  plateau central, élément du socle primaire, où les oueds s'enfoncent profondément jusqu'à l'Océan, isolant une région aux portes mêmes de la capitale ; puis le Dir (le « poitrail »), piémont aux terres riches en eau s'étendant de Beni-Mellal jusqu'au sud de Marrakech ; enfin, la plaine triangulaire du Sous débouchant sur l'Atlantique à Agadir. Mais l'originalité du Maroc tient surtout à la grande étendue des plaines atlantiques (Chaouïa, Doukkala, Abda), qui s'intercalent entre...

  2.1. 3 Allumage Un moteur à explosion à essence est aussi appelé moteur à allumage commandé, car il nécessite la présence d'une étincelle électrique pour enflammer le mélange d'air et de carburant. Cette étincelle est délivrée par une bougie, qu'alimente un courant électrique de haute tension, fourni en général par une batterie et une bobine. En revanche, un moteur Diesel n'a pas besoin de système d'allumage, car l'inflammation du carburant se fait spontanément lors de l'injection du gazole dan...

• science - Biologiste / Naturaliste.

  Les méthodes et résultats scientifiques modernes apparaissent au XVII e siècle grâce à la combinaison des capacités de théoricien et d'artisan de Galilée. Aux anciennes méthodes fondées sur l'induction et la déduction, Galilée ajoute la vérification systématique par l'expérience, en utilisant les outils scientifiques nouvellement inventés telsque le télescope, le microscope et le thermomètre. Vers la fin du XVII e siècle, l'expérimentation est élargie par l'utilisation du baromètre découvert p...

• droit constitutionnel

  B/ L’objet du droit constitutionnel ou l’encadrement du jeu politique Le droit constitutionnel a pour objet l’encadrement juridique des phénomènes politiques. La formule de G. Vedel souligne que le droit constitutionnel détermine les conditions dans lesquelles le pouvoir s’exerce, et pose les règles du jeu politique : Les acteurs politiques vont-ils se soumettre à cette règle du jeu ? La règle du pouvoir est une histoire de la violence, car la conquête et l’exercice du pouvoir sont...

• barrage.

  Les tunnels ainsi formés sont souvent transformés et réutilisés après l’achèvement de l’ouvrage. Si les conditions topographiques empêchent la réalisation de canaux de dérivation, un barrage peut être construit en deux étapes. On établit alors un batardeau sur la moitié de la largeur de la rivière, pendant la construction de la partie basse du barrage. Ce batardeau est ensuite enlevé et un second est établi autour de la partie opposée du site. L’élaboration de grands barrages peut s’étendre sur...

  Des pouvoirs de résolution encore plus élevés peuvent être atteints en espaçant les antennes sur des milliers de kilomètres. Mais il devient alors plus difficile de transmettredirectement les signaux de chaque antenne en un lieu de traitement commun : les signaux captés par chaque antenne sont donc enregistrés, puis expédiés vers un centrede traitement informatique. Cette technique d'interférométrie à très large base (VLBI, pour Very Long Baseline Interferometry) requiert l'utilisation d'horloge...

  were usually natural caves. Eventually people learned to dip branches in pitch to form torches. They created crude lamps by filling a hollowed out piece of stone withmoss soaked in oil or tallow (a substance derived from animal fat). By cooking with fire, prehistoric people made the meat of the animals they killed more palatable and digestible. They learned to preserve meat by smoking it over a fire,vastly decreasing the danger of periodic starvation. Cooking also enabled them to add some for...

  Even one of Chiang's allied commanders, Zhang Xueliang, who had been expelled from Manchuria after the Mukden Incident, came to doubt the wisdom of Chiang'sapproach. In 1936 Zhang held Chiang prisoner in Xi'an until Chiang agreed to join the Communists in an allied front against Japan. Chiang later denied making anyagreement.

• Stem Cell.

  The medical profession used adult stem cells to treat diseases long before anyone isolated one. In 1968 scientists performed the first successful bone marrowtransplant, a procedure in which a patient receives an infusion of healthy bone marrow cells. The purpose of such transplants is to restore the blood-making capabilitiesof the patient’s diseased bone marrow after extremely strong chemotherapy has destroyed that bone marrow. From the beginning investigators suspected that stemcells in the inf...

Le premier janvier de la même année, l’écrivain Louis Boisrond-Tonnerre (1776-1806) rédige la proclamation d’indépendance qui ouvre le champ à une littérature nationaliste.

• Aging - biology.

  Different theories have been proposed to explain how SF works. One theory is based on the assumption that aging, and diseases that occur more frequently withadvancing age, are caused by structural damage to cells. This damage accumulates in tiny amounts each time the cell divides, eventually preventing the cell fromcarrying out normal functions. One cause of this damage may be free radicals, which are chemical compounds found in the environment and also generated by normal chemical reactions in...

  frequency, column (d), is the ratio of the frequency of an interval to the total count; the relative frequency is multiplied by 100 to obtain the percent relative frequency.The cumulative frequency, column (e), represents the number of students receiving grades equal to or less than the range in each succeeding interval; thus, thenumber of students with grades of 30 or less is obtained by adding the frequencies in column (c) for the first three intervals, which total 53. The cumulative relativef...

• Suicide.

  C Sociological Theories Most social scientists believe that a society’s structure and values can influence suicide rates. French sociologist Émile Durkheim argued that suicide rates are related tosocial integration —that is, the degree to which an individual feels part of a larger group.

As one example of the significance of social bond...

In 1984, the U.S. government appropriated funds for the construction of aninstallation called the very long baseline array (VLBA), a network of 10 radio antennas spread from the U.S.-Canadian border to Puerto Rico and from Hawaii to the U.S.Atlantic coast. The VLBA is expected to provide angular resolutions in the range of 200-millionths of an arc second. Canada and Australia are both planning similarprogr...

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...

  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...
