Firestone Tire and Rubber Company is an American tire company founded by Harvey S. Firestone (1868–1938) in 1900 initially to supply solid rubber side-wire tires for fire apparatus , and later, pneumatic tires for wagons, buggies , and other forms of wheeled transportation common in the era. Firestone soon saw the huge potential for marketing tires for automobiles , and the company was a pioneer in the mass production of tires. Harvey S. Firestone had a friendship with Henry Ford , and used this to become the original equipment supplier of Ford Motor Company automobiles, and was also active in the replacement market.
184-551: In 1988, the company was sold to the Japanese Bridgestone Corporation. Firestone was originally based in Akron, Ohio , also the hometown of its archrival, Goodyear Tire and Rubber Company , and two other midsized competitors, General Tire and Rubber Company and B.F. Goodrich Company . Founded on August 3, 1900, the company initiated operations with 12 employees. Together, Firestone and Goodyear were
368-500: A low unemployment rate of around 2.6%. Its poverty rate is the second highest among the G7 countries, and exceeds 15.7% of the population. Japan has the highest ratio of public debt to GDP among advanced economies, with a national debt estimated at 248% relative to GDP as of 2022 . The Japanese yen is the world's third-largest reserve currency after the US dollar and the euro. Japan
552-491: A precipitate of aluminium hydroxide , Al(OH) 3 , forms. This is useful for clarification of water, as the precipitate nucleates on suspended particles in the water, hence removing them. Increasing the pH even further leads to the hydroxide dissolving again as aluminate , [Al(H 2 O) 2 (OH) 4 ] , is formed. Aluminium hydroxide forms both salts and aluminates and dissolves in acid and alkali, as well as on fusion with acidic and basic oxides. This behavior of Al(OH) 3
736-701: A security alliance . The United States is a major market for Japanese exports and a major source of Japanese imports, and is committed to defending the country, with military bases in Japan. In 2016, Japan announced the Free and Open Indo-Pacific vision, which frames its regional policies. Japan is also a member of the Quadrilateral Security Dialogue ("the Quad"), a multilateral security dialogue reformed in 2017 aiming to limit Chinese influence in
920-525: A "less classical sound". This name persisted: although the -um spelling was occasionally used in Britain, the American scientific language used -ium from the start. Most scientists throughout the world used -ium in the 19th century; and it was entrenched in several other European languages, such as French , German , and Dutch . In 1828, an American lexicographer, Noah Webster , entered only
1104-499: A Swedish chemist, Jöns Jacob Berzelius , in which the name aluminium is given to the element that would be synthesized from alum. (Another article in the same journal issue also refers to the metal whose oxide is the basis of sapphire , i.e. the same metal, as to aluminium .) A January 1811 summary of one of Davy's lectures at the Royal Society mentioned the name aluminium as a possibility. The next year, Davy published
1288-561: A chemistry textbook in which he used the spelling aluminum . Both spellings have coexisted since. Their usage is currently regional: aluminum dominates in the United States and Canada; aluminium is prevalent in the rest of the English-speaking world. In 1812, British scientist Thomas Young wrote an anonymous review of Davy's book, in which he proposed the name aluminium instead of aluminum , which he thought had
1472-652: A country's commitment to environmental sustainability. Japan is the world's fifth-largest emitter of carbon dioxide . As the host and signatory of the 1997 Kyoto Protocol , Japan is under treaty obligation to reduce its carbon dioxide emissions and to take other steps to curb climate change. In 2020, the government of Japan announced a target of carbon-neutrality by 2050. Environmental issues include urban air pollution ( NOx , suspended particulate matter , and toxics ), waste management , water eutrophication , nature conservation , climate change , chemical management and international co-operation for conservation. Japan
1656-786: A domestic tire plant, which gave it a virtual monopoly. This included both general price and foreign exchange controls . When the ten-year period came to an end in 1979, Firestone retaliated by increasing production, making entry less attractive. Headquarters eventually canceled expansion and failed negotiations led to no further investments. Bridgestone Americas, which has served as the American branch of Japan-based Bridgestone since 1992, moved their corporate office to downtown Nashville in October 2017. In April 2012, Bridgestone Americas opened up its new Bridgestone Americas Technical Center in Akron, Ohio. The $ 100 million facility, located near
1840-545: A kingdom in central Japan in 660 BC, beginning a continuous imperial line . Japan first appears in written history in the Chinese Book of Han , completed in 111 AD. Buddhism was introduced to Japan from Baekje (a Korean kingdom) in 552, but the development of Japanese Buddhism was primarily influenced by China. Despite early resistance, Buddhism was promoted by the ruling class, including figures like Prince Shōtoku , and gained widespread acceptance beginning in
2024-491: A large cooperative sector, with three of the world's ten largest cooperatives, including the largest consumer cooperative and the largest agricultural cooperative as of 2018 . It ranks highly for competitiveness and economic freedom . Japan ranked sixth in the Global Competitiveness Report in 2019. It attracted 31.9 million international tourists in 2019, and was ranked eleventh in

#17327832557652208-479: A major catalyst for further administrative reforms. These reforms culminated with the promulgation of the Taihō Code , which consolidated existing statutes and established the structure of the central and subordinate local governments. These legal reforms created the ritsuryō state, a system of Chinese-style centralized government that remained in place for half a millennium. The Nara period (710–784) marked
2392-916: A month of waiting, the delegation was brought to meet Taylor, and after a further six months of negotiations the company signed a Memorandum of Understanding (MOU) with the National Patriotic Reconstruction Assembly Government's Ministry of Finance in January 1992. This MOU provided for taxes to be paid by Firestone to the Taylor government, and for the Taylor government to provide protection to Firestone's employees and assets in Liberia. Firestone resumed operations in March 1992, but once again had to halt in October that same year as hostilities escalated. Over this period,
2576-554: A new constitution emphasizing liberal democratic practices. The Allied occupation ended with the Treaty of San Francisco in 1952, and Japan was granted membership in the United Nations in 1956. A period of record growth propelled Japan to become the second-largest economy in the world; this ended in the mid-1990s after the popping of an asset price bubble , beginning the " Lost Decade ". In 2011, Japan suffered one of
2760-465: A new system of taxation. The true aim of the reforms was to bring about greater centralization and to enhance the power of the imperial court, which was also based on the governmental structure of China. Envoys and students were dispatched to China to learn about Chinese writing, politics, art, and religion. The Jinshin War of 672, a bloody conflict between Prince Ōama and his nephew Prince Ōtomo , became
2944-441: A probable cause for it being soft with a low melting point and low electrical resistivity . Aluminium metal has an appearance ranging from silvery white to dull gray depending on its surface roughness . Aluminium mirrors are the most reflective of all metal mirrors for near ultraviolet and far infrared light. It is also one of the most reflective for light in the visible spectrum, nearly on par with silver in this respect, and
3128-683: A process termed passivation . Because of its general resistance to corrosion, aluminium is one of the few metals that retains silvery reflectance in finely powdered form, making it an important component of silver-colored paints. Aluminium is not attacked by oxidizing acids because of its passivation. This allows aluminium to be used to store reagents such as nitric acid , concentrated sulfuric acid , and some organic acids. In hot concentrated hydrochloric acid , aluminium reacts with water with evolution of hydrogen, and in aqueous sodium hydroxide or potassium hydroxide at room temperature to form aluminates —protective passivation under these conditions
3312-654: A reduction from $ 28.8 million–$ 38.5 million to $ 2.4 million.) Shortly afterward, Firestone extended this to a complete withdrawal by the end of the 1974 season. The manufacturer returned in 1995 to the CART Series with technical assistance from Bridgestone. Firestone has been the sole supplier of tires for the IndyCar Series since 2000 and will run until the 2030 season. In 1950, Firestone along with General Motors and Standard Oil , were charged and convicted of criminal conspiracy for their part in
