His mission won over the monarch, who embraced the faith and propagated it throughout the Sinhalese population . Succeeding kingdoms of Sri Lanka would maintain many Buddhist schools and monasteries and support the propagation of Buddhism into other countries in Southeast Asia. Sri Lankan Bhikkhus studied in India's famous ancient Buddhist University of Nalanda , which
670-430: A severe economic crisis occurred caused by rapidly increasing foreign debt, massive government budget deficits due to tax cuts, falling foreign remittances, a food crisis caused by mandatory organic farming along with a ban on chemical fertilizers, and a multitude of other factors. The Sri Lankan Government officially declared the ongoing crisis to be the worst economic crisis in the country in 73 years. In August 2021,

In 1851, Samuel Martin Kier began selling lamp oil to local miners, under the name "Carbon Oil". He distilled this from crude oil by a process of his own invention. He also invented a new lamp to burn his product. He has been dubbed
1072-468: A fledgling Tamil militancy in the north during the 1970s. The policy of standardisation by the Sirimavo government to rectify disparities created in university enrolment, which was in essence an affirmative action to assist geographically disadvantaged students to obtain tertiary education, resulted in reducing the proportion of Tamil students at university level and acted as the immediate catalyst for
1206-516: A food emergency was declared. In June 2022, Prime Minister Ranil Wickremesinghe declared the collapse of the Sri Lankan economy in parliament. The crisis resulted in Sri Lanka defaulting on its $ 51 billion sovereign debt for the first time in its history, along with double-digit inflation, a crippling energy crisis that led to approximately 15 hour power cuts, severe fuel shortages leading to
1340-622: A great deal of public excitement and investment drilling in new wells, not only in Pennsylvania, but also in Canada, where petroleum had been discovered at Oil Springs, Ontario in 1858, and southern Poland, where Ignacy Łukasiewicz had been distilling lamp oil from petroleum seeps since 1852. The increased supply of petroleum allowed oil refiners to entirely side-step the oil-from-coal patents of both Young and Gesner, and produce illuminating oil from petroleum without paying royalties to anyone. As

JP-8 is also used by the U.S. military and its NATO allies as a fuel for heaters, stoves, tanks, and as a replacement for diesel fuel in the engines of nearly all tactical ground vehicles and electrical generators. Aliphatic kerosene is a type of kerosene which has a low aromatic hydrocarbon content,
1742-434: A local petroleum seep . Many people knew of his work, but paid little attention to it. On the night of 31 July 1853, doctors at the local hospital needed to perform an emergency operation, virtually impossible by candlelight. They therefore sent a messenger for Łukasiewicz and his new lamps. The lamp burned so brightly and cleanly that the hospital officials ordered several lamps plus a large supply of fuel. Łukasiewicz realized
1876-540: A major political and environmental consequence. The Indian government subsidizes the fuel to keep the price very low, to around 15 U.S. cents per liter as of February 2007, as lower prices discourage dismantling of forests for cooking fuel. In Nigeria an attempt by the government to remove a fuel subsidy that includes kerosene met with strong opposition. Kerosene is used as a fuel in portable stoves , especially in Primus stoves invented in 1892. Portable kerosene stoves earn

The Ministry of Defence organized funeral in 2006, but declined to perform the requested DNA testing. Although it had stated that it abides by the Third Geneva Convention for the treatment of prisoners of war , it has been accused of mass execution and torture of captured soldiers in
2144-610: A member of the United Nations and the Commonwealth of Nations . In antiquity, Sri Lanka was known to travellers by a variety of names. According to the Mahāvaṃsa , the legendary Prince Vijaya named the island Tambapaṇṇĩ (" copper-red hands" or "copper-red earth"), because his followers' hands were reddened by the red soil of the area where he landed. In Hindu mythology , the term Lankā ("Island") appears but it

With the path clear towards
2680-527: A number of organisations, the Sri Lankan government announced in 2011 a plan to rename all those over which it has authority. The pre-history of Sri Lanka goes back 125,000 years and possibly even as far back as 500,000 years. The era spans the Palaeolithic , Mesolithic , and early Iron Ages . Among the Paleolithic human settlements discovered in Sri Lanka, Pahiyangala (37,000 BP), named after
