Abstract:

Marine natural products have attracted the attention of scientists to isolate novel biologically active metabolites. Several promising metabolites were discovered from marine sponges with different biological activities including antimicrobial and anticancer. By far, more than 36% of the metabolites discovered from marine organisms were isolated from sponges. In this study, the alkaloids isolated from marine sponges with antimicrobial activity were described.

Qaralleh, I. (2016). On Dynamics of a class taken from Quadratic Stochastic Operators. Journal of Basic and Applied Research, 2(1): 8-12

Abstract:

The Quadratic dynamical systems considered as an important source of analysis for the study of dynamical properties and modeling in various fields. A quadratic stochastic operator (in short QSO) is usually used to present the time evolution of species in biology. The general problem in the nonlinear operator theory is to study the behavior of operators. This problem was not fully finished even for quadratic stochastic operators which are the simplest nonlinear operators. To study this problem, several classes of QSO were investigated. In this paper we investigate the dynamics of three classes of such operators.
