• LA : Médée de Corneille

  bénéficier de ses qualités, et se prémunir de ses défauts. Dans le cas de Médée, par exemple, le dramaturge Corneille présente au spectateur une femme monstrueuse qui renie son rôle de mère, pour se laisser envahir par la haine qu'elle éprouve en tant que femme trompée. En mettant un tel personnage en scène, l'auteur avertit son public contre toute attitude excessive qui pourrait s'apparenter à celle de Médée. Ici, la femme répudiée par Jason a appris qu'elle allait être condamnée à l'exil, et q...

  FORMULES MOÙCULAIRES Lorsque les atomes sont associés en molécules, il existe plusieurs façons de les représenter. La formule brute d'une molécule en donne les atomes qui la composent avec en indice le nombre de chacun d'entre eux; la formule développée détaille chaque liaison atomique sous la forme d'un trait et chaque atome est représenté ; enfin la formule semi-développée combine les deux et ne met en évidence que les liaisons entre des groupements...

• Rock (mineral).

  pressure mineral assemblage. In a sense, the rock is stuck in a state that is characteristic of its earlier high-temperature and high-pressure environment. Thus,metamorphic rocks carry with them information about the history of temperatures and pressures to which they were subjected. The size, shape, and distribution of mineral grains in a rock are called the texture of the rock. Many metamorphic rocks are named for their main texture. Textures giveimportant clues as to how the rock formed. As t...

• journal - littérature.

  En Europe, un des journaux intimes les plus célèbres est celui de Samuel Pepys (1660-1669), dans lequel l’écrivain non seulement s’observe et se dépeint lui-même avec une lucidité dépourvue de complaisance et de retenue notant ses pensées et ses activités quotidiennes, évoquant son goût pour la musique et le théâtre, son bonheur familial et ses amours passagères, mais aussi décrit les événements dont il est le témoin, en particulier la peste de 1665 et le grand incendie de Londres de 1666, ce qu...

• Le mot "lune" dans l'oeuvre de DESCARTES

  en ses pores, il faut maintenant que je vous parle d'un certain mouvement de toute sa masse, qui est causé par la présence de lalune, comme aussi de quelques particularités qui en dépendent. Pour cet effet, considérez la lune, par exemple vers B , où vous pouvez la supposer comme immobile, à comparaison de lavitesse dont se meut la matière du ciel qui est sous elle ; et considérez que cette matière du ciel ayant moins d'espace entre o et 6 pour y passer, qu'elle n'en aurait entre B et 6 (si la l...

  barbiturates, cocaine, amphetamines, and heroin. When a body is discovered in a lake, stream, river, or ocean and the lungs are found to be filled with water, the medical examiner must determine if the drowningoccurred where the body was found or elsewhere. A standard microscope that can magnify objects to 1500 times their actual size is used to look for the presence orabsence of diatoms, single-celled algae that are found in all natural bodies of water. The absence of diatoms raises the possi...

• Arab Music I INTRODUCTION Umm Kulthum Egyptian singer Umm Kulthum was revered throughout Egypt, North Africa, and the Near East for her powerful voice and improvisational skill.

  The rhythmic structure of Arab music is similarly complex. Rhythmic patterns have up to 48 beats and typically include several downbeats (called dums ) as well as upbeats (called taks) and silences, or rests. To grasp a rhythmic mode, the listener must hear a relatively long pattern. Moreover, the performers do not simply play the pattern; they elaborate upon and ornament it. Often the pattern is recognizable by the arrangement of downbeats. The Rhythm in Arab Music illustration demonstratesa...

• historia teatro

  death, judgement, heaven, and hell - perilously familiar. The cycles stress the goodness and the grace of God, but they also point to his awesome power and the justice of his purposes. They trace the history of the divine will from the fall of Lucifer, through the creation of the world and the fall of Adam, to Christ's acts of redemption. They end with a calculated bang as God's 'for-thoght' is fulfilled in the ending of 'all erthely thyng'. English theatre had its formal beginnings in the L...

• Psychoanalysis.

  A cornerstone of modern psychoanalytic theory and practice is the concept of anxiety, which institutes appropriate mechanisms of defense against certain dangersituations. These danger situations, as described by Freud, are the fear of abandonment by or the loss of the loved one (the object), the risk of losing the object's love,the danger of retaliation and punishment, and, finally, the hazard of reproach by the superego. Thus, symptom formation, character and impulse disorders, andperversions,...

• God. I INTRODUCTION God, the center and focus of religious faith, a holy

  C Islam Islam arose as a powerful reaction against the ancient pagan cults of Arabia, and as a consequence it is the most starkly monotheistic of the three biblically rootedreligions. The name Allah means simply “the God.” He is personal, transcendent, and unique, and Muslims are forbidden to depict him in any creaturely form. The primary creed is that “There is no god but Allah, and Muhammad is the apostle of Allah.” Allah has seven basic attributes: life, knowledge, power, will, hearing, se...

• Sailing.

  the sails sweep across the decks of the vessel from one side to the other, and also because of the danger of breaking spars. In wild jibing, control can be lostmomentarily and, if the seas are high, a small boat can broach —that is, veer on its side with danger of swamping or capsizing. An unintentional jibe in a heavy wind frequently has enough force to break the masts of a vessel. When jibing intentionally, careful sailors always haul in on the boom while turning, so that the boom willtravel...

• Accounting and Bookkeeping.

  The proliferation of mandated notes that accompany financial statements is a particularly visible example. Such notes disclose information that is not already included inthe body of the financial statement. One of the very first notes identifies the accounting methods adopted when acceptable alternative methods also exist, or when theunique nature of the company's business justifies an otherwise unconventional approach. The notes also disclose information about lease commitments, contingent liab...

• Horse Racing.

  interested parties claim the same horse at the same price, lots are drawn to determine the winning offer. Knowledgeable owners and trainers may use claiming races toobtain, at bargain prices, horses whose former owners underestimated the potential of their animals. Two other types of contests are match races and walkovers. A match race pits only two horses, almost always that season’s most successful racers, in a head-to-headduel. A walkover occurs when only one horse has not been scratched (w...

• Horse - biology.

  Horses reach sexual maturity at about one and a half years. The estrous cycle in the mare—a mature female horse—typically lasts 21 days. During the first five days ofthe cycle, the mare is usually receptive to mating. The estrous cycle stops during winter and resumes in the spring, which is the start of the breeding season. Astallion—a mature male horse—approaching a mare in estrus engages in various courtship rituals. These include uttering nickering sounds and sniffing and licking themare’s ge...
