Vitiation refers to the condition where the oxygen concentration in the air is reduced due to the mix of dilution gas. The vitiation effects on a premixed methane flame were investigated on a swirl-stabilized gas turbine model combustor under atmospheric pressure. The main purpose is to analyze the combustion stability and CO emission performance in vitiated air and compare the results with the fl
With an increasing population, a growing middle class and increased resource use, our current ways of living and doing business are unsustainable. Next to the implementation of innovative technology, sustainable development based on innovative business models, better understating of customer needs and behavioural change are crucial. This research aims at combining principles from both sustainable
Aims: This study aimed to examine the population-based Skåne Health-care Register (SHR) regarding feasibility for scientific research and also strengths and weaknesses. Methods: To analyse the feasibility of the SHR, we performed a bibliographic search for peer-reviewed articles based on SHR data from 2000 to 2018. To analyse strengths and weaknesses, we used original SHR data about coverage and v
Background: Although reproductive history is recognised to affect the risk of breast cancer, current breast cancer screening guidelines do not consider risk differences by this important factor. As there is a need for an earlier screening in women at increased risk of breast cancer, we provided evidence-based risk-adapted starting age of screening based on different reproductive profiles. Material
Our purpose is to critically discuss the quality of governability and scrutiny of, as well as insight in, enterprises owned by local government. Our analysis is empirically grounded in an in-depth case study of one of Sweden’s 10 largest municipalities. The ambition is to highlight troublesome areas and danger zones when it comes to public owning of corporations. We have consulted diverse types of
High-order harmonic generation is a highly nonlinear, though inherently inefficient, process which can lead to emission of coherent, broadband extreme ultraviolet radiation in the form of attosecond pulses. Attosecond pulses are crucial for experiments investigating photoionization dynamics on the femto- and attosecond timescales. As attosecond research tends towards increasingly complex light-mat
What is nationalism? When did it originate and how did it develop throughout the centuries? What types of nationalism have evolved in different sociopolitical settings and why? By addressing these questions, this entry seeks to address the key issues of the conceptualization of nationalism, followed by an analysis of its development in different structural, cultural, and political contexts. The en
Objective: To determine the level of agreement of disease flare severity (distinguishing severe, moderate, and mild flare and persistent disease activity) in a large paper-patient exercise involving 988 individual cases of systemic lupus erythematosus. Methods: A total of 988 individual lupus case histories were assessed by 3 individual physicians. Complete agreement about the degree of flare (or
Background: The negative impact of maternal smoking during pregnancy on offspring semen quality is well established. Less is known about the impact of paternal smoking. Methods: We estimated differences in semen parameters and testicle size according to paternal smoking in 772 adult sons of women enrolled in the Danish National Birth Cohort when pregnant. Parents’ smoking was reported around gesta
Popular Abstract in Swedish Utforskar äldre och funktionshindrades behov av planeringsinformation i kollektivtrafiken och diskuterar huruvida information kan bidra till tillgängligheten. En omfattande enkätundersökning genomfördes för att validera tidigare genomförda fokusgruppsintervjuer om äldre och funktionshindrades informationsbehov. Resultaten visar att det finns ett behov av information bla
Virtual Reality (VR) has shown great potential in various training applications. In the field of cognitive rehabilitation it has been shown that VR technology can become a useful complement to conventional rehabilitation techniques (e.g. Rizzo et al. (2002), Brown et al. (2002) and Kizony et al. (2002)). An important part of a brain injury patient’s rehabilitation process is practicing instrumenta
This article discusses why films have not been used more than they have as historical sources and argues that films ought to be used more by historians. Principally, historians can use film in three basic ways, all of which give access to information about the period when it was produced. First, films can with caution be used for information about the persons, objects and events depicted in docum
Popular Abstract in Swedish Denna avhandling undersöker hur vi använder visuell kontextinformation i samtal. Alla modeller över språkprocessning och kommunikation är ense om att visuell kontextinformation har en positiv nettoeffekt på förståelse och kommunikation. Trots detta är det inte klart genom vilka mekanismer denna kontextinformation verkar, eller om dessa mekanismer fungerar i situationer This dissertation is about the role of visual context information in communication. All accounts of language processing and communication agree that visual context is beneficial for understanding. Despite this, it is not clear through which mechanisms visual context works and whether these mechanisms also work in communication outside the lab setting. This dissertation aims to provide answers to t
Aims and objectivesTo explore how nurses and managers perceive that evidence‐based sources are obtained to inform relevant nursing interventions.BackgroundImplementation of evidence‐based practice requires a systematic search and evaluation of research, clinical expertise and consideration of the patients’ preferences and values. Much has been written over the past decade about how this should be
The rising trend in the prevalence of obesity has become a major public health concern in many countries during the past decades, partly because being obese is associated with comorbidities and death. The cost of treatment for obesity related diseases has become a heavy burden on the national health care budget in many countries. The treatment options for obesity are mainly weight management thera
Little is known about the lipid composition of cold-adapted dinoflagellates. Here, we investigate Peridinium aciculiferum and Scrippsiella hangoei, two cold-adapted dinoflagellate morphospecies that present significant differences in general morphology, physiology and habitat, but which share identical ribosomal DNA (rDNA) sequences, indicating a recent evolutionary divergence between them. Despit
Asymmetrical flow field-flow fractionation (AsFIFFF) in combination with multi-angle light scattering (MALS) was applied to cationic potato amylopectin (CPAP) to investigate how molar mass, root-mean-square (r.m.s.) radius and shape was influenced by different conditions of jet-cooking. The effect of different jet-cooking temperatures in the range 110 degrees C - 140 degrees C was studied in an ex
Background & Aims: Preterm birth and formula feeding are key risk factors associated with necrotizing enterocolitis (NEC) in infants, but little is known about intestinal conditions that predispose to disease. Thus, structural, functional, and microbiologic indices were used to investigate the etiology of spontaneous NEC development in preterm pigs. Methods : Piglets were delivered by cesarean
As an approach to determining the aetiology of chronic lymphocytic leukaemia (CLL), we searched for a virus expressed in human CLL B-cells by combining high-throughput sequencing and digital subtraction. Pooled B-cell mRNA transcriptomes from five CLL patients and five healthy donors were sequenced with 454 Life Sciences technology. Human reads were excluded by BLAST (Basic Local Alignment Search
Transaction costs (TCs) must be taken into account when assessing the performance of policy instruments that create markets for the diffusion and commercialization of low-carbon technologies (LCTs). However, there are no comprehensive studies on the development and application of transaction cost analysis to LCTs. In this meta-analysis, a wide-ranging evaluation of TCs associated with energy effic
