Using two epochs of HST/WFPC2 images of the metal-rich globular clusterNGC 6528 we derive the proper motions of the stars and use them toseparate the stars belonging to NGC 6528 from those of the Galacticbulge. The stellar sequences in the resulting colour-magnitude diagramfor the cluster are significantly better determined than in previouslypublished data. From comparison of the colour-magnitude

Background: Fermentation of lignocellulosic biomass is an attractive alternative for the production of bioethanol. Traditionally, the yeast Saccharomyces cerevisiae is used in industrial ethanol fermentations. However, S. cerevisiae is naturally not able to ferment the pentose sugars D-xylose and L-arabinose, which are present in high amounts in lignocellulosic raw materials. Results: We describe

The entire cDNA corresponding to the C-terminal cysteine-rich domain of the human MUC2 apomucin, after the serine- and threonine-rich tandem repeat, was expressed in Chinese-hamster ovary-K1 cells and in the human colon carcinoma cell line, LS 174T. The C-terminus was expressed as a fusion protein with the green fluorescent protein and mycTag sequences and the murine immunoglobulin K-chain signal

Popular Abstract in Swedish Avhandlingen består av två delar. Den första delen behandlar reglering av processer med lång dödtid. Avhandlingen ger förslag på hur regulatorer för dessa processer ska dimensioneras och jämför sedan prestanda hos dessa regulatorer med vanliga PID-regulatorer. Avhandlingens andra del handlar om metoder för automatisk övervakning av reglerkretsar i processindustrin. TvåThe thesis contains two parts, dead-time compensation and performance monitoring. The first part on dead-time compensation is about robust tuning procedures for dead-time compensating controllers (DTC). Both stable and integrating processes are considered. Simple experiments are performed to obtain process models as well as bounds on the allowable bandwidth for stability. The DTCs used have few pa

Two methods for visual evaluation of image quality of clinical radiographs have been compared. In visual grading analysis (VGA) specified anatomical structures in an image are visually compared with the same structures in a reference image, and in a free-response forced error (FFE) experiment - an extension of conventional ROC (receiver operating characteristics) analysis - the objective is to cor

Abstract in French De la métaphore à l’allégorie dans la sémiotique écologique Göran Sonesson Si l’allégorie est une métaphore filée, comme disent les classiques, il faut commencer par étudier cette dernière. Le système de Groupe µ, dont nous avons donné ailleurs une version revue et corrigée, esquive cette terminologie traditionnelle, mais si l’on veut appliquer un tel système à la rhétorique lFrom metaphor to allegory in ecological semiotics Göran Sonesson If allegory is an extended metaphor, as classical rhetoric would have it, we should have to start by studying the latter. The system of the µ group, which I have elsewhere tried to amend and build out, steers clear of this traditional terminology, but if the resulting system should still be relevant to linguistic rhetoric, correlat

This e-book contains contributions from two sessions at the archaeological conference Nordic TAG VIII that took place in Lund in 2005. It is also the first volume of a digital publication, Archaeology @ Lund, published by the Department of Archaeology and Ancient History at Lund University. The two sessions that are published together here are The Practical Aspects of the History of Archaeology an

This review discusses the complicated two-electron dynamics of a helium atom in an intense, short laser pulse. A helium gas in femtosecond laser pulses at long wave lengths (lambda similar to 700 nm) and high intensities (I similar to 10(15) W/cm(2)) produces surprisingly high numbers of He2+ ions. These laser fields cause large and fast electron oscillations, which makes a solution of the time-de

A cultivation strategy combining the advantages of temperature-limited fed-batch and probing feeding control is presented. The technique was evaluated in fed-batch cultivations with E. coli BL21(DE3) producing xylanase in a 3 liter bioreactor. A 20% increase in cell mass was achieved and the usual decrease in specific enzyme activity normally observed during the late production phase was diminishe

One-nucleon removal reactions at relativistic energies have been used as a spectroscopic tool to characterise the ground state properties of several neutron-rich isotopes in the sd-shell. Using the FRS at GSI, the longitudinal momentum distributions of the emerging fragments after one-nucleon removal were measured. The relative contributions of the remaining fragments in their ground and excited s

Denna rapport utgör redovisningen av tredje och sista etappen i ett arbete om utbytbarhet, material- och energiflöden i installationer för byggnader. De tre etapperna är redovisade i varsin rapport och utgör tillsammans en licentiatuppsats. Första etappen i arbetet utgjordes av litteraturstudien "Installationer ur ett livscykelperspektiv" (Rapport (TABK-99/3058) med syftet att redogöra för det a

Rheumatoid arthritis (RA) is a chronic inflammatory disease resulting in destruction of cartilage and bone. The role of the B cells in RA pathogenesis clearly involves autoantibodies. Collagen type II (CII)-specific antibodies have been identified in RA synovium and synovial fluid. The work in this thesis is focused on the role of CII specific antibodies in the initiation and pathogenesis of arthr

This study investigates the role of political journalism in EU constitution-making. More specifically, we ask whether political journalists take an active role in shaping public preferences and opinion on European integration. An analytical framework is developed distinguishing between the critical and the representative function of media opinion-making. Journalists are found to interfere with the

We have shown that electron-spin density can be generated by a dc current flowing across a pn junction with an embedded asymmetric quantum well. Spin polarization is created in the quantum well by radiative electron-hole recombination when the conduction electron momentum distribution is shifted with respect to the momentum distribution of holes in the spin-split valence subbands. Spin current app
