Recycling of building waste can considerably reduce the need for energy and natural resources and reduce the amount of material to landfill. Knowledge of the size of the annual conservation potential is important. The purpose of this study was to assess the conservation of energy and natural resources and the amount of material to landfill by recycling building waste in Sweden. Two recycling scena

A numerical model of beach topography evolution due to waves and currents in the vicinity of coastal structures was developed. The model consists of five sub-models for nearshore random wave transformation, surface roller development, wave-induced currents, sediment transport, and morphological evolution. It was validated based on high-quality data sets from the Large-scale Sediment Transport Faci

Popular Abstract in Swedish I allt större grad har effektivitetsbegreppet kommit i fokus i samhällsomvandlingen. I huvudsak utgår vi från att effektivitet i första hand är liktydigt med ekonomisk effektivitet. Existensen av en slags övergripande, ekonomisk "rationalitet", tas för given och har närmast karaktären av naturlag eller central, samhällelig grundbult. Under det senaste decenniet har omfaThe study takes as its starting point the far-reaching organizational changes that have occurred within the public sector in Sweden, particularly the public health care sector, during the last decade. The aim of achieving efficacy has been an important driving force in these processes, which often concern mergers or reductions in personnel that are regarded as a route to success. Paradoxically, Sw

Popular Abstract in Swedish Ett varmare klimat ökar generellt risken för angrepp av skadeinsekter på jordbruksgrödor, och många skadeinsekter förväntas sprida sig norrut. Den här avhandlingen fokuserar på hur ett varmare klimat kan påverka koloradoskalbaggen, en allvarlig skadegörare i potatisodlingar. Koloradoskalbaggen kom från Mexiko till Europa i början av 1900-talet, och har sedan dess spridiEuropean agriculture is facing the challenge of managing the impact of climate change on food security. Agriculture in a northern temperate climate is likely to benefit from higher temperature and longer growing season while, in the south, crop productivity is likely to decline. Such changes in climate could also affect the population dynamics of insect pests. The Colorado potato beetle (CPB) is o

Popular Abstract in Swedish Patienten med underbensamputation på grund av kärlsjukdom Långt före Kristi födelse var amputation av benet en känd operation. Anledningen till amputationen kunde vara kärlsjukdom, olycksfall, tumör eller medfödda missbildningar. I västvärlden idag utförs 90 % av amputationerna på grund av kärlsjukdom. Dessa patienter är äldre och sjukare än övriga benamputerade och meThe patient with unilateral trans-tribal amputation for vascular disease. Functional assessments, prognostic factors and cost of prostheses. The aims of the study were to focus on the functional ability of the dysvascular patient with unilateral trans-tibial amputation and the early rehabilitation period, defined here as the period between the amputation and the prosthetic fitting.

Traffic measurements in broadband access networks are crucial from several points of view. A better understanding of traffic patterns can lead to more efficient network design, which leads to energy and cost savings for the operator and improved end user services. This paper reports on selected traffic measurement results from the Celtic TRAMMS project. The measurements were performed in broadband

Popular Abstract in Swedish De befintliga terapier som finns att tillgå mot hjärntumörer, t. ex strålning, kemoterapi och kirurgi, har varit utan framgång och få patienter lever längre än två år efter diagnostisering. Vi har försökt att etablera en ny terapi mot hjärntumör, som använder kroppens eget immunsystem för att lokalisera och avdöda tumörceller. Kroppens immunsystem innehåller olika celltImmunotherapy is a new promising approach in cancer treatment. In the future, it will hopefully offer an alternative to existing brain tumors treatments, which are unable to cure. We have established an experimental, low immunogenic, brain tumor model in the rat. We have increased tumor cell immunogenicity with mutagen treatment or transfection of IFN-g. Mutagen treated glioma cells (tum-) could c
