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.
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.
Pocket Book of Hospital Care for Children
The Pocket Book is for use by doctors, nurses and other health workers who are responsible for the care of young children at the first level referral hospitals. This second edition is based on evidence from several WHO updated and published clinical guidelines. It is for use in both inpatient and outpatient care in small hospitals with basic laboratory facilities and essential medicines. In some settings, these guidelines can be used in any facilities where sick children are admitted for inpatient care. The Pocket Book is one of a series of documents and tools that support the Integrated Management of Childhood Illness (IMCI). The guidelines require the hospital to have (1) the capacity to carry out certain essential investigations, such as pulse oximetry, blood glucose, blood smear examinations for malaria parasites, estimation of haemoglobin, packed cell volume and full blood count, blood group and cross-match, and basic microscopy of cerebrospinal fluid and urine; and where possible blood and urine culture, ultrasound and basic x-rays; (2) essential medicines for the care of seriously ill children. Advanced and high care treatment options, such as intensive care or mechanical ventilation, are not described. These guidelines focus on the management of the major causes of childhood mortality in most developing countries, such as newborn problems, pneumonia, diarrhoea, malaria, meningitis, septicaemia, measles and related conditions, severe acute malnutrition and paediatric HIV/AIDS. It also covers some common surgical conditions that can be managed in small hospitals. Details of the evidence on which the Pocket Book is based can be found onWHO website from the published guidelines provided in the bibliography. These guidelines are applicable in most areas of the world and may be adapted to suit country specific circumstances.
Advanced Computer Architecture and Parallel Processing
Computer architecture deals with the physical configuration, logical structure, formats, protocols, and operational sequences for processing data, controlling the configuration, and controlling the operations over a computer. It also encompasses word lengths, instruction codes, and the interrelationships among the main parts of a computer or group of computers. This two-volume set offers a comprehensive coverage of the field of computer organization and architecture.
Stress Appraisal and Coping
The reissue of a classic work, now with a foreword by Daniel Goleman! Here is a monumental work that continues in the tradition pioneered by co-author Richard Lazarus in his classic book Psychological Stress and the Coping Process. Dr. Lazarus and his collaborator, Dr. Susan Folkman, present here a detailed theory of psychological stress, building on the concepts of cognitive appraisal and coping which have become major themes of theory and investigation. As an integrative theoretical analysis, this volume pulls together two decades of research and thought on issues in behavioral medicine, emotion, stress management, treatment, and life span development. A selective review of the most pertinent literature is included in each chapter. The total reference listing for the book extends to 60 pages. This work is necessarily multidisciplinary, reflecting the many dimensions of stress-related problems and their situation within a complex social context. While the emphasis is on psychological aspects of stress, the book is oriented towards professionals in various disciplines, as well as advanced students and educated laypersons. The intended audience ranges from psychiatrists, clinical psychologists, nurses, and social workers to sociologists, anthropologists, medical researchers, and physiologists.
The History of a Crime
On December 1, 1851, Charras shrugged his shoulder and unloaded his pistols. In truth, the belief in the possibility of a coup d'état had become humiliating. The supposition of such illegal violence on the part of M. Louis Bonaparte vanished upon serious consideration. The great question of the day was manifestly the Devincq election; it was clear that the Government was only thinking of that matter. As to a conspiracy against the Republic and against the People, how could any one premeditate such a plot? Where was the man capable of entertaining such a dream? For a tragedy there must be an actor, and here assuredly the actor was wanting. To outrage Right, to suppress the Assembly, to abolish the Constitution, to strangle the Republic, to overthrow the Nation, to sully the Flag, to dishonor the Army, to suborn the Clergy and the Magistracy, to succeed, to triumph, to govern, to administer, to exile, to banish, to transport, to ruin, to assassinate, to reign, with such complicities that the law at last resembles a foul bed of corruption. What! All these enormities were to be committed! And by whom? By a Colossus? No, by a dwarf. People laughed at the notion. They no longer said "What a crime!" but "What a farce!" For after all they reflected; heinous crimes require stature. Certain crimes are too lofty for certain hands. A man who would achieve an 18th Brumaire must have Arcola in his past and Austerlitz in his future. The art of becoming a great scoundrel is not accorded to the first comer. People said to themselves, Who is this son of Hortense? He has Strasbourg behind him instead of Arcola, and Boulogne in place of Austerlitz. He is a Frenchman, born a Dutchman, and naturalized a Swiss; he is a Bonaparte crossed with a Verhuell; he is only celebrated for the ludicrousness of his imperial attitude, and he who would pluck a feather from his eagle would risk finding a goose's quill in his hand. This Bonaparte does not pass currency in the array, he is a counterfeit image less of gold than of lead, and assuredly French soldiers will not give us the change for this false Napoleon in rebellion, in atrocities, in massacres, in outrages, in treason. If he should attempt roguery it would miscarry. Not a regiment would stir. Besides, why should he make such an attempt? Doubtless he has his suspicious side, but why suppose him an absolute villain? Such extreme outrages are beyond him; he is incapable of them physically, why judge him capable of them morally? Has he not pledged honor? Has he not said, "No one in Europe doubts my word?" Let us fear nothing. To this could be answered, Crimes are committed either on a grand or on a mean scale. In the first category there is Caesar; in the second there is Mandrin. Caesar passes the Rubicon, Mandrin bestrides the gutter. But wise men interposed, "Are we not prejudiced by offensive conjectures? This man has been exiled and unfortunate. Exile enlightens, misfortune corrects."
