Assessment of the fire behaviour of sandwich panels is continuously under discussion. The fire behaviour of these panels is a combination of material characteristics such as the core material and mechanical behaviour of the panels such as joints, dilations etc. The use of small or intermediate scale tests can be questioned for such types of products. Within the proposed European product standard
Comment rendre compte du développement de l’accord sujet-verbe chez des apprenants adultes L2? Nous voulons montrer le caractère extrèmement lent et graduel de l’accord sujet-verb en français parlé, un développement qui nous semble compatible avec la fréquence des formes/fonctions en question dans l’input.
An analytical procedure based on microwave-assisted extraction (MAE) and standard addition was applied for the determination of banned azo dyes in bovine, sheep, and goat leather. Standard addition at four different concentration levels was performed using azo dyes, dissolved either in methanol or water. All dyes were determined indirectly by measuring their corresponding harmful aromatic amines,
The inhibitory innervation of guinea-pig urethral smooth muscle was investigated histochemically and functionally. The distribution of immunoreactivities to haem oxygenases (HO), neuronal NO synthase (nNOS), and vasoactive intestinal polypeptide (VIP) was studied, and the functional effects of the corresponding putative transmitters, CO, NO, and VIP, were assessed. HO-2 immunoreactivity was found
This article aims to illuminate the complexities involved in efforts to influence China's energy future. It brings forth three observations. First: China's authoritarian appearance is deceptive. Second: learning about concealed but pivotal actors and their motivations is not easy but important. Third: technology diffusion is obstructed by differences in expectations. Three summarising messages con
Aim: Respiratory syncytial virus (RSV) is a prominent cause of airway morbidity in children under 1 y of age. It is assumed that host factors influence the severity of disease presentation, and thus the need for hospitalization. The variation of IGHG genes from chromosome 14q32 are linked to serum IgG subclass levels but also to the variations in IgG responses to pneumococcal, meningococcal and Ha
A review of the book "Bibliotekarerne: En profession i et felt af viden, kommunikation och teknologi", discussing how the library profession has developed during the 20th century, with a focus on contemporary development; and in relation to technological change, changes in society and academia, as well as in how professions are analyzed.
This article outlines a laboratory study on sulphate resistance of self-compacting concrete (SCC). For this purpose, more than 40 cylinders of concrete were subjected to a solution with sodium sulphate, sea or distilled water during 900 days. Age at start of testing was either 28 or 90 days. Weight and internal fundamental frequency (IFF) were measured. Comparison was done with the corresponding p
Background. The aim of this study was to investigate differences in use of antenatal care in a multi-ethnic population in Malmo, Sweden, over a 4-year period. Age, parity, cohabiting status, use of an interpreter, and tobacco-use were examined to assess the potential effects of confounding factors. Methods. A 4-year (2000-2003) retrospective community-based register study was performed. Low-risk s
We have investigated the electron transfer from reduced tyrosine YD (YDred) and cytochrome b559 to the S2 and S3 states of the water oxidizing complex (WOC) in Photosystem II. The EPR signal of oxidized cyt b559, the S2 state multiline EPR signal and the EPR signal from YD@? were measured to follow the electron transfer to the S2 and S3 states at 245 and 275 K. The majority of the S2 centers was r
Denna rapport behandlar manuella metoder för injustering av passiva, sidokopplade flödesnät med hjälp av differenstryckmätning. För ett normalt värmesystem i en byggnad innebär detta i klartext injustering av stamventiler men inte av radiatorventiler.
Metoder för beräkning av årsvärmebehov med hänsyn till solvärmetillskott för en byggnad eller ett rum.
I denna avhandling behandlas mätning av ventilation, flöden, volymer, luftomsättning samt luftutbytestid och kolvströmningsgrad för olika flödesvägar och strömningssätt i småhus med spårgas. Teori och mät- och beräkningsmetoder utvecklas och tillämpas vid fältmätningar i småhus. Som mätobjekt används allergikeranpassade enplansvillor byggda av LB-hus i Talldalen som är frånluftsventilerade och zon
