The Bochnia Salt Mine (Polish: Kopalnia soli Bochnia) in Bochnia, Poland, is one of the oldest salt mines in the world and is the oldest commercial company in Poland. The Bochnia salt mine was established in 1248 after salt had been discovered there in the 12th and 13th centuries, and became part of the royal mining company, Żupy krakowskie (Kraków Salt Works). In 1990, the mine ceased producing salt but remains a tourist attraction. In 1981 the Bochnia salt mine was declared a heritage monument. It is one of Poland's official national Historic Monuments (Pomnik historii), as designated on 6 October 2000, and is overseen by the National Heritage Board of Poland. The chapel in the mine has train tracks running through it. History The mine shafts measure 4.5 kilometres (2.8 mi) in length at about 330–468 metres (1,083–1,535 ft) in depth below the surface, at 16 levels. In 2013, the mine was added to the UNESCO World Heritage List as an extension of the Wieliczka Salt Mine inscription of 1978. August Passage The August Passage is the...

Furosemide is a loop diuretic medication used to treat fluid build-up due to heart failure, liver scarring, or kidney disease. It had many trade names including Uremide, Lasix, Discoid, and Frusemide. Furosemide may also be used for the treatment of high blood pressure. It can be taken by injection into a vein or by mouth. When given intravenously, furosemide typically begins working within five minutes; when taken by mouth, it typically begins working within an hour.Common side effects include feeling lightheaded while standing, ringing in the ears, and sensitivity to light. Potentially serious side effects include electrolyte abnormalities, low blood pressure, and hearing loss. Blood tests are recommended regularly for those on treatment. Furosemide is a type of loop diuretic that works by decreasing the reabsorption of sodium by the kidneys. Common side effects of furosemide injection include hypokalemia (low potassium level), hypotension (low blood pressure), and dizziness.Furosemide was patented in 1959 and approved for medical use in 1964. It is on the World Health Organization's List of Essential...

In nutrition, biology, and chemistry, fat usually means any ester of fatty acids, or a mixture of such compounds, most commonly those that occur in living beings or in food.The term often refers specifically to triglycerides (triple esters of glycerol), that are the main components of vegetable oils and of fatty tissue in animals; or, even more narrowly, to triglycerides that are solid or semisolid at room temperature, thus excluding oils. The term may also be used more broadly as a synonym of lipid—any substance of biological relevance, composed of carbon, hydrogen, or oxygen, that is insoluble in water but soluble in non-polar solvents. In this sense, besides the triglycerides, the term would include several other types of compounds like mono- and diglycerides, phospholipids (such as lecithin), sterols (such as cholesterol), waxes (such as beeswax), and free fatty acids, which are usually present in human diet in smaller amounts.Fats are one of the three main macronutrient groups in human diet, along with carbohydrates and proteins, and the main components of common food products like milk, butter, tallow, lard, salt pork...

The death of Alexander the Great and subsequent related events have been the subjects of debates. According to a Babylonian astronomical diary, Alexander died in the palace of Nebuchadnezzar II in Babylon between the evening of 10 June and the evening of 11 June 323 BC, at the age of 32. Macedonians and local residents wept at the news of the death, while Achaemenid subjects were forced to shave their heads. The mother of Darius III, Sisygambis, having learned of Alexander's death, became depressed and killed herself later. Historians vary in their assessments of primary sources about Alexander's death, which has resulted in different views about its cause and circumstances. Background In February 323 BC, Alexander ordered his armies to prepare for the march to Babylon. According to Arrian, after crossing the Tigris Alexander was met by Chaldeans, who advised him not to enter the city because their deity Bel had warned them that to do so at that time would be fatal for Alexander. The Chaldeans also warned Alexander against marching westwards as he would then look to the setting sun, a symbol of decline. It was suggested that...
