In the Age of Reason philosophical tracts and speculations on history and human nature integrated literature with social and political developments. The inevitable reaction was the explosion of Romanticism in the later 18th century which reclaimed the imaginative and fantastical bias of old romances and folk-literature and asserted the primacy of individual experience and emotion. But as the 19th-century went on, European fiction evolved towards realism and naturalism, the meticulous documentation of real life and social trends. Much of the output of naturalism was implicitly polemical, and influenced social and political change, but 20th century fiction and drama moved back towards the subjective, emphasising unconscious motivations and social and environmental pressures on the individual. Writers such as Proust, Eliot, Joyce, Kafka and Pirandello exemplify the trend of documenting internal rather than external realities.

Antigonus II, a student of Zeno of Citium, spent most of his rule defending Macedon against Epirus and cementing Macedonian power in Greece, first against the Athenians in the Chremonidean War, and then against the Achaean League of Aratus of Sicyon. Under the Antigonids, Macedonia was often short on funds, the Pangaeum mines were no longer as productive as under Philip II, the wealth from Alexander's campaigns had been used up and the countryside pillaged by the Gallic invasion. A large number of the Macedonian population had also been resettled abroad by Alexander or had chosen to emigrate to the new eastern Greek cities. Up to two thirds of the population emigrated, and the Macedonian army could only count on a levy of 25,000 men, a significantly smaller force than under Philip II.

Question: Who did Antigonus II defend against?
Answer: Epirus.

On 12 September 1944, King Peter II called on all Yugoslavs to come together under Tito's leadership and stated that those who did not were "traitors", by which time Tito was recognized by all Allied authorities (including the government-in-exile) as the Prime Minister of Yugoslavia, in addition to commander-in-chief of the Yugoslav forces. On 28 September 1944, the Telegraph Agency of the Soviet Union (TASS) reported that Tito signed an agreement with the Soviet Union allowing "temporary entry" of Soviet troops into Yugoslav territory which allowed the Red Army to assist in operations in the northeastern areas of Yugoslavia. With their strategic right flank secured by the Allied advance, the Partisans prepared and executed a massive general offensive which succeeded in breaking through German lines and forcing a retreat beyond Yugoslav borders. After the Partisan victory and the end of hostilities in Europe, all external forces were ordered off Yugoslav territory.

Conversely, DST can adversely affect farmers, parents of young children, and others whose hours are set by the sun and they have traditionally opposed the practice, although some farmers are neutral. One reason why farmers oppose DST is that grain is best harvested after dew evaporates, so when field hands arrive and leave earlier in summer their labor is less valuable. Dairy farmers are another group who complain of the change. Their cows are sensitive to the timing of milking, so delivering milk earlier disrupts their systems. Today some farmers' groups are in favor of DST.

Question: Is it better to harvest grain before or after the morning dew evaporates?
Answer: after.

If a tuberculosis infection does become active, it most commonly involves the lungs (in about 90% of cases). Symptoms may include chest pain and a prolonged cough producing sputum. About 25% of people may not have any symptoms (i.e. they remain "asymptomatic"). Occasionally, people may cough up blood in small amounts, and in very rare cases, the infection may erode into the pulmonary artery or a Rasmussen's aneurysm, resulting in massive bleeding. Tuberculosis may become a chronic illness and cause extensive scarring in the upper lobes of the lungs. The upper lung lobes are more frequently affected by tuberculosis than the lower ones. The reason for this difference is not clear. It may be due either to better air flow, or to poor lymph drainage within the upper lungs.

Question: Approximately what percentage of active TB cases affect the lungs?
Answer: 90%.

The French Marines and naval infantry intended for the invasion of northern Germany were dispatched to reinforce the French Army of Châlons and fell into captivity at Sedan along with Napoleon III. A shortage of officers, following the capture of most of the professional French army at the Siege of Metz and at the Battle of Sedan, led naval officers to be sent from their ships to command hastily assembled reservists of the Garde Mobile. As the autumn storms of the North Sea forced the return of more of the French ships, the blockade of the north German ports diminished and in September 1870 the French navy abandoned the blockade for the winter. The rest of the navy retired to ports along the English Channel and remained in port for the rest of the war.

