Supplying air with ball spout air diffusers is a common air-conditioning system for air distribution in large space stadiums. When supplying hot air with ball spout diffusers in winter, the phenomenon of hot jet upturning may appear, so the design should consider adjusting the spout angle so as to c...

The advent of executable contents such as Java applets exposes WWW users to a new class of attacks that were not possible before. Despite an array of security checking, detection , and enforcement mechanisms built into the language model, the compiler, and the run-time system of Java, serious security breach incidents due to implementation bugs have been reported in the past several years. With...

The tRNA m1G9 methyltransferase (Trm10) is a member of the SpoU-TrmD (SPOUT) superfamily of methyltransferases, and Trm10 homologs are widely conserved throughout Eukarya and Archaea. Despite possessing the trefoil knot characteristic of SPOUT enzymes, Trm10 does not share the same quaternary structure or key sequences with other members of the SPOUT family, suggesting a novel mechanism of cata...

Artificial tree hollows (e.g., nest-boxes) are commonly deployed to mitigate the loss of mature trees within human-disturbed landscapes. Their effectiveness as a habitat resource, and thus conservation management tool, is strongly influenced by suitability internal microclimate conditions. In south-eastern Australia, spout nesting resource used diverse community vertebrate species. We tested no...

There are two types of nodes, called “spouts” and “bolts”. A spout is a source of streams (sequences of tuples). In case of the KBA track, a spout would read document data from the provided KBA corpus and emit them as a stream. A bolt receives any number of input streams, does some processing, and may emit new streams. For the KBA track, bolts would determine whether inbound documents from the ...

The "small” spout, 19/64” or 5/16” in diameter, has been widely available to maple producers since the mid to late 1990's as a "healthy" alternative to the traditional 7/16” spout. While now in general use by producers in some regions, particularly those collecting sap by vacuum, the utility of these smaller spouts is still questioned by many sugarmakers, particularly those collecting sap by gr...

Unlike other transfer RNAs (tRNA)-modifying enzymes from the SPOUT methyltransferase superfamily, the tRNA (Um34/Cm34) methyltransferase TrmL lacks the usual extension domain for tRNA binding and consists only of a SPOUT domain. Both the catalytic and tRNA recognition mechanisms of this enzyme remain elusive. By using tRNAs purified from an Escherichia coli strain with the TrmL gene deleted, we...
