Mad Hatter Disease
Erethism, also known as erethismus mercurialis, mad hatter disease, or mad hatter syndrome, is a neurological disorder which affects the whole central nervous system, as well as a symptom complex, derived from mercury poisoning. Erethism is characterized by behavioral changes such as irritability, low self-confidence, depression, apathy, shyness and timidity, and in some extreme cases with prolonged exposure to mercury vapors, by delirium, personality changes and memory loss. People with erethism often have difficulty with social interactions. Associated physical problems may include a decrease in physical strength, headaches, general pain, and tremors, as well as an irregular heartbeat. Mercury is an element that is found worldwide in soil, rocks, and water. People who get erethism are often exposed to mercury through their jobs. Some of the higher risk jobs that can lead to occupational exposure of workers to mercury are working in a chlor-alkali, thermometer, glassblowing ...

Chemical Element
A chemical element is a species of atoms that have a given number of protons in their nuclei, including the pure substance consisting only of that species. Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by any chemical reaction. The number of protons in the nucleus is the defining property of an element, and is referred to as its atomic number (represented by the symbol ''Z'') – all atoms with the same atomic number are atoms of the same element. Almost all of the baryonic matter of the universe is composed of chemical elements (among rare exceptions are neutron stars). When different elements undergo chemical reactions, atoms are rearranged into new compounds held together by chemical bonds. Only a minority of elements, such as silver and gold, are found uncombined as relatively pure native element minerals. Nearly all other naturally occurring elements occur in the Earth as compounds or mixtures. Air is primarily a mixture o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Mining
Silver mining is the extraction of silver from minerals, starting with mining. Because silver is often found in intimate combination with other metals, its extraction requires elaborate technologies. In 2008, ca.25,900 metric tons were consumed worldwide, most of which came from mining. Silver sources Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. Specific minerals include argentite (Ag2 S), chlorargyrite ("horn silver," Ag Cl), polybasite (Ag, Cu)16Sb2S11), and proustite (Ag3AsS3). Silver mainly occurs as a contaminant in chalcopyrite and galena, important ores of copper and lead, respectively.Kassianidou, V. 2003. Early Extraction of Silver from Complex Polymetallic Ores, in Craddock, P.T. and Lang, J (eds) Mining and Metal production through the Ages. London, British Museum Press: 198–206 Some ores are actually mined explicitly for their silver value vs the silver being a byproduct of other metals. However ...

Intention Tremor
Intention tremor is a dyskinetic disorder characterized by a broad, coarse, and low frequency (below 5 Hz) tremor evident during deliberate and visually-guided movement (hence the name intention tremor). An intention tremor is usually perpendicular to the direction of movement. When experiencing an intention tremor, one often overshoots or undershoots one's target, a condition known as dysmetria. Seeberger, Lauren. "Cerebellar Tremor-Definition and Treatment." The Colorado Neurological Institute Review. Fall 2005. Intention tremor is the result of dysfunction of the , particularly on the same side as the tremor in the lateral zone, which controls visually guided movements. Depending on the location of ce ...

Hyperthyroidism
Hyperthyroidism is the condition that occurs due to excessive production of thyroid hormones by the thyroid gland. Thyrotoxicosis is the condition that occurs due to excessive thyroid hormone of any cause and therefore includes hyperthyroidism. Some, however, use the terms interchangeably. Signs and symptoms vary between people and may include irritability, muscle weakness, sleeping problems, a fast heartbeat, heat intolerance, diarrhea, enlargement of the thyroid, hand tremor, and weight loss. Symptoms are typically less severe in the elderly and during pregnancy. An uncommon complication is thyroid storm in which an event such as an infection results in worsening symptoms such as confusion and a high temperature and often results in death. The opposite is hypothyroidism, when the thyroid gland does not make enough thyroid hormone. Graves' disease is the cause of about 50% to 80% of the cases of hyperthyroidism in the United States. Other causes include multinodular goit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theophilus Carter
Theophilus Carter (1824 – 21 December 1904) was an eccentric British furniture dealer who may have been an inspiration for the illustration by Sir John Tenniel of Lewis Carroll's characters the Mad Hatter in his 1865 novel ''Alice's Adventures in Wonderland'' and Hatta in the 1871 sequel ''Through the Looking-Glass''. Inventor and craftsman Carter was born in Oxford, the son of Thomas Carter and Harriet ''née'' Eldridge. Some writers claim that Carter was a servitor at Christ Church, one of the University of Oxford's colleges during the 1850s and 1860s, at the same time that Lewis Carroll was there. However, there is no evidence for this claim (see below). It is claimed by some sources that Carter invented The Alarm Clock Bed, exhibited at the Great Exhibition of 1851, and which tipped out the sleeper at waking-up time into a tub of cold water.''The Sunday Times Magazine'' 24 May 2009 pg 5 However, while an alarm clock bed was indeed displayed at the Exhibition – in ...

