Von Ahnska magasinet is a port warehouse, which is located on Storgatan in Umeå, Sweden.
 The warehouse was originally a wooden barn built by Lieutenant Colonel Ludwig August von Hedenberg in 1887.
 The building survived the great fire of 1888.
 During the same year, the merchant Johan Viktor von Ahn bought the building which he extended towards the Ume River.
The culture of Denmark has a rich intellectual and artistic heritage.
 The astronomical discoveries of Tycho Brahe (1546–1601), Ludwig A. Colding's (1815–1888) neglected articulation of the principle of conservation of energy, and the foundational contributions to atomic physics of Niels Bohr (1885–1962); in this century Lene Vestergaard Hau (born 1959) in quantum physics involving the stopping of light, advances in nano-technology, and contributions to the understanding of Bose-Einstein Condensates, demonstrate the range and endurance of Danish scientific achievement.
 The fairy tales of Hans Christian Andersen (1805–1875), the philosophical essays of Søren Kierkegaard (1813–1855), the short stories of Karen Blixen, penname Isak Dinesen, (1885–1962), the plays of Ludvig Holberg (1684–1754), modern authors such as Herman Bang and Nobel laureate Henrik Pontoppidan and the dense, aphoristic poetry of Piet Hein (1905–1996), have earned international recognition, as have the symphonies of Carl Nielsen (1865–1931).
 From the mid-1990s, Danish films have attracted international attention, especially those associated with Dogme 95 like those of Lars Von Trier.
 Denmark has had a strong tradition of movie making and Carl Theodor Dreyer has been recognised as one of the world's greatest film directors.
James Prescott Joule FRS HFRSE DCL LLD ( ; (24 December 1818 11 October 1889) was an English physicist, mathematician and brewer, born in Salford, Lancashire.
 Joule studied the nature of heat, and discovered its relationship to mechanical work (see energy).
 This led to the law of conservation of energy, which led to the development of the first law of thermodynamics.
Mayer's reagent is an alkaloidal precipitating reagent used for the detection of alkaloids in natural products.
 Mayer’s reagent is freshly prepared by dissolving a mixture of mercuric chloride (1.36 g) and of potassium iodide (5.00 g) in water (100.0 ml).
 Most alkaloids are precipitated from neutral or slightly acidic solution by Mayer’s reagent (potassiomercuric iodide solution) to give a cream coloured precipitate.
 This test was invented by the German Chemist, Julius Robert Von Mayer (1814–1878).
Ludwig August Colding (13 July 1815 – 21 March 1888) was a Danish civil engineer and physicist who articulated the principle of conservation of energy contemporaneously with, and independently of, James Prescott Joule and Julius Robert von Mayer though his contribution was largely overlooked and neglected.
Friedrich Robert von Beringe (21 September 1865 - 5 July 1940) was a German army officer, born in Aschersleben.
 He was the son of Mathilde Luise and Captain Karl Robert von Beringe of the Prussian Cavalry.
The Asymmetry Principle was developed by economist Peter Tertzakian, and was first presented in his book "The End of Energy Obesity" published in 2009.
 Historically, each energy crisis has brought society to a solutions crossroad: find more or use less.
 The latter path through conservation efforts has seldom triggered any excitement, so energy shocks have always triggered calls for more supply.
 With six billion people from the developing world seeking the same living standards as those in the affluent OECD countries the earth’s resources and environment are being put under great strain again.
 Tertzakian terms this problem the modern world's "energy obesity."
 In pursuit of a solution, the Asymmetry Principle calls for a shift in focus from energy supply to end use consumption.
 Within energy economics, Tertzakian highlights how to lower energy consumption without jeopardizing GDP and quality of life.
Karl Ludwig August Friedrich Maximilian Alfred, Freiherr von Prel, or, in French, Carl Ludwig August Friedrich Maximilian Alfred, Baron du Prel (3 April 1839 – 4 August 1899), was a German philosopher and writer on mysticism and the occult.
 In the literature it has become customary to refer to him under various abbreviated French forms of his name, usually "Carl Du Prel," "Baron Carl Du Prel," or simply "Baron Du Prel."
Julius Robert Mayer (November 25, 1814 – March 20, 1878) was a German physician, chemist and physicist and one of the founders of thermodynamics.
 He is best known for enunciating in 1841 one of the original statements of the conservation of energy or what is now known as one of the first versions of the first law of thermodynamics, namely that "energy can be neither created nor destroyed".
 In 1842, Mayer described the vital chemical process now referred to as oxidation as the primary source of energy for any living creature.
 His achievements were overlooked and priority for the discovery of the "mechanical equivalent of heat" was attributed to James Joule in the following year.
 He also proposed that plants convert light into chemical energy.
Robert von Mohl (17 August 1799 – 4 November 1875) was a German jurist.
 Father of diplomat Ottmar von Mohl.
 Brother of Hugo von Mohl, Moritz Mohl and Julius von Mohl.
