Various N-substituted benzisoselenazol-3(2H)-ones and their non-selenium-containing analogues have been synthesized and tested against selected viruses (HHV-1, EMCV and VSV) to determine the extent to which selenium plays a role in antiviral activity. The data presented here show that the presence of selenium is crucial for the antiviral properties of benzisoselenazol-3(2H)-ones since their iso...

Every word to utter from the writer involves the element of this life. The writer really shows how the simple words can maximize how the impression of this book is uttered directly for the readers. Even you have known about the content of a death of ones own so much, you can easily do it for your better connection. In delivering the presence of the book concept, you can find out the boo site here.

A lower time bound Ω(min(ν(x), n − ν(x)) for counting the number of ones in a binary input word x of length n corresponding to the word length of a processor architecture is presented, where ν(x) is the number of ones. The operations available are increment, decrement, bit-wise logical operations, and assignment. The only constant available is zero. An almost matching upper bound is also obtained.

The problem of classifying all tile-k-transitive tilings of the innnite 2-dimensional ribbon (and pinched-ribbon) is shown to be solvable by classifying certain tile-k-transitive tilings of the sphere, for all k 2 N. Complete results are listed for k 3.
