in this article, a speed control of dc motor is designed and illustrated using fuzzy logic-based programmable logic controller (plc). the dc motor is an attractive part of electrical equipment in many industrial applications requiring variable speed and load specifications due to its ease of controllability. the designed system is consisted of three main parts including programmable logic contr...

the purpose of this current study was to investigate the influence of perceptual-motor trainings on motor skills of girls with trainable mental retardation. so 20 girls with trainable mental retardation in the town of marivan welfare organization with the average of 8/3 ±1/11 years and iq of 39/14±6/84 with purposive sampling method were studied. all girls were pretested. then samples based on ...

objective(s)previous studies have shown that vitamin b as well as folate supplementation has been implicated in cognitive and neurodegenerative disorders including alzheimer’s and parkinson's diseases. the aim of present study was to evaluate the effects of folic acid on passive avoidance task and motor coordination in healthy adult male rats.materials and methodsanimals were randomly divi...

background and objective: achievement of motor skills is an important part of childhood development. there are some scales that commonly used for preschool-aged children including peabody developmental motor scales, 2nd edition (pdms-2). a cross sectional study designed to compare motor skills of high risk and normal infants of 3 to 6 months of age. methods: in this case control study, 45 high ...

objectives: developmental coordination disorder (dcd) is a motor skill disorder which impacts upon a child, s ability to perform age-appropriate activity of daily living and academic performance. they have problems in gross & fine motors, their upper limb coordination are impaired, too. in this way, we decided to compare motors skills with botmp test in children with dcd and their normal peers....

background and objective: as apoptotic cell death is extremely involved in physiological development and many pathological situations such as cancer and neurodegenerative diseases, the understanding of its molecular machinery can be useful in designing new therapeutic strategies. the present study investigated the temporal expression of the proapoptotic protein bax in adult spinal motoneurons. ...

an internal ballistics model has been developed for performance prediction of a solid propellant rocket motor. inthis model a 1-d unsteady euler equation with source terms is considered. the flow is assumed as a non-reacting mixture of perfect gases with space and time varying thermo physical properties. the governing equations in the combustion chamber are solved numerically by using the stege...

single-phase squirrel cage and three-phase induction electromotors are the most popular electromotors used in industry from long ago. when an induction motor starts with direct connection method, it takes a lot of current from the power supply (several times the nominal current); so, several methods have been devised to start such electromotors. these methods either reduce the voltage of the st...
