The soil is the medium through which pollutants originating from human activities, both in agriculture and industry, move from the land surfaces to groundwater. Polluting substances are subject to complex physical, chemical and biological transformations during their movement through the soil. Their displacement depends on the transport properties of the water-air-soil system and on the molecular properties of the pollutants. Prediction of soil pollution and restoration of polluted soils requires an under standing of the processes controlling the fate of pollutants in the soil medium and of the dynamics of the contaminants in the un saturated zone. Our book was conceived· as a basic overview of the processes governing the behavior of pollutants as affected by soil constituents and environmental factors. It was written for the use of specialists working on soil and unsaturated zone pollution and restoration, as well as for graduate students starting research in this field. Since many specialists working on soil restoration lack a back ground in soil science or a knowledge of the properties of soil pollutants, we have included this information which forms the first part of the book. In the second part, we discuss the partitioning of pollutants between the aqueous, solid and gaseous phase of the soil medium. The retention, transformation and transport of pollutants in the soils form the third section.
Complex and controversial, hackers possess a wily, fascinating talent, the machinations of which are shrouded in secrecy. Providing in-depth exploration into this largely uncharted territory, Profiling Hackers: The Science of Criminal Profiling as Applied to the World of Hacking offers insight into the hacking realm by telling attention-grabbing tales about bizarre characters that practice hacking as an art. Focusing on the relationship between technology and crime and drawn from the research conducted by the Hackers Profiling Project (HPP), this volume applies the behavioral science of criminal profiling to the world of internet predators. The authors reveal hidden aspects of the cyber-crime underground, answering questions such as: Who is a real hacker? What life does a hacker lead when not on-line? Is it possible to determine a hacker’s profile on the basis of his behavior or types of intrusion? What is the motive behind phishing, pharming, viruses, and worms? After gaining notoriety for breaking into many high-profile computer systems, the Italian hacker Raoul Chiesa turned to ethical hacking in 1995. Today he uses his skills and abilities to find ways to protect networks and computer systems. Stefania Ducci is a member of the Counter Human Trafficking and Emerging Crimes Unit at the United Nations Interregional Crime and Justice Research Institute (UNICRI). Silvio Ciappi is a criminologist who lectures at the University of Pisa and studies criminal profiling. These three experts with vastly different backgrounds explore the clandestine network of cyber-criminals, providing an unparalleled glimpse into the secret lives of these malevolent individuals.
Simplicity: the sure path to God The saints assure us that simplicity is the virtue most likely to draw us closer to God and make us more like Him. Relying on the words of Jesus and the lives of the saints, Fr. Plus maps out a sure path to the simplicity which Jesus praised, a simplicity that bestows on all of us who seek it: happiness, courage, and inner peace, no matter how complicated our circumstances may be or how crowded our days.
