• coeur - Anatomie.

  Le développement de plaques graisseuses est en partie dû à un excès de cholestérol et de graisses animales dans l'alimentation ( voir Nutrition). Un mode de vie sédentaire peut aussi favoriser l'athérosclérose, et l'expérience montre que l'exercice physique peut la prévenir. La morphologie et la personnalité jouent également un rôle : uncaractère perfectionniste ou de battant, par exemple, appelé personnalité de type A, est fréquemment associé à un risque accru de crise cardiaque ( voir Stress...

• Zebra - biology.

  C Life Span Captive zebras have lived into their late 30s. Life expectancy in the wild, where predators abound, is probably not much more than 12 years. IV SOCIAL BEHAVIOR Like horses, zebras have large brains and a wide variety of social behaviors. Although they cannot match the overall intelligence of mammals that hunt, zebras interactwith each other in complex ways. Zebras usually live in groups known as herds, but the social structure of these groups depends on the species. The plains zeb...

• Invertebrate - biology.

  animals with a five-pointed design. They live in the sea and move with the help of tiny fluid-filled feet—another feature found nowhere else in the animal world. Zoologists recognize several different groups of worms. The phylum known as flatworms contains the simplest animals possessing heads. Nerves and sense organs areconcentrated in the head. Most flatworms are paper-thin and live in a variety of wet or damp habitats, including the digestive systems of other animals. Roundwormsrepresent anot...

• Artificial Satellite - astronomy.

  The first stage of a multistage rocket consists of rocket engines that provide a huge amount of force, or thrust. The first stage lifts the entire launch vehicle—with itsload of fuel, the rocket body, and the satellite—off the launch pad and into the first part of the flight. After its engines use all their fuel, the first stage portion of therocket separates from the rest of the launch vehicle and falls to Earth. The second stage then ignites, providing the energy necessary to lift the satellit...

• Buddhism.

  Although never actually denying the existence of the gods, Buddhism denies them any special role. Their lives in heaven are long and pleasurable, but they are in thesame predicament as other creatures, being subject eventually to death and further rebirth in lower states of existence. They are not creators of the universe or incontrol of human destiny, and Buddhism denies the value of prayer and sacrifice to them. Of the possible modes of rebirth, human existence is preferable, because thedeitie...

• Culture.

  form of knowledge, such as scientific discoveries; objects, such as works of art; and traditions, such as the observance of holidays. C1 Ethnocentrism and Cultural Relativism Self-identity usually depends on culture to such a great extent that immersion in a very different culture—with which a person does not share common ways of life orbeliefs—can cause a feeling of confusion and disorientation. Anthropologists refer to this phenomenon as culture shock. In multicultural societies —societies s...

• American Literature: Drama I INTRODUCTION American Literature: Drama, literature intended for performance, written by Americans in the English language.

  American plays, while still a minority, began to appear in the theater repertory in the 19th century. Although American plays were still styled after British models, theirsubject matter came to be based on specifically American incidents or themes. In the United States as in Britain, many plays reflected the influence of romanticism , a European literary and artistic movement. Melodrama, with its outpourings of emotion, was the most prevalent dramatic form in the 19th century. Gothic melodramas...

• Nunavut - Canadian History.

  The Arctic Lands is a complex geological area that is centered on the Arctic Ocean. It includes coastal plains, plateaus, and mountains. Coastal plains and plateaus arefound in the western Northwest Territories section of the Arctic Lands, such as on Victoria Island, which is mostly a large, flat plateau. In striking contrast to theserelatively gentle landscapes, the eastern Nunavut section of the Arctic Lands is dominated by a jagged chain of ice-covered mountains. The mountains on EllesmereIsl...

• Northwest Territories - Geography.

  million years ago by the severe bending (folding) and faulting (breaking) of sedimentary rock that was once part of the Interior Plains. During the Wisconsin Ice Age,alpine glaciers covered the Cordillera, and the movement of the glaciers created razor-sharp peaks and ridges in these mountains. The moving glaciers also createdbroad U-shaped valleys. To the east of the Interior Plains, the ancient rocks of the Canadian Shield are exposed at the Earth’s surface, resulting in a rough, rolling terra...