3496-525: A refractory material, and in ceramics , as well as being the starting material for the electrolytic production of aluminium. Sapphire and ruby are impure corundum contaminated with trace amounts of other metals. The two main oxide-hydroxides, AlO(OH), are boehmite and diaspore . There are three main trihydroxides: bayerite , gibbsite , and nordstrandite , which differ in their crystalline structure ( polymorphs ). Many other intermediate and related structures are also known. Most are produced from ores by
3680-465: A significant shift to urbanization. The early 20th century saw a period of Taishō democracy (1912–1926) overshadowed by increasing expansionism and militarization . World War I allowed Japan, which joined the side of the victorious Allies , to capture German possessions in the Pacific and China in 1920 . The 1920s saw a political shift towards statism , a period of lawlessness following
3864-474: A stable noble gas configuration. Accordingly, the combined first three ionization energies of aluminium are far lower than the fourth ionization energy alone. Such an electron configuration is shared with the other well-characterized members of its group, boron , gallium , indium , and thallium ; it is also expected for nihonium . Aluminium can surrender its three outermost electrons in many chemical reactions (see below ). The electronegativity of aluminium

This results in one of the world's highest levels of crop yields per unit area, with an agricultural self-sufficiency rate of about 50% as of 2018 . Japan's small agricultural sector is highly subsidized and protected . There has been a growing concern about farming as farmers are aging with a difficult time finding successors. Aluminum Aluminium (or aluminum in North American English )
4232-459: A tread separation than any other SUV. Labour economists Alan Krueger and Alexandre Mas concluded that one of the main reasons for the high defect rate of Firestone tires was linked to a dispute between the unions and Firestone at the Decatur plant 1994–1996. They find that the tires manufactured at the plant in question around this time featured substantially increased defect rates, rising with
4416-820: A variety of wet processes using acid and base. Heating the hydroxides leads to formation of corundum. These materials are of central importance to the production of aluminium and are themselves extremely useful. Some mixed oxide phases are also very useful, such as spinel (MgAl 2 O 4 ), Na-β-alumina (NaAl 11 O 17 ), and tricalcium aluminate (Ca 3 Al 2 O 6 , an important mineral phase in Portland cement ). The only stable chalcogenides under normal conditions are aluminium sulfide (Al 2 S 3 ), selenide (Al 2 Se 3 ), and telluride (Al 2 Te 3 ). All three are prepared by direct reaction of their elements at about 1,000 °C (1,800 °F) and quickly hydrolyze completely in water to yield aluminium hydroxide and
4600-575: A way of purifying bauxite to yield alumina, now known as the Bayer process , in 1889. Modern production of aluminium is based on the Bayer and Hall–Héroult processes. As large-scale production caused aluminium prices to drop, the metal became widely used in jewelry, eyeglass frames, optical instruments, tableware, and foil , and other everyday items in the 1890s and early 20th century. Aluminium's ability to form hard yet light alloys with other metals provided
4784-434: Is Al. Al was present in the early Solar System with abundance of 0.005% relative to Al but its half-life of 728,000 years is too short for any original nuclei to survive; Al is therefore extinct . Unlike for Al, hydrogen burning is the primary source of Al, with the nuclide emerging after a nucleus of Mg catches a free proton. However, the trace quantities of Al that do exist are the most common gamma ray emitter in
4968-497: Is Tokyo ; the Greater Tokyo Area is the largest metropolitan area in the world, with more than 38 million inhabitants as of 2016. Japan is divided into 47 administrative prefectures and eight traditional regions . About three-quarters of the country's terrain is mountainous and heavily forested, concentrating its agriculture and highly urbanized population along its eastern coastal plains . The country sits on
5152-407: Is paramagnetic and thus essentially unaffected by static magnetic fields. The high electrical conductivity, however, means that it is strongly affected by alternating magnetic fields through the induction of eddy currents . Aluminium combines characteristics of pre- and post-transition metals. Since it has few available electrons for metallic bonding, like its heavier group 13 congeners, it has
5336-529: Is reclaimed land ( umetatechi ). Lake Biwa is an ancient lake and the country's largest freshwater lake. Japan is substantially prone to earthquakes , tsunami and volcanic eruptions because of its location along the Pacific Ring of Fire. It has the 17th highest natural disaster risk as measured in the 2016 World Risk Index. Japan has 111 active volcanoes. Destructive earthquakes, often resulting in tsunami, occur several times each century;
5520-429: Is small and highly charged ; as such, it has more polarizing power , and bonds formed by aluminium have a more covalent character. The strong affinity of aluminium for oxygen leads to the common occurrence of its oxides in nature. Aluminium is found on Earth primarily in rocks in the crust , where it is the third-most abundant element , after oxygen and silicon , rather than in the mantle , and virtually never as
5704-483: Is 1.61 (Pauling scale). A free aluminium atom has a radius of 143 pm . With the three outermost electrons removed, the radius shrinks to 39 pm for a 4-coordinated atom or 53.5 pm for a 6-coordinated atom. At standard temperature and pressure , aluminium atoms (when not affected by atoms of other elements) form a face-centered cubic crystal system bound by metallic bonding provided by atoms' outermost electrons; hence aluminium (at these conditions)

The system, however, is not shared by the other members of its group: boron has ionization energies too high to allow metallization, thallium has a hexagonal close-packed structure, and gallium and indium have unusual structures that are not close-packed like those of aluminium and thallium. The few electrons that are available for metallic bonding in aluminium are
6624-522: Is almost never found in the elemental state; instead it is found in oxides or silicates. Feldspars , the most common group of minerals in the Earth's crust, are aluminosilicates. Aluminium also occurs in the minerals beryl , cryolite , garnet , spinel , and turquoise . Impurities in Al 2 O 3 , such as chromium and iron , yield the gemstones ruby and sapphire , respectively. Native aluminium metal

Native aluminium has been reported in cold seeps in the northeastern continental slope of the South China Sea . It is possible that these deposits resulted from bacterial reduction of tetrahydroxoaluminate Al(OH) 4 . Although aluminium is a common and widespread element, not all aluminium minerals are economically viable sources of

Aluminium also bears minor similarities to the metalloid boron in the same group: AlX 3 compounds are valence isoelectronic to BX 3 compounds (they have the same valence electronic structure), and both behave as Lewis acids and readily form adducts . Additionally, one of the main motifs of boron chemistry is regular icosahedral structures, and aluminium forms an important part of many icosahedral quasicrystal alloys, including
8096-476: Is low in comparison with many other metals. All other isotopes of aluminium are radioactive . The most stable of these is Al : while it was present along with stable Al in the interstellar medium from which the Solar System formed, having been produced by stellar nucleosynthesis as well, its half-life is only 717,000 years and therefore a detectable amount has not survived since the formation of
8280-500: Is negligible. Aqua regia also dissolves aluminium. Aluminium is corroded by dissolved chlorides , such as common sodium chloride , which is why household plumbing is never made from aluminium. The oxide layer on aluminium is also destroyed by contact with mercury due to amalgamation or with salts of some electropositive metals. As such, the strongest aluminium alloys are less corrosion-resistant due to galvanic reactions with alloyed copper , and aluminium's corrosion resistance
8464-521: Is not as important. It is a polymer with the formula (AlH 3 ) n , in contrast to the corresponding boron hydride that is a dimer with the formula (BH 3 ) 2 . Aluminium's per-particle abundance in the Solar System is 3.15 ppm (parts per million). It is the twelfth most abundant of all elements and third most abundant among the elements that have odd atomic numbers, after hydrogen and nitrogen. The only stable isotope of aluminium, Al,

In the summer, the region sometimes experiences extremely hot temperatures because of the Foehn . The Central Highland has a typical inland humid continental climate, with large temperature differences between summer and winter. The mountains of
