Older Adults Show Preserved Equilibrium but Impaired Step Length Control in Motor-Equivalent Stabilization of Gait
Stable walking depends on the coordination of multiple biomechanical degrees of freedom to ensure the dynamic maintenance of whole-body equilibrium as well as continuous forward progression. We investigated adult age-related differences in whole-body coordination underlying stabilization of center of mass (CoM) position and step pattern during locomotion. Sixteen younger (20-30 years) and 16 healt
Pulsating flow and mass transfer in an asymmetric system of bifurcations
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
Advances in Bone Tissue Engineering
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

A strong comparison principle of plurisubharmonic functions with finite pluricomplex energy
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 ${\cal E}_p(\Omega)$
Understanding the Electronic Structure of 4d Metal Complexes: From Molecular Spinors to L-Edge Spectra of a di-Ru Catalyst
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

Premixed jet flame characteristics of syngas using OH planar laser induced fluorescence
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
Modelling Regional Surface Energy Exchange and Boundary Layer Development in Boreal Sweden - Comparison of Mesoscale Model (RAMS) Simulations with Aircraft and Tower Observations
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
Identification of high beta-glucan oat lines and localization and chemical characterization of their seed kernel beta-glucans
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
A setup for resonant inelastic soft x-ray scattering on liquids at free electron laser light sources
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
A retrospective analysis of the clinical impact of 939 chest radiographs using the medical records.
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
Hymnoden Härdelin
"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
Experimental Studies of Ursolic Acid and Alkaline Sphingomyelinase in Colon Cancer and Colitis
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
Measurement of distributions sensitive to the underlying event in inclusive Z-boson production in pp collisions at root s=7 TeV with the ATLAS detector
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
Observation of the muon inner bremsstrahlung at LEP1
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
Nitrogen Isotope Patterns in Alaskan Black Spruce Reflect Organic Nitrogen Sources and the Activity of Ectomycorrhizal Fungi
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
Gel, glass and nematic states of plate-like particle suspensions: charge anisotropy and size effects
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
Insulin-like growth factor 1 has multisystem effects on fetal and preterm infant development.
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
