Popular Abstract in Swedish Vatten- och läskflaskor av polyetylentereftalat, PET, kan både återanvändas (återfyllbara flaskor) och/eller återvinnas. Vid återvinning kan materialet användas för tillverkning av nya flaskor, sk closed-loop recycling. I både återfyllbara flaskor och flaskor som innehåller återvunnet material kan det förekomma ämnen som tidigare trängt in i plasten. Dessa kan antingen The reuse and closed-loop recycling of food packaging was studied in order to assess consumer safety and the sensory quality (e.g. taste and smell) of packaged food. Polyethylene terephthalate (PET) beverage bottles that were refillable or that contained recycled material, either in direct contact or with a functional barrier protecting the food, were investigated with focus on odorous compounds f

”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

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

Within cognitive science, two approaches currently dominate the problem of modeling representations. The symbolic approach views cognition as computation involving symbolic manipulation. Connectionism, a special case of associationism, models associations using artificial neuron networks. Peter Gardenfors offers his theory of conceptual representations as a bridge between the symbolic and connecti

This book develops “Macroeconomic Uncertainty Strategy” (MUST) as a tool for coping with the impact of macroeconomic fluctuations on risk management, performance assessment, and strategies for value enhancement. The essential elements of a corporate strategy for managing uncertainty in the macroeconomic environment includes setting corporate objectives for risk management, measuring risk, choosing

The finite element method has been used to analyse three topologies of iron-powder electrically magnetized synchronous machines. The first topology has the field winding placed in magnetically conducting end-plates, eliminating the need of slip-rings. In the second topology this is achieved by placing the winding above the outer rotor, and the third topology corresponds to the more conventional de

Animals can detect different parameters of the geomagnetic field by two principal independent magnetoreception mechanisms: (1) a light-dependent process detecting the axial course and the inclination angle of the geomagnetic field lines, providing the animals with magnetic compass information (inclination compass), and (2) a magnetite-mediated process, providing magnetic map information (map sense

Kort presentation av bibliotekarieutbildningen i Lund och dess speciella profil.

Popular Abstract in Swedish Denna skrift behandlar marklagring av värme, kyla och kärnavfall.The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. All these storage systems induce multidimensional, time-variable thermo-hydr
