Pfam is a collection of multiple alignments and profile hidden Markov models of protein domain families. Release 3.1 is a major update of the Pfam database and contains 1313 families which are available on the World Wide Web in Europe at http://www.sanger.ac.uk/Software/Pfam/ and http://www.cgr.ki.se/Pfam/, and in the US at http://pfam.wustl.edu/. Over 54% of proteins in SWISS-PROT-35 and SP-Tr...

We present low-state IUE spectroscopy of the ROSAT-discovered polar RX J1313.2−3259. The SWP spectrum displays a broad Lyα absorption profile, which can be fitted with a two-temperature model of a white dwarf of T wd = 15 000 K with a hot spot of T spot = 34 000 K which covers f ∼ 0.01 of the white dwarf surface. The white dwarf temperature is atypically low for the long orbital period (4.18 h)...

The initiation of the Global Nuclear Energy Partnership includes nuclear-based transmutation devices to recycle the spent fuel. Fusion can offer an alternative to the use of fast reactors for the transmutation of actinides. At a modest fusion power of 20 MW, a Z-Pinch driven sub-critical blanket can burn actinides and produce power. Several engineering issues have been examined: the effect of t...

Cazin, John, Jr. (University of Iowa, Iowa City), and David W. Decker. Growth of Allescheria boydii in antibiotic-containing media. J. Bacteriol. 90:1308-1313. 1965.-Thirteen isolates of Allescheria boydii were surveyed for their ability to grow and sporulate on media containing cycloheximide and chloramphenicol. The fungus grew well in the presence of 4 to 8 mg/ml of cycloheximide, whereas asc...

The publisher regrets that the published version of the above article contained several printing errors. Namely that the citations in the text to the Erkelens and van Ee reference (in press) should have been changed to (2002). Also many possessives (’s) were deleted unnecessarily. In addition, in the second line of the abstract (p. 2??) should have been changed to (p. 1157), on line 10 in the l...

This short note presents a discussion arisen after reading ”Development a new mutation operator to solve the Traveling Salesman Problem by aid of Genetic Algorithms”, by Murat Albayrak and Novruz Allahverdi, (2011). Expert System with Applications (38)(pp. 1313-1320). The discussed paper presents a new greedy mutation operator to solve the well-known Traveling Salesman Problem. To prove the qua...

Optical studies of ultraluminous X-ray sources (ULX) in nearby galaxies have turned out to be instrumental in discriminating between various models including the much advertised intermediate mass black hole hypothesis and various beaming scenarios. Here we report on ESO VLT and SUBARU observations of ULX that have revealed the parent stellar clusters with ages of some 60 million years in two ca...
