European CH4 emissions are estimated for the period 2001-2006 using a four-dimensional variational (4DVAR) inverse modeling system, based on the atmospheric zoom model TM5. Continuous observations are used from various European monitoring stations, complemented by European and global flask samples from the NOAA/ESRL network. The available observations mainly provide information on the emissions fr
The commissioning phase is the last phase of a construction project when all subsystems come together to be tested as a whole, working as a single entity. This phase is often the most crucial and time-sensitive part of the project as the construction occupies space in the factory and inflicts down¬time in processes without adding value. Faults found in this phase can be time-consuming to correct a
Possibilities to simulate control systems can be very useful. During the development of a control system, simulations can verify that the implemented algorithms work as expected. Smaller parts of the implementation can be tested before they are put together to a complete control system. In an existing plant simulation can be used for optimization of the control system and control parameters ca
The growing use of wind energy as major energy source, has led to the construction of large wind farms. The control of such wind farms is typically separated into control at wind turbine level and at wind farm level. The wind farm controller assures that the wind farm produces the demanded amount of power, by providing set-points for the turbines in the farm. The local turbine control assures that
This thesis conducts an in-depth investigation of the conformal two Higgs doublet model (C2HDM) in its most general form, integrating complex couplings λ5, λ6, λ7 and a CPviolating phase e−iδ. This setup enables a detailed exploration of $\mathcal{CP}$-violation and its impact on electroweak phase transitions (EWPT) and gravitational wave (GW) signatures. Using the Higgs basis simplifies tree-le
Saving peak powers in the heating systems have been in focus for some years now. Sweden has more and more cooling systems with an increase in cooling also in residential buildings. The cooling power is much more expensive than the heating power and the cost of cooling is largely driven by installed power. Therefore, there is a relative advantage of reducing the cooling power instead of heating pow
This study examines how consumers make sense of AI-generated fashion advertising and how this shapes brand-consumer relationships. Using a qualitative and interpretive approach, this study draws on twelve semi-structured interviews with students at Lund University School of Economics and Management (LUSEM). The analysis is informed by Consumer–Brand Relationship theory (Fournier, 1998), Social Pre
This study examines whether the take-back and resale programmes of leading global fast-fashion retailers deliver substantive circular change or instead represent means-ends decoupling. Drawing on means-ends decoupling and organisational legitimacy theory, it analyses the corporate sustainability reports of H&M Group, Fast Retailing, and Inditex across five consecutive fiscal years (FY2020–FY20
Positron emission tomography (PET) with (18)F-FDG is a valuable tool for staging, planning treatment, and evaluating the treatment response for many different types of tumours. The correct volume estimation is of utmost importance in these situations. To date, the most common types of phantoms used in volume quantification in PET utilize fillable, hollow spheres placed in a circular or elliptical
Purpose: Several tumor markers have recently been applied for prostate cancer screening. We analyze the effectiveness of prostate specific antigen (PSA), age specific PSA, PSA velocity, volume adjusted PSA densities, change in PSA level following antibacterial therapy, free-to-total PSA ratio, alpha1-antichymotrypsin bound PSA, alpha2-macroglobulin bound PSA, alpha1-protease inhibitor bound PSA an
Background: Functional polymorphisms of the solute carrier family 22, member 4 (SLC22A4), runt related transcription factor 1 (RUNX1) and small ubiquitin- like modifier 4 (SUMO4) genes have been shown to be associated with several autoimmune diseases. Objective: To test the possible role of these variants in susceptibility to or severity of systemic lupus erythematosus (SLE), on the basis that com
As the identification process is based on the unique patterns of the users, biometrics technologies are expected to provide highly secure authentication systems. The existing systems using fingerprints or retina patterns are, however, very vulnerable. One's fingerprints are accessible as soon as the person touches a surface, while a high resolution camera easily captures the retina pattern. Thus,
Pelvic fractures may occur together with hip fractures as a result of low energy trauma. It is unclear whether they do require special attention. There are conflicting results in the literature about the prevalence of both concomitant hip and pelvic fractures as well as exclusive pelvic fractures. It has been reported that hip fractures and obturator ring fractures are mutually exclusive. To retro
BACKGROUND: It has previously been shown that propofol in clinically relevant concentrations induces a calcium-dependent conformational change in the cytoskeleton. The aim of this study was to further clarify the effect of propofol on the actin cytoskeleton and to determine if this conformational change is mediated by the interaction between the GABA(A)-receptor and propofol. METHODS: Primary cult
The article outlines the most pressing justice questions in a transition to a fossil fuel-free welfare state in Sweden.
Human mitochondrial dihydroorotate dehydrogenase (the fourth enzyme of pyrimidine de novo synthesis) has been overproduced by means of a recombinant baculovirus that contained the human cDNA fragment for this protein. After virus infection and protein expression in Trichoplusia ni cells (BTI-Tn-5B1-4), the subcellular distribution of the recombinant dihydroorotate dehydrogenase was determined by t
Purpose: The purpose of the study was to investigate if surface guided radiotherapy (SGRT) can decrease setup deviations for tangential and locoregional breast cancer patients compared to conventional laser-based setup (LBS). Materials and Methods: Both tangential (63 patients) and locoregional (76 patients) breast cancer patients were enrolled in this study. For LBS, the patients were positioned
