Cybercrime by Alisdair A. Gillespie - Original PDF
نویسندگان: خلاصه: This is not a usual textbook. It does not purport to be the definitive book on the issue of cybercrime, even if such a thing was possible. Cybercrime, as will be seen, is not easy to define and covers a breadth of subjects. A difficulty with trying to write the ‘definitive’ book on cybercrime is something is bound to be missed out. Trying to cover everything also tends to mean that there is a breadth of cover- age but without depth, partly because publishers (not unreasonably) want books to be of an appropriate (readable!) length. What this book does is to highlight some of the key issues of debate that exist in respect of cybercrime, including what cybercrime is. You will find many of the key areas within this book and perhaps a couple that are not always considered. Each topic follows the same format: the behaviour is discussed critically and an analysis is made of whether the law can solve the behaviour and, if so, how. New to this edition is an examination of the investigation of cybercrime. Chapter 12 considers which agencies investigate cybercrime, and how they are structured in order to do so. Chapter 13 considers the powers of the police and other agencies in the context of investigating cybercrime. The requirement on Internet Service Providers to retain so-called ‘communication data’ (broadly speaking, the who, how and why of communications but not its content) is extremely contro- versial. The increasing use of so-called open source intelligence also proves con- troversial, with the police, and others, looking at what is posted on the internet. These new chapters focus on the key issues of debate and are introduced to allow the other chapters to be put into context.
A Companion to Modern British and Irish Drama, 1880 - 2005 - Original PDF
نویسندگان: خلاصه: This wide-ranging Companion to Modern British and Irish Drama offers challenging analyses of a range of plays in their political contexts. It explores the cultural, social, economic and institutional agendas that readers need to engage with in order to appreciate modern theatre in all its complexity. An authoritative guide to modern British and Irish drama. Engages with theoretical discourses challenging a canon that has privileged London as well as white English males and realism. Topics covered include: national, regional and fringe theatres; post-colonial stages and multiculturalism; feminist and queer theatres; sex and consumerism; technology and globalisation; representations of war, terrorism, and trauma.
Water-Soluble Polymers : Solution Properties and Applications - Original PDF
نویسندگان: خلاصه: This volume contains a series of papers originally presented at the symposium on Water Soluble Polymers: Solution Properties and Applications, sponsored by the Division of Colloids and Surface Chemistry of the American Chemical Society. The symposium took place in Las Vegas City, Nevada on 9 to 11th September, 1997 at the 214th American Chemical Society National Meeting. Recognized experts in their respective fields were invited to speak. There was a strong attendance from academia, government, and industrial research centers. The purpose of the symposium was to present and discuss recent developments in the solution properties of water soluble polymers and their applications in aqueous systems
Laser Application of Polymers - Original PDF
نویسندگان: خلاصه: Abstract Laser ablation of polymers has been studied with designed materials to evaluate the mechanism of ablation and the role of photochemically active groups on the ablation process, and to test possible applications of laser ablation and designed polymers. The incorporation of photochemically active groups lowers the threshold of ablation and allows high-quality structuring without contamination and modification of the remaining surface. The decomposition of the active chromophore takes place during the excitation pulse of the laser and gaseous products are ejected with supersonic velocity. Time-of-flight mass spectrometry reveals that a metastable species is among the products, suggesting that excited electronic states are involved in the ablation process. Experiments with a reference material, i.e., polyimide, for which a photothermal ablation mechanism has been suggested, exhibited pronounced differences. These results strongly suggest that, in case of designed polymers which contain photochemically active groups, a photochemical part in the ablation mechanism cannot be neglected. Various potential applications for laser ablation and the special photopolymers were evaluated and it became clear that the potential of laser ablation and specially designed material is in the field of microstructuring. Laser ablation can be used to fabricate three-dimensional elements, e.g., microoptical elements
Nanocomposites of Polymers and Inorganic Particles - Original PDF
نویسندگان: خلاصه: This chapter deals with composites comprised of polymers and inorganic nanoparticles of rather uniform shape. Such composites are attributed to the class of nanocomposites because of the small size of the embedded particles, while the polymer phase is continuous. The attribution of particles to the class of nanoparticles is somewhat arbitrary; often particles of dimensions up to 50–100 nm are assigned to this notion, and expressions such as nanosized particles, colloids, or, occasionally, ultrafine particles are also used to designate particles as nanoparticles. The small size of the incorporated particles can induce materials properties which differ from those of related composites containing larger particles, for example, as a result of an extremely large interface area, which can readily amount to 107–109 m2 in a cube meter of nanocomposite, or a markedly reduced scattering of visible light. The latter is important if transparent or translucent materials are required for optical applications. This intensity loss of transmitted light by scattering can be estimated with the equation
Microbiology Handbook: Dairy Products - Original PDF
نویسندگان: خلاصه: Milk and dairy products form a central part of the human diet, as they are rich in nutrients. On the other hand, because of their high nutrient value, they favour rapid microbial growth. In some cases, this microbial growth is beneficial, while in others it is undesirable. Dairy products may be contaminated with pathogens or microbial toxins; therefore, the microbiology of these products is of key interest to those in the dairy industry. 'Microbiology Handbook - Dairy Products' provides readers with an easy-to-use reference to microorganisms found in milk and dairy products. The handbook covers: initial microflora; sources of contamination; effects of processing on the survival and growth of microorganisms; spoilage; and hazards identified with the consumption of these products.
