Rita Harradence
Rita Harriet Harradence, Lady Cornforth (16 September 1915 − 6 November 2012) was an Australian biochemist who pioneered the synthesis of penicillamine and steroids, and the stereochemistry of molecules involved in the biosynthesis of cholesterol. Biography Rita Harriet Harradence was born in Bexley, New South Wales, on 16 September 1915, the daughter of Walter Charles Harradence and his wife Ethel Harriet Todd. She had brothers, Arthur and Edward. Her father was a carpenter and her mother was a seamstress in a department store. She attended St George Girls High School, an academically selective school for girls, where she excelled, particularly in mathematics. An exceptional teacher, Lilian Whiteoak, sparked an interest in chemistry. When she matriculated in 1933, she was ranked first in New South Wales in chemistry. She also received first class honours in mathematics, and A's in English, French, Latin and mechanics, making her one of the top students in the state. Ha ...

Bexley, New South Wales
Bexley is a suburb in southern Sydney, in the state of New South Wales, Australia. Bexley is located south-west of the Sydney central business district, in the local government area of the Bayside Council and is part of the St George area. History James Chandler named the suburb after his birthplace, Bexley which is in the south-east of London, England. Chandler bought Sylvester’s Farm in 1822, from Thomas Sylvester who had been granted the land about ten years earlier. That year he was also granted of land which stretched from what is now Bexley North to most of Rockdale and Kogarah. The estate was heavily timbered and a track through the centre, used by timber-getters, is today called Forest Road. Queen Victoria Street, Gladstone Street and Beaconsfield Street commemorate the British Queen and two of her prime ministers. Chandler was a well-respected citizen and became known locally as the Squire of Bexley, but his property attracted bushrangers, escaped convicts and other ...

Arthur Birch (organic Chemist)
Arthur John Birch, AC CMG FRS FAA (3 August 1915 – 8 December 1995) was an Australian organic chemist. Birch developed the Birch reduction of aromatic rings (by treatment with lithium metal and ammonia) which is widely used in synthetic organic chemistry. The Birch Reduction enables the modification of steroids. In 1948 Birch published the first total synthesis of a male sex hormone (19-nortestosterone), as the first member of a new structural series. This series later comprised the first oral contraceptive pill, which was made by others. The Birch reduction also allows for the development of other steroid drugs and antibiotics – he also made the first simple synthesis of the ring A-B structure of cholesterol. Birch published over 440 scientific papers and reports. Early life and education Birch won a scholarship to attend the University of Sydney graduating with a BSc in 1937 and a MSc in 1938. He travelled to the University of Oxford to undertake his D.Phil., graduat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Dutch Shell
Shell plc is a British multinational oil and gas company headquartered in London, England. Shell is a public limited company with a primary listing on the London Stock Exchange (LSE) and secondary listings on Euronext Amsterdam and the New York Stock Exchange. It is one of the oil and gas "supermajors" and by revenue and profits is consistently one of the largest companies in the world. Measured by both its own emissions, and the emissions of all the fossil fuels it sells, Shell was the ninth-largest corporate producer of greenhouse gas emissions in the period 1988–2015. Shell was formed in 1907 through the merger of Royal Dutch Petroleum Company of the Netherlands and The "Shell" Transport and Trading Company of the United Kingdom. The combined company rapidly became the leading competitor of the American Standard Oil and by 1920 Shell was the largest producer of oil in the world. Shell first entered the chemicals industry in 1929. Shell was one of the " Seven Sisters" whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blue Mountains (New South Wales)
The Blue Mountains are a mountainous region and a mountain range located in New South Wales, Australia. The region borders on Sydney's metropolitan area, its foothills starting about west of centre of the state capital, close to Penrith on the outskirts of Greater Sydney region. The public's understanding of the extent of the Blue Mountains is varied, as it forms only part of an extensive mountainous area associated with the Great Dividing Range. As defined in 1970, the Blue Mountains region is bounded by the Nepean and Hawkesbury rivers in the east, the Coxs River and Lake Burragorang to the west and south, and the Wolgan and Colo rivers to the north. Geologically, it is situated in the central parts of the Sydney Basin. The ''Blue Mountains Range'' comprises a range of mountains, plateau escarpments extending off the Great Dividing Range about northwest of Wolgan Gap in a generally southeasterly direction for about , terminating at .

Blowpipe (tool)
The term blowpipe refers to one of several tools used to direct streams of gases into any of several working media. Blowpipes for torches If a stream or jet of air is directed through a flame, fuel air mixing is enhanced and the jet exiting the flame is intensely hot. Jewelers and glassblowers engaged in lampwork have used the blowpipe since ancient times, with the blast being powered by the user's lungs. For small work, a mouth-blown blowpipe may be used with a candle flame or an alcohol lamp, with established techniques for applying oxidizing and reducing flames to the workpiece or specimen. Starting in the late 18th Century, blowpipes have been powered by mechanisms, initially bladders and bellows, but now blowers, compressors and compressed gas cylinders are commonplace. While blowing air is effective, blowing oxygen produces higher temperatures, and it is also practical to invert the roles of the gasses and blow fuel through air. Contemporary blowtorches and oxy- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
