The -145 km/s Absorption System of Eta Carinae

With the STIS E230H mode (R 118,000), we have identified about twentyabsorption components in line of sight from Eta Carinae. Two components,one at -513 km/s and another at -145 km/s, are quite different incharacter from the others, mostly at intermediate velocities (Seeadjacent posters by T. Gull and A. Danks). The -145 km/s component issignificantly wider in fwhm, is seen in many more species, a

Improving initial xylose metabolism in recombinant Saccharomyces cerevisiae

The aim of the thesis is to improve the initial steps of xylose metabolism in recombinant Saccharomyces cerevisiae. S. cerevisiae takes up xylose of poor affinity by means of hexose transporters. Metabolic control analysis was used to investigate whether the low xylose utilisation rate is due to inefficient transport. Xylose transport was found to have little control over the aerobic xylose utili

Analysis of User Demand Patterns and Locality for Youtube traffic

Video content constitutes a large share of residential Internet traffic. The major source of video content as of today is YouTube. In this paper, we analyse the user demand patterns for YouTube in two metropolitan access networks with more than 1 million requests over three consecutive weeks in the first network and more than 600,000 requests over four consecutive weeks in the second network. In p

The Metal Beaker with Embossed Foil Bands

The metal beaker that was found in the house is a unique object. The shape arouses associations with late antique glasses. The beaker is covered with embossed gold bands with figure representations carried out in early Style I. The bands were probably produced around 500 AD. The body of the beaker might be contemporaneous or possibly also older, with the bands as a later addition. The beaker is co

Multipath propagation simulator for V2X Communication Tests on Cars

Test and evaluation of wireless communication performance with cars can be done in many ways. One approach, for both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) tests, is to use a multipath propagation simulator to achieve realistic signal environments for the different communication systems under test. Multipath propagation simulators have previously been shown to be useful for t
