In the last decades, the growing competitiveness of the market has continuously driven the forming companies to highly optimize their products regarding offered performance at minimum cost. In order to achieve better products, studies where conducted with different material models when simulating the forming process of titanium. The material is often used in heat exchanger applications. Titanium h
2014 års Demokratiutredning har i uppgift att analysera behovet av och utarbeta förslag till åtgärder för att öka och bredda engagemanget inom den representativa demokratin. Utredningen ska även föreslå åtgärder i syfte att stärka individens möjligheter till delaktighet i och inflytande över det politiska beslutsfattandet mellan de allmänna valen. En särskild uppgift för utredningen är att belysa
Popular Abstract in Swedish Även om vi befinner oss i en tidsepok av informationsteknologi och superdatorer så utförs dagens forskning baserat på Galileos vetenskapliga principer. Trots det så finns det idag inget behov av att klättra upp i det lutande tornet i Pisa för att observera hur ekvationerna för rörelse, enligt den klassiska mekaniken, tar sig uttryck för fallande kroppar. Samma experimenRecent years have witnessed a growing interest of the scientific community for the use of ab initio and density functional theory methods in theoretical studies of molecules containing many atoms. However, the `scaling wall' of some of the most accurate of such methods is often an obstacle for their applicability to systems of real-life interest, e.g. in biochemistry and nanotechnologies, one bott
Avsikten med detta projekt har varit att utveckla väl fungerande rutiner för PIXE-analys av biologiska prov med anknytning till exponering i arbetsmiljösituationer. Kravet på metoderna är att de tillvaratar PIXE-metodens fördelar (multielementanalys, små prov, snabb analys, låga detektionsgränser) och samtidigt förändrar eller förstör så lite som möjligt av den information som finns i de ursprungl
The concept of a holistic innovation policy is defined in this article, with discussions of what it is, why it is relevant, and how it can be implemented to enhance product innovation. It is shown that the innovation systems approach has diffused rapidly during the latest decades and has completely replaced the linear view in the field of innovation research. The majority of European countries are
Why is waste such an important topic for understanding the management of overflow? First, because waste is a classic symbol of overflow: to be flooded with too much stuff that demands handling, sorting, and decision-making is a feeling well known in consumer society. Facts and figures speak of the same overflow. Waste disposal is a growing problem. The downside of consumption is a growing mountain
Numerous products from the food industry contain fruit and/or berries, in the form of fillings or ingredients, e. g. in yoghurt, some bread products/cereal products, ice cream, etc. In order to produce these ingredients and improve their characteristics, many processing techniques are available. This thesis focuses on dehydration methods that take into account the fragile and complex cellular tiss
With the exponential growth of the World Wide Web, automated subject classification of Web pages has become a major research issue in information and computer sciences. Organizing Web pages into a hierarchical structure for subject browsing is gaining more recognition as an important tool in information-seeking processes. In this thesis, different automated classification approaches, focusing on
A discussion on Suzanne Osten's film Bröderna Mozart, as a non-typical Swedish film of its period.
Popular Abstract in Swedish Syftet med den här studien var att undersöka det strukturella underlaget för förslagen att makrofager och gaserna kvävemonooxid (NO) och kolmonoxid (CO), som bildas av kvävemonooxidsyntaser (NOS) respektive hemeoxygenaser (HO), är viktiga för att en perifer nerv ska regenerera. Det finns stöd för dessa hypoteser eftersom andra har visat att förhållanden som stör den invThe purpose of this study was to investigate the suggestions that macrophages, and the systems generating nitric oxide (NO) and carbon monoxide (CO), i.e. nitric oxide synthases (NOS) and heme oxygenases (HO), could be important for peripheral nerve regeneration. Immunocytochemistry was used to visualise invading and resident macrophages, inducible NOS (iNOS), two isoforms of HO (HO-1 and HO-2),
Many vertebrate animals are known to have multiple sites for photoreception that are not involved in vision. Extraretinal photoreception is indicated to play a crucial role in early development, physiology and behavior, as well as in later biological processes. This thesis encompasses four studies investigating the neuromorphological, neurochemical and molecular basis for extraretinal photosensiti
