Om social sårbarhet i samband med extraordinära händelser - en intervjustudie i 12 kommuner

The aim of this report is to study how the authorities in twelve Swedish municipalities consider social vulnerability in disasters. The study is based on telephone interviews with ten officials responsible for safety and risk analysis and with ten officials responsible for social and psychological support after disasters. Three group interviews about the support for affected citizens after the sto

Determination of heavy quark non-perturbative parametersfrom spectral moments in semileptonic B decays

Moments of the hadronic invariant mass and of the lepton energy spectra in semileptonic B decays have been determined with the data recorded by the DELPHI detector at LEP. From measurements of the inclusive b-hadron semileptonic decays, and imposing constraints from other measurements on b- and c-quark masses, the first three moments of the lepton energy distribution and of the hadronic mass distr

Search for charged Higgs bosons in e(+)e(-) collisions root s=189-202 GeV

A search for pair-produced charged Higgs bosons was performed in the high energy data collected by the DELPHI detector at LEP II at centre-of-mass energies from 189 GeV to 202 GeV. The three different final states, taunutaunu, c (s) over bar(c) over bars and c (s) over bar taunu were considered. New methods were applied to reject wrong hadronic jet pairings and for the tau identification, where a

New Band Structures and an Unpaired Crossing in 78Kr

High-spin states in Kr-78 were studied using the Ni-58(Na-23,3p) reaction at 70 MeV and the Ni-58(Si-23,alpha 4p) reaction at 130 MeV. Prompt gamma-gamma coincidences were measured using the Pitt-FSU detector array and the GAMMASPHERE-MICROBALL array. Results from these experiments have led to 26 new excitation levels, some of which have been grouped into 3 new bands. Spins were assigned based on

The effect of the non-ionic contrast medium iohexol on glomerular and tubular function in diabetic patients

The effect of the non-ionic contrast medium iohexol (Omnipaque) on renal function was investigated in diabetic patients with signs of peripheral ischaemia. Forty-six patients, 70 +/- 11 years (mean +/- SD) old, age at diabetes diagnosis 53 +/- 17 years, and with varying degrees of diabetic nephropathy were studied before 1, 2, and 30 days after aortobifemoral arteriography. Serum creatinine, creat

Purification and characterization of chitinases from the nematophagous fungi Verticillium chlamydosporium and v. suchlasporium

Culture filtrates of the nematophagous fungi Verticillium chlamydosporium and V. suchlasporium growing on colloidal chitin showed increasing chitinolytic activity and production of two (32- and 43-kDa) main proteins. Maximum activity was found 18-20 days after inoculation, but V. suchlasporium always displayed higher activity. Zymography of such filtrates on carboxymethyl-chitin-Remazol brilliant

Insulating surface layer on single crystal K3C60

Using angle-dependent photoemission spectra of core and valence levels we show that metallic, single crystal K3C60 is terminated by an insulating or weakly-conducting surface layer. We attribute this to the effects of strong intermolecular correlations combined with the average surface charge state. Several controversies on the electronic structure are thereby resolved.

The Bismuth Abundance in the HGMN Stars chi Lupi and HR 7775 and Improved Atomic Data for Selected Transitions of BI I, BI II, and BI III

High-resolution spectra of the chemically peculiar HgMn stars chi Lupiand HR 7775, obtained with the Hubble Space Telescope/Goddard HighResolution Spectrograph, are investigated for their abundance of bismuthby comparison with LTE synthetic spectrum modeling. HR 7775, previouslyknown from International Ultraviolet Explorer spectra to display stronglines of Bi II, is determined to have bismuth pres

Experiments with artificial haptic perception in a robotic hand

The LUCS Haptic Hand I together with a set of haptic models is the first in a series of projects aimed at studying haptic perception for building several robotic hands together with cognitive computational models of the corresponding human neurophysiology. The haptic systems have been trained and tested with a set of objects consisting of balls and cubes, and the activation in the modules correspo

Linear Interpolation D/A Converter Applied to Direct Digital RF Modulators

This thesis deals with techniques for the full integration of radio frequency (RF) transmitter with CMOS technology. The theory and implementation of high performance digital-to-analog converters (DACs) for radio frequency (RF) transmitters have been studied. A linear interpolation DAC architecture is proposed. By employing the linear interpolation, the attenuation of DAC's image components is sig

Multiple-window cepstrum analysis for estimation of periodicity

Multiple windows have been used in spectrum analysis to reduce variance. In this paper, a multiple-window approach is suggested in cepstrum analysis, where the period of the system response should be estimated. The logarithm of the spectrum as well as the liftering are approximated by a division of two multiple-window spectra. The method is useful especially in the case of short periods of the per

Area averaging of land surface-atmosphere fluxes in NOPEX: challenges, results and perspectives

The NOPEX experimental campaigns dealt with the land-surface-atmosphere exchange of momentum, heat, water and CO2 on local and regional scales. In this paper emphasis is put on the NOPEX experiences with respect to the spatial integration of fluxes of momentum, heat, humidity and CO2 over the mosaic of forest, agricultural land, lakes and mires that make up the southern part of the NOPEX area. It
