On 3 November 2007, the Sichuan Transportation Bureau announced that the Sui-Yu Expressway was completed after three years of construction. After completion of the Chongqing section of the road, the 36.64 km (22.77 mi) expressway connected Cheng-Nan Expressway and formed the shortest expressway from Chengdu to Chongqing. The new expressway is 50 km (31 mi) shorter than the pre-existing road between Chengdu and Chongqing; thus journey time between the two cities was reduced by an hour, now taking two and a half hours. The Sui-Yu Expressway is a four lane overpass with a speed limit of 80 km/h (50 mph). The total investment was 1.045 billion yuan.

Wound colonization refers to nonreplicating microorganisms within the wound, while in infected wounds, replicating organisms exist and tissue is injured. All multicellular organisms are colonized to some degree by extrinsic organisms, and the vast majority of these exist in either a mutualistic or commensal relationship with the host. An example of the former is the anaerobic bacteria species, which colonizes the mammalian colon, and an example of the latter is various species of staphylococcus that exist on human skin. Neither of these colonizations are considered infections. The difference between an infection and a colonization is often only a matter of circumstance. Non-pathogenic organisms can become pathogenic given specific conditions, and even the most virulent organism requires certain circumstances to cause a compromising infection. Some colonizing bacteria, such as Corynebacteria sp. and viridans streptococci, prevent the adhesion and colonization of pathogenic bacteria and thus have a symbiotic relationship with the host, preventing infection and speeding wound healing.

Question: What species colonizes the mammalian colon?
Answer: anaerobic bacteria.

Von Neumann's habilitation was completed on December 13, 1927, and he started his lectures as a privatdozent at the University of Berlin in 1928. By the end of 1927, von Neumann had published twelve major papers in mathematics, and by the end of 1929, thirty-two papers, at a rate of nearly one major paper per month. His reputed powers of speedy, massive memorization and recall allowed him to recite volumes of information, and even entire directories, with ease. In 1929, he briefly became a privatdozent at the University of Hamburg, where the prospects of becoming a tenured professor were better, but in October of that year a better offer presented itself when he was invited to Princeton University in Princeton, New Jersey.

As one of the earliest centers of book-printing in Europe (see above: History), Strasbourg for a long time held a large number of incunabula—documents printed before 1500—in her library as one of her most precious heritages. After the total destruction of this institution in 1870, however, a new collection had to be reassembled from scratch. Today, Strasbourg's different public and institutional libraries again display a sizable total number of incunabula, distributed as follows: Bibliothèque nationale et universitaire, ca. 2 098 Médiathèque de la ville et de la communauté urbaine de Strasbourg, 394 Bibliothèque du Grand Séminaire, 238 Médiathèque protestante, 94 and Bibliothèque alsatique du Crédit Mutuel, 5.

In a channel transupport system, several proteins form a contiguous channel traversing the inner and outer membranes of the bacteria. It is a simple system, which consists of only three protein subunits: the ABC protein, membrane fusion protein (MFP), and outer membrane protein (OMP)[specify]. This secretion system transports various molecules, from ions, drugs, to proteins of various sizes (20 - 900 kDa). The molecules secreted vary in size from the small Escherichia coli peptide colicin V, (10 kDa) to the Pseudomonas fluorescens cell adhesion protein LapA of 900 kDa.

Several governments maintain permanent manned research stations on the continent. The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 70 and 350 inhabitants per million square kilometres (180 and 900 per million square miles) at these times. Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment. An Orthodox church—Trinity Church, opened in 2004 at the Russian Bellingshausen Station—is manned year-round by one or two priests, who are similarly rotated every year.

Glaciers pick up rocks and sediment with them as they flow. This causes erosion and the formation of valleys over time. The Inn valley is an example of a valley carved by glaciers during the ice ages with a typical terraced structure caused by erosion. Eroded rocks from the most recent ice age lie at the bottom of the valley while the top of the valley consists of erosion from earlier ice ages. Glacial valleys have characteristically steep walls (reliefs); valleys with lower reliefs and talus slopes are remnants of glacial troughs or previously infilled valleys. Moraines, piles of rock picked up during the movement of the glacier, accumulate at edges, center and the terminus of glaciers.

