Margot Dorenfeldt
Margot Dorenfeldt (1895–1986) was the first woman to graduate from Norwegian Institute of Technology (1919) and specialized in inorganic chemistry and electrochemistry. She published several papers in radiochemistry. Biography She was the daughter of Lauritz J. Dorenfeldt (1863–1932), an engineer who was educated in Berlin, and the granddaughter of businessman Lauritz Dorenfeldt Jenssen (1837–1899). Her mother was Aagot Bødtker (1869–1963). Margot was born 2 October 1895 in Worms, Germany, when her family was there; her father was working on assignment as technical director of a cellulose factory. Margot Dorenfeldt was the second woman to enroll at the Norwegian Institute of Technology (NTH) after Aslaug Urbye (who enrolled in 1910, but never completed her studies). In 1919, Dorenfeldt became the first woman to graduate from NTH. While in college, she was active in student debates and made critical comments about her fellow engineers and their record of participation i ...

Worms, Germany
Worms () is a city in Rhineland-Palatinate, Germany, situated on the Upper Rhine about south-southwest of Frankfurt am Main. It had about 82,000 inhabitants . A pre-Roman foundation, Worms is one of the oldest cities in northern Europe. It was the capital of the Kingdom of the Burgundians in the early fifth century, hence is the scene of the medieval legends referring to this period, notably the first part of the ''Nibelungenlied''. Worms has been a Roman Catholic bishopric since at least 614, and was an important palatinate of Charlemagne. Worms Cathedral is one of the imperial cathedrals and among the finest examples of Romanesque architecture in Germany. Worms prospered in the High Middle Ages as an imperial free city. Among more than a hundred imperial diets held at Worms, the Diet of 1521 (commonly known as ''the'' Diet of Worms) ended with the Edict of Worms, in which Martin Luther was declared a heretic. Worms is also one of the historical ShUM-cities as a cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norwegian Institute Of Technology
The Norwegian Institute of Technology (Norwegian: ''Norges tekniske høgskole'', NTH) was a science institute in Trondheim, Norway. It was established in 1910, and existed as an independent technical university for 58 years, after which it was merged into the University of Trondheim as an independent college. In 1996 NTH ceased to exist as an organizational superstructure when the university was restructured and rebranded. The former NTH departments are now basic building blocks of the Norwegian University of Science and Technology (NTNU). NTH was primarily a polytechnic institute, educating master level engineers as well as architects. In 1992 NTH had 7627 master and doctoral students and 1591 employees; it graduated 1262 chartered engineers (master level), 52 chartered architects, and 92 Dr.Ing. (PhD). The operating budget was equivalent to US$100 M, and the total premises amounted to around 260,000 m2 (64 acres). Since the merger, it forms a part of the university campu ...

Radiochemistry
Radiochemistry is the chemistry of radioactive materials, where radioactive isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes (often within radiochemistry the absence of radioactivity leads to a substance being described as being ''inactive'' as the isotopes are ''stable''). Much of radiochemistry deals with the use of radioactivity to study ordinary chemical reactions. This is very different from radiation chemistry where the radiation levels are kept too low to influence the chemistry. Radiochemistry includes the study of both natural and man-made radioisotopes. Main decay modes All radioisotopes are unstable isotopes of elements— that undergo nuclear decay and emit some form of radiation. The radiation emitted can be of several types including alpha, beta, gamma radiation, proton, and neutron emission along with neutrino and antiparticle emission decay pathways. 1. α (alpha) radiation—the emission of an alpha parti ...

Lauritz Dorenfeldt Jenssen
Lauritz Dorenfeldt Jenssen (4 February 1801 – 7 June 1859) was a Norwegian businessperson. He was born in Throndhjem as the son of businessman Matz Jenssen (1760–1813) and his wife Anna, née Schjelderup Dorenfeldt (1763–1846). His older brothers Jens Nicolai and Hans Peter ran the family company ''Jenssen & Co''; Jens Nicolai later founding a rivalling company ''Jenssen & Sønner'' in 1837.''Personalhistorie for Trondhjems by og omegn i et tidsrum af circa 1 1/2 aarhundrede'' by Chr.

Aslaug Urbye
Aslaug ( non, Áslaug ), also called Aslög, Kráka (O.N.: ) or Kraba, is a figure in Norse mythology who appears in Snorri's Edda, the Völsunga saga and in the saga of Ragnar Lodbrok as one of his wives. Aslaug in legend According to the 13th-century ''Tale of Ragnar Lodbrok'', Aslaug was the daughter of Sigurd and the shieldmaiden Brynhildr, but was raised by Brynhildr's foster father Heimer. At the deaths of Sigurd and Brynhildr, Heimer was concerned about Aslaug's security, so he made a harp large enough to hide the girl. He then traveled as a poor harp player carrying the harp containing the girl. They arrived at Spangereid at Lindesnes in Norway, where they stayed for the night in the house of the peasants Áke and Grima. Áke believed the harp contained valuable items and told his wife Grima. Grima then persuaded him to murder Heimer as he was sleeping. However, when they broke the harp open, they discovered a little girl, whom they raised as their own, calling her Kr ...

Chlorine
Chlorine is a chemical element with the Symbol (chemistry), symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity on the revised Electronegativity#Pauling electronegativity, Pauling scale, behind only oxygen and fluorine. Chlorine played an important role in the experiments conducted by medieval Alchemy, alchemists, which commonly involved the heating of chloride Salt (chemistry), salts like ammonium chloride (sal ammoniac) and sodium chloride (common salt), producing various chemical substances containing chlorine such as hydrogen chloride, mercury(II) chloride (corrosive sublimate), and hydrochloric acid (in the form of ).
