Bacteriophages and cryogels: A new efficient tool in bioseparation

Abstract Due to developments in the last decades in the field of protein production, new technologies for bio-separation have evolved. Especially in the field of affinity chromatography, the search for new ligands is of great interest. Besides the antibodies used as affinity ligands, synthetic ligands were introduced. Textile dyes were a first group to be introduced but despite their selectivity a

Xilinx Virtex II Pro implementation of a reconfigurable UMTS digital channel filter

A reconfigurable digital root raised cosine (RRC) filter for a UMTS terrestrial radio access (UTRA) mobile terminal receiver is implemented on a Xilinx Vitrex II Pro Field Programmable Gate Array (FPGA). The filter employs a finite impulse response (FIR) and monitors in-band and out-of-band received signal powers and calculates the appropriate filter length that meets the bit-energy to interferenc

The Virgin in Hades

Christian imagination engaged Hades from the very beginning; already the canonical epistle 1 Peter talks of preaching among the dead. Synesius of Cyrene’s hymns and the Odes of Solomon exemplify, in different ways, how early Christian poets use the katabasis motif. Most of the early texts describe Christ’s visit to the underworld.
