Fuel ethanol can be produced from lignocellulosics by an enzymatic process consisting of steam pretreatment, enzymatic hydrolysis, fermentation and ethanol refining. This thesis deals with the steam pretreatment step in the enzymatic process used for ethanol production from softwood, which is an abundant lignocellulosic raw material in the Northern hemisphere.Steam pretreatment is an effective met
Phosphodiesterase (PDE) isoenzymes have been shown to play a role in the control of human male genital tissues. There are hints from basic research and clinical studies that PDE5 inhibitors may have the ability to retard the male ejaculatory response. While the expression of PDE isoenzymes in the human seminal vesicles (SVs) has been described, the distribution of cyclic adenosine monophosphate (A
TnBgl1A from the thermophile Thermotoga neapolitana is a dimeric beta-glucosidase that belongs to glycoside hydrolase family 1 (GH1), with hydrolytic activity through the retaining mechanism, and a broad substrate specificity acting on beta-1,4-, beta-1,3- and beta-1,6-linkages over a range of glyco-oligosaccharides. Three variants of the enzyme (TnBgl1A_E349G, TnBgl1A_E349A and TnBgl1A_E349S), mu
Popular Abstract in Swedish Kunskapsarbete framställs ofta som något som präglas av dolskhet eller oklarhet: produkten som säljs är oklar, resultatet är oklart och även själva arbetsprocesserna framställs ofta som oklara. Detta påverkar i sin tur den styrning som man kan förvänta sig i kunskapsintensiv verksamhet: en styrning som ofta handlar om personalen mer än om arbetet. I denna studie problemKnowledge work is often portrayed as hidden or ambiguous: an ambiguous product is sold, ambiguous results are delivered, and work processes are ambiguous. This in turn affects the type of management expected in knowledge-intensive organisations, where emphasis is on managing people rather than work. In this study, the organisation of knowledge work is discussed and problematized through analysis o
I slutet av 90-talet utvecklades produkten korslimmat trä, KL-trä. Framtagningen av KL-trä var ett projekt för att framställa ett byggnadsmaterial med avseende att kunna konkurrera med betongindustrin och därigenom bidra till en lägre miljöpåverkan, då trä har en låg påverkan på miljön i förhållande till många andra konstruktionsmaterial. KL-träelement är vanligtvis konstruerade som plattor och haIn the late 1990s cross-laminated timber (CLT) was developed. The development of CLT was a project aimed to produce a structural product that could compete with the concrete industry and contribute to a reduced effect on the environment, due to the low environmental impact of timber in relation to other building materials. CLT elements are usually constructed as panels which contain multiple layer
Background: Exposure to particulate matter (PM) is generally associated with elevated risk of cardiovascular morbidity and mortality. Elderly and obese subjects may be particularly susceptible, although short-term effects are poorly described. Methods: Sixty healthy subjects 25 males, 35 females, age 55 to 83 years, body mass index > 25 kg/m(2)) were included in a cross-over study with 5 hours of
The Dahra field site in Senegal, West Africa, was established in 2002 to monitor ecosystem properties of semiarid savanna grassland and their responses to climatic and environmental change. This article describes the environment and the ecosystem properties of the site using a unique set of in situ data. The studied variables include hydroclimatic variables, species composition, albedo, normalized
Inflammatory myofibroblastic tumor (IMT) is a neoplasm composed of myofibroblastic spindle cells and infiltrating inflammatory cells. Cytogenetic analyses have revealed that a subgroup of IMT, in particular among children and young adults, harbors clonal chromosomal rearrangements involving chromosome band 2p23. Further, molecular genetic studies have shown that these rearrangements target the ALK
Spatial relationships are a comprehensive and essential part of geographical information management and GIS. Topological relationships are a subgroup of the spatial relationships. They are defined by the fact that they do not break under topological transformations, meaning they remain when stretching, twisting or crumbling the underlying space. Topological relationships are for instance relations
This report describes the development of a manufacturing process for creating custom-made prosthetic arm sockets using 3D scanning and 3D printing. The process is intended to function as a guide for a prosthetist without requiring an extensive experience in CAD. The project aims to offer a viable alternative to the often time consuming and manual labour-intensive conventional manufacturing method,
A methodology for estimating the carbon balance across Scandinavian forests using remote sensing is presented. By estimating the gross primary production (GPP) and the ecosystem respiration (ER), and thereby, the net ecosystem exchange (NEE), using parameters that are routinely retrieved from satellite, it is possible to implement an operational model for obtaining large scale NEE. GPP is successf
Pursuit of the Bioeconomy (BE) and the Circular Economy (CE) is high on the political agendas of many countries. Application of the concepts is intended to ameliorate a number of sustainability challenges, such as raw material constraint concerns and global warming. The concepts of BE and CE are increasingly combined to describe a ‘circular bioeconomy’ (CBE), which emphasises value retention for r

Barnahus syftar till att förbättra utredningar och samarbete mellan myndigheter när barn misstänks ha varit utsatta för brott som misshandel eller sexuella övergrepp. I Barnahus samverkar olika instanser som socialtjänst, polis, åklagare, barnmedicin, rättsmedicin samt barn- och ungdomspsykiatri i en barnvänlig miljö. I stället för att behöva upprepa sin berättelse för olika tjänstemän på olika plBarnahus in Sweden exist to improve investigations and the collaboration between public agencies when children are suspected being victims of physical and/or sexual abuse. Barnahus are multi-agency collaborations that bring together local authority child welfare services, the police, public prosecutors, paediatric medicine, forensic medicine, and child- and adolescent psychiatry in a child-friendl
Social interaktion sker ofta i grupper. För barn är skolklassen en grupp de dagligen interagerar i. Skolklassen och den sociala interaktion som sker i skolan har stor betydelse för barns välmående och framtida sociala interaktioner. Lärarna i skolan har därför i uppdrag att arbeta med barns sociala samspel och mot kränkande behandling. Avhandlingens övergripande syfte att öka förståelsen för barnsSocial interaction often takes place in groups. The school class is an important group in which children interact. Children spend a large percentage of their day with their classmates in school and classmates are not only co-workers, but also individuals interacting socially as friends. Several studies show that social interaction and friendship in school effect children’s wellbeing, academic perf
Methanol is a promising renewable fuel that can be used to reduce the carbon intensity of internal combustion engines. In any combustion strategy with methanol, both unburned methanol and formaldehyde emissions are criteria pollutants that are potential drawbacks, so their accurate measurement is critical. The flame ionization detectors (FIDs) typically used in engine research to measure unburned
The radioactive noble gas radon (222Rn) is a suitable tracer for atmospheric transport and mixing processes that can be used to evaluate and calibrate atmospheric transport models or to estimate greenhouse gas (GHG) emissions using the so-called radon tracer method (RTM). However, these applications require reliable estimates of the 222Rn fluxes from the soil. This study evaluates two process-base
Circular economy (CE) is still a nascent research field in the built environment, however, has gained traction in the last decade. Despite it being generally accepted that sustainability consists of three dimensions, namely, social, environmental, and economic, CE has been criticised for focusing on environmental and economic impact whilst neglecting the social aspect. Further, CE has been critici
