Jackfruit Hanging
The jackfruit (''Artocarpus heterophyllus''), also known as jack tree, is a species of tree in the fig, mulberry, and breadfruit family (Moraceae). Its origin is in the region between the Western Ghats of southern India, all of Bangladesh, Sri Lanka, and the rainforests of the Philippines, Indonesia, and Malaysia. The jack tree is well-suited to tropical lowlands, and is widely cultivated throughout tropical regions of the world. It bears the largest fruit of all trees, reaching as much as in weight, in length, and in diameter. A mature jack tree produces some 200 fruits per year, with older trees bearing up to 500 fruits in a year. The jackfruit is a multiple fruit composed of hundreds to thousands of individual flowers, and the fleshy petals of the unripe fruit are eaten. The ripe fruit is sweet (depending on variety) and is more often used for desserts. Canned green jackfruit has a mild taste and meat-like texture that lends itself to being called a "vegetable meat". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Government Of India
The Government of India (ISO: ; often abbreviated as GoI), known as the Union Government or Central Government but often simply as the Centre, is the national government of the Republic of India, a federal democracy located in South Asia, consisting of 28 union states and eight union territories. Under the Constitution, there are three primary branches of government: the legislative, the executive and the judiciary, whose powers are vested in a bicameral Parliament, President, aided by the Council of Ministers, and the Supreme Court respectively. Through judicial evolution, the Parliament has lost its sovereignty as its amendments to the Constitution are subject to judicial intervention. Judicial appointments in India are unique in that the executive or legislature have negligible say. Etymology and history The Government of India Act 1833, passed by the British parliament, is the first such act of law with the epithet "Government of India". Basic structure The gover ...

Polish Academy Of Sciences
The Polish Academy of Sciences ( pl, Polska Akademia Nauk, PAN) is a Polish state-sponsored institution of higher learning. Headquartered in Warsaw, it is responsible for spearheading the development of science across the country by a society of distinguished scholars and a network of research institutes. It was established in 1951, during the early period of the Polish People's Republic following World War II. History The Polish Academy of Sciences is a Polish state-sponsored institution of higher learning, headquartered in Warsaw, that was established by the merger of earlier science societies, including the Polish Academy of Learning (''Polska Akademia Umiejętności'', abbreviated ''PAU''), with its seat in Kraków, and the Warsaw Society of Friends of Learning (Science), which had been founded in the late 18th century. The Polish Academy of Sciences functions as a learned society acting through an elected assembly of leading scholars and research institutions. The Academy h ...

Prussian Academy Of Sciences
The Royal Prussian Academy of Sciences (german: Königlich-Preußische Akademie der Wissenschaften) was an academy established in Berlin, Germany on 11 July 1700, four years after the Prussian Academy of Arts, or "Arts Academy," to which "Berlin Academy" may also refer. In the 18th century, it was a French-language institution since French was the language of science and culture during that era. Origins Prince-elector Frederick III of Brandenburg, Germany founded the Academy under the name of ''Kurfürstlich Brandenburgische Societät der Wissenschaften'' ("Electoral Brandenburg Society of Sciences") upon the advice of Gottfried Wilhelm Leibniz, who was appointed president. Unlike other Academies, the Prussian Academy was not directly funded out of the state treasury. Frederick granted it the monopoly on producing and selling calendars in Brandenburg, a suggestion from Leibniz. As Frederick was crowned "King in Prussia" in 1701, creating the Kingdom of Prussia, the Academy was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baker–Venkataraman Rearrangement
The Baker–Venkataraman rearrangement is the chemical reaction of 2-acetoxyacetophenones with base to form 1,3-diketones. This rearrangement reaction proceeds via enolate formation followed by acyl transfer. It is named after the scientists Wilson Baker and K. Venkataraman. The Baker–Venkataraman rearrangement is often used in the synthesis of chromones and flavones. ''(also in thCollective Volume (1963) 4: 478 (PDF).'' After the base-catalyzed rearrangement, treatment with acid generally affords the chromone or flavone core, though other milder methods have been reported. Mechanism A base abstracts the hydrogen atom alpha to the aromatic ketone, forming an enolate. Then, the enolate attacks the ester carbonyl to form a cyclic alkoxide. The cyclic intermediate is opened up to form a more stable phenolate, which is protonated during acidic work-up to give the desired product. To complete the construction of the chromone or flavone core, cyclodehydration is required. This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
