Förändringar måste vara väl motiverade och förankrade hos både elever och lärare. De måste vara anpassade till skolans mål och den enskilde studentens behov. I denna rapport presenteras ett antal förslag på lösningar till några av de problem som kan uppstå då man försöker införa nya pedagogiska metoder samt motivationens betydelse för det slutgiltiga resultatet.
Most energy behaviour studies on households focus on the questions how and why we use energy and what can be done to lower energy consumption. Very few studies raise the question of when energy is used or examine the underlying explanations to load patterns. Due to economic and technical problems with electricity peak load, it is important to gain knowledge about how the load patterns of household
Popular Abstract in Swedish Enzymer är viktiga ämnen i naturen. Vi talar då och då om att vi förbränner vår mat. Trots detta känner vi oss oftast inte särskilt varma, i alla fall inte så att det bränns. Visst bränner vi vår mat. Socker omvandlas till koldioxid och vatten precis som om vi hade eldat upp det utanför kroppen. Skillnanden är att kroppen omvandlar sockret långsammare och mer kontrollerWith the goal to study the mechanisms of dinuclear metalloenzymes, a new line of synthetic and computational models were prepared and studied. Mixed imidazole and carboxylate multidentate complexes were synthesized to better simulate carboxylate-rich ligand environments. Of the compounds, which showed to be the most useful, were one symmetric and the other one asymmetric and in both cases they wer
Popular Abstract in Swedish Vid njursvikt finns två huvudsakliga metoder för att rena blodet: bukdialys och bloddialys. Vid bukdialys, peritonealdialys (PD), används bukhinnan som dialysmembran, och sockerhaltig dialysvätska fylls på via en kateter i bukväggen. Under dialysen sker transport av slaggprodukter och överskottsvätska från blodet till bukhålan. Dialysen pågår kontinuerligt under hela dyAccording to the three-pore model of peritoneal transport the major exchange pathway between the blood and the peritoneal cavity is represented by “small pores”, permeable to small solutes and water. Osmotically induced fluid flow, as during peritoneal dialysis (PD), is postulated to occur to a great extent through a water-only pathway, whereas proteins are predicted to reach the peritoneal cavity
A theoretical investigation of the stresses in external involute helical gears has been carried out. Geometrical conditions are given and the load distribution along and between the gear teeth in contact is calculated. With this load distribution, contact pressure and fillet tensile and compression stresses are calculated. The influence bending functions, used to calculate the load distribution, a

The development of production methods, research on material engineering and analysis tools for energy conversion processes establish a powerful design environment for any unconventional electromagnetic or electromechanical device. The design for manufacturability becomes the one of the main goals of the design apart from cost and performance improvement. The main focus of this paper lies on the de
This paper establishes reserve price as an ethical necessity contrary to its popular interpretation as an instrument of revenue maximization. It provides an axiomatic justification to reserve pricing at Vickrey auction in single as well as multiple objects settings. In particular, it provides a topological interpretation of a reserve price as the infimum of the set of non-negative real numbers sat
What happens when economies 'heat up'? This book looks at the 1990s, years of intense economic experimentation, when buzz words such as 'network society', 'the experience economy', 'creative cities' and 'glocalization' were everywhere. A fascinating perspective on 'The New Economy' emerges as the authors explore the worlds of coolhunters, biotech brokers, career coaches, software entrepreneurs and
At Lund University an automated video analysis system is being developed that can be applied for studying the behaviour of road users in complex traffic environments. It is stressed that system must be capable of handling all the categories of road users, i.e. vehicles, pedestrians and cyclists. Common problems like detection and tracking of moving objects, occlusion by foreground objects, ground-
