To clarify the misfire mechanism is important for stabilizing combustion in partially premixed combustion (PPC) under low load. Fuel-tracer planar laser-induced fluorescence (PLIF), formaldehyde PLIF, flame and OH* natural luminosity imaging were utilized to qualify the local equivalence ratio, low-temperature reaction and the high-temperature flame features in an optical engine. Results show that
Background: The ability for women to self-collect human papillomavirus (HPV) samples can potentially reduce the risk of cervical cancer and increase screening coverage. Objectives: To assess the willingness to HPV self-sampling for cervical cancer screening and its predictors among women attending outpatient clinics in Arusha region, northern Tanzania. Methods: A hospital-based cross-sectional stu
We present an analysis of atmospheric transport impact on estimating CO2 fluxes using two atmospheric inversion systems (CarboScope-Regional (CSR) and Lund University Modular Inversion Algorithm (LUMIA)) over Europe in 2018. The main focus of this study is to quantify the dominant drivers of spread amid CO2 estimates derived from atmospheric tracer inversions. The Lagrangian transport models STILT
Aviation currently contributes about 3% of the world’s CO2 emissions, 5% of the global warming, and 35% of the trade. Reducing the emissions and the global warming from aviation is thus essential. Many approaches to achieve this goal are underway, including H2, fuel cells, and batteries, but also by replacing the fossil jet fuel with sustainable jet fuel from non-fossil feedstocks. This involves m
I Sverige överlever idag uppemot 80% av de barnen som är födda extremt för tidigt (födda innan graviditetsvecka 28). Dock medföljer en hög sjuklighet, där uppemot 20% av barnen utvecklar olika sjukdomstillstånd såsom blödning i hjärnas hålrum, även kallat intra-ventrikulär hjärnblödning (IVH). Dessutom löper de extremt för tidigt födda barnen en ökad risk att utveckla en intellektuell och neurologExtremely preterm infants (i.e., born below 28 gestational weeks), are at high risk of developing brain morbidities including intraventricular hemorrhage (IVH) and neurodevelopmental impairment. Despite over 50 years of research, there is currently no effective therapy available for preventing IVH. Insulin-like growth factor 1 (IGF-1) plays a pivotal role in perinatal development. Extremely preter
This thesis concerns the experimental study of mixing and flow characteristic in turbulent circular impinging jets without and with jet orifice manipulators (i.e. passive-fixed perturbations atthe nozzle exit), without and with swirl. The goal of the studies is to understand the basic mechanisms that control the mixing processes in turbulent impinging jets. The applications of such mixing processe
National greenhouse gas inventories (GHGIs) are submitted annually to the United Nations Framework Convention on Climate Change (UNFCCC). They are estimated in compliance with Intergovernmental Panel on Climate Change (IPCC) methodological guidance using activity data, emission factors and facility-level measurements. For some sources, the outputs from these calculations are very uncertain. Invers
In anonymous online text-based counselling provided by social services, counsellors face specific communicative and professional challenges. One of the challenges is a higher risk of misunderstanding in textual encounters due to the lack of non-verbal clues and conversation participants’ anonymity (Bambling et al. 2008; Dowling & Rickwood 2014; Fukkink & Hermanns 2009). Chat counsellors ne
While grandiose narcissism is well-studied, vulnerable narcissism remains largely unexplored in the workplace context. Our study aimed to compare grandiose and vulnerable narcissism among managers and people from the general population. Within the managerial sample, our objective was to examine how these traits diverge concerning core personality traits and socially desirable responses. Furthermor
Background: Acute mesenteric ischaemia (AMI) is a life-threatening disease where early diagnosis is critical to avoid morbidity and mortality from extensive irreversible bowel necrosis. Appropriate prediction of presence of bowel necrosis is currently not available but would help to choose the optimal method of treatment. The study aims to identify combinations of biomarkers that can reliably iden
Eclipsing binaries are important benchmark objects to test and calibrate stellar structure and evolution models. This is especially true for binaries with a fully convective M-dwarf component for which direct measurements of these stars' masses and radii are difficult using other techniques. Within the potential of M-dwarfs to be exoplanet host stars, the accuracy of theoretical predictions of the
Predicting an uncertain future with uncertain knowledge is a challenge. The success of efforts to preserve biodiversity, to maintain biosecurity and to reduce a negative impact from climate change, depend on scientifically based predictions of future events. The ongoing introduction of non-indigenous species threatens ecological systems for which empirical data is sparse and scientific knowledge i
This paper presents a development of the use of multi-axial ultrasonic data for the quantification of extrinsic, crack or grain-contact induced elastic anisotropy in core samples with application to a UKCS oil field. An approach for inversion of multi-axial velocity measurements is presented, which extends the previous work by Sayers (2002) for the determination of second- and fourth-order crack d
In mass spectrometry-based shotgun proteomics, protein identifications are usually the desired result. However, most of the analytical methods are based on the identification of reliable peptides and not the direct identification of intact proteins. Thus, assembling peptides identified from tandem mass spectra into a list of proteins, referred to as protein inference, is a critical step in proteom
