Utvärdering av mätningar på en solvärmeanläggning för en industribyggnad. Solvärmeanläggningen används för förvärmning av tappvarmvatten och för värmning av ventilationsluft till en stor maskin- och lagerhall.
Syftet med denna skrift är att exemplifiera hur man kan välja klimatdata för olika beräkningar som bör genomföras vid en fuktdimensionering. Klimatparametrarna finns sammanställda i ett PC-program som heter KLIMATDATA. Programmet är fritt tillgängligt att hämta hem. Värdena på de olika klimatparametrarna är sammanställda från tio olika meteorologiska mätstationer i Sverige för 30-årsperioden 1961-
Global error bounds are derived for full Galerkin/Runge-Kutta discretizations of nonlinear parabolic problems, including the evolution governed by the p-Laplacian with p >= 2. The analysis presented here is not based on linearization procedures, but on the fully nonlinear framework of logarithmic Lipschitz constants and an extended B-convergence theory. The global error is bounded in L-2 by Delta
Quality of life has various dimensions with multiple meanings for people. One vital issue is whether a person's subjective experienced quality of life correlates with his or her personality. Several studies show a correlation between personality and quality of life, life satisfaction or well-being. The aim of this study was to examine the relationship between personality and life quality, in parti
The investigated EO27-PO39-EO27 triblock copolymer, Pluronics P-85, is a nonionic surface-active agent which has a monomeric molecular weight of 4600, of which 500% corresponds to the PEO component. P-85 exist in complex states of aggregation in aqueous solution. Monomers, micelles and larger aggregates (clusters) coexist at lower concentrations in relative proportions which depend on temperature.
The fungicide prochloraz has got multiple mechanisms of action that may influence the demasculinizing and reproductive toxic effects of the compound. In the present study, Wistar rats were dosed perinatally with prochloraz (50 and 150 mg/kg/day) from gestational day (GD) 7 to postnatal day (PND) 16. Caesarian sections were performed on selected dams at GD 21, while others were allowed to give birt
The aim of this retrospective study was to analyze survival and prognostic factors in 111 consecutive patients undergoing curative resection of liver metastases from colorectal cancer. In addition, the time periods 1971-1984 and 1985-1995 were compared; criteria for first liver resection did not change with time, whereas the attitude toward re-resection was more aggressive during the latter period
A hollow fiber supported liquid membrane extraction method for the liquid chromatographic determination of dinitrophenolic compounds at ppt levels has been developed. Different variables affecting the extraction process, such as extraction time, shaking speed, acceptor pH, acceptor buffer concentration, salt content and humic acids have been studied. Enrichment factors up to 7000 times were obtain
A nonlinear 3D finite element model and a theoretical parameter study in relation to glued-in rods for timber structures are presented. A strain-softening crack band model was used to characterise the behaviour of the adhesive layer between the rod and the wood. The model is general in the sense that it bridges the gap between the theory of an ideal plastic bondline and the theory of linear elasti
Seventy standardized ringing sessions were carried out from April 1997 to August 2000 in a reedbed in Ria de Aveiro at Salreu, Portugal. The variation in the abundance of the common species is described as well as some aspects of their weight dynamics. Both, number of birds and species were higher during summer and autumn, when passage migrants occur and the number of juveniles is high. The pre-br
The author (professor of Scandinavian linguistics, *1934, living in Lund or nearby) compares his own dialect with that of his mother (house-wife, *1912, living nearly all her life 15 kilometers outside Kalmar). Interestingly, he found very few differences. The article discusses why.
En ny modell som beskriver samspelet mellan de olika materialen i ett golv lades fram på Chalmers i december 1998. I artikeln sammanfattas de olika delarna i modellen.
