In a dispatchable wind power plant, turbines are free to continuously vary their power production as long as the sum of their productions meets the total power demand. Previous research has shown that this freedom can be used to reduce structural loads by allowing turbines in the plant to coordinate their power. This paper explains the mechanisms that make power coordination useful for reducing st

We have examined concurrent and prospective validity of an index of self-reported walking (RW) of 307 home-dwelling women aged 75 years and above, of whom 155 in 1 year had in all 308 falls of which 13% resulting in fractures. It consists of five items concerning various aspects of self-reported walking identified by factor analysis. The sum score on this ''RW-index'' correlated moderately ( r = 0

Modern media messages are visually fragmented since they are built up of various visual elements and units (Holsanova & Nord, 2010). This tendency has also been described as atomization of news texts (Knox, 2007) or as modularization of the text design (Bucher, 2000). Media messages are also multimodal in the sense that they contain delimited parts of text (articles, headlines, briefs, lists o

Popular Abstract in Swedish Avhandlingen studerar tillväxtfaktorernas reglering av uPA-systemet i endometriet, och betydelsen av uPA-receptorns (uPAR) aktivering i den endometriella angiogenesen. Tillväxtfaktorer är polypeptider, vilka fungerar som signalmolekyler i cellernas kommunikation. Tillväxtfaktorerna frisätts från sina ursprungsceller och binder sig till specifika receptorer på ytan av ceThe purpose of this thesis was to examine the role of growth factors and the urokinase plasminogen activator (uPA) system in human endometrial angiogenesis. Growth factors as well as progesterone increased expression of the main inhibitor of uPA (PAI-1) in primary cultures of endometrial stromal cells. EGF, TGF-beta1 and bFGF increased gene transcription whereas progesterone increased mRNA stabili

Popular Abstract in Swedish Hur begreppet religion kan klargöras eller definieras är en mycket omtvistad fråga inom åtskilliga akademiska discipliner. Två huvudsakliga negativa tendenser är märkbara inom gängse och aktuell teoribildning. För det första har det framkastats en mängd divergerande definitionsförslag under årens lopp. Detta har bland annat lett till en teoretisk uppgivenhet inför uppgiIt is a contested question in contemporary theories of religion whether the concept of religion can be defined in a sound way or not. Many theorists maintain that a universal but delimiting definition is impossible. In this study, by contrast, it is argued that a conceptual analysis of religion that holds universally is perfectly possible because the following thesis can be seen as a necessary and

In this paper we define a many-valued semantics for hybrid logic and we give a sound and complete tableau system which is proof theoretically well-behaved, in particular, it gives rise to a decision procedure for the logic. This shows that many-valued hybrid logics is a natural enterprise and opens up the way for future applications.

During the last 15 years questions concerning gender, technology and knowledge, have become increasingly recognized as central to the field of the sociology of technology. Nonetheless, critical questions remain unanswered. These issues are addressed here through investigations of the relationship between gender, work, knowledge and technology. This thesis is composed of an introduction and four in

"What lies hidden behind online ads for erotic services, or on streets on the outskirts of cities, or in the downtown apartments used by escorts? What is someone who buys sex risking? What can be done to prevent human trafficking? What rights to sex workers have? Why is it that Germany considers prostitution to be a service, while Sweden punishes it as one of the most shameful forms of violence ag
