The development of robotized welding is truly impressive and is today one of the major application areas for industrial robots. The first industrial robots were introduced in the early 1960s for material transfer and machine tending. Not long after that, robots were used for spot welding and in the early 1970s for arc welding as well. During the years, significant developments have taken place bot
Popular Abstract in Swedish Vid blodbrist till en del av hjärtmuskeln, t.ex. vid ett stopp i ett av hjärtats kranskärl, kommer delar av hjärtmuskeln att vara utsatt för risk att drabbas av infarkt. Hjärtinfarkt definieras som döda hjärtmuskelceller. Det är av stor vikt för en patient med kranskärlssjukdom att man kan skilja de delar av hjärtmuskeln som drabbats av infarkt ifrån de delar som inte dBoth presence and extent of myocardial infarction are important prognostic factors for mortality and quality of life in patients with ischemic heart disease. Thus, it is of great clinical importance to be able to diagnose and characterize myocardial infarction. One way to diagnose myocardial infarction is by using the 12-lead electrocardiogram(ECG). For estimation of infarct size and location from
Two sets of experimental data on flame length under flat ceilings from a burner in a lower corner of a room have been correlated by conventional dimensionless variables. The correlations are shown to have considerable similarity to those of temperature distributions under ceilings caused by a heat source below. Matching is effected by a choice of temperature rise of approximately 180ºC.
About 25% of C2-deficient homozygotes have increased susceptibility to severe bacterial infections. C2-deficient homozygotes had significantly lower serum levels of IgG2, IgG4, IgD, and Factor B, significantly higher levels of IgA and IgG3 and levels of IgG1 and IgM similar to controls. Type I ( 28 bp deletion in C2 exon 6 on the [HLA-B18, S042, DR2] haplotype or its fragments) and type II ( non-t
Transition isotope shifts of 3s-3p transitions in Ne II and Ne III are measured in Fourier transform spectra from a hollow-cathode source. Accurate absolute line-center positions of the Ne-20 isotope are derived for the purpose of tertiary wavelength standards in the region 2000-5000 angstrom. A robust statistical treatment is applied, yielding line-position uncertainties that are lower than for t
Background/Aims: Duodenal ulcers should be treated by eradication of Helicobacter pylori. This study compared the efficacy of a proton pump inhibitor together with one or two antibiotics in eradication therapy, Methodology: 177 patients who were H. pylori positive were randomized to receive 14 days of either: lansoprazole 30mg bd and amoxicillin 1g bd (LA), omeprazole 20mg bd and amoxicillin 1g bd
Abstract in UndeterminedThis report is a study of literature found in the field of energy use in single-family houses. It is to be regarded as a first phase, part of the project "Sustainable energy use in houses". The literature examined refers to, predominantly, Swedish conditions, including Swedish building technique and the Nordic climate. The objectives of the report are to present topics of i
Currently, most protocols evaluating the efficacy of gallstone lithotripsy require a visualized gallbladder on oral cholecystography (OCG). The primary purpose of the OCG is to establish that the cystic duct is patent. When the gallbladder is visualized on OCG, it can also be used to number and size gallstones accurately. Patients with non-visualization of the gallbladder on OCG are excluded from
Dynamic mode I fracture initiation in impact loaded single edge bend specimens with a quarter notch is investigated by numerical modelling and the results are compared with sets of experimental data from two different steel qualities. The finite element analysis include 2D (two-dimensional) plane strain, 2D plane stress and 3D models. No crack growth is included in the calculations. The impact vel
PURPOSE: To study patients treated with panretinal photocoagulation regarding contrast sensitivity and visual recovery time after exposure to glare. METHODS: To compare contrast sensitivity and visual recovery-time after exposure to glare in eyes (n=20) from 20 type 1 diabetic patients treated with panretinal photocoagulation for proliferative retinopathy with eyes (n= 19) from 19 un-treated type
The Suicide Assessment Scale (SUAS) was constructed to be sensitive to change of suicidality. It was recently found to be predictive of suicide in a group of suicide attempters. The aim of the present study was to evaluate the reliability and validity of a modified interview version of SUAS with defined scores and also a new self-rating version (SUAS-S). The subjects consisted of former inpatients
Iodixanol (IDX) is a water soluble opacifier widely used in radiographical examinations of blood vessels and neural tissue, and it has been suggested as a potential contrast media in acrylic bone cement. The effect of the iodixanol particle size on the polymerisation process of the bone cement, the molecular weight, and the quasi-static mechanical properties have been investigated in this article.
In occupational therapy and occupational science, it is important to clarify the perspective from which the analysis of occupation is addressed. The purpose of this paper is to present a tentative structure for describing occupation, allowing for analysis in a lifelong panorama as well as for the immediate experience a person acquires from performing a single occupation. The concept of occupationa
The International Stem Cell Initiative characterized 59 human embryonic stem cell lines from 17 laboratories worldwide. Despite diverse genotypes and different techniques used for derivation and maintenance, all lines exhibited similar expression patterns for several markers of human embryonic stem cells. They expressed the glycolipid antigens SSEA3 and SSEA4, the keratan sulfate antigens TRA-1-60
Background and Purpose— The present study investigated the relationships between inflammation-sensitive plasma proteins (ISPs) and systolic blood pressure (SBP), as well as the joint long-term effects of ISP and SBP on incidence of stroke. Methods— BP and 5 ISPs (fibrinogen, {alpha}1-antitrypsin, haptoglobin, ceruloplasmin, orosomucoid) were assessed in 6071 healthy men 28 to 61 years of age. All
