Particle asymmetric-rotor descriptions of Ag105-109 negative parity states
The negative parity states of Ag105-109 are interpreted according to the generalized particle asymmetric-rotor model. In particular, the influence of the different Nilsson proton orbitals (lying near the Fermi level) on the theoretical level spectra and electromagnetic properties is investigated in detail. Furthermore, the analysis of the wave functions of the theoretical levels, and the contribut
Effect of a continuous trauma quality improvement programme on mortality in urban India: a non-randomised controlled trial
Background Trauma is the leading cause of quality-related mortality in low- and middle-income countries, with an estimated two million preventable deaths each year. Although trauma quality improvement programmes have been utilised in high-income countries for more than three decades, there is no high-level evidence of their effect on patient outcomes. We aimed to assess whether implementing a cont
Kronisk mesenteriell ischemi. Endovaskulär behandling lika effektiv som öppen kirurgi
Chronic mesenteric ischaemia is a rare but serious condition, which if untreated may cause death secondary to starvation or bowel infarction. As the symptoms are sometimes unspecific, its diagnosis may be delayed or missed. Although open surgical revascularisation has been the traditional treatment, a review of published reports suggests it to be associated with operative mortality rates of 6-9 pe
Characterization of the interphase in PPO/PMMA blends compatibilized by P(S-g-EO)
V2O3(0001) surface terminations: from oxygen- to vanadium-rich
Well-ordered epitaxial V2O3(0 0 0 1) films (thickness > 80 Angstrom) have been prepared on the clean Rh(1 1 1) surface and investigated with scanning tunnelling microscopy, low-energy electron diffraction, high-resolution electron energy loss spectroscopy and high-resolution X-ray photoelectron spectroscopy with synchrotron radiation. Atomically flat V2O3(0 0 0 1) surfaces, terminated by vanadyl (
Dose dependence of mass and microcalcification detection in digital mammography: free response human observer studies.
The purpose of this study was to evaluate the effect of dose reduction in digital mammography on the detection of two lesion types-malignant masses and clusters of microcalcifications. Two free-response observer studies were performed-one for each lesion type. Ninety screening images were retrospectively selected; each image was originally acquired under automatic exposure conditions, correspondin
The ABO blood group gene: a locus of considerable genetic diversity
The blood group ABO gene shows considerable polymorphism in most of the 7 exons. Introns examined so far have also shown blood group-related polymorphisms, as has an upstream enhancer region. Several polymorphisms affect the specificity of the gene product (glycosyltransferase) and explain the occurrence of blood group A and B. Various lethal mutations result in blood group O. Other mutations are

FPGA Controlled Pneumatic Variable Valve Actuation
A control system for pneumatic variable valve actuation has been designed, implemented and tested in a single cylinder test engine with valve actuators provided by Cargine Engineering AB. The design goal for the valve control system was to achieve valve lifts between 2 and 12 mm over an engine speed interval of 300 to 2500 rpm. The control system was developed using LabView and implemented on the
Resonant tunneling permeable base transistor based pulsed oscillator
A technology was developed to embed nm-sized metallic features in close vicinity to semiconductor heterostructures, which allows a direct integration of resonant tunneling diodes (RTD) inside the channel of permeable base transistor. A AlGaAs/InGaAs based RTD was grown by molecular beam epitaxy (MBE), with peak current density either 70 or 120 kA/cm2. A fundamental oscillation frequency
MAPKK-dependent growth factor-induced upregulation of P2Y2 receptors in vascular smooth muscle cells
The ATP- and UTP-sensitive P2Y2 receptor which mediates both contractile and mitogenic effects has recently been shown to be upregulated in the synthetic phenotype of the vascular smooth muscle cell (VSMC). Using a competitive RT-PCR we demonstrate that the P2Y2 receptor mRNA is increased by fetal calf serum and other growth factors in a MAPKK-dependent way. This was confirmed at the functional le
Differences in UV-B sensitivity between PSII from grana lamellae and stroma lamellae
UV-B treatment of thylakoid membranes or fractions derived from them accelerates the first rise (Fo---Fi phase) of variable fluorescence and slows down the second (Fi---Fm) rise. This can be observed for all membrane fractions but to different extents. The grana fraction is affected more by the UV-B treatment than are the intact thylakoids and the stroma lamella fraction. An exogenous electron acc
Macrocell-Wide Behavior of the Orthogonality Factor in WCDMA Downlinks
The orthogonality factor (OF) quantifies the loss of orthogonality between the signals transmitted simultaneously on a wideband code division multiple access (WCDMA) downlink due to multipath dispersion. It is one of the fundamental parameters that determines the signal-to-interference-plus-noise ratio at the output of the Rake receiver and, consequently, it has a significant impact on downlink sy
Comparison of measured and calculated absorbed doses from tangential irradiation of the breast
Calculated absorbed dose distributions from tangential irradiation of the breast have been compared with TLD measurements in a anthropomorfic body-shaped phantom which has gone through all phases of the radiation treatment planning cycle, including mapping of electron densities with a CT scanner, simulation of beam set-up and several treatments with an accelerator. The absorbed doses, measured in
Detection of specific Helicobacter pylori DNA and antigens in stool samples in dyspeptic patients and healthy subjects
In this study stool samples from dyspeptic patients and healthy subjects were used for detection of specific Helicobacter pylori antigens and DNA by immunoenzymatic test (PPHpSA) and semi-nested PCR (ureA-PCR), respectively. The H. pylori status was estimated by invasive endoscopy-based rapid urease test and histology or noninvasive urea breath test (UBT), and by serology (ELISA, Western blot). Th
InAs nanowire metal-oxide-semiconductor capacitors
We present a capacitance-voltage study for arrays of vertical InAs nanowires. Metal-oxide-semiconductor (MOS) capacitors are obtained by insulating the nanowires with a conformal 10 nm HfO2 layer and using a top Cr/Au metallization as one of the capacitor's electrodes. The described fabrication and characterization technique enables a systematic investigation of the carrier density in the nanowire

Atomistic simulations of buckling properties of gold nanowires
The purpose of this work is to present results from an ongoing study on how the presence of surfaces influences the buckling properties of nanowires. This study is performed using molecular statics simulations where the interatomic interaction is modelled using an embedded atom potential (EAM) fitted to gold properties. The considered nanowires have rectangular cross sections with cross sectional
