Gas chromatographic analyses of muramic acid, diaminopimelic acid and D-alaline, which are specific components of the bacterial cell wall, have been performed using electron capture or selected ion monitoring detection. Intact cells or peptidogylycan preparations were hydrolyzed in HCl and DCl. After purification by cation exchange chromatography, followed by conversion to the N-heptafluobutyrliso
A search for flavour-changing neutral current (FCNC) events via the coupling of a top quark, a photon, and an up or charm quark is presented using 81 fb−1 of proton–proton collision data taken at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC. Events with a photon, an electron or muon, a b-tagged jet, and missing transverse momentum are selected. A neural network based on kin
Purpose: The aim of this study was to translate the health-related quality-of-life questionnaire EORTC QLQ-LMC21 into Swedish and to test its clinical and psychometric reliability and validity in patients with liver metastases from colorectal cancer (CRC) undergoing surgical treatment. Methods: The Swedish versions of the EORTC QLQ-C30 and EORTC QLQ-LMC21 were administered to 250 patients with liv
We present the artillery of a well-preserved late medieval Danish-Norwegian carvel warship, Gribshunden. Probably built in the Netherlands in 1484, the ship served King Hans until sinking in June 1495. Of its original 50 or more guns, elements of 11 have been recovered and digitally recreated, and more remain on the wreck. Investigation of this site provides insights into the development of shipboWe present the artillery of a well-preserved late medieval Danish-Norwegian carvel warship, Gribshunden.

Functionalized computed tomography (CT) in combination with labelled cells is virtually non-existent due to the limited sensitivity of X-ray-absorption-based imaging, but would be highly desirable to realise cell tracking studies in entire organisms. In this study we applied in-line free propagation X-ray phase-contrast CT (XPCT) in an allergic asthma mouse model to assess structural changes as we
Human-bacterial interactions play a crucial role in several essential aspects of life. Here, we describe how a secreted protein from the skin commensal Cutibacterium acnes, RoxP, functions as a sacrificial redox effector molecule that facilitates beneficial interactions with its human host by counteracting oxidative stress and reducing stress-induced inflammation. Using a combination of structural
A search is presented for direct pair production of the stop, the supersymmetric partner of the top quark, in a decay through an Formula Presented-parity violating coupling to a charged lepton and a Formula Presented-quark. The dataset corresponds to an integrated luminosity of Formula Presented of proton-proton collisions at a center-of-mass energy of Formula Presented collected between 2015 and
A general formulation for the distribution problem is presented, which is applicable to frequency distributions of subgrid-scale variables and hydrometeor size distributions, as well as to probability distributions characterizing data uncertainties. The general formulation is presented based upon two well-known basic principles: the maximum-entropy principle and the Liouville equation. The maximum
Background: The purpose of this study was to evaluate if a positron emission tomography (PET) scan, 6 weeks post radiotherapy (RT), adequately selects patients in whom a neck node dissection can be omitted. Primary endpoints were isolated neck recurrences and overall survival (OS). Methods: 105 patients, mainly with oropharyngeal human papilloma virus (HPV) positive tumors, with a positive PET sca
Health related quality of life (HRQoL) was assessed in the randomised, prospective ARTSCAN study comparing conventional radiotherapy (CF) with accelerated radiotherapy (AF) for head and neck cancer.
On-site hydrogen gas production from hydrogen-rich liquids offers a clean alternative to fossil fuels for combustion that is readily implemented in existing energy infrastructure. A heterogenized (POCOP)-Ir pincer catalyst can be operated at higher temperatures for higher turnover frequency, but the reaction pathway of the reported complex has not been well understood. Here, we report intermediary
Natural gas/diesel dual-fuel combustion is a novel technique that offers high thermal efficiency and reduced emissions without requiring extensive hardware changes or complex aftertreatment systems. Previous study conducted on the same setup has shown that increasing the diesel mass split ratio (SR) between two injections and advancing the start of first injection (SOI1) improved NOx, HC emissions
Background Low competence levels among nursing staff have been associated with lower quality of elderly care. However, interventions aimed at improving nursing staff competence have not always been evaluated for their possible impact on the quality of elderly care. An educational intervention in the form of a workplace “toolbox” was shown to have positive effects on nursing staff competence and wo
A search for new phenomena has been performed in final states with at least one isolated high-momentum photon, jets and missing transverse momentum in proton–proton collisions at a centre-of-mass energy of s = 13 TeV. The data, collected by the ATLAS experiment at the CERN LHC, correspond to an integrated luminosity of 139 fb−1. The experimental results are interpreted in a supersymmetric model in
The Usushwana Complex of the south-eastern Kaapvaal Craton (South Africa and Swaziland), intrudes the ca. 3.6-3.1 Ga basement of the craton, as well as the Mesoarchaean volcanic and sedimentary cover succession of the Pongola Supergroup. New high-precision U-Pb dating of gabbros belonging to the Piet Retief Suite of the Usushwana Complex yield ages of 2989 +/- 1 Ma, 2990 +/- 2 Ma and 2978 +/- 2 Ma
Although documented from Estonia, Latvia, Sweden, eastern North America, and China, the Middle Ordovician (Darriwilian) positive delta C-13 excursion known as the MDICE has previously not been recognized with certainty in South America. The most promising region in South America for detailed Middle Ordovician carbon isotope research is the Precordillera of western Argentina, where there are many e
Supply chains are no longer to be regarded as linear constructs with definite starting and ending points, but as systems, or wholes that are to be customer driven rather than product driven. But however easy it sounds in theory industries are struggling to re-invent or re-comprehend existing business models. This paper aims to describe and identify organizational challenges to re-defining the supp
Hereditary defects of the von Willebrand factor (VWF) gene cause von Willebrand's disease (VWD) which shows great variability dependent on the nature and location of the mutation. We here describe the characteristics of a substitution of methionine for threonine 1156 in the D3 domain of the VWF, i.e. the domain involved in the intracellular multimerization of pro-VWF dimers. A VWD patient withseve
Using a recently introduced multiplex polymerase chain reaction and restriction fragment length polymorphism ABO genotype screening method we have found an anomalous ABO genotype (A2O1variant) not correlating with the serological phenotype (blood group O). The blood group was confirmed by absorption/elution and detection of blood group substances in saliva. Sequencing of exons 6 and 7 in the ABO g
A search for direct pair production of supersymmetric top squarks ((t) over tilde (1)) is presented, assuming the (t) over tilde (1) decays into a top quark and the lightest supersymmetric particle, (chi) over tilde (0)(1), and that both top quarks decay to purely hadronic final states. A total of 16 (4) events are observed compared to a predicted standard model background of 13.5(-3.6)(+3.7) (4.4
