چکیده
Korrosionsprobleme traten an den Kesselwän den von Wirbelschichtkesseln auf, in denen 100 % Altholz unter „Low-NOxVerhältnissen“ verbrannt wurde. In einem ersten Schritt zum Verständnis der Auswirkungen des Brennstoffs wurden Ablagerungen an verschiedenen Positi onen der unteren Kesselwände gesammelt und analysiert. Ein großer Teil dieser Kesselwände war mit der Nickel-Basis-Legierung Alloy 625 beschichtet.

Die Deregulierung des Energiemarktes und die zunehmende Integration erneuerbarer Energieerzeugung in das Netz haben zu neuen, hochdynamischen Anforderungen an die Kraftwerke geführt, die mit klassischen Regelungen vom PID-Typ teilweise nicht mehr zu bewältigen sind. In dem vorliegenden Beitrag wird ein moderner, multivariabler Regler zur Regelung des Füllstandes der Niederdrucktrommel im 450-MW...
متن کاملConcentric visual field restriction under vigabatrin therapy: extent depends on the duration of drug intake
Vigabatrin (VGB) is a novel antiepileptic drug which inhibits GABA-transaminase (GABA-T) and thus increases the level of GABA in the CNS and in its neurons. In the last few years, evidence has been presented that VGB intake may be associated with concentric visual field restrictions. The aim of this study was to estimate the prevalence of visual field constrictions and to determine if, and to w...
متن کاملVigabatrin-Induced Generalized Epileptiform Discharges in a Patient with Focal Epilepsy

This report is about the repetitive appearance of generalized spike-and-wave complexes in a patient with focal epilepsy. Though there were constant appearances of the generalized epileptiform discharges on the consecutive electroencephalograms (EEGs) taken over appr...

متن کاملMonitoring vigabatrin in head injury patients by cerebral microdialysis: obtaining pharmacokinetic measurements in a neurocritical care setting
AIMS The aims were to determine blood-brain barrier penetration and brain extracellular pharmacokinetics for the anticonvulsant vigabatrin (VGB; γ-vinyl-γ-aminobutyric acid) in brain extracellular fluid and plasma from severe traumatic brain injury (TBI) patients, and to measure the response of γ-aminobutyric acid (GABA) concentration in brain extracellular fluid. METHODS Severe TBI patients ...