2814-418: A number of useful liquids from it, one of which he named paraffine oil because at low temperatures, it congealed into a substance that resembled paraffin wax. Young took out a patent on his process and the resulting products in 1850, and built the first truly commercial oil-works in the world at Bathgate in 1851, using oil extracted from locally mined torbanite, shale, and bituminous coal. In 1852, he took out

Kerosene smoke contains high levels of harmful particulate matter , and household use of kerosene is associated with higher risks of cancer , respiratory infections, asthma , tuberculosis , cataracts , and adverse pregnancy outcomes. Kerosene is a low- viscosity , clear liquid formed from hydrocarbons obtained from
3216-505: A public demonstration in Charlottetown , Prince Edward Island of a new process he had discovered. He heated coal in a retort , and distilled from it a clear, thin fluid that he showed made an excellent lamp fuel. He coined the name "kerosene" for his fuel, a contraction of keroselaion , meaning wax-oil . The cost of extracting kerosene from coal was high. Gesner recalled from his extensive knowledge of New Brunswick 's geology
3350-438: A reputation of reliable and durable stove in everyday use, and perform especially well under adverse conditions. In outdoor activities and mountaineering, a decisive advantage of pressurized kerosene stoves over gas cartridge stoves is their particularly high thermal output and their ability to operate at very low temperature in winter or at high altitude. Wick stoves like Perfection's or wickless like Boss continue to be used by
3484-426: A result of the depression of 1847 stalled economic development and prompted the governor to introduce a series of taxes on firearms, dogs, shops, boats, etc., and to reintroduce a form of rajakariya , requiring six days free labour on roads or payment of a cash equivalent. These harsh measures antagonised the locals, and another rebellion broke out in 1848. A devastating leaf disease, Hemileia vastatrix , struck
3618-436: A result, the illuminating oil industry in the United States completely switched over to petroleum in the 1860s. The petroleum-based illuminating oil was widely sold as Kerosene, and the trade name soon lost its proprietary status, and became the lower-case generic product "kerosene". Because Gesner's original Kerosene had been also known as "coal oil", generic kerosene from petroleum was commonly called "coal oil" in some parts of

Among the villagers who survived the massacre were 28 individuals who were severely injured and they stated that the soldiers had attacked them with axes. Children as young as 3 and 6 years of age had axe injuries on their face. The Gonagala Massacre
9782-472: The areas they had captured, thereby violating the treaty they had signed in 1638. The Burgher people , a distinct ethnic group, emerged as a result of intermingling between the Dutch and native Sri Lankans in this period. The Kingdom of Kandy was the last independent monarchy of Sri Lanka. In 1595, Vimaladharmasurya brought the sacred Tooth Relic —the traditional symbol of royal and religious authority amongst
9916-424: The aromatic content of crude oil varies greatly from oil field to oil field. However by solvent extraction it is possible to separate aromatic hydrocarbons from aliphatic (alkane) hydrocarbons. A common method is solvent extraction with methanol, DMSO or sulfolane . Aromatic kerosene is a grade of kerosene with a large concentration of aromatic hydrocarbons, an example of this would be Exon 's Solvesso 150. Kerosene
10050-464: The arrival of Portuguese soldier and explorer Lourenço de Almeida , the son of Francisco de Almeida , in 1505. In 1517, the Portuguese built a fort at the port city of Colombo and gradually extended their control over the coastal areas. In 1592, after decades of intermittent warfare with the Portuguese, Vimaladharmasuriya I moved his kingdom to the inland city of Kandy , a location he thought more secure from attack. In 1619, succumbing to attacks by
10184-691: The battle site. The families’ previous inquiries at the Defense Ministry, the Sri Lankan Army, and the International Committee of the Red Cross for information on their sons’ fates had been fruitless. At the battlefield they learned that some 500 bodies had been piled together, doused with kerosene , and burnt on the spot by the Sri Lankan Army. Upon their return, a lawsuit was filed on the families’ behalf requesting
10318-481: The bill posed a grave concern for the Tamil community, which perceived in it a threat to their language and culture. The Federal Party (FP) launched a movement of non-violent resistance ( satyagraha ) against the bill, which prompted Bandaranaike to reach an agreement ( Bandaranaike–Chelvanayakam Pact ) with S. J. V. Chelvanayakam , leader of the FP, to resolve the looming ethnic conflict. The pact proved ineffective in
