Numerical simulations coupled with laser Doppler velocimetry (LDV) experiments were carried out to investigate a slot jet issued into a cross flow, which is relevant in the film cooling of gas turbine combustors. The film-cooling fluid injection from slots or holes into a cross flow produces highly complicated flow,fields. In this paper, the time-averaged Navier-Stokes equations were solved on a c
In vitro, pancreatic triglyceride lipase requires colipase to restore activity in the presence of inhibitors, like bile acids. Presumably, colipase performs the same function in vivo, but little data supports that notion. Other studies suggest that colipase or its proform, procolipase, may have additional functions in appetite regulation or in fat digestion during the newborn period when pancreati
Time-resolved and spatially resolved measurements of the diffuse reflectance from biological tissue are two well-established techniques for extracting the reduced scattering and absorption coefficients. We have performed a comparison study of the performance of a spatially resolved and a time-resolved instrument at wavelengths 660 and 785 nm and also of an integrating-sphere setup at 550-800 nm. T
Oxygen may modulate cerebrovascular resistance, but its direct influence on human pial arteries is unknown. We have investigated the effects of varying oxygen tension (73, 30 and 8 kPa) in depolarized (potassium) and receptor stimulated (prostaglandin F2 alpha) isolated human pial arteries. Control responses were obtained at an oxygen tension of 30 kPa. Contractions induced by prostaglandin F2 alp
Introduction Alveolar dead space reflects phenomena that render arterial partial pressure of carbon dioxide higher than that of mixed alveolar gas, disturbing carbon dioxide exchange. Right-to-left shunt fraction (Qs/Qt) leads to an alveolar dead space fraction (VdA(S)/VtA; where VtA is alveolar tidal volume). In acute respiratory distress syndrome, ancillary physiological disturbances may include
Ribonucleotide reductase (RNR) is the only source for de novo production of the four deoxyribonucleoside triphosphate (dNTP) building blocks needed for DNA synthesis and repair. It is crucial that these dNTP pools are carefully balanced, since mutation rates increase when dNTP levels are either unbalanced or elevated. RNR is the major player in this homeostasis, and with its four different substra
Background: The utility of conventional prostate-specifi c antigen (PSA) measurements in blood for monitoring rapid responses to treatment for prostate cancer is limited because of its slow elimination rate. Prior studies have shown that free PSA (fPSA), intact PSA (iPSA) and human kallikrein-related peptidase 2 (hK2) are eliminated more rapidly after radical prostatectomy. In contrast, all three
T-cell development provides an excellent model system for studying lineage commitment from a multipotent progenitor. The intrathymic development process has been thoroughly studied. The molecular circuitry controlling it has been dissected and the necessary steps like programmed shut off of progenitor genes and T-cell genes upregulation have been revealed. However, the exact timing between decisio
Lightweight and semi-transparent organic solar cells (ST-OSCs) offer bright promise for applications such as building integrated photovoltaics. Diluting donor content in bulk-heterojunction active layers to allow greater visible light transmittance (AVT) effectively enhances device transparency, yet the ineluctable compromise of the donor-phase continuity is challenging for efficient charge transp
The objective of this thesis has been twofold. Firstly, the purpose has been to examine how the outcomes for tax purposes, at the company level, differ depending on whether the assets transferred in a merger remain attributable to a P.E. in the state of the transferring company, when those assets are subsequently realised with a loss after having decreased in value, post-merger, to a level below t
Wireless Power Transfer (WPT) has become a commercially viable technology. The technology uses the phenomenon of electromagnetic induction between coils to transfer electrical power wirelessly. Due to the increasing interest in WPT, the need to understand how the power transfer between coils behaves in different settings, as well as the ability to simulate the process, have become increasingly imp
IgE is responsible for type 1 mediated allergic reactions, affecting an increased part of the European population. Even though a large part of the population is affected, further being an economical burden for society, little is known about the human IgE repertoire. Variation in antibodies are mainly found in antibody variable domains, and gained understanding of the IgE repertoire can be obtained

The relationship between capital structure and firm performance has been a recurring topic of discussion. Within this context, frameworks such as the Modigliani and Miller, Trade-Off, Market Timing, Pecking Order, Agency theories have been widely examined by researchers, offering diverse viewpoints on how capital structure decisions impact corporate performance in distinct industrial, regional and
To meet the growing demand of meat alternatives, this project was dedicated to creating a chicken analogue prototype with mycoprotein. Within the project, two approaches of alginate gelation, external (diffusion) crosslinking and internal crosslinking, were studied in this particular food matrix. Using the external crosslinking method, the effects of major ingredients on the texture, structure and
En betydande del av alla offentliga upphandlingar leder till upprättande av ramavtal. Ramavtal är avtal som fastställer villkoren för kontrakt som senare ska tilldelas. EU-domstolen har i en dom från 2018 behandlat ett för upphandlingsområdet nytt fenomen. Domen rör takvolymer i ramavtal vilket avser en bestämd gräns för hur mycket som är tillåtet att avropa. Eftersom 2014 års direktiv och sedermA significant part of all public procurements leads to the conclusion of framework agreements. Framework agreements are agreements that define the terms of contracts to be awarded later. In a 2018 judgment, the European Court of Justice dealt with a new phenomenon for the procurement area. The judgment concerns determined volumes in framework agreements, which refer to a specific limit on how muc
Forensic sexual assault samples typically contain a mixture of a small quantity of sperm cells and a high quantity of epithelial cells. This relationship complicates the generation of a DNA profile, which prompts the need for differential lysis and extraction of the DNA. Differential extraction is a lengthy method that includes multiple tube transfers and requires a purification step. Amicon Ultra
