For Corporations, innovative technology insures continued market leadership; for Governments, it remains the metric of capability, defining superiority.
During the first six years in Chicago, MRX was structured as an efficient global corporation based on models from the Pritzker Organization and Intelligence Agencies. Studying everything specific to Aristotle Onassis provided the "street smarts" and the harsh realities of successful international negotiations. Dr. Robert Beyster provided the corporate model for the optimum performance from every employee. The Global Corporate Structure of MRX is an augmented derivative of the Pritzker, Onassis, Intelligence Agencies, SAIC and Leidos models. MRX Technologies MRX Technologies provides global scientific, engineering, systems integration, technical services and advanced technological solutions to all branches of the U.S. Military, the Department of Defense, the Department of Energy, the State Department, the Diplomatic Community, Intelligence Agencies, the U.S. Department of Homeland Security and other U.S. Government Civil Agencies, as well as solving complex technical challenges requiring innovative solutions for customers in selected international commercial markets.

A significant number of Heads of State representing oil producing Countries have attempted to hide their individual personal wealth in excess of $300B USD. ($300,000,000,000.00) A large amount of this total wealth is comprised of US $100 Bills. This cash enables high levels of corruption. Surveillance of one oil producing Country's Head of State provided the evidence he was expecting to collect over $100B in one year when oil was at $115 per barrel.

The process called Surface Enhanced Raman Scattering (SERS), scatters laser light from a sample that has been combined with silver nanoparticles. It can fingerprint more than one bacterium at a time, allowing treatment to then be targeted.Dr. Karen Faulds, a reader in the department of pure and applied chemistry at Strathclyde university, said: "Essentially what you do is shine a laser beam at the molecule and measure the shift in wavelength."This gives you a fingerprint - what you call a vibrational spectrum. "And you can definitively identify that molecule."The Strathclyde researchers said their test could be applied to any kind of pathogen that contains DNA, like fungi or viruses.
