Thomas Clark (chemist)
Thomas Clark (1801–1867) was a Scottish chemist. He became known for the discovery of the phosphate of soda, and the process of lime softening of hard water the 'Clark process'. A ''Clark degree (°Clark)'' of water hardness is defined as one grain (64.8 mg) of CaCO3 per Imperial gallon (4.55 litres) of water, equivalent to 14.254 ppm. and 10^5 parts of water Life Clark was born in Ayr, the son of a shipmaster and a needleworker. He went to school at the Ayr Academy, and then was placed in the counting-house of Charles Macintosh in Glasgow. After a few years he moved to the St. Rollox chemical works. In 1836 Clark became lecturer on chemistry at the Glasgow Mechanics' Institution. To improve his standing in the scientific world, he entered as a candidate for the M.D. degree of Glasgow in 1827, completing his curriculum in 1831; in the interval he became apothecary to the infirmary (1829). In 1833 he was elected professor of chemistry in Marischal College, Aberdeen, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marischal College
Marischal College ( ) is a large granite building on Broad Street in the centre of Aberdeen in north-east Scotland, and since 2011 has been the headquarters of Aberdeen City Council. The building was constructed for and is on long-term lease from the University of Aberdeen, which still uses parts of the building to store its museum collections. Today, it provides corporate office space and public access to council services, adjacent to the Town House, the city's historic seat of local government. It is the second largest granite building in the world. The construction of the modern college building began in 1835, following the demolition of previous buildings on the site, and was completed in its present form in the early 1900s. Formerly the seat of the Marischal College and University of Aberdeen founded in 1593, the building was retained by the unified University of Aberdeen, which was created in 1860 by the merger of Marischal College and King's College, Aberdeen, King's Coll ...

Novum Testamentum Graece
(''The New Testament in Greek'') is a critical edition of the New Testament in its original Koine Greek published by ''Deutsche Bibelgesellschaft'' (German Bible Society), forming the basis of most modern Bible translations and biblical criticism. It is also known as the Nestle–Aland edition after its most influential editors, Eberhard Nestle and Kurt Aland. The text, edited by the Institute for New Testament Textual Research, is currently in its 28th edition, abbreviated NA28. The title is sometimes applied to the United Bible Societies (UBS) edition, which contains the same text (its fifth edition referred to as ''UBS5'', contains the text from NA28). The UBS edition is aimed at translators and so focuses on variants that are important for the meaning whereas the NA includes more variants. Methodology The Greek text as presented is what biblical scholars refer to as the " critical text". The critical text is an eclectic text compiled by a committee that compares rea ...

Thomas Graham (chemist)
Thomas Graham (20 December 1805 – 11 September 1869) was a Scottish chemist known for his pioneering work in dialysis and the diffusion of gases. He is regarded as one of the founders of colloid chemistry. Life Graham was born in Glasgow, Scotland and was educated at the High School of Glasgow. Graham's father was a successful textile manufacturer, and wanted his son to enter into the Church of Scotland. Instead, defying his father's wishes, Graham became a student at the University of Glasgow in 1819. There he developed a strong interest in chemistry, studying under Professor Thomas Thomson, who was impressed and influenced by the young man. He left the university after receiving his MA in 1824. He later studied medicine at the University of Edinburgh and then briefly taught chemistry at the Glasgow University Portland Street Medical School. In 1828 he was elected a Fellow of the Royal Society of Edinburgh, his proposer was Edward Turner. He won the Society's Keith Med ...

Calcium Bicarbonate
Calcium bicarbonate, also called calcium hydrogencarbonate, has the chemical formula Ca(HCO3)2. The term does not refer to a known solid compound; it exists only in aqueous solution containing calcium (Ca2+), bicarbonate (), and carbonate () ions, together with dissolved carbon dioxide (CO2). The relative concentrations of these carbon-containing species depend on the pH; bicarbonate predominates within the range 6.36–10.25 in fresh water. All waters in contact with the atmosphere absorb carbon dioxide, and as these waters come into contact with rocks and sediments they acquire metal ions, most commonly calcium and magnesium, so most natural waters that come from streams, lakes, and especially wells, can be regarded as dilute solutions of these bicarbonates. These hard waters tend to form carbonate scale in pipes and boilers, and they react with soaps to form an undesirable scum. Attempts to prepare compounds such as solid calcium bicarbonate by evaporating its solution t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium Pyrophosphate
Tetrasodium pyrophosphate, also called sodium pyrophosphate, tetrasodium phosphate or TSPP, is an inorganic compound with the chemical formula, formula Na4P2O7. As a salt, it is a white, water-soluble solid. It is composed of pyrophosphate anion and sodium ions. Toxicity is approximately twice that of table salt when ingested orally.Handbook of food toxicology', S. S. Deshpande, page 260 Also known is the decahydrate Na4P2O710(H2O). D.L. Perry S.L. Phillips (1995) ''Handbook of inorganic compounds'' CRC Press Use Tetrasodium pyrophosphate is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent, and is often used as a food additive. Common foods containing tetrasodium pyrophosphate include chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives and cat foods and cat treats where it is used as a palatability enhancer.

The first edition of the journal (January 1824) featured an article by James Mill (continued in the second by his son John Stuart Mill), which served as a provocative reprobation of a rival, more well-established journal, the ''Edinburgh Review'', castigating it as an organ of the Whigs (British political party), Whig party, and for sharing the latter's propensity for fence-sitting in the aristocratic interest. The controversy drew in a wide public ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mechanics' Institution
Mechanics' institutes, also known as mechanics' institutions, sometimes simply known as institutes, and also called schools of arts (especially in the Australian colonies), were educational establishments originally formed to provide adult education, particularly in technical subjects, to working men in Victorian-era Britain and its colonies. They were often funded by local industrialists on the grounds that they would ultimately benefit from having more knowledgeable and skilled employees. The mechanics' institutes often included libraries for the adult working class, and were said to provide them with an alternative pastime to gambling and drinking in pubs. Many of the original institutes included lending libraries, and the buildings of some continue to be used as libraries. Others have evolved into parts of universities, adult education facilities, theatres, cinemas, museums, recreational facilities, or community halls. Few are still referred to as mechanics' institutes, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
