Pulsating flow through bifurcations are of general interest. In the human body such flows are also very common; for example in blood vessels and the respiratory tract. The characteristics of the flow in arteries have been related to the process of atherogenesis, based on the observation that the initial manifestation of the process is observed at certain common locations, i.e., near bifurcations i
Popular Abstract in Swedish Skador på skelettet kan uppstå efter bl.a. olyckor, tumörkirurgi eller strålning. Ofta är sådana skador mycket handikappande då de påverkar kroppens funktion, stabilitet och utseende. Om benvävnad saknas eller måste bytas ut använder man sig idag av mikrokirurgiska metoder, där man flyttar kroppseget ben från ett ställe till ett annat. Tyvärr innebär detta att man skapaBone deficiencies, caused by malformations, trauma or adverse effects from medical treatments, are a clinical challenge and often associated with reduced physical function and quality of life. Autologeous bone grafts can be used to reconstruct skeletal defects, but the right size and quality of bone might not always be available and even so, donor-site morbidity might follow. A pre-fabricated or t
We prove a strong comparison theorem in the class ${\cal E}_p(\Omega)$ of certain plurisubharmonic functions with infinite total complex Monge-Amp\`ere masses. We also obtain a convergence theorem in ${\cal E}_p(\Omega)$
L-2,L-3-edge X-ray absorption spectroscopy (XAS) has demonstrated unique capabilities for the analysis of the electronic structure of di-Ru complexes such as the blue dimer cis,cis-[(Ru2O)-O-III(H2O)(2)(bpy)(4)](4+) water oxidation catalyst. Spectra of the blue dimer and the monomeric [Ru(NH3)(6)](3+) model complex show considerably different splitting of the Ru L-2,L-3 absorption edge, which refl
Lean premixed flame characteristics of several typical low calorific value (LCV) syngases (basis CO/H-2/CH4/CO2/N-2), including bituminous coal, wood residue, corn core, and wheat straw gasification syngas, were investigated using OH planar laser induced fluorescence (PLIF) technology. OH radical distributions within the turbulent flame were measured for different turbulence intensities. Flame str
Simulation of atmospheric and surface processes with an atmospheric model (RAMS) during a period of ten days in August 2001 over a boreal area in Sweden were compared to tower measurements and aircraft measurements of vertical profiles as well as surface fluxes from low altitude flights. The shape of the vertical profiles was simulated reasonably well by the model although there were significant b
Oat, (Avena sativa) is an excellent source of mixed linkage beta-glucans ((1 -> 3)(1 -> 4)-beta-D-glucan), a dietary fibre with cholesterol lowering properties. Using a mutagenized oat-population we screened 1700 different lines and identified ten lines that displayed beta-glucan levels above 6.7% and 10 below 3.6%. The extreme values were 1.8% and 7.5%. We chose six lines with an increased- and f
We present a flexible and compact experimental setup that combines an in vacuum liquid jet with an x-ray emission spectrometer to enable static and femtosecond time-resolved resonant inelastic soft x-ray scattering (RIXS) measurements from liquids at free electron laser (FEL) light sources. We demonstrate the feasibility of this type of experiments with the measurements performed at the Linac Cohe
Objective. Between one-third and half of all radiology examinations worldwide are probably chest studies. The aim of the current study was to retrospectively evaluate the clinical influence of chest radiography. Methods. In a tertiary referral hospital, 939 consecutive daytime chest radiography examinations were evaluated. The outcome was classified as normal, incidental, or pathologic. The referr
"Härdelin the Hymnist" Alf Härdelin (1927–2014) was a Swedish theologian and medievalist. In addition to a large academic output, he wrote eleven original hymns and translated 213 from Latin or German into Swedish. This article begins by showing how integrated this activity was with Härdelin’s theological work: both as an academic and as a hymnist he followed the Dominican adage, contemplata alii
Sphingomyelin (SM) is a sphingolipid present in all eukaryotic cell membranes. Hydrolysis of SM by sphingomyelinase (SMase) generates ceramide, which has effects on cell-cycle regulation and apoptosis. Alkaline sphingomyelinase (Alk-SMase) is the main SM-hydrolysing enzyme in the human intestine, and earlier studies have shown that it has anti-proliferative properties on colon cancer cells, and th
A measurement of charged-particle distributions sensitive to the properties of the underlying event is presented for an inclusive sample of events containing a Z-boson, decaying to an electron or muon pair. The measurement is based on data collected using the ATLAS detector at the LHC in proton-proton collisions at a centre-of-mass energy of 7 TeV with an integrated luminosity of 4.6fb(-1). Distri
Muon bremsstrahlung photons converted in front of the DELPHI main tracker (TPC) in dimuon events at LEP1 were studied in two photon kinematic ranges: 0.2< E-gamma <= 1 GeV and transverse momentum with respect to the parent muon p(T) < 40 MeV/c, and 1< E-gamma <= 10 GeV and pT < 80 MeV/c. A good agreement of the observed photon rate with predictions from QED for the muon inner bremsstrahlung was fo
Global patterns in soil, plant, and fungal stable isotopes of N (delta N-15) show promise as integrated metrics of N cycling, particularly the activity of ectomycorrhizal (ECM) fungi. At small spatial scales, however, it remains difficult to differentiate the underlying causes of plant delta N-15 variability and this limits the application of such measurements to better understand N cycling. We co
The influence of the charge anisotropy and platelet size on the formation of gel and glass states and nematic phases in suspensions of plate-like particles is investigated using Monte Carlo simulations in the canonical ensemble. The platelets are modeled as discs with charged sites distributed on a hexagonal lattice. The edge sites can carry a positive charge, while the remaining sites are negativ
Poor postnatal growth after preterm birth does not match the normal rapid growth in utero and is associated with preterm morbidities. Insulin-like growth factor 1 (IGF-1) axis is the major hormonal mediator of growth in utero and levels of IGF-1 are often very low after preterm birth. We reviewed the role of IGF-1 in fetal development and the corresponding preterm perinatal period to highlight the
In this study, a method was developed for determination of steroid hormones (17beta-estradiol, estrone, 17alpha-ethynylestradiol) in tap and sewage water samples from Sweden. Sample preparation and analysis were performed by a hollow-fibre microporous membrane liquid-liquid extraction (HF-MMLLE) set-up combined with gas chromatography-mass spectrometry (GC-MS). In this approach, only the organic l
Background: In children with hypoplasia or aplasia of the radius (radial longitudinal deficiency) manual activity limitations may be caused by several factors; a short and bowed forearm, radial deviation of the wrist, a non-functional or absent thumb, limited range of motion in the fingers and impaired grip strength. The present study investigates the relation between these variables and activity
