We extend the classical notion of an outer action alpha of a group G on a unital ring A to the case when alpha is a partial action on ideals, all of which have local units. We show that if alpha is an outer partial action of an abelian group G, then its associated partial skew group ring A(star alpha) G is simple if and only if A is G-simple. This result is applied to partial skew group rings asso
Background: Approximately 20% of patients with bipolar disorder experience mixed states. Mixed states are associated with more comorbidity, poorer treatment response and prognosis, increased relapse rate, and decreased functioning. This study aimed to produce in-depth knowledge about bipolar patients' quality of life (QoL) and functioning related to mixed states. Sampling and Methods: This study u
Chondrules are millimeter-sized spherules that dominate primitive meteorites (chondrites) originating from the asteroid belt. The incorporation of chondrules into asteroidal bodies must be an important step in planet formation, but the mechanism is not understood. We show that the main growth of asteroids can result from gas drag-assisted accretion of chondrules. The largest planetesimals of a pop
Popular Abstract in Swedish Övergripande syfte Syftet med avhandlingen var att utvärdera hur en förenklad metod för diagnostisering av blodproppar i benets djupa ådror (djup ventrombos (DVT)) fungerar i svensk rutinsjukvård. Den förenklade metoden innebär användning av en strukturerad klinisk sannolikhetsbedömning tillsammans med ett blodprov (D-dimer test). Vi jämförde också vår D-dimermetod med The combination of pre-test clinical probability assessment and D-dimer test is now widely applied in the diagnostic process of DVT. The general objective of the present investigation was to validate these results in a Swedish routine emergency setting were the prevalence of the disease is high and were the clinical probability assessment was handled by many junior physicians. Furthermore, our aim
An unparalleled resolution is reported with an inelastic X-ray scattering instrument at the Cu K-edge. Based on a segmented concave analyzer, featuring single-crystal quartz (SiO2) pixels, the spectrometer delivers a resolution near 25 meV (FWHM) at 8981 eV. Besides the quartz analyzer, the performance of the spectrometer relies on a four-bounce Si(553) high-resolution monochromator and focusing K
The ability to anticipate future events and to modify erroneous anticipatory actions is crucial for the survival of any organism. Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires “expectations” or “internal models”. However, except in a metaphorical sense, the cerebellum, which consists of a set of interco
Evidence-based medicine (EBM) uses the current best evidence to inform decisions about care of individual patients, healthcare procedures, and technologies. The "gold standard" for optimal evidence in the Cochrane system is Level I randomized, controlled trials (RCTs) and meta-analyses of several RCTs. In order to achieve this level of evidence, one of the most important measures is the use of out

: Molecular imprints are potentially fantastic constructions. They are selective, robust, and nonbiodegradable if produced from stable polymers. A range of different applications has been presented, everything from separation of enantiomers, via adsorbents for sample preparation before analysis to applications in wastewater treatment. This chapter deals with molecularly imprinted polymers (MIPs) a
Position isomerism is ubiquitous in atmospheric oxidation reactions. Therefore, we have compared surface-active oxygenated amphiphilic isomers (1- and 3-pentanol) at the aqueous surface with surface- and chemically sensitive X-ray photoelectron spectroscopy (XPS), which reveals information about the surface structure on a molecular level. The experimental data are complemented with molecular dynam
This review covers recent developments on the topic of DNA gel particles formed in water-water emulsion-type interfaces. A general understanding of interactions between DNA and oppositely charged agents has given us a basis for developing novel DNA-based materials, including gel particles. The association strength, which is tuned by varying the chemical structure of the cationic cosolute, determin
This guideline for the investigation and initial treatment of atypical hemolytic uremic syndrome (HUS) is intended to offer an approach based on opinion, as evidence is lacking. It builds on the current ability to identify the etiology of specific diagnostic sub-groups of HUS. HUS in children is mostly due to infection, enterohemorrhagic Escherichia coli (EHEC), Shigella dysenteriae type 1 in some
BACKGROUND: Animal studies indicate that some phthalate metabolites may harm female reproductive function. OBJECTIVES: We assessed the associations between exposure to phthalate metabolites and pregnancy loss. METHODS: Using a previously established cohort of couples planning their first pregnancy, we analyzed four primary and two oxidized secondary phthalate metabolites in urine samples collected
Carbon nanotubes (CNTs) were synthesized on liquid flame sprayed (LFS) powder substrate of iron oxide doped Al2O3-ZrO2. Iron oxide doped Al2O3-ZrO2 nanopowder was produced by injecting the liquid precursor of aluminium-isopropoxide, zirconium-n-propoxide, ferrocene and p-xylene into a high temperature (similar to 3000 K) flame. The precursor solution was atomized by high-velocity H-2 flow and inje
The aim was to explore patients' experiences of information and their information needs after discharge for colorectal cancer surgery.
Eliminating fast neutrons (lambda < 0.5 angstrom) by removing direct line of sight between the source and the target sample is a well established technique. This can be done with little loss of transmission for a straight neutron guide by horizontal curving. With an elliptic guide shape, however, curving the guide would result in a breakdown of the geometrical focusing mechanism inherent to the el
