Popular Abstract in Swedish Döva barns begreppsbildning i matematik Denna studie tar utgångspunkt i frågan varför många döva barn har svårt att lära sig matematik. Studiens syfte är att belysa döva barns begreppsbildning i ämnet matematik genom att beskriva hur några döva barn uttrycker sig och agerar på väg mot förståelse av två centrala matematiska begrepp, nämligen multiplikation med heltal ochThe question why deaf children have difficulties in learning mathematics is the basis of this study. The aim of the study is to illuminate deaf children’s concept formation in mathematics by describing how some deaf children express themselves and act on their way towards understanding two basic concepts, the concept of multiplication with whole numbers and the concept of length. Theories develope

Johannes of Rheinfelden’s treatise on card-playing, the Ludus cartularum moralisatus (“the moral meaning of card-playing”) is not only an important source of the history of plays and pastimes but also gives valuable information about late medieval thinking concerning the organization of human society. Johannes writes that the newly introduced cards were something of a revelation for him and that h

The thesis deals with determination of the post peak behaviour of wood in pure tension and pure shear. Furhermore, the "Fictitious Crack Model" (FCM), which is a nonlinear fracture mechanics model ; originally developed for description of crack propagation in concrete, is employed to demonstrate the advantages of non linear fracture mechanics. A testing arrangement is presented with which the comp

The article comprises the second part (Nostocales) of our study of little known planktic and metaphytic cyanoprokaryotes (cyanophytes, cyanobacteria) from ponds, lakes and water reservoirs in East and Southern Africa. The morphology and variation of 17 species was studied, and comments about their ecology and taxonomy are included. Seven new species are defined: Anabaena austro-africana, A. carmic

Osteoadherin (OSAD) is a keratan sulfate proteoglycan recently isolated from bovine and rat bone. Based on results obtained from in vitro experiments, the protein was shown to bind osteoblasts via the integrin receptor alpha(v)beta(3). Due to OSAD's capacity to bind hydroxyapatite crystals, a role for the protein in the mineralization process has also been suggested. To test these hypotheses in an

Views and proposals on housing improvement and social participation in Latin America have gone through changes in the last decades. These changes are noteworthy. In general, the population living in settlements scheduled to be upgraded, and the people target for participatory action, did not have much say in policy making. Housing improvement and social participation issues are linked to the Law o

This dissertation deals with analog techniques at both the architecture and circuit design levels for designing power efficient linear radio-frequency (RF) transmitters. The use of nonlinear analog integrated circuits to implement certain critical signal processing functions for the multiplicative feedback and LINC techniques is investigated with the aim of improving the system performance in term

During most of the 20th century shelters for the homeless has been criticized as being of too low standard and an unworthy way of living in a welfare society. During the 1960s and 1970s most shelters in Sweden were shut down and replaced with other forms of housing for the homeless. Since the late 1980s and early 1990s the issue of homelessness has returned to the political agenda as an existing s

Popular Abstract in Swedish Denna avhandling innehåller en huvudstudie och en delstudie. Syftet med huvudstudien var att följa upp en grupp ungdomar som hade blivit diagnostiserade med uppförandestörning (n=351) i det unga vuxenlivet. Delstudiens syfte var att ifrågasätta och klargöra frågeformuläret KASAM-29 och dess förhållande till den salutogena teorin. I avhandlingen användes olika utfallsvarThis dissertation consists of a primary and a secondary study. The aim of the primary study is to follow-up a group of juveniles diagnosed with conduct disorder (n=351) into adulthood. The secondary study's aim is to question, clarify and attach the questionnaire SOC-29 to the salutogenic theory.In the dissertation different outcomes and outcome measurements are fomulated and discussed. Two perspe

In rats the flow of urine was diverted from the bladder over a period of 7-10 days. Active length-tension curves of muscle strips of such disused bladders did not differ from those of controls, provided lengths were related to optimum length for force development. When, however, lengths were related to length in situ the active length-tension curves were shifted to the left. The muscle strips of t

In order to deliver innovative and cost-effective IP multimedia applications over mobile devices, there is a need to develop a unified service platform for the future mobile Internet referred as the Next Generation (NG) all-IP network. It is convincingly demonstrated by numerous recent studies that modern multimedia network traffic exhibits long-range dependence (LRD) and self-similarity. These ch

Popular Abstract in Swedish Denna avhandling handlar om experimentella tekniker och dataanalys inom atomspektroskopi. Förbättrade metoder för analys av spektra och bestämning av nivåenergier presenteras, där de flesta bygger på en rigorös statistisk behandling av spektroskopisk data. Starka linjer i spektrumet från envärt joniserat neon mellan 2000 och 5000Å föreslås som våglängdsstandarder. DessaThe focus of this work is on the experimental techniques and data analysis in atomic spectroscopy. Improved methods for the analysis of spectra and the determination of level energies are presented. Most of these are based on a rigorous statistical treatment of the spectroscopic data. Strong lines in the spectrum of singly-ionized neon between 2000 and 5000Å are suggested as tertiary wavelength st

This paper presents the findings from a design study of a model-based framework for safety-critical software development, called SimPal. The objective of the study was to better understand the necessary properties of such a framework and to learn more about the challenges of realizing it. Our research approach can be labeled as design research, which means that we try to answer our research questi

Popular Abstract in Swedish Hur tillgängligt är EU för asylsökande? Står Unionens rättsregler i strid med folkrätten? Om så är fallet, hur löser vi konflikten dem emellan? Besitter vi alls medel för att lösa grundläggande konflikter om hur långt rätten skall skydda "utomstående"? Denna avhandling söker svar på frågorna genom att kombinera formaljuridik med statsvetenskapliga förklaringsmodeller. MHow are access to asylum and other forms of extraterritorial protection regulated in the European Union? Is the EU acquis in these areas in conformity with international law? What tools does international law offer to solve conflicts between them? And, finally, is law capable of bridging the foundational oppositions embedded in migration and asylum issues? This work combines the potential of legal
