The exposure to Th-232 from TIG welding with thoriated electrodes has been determined at five different workshops. Welding with both alternating and direct current was investigated. The exposure levels of Th-232 were generally below 10 mBq m(-3) in the breathing zone of the welders. Two samples from AC welding showed significant higher exposure levels, probably due to maladjustment of the TIG weld
Background. The best mode of delivery in cases of intrauterine growth restriction (IUGR) with umbilical artery blood flow changes is not well elucidated. Objective. To evaluate outcome in IUGR with umbilical artery blood flow changes planned for vaginal delivery after a negative oxytocin challenge test (OCT). Methods. In 84 term singleton pregnancies with suspected IUGR and no unanimous indicati
Mutations in the gene encoding laminin (LM) alpha 2 chain cause congenital muscular dystrophy. Here, we show that extraocular muscle (EOM) is spared upon complete LM alpha 2 chain absence. The major LM chains in limb muscle basement membranes are alpha 2, beta 1, beta 2 and gamma 1 whereas alpha 2, alpha 4, beta 1, beta 2 and gamma 1 chains are expressed in EOM. Expression of LMoA chain mRNA is fu
Background: Previous studies of patients with type 2 diabetes showed that cinnamon lowers fasting serum glucose, triacylglycerol, and LDL- and total cholesterol concentrations. Objective: We aimed to study the effect of cinnamon on the rate of gastric emptying, the postprandial blood glucose response, and satiety in healthy subjects. Design: The gastric emptying rate (GER) was measured by using st
At the age of 33 and mother of seven children (the husband a shawowy figure), Mrs Grönvall started a small but soon renowed hand book bindery in the town of Malmö in Southern Sweden in 1893. Mostly self-taught herself, through the years she housed and trained several apprentices and journeyman of wich some opened binderies of their own. At the Arts and Crafts Exhibition in Malmö 1907 she was award
The Rio Artiguas basin in central Nicaragua shows a distinctive case of environmental deterioration due to anthropogenic activities. Heavy metals used in gold mining and other wastes are continuously released into the rivers, representing a threat to the water quality. This article aims to evaluate the groundwater intrinsic vulnerability in the Rio Artiguas basin and to provide information for sus
A general model for pressure drop calculations in siphons and riser tubes has been developed. The model takes into account different physical flow phenomena such as the inlet pressure drop and the pressure drop in the tube. For each phenomenon, we applied theory and established correlations to calculate the separate accelerational, frictional, gravitational, and centrifugal pressure drops. Model r
In this work, a method has been developed to easily determine the effective diffusion coefficient (D-e) of a solute in a permeable membrane using electronic speckle pattern interferometry. Fringes are introduced parallel to the direction of diffusion during the diffusion process and D-e can be calculated by simple measurements on the interference pattern. For a fast and convenient determination of
Most adenoviruses bind to the coxsackie- and adenovirus receptor (CAR). Surprisingly, CAR is not expressed apically on polarized cells and is thus not easily available to viruses. Consequently, alternative mechanisms for entry of coxsackievirus and adenovirus into cells have been suggested. We have found that tear fluid promotes adenovirus infection, and we have identified human lactoferrin (HLf)

Popular Abstract in Swedish I avhandlingen studeras olika resolvent uppskattningar i harmonisk analys. I det första arbetet visas en Wiener taubersats med hjälp av resolventtransformen. I det andra arbetet studeras kvantitativa förfiningar av Wieners lemma i kommutativa kvasi-Banachalgebror och även i Banachalgebror. Det tredje arbetet behandlar den klassiska Cesàro-operatorn och dess verkan påThis thesis contains three papers about three different estimates of resolvents in harmonic analysis. These papers are: Paper 1. ``A Wiener tauberian theorem for weighted convolution algebras of zonal functions on the automorphism group of the unit disc'' Paper 2. ``Uniform spectral radius and compact Gelfand transform'' Paper 3. ``Decomposable extension of the Cesáro operator on the weighted B
HAMLET (human α-lactalbumin made lethal to tumor cells) is a protein-lipid complex that induces apoptosis-like death in tumor cells, but leaves fully differentiated cells unaffected. This review summarizes the information on the in vivo effects of HAMLET in patients and tumor models, on the tumor cell biology, and on the molecular characteristics of the complex. HAMLET limits the progression of hu
