چکیده

Objectives: Cancer which is one of the most challenging health problems overall world composed various processes: tumorigenesis, angiogenesis, and metastasis. Attempting to understand truth behind this complicated disease common objectives many experts researchers from different fields. To provide deeper insights any prognostic and/or diagnostic scientific contribution topic so crucial. In study, avascular tumor growth model earliest stage taken into account a mathematical point view. The main aim solve numerically. 
 Methods: This study has focused on numerical solution continuum described by Sharrett Chaplin. Unlike existing recent literature, methods for temporal domain. obtain schemes central difference method been used in spatial coordinates. discretization technique reduced partial differential equation an ordinary will be solved successively two alternative techniques: 4th order Runge-Kutta (RK4) three-stage strongly-stability preserving (SSP-RK3). Results: proposed methods. results are discussed both biological angles. compatibility depicted figures. Besides outputs, accuracies have listed Furthermore, rate convergence also computationally.
 Conclusion: All recorded evidence that applicable solving such models. Moreover, all exhibited figures proved It observed quiescent cells mysterious clinics tend become proliferative selected parameters.

Two Dimensional Mathematical Model of Tumor Angiogenesis: Coupling of Avascular Growth and Vascularization

Introduction As a tumor grows, the demand for oxygen and nutrients increases and it grows further if acquires the ability to induce angiogenesis. In this study, we aimed to present a two-dimensional continuous mathematical model for avascular tumor growth, coupled with a discrete model of angiogenesis. Materials and Methods In the avascular growth model, tumor is considered as a single mass, wh...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