8832-416: Is quite soft and lacking in strength. In most applications various aluminium alloys are used instead because of their higher strength and hardness. The yield strength of pure aluminium is 7–11 MPa , while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium is ductile , with a percent elongation of 50-70%, and malleable allowing it to be easily drawn and extruded . It
9016-439: Is restricted for habitation. Thus the habitable zones, mainly in the coastal areas, have very high population densities: Japan is the 40th most densely populated country even without considering that local concentration. Honshu has the highest population density at 450 persons/km (1200/sq mi) as of 2010 , while Hokkaido has the lowest density of 64.5 persons/km as of 2016 . As of 2014 , approximately 0.5% of Japan's total area
9200-435: Is soft, nonmagnetic , and ductile . It has one stable isotope, Al, which is highly abundant, making aluminium the twelfth-most common element in the universe. The radioactivity of Al leads to it being used in radiometric dating . Chemically, aluminium is a post-transition metal in the boron group ; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state . The aluminium cation Al

#17327832557659568-547: Is termed amphoterism and is characteristic of weakly basic cations that form insoluble hydroxides and whose hydrated species can also donate their protons. One effect of this is that aluminium salts with weak acids are hydrolyzed in water to the aquated hydroxide and the corresponding nonmetal hydride: for example, aluminium sulfide yields hydrogen sulfide . However, some salts like aluminium carbonate exist in aqueous solution but are unstable as such; and only incomplete hydrolysis takes place for salts with strong acids, such as

The military
14352-607: The University of Pennsylvania taught classes and wrote papers on the issues of misjudgments and poor decision-making by the management of Firestone. After years of bad publicity and millions paid out in compensation to victims, Firestone was losing vast amounts of money, and its name was severely damaged. Firestone established the Firestone Natural Rubber plantation in Harbel, Liberia in 1926. From 1926 until
14536-475: The aluminum spelling in his American Dictionary of the English Language . In the 1830s, the -um spelling gained usage in the United States; by the 1860s, it had become the more common spelling there outside science. In 1892, Hall used the -um spelling in his advertising handbill for his new electrolytic method of producing the metal, despite his constant use of the -ium spelling in all
14720-423: The chemical formula Al 2 O 3 , commonly called alumina . It can be found in nature in the mineral corundum , α-alumina; there is also a γ-alumina phase. Its crystalline form, corundum, is very hard ( Mohs hardness 9), has a high melting point of 2,045 °C (3,713 °F), has very low volatility, is chemically inert, and a good electrical insulator, it is often used in abrasives (such as toothpaste), as
14904-401: The end of the shogunate and the restoration of imperial power in 1868. In the Meiji period , the Empire of Japan pursued rapid industrialization and modernization , as well as militarism and overseas colonization . In 1937, Japan invaded China , and in 1941 attacked the United States and European colonial powers, entering World War II as an Axis power . After suffering defeat in
15088-638: The free metal . It is obtained industrially by mining bauxite , a sedimentary rock rich in aluminium minerals. The discovery of aluminium was announced in 1825 by Danish physicist Hans Christian Ørsted . The first industrial production of aluminium was initiated by French chemist Henri Étienne Sainte-Claire Deville in 1856. Aluminium became much more available to the public with the Hall–Héroult process developed independently by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886, and
15272-411: The head of government has the power to appoint and dismiss Ministers of State , and is appointed by the emperor after being designated from among the members of the Diet. Shigeru Ishiba is Japan's prime minister; he took office after winning the 2024 Liberal Democratic Party leadership election . The broadly conservative Liberal Democratic Party has been the dominant party in the country since
15456-551: The interstellar gas ; if the original Al were still present, gamma ray maps of the Milky Way would be brighter. Overall, the Earth is about 1.59% aluminium by mass (seventh in abundance by mass). Aluminium occurs in greater proportion in the Earth's crust than in the universe at large. This is because aluminium easily forms the oxide and becomes bound into rocks and stays in the Earth's crust , while less reactive metals sink to
15640-754: The samurai . In 1185, following the defeat of the Taira clan by the Minamoto clan in the Genpei War , samurai Minamoto no Yoritomo established a military government at Kamakura . After Yoritomo's death, the Hōjō clan came to power as regents for the shōgun . The Zen school of Buddhism was introduced from China in the Kamakura period (1185–1333) and became popular among the samurai class. The Kamakura shogunate repelled Mongol invasions in 1274 and 1281 but
15824-513: The 1923 Great Tokyo Earthquake , the passing of laws against political dissent , and a series of attempted coups . This process accelerated during the 1930s, spawning several radical nationalist groups that shared a hostility to liberal democracy and a dedication to expansion in Asia. In 1931, Japan invaded China and occupied Manchuria , which led to the establishment of puppet state of Manchukuo in 1932; following international condemnation of
16008-877: The 1940s, Firestone was given a defense contract to produce plastic helmet liners; while outproduced by Westinghouse Electric , they still made a fair amount for the M1 Helmet . On September 2, 1940, William Hoppmann, the General Manager of Firestone's Havana office was discharged from his position under the suspicion of being a Nazi agent. On October 11, 1941, a fire at the Firestone Rubber and Latex plant in Fall River, Massachusetts destroyed 5 out of its 8 buildings and destroyed at least 15,000 tons of rubber. The fire caused $ 12 million in damage (equivalent to $ 192 million in 2023). In 1951, Firestone
16192-664: The 1950s, often called the 1955 System . Historically influenced by Chinese law , the Japanese legal system developed independently during the Edo period through texts such as Kujikata Osadamegaki . Since the late 19th century, the judicial system has been largely based on the civil law of Europe, notably Germany. In 1896, Japan established a civil code based on the German Bürgerliches Gesetzbuch , which remains in effect with post–World War II modifications. The Constitution of Japan , adopted in 1947,
16376-425: The 500's debut, Thomas A. Robertson, Firestone's director of development, wrote an internal memo stating "We are making an inferior quality radial tire which will subject us to belt–edge separation at high mileage". Firestone introduced strict quality control measures in an attempt to fix the inherent problems, however they were not successful in eliminating the basic faults. In 1977 a recall of 400,000 tires produced at
16560-557: The 500, a recall, involving seven million tires. The report went on to indicate that Ford also had been complicit, stating that The Ford Motor Company had instructed Firestone to add a nylon ply to the tires it manufactured in Venezuela for additional strength and that Ford had made suspension changes to the Explorer model available in Venezuela. Ford did not specify adding the nylon ply for U.S.-made Firestone tires nor did it change
16744-526: The 5th century BCE. The ancients are known to have used alum as a dyeing mordant and for city defense. After the Crusades , alum, an indispensable good in the European fabric industry, was a subject of international commerce; it was imported to Europe from the eastern Mediterranean until the mid-15th century. The nature of alum remained unknown. Around 1530, Swiss physician Paracelsus suggested alum
16928-472: The Al–Zn–Mg class. Aluminium has a high chemical affinity to oxygen, which renders it suitable for use as a reducing agent in the thermite reaction. A fine powder of aluminium reacts explosively on contact with liquid oxygen ; under normal conditions, however, aluminium forms a thin oxide layer (~5 nm at room temperature) that protects the metal from further corrosion by oxygen, water, or dilute acid,
17112-467: The Explorer suspension on U.S. models at this time. An abnormally high failure rate in Firestone's Wilderness AT, Firestone ATX, and ATX II tires resulted in multiple lawsuits, as well as an eventual mandatory recall. In 2001 Bridgestone/Firestone severed its ties to Ford citing a lack of trust. The lack of trust stemmed from concerns that Ford had not heeded warnings by Bridgestone/Firestone relating to
17296-694: The Fuzion brand name. Fuzion is a tire manufactured in China for Bridgestone/ Firestone as a budget replacement tire. Makes include the Fuzion UHP Sport A/S, SUV, and Touring.

