Measurement of gross alpha, gross beta activities and cosmogenic beryllium-7 (7Be) concentrations were made both daily and weekly during the years 2001--2004 from samples of atmospheric aerosols filtered from the air at Tehran Nuclear Research Center (35 41' N) and Zahedan (28 29' N). Weekly aerosol samples collected with the high-volume air samplers on cellulose filters were used to determine ...

Uranium is a regulated contaminant (maximum level [MCL] 30 μg/L) that contributes to the gross alpha activity of groundwater. The adjusted (MCL 15 pCi/L) determined by subtracting total uranium from measured activity. U.S. water utilities can use mass-based and radiochemical analysis methods for compliance monitoring uranium. Mass-based measurements conversion factor 0.67 pCi/μg calculate This ...

The purpose of this study was to examine the effects of visual supports on the performance of the Test of Gross Motor Development (TGMD-2) for children with autism spectrum disorder (ASD). Participants (N = 22) performed the TGMD-2 under three different protocols (traditional protocol, picture task card protocol, and picture activity schedule protocol). Gross motor quotient scores on the TGMD-2...

OBJECTIVE The objectives of this study were a) to develop a physical activity program for nursery schools, and b) to evaluate the effects of this program on fundamental movement skills of preschool age children in Iran. METHODS In this quasi-experimental study 147 children from five nursery schools in five different cities in Iran were enrolled. A physical activity program was developed for n...

One important determinant of childhood physical activity and sedentary behavior may be that of motor development in infancy. The present analyses aimed to investigate whether gross and fine motor delays in infants were associated with objective and self-reported activity in childhood. Data were from the UK Millennium Cohort Study, a prospective cohort study, involving UK children born on or aro...

Muhammad Abstract— The conditions to measure the gross beta radioactivity in water samples from the permanent site of Usmanu Danfodiyo University Sokoto in Sokoto State Nigeria were established. The gross beta radioactivity of water samples were measured using proportional gas counter. The result show that the gross beta radioactivity in mo...
