let g be a group. a subset x of g is a set of pairwise noncommuting elements if xy ̸= yx for any two distinct elements x and y in x. if |x| ≥ |y | for any other set of pairwise non-commuting elements y in g, then x is said to be a maximal subset of pairwise non-commuting elements. in this paper we determine the cardinality of a maximal subset of pairwise non-commuting elements in any non-abelian...

background: ammonium is produced in culture medium due to amino acids degradation and has adverse effect on in vitro culture of embryo. in the current study, the purpose was to evaluate the effects of ammuniom chloride (ac) on in vitro oocyte maturation rate and early embryo development in the sheep and its effect on the expression of bcl-2. methods: in vitro maturation (ivm) was performed in t...

objective(s): comparative in vivo studies were carried out to determine the adsorption characteristics of amitriptyline (amt) on activated charcoal (ac) and sodium polystyrene sulfonate (sps). ac has been long used as gastric decontamination agent for tricyclic antidepressants and sps has showed to be highly effective on in-vitro drugs adsorption. materials and methods: sprague-dawley male rats...

Background & Aims: Acute acromioclavicular (AC) joint dislocation is common in shoulder injuries. Considering the biomechanics of this joint, the use of a treatment method, which can restore joint physiology and biomechanics to the extent possible, is important. This study aimed to compare the treatment of acute AC joint dislocation by screw fixation with and without ligament reconstruction. Me...

results the tlr3 protein in the ach group tended toward reduction although the p value of the comparison between the ach group and hd group was not statistically significant. the tlr3 levels in the hcc, ac, and cir groups were higher than those in the hd and ach groups. tlr3 was not interrelated with all costimulation proteins in the dcs and t cells in all five groups. no group presented any in...

The work presented in this paper proposes an approach to reduce the common mode voltage at the output of matrix converters when a direct torque control scheme is employed to drive a permanent magnet synchronous motor. A mathematical analysis of the common mode voltage at the output of matrix converters is firstly carried out which is then corroborated by simulation results. Based on this analys...
