A straightforward gradient expansion of the exchange energy of a perturbed electron gas is performed. Studied perturbations range from very weak to those that produce, e.g., a silicon-like band structure with a band gap. The expansions involve density gradients up to fourth degree and we include all terms originating in linear- and second-order response theory. The expansion reproduces exactly cal

This paper deals with policy measures in the regional innovation system of Scania, Southern Sweden. Focus is dedicated to requirements on innovation policy from actors representing different industries. Previous studies have identified profound differences with regard the organization of knowledge sourcing between firms and other actors in industries drawing on different knowledge bases. In corres

This thesis discusses the feasibility of a low emittance lattice proposed for the MAX-IV storage rings. The MAX-IV facility will have two storage rings that are identical but operated at two different energies, 1.5 GeV for soft X-ray and 3 GeV for hard X-ray production. The lattice is built to take advantage of the small gap insertion devices that imply small apertures in the magnet elements whic

Popular Abstract in Swedish På 70-talet upptäckte man att en grupp mikroorganismer, som man tidigare katalogiserat som bakterier, bildade en helt egen grupp. Dessa kallades ärkebakterier och fick senare namnet arkéer. Arkéer är små (ca 1 tusendels millimeter) encelliga organismer precis som bakterier, men de skiljer sig på många sätt från dem. Till exempel har de en kemiskt annorlunda uppbyggd celDuring the last decade it has been discovered that around 2% of the soil-living prokaryotes belong to the domain Archaea. In many soils the most abundant archaeal group is the ammonia-oxidizing archaea (AOA) that, in addition to ammonia-oxidizing bacteria (AOB), preform the first and rate-limiting step in the nitrification process. The knowledge of factors that regulates the archaeal abundance and

Popular Abstract in Swedish Helicobacter pylori är en bakterie som orsakar såväl magkatarr, magsår som magsäckscancer. H. pylori producerar olika virulensfaktorer såsom enzymet ureas, ett cell vakuolbildande toxin (VacA), andra cytotoxiska proteiner (cagA eller pathogenicity island-associated proteins), flageller och adhesiner. För etablering av H. pylori infektion, måste dessa virulensfaktorer inHelicobacter pylori is a gastric pathogen which cause chronic type B gastritis and peptic ulcer disease. H. pylori produces virulence factors such as urease, vacuolating cytotoxin VacA, cag pathogenicity island-associated proteins, flagella and adhesins. These proteins interact with several host cell molecules such as sialylated cell surface glycoproteins, some of glycolipids and mucins. Glycosami

A reduced-order through-flow program has been developed at the Lund Institute of Technology. The goal of the work was to develop and verify a program suitable for scientific studies of coaxial turbines. The program has built-in capability for multiple choked stages, and turbine cooling, as well as flexible modules for state, losses, deviation, and blockage. The code uses Matlab [trademark] as a pl

A previously developed computational model for 3D finite element simulations of wood during moisture changes is in the present work provided with a special-purpose graphical user interface. The software is designed to use a personal computer for the graphical user interface and to have possibility to use distributed computational resources for the simulation.

Study of the representation of Mark Antony in the HBO televison series Rome. Here, Mark Antony is represented in all his traditional guises as a soldier, a politician, a womanizer, a drunkard and finally as he develops into a transsexual appearance in his subjugated relationship to Queen Cleopatra of Egypt.
