the aim of this study was to estimate body fat percentage through circumference of different parts of body by hydrodensitometry (hydrostatic underwater weighing) as the criterion method and to develop related equations. 158 male students of isfahan university (mean age: 21.6 yrs, height: 174 cm, weight: 69.04 kg, body fat percentage: 15.61 kg, bmi: 22.59) were randomly selected. these subjects ...

We consider the occurrence of record-breaking events in random walks with asymmetric jump distributions. The statistics of records in symmetric random walks was previously analyzed by Majumdar and Ziff [Phys. Rev. Lett. 101, 050601 (2008)] and is well understood. Unlike the case of symmetric jump distributions, in the asymmetric case the statistics of records depends on the choice of the jump d...

plexus injury. Few studies report the rate of revision surgeries following free functional muscle transfers. We examinedthe reoperation rate and indication for reoperation after primary reconstruction of upper extremity function with a freegracilis transfer after brachial plexus injury.Methods: From 2003-2016, we identified 25 patients who underwent a free functional gracilis ...

In this article, to study the effect of pulse-type near-fault earthquakes on the seismic demands of steel moment frames, 15-story 2D-frame was analyzed under the influence of 20 near-fields with forward directivity effect and 2 far-field records. The relationship between Effective Cyclic Energy, ECE and displacement demands, velocity and hysteretic curve of SDOF systems in two near- and far-fau...

This paper studies three graph problems with parameters n, the number of nodes, e, the number of edges, and k, the diameter of the graph. Given any two of these three parameters, the problem is to construct a directed graph which minimizes or maximizes the third. The first problem has its origin in a recent study of record allocation in a paged computer system. It is shown how to construct grap...

A total of360 Iranian combatants who were exposed to mustard gas by the Iraqi forces in the war fronts were studied. Acute effects and gastrointestinal (GI) complications of sulfur mustard (S M) intoxication were studied separately in Iranian combatants admitted to Imam Reza Hospital from January 1984, to May 198X, In order to record the clinical and paraclinical findings, a special examina...
