Reconstruction of turbulent pipe-flow profiles from laser Doppler velocimetry data
No full textLaser Doppler velocimetry (LDV) is a powerful experimental tool that finds increasing application in industrial research and product development. For example, LDV may be used to support the development of water, heat, and cooling meters as well as the design and validation of the associated testing and calibration facilities. For such applications, a basic quantity of interest is the volume flow rate Q that can be determined through numerical integration of the velocity profile over the measurement grid. However, under realistic experimental conditions, optical disturbances and reflections may cause corrupted and unreliable data at various measurement points. Here, we study a criterium to identify and reconstruct such data points. The reconstruction criterium is based on the standard error associated with each measurement point. Using some of our LDV data, we show that the error in Q with respect to a reference flow rate may be reduced significantly through the reconstruction. Consequently, the reconstruction criterium allows to establish accurate and reliable flow rates that have potential to be used as a primary validation reference

Depolarization and decreased surface expression of K+ channels contribute to NSAID-inhibition of intestinal restitution
No full textNon-steroidal anti-inflammatory drugs (NSAIDs) contribute to gastrointestinal ulcer formation by inhibiting epithelial cell migration and mucosal restitution; however, the drug-affected signaling pathways are poorly defined. We investigated whether NSAID inhibition of intestinal epithelial migration is associated with depletion of intracellular polyamines, depolarization of membrane potential (Em) and altered surface expression of K+ channels. Epithelial cell migration in response to the wounding of confluent IEC-6 and IEC-Cdx2 monolayers was reduced by indomethacin (100μM), phenylbutazone (100μM) and NS-398 (100μM) but not by SC-560 (1μM). NSAID-inhibition of intestinal cell migration was not associated with depletion of intracellular polyamines. Treatment of IEC-6 and IEC-Cdx2 cells with indomethacin, phenylbutazone and NS-398 induced significant depolarization of Em, whereas treatment with SC-560 had no effect on Em. The Em of IEC-Cdx2 cells was: −38.5±1.8mV under control conditions; −35.9±1.6mV after treatment with SC-560; −18.8±1.2mV after treatment with indomethacin; and −23.7±1.4mV after treatment with NS-398. Whereas SC-560 had no significant effects on the total cellular expression of Kv1.4 channel protein, indomethacin and NS-398 decreased not only the total cellular expression of Kv1.4, but also the cell surface expression of both Kv1.4 and Kv1.6 channel subunits in IEC-Cdx2. Both Kv1.4 and Kv1.6 channel proteins were immunoprecipitated by Kv1.4 antibody from IEC-Cdx2 lysates, indicating that these subunits co-assemble to form heteromeric Kv channels. These results suggest that NSAID inhibition of epithelial cell migration is independent of polyamine-depletion, and is associated with depolarization of Em and decreased surface expression of heteromeric Kv1 channels.ID: S0006295207001931; M3: Article; Accession Number: S0006295207001931; Author: L.C.

Het Ir. D.F. Woudagemaal: De relatie tussen de ingrepen in het Ir. D.F. Woudagemaal en de aanwijzingen als rijksmonument en werelderfgoed
No full textHet Ir. D.F. Woudagemaal is het grootste functionerende stoomgemaal ter wereld. Dankzij de technische en bouwkundige waarde, is het Woudagemaal in 1977 aangewezen als rijksmonument door de Rijksdienst voor het Cultureel Erfgoed (RCE). Jaren later, in 1998, is het door de United Nations Educational, Scientific and Cultural Organization (UNESCO) opgenomen in de werelderfgoedlijst. Dit betekent dat het stoomgemaal uniek is en absoluut niet verloren mag gaan. Sinds de oplevering in 1920 is het stoomgemaal van civiel ingenieur en architect Dirk Frederik Wouda (1880-1961) ieder jaar in gebruik gesteld. Door de jaren heen heeft het stoomgemaal enkele veranderingen ondergaan. Desalniettemin is de wisselwerking tussen de innovaties, conservering en de aanwijzing als erfgoed onderbelicht. Het doel van deze thesis is daarom om de volgende vraag te beantwoorden: wat is de relatie tussen de ingrepen in het Ir. D. F. Woudagemaal en de aanwijzingen als rijksmonument en werelderfgoed?AR2A011Architecture, Urbanism and Building Science

Bilateral and unilateral arm training improve motor function through differing neuroplastic mechanisms: a single-blinded randomized controlled trial
No full textBACKGROUND AND PURPOSE:
This randomized controlled trial tests the efficacy of bilateral arm training with rhythmic auditory cueing (BATRAC) versus dose-matched therapeutic exercises (DMTEs) on upper-extremity (UE) function in stroke survivors and uses functional magnetic resonance imaging (fMRI) to examine effects on cortical reorganization.
METHODS:
A total of 111 adults with chronic UE paresis were randomized to 6 weeks (3×/week) of BATRAC or DMTE. Primary end points of UE assessments of Fugl-Meyer UE Test (FM) and modified Wolf Motor Function Test Time (WT) were performed 6 weeks prior to and at baseline, after training, and 4 months later. Pretraining and posttraining, fMRI for UE movement was evaluated in 17 BATRAC and 21 DMTE participants.
RESULTS:
The improvements in UE function (BATRAC: FM Δ = 1.1 + 0.5, P = .03; WT Δ = -2.6 + 0.8, P < .00; DMTE: FM Δ = 1.9 + 0.4, P < .00; WT Δ = -1.6 + 0.7; P = .04) were comparable between groups and retained after 4 months. Satisfaction was higher after BATRAC than DMTE (P = .003). BATRAC led to significantly higher increase in activation in ipsilesional precentral, anterior cingulate and postcentral gyri, and supplementary motor area and contralesional superior frontal gyrus (P < .05). Activation change in the latter was correlated with improvement in the WMFT (P = .01).
CONCLUSIONS:
BATRAC is not superior to DMTE, but both rehabilitation programs durably improve motor function for individuals with chronic UE hemiparesis and with varied deficit severity. Adaptations in brain activation are greater after BATRAC than DMTE, suggesting that given similar benefits to motor function, these therapies operate through different mechanisms

No full textThe six volumes in this series have each the same structure consisting of sixteen parts. Part VI is Los Animales Hablan: La Fabula. Here in Volume VI this part begins on 65 and runs through 76. The T of C at the beginning notes the author of each of the individual fables, here Aesop, G. Civinini, or L. Clasio. The first of the fables here has delightful illustrations across its three pages. El Cangrejo Astuto tells how the crab beats the fox in a race (67-69). There is a lovely illustration of an almond tree on 70. None of the fable illustrations presented in this volume are signed.Language note: SpanishOriginal language: itaBenjamin Jarne
