Chemical composition of the essential oils extracted from the leaves, stems, flowers and seeds of  Heracleum rechingeri Manden. were analyzed by GC and GC/MS. Twenty-four components were characterized for the leaf oil with Octyl acetate(47.2%), Octanol(15.2%) and E-caryophyllen (5.7%) as the main constituents. 25 compounds were identified in the stem oil with Elemicin (65.3%), Octyl acetate (13...

sedan passenger-cars are known today as one of the most popular industrial products. since the advent of the first samples by henry ford and karl benz ever, classification and recognition of passenger-cars have been based on the set of technical standards or experimental criteria and have not been from the point of view of designers and stylists who focus on content of form and visual aesthetic...

Vehicular Ad-Hoc Networks (VANETs) is a novel technology that has recently emerged and due to its swift changing topology and high mobility nature, it has become problematic to design an efficient routing protocol in VANETs’ amongst both moving and stationary units. Also, the existing routing algorithms are not very effective to satisfy all requirements of VANETs. This paper explores the need o...

reduced differental transform method (rdtm), which isone of the useful and effective numerical method, is applied to solve nonlinear time-dependent foam drainage equation (fde) with different initial conditions. we compare our method with the famous adomian decomposition and laplace decomposition methods. the obtained resultsdemonstrated that rdtm is a powerful tool for solving nonlinear par...
