Drinking Seawater
Salt poisoning is an Substance intoxication, intoxication resulting from the excessive intake of sodium (usually as sodium chloride) either in solid form or in solution (saline water, including brine, brackish water, or seawater). Salt poisoning sufficient to produce severe symptoms is rare, and lethal salt poisoning is possible but even rarer. The lethal dose of table salt is roughly 0.5–1 gram per kilogram of body weight. In medicine, salt poisoning is most frequently encountered in children or infants who may be made to consume excessive amounts of table salt. At least one instance of Murder of Garnett Spears, murder of a hospitalized child by salt poisoning has been reported. Adults can consume too much salt by consuming seawater, pickled goods, brine water or soy sauce. Salt poisoning has been seen in a number of adults with mental health problems. Salt poisoning can affect most species of animals, although it is more common in swine, cattle, and poultry. Symptoms and ph ...

Sea Salt
Sea salt is salt that is produced by the evaporation of seawater. It is used as a seasoning in foods, cooking, cosmetics and for preserving food. It is also called bay salt, solar salt, or simply salt. Like mined rock salt, production of sea salt has been dated to prehistoric times. Composition Commercially available sea salts on the market today vary widely in their chemical composition. Although the principal component is sodium chloride, the remaining portion can range from less than 0.2 to 22% of other salts. These are mostly calcium, potassium, and magnesium salts of chloride and sulfate with substantially lesser amounts of many trace elements found in natural seawater. Though the composition of commercially available salt may vary, the ionic composition of natural saltwater is relatively constant. Historical production Sea salt is mentioned in the Vinaya Pitaka, a Buddhist scripture compiled in the mid-5th century BC. The principle of production is evaporation of the ...

Nerve
A nerve is an enclosed, cable-like bundle of nerve fibers (called axons). Nerves have historically been considered the basic units of the peripheral nervous system. A nerve provides a common pathway for the Electrochemistry, electrochemical nerve impulses called action potentials that are transmitted along each of the axons to peripheral organs or, in the case of sensory nerves, from the periphery back to the central nervous system. Each axon is an extension of an individual neuron, along with other supportive cells such as some Schwann cells that coat the axons in myelin. Each axon is surrounded by a layer of connective tissue called the endoneurium. The axons are bundled together into groups called Nerve fascicle, fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium. The entire nerve is wrapped in a layer of connective tissue called the epineurium. Nerve cells (often called neurons) are further classified as either Sensory neuron, sens ...

Hypernatremia
Hypernatremia, also spelled hypernatraemia, is a high concentration of sodium in the blood. Early symptoms may include a strong feeling of thirst, weakness, nausea, and loss of appetite. Severe symptoms include confusion, muscle twitching, and bleeding in or around the brain. Normal serum sodium levels are 135–145 mmol/L (135–145 mEq/L). Hypernatremia is generally defined as a serum sodium level of more than 145 mmol/L. Severe symptoms typically only occur when levels are above 160 mmol/L. Hypernatremia is typically classified by a person's fluid status into low volume, normal volume, and high volume. Low volume hypernatremia can occur from sweating, vomiting, diarrhea, diuretic medication, or kidney disease. Normal volume hypernatremia can be due to fever, extreme thirst, prolonged increased breath rate, diabetes insipidus, and from lithium among other causes. High volume hypernatremia can be due to hyperaldosteronism, excessive administration of i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Water Aspiration Syndrome
Salt water aspiration syndrome or saltwater aspiration syndrome is a medical condition caused by the inhalation or aspiration (entry of materials into lungs from mouth) of small amounts of salt water during an underwater dive, leading to lung irritation and inflammation. Unlike drowning or near-drowning, it does not involve ingestion of large volumes of water. It often results from faulty diving equipment or improper breathing techniques, allowing fine water droplets to reach the lower respiratory tract. The condition begins with a cough, followed by shortness of breath, chest discomfort or pain, shivering, fever and other systemic symptoms. It can resemble a viral infection but improves within hours, especially with supplemental oxygen. While most cases resolve on their own, severe instances may require critical care. Diagnosis is based on clinical history and symptom progression. Salt water aspiration syndrome was first described in 1970. Cause and mechanism Salt water a ...

