The main objective of the paper is to support and illustrate recent theoretical results on the mathematical modelling of the secondary clarifier. A new settler model is compared with a traditional layer model by means of numerical simulations. Emphasis is put on the numerical solution's ability to approximate the analytical solution of the conservation law written as a non-linear partial different
Control of emission by intermolecular fluorescence resonant energy transfer (IFRET) and intermolecular charge transfer (ICT) is investigated with the quantum-chemistry method using two-dimensional (2D) and three-dimensional (3D) real space analysis methods. The work is based on the experiment of tunable emission from doped 1,3,5-triphenyl-2-pyrazoline (TPP) organic nanoparticles (Peng, A. D.; et a
Magnetotransport in GaAs/AlAs/GaAs single-barrier heterostructures, incorporating unintentional donors in the barrier, is studied. Resonant tunneling is observed through the quasiconfined states in the AlAs layer which originate from the X-XY and X-Z conduction-band minima and through two distinct states of the donors bound to the X-XY and X-Z valleys. This allowes us to determine directly the bin
In this book the authors discuss globalisation, the use of new technology and its effects on higher education. Four old universities in Europe (Bologna, Cambridge, Leuven and Lund) are used as illustrations of different approaches to managing a changing environment. The authors focus on questions like: Differences in organisational structure and strategic choices, how do they affect internationali
Popular Abstract in Swedish Avhandlingen handlar om lungornas funktion hos för tidigt födda (prematura) barn med brist på surfaktant, ett ämne som normalt ska finnas i lungorna, och hur lungfunktionen hos sådana barn kan förbättras genom tillförsel av det saknade ämnet utifrån. I avhandlingen har också använts en djurmodell (för tidigt födda lamm) för att studera hur konstgjord andning vid födelseThe thesis investigates lung function and the effects of rescue surfactant treatment in mechanically ventilated preterm human infants with respiratory distress syndrome (RDS), and the effects of ventilation at birth on the response to surfactant supplementation in preterm lambs. To assess lung function, the author recorded static pressure-volume (P-V) curves during passive deflation from total lun
Endovascular expanding metallic stents were percutaneously implanted in the iliac arteries and veins of pigs. The vessels had been stenosed by a ligature of catgut 4 weeks prior to this. Platelets were labeled with Indium 111 and the deposition onto the dilated and stented areas was dynamically registered for 240 min with a scintillation camera. All six arterial and six venous stents remained pate
Analysis of the serum concentrations of free thyroid hormones (fT3, fT4) and thyrotropin (TSH) in 173 psychogeriatric patients (94 females and 79 males, mean age 79 +/- 8 years) disclosed that the hormone levels were related to sex, psychiatric diagnosis, medication and the presence of nonthyroid illness (NTI). Subnormal concentrations of thyroid hormones and/or TSH were found in 25% of the patien
Two complexes were isolated from aqueous Pd(NO3)(2)-Na(2)H(2)EDTA solutions and studied by single crystal X-ray diffraction, IR/Raman spectroscopy, and photoelectron spectroscopy. The first complex, Pd(Hkpda)(2) (kpda = ketopiperazinediacetate dianion, C8H10N2O5). forms yellow parallelepipeds during slow evaporation of Pd(NO3)(2)-Na(2)HEDTA solution at 25degreesC, and is a result of EDTA oxidation
Vid intrakraniell patologi, speciellt om patienten är medvetslös, är kunskap om det intrakraniella trycket av särskilt värde i neurointensivvård. Intraventrikulär kateter för mätning av intrakraniellt tryck har varit etablerad standard i årtionden. Exakta mätningar är möjliga endast genom invasiva tryckmätare. För att undersöka sambandet mellan intrakraniellt tryck och pulsatilt index, erhållet me
Popular Abstract in Swedish Politiska beslut föranleder ekonomiska agenter att organisera sig i intressegrupper och att agera strategiskt både i ekonomiska beslut och genom lobbyingaktiviteter, för att förbättra den situation som uppstår till följd av politiska beslut. Denna avhandling består av fyra artiklar som behandlar olika former av intressegruppsinflytande under olika institutionella formerPolitics induce economic agents to organise into special interest groups (SIGs) and act strategically to adjust their economic decisions and to conduct rent-seeking activities in order do improve the situation inflicted on them by policy. This thesis examines, in four essays, different forms of SIG influence on public policy in different institutional contexts. The two first essays examine two rel
The pleckstrin homology (PH) domain is extended in the Btk kinase family by a region designated the TH (Tee homology) domain, which consists of about 80 residues preceding the SH3 domain. The TH domain contains a conserved 27 amino acid stretch designated the Btk motif and a proline-rich region. Sequence similarity was found to a putative Pas GTPase activating protein and a human interferon-gamma
Based on a comparative analysis approach of oasis distributed in arid area of Northwest China, this paper brings up and describes two kinds of oasis distribution pattern: mid-lower reach pattern and middle reach pattern. It is found that the water availability per capita of mid-lower reach pattern is higher than that of middle reach pattern, while the water resources exploitation percentage of mid
Excited states in (196)AU, populated in the Pt-196(p,n) and (d,2n) reactions, were investigated by in-beam gamma -ray and conversion-electron spectroscopy. Two only weakly connected level structures, built on the 2(-) ground state (negative-parity level scheme) and on the 5(+) isomer at 84.7 keV (positive-parity level scheme), are observed. The point of main effort of the present work was the inve
Pancreatitis-associated lung injury is an early-occurring and severe complication, still associated with substantial mortality. A number of inflammatory cells and their products are involved in the initiation and progress of the condition. In the present study, acute pancreatitis (AP) was induced by the intraductal infusion of 5% sodium taurodeoxycholate in the rat. Pulmonary endothelial barrier d
TNP-470 is an acknowledged anti-angiogenic factor, and was studied clinically as an anti-cancer drug. We previously reported on an additional property of this molecule: the intracellular generation of reactive oxygen species in B16F10 melanoma cells. We showed that a massive generation of ROS occurred in the first few hours after treatment with TNP-470 and that this event was critical to subsequen
Popular Abstract in Swedish Vanligt viloelektrokardiogram (EKG) med 12 avledningar är ett av de mest använda redskapen för diagnostik av hjärtsjukdom. Tidigare forskning har visat att detta EKG ej är optimalt, men att nya EKG-metoder kan ge viktig tilläggsinformation. En metod som i flera tidigare studier visat sig innehålla diagnostisk potential är analys av de högfrekventa signalkomponenterna i The standard 12-lead electrocardiogram (ECG) is one of the most commonly used methods for diagnosing heart disease. Standard ECG is not always optimal, however, and new ECG methods can provide additional information. Analysis of high-frequency QRS components (HF-QRS) has been shown to increase the diagnostic performance of the ECG. Since the amplitudes of the HF-QRS are low compared with those vis
