Reflection and transmission of plane waves between two initially stressed thermoelastic half-spaces with orthotropic type of anisotropy is studied. Incidence of a SV-type wave from the lower half-space is considered and the amplitude ratios of the reflected and transmitted SV-wave, P-wave and thermal wave are obtained by using appropriate boundary conditions. Numerical computation for a particu...

Background: Sodium valproate (SV) has been approved for migraine prophylaxis and its intravenous form is used to treat acute migraine attacks. We compared the efficacy and safety of intravenous SV and subcutaneous Sumatriptan in managing acute migraine attacks. Methods: This double-blind randomized clinical trial divided 90 patients into two groups: one group received 400 mg of intravenous SV a...

conclusions in our patients, the ra grafts had an acceptable patency rate in 2 to 5 years’ follow-up. although the sv grafts had a relatively higher patency rate than ra grafts in our asymptomatic patients, the patency rates in ra and sv grafts were close to each other. the ra graft function was poor in the patients with a higher number of risk factors and in the females. background patency of ...

BACKGROUND Few studies have examined parental perceptions of their child's screen-viewing (SV) within the context of parental SV time. This study qualitatively examined parents' perceptions of their 5-6-year-old child's SV within the context of their own quantitatively measured SV. METHODS A mixed-methods design employed semi-structured telephone interviews, demographic and SV questionnaires,...

OBJECTIVE This study aimed to investigate total and device-specific screen viewing (SV) and its determinants in children aged 2 years and below. DESIGN Cross-sectional study conducted in February 2014. SETTING Well-child clinics in Singapore national polyclinics. PARTICIPANTS Parents of children (Singapore citizens or permanent residents) aged 2 years and below were enrolled during routin...
