The crystal structure of the title compound, [NH(3)(CH(2))(2)NH(3)][Cd(SO(4))(2)(H(2)O)(4)], consists of [Cd(SO(4))(2)(H(2)O)(4)](2-) anions that are built from octa-hedral Cd(H(2)O)(4)O(2) and SO(4) tetra-hedral units linked by corner sharing. The ethyl-ene-diamminium cations are linked to the anions via N-H⋯O hydrogen bonds. The asymmetric unit contains one-half of the compound, the other hal...

MOTIVATION Effective algorithms for finding relatively weak motifs are an important practical necessity while scanning long DNA sequences for regulatory elements. The success of such an algorithm hinges on the ability of its scoring function combined with a significance analysis test to discern real motifs from random noise. RESULTS In the first half of the paper we show that the paradigm of ...

Concrete Vibration can take some time ans sometimes it just seems to take longer than it should to pour and consolidate a precast product, such as concrete pipe or a manhole section. Frustrated by sluggish procedures, The Cretex Companies’ Rapid City, South Dakota, plant determined to improve on the half hour it took to pour zeroslump concrete, consolidate it, and get the top ring in place on t...
