Ear reconstruction with autologous rib cartilage is performed in stages. Restitution of blood flow between the separate stages is crucial to obtain a good result. Laser Doppler perfusion imaging (LDPI) and local temperature were measured in reconstructed and normal ears in response to indirect heating. Ten persons who had had a unilateral ear reconstruction were included in the study. At a minimum
Greenery is assumed to promote physical activity at school grounds by facilitating open and flexible play situations that engage many children. The role of greenery for school ground activity was investigated at two schools, one of which contained a substantial amount of greenery and the other one little greenery. All in all 197 children from 4th (10-11 years) and 6th grade (12-13 years), were inv
ANCA-associated vasculitis is commonly found in elderly patients, but there are few data concerning outcome and treatment in the highest age groups.
The European Spallation Source (ESS), Lund, Sweden will be a 5MW long-pulse neutron spallation research facility and will enable new opportunities for researchers in the fields of life sciences, energy, environmental technology, cultural heritage and fundamental physics. Neutrons are produced by accelerating a high-energy proton beam into a rotating helium-cooled tungsten target. These neutrons pa
The ATLAS experiment has observed 1995 Z boson candidates in data corresponding to 0.15 nb(-1) of integrated luminosity obtained in the 2011 LHC Pb + Pb run at root s(NN) = 2.76 TeV. The Z bosons are reconstructed via dielectron and dimuon decay channels, with a background contamination of less than 3%. Results from the two channels are consistent and are combined. Within the statistical and syste
Concentrating cells is a frequently performed step in cell biological assays and medical diagnostics. The commonly used centrifuge exhibits limitations when dealing with rare cell events and small sample volumes. Here, we present an acoustophoresis microfluidic chip utilising ultrasound to concentrate particles and cells into a smaller volume. The method is label-free, continuous and independent o
Given the anthropometric differences between men and women and previous evidence of sex-difference in genetic effects, we conducted a genome-wide search for sexually dimorphic associations with height, weight, body mass index, waist circumference, hip circumference, and waist-to-hip-ratio (133,723 individuals) and took forward 348 SNPs into follow-up (additional 137,052 individuals) in a total of
Purpose – The purpose of this paper is to look more closely at the residents’ attitude to individual heat metering and charging systems (IMC) of multi-family dwellings in residential properties, and to evaluate the tenant’s perception of IMC and how it may affect the continued expansion of such systems. Design/methodology/approach – The research in this paper is based on a questionnaire and interv
A search is performed for top-quark pairs (t (t) over bar) produced together with a photon (gamma) with transverse energy greater than 20 GeV using a sample of t (t) over bar candidate events in final states with jets, missing transverse momentum, and one isolated electron or muon. The data set used corresponds to an integrated luminosity of 4.59 fb(-1) of proton-proton collisions at a center-of-m
The potential machinability for Alloy 718 (Inconel 718) is examined in terms of five material characteristics considered to play a key role in the machinability: ductility (elongation to fracture), strain hardening (ultimate tensile strength over yield strength), thermal conductivity, yield strength and abrasiveness (amount of carbides). The material characteristics are simulated with the software
Results of a search for H -> tau tau decays are presented, based on the full set of proton-proton collision data recorded by the ATLAS experiment at the LHC during 2011 and 2012. The data correspond to integrated luminosities of 4.5 fb(-1) and 20.3 fb(-1) at centre-of-mass energies of root s = 7TeV and root s = 8 TeV respectively. All combinations of leptonic (tau -> l nu(nu) over bar with l = e,
Purpose – This paper aims to investigate the strategies used by Swedish citizens to adapt to changing climate variability and extremes. There is an increasing consensus that individual adaptive capacities are critical to successfully adapt to climate change and achieve sustainable development. However, little is known about individual adaptive practices, particularly in developed countries. Design
Interactions between iron (Fe) and arsenic (As) play a vital role in aquatic and terrestrial ecosystems influencing the reactivity and transport of arsenic. A key aspect is the effect of natural organic matter (NOM) on these interactions, and previous investigations have reported the existence of ternary As-Fe-NOM species. In this study, the reactivity of Fe, from a boreal stream water, towards As
The mechanisms for oxygen etching of graphene on Ir(111) are uncovered through a systematic variation of the graphene morphology - ranging from an impermeable graphene layer to graphene nanoflakes - and the application of complementary experimental methods, including scanning tunneling microscopy, X-ray photoelectron spectroscopy, and temperature programmed desorption. Associated with a strong var
This study describes an efficient isolation procedure for the extraction of polar lipids from two strains of bifidobacteria - Bifidobacterium longum and Bifidobacterium angulatum. We first compared the lipid profiles of two strains of bifidobacteria and showed that the strains of the same genus may differ by lipid composition of cell walls. The polar lipids were isolated using the following condit
We argue that our common diseases should not necessarily be taken as a sign of physiological error. Regulatory networks developed by evolutionary forces to support reproductive fitness happen to include disease as a side-effect. For example, inflammatory and autoimmune diseases are secondary to a strong defence against infections. An evolutionary perspective can help us understand why many drugs t
Six different ionomers having various aromatic polymer backbones with pendant 2-sulfobenzoyl side chains were prepared by nucleophilic aromatic substitution reactions of lithium 2,6-difluoro-2′-sulfobenzophenone with 4,4-biphenol, 2,7-dihydroxynaphthalene, 4,4-isopropylidenediphenol, 4,4-dihydroxydiphenyl ether, 4,4′-thiodiphenol, and 4,4′-thiobisbenzenethiol, respectively, to produce four poly(ar
Matrix metalloproteinase-9 (MMP-9) regulates platelet shedding of CD40L in abdominal sepsis. However, the signaling mechanisms controlling sepsis-induced shedding of CD40L from activated platelets remain elusive. Rac1 has been reported to regulate diverse functions in platelets; we hypothesized herein that Rac1 might regulate platelet shedding of CD40L in sepsis. The specific Rac1 inhibitor NSC237
