• routière, sécurité.

  véhicules à moteur, mais des développements prometteurs n'ont pas encore été complètement exploités. 5. 2 Application des règles de la circulation L'application des lois joue un rôle important dans l'amélioration de la sécurité routière. L'action de la police dans ce domaine est plus efficace lorsqu'elle peut s'appuyer sur des moyens technologiques et lorsque les lois sont bien acceptées par la majorité des conducteurs. Les réductions du nombre d'accidents les plus spectaculaires à la suite de...

• changement climatique (faune & Flore).

  Par ailleurs, le réchauffement affecterait de très nombreuses espèces animales comme végétales. On constate d’ores et déjà des modifications de la répartition denombreuses espèces, ainsi qu’un décalage temporel dans les cycles de migration de divers oiseaux. Selon une étude parue dans la revue Nature, le réchauffement du climat pourrait entraîner la disparition de millions d’espèces qui n’auraient pas la possibilité de s’y adapter ou de changer de localisation. Les principales questions sont d...

• obésité - Mécedine.

  un remodelage des habitudes alimentaires et des exercices physiques réguliers, peuvent parfois suffire. Toutes sortes de régimes pour obtenir des pertes de poids rapides font l’objet de publicités dans les magazines. Or, la rapidité de l’amaigrissement n’est pas nécessairementintéressante, ni gage de réussite. Au contraire, les régimes rapides s’avèrent souvent inefficaces à moyen terme. L’une des principales causes d’échecs de la plupart desrégimes est leur aspect contraignant et l’absence de s...

• Pays longtemps féodal, et toujours demeuré indépendant, le Japon ne s'ouvrit au monde qu'avec l'ère Meiji, à partir de 1868.

  mouvements de l'écorce terrestre. Les plaines, qui sont presque toujours périphériques et souvent recouvertes de limons d'origine volcanique, sont rares (moins d'un cinquième de la superficie totale), à l'exception de celles du Kantō (dans laquelle se trouve T ōky ō), de Niigata (sur la mer du Japon), de N ōbi (où se situe Nagoya) ou de Ishikari (plaine de Sapporo). Ces zones basses se raccordent aux hauteurs par des cônes d'alluvion qui constituent des reliefs de collines ou de terrasses. Compl...

• rein (Biologie et Anatomie).

  en une forme active sur les os. Par ailleurs, le rein est l’un des principaux organes producteurs d’érythropoïétine, hormone qui stimule la production des globules rouges parla moelle osseuse. 5 PATHOLOGIES Le rein peut être atteint par des affections de même nature que celles qui touchent les autres organes, par exemple des malformations, des kystes, ou encore des tumeursbénignes ou malignes. En dehors de ces maladies, trois groupes de troubles sont caractéristiques du rein : les néphropathies...

• Flood Control.

  When scientific research into the causes of floods showed that the construction of levees was insufficient as a method of control, the first steps were made to provide forreforestation and soil conservation. The Clarke-McNary Act of 1924, the Mississippi Flood Control Act of 1928, and the McSweeney-McNary Act of 1928 were all directedtoward that end. In 1935 the Soil Conservation Service was established by the Congress of the United States under an act declaring a policy of permanent provision f...

• Checks and Balances.

  no political interest has enough power to prevail over the others. In 1997 and early 1998, for example, the Senate refused to take action on many of President BillClinton’s appointments of new federal court judges. Although the Senate’s power to approve or reject federal court nominees is one of the key checks on presidentialauthority, the dispute between Clinton and the Senate meant that there were not enough federal judges to handle the court’s workload. But the system of checks andbalance was...

• Leaf - biology.

  The mesophyll, sandwiched between the upper and lower epidermis, consists of many thin-walled cells that are usually arranged in two layers. The palisade layer is next to the upper epidermis. It consists of cylindrical cells that are packed closely together. Next to the palisade layer and making up most of the thickness of the leaf bladeis the spongy layer. The spongy layer consists of roundish cells that are packed loosely together and have numerous air spaces between them. In most plants t...

  as well as to the abolition of the House of Lords. He was an active member of the High Court of Justice set up for the king’s trial and boldly signed the king’s deathwarrant. For Cromwell, Charles’s execution was a divine judgment against a tyrant. Following the king’s execution, the Commonwealth of England was formed, ruled bya Council of State that included members of the Rump Parliament.

• Discrimination.

  Throughout United States history many other groups have suffered racial or religious discrimination. Since Europeans first came to America, Native Americans havebeen forcibly deprived of their lands and denied civil rights. Congress enacted the Indian Civil Rights Act in 1968, and the federal courts have entertained a number ofsuits designed to restore to Native American tribes ancestral lands and hunting and fishing rights. Many religious groups, including Roman Catholics, Jews, and others,have...

