Background: Today, commercial activities have become more complex and complex than in the past, and for this reason, it has become a category with more sensitivities. One of the dimensions of trade sensitivity in the present age is related to the type of allocation of trade interests and beneficiaries of these interests. In the past, only family businesses and businesses benefited from the bene...

A “complex system” is a group or organization which is made up of many interacting parts. Archetypal complex systems include the global climate, economies, ant colonies, and immune systems. In such systems the individual parts—called “components” or “agents”— and the interactions between them often lead to large-scale behaviors which are not easily predicted from a knowledge only of the behavio...

The response of complex networks to perturbations is of utmost importance in areas as diverse as ecosystem management, emergency response, and cell reprogramming. A fundamental property of networks is that the perturbation of one node can affect other nodes, in a process that may cause the entire or substantial part of the system to change behavior and possibly collapse. Recent research in meta...

Thermodynamic study on the interaction of β-CD with poly ethylene oxide and poly acrylic acid was performed by isothermal titration calorimetry at 298K. when β-CD is added to the interpolymer complex, competition is created between host-guest and Hydrogen bond. Enthalpy of interaction between the β-CD and interpolymer complex was calculated using the extended solvation theory. P=1 Shows that w...
