Le dialogue met, quant à lui, en scène plusieurs protagonistes et fait de l'auditeur le spectateur de leurs aventures. Quel que soit le canevas que vous choisissez, les cinq premières secondes sont déterminantes. Insufflez-y toute la créativité dont vous êtes capable. Autre temps fort, la conclusion du spot. L'auditeur n'en retiendra, au mieux, que les derniers mots. Contrairement à une idée reçue, il n'est pas...

Jupiter (planet) - astronomy.
Beneath the supercritical fluid zone, the pressure reaches 3 million Earth atmospheres. At this depth, the atoms collide so frequently and violently that the hydrogenatoms are ionized—that is, the negatively charged electrons are stripped away from the positively charged protons of the hydrogen nuclei. This ionization results in asea of electrically charged particles that resembles a liquid metal and gives rise to Jupiter’s magnetic field. This liquid metallic hydrogen zone is 30,000 to 40,000 k...

Neptune (planet) - astronomy.
The gaseous atmosphere of Neptune contains hydrogen, helium, and about 3 percent methane. It extends about 5,000 km (about 3,000 mi) above the planet’s ocean.Light reflected from Neptune’s deep atmosphere is blue, because the atmospheric methane absorbs red and orange light but scatters blue light. In 1998 astronomersalso identified molecules of methyl in Neptune’s atmosphere. Methyl molecules each contain one carbon atom and three hydrogen atoms. Methyl molecules are knownas hydrocarbon radical...

Soccer.
Two assistants, known as linesmen or referees’ assistants, aid the referee. Their primary job is to alert the referee when balls go out of the playing area and to assist inmaking offsides calls (see Rules section below). The assistants carry flags, which they wave when the ball leaves the playing area or use to point to the spot where a foul was committed. V EQUIPMENT Soccer is played with a round leather ball. It is between 68 and 71 cm (27 and 28 in) in circumference and weighs between 396...

of the catalyst, including selectivity for the case of more complex catalytic pathways. Figure 2B suggests the local regeneration of deactivated areas as one possible starting point for such a design. In the case of island- forming reactants, for which the reaction oc- curs at the perimeter of these islands (34,35), the generation of additional boundaries should enhance reaction rates. What are good feedback laws for these objectives, and how can they be implemented? Hierarchical con- trol schem...

Ice Hockey.
Each period begins with a face-off at the blue dot at center ice. During the face-off one player from each team lines up at the dot with the stick blade on the ice. After the referee drops the puck, the two players attempt to gain possession of it. Quick hands and strength are essential qualities for players participating in the face-off. Once the puck is dropped, it is in play until an official’s whistle stops it, a goal is scored, or time expires. The team on offense tries to move the puck f...

Computer Memory.
been created, information can be retrieved but not changed. Newer technologies allow ROMs to be semi-permanent—that is, the information can be changed, but ittakes several seconds to make the change. For example, a FLASH memory acts like a ROM because values remain stored in memory, but the values can be changed. C External Memory External memory can generally be classified as either magnetic or optical, or a combination called magneto-optical. A magnetic storage device, such as a computer'shar...

Jaguar (animal) - biology.
scientists have speculated that the jaguar’s robust canine teeth and enormously powerful bite developed specifically to pierce the armor of these reptiles. After killing a large animal, a jaguar will usually drag the carcass into dense cover before beginning to eat. If the kill is made in an open area, jaguars often drag theirprey for considerable distances. On one occasion, a jaguar killed a cow on the edge of a river and swam 790 m (2,600 ft) across the river carrying the cow. Unlike the other...

Bowling.
In each of the first nine frames the bowler rolls one or two balls. If the bowler knocks down all ten pins with the first ball, he or she has rolled a strike, the best roll possible. An X is recorded on the scoresheet or screen, and the bowler receives ten points (the number of pins knocked down) plus a bonus of the number of pins thebowler knocks down in his or her next two bowls. The maximum possible score in a strike frame, therefore, is 30: the strike followed by two more strikes on subseq...

Analyse d'une publicité: Oasis
1. Introduction Les médias ont une place manifeste dans notre société, ils se déclinent sur de multiples supports (presse, radio, télévision, cinéma,…). Ils détiennent le monopole de la communication et ont, par conséquent, une influence considérable sur l’opinion publique. Une partie non négligeable de la population, surtout parmi les plus jeunes, n’est pas consciente du fait qu’un média est un discours, un point de vue, une mise en signes de la réal...

