In previous papers of this series the temperature-dependent Raman spectra of poly(dA).poly(dT) and poly(dA-dT).poly(dA-dT) were used to characterize structurally the melting and premelting transitions in DNAs containing consecutive A.T and alternating A.T/T.A base pairs. Here, we describe procedures for obtaining thermodynamic parameters from the Raman data. The method exploits base-specific an...

A nodally exact scheme is derived for a model equation in 1D involving zeroth and second order terms. The method is derived using residual-free bubbles in conjunction with the Galerkin approximation. It is shown that this approach leads to the mass lumping scheme for su ciently small mesh sizes. 1. The residual-free bubbles approach. The usage of the Galerkin method enriched with bubble functio...

I.2 Soit Vh l’espace d’éléments finis P k, c’est-à-dire l’espace des fonctions continues, qui sont polynomiales (de degré k) par morceaux sur un maillage du domaine Ω. Le problème discrétisé s’écrit : trouver uh ∈ Vh tel que pour tout vh ∈ Vh, a(uh, vh) = l(vh). Comme Vh ⊂ H1 0 (Ω), on a, pour tout vh ∈ Vh, a(u− uh, vh) =, 0 et donc a(u− uh, u− uh) = a(u− uh, u− vh). On en déduit facilement que...

The aim of this study was to assess the effect of some foods consumed previous to an erosive beverage on dental enamel and cement. The study was performed on 40 human teeth unaffected, extracted for orthodontic braces. The teeth were cut to obtain 80 cervical slices including enamel and dentine/cement areas. The slices were randomly divided in four groups. The 20 samples of control group (group...

introduction: in this study, we investigated the role of n-methyl-d-aspartate (nmda) receptors in the ventral hippocampus (vh) and their possible interactions with gabaa system on anxiety-like behaviors. methods: we used an elevated-plus maze test (epm) to assess anxiety-like behaviors and locomotor activity in male wistar rats. results: the results showed that intra-vh infusions of different d...

VH replacement occurs through RAG-mediated secondary recombination between a rearranged VH gene and an upstream unrearranged VH gene. Due to the location of the cryptic recombination signal sequence (cRSS, TACTGTG) at the 3' end of VH gene coding region, a short stretch of nucleotides from the previous rearranged VH gene can be retained in the newly formed VH-DH junction as a "footprint" of VH ...
