A model is presented that describes the pumping characteristics of St707 getter material, the evaporation rate of antimony, and the resulting partial pressure of Sb within a vacuum chamber. The results show that within the 250-450◦C range, the partial pressure of antimony ranges from 10−7 Pa to 10−2 Pa. In a limiting case where the getter efficiency is tuned to 10, 000 L/s, partial pressures ar...

We report carbon nanotube thin film-based supercapacitors fabricated with printing methods, where electrodes and separators are integrated into single sheets of commercial paper. Carbon nanotube films are easily printed with Meyer rod coating or ink-jet printing onto a paper substrate due to the excellent ink absorption of paper. A specific capacity of 33 F/g at a high specific power of 250 000...

TransTerm is a database of initiation and termination sequence contexts from more than 250 organisms listed in GenBank, including the four complete genomes:Haemophilus influenzae, Methanococcus jannaschii, Mycoplasma genitalium,and Saccharomyces cerevisiae. For the current release, more than 60 000 coding sequences were analysed. The tabulated data include initiation and termination contexts or...

BACKGROUND Firearms may be obtained illegally from federally-licensed dealers and pawnbrokers through surrogate (straw) purchases, undocumented purchases and theft. Some retailers knowingly make illegal sales. OBJECTIVE To obtain information about the frequency of and risk factors for these events, and retailers' reactions to them, directly from licensed retailers. METHODS Survey of a rando...

A hemagglutinin was purified from the coelomic fluid of the sea urchin Anthocidaris crassispina by ion-exchange chromatography on DEAE-cellulose and affinity adsorption to glutaraldehyde-fixed ghosts of human erythrocytes, followed by elution with 10 mM EDTA. On sodium dodecyl sulfate-polyacrylamide gel electrophoresis, it showed a single protein band with a molecular weight of 13 000 and 26 00...

Although cholangiocarcinoma (CCA) is usually a rare cancer, in northeast Thailand it kills 20 000 or more people every year. The prognosis is very poor owing to late stage diagnosis, with palliative treatment often representing the only option. In this area of predominantly rural Thailand, CCA is associated with infection with the liver fluke, Opisthorchis viverrini, which is classified as a gr...

Context. We report on the physical properties of small-scale transient flows observed simultaneously at high cadence with the SUMER spectrometer and the TRACE imager in the plage area of an active region. Aims. Our major objective is to provide a better understanding of the nature of transient phenomena in the solar atmosphere by using high-cadence imager and spectrometer co-observations at sim...
