Anxiety disorders are estimated to affect 26.9 million individuals in the United States at some point during their lives. This study used the human capital approach to estimate the direct and indirect costs of these highly prevalent disorders. In 1990, costs associated with anxiety disorders were $46.6 billion, 31.5% of total expenditures for mental(More)
Obsessive-compulsive disorder (OCD), classified as a severe mental illness by the National Advisory Mental Health Council, affects 2.1% of the population annually, as shown by the Epidemiological Catchment Area surveys. This study, using the human capital approach, estimated the direct and indirect costs of OCD. The total costs of OCD were estimated to be(More)
Random drug testing in the workplace has become more common since federal guidelines were issued in 1988, despite the criticism that most positive tests are the result of occasional use of illicit drugs. In order to determine the relative probabilities of detecting frequent versus infrequent users of illicit drugs, a survey of 15 experts in the drug abuse(More)
We have investigated the static and dynamic characteristics of high voltage lateral power diode (L-Diode) on silicon-oninsulator (SOI) substrate with planar / trenched buried oxide (Box) layer on the basis of device simulations. The conduction loss of the conventional L-Diode with planar Box layer is found to be reduced as a result of improving blocking(More)
The quantity of D-malate was determined using apparatus comprised of a reactor with immobilized D-malate dehydrogenase (D-MDH) in a flow line. NADH formed by an enzymatic reaction was fluorometrically detected. The optimal concentration of NAD in the carrier was determined. The maximum peak areas due to NADH were observed at pH 8.0 when the pH of the(More)
