Robert Warington (agricultural Chemist, Born 1838)
Robert Warington, Jr. (22 August 1838, Spitalfields, London – 20 March 1907, Harpenden) was an English agricultural chemist, known for his research and publications on the chemistry of phosphates and nitrates in agricultural soils. Biography Robert Warington Jr. was the eldest son and second child of the chemist Robert Warington, FRS. After studying chemistry in his father's laboratory and attending lectures by Faraday, Brande, and Hofmann, Robert Warington Jr. became in 1859 an unpaid assistant to Sir John Bennet Lawes at Rothamsted Experimental Station at Harpenden. Warington was from 1862 to 1867 an assistant to the Professor of Chemistry at the Royal Agricultural College at Cirencester. He was from 1876 to 1891 an investigator at Rothamsted Experimental Stations, where he published many articles on soil nitrification. R. Warington here made the first observation that nitrification is a two-step process in 1879. In 1891 Warington was appointed by the committee for the ...

In 1923 she gained her MSc from the University of London with her thesis: The effect of boric acid and borax on the broad bean and certain other plants. In 1928 she studied spectrographic methods of analysis under Professor Lundegårdh at Experimentalfältet, Stockholm. Her work on boron was the basis for her D.Sc. from the Univer ...

Academics Of The University Of Oxford
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agricultural Chemists
Agriculture or farming is the practice of cultivating Plant, plants and livestock. Agriculture was the key development in the rise of Sedentism, sedentary human civilization, whereby farming of Domestication, domesticated species created food Economic surplus, surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into Food, foods, Fiber, fibers, fuels, and raw materials (such as Natural rubber, rubber). Food clas ...

19th-century British Chemists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under Colonialism, colonial rule. It was also marked by the collapse o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

St Nicholas Church, Harpenden
The church of St Nicholas in Harpenden is a parish church in the Church of England. It is a Grade II* listed building. Background It is the oldest known church in Harpenden, Hertfordshire. It was originally built as a Chapel-of-Ease in about 1217, until it was enlarged and the existing tower added in 1470. The old church was demolished in 1861 to make way for a larger building. The tower contains a ring of eight bells, the oldest of which dates from 1612. Harpenden remained part of the ecclesiastical parish of Wheathampstead until 1859 but was, from the Middle Ages, a separate civil parish with its own officials, who were elected annually at the Abbot's Manorial Court, held at Wheathampstead. In 1862, only three years after the long-sought separation from the parish of Wheathampstead, the church was rebuilt to accommodate the growing congregation. The church is part of the Parish of Harpenden St Nicholas, a Church of England Parish within the Diocese of St Albans. Within the ...

Nitrification
''Nitrification'' is the biological oxidation of ammonia to nitrite followed by the oxidation of the nitrite to nitrate occurring through separate organisms or direct ammonia oxidation to nitrate in comammox bacteria. The transformation of ammonia to nitrite is usually the rate limiting step of nitrification. Nitrification is an important step in the nitrogen cycle in soil. Nitrification is an aerobic process performed by small groups of autotrophic bacteria and archaea. Microbiology Ammonia oxidation The oxidation of ammonia into nitrite (also known as nitritation) is performed by two groups of organisms, ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA). AOB AOB can be found among the Betaproteobacteria and Gammaproteobacteria. Since discovery of AOA in 2005, two isolates have been cultivated: ''Nitrosopumilus maritimus'' and ''Nitrososphaera viennensis''. In soils the most studied AOB belong to the genera ''Nitrosomonas'' and '' Nitrococcus''. AOA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
