Janez Puhar
Johann Augustin Pucher ( sl, Janez Avguštin Puhar or ''Ivan Pucher''; August 26, 1814 – August 7, 1864) was a Slovene priest, scientist, photographer, artist, and poet who invented an unusual process for making photographs on glass. Although his were not the first glass photographs,Several standard histories of photography widely available during the past sixty years have mentioned the photographs on glass made by John Herschel in September 1839 (e.g., Gernsheim 1986, p. 16), sometimes including an illustration. What is by some definitions the very first successful photograph (i.e., an image produced by the action of light but reasonably light-fast and durable in its final form), a contact-exposed copy of an engraving, was made on glass by the bitumen process of Nicéphore Niépce in 1822 (Gernsheim 1986, p. 9). The later physautotype process, co-invented by Niépce and Louis Daguerre in the early 1830s, was also used to produce photographs on glass, possibly including one m ...

Kranj
Kranj (, german: Krainburg) is the third-largest city in Slovenia, with a population of 37,941 (2020). It is located approximately northwest of Ljubljana. The centre of the City Municipality of Kranj and of the traditional region of Upper Carniola (northwestern Slovenia) is a mainly industrial city with significant electronics and rubber industries. Geography The nucleus of the city is a well-preserved medieval old town, built at the confluence of the Kokra and Sava rivers. The city is served by the Kranj railway station on the route from Ljubljana to Munich, Germany (via Jesenice, Jesenice, Jesenice and Villach, Austria) and a highway. Slovenia's national airport, Ljubljana Jože Pučnik Airport (in Brnik Airport, Brnik) is also very close to Kranj, considerably more so than its nominal client, Ljubljana. In Kranj, the Kokra cuts deeply into the conglomerate, forming a canyon deep. Kosorep, on the northern outskirts of Kranj, is a picturesque site along the river. Parts of the ...

Slovenia
Slovenia ( ; sl, Slovenija ), officially the Republic of Slovenia (Slovene: , abbr.: ''RS''), is a country in Central Europe. It is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the southeast, and the Adriatic Sea to the southwest. Slovenia is mostly mountainous and forested, covers , and has a population of 2.1 million (2,108,708 people). Slovenes constitute over 80% of the country's population. Slovene, a South Slavic language, is the official language. Slovenia has a predominantly temperate continental climate, with the exception of the Slovene Littoral and the Julian Alps. A sub-mediterranean climate reaches to the northern extensions of the Dinaric Alps that traverse the country in a northwest–southeast direction. The Julian Alps in the northwest have an alpine climate. Toward the northeastern Pannonian Basin, a continental climate is more pronounced. Ljubljana, the capital and largest city of Slovenia, is geogr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ljubljana
Ljubljana (also known by other historical names) is the capital and largest city of Slovenia. It is the country's cultural, educational, economic, political and administrative center. During antiquity, a Roman city called Emona stood in the area. Ljubljana itself was first mentioned in the first half of the 12th century. Situated at the middle of a trade route between the northern Adriatic Sea and the Danube region, it was the historical capital of Carniola, one of the Slovene-inhabited parts of the Habsburg monarchy. It was under Habsburg rule from the Middle Ages until the dissolution of the Austro-Hungarian Empire in 1918. After World War II, Ljubljana became the capital of the Socialist Republic of Slovenia, part of the Socialist Federal Republic of Yugoslavia. The city retained this status until Slovenia became independent in 1991 and Ljubljana became the capital of the newly formed state. Name The origin of the name ''Ljubljana'' is unclear. In the Middle Ages, both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abel Niépce De Saint-Victor
Claude Félix Abel Niépce de Saint-Victor (26 July 1805, Saint-Cyr, Saône-et-Loire – 7 April 1870, Paris) was a French photographic inventor. An army lieutenant and cousin of Nicéphore Niépce, he first experimented in 1847 with negatives made with albumen on glass, a method subsequently used by the Langenheim brothers for their lantern slides. At his laboratory near Paris, Niépce de Saint-Victor worked on the fixation of natural photographic colour as well as the perfection of his cousin's heliographic process for photomechanical printing. His method of photomechanical printing, called heliogravure, was published in 1856 in ''Traité pratique de gravure héliographique''. In the 1850s he also published frequently in ''La Lumière''. Near-discovery of radioactivity In 1804 the German chemist Adolph Ferdinand Gehlen (1775-1815) had noticed that when a solution of uranium chloride in ether was exposed to sunlight, it quickly changed color (from bright yellow to green) a ...

Ethanol
Ethanol (abbr. EtOH; also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound. It is an Alcohol (chemistry), alcohol with the chemical formula . Its formula can be also written as or (an ethyl group linked to a hydroxyl group). Ethanol is a Volatility (chemistry), volatile, Combustibility and flammability, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. It is a psychoactive recreational drug, the active ingredient in alcoholic drinks. Ethanol is naturally produced by the fermentation process of Carbohydrate, sugars by yeasts or via Petrochemistry, petrochemical processes such as ethylene hydration. It has medical applications as an antiseptic and disinfectant. It is used as a chemical solvent and in the Chemical synthesis, synthesis of organic compounds, and as a Alcohol fuel, fuel source. Ethanol also can be dehydrated to make ethylene, an important chemical feedstock. As of 2006, world produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bromine
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest element in group 17 of the periodic table (halogens) and is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek (bromos) meaning "stench", referring to its sharp and pungent smell. Elemental bromine is very reactive and thus does not occur as a native element in nature but it occurs in colourless soluble crystalline mineral halide salts, analogous to table salt. In fact, bromine and all the halogens are so reactive that they form bonds in pairs—never in single atoms. While it is rather rare in the Earth's crust, the high solubility of the bromide ion (Br) has caused its accumulation in the oceans. Commercial ...

Mercury (element)
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum ( ) from the Greek words, ''hydor'' (water) and ''argyros'' (silver). A heavy, silvery d-block A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. The term appears to have been first used by Charles Janet. Each block is named after its characteristic orbital: s-blo ... element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in ...

Iodine
Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at , and boils to a violet gas at . The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac, after the Ancient Greek 'violet-coloured'. Iodine occurs in many oxidation states, including iodide (I−), iodate (), and the various periodate anions. It is the least abundant of the stable halogens, being the sixty-first most abundant element. As the heaviest essential mineral nutrient, iodine is required for the synthesis of thyroid hormones. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. The dominant producers of iodine today are Chile and Japan. Due to its high atomic number and ease of attachment to organic compound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bled
Bled (; german: Veldes,''Leksikon občin kraljestev in dežel zastopanih v državnem zboru,'' vol. 6: ''Kranjsko''. 1906. Vienna: C. Kr. Dvorna in Državna Tiskarna, p. 146. in older sources also ''Feldes'') is a town on Lake Bled in the Upper Carniolan region of northwestern Slovenia. It is the administrative seat of the Municipality of Bled. It is most notable as a popular tourist destination in the Upper Carniola region and in Slovenia as whole, attracting visitors from abroad too. Name The town was first attested in written sources as ''Ueldes'' in 1004 (and as ''Veldes'' in 1011). The etymology of the name is unknown and it is believed to be of pre-Slavic origin. The German name of the town, ''Veldes'', was either borrowed from Old Slovene ''*Beldъ'' before AD 800 or is derived from the same pre-Slavic source as the Slovene name.
