Self-desiccation occurs in all types of concrete due to the chemical shrinkage that takes place when water is attached to the cement. In High Performance Concrete the low porosity makes the effect of self-desiccation much more pronounced. This paper presents a summary of a Nordic Seminar on Self-Desiccation in Concrete held in Lund. For this purpose aspects of mix design, curing conditions, desicc

Articles about the value of literature, based on lectures given at the conference "The Value of Literature. The contribution of literature, literary history and theory to cultural, ethical and social development", held at Vitterhetsakademien, Stockholm Nov 2004.

Double-tagged interactions of photons with virtualities Q(2) between 10 GeV2 and 200 GeV2 are studied with the data collected by DELPHI at LEPII from 1998 to 2000, corresponding to an integrated luminosity of 550 pb(-1). The gamma*gamma* -> mu(+)mu(-) data agree with QED predictions. The cross-section of the reaction gamma*gamma* -> hadrons is measured and compared to the LO and NLO BFKL calculati

Background: Pancreatic cancer is generally associated with a poor prognosis and often diagnosed in an advanced stage. The aim of the present study was to evaluate gemcitabine treatment concerning prognostic factors, clinical benefit, tolerance/ toxicity and survival. Methods: Patients with surgically nonresectable, locally advanced or metastatic pancreatic cancer treated with gemcitabine were incl

Resonant Auger spectra of O-2 clusters excited at the O1s edge are reported. After excitation to the repulsive 1s(-1)3 sigma* state, the resulting resonant Auger spectrum displays features that remain constant in kinetic energy as the photon energy is detuned. The shift between known atomic fragment features and these features is consistent with that observed for atoms and clusters in singly charg

Abstract in French Cet article pose la question de savoir s’il existe une corrélation entre le niveau grammatical et le niveau lexical dans la production écrite d’apprenants de français langue étrangère. Nous avons appliqué un certain nombre d’indices quantitatifs et lexicaux et un indice grammatical à 40 textes en français, écrits par deux groupes d’apprenants adultes suédophones se situant à desThe paper addresses the question of whether there is a correlation between the grammatical developmental level and the lexical developmental level in the written production of learners of French as a foreign language. We have applied a number of quantitative and lexical measures and one grammatical measure to 40 texts in French written by two groups Swedish adults with different proficiency levels

The phase behavior over the entire concentration range for the system didodecyldimethylammonium bromide (DDAB)-sodium taurodeoxycholate (STDC)-water, at 25 degrees C, has been investigated, with emphasis on the DDAB-rich part. Polarizing microscopy, SAXS, H-2 NMR and H-1 self-diffusion NMR have been used in combination as probing techniques for phase behavior and microstructure. The system forms f

Post-shift and next-morning urine was sampled from workers exposed to hexahydrophtalic anhydride (HHPA), an epoxy hardener, sensitising at low exposure levels. Exposure levels of HHPA in air (gas chromatography, GC) in the range of 30-270 micrograms/m3 corresponded to urinary concentrations of 0.9-2.8 mumol hexahydrophthalic acid (HHP acid; GC-mass spectrometry)/mmol creatinine. In the morning sam

Objective. Selective leukocyte apheresis is a new type of non-pharmacological treatment for patients with active ulcerative colitis and Crohn's disease. Preliminary data have indicated that this type of therapy is safe and efficacious, and large sham-controlled studies are currently in progress. In Scandinavia, a substantial number of patients with chronic inflammatory bowel disease have already r

A novel prenylated isoflavanone, sigmoidin I, has been isolated from the roots of Erythrina sigmoidea, in addition to the known isoflavones, corylin and neobavaisoflavone and the known pterocarpan, phaseollidin. Its structure was established as 7,4'-dihydroxy-3'-methoxy-5'-(3-methylbut-2-enyl) isoflavanone by means of spectroscopic analyses and chemical transformations. Neobavaisoflavone displayed

I uppsatsen jämförs Rydbergs artiklar med hans roman Fribytaren på Östersjön. Kyrkokritiken är allvarligare, djupare och bredare i romanen trots att artiklarna är mer "rakt på sak".

Measurements of surface temperature and mass loss of decomposing construction materials during rapid pyrolysis are presented. Experiments have been performed With samples of low-density fiberboard. medium-density fiberboard,. particleboard and poly(methyl methacrylate) in a single particle reactor at temperatures between 300degrees and 600degreesC. Ultraviolet laser light was used to excite microm

Popular Abstract in Swedish Hur uppfattar predikanter sitt predikouppdrag och hur uppfattar åhörare predikan? Hur förhåller sig dessa uppfattningar till olika predikoteoretiska perspektiv? Vilka konsekvenser får kunskapen om predikanters och åhörares uppfattningar för predikan? I undersökningen kartläggs hur de som är engagerade i predikosituationen tänker om predikan. Två grupper är då särskilt This study describes, systematizes and analyses the variations of preachers' conceptions of their mission to preach and their listeners' conceptions of the sermon. It does so in a phenomenographic and theological perspective. The conceptions of preachers and their listeners of the mission to preach and the sermon respectively are investigated by way of interviews. The basic issues are what differe

We demonstrate the use of nanoimprint lithography to define arrays of vertical InP nanowires. Each nanowire is individually seeded from a catalyzing gold particle and then grown via vapor-liquid-solid growth in a metal-organic vapor phase epitaxy system. The diameter and position of each nanowire can be controlled to create engineered arrays, demonstrated with a hexagonal photonic crystal pattern.

Terminal pumping has recently been installed in the Lund tandem Pelletron electrostatic accelerator. The equipment allows a higher gas density in the stripper and an improved vacuum in the accelerator tubes compared to the former system. This improvement has led to an increased beam transmission and to superior measurements for our accelerator mass spectrometry programme. The pressure profile of t