Some of these estimates also take into account the opportunity cost of investing capital many years before revenues are realized (see Time-value of money). Because of the very long time needed for discovery, development, and approval of pharmaceuticals, these costs can accumulate to nearly half the total expense. A direct consequence within the pharmaceutical industry value chain is that major pharmaceutical multinationals tend to increasingly outsource risks related to fundamental research, which somewhat reshapes the industry ecosystem with biotechnology companies playing an increasingly important role, and overall strategies being redefined accordingly. Some approved drugs, such as those based on re-formulation of an existing active ingredient (also referred to as Line-extensions) are much less expensive to develop.

Question: What happens when companies outsource?
Answer: somewhat reshapes the industry ecosystem with biotechnology companies.

After the Spanish in the 16th century, the first permanent European settlers of North Carolina were English colonists who migrated south from Virginia. The latter had grown rapidly and land was less available. Nathaniel Batts was documented as one of the first of these Virginian migrants. He settled south of the Chowan River and east of the Great Dismal Swamp in 1655. By 1663, this northeastern area of the Province of Carolina, known as the Albemarle Settlements, was undergoing full-scale English settlement. During the same period, the English monarch Charles II gave the province to the Lords Proprietors, a group of noblemen who had helped restore Charles to the throne in 1660. The new province of "Carolina" was named in honor and memory of King Charles I (Latin: Carolus). In 1712, North Carolina became a separate colony. Except for the Earl Granville holdings, it became a royal colony seventeen years later. A large revolt happened in the state in 1711 known as Cary's Rebellion.

The governing bodies in each country operate league systems in a domestic season, normally comprising several divisions, in which the teams gain points throughout the season depending on results. Teams are placed into tables, placing them in order according to points accrued. Most commonly, each team plays every other team in its league at home and away in each season, in a round-robin tournament. At the end of a season, the top team is declared the champion. The top few teams may be promoted to a higher division, and one or more of the teams finishing at the bottom are relegated to a lower division.

The level of Hellenistic achievement in astronomy and engineering is impressively shown by the Antikythera mechanism (150–100 BC). It is a 37-gear mechanical computer which computed the motions of the Sun and Moon, including lunar and solar eclipses predicted on the basis of astronomical periods believed to have been learned from the Babylonians. Devices of this sort are not found again until the 10th century, when a simpler eight-geared luni-solar calculator incorporated into an astrolabe was described by the Persian scholar, Al-Biruni.[not in citation given] Similarly complex devices were also developed by other Muslim engineers and astronomers during the Middle Ages.[not in citation given]

The earliest extant arguments that the world of experience is grounded in the mental derive from India and Greece. The Hindu idealists in India and the Greek Neoplatonists gave panentheistic arguments for an all-pervading consciousness as the ground or true nature of reality. In contrast, the Yogācāra school, which arose within Mahayana Buddhism in India in the 4th century CE, based its "mind-only" idealism to a greater extent on phenomenological analyses of personal experience. This turn toward the subjective anticipated empiricists such as George Berkeley, who revived idealism in 18th-century Europe by employing skeptical arguments against materialism.

Chopin has figured extensively in Polish literature, both in serious critical studies of his life and music and in fictional treatments. The earliest manifestation was probably an 1830 sonnet on Chopin by Leon Ulrich. French writers on Chopin (apart from Sand) have included Marcel Proust and André Gide; and he has also featured in works of Gottfried Benn and Boris Pasternak. There are numerous biographies of Chopin in English (see bibliography for some of these).

It is estimated that in 480 BC, 50 million people lived in the Achaemenid Empire. The empire at its peak ruled over 44% of the world's population, the highest such figure for any empire in history. In Greek history, the Achaemenid Empire is considered as the antagonist of the Greek city states, for the emancipation of slaves including the Jewish exiles in Babylon, building infrastructures such as road and postal systems, and the use of an official language, the Imperial Aramaic, throughout its territories. The empire had a centralized, bureaucratic administration under the emperor, a large professional army, and civil services, inspiring similar developments in later empires. Furthermore, one of the Seven Wonders of the Ancient World, the Mausoleum at Halicarnassus, was built in the empire between 353 and 350 BC.

