Invändig tilläggsisolering : köldbryggor, fukt, rörelser och beständighet : thermal bridges, moisture problems, movements and durability = Internal additional insulation

The report deals with the problems which may be caused by internal additional insulation of an existing building component. Problems treated in this report are heat losses through and surface condensation at thermal bridges, condensation in the building components, stresses due to temperature and moisture content variations and possibly frost damage in facade materials. After internal insulation

Working in underground offices

The present doctoral dissertation discusses Japanese office employees' psychological reactions to their underground work environment. Studies I and III were methodological in nature and aimed at developing and validating instruments to be used in the empirical studies. The first empirical analysis (Study II) examined office employees' perception of the importance of windows, the lighting condition

Mature-onset obesity in interleukin-1 receptor I knockout mice

Interleukin-1 (IL-1) is a major mediator of inflammation that exerts its biological activities through the IL-1 type I receptor (IL-1RI). The body weights of IL-1RI(-/-) mice of both sexes started to deviate from those of wild-type mice at 5-6 months of age and were 20% higher at 9 months of age. Visceral and subcutaneous fat mass, measured by dual-energy X-ray absorptiometry and magnetic resonanc

Perinatal characteristics and risk of rheumatoid arthritis

Rheumatoid arthritis is a disease of unknown aetiology. Twin studies indicate the importance of genetic as well as environmental factors. 1 In terms of environmental factors, few risk factors are well established, and, in practice, rheumatoid arthritis cannot be attributed to any specific exposure. 2 Descriptive studies imply a birth cohort effect in the incidence of rheumatoid arthritis. 3 4 We a

Radiographic findings after cricopharyngeal myotomy

Single film examinations (iodine and/or barium) were reviewed in 28 patients who had undergone surgery on the cricopharyngeal muscle due to Zenker diverticula (24 patients), cricopharyngeal muscle incoordination (3 patients) and pharyngoesophageal web (one patient). All patients had had a myotomy which included the cricopharyngeal muscle and up to 3 cm of the cervical esophagus. Lateral and anteri

Relationship between somatic cell count, individual leukocyte populations and milk components in bovine udder quarter milk

The somatic cell count (SCC) in bovine milk is an indicator of udder health and milk quality. Individual cell populations, i.e., macrophages, lymphocytes and polymorphonuclear neutrophils, were identified and their relationship to milk components such as acute-phase proteins (serum amyloid A (SAA) and alpha(1)-acid glycoprotein), lactic acid and lactoferrin (LF), as well as protein, fat and lactos

Warum können wir Fahrrad fahren

Beim Fahrradfahren arbeitet der Mensch als Regler. Das wird beim Balancieren des Fahrrades besonders offensichtlich, denn das Fahrrad ist instabil. In diesem Beitrag wird untersucht, unter welchen Bedingungen es möglich ist, das Fahrrad mit einem so einfachen Reglergesetz zu balancieren, dass Menschen dieses Reglergesetz ohne Mühe realisieren können. Dabei wird nicht nur die jedem Radfahrer bekann

Body mass index as a predictor of fracture risk: A meta-analysis

Low body mass index (BMI) is a well-documented risk factor for future fracture. The aim of this study was to quantify this effect and to explore the association of BMI with fracture risk in relation to age, gender and bone mineral density (BMD) from an international perspective using worldwide data. We studied individual participant data from almost 60,000 men and women from 12 prospective populat

Theory, boundaries and political communication - The uses of disparity

While the themes of fragmentation and insufficient coherence dominated discussions in the field of media and communication studies a decade ago, today they seem less urgent, even if at times still problematic. In terms of theory, the field is well served by its permeable boundaries, since much of its theory is 'imported'. Moreover, theory needs nondoctrinaire critical stances to address the distre

The GSSP of the second (Upper) stage of the Lower Ordovician series: Diabasbrottet at Hunneberg, province of Vastergotland, southwestern Sweden

Diabasbrottet, selected by the International Subcommisson on Ordovician Stratigraphy and in 2002 ratified by the International Commission on Stratigraphy as the GSSP of the Second (Upper) Stage of the Lower Ordovician, is located on the Hunneberg Mountain in southwestern Sweden. The stratigraphic succession represents an outer shelf environment near the Baltic Shield margin. The shale-dominated, b

System Identification using LQG-Balanced Model Reduction,

System identification of linear multivariable dy-namic models based on discrete-time data can be performed using a algorithm combining linear regression and LQG-balanced model reduction. The approach is applicable also to unstable system dynamics and it provides balanced models for optimal linear prediction and control.
