  ce symbole sur les tapis persans, dans les jardins moghols, tels que celui du Taj Mahāl, dont la luxuriance, due à la densité des arbres et des fleurs, n'avait rien de commun avec le jardin actuel, dans les jardins turcs, tels que le kiosque de Mourad III, construit dans les jardins de Topkapi à Istanbul, ou dans les jardins mauresques d'Espagne, dont les plus beaux sont ceux de l'Alhambra à Grenade, bien que la végétation ait changé de nos jours.

• L'histoire résulte-t-elle d'un plan caché de la nature ou d'une ruse de la raison ?

  par antagonisme l' insociable sociabilité des hommes, c'est-à-dire le penchant des hommes à entrer en société, qui est pourtant lié à une résistance générale qui menace constamment de rompre cette société. L'homme possède unetendance à s'associer, parce que dans un tel état il se sent plus qu'homme, c'est-à-dire qu'il sent le développementde ses dispositions naturelles. Mais il a aussi un grand penchant à se séparer (s'isoler) parce qu'il trouve en mêmetemps en lui cet attribut qu'est l'insocia...

  evolutiva lógica de los hábitos reproductivos. Mientras que grupos muy diferentes de animales emplean los mismos métodos de fecundación, otros relacionadosestrechamente difieren mucho en ellos.

En esencia, la reproducción sexual en las plantas es similar a la d...

• La connaissance scientifique du vivant exige-t-elle que l'on considère l'organisme comme une machine ?

  De plus le vitalisme affirme que le vivant est animé d'une énergie propre, manifestant une force spécifique qui tend àmaintenir l'organisation. Le vitalisme permet d'éviter le risque de la réduction du vivant à une machine, mais ilsuperpose au déterminisme l'hypothèse d'une force occulte incompréhensible. Il y a donc une finalité interne à toutêtre vivant, car le vivant a quelque chose de rebelle au mécanisme. Le vivant a la spécificité qu'il est irréductible à la simple juxtaposition de...

• Cosmology - astronomy.

  In 1917 American scientist Harlow Shapley measured the distance to several groups of stars known as globular clusters. He measured these distances by using amethod developed in 1912 by American astronomer Henrietta Leavitt. Leavitt’s method relates distance to variations in brightness of Cepheid variables, a class of starsthat vary periodically in brightness. Shapley’s distance measurements showed that the clusters were centered around a point far from the Sun. The arrangement of theclusters was...

  Not all industries require the same degree of automation. Agriculture, sales, and some service industries are difficult to automate. The agriculture industry may becomemore mechanized, especially in the processing and packaging of foods; however, in many service industries such as supermarkets, for example, a checkout countermay be automated and the shelves or supply bins must still be stocked by hand. Similarly, doctors may consult a computer to assist in diagnosis, but they must makethe final...

• 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...

• Poetry I INTRODUCTION Phyllis McGinley American poet and author Phyllis McGinley composed light, witty verse, much of which deals with family life.

  repetition of certain lines and the rhyming of certain lines. The Provençal sestina features a set of six words that end lines (end-words), repeated in a dizzyingly complexpattern. The range of effects created by the poetic line varies tremendously depending on its length, its patterns of repetition, and whether the sentence stops at the end of theline (end-stopped) or carries over the end of the line (enjambed). Many of the earliest examples of Old English poetry feature an accentual line with...

• Sexually Transmitted Infections.

  D Genital Herpes Genital herpes is caused by infection with the herpes simplex virus (HSV). Most cases of genital herpes are due to HSV type 2. Some cases, however, result from genitalinfections with HSV type 1, a common cause of cold sores. Genital herpes causes recurrent outbreaks of painful sores on the genitals, although the disease oftenremains dormant with no symptoms for long periods. In the United States, one in five individuals over the age of 12 is infected with HSV type 2, and the va...

• Natural Satellite - astronomy.

  Titan, Saturn’s largest moon, also has few impact craters. Although icy volcanism from water and ammonia may occur along with some tectonic activity, Titan’s youngsurface is most likely the result of weather processes. Titan’s dense, cold atmosphere precipitates particles of complex organic molecules that accumulate as dunes andmountains. Methane rain erodes the surface and creates lakes at the moon’s poles. Triton’s young surface also may result from processes in its atmosphere, as well aserupt...

Just as each contractor would require a full copy of the blueprint to construct a complete building, each new cell needs a complete copy ofan organism’s genetic information to function properly.

• Air Pollution.

  Several pollutants attack the ozone layer. Chief among them is the class of chemicals known as chlorofluorocarbons (CFCs), formerly used as refrigerants (notably in airconditioners), as agents in several manufacturing processes, and as propellants in spray cans. CFC molecules are virtually indestructible until they reach thestratosphere. Here, intense ultraviolet radiation breaks the CFC molecules apart, releasing the chlorine atoms they contain. These chlorine atoms begin reacting withozone, br...

• 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...

They were, thus, the best economic solution for plantation owners seeking inexpensive labor. The Atlantic slave trade began as a trickle in the 1440s and grew slowly through the 17th century. By 1700, 25,000 slaves, on average, were crossing the Atlantic everyyear. After 1700 the trade grew much more rapidly to a peak in the...