The period known as the Crusades, a series of religiously motivated military expeditions originally intended to bring the Levant back into Christian rule, began. Several Crusader states were founded in the eastern Mediterranean. These were all short-lived. The Crusaders would have a profound impact on many parts of Europe. Their Sack of Constantinople in 1204 brought an abrupt end to the Byzantine Empire. Though it would later be re-established, it would never recover its former glory. The Crusaders would establish trade routes that would develop into the Silk Road and open the way for the merchant republics of Genoa and Venice to become major economic powers. The Reconquista, a related movement, worked to reconquer Iberia for Christendom.

Larry Christenson, a Lutheran theologian based in San Pedro, California, did much in the 1960s and 1970s to interpret the charismatic movement for Lutherans. A very large annual conference regarding that matter was held in Minneapolis. Charismatic Lutheran congregations in Minnesota became especially large and influential; especially "Hosanna!" in Lakeville, and North Heights in St. Paul. The next generation of Lutheran charismatics cluster around the Alliance of Renewal Churches. There is considerable charismatic activity among young Lutheran leaders in California centered around an annual gathering at Robinwood Church in Huntington Beach. Richard A. Jensen's Touched by the Spirit published in 1974, played a major role of the Lutheran understanding to the charismatic movement.

Prior to 1948, approximately 800,000 Jews were living in lands which now make up the Arab world (excluding Israel). Of these, just under two-thirds lived in the French-controlled Maghreb region, 15–20% in the Kingdom of Iraq, approximately 10% in the Kingdom of Egypt and approximately 7% in the Kingdom of Yemen. A further 200,000 lived in Pahlavi Iran and the Republic of Turkey. Today, around 26,000 Jews live in Arab countries and around 30,000 in Iran and Turkey. A small-scale exodus had begun in many countries in the early decades of the 20th century, although the only substantial aliyah came from Yemen and Syria. The exodus from Arab and Muslim countries took place primarily from 1948. The first large-scale exoduses took place in the late 1940s and early 1950s, primarily in Iraq, Yemen and Libya, with up to 90% of these communities leaving within a few years. The peak of the exodus from Egypt occurred in 1956. The exodus in the Maghreb countries peaked in the 1960s. Lebanon was the only Arab country to see a temporary increase in its Jewish population during this period, due to an influx of refugees from other Arab countries, although by the mid-1970s the Jewish community of Lebanon had also dwindled. In the aftermath of the exodus wave from Arab states, an additional migration of Iranian Jews peaked in the 1980s when around 80% of Iranian Jews left the country.[citation needed]

Matter should not be confused with mass, as the two are not quite the same in modern physics. For example, mass is a conserved quantity, which means that its value is unchanging through time, within closed systems. However, matter is not conserved in such systems, although this is not obvious in ordinary conditions on Earth, where matter is approximately conserved. Still, special relativity shows that matter may disappear by conversion into energy, even inside closed systems, and it can also be created from energy, within such systems. However, because mass (like energy) can neither be created nor destroyed, the quantity of mass and the quantity of energy remain the same during a transformation of matter (which represents a certain amount of energy) into non-material (i.e., non-matter) energy. This is also true in the reverse transformation of energy into matter.

When an electromagnetic wave strikes a plane surface such as the ground, part of the wave is transmitted into the ground and part of it is reflected, according to the Fresnel coefficients. If the ground is a very good conductor then almost all of the wave is reflected (180° out of phase), whereas a ground modeled as a (lossy) dielectric can absorb a large amount of the wave's power. The power remaining in the reflected wave, and the phase shift upon reflection, strongly depend on the wave's angle of incidence and polarization. The dielectric constant and conductivity (or simply the complex dielectric constant) is dependent on the soil type and is a function of frequency.

---

Question: What depends on the polarization and waves angle?
Answer: power remaining.

These reforms were based heavily on French models, as indicated by the adoption of a three-tiered court system. Referred to as Nizamiye, this system was extended to the local magistrate level with the final promulgation of the Mecelle, a civil code that regulated marriage, divorce, alimony, will, and other matters of personal status. In an attempt to clarify the division of judicial competences, an administrative council laid down that religious matters were to be handled by religious courts, and statute matters were to be handled by the Nizamiye courts.
