The dynamic strength index (DSI) is a useful tool to assess an athlete's capacity effectively use maximum during tasks. Although DSI traditionally calculated based on peak forces, the ability express force over time (i.e., impulse) better predictor of performance. purpose this study was investigate association between (fDSI) and impulse (iDSI). Nineteen female collegiate lacrosse players perfor...

abstract in this paper, markov chain and dynamic programming were used to represent a suitable pattern for tax relief and tax evasion decrease based on tax earnings in iran from 2005 to 2009. results, by applying this model, showed that tax evasion were 6714 billion rials**. with 4% relief to tax payers and by calculating present value of the received tax, it was reduced to 3108 billion rials. ...

abstract background: various types of foot orthoses are prescribed for people with flatfoot. it has been reported that orthoses not only improve the biomechanics of the lower limb, but also have good effects on some balance parameters in these subjects. it is hypothesized that the latter effect is dependent on the rigidity of the orthoses. the aim of this study was to evaluate and compare the e...

OBJECTIVE To evaluate the dynamic filling index, a novel parameter to monitor changes in venous return and drainable volume, in circulatory assisted patients. Minimized extracorporeal bypass systems lack volume buffering capacity, demanding tight control of drainable volume to maintain bypass flow. Therefore, with patients on minimized bypass quantitative assessment of venous drainable volume i...
