Background: Impaction grafting in hip revision surgery is widely used but studies with mid- and long-term follow-up are scarce. Patients, methods and results A 5-year radiostereometric (RSA) follow-up of 15 hip revisions with the Exeter stem, morselized impacted allograft bone and cement revealed that 3 stems had not migrated between 2 and 5 years after revision, 11 stems had migrated to a minor

Using the eight-band k center dot p model and the Burt-Foreman envelope function theory to perform self-consistent calculations, we have studied the effect of electron-hole hybridization on the cyclotron masses m(*) and the effective g-factors g(*) of two-dimensional quasiparticles in InAs/GaSb quantum wells under a magnetic field applied perpendicular to the interfaces. We can modify the degree o

Background: Patients needs and experiences attract increasing attention within health care. In order to generate knowledge about the voices that emerge from collaborative experiences between members of patient associations for cancer patients ( PACP) and health care professionals (HCPs), we studied a permanent network aimed at improving cancer care through increased attention to the cancer patient

The interactions between charged alkylacrylamide gels of varying hydrophobicity and charge density and the oppositely charged surfactant hexadecyltrimethylammonium (C(16)TA(+)) have been investigated to determine the conditions necessary to induce excess surfactant binding (beyond charge neutralization) and resolubilization of the polymer-surfactant complex. In all cases, an initial gel collapse o

BACKGROUND: The gold standard to reconstruct a nerve defect is a conventional autologous nerve graft. There may be a lack of such grafts in severe nerve injuries. Alternatives to autologous nerve grafts are needed. METHODS: We have developed a technique where mainly Schwann cells are acutely dissociated from the ends of the severed nerve trunk after nerve injury. The technique does not require lon

We test whether mortality is related to individual income, mean community income, and community income inequality, controlling for initial health status and personal characteristics. The analysis is based on a random sample from the adult Swedish population of more than 40, 000 individuals who were followed up for 10-17 years. We find that mortality decreases significantly as individual income inc

The aim of this thesis was to prospectively evaluate the short-term effect of a non-steroidal anti-inflammatory drug (diclofenac sodium, Voltaren) and stabilisation appliance in controlled trials of patients with temporomandibular disorders (TMD) of arthrogeneous origin. The active treatments were compared to placebo in the study of diclofenac and to a control appliance in the other study. Thirty-

Neutron deficient nuclei close to Sn-100 have been studied using the NORDBALL Ge-detector array together with ancillary particle detectors. Evaporation residues from the compound nucleus Te-108 were identified with charged particle and neutron detectors. In this paper a considerable extension of the level scheme of the nucleus Cd-102 is presented. The strongest cascade of the new level scheme reve

1. The impacts of nutrients (phosphorus and nitrogen) and planktivorous fish on phytoplankton composition and biomass were studied in six shallow, macrophyte-dominated lakes across Europe using mesocosm experiments. 2. Phytoplankton biomass was more influenced by nutrients than by densities of planktivorous fish. Nutrient addition resulted in increased algal biomass at all locations. In some exper

This thesis discusses "social work" as part of missionary work during Hans Egede´s mission in Greenland (1721-1736) and the starting period of the Norwegian Saami mission (1888-1900). The discussion is focused by connecting it to Habermas´s discussion of "The structural transformation of the public" (1989). The discussion includes an analysis of the complexity of contemporary ideas. Missionary wor

Objective: The aim of the present study was to investigate the perceived anxiety, depression, sleeping habits, and participation in social activities in relation to psychotropic drug use among elderly in assisted-living facilities and to identify factors of importance for the use of these drugs. Method: The study had a cross-sectional design and included 93 residents living in old-age homes or in

Male Empress Leilia butterflies (Asterocampa leilia) use a sit-and-wait tactic to locate mates. To see how vision might influence male behavior, we studied the morphology, optics, and receptor physiology of their eyes and found the following. (1) Each eye's visual field is approximately hemispherical with at most a 10degrees overlap in the fields of the eyes. There are no large sexual differences

We present in this work in vitro measurements of the force ejecting DNA from two distinct bacteriophages (T5 and lambda using the osmotic-suppression technique. Our data are analyzed by revisiting the current theories of DNA packaging in spherical capsids. In particular we show that a simplified analytical model based on bending considerations only is able to account quantitatively for the experim
