1976 through 1992, 30,003 primary knee arthroplasties and their revisions have been recorded in a nation-wide Swedish study. We report on the structure of the register, demographic data and survivorship. We found that operations for osteoarthrosis (OA) counted for the increase in number of arthroplasties in contrast to rheumatoid arthritis (RA), where the number had slightly declined. For primary
To study the carrier frequency effects on path loss, measurements have been conducted at four discrete frequencies in the range 460-5100 MHz. The transmitter was placed on the roof of a 36 meters tall building and the receive antennas were placed on the roof of a van. Both urban and suburban areas were included in the measurement campaign. The results show that there is a frequency dependency, in
Sole carbon source utilization (SCSU) patterns and phospholipid fatty acid (PLFA) profiles were compared with respect to their potential to characterize root-inhabiting microbial communities of hydroponically grown crops. Sweet pepper (Capsicum annum cv. Evident), lettuce (Lactuca sativa cv. Grand Rapids), and four different cultivars of tomato (Lycopersicon esculentum cvs. Gitana, Armada, Aromata
Popular Abstract in Swedish Hållbar utveckling är ett ofta använt begrepp, som många inte riktigt förstår eftersom det går på tvärs mot traditionella vetenskapliga begrepp som förutsägelse och styrning. Många vetenskapsmän har tolkat begreppet på sätt som gynnar den egna agendan. Dessa vantolkningar har lett till att begreppet inte kommit till användning i praktisk planering. Avhandlingen hävdar As Sustainable development, a widely used but poorly understood term, challenges traditional scientific values such as prediction and control, scientists have tried to manipulate the concept to promote their own particular agendas. Thus, it has suffered from misrepresentation which has prevented the concept from being fully implemented at a practical level. It is asserted that traditional fragmen
A 6-cylinder truck engine is modified for turbocharged dual-fuel Homogeneous Charge Compression Ignition (HCCI) engine operation. Two different fuels, ethanol and n-heptane, are used to control the ignition timing. The objective of this study is to demonstrate high load operation of a full-size HCCI engine and to discuss some of the typical constraints associated with HCCI operation. This study pr

Two efficient Monte Carlo models are described, facilitating predictions of complete time-resolved fluorescence spectra from a light-scattering and light-absorbing medium. These are compared with a third, conventional fluorescence Monte Carlo model in terms of accuracy, signal-to-noise statistics, and simulation time. The improved computation efficiency is achieved by means of a convolution techni
Popular Abstract in Swedish We address the problem of the dissipative character of collective motion in finite Fermi systems. We study this problem from the point of view of chaotic features of the fermionic degrees of freedom of the many-body Fermi systems. Our main aim is of two kinds: first, we investigate how quantum chaos sets in in many-body systems and then, we try to relate quantum many-boWe address the problem of the dissipative character of collective motion in finite Fermi systems.

Popular Abstract in Swedish Personer, särskilt äldre, som vårdas på sjukhus kan under vårdtiden utveckla ett tillfälligt förvirringstillstånd (akut konfusion, ACS). Tillståndet är ofta förenat med obehag för patienten och efteråt ber de ibland vårdarna om ursäkt för sitt beteende. Det är därför angeläget att vårdarna har en uppfattning om hur de skall förhålla sig till patientens förvirrade beteenThe aims of this thesis were to investigate factors of significance for the development of acute confusional state (ACS), the confusional episodes, the lived experiences of having been confused in elderly patients admitted for emergency or elective surgery in orthopaedic care. A further aim was to investigate the nurses’ view of the ACS and the encounter with patients who developed ACS. A case stu
Popular Abstract in Swedish I denna avhandling studeras förändringar i individers religiositet i samband med migration och vad som orsakar sådana förändringar. Det huvudsakliga materialet för studien består av intervjuer med sverige-chilenare boende i Malmö-Lundområdet, vilka berättat om vad som skett med deras religiositet efter ankomsten till Sverige. I arbetet ingår även en brevenkät till sveriThe purpose of this study is to examine changes related to migration in the religiosity of individuals and what lies behind such changes. The study is foremost based on interviews with 23 Swedish-Chileans who have lived in Sweden for an extended period of time and who were adults when they immigrated to Sweden. The interviews are thematic life stories. Each one of the individuals narrates his or h

Knowing this true stellar motion, spectral shifts; intrinsic to stellar atmospheres can be identified, for instance gravitational redshifts and those caused by, velocity fields on stellar surfaces. The astrometric accuracy is independent. of any spectral
Purpose: We evaluated the effects of beta-adrenoceptor agonists on detrusor hyperreflexia in cerebral infarcted rats. Materials and Methods: To produce cerebral infarction in Sprague-Dawley rats the left middle cerebral artery was occluded by introducing a monofilament nylon thread into the artery. In sham operated rats the same artery was exposed but not occluded. After these operations cystometr
This paper proposes a method for multi-loop PI controller design which can achieve dominant pole placement for two input two output processes. It is an extension of the original dominant pole design (PID Controllers: Theory, Design, and Tuning, Instrument Society of America, Research Triangle park, NC, 1995.) for SISO systems. Unlike its SISO counterpart, where the controller parameters can be obt
Cytogenetic investigation of short-term cultures from two leiomyosarcomas revealed complex karyotypic changes in both cases. The first tumor, a subcutaneous leiomyosarcoma of the knee, had the karyotype 70-80,XY, +X, +Y, +1, +1, +2, +2, +3, +3, +4, +4, +7, +7, +8, +8, +9, +10, +15, +15, +16, +16, +18, +19, +20, +21, +21, +22, +22,t(?;5)(5;21)(?;q35p11;q11), t(?;5)(5;21)(?;q35p11;q11), +del(11)(q22
The pH and salt dependent self-association of hen egg-white lysozyme (HEWL) has been studied extensively, mainly by scattering techniques, but it has proven difficult to distinguish oligomerization from long-range interactions. Because HEWL is the principal model system in studies of protein crystallization, it is important to establish its oligomerization behavior unambiguously. Here, we address
A new approach to calculating the parameters of resonant states is proposed, which also makes it possible to determine the probabilities of the resonant scattering and capture probabilities at the resonant state. This approach is based on the application of the method of configuration interaction, which was proposed for the first time by Fano for an analysis of field ionization of the helium atom.
