In this work we investigated the ability of a series of amino acids to act as cloud condensation nuclei using a static thermal gradient diffusion type cloud condensation nucleus counter. Particles of pure dry l-glycine, glycyl-glycine, l-serine, l-methionine, l-glutamic acid, l-aspartic acid, and l-tyrosine were studied as well as internally mixed dry particles containing ammonium sulfate and one
Colossal magnetoresistance (CMR) is associated with the phase transition from a metallic ferromagnetic to insulating paramagnetic phase, which can be controlled by an applied magnetic field. The insulating phase occurs due to trapping of the charge carriers by polaronic lattice distortions, which raise the resistivity. Theories based on local physics predict that the magnitude of the resistivity j
A collection of 38 articles on Archaeology, Historical Arcaheology, Historical Osteology, History and Art History by authors in Sweden, Denmark and Germany, an introduction and also a bibliography as a tribute to retired reader Anders Ödman at the Department of Archaeology and Ancient History, Lund University.
Context. A key science goal of the Gaia-ESO survey (GES) at the VLT is to use the kinematics of low-mass stars in young clusters and star forming regions to probe their dynamical histories and how they populate the field as they become unbound. The clustering of low-mass stars around the massive Wolf-Rayet binary system gamma(2) Velorum was one of the first GES targets. Aims. We empirically determ
Popular Abstract in Swedish Forskningen har visat Den ökade prevalensen av kronisk hjärtsvikt utgör en enorm utmaning för sjukvården. Trots att vi idag har effektiva medicinska behandlingar vid hjärtsvikt och bra läkemedel så är sjukligheten och dödligheten fortfarande betydande. Hjärtsvikt leder till en förändrad kärlreaktivitet generellt i cirkulationen, dock är betydelsen av denna endast känd The increased prevalence of chronic congestive heart failure (HF) is a tremendous challenge for society. In spite of effective medical treatment for acute HF, better pharmacological treatment for specific neurohormonal intervention and better diagnostic tools, e.g. biomarkers of natriuretic peptides, the morbidity and mortality due to this disease are still prominent. HF leads to vascular dysfunct
Sex hormones, particularly the androgens, are important for the growth of the prostate gland and have been implicated in prostate cancer carcinogenesis, yet the determinants of endogenous steroid hormone levels remain poorly understood. Twin studies suggest a heritable component for circulating concentrations of sex hormones, although epidemiologic evidence linking steroid hormone gene variants to
In some recent papers by the first two authors it was shown that for any algebraic crossed product A, where A(0), the subring in the degree zero component of the grading, is a commutative ring, each non-zero two-sided ideal in A has a non-zero intersection with the commutant C-A(A(0)) of A(0) in A. This result has also been generalized to crystalline graded rings; a more general class of graded ri
Background: Transplantation is the treatment of choice for end-stage renal disease; it increases survival and quality of life, while being more cost-effective than dialysis. It is, however, limited by the scarcity of kidneys. The aim of this paper is to investigate the fairness of the priority setting process underpinning Swedish kidney transplantation in reference to the Accountability for Reason
BACKGROUND: The clinical assessment of axillary lymph nodes status and tumor size is important for the management of patients with breast cancer. The first goal of this study was to determine the accuracy of axillary lymph node status in relation to the presence of metastases as revealed by histopathological examination. The second goal was to compare the tumor size as assessed by physical examina
Aims: TCF7L2 variants have been associated with type 2 diabetes, body mass index (BMI), and deficits in proinsulin processing and insulin secretion. Here we sought to test whether these effects were apparent in high-risk individuals and modify treatment responses. Methods: We examined the potential role of the TCF7L2 rs7903146 variant in predicting resistance to weight loss or a lack of improvemen
The initial stages of stress corrosion on an amorphous polymer is investigated. This is done by exposing stressed specimens of polycarbonate to an acetone and water solution. The surface develops two distinct features of degradation that appear on different length scales when subjected to tensile stress. Small pits form on the surface and make it rough. These pits are in the order of micrometers,
The aim of the study was to investigate the prevalence of asthma with or without exercise induced symptoms among elite and elite aspiring swimmers and to compare sport specific exercise provocation with mannitol provocation. METHODS: 101 adolescent swimmers were investigated with mannitol provocation and sport specific exercise challenge test. Mannitol positivity was defined as either direct FEV(1
Background: Clinical signs are a core outcome domain for atopic dermatitis (AD) trials. The current lack of standardization of outcome measures in AD trials hampers evidence-based communication. Objective: We sought to provide evidence-based recommendations for the measurement of clinical signs in AD trials and to inform the Harmonising Outcome Measures for Atopic Dermatitis Initiative. Methods: W
State-of-the-art multiconfiguration Dirac-Hartree-Fock calculations for Te V have been performed and energies, LS-compositions, radiative lifetimes and Lande gJ-factors for 51 odd and even parity states are presented. In addition, predictions on transition rates and oscillator strengths for a multitude of transitions between these states are reported for the first time. To describe the atomic syst
Phylogenetic approaches are indispensable in any comparative molecular study involving multiple species. These approaches are in increasing demand as the amount and availability of DNA sequence information continues to increase exponentially, even for organisms that were previously not extensively studied. Without the sound application of phylogenetic concepts and knowledge, one can be misled when
This Introduction argues for the importance of theology for the study of organization. It also draws the contours of a possible 'theology of organization'. Theology of organization, as we use it here, does not refer to a study of organization that is rooted in faith, nor does it refer to a study of religious practices in organizations. Instead, theology of organization recognizes that the way we t
A method is described for quantification of the beef tenderness marker, calpastatin, in meat samples by amperometric detection. Using a novel bovine recombinant partial calpastatin protein as standard antigen a low detection limit of 0.2 ng/mL was achieved. The influence of the complex matrix was minimised by heat pretreatment and dilution of the samples prior to detection of calpastatin. The rela
