We introduced E-Learning tools in a lecture for computer science freshmen in the winter terms 2002/03 and 2003/04. In both terms, an independent group intensively evaluated the lecture. In the second term, we introduced an interaction tool, which allowed students to interact with the educator. The paper presents the tool, its use and evaluation results.

Phylogenetic analyses have provided strong evidence that amino acid changes in spike (S) protein of animal and human SARS coronaviruses (SARS-CoVs) during and between two zoonotic transfers (2002/03 and 2003/04) are the result of positive selection. While several studies support that some amino acid changes between animal and human viruses are the result of inter-species adaptation, the role of...

In 2001 and 2003, we isolated two H5N1 viruses, A/swine/Fujian/1/01 (SW/FJ/01) and A/swine/Fujian/1/03 (SW/FJ/03), from pigs in Fujian Province, southern China. Genetically, these two viruses are similar, although the NS gene of the SW/FJ/03 virus has a 15-nucleotide deletion at coding positions 612 to 626. The SW/FJ/01 virus is highly lethal for chickens, whereas the SW/FJ/03 virus is nonpatho...

Doctors performing brain surgery by flashlight during a blackout necessitated by a Japanese air raid. The austerity of the surroundings is evident in the lack of medical equipment and supplies. Just as the wounded soldier moves along a pathway from injury, to triage, to care, to recovery, military physicians need to travel along their own pathway of understanding themselves as both physician an...

Glycerol is the major by-product of ethanol fermentation and could be associated with wine quality. A simple method of assaying glycerol, glucose and fructose in wine by highperformance liquid chromatography using a modified polar bonded NH2-silica phase column and a refractive index detector was used to determine their concentrations in highand standard-quality wines. Results show glycerol. fr...

We describe observations of the 2003 outburst of the hard-spectrum X-ray transient 4U 1901+03 with the Rossi X-ray Timing Explorer. The outburst was first detected in 2003 February by the AllSky Monitor, and reached a peak 2.5–25 keV flux of 8×10 ergs cm s (around 240 mCrab). The only other known outburst occurred 32.2 yr earlier, likely the longest presently known recurrence time for any X-ray...

SQL:2007, die sich momentan noch in Entwicklung befindende nächste Version der SQLNorm, erweitert den aus SQL:2003 bekannten SQL-Datentyp ” XML“. Als Instanzen dieses Datentyps sind nun auch komplette XQuery-Sequenzen erlaubt. Infolgedessen können SQL:2007-Anfrageergebnisse vollständige XQuery-Sequenzen als Attributwerte besitzen. Damit stellt sich die Frage, wie XQuery-Sequenzen, die im Anfrag...

This paper may be viewed as a corrigendum as well as an extension of the paper by (Czumaj et al., Theoret. Comput. Sci. 262 (1–2), (2001) 569–582) where they deal with the variable length scheduling problem (VLSP) with parameters k1; k2, denoted VLSP(k1; k2). In the current paper, we >rst discuss an error in the analysis of one of the approximation algorithms described in (Czumaj et al., Theore...

The notion of compensation is widely used in advanced transaction models as means of recovery from a failure. Similar concepts are adopted for providing ‘‘transactionlike’’ behaviour for long business processes supported by workflows technology. In general, it is not trivial to design compensating tasks for tasks in the context of a workflow. Actually, a task in a workflow process does not have...