• Antarctica - Geography.

  The maximum area of sea ice surrounding Antarctica each winter varies from year to year. A marked decline during the 1970s appears to have reversed in more recentdecades, except in the Antarctic Peninsula area. This area has lost almost 40 percent of its sea ice since the start of the 1980s. Sea ice is important to marine life. Krillfeed on algae that live under the sea ice and are released when the ice melts in spring and summer. In turn, many marine animals feed on krill. Emperor penguinsbreed...

• Cancer (medicine).

  unable to repair the DNA damage, p53 instructs the cell to undergo programmed cell death, or apoptosis , putting a stop to runaway cell division before it starts. Programmed cell death is a normal part of cell life and is tightly controlled by many genes, primarily p53. In a cancerous cell, one or more mutations prevent these genes from doing their jobs. When mutated, p53 allows a cell to continue to divide, even with damaged DNA.This can lead to additional mutations in proto-oncogenes or tumor...

• Saudi Arabia - country.

  C Natural Resources Some of the world’s largest oil and natural gas fields lie beneath Saudi Arabia and its offshore waters, representing the country’s most economically important naturalresource. In 2007 Saudi Arabia’s oil reserves were estimated at 264 billion barrels. Before the discovery and exploitation of these reserves in the mid-20th century,Saudi Arabia was one of the poorest countries in the world. Its relatively small population subsisted in a harsh environment with little agricultur...

  PÉRET Benjamin 1899-1959 Poète, né à Rezé, Loire-Atlantique. Un des tout premiers surréalistes; et le plus irréductible parmi les survivants de la «Garde», après la guerre de 39-45. Anarchiste, il s'en fut rejoindre les Brigades internatio­ nales dès les premiers jours de la guerre civile espagnole; et son mau­ vais esprit, comme on dit dans les mess d'officiers, lui valut par contre, au temps de la«drôle de guerre», en 1940, d'être incarcéré pour acti­ vité révolutionnaire. C'est dans la suite...

Les premiers soins sont prodigués sur le terrain : pour traiter les hémorragies, souvent accompagnées d'un état de choc chez les blessés, on utilise notamment des solutés de remplissage (perfusions). L'évacuation des vidimes d'écrasement doit suivre des règles précises. En effet , on rencontre fréquemment le syndrome d'écra­ sement (ou syndrome de Bywaters) , qui résult...

• noblesse.

  Napoléon I er institua une noblesse d'Empire par les décrets de mars 1806, août 1806 et mars 1808. La Restauration, en reconnaissant la validité des titres décernés par l'Empire, encouragea la fusion progressive des élites d'Ancien Régime et de celles qu'avait fait émerger la Révolution. La noblesse libérale, orléaniste et impériale demeura partie intégrante des classes dirigeantes du XIX e siècle grâce à ses alliances matrimoniales, tandis que les anciens aristocrates légitimistes, réfug...

Mais ils comprennent également le tulipier...

• Péguy, Cahiers de la quinzaine (extrait).

  — Plus je vais, répondit gravement le docteur, moins je crois à l’efficacité d’une révolution sociale extraordinaire soudaine, improvisée merveilleuse, avec ou sans fusils et dictature impersonnelle — et plus je crois à l’efficacité d’un travail social modeste, lent, moléculaire, définitif. Mais je ne sais pas pourquoi vous abordez d’aussi grosses questions, que vous avez vous-même réservées, quand je vous demande seulement des renseignements sur les raisons et sur les sentiments que vous avez...

• Rattlesnake - biology.

  Rattlesnakes are declining in number. The greatest threat to their survival is the destruction of their habitats. Snakes also suffer when their habitats are divided intofragments separated by roads, farms, housing developments, and shopping malls, making it harder for them to find mates, food, and breeding sites. In addition, tensof thousands of rattlesnakes are collected and killed each year by hunters who sell their patterned skin so that it can be made into such products as boots, ties, andbe...

