Cryptochromes (Cry) have been suggested to form the basis of light-dependent magnetic compass orientation in birds. However, to function as magnetic compass sensors, the cryptochromes of migratory birds must possess a number of key biophysical characteristics. Most importantly, absorption of blue light must produce radical pairs with lifetimes longer than about a microsecond. Cryptochrome 1a (gwCr

For the production of basic materials a deep decarbonization fundamentally requires the development of new process technologies. However, the climate policies currently adopted in G8 countries mainly reward incremental improvements and preserve industrial structures rather than induce innovation and preparations for a low-carbon transition. The current policy approach is motivated by fear of carbo

I antologin In Tension between Organization and Profession diskuterar en rad svenska och skandinaviska forskare olika vardagsproblem som individer i offentlig verksamhet upplever. Varför tycks sjukfrånvaro och utbrändhet ständigt öka samtidigt som resurserna inom offentlig sektor blir allt mindre? Är det förresten en bild som stämmer? I denna antologi sätts individen i centrum; det är individens r

The authors of the best-selling book PID Controllers: Theory, Design, and Tuning once again combine their extensive knowledge in the PID arena to bring you an in-depth look at the world of PID control. A new book, Advanced PID Control builds on the basics learned in PID Controllers but augments it through use of advanced control techniques. Design of PID controllers are brought into the mainstream

Dendritic cells (DC) are a heterogeneous lineage of bone-marrow-derived leukocytes that serve as the link between innate and adaptive immunity. They are professional antigen-presenting cells that play an important protective and regulatory role in both health and disease. This thesis is based upon six original papers that deal with the function and transcription of human DCs, with focus on their r

Popular Abstract in Swedish Utifrån epigrafiska källor analyserar avhandlingen Afrodites roll som ämbetsmannabeskyddarinna. Huvudmaterialet är 62 dedikationer till Afrodite: inskrifter från ämbetsmän eller dedikationer där gudinnan presenteras med ett epitet som alluderar på ett ämbete, t.ex. Afrodite Strategis, ‘Strategernas Afrodite’. Materialet visar att Afrodite dyrkades av ämbetsmän på ett paThrough the identification of a series of inscriptions, mainly datable to the Hellenistic era, a link between Aphrodite and the civic life and administration of the Greek poleis has come to light. The inscriptions in question are dedications to Aphrodite through which magistrates of various cities and varying status express their devotion to the goddess. In certain dedications, the goddess is even

While there is a growing body of psycholinguistic experimental research on mappings between language and vision on a word and sentence level, there are almost no studies on how speakers perceive, conceptualise and spontaneously describe a complex visual scene on higher levels of discourse. This book explores the relationship between language, eye movements and cognition, and brings together disco

Semiconductor nanowires are nanoscale objects formed by bottom-up synthesis. In recent years their unique properties have been exploited in fields such as electronics, photonics, sensors and the life sciences. In this work, the epitaxial growth of nanowires and their applications were studied. Heteroepitaxial growth of III-V nanowires on silicon substrates was demonstrated. This may enable direct

This article examines five arguments often used in scriptural hermeneutics (see, e.g., C. H. Cosgrove, Appealing to Scripture in Moral Debate: Five Hermeneutical Rules) and analyses in what way they are applied in the contemporary debate on homosexuality: (1) countercultural arguments,(2)analogies,(3) nonscientific scope,(4) purpose, and (5) the canonized pluralism in the Bible.

All service control nodes, for example SCPs, HLRs, and MSCs, are constructed as a server system with one or more servers that process incoming requests. Since service control nodes are sensitive to overload, admission control mechanisms are often implemented. In this paper, we model and analyse admission control mechanisms for server systems with control theoretic methods. We develop a nonlinear s