La publicité représente une part croissante de l'activité économique.
les annonceurs furent obligés de recourir à d'autres médias, presse quotidienne, presse périodique, affichage et radios dites « périphériques ». Les filiales des grandes agences américaines dominaient alors la plupart des marchés. Le développement des télévisions privées dans les années quatre-vingt a entraîné un renversement de la situation. D'une pénurie de l'offre d'espaces, on est passé à une surabondance. L'éventail des prix des spots publicitaires s'est considérablement élargi :...

were large, heavy units. After the invention of the transistor in 1948, radios shrank in size to small handheld radio transceivers. Public two-way radios with severalfrequency options are widely available as well. Usually limited in range to a few miles, these units are great aids for such mobile professionals as construction workers,film crews, event planners, and security personnel. Simpler two-way radios, called walkie-talkies, have been popular children’s toys for years. Most walkie-talkiesb...

Water Pollution.
Cryptosporidium in the water supply of Milwaukee, Wisconsin, sickened more than 400,000 people and killed more than 100. H Thermal Pollution Water is often drawn from rivers, lakes, or the ocean for use as a coolant in factories and power plants. The water is usually returned to the source warmer than when itwas taken. Even small temperature changes in a body of water can drive away the fish and other species that were originally present, and attract other species in placeof them. Thermal pol...

Tiger - biology.
have a simple digestive system designed to process meat so that the nutrients can be readily absorbed into the bloodstream. With the exception of white tigers, which have blue eyes, all tigers have yellow eyes. Tigers mainly use vision to find prey. Although tigers see about as well as humansduring the day, their large eye openings gather more light than do human eyes, making tiger night vision far superior to that of humans. In addition, a special structurein the tiger’s eye, called the tapetu...

Asteroid - astronomy.
Asteroids of the S type, related to the stony iron meteorites, make up about 15 percent of the total population of asteroids that can be seen from Earth. Much rarer arethe M-type objects, corresponding in composition to the meteorites known as “irons.” These objects are made up of an iron-nickel alloy and may represent the cores ofbodies that were large enough to differentiate into layers and to melt deep inside. Their rocky outer layers may have been removed by impacts with other asteroids . A...

INTRODUCTION
Quantum Theory, in physics, description of the particles that make up matter and how they interact with each other and with energy.
electron in the same way a particle with momentum would: It bumps the electron and changes the electron’s path. The light is also affected by the collision as though itwere a particle, in that its energy and momentum changes. Momentum is a quantity that can be defined for all particles. For light particles, or photons, momentum depends on the frequency, or color, of the photon, which in turndepends on the photon’s energy. The energy of a photon is equal to a constant number, called Planck’s cons...

Galileo (spacecraft) - astronomy.
Great Red Spot, sustains itself on energy gained from the upper atmosphere, perhaps by absorbing the energy of smaller atmospheric disturbances. In 1999 Galileotook detailed photographs of Io’s volcanic eruptions; scientists hope to use the observations to learn more about similar volcanic activity that occurred on Earth eonsago. Observations taken by Galileo in 2000 lent strength to the theory that Europa may have an ocean of liquid water. The spacecraft’s magnetometer recorded regularchanges i...

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...

Soccer's Big Show Comes to the United States.
There were many doubters, both overseas and within the United States. Some U.S. sportswriters derided the idea of holding the World Cup in the United States asakin to staging the World Series in India—how could there be any local interest? Foreign critics felt that money was the sole reason for FIFA's decision and that thesport was about to be cheapened to make it acceptable to Americans. The rumors flew: FIFA was going to enlarge the goals, it would allow timeouts (unheard of inthe sport) to ac...

Moon - astronomy.
B Volcanic Features Maria, domes, rilles, and a few craters display indisputable characteristics of volcanic origin. Maria are plains of dark-colored rock that cover approximately 40 percent ofthe Moon's visible hemisphere. The maria formed when molten rock erupted onto the surface and solidified between 3.16 billion and 3.96 billion years ago. This rockresembles terrestrial basalt, a volcanic rock type widely distributed on Earth, but the rock that formed the maria has a higher iron content an...

Football.
C Special Teams Each team has players who enter the game during special plays such as kickoffs, field goals, punts, and returns. The kicker kicks off at the beginning of a game or half,and after his team has scored. The kicker also scores points for the offensive team by kicking the ball through the goalpost’s vertical posts, also known as the uprights;these scores are called field goals. When the offensive team must surrender the ball to the opponents, a punter comes in to kick the ball downfi...