10452-443: The coffee plantations in 1869, destroying the entire industry within fifteen years. The British quickly found a replacement: abandoning coffee, they began cultivating tea instead. Tea production in Sri Lanka thrived in the following decades. Large-scale rubber plantations began in the early 20th century. By the end of the 19th century, a new educated social class transcending race and caste arose through British attempts to staff
10586-451: The compression ratio (making the engine less powerful and less efficient, but able to run on kerosene). The necessary equipment was sold under the trademark "Econom". During the fuel crisis of the 1970s , Saab-Valmet developed and series-produced the Saab 99 Petro that ran on kerosene, turpentine or gasoline. The project, codenamed "Project Lapponia", was headed by Simo Vuorio, and towards
10720-518: The conquest led by king Parâkramabâhu VI 's adopted son, Prince Sapumal . He ruled the North from 1450 to 1467 CE. The next three centuries starting from 1215 were marked by kaleidoscopically shifting collections of capitals in south and central Sri Lanka, including Dambadeniya, Yapahuwa , Gampola , Raigama , Kotte , Sitawaka , and finally, Kandy . In 1247, the Malay kingdom of Tambralinga which
10854-477: The country based on the rule of law and amalgamated the Kandyan and maritime provinces as a single unit of government. An executive council and a legislative council were established, later becoming the foundation of a representative legislature. By this time, experiments with coffee plantations were largely successful. Soon, coffee became the primary commodity export of Sri Lanka. Falling coffee prices as
10988-451: The country for the first time in over a century. Upon his request, ordained monks were sent from Burma to Sri Lanka to re-establish Buddhism, which had almost disappeared from the country during the Chola reign. During the medieval period, Sri Lanka was divided into three sub-territories, namely, Ruhunu , Pihiti and Maya . Sri Lanka's irrigation system was extensively expanded during
11122-624: The course of the 26 year long conflict. 2019 Sri Lanka Easter bombings carried out by the terrorist group National Thowheeth Jama'ath on 21 April 2019 resulted in the brutal death of 261 innocent people. On 26 April 2019 an anti terrorist operation was carried out against the National Thowheeth Jama'ath by the Sri Lanka Army with the operation being successful and National Thowheeth Jama'ath's insurgency ending. Economic troubles in Sri Lanka began in 2019, when
11256-595: The danger of not writing it down so that even if some of the monks whose duty it was to study and remember parts of the Canon for later generations died, the teachings would not be lost. After the council, palm-leaf manuscripts containing the completed Canon were taken to other countries such as Burma , Thailand , Cambodia and Laos . Sri Lanka was the first Asian country known to have a female ruler: Anula of Anuradhapura (r. 47–42 BCE). Sri Lankan monarchs undertook some remarkable construction projects such as Sigiriya ,
11390-411: The days of electrically lighted road barriers, highway construction zones were marked at night by kerosene fired, pot-bellied torches. Most of these uses of kerosene created thick black smoke because of the low temperature of combustion. A notable exception, discovered in the early 19th century, is the use of a gas mantle mounted above the wick on a kerosene lamp. Looking like a delicate woven bag above
11524-562: The distillation products appears to have been superior to Young's, resulting in a cleaner and better-smelling fuel. Manufacture of kerosene under the Gesner patents began in New York in 1854 and later in Boston —being distilled from bituminous coal and oil shale . Gesner registered the word "Kerosene" as a trademark in 1854, and for several years, only the North American Gas Light Company and
11658-530: The early 1900s, but the first case was documented in 1906. In 1919, major Sinhalese and Tamil political organisations united to form the Ceylon National Congress, under the leadership of Ponnambalam Arunachalam , pressing colonial masters for more constitutional reforms. But without massive popular support, and with the governor's encouragement for "communal representation" by creating a "Colombo seat" that dangled between Sinhalese and Tamils,
11792-618: The eldest son of the southern regional sub-king, Kavan Tissa , defeated Elara in the Battle of Vijithapura . During its two and a half millennia of existence, the Sinhala kingdom was invaded at least eight times by neighbouring South Indian dynasties such as the Chola , Pandya , and Pallava . There also were incursions by the kingdoms of Kalinga (modern Odisha ) and from the Malay Peninsula as well. The Fourth Theravāda Council
