Laurentius Andreae (Lars Andersson; ca 1470-1552) var 1518-34 ärkediakon i Strängnäs, även i Uppsala. Han blev 1523 kung Gustavs sekreterare och medlem av rådet, avsattes 1531, dömdes 1540 tillsammans med Olaus Petri till döden för majestätsbrott, men benådades. Laurentius ville bygga upp en evangelisk kyrka, medan kungen främst ville överta den katolska kyrkans ekonomiska och politiska makt. Laur
Proton exchange membrane fuel cells (PEMFCs) are expected to play a significant role in the next generation of energy systems and road vehicles for transportation. To achieve high performance, low cost and high reliability, significant attention is needed on detailed modeling and simulation of various physical processes in PEMFC unit-cells. Substantial effort is also required to reach proper water
Although the divergence over the last decades between Europe and USA has drawn much attention, the dispersion of rates of economic growth is even larger among the countries within Europe. There is reason to presume that the more successful among the European countries are those that have set more innovations into production. This paper exploits the correlation between innovation, as materialized i
Aviation is an important driver of individual and global mobility and emissions associated with transports. Recent studies indicate that a relatively small, highly mobile part of society may account for a large share of the total distances travelled. This phenomenon is as yet insufficiently understood. In addressing this situation, the paper reviews the processes leading to growth in mobility, and
This well-written paper is devoted to proving pointwise gradient estimates for functions satisfying a suitable inequality, which arises, for instance, in parabolic obstacle problems as well as in the study of parabolic $Q$-minima.
To increase their computational efficiency, time-stepping methods for the solution of ODEs and DAEs are usually adaptive. A control system for the adaptivity includes the automatic control of step size as well as method order, and can be constructed using proven design principles from control theory. It is a ''superstructure,'' surrounding the basic method, that manages the computational process.
