Cryptographic systems are used for secure communications in the government, in industry, and by individuals. Many cryptographic systems base their security on our inability to factor quickly. For this reason, in the last few decades several fast factoring algorithms have been developed. The Quadratic Sieve is one of the best...
The majority of bacteria suspended in seawater do not appear to be metabolically active or in good physiological condition as assessed by various methods. We tested the idea that a large fraction of ‘inactive’ bacterial cells can become ‘active’ with respect to detectable cell-specific electron transport system (ETS) activity, determined...
The redox dye 5-cyano-2, 3-ditolyl tetrazolium chloride (CTC) is used in aquatic sciences as a vital stain for enumeration of respiring bacteria in situ. Questions concerning its efficacy have been raised. We propose that the abundance of CTC-positive (CTC+) bacteria is a useful parameter in microbial ecology based on the...
