New measurements of radiative lifetimes of four 3d65s levelsin Fe II at about 10 eV are presented along with absolute oscillator strengths for twenty 4p-5s transitions involving the four levels. The experimental measurements are compared with two different sets oftheoretical calculations. The lines are of particular interest in the modeling of HLyalpha pumped fluorescence of Fe II in as

The filtering, prediction and smoothing problems as well as the linear quadratic control problems can very generally be formulated as operator equations using basic linear algebra. The equations are of Fredholm type II and difficult to solve directly. It is shown how the operator can be factorized into two Volterra operators using a matrix Riccati equation. Recursive solution of these triangular o
A derivation for a polarized CCFM evolution equation which is suitable to describe the scaling behavior of the unintegrated polarized gluon density is given. We discuss the properties of this polarized CCFM equation and compare it to the standard CCFM equation in the unpolarized case.
In the narrow offshore border zone between Germany and Denmark, 550 km of high-density 3.5-kHz subbottom seismic reflection profiles were recorded within a 70-km(2) area in order to reconstruct the seismic stratigraphy of late Pleistocene to early Holocene lacustrine and fluvial environments. Using detailed line drawings, seismic facies analyses and a hierarchy of bounding surfaces, a depositional
In this thesis, we study load balancing and overload control in two distributed architectures: Distributed Object Computing (DOC) systems and Services-oriented Architecture (SOA) systems. While DOC and SOA have differences in terms of implementation, they are similar from a performance viewpoint. In both DOC and SOA, users access software applications distributed on multiple processing nodes. The
Human embryonic stem cells (hESCs) have been proposed as a source of dopamine (DA) neurons for transplantation in Parkinson's disease (PD). We have investigated the effect of in vitro predifferentiation on in vivo survival and differentiation of hESCs implanted into the 6-OHDA (6-hydroxydopamine)-lesion rat model of PD. The hESCs were cocultured with PA6 cells for 16, 20, or 23 days, leading to th
Techniques of isothermal microcalorimetry have been much improved during the past two decades. In addition to their use in fundamental research, applications of practical importance have been established in some areas. However, no significant use of isothermal microcalorimetry has yet been seen in practical applications of biology, despite many methodological studies reported from that area. The m
Stationary and mobile field gamma spectrometry is a useful tool for rapid estimation of environmental radioactivity inventories on and in the ground. A weak point however, is that the depth distribution of the activity in the ground must be known in order to calculate the true activity per unit area or unit mass from an observed photon fluence rate. A promising method for converting incoming spect
The issue of environmental implications of logistics systems is one of the future challenges to logisticians. The purpose of this paper is to explore the logistics and supply chain management discipline to see how the scientific community handles this challenge. Observations in the primary literature revealed that there are weak ties between the logistics/SCM discipline and the environmental disci
Popular Abstract in Swedish Avhandlingen behandlar två områden. Dels kopplingen mellan import, konkurrens och produktivitetsutveckling i Sverige och inom EU, dels effekten av inrättandet av så kallade exportzoner i u-länder, det vill säga särskilda områden som omfattas av olika incitament för att locka utländska företag att etablera en exportorienterad verksamhet i landet. Exempelvis så kan tullfrThis thesis addresses empirically the interplay among international trade, foreign direct investment (FDI) and domestic market conditions, and its impact on competition, growth, exports and technology diffusion. Chapter two considers the potential relation between regional integration and productivity growth for the case of the European Union (EU). It is found that imports from other members is po
Polysulfones carrying benzoyl(difluoromethylenephosphonic acid) side chains were prepared and investigated for use as proton-conducting fuel-cell membranes. In the first step, polysulfones were lithiated and reacted with methyl iodobenzoates to prepare p- and o-iodobenzoyl polysulfones. Next, the phosphonated polysulfones were prepared via CuBr-mediated cross-coupling reactions between the iodinat
This paper presents results from the analysis of the calibration results from the 1997 single burning item (SBI) test round-robin. The influence of the method of determining delay times and response times for the parameters involved in the heat release rate (HRR) calculation, on the overall result of the HRR and the FIre Growth RAte (FIGRA) index is shown. A procedure to determine response times a
