Convergence of implicit finite difference methods applied to nonlinear mixed systems
A new technique to prove convergence of finite difference methods applied to nonlinear PDEs arising in computational fluid dynamics is presented. The underlying systems may be hyperbolic, parabolic or of mixed type like the Navier-Stokes equations. Implicit finite difference methods are analyzed. The essential idea leading to success is the introduction of a pilot function that is highly attractiv
Effects of Asthma Combination Therapy on Extracellular Matrix Remodeling in Human Lung Fibroblasts
Fibroblasts, being one of the resident and structural cells of the lung, have the capacity to produce inflammatory mediators, cytokines and extracellular matrix (ECM) proteins perpetuating the inflammation in the airways of asthmatics. Airway remodeling is also a prominent feature of asthma that affects the lung function causing a thickening of the airways. An increased ECM production of proteogly
Plasma neutrophil lipocalin, elastase-alpha1-antitrypsin complex and neutrophil protease 4 in preterm infants with respiratory distress syndrome.
Optimizing conditions for poly(beta-hydroxybutyrate) production by Halomonas boliviensis LC1 in batch culture with sucrose as carbon source
Halomonas boliviensis LC1 is able to accumulate poly(beta-hydroxybutyrate) (PHB) under conditions of excess carbon source and depletion of essential nutrients. This study was aimed at an efficient production of PHB by growing H. boliviensis to high cell concentrations in batch cultures. The effect of ammonium, phosphate, and yeast extract concentrations on cell concentration [cell dry weight (CDW)
Development of a carbon nanotube paste electrode osmium polymer-mediated biosensor for determination of glucose in alcoholic beverages
This paper describes a new amperometric biosensor for glucose monitoring. The biosensor is based on the activity of glucose dehydrogenase (GDH) and diaphorase (DI) co-immobilized with NAD(+) into a carbon nanotube paste (CNTP) electrode modified with an osmium functionalized polymer. This mediator was demonstrated to shuttle the electron transfer between the immobilized diaphorase and the CNTP ele

Successful mobilization of Ph-negative blood stem cells with intensive chemotherapy plus G-CSF in patients with chronic myelogenous leukemia in first chronic phase
The aim of the study was to investigate the feasibility of mobilizing Philadelphia chromosome negative (Ph-) blood stem cells (BSC) with intensive chemotherapy and lenograstim (G-CSF) in patients with CML in first chronic phase (CP1). During 1994-1999 12 centers included 37 patients 556 years. All patients received 6 months' IFN, stopping at median 36 (1-290) days prior to the mobilization chemoth

Reliability and responsiveness of elbow trajectory tracking in chronic poststroke hemiparesis
This study established the reliability of a novel upper-limb trajectory-tracking task for assessment of perceptual motor control in hemiparetic adults. Eleven persons with chronic poststroke hemiparesis (mean 58.6 months) and eleven nondisabled control subjects performed an elbow flexion-extension task against a low-resistance isotonic load at three speeds: 25degrees/s, 45degrees/s, and 65degrees/
Embodied Rituals and Ritualized Bodies : Tracing Ritual Practices in Late Mesolithic Burials
This thesis explores the ritual dimensions of the mortuary practices in the late Mesolithic cemeteries at Skateholm in Southern Sweden and Vedbæk-Bøgebakken in Eastern Denmark. With a combination of methods and theories that all focus on the ritual practices as action, a new approach to burials in archaeology is proposed. Special attention is given to the treatment of the body after death, which i
Solvent extraction of hydrofluosilicic acid with alamine 336
Extraction constants for the solvent extraction of hydrofluosilicic acid with Alamine 336 have been determined. Two species were identified, (R3NH+ )2 SiF62- and R3NH+ HSiF6, whose respective extraction constants were determined to be log K21 = 7.42 and log K11 = 2.60. For the dissociation of hydrofluosilicic acid the activity coefficient model presented by Bromley was adapted to sulphuric acid an
Steady-state cyclic electron transfer through solubilized Rhodobacter sphaeroides reaction centres
The mechanism, thermodynamics and kinetics of light-induced cyclic electron transfer have been studied in a model energy-transducing system consisting of solubilized Rhodobacter sphaeroides reaction center/light harvesting-1 complexes (so-called core complexes), horse heart cytochrome c and a ubiquinone-0/ubiquinol-0 pool. An analysis of the steady-state kinetics of cytochrome c reduction by ubiqu
Effect of hydrophilically modified graft polystyrene on AOT oil-continuous microemulsions: Viscosifying effects of P(S-g-PEO) as a function of graft chain length and graft density
The effect of hydrophilically modified polystyrene, poly(styrene-g-poly(ethylene oxide)), P(S-g-PEC), on the viscosity of ACT oil-continuous microemulsions has been investigated as a function of PS and PEO chain lengths and PEO chain density. A series of polymers, P (S-g-PEO) with PEO chain lengths of 23 or 9, and different graft densities were synthesized by living radical polymerization. Thus, a
Oedema-related tissue damage after temporary and permanent occlusion of the middle cerebral artery
Eleven adults spontaneously-hypertensive male rats (SHR) were studied 22 h or 7 days after a 2 h unilateral occlusion of the right middle cerebral artery (MCA). Another 11 SHR were studied after 24 h or 7 days of permanent MCA ligation. The brain infarcts were significantly larger (P < 0.05) after permanent occlusion than after a 2 h occlusion. More extensive and widespread vasogenic oedema, emana
The use of eco-labeling like initiatives on food products to promote quality assurance - is there enough credibility?
The development of this paper was inspired by the increase in the number of different eco-label like quality assurance schemes established in the European Union in the past few years. These schemes are flooding the market and the researchers raise the question, is there enough credibility in these schemes? This piece of research is based on 58 eco-labeling like food schemes and dissects them into
