This research investigates the relationship between post fault transient overvoltages and the functionality of the digital distance protection. The study is conducted in a 66kV network with a neutral earth resistor as method to earth the power system. This paper begins by performing an extensive power system analysis on ground fault transient overvoltages. The study is conducted by using the PSCAD-EMTC software package.

The paper describes the modelling of primary pumps in advanced sodium cooled reactors using the TRACE code. Following the implementation of the models, the results obtained in the analysis of different design basis transients are compared with the simplifying approximations used in reference models.

The results of simulated transients for three typical PWR accidents are presented: a turbine trip with station blackout, a large break loss of coolant accident and a small break loss of coolant accident. The analyses show that the safety criteria are respected and that the reactor quickly reaches a safe shutdown state without operator action and external power.

The studies presented in this paper are performed in the general framework of transient coupled calculations with accurate neutron kinetics models able to characterize spatial decoupling in the core. An innovative fission matrix interpolation model has been developed with a correlated sampling technique associated to the Transient Fission Matrix (TFM) approach.

This paper presents an analytical and a numerical thermomechanical investigation of a thick-walled cylinder made of the functionally graded materials (FGMs). The hollow cylinder is subjected to a pressure and a thermal load and the properties of this material are varying across the thickness from the inner face that is a ceramic to the outer one which is a metal.

In this study we describe the isolation of three genes of the CYP11B family of the guinea pig. CYP11B1 codes for the previously described 11b-hydroxylase [Bulow, H.E., Mobius, ¨ ¨ K., Bahr, V. & Bernhardt, R. (1996) Biochem. Biophys. Res. ¨ Commun. 221, 304–312] while CYP11B2 represents the aldosterone synthase gene. As no expression for CYP11B3 was detected this gene might represent a pseudogene.

During the development of multicellular organisms, both transient and stable gene expression patterns have to be established in a precisely orchestrated sequence. Evidence from diverse model organisms indicates that this epigenetic program involves not only transcription factors, but also the local structure, composition, and modification of chromatin, which define and maintain the accessibility and transcriptional competence of the nucleosomal DNA template.

The process of pressure-induced modification of horse liver alcohol dehydrogenase (HLADH) was followed by measuringin situ catalytic activity (up to 250 MPa), intrinsic fluorescence (0.1–600 MPa) and modifications of FTIR spectra (up to 1000 MPa). The tryptophan fluor-escence measurements and the kinetic data indicated that the pressure-induced denaturation of HLADH was a process involving several transitions and that the observed transient states have characteristic properties of molten globules. ...

With the amount of genetic information available, a lot of attention has focused on systems biology, in particular biomolecular interactions. Con-sidering the huge number of such interactions, and their often weak and transient nature, conventional experimental methods such as X-ray crystal-lography and NMR spectroscopy are not sufficient to gain structural insight into these. A wealth of biochemical and⁄or biophysical data can, however, readily be obtained for biomolecular complexes.

Mitochondrial biogenesis is a complex and highly regulated process that requires the controlled expression of hundreds of genes encoded in two separated genomes, namely the nuclear and mitochondrial genomes. To identify regulatory proteins involved in the transcriptional control of key nuc-lear-encoded mitochondrial genes, we have performed a detailed analysis of the promoter region of theasubunit of the Drosophila melanogasterF1F0 ATP synthase complex.

There is mounting evidence that the vanilloid (capsaicin) receptor; transient receptor potential channel, vanilloid subfamily member 1 (TRPV1), is subjected to multiple interacting levels of control. The first level is by reversible phosphorylation catalyzed by intrinsic kinases (e.g. protein kinase A and C) and phosphatases (e.g. calcineurin), which plays a pivotal role in receptor sensitization vs. tachyphy-laxis.

The transient receptor potential channel vanilloid receptor subunit 1 (TRPV1) is amolecular integrator of physical and chemical stimuli in the peripheral nociceptor terminals. TRPV1 is an ionotropic channel that plays a critical role in both thermal nociception and inflammatoryhyperalgesia. Structure–function relationships are providing fundamental insights of the modular architecture of this neuronal recep-tor.

We recently reported that the transient expression of polyglutamine tracts of various size in exon 1 of the huntingtin polypeptide (httEx1) generated abnormally high levels of intracellular reactive oxygen species that directly contributed to cell death. Here, we compared the protection generated by heat shock proteins to that provided by the antioxidant agentN-acetyl-l-cysteine.

In an attempt to identify potential therapeutic targets for the correction of muscle wasting, the gene expression of several pivotal proteins involved in protein metabolism was investigated in experimental atrophy induced by transient or definitive denervation, as well as in four animal models of muscular dystrophies (deficient for calpain 3, dysferlin,a-sarcoglycan and dystrophin, respectively).
