let $g$ be a group and $aut(g)$ be the group of automorphisms of‎‎$g$‎. ‎for any natural‎‎number $m$‎, ‎the $m^{th}$-autocommutator subgroup of $g$ is defined‎‎as‎: ‎$$k_{m}(g)=langle[g,alpha_{1},ldots,alpha_{m}] |gin g‎,‎alpha_{1},ldots,alpha_{m}in aut(g)rangle.$$‎‎in this paper‎, ‎we obtain the $m^{th}$-autocommutator subgroup of‎‎all finite abelian groups‎.

objective(s): the aim of study was to determine history of genitourinary diseases in war related bilateral lower limb amputees who were injured during iran-iraq war (1980-1988).   methods: subjects with war related bilateral lower limb amputation (335 persons) were examined by two physicians for any history of genitourinary diseases and their documents were reviewed.   results: the mean age was...

abstract objectives: the purpose of this study was to investigate the relationship between core stability and lower extremity injuries in female athletes through functional tests. decreased core stability has been suggested to contribute to the etiology of lower extremity injuries. so far researches had been used non-functional tests to assess the core stability. material and methods: fifty col...

The mechanism of the human moving in water relies on the mutual impact of particular segments of the locomotion system. The essence of a small child locomotion in water is not developing speed, but primarily maintaining on the water surface and crossing the longest possible distance [1]. The subject of this work is the time and space analysis of the locomotion cycle of the infants’ lower limb d...

This investigation examined the premise derived from recent reports, that children who are consistent right-handers are better coordinated than their left- and mixed-sided (inconsistent) peers. The observation of limb laterality was extended to include footedness. Two samples of children (N = 273) (foot laterality/hand laterality), matched for age and sex, were assessed for motor proficiency an...
