Popular Abstract in Swedish Information om smärta, klåda och temperaturförändringar förmedlas till centrala nervsystemet av tunna nervfibrer som leder nervimpulser relativt långsamt. Information om beröring av huden förmedlas istället av grova och snabbt ledande nervfibrer. Det är välkänt att olika känselkvaliteter kan interagera med varandra på olika nivåer i centrala nervsystemet. Vanlig berörinIt is known that stimulation of thin nerve afferents can inhibit itch and pain and that the nociceptive systems have a detailed topographical organisation, with subsystems exhibiting specific excitatory and inhibitory receptive fields. On this basis, a new technique was developed, termed Cutaneous Field Stimulation (CFS), that electrically stimulates thin nerve fibers innervating specific skin fie

Drawing on a combination of empirical industry observations and management literature, this document at- tempts to shed some light on the usage of the term ‘convergence’ that can be identified within the security sector. The aim is to provide both a typology of definitions and a discussion of some of the strategic implica- tions of different types of convergence. A basic distinction is made betwee

Mycorrhizal symbioses are formed between plant root systems and compatible fungal hyphae that results in a complex mixed structure. They are found in all ecosystems and with the majority of land plants such as forest trees or crops that are of commercial interest. Mutual exchange of nutrients between the two symbionts is central to the successful functioning of the symbioses. In order to understan

Popular Abstract in Swedish Strålningsterapi är en viktig metod för att behandla många cancertyper och man söker konstant efter olika sätt att förbättra användningen av joniserande strålning vid behandling. Radiobiologisk forskning för cancerterapi söker att förbättra vår förståelse för hur joniserande strålning verkar på olika livsformer. Idag finns det många sätt att utröna en behandlings inverkFor the development of a Single–Ion Hit Facility (SIHF) for living cells irradiation at the Lund Ion Beam Analysis facility (LIBAF), newly developed pre-cell detectors have been investigated. These detectors can determine the number of ions reaching the sample. Central to the thesis is their fabrication and characterization. Two different detectors ’ Design A and Design B’ were fabricated with thi

If engineering designers consciously design product and package in an integrated manner, there is a great potential for industrial global enterprises to develop and produce mechanical products, such as exhaust extraction systems, ear washer machines and fuel handling systems while simultaneously obtaining error-free deliveries, saving costs and avoiding quality problems. Thus, the authors of this

This study uses the Swedish register of prescribed drugs, merged with the Survey of Living Conditions (the ULF), to analyze the socioeconomic gradient in drug utilization. It finds a significant education gradient (but no income gradient) in individual drug utilization. Whereas the education gradient for men is quantitative in its orientation (education affects number of drugs used), the gradient

Popular Abstract in Swedish Inom växtriket finns det ca 3000 arter som är parasitiska och dessa växer i nästan alla större ekosystem på land. Parasitiska växter kan delas in på olika sätt, helparasiter respektive halvparasiter. Denna indelning baserar sig på om de saknar klorofyll och tar all sin näring från sin värdväxt (helparasiter) eller har klorofyll och kan själva framställa kolhydrater men Parasitic plants are found in nearly every major terrestrial ecosystem and can be divided into two groups, holoparasites (lacking chlorophyll) and hemiparasites (chlorophyllous). The host-parasite connection is either situated above (stem parasites) or below ground (root parasites). In this thesis I examine the host-parasite interactions, host range and selection, and population dynamics of four r

The stereotypes about older adults and the incomplete picture that emerges when such persons are described in terms of properties and a characteristic derived from ageing is one motivation for defining the status of older users. The other key motivation is that the elderly are just one user-group among others so that the perspective on how technology is used may or may not tell us something about

Popular Abstract in Swedish Har alkohol någon skadlig effekt på människoskelettet? Vid Avdelningen för ortopedi på Universitetssjukhuset MAS har vi studerat detta problem och min avhandling är ett försök att besvara frågan. Siffrorna över konsumtionsmönstret för alkohol är osäkra - i Malmö är minst 9% av den manliga befolkningen högkonsumenter. Enligt nyligen publicerade data dricker män mest i åThe influence of alcohol on bone metabolism, fracture and fracture healing was evaluated in men and male rats by measurements of bone mineral density (BMD), biochemical markers and biomechanical testings. Retrospectively, 199 male patients hospitalized for tibia shaft fractures were studied. Forty-nine were judged as problem drinkers. Abusers were more prone to sustain oblique fractures. The heal

Starch and cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution and properties is important in order to design modification processes so as to produce derivatives with the desired properties. This thesis describes research on analytical methods for the determination of the distri

Most recent publications on spin-related phenomena focus on technological aspects of spin-dependent transport, with emphasis on the specific needs of spintronics. The present publication targets rather fundamental problems related to the physics of spin in solids, such as: manifestation of spin and orbital polarization in spectroscopy, including valence and X-ray photoemission, magneto-optics, low

Syftet med detta projekt var att studera samspelet mellan friktion, balansförmåga och halkrisker, samt att ta fram designrekommendationer för friktionskrav och halksäkrare skor och underlag. Sex studier har utförts innefattande friktionsmätningar av skor på olika underlag och temperaturer, studier av stående balans och gång på ramp med justerbar lutning samt fokusgruppintervjuer. Resultaten visar

The uptake of nutrients from deep soil layers has been shown to be important for the long-term nutrient sustainability of forest soils. When modelling nutrient uptake in forest ecosystems, the nutrient uptake capacity of trees is usually defined by the root distribution. However, this leads to the assumption that roots at different soil depths have the same capacity to take up nutrients. To invest
