Induction heating coupler

An induction heating device includes a handle having a hollow interior and two opposite ends, a wrist connected to one end of the handle, a U-shaped pole piece having two spaced apart ends, a tank circuit including an induction coil wrapped around the pole piece and a capacitor connected to the induction coil, a head connected to the wrist and including a housing for receiving the U-shaped pole piece, the two spaced apart ends of the pole piece extending outwardely beyond the housing, and a power source connected to the tank circuit. When the tank circuit is energized and a susceptor is placed in juxtaposition to the ends of the U-shaped pole piece, the susceptor is heated by induction heating due to magnetic flux passing between the two ends of the pole piece

Mediators and Moderators of Parental Involvement on Substance Use: A National Study of Adolescents

Current social developmental theories of drug use often incorporate mediation processes, but it is generally unknown whether these mediation processes generalize across ethnicity and gender. In the present study, we developed a mediation model of substance use based on current theory and research and then tested the extent to which the model was moderated by gender and ethnicity (African American, European American, and Hispanic American), separately for 8th and 10th graders. The respondents were adolescents from the 1994, 1995, and 1996 cohorts of the Monitoring the Future (MTF) project, which conducts yearly in-school surveys with nationally representative samples. Multi-group, structural equation modeling (SEM) results indicated much similarity across gender and ethnicity for school success and time spent with friends as partial mediators of risk taking and parental involvement on drug use (controlling for parental education). However, there were some differences in the magnitude of indirect effects of parental involvement and risk taking on substance use for 8th-grade African American girls. Discussion focuses on the potential success of prevention efforts across different ethnicities and gender that target parent–child relationship improvement and risk taking, and considers possible culture- and gender-specific issues.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45503/1/11121_2005_Article_19.pd