The Firearm and Sword Possession Control Law strictly regulates
17664-589: The Pacific Ring of Fire , making its islands prone to destructive earthquakes and tsunamis . The first known habitation of the archipelago dates to the Upper Paleolithic , with the beginning Japanese Paleolithic dating to c. 36,000 BC . Between the fourth and sixth centuries, its kingdoms were united under an emperor in Nara , and later Heian-kyō . From the 12th century, actual power
17848-624: The Pacific . Throughout areas occupied by Japan during the war, numerous abuses were committed against local inhabitants, with many forced into sexual slavery . After Allied victories during the next four years, which culminated in the Soviet invasion of Manchuria and the atomic bombings of Hiroshima and Nagasaki in 1945, Japan agreed to an unconditional surrender . The war cost Japan millions of lives and its colonies , including de jure parts of Japan such as Korea , Taiwan , Karafuto , and
18032-646: The South Gate plant was closed in 1980 and 1,300 workers were laid off. East Los Angeles College has proposed a new satellite campus at the site. In 1928, the company built a factory in Brentford, England , a longtime Art Deco landmark on a major route into the city; this closed in 1979. After its purchase by Trafalgar House , the building was demolished during the August 1980 bank holiday weekend, reportedly in anticipation of its becoming listed . In 1936,
18216-417: The United States (9.9 percent), and Australia (9.8 percent). Japan's main imports are machinery and equipment, fossil fuels, foodstuffs, chemicals, and raw materials for its industries. The Japanese variant of capitalism has many distinct features: keiretsu enterprises are influential, and lifetime employment and seniority-based career advancement are common in the Japanese work environment . Japan has
18400-418: The United States dollar, and alumina prices. The BRIC countries' combined share in primary production and primary consumption grew substantially in the first decade of the 21st century. China is accumulating an especially large share of the world's production thanks to an abundance of resources, cheap energy, and governmental stimuli; it also increased its consumption share from 2% in 1972 to 40% in 2010. In
18584-462: The United States, Western Europe, and Japan, most aluminium was consumed in transportation, engineering, construction, and packaging. In 2021, prices for industrial metals such as aluminium have soared to near-record levels as energy shortages in China drive up costs for electricity. The names aluminium and aluminum are derived from the word alumine , an obsolete term for alumina , the primary naturally occurring oxide of aluminium . Alumine
18768-578: The aluminium atoms have tetrahedral four-coordination and the other half have trigonal bipyramidal five-coordination. Four pnictides – aluminium nitride (AlN), aluminium phosphide (AlP), aluminium arsenide (AlAs), and aluminium antimonide (AlSb) – are known. They are all III-V semiconductors isoelectronic to silicon and germanium , all of which but AlN have the zinc blende structure. All four can be made by high-temperature (and possibly high-pressure) direct reaction of their component elements. Aluminium alloys well with most other metals (with
18952-476: The capital, settling on Heian-kyō (modern-day Kyoto ) in 794. This marked the beginning of the Heian period (794–1185), during which a distinctly indigenous Japanese culture emerged. Murasaki Shikibu 's The Tale of Genji and the lyrics of Japan's national anthem " Kimigayo " were written during this time. Japan's feudal era was characterized by the emergence and dominance of a ruling class of warriors,
19136-436: The characteristic physical properties of a post-transition metal, with longer-than-expected interatomic distances. Furthermore, as Al is a small and highly charged cation, it is strongly polarizing and bonding in aluminium compounds tends towards covalency ; this behavior is similar to that of beryllium (Be ), and the two display an example of a diagonal relationship . The underlying core under aluminium's valence shell
19320-550: The civilian ownership of guns, swords, and other weaponry. According to the United Nations Office on Drugs and Crime , among the member states of the UN that report statistics as of 2018 , the incidence rates of violent crimes such as murder, abduction, sexual violence, and robbery are very low in Japan. Japanese society traditionally places a strong emphasis on collective harmony and conformity , which has led to
19504-591: The company had paid $ 2.3 million in taxes to the Taylor government (equivalent to $ 4.49 million in 2023), which some say helped legitimize Taylor's Greater Liberia government and finance and enable its attack on ECOMOG controlled Monrovia. Operations did not fully restart until 2003 at the conclusion of the Second Liberian Civil War . Since the end of the war, Firestone has invested over $ 100 million in restoring and rebuilding its facilities in Liberia. The company's ventures in Liberia have been
19688-521: The company opened a plant in Memphis, Tennessee . With a work force exceeding 3,000 employees, the Memphis plant was the largest tire manufacturer in the company's worldwide operation. On July 1, 1963, the company celebrated the production of 100 million tires in Memphis. The Memphis plant closed in 1982, and most of the plant buildings were demolished. The EPA considers the tract a brownfield site , and
19872-622: The company opened one of the world's largest rubber plantations , extending over one million acres (1,560 sq mi; 4,050 km), in Liberia, West Africa . That year the company also opened its first Firestone Tire and Service Center (later renamed Firestone Complete Auto Care). Firestone Complete Auto Care is the division of Firestone that offers automotive maintenance and repair, including tires. In 1927, Henry Ford and Harvey S. Firestone visited Southern California to select locations for new factories. His friends said Ford wanted to be near
20056-677: The company opened the Bridgestone Americas Technology Center. Firestone Complete Auto Care is an chain of automotive maintenance shops founded in Nashville, Tennessee in 1926. There are over 2,300 Complete Auto Care locations in the United States, all of them independently owned by Firestone, with about 20 million customers each year as of 2002. At the start of 2022 Bridgestone, parent company of Firestone, announced that it will expand its hybrid and electric vehicular services The Indianapolis 500 auto race
20240-487: The company to the Japanese company Bridgestone , which was able to buy the company for much less than it had been worth a decade and a half earlier. The companies celebrated the 20th anniversary of the merger in 2008, and changed the name of the tire division to Bridgestone Americas Tire Operations, LLC. In 1972, Firestone received a ten-year import "concession" by the Kenyan government to secure Firestone's investment in
20424-476: The company's seventeen manufacturing plants, including six in one day, and relocated the company from its ancestral home in Akron, Ohio to Chicago, Illinois . He spun off non-tire related businesses, including the Firestone Country Club ; it was considered a deliberate plan to boost the stock price, and it paid off. In 1988, after discussions with Pirelli , Nevin negotiated the sale of
20608-418: The complaints, tested the tires and tried to assert that the tires had been abused or under-inflated. On September 6, 2000, in a statement before the U.S. Senate Appropriations Transportation subcommittee the president of the consumer advocacy group Public Citizen , Joan Claybrook , stated: ...There are a number of parallels between this recall in 2000 and the 1978 recall of the Firestone 500...there
20792-419: The coordination numbers are lower. The other trihalides are dimeric or polymeric with tetrahedral four-coordinate aluminium centers. Aluminium trichloride (AlCl 3 ) has a layered polymeric structure below its melting point of 192.4 °C (378 °F) but transforms on melting to Al 2 Cl 6 dimers. At higher temperatures those increasingly dissociate into trigonal planar AlCl 3 monomers similar to
