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

Accuracies reached in space astrometry now permit. the accurate determination of astrometric radial velocities. without any use of spectroscopy. 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.

Background: It has been suggested that neuromuscular function is of importance in the overall outcome after anterior cruciate ligament (ACL) injury. Hypothesis: Good neuromuscular function can be achieved and maintained over time in subjects with ACL injury treated with rehabilitation and activity modification but without reconstructive surgery. Study Design: Case series; Level of evidence, 4. Met

Aims and Methods: The pulmonary and vascular effects of endothelin-1 receptor activation were studied in isolated perfused and ventilated lung preparations from rat. The responses to endothelin-1 (ET-1) and the endothelin B (ETB) receptor agonist sarafotoxin 6c (S6c) were characterized using the endothelin A (ETA)-receptor antagonist FR 139317, the ETB-receptor antagonist BQ 788 and the combined E

When converting fractional (percentage) depth doses to tissue-phantom ratios, one must use a factor that accounts for the different source-to-point distances. Two minor correction factors are also involved. One is the ratio of total to primary dose at the two different distances from the source, for the same depth and field size. This factor is usually ignored. It was determined experimentally tha

The effects of addition of Schwann cells on peripheral nerve regeneration through a novel graft material-the tendon autograft-and a conventional freeze-thawed muscle graft, were studied in the rat sciatic nerve. Adult Schwann cell cultures were established from predegenerated nerves. The Schwann cells were added to the autologous grafts by coculture (tendon autograft) or injection (freeze-thawed m
