Popular Abstract in Swedish Denna avhandling handlar om modeller för plana solfångare, transparent isolering och verkningsgradsfaktorer. En ekvation för energiutbytet från en glasad plan solfångare härleds genom att modellera verkningsgradsfaktorn, F´, som en summa av en konstant och en temperaturberoende del. Ett alternativt sätt att testa en plan solfångare, baserat på denna modell, föreslås. EThis thesis deals with models of flat plate collectors, transparent insulation and efficiency factors. An equation for the energy output from a glazed flat plate collector is derived by modelling the collector efficiency factor, F´ as the sum of a constant and a temperature dependent part. An alternative way of testing a flat plate collector, based on this model, is suggested. A complete set of a

Increasingly, buildings are becoming complex “systems of systems” with many materials and attributes combining to create a whole that aims to meet a variety of design objectives including but not limited to functionality, aesthetic appeal, sustainability, safety, and security. We are now seeing this complexity move from commercial buildings and iconic structures to encompass even the residential s

Background and AimsOlder persons with problematic alcohol use vary in psychosocial functioning, age of onset for problem drinking and use of other drugs. The study measured the differential risks of all-cause, alcohol, polydrug and psychiatric-related repeated hospitalizations among older persons with problematic alcohol use.DesignA linked register-based cohort study with discontinuous multiple-fa

2593Background: PD-1 blockade has demonstrated positive anti-tumor activity across multiple tumor types. While the anti-tumoral response can be substantial and even curative, response rates remain low in many cancer types. Long-lasting responses are only observed in a minority of patients, and additional immunotherapeutic alternatives remain limited for patients who fail to respond or initially re

The lysosomal cysteine proteinase cathepsin B is shown to be secreted by ten human colon carcinoma cell lines and to accumulate in culture media as a latent enzyme. The cell lines also secrete a physiological inhibitor of cathepsin B, cystatin C. A significant correlation was found between secretion of the latent enzyme and the inhibitor (r = 0.755, P < 0.01). The aim of the present study was to m

Background/aims It is unclear whether a reduction in tear secretion contributes to the discomfort experienced by those with prosthetic eyes. Tear secretion has hitherto only been measured with the Schirmer test which may be affected by the pooling of tears behind the prosthesis. In this study, direct imaging of the lacrimal gland has been performed to measure tear secretion in anophthalmic sockets

This thesis presents a comprehensive systems analysis of the impact of quality assessments, communication practices, and monitoring mechanisms on the efficiency of public procure-ment in the Swedish construction sector. Recognizing that public procurement is a corner-stone for societal infrastructure and development, the study specifically examines procure-ment regulated by the Swedish Public Proc

Sweden has during the past decades experienced increasing challenges in suburban, segregated areas: the inhabitants have different cultural and socio-economic backgrounds but despite that, face similar problems. Many inhabitants lack relevant networks as well as other opportunities to become a part of the society. These inhabitants claim they don´t have the “keys” to understand their society and iSweden has during the past decades experienced increasing challenges in suburban, segregated areas: the inhabitants have different cultural and socio-economic backgrounds but despite that, face similar problems.

This study examines the experiences of four women being a part of a separatist space for women and transgender people creating music digitally and working with music production. For the four informants, the separatist context has been perceived as a safe space. Through interviews we find out about the informants' different experiences. All four feel that they have been strengthened by having b

Personlig integritet är ett begrepp som har fått en allt viktigare innebörd i arbetslivet de senaste åren. Frågan om drogtesters plats i arbetslivet är en av de mest framträdande frågorna, då det av många anses vara en kränkning av den personliga integriteten. Det är därför av stor vikt att bedöma när och för vilka syften ett drogtest kan anses vara befogat. Det uppstår därmed en situation där arb

Background: Asphalt workers are exposed to polyaromatic hydrocarbons (PAHs) from hot mix asphalt via both inhalation and dermal absorption. The use of crumb rubber modified (CRM) asphalt may result in higher exposure to PAHs and more adverse effects. Our aim is to assess occupational exposure to PAHs from conventional and CRM asphalt paving by measuring PAH metabolites in urine, and to investigate
