Developments in optics and performance at BL13-XALOC, the macromolecular crystallography beamline at the Alba Synchrotron

BL13-XALOC is currently the only macromolecular crystallography beamline at the 3 GeV ALBA synchrotron near Barcelona, Spain. The optics design is based on an in-vacuum undulator, a Si(111) channel-cut crystal monochromator and a pair of KB mirrors. It allows three main operation modes: a focused configuration, where both mirrors can focus the beam at the sample position to 52 mu m x 5.5 mu m FWHM

Incidence of hereditary amyloidosis and autoinflammatory diseases in Sweden: endemic and imported diseases

Background: Amyloidoses are a heterogeneous group of progressive diseases caused by tissue deposition of misfolded proteins. According to the International Classification of Diseases, hereditary amyloidosis is divided into neuropathic and non-neuropathic forms. In Sweden, neuropathic heredofamilial amyloidosis has been identified as familial amyloidotic polyneuropathy (FAP), a fatal disease that i

Molecular basis of coagulation factor V deficiency caused by the R1698W inter-domain mutation

Coagulation factor V (FV) deficiency is characterised by variable bleeding phenotypes and heterogeneous mutations. To add new insights into the FV genotype-phenotype relationship, we characterised the R1698W change in the A3 domain, at the poorly investigated interface with the A2 domain. The FV R1698W mutation was responsible for a markedly reduced expression level (10% of FV-WT) and specific act

Lattice Structures of Precoders Maximizing the Minimum Distance in Linear Channels

This paper investigates linear precoding over nonsingular linear channels with additive white Gaussian noise, with lattice-type inputs. The aim is to maximize the minimum distance of the received lattice points, where the precoder is subject to an energy constraint. It is shown that the optimal precoder only produces a finite number of different lattices, namely perfect lattices, at the receiver.

Composition and function of cytochrome c biogenesis System II.

Organisms employ one of several different enzyme systems to mature cytochromes c. The biosynthetic process involves the periplasmic reduction of cysteine residues in the heme c attachment motif of the apocytochrome, transmembrane transport of heme b and stereospecific covalent heme attachment via thioether bonds. The biogenesis System II (or Ccs system) is employed by β-, δ- and ε-proteobacteria,

One-dimensional pion, kaon, and proton femtoscopy in Pb-Pb collisions at root(NN)-N-S=2.76 TeV

The size of the particle emission region in high-energy collisions can be deduced using the femtoscopic correlations of particle pairs at low relative momentum. Such correlations arise due to quantum statistics and Coulomb and strong final state interactions. In this paper, results are presented from femtoscopic analyses of pi(+/-) pi(+/-), K-+/- K-+/-, K-S(0) K-S(0), pp, and (pp) over bar correla

High incidence of septic shock caused by Streptococcus pneumoniae serotype 3-a retrospective epidemiological study

Background: More than 90 immunologically distinct serotypes of Streptococcus pneumoniae exist, and it is not fully elucidated whether the serotype is a risk factor for severity of invasive pneumococcal disease (IPD). Our hypothesis is that serotypes differ in their capacity to cause septic shock. Methods: We performed a retrospective study in Southern Sweden based upon 513 patients with IPD in the

Large-eddy simulation on the effect of injection pressure and density on fuel jet mixing in gas engines

Direct injection (DI) natural gas engines are modern engine concepts providing clean combustion and high fuel efficiency. Even at high injection pressures, such engines operate at heterogeneous/stratified fuel/air mixture conditions due to the relatively short mixing time of the fuel jet. The sub-optimal fuel-air mixture results in emissions of unburnt hydrocarbon (UHC). In particular, one of the

Investigating practice variation in a changing primary care. A multilevel perspective on The Skaraborg Primary Care Database

Popular Abstract in Swedish ”Practice variation” I den kliniska vardagen ser man ofta slående variationer i handläggningsrutiner mellan läkare och vårdcentraler utan att detta kan förklaras av skillnader i sjuklighet hos patienterna. Dessa oförklarade skillnader benämns ”practice variation” och beror på lokalt förankrade rutiner ofta etablerade sedan länge. De är sällan vetenskapligt underbyggda uBackground and Aims: Differences in the clinical care of patients have been explained through the concept of practice variation, that is, the occurrence of established local medical procedures that varies between geographic areas. The primary measures introduced to eliminate undesirable differences in medical care are the introduction of medical guidelines and economical incentives that rewards th

Search for a heavy Standard Model Higgs boson in the channel H -> ZZ -> l(+)l(-) q(q)over-bar using the ATLAS detector

A search for a heavy Standard Model Higgs boson decaying via H -> ZZ -> l(+)l(-)q (q) over bar, where l = e, mu, is presented. The search is performed using a data set of pp collisions at root s = 7 TeV, corresponding to an integrated luminosity of 1.04 fb(-1) collected in 2011 by the ATLAS detector at the CERN LHC collider. No significant excess of events above the estimated background is found.

Utformning av utrymningsplats

An investigation regarding the design of a safe refuge area and more specifically the means for communication from the safe refuge areawas performed. Three types of communication techniques were tested using a survey and using experiments in a virtual reality environment; a signal lamp in combination with a push button system, a text display system and finally a voice communication system. Accordi

Professional Norms Guiding School Principals’ Pedagogical Leadership

PurposeThe purpose of this paper is to identify and analyze the professional norms surrounding school development, with a special emphasis on school principals’ pedagogical leadership.Design/methodology/approachA norm perspective is used to identify possible links between legal norms, professional norms, and actions. The findings are based on answers given by 974 school principals in a web-based q

Efficient Software Development Through Agile Methods

Context: Distributed teams characterize Global Software Engineering (GSE). GSE stakeholders are from different cultures, geographic places and potentially time zones. These conditions have significant consequences on communication, coordination and control of software projects. Given these constraints, distributed teams need to highly rely on each other. Trust is the glue that holds them together

Chemical abundances of 11 bulge stars from high-resolution, near-IR spectra

Context. It is debated whether the Milky Way bulge has characteristics more similar to those of a classical bulge than those of a pseudobulge. Detailed abundance studies of bulge stars are important when investigating the origin, history, and classification of the bulge. These studies provide constraints on the star-formation history, initial mass function, and differences between stellar populati