---

Question: The top of the Inn Valley consists of what?
Answer: erosion from earlier ice ages.

The main mineral resource known on the continent is coal. It was first recorded near the Beardmore Glacier by Frank Wild on the Nimrod Expedition, and now low-grade coal is known across many parts of the Transantarctic Mountains. The Prince Charles Mountains contain significant deposits of iron ore. The most valuable resources of Antarctica lie offshore, namely the oil and natural gas fields found in the Ross Sea in 1973. Exploitation of all mineral resources is banned until 2048 by the Protocol on Environmental Protection to the Antarctic Treaty.

The amount of signal received from a distant transmission source is essentially geometric in nature due to the inverse square law, and this leads to the concept of effective area. This measures the performance of an antenna by comparing the amount of power it generates to the amount of power in the original signal, measured in terms of the signal's power density in Watts per square metre. A half-wave dipole has an effective area of 0.13 2. If more performance is needed, one cannot simply make the antenna larger. Although this would intercept more energy from the signal, due to the considerations above, it would decrease the output significantly due to it moving away from the resonant length. In roles where higher performance is needed, designers often use multiple elements combined together.

Question: What accounts for the geometry involved in the use of an antenna?
Answer: inverse square law.

The shelter of the early people changed dramatically from the paleolithic to the neolithic era. In the paleolithic, people did not normally live in permanent constructions. In the neolithic, mud brick houses started appearing that were coated with plaster. The growth of agriculture made permanent houses possible. Doorways were made on the roof, with ladders positioned both on the inside and outside of the houses. The roof was supported by beams from the inside. The rough ground was covered by platforms, mats, and skins on which residents slept. Stilt-houses settlements were common in the Alpine and Pianura Padana (Terramare) region. Remains have been found at the Ljubljana Marshes in Slovenia and at the Mondsee and Attersee lakes in Upper Austria, for example.

In 1960, Columbia/CBS began negotiations with its main international distributor Philips Records with the goal of CBS starting its own global record company. Philips' acquisition of Mercury Records in the US in 1961 paved the way for this. CBS only had the rights to the Columbia name in North America; therefore the international arm founded in 1961 and launched in 1962 utilized the "CBS Records" name only, with Philips Records distributing the label in Europe. CBS's Mexican record company, Discos Columbia, was renamed Discos CBS by 1963.

Fryderyk's father, Nicolas Chopin, was a Frenchman from Lorraine who had emigrated to Poland in 1787 at the age of sixteen. Nicolas tutored children of the Polish aristocracy, and in 1806 married Justyna Krzyżanowska, a poor relative of the Skarbeks, one of the families for whom he worked. Fryderyk was baptized on Easter Sunday, 23 April 1810, in the same church where his parents had married, in Brochów. His eighteen-year-old godfather, for whom he was named, was Fryderyk Skarbek, a pupil of Nicolas Chopin. Fryderyk was the couple's second child and only son; he had an elder sister, Ludwika (1807–55), and two younger sisters, Izabela (1811–81) and Emilia (1812–27). Nicolas was devoted to his adopted homeland, and insisted on the use of the Polish language in the household.

However, with the Glorious Revolution of 1688 the Church of Scotland was finally unequivocally recognised as a Presbyterian institution by the monarch due to Scottish Presbyterian support for the aforementioned revolution and the Acts of Union 1707 between Scotland and England guaranteed the Church of Scotland's form of government. However, legislation by the United Kingdom parliament allowing patronage led to splits in the Church. In 1733, a group of ministers seceded from the Church of Scotland to form the Associate Presbytery, another group seceded in 1761 to form the Relief Church and the Disruption of 1843 led to the formation of the Free Church of Scotland. Further splits took place, especially over theological issues, but most Presbyterians in Scotland were reunited by 1929 union of the established Church of Scotland and the United Free Church of Scotland.

