Internationell handel - även för jorbdruket?

Sedan 50 år har multilaterala förhandlingar lett till att det blivit lättare att mellan länder handla med industrivaror. Detta har lyckats genom en insikt hos deltagande länder att de gemensamt har att vinna på att förbättra handelsmöjligheterna. Trots denna insikt har gjorda överenskommelser inte omfattat handeln med jordbruksprodukter, förrän i den allra senaste förhandlingsrundan. Är det svårar

Mortars for Masonry and Rendering Choice and Application

Choosing the right mortar for the job, and applying it correctly, gives a strong structure requiring less maintenance. A common problem is using too much cement in the mix, which is unnecessarily expensive and has technical disadvantages. Another common problem is using too thick a layer of rendering, which increases the risk of flaking and cracking. A masonry wall must meet several requirements

Modelling of plasticity and damage in a polycrystalline microstructure

The mesomechanical behavior of a polycrystalline microstructure subjected to monotonic and cyclic loadings is investigated. The analysis is based on a Voronoi polygonization strategy for generation of grains embedded in a contiguous matrix. The main emphasis is to investigate the interaction between the microconstituents and the failure processes along grain boundaries. A rational interface theory

Antenna Bandwidth Optimization with Single Frequency Simulation

A method to compute antenna Q using an electromagnetic simulation at a single frequency is described. This method can easily be integrated into global optimization algorithms. In this way the optimization time of some antenna parameters, e.g., bandwidth, may be significantly reduced. The method is validated by direct comparison with the physical bound of the analyzed structure. Numerical examples
