Upregulation of p75 neurotrophin receptor after stroke in mice does not contribute to differential vulnerability of striatal neurons
User related assessment of Continuous Support & Curve Speed Control (FFA)
The aim of the user related assessment was to study perceived advantages, disadvantages, usefulness, trust, acceptance, willingness to have and pay for the driver assistance system: Continuous Support & Curve Speed Control developed by FFA within the framework of the SECONDS subproject. Due to restrictions in driving in real traffic, assessment activities were limited to driving on a test trac
Production of Ethanol from Spruce at High Solids Concentrations - An Experimental Study on Process Development of Simultaneous Saccharification and Fermentation
Popular Abstract in Swedish Intresset för förnybara bränslen har ökat stadigt under de senaste åren. Att byta ut fossila mot förnybara bränslen kan minska utsläppen av växthusgaser till atmosfären och därmed minska klimatpåverkan av dessa men även minska vårt beroende av olja. Biobränslen som t.ex. etanol, biodiesel eller biogas, räknas till förnybara bränslen eftersom de inte bidrar till en ackumReplacing fossil fuels by biofuels such as ethanol is considered a promising alternative to reduce greenhouse gas (GHG) emissions and mitigate climate change. Biofuels produced from lignocellulosic biomass, so-called second generation biofuels, result in decreased GHG emissions and limit competition with food and animal feed production. Interest in producing ethanol from lignocellulosic biomass ha

Empirical Essays on Financial Economics
In the first essay of this thesis we develop a model for calculating the net expected value of a swap agreement subject to dual-default risk. The main explanatory variable for the net expected return of a swap is the default intensity of each party measured by the credit rating of the firm. We derive the net expected return of the swap as a function of the credit rating of the firm receiving the f
Dose dependence of mass and microcalcification detection in digital mammography: free response human observer studies.
The purpose of this study was to evaluate the effect of dose reduction in digital mammography on the detection of two lesion types-malignant masses and clusters of microcalcifications. Two free-response observer studies were performed-one for each lesion type. Ninety screening images were retrospectively selected; each image was originally acquired under automatic exposure conditions, correspondin
Rethinking GIS, three-dimensionality and space perception in archaeology
For over 30 years GIS has been a major theme in archaeology, leading scholars to debate the way geo-spatial platforms can contribute to a better understanding of the ancient landscape and a more thorough interpretation of the archaeological record. Recently, the introduction of more advanced software and hardware solutions have made it possible to use GIS for visualizing and analysing even geometr
Denitrification at low temperatures using a suspended carrier biofilm process
The denitrification process was studied in a stirred lab-scale suspended carrier biofilm reactor at low temperatures (3–20°C). The reactor was filled to 50% with Kaldnes K1 carriers. The denitrification rate showed only a rather weak dependence on the temperature, the rate at 3°C being approximately 55% of that at 15°C. The maximum denitrification rate obtained at 15°C was 2.7 g NOx−-N m−2 carrier
Med främmande bagage : Tankar och erfarenheter hos unga människor med ursprung i en annan kultur eller Det postmoderna främlingskapet
Popular Abstract in Swedish Allt fler ungdomar i vårt land, liksom i många andra länder, lever i vardagen med mer än en kultur. En femtedel av eleverna i den svenska skolan är antingen själva födda i ett annat land eller har minst en förälder med utländsk bakgrund. För många av dessa barn och ungdomar har därför inte samhällets dominerande kultur funnits med från början av deras liv. Bekantskapen The present study is based on interviews with 22 youth and young adults. The perspective is phenomenological, since my aim has been to analyse and describe the everyday world as it presents itself to these young people. A process begins in the encounter with the majority culture and the emphasis is on how they think about events and experiences along the road to a more complex life-world. The proc

Deposition of Airborne Particles onto the Human Eye - Wind Tunnel Studies of the Deposition Velocity onto the Eyes of a Mannequin
Abstract In the field of occupational hygiene much consideration is devoted to the uptake through the human airways, but there are also reports of irritations, complaints and hazards or potential hazards due to particle deposition onto the eyes. There is a need for data regarding the dependence of the deposition rate on particle size and environmental parameters in order to formulate sampling crit
Using simulation to analyse the impact of software requirement volatility on project performance
During the last decade, software process simulation has been used to address a variety of management issues and questions. These include: understanding; training and learning; planning; control and operational management; strategic management; process improvement and technology adoption. This paper presents a simulation model that was developed to demonstrate the impact of unstable software requir
Vägval 2050: Styrningsutmaningar och förändringsstrategier för en omställning till ett kolsnålt samhälle
Today there are climate policy targets within the EU and Sweden about limiting global warming and drastically reducing greenhouse gas emissions. In order to stay within the goal of a global warming of less than 2 ºC, the industrialised countries should decrease their emissions by 80-95 % in 2050, and bring them down to zero in the longer run. Scenario studies indicate that this is possible to achi
Verification of sheet metal forming simulation of advanced thin plate parts using a first order friction model
There is today a need of better prediction of part geometry regarding industrial products by simulations. There is a need for better prediction of material inflow, stresses and strains and final geometry. One way to solve this could be by using a more advanced friction model. Today a zero order friction model (Coulomb friction) is normally used. By using a friction model of higher order the fricti
Hegemony and the Intellectual Function : Medialised Public Discourse on Privatisation in Sweden 1988-1993
This dissertation offers a theorisation of the ways in which the intellectual function is performed through various subject positions. In the thesis, a post-Marxist approach to discourse theory is used to address questions of discursive shifts, hegemony and the intellectual function. It is supplemented by a rhetorical political analysis in order to examine how practices and strategies involved in
Pankreascancer kan metastasera tidigt : Tumörbiologi tycks viktigare än tumörstorlek
Pancreatic cancers are associated with poor survival and only some 10 per cent are resectable, but even in this subgroup recurrence is very frequent. The traditional view of sequential development of pancreatic cancer has been challenged by novel molecular biological findings, where the tumor quite rapidly might turn metastatic. In about 60 000 patients with diagnosed pancreatic cancer the associa
Viscosity Model Uncertainties in an Ash Stabilization Batch Mixing Process
Recycling wood ash from burnt wood (back to the forest grounds) is of great ecological importance. However, the ash cannot be recycled directly after combustion. There are several reasons for this, one being the volatility of wood ashes. Mixing ash/dolomite/water in order to obtain granular material is one method to stabilize wood ashes. The main problem is predicting the quantity of water to be a

The Prohibition of Dismissal in Sweden and Germany: A Comparative Study of the Scope of Article 4.1 in the Transfers of Undertakings Directive
This study aims to clarify the current state of the law regarding the prohibition of dismissal in the context of transfers of undertakings in Sweden and Germany. The prohibition of dismissal originates from Article 4.1 of the Transfer Directive (2001/23/EC) and is an integral part of the European Union’s employment protection framework, primarily aimed to protect employments by restricting dismiss
