Popular Abstract in Swedish Äldre människor har ofta många hälsoproblem som t.ex. svårigheter att gå, se, höra, smärta och inkontinens men hur vanligt det är bland de allra äldsta är lite under¬sökt. De olika hälsoproblemen kan finnas samtidigt och i särskilda mönster men få studier har gjorts om detta. När ett hälsoproblem läggs till ett annat kommer det kanske till en punkt när behov av hjälp ärAim: The aim of this thesis was to investigate type, degree and patterns of health complaints, need for help and health-related quality of life across gender among persons aged 75?105 as well as to identify how patterns of health complaints, gender, age and socio-economic factors related to need for help with daily activities and quality of life (Paper I). The aim was also to investigate the preva

1. We experimentally tested if a multiplicative risk model accurately predicted the consumption of a common mayfly at risk of predation from three predator species in New Zealand streams. Deviations between model predictions and experimental observations were interpreted as indicators of ecologically important interactions between predators. 2. The predators included a drift-feeding fish [brown t

BACKGROUND: Intestinal inactivity leads to atrophic changes and concomitant alterations in the expression of neurotransmitters in the enteric nervous system. In atrophic rat ileum neurones expressing vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating peptide (PACAP) decrease in number while nitric oxide synthase (NOS) expressing neurones increase. Since little is known

The present study addresses the question why there is a positive relationship between nitrogen deposition and potential net nitrogen mineralisation and nitrification in oak (Quercus robur L.) forest soils in south Sweden (Falkengren-Grerup et al., 1998), and how this is related to the carbon mineralisation. We tested three hypotheses based on European studies (Persson et al., 2000a,b) that postula

High spin states in the neutron deficient isotopes Ru90 and Ru91 have been studied in the 2p2n and 2pn exit channels of the reaction Ar-36 + Ni-58 using the 149 MeV Ar-36 beam at VICKSI and the OSIRIS array. By gating the gammagamma coincidences with evaporated neutrons and protons, excited states in Ru90 were identified for the first time and the level scheme of Ru-91 was extended. In both nuclei

Popular Abstract in Swedish Bakgrund För att diagnostisera förändringar i käkbenet är röntgenundersökning av stor betydelse. En bendestruktion blir synlig i röntgenbilden först när relativt stor mängd ben försvunnit. Flera tidigare studier har visat att destruktionen inte ses förrän den påverkar den kompakta yttre delen av käkbenet. Andra studier har däremot visat att destruktionen kan ses tidigaThe aim was to study digital radiography and to evaluate the influence of image processing on digital dental radiographs for the assessment of periapical lesions. In four studies, artificial bone lesions were made periapically and interradicularly in the mandibular premolar and molar regions. In a clinical study, direct digital radiographic images depicting the periapical bone tissue of different

Forerunners (precursors) in linear, temporally dispersive, bigyrotropic materials are investigated with time-domain techniques. Bigyrotropic materials are characterized by 12 constitutive parameters (integral kernels). Specifically, the four susceptibility dyadics are all gyrotropic with a common gyrotropic axis. Pulse propagation along this axis is analyzed with dispersive (noncoupling) wave spli

Late Precambrian and Palaeozoic platform sediments from the Central-South Taimyr Peninsula (Arctic Siberia) are all remagnetised. The remagnetisation is prefold and is related to thermal remagnetisation caused by Taimyr Trap magmatism. The remagnetisation age is estimated to 220-230 Ma and, hence, is considerably younger than the ca. 251 Ma age for the main body of Siberian Trap flood basalts. The

Intervju med Lars von Trier under inspelningen av filmen Europa.

The first Scandinavian case of Aeromonas veronii biovar sobria infection, an episode of peritonitis in a patient suffering from a cirrhotic liver and an earlier unrecognized appendiceal cancer, is described.
