A method for evaluating chloride binding capacity of concrete was proposed based on the adsorption from solution and chloride binding isotherms of OPC pastes and mortars with water-cement ratio 0.4, 0.6 and 0.8. The experimental results show that the chloride binding capacity of concrete strongly depends on the content of CSH gel in the concrete, regardless of the water-cement radio and the additi

The upper limit of flammability of hydrogen in air, oxygen, oxygen-helium, oxygen-neon, oxygen-argon and oxygen-carbon dioxide mixtures was measured at room temperature and pressures between 0.97 and 29 atm in two cylindrical bombs with volumes of 1.5 and 5.2 liters. The limit in ternary mixtures was determined in 20%, 40%, 60% and 80% helium, 20% neon and argon and 10% carbon dioxide concentratio

Dissolution of igneous feldspar and the formation and occurrence of secondary feldspar in tholeiitic basalts from the Hengill volcanic centre, in SW Iceland was studied by microprobe analysis of cuttings from two ca. 2000 m deep geothermal wells. Well NG-7 in Nesjavellir represents a geothermal system in a rift zone where the intensity of young, insignificantly altered intrusions increases with de

In the ammoxidation of toluene over a V2O5 catalyst, the variation of initial rates with partial pressures of oxygen, toluene and ammonia was determined for formation of carbon oxides. Dependencies obtained were analyzed and expressed in terms of rate equations. It was found that CO and CO2 are initial products formed at different sites, none of which are involved in selective reactions. The mecha

Breast cancer survival differs 9 percentage points between the neighbouring countries of Denmark and Sweden. The authors' aim was to analyse whether this was caused by early detection in Sweden. The extent of disease and outcome was compared in two population-based breast cancer cohorts in 1983-1989. Breast cancer management was decentralized in Denmark without mammography screening whereas treatm

Two important features of the global economy in the last few decades have been the increasing degree of regional economic integration and the increasing volatility of real exchange rates. Due to the EU membership and the single European currency, issues related to regional economic integration and exchange rate changes hold prominence on the business and political agenda in Sweden. This dissertat

Concentrations of PCB congeners were determined in precipitation and the annual and seasonal depositional fluxes were calculated for 16 (mostly rural) stations around the Baltic Sea during 1990-1993. The concentrations of individual congeners in precipitation were found to be influenced by atmospheric concentrations of PCBs, ambient temperature, precipitation volume and physico-chemical properties

We have studied the influence of bulk inversion asymmetry (BIA) and the relativistic part of the low-symmetry interface Hamiltonian (IH) on intersubband optical transitions, induced by linearly polarized light, between strongly hybridized electron-hole states in asymmetrical InAs/GaSb broken-gap quantum wells grown along the [001] direction. The self-consistent calculations were performed using th

En fältstudie på åtta mastarbetare utfördes under februari i Svealand och Norrland. Mastarbetarnas aktiviteter observerades under en vanlig arbetsdag i masten och hudtemperaturen på sju ställen på kroppen, kroppstemperatur och hjärtfrekvens registrerades kontinuerligt. De fick också skatta sin temperaturupplevelse och ansträngningsgrad flera gånger under dagen. Lufttemperaturen varierade mellan -1Désirée Gavhed, Kalev Kuklane, Ingvar Holmér. Work on masts in cold conditions. Arbetslivsrapport 1999:22. Eight tower operators were studied in February during their ordinary duties in masts in four regions of Sweden. The activities of the workers were observed during a full working day and the skin temperature at seven spots, body temperature and heart rate were measured continuously. They also

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

A thorough kinetic investigation of the ammoxidation of toluene over a V2O5 catalyst was carried out. Pressures of reactants were varied and rates for formation of benzonitrile and benzaldehyde were determined. Kinetic expressions completely describing experimental data were derived. A mechanisms is proposed on basis of both rate equations and other types of information published in the literature

Allelopathy, the release of extracellular compounds that inhibit the growth of other microorganisms, may be one factor contributing to the formation and/or maintenance of cyanobacterial blooms. We investigated the allelopathic effects of three cyanobacterial species (Nodularia spumigena, Aphanizomenon flos-aquae and Anabaena lemmermannii) that frequently form mass-occurrences in the Baltic Sea. We

Purpose: To suggest a more precise tool when assessing the risk of contrast-medium-induced nephropathy (CIN), i.e. the ratio between contrast medium (CM) dose expressed in grams of iodine (g-I) and estimated glomerular filtration rate in ml/min (eGFR; based on equations using serum-creatinine (s-Cr), weight, height, age, and/or sex), here named I-dose/GFR ratio. Material and Methods: A Medline sea

A packed-bed bioreactor inoculated with a mixed culture obtained from a contaminated site was used to continuously treat a saturated solution of nonylphenol. The reactor was operated at feeding rates of 13–112 ml h−1 and temperatures of 5.5, 10, and 15°C. Optimal bioreactor performance was achieved at 10°C and at a feeding rate of 84 ml h−1 (with a removal rate of 43 mg l−1 day−1 of nonylphenol).

Ninety-eight patients, 56 suffering according to DSM-IV of unipolar depression and 42 of somatoform disorders, were compared on the Beck Depression Inventory (BDI) total scale, the subscale of Somatic complaints and the Cognitive-affective subscale. A factor analysis performed on the total group revealed five factors used to determine new subscales: Depressed mood, Somatic manifestations, Loss of
