New digital media (e.g., the Internet, text messaging, and social networking sites [SNS]) have dramatically altered the communication landscape, especially for youth. These communication platforms present new tools for engaging youth in sexual health promotion and risk reduction. We searched eight public databases across multiple disciplines for all(More)
OBJECTIVE This study verified the surface microroughness of denture acrylic resins submitted to toothbrushing, chemical disinfection and thermocycling procedures. MATERIAL AND METHODS Samples were prepared according to conventional, microwaved and boiled resins and submitted to microroughness measurements before and after procedures using a profilometer(More)
Each year, approximately 3000 pregnancies in the United States are affected by neural tube defects (NTDs), serious birth defects of the brain and spine. Daily periconceptional consumption of folic acid can reduce the incidence of NTDs by 50%-70%. This study was designed to understand Latina mothers' folic acid awareness, knowledge, and behaviors and to(More)

Young Latina adults require targeted health messages to meet the unique needs of this life stage. Folic acid messages for the prevention of neural tube defects that are effective for other women might not be relevant to this group. The aim of this study was to identify barriers and motivators to folic acid consumption for this population and develop(More)
To facilitate a rapid response to the International Linear Collider (ILC) L-band development program at SLAC, a spare converter-modulator was shipped from LANL. This modulator was to be a spare for the Spallation Neutron Source (SNS) accelerator at ORNL. The ILC application requires a 33% higher peak output power (15 MW) and output current (120 Amp). This(More)
The aim of this study is to investigate the effect of the toothbrushing, chemical disinfection and thermocycling treatments on the surface hardness of acrylic resins used for denture bases. The Classico (conventional), Onda Cryl (microwaved) and QC-20 (boiled) thermoactivated acrylic resins were used to prepare specimens. Prior to and after cleaning(More)
OBJECTIVES The purpose of this study was to evaluate the effect of flask-closure methods, post-pressing times and acrylic resins on denture base adaptation. MATERIALS AND METHODS The resins were flasked using a hydraulic press and closed with the traditional clamp or RS system. Conventional heat-cure resin was polymerised immediately or at 6 h(More)
