Allylic Oxidation of Steroidal Compounds Using Vanadyl Acetylacetonate and Tert-butyl Hydroperoxide
(2015-07-29)
Allylic oxidation is an important reaction in steroid chemistry. Previously reported methods have various limits which do not apply when using vanadyl acetylacetonate and tert-butyl hydroperoxide. These limits include ...
A Comparative Analysis of Cyclical vs. Non-Cyclical Romantic Relationships
(2015-07-29)
Existing literature on romantic adult relationships focuses primarily on stable, married intimate dyads. However, up to 60% of couples indicate breaking up and reuniting with their partner at least once; despite their ...
Sudden Unexpected Death as a Traumatic Stressor: The Impact of the DSM-5 Revision of Criterion A for Posttraumatic Stress Disorder
(2015-07-29)
The definition of a traumatic event in Criterion A for posttraumatic stress disorder (PTSD) was narrowed in DSM-5 for events involving indirect exposure to the death of a loved one. Whereas the DSM-IV definition encompassed ...
Modulation and Control of Energy Feedback Voltage Source Inverter and Matrix Converter
(2015-07-29)
In this research work, the modulation and control of energy feedback voltage source inverters and matrix converters are investigated. This paper analyzes the basic principle of the space vector pulse width modulation ...
