- ALICE (A Large Ion Collider Experiment) is a general-purpose, heavy-ion detector at the CERN LHC which focuses on QCD, the strong-interaction sector of the Standard Model. It is designed to address the physics of strongly interacting matter and the quark-gluon plasma at extreme values of energy density and temperature in nucleus-nucleus collisions. Besides running with Pb ions, the physics programme includes collisions with lighter ions, lower energy running and dedicated proton-nucleus runs. ALICE will also take data with proton beams at the top LHC energy to collect reference data for the heavy-ion programme and to address several QCD topics for which ALICE is complementary to the other LHC detectors. The ALICE detector has been built by a collaboration including currently over 1000 physicists and engineers from 105 Institutes in 30 countries, Its overall dimensions are 16 x 16 x 26 m(3) with a total weight of approximately 10 000 t. The experiment consists of 18 different detector systems each with its own specific technology choice and design constraints, driven both by the physics requirements and the experimental conditions expected at LHC. The most stringent design constraint is to cope with the extreme particle multiplicity anticipated in central Pb-Pb collisions. The different subsystems were optimized to provide high-momentum resolution as well as excellent Particle Identification (PID) over a broad range in momentum, up to the highest multiplicities predicted for LHC. This will allow for comprehensive studies of hadrons, electrons, muons, and photons produced in the collision of heavy nuclei. Most detector systems are scheduled to be installed and ready for data taking by mid-2008 when the LHC is scheduled to start operation, with the exception of parts of the Photon Spectrometer (PHOS), Transition Radiation Detector (TRD) and Electro Magnetic Calorimeter (EMCal). These detectors will be completed for the high-luminosity ion run expected in 2010. This paper describes in detail the detector components as installed for the first data taking in the summer of 2008.

Konferensbidrag (refereegranskat)abstract
- The INNOTRACK project (www.innotrack.eu) is a European research project within the 6th Framework Programme. The aim of the INNOTRACK project is to deliver innovative track-related solutions to reduce life cycle costs and improve the reliability, availability, maintainability and safety of the rail sector. The current paper gives an overview of work in INNOTRACK of relevance for the CM2009 conference. The work presented in this paper focuses on innovative processes and methodologies. Topics discussed concern rail selection, installation, inspection and maintenance and also the optimisation of switches and crossings. Finally a discussion on technical, logistical and economical verifications of proposed solutions is presented. Many of the topics included in this overview paper are presented in detail in other contributions to the CM2009 conference.

Tidskriftsartikel (refereegranskat)abstract
- Wood fibres constitute a renewable raw material for the production of novel biomaterials. The development of efficient methods for cellulose surface modification is essential for expanding the properties of wood fibres for increased reactivity and compatibility with other materials. By combining the high affinity between xyloglucan and cellulose, the unique mechanistic property of xyloglucan endo-transglycosylases (XET, EC 2.4.1.207) to catalyze polysaccharide-oligosaccharide coupling reactions, and traditional carbohydrate synthesis, a new system for the attachment of a wide variety of functional groups to wood pulps has been generated. An overview of recent developments is presented in the context of the structure, physical properties, and historical applications of xyloglucan.
