Worms are self-replicating malicious programs that represent a major security threat for the Internet, as they can infect and damage a large number of vulnerable hosts at timescales where human responses are unlikely to be effective. Sophisticated worms that use precomputed hitlists of vulnerable targets are especially hard to contain, since they are harder to detect, and spread at rates where ...

The prevalence of antibodies to Toxoplasma gondii was conducted in 300 buffaloes from Ahvaz, Kouzestan province, south west of Iran. Blood sera were screened using a Modified agglutination test (MAT) incorporating 2-mercaptoethanol. Positive reactions in sera dilutions above 1:25 were considered as indicative for the presence of T. gondii antibodies. The overall prevalence of infection in the a...

Equimolar quantities of [WI(CO)(NCMe)(dppm)(/72-MeC2Me)][BF4] {dppm = Ph2P(CH2)PPh2} and NaSR (R = Et. Bu', Ph or CH2Ph) react in CH2C12 at room temperature to give the neutral thiolate complexes [WI(SR)(CO)(dppm)(?72-MeC2Me)] (1 —» 4) in good yield. The complex [WI(CO)(NCMe)(dppm)(?72-MeC2Me)][BF4] also reacts with two equiv­ alents of NaSR (R = Et. Bu'. Ph or CH?Ph) in CH2C12 at room temperat...

An ethical system must do two things: It must envision a particular way of life and it must work out a path to the realization of that way of life that is internally consistent, yet workable in the real world. Surprisingly, recent ecological ethics have failed to realize these two components of an ethical system. From Leopold's Land Ethic to Deep Ecology, no coherent ethical system was born. Mo...

Sophisticated worms that use precomputed hitlists of vulnerable targets are especially hard to contain, since they are harder to detect, and spread at rates where even automated defenses may not be able to react in a timely fashion. Recent work has examined a proactive defense mechanism called Network Address Space Randomization (NASR) whose objective is to harden networks specifically against ...
