10 mg) with tolterodine 4 mg sustained release (SR) or placebo (assumed to be comparable to no treatment) for patients with overactive bladder (OAB) symptoms. Design. A decision-analytic model was constructed. Methods. Costs and effects were evaluated for the three tre

OBJECTIVE: To investigate the possible role of FCGR2A 519A>G and FCGR3A 559A>C functional polymorphisms in the genetic predisposition to susceptibility to systemic sclerosis (SSc) or clinical phenotype. METHODS: A total of 1566 patients with SSc and 2271 geographically matched controls were included in our study. We analyzed the genotype and allele frequencies of the FCGR2A 519A>G and FCGR3A 559A>

Popular Abstract in English In the past ten years, homogeneous charge compression ignition (HCCI) combustion has been one of the subjects receiving great research interests in the combustion research community and the engine industry. This is because HCCI combustion processes have the potential of not only capable providing high efficiency like diesel engine combustion, but also producing much lowLarge Eddy Simulation (LES) modeling is developed to study homogeneous charge compression ignition (HCCI) combustion under different engine operation and mixture conditions, including real engine configurations and generic test cases. A previously developed HCCI model has been validated by comparing the simulation results with engine experiments. A new spark-assisted HCCI (SACI) combustion model h

In this study we have obtained 17 cosmogenic exposure ages from three well-developed moraine systems - Halland Coastal Moraines (HCM), Goteborg Moraine (GM) and Levene Moraine (LM) - which were formed during the last deglaciation in southwest Sweden by the Scandinavian Ice Sheet (SIS). The inferred ages of the inner HCM, GM and LM are 16.7 +/- 1.6, 16.1 +/- 1.4 and 13.6 +/- 1.4 ka, respectively, w

Background: Patients in palliative care are often treated with antithrombotics, even in the late stages of disease. Clear guidelines regarding deprescribing are lacking. Objective: The aims of this study were to investigate bleeding as a side effect of antithrombotic treatments the last year in life and map the timing of deprescribing. Methods: A retrospective cohort study was performed. All medic

As the world is becoming more digital, the use of data is rapidly increasing. To protect all EU citizens from privacy and data breaches, the regulations will become stricter. The General Data Protection Regulation (GDPR) will become effective on the 25th of May 2018. This will mean big structural changes for organizations, but it will also mean tougher requirements for gathering and maintaining pe

Direct conversion receivers are widely used for full duplex mobile radio communication systems. This paper describes a novel SAW-less single-ended RF amplifier connected to a single-ended mixer with a feedback loop that suppresses the second-order distortion from TX cross modulation of the LO-leakage as well as DC-offset at the mixer output. In Monte Carlo simulations the design achieves +47 dBm m

In this thesis the question concerning possible influence of language on thinking was addressed by investigating constituent orders in non-verbal representations of motion events. Forty-nine participants, 25 native speakers of Swedish with the default order SVO (or Agent-Act-Patient), and Kurdish with SOV (Agent-Patient-Act) were recruited in Sweden and 24 in Iraqi Kurdistan to take part in an exp

Understanding the role of intrinsic magnetic order on the oxygen evolution reaction (OER) requires careful consideration of the magnetic properties of both the catalytic surface and bulk under operating conditions. Because these often diverge from those of the pristine material, operando characterization that directly links magnetic behavior to catalytic activity is essential. Here, we investigate

The XUV beams generated via high order harmonic generation (HHG) in gases have spatial properties evolving with the harmonic order. It leads to chromatic aberrations when the harmonics are focussed so that, locally, the spectral content can change significantly during propagation [1-3] especially near focus.