11926-521: The end of the 1970s, a working prototype was produced based on the Saab 99 GL. The car was designed to run on two fuels. Gasoline was used for cold starts and when extra power was needed, but normally it ran on kerosene or turpentine. The idea was that the gasoline could be made from peat using the Fischer–Tropsch process . Between 1980 and 1984, 3,756 Saab 99 Petros and 2,385 Talbot Horizons (a version of
12060-484: The engine reaches optimum operating temperature . Multiple fuel Evinrude and Mercury Racing engines also burn kerosene, as well as jet fuel. Today, kerosene is mainly used in fuel for jet engines in several grades. One highly refined form of the fuel is known as RP-1 , and is often burned with liquid oxygen as rocket fuel . These fuel grade kerosenes meet specifications for smoke points and freeze points . The combustion reaction can be approximated as follows, with
12194-445: The establishment of the Anuradhapura kingdom in 380 BCE during the reign of Pandukabhaya . Thereafter, Anuradhapura served as the capital city of the country for nearly 1,400 years. Ancient Sri Lankans excelled at building certain types of structures such as tanks , dagobas and palaces. Society underwent a major transformation during the reign of Devanampiya Tissa , with the arrival of Buddhism from India. In 250 BCE, Mahinda ,
12328-542: The face of ongoing protests by opposition and the Buddhist clergy. The bill, together with various government colonisation schemes , contributed much towards the political rancour between Sinhalese and Tamil political leaders. Bandaranaike was assassinated by an extremist Buddhist monk in 1959. Sirimavo Bandaranaike , the widow of Bandaranaike, took office as prime minister in 1960, and withstood an attempted coup d'état in 1962. During her second term as prime minister,
12462-415: The first South Asian country to liberalise its economy. Beginning in 1983 , ethnic tensions were manifested in an on-and-off insurgency against the government by the LTTE. An LTTE attack on 13 soldiers resulted in the start of a civil war, and in response anti-Tamil race riots took place, allegedly backed by Sinhalese hard-line ministers, which resulted in more than 150,000 Tamil civilians fleeing
12596-600: The first Sri Lankan president to resign in the middle of his term. On the same day the President's House was stormed, protesters besieged and stormed the private residence of the prime minister and burnt it down. After winning the 2022 Sri Lankan presidential election , on 21 July 2022, Ranil Wickremesinghe took oath as the ninth President of Sri Lanka. He implemented various economic reforms in efforts to stabilize Sri Lanka's economy, which has shown slight improvement since. On 23 September 2024, Anura Kumara Dissanayake
12730-455: The fleet had dropped to 167 ships. The Civil War cut into American whaling temporarily, but only 105 whaling ships returned to sea in 1866, the first full year of peace, and that number dwindled until only 39 American ships set out to hunt whales in 1876. Kerosene, made first from coal and oil shale, then from petroleum, had largely taken over whaling's lucrative market in lamp oil. Electric lighting started displacing kerosene as an illuminant in
12864-528: The government instituted socialist economic policies, strengthening ties with the Soviet Union and China, while promoting a policy of non-alignment. In 1971, Ceylon experienced a Marxist insurrection , which was quickly suppressed. In 1972, the country became a republic named Sri Lanka, repudiating its dominion status. Prolonged minority grievances and the use of communal emotionalism as an election campaign weapon by both Sinhalese and Tamil leaders abetted
12998-625: The government resumed fighting in 2006, and the government officially backed out of the ceasefire in 2008. In 2009, under the Presidency of Mahinda Rajapaksa , the Sri Lanka Armed Forces defeated the LTTE, bringing an end to the 26 year long civil war on 19 May 2009, and re-established control of the entire country by the Sri Lankan Government. Overall, between 60,000 and 100,000 people were killed during
13132-483: The heavier hydrocarbons that previously went into kerosene were incorporated into diesel fuel. Kerosene kept some market share by being increasingly used in stoves and portable heaters. A pilot project by ETH Zurich used solar power to produce kerosene from carbon dioxide and water in July 2022. The product can be used in existing aviation applications, and "can also be blended with fossil-derived kerosene." Kerosene
