Lukács Baths
The Lukács Thermal Bath ( hu, Szt. Lukács gyógyfürdő) is a historic indoor/outdoor thermal bath spa in Budapest, Hungary, heated by natural hot springs. All pools and four saunas can be used by all guests except for the optional area of the sauna world, which contains five more saunas, ice cooling pool, igloo and heated roman bench. There are also sauna nights on Fridays from 20:00 to 02:00. History Thermal baths have been used at this location since at least the 12th century (by the Knights Hospitallers), and as part of the interior there is a wall that is a remainder of a former Ottoman powder mill (the Császár mill) which used the hot spring water as a source of power. The first spa hotel was completed in the 1880s, and named for Saint Luke. This spa was expanded with a drinking-water hall constructed in 1937, and in 1979 a health clinic was added. The Császár Thermal Bath is the oldest continually operating thermal bath in Budapest, and was originally built by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Baths In Budapest
A thermal column (or thermal) is a rising mass of buoyant air, a convective current in the atmosphere, that transfers heat energy vertically. Thermals are created by the uneven heating of Earth's surface from solar radiation, and are an example of convection, specifically atmospheric convection. Thermals on Earth The Sun warms the ground, which in turn warms the air directly above. The warm air near the surface expands, becoming less dense than the surrounding air. The lighter air rises and cools due to its expansion in the lower pressure at higher altitudes. It stops rising when it has cooled to the same temperature, thus density, as the surrounding air. Associated with a thermal is a downward flow surrounding the thermal column. The downward-moving exterior is caused by colder air being displaced at the top of the thermal. The size and strength of thermals are influenced by the properties of the lower atmosphere (the ''troposphere''). When the air is cold, bubbles of warm ...

Fluoride Ion
Fluoride (). According to this source, is a possible pronunciation in British English. is an inorganic, monatomic anion of fluorine, with the chemical formula (also written ), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and minerals are important chemical reagents and industrial chemicals, mainly used in the production of hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Fluoride is the simplest fluorine anion. In terms of charge and size, the fluoride ion resembles the hydroxide ion. Fluoride ions occur on Earth in several minerals, particularly fluorite, but are present only in trace quantities in bodies of water in nature. Nomenclature Fluorides include compounds that contain ionic fluoride and those in which fluoride does not dissociate. The nomenc ...

Sodium
Sodium is a chemical element with the symbol Na (from Latin ''natrium'') and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not occur in nature, and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide (lye) is used in soap manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals including h ...

Chloride
The chloride ion is the anion (negatively charged ion) Cl−. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water.Green, John, and Sadru Damji. "Chapter 3." ''Chemistry''. Camberwell, Vic.: IBID, 2001. Print. It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating liquid flow in and out of cells. Less frequently, the word ''chloride'' may also form part of the "common" name of chemical compounds in which one or more chlorine atoms are covalently bonded. For example, methyl chloride, with the standard name chloromethane (see IUPAC books) is an organic compound with a covalent C−Cl bond in which the chlorine is not an anion.

Magnesium Sulfate
Magnesium sulfate or magnesium sulphate (in English-speaking countries other than the US) is a chemical compound, a salt with the formula , consisting of magnesium cations (20.19% by mass) and sulfate anions . It is a white crystalline solid, soluble in water but not in ethanol. Magnesium sulfate is usually encountered in the form of a hydrate , for various values of ''n'' between 1 and 11. The most common is the heptahydrate , known as Epsom salt, which is a household chemical with many traditional uses, including bath salts. The main use of magnesium sulfate is in agriculture, to correct soils deficient in magnesium (an essential plant nutrient because of the role of magnesium in chlorophyll and photosynthesis). The monohydrate is favored for this use; by the mid 1970s, its production was 2.3 million tons per year. The anhydrous form and several hydrates occur in nature as minerals, and the salt is a significant component of the water from some springs. Hydrates Magnesi ...

Magnesium Bicarbonate
Magnesium bicarbonate or magnesium hydrogencarbonate, Mg( H CO3)2, is the bicarbonate salt of magnesium. It can be formed through the reaction of dilute solutions of carbonic acid (such as seltzer water) and magnesium hydroxide (milk of magnesia). It can be prepared through the synthesis of magnesium acetate and sodium bicarbonate: :: Magnesium bicarbonate exists only in aqueous solution. Magnesium does not form solid bicarbonate as does lithium. To produce it, a suspension of magnesium hydroxide is treated with pressurized carbon dioxide, producing a solution of magnesium bicarbonate: ::Mg(OH)2 + 2 CO2 → Mg(HCO3)2 Drying the resulting solution causes the magnesium bicarbonate to decompose Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is ..., yielding magnesium carbonate, ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Calcium Hyrodgencarbonate
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 to dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saint Luke
Luke the Evangelist (Latin: '' Lucas''; grc, Λουκᾶς, '' Loukâs''; he, לוקאס, ''Lūqās''; arc, /ܠܘܩܐ לוקא, ''Lūqā’; Ge'ez: ሉቃስ'') is one of the Four Evangelists—the four traditionally ascribed authors of the canonical gospels. The Early Church Fathers ascribed to him authorship of both the Gospel of Luke and the Acts of the Apostles. Prominent figures in early Christianity such as Jerome and Eusebius later reaffirmed his authorship, although a lack of conclusive evidence as to the identity of the author of the works has led to discussion in scholarly circles, both secular and religious. The New Testament mentions Luke briefly a few times, and the Epistle to the Colossians refers to him as a physician (from Greek for 'one who heals'); thus he is thought to have been both a physician and a disciple of Paul. Since the early years of the faith, Christians have regarded him as a saint. He is believed to have been a martyr, reportedly having bee ...
