abstract   introduction: balance is one of the most important contexts in ageing. improving balance in middle age can prevent falling down in elderly which impose the financial and mental costs to society. imbalance between dominant and non-dominant leg can lead to some problems. that’s way; studying effects of similar exercise on dominant and non-dominant legs of body can prevent problems caus...

the concept of imagery is to make an image of successful movement skill or a relaxing image in mind with no body training and external experience. the aim of the present study was to compare the effect of traditional and pettlep mental imagery methods on static and dynamic balance. the statistical population consisted of all female university of tehran students who had general physical educatio...

objective:more similarity to in vivo medium may help to increase the proliferation and differentiation of cells at in vitro condition. the present study has investigated the effect of a dynamic mediumand nano hydroxyapatite (nha) presence on proliferation and differentiation of mesenchymal stem cells (mscs) to bone cells using electrospun polycaprolactone (pcl) scaffolds. methods: we prepared p...

automobile body plays crucial role in preventing the collision energy transfer in severe accidents to the passengers. if the collision energy is dissipated or saved in bumper or chassis, the amount of damage to the occupants would be minimized. using novel laminated panel (fiber metal laminate) in auto body, and considering the characteristics such as high energy absorption, strength, high dent...

although in recent two decades, the concept of dielectric barrier discharges (dbds) have been developed in ozone production well, air pollution control, plasma screens and control of chemical, and biological and medical processes, employment of this concept for high voltage applications to improve insulation performance as an alternative to the pressurized gas-insulated systems (gis) utilizing ...

in this paper, full scale load test of a horizontally curved steel box-girder bridge is carried out in order to detect structural defects, which reportedly result in unwanted vibrations in nearby buildings. the bridge is tested under the passage of six heavy vehicles at different speeds, so as to determine its static and dynamic responses. a total number of one hundred and two (102) sensors are...

The dynamic and static deficit (DDI, SDI), partial root drying (DPRD, SPRD) and full (FI)irrigation strategies were applied in Agria and Ramos potato cultivars in a semi-arid area. FIreceived 100% of the potential evapotranspiration (ET); SDI and SPRD received 75% of ETduring the growth period; DDI and DPRD received 90% of ET in the first third, 75% of ET inthe second third and 50% of ET in the...
