Gravoturbulent Planetesimal Formation: The Positive Effect of long-lived Zonal Flows

Recent numerical simulations have shown long-lived axisymmetric sub- and super-Keplerian flows in protoplanetary disks. These zonal flows are found in local as well as global simulations of disks unstable to the magnetorotational instability. This paper covers our study of the strength and lifetime of zonal flows and the resulting long-lived gas over- and underdensities as functions of the azimuth

Från ämbetsman till ämbetsbärare : förändringar speglade i anmälningar mot präster under tre brytningstider

Popular Abstract in Swedish Avhandlingen tar upp frågor om prästernas arbetsmiljö och deras roll och identitet. I inledningskapitlet framhölls att flera faktorer är viktiga för en undersökning om prästernas arbetsmiljö och för utformningen av prästrollen och prästidentiteten. Det omgivande samhället, de organisatoriska ramarna och de förväntningar som ställs på prästerna är några sådana faktorer, In this dissertation the work environment and the roles and identities of the clergy in the Church of Sweden are investigated. It is said in the first chapter that there are several factors influencing the work environment and that these factors are important for the formation of the roles and identities of the clergy. The surrounding society, the organization, and the expectations directed at the

In-vivo dark-field and phase-contrast x-ray imaging.

Novel radiography approaches based on the wave nature of x-rays when propagating through matter have a great potential for improved future x-ray diagnostics in the clinics. Here, we present a significant milestone in this imaging method: in-vivo multi-contrast x-ray imaging of a mouse using a compact scanner. Of particular interest is the enhanced contrast in regions related to the respiratory sys

Subgel transition in diluted vesicular DODAB dispersions

We have characterized the lipid chain freezing in dilute aqueous vesicle dispersions of the cationic lipid dioctadecyldimethylammonium bromide (DODAB) using wide and small angle X-ray scattering, solid state NMR, DSC, turbidity and density measurements. The lipids freeze in two steps. Above 40 degrees C the chains are fluid and the lipids are in a so-called liquid-crystalline state. When cooling b

Epidemiological studies of risk factors for injuries in an adult population

Popular Abstract in Swedish Dödligheten i skador i Sverige har under de senaste årtiondena minskat, en minskning som idag dock har planat ut. Antalet dödade i transportolyckor och i arbetsplatsolyckor i Sverige har minskat under de senaste 40 åren vilket kan ses som ett resultat av ett effektivt säkerhetsarbete. När det gäller fallolyckor så har däremot andelen som dör av sina skador ökat markant Injuries are often associated with long-term suffering and lowered functioning, and personal injuries impose a huge burden on medical care and health services in addition to the costs associated with impaired functional ability. Each year in Sweden, falling accidents are experienced by a third of those aged 60 or over and half of those aged 80 or over, while injuries from traffic accidents still a

Search for supersymmetry in events with photons, bottom quarks, and missing transverse momentum in proton-proton collisions at a centre-of-mass energy of 7 TeV with the ATLAS detector

A search has been performed for the experimental signature of an isolated photon with high transverse momentum, at least one jet identified as originating from a bottom quark, and high missing transverse momentum. Such a final state may originate from supersymmetric models with gauge-mediated supersymmetry breaking in events in which one of a pair of higgsino-like neutralinos decays into a photon

Search for new particles decaying to ZZ using final states with leptons and jets with the ATLAS detector in root s=7 TeV proton-proton collisions

A search is presented for a narrow resonance decaying to a pair of Z bosons using data corresponding to 1.02 fb(-1) of integrated luminosity collected by the ATLAS experiment from pp collisions at root s= 7 TeV. Events containing either four charged leptons (llll) or two charged leptons and two jets (lljj) are analyzed and found to be consistent with the Standard Model background expectation. Lowe

Mediatorless sugar/oxygen enzymatic fuel cells based on gold nanoparticle-modified electrodes

We report on the fabrication and characterisation of a gold-nanoparticle (AuNP)-based mediatorless sugar/oxygen biofuel cell (BFC) operating in neutral sugar-containing buffers and human physiological fluids, such as blood and plasma. First, Corynascus thermophilus cellobiose dehydrogenase (CtCDH) and Myrotheciumverrucaria bilirubin oxidase (MvBOx), used as anodic and cathodic bioelements, respect

Disruption of the Eng18B ENGase Gene in the Fungal Biocontrol Agent Trichoderm atroviride Affetcs Growth Conidation and Antagonistic Ability

