Proposed Idea for Steganography Assignment

The idea behind this technique is to utilize the presence of punctuation marks like , ; : “ etc. in the text for encoding a secret message. The secret message to be communicated will be hidden in any piece of text through binary encoding of punctuation marks. Two punctuation marks can be used to represent binary data or several punctuation marks can be used to represent binary combinations. The...

Chemical contamination of water supplies.

Man-made organic chemicals have been found in drinking water for many years. Their numbers and varieties increase as our analytical capabilities improve. The identified chemicals comprise 10 to 20% of the total organic matter present. These are volatile or low molecular weight compounds which are easily identified. Many of them are carcinogenic or mutagenic. Chlorinated compounds have been foun...

Climate change. Threats to water supplies in the tropical Andes.

to emphasize those measurements of our local astrophysical laboratory that will best illuminate how these fundamental cosmic entities operate. Moreover, observations to date already indicate that the Saturn system is literally changing before our eyes. We anticipate that even more dramatic transformations in our neighborhood's astrophysical laboratory will be monitored by Cassini's instruments ...

Bacterial nitrification in chloraminated water supplies.

Nitrifying bacteria were detected in 64% of samples collected from five chloraminated water supplies in South Australia and in 20.7% of samples that contained more than 5.0 mg of monochloramine per liter. Laboratory experiments confirmed that nitrifying bacteria are relatively resistant to the disinfectant. Increased numbers of the bacteria were associated with accelerated decays of monochloram...
