The Formation and Breakdown of Passive Film on Ni Alloys : in situ synchrotron studies

Corrosion results in huge annual costs and a large environmental footprint. The corrosion rate of some alloys can be made negligible by the presence of a spontaneously forming oxide film on the surface, a so-called passive film. Famous examples of alloys exhibiting passivity are stainless steels. However, in some demanding applications, stainless steel does not provide significant corrosion resist

The negative association between serum free testosterone and leptin is dependent on insulin-like growth factor-binding protein 1 in healthy young and middle-aged men

OBJECTIVE: Previous studies have shown that serum levels of testosterone correlate negatively with leptin and positively with insulin-like growth factor binding protein 1 (IGFBP-1). The present study examined whether these associations are linked.DESIGN AND PATIENTS: The association between serum levels of IGFBP-1, free testosterone and insulin on one hand and leptin on the other hand were investi

Large-scale agile transformation in a manufacturing company : a knowledge-based view

Agile has been touted as a concept to deal with and succeed in the fast-paced environment in which companies operate today. Based on this concept, practitioners have created frameworks and practices that have proven to bring benefits in software development. Looking to extend these benefits beyond software development, companies are launching large-scale agile transformation initiatives, however,

Single-cell BCR and transcriptome analysis after influenza infection reveals spatiotemporal dynamics of antigen-specific B cells

B cell responses are critical for antiviral immunity. However, a comprehensive picture of antigen-specific B cell differentiation, clonal proliferation, and dynamics in different organs after infection is lacking. Here, by combining single-cell RNA and B cell receptor (BCR) sequencing of antigen-specific cells in lymph nodes, spleen, and lungs after influenza infection in mice, we identify several

Pitfalls in soft tissue cytopathology

Fine needle aspiration biopsy (FNAB) is a diagnostic modality for the evaluation of suspicious soft tissue masses. Despite its reasonable sensitivity, specificity and positive predictive value in differentiating benign from malignant neoplasms, the exact subtyping of the primary soft tissue tumours can be challenging. Certain tumours constitute “pitfalls” and add to the diagnostic challenge. This

Search for resonant and non-resonant Higgs boson pair production in the bb¯ τ+τ− decay channel using 13 TeV pp collision data from the ATLAS detector

A search for Higgs boson pair production in events with two b-jets and two τ-leptons is presented, using a proton–proton collision dataset with an integrated luminosity of 139 fb −1 collected at s = 13 TeV by the ATLAS experiment at the LHC. Higgs boson pairs produced non-resonantly or in the decay of a narrow scalar resonance in the mass range from 251 to 1600 GeV are targeted. Events in which at

Production of KS0 , Λ (Λ ¯), Ξ±, and Ω± in jets and in the underlying event in pp and p–Pb collisions

The production of strange hadrons (KS0 , Λ, Ξ±, and Ω±), baryon-to-meson ratios (Λ/ KS0 , Ξ/ KS0 , and Ω/ KS0), and baryon-to-baryon ratios (Ξ/Λ, Ω/Λ, and Ω/Ξ) associated with jets and the underlying event were measured as a function of transverse momentum (p T) in pp collisions at s = 13 TeV and p Pb collisions at sNN = 5.02 TeV with the ALICE detector at the LHC. The inclusive production of the

Rethinking Gender in Orthodox Christianity

What is the role of gender in Eastern Christianity? In this volume, Orthodox experts of different disciplines and cultural backgrounds tackle this complex question. They engage critically with gender issues within their own tradition. Rather than simply accepting pervasive assumptions and practices, the authors challenge readers to reconsider historically or theologically justified views by offeriWhat is the role of gender in Eastern Christianity?

Peyer's patch T H17 cells are dispensable for gut IgA responses to oral immunization.

T helper 17 (T H17) cells located at the Peyer's patch (PP) inductive site and at the lamina propria effector site of the intestinal immune system are responsive to both pathogenic and commensal bacteria. Their plasticity to convert into follicular helper T (T FH) cells has been proposed to be central to gut immunoglobulin A (IgA) responses. Here, we used an IL-17A fate reporter mouse and an MHC-I

Research governance and the dynamics of science : A framework for the study of governance effects on research fields

This article offers a framework for the study of research governance effects on scientific fields framed by notions of research quality and the epistemic, organizational, and career choices they entail. The framework interprets the contested idea of 'quality' as an interplay involving notion origins, quality attributes, and contextual sites. We mobilize the origin and site components, to frame org

Automated Design of Self-Adaptive Software with Control-Theoretical Formal Guarantees

Self-adaptation enables software to execute successfully in dynamic, unpredictable, and uncertain environments. However, most of the current approaches lack formal guarantees on the effectiveness and dependability of the adaptation mechanisms, limiting their applicability in practice. Control theory established a broad set of mathematically grounded techniques for the control of dynamic systems fo

Long-term outcomes and prognostic factors for survival of patients with ANCA-associated vasculitis

Background: Despite newer treatments with immunosuppressive agents, there still exists a considerable morbidity and mortality risk among patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Since 1994 the European Vasculitis Society (EUVAS) has aimed for an improved outcome for patients with AAV, conducting several prospective randomized controlled trials (RCTs).

Increased cesarean section rate and premature birth according to modified WHO maternal cardiovascular risk in pregnant women with congenital heart disease

BackgroundDuring pregnancy and delivery, hemodynamics are altered and complex congenital heart disease has been associated with adverse maternal and neonatal outcomes. We sought to investigate pregnancy outcome and complications in relation to complexity of heart condition.Materials and methodsWe studied women with ACHD discussed at multidisciplinary conferences at Lund University Hospital March 2

Faktorer som påverkar traumateamets omhändertagande av patienter vid nivå-1 trauma

Bakgrund: Trauma orsakar livshotande skador och står för nästan åtta procent av alla dödsfall i världen. Det initiala omhändertagandet av traumapatienter ställer krav på att snabbt identifiera, prioritera och behandla befintliga skador. Ett välfungerande traumateam resulterar i en snabbare handläggning vilket förbättrar patientens chanser till överlevnad och minskar risken för komplikationer och f