• Computer Science.

  theoretical research is called algorithmic complexity. Computer scientists in this field seek to develop techniques for determining the inherent efficiency of algorithmswith respect to one another. Another area of theoretical research called computability theory seeks to identify the inherent limits of computation. Software engineers use programming languages to communicate algorithms to a computer. Natural languages such as English are ambiguous—meaning that theirgrammatical structure and vocab...

• Diabetes Mellitus.

  Once diabetes is diagnosed, treatment consists of controlling the amount of glucose in the blood and preventing complications. Depending on the type of diabetes, thiscan be accomplished through regular physical exercise, a carefully controlled diet, and medication. Individuals with Type 1 diabetes must receive insulin, often two to four times a day, to provide the body with the hormone it does not produce. Insulin cannot be takenorally, because it is destroyed in the digestive system. Consequent...

• Panama Canal - Geography.

  The size of ships using the Panama Canal has steadily increased. About 27 percent of the vessels that use the canal are built to the maximum dimensions that can passthrough it (a category called “Panamax”). This has prompted further widening of Gaillard Cut, so that the larger Panamax vessels may transit safely. However, some ofthe world’s commercial and military ships are too large for the canal. Since the 1940s, new U.S. battleships and aircraft carriers have been built exceeding the canal’sdi...

• Military Religious Orders .

  Hospitalers’ charitable functions were playing a secondary role to their military duties. Successes in war defending the Holy Land enriched the order with vast gifts ofproperty in Europe and Palestine. In the 12th century the Hospitalers acquired three impressive fortresses in Palestine at Krak des Chevaliers, Belvoir, and Margat. Atthe height of their power in the 13th century, the Hospitalers regularly supplied 500 knights to defend the Latin Kingdom of Jerusalem against the Empire. The Crusad...

• Abortion.

  Intact dilation and extraction, also referred to as a partial birth abortion, consists of partially removing the fetus from the uterus through the vaginal canal, feet first,and using suction to remove the brain and spinal fluid from the skull. The skull is then collapsed to allow complete removal of the fetus from the uterus. III SOCIAL AND ETHICAL ISSUES Abortion has become one of the most widely debated ethical issues of our time. On one side are pro-choice supporters—individuals who favor a...

• Labor Unions in Canada - Canadian History.

  job. Before collective bargaining begins, workers elect a bargaining committee. The bargaining committee determines the workers’ demands and strategy innegotiations with the employer. Local unions usually are part of national or international unions. These national and international unions employ a staff for organizing workers at the local level, doingresearch, educating union members about labor and political matters, and working with local union leaders. Unions hold regular conventions of dele...

• Skiing.

  Safety is very important to all skiers, and all Alpine resorts have a ski patrol. The ski patrol’s responsibility is to take care of injured skiers, to mark hazardous spots ontrails, to make sure that trails are in good condition before opening them, and, at times, to act as traffic police in congested areas. Skiers are also responsible for takingtheir own safety into consideration, as well as that of others. Anyone who participates in the sport should be aware of the Skier’s Responsibility Code...

  merchants), modernized the rights of neutrals during maritime war, and required blockades to be effective. The Declaration of Paris also initiated the practice of allowingnations other than the original signatories to accede (become a party to) to an agreement. In 1864 a conference convened in Geneva, Switzerland, at the invitation of the Swiss government. The conference approved a convention for the proper treatment ofwounded soldiers on the battlefield and the protection of medical personnel;...

• Tree - biology.

  The major parts of a tree are its roots, trunk, leaves, flowers, and seeds. These components play vital roles in a tree’s growth, development, and reproduction. A Roots Trees are held in place by anchoring organs called roots. In addition to anchoring the tree, roots also absorb water and minerals through tiny structures called roothairs. From the roots the water and mineral nutrients are carried upward through the wood cells to the leaves. Although the internal structure of most kinds of roots...

• Pollution.

  One of the greatest challenges caused by air pollution is global warming, an increase in Earth’s temperature due to the buildup of certain atmospheric gases such ascarbon dioxide. With the heavy use of fossil fuels in the 20th century, atmospheric concentrations of carbon dioxide have risen dramatically. Carbon dioxide and othergases, known as greenhouse gases, reduce the escape of heat from the planet without blocking radiation coming from the Sun. Because of this greenhouse effect,average glob...

• Indian Treaties in Canada - Canadian History.

