This book combines game theory and complex networks to examine intentional technological risk through modeling. As information security risks are in constant evolution, the methodologies and tools to manage them must evolve to an ever-changing environment. A formal global methodology is explained in this book, which is able to analyze risks in cyber security based on complex network models and ideas extracted from the Nash equilibrium. A risk management methodology for IT critical infrastructures is introduced which provides guidance and analysis on decision making models and real situations. This model manages the risk of succumbing to a digital attack and assesses an attack from the following three variables: income obtained, expense needed to carry out an attack, and the potential consequences for an attack. Graduate students and researchers interested in cyber security, complex network applications and intentional risk will find this book useful as it is filled with a number of models, methodologies and innovative examples.

La importancia de los antioxidantes para inhibir o retardar la oxidacion de biomoleculas, aunado a los reportes de las propiedades carcinogenicas de algunos antioxidantes sinteticos, ha conducido a la identificacion y caracterizacion de compuestos naturales que presenten propiedades antioxidantes. Las algas son un grupo de organismos fotosinteticos que han desarrollado diferentes mecanismos para contender y protegerse del dano oxidativo, por lo que se les considera fuentes potenciales de compuestos antioxidantes. La diversidad bioquimica, factibilidad para su cultivo y limitada informacion sobre la eficiencia y potencialidad antioxidante de las microalgas; aunado a los efectos beneficos de los antioxidantes naturales, en la proteccion contra el dano oxidativo a constituyentes celulares, condujo a la evaluacion de las propiedades antioxidantes de extractos microalgales."
