Screen time during the preschool years is detrimental to wellbeing. The impact of parental perceptions on preschoolers' screen time is unknown. This paper explores the association between maternal perceptions of the impact of screen time on their preschoolers' wellbeing with their child's screen time and the potential mediating role of their perception of the appropriate amount of screen time. ...

the use of mammography film-screen is limited in general radiography. the purpose of this study was to compare the effectiveness of mammographic film-screen and standard film-screen systems in the detection of small bone fractures. radiographs were taken from patients' extremities and neck areas using mammography film-screen and standard film-screen (n=57 each). fourteen other radiographs were ...

This article is focused on the determination of lidocaine hydrochloride as a local anaesthetic drug. A potentiometric method based on modified screen-printed and modified carbon paste ion-selective electrodes was described for the determination of lidocaine hydrochloride in different pharmaceutical preparations. It was based on potentiometric titration of lidocaine hydrochloride using modified ...

BACKGROUND Preschool children can spend up to 12 h a day in sedentary time and few meet current recommendations for screen time. Little is known about ecological correlates that could be targeted to decrease specific versus total sedentary behaviour. This study examined whether the correlates of screen time and sedentary time differ in preschool boys and girls. METHODS Parents participating i...

BACKGROUND Much attention has been paid to adolescents' screen time, however very few studies have examined non-screen sedentary time (NSST). This study aimed to (1) describe the magnitude and composition of screen sedentary time (SST) and NSST in Australian adolescents, (2) describe the socio-demographic correlates of SST and NSST, and (3) determine whether screen time is an adequate surrogate...
