Rapporten är en probleminventering av beständighetsproblem i samband med putsade fasader. I rapporten redovisas ett 10-tal typiska exempel på de vanligaste problemen, utan att diskutera skadeorsaker eller orsaksfrågor. Inventeringen avslutas med ett översiktligt forskningsprogram med inriktning på sprickbildning i puts på isolering och missfärgning av mineraliska ytskikt.

The influence of continuous inhalation of 150 ppm trichloroethylene (TCE) on body, liver, spleen, and kidney weights in rats, mice, and mongolian gerbils was tested. An age dependent decrease in body weight gain was observed in female rats exposed to TCE. All 3 spcies showed liver enlargement caused by the exposure. The effect was much more pronounced in mice, in which the increase was 60–80%, th
Background Ligands of peroxisome proliferator-activated receptor alpha (PPAR-alpha) have been shown to reduce ischaemia/reperfusion injury. The mechanisms behind this effect are not well known. We hypothesized that activation of PPAR-alpha exerts cardioprotection via a mechanism related to nitric oxide (NO) and endothelin-1 (ET-1). Methods Five groups of anaesthetized open-chest Sprague-Dawley rat
Twenty patients with carcinoma of the pancreas identified with ultrasonography and/or CT and confirmed by histology, were examined with MR before and after administration of an oral super-paramagnetic contrast medium. Ten patients were examined after administration of the contrast medium through a duodenal tube. Ten patients drank the contrast medium mixed with a viscosity-increasing agent. Organ
Aims To examine the prognostic importance of weight-change in patients with coronary artery disease (CAD), especially following acute myocardial infarction (AMI). Methods and results In 4360 AMI patients (OPTIMAAL trial) without baseline oedema, we assessed 3-month weight-change, baseline body mass index (BMI), demographics, patient history, medication, physical examination, and biochemical analys
I denna rapport ges några bilder av ekonomen i Sveriges kommuner och landsting. Förhoppningen är att dessa bilder bl.a. kan ge ett bidrag till de egenskaper och roller som tilldelas sektorns ekonomer. Bilderna förmedlas av den volymmässigt största andelen av sektorns ekonomer, d.v.s. de ekonomer som kan sägas vara underordnade en ekonomichef eller förvaltningschef. En fjärdedel av de nästan 600 ek
Adaptive tracking of non-linear dynamic plants is currently an important area of research. The main difficulty being felt by the research community is the lack of a general modelling framework that can facilitate synthesis of a simplistic control law while being capable of providing accurate approximation of non-linear systems. In this study a novel technique based on the control-oriented U-model
PURPOSE: Helicobacter pylori is a human gastroduodenal pathogen associated with type-B gastritis and gastric cancer. Low gastric tissue antioxidant levels are believed to increase the risk of developing gastric cancer. We investigated whether dietary antioxidant levels protect against infection and type-B gastritis in H. pylori-infected guinea pigs. METHODS: Dunkin-Hartley guinea pigs infected for
This paper introduces a generalisation of the notion of singular value for Hilbert space operators to more general Banach spaces. It is shown that for a simple integral operator of Hardy type the singular values are the eigenvalues of a non-linear Sturm-Liouville equation and coincide with the approximation numbers of the operator. Finally, asymptotic formulas for the singular numbers are deduced.
Serum determinations of the glial protein S100B has been found to correlate with brain damage after cardiac surgery. Forty-eight hours and later after surgery, increased S100B levels correlates with the presence of brain infarction, and the extent of infracted brain tissue. S100B at this time-point has been shown to predict long-term outcome, higher S100B levels correlated with decreased survival.
Endometrial stromal sarcomas (ESS) are rare neoplasms with the capacity both to invade the myometrium locally and to give rise to extrauterine metastases. Cytogenetic abnormalities have been reported in 22 cases of ESS, mostly involving rearrangements of chromosomes 6, 7, and 17. The most characteristic translocation of this tumor type, t(7;17)(p15-p21;q12-q21), was recently shown to generate a JA
Industrial interventions that focus on increased productivity may impair the ergonomics, on a workstation or individual level. This paper presents a method that characterises work time consumption and physical work load of manual work, using video recordings synchronised with physiological measurements of, e.g. muscular activity, and postures. The underlying idea was that it is possible to amalgam
This article reconstructs a Hebrew version of the Gloria in Luke 1: 14 with its focus on the righteous remnant of Israel and then analyses the early versions in Greek, Latin, Syriac and Coptic. Finally it gives some later interpretations of the canticle in literature, art and music.