Alice In Wonderland
''Alice's Adventures in Wonderland'' (commonly ''Alice in Wonderland'') is an 1865 English novel by Lewis Carroll. It details the story of a young girl named Alice who falls through a rabbit hole into a fantasy world of anthropomorphic creatures. It is seen as an example of the literary nonsense genre. The artist John Tenniel provided 42 wood-engraved illustrations for the book. It received positive reviews upon release and is now one of the best-known works of Victorian literature; its narrative, structure, characters and imagery have had widespread influence on popular culture and literature, especially in the fantasy genre. It is credited as helping end an era of didacticism in children's literature, inaugurating a new era in which writing for children aimed to "delight or entertain". The tale plays with logic, giving the story lasting popularity with adults as well as with children. The titular character Alice shares her given name with Alice Liddell, a girl Carroll knew. ...

Lewis Carroll
Charles Lutwidge Dodgson (; 27 January 1832 – 14 January 1898), better known by his pen name Lewis Carroll, was an English author, poet and mathematician. His most notable works are ''Alice's Adventures in Wonderland'' (1865) and its sequel ''Through the Looking-Glass'' (1871). He was noted for his facility with word play, logic, and fantasy. His poems ''Jabberwocky'' (1871) and ''The Hunting of the Snark'' (1876) are classified in the genre of literary nonsense. Carroll came from a family of high-church Anglicanism, Anglicans, and developed a long relationship with Christ Church, Oxford, where he lived for most of his life as a scholar and teacher. Alice Liddell, the daughter of Christ Church's dean Henry Liddell, is widely identified as the original inspiration for ''Alice in Wonderland'', though Carroll always denied this. An avid puzzler, Carroll created the word ladder puzzle (which he then called "Doublets"), which he published in his weekly column for ''Vanity Fair ( ...

The Mad Hatter
The Hatter is a fictional character in Lewis Carroll's 1865 book ''Alice's Adventures in Wonderland'' and its 1871 sequel ''Through the Looking-Glass''. He is very often referred to as the Mad Hatter, though this term was never used by Carroll. The phrase "mad as a hatter" pre-dates Carroll's works. The Hatter and the March Hare are referred to as "both '' mad''" by the Cheshire Cat, in ''Alice's Adventures in Wonderland'' in the sixth chapter titled "Pig and Pepper". Fictional character biography ''Alice's Adventures in Wonderland'' The Hatter character, alongside all the other fictional beings, first appears in Lewis Carroll's 1865 novel ''Alice's Adventures in Wonderland''.

Fetus
A fetus or foetus (; plural fetuses, feti, foetuses, or foeti) is the unborn offspring that develops from an animal embryo. Following embryonic development the fetal stage of development takes place. In human prenatal development, fetal development begins from the ninth week after fertilization (or eleventh week gestational age) and continues until birth. Prenatal development is a continuum, with no clear defining feature distinguishing an embryo from a fetus. However, a fetus is characterized by the presence of all the major body organs, though they will not yet be fully developed and functional and some not yet situated in their final anatomical location. Etymology The word ''fetus'' (plural ''fetuses'' or '' feti'') is related to the Latin '' fētus'' ("offspring", "bringing forth", "hatching of young") and the Greek "φυτώ" to plant. The word "fetus" was used by Ovid in Metamorphoses, book 1, line 104. The predominant British, Irish, and Commonwealth spelling is '' ...
