Lean blowout (LBO) is one of the major instability problems of premixed combustion. LBO equivalence ratio is a function of inlet temperature and pressure, mass flow or aerodynamic loading, and fuel composition. All these, except the last, vary during startup and with load. Developing gas turbine combustors capable of operating within wider range of fuel compositions requires extensive knowledge ab

A comparative experimental investigation has been performed, comparing the emissions from a synthetic jet fuel and from Jet AI. In the investigation, the unburned hydrocarbons were analyzed chemically and the regulated emissions of NOX, CO and HC were measured. All combustion tests were performed under elevated pressures in a gas turbine combustor rig. A Swedish company, Oroboros AB, has developed

Artikeln behandlar det museala arbetet inom Kongl. Museum från 1790-talet till och med 1850-talet, med omgestaltade rum, förvärv av samlingar, konservatorernas arbete och Konstakademiens utbildning av konstnärer. Under denna period växer museiprofessionen fram, vilket utgör förutsättningen för det nya museet på Blasieholmen på 1860-talet.

Results from a search for supersymmetry in events with four or more charged leptons (electrons, muons and taus) are presented. The analysis uses a data sample corresponding to 36.1 fb-1 of proton-proton collisions delivered by the Large Hadron Collider at s=13 TeV and recorded by the ATLAS detector. Four-lepton signal regions with up to two hadronically decaying taus are designed to target a range

Abstract OBJECTIVE To assess the role of four biomarkers of neuroendocrine activation and endothelial dysfunction in the longitudinal prediction of fragility fractures. METHODS We analysed a population-based prospective cohort of 5415 community-dwelling individuals (mean age, 68.9±6.2 years) enrolled in the Malmö Preventive Project followed during 8.1±2.9 years, and investigated the longitudinal Objective To assess the role of four biomarkers of neuroendocrine activation and endothelial dysfunction in the longitudinal prediction of fragility fractures.

Behandlar ett förbisett arkivmatrial som visar vilken roll Oscar (I) och Josephina som kronprinspar i Sverige spelade i de arkitektoniska och konstnärliga förbindelserna mellan Stockholm och München från 1820-talet till och med 1840-talet, däribland kontakterna med Leo von Klenze och Ludwig Schwanthaler.

Artikeln behandlar ett specifikt motiv i den franska impressionismen från 1860-talet: den bortvända kvinnogestalten, ofta i promenaddräkt. Här berörs relationen till carte-de-visite-fotografiets helfiguriga promenadmotiv och en äldre figurkomposition från Watteau.

Software developers are gaining increasing influence within every company they work for and work with. Engaging at C-level is no longer sufficient: the software developer is now a powerful force in decision-making.This book is intended to be the “textbook” for those working - or starting - in developer marketing. It will teach you how to engage with developers to build a two-way relationship that

Objetos como los artefactos no interactúan con los usuarios, no significan por sí mismos y no comunican. Estas premisas tienen implicaciones en la forma en que se asumen las actuales tendencias del diseño que dan por sentado, sin mayor atención, las interacciones entre el artefacto y los usuarios, olvidando que dichas interacciones fueron formuladas en un contexto cibernético y no en un contexto s

Purpose: The aim of this study was to investigate people’s experiences of living with dysphagia after stroke, and their experiences of dysphagia management. Methods: The study design was qualitative, and an open-ended approach to data collection was used, with follow-up probing questions to gain more information as needed. Personal interviews were conducted with five persons who had persisting mod

Electric Road Systems (ERS) have emerged as an alternative to deal with the main drawbacks that battery electric vehicles present (i.e., higher cost, short driving range, long charging times, etc.). This paper analyses the societal cost of electrifying all road transport in Denmark under four different scenarios. The first scenario considered in this study is based on today's approach of having el

This chapter reviews the development of strategic environmental assessment (SEA) systems in the Eastern Europe, Caucasus and Central Asia (EECCA) countries that were once part of the former Soviet Union. Although diverse, these countries share a number of similar structures that have in?uenced the evolution of their SEA systems. Speci?cally, SEA in the EECCA region is based on State Environmental

Background: Familial confounding is confounding due to genetics or environmental exposures shared by family members. We aimed to study whether familial confounding explains the association between body mass index (BMI) and severe hip osteoarthritis (OA). Methods: We linked data from the Norwegian Arthroplasty Registry with the Norwegian Twin Registry on the National ID-number in 2014, generating a

ExtendJ (formerly JastAddJ) is an extensible Java compiler, supporting full Java source-to-bytecode compilation. ExtendJ enables researchers and developers to easily build powerful language extensions, custom static analyses, and other tools for Java. ExtendJ is built with Reference Attribute Grammars and Aspect Oriented Programming, enabling easy extension development.

A 59-year-old female secretary was referred for evaluation and treatment of a non-healing painful ulcer on the medial aspect of her right lower leg. The ulcer had been recurrent almost every year for the past 9 years, often healing during the winter season. She had since early childhood been overweight (currently 87 kg, 170 cm, body mass index 30) and had difficulty in using compression stocking.

A search for the decay of the Standard Model Higgs boson into a bb pair when produced in association with a W or Z boson is performed with the ATLAS detector. The analysed data, corresponding to an integrated luminosity of 36.1 fb-1, were collected in proton-proton collisions in Run 2 of the Large Hadron Collider at a centre-of-mass energy of 13TeV. Final states containing zero, one and two charge

High body mass index (BMI) is associated with development of hematological malignancies (HMs). However, although BMI is a well-established measurement of excess weight, it does not fully reflect body composition and can sometimes misclassify individuals. This study aimed at investigating what body composition measurements had highest association with development of HM. Body composition measurement

This paper describes the implementation and performance of a particle flow algorithm applied to 20.2 fb- 1 of ATLAS data from 8 TeV proton–proton collisions in Run 1 of the LHC. The algorithm removes calorimeter energy deposits due to charged hadrons from consideration during jet reconstruction, instead using measurements of their momenta from the inner tracker. This improves the accuracy of the c

The distribution of exoplanet masses is not primordial. After the initial stage of planet formation, gravitational interactions between planets can lead to the physical collision of two planets, or the ejection of one or more planets from the system. When this occurs, the remaining planets are typically left in more eccentric orbits. In this report we demonstrate how the present-day eccentricities
