Two-dimensional numerical simulations of the flow and temperature fields inside the bend (turn) part of a U duct have been performed. Both the standard and low Reynolds number k-epsilon models were used to solve the smooth bend (turn) part and ribbed bend (turn) part, respectively. For the standard k-epsilon model, the wall function approach was used at the near wall region where the log-law was a
The glycosphingolipid (GSL) antigens in the clinically important P1PK and GLOB blood group systems are present on erythrocytes as well as other tissues and are so-called histo-blood group antigens. Blood group antigens of carbohydrate nature are products of enzymes, so-called glycosyltransferases, adding sugars in a step-wise manner to an acceptor substrate. Presence or absence of the P1PK and GLO
In this paper we present a systematic study of the morphology and composition of supported lipid bilayers (SLBs) formed by vesicle fusion using a wide variety of surface sensitive techniques that give information about the lateral as well as vertical structure and bilayer fluidity. SLBs of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC
A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. To get a time-linear scaling, we present an approximation to the collision integral, which offers a good tr
Populärkulturen spelar en viktig roll i att forma föreställningar om romantiska relationer, kärlek och intimitet. Denna uppsats syftar till att undersöka hur filmen “Fifty Shades of Grey” romantiserar makt och kontroll genom sina visuella och narrativa uttryck. Studien ägnar särskild uppmärksamhet åt hur kontroll legitimeras och hur könsroller representeras i relationen mellan de två protagonister
Denna uppsats undersöker det framväxande förhållandet mellan geografiska beteckningar (Geographical Indications, GI) och varumärken inom EU-lagstiftningen, med särskilt fokus på den rättsliga utvecklingen som mynnat ut i förordning 2024/1143. Även om både GI och varumärken utgör immate-riella rättigheter, tjänar de olika syften. Varumärken skyddar främst privata kommersiella intressen och företagsThis thesis explores the evolving relationship between geographical indica-tions (GIs) and trademarks within European Union (EU) law, with a particu-lar focus on the legal developments culminating in Regulation 2024/1143. While both GIs and trademarks are forms of intellectual property, they serve different purposes. Trademarks primarily protect commercial brand identity, while GIs are recognised
Information management is a central part of organizations in today´s society, and critical research is continuously made to assess the reliability of sources. Previous studies have suggested that information with confidential sources tends to be perceived as more credible compared to open sources. The aim of the thesis was to analyze the perceived credibility of information from confidential versu
Metabolism plays a crucial role in an animal’s life as it determines the amount of energy that can be allocated to growth, reproduction, and survival. The strategies an individual adopts to manage its energy budget have direct consequences to its fitness. How an animal allocates its energy will determine whether it can ensure its own survival while having a high reproductive success or neglect one
The advent of new technologies for single-cell RNA sequencing analyses has resulted in the discovery that the myeloid compartment in the tumor microenvironment (TME) is far more complex than previously appreciated, and that intrinsic and extrinsic factors in the TME highly influence the immunosuppressive or active states of these cell types. There is now a need to develop multiplex assays to ident
This study analyzes the return to schooling in 22 countries. More specifically, the effect on earnings of receiving a bachelor’s and a master’s degree is estimated by applying a propensity score matching approach on microdata. Unlike many other techniques, propensity score matching addresses selection bias to a higher extent making the estimates of the treatment effect on the treated more reliable
Avian influenza constitutes a remarkable threat to global health. Interaction between wild and domestic ducks in the natural wetlands has been considered one of the potential risk factors for the rapid spread of the avian influenza virus. Tanguar haor is one of the vital wetlands in Bangladesh, a wintering place of millions of migratory birds. At the same time, native farmers raise their domestic
Korslimmat trä är ett tämligen nytt material, bestående av korslagda lager av brädor. Produkten tillåter nya byggmetoder och kan ses som ett grönare alternativ till stål och betong. Dess uppbyggnad gör det mer robust och mindre beroende av träets varierande egenskaper för olika geometriska dimensioner. Som ett nytt byggnadsmaterial är dess beteende och karaktär inte lika välstuderat. Med trä som iCross-laminated timber is a fairly new material, composed of layers of timber boards cross-placed. The product allows for new construction techniques and can be seen as a more sustainable alternative to steel and concrete. Its structure makes it more robust and less dependent on the variation in properties of wood for different geometrical dimensions. As a new material, the CLT is not well studied
High affinity antibodies of appropriate isotype are crucial for protection against pathogens and are generated within secondary lymphoid organs in structures called germinal centers (GC). Apart from affinity maturation, germinal centers also give rise to memory B cells and plasma cells, but how these fate decisions are regulated and what signals may be delivered by TFH cells is still unclear. Usin
Since 1994 super-resolution microscopes enable us to visualize processes in the nanome- ter regime where bio-molecules work. Consequently, there is a great need for methods analyzing the generated data to transfer the motion of molecules, seen as white dots, into trajectories. Important steps in understanding bio-molecular behavior are first the detection of those and then generating trajectories
This work presents the synthesis and structural characterization of titanate nanoproducts, focusing on the effect induced by the presence of silver ion in different concentrations. The synthesis and chemical analysis using TEM, XRD and EDX were performed at the University of Szeged in Hungary. The XAS analysis was done at the MaxLab synchrotron facility in Lund University, Sweden. From the analysi
An earthshine telescope has been designed and is being fabricated at Lund Observatory in collaboration with the Danish Meteorological Institute. The instrument will measure the albedo of the Earth by observing the Moon in white light and in certain spectral bands. The measurement is based on relative photometry of the dark and bright sides of the Moon, so the optical design of the telescope has be
Våld mot kvinnor är ett av de mest allvarliga brotten mot internationella mänskliga rättigheter i världen. Det bekräftar underordningen av kvinnor, den patriarkatiska normgivningen och den otillräckliga implementationen av mänskliga rättigheter. Det här arbetet utreder vad våld i hemmet består av i Indien och i Sverige. I Indien är detta fokuserat på dowry-våld och i Sverige är ”vanligt” våld i heViolence against women is one of the most serious international human rights breaches in the world. It reaffirms the subordination of women, the patriarchal standard setting and insufficient implementation of human rights. This thesis investigates what domestic violence consists of in India and in Sweden. In India this is focused on dowry violence and in Sweden “ordinary” domestic violence and hon