  Pontiac led an attack on British forts in the Great Lakes area to end British domination and to reinforce Indian autonomy. In response, British king George III issued theRoyal Proclamation of 1763 to try to appease the Indians of the interior. The proclamation set aside land for the Indians west of the Appalachian Mountains anddescribed this land as “lands reserved to [Indians] … as their Hunting Grounds.” The proclamation not only recognized Indian land ownership, but also required thattreaties...

• Nanotechnology.

  ever-finer method of reducing material to the nanoscale size. Instead, nanostructures would be assembled atom by atom and molecule by molecule, from the atomiclevel up, just as occurs in nature. However, assembly at this scale has its own challenges. In school, children learn about some of these challenges when they study the random Brownian motion seen in particles suspended in liquids such as water. Theparticles themselves are not moving. Rather, the water molecules that surround the particles...

• New France - Canadian History.

  the colony now consisted of a governor-general, an intendant , and a Sovereign Council, all located at Québec, with local governors at Trois-Rivières and Montréal, and law courts for all three districts. The senior official was the governor-general, responsible for military matters and for relations with the indigenous nations and theEnglish colonies. The intendant, a noble trained in law, was the official responsible for civil affairs: justice, law enforcement, and the maintenance of the colon...

• Industrial Revolution I INTRODUCTION Industrial Revolution, widespread replacement of manual labor by machines that began in Britain in the 18th century and is still continuing in some parts of the world.

  The most important advance in iron production occurred in 1784 when Englishman Henry Cort invented new techniques for rolling raw iron, a finishing process thatshapes iron into the desired size and form. These advances in metalworking were an important part of industrialization. They enabled iron, which was relativelyinexpensive and abundant, to be used in many new ways, such as building heavy machinery. Iron was well suited for heavy machinery because of its strength anddurability. Because of t...

• Ant - biology.

  The workers of many ant species carry a stinger within the hind end of the gaster. These ants use the stinger to defend against their enemies. In some species, workerants lack a stinger but use the tip of their gaster to squirt or dab poison at other small animals and when fighting battles with other ants, fending off predators, or killinginsects or other animals that they use as food. III PHYSIOLOGY Ants have a rigid, external skeleton called an exoskeleton that gives the soft, inner body its...

• Animal - biology.

  Vertebrates are customarily divided into cold-blooded and warm-blooded animals, but these labels are not very precise. Biologists normally use the terms ectoderm and endoderm to describe temperature regulation more accurately. An ectoderm is an animal whose temperature is dictated by its surroundings, while an endoderm is one that keeps its body at a constant warm temperature by generating internal heat. Reptiles, amphibians, and fish are ectoderms. Although they do not maintain a constant wa...

• South Africa - country.

  The major soil zones are conditioned largely by climatic factors. In the semiarid north and west, soils are alkaline and poorly developed. In the southern part of WesternCape Province, rain falls mostly in the winter months, and soils there form slowly and are generally thin and immature. The moderate temperatures and summer rainfallof the High Veld and eastern coastal areas create conditions for more productive organic decomposition, leading to dark, fertile soils, or chernozems, similar to tho...

  Ce territoire avait cristallisé toutes les préventions accumulées par l'histoire à l'encontre de la France dans le Pacifique. La "solidarité avec le peuple kanak" toutefois s'est estompée devant la nécessité de remettre de l'ordre dans les affaires intérieures de la totalité des pays mélanésiens ; mais ceux-ci avaient constitué un groupe dit du "Fer de lance" pour faire pression sur la France. Sur le terrain même, la période de cohabitation politique (1986-1988) au sein du pouvoir central, à Par...

• Que pensez-vous de ce propos d'un philosophe contemporain : « Le vrai nom de l'attention n'est pas anticipation mais étonnement, elle est le contraire de la précipitation et de la prévention »?

  qui se présente, les fonctions perceptives tâtonnent en quelque sorte et ne parviennent pas à se fixer, en sorte qu'il n'y a pas d'attention véritable : la préperception trouble la perception. C'est que l'anticipation est alors facteur de prévention et de précipitation: prévenu, l'esprit se porte à côté de ce qui se présente; dans sa hâte de retrouver le connu, il manque ce qu'il y a à connaître. Synthèse. - La réponse à faire à la...

Le cas le plus fréquent est la prévention du tétanos par des gammaglobulines spécifiques de cette infection, quand un blessé a une plaie souillée. Les gammaglobulines injectées agissent par elles-mêmes, sans qu’intervienne le système immunitaire du sujet. C’est pourquoi cette méthode est dite passive, par opposition à la vaccination, dans la...
