The thesis uses, as a starting point for a discussion of emergency response management, the problem of gradual coordinated adaptation of management functions in relation to an event and its dynamics. Empirical observations and analyses carried out in the research project show that important problemsolving processes not included in, and sometimes diverging from, planning and preparations frequently

A method to study total deposition of aerosol attached radon progeny in children and adults have been validated and used in home environments. Two persons, one child and one adult are tested simultaneously, thus inhaling from the same aerosol and allowing for a direct comparison. The aim of the study was to increase the knowledge of the lung deposition and thereby the knowledge of the radiation do

We study the phase of the atomic polarization in the process of high-order harmonic generation. Its dependence on the laser intensity and the harmonic order induce a frequency variation in time (chirp) respectively of the harmonic pulses and attosecond pulses. We review the recent experimental results on the temporal characterization of the harmonic emission and show that measurements performed us

Popular Abstract in Swedish Denna avhandling sammanfattar arbete där tidsupplöst röntgendiffraktion har använts för att undersöka kristallina material och studera dynamiken hos fononer och fasövergångar. Röntgendiffraktion är standardverktyget för stukturbestämning på en atomär skala. Det har använts länge och har framgångsrikt hjälp vetenskapsmän att bestämma strukturen hos en stor mängd materiaThis thesis summarizes work in which time-resolved X-ray diffraction has been used to probe crystalline materials, thereby revealing the dynamics of phonons and phase transitions. X-ray diffraction is the standard tool in investigations of structure on the atomic scale. It has been used for a long time, and has successfully helped scientists to find the structure of a wide range of materials. The

PURPOSE: To describe a fatal case of late aortic perforation by an endograft-anchoring stent. METHODS AND RESULTS: A 69-year-old woman presented 2 years after thoracoabdominal aneurysm repair with a 9-cm dilatation of the descending thoracic aorta proximal to the conventional aortic graft. A 38-mm Dacron graft with multiple Gianturco Z-stents sutured inside was placed transluminally across the aor

The process of becoming an Ig-producing plasma cell takes the mature B cell through the germinal center, where Ig genes are diversified through somatic hypermutation and class switch recombination. To more clearly define functional characteristics of the germinal center dark zone centroblasts and the light zone centrocytes, we have performed expression analysis of the CD77(+) and CD77(-) populatio

Objective: The aim of this study was to test the feasibility and accuracy of transthoracic Doppler echocardiography measurement of coronary flow reserve (CFR) in the left anterior descending coronary artery (LAD) territory in the clinical setting of the acute coronary syndrome. Methods: Transthoracic Doppler echocardiography measurements of CFR were made in 42 consecutive patients in the distal LA

Strong superlattice effects are reported on E(k(vertical bar vertical bar)) band dispersions measured by angle-resolved photoemission on W(3 3 1) and W(5 5 1), and graphene nanostripes on Ni(7 7 1). A splitting of the dispersions with reciprocal superlattice vector G = 2 pi/L is observed for a surface resonance on W(3 3 1) and W(5 5 1) and for pi-states of graphene/Ni(7 7 1). Photon-energy-depende

Huntington's disease is an autosomal dominant neurodegenerative disorder caused by an expanded CAG repeat. It is characterized by motor and cognitive disturbances, as well as cellular dysfunction and loss in the basal ganglia and the cerebral cortex. The mutant protein huntingtin aggregates in cells. The toxicity of mutant huntingtin, or the loss of its normal function, causes disruption of cellul

Using the particle-rotor model in which one high-j quasiparticle is coupled to the core of triaxial shape, wobbling excitations are studied. The family of wobbling phonon excitations can be characterized by: (a) very similar intrinsic structure while collective rotation shows the wobbling feature; (b) strong B(E2;I-->I-1) values for Deltan(w)=1 transitions where n(w) expresses the number of wobbli

Artikeln behandlar muralmålningarna i Borgmästarehuset i Ystad, som 1907 demonterades och flyttades till museiområdet i staden. De kan av förfataren med hjälp av fotografisk dokumentation beläggas på samma plats före rivningen, och de dateras med hjälp av träsnitt som kan ha fungerat som förlagor till 1500-talets senare del. Deras ikonografi, kring Kristi passionshistoria, och deras funktion i en

The adaptation of three allopatric populations of a generalist moth, Operophtera brumata (L.), on two tree species, Prunus padus (L.) and Quercus robur (L.) which represent the extremes of the timing of budburst in spring, was studied in Finland and Sweden. The synchrony of the hatching and budbursting was monitored, and its importance to dispersal and growth of larvae was assessed by rearing coho