13266-483: The intake pipe, heating the kerosene to the point where it was vaporized and could be ignited by an electric spark . In Europe following the Second World War, automobiles were similarly modified to run on kerosene rather than gasoline, which they would have to import and pay heavy taxes on. Besides additional piping and the switch between fuels, the head gasket was replaced by a much thicker one to diminish
13400-550: The island's history. Other long-established groups include the Moors , Indian Tamils , Burghers , Malays , Chinese , and Vedda . Sri Lanka's documented history goes back 3,000 years, with evidence of prehistoric human settlements dating back 125,000 years. The earliest known Buddhist writings of Sri Lanka , known collectively as the Pali Canon , date to the fourth Buddhist council , which took place in 29 BCE. Also called
13534-766: The island, seeking asylum in other countries. Lapses in foreign policy resulted in India strengthening the Tigers by providing arms and training. In 1987, the Indo-Sri Lanka Accord was signed and the Indian Peace Keeping Force (IPKF) was deployed in northern Sri Lanka to stabilise the region by neutralising the LTTE. The same year, the JVP launched its second insurrection in Southern Sri Lanka, necessitating redeployment of
13668-482: The late 19th and early 20th centuries, kerosene space heaters were often built into kitchen ranges, and kept many farm and fishing families warm and dry through the winter. At one time, citrus growers used a smudge pot fueled by kerosene to create a pall of thick smoke over a grove in an effort to prevent freezing temperatures from damaging crops. " Salamanders " are kerosene space heaters used on construction sites to dry out building materials and to warm workers. Before
13802-461: The late 19th century, especially in urban areas. However, kerosene remained the predominant commercial end-use for petroleum refined in the United States until 1909, when it was exceeded by motor fuels. The rise of the gasoline-powered automobile in the early 20th century created a demand for the lighter hydrocarbon fractions, and refiners invented methods to increase their output of gasoline, while decreasing their output of kerosene. In addition, some of
13936-543: The leader of the political wing of the Tamil Tigers, accused the Sri Lankan Army of intentionally abandoning the bodies of nearly a thousand soldiers on the battlefields since May, despite the Tamils’ request that the Red Cross act as an intermediate. He told visiting relatives of missing servicemen that the military had only accepted 55 bodies to return to their families, while burying the rest with full military honors on
14070-827: The legislative council. In 1937, Tamil leader G. G. Ponnambalam demanded a 50–50 representation (50% for the Sinhalese and 50% for other ethnic groups) in the State Council. However, this demand was not met by the Soulbury reforms of 1944–45. The Soulbury constitution ushered in dominion status , with independence proclaimed on 4 February 1948. D. S. Senanayake became the first Prime Minister of Ceylon . Prominent Tamil leaders including Ponnambalam and Arunachalam Mahadeva joined his cabinet. The British Royal Navy remained stationed at Trincomalee until 1956. A countrywide popular demonstration against withdrawal of
14204-608: The local king Vira Alakesvara of Gampola . Zheng He captured King Vira Alakesvara and later released him. Zheng He erected the Galle Trilingual Inscription , a stone tablet at Galle written in three languages ( Chinese , Tamil , and Persian ), to commemorate his visit. The stele was discovered by S. H. Thomlin at Galle in 1911 and is now preserved in the Colombo National Museum . The early modern period of Sri Lanka begins with
14338-627: The molecular formula C 12 H 26 ( dodecane ): In the initial phase of liftoff, the Saturn V launch vehicle was powered by the reaction of liquid oxygen with RP-1. For the five 6.4 meganewton sea-level thrust F-1 rocket engines of the Saturn V, burning together, the reaction generated roughly 1.62 × 10 watts (J/s) (162 gigawatt) or 217 million horsepower. Kerosene is sometimes used as an additive in diesel fuel to prevent gelling or waxing in cold temperatures. Ultra-low sulfur kerosene
14472-414: The mountainous interior, in a bid to escape his power. Sri Lanka never really recovered from the effects of Kalinga Magha's invasion. King Vijayabâhu III, who led the resistance, brought the kingdom to Dambadeniya . The north, in the meanwhile, eventually evolved into the Jaffna kingdom . The Jaffna kingdom never came under the rule of any kingdom of the south except on one occasion; in 1450, following