20976-428: The core. In the Earth's crust, aluminium is the most abundant metallic element (8.23% by mass ) and the third most abundant of all elements (after oxygen and silicon). A large number of silicates in the Earth's crust contain aluminium. In contrast, the Earth's mantle is only 2.38% aluminium by mass. Aluminium also occurs in seawater at a concentration of 2 μg/kg. Because of its strong affinity for oxygen, aluminium
21160-474: The decay of Al was responsible for the melting and differentiation of some asteroids after their formation 4.55 billion years ago. The remaining isotopes of aluminium, with mass numbers ranging from 21 to 43, all have half-lives well under an hour. Three metastable states are known, all with half-lives under a minute. An aluminium atom has 13 electrons, arranged in an electron configuration of [ Ne ] 3s 3p , with three electrons beyond
21344-688: The design of the Ford Explorer. In 2006, Firestone announced renewed efforts to recall tires of the same model recalled in 2000 after the tires were linked to recent deaths and injuries. According to Firestone's last filing with the National Highway Transportation Administration, only 90,259 of more than 2.5 million recalled tires were confirmed as removed from service. In November 2013, two recalled Wilderness AT tires were found in Atlanta, Georgia. One of
21528-628: The emergence of a Japanese state centered on the Imperial Court in Heijō-kyō (modern Nara ). The period is characterized by the appearance of a nascent literary culture with the completion of the Kojiki (712) and Nihon Shoki (720), as well as the development of Buddhist-inspired artwork and architecture . A smallpox epidemic in 735–737 is believed to have killed as much as one-third of Japan's population. In 784, Emperor Kanmu moved
21712-399: The environment, no living organism is known to metabolize aluminium salts , but this aluminium is well tolerated by plants and animals. Because of the abundance of these salts, the potential for a biological role for them is of interest, and studies are ongoing. Of aluminium isotopes, only Al is stable. This situation is common for elements with an odd atomic number. It is
21896-678: The event of Cold War hostilities in Eastern Europe. Built in southern California, this missile was replaced in 1962 by the MGM-29 Sergeant system. In 1961, Firestone acquired the Dayton Tire division from the Dayco Corporation. Dayco later sued both Firestone and Goodyear , alleging that the two companies conspired to monopolize the tire industry in the United States. The United States District Court dismissed
22080-478: The exception of most alkali metals and group 13 metals) and over 150 intermetallics with other metals are known. Preparation involves heating fixed metals together in certain proportion, followed by gradual cooling and annealing . Bonding in them is predominantly metallic and the crystal structure primarily depends on efficiency of packing. There are few compounds with lower oxidation states. A few aluminium(I) compounds exist: AlF, AlCl, AlBr, and AlI exist in
22264-520: The fact that its nuclei are much lighter, while difference in the unit cell size does not compensate for this difference. The only lighter metals are the metals of groups 1 and 2 , which apart from beryllium and magnesium are too reactive for structural use (and beryllium is very toxic). Aluminium is not as strong or stiff as steel, but the low density makes up for this in the aerospace industry and for many other applications where light weight and relatively high strength are crucial. Pure aluminium
22448-761: The first time, initiating direct commercial and cultural exchange between Japan and the West. Oda Nobunaga used European technology and firearms to conquer many other daimyō ; his consolidation of power began what was known as the Azuchi–Momoyama period . After the death of Nobunaga in 1582, his successor, Toyotomi Hideyoshi , unified the nation in the early 1590s and launched two unsuccessful invasions of Korea in 1592 and 1597 . Tokugawa Ieyasu served as regent for Hideyoshi's son Toyotomi Hideyori and used his position to gain political and military support. When open war broke out, Ieyasu defeated rival clans in
22632-500: The former headquarters, tire plant, and technical center, houses 450 employees whose jobs are to develop innovative and advanced tire technologies for the company. In June 2022, Bridgestone opened up its $ 21 million Advanced Tire Production Center which replaced the Firestone Advance Tire Works Plant at the original Firestone Tire and Rubber Company headquarters which opened in 1910. The new building
22816-730: The gas phase after explosion and in stellar absorption spectra. More thoroughly investigated are compounds of the formula R 4 Al 2 which contain an Al–Al bond and where R is a large organic ligand . A variety of compounds of empirical formula AlR 3 and AlR 1.5 Cl 1.5 exist. The aluminium trialkyls and triaryls are reactive, volatile, and colorless liquids or low-melting solids. They catch fire spontaneously in air and react with water, thus necessitating precautions when handling them. They often form dimers, unlike their boron analogues, but this tendency diminishes for branched-chain alkyls (e.g. Pr , Bu , Me 3 CCH 2 ); for example, triisobutylaluminium exists as an equilibrium mixture of
23000-453: The gaseous phase when the respective trihalide is heated with aluminium, and at cryogenic temperatures. A stable derivative of aluminium monoiodide is the cyclic adduct formed with triethylamine , Al 4 I 4 (NEt 3 ) 4 . Al 2 O and Al 2 S also exist but are very unstable. Very simple aluminium(II) compounds are invoked or observed in the reactions of Al metal with oxidants. For example, aluminium monoxide , AlO, has been detected in
23184-415: The government and industrial corporations; as a result, environmental pollution was widespread in the 1950s and 1960s. Responding to rising concerns, the government introduced environmental protection laws in 1970. The oil crisis in 1973 also encouraged the efficient use of energy because of Japan's lack of natural resources. Japan ranks 20th in the 2018 Environmental Performance Index , which measures
23368-633: The government to increase spending by 65% until 2027. Recent tensions, particularly with North Korea and China, have reignited the debate over the status of the JSDF and its relation to Japanese society. Domestic security in Japan is provided mainly by the prefectural police departments , under the oversight of the National Police Agency . As the central coordinating body for the Prefectural Police Departments,
23552-646: The halides, nitrate , and sulfate . For similar reasons, anhydrous aluminium salts cannot be made by heating their "hydrates": hydrated aluminium chloride is in fact not AlCl 3 ·6H 2 O but [Al(H 2 O) 6 ]Cl 3 , and the Al–O bonds are so strong that heating is not sufficient to break them and form Al–Cl bonds instead: All four trihalides are well known. Unlike the structures of the three heavier trihalides, aluminium fluoride (AlF 3 ) features six-coordinate aluminium, which explains its involatility and insolubility as well as high heat of formation . Each aluminium atom
23736-578: The largest earthquakes in its recorded history - the Tōhoku earthquake - triggering the Fukushima Daiichi nuclear disaster . On May 1, 2019, after the historic abdication of Emperor Akihito , his son Naruhito became Emperor, beginning the Reiwa era. Japan comprises 14,125 islands extending along the Pacific coast of Asia. It stretches over 3000 km (1900 mi) northeast–southwest from
23920-607: The largest suppliers of automotive tires in North America for over 75 years. In 1906, Henry Ford chose Firestone to supply tires for its car models. In 1918, Firestone Tire and Rubber Company of Canada was incorporated in Hamilton, Ontario , and the first Canadian-made tire rolled off the line on September 15, 1922. During the 1920s, Firestone produced the Oldfield tire, named for racing driver Barney Oldfield . In 1926,
