• Julius Caesar I INTRODUCTION Julius Caesar (100-44 BC), Roman general and statesman whose dictatorship was pivotal in Rome's transition from republic to empire.

  V CROSSING THE RUBICON In 52 BC, with Crassus out of the way, Pompey was made sole consul. Combined with his other powers, this gave him a formidable position. Jealous of his younger rival, he determined to break Caesar’s power. To achieve this objective, he first needed to deprive Caesar of the forces he commanded in Gaul. Pompey ordered him toreturn to Rome without his troops. To protect himself, Caesar suggested that he and Pompey both lay down their commands simultaneously, but this propos...

Sie sollteaußerdem Vergleiche zwischen den einzelnen Schulformen (Hauptschule, Realschule, Gymnasium, Gesamtschule) und zwischen den 16 Bundesländern ermöglichen. Eine Rangliste aber lag ausdrücklich nicht in der Absicht der Studie. Da ihre Veröffentlichung in die Phase des Bundestagswahlkampfs fiel, wurden die Ergebnisse zu einembildungspolitischen S...

• Exercise.

  broad, and most studies suggest a positive relationship between physical fitness and mental achievement. The relationship between regular aerobic exercise and cardiovascular health and longevity is well established. Regular exercise leads to a reduction in the risk ofcoronary heart disease, in which fatty deposits (plaque) form in blood vessels supplying the muscular wall of the heart, compromising oxygen delivery to the heartmuscle. In addition, with regular exercise the efficiency of the heart...

• Dogsledding.

  Mushers are caretakers, but also coaches. Top mushers have large kennels, and their preparation for competition begins by buying and breeding race-specific dogs.They train their dogs, decide which to run on certain days, and make adjustments during races by switching and dropping dogs. Serious competitors run their dogsyear-round, using carts and all-terrain vehicles when there is not enough snow on the ground. During races they decide their strategy, choosing when to rest and whento push ahead....

• Photosynthesis - biology.

  P680 in Photosystem II is now electron deficient because it has donated electrons to P700 in Photosystem I. P680 electrons are replenished by the water that has beenabsorbed by the plant roots and transported to the chloroplasts in the leaves. The movement of electrons in Photosystems I and II and the action of an enzyme split thewater into oxygen, hydrogen ions, and electrons. The electrons from water flow to Photosystem II, replacing the electrons lost by P680. Some of the hydrogen ions maybe...

• Aksum.

  doctrine that Christ was both divine and human. The Council of Chalcedon condemned Monophysitism in 451, and since that time the Coptic Church has beenindependent of other Christian churches. After the Council of Chalcedon, priests who continued to teach Monophysitism were persecuted in the eastern Roman Empire, and many migrated to Aksum. The influxof priests, along with the support of the royal family, strengthened missionary efforts in Aksum. Many churches and monasteries were founded after 4...

• Automation.

  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...

  In both Britain and the United States, competition between political parties undermined traditional conceptions of politics rooted in classical and Christian notions ofvirtue and public service. According to this tradition, political leaders should act according to a model of virtue that involved placing the common good above theinterests of a fraction of the society. Leaders acting to benefit only themselves or a narrow portion of the society were considered corrupt. However, party competitionr...

Constitutional courts in some civil-law countries have similar powers. In the United Kingdom no equ...

• Big Bang Theory - astronomy.

  hydrogen atoms. Hydrogen atoms can only absorb and emit specific colors, or wavelengths, of light. The formation of atoms allowed many other wavelengths of light,wavelengths that had been interfering with the free electrons prior to the cooling of the universe, to travel much farther than before. This change set free radiation thatwe can detect today. After billions of years of cooling, this cosmic background radiation is at about 3 K (-270°C/-454°F).The cosmic background radiation was first d...

• X-Ray Astronomy - astronomy.

  Some neutron stars have weaker magnetic fields that allow incoming material to settle onto the entire surface of the neutron star. Eventually, so much material buildsup that the surface layer becomes dense enough to set off a vast thermonuclear explosion, called an outburst. The explosion heats gas to produce X rays. Such aneutron star—called an X-ray burster—can increase its X-ray production by a million times during an outburst. The X-ray glow fades over time, and the binary systementers a lon...

• 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...

• Election.

  majority systems usually reduce the number of competitive political parties—for example, the mostly two-party system in the United States. Proportional representation systems boost participation by increasing the value of a vote to smaller or more marginal portions of a national population. In the UnitedStates, plurality or majority systems have reduced the incentive to vote of citizens who do not identify closely with the Democratic or Republican Party. Disillusionmentwith the major parties and...

• Stroke.

  IV DIAGNOSIS The symptoms typical of a stroke can also be caused by other conditions, including brain tumors, various infections, and overdoses of certain drugs. A patient that hasstrokelike symptoms may undergo a battery of imaging techniques to rule out other medical problems and confirm that a stroke has occurred. The key imagingtechnique used in diagnosing strokes is computed tomography (also known as CT or CAT scanning), which employs X rays to obtain images of the internal structures oft...

• Endocrine System.

  thermostat. When the heat in a house falls, the thermostat responds by switching the furnace on, and when the temperature is too warm, the thermostat switches thefurnace off. Usually, the change that a hormone produces also serves to regulate that hormone's secretion. For example, parathyroid hormone causes the body toincrease the level of calcium in the blood. As calcium levels rise, the secretion of parathyroid hormone then decreases. This feedback mechanism allows for tight controlover hormon...
