The dramatic increase in demand for wireless Internet access has lead to the introduction of new wireless architectures and systems including 3G, Wi-Fi and WiMAX. 3G systems such as UMTS and CDMA2000 are leaning towards an all-IP architecture for transporting IP multimedia services, mainly due to its scalability and promising capability of inter-working heterogeneous wireless access networks. Duri

Water column (dissolved/suspended phase, sediment traps) and sediment data (pore-water, solid-phase sediment) were combined with stable Pb and Pb-210 isotope data to trace the early diagenetic behaviour and geochemical cycling of Pb in Lake Laisan, a lake which has received large quantities of anthropogenic Pb since the early 1940s. Early diagenetic remobilisation of Pb is indicated by a subsurfac

Macroscopic phase separation in covalent sodium polyacrylate (PA) networks following the absorption of cetyltrimethylammonium bromide/chloride (CTAB/C) from aqueous solutions is studied experimentally and theoretically. The gels are shown to consist of a solvent-swollen polyelectrolyte network (core), surrounded by a dense surface phase (skin) of polyion/surfactant complexes. The effect of core sw

Background Few authors have investigated function and pain after surgical treatment of patients with bone metastases. In 1999 the Scandinavian Sarcoma Group (SSG) initiated the Skeletal Metastasis Registry as a multi-centric, prospective study to provide a scientific basis for recommendations of treatment. Patients and methods We have analyzed function and pain in 530 patients (mean age 65 yr) ope

In this thesis, the developments of two different low-cost scanners for positron emission tomography (PET) based on 3D acquisition, are presented. 3D reconstruction methods for these systems are also presented. The first scanner consists of two rotating scintillation cameras, and produces quantitative images, which have shown to be clinically useful . The second one is a system with two opposed se

Cloud retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments aboard the satellites Terra and Aqua and the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard the Suomi-NPP satellite are evaluated using a combination of ground-based instruments providing vertical profiles of clouds. The ground-based measurements are obtained from the Atmospheric Radiat

Given its emphasis on understanding marketing systems through their reciprocal interactions with society, the task of developing a methodology that captures such complexity is particularly crucial for macromarketing. The aim of the present contribution is to elaborate a methodological approach that is able to operationalize macromarketing complexity into more comprehensive and analyzable forms, wh

The essay, The New Clothes of Death is about the funeral customs in Sweden from a culture-historical perspective with an ethnological touch. The essay deals with our present day relation to death and how this can be transformed to the dead person. The questions are highlighted with observations from two funerals, one cremation and, studies of the cemetery environment and the culture of the graves.

The thesis presents fairness as a concept that can be defined in several ways. The different definitions overlap and influence each other in a somewhat unexpected manner. The conclusion of this thesis is that the utilitarian approach first presented as a philosophical theory of fairness by Jeremy Bentham is so far clearly seen as the overriding basis for the CJEU judgements. However, the adopted A

This master thesis project has been performed in cooperation with AGA, the well-known gas company which is a part of the German Linde group and the Department of Automatic Control, Lund Institute of Technology. Since summer 2000 AGA has developed and manufactured a fully automated reactor producing bicarbonate solution for stabilizing pH in papermaking processes. The reactor or ACU!22 (alkalinity

Lunds kommun utforskar möjligheter för ett digitaliserat samhälle och därför bestod detta arbete av en behovskartläggning inom kommunens LSS-verksamhet unIkT. Kartläggningen involverade personer med autismspektrumtillstånd där deras väsentliga behov som saknade stöd, skulle tillfredsställas med hjälp av en digital lösning. Datainsamlingen inkluderade bland annat intervjuer och brainstorming med uThe municipality of Lund is in the process of exploring opportunities for a digital society. This work consisted of a need’s assessment within the municipality’s inclusive community setting unIkT. The mapping involved individuals with autism spectrum disorder, and how their essential needs could be satisfied with the help of a digital solution. The data gathering included interviews and brainstor

The topic of this study is to develop and validate an analysis method of nicotine nasal spray produced at McNeil AB. When developing the analysis method, several parameters were determined in advance to make the method more similar to other analysis methods at the company, making it more practical. However, other parameters were adjusted with the aim to improve the resolution and to fulfil the upd

The thesis explores the possibilities of the Swedish government to assure effective waste collection policies for mercury-containing gas-discharge lamps (GDL) in the context of phase-out of incandescent light bulbs. The study includes review of the waste collection, the waste collection evaluation, policy review and policy analysis. The specific analytical tools applied include Lindhqvist’s policy

Hyaluronan is an unsulfated linear glycosaminoglycan with the ability to nucleate extracellular matrices by the formation of aggregates with lecticans. These matrices are essential during development of the central nervous system. In the prospective white matter of the developing brain hyaluronan is organized into fiber-like structures according to confocal microscopy of fixed slices which may gui
