We look at adaptive time integration in the context of discontinuous Galerkin methods for the three dimensional unsteady compressible Navier-Stokes equations. Several explicit and implicit schemes will be compared. Philipp Birken, Gregor Gassner, Mark Haas and Claus-Dieter Munz

sionaries, native speakers, and ethnographers had previously been aware of the importance of suprasegmentals in the language, Haas was the first to accurately record Creek, the first to develop a phonemic transcription (Haas 1940; 1977b), and the first to provide rules for the placement of what she called "tonal accent." It is one measure of the complexity of the system that some 36 years separ...

The contribution of two blue-green algae species, Anabaena flos-aquae and Microcystis 16 aeruginosa, to the formation of trihalomethanes (THMs) and haloacetic acids (HAAs) was 17 investigated. The experiments examined the formation potential of these disinfection by-products 18 (DBPs) from both algae cells and extracellular organic matter (EOM) during four algal growth 19 phases. Algal cells an...

Many aromatic amines and heterocyclic aromatic amines (HAAs) are known carcinogens for animals, and there is also strong evidence of some in human cancer. The activation of these compounds, including some arylamine drugs, involves N-hydroxylation, usually by cytochrome P450 enzymes (P450) in Family 1 (1A2, 1A1, and 1B1). We previously demonstrated that the bioactivation product of the anticance...

The energy of the free electron gas is calculated in three dimensions. In this calculation an integral over the wave vector space occurs which was solved by Dingle. In the low temperature approximation the integral over the Fermi distribution leads to x/sinh x type expression, called the Dingle’s formula. The spin symmetry is found to modify this formula which determines the oscillation amplitu...

The presence of dissolved organic matter (DOM) in tropical peat water affects the appearance trihalomethanes (THMs) and haloacetic acids (HAAs) natural sources. However, information about THM HAA is still limited. This study was conducted to determine THMs HAAs taken from a canal river Riau Peatland, Indonesia, influenced by seasons tides. DOM measured carbon (DOC) UV254 absorbance. determined ...

On SmSb single crystals synthesized from elements, the electrical resistance R and magnetization M were measured as functions of temperature magnetic field. A large magnetoresistance is observed over entire range 2-300 K, increasing significantly with decreasing temperature. The dependence exhibits a singularity at transition to antiferromagnetic state T N =2.3 K. At temperatures below 8 de Haa...

There are two types of hyaluronidase inhibitor in noimal human serum; one is destroyed when the serum is heated at 55 C to 60 C for 15 to 30 min, the other is not (Thompson and Moses, 1949). The heat-labile inhibitor, referred to as the nonspecific inhibitor (NSI), is present in the serum of many different species and inhibits testicular and several bacterial hyaluronidases (Haas, 1946). The re...