14606-464: The parents of the missing soldiers. However, this was not the first time issues had arisen over reclamation of soldiers’ remains and the Army's responsiveness to the requests of families of missing soldiers for information regarding their fate. In April 2003, a group of parents of some of the 619 soldiers reported missing from a battle fought 27 September 1998 obtained permission from the LTTE to travel to
14740-534: The potential of his work and quit the pharmacy to find a business partner, and then traveled to Vienna to register his technique with the government. Łukasiewicz moved to the Gorlice region of Poland in 1854, and sank several wells across southern Poland over the following decade, setting up a refinery near Jasło in 1859. The petroleum discovery by Edwin Drake - Drake Well in western Pennsylvania in 1859 caused
14874-509: The radiolysis of TBP while the French nuclear industry tended to use diluents with very little aromatic content. The French nuclear reprocessing plants typically use TPH as their diluent. In recent times it has been shown by Mark Foreman at Chalmers that aliphatic kerosene can be replaced in solvent extraction with HVO100 which is a second generation biodiesel made by Neste . In X-ray crystallography , kerosene can be used to store crystals. When
15008-558: The reign of Parākramabāhu the Great (1153–1186). This period is considered as a time when Sri Lanka was at the height of its power. He built 1,470 reservoirs – the highest number by any ruler in Sri Lanka's history – repaired 165 dams, 3,910 canals, 163 major reservoirs, and 2,376 mini-reservoirs. His most famous construction is the Parakrama Samudra , the largest irrigation project of medieval Sri Lanka. Parākramabāhu's reign
15142-437: The rice rations resulted in the resignation of prime minister Dudley Senanayake . S. W. R. D. Bandaranaike was elected prime minister in 1956. His three-year rule had a profound influence through his self-proclaimed role of "defender of the besieged Sinhalese culture". He introduced the controversial Sinhala Only Act , recognising Sinhala as the only official language of the government. Although partially reversed in 1958,
15276-533: The right of "Unambuwe Bandara" , the crown passed to the brother of one of Narendrasinha's princesses, overlooking Narendrasinha's own son by a Sinhalese concubine . The new king was crowned Sri Vijaya Rajasinha later that year. Kings of the Nayakkar dynasty launched several attacks on Dutch controlled areas, which proved to be unsuccessful. During the Napoleonic Wars , fearing that French control of
15410-501: The rise of militancy. The assassination of Jaffna Mayor Alfred Duraiyappah in 1975 by the Liberation Tigers of Tamil Eelam (LTTE) marked a crisis point. The government of J. R. Jayawardene swept to power in 1977, defeating the United Front government. Jayawardene introduced a new constitution , together with a free-market economy and a powerful executive presidency modelled after that of France. It made Sri Lanka
15544-454: The so-called "Fortress in the Sky", built during the reign of Kashyapa I , who ruled between 477 and 495. The Sigiriya rock fortress is surrounded by an extensive network of ramparts and moats. Inside this protective enclosure were gardens, ponds, pavilions, palaces and other structures. In 993 CE, the invasion of Chola emperor Rajaraja I forced the then Sinhalese ruler Mahinda V to flee to

16214-409: The whole island, colonising it as British Ceylon from 1815 to 1948. A national movement for political independence arose in the early 20th century, and 1948, Ceylon became a dominion . It was succeeded by the republic of Sri Lanka in 1972. Sri Lanka's more recent history was marred by the 26-year Sri Lankan Civil War , which began in 1983 and ended in 2009, when the Sri Lanka Armed Forces defeated
16348-472: The word Tambapanni . The Persians and Arabs referred to it as Sarandīb (the origin of the word " serendipity ") from Sanskrit Siṃhaladvīpaḥ . Ceilão , the name given to Sri Lanka by the Portuguese when they arrived in 1505, was transliterated into English as Ceylon . As a British crown colony , the island was known as Ceylon; it achieved independence as the Dominion of Ceylon in 1948. The country
16482-445: The woven cotton wick, the mantle is a residue of mineral materials (mostly thorium dioxide ), heated to incandescence by the flame from the wick. The thorium and cerium oxide combination produces both a whiter light and a greater fraction of the energy in the form of visible light than a black body at the same temperature would. These types of lamps are still in use today in areas of the world without electricity, because they give
16616-468: Was a massacre that occurred on September 18, 1999, in the small village of Gonagala , located in the Ampara District of Sri Lanka.