The synthesis of urea by Friedrich Wöhler opened a new research field, organic chemistry, and by the end of the 19th century, scientists were able to synthesize hundreds of organic compounds. The later part of the 19th century saw the exploitation of the Earth's petrochemicals, after the exhaustion of the oil supply from whaling. By the 20th century, systematic production of refined materials provided a ready supply of products which provided not only energy, but also synthetic materials for clothing, medicine, and everyday disposable resources. Application of the techniques of organic chemistry to living organisms resulted in physiological chemistry, the precursor to biochemistry. The 20th century also saw the integration of physics and chemistry, with chemical properties explained as the result of the electronic structure of the atom. Linus Pauling's book on The Nature of the Chemical Bond used the principles of quantum mechanics to deduce bond angles in ever-more complicated molecules. Pauling's work culminated in the physical modelling of DNA, the secret of life (in the words of Francis Crick, 1953). In the same year, the Miller–Urey experiment demonstrated in a simulation of primordial processes, that basic constituents of proteins, simple amino acids, could themselves be built up from simpler molecules.

Along with the rest of South West England, Somerset has a temperate climate which is generally wetter and milder than the rest of the country. The annual mean temperature is approximately 10 °C (50.0 °F). Seasonal temperature variation is less extreme than most of the United Kingdom because of the adjacent sea temperatures. The summer months of July and August are the warmest with mean daily maxima of approximately 21 °C (69.8 °F). In winter mean minimum temperatures of 1 °C (33.8 °F) or 2 °C (35.6 °F) are common. In the summer the Azores high pressure affects the south-west of England, but convective cloud sometimes forms inland, reducing the number of hours of sunshine. Annual sunshine rates are slightly less than the regional average of 1,600 hours. In December 1998 there were 20 days without sun recorded at Yeovilton. Most the rainfall in the south-west is caused by Atlantic depressions or by convection. Most of the rainfall in autumn and winter is caused by the Atlantic depressions, which is when they are most active. In summer, a large proportion of the rainfall is caused by sun heating the ground leading to convection and to showers and thunderstorms. Average rainfall is around 700 mm (28 in). About 8–15 days of snowfall is typical. November to March have the highest mean wind speeds, and June to August the lightest winds. The predominant wind direction is from the south-west.

The two mature piano sonatas (No. 2, Op. 35, written in 1839 and No. 3, Op. 58, written in 1844) are in four movements. In Op. 35, Chopin was able to combine within a formal large musical structure many elements of his virtuosic piano technique—"a kind of dialogue between the public pianism of the brilliant style and the German sonata principle". The last movement, a brief (75-bar) perpetuum mobile in which the hands play in unmodified octave unison throughout, was found shocking and unmusical by contemporaries, including Schumann. The Op. 58 sonata is closer to the German tradition, including many passages of complex counterpoint, "worthy of Brahms" according to the music historians Kornel Michałowski and Jim Samson.

Although the Spanish Empire had a residual claim on the Marshalls in 1874, when she began asserting her sovereignty over the Carolines, she made no effort to prevent the German Empire from gaining a foothold there. Britain also raised no objection to a German protectorate over the Marshalls in exchange for German recognition of Britain's rights in the Gilbert and Ellice Islands. On October 13, 1885, SMS Nautilus under Captain Rötger brought German emissaries to Jaluit. They signed a treaty with Kabua, whom the Germans had earlier recognized as "King of the Ralik Islands," on October 15.

If access is gained to a car's internal controller area network, it is possible to disable the brakes and turn the steering wheel. Computerized engine timing, cruise control, anti-lock brakes, seat belt tensioners, door locks, airbags and advanced driver assistance systems make these disruptions possible, and self-driving cars go even further. Connected cars may use wifi and bluetooth to communicate with onboard consumer devices, and the cell phone network to contact concierge and emergency assistance services or get navigational or entertainment information; each of these networks is a potential entry point for malware or an attacker. Researchers in 2011 were even able to use a malicious compact disc in a car's stereo system as a successful attack vector, and cars with built-in voice recognition or remote assistance features have onboard microphones which could be used for eavesdropping.
