Video vägleder vid anläggning av gastrostomiknapp hos barn. Tio års erfarenheter visar metodens fördelar
Tio års erfarenheter av att anlägga gastrostomier på barn med hjälp av videoendoskop redovisas. I patientgruppen ingår 300 barn i åldern 3 månader till 18 år med neurologiska åkommor, metabola sjukdomar, medfödda hjärtmissbildningar och maligna sjukdomar. Operationen görs i intubationsnarkos med en videoassisterad anläggning av gastrostomi där en s k gastrostomiknapp placeras direkt i stomat och a
The thermodynamic significance of the local volume averaged temperature
Since the temperature is not an additive function, the traditional thermodynamic point of view suggests that the volume integral of the temperature has no precise physical meaning. This observation conflicts with the customary analysis of non-isothermal catalytic reactors, heat pipes, driers, geothermal processes, etc., in which the volume averaged temperature plays a crucial role. In this paper w
The mitochondrial and prokaryotic proton-translocating NADH:ubiquinone oxidoreductases: similarities and dissimilarities of the quinone-junction sites
The catalytic properties of the rotenone-sensitive NADH:ubiquinone reductase (Complex I) in bovine heart submitochondrial particles and in inside-out vesicles derived from Paracoccus denitrificans and Rhodobacter capsulatus were compared. The prokaryotic enzymes catalyze the NADH oxidase and NADH:quinone reductase reactions with similar kinetic parameters as those for the mammalian Complex I, exce
Fluorescence lidar multispectral imaging for diagnosis of historical monuments - Övedskloster, a Swedish case study
A fluorescence lidar measurement has been performed on the castle Övedskloster in Sweden. A mobile system from the Lund University was placed at ~40 m distance from the sandstone façade. The lidar system, which uses a frequency-tripled Nd:YAG laser with a 355-nm pulsed beam, induces fluorescence in each target point. Areas were studied by using whisk-broom scans. The possibility of detecting biode
Macroporous molecularly imprinted polymer/cryogel composite systems for the removal of endocrine disrupting trace contaminants
A new concept for the preparation of selective sorbents with high flow path properties is presented by embedding molecularly imprinted polymers (MIPs) into various macroporous gels (MGs). A MIP was first synthetized with 17β-estradiol (E2) as template for the selective adsorption of this endocrine disrupter. The composite macroporous gel/MIP (MG/MIP) monoliths were then prepared at subzero tempera
Application of fuzzy partial least squares (FPLS) modeling nonlinear biological processes
We applied a nonlinear fuzzy partial least squares (FPLS) algorithm for modeling a biological wastewater treatment plant. FPLS embeds the Takagi-Sugeno-Kang (TSK) fuzzy model into the regression framework of the partial least squares (PLS) method, in which FPLS utilizes a TSK fuzzy model for nonlinear characteristics of the PLS inner regression. Using this approach, the interpretability of the TSK

Hormone-sensitive lipase is not required for cholesteryl ester hydrolysis in macrophages.
Storage of cholesteryl esters in the cytoplasm of macrophages is one of the earliest and most ubiquitous event observed in the development of arteriosclerosis. Macrophages have an enormous capacity to uptake and store cholesterol in the form of cytosolic cholesteryl ester droplets. These stores are mobilized by the action of a neutral cholesteryl ester hydrolase (NCEH), producing free cholesterol
Synthesis of a Model-based Tire Slip Controller
The Anti-lock Braking System (ABS) is an important component of a complex steering system for the modern car. In the latest generation of brake-by-wire systems, the performance requirements on the ABS have changed. The controllers have to be able to maintain a specified tire slip for each wheel during braking. This thesis proposes a design model and based on that a hybrid controller that regulates
Magnetic properties of GaMnAs single layers and GaInMnAs superlattices investigated at low temperature and high magnetic field
Magnetotransport properties of GaMnAs single layers and InGaMnAs/ InGaAs superlattice structures were investigated at temperatures from 4 K to 300 K and magnetic fields up to 23 T to study the influence of carriers confinement through different structures. Both single layers and superlattice structures show paramagnetic-to-ferromagnetic phase transition. In GaMnAs/InGaAs superlattice beside the Cu
Long-term outcome of chronic hepatitis C infection in a low-prevalence area
BACKGROUND: Although hepatitis C virus (HCV) infection is recognized as an important causative factor in the development of liver cirrhosis and hepatocellular cancer (HCC), the strength of this correlation has been difficult to confirm in low-prevalence areas. METHODS: Stored serum samples from 987 consecutive (1978-88) patients with chronic liver disease were tested with an enzyme-linked immunoso
MnAs overlayer on GaN(000(1)under-bar)-(1 x 1) its growth, morphology and electronic structure
MnAs layer has been grown by means of MBE on the GaN(000 (1) under bar)-(1 x 1) surface. Spontaneous formation of MnAs grains with a diameter of 30-60 nm (as observed by atomic force microscopy) occurred for the layer thickness bigger than 7 ML. Ferromagnetic properties of the layer with Curie temperature higher than 330 K were detected by SQUID measurements. Electronic structure of the system was

Kvinnor och karoliner inför konsistorierna 1720–1722. En pilotstudie
Uppsatsen behandlar de ofta invecklade äktenskapsmål där karoliner och deras hustrur stod inför de kyrkliga konsistorierna i Göteborg, Stockholm, Visby och Växjö efter det stora nordiska krigets slut. Utifrån Bachtins dialogteori analyseras förhandlingarna som en dialog med kyrkolagen. De regionala skillnaderna mellan Stockholm och Göteborgs stad samt Växjö, Visby och landsbygden i Göteborgs stift
Clearance of iohexol, chromium-51-ethylenediaminetetraacetic acid, and creatinine for determining the glomerular filtration rate in pigs with normal renal function: comparison of different clearance techniques
RATIONALE AND OBJECTIVES: We wanted to improve determination of the glomerular filtration rate (GFR) with plasma clearance techniques because the alternative-renal clearance techniques-may involve inaccurate urine sampling or risk of urinary tract infection when bladder catheterization becomes necessary. Therefore, we compared the renal and plasma clearances of iohexol and chromium-51-ethylenediam
Verification and implementation of dynamic wedge calculations in a treatment planning system based on a dose-to-energy-fluence formalism
The use of dynamic movements on linear accelerators during irradiation has found a revised interest lately due to the integration of computers to control the accelerator. In this paper, dynamic wedge fields that are produced by moving one of the collimator blocks during irradiation are studied. Since these wedge fields differ from those of mechanical wedges, certain requirements are to be met on t
Carbon fibre-based microbiosensors for in vivo measurements of acetylcholine and choline
This report describes technical improvements to the manufacture of a carbon fibre electrode for the stable and sensitive detection of H2O2 (detection limit at 0.5 mu M). This electrode was also modified through the co-immobilisation of acetylcholinesterase (AChE) and/or choline oxidase (ChOx) in a bovine serum albumin (BSA) membrane for the development of a sensor for in vivo measurements of acety
