Popular Abstract in Swedish 2003 års Nobelpris i kemi gick till professor Peter Agre för upptäckten av aquaporinerna. Aquaporiner är proteiner som sitter i membran och bildar kanaler som tillåter vatten och andra små neutrala molekyler att passera genom membranet. Aquaporinerna utgör en mycket gammal och välkonserverad proteinfamilj som finns i alla levande organismer som hittills undersökts. VäxAquaporins, or Major Intrinsic Proteins (MIPs), are integral proteins that facilitate transport of water and other small neutral solutes across biological membranes. They belong to a well conserved and ancient family of proteins, present in all organisms ranging from bacteria to plants and humans. The aquaporin family in plants is large, indicating complex and regulated water transport within the

There is today a need of better prediction of part geometry regarding industrial products by simulations. There is a need for better prediction of material inflow, stresses and strains and final geometry. One way to solve this could be by using a more advanced friction model. Today a zero order friction model (Coulomb friction) is normally used. By using a friction model of higher order the fricti

Abstract in German Der Widerstand in den evangelischen Kirchen Europas 1933-1945 ist ein komplexes Problem. In vielen Kirchen wurde er gegen die nationalsozialistische Ideologie oder die deutsche Besetzung geleistet. Jedoch kann das Problem nicht auf den Widerstaned gegen den Nationalsozialismus begrenzt werden. Kirchlichen Widerstand gab es auch gegen den Sowjetkommunismus, wie in Estland und Let

Adsorption dynamics of various types of uncharged homopolymers onto solid surfaces in good solvent have been studied by using a coarse grained bead-spring model. Brownian dynamics simulation has been used to examine the adsorption process for polymers released near an adsorbing surface, and Monte Carlo simulations have been employed to explore equilibrium properties of adsorbed polymers. Two diff

A numerical investigation has been carried Out for the turbulent fluid flow and heat transfer in periodic fully developed corrugated ducts. Three turbulence models are used in the calculation: the standard k - epsilon model, the Re-Normalized Group (RNG) k - epsilon model and a Reynolds Stress Model (RSM). The turbulent heat flux is modeled by the simple eddy diffusivity model (SED). The numerical

Although the research on the design of heterogeneous concurrent systems has a long and rich history, a unified design methodology and tool support have not emerged so far. Therefore, the creation of such systems remains a difficult, time-consuming and error-prone process. The absence of principled support for system evaluation and optimization at high level of abstraction makes the quality of the

This essay reflects on issues surrounding the remembrance and teaching of the Holocaust. It was commissioned by the project Living History and the Swedish Prime Minister's Office.

Popular Abstract in Swedish Under 1990-talet genomfördes en genomgripande reform av det svenska gymnasiet. Dels ersattes de tidigare gymnasielinjerna med treåriga program, som samtliga ger en grundläggande högskolebehörighet, dels flyttades ansvaret för utbildningens genomförande och ekonomi från staten till kommunerna. Ett kriterierelaterat betygssystem ersatte också det tidigare normrelaterade. The general confidence in equal opportunity and equivalent grades are crucial to the moral justification of the social stratification in the modern society, in which meritocracy holds a hegemonic status. In Sweden, a political aim has been that everybody should get upper secondary education, and the government has established a National Agency for Education to promote and control the quality in ed

Based on in-depth interviews with single and married rural women working as temporary migrants in Beijing, this thesis explores motives for migration, as well as consequences of migration on women with regard to social status and their status as dughters, wives and mothers. The thesis concludes that customs regarding marriage and child-bearing in the home villages of the migrants contribute to the

This work provides a game theoretical analysis of the classical idea of a social contract. According to what we might call the Hobbesian justification of the state, coercion is necessary in order to provide people with basic security and to enable them to successfully engage in mutually beneficial cooperation. The establishment and maintenance of a central coercive power, i.e. a state, can therefo
