چکیده
The nsmb code (Navier-Stokes Multi-Block) solves the fully coupled system of equations simultaneously using a cell-centered finitevolume approach. This note assesses the sensitivity to some turbulence models and numerical schemes implemented in nsmb when computing two test cases in standard mode, that is, without tuning the code to these two cases. The cases are 1. subsonic flow around the ms(1)-0313 airfoil, and 2. transonic flow around the onera m6 wing, using various combinations of models (algebraic Baldwin-Lomax or Granville, oneequation Spalart-Allmaras or the two-equation k − model of Chien) together with a numerical scheme of either the secondorder central or third-order Roe upwind type.

Heterologously expressed inner lipoyl domain of dihydrolipoyl acetyltransferase inhibits ATP-dependent inactivation of pyruvate dehydrogenase complex. Identification of important amino acid residues.
The activity of the pyruvate dehydrogenase multienzyme complex (PDC), which catalyses the oxidation of pyruvate to acetyl-CoA within the mitochondrion, is diminished in animal models of diabetes. Studies with purified PDC components have suggested that the kinases responsible for inactivating the decarboxylase catalytic subunits of the complex are most efficient in their regulatory role when th...
متن کاملCloning and characterization of two pyruvate decarboxylase genes from Pichia stipitis CBS 6054.
In Pichia stipitis, fermentative and pyruvate decarboxylase (PDC) activities increase with diminished oxygen rather than in response to fermentable sugars. To better characterize PDC expression and regulation, two genes for PDC (PsPDC1 and PsPDC2) were cloned and sequenced from P. stipitis CBS 6054. Aside from Saccharomyces cerevisiae, from which three PDC genes have been characterized, P. stip...
متن کاملO-12: Studies on Sequestration of PDC-109 Protein on Cryodamage and In Vitro Fertility of Crossbred Bull Spermatozoa
Background: Plasma membrane of the spermatozoa interacts with and is altered by abundant seminal PDC-109 present in their immediate milieu in vivo with damaging effect in a time- and concentration- dependent manner. Therefore we hypothesized that sequestration of detrimental protein from ejaculates would be beneficial for cryopreservation of sperm cells. To this aim we evaluated the effect of s...
متن کاملEffects of pyruvate decarboxylase overproduction on flux distribution at the pyruvate branch point in Saccharomyces cerevisiae.
A multicopy plasmid carrying the PDC1 gene (encoding pyruvate decarboxylase; Pdc) was introduced in Saccharomyces cerevisiae CEN. PK113-5D. The physiology of the resulting prototrophic strain was compared with that of the isogenic prototrophic strain CEN.PK113-7D and an empty-vector reference strain. In glucose-grown shake-flask cultures, the introduction of the PDC1 plasmid caused a threefold ...
متن کاملIdentification and precursor frequency analysis of a common T cell epitope motif in mitochondrial autoantigens in primary biliary cirrhosis.
The immunodominant antimitochondrial antibody response in patients with primary biliary cirrhosis (PBC) is directed against the E2 component of the pyruvate dehydrogenase complex (PDC-E2). Based on our earlier observations regarding peripheral blood mononuclear cell (PBMC) T cell epitopes, we reasoned that a comparative analysis of the precursor frequencies of PDC-E2 163-176-specific T cells is...
