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
Background: Bladder outlet obstruction, commonly resulting from benign prostatic hyperplasia or congenital urethral valves, is a prevalent cause of voiding dysfunction. This condition induces significant bladder hypertrophy, alters excitability, and increases residual urine. Obstruction has been extensively studied in experimental animal models using surgical obstruction. A frequent pathological e
Study region: Lake Vänern, the largest lake in the European Union, located in Sweden. Study focus: The study aimed to develop a spatially complete and temporally continuous lake surface water temperature (LSWT) dataset by fusing satellite remote sensing data with reanalysis products. Five satellite-derived LSWT products, including the Moderate Resolution Imaging Spectroradiometer (MODIS), were eva
Background: Management of traumatic spinal cord injury is complex and depends on a multidisciplinary approach involving pre-hospital services, spinal surgery, intensive care unit treatment and specialized rehabilitation. International clinical practice guidelines for the handling of these patients offer specific recommendations regarding transportation, radiological investigations, timing of surge
Background & aims: Colorectal cancer (CRC), particularly rectal cancer, often requires neoadjuvant radiotherapy (RT) as part of its treatment plan. Although effective, RT can cause significant gastrointestinal side effects. Because the onset of RT-induced tissue injury can be anticipated, there is an opportunity to apply preventive measures before the damage occurs. This study aimed to assess
The delay between the origin of animals in the Neoproterozoic and their Cambrian diversification remains perplexing. Animal diversification mirrors an expansion in marine shelf area under a greenhouse climate, though the extent to which these environmental conditions directly influenced physiology and early organismal ecology remains unclear. Here, we use a biogeochemical model to quantify oxygen
We address the structure of homogeneous mixtures of equal volumes of water and oil rendered miscible by the addition of amphiphilic molecules. Specifically, we study the pathway from regular ternary solutions to structured microemulsions with increasing amphiphilic chain length, i.e., increasing i and j for alkyl polyglycol ether surfactants (CiEj) from C3E0 (i.e., propanol) to C5E2, using contras
