Drugs prepared from organic and mineral substances have, throughout history, held a central position when it comes to preventing and curing disease. In Galenic medicine, foodstuffs, drugs and deadly substances, or poisons, were all accredited with the potential to affect the constitution of the body. While the Galenic paradigm continued to dominate formal medicine in the Middle Ages, the language

Popular Abstract in Swedish Till ryggmärgen kommer känselinformation om vad som händer med kroppen. Denna information använder vi sedan för att kunna korrigera våra rörelser. Många av dessa korrektioner utförs mer eller mindre självständigt av nervkretsar belägna i ryggmärgen. Att snabbt omvandla dessa känselsignaler till muskelaktivitet är oerhört komplicerat och beräkningskrävande eftersom kroppDuring development, information about the three-dimensional shape and mechanical properties of the body is laid down in the synaptic connectivity of sensorimotor systems through adaptive mechanisms. In spinal reflex systems, this enables the fast transformation of complex sensory information into adequate correction of movements. In this thesis, it is shown, in a computer simulation, that an unsup

Wind has a profound influence on migrating birds since it inevitably will influence travel time and energy expenditure. In this thesis I investigate how migrating birds are affected by, and use winds. The studies cover the following main topics: i) the influence of wind on the decision to depart on a migratory flight, and possible energy savings by choosing to migrate in tailwinds, ii) the effect

The principles for today's international refugee policies were laid down in the years following World War II, with the creation of the UNHCR and the establishment of an international refugee convention. These years, which were the central phase in the development of a new refugee regime, are the topic. The refugee question is set in an East-West perspective. The rethoric of refugee policies is con

Popular Abstract in Swedish De fettlösliga vitaminerna upptäcktes i början av 1900 talet, och indelas i klasserna A, D, E och K. Brist på vitaminer i kroppen kan leda till svåra sjukdomar som nattblindhet, benskörhet och cancer. Även en överdos kan vara mycket allvarlig, och därför finns det bestämmelser om vilka livsmedel som ska vitaminberikas samt med hur mycket av varje vitamin. Dessutom utförSample clean-up methodologies based on supercritical fluid extraction (SFE) have been developed for determination of fat-soluble vitamins in foods. This thesis focuses on method development, stressing important issues concerning sample pre-treatment, extraction conditions and collection parameters. It was demonstrated that by using SFE followed by saponification and determination using RP-HPLC wit

This book chapter discusses Meret Oppenheim's art as a central contribution to European modernism, and provides a critique of the male dominated art history writing.

In this paper I give a short presentation of a syntactic approach to argument structure, taking a particular implementation of the minimalist framework (Chomsky (1995, 2001 and later)) as my point of departure. The proposed account allows for only 16 different argument structures, thereby reducing the syntactic variation at this level of syntax considerably. The theory also offers an explanation w

THESE EXERCISES SERVE THE PURPOSE OF TRAINING THE UNDERSTANDING OF SEVERAL BASIC CONCEPTS IN ELEMENTARY UNIVERSITY-LEVEL MECHANICS. WHEREAS MECHANICS IS OFTEN TAUGHT AS A COURSE WHERE “PEN AND PAPER” ARE THE ONLY TOOLS, THESE EXERCISES ATTEMPT TO PROVIDE KNOWLEDGE ON HOW THE BASIC THEORY WORKS, ON PRACTICAL PROBLEMS, BY USING A MODERN SIMULATION COMPUTER SOFTWARE. BY SIMULATIONS THE GENERAL PERFOR
