Centrality dependence of the pseudorapidity density distribution for charged particles in Pb-Pb collisions at root s(NN)=2.76 TeV

We present the first wide-range measurement of the charged-particle pseudorapidity density distribution, for different centralities (the 0-5%, 5-10%, 10-20%, and 20-30% most central events) in Pb-Pb collisions at root s(NN) = 2.76 TeV at the LHC. The measurement is performed using the full coverage of the ALICE detectors, -5.0 < eta < 5.5, and employing a special analysis technique based on collis

Adjustable ECR Ion Source Control System: Ion Source Hydrogen Positive Project

ISHP (Ion Source Hydrogen Positive) project consists of a highly versatile ECR type ion source. It has been built for several purposes, on the one hand, to serve as a workbench to test accelerator related technologies and validate in-house made developments, at the first stages. On the other hand, to design an ion source valid as the first step in an actual LINAC. Since this paper is focused on th

Racemic tricarbonyl(eta 6-7-methoxyflavan)chromium(0)

In the title compound [systematic name: tricarbonyl(eta 6-7-methoxy-2-phenyl-3,4-dihydro-2H-1-benzopyran)chromium(0)], [Cr(C16H16O2)(CO)(3)], the Cr(CO)(3) unit is coordinated by the phenylene ring of the flavan ligand, exhibiting a three-legged piano-stool conformation, with a point to plane distance of 1.750 (1) A. The phenyl ring is twisted away from the fused ring system by 36.49 (5)degrees (r

Cryogelation of molecularly imprinted nanoparticles: A macroporous structure as affinity chromatography column for removal of β-blockers from complex samples.

In this work, a new macroporous molecularly imprinted cryogel (MIP composite cryogel) was synthesized by glutaraldehyde cross-linking reaction of poly(vinyl alcohol) (PVA) particles and amino-modified molecularly imprinted core-shell nanoparticles. The MIP core-shell nanoparticles were prepared using propranolol as a template by one-pot precipitation polymerization with sequential monomer addition

Measurement of dijet production in diffractive deep-inelastic scattering with a leading proton at HERA

The cross section of diffractive deep-inelastic scattering ep -> eXp is measured, where the system X contains at least two jets and the leading final state proton is detected in the H1 Forward Proton Spectrometer. The measurement is performed for fractional proton longitudinal momentum loss x(P) < 0.1 and covers the range 0.1 < vertical bar t vertical bar < 0.7 GeV2 in squared four-momentum transf

The Phenomenology of Specialization of Criminal Suspects

A criminal career can be either general, with the criminal committing different types of crimes, or specialized, with the criminal committing a specific type of crime. A central problem in the study of crime specialization is to determine, from the perspective of the criminal, which crimes should be considered similar and which crimes should be considered distinct. We study a large set of Swedish

Reduced-Complexity Receivers for Strongly Narrowband Intersymbol Interference Introduced by Faster-than-Nyquist Signaling

We propose new M-algorithm BCJR (M-BCJR) algorithms for low-complexity turbo equalization and apply them to severe intersymbol interference (ISI) introduced by faster than Nyquist signaling. These reduced-search detectors are evaluated in simple detection over the ISI channel and in iterative decoding of coded FTN transmissions. In the second case, accurate log likelihood ratios are essential and

The upgraded photon tagging facility at the MAX IV Laboratory

A description is given of the upgraded photon tagging facility at the MAX IV Laboratory. Two magnetic spectrometers are used to momentum analyze post-bremsstrahlung electrons. The tagged photon range extends from 10 to 180 MeV with an energy resolution of about 300 keV. The system has been operated at rates up to 4 x 10(6) photons s(-1) MeV (-1). Different diagnostic tools are described as well as

Pointwise hyperbolicity implies uniform hyperbolicity

We provide a general mechanism for obtaining uniform information from pointwise data. For instance, a diffeomorphism of a compact Riemannian manifold with pointwise expanding and contracting continuous invariant cone families is an Anosov diffeomorphism, i.e., the entire manifold is uniformly hyperbolic.

Nonlinear lateral control strategy for nonholonomic vehicles

This paper proposes an intuitive nonlinear lateral control strategy for trajectory tracking in autonomous nonholonomic vehicles. The controller has been implemented and verified in Alice, Team Caltech's contribution to the 2007 DARPA Urban Challenge competition for autonomous motorcars. A kinematic model is derived. The control law is described and analyzed. Results from simulations and field test

Ritualer i koncentrationslägret. Avståndstagande, moral och anpassning i före detta lägerfångars berättelser från Bosnien

I denna artikel analyserar muntligt gestaltade erfarenheter hos före detta lägerfångar som placerades i koncentrationsläger i början av kriget i Bosnien och Hercegovina under 1990-talet. Artikeln bygger på 13 intervjuer med före detta lägerfångar och nära anhöriga som numera bor i Sverige, Danmark och Norge. Syftet med artikeln är att beskriva de sociala interaktionsritualer som återberättas efterIn this article portrayed experiences of former inmates that were placed in the concentration camps in the beginning of the war in Bosnia and Herzegovina in the 1900s are being analyzed. The article is based on 13 interviews with former inmates and close relatives that currently live in Sweden, Denmark and Norway. The purpose with the article is to describe the social interaction rituals that are

Contact Allergy to Acrylates

Popular Abstract in Swedish Akrylatallergi Plastmaterial består av stora molekyler som kallas polymerer samt tillsatsämnen som tillsätts för att modifiera materialets egenskaper. Polymerer bildas när det sker en stegvis reaktion mellan monomerer så att större molekyler bildas. Allergiframkallande ämnen i plastsystem kan vara monomererna, härdarna, modifierarna eller andra tillsatsämnen. AkrylaterAcrylate contact allergy has been frequently reported since the 1970s, with hundreds of articles published in dermatology journals so far. The purpose of this thesis was to investigate the frequency of contact allergy to acrylates / methacrylates in patients with exposure to industrial, dental and nail uses of these substances. We also aimed to investigate the clinical and chemical aspects of pa

Diminishing return of investment in genetic diversity

Motive: Priorities in conservation management are often difficult to determine because we lack comparable biodiversity metrics. So that actions can be cost-effective, conservation decision-making and management needs such metrics. Question: What suitable metrics can compare efforts and investments in biodiversity conservation? How can established measures of genetic diversity be combined with the

Segerns väv. Djurornamentik och skaldediktning under yngre järnålder.

This article is about the cognitive meanings of animal ornamentation in a long term perspective. Special focus is upon the relation between the images of animal ornamentation and verbal expressions in the heroic skaldic poetry from the early medieval period. The article also discuss animal ornamentation in relation to gender.

Maternal use of antihypertensive drugs in early pregnancy and delivery outcome, notably the presence of congenital heart defects in the infants

Purpose To investigate the association between maternal use of antihypertensives in early pregnancy and delivery outcome, notably infant congenital malformations. Methods A cohort study of 1,418 women who had used antihypertensive drugs in early pregnancy but had no diabetes diagnosis were identified from the Swedish Medical Birth Register. Results There was an excess risk for placental abruption,

Perpetuating "New Public Management' at the expense of nurses' patient education: a discourse analysis

This study aimed to explore the conditions for nurses' daily patient education work by focusing on managers' way of speaking about the patient education provided by nurses in hospital care. An explorative, qualitative design with a social constructionist perspective was used. Data were collected from three focus group interviews and analysed by means of critical discourse analysis. Discursive prac
