The concentrations of methaqualone and 6-hydroxy-methaqualone in urine samples were analyzed by isotope dilution analysis and field ionization mass spectrometry. Analyses performed on samples collected over an 11 day period following drug ingestion show that these compounds are excreted with halflives of approximately 50 hr. Detection of the metabolite up to one month after ingestion of the drug is possible. The sensitivity of the technique has been increased by using higher purity carrier compounds and more thorough extraction and purification procedures. The present limit of detection of drugs is approximately 10 to the minus 10th power g/ml.

This report examines how China’s development of the IoT—bolstered by the Chinese government’s efforts to harness national resources for its promotion—has put China in a position to credibly compete against the United States and other leaders in the emerging IoT industry. China’s pursuit of IoT dominance constitutes a significant challenge to U.S. economic and national security interests. Its robust participation in international standards committees has given Beijing greater opportunities to dictate the rules of the road. Its research into IoT security vulnerabilities and its growing civil-military cooperation raise concerns about gaining unauthorized access to IoT devices and sensitive data. Its authorized access to the IoT data of U.S. consumers will only grow as Chinese IoT companies leverage their advantages in production and cost to gain market share in the United States.
