Vers et virus
Cet ouvrage s'adresse aux informaticiens avec une nouvelle vision du phénomène virus : celle du chasseur et non celle du hacker. Son but n'est pas d'expliquer comment sont conçus les virus, mais comment ils fonctionnent et comment les combattre. L'entrée en matière retrace l'histoire des virus informatiques, histoire fertile en anecdotes et rebondissements. Vient ensuite une déclinaison des différents types de virus avec leurs cibles et leurs attributs. Les virus programmes et les vers sont expliqués très en détail puisque l'auteur présente des visualisations de fichiers en hexadécimal pour faire comprendre aux lecteurs la structure interne des fichiers modernes et la trace qu'y laissent les virus. Viennent ensuite la protection anti-virale dans ses aspects théoriques et méthodologiques, puis les critères de choix d'un bon anti-virus. Cet ouvrage se termine par une analyse de l'évolution de la criminalité informatique et de ses motivations.

Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
Disease Control Priorities in Developing Countries
Based on careful analysis of burden of disease and the costs ofinterventions, this second edition of 'Disease Control Priorities in Developing Countries, 2nd edition' highlights achievable priorities; measures progresstoward providing efficient, equitable care; promotes cost-effectiveinterventions to targeted populations; and encourages integrated effortsto optimize health. Nearly 500 experts - scientists, epidemiologists, health economists,academicians, and public health practitioners - from around the worldcontributed to the data sources and methodologies, and identifiedchallenges and priorities, resulting in this integrated, comprehensivereference volume on the state of health in developing countries.
Plant Virus and Viroid Diseases in the Tropics
Around the globe, besides fungal and bacterial diseases, both virus and viroid diseases have acquired greater importance in the realm of plant pathology and call for effective management measures as they are responsible for heavy yield losses and are a matter of vital importance and concern to farmers, horticulturists, gardeners and foresters. Understanding disease epidemiology is of vital importance for formulating viable disease management practices in a given agro-ecosystem. The development and progress of plant disease epidemics are variable from region to region. Epidemiology is not a static process, but rather a dynamic course that varies with a change in the ecology, host, vector and virus systems.
The Microbial Challenge
Whether we realize it or not, microbes play an ever-present role in our daily lives. Foodborne infections, epidemics, and pandemics are frequently headline news. The Microbial Challenge: Science, Disease, and Public Health, Second Edition, presents a fascinating look at human-microbe interactions and examines the disease producers while discussing how, with knowledge-based preparation, we can live in harmony with microbes. It also discusses the ways in which beneficial microbes are involved in the cycles of nature and in the food industry, and how they are used as research tools. Ideal for undergraduate non-science majors and allied and public health students, this unique text is a hybrid of microbiology and public health and includes material on prions, helminths (worms), biological warfare and terrorism, antibiotic resistance, the global impact of microbial diseases, and immunization. The text helps students better understand the biology of the microbial world and the societal factors that are both the cause and consequences of microbial disease. With up-to-date content, current information on health organizations, including the CDC and WHO, and a new chapter on bacterial genetics, The Microbial Challenge provides a gripping account of the burden of microbial diseases throughout the world.
Children and Young People Living with HIV AIDS
This book focuses on the issues encountered by children and young people who are living with HIV/AIDS. It examines their lived experiences associated with HIV/AIDS, and studies groups of children and youngsters from around the globe. Connecting empirical information with real-life situations, the book brings together results from empirical research that relates to these children and young people. Its chapters can be used as evidence for health care providers to implement socially and culturally appropriate services to assist individuals and groups of children and young people who are living with HIV/AIDS in many societies. Many of these young people are from the most marginalized and vulnerable groups; and many have been orphaned by the death of their HIV-positive parents. Marginalized young people such as refugees, migrants and street children are most at risk due to the use of illicit drugs, their exposure to unprotected sex (in exchange for food, money and protection), and stigma associated with their marginalized lives. The impact that HIV/AIDS has on the opportunities for these young people to be able to lead healthy adult lives is considerable. This book gives a voice to these children and young people and advances our understanding of their lived experiences and needs.
Management of Disease in Wild Mammals
In recent years nobody could have failed to notice the frequent and often sensati- alist media headlines warning of the latest global disease threat to humankind. But behind all the hyperbole lie real challenges related to dealing with the increasing incidence of emerging zoonotic disease events, the majority of which are thought to originate in wildlife (Jones et al. 2008). There are also many important diseases of domestic livestock which also occur in wildlife (e. g. foot and mouth disease and classical swine fever in wild boar, bovine tuberculosis in deer, badgers or possums), some of which can have a devastating impact on the farming industry, the wider rural economy and ultimately the public purse. But we should also not forget that wildlife diseases may have serious implications for the conservation of biodiversity. For some of the rarest, most endangered species (such as the Ethiopian wolf) d- ease may pose the greatest threat to their survival. If we are to avoid or reduce these impacts then we must improve our ability to detect and manage the risks associated with disease in wildlife populations. This is a challenge that will require expertise from many different disciplines: veterinary, ecological, medical, economic, poli- cal and zoological. In such an interdisciplinary field it is difficult to stay up to date with contemporary ideas and with techniques that may be rapidly evolving.