24104-554: The lawsuit. In 1965 Firestone acquired the Seiberling Rubber Company . In late 1979, Firestone brought in John Nevin, the ex-head of Zenith Electronics , as president to save the hemorrhaging company from total collapse. It was more than a billion dollars in debt at the time and losing $ 250 million a year (equivalent respectively to $ 3.39 billion and $ 847 million in 2023). Nevin closed nine of
24288-433: The low-pressure polymerization of ethene and propene . There are also some heterocyclic and cluster organoaluminium compounds involving Al–N bonds. The industrially most important aluminium hydride is lithium aluminium hydride (LiAlH 4 ), which is used as a reducing agent in organic chemistry . It can be produced from lithium hydride and aluminium trichloride . The simplest hydride, aluminium hydride or alane,
24472-512: The mass production of aluminium led to its extensive use in industry and everyday life. In the First and Second World Wars, aluminium was a crucial strategic resource for aviation . In 1954, aluminium became the most produced non-ferrous metal , surpassing copper . In the 21st century, most aluminium was consumed in transportation, engineering, construction, and packaging in the United States, Western Europe, and Japan. Despite its prevalence in
24656-529: The metal remained rare; its cost exceeded that of gold. The first industrial production of aluminium was established in 1856 by French chemist Henri Etienne Sainte-Claire Deville and companions. Deville had discovered that aluminium trichloride could be reduced by sodium, which was more convenient and less expensive than potassium, which Wöhler had used. Even then, aluminium was still not of great purity and produced aluminium differed in properties by sample. Because of its electricity-conducting capacity, aluminium
24840-600: The metal to be isolated from alum was alumium , which Davy suggested in an 1808 article on his electrochemical research, published in Philosophical Transactions of the Royal Society . It appeared that the name was created from the English word alum and the Latin suffix -ium ; but it was customary then to give elements names originating in Latin, so this name was not adopted universally. This name
25024-465: The metal with many uses at the time. During World War I , major governments demanded large shipments of aluminium for light strong airframes; during World War II , demand by major governments for aviation was even higher. By the mid-20th century, aluminium had become a part of everyday life and an essential component of housewares. In 1954, production of aluminium surpassed that of copper , historically second in production only to iron, making it
25208-491: The metal. Almost all metallic aluminium is produced from the ore bauxite (AlO x (OH) 3–2 x ). Bauxite occurs as a weathering product of low iron and silica bedrock in tropical climatic conditions. In 2017, most bauxite was mined in Australia, China, Guinea, and India. The history of aluminium has been shaped by usage of alum . The first written record of alum, made by Greek historian Herodotus , dates back to
25392-485: The monomer and dimer. These dimers, such as trimethylaluminium (Al 2 Me 6 ), usually feature tetrahedral Al centers formed by dimerization with some alkyl group bridging between both aluminium atoms. They are hard acids and react readily with ligands, forming adducts. In industry, they are mostly used in alkene insertion reactions, as discovered by Karl Ziegler , most importantly in "growth reactions" that form long-chain unbranched primary alkenes and alcohols, and in
25576-625: The most developed state in Asia and as an industrialized world power that pursued military conflict to expand its sphere of influence. After victories in the First Sino-Japanese War (1894–1895) and the Russo-Japanese War (1904–1905), Japan gained control of Taiwan, Korea and the southern half of Sakhalin , and annexed Korea in 1910. The Japanese population doubled from 35 million in 1873 to 70 million by 1935, with
25760-506: The most produced non-ferrous metal . During the mid-20th century, aluminium emerged as a civil engineering material, with building applications in both basic construction and interior finish work, and increasingly being used in military engineering, for both airplanes and land armor vehicle engines. Earth's first artificial satellite , launched in 1957, consisted of two separate aluminium semi-spheres joined and all subsequent space vehicles have used aluminium to some extent. The aluminium can
25944-546: The name as Giapan in a translation of a 1565 Portuguese letter. Modern humans arrived in Japan around 38,000 years ago (~36,000 BC), marking the beginning of the Japanese Paleolithic . This was followed from around 14,500 BC (the start of the Jōmon period ) by a Mesolithic to Neolithic semi-sedentary hunter-gatherer culture characterized by pit dwelling and rudimentary agriculture. Clay vessels from
26128-402: The new tire was performed on equipment designed to manufacture bias-ply tires. During the 1970s, Firestone experienced major problems with the Firestone 500 radial. The Firestone 500 steel-belted radials began to show signs of separation of the tread at high speeds. While the cause was never proved, it is believed that the failure of bonding cements, used by Firestone to hold the tread to
26312-614: The next decade, the -um spelling dominated American usage. In 1925, the American Chemical Society adopted this spelling. The International Union of Pure and Applied Chemistry (IUPAC) adopted aluminium as the standard international name for the element in 1990. In 1993, they recognized aluminum as an acceptable variant; the most recent 2005 edition of the IUPAC nomenclature of inorganic chemistry also acknowledges this spelling. IUPAC official publications use
26496-485: The northern islands. Japan has over 90,000 species of wildlife as of 2019 , including the brown bear , the Japanese macaque , the Japanese raccoon dog , the small Japanese field mouse , and the Japanese giant salamander . There are 53 Ramsar wetland sites in Japan. Five sites have been inscribed on the UNESCO World Heritage List for their outstanding natural value. In the period of rapid economic growth after World War II, environmental policies were downplayed by
26680-629: The occupation , it resigned from the League of Nations in 1933. In 1936, Japan signed the Anti-Comintern Pact with Nazi Germany ; the 1940 Tripartite Pact made it one of the Axis powers . The Empire of Japan invaded other parts of China in 1937, precipitating the Second Sino-Japanese War (1937–1945). In 1940, the Empire invaded French Indochina , after which the United States placed an oil embargo on Japan. On December 7–8, 1941, Japanese forces carried out surprise attacks on Pearl Harbor , as well as on British forces in Malaya , Singapore , and Hong Kong , among others, beginning World War II in
26864-487: The ocean and picked Long Beach and suggested Firestone locate in South Gate, California a small community southeast of downtown Los Angeles that at the time was mostly farmland. There Firestone identified 40 acres (16 ha) of beanfields for the site of his new manufacturing plant. Architects Curlett and Beelman designed a spectacular four-story Italianate -style complex, with its own power plant and decorated with polychrome murals by Gladding, McBean depicting
27048-429: The only primordial aluminium isotope, i.e. the only one that has existed on Earth in its current form since the formation of the planet. It is therefore a mononuclidic element and its standard atomic weight is virtually the same as that of the isotope. This makes aluminium very useful in nuclear magnetic resonance (NMR), as its single stable isotope has a high NMR sensitivity. The standard atomic weight of aluminium
27232-438: The onset of the dispute and subsiding when the dispute was finally settled at the end of 1996. Other similar plants of Firestone did not report similar increases in the defect rate in this period. Where the Rubber Meets the Road is an advertisement jingle that was frequently used in the 1960s and 1970s, especially on televised sporting events. The jingle was sung by Don Rondo . Bridgestone/Firestone also produces tires under
