The Large Hadron Collider (LHC) will in 2007 start colliding proton and lead beams at root(s) = 14 TeV and root(S-NN) = 5.5 TeV, respectively. The accelerator and the experiments are under construction and detailed studies of the physics program are being prepared. I will in this paper review the current status of the experiments and the heavy ion physics aspects that are unique at LHC.

Did life change after treatment? How did it change? Evaluations of in-treatment programs for drug abusers are usually designed to discover effects of treatment on the client´s drug use. This report presents a follow-up study with a broader perspective. Rehabilitation from drug abuse is seen as a radical or gradual change of life course and identity, interrelated to changes in social conditions. Ma

Manganese superoxide dismutases catalyze the disproportionation of the superoxide radical anion to molecular oxygen and hydrogen peroxide. Recently, atomic-resolution crystal structures of the reduced and oxidized enzymes have been reported. They show an active site with the manganese ion bound to one aspartate, three histidine residues, and a solvent molecule. In this paper, we combine crystallog

This paper presents data from the Austronesian language Seediq, spoken in taiwan, which has both VOS order and final particles. It will be argued that the coccurrence of these two features is unexpected under a pre-antisymmetric analysis, whereas it is easily captured under an analysis couched in Kayne's Antisymmetry model, under the assumption that VOS order is derived by raising the predicate to

The report contains abstracts of Master theses (examensarbeten) made at the Department of Automatic Control, Lund, during the academic year 84/85. During this year 16 theses were made by 18 students. Most of the theses are written in Swedish with an English abstract.

We investigate the lowest state of a Bose-Einstein condensate with an off-center vortex state that is confined in a rotating harmonic potential. Our results are consistent with the fact that any single off-center vortex is unstable. Furthermore, a vortex state located at the center of the cloud first becomes locally stable as the rotational frequency increases. Finally our study implies the existe

Saito, Quintiere and Williams (1) developed an integral equation derived from quasi-steady thermal flame spread theory to describe spread up a thick solid. Allowance was made in this purely thermal model for a varying rate of pyrolysis and the relationship between flame length and burning rate was linearised. They discussed asymptotic solutions to their equation and derived the requirements for tw

This paper presents an original mathematical framework based on graph theory which is a first attempt to investigate the dynamics of a model of neural networks with embedded spike timing dependent plasticity. The neurons correspond to integrate-and-fire units located at the vertices of a finite subset of 2D lattice. There are two types of vertices, corresponding to the inhibitory and the excitator

The time domain version of the optical theorem is discussed. The theorem relates the sum of the scattered and absorbed energies, for a plane pulse that is scattered from a bounded obstacle, to the far field amplitude in the forward direction. Several fundamental results concerning the scattered and absorbed energies that follow from the theorem and from causality are discussed. Some results are ve

The acetylene-nitrogen system is investigated in a combined theoretical and experimental effort in view of its thermometry applications. Accurate values of the rotational Raman linewidths of acetylene are of crucial importance for the computation of spectra from rotational coherent anti-Stokes Raman scattering (CARS) used for temperature and concentration evaluations. Since the direct measurements

Inclusive jet cross sections are measured in photoproduction at HERA using the H1 detector. The data sample of e(+)p --> e(+) + jet + X events in the kinematic range of photon virtualities Q(2) less than or equal to 1GeV(2) and photon-proton centre-of-mass energies 95 less than or equal to W-gammap less than or equal to 285GeV represents an integrated luminosity of 24.1pb(-1). Jets are defined usi

This chapter focuses on the use of different methods for isolation of alkylresorcinols. Alkylresorcinols are members of a lipid group called non-isoprenoid phenolic lipids. Different aspects of the extraction by classical methods and supercritical CO2 are discussed. Supercritical CO2 extraction of alkylresorcinols from rye bran is discussed for the first time. As compared to the classical extracti

This article outlines an experimental and numerical study of the long-term interaction between silica fume and Portland cement in low-temperature-cured ceramics such as concrete subjected to air, water and sealed curing. For this purpose about 2000 kg of eight qualities of concrete were studied at 4 different ages, each over a period of 90 months. Half of the concretes contained 10% silica fume. P