The recently identified phylogenetic subgroup B5 of fungal glycoside hydrolase family 18 genes encodes enzymes with mannosyl glycoprotein endo-N-acetyl-b-D-glucosaminidase (ENGase)-type activity. Intracellular ENGase activity is associated with the endoplasmic reticulum associated protein degradation pathway (ERAD) of misfolded glycoproteins, although the biological relevance in filamentous fungi

[(BINAP)Re(O)Cl-3] as an efficient catalyst for olefination of chiral alpha-substituted aliphatic aldehydes

A convenient one-pot preparation of [(BINAP) Re(O)Cl-3] (6) is described. This complex was demonstrated to be an efficient catalyst for the olefination of aldehydes by reaction with alpha-diazo esters, with essentially quantitative yields and up to 98:2 geometric selectivity. The potential for using enantiopure [(BINAP)Re(O)Cl-3] (6) to promote an asymmetric kinetic resolution of racemic alpha-ste

Monitoring liquid displacement of model and industrial fluids in pipes by in-line ultrasonic rheometry

Liquid displacement of model and industrial fluids in pipes was successfully investigated using the in-line rheometer concept based on the combination of Ultrasound Doppler Velocity Profiling (UVP) and the pressure difference (PD) technique. The velocity profile development, related mixing zone and real-time changes in rheology were monitored when one fluid was displaced by another with different

On the scope and assessment of pesticides in groundwater in Skåne, Sweden

Popular Abstract in Swedish Grundvatten, det vatten som förekommer i hålrum i underjorden, är en av våra allra viktigaste naturresurser. Grundvattnet utgör den absolut största andelen för oss tillgängligt färskvatten och används för att producera mat och som processvatten inom olika industrier. Ungefär hälften av jordens dricksvattenförsörjning baseras på grundvattenuttag och ekosystem världen övePesticides are known to occur in groundwater worldwide. However, long-term pollution concerns and cause-effect relationships for specific regions remain limited. This thesis explores the occurrence of pesticides in south-Swedish groundwater, with the aims of providing a better knowledge basis for assessment and management of present-day and future pollution risks.

High-sensitive cardiac Troponin T is superior to echocardiography in predicting 1-year mortality in patients with SIRS and shock in intensive care

Background: Left ventricular (LV) dysfunction is well documented in the critically ill. We assessed 1-year mortality in relation to cardiac biomarkers and LV function parameters by echocardiography in patients with shock. Methods: A prospective, observational, cohort study of 49 patients. B-natriuretic peptide (BNP), high-sensitive troponin T (hsTNT) and transthoracic echocardiography (TTE) were a

Entanglement in quantum integrable and chaotic systems with Markov dynamics

Entanglement evolution is studied in open systems represented by rings of qubits with the Ising interaction and variously oriented external field and with Markov environments. The effect of thermal or dephasing environment is manifested as exponential decrease of the entanglement superposed on its dynamics in the isolated system. (C) 2009 Elsevier B.V.

Purpose: To investigate the effects of visual and tactile intra-oral sensor-position feedback for target selection tasks with the tip of the tongue. Method: Target selection tasks were performed using an inductive tongue-computer interface (ITCI). Visual feedback was established by highlighting the area on a visual display corresponding to the activated intra-oral target. Tactile feedback was esta

Indication for pharmacological treatment is often lacking: a cross-sectional study on the quality of drug therapy among the elderly.

Although the elderly have a substantially higher drug use than younger patients, even after adjustment for multimorbidity, there is limited knowledge about the elderly's indication for treatment. It is essential for elderly patients to have a well-planned drug therapy. The first step towards a correct and safe drug therapy is to ensure that the patient's drugs have an indication, i.e. correct diag

Joint occurrence of Merkel cell carcinoma and non-Hodgkin lymphomas in four Nordic countries

The objective of this study was to assess the reciprocal association between non-Hodgkin lymphoma (NHL) and Merkel cell carcinoma (MCC) using the data of four Nordic Cancer Registries. Data for this study were drawn from the Danish, Finnish, Norwegian, and Swedish cancer registries. Standardized incidence ratios (SIRs) for MCC among NHL patients, and for NHL among MCC patients, were calculated. Th

Zooplankton Feeding on the Nuisance Flagellate Gonyostomum semen

The large bloom-forming flagellate Gonyostomum semen has been hypothesized to be inedible to naturally occurring zooplankton due to its large cell size and ejection of long slimy threads (trichocysts) induced by physical stimulation. In a grazing experiment using radiolabelled algae and zooplankton collected from lakes with recurring blooms of G. semen and lakes that rarely experience blooms, we f