27416-550: The outbreak of the First Liberian Civil War in 1990, the Firestone Natural Rubber Company was the largest plantation of its kind in the world. It was originally envisioned for 350,000 people to be employed on the newly created plantations. However this was more than the number of able-bodied men in the entire nation at the time, which created intense pressure for labor. In the period between 1926 and 1946 Christine Whyte concluded that: The collusion between Firestone and government officials to keep wages low and coerce workers onto
27600-407: The oxidation state 3+. The coordination number of such compounds varies, but generally Al is either six- or four-coordinate. Almost all compounds of aluminium(III) are colorless. In aqueous solution, Al exists as the hexaaqua cation [Al(H 2 O) 6 ] , which has an approximate K a of 10 . Such solutions are acidic as this cation can act as a proton donor and progressively hydrolyze until
27784-460: The patents he filed between 1886 and 1903. It is unknown whether this spelling was introduced by mistake or intentionally, but Hall preferred aluminum since its introduction because it resembled platinum , the name of a prestigious metal. By 1890, both spellings had been common in the United States, the -ium spelling being slightly more common; by 1895, the situation had reversed; by 1900, aluminum had become twice as common as aluminium ; in
27968-410: The period are among the oldest surviving examples of pottery. The Japonic -speaking Yayoi people entered the archipelago from the Korean Peninsula, intermingling with the Jōmon ; the Yayoi period saw the introduction of practices including wet-rice farming , a new style of pottery , and metallurgy from China and Korea. According to legend, Emperor Jimmu (descendant of Amaterasu ) founded
28152-404: The planet. However, minute traces of Al are produced from argon in the atmosphere by spallation caused by cosmic ray protons. The ratio of Al to Be has been used for radiodating of geological processes over 10 to 10 year time scales, in particular transport, deposition, sediment storage, burial times, and erosion. Most meteorite scientists believe that the energy released by
28336-473: The plantations was at best substantially overlooked, at worst regarded as a form of "development" in itself. In September 1990, rebel NPFL forces (led by Charles Taylor , who would later be convicted of war crimes ) executed sitting Liberian president Samuel Doe and seized the Harbel plantation. Firestone had to evacuate its American workers as a result. In June 1991, Firestone sent a delegation to Monrovia in an attempt to restart operations in Harbel. After
28520-423: The possible presence of hazardous substances or contaminants have deterred its redevelopment . During World War II , the company was called on by the U.S. Government to make artillery shells , aluminum kegs for food transport, and rubberized military products. Barrage balloons were produced at Akron. Firestone ranked 55th among U.S. corporations in the value of wartime military production contracts. In
28704-425: The problematic Decatur, Illinois plant was initiated. Firestone blamed the problems on the consumer, stating underinflation and poor maintenance. On October 20, 1978, Firestone recalled over 7 million Firestone 500 tires, the largest tire recall to date. Congressional hearings into the 500 also took place in 1978. The tire was found to be defective and the cause of 250 deaths. In May 1980 after finding that they knew
28888-423: The respective hydrogen chalcogenide . As aluminium is a small atom relative to these chalcogens, these have four-coordinate tetrahedral aluminium with various polymorphs having structures related to wurtzite , with two-thirds of the possible metal sites occupied either in an orderly (α) or random (β) fashion; the sulfide also has a γ form related to γ-alumina, and an unusual high-temperature hexagonal form where half
29072-485: The scale of the economies. However, the need to exploit lower-grade poorer quality deposits and the use of fast increasing input costs (above all, energy) increased the net cost of aluminium; the real price began to grow in the 1970s with the rise of energy cost. Production moved from the industrialized countries to countries where production was cheaper. Production costs in the late 20th century changed because of advances in technology, lower energy prices, exchange rates of
29256-408: The structure of BCl 3 . Aluminium tribromide and aluminium triiodide form Al 2 X 6 dimers in all three phases and hence do not show such significant changes of properties upon phase change. These materials are prepared by treating aluminium with the halogen. The aluminium trihalides form many addition compounds or complexes; their Lewis acidic nature makes them useful as catalysts for
29440-402: The study of Japan by the Japanese. The United States Navy sent Commodore Matthew C. Perry to force the opening of Japan to the outside world. Arriving at Uraga with four " Black Ships " in July 1853, the Perry Expedition resulted in the March 1854 Convention of Kanagawa . Subsequent similar treaties with other Western countries brought economic and political crises. The resignation of
29624-527: The subject of considerable scrutiny and criticism, including a 2005 Alien Tort Claims Act case brought in California by the International Labor Rights Fund and a 2014 investigative report by ProPublica entitled "Firestone and the Warlord", and a PBS Frontline documentary by the same name. In 1996, several state agencies in Arizona began experiencing major issues with Firestone tires on Ford Explorers. According to news reports, various agencies demanded new tires, and Firestone conducted an investigation of
29808-578: The suppression of individual rights . Japan's constitution prohibits racial and religious discrimination, and the country is a signatory to numerous international human rights treaties. However, it lacks any laws against discrimination based on race, ethnicity, religion, sexual orientation, or gender identity and does not have a national human rights institution. Japan has faced criticism for its gender inequality , not allowing same-sex marriages , use of racial profiling by police, and allowing capital punishment . Other human rights issues include
29992-537: The tire and rubber-making process. A year after the plant opened in 1928, it expanded to double the initial size, and by 1954 grew to nearly one million square feet (23 acres; 9.3 ha). The town grew around Firestone, its main boulevard was named after Harvey, and Los Angeles became the number one tire market in the country. By the mid-1970s, Ford and General Motors had massive layoffs as Firestone and other manufacturers opened new plants in non-union locales like Wilson, North Carolina . After considerable downsizing,
30176-447: The tire carcass, may have allowed water to penetrate the tire, which in turn may have caused the internal steel wire to corrode. In March 1978, the U.S. National Highway Traffic Safety Administration (NHTSA) announced publicly a formal investigation into defects of the Firestone 500. The NHTSA investigation found that the tread separation problem was most probably a design defect affecting all Firestone 500s. In 1973, only two years after
30360-463: The tires was offered for sale as new at a used tire retail shop. Some outside observers have speculated about the blame worthiness of both parties. Firestone tires being prone to tread separation and failure, and the SUVs being especially prone to rolling over if a tire fails at speed compared to other vehicles. A subsequent NHTSA investigation of real world accident data showed that the Ford Explorer SUVs in question were no more likely to roll over after
30544-458: The tires were defective, the NHTSA fined Firestone $ 500,000 (equivalent to $ 1.55 million in 2023), which at that time was the largest fine imposed on any U.S. corporation and the largest civil penalty imposed since passage of the 1966 National Traffic and Motor Vehicle Act. Multiple lawsuits were settled out of court and the constant negative publicity crippled the company's sales and share price. Harvard Business School and Wharton School of
