Partially premixed combustion with low octane fuel aims to reduce NOx and soot emission simultaneously without fuel consumption penalty. Cylinder pressure based combustion phase control is an essential technology for partially premixed combustion. A novel closed-loop combustion phase control strategy for multiple combustion modes is proposed in the current study. The combustion modes are classifie
In this paper, a novel membrane reactor (MR) for methanol steam reforming is modeled to produce fuel cell grade hydrogen, which can be used as the inlet fuel for a later developed 500-W horizon polymer electrolyte fuel cell (PEFC) stack. The backpropagation (BP) neural network algorithm is employed to develop the mapping relation model between the MR's prime operational parameters and fuel cell ou
Social desirability may cause spurious relations in self-rating measures. The present study sought to disentangle socially desirable responding and content in the relation between measures of personality traits and well-being. Social desirability was operationalized as the evaluative factor (the tendency to react to evaluative content in questionnaire items). We collected self- and peer-ratings of
Human embryonic stem cells (hESC) and induced pluripotent stem cells (iPSC) provide new prospects for studying human neurodevelopment and modeling neurological disease. In particular, iPSC-derived neural cells permit a direct comparison of disease-relevant molecular pathways in neurons and glia derived from patients and healthy individuals. A prerequisite for such comparative studies are robust pr
BACKGROUND: Axillary staging via sentinel lymph node biopsy (SLNB) is performed for clinically node-negative (N0) breast cancer patients. The Skåne University Hospital (SUS) nomogram was developed to assess the possibility of omitting SLNB for patients with a low risk of nodal metastasis. Area under the receiver operating characteristic curve (AUC) was 0.74. The aim was to validate the SUS nomogra
INTRODUCTION: There is limited knowledge on how the SARS-CoV-2 affects pregnancy outcomes. Studies investigating the impact of COVID-19 in early pregnancy are scarce and information on long-term follow-up is lacking.The purpose of this project is to study the impact of COVID-19 on pregnancy outcomes and long-term maternal and child health by: (1) establishing a database and biobank from pregnant w
Background: Patients presenting with synchronous colorectal liver metastases are increasinglybeing considered for a curative treatment, and the liver-first approach is gaining popularity in thiscontext. However, little is known about the completion rates of the liver-first approach and itseffects on survival.Methods:A systematic review and meta-analysis of liver-first strategy for colorectal liver
Strategic University-Industry Collaborations (UICs) are vital for innovation, yet evaluating their multifaceted outcomes presents a significant challenge. This thesis addresses this gap by investigating performance measurement in UICs through an in-depth case study of the long-standing strategic partnership between Tetra Pak and Lund University. By employing a qualitative methodology, incorporatin
Geographical peripheries have long faced marginalization and degradation, enhanced by global trends such as urbanisation. Recently, their revitalization has gained urgency within sustainability discourse, seen as key to achieving global sustainable development. Yet, interventions often focus narrowly on economic recovery, overlooking the social dimension, particularly social cohesion, which is ess
Soil ecosystems are under pressure from a variety of anthropogenic drivers. Yet, we know surprisingly little about the soil biota, which is believed to be the basis of healthy soils. This thesis explores how Danish agricultural advisors work with soil biota to ensure sustainable soil management.Through qualitative interviews, practices, and challenges in caring for soil biota are revealed, uncover
Water for Injection (WFI) is a critical utility in pharmaceutical manufacturing, traditionally produced through an energy-intensive distillation process. This thesis investigates the feasibility of a more sustainable alternative, ambient WFI production using membrane-based purification technologies combined with ozonation in the storage and distribution loop. Conducted in collaboration with AstraZ
This paper analysed the returns on delta-neutral straddles around macroeconomic announcements. The results for straddles on all macroeconomic events were negative returns across all weighting methods and across the majority of holding periods. Furthermore, the returns for individual macroeconomic data announcements were negative, except for money supply and employment data which showed inconclusiv
This thesis analyses how welfare, entitlement and welfare subjects are discursively constructed in the policy process surrounding the proposed qualification requirements for social insurance benefits and financial assistance, as part of the Swedish social benefit reform, ‘bidragsreformen’. Drawing on Norman Fairclough’s three-dimensional model of discourse analysis, the study examines the governme
Background: Ventricular fibrillation (VF) during acute ischemia is linked to increased dispersion of ventricular repolarization (DOR), which is considered a robust marker of arrhythmic susceptibility. In previous works, we showed that a time-warping-based index quantifying morphological changes from the T-wave peak to the T-wave end over a PCA transform lead, dPCAw,Tpe, outperformed the T-peak-to-
The exponential rise in atmospheric CO₂ driven by human activities is accelerating climate change and causing ocean acidification (OA). While the effects of elevated CO₂ on a wide range of marine species have been well documented, the implications of OA for bivalve aquaculture have received comparatively little attention. Using a multi-level meta-analytical approach, we evaluated the impacts of tw
The laminar burning velocity (SL) of methane (CH4), the primary constituent of natural gas, is a key combustion property essential for validating combustion kinetic models. The present study focuses on the CH4 SL at the very rich side of flames, where the available experimental data are scarce with highly dispersed measurement conditions, and data projection was carried out to overcome the difficu
Daylight is crucial for the well-being of individuals in indoor environments, providing numerous physiological and psychological benefits. Achieving satisfactory daylight levels can be particularly challenging during adaptive reuse of existing buildings for new purposes. This study determined the feasibility of adapting an office for residential use by assessing interior daylight availability and
The emergence of large language models (LLMs) has made it easier than ever to create chatbots capable of generating human-like responses to user inputs. Moreover, improvements in text-to-speech and speech-to-text make it possible to converse with these systems, not just in text but also through speech. These improvements have led to an increase in chatbot applications across various contexts, such
The Light Dark Matter eXperiment (LDMX) is proposed to employ a thin tungsten target and a multi-GeV electron beam to carry out a missing momentum search for the production of dark matter candidate particles. We study the sensitivity for a complementary missing-energy-based search using the LDMX Electromagnetic Calorimeter as an active target with a focus on early running. In this context, we cons
