For the classical inviscid water wave problem under the influence of gravity, described by the Euler equation with a free surface over a flat bottom, we construct periodic traveling waves with vorticity. They are symmetric waves whose profiles are monotone between each crest and trough. We use global bifurcation theory to construct a connected set of such solutions. This set contains flat waves as
Objectives: To evaluate the frequency of patellofemoral osteoarthritis and its relevance to symptoms and function in a meniscectomy population. Methods: 317 patients with no cruciate ligament injury were evaluated (mean (SD) age, 54 (11) years). They had undergone meniscal resection 15 to 22 years earlier (follow up rate 70%). Standing tibiofemoral and skyline patellofemoral radiographs were grade
Two two-step fragmentation reactions were performed using RISING to populate excited states in A approximate to 50 mirror nuclei near to the proton-drip line, in order to test isospin symmetry. The experiments were designed to observe gamma decays of excited states in the mirror nuclei Ni-53(28)25/Mn-53(25)28, which have a large value of total isospin (T = 3/2). In the continuing off-line analysis
The synthesis of a nanocomposite material composed of anionic poly(phenylene ethynylene) (aPPE) polymer particles and ZnS/Mn2+ nanoparticles is described, and its luminescence properties are investigated. aPPE particles have two emissions, one in the blue (460 nm) and the other in the green (490 nm), that are assigned to the 0-0 transition and an excimer, respectively. ZnS/Mn2+ nanoparticles have
This integrated study across the Ypresian/Lutetian boundary in the Fortuna Section (Spain) allowed us to recognize a bundle of events in the transitional interval between the Ypresian and Lutetian stages. Planktic foraminifera show an apparently continuous succession spanning the planktic foraminiferal zones P9, P10 and P11. Calcareous nannofossils allowed the recognition of the nannofossil subzon
Heated buildings induce a heat flow from the building foundation into the ground. The topic of this thesis is the thermal process in the ground and, in particular, the heat losses from the building to the ground. Foundations of the three types slab on the ground, cellar, and crawl-space are dealt with. The crawl-space is treated in separate report. A reasonably complete theory for the thermal pro
Popular Abstract in Swedish Avhandlingen handlar om utvecklingsarbete av institutionsvård för ungdomar. Årligen bevil-jar Statens institutionsstyrelse ett tiotal miljoner kronor till utvecklingsprojekt för sina institu-tioner. Sedan i mitten av 1990-talet har stora satsningar gjorts för att utveckla institutionernas kompetens i familj- och nätverksarbete. Syftet med avhandlingen är att undersöka iThe thesis deals with development work within institutional care for young people. The Swedish National Board of Institutional Care (SiS) grants tens of millions of Swedish crowns to development projects to their institutions. Since the mid-1990s major investments have been made in order to develop the institutions? competence in family-work and networking. The aim of this thesis is to study the g
Estrogen and progesterone receptor analysis results were compared within and between six laboratories in Sweden using frozen breast cancer cytosol samples, and the same technique (enzyme immunoassay, Abbott Laboratories). The concordance in receptor status (positive vs. negative) was excellent (98.4% (571/580)). The discordant results were attributable to values near cut-off (n = 4) or outliers (n
Thirty-one children with mediastinal abnormalities--14 malignant lymphomas, 4 other primary malignancies, one metastatic and 12 benign lesions--were examined one or several times using CT, which proved to be effective especially for cysts (5 patients), ductus arteriosus aneurysm (2 patients), and intrathoracic liver (one patient). It also supplied important diagnostic information regarding the ext
An in-car observation method with human observers in the car was studied to establish whether observers could be trained to observe safety variables and register driver's behaviour in a correct and coherent way, and whether the drivers drove in their normal driving style, despite the presence of the observers. The study further discussed the observed variables from a safety perspective. First thre
Popular Abstract in Swedish Tarmväggen har till uppgift att både absorbera vatten och näringsämnen till kroppen, och samtidigt utgöra en barriär mot alla de bakterier, gifter och skadliga ämnen som vi får i oss. Tarmväggen innehåller också kroppens största förråd av immunologisk vävnad, dvs de celler och ämnen som utgörs kroppens försvar. I mag-tarmkanalen, ffa i tjocktarmen, finns 100 biljoner (1The gastrointestinal tract harbours a huge load of bacteria which exerts important biological functions to maintain health. In certain conditions the relation between commensal bacteria and pathogens may be set off balance, with an increase in number of pathogens and risk of bacterial translocation (BT). Disease and trauma may also render the intestinal barrier dysfunctional, inducing BT and incre
Many children with cerebral palsy have feeding difficulties. The aim of this study was to investigate if trunk and neck positioning influenced oral and pharyngeal swallow. Five children with feeding problem aged 3-10 years with cerebral palsy were examined using videofluoroscopy. All children had tetraplegia with dystonia, i.e. poor head control and poor trunk stability. All children had gross asp
In vivo photoactivation of Photosystem II was studied in the FUD39 mutant strain of the green alga Chlamydomonas reinhardtii which lacks the 23 kDa protein subunit involved in water oxidation. Dark grown cells, devoid of oxygen evolution, were illuminated at 0.8 μE m-2&#;s-1 light intensity which promotes optimal activation of oxygen evolution, or at 17 μE m-2&#;s-1, where photoactivation
The throughput performance of incremental redundancy (INR) schemes, based on short constraint length convolutional codes, is evaluated for the block-fading Gaussian collision channel. Results based on simulations and union bound computations are compared to estimates of the achievable throughput performance with random binary and Gaussian coding in the limit of large block lengths, obtained throug
Purpose: We measured concentrations of human glandular kallikrein 2 (hK2), total prostate specific antigen (tPSA), free PSA (fPSA) and percent fPSA to evaluate their relationship to total prostate gland volume, benign prostatic hyperplasia (BPH) volume, total prostate cancer (PCa) volume (CaVol) and the volume of Gleason grades 4/5 cancer (CaVolG14) in the serum of 256 patients with PCa undergoing
Deep-inelastic ep scattering data taken with the H1 detector at HERA and corresponding to an integrated luminosity of 106 pb(-1) are used to study the differential distributions of event shape variables. These include thrust, jet broadening, jet mass and the C-parameter. The four-momentum transfer Q is taken to be the relevant energy scale and ranges between 14 GeV and 200 GeV. The event shape dis
Popular Abstract in Swedish Denna avhandling bygger på en kritisk granskning av spänningen mellan etablerade och alternativa perspektiv på hållbarhetsproblematiken, med utgångspunkt i fyra olika diskurser: miljöekonomi, ekologisk ekonomi, adaptive management och bioregionalism. De fyra diskurserna representerar olika försök att i tilltagande grad utmana etablerade, modernistiska perspektiv på sociThis dissertation critically examines the tension between mainstream and counterpoint perspectives on sustainability on the basis of analyses of four approaches to this issue: environmental economics, ecological economics, adaptive management, and bioregionalism, which are presented as successive attempts to challenge mainstream, modernist perspectives on socio-ecological relationships.
