Insomnia is often described as subjective complaint of poor sleep quality or quantity despite adequate time for sleep. Insomnia results in daytime fatigue, irritability and decreased concentration and is often associated with other diseases such as psychiatric disorders (e.g. anxiety conditions), medical disorders or substance abuse. Anxiety also leads to fatigue, irritability and decreased concentration. Several forms of anxiety are known, such as generalized anxiety disorder, panic disorder, social anxiety disorder and post-traumatic stress disorder. Effective treatment of said conditions thus positively influences day-to-day life of patients suffering from such conditions.Current pharmaceuticals used for the treatment of insomnia and anxiety comprise benzodiazepines, benzodiazepine-receptor agonists, melatonin-receptor agonists as well as antidepressants.

This very economical process gives high yields and displays a long life of the catalyst used, simple isolation of the product and low energy consumption. The 2-butanol used for the ...

A Plasma Arc Reformer for creating a useful fuel, such as Methanol, using any of Methane, Municipal Solid Waste, farm or forest waste, coal orchar rock from oil shale production, petrochemical hydrocarbons, (any carbon containing charge), water, and/or Municipal Sewage, as the source material. A High temperature Plasma Arc de-polymerizes the source material into atoms which, upon partial cooling, creates a gas stream rich in CO and H 2 (syngas). Subsequent molecular filter and catalyst stages in the system remove contaminants and produce the output fuel. The system is closed loop with regard to the syngas production in that it recycles the residual unconverted gas and even the exhaust gases if desired. The large amount of heat produced is captured and converted to electric power using a supercritical CO 2 Rankin cycle resulting in potentially high efficiencies.