The Rime Of The Ancient Mariner
''The Rime of the Ancient Mariner'' (originally ''The Rime of the Ancyent Marinere''), written by English poet Samuel Taylor Coleridge in 1797–98 and published in 1798 in the first edition of '' Lyrical Ballads'', is a poem that recounts the experiences of a sailor who has returned from a long sea voyage. Some modern editions use a revised version printed in 1817 that featured a gloss. The poem tells of the mariner stopping a man who is on his way to a wedding ceremony so that the mariner can share his story. The Wedding-Guest's reaction turns from amusement to impatience to fear to fascination as the mariner's story progresses, as can be seen in the language style; Coleridge uses narrative techniques such as personification and repetition to create a sense of danger, the supernatural, or serenity, depending on the mood in different parts of the poem. The ''Rime'' is Coleridge's longest major poem. It is often considered a signal shift to modern poetry and the beginning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Taylor Coleridge
Samuel Taylor Coleridge ( ; 21 October 177225 July 1834) was an English poet, literary critic, philosopher, and theologian who was a founder of the Romantic Movement in England and a member of the Lake Poets with his friend William Wordsworth. He also shared volumes and collaborated with Charles Lamb, Robert Southey, and Charles Lloyd (poet), Charles Lloyd. He wrote the poems ''The Rime of the Ancient Mariner'' and "Kubla Khan", as well as the major prose work ''Biographia Literaria''. His critical works were highly influential, especially in relation to William Shakespeare, and he helped introduce German idealist philosophy to English-speaking cultures. Coleridge coined many familiar words and phrases, including "suspension of disbelief". He had a major influence on Ralph Waldo Emerson and American transcendentalism. Throughout his adult life, Coleridge had crippling bouts of anxiety and depression; it has been speculated that he had bipolar disorder, which had not been defin ...

History
History is the systematic study of the past, focusing primarily on the Human history, human past. As an academic discipline, it analyses and interprets evidence to construct narratives about what happened and explain why it happened. Some theorists categorize history as a social science, while others see it as part of the humanities or consider it a hybrid discipline. Similar debates surround the purpose of history—for example, whether its main aim is theoretical, to uncover the truth, or practical, to learn lessons from the past. In a more general sense, the term ''history'' refers not to an academic field but to the past itself, times in the past, or to individual texts about the past. Historical research relies on Primary source, primary and secondary sources to reconstruct past events and validate interpretations. Source criticism is used to evaluate these sources, assessing their authenticity, content, and reliability. Historians strive to integrate the perspectives o ...

Jamestown, Virginia
The Jamestown settlement in the Colony of Virginia was the first permanent British colonization of the Americas, English settlement in the Americas. It was located on the northeast bank of the James River, about southwest of present-day Williamsburg, Virginia, Williamsburg. It was established by the London Company as "James Fort" on May 4, 1607 Old Style and New Style dates, O.S. (May 14, 1607 Old Style and New Style dates, N.S.), and considered permanent, after brief abandonment in 1610. It followed failed attempts, including the Roanoke Colony, established in 1585. Despite the dispatch of more supplies, only 60 of the original 214 settlers survived the 1609–1610 Starving Time. In mid-1610, the survivors abandoned Jamestown, though they returned after meeting a resupply convoy in the James River. Jamestown served as the colonial capital from 1616 until 1699. In August 1619, the first recorded slaves from Africa to British North America arrived at present-day Old Point Comfor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Odyssey
The ''Odyssey'' (; ) is one of two major epics of ancient Greek literature attributed to Homer. It is one of the oldest surviving works of literature and remains popular with modern audiences. Like the ''Iliad'', the ''Odyssey'' is divided into 24 books. It follows the heroic king of Ithaca, Odysseus, also known by the Latin variant Ulysses, and his homecoming journey after the ten-year long Trojan War. His journey from Troy to Ithaca lasts an additional ten years, during which time he encounters many perils and all of his crewmates are killed. In Odysseus's long absence, he is presumed dead, leaving his wife Penelope and son Telemachus to contend with a group of unruly suitors competing for Penelope's hand in marriage. The ''Odyssey'' was first written down in Homeric Greek around the 8th or 7th century BC; by the mid-6th century BC, it had become part of the Greek literary canon. In antiquity, Homer's authorship was taken as true, but contemporary schol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelagic
The pelagic zone consists of the water column of the open ocean and can be further divided into regions by depth. The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. In a manner analogous to stratification in the Earth's atmosphere, the water column can be divided vertically into up to five different layers (illustrated in the diagram), with the number of layers depending on the depth of the water. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind st ...

Lifeboat (shipboard)
A lifeboat or liferaft is a small, rigid or inflatable boat carried for emergency evacuation in the event of a disaster aboard a ship. Lifeboat drills are required by law on larger commercial ships. Rafts (raft, liferafts) are also used. In the military, a lifeboat may double as a whaleboat, dinghy, or Captain's gig, gig. The ship's tenders of cruise ships often double as lifeboats. Recreational sailors usually carry inflatable liferafts, though a few prefer small proactive lifeboats that are harder to sink and can be sailed to safety. Inflatable lifeboats may be equipped with auto-inflation (carbon dioxide or nitrogen) canisters or mechanical pumps. A quick release and pressure release mechanism is fitted on ships so that the canister or pump automatically inflates the lifeboat, and the lifeboat breaks free of the sinking vessel. Commercial aircraft are also required to carry auto-inflating liferafts in case of an emergency water landing; offshore oil platforms also have life ...
