فاکتورهای بسیاری بر افزایش و کاهش زیست توده در جمعیت جلبک های میکروسکوپی تاثیر می گذارد. یکی از مهمترین فاکتورها میزان فسفر (ارتوفسفات) محیط کشت جلبک های میکروسکوپی است. در این مطالعه تاثیر 6 تیمار شامل BBM (Bold Basal’s Medium) بعنوان شاهد، BBM + عصاره خاک (دارای 01/0 درصد وزنی فسفر) ، BBM + 5 ، 10، 15 و 25 میلی گرم در لیتر در لیتر همگی از فسفات سدیم (Na3PO4. 12H2O) هریک بعنوان یک تیمار در ...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
in the present paper, we propose an iterative algorithm for solving the generalized $(p,q)$-reflexive solution of the quaternion matrix equation $overset{u}{underset{l=1}{sum}}a_{l}xb_{l}+overset{v} {underset{s=1}{sum}}c_{s}widetilde{x}d_{s}=f$. by this iterative algorithm, the solvability of the problem can be determined automatically. when the matrix equation is consistent over...
in this paper, we investigate the generalizedhyers--ulam stability of the functional equation
in this paper we obtain exact solutions of the generalized kuramoto-sivashinsky equation, which describes manyphysical processes in motion of turbulence and other unstable process systems. the methods used to determine the exact solutions of the underlying equation are the lie group analysis and the simplest equation method. the solutions obtained are then plotted.
In this paper, the modified simplest equation method is successfully implemented to find travelling wave solutions of the generalized forms $B(n,1)$ and $B(-n,1)$ of Burgers equation. This method is direct, effective and easy to calculate, and it is a powerful mathematical tool for obtaining exact travelling wave solutions of the generalized forms $B(n,1)$ and $B(-n,1)$ of Burgers equation and ...
The unsmooth boundary will greatly affect motion morphology of a shallow water wave, and a fractal space is introduced to establish a generalized KdV-Burgers equation with fractal derivatives. The semi-inverse method is used to establish a fractal variational formulation of the problem, which provides conservation laws in an energy form in the fractal space and possible solution structures of t...