16750-415: Was a significant fire risk; in 1880, nearly two of every five New York City fires were caused by defective kerosene lamps. In less-developed countries kerosene is an important source of energy for cooking and lighting. It is used as a cooking fuel in portable stoves for backpackers . As a heating fuel, it is often used in portable stoves, and is sold in some filling stations . It is sometimes used as
16884-603: Was a vassal of Sri Vijaya led by their king Chandrabhanu briefly invaded Sri Lanka from Insular Southeast Asia . They were then expelled by the South Indian Pandyan dynasty. However, this temporary invasion reinforced the steady flow of the presence of various Austronesian merchant ethnic groups, from Sumatrans (Indonesia) to Lucoes (Philippines) into Sri Lanka which occurred since 200 BCE. Chinese admiral Zheng He and his naval expeditionary force landed at Galle, Sri Lanka in 1409 and got into battle with
17018-651: Was destroyed by Bakhtiyar Khalji . It is probable that many of the scriptures from Nalanda are preserved in Sri Lanka's many monasteries and that the written form of the Tripiṭaka , including Sinhalese Buddhist literature, were part of the University of Nalanda.

17286-512: Was first written about in the ninth century by the Persian scholar Rāzi (or Rhazes). In his Kitab al-Asrar ( Book of Secrets ), the physician and chemist Razi described two methods for the production of kerosene, termed naft abyad (نفط ابيض"white naphtha"), using an apparatus called an alembic . One method used clay as an absorbent , and later the other method using chemicals like ammonium chloride ( sal ammoniac ). The distillation process
17420-507: Was held at the Anuradhapura Maha Viharaya in Sri Lanka under the patronage of Valagamba in 25 BCE. The council was held in response to a year in which the harvests in Sri Lanka were particularly poor and many Buddhist monks subsequently died of starvation. Because the Pali Canon was at that time oral literature maintained in several recensions by dhammabhāṇaka s ( dharma reciters), the surviving monks recognised
17554-475: Was registered as a trademark by Nova Scotia geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark . It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft ( jet fuel ), as well as some rocket engines in a highly refined form called RP-1 . It is also commonly used as a cooking and lighting fuel, and for fire toys such as poi . In parts of Asia, kerosene
17688-678: Was repeated until most of the volatile hydrocarbon fractions had been removed and the final product was perfectly clear and safe to burn. Kerosene was also produced during the same period from oil shale and bitumen by heating the rock to extract the oil, which was then distilled. During the Chinese Ming Dynasty , the Chinese made use of kerosene through extracting and purifying petroleum and then converted it into lamp fuel. The Chinese made use of petroleum for lighting lamps and heating homes as early as 1500 BC. Although "coal oil"
17822-400: Was sworn in as Sri Lanka's new president after winning the presidential election as a left-wing candidate. On 14 November 2024, President Anura Kumara Dissanayake's National People's Power (NPP), a left-leaning alliance, received a two-thirds majority in parliament in Sri Lankan parliamentary election. Sri Lanka, an island in South Asia shaped as a teardrop or a pear/ mango , lies on
17956-567: Was well known by industrial chemists at least as early as the 1700s as a byproduct of making coal gas and coal tar, it burned with a smoky flame that prevented its use for indoor illumination. In cities, much indoor illumination was provided by piped-in coal gas , but outside the cities, and for spot lighting within the cities, the lucrative market for fueling indoor lamps was supplied by whale oil , specifically that from sperm whales , which burned brighter and cleaner. Canadian geologist Abraham Pineo Gesner claimed that in 1846, he had given
