pah ها هیدروکربن های آروماتیکی هستند که از دو یا چند حلقه بنزنی تشکیل شده اند. این ترکیبات دارای منشا انسانی و طبیعی می باشند و بدلیل گستردگی حضور، پایداری، قابلیت تجمع زیستی و فعالیت سرطانزایی به یک نگرانی مهم زیست محیطی تبدیل شده اند. گرچه pahها دستخوش فرآیند های جذب سطحی، تبخیر، تجزیه نوری و تجزیه شیمیایی می شوند اما تجزیه میکروبی اصلی ترین فرآیند حذف این ترکیبات از محیط است. در کشورهای رو ب...

In this investigation, a bi-linear shear deformable shell element is developed using the absolute nodal coordinate formulation for the large deformation analysis of multibody shell structures. The element consists of four nodes, each of which has the global position coordinates and the gradient coordinates along the thickness introduced for describing the orientation and deformation of the cros...

Considering the structure effect of tunnel stability in western mining of China, three typical kinds of numerical model were respectively built as follows based on the strain softening constitutive model and linear elastic-perfectly plastic model for soft rock and interface: R-M, R-C(s)-M and R-C(w)-M. Calculation results revealed that the stress-strain relation and failure characteristics of t...

We predict planar Sb/Bi honeycomb to harbor a two-dimensional (2D) topological crystalline insulator (TCI) phase based on first-principles computations. Although buckled Sb and Bi honeycombs support 2D topological insulator (TI) phases, their structure becomes planar under tensile strain. The planar Sb/Bi honeycomb structure restores the mirror symmetry, and is shown to exhibit non-zero mirror ...

in this paper, we introduce and study the prime, strongly prime,semiprime and irreducible fuzzy bi-ideals of a semigroup. we characterize thosesemigroups for which each fuzzy bi-ideal is semiprime. we also characterizethose semigroups for which each fuzzy bi-ideal is strongly prime.

An indicator variable was developed that may be used to visualize and detect bi–directionality in wind tunnel strain–gage balance calibration data. First, the calculation of the indicator variable is explained in detail. Then, an empirical criterion is proposed that may be used to decide which load components of a balance have bi–directional behavior. The criterion could be used, for example, t...
