Gamma-ray lines from Sn-103 have been identified for the first time using EUROBALL and ancillary detectors. The level scheme of Sn-103 has been established by means of particle-gated gamma gamma coincidences. The energy spacing between the g(7/2) and d(5/2) neutron single-particle orbitals is determined from the excited states in Sn-103.

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

Electron mean free path (MFP) was determined by the angular resolved photoemission in 10-40 eV energy range for GaAs(100)-c(4 x 4) by the overlayer method. The investigation was based on the attenuation of the normal photoemission intensity of the Al 2p line from the molecular-beam-epitaxy grown GaAlAs layer buried four monolayers of GaAs below the surface. The energy dependence of the MFP shows a

Objectives: To present an analysis of futility that is useful in the clinical setting. Design: Literature review. Material and methods: According to Medline more than 750 articles have been published about medical futility. Three criteria (language, time period, and the authors expressed their own opinions) singled out 43 of them. The authors opinions about futility were analysed using the scheme:

Large eddy simulations of thermal plume in two different scenarios have been carried out using a self-developed parallel computational fluid dynamics (CFD) code, SMAFS (Smoke Movement And Flame Spread), with subgrid-scale turbulence modeled using the Smagorinsky model. Two different initial conditions were used in the simulations, and the results were compared to show that the initial condition ha

Many visual cues for surface reconstruction from known views are sparse in nature, e.g., specularities, surface silhouettes, and salient features in an otherwise textureless region. Often, these cues are the only information available to an observer. To allow these constraints to be used either in conjunction with dense constraints such as pixel-wise similarity, or alone, we formulate such constra

There are several factors that influence the radiologist's ability to detect a specific structure/lesion in a radiograph. Three factors that are commonly known to be of major importance are the signal itself, the system noise and the projected anatomy. The aim of this study was to determine to what extent the image background acts as pure noise for the detection of subtle lung nodules in five diff

Riskanalysen har genomförts av institutionen för brandteknik, Lunds tekniska högskola, i samarbete med räddningstjänsten i Jönköping. Riskanalysen gjordes på uppdrag av Statens räddningsverk och ingår som en del i deras projekt om kommunal riskhantering. De inblandade har från brandteknik varit Göran Holmstedt (projektledare), och Jan-Erik Öst. Från räddningstjänsten i Jönköping har Clas Lövgren d

The transition rates of the intercombination lines 2s2p(3 5)S(2)(0)-->2s(2)2p(2 3)P(1,2) are computed using a systematic configuration interaction method (SCIV3). The calculated lifetime of the upper S-5(2)o, level is in excellent agreement with a recent experiment. The branching ratio of the two lines is very different from earlier, less accurate theoretical values.

An hepatitis A epidemic among 36 persons, mainly drug addicts, occurring over an 18-week period, is described. There were indications that smuggling and transportation of narcotic drugs in the rectum started the outbreak, either through direct contamination of the drug or manipulation of the drug resulting in contaminated fingers.

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

The kinetics of dipolar nonradiative energy transfer (DET) between dyes confined to the core−corona interface region of poly(isoprene-b-methyl methacrylate) block copolymers (PI−PMMA) in acetonitrile was analyzed using a new distribution model for energy transfer in spherical micelles. The distribution of block junction points was described by the model of Helfand and Tagami (HT) for the strong se

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
