We propose and analyse a new finite element method for convection diffusion problems based on the combination of a mixed method for the elliptic and a discontinuous Galerkin method for the hyperbolic part of the problem. The two methods are made compatible via hybridization and the combination of both is appropriate for the solution of intermediate convection-diffusion problems. By construction...

The conventional practice in open cut coal strip mining has been to blast the overburden or coal layers in separate blast events. This is done in order to maximise the benefits from throw blasting and also to limit coal losses. Each blast event usually has a particular design of hole diameters, burdens and spacings, explosive charges and blast timing in order to achieve the required blast outco...

Poroelastography has been re cently in tro duced as a new elastographic tech nique that may be used to de scribe the spa tial and tem po ral be hav ior of poroelastic ma te ri als. The ex per i men tal meth od ol ogy pro posed thus far for phan toms and tis sues in vi tro re quires the ac qui si tion of a precompression rf frame, the ap pli ca tion of a unit step strain com pres sion to the sam...

In order to improve the effectiveness of a previously described1),2) isolated guinea-pig lung technique, the apparatus was redeveloped and modifications were introduced. The artificial thorax volume has been reduced considerably and air conditioning adopted instead of waterbath heating. The cover-plate is equipped with a calibrated orifice, magnetic locking and pass-through electrodes for vagal...

We developed a new in vitro assay for oligosaccharyltransferase (OST), which catalyzes the transfer of preassembled oligosaccharides on lipid carriers onto asparagine residues in polypeptide chains. The asparagine residues reside in the sequon, Asn-X-Thr/Ser, where X can be any amino acid residue except Pro. We demonstrate the potency of our assay using the OST from yeast. In our method, polyac...