30728-403: The treatment of marginalized groups, such as ethnic minorities , refugees and asylum seekers . Japan has the world's fourth-largest economy by nominal GDP , after that of the United States, China and Germany; and the fifth-largest economy by PPP-adjusted GDP . As of 2021 , Japan's labor force is the world's eighth-largest , consisting of over 68.6 million workers. As of 2022 , Japan has
30912-536: The two therefore look similar. Aluminium is also good at reflecting solar radiation , although prolonged exposure to sunlight in air adds wear to the surface of the metal; this may be prevented if aluminium is anodized , which adds a protective layer of oxide on the surface. The density of aluminium is 2.70 g/cm , about 1/3 that of steel, much lower than other commonly encountered metals, making aluminium parts easily identifiable through their lightness. Aluminium's low density compared to most other metals arises from
31096-416: The world in 2019 for inbound tourism . The 2021 Travel and Tourism Competitiveness Report ranked Japan first in the world out of 117 countries. Its international tourism receipts in 2019 amounted to $ 46.1 billion. The Japanese agricultural sector accounts for about 1.2% of the country's total GDP as of 2018 . Only 11.5% of Japan's land is suitable for cultivation. Because of this lack of arable land,
31280-569: The world's strongest militaries . A developed country with one of the world's largest economies by nominal GDP , Japan is a global leader in science and technology and the automotive , robotics , and electronics industries . It has one of the world's highest life expectancies , though it is undergoing a population decline . Japan's culture is well known around the world, including its art , cuisine , film , music , and popular culture , which includes prominent comics , animation , and video game industries. The name for Japan in Japanese
31464-405: Was a documented coverup by Firestone of the 500 defect, spurred by the lack of a Firestone replacement tire. When the coverup was disclosed, the top management of the company was replaced as Firestone was severely damaged in reputation and economically. But a key difference is that the Firestone 500 was used on passenger cars, which rarely rolled over with tire failure. NHTSA documented 41 deaths with
31648-461: Was a salt of an earth of alum. In 1595, German doctor and chemist Andreas Libavius experimentally confirmed this. In 1722, German chemist Friedrich Hoffmann announced his belief that the base of alum was a distinct earth. In 1754, German chemist Andreas Sigismund Marggraf synthesized alumina by boiling clay in sulfuric acid and subsequently adding potash . Attempts to produce aluminium date back to 1760. The first successful attempt, however,
31832-424: Was borrowed from French, which in turn derived it from alumen , the classical Latin name for alum , the mineral from which it was collected. The Latin word alumen stems from the Proto-Indo-European root *alu- meaning "bitter" or "beer". British chemist Humphry Davy , who performed a number of experiments aimed to isolate the metal, is credited as the person who named the element. The first name proposed for
32016-422: Was completed in 1824 by Danish physicist and chemist Hans Christian Ørsted . He reacted anhydrous aluminium chloride with potassium amalgam , yielding a lump of metal looking similar to tin. He presented his results and demonstrated a sample of the new metal in 1825. In 1827, German chemist Friedrich Wöhler repeated Ørsted's experiments but did not identify any aluminium. (The reason for this inconsistency
32200-443: Was criticized by contemporary chemists from France, Germany, and Sweden, who insisted the metal should be named for the oxide, alumina, from which it would be isolated. The English name alum does not come directly from Latin, whereas alumine / alumina obviously comes from the Latin word alumen (upon declension , alumen changes to alumin- ). One example was Essai sur la Nomenclature chimique (July 1811), written in French by
32384-425: Was eventually overthrown by Emperor Go-Daigo . Go-Daigo was defeated by Ashikaga Takauji in 1336, beginning the Muromachi period (1336–1573). The succeeding Ashikaga shogunate failed to control the feudal warlords ( daimyō ) and a civil war began in 1467 , opening the century-long Sengoku period ("Warring States"). During the 16th century, Portuguese traders and Jesuit missionaries reached Japan for
32568-427: Was given the defense contract for the MGM-5 Corporal missile . Firestone was given a total of US$ 6,888,796 (equivalent to $ 64.8 million in 2023) for the first 200 units. Known as the "Embryo of the Army," it was a surface-to-surface guided missile which could deliver a high-explosive warhead up to 75 nautical miles (140 km). It was later modified to be able to carry a nuclear payload for use in
32752-413: Was held by military dictators ( shōgun ) and feudal lords ( daimyō ), and enforced by warrior nobility ( samurai ). After rule by the Kamakura and Ashikaga shogunates and a century of warring states , Japan was unified in 1600 by the Tokugawa shogunate , which implemented an isolationist foreign policy . In 1853, a United States fleet forced Japan to open trade to the West , which led to
32936-418: Was invented in 1956 and employed as a storage for drinks in 1958. Throughout the 20th century, the production of aluminium rose rapidly: while the world production of aluminium in 1900 was 6,800 metric tons, the annual production first exceeded 100,000 metric tons in 1916; 1,000,000 tons in 1941; 10,000,000 tons in 1971. In the 1970s, the increased demand for aluminium made it an exchange commodity; it entered
33120-433: Was only discovered in 1921.) He conducted a similar experiment in the same year by mixing anhydrous aluminium chloride with potassium and produced a powder of aluminium. In 1845, he was able to produce small pieces of the metal and described some physical properties of this metal. For many years thereafter, Wöhler was credited as the discoverer of aluminium. As Wöhler's method could not yield great quantities of aluminium,
33304-405: Was recorded on July 23, 2018, and repeated on August 17, 2020. Japan has nine forest ecoregions which reflect the climate and geography of the islands. They range from subtropical moist broadleaf forests in the Ryūkyū and Bonin Islands , to temperate broadleaf and mixed forests in the mild climate regions of the main islands, to temperate coniferous forests in the cold, winter portions of
33488-431: Was the world's fifth-largest exporter and fourth-largest importer in 2022. Its exports amounted to 18.2% of its total GDP in 2021. As of 2022 , Japan's main export markets were China (23.9 percent, including Hong Kong) and the United States (18.5 percent). Its main exports are motor vehicles, iron and steel products, semiconductors, and auto parts. Japan's main import markets as of 2022 were China (21.1 percent),
33672-510: Was used as the cap of the Washington Monument , completed in 1885. The tallest building in the world at the time, the non-corroding metal cap was intended to serve as a lightning rod peak. The first industrial large-scale production method was independently developed in 1886 by French engineer Paul Héroult and American engineer Charles Martin Hall ; it is now known as the Hall–Héroult process . The Hall–Héroult process converts alumina into metal. Austrian chemist Carl Joseph Bayer discovered
33856-531: Was won in 1911 by a car running Firestone tires, as did all winners of the race from 1920 to 1966 . The company also provided tires to NASCAR from 1948 to 1974, and to Formula One from 1950 to 1974. Citing rising costs as the cause, Firestone announced its withdrawal from professional motorsports in August 1974 with the exception of Formula 5000 and Formula One. The change was forecast to reduce Firestone's annual race testing budget from between $ 6 and $ 8 million to around $ 500,000 (in 2023, roughly equivalent to
