a motor vehicle seat belt use law for the driver and front-seat passenger was implemented in taiwan on june 1, 2001. the purpose of this study was to determine the effect of motor vehicle seat belt use on the severity of traumatic brain injuries because of motor vehicle accidents.data were collected from 27 major teaching hospitals four years before june 1, 2001 and until may 31, 2013. a total ...

production ofdimethyl amino ethanol (dmae) and effective parameters on efficiency and purity of the chemical were studied in this article. dimethylation of ethanol amine using aqueous formaldehyde in the presence of formic acid was applied for production of dmae. results showed that four parameters such as outlet temperature of co2 gas, reflux temperature, reflux time and extraction solvent wer...

Today, often ankle’s active prosthesis is used for transtibial amputated people’s walking, because these prostheses have some advantages such as increasing power and decreasing metabolism. In most of active prosthesis in order to create a movement or increase the force at the push-off, electrical actuators are used like a motor. In cases where a higher-power motor is necessary, the capacity, we...

Inspired by the discovery of dimeric motor proteins capable of undergoing transportation in living cells, significant efforts have been expended recently to the fabrication of track-walking nanomotors possessing two foot-like components that each can bind or detach from an array of anchorage groups on the track in response to local events of reagent consumption. The central problem in fabricati...

background and objectives: motor development is considered as a part of the process of growth and development in which the child, firstly gains control over his own body function, and then utilizes it for interaction and manipulation with the environment. the aim of this study was to standardize of peabody developmental motor scale (pdms) in normal children aged 72 to 83 months living in tehran...

Nucleate boiling heat transfer coefficients may be strongly reduced by scale formation, even for conditions where the bulk foulant concentration is well below the saturation concentration. Due to the mechanism of micro-layer evaporation, the local concentration at the heat transfer surface can be considerably increased, causing the formation of scale and changes in bubble frequency and bubble d...

the aim of this study was to investigate the effect of perceptual-motor and music enrichment of environment on the development of fine and gross motor movements in infants. 32 healthy infants (5 to 8 months old) participated in this study and were divided homogenously into four groups (each group 8 subjects): three experimental groups and one control group. experimental groups had 36 training s...
