Gång på gång möter den som oroar sig för risker expertrådet att lära sig att skilja mellan fara och risk. Ofta diskuteras nämligen faror som innebär mycket små risker, men det förstår allmänheten inte. Mycket av vår oro för risker beror på ett enkelt misstag. Det här kapitlet visar dock att det inte är så lätt att skilja mellan fara och risk, åtminstone inte enligt de gängse distinktioner som expe

Popular Abstract in Swedish "Becoming Muslim" är en etnologisk studie som baserar sig på djupintervjuer gjorda med sex svenska respektive tre amerikanska kvinnor vilka konverterat till islam. Utifrån deras livsberättelser studeras konversionsberättelsen (kap. 3), den kognitiva formationen av en muslimsk identitet (kap. 4) samt möten med det omgivande samhället (kap. 5). I avhandlingen ligger fokus"Becoming Muslim: Meanings of Conversion to Islam" is an ethnographic study analyzing the identity-making of female Muslim converts. It is based on eighteen in-depth interviews with six women in Sweden and three women in the U.S. The process of becoming Muslim is explored by looking at the conversion narrative, the cognitive organization of a Muslim identity, and encounters with the surrounding wo

Long-term instability in multiplanet exosystems is a crucial consideration when confirming putative candidates, analysing exoplanet populations, constraining the age of exosystems and identifying the sources of white dwarf pollution. Two planets that are Hill stable are separated by a wide-enough distance to ensure that they will never collide. However, Hill-stable planetary systems may eventually

This paper considers off-line optimization of a switching sequence fora given finite set of linear control systems and joint optimization ofcontrol laws. A linear quadratic full information criterion isoptimized and dynamic programming is used to find the optimalswitching sequence and control laws. The main result is a method for efficient pruning of the search tree to avoid combinatoric explosion

Popular Abstract in Swedish Vårt behov av att öka matproduktionen för en växande global befolkning, har sedan mitten av nittonhundratalet drivit jordbrukets utveckling. Det traditionella, småskaliga jordbrukslandskapet med sitt lapptäcke av betesmarker, ängar och åkrar, har över tid ersatts av ett mer produktionsinriktat landskap. Åkrar har slagits ihop för att skapa större odlingsenheter, där nyaThe intensification of agriculture during the second half of the twentieth century, has caused sever declines of farmland biodiversity, where loss of semi-natural habitats is one of the major drivers. To halt further loss of habitat and biodiversity, agri-environmental schemes (AES) are used to compensate farmers to use methods less harmful to the environment. In this thesis, I have investigated t

We have studied the state of Cyt b559 and the Mn cluster by EPR and optical spectroscopy in the different S-states between pH 4.0-10.0. In these experiments, the pH was changed after the OEC turnover to the appropriate S-state (at pH 6.0) by 0-3 saturating flashes. Furthermore, the state of Cyt b559 after a subsequent flash given after the pH modification was also investigated. The results show th

The modern consumers live in a transparent world with unlimited information and consumers adopt information strategies around who they trust and this is based on their values and experiences of food. Consumer question the information provided by the authorities and seek other sources of information such as the Internet and fellow consumers. There is a need for this consumer perspective in value ch

Popular Abstract in Swedish Vävnadsförändringar förekommer i många normala tillstånd, antingen gradvis som i åldrande eller mer drastiskt vid till exempel sårläkning, fosterutveckling och förlossning. Dessa vävnadsförändringar är viktiga, men det finns tillfällen då vävnadsförändringar är assoscierade med sjukdomar. Exempel på sådana sjukdomar är utvecklandet av cancer eller fibrotiska tillstånd sTissue remodeling is observed in several physiological conditions such as embryogenesis, senescence, wound healing and pregnancy, as well as in several pathological conditions such as fibrosis and tumorgenesis. Fibroblasts play a key role in this tissue remodeling due to their capability of altering the turnover of the extracellular matrix. During the remodeling process, the fibroblasts are believ
