We report a theoretical study of the electronic structure and optical properties of GaAs nanowires grown in the [111] direction with a hexagonal cross section, based on a tight-binding approach. It is shown that in the nanowires the degeneracy of the light-hole and heavy-hole bands at the Γ-point seen in the bulk material is lifted, and the light-hole state is located above the heavy-hole state, i

”IT-baserad-Rumänska”-konceptet har visat sig vara en mycket bra utbildningsmodell bl a för att öka studentantalet. Vi presenterar vår e-lösning för att ”snappa upp” ”rest*-studenter” och därmed höja genomströmningen – ett moment som visar sig vara omöjlig inom campusmodellen. Vi presenterar våra resultat i en statistisk överblick. (*Studenter som har rest-prov.)

Tracing secondary rays, such as reflection, refraction and shadow rays, can often be the most costly step in a modern real-time ray tracer. In this paper, we examine this problem by using suitable ray coherence measures and present a thorough evaluation of different reordering heuristics for secondary rays. We also present a simple system design for more coherent scene traversal by caching seconda

Derived from the renowned multi-volume International Encyclopaedia of Laws, this practical analysis of the law of contracts in Sweden covers every aspect of the subject – definition and classification of contracts, contractual liability, relation to the law of property, good faith, burden of proof, defects, penalty clauses, arbitration clauses, remedies in case of non-performance, damages, power o

This thesis presents the study of the phase behavior of starch ? protein systems in relation to their microstructure and mechanical properties. To study the complexity of this multicomponent system, the main components of starch (amylopectin and amylose) were studied separately in presence of a protein (ß-lactoglobulin or patatin). The two-component systems in aqueous media or dry state were: amy

Att den kunskap som produceras innanför laboratoriet inte utan vidare kan överföras till omvärlden, att det snarare uppstår en rad informationsglapp, problematiseras i artikeln. Lundin utgår från samtalen i en diskussionsgrupp med biomedicinska forskare där avsikten är att resonera om medicin och etik. Gruppen utgör en metodologisk ingång för att fånga vad som händer i gränslandet mellan enskilda

Much like the way we distinguish between formalism and experimentalism, we distinguish between ascertainment by proof and ascertainment by measurement. We argue that quantum mechanics, which characteristically encompasses both kinds of ascertainment, is too complex to be fully captured by formalism alone, and needs relativization to language in its complementaristic conception. In particular, we a

Popular Abstract in SwedishI denna licentiatavhandling undersöks för det första de redskap för atthantera historia som samhället vill att eleverna skall tillgodogöra sig. För det andra kastar den ljus över i vilken utsträckning eleverna ges möjlighet att tillgodogöra sig dessa redskap. I undersökningen jämförs lärares skriftliga instruktioner för insamlande av bedömningsunderlag, till exempel provIn this licentiate thesis is the focus is on what tools for handling historical information that is mentioned in the standards for history education in the Swedish upper-secondary school. To what extent these tools are made available for the students by their teachers is also investigated. That is done, by looking at teachers assessment materials. The results show a very low degree of alignment be
