Hypoxia affects many important processes in tumour progression and is a key feature in the tumour microenvironment that needs to be taken into account when evaluating prognostics and therapeutic options for cancer patients. Hypoxia-regulating proteins, i.e. hypoxia inducible factors (HIFs), and associated gene products have been linked to certain tumour behaviours and might be useful as prognostic
Diagnosis of discordant twins is easily accomplished with modern ultrasound equipment, though diagnosing twin-to-twin transfusion syndrome (TTS) at an early stage might be a problem. The possibility of excluding TTS by Doppler ultrasound is demonstrated in a case with early severe growth restriction of one fetus. Characteristic blood velocity changes in a dying fetus are also illustrated. The Dop
Software quality is an important factor of a large and complex software system. Hence, there is a need for measuring and controlling quality. Software quality has, however, many different f actors and involves implicit expectations of the behaviour of the software. This thesis investigates two aspects of improving the software quality, in particular the reliability factor. The first part of this
The effects of boiling (10 min) and how differences in cultivars (n = 6), maturity (n = 2), and storage (n = 3) may affect dietary fiber in white cabbage were studied. A great variation in total dietary fiber content between boiled cabbage samples was seen (17.7 to 31.7 g/100 g dry weight basis). Total and insoluble dietary fiber following boiling could be predicted from the initial amount. Averag
Thrombospondins (TSPs) are multidomain oligomers that have complex roles in cell interactions and tissue organisation. The five vertebrate TSPs comprise two subgroups, A and B, that are assembled as trimers or pentamers, respectively. An invertebrate TSP was recently discovered in Drosophila melanogaster, but there is no knowledge of the oligomerisation status or properties of this molecule. We de
Using the HERA-B detector, the b (b) over bar production cross section has been measured in 920 GeV proton collisions on carbon and titanium targets. The b (b) over bar production was tagged via inclusive bottom quark decays into J/psi by exploiting the longitudinal separation of J/psi --> l(+)l(-) decay vertices from the primary proton-nucleus interaction. Both e(+)e(-) and mu(+)mu(-) channels ha
Moisture permeabilities (δv) of mature concrete and cement paste with water-cement ratio (w0/C) 0.4, 0.5 and 0.6 have been determined as functions of the relative humidity (RH). These δv can be used to calculate δv of the aggregates including the interfacial transition zone (ITZ). δv of granite has been preliminarily determined as a function of RH.
We analyze the ripening process where, in a dispersion of vesicles, amphiphile monomers diffuse between vesicles of different sizes, leading to a change in the size distribution. Since, typically, vesicles are not under tension, the driving force for the process comes from the curvature energy. With the conventional expansion of the curvature energy density, g,, to harmonic order we find that the
An experimental and numerical study on mechanical properties, such as strength, elastic modulus, creep and shrinkage, of Self-Compacting Concrete, SCC, and the corresponding properties of Normal Compacting concrete, NC, is outlined in this article. The study included eight mix proportions of sealed or air-cured specimens with water-binder ratio, w/b, varying between 0.24 and 0.80. Half of the mixe
The increasing emissions of carbon dioxide from fossil fuel burning are today thought to be one of the main contributors to global warming. At the same time, developing countries are striving for an increased welfare and burning more fossil fuel, which in turn is augmenting the greenhouse gas effect. In this thesis the current understanding of the connection between greenhouse gases and the climat
Visual quality assurance techniques focus on the detection and qualification of abnormal structures in the image of an object. The features of abnormality are extracted through image mining, whereupon classification is performed on characteristic combinations. Many techniques for feature extraction have been proposed, but the feed-forward neural network is seldom utilized despite its popularity in
Soft photons inside hadronic jets converted in front of the DELPHI main tracker (TPC) in events of qq disintegrations of the Z(0) were studied in the kinematic range 0.2 < E-y < I GeV and transverse momentum with respect to the closest jet direction P-T < 80 MeV/c. A clear excess of photons in the experimental data as compared to the Monte Carlo predictions is observed. This excess (uncorrected fo
Bactericidal/permeability-increasing protein (BPI) is a neutrophil granule protein with potent bactericidal and lipopolysaccharide (LPS)-neutralizing activities. The purpose of this study was to determine if a human recombinant BPI product, rBPI23, would influence neutrophil (PMN) sequestration into various tissues in a rat burn injury model. Leukosequestration may produce local tissue injury from
The parameters important for an optimisation of cloud point extraction in technical scale were investigated using a genetically engineered fusion protein derived from endoglucanase I expressed in Trichoderma reesei and the nonionic polyoxyethylene Agrimul NRE 1205. The key parameters are temperature, detergent concentration, and additional salts. These parameters are interdependent, thus there is
The fluid flow through hardened cement paste was theoretically analyzed by introducing the conception of long-range force and the quantitative relationship between permeability and pore size distribution was derived based on the model of intercepting cylindrical pores and the model of parallel porous bodies. Thirteen sets of data of various hardened cement pastes reported by other researchers were
Integrated Circuits, Printed Circuits Boards, and Multi-board systems are becoming increasingly complex to test. A major obstacle is test access, which would be eased by effective standards for the communication between devices-under-test (DUTs) and the test manager. Currently, the Internal Joint Test Access Group (IJTAG) work at micro-level on a standard for interfacing embedded on-chip instrumen
