Record low beta beating in the LHC

The LHC is currently operating with a proton energy of 4 TeVand beta* functions at the ATLAS and CMS interaction points of 0.6 m. This is close to the design value at 7 TeV ( beta* = 0.55 m) and represented a challenge for various aspects of the machine operation. In particular, a huge effort was put into the optics commissioning and an unprecedented peak beta beating of around 7% was achieved in

High-speed structured planar laser illumination for contrast improvement of two-phase flow images

A high-speed method to remove blurring effects caused by multiple scattering in planar laser images of two-phase flows is demonstrated. The technique is based on structured illumination and is for the first time to our knowledge applied on a dynamic medium. As structured illumination requires three successive images to be recorded and to freeze the flow motion in time, a high-speed laser and imagi

Adaptigation

This article integrates the concepts and notions of climate change adaptation and mitigation in order to formulate the concept of adaptigation as a heuristic strategy for political and professional response to climate change in planning and other realms of climate change response for synergies and efficiencies.

Detection of a typical arson fire scenario – comparison between experiments and simulations

Abstract in UndeterminedBetween one and two school fires occur in Sweden every day. In most cases, arson is the cause of the fire. The most severe fires generally start outside the building and spread up along the façade and into the attic through ventilation openings in the eaves. Linear heat detectors can be placed on façades to detect these types of fires. Such devices detect fire when short-ci

Impact of maternal characteristics on fetal growth in the third trimester: a population-based study

Objectives. To investigate the association between maternal characteristics and fetal growth during the third trimester of pregnancy. Methods. Using a population-based perinatal register, 48,809 term singleton pregnancies were identified for which a routine ultrasound examination in the third trimester was performed between 1995 and 2009. Fetal and infant weight, respectively, were expressed as ge

Contrasting patterns of allochthony among three major groups of crustacean zooplankton in boreal and temperate lakes

The importance of terrestrial-derived organic matter for lake zooplankton communities remains debated, partly because little is known about the basic pathways by which allochthonous carbon is transferred to zooplankton, and whether these vary among the major taxonomic and functional groups. We quantified allochthony of three zooplankton groups (Cladocera, Calanoida, and Cyclopoida) across 18 lakes

Psychometric properties of four fear of falling rating scales in people with Parkinson's disease.

Fear of falling (FOF) is commonly experienced in people with Parkinson's disease (PD). It is a predictor of recurrent falls, a barrier to physical exercise, and negatively associated with health-related quality of life. A variety of rating scales exist that assess different aspects of FOF but comprehensive head-to-head comparisons of their psychometric properties in people with PD are lacking. The

Laminar burning velocity of lean H-2-CO mixtures at elevated pressure using the heat flux method

Laminar burning velocity measurements of 50:50 and 85:15% (by volume) H-2-CO mixtures with O-2-N-2 and O-2-He oxidizers were performed at lean conditions (equivalence ratio from 0.5 to 1) and elevated pressures (1 atm-9 atm). The heat flux method (HFM) is employed for determining the laminar burning velocity of the fuel-oxidizer mixtures. HFM creates a one-dimensional adiabatic stretchless flame w

Conceptual design report for a Beta-Beam facility

The Beta-Beam is a concept of large-scale facility that aims at providing pure electronic neutrino and antineutrino beams for the measurement of v(e) -> v(mu) oscillations. Beta-decaying nuclides are produced in large amounts in a facility of the scale of EURISOL, and are then post-accelerated and stored at large gamma in a racetrack decay ring. We present here a conceptual design of the accelerat

The European postmarketing adult Osteosarcoma Surveillance Study: characteristics of patients A preliminary report

The Scandinavian Sarcoma Group (SSG) registry participates in a multinational postmarketing drug surveillance study evaluating potential medication exposures (including teriparatide) in a population-based series of adult osteosarcoma cases. We present preliminary data from this study. The SSG registry systematically identifies eligible cases in collaboration with regional and national cancer regis

Neutral pion and eta meson production in proton-proton collisions at root s=0.9 TeV and root s=7 TeV

The first measurements of the invariant differential cross sections of inclusive pi(0) and eta meson production at mid-rapidity in proton-proton collisions root s = 0.9 TeV and root s = 7 TeV are reported. The pi(0) measurement covers the ranges 0.4 < p(T) < 7 GeV/c and 0.3 < p(T) < 25 GeV/c for these two energies, respectively. The production of eta mesons was measured at root s = 7 TeV in the ra

Fabrication of a novel electrochemiluminescence glucose biosensor using Au nanoparticles decorated multiwalled carbon nanotubes

Au nanoparticles (nanoAu) with an average diameter of 60 nm were decorated on the surface of multiwalled carbon nanotubes to prepare MWCNTs-nanoAu nano-hybrids. The MWCNTs-nanoAu nano-hybrids were cast on the surface of a glassy carbon electrode and were then further modified with a layer comprising glucose oxidase and chitosan to fabricate a novel electrochemiluminescence (ECL) glucose biosensor.

Differences in serum levels of CB-153 and p,p '-DDE, and reproductive parameters between men living south and north in Norway

Arctic is contaminated with persistent organochlorine pollutants (POPs), and exposure to these compounds may differ between south and north in Norway. POPs may have negative impact on male reproductive characteristics. We compared serum levels of the CB-153 and p,p'-DDE in men who were born and had lived most of their lifetime south and north (close to or above the Arctic Circle) in Norway. We fou

Gene expression in the brain of a migratory songbird during breeding and migration.

We still have limited knowledge about the underlying genetic mechanisms that enable migrating species of birds to navigate the globe. Here we make an attempt to get insight into the genetic architecture controlling this complex innate behaviour. We contrast the gene expression profiles of two closely related songbird subspecies with divergent migratory phenotypes. In addition to comparing differen

Co-owned Local Government Organisations: Conditions for Strategy Development

Local governments tend to join resources and create co-owned organisations to solve the supply of public services. From a strategic perspective on local government cooperation, this paper analyses the conditions for strategy development in a co-owned municipal organisation. The empirical data stem from a longitudinal case study of a Swedish provider of water and sewerage services. We show that dif