• VHH5E11 - Histoire ancienne – Licence Histoire 3e année Devoir

  « Des magistrats ont fait mettre à mort leur propre fils contrairement à toute coutume, à toute loi préférant l'intérêt de la patrie aux liens naturels les plus étroits », cet extrait de l'ouvrage Histoires 1 de Polybe (v. 200 av. J.-C.-v. 118 av. J.-C.) est révélateur de la complexité des relations entretenues entre les pères et les fils dans la société romaine. Organisée autour de la figure paternelle, cette dernière connut de profondes mutations entre l'ép...

• Coral - biology.

  Soft corals lack a distinct skeleton. Although they live in colonies, the individual polyps are fused into a complex body, usually strengthened by small lumps or spikesknown as sclerites, which are made of protein and calcite. Soft corals come in a variety of shapes, including undulating sheets, upright mushroomlike shapes, andbeautiful shapes that form branches. A number of other octocorals have skeletons made from a hard or horny protein, sometimes strengthened with more brittle calcareous dep...

• Blood.

  substances. For example, a person who is blood type A positive will not make antibodies against the A or Rh markers, but will make antibodies against the B marker,which is not on that person’s own red blood cells. If blood containing the B marker (from types B positive, B negative, AB positive, or AB negative) is transfused into thisperson, then the transfused red blood cells will be rapidly destroyed by the patient’s anti-B antibodies. In this case, the transfusion will do the patient no good a...

• Portraiture I INTRODUCTION Portraiture, visual representation of individual people, distinguished by references to the subject's character, social position, wealth, or profession.

  CaracallaCaracalla is a Roman portrait bust in marble of the emperor Marcus Aurelius Antoninus, probably done circa ad 215. Theson of Septimius Severus, Caracalla (as he was known) was a brutal man whose qualities come through in this piece withits dramatic realism. The bust, which is now in the Louvre, Paris, evidently served as the inspiration for Michelangelo’sbust of Brutus more than one thousand years later.Bridgeman Art Library, London/New York The first representations of identifiable ind...

• Frog (animal).

  which means that their body temperature depends on the temperature of the surrounding environment. Few species can tolerate temperatures below 4°C (40°F) orabove 40°C (104°F), and many species can survive only within a narrower range of temperatures. In addition, frogs’ thin, moist skin offers little protection againstwater loss, and when on land the animals must guard against drying out. Many frogs are active at night because temperatures are cooler and humidity is higher thanduring the day. In...

• Fish - biology.

  pectoral fins provide fine movements, add forward thrust, or, together with the pelvic fins, serve as brakes. Typically, fins consist of a thin membrane stretched over afanlike series of thin rods called spines or rays. Most fish breathe underwater with the help of special respiratory organs called gills. Gills are made of a series of thin sheets or filaments through which blood circulates.As water moves into a fish’s mouth and passes over the gills, dissolved oxygen passes across the thin gill...

• Conservation.

  cancers, Hodgkin’s disease and leukemia. Unfortunately, human activities have greatly reduced biodiversity around the world. The 20th century encompasses one of the greatest waves of extinction, orelimination of species, to occur on the planet. The greatest threat to biodiversity is loss of habitat as humans develop land for agriculture, grazing livestock, industry,and habitation. The most drastic damage has occurred in the tropical rain forests, which cover less than seven percent of the Earth’...

• Rain Forest.

  dropped into the heart of the forest by helicopters. Suspended from the crane’s long, movable arm is a large gondola that functions as a mobile treetop laboratory.Moving from tree to tree, forest researchers collect specimens, conduct experiments, and observe life in the canopy frontier. The highest stratum of the rain forest is made up of the emergent trees, those individuals that stick up above the forest canopy. Emergents, which do not form acontinuous layer, are usually the giants of the for...

• Stone Age.

  limestone, quartzite, and indurated shale. Ground stone tools could be made on a wider range of raw material types, including coarser grained rock such as granite. Flaking produces several different types of stone artifacts, which archaeologists look for at prehistoric sites. The parent pieces of rock from which chips have beendetached are called cores, and the chips that have been removed from cores are called flakes. A flake that has had yet smaller flakes removed from one or more edgesin orde...
