James Lind (physician)
James Lind (4 October 1716 – 13 July 1794) was a Scottish doctor. He was a pioneer of naval hygiene in the Royal Navy. By conducting one of the first ever clinical trials, he developed the theory that citrus fruits cured scurvy. Lind argued for the health benefits of better ventilation aboard naval ships, the improved cleanliness of sailors' bodies, clothing and bedding, and below-deck fumigation with sulphur and arsenic. He also proposed that fresh water could be obtained by distilling sea water. His work advanced the practice of preventive medicine and improved nutrition. Early life Lind was born in Edinburgh, Scotland, in 1716 into a family of merchants, then headed by his father, James Lind. He had an elder sister. He was educated at the High School in Edinburgh. In 1731 he began his medical studies as an apprentice of George Langlands, a fellow of the Incorporation of Surgeons which preceded the Royal College of Surgeons of Edinburgh. In 1739, he entered the Navy as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sea Water
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately of sea salt, dissolved salts (predominantly sodium () and chloride () ions). The average density at the surface is 1.025 kg/L. Seawater is density, denser than both fresh water and pure water (density 1.0 kg/L at ) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it Freezing, freezes at about . The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was . Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the diffe ...

George Anson's Voyage Around The World
While Great Britain was fighting the War of Jenkins' Ear with Spain in 1740, Commodore George Anson led a squadron of eight ships on a mission to disrupt or capture the Pacific Ocean possessions of the Spanish Empire. Returning to Britain in 1744 by way of China and thus completing a circumnavigation of the globe, the voyage was notable for the capture of the Manila Galleon, but also for horrific losses from disease with only 188 men of the original 1,854 surviving. An account of the voyage was published in 1748 which being widely read by the general public was a great commercial success and "is still esteemed as the story of a remarkable voyage extremely well told".John Knox Laughton, biography of "Walter, Richard", Dictionary of National Biography, 1885-1900, Volume 5/ref> Background In 1739, the riches that Spain derived from the New World were well known throughout Europe. Huge quantities of silver were shipped from Peru, carried over the isthmus at Panama and then loaded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Anson, 1st Baron Anson
Admiral of the Fleet George Anson, 1st Baron Anson, (23 April 1697 – 6 June 1762) was a Royal Navy officer. Anson served as a junior officer during the War of the Spanish Succession and then saw active service against Spain at the Battle of Cape Passaro during the War of the Quadruple Alliance. He then undertook a circumnavigation of the globe during the War of Jenkins' Ear. Anson commanded the fleet that defeated the French Admiral de la Jonquière at the First Battle of Cape Finisterre during the War of the Austrian Succession. Anson went on to be First Lord of the Admiralty during the Seven Years' War. Among his reforms were the removal of corrupt defence contractors, improved medical care, submitting a revision of the Articles of War to Parliament to tighten discipline throughout the Navy, uniforms for commissioned officers, the transfer of the Marines from Army to Navy authority, and a system for rating ships according to their number of guns.

Connective Tissue
Connective tissue is one of the four primary types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. It develops from the mesenchyme derived from the mesoderm the middle embryonic germ layer. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. The three meninges, membranes that envelop the brain and spinal cord are composed of connective tissue. Most types of connective tissue consists of three main components: elastic and collagen fibers, ground substance, and cells. Blood, and lymph are classed as specialized fluid connective tissues that do not contain fiber. All are immersed in the body water. The cells of connective tissue include fibroblasts, adipocytes, macrophages, mast cells and leucocytes. The term "connective tissue" (in German, ''Bindegewebe'') was introduced in 1830 by Johannes Peter Müller. The tissue was already recognized as a distinct class in the 18th century. ...

Vitamin
A vitamin is an organic molecule (or a set of molecules closely related chemically, i.e. vitamers) that is an Nutrient#Essential nutrients, essential micronutrient that an organism needs in small quantities for the proper functioning of its metabolism. Essential nutrients cannot be biosynthesis, synthesized in the organism, either at all or not in sufficient quantities, and therefore must be obtained through the Diet (nutrition), diet. Vitamin C can be synthesized by some species but not by others; it is not a vitamin in the first instance but is in the second. The term ''vitamin'' does not include the three other groups of essential nutrients: mineral (nutrient), minerals, essential fatty acids, and essential amino acids. Most vitamins are not single molecules, but groups of related molecules called vitamers. For example, there are eight vitamers of vitamin E: four tocopherols and four tocotrienols. Some sources list fourteen vitamins, by including choline, but major health ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitamin C
Vitamin C (also known as ascorbic acid and ascorbate) is a water-soluble vitamin found in citrus and other fruits and vegetables, also sold as a dietary supplement and as a topical 'serum' ingredient to treat melasma (dark pigment spots) and wrinkles on the face. It is used to prevent and treat scurvy. Vitamin C is an essential nutrient involved in the repair of tissue, the formation of collagen, and the enzymatic production of certain neurotransmitters. It is required for the functioning of several enzymes and is important for immune system function. It also functions as an antioxidant. Most animals are able to synthesize their own vitamin C. However, apes (including humans) and monkeys (but not all primates), most bats, some rodents, and certain other animals must acquire it from dietary sources. There is some evidence that regular use of supplements may reduce the duration of the common cold, but it does not appear to prevent infection. It is unclear whether supple ...

Venereal Diseases
Sexually transmitted infections (STIs), also referred to as sexually transmitted diseases (STDs) and the older term venereal diseases, are infections that are Transmission (medicine), spread by Human sexual activity, sexual activity, especially Sexual intercourse, vaginal intercourse, anal sex, and oral sex. STIs often do not initially cause symptoms, which results in a risk of passing the infection on to others. Symptoms and signs of STIs may include vaginal discharge, penile discharge, genital ulcers, ulcers on or around the genitals, and pelvic pain. Some STIs can cause infertility. Bacterial STIs include Chlamydia infection, chlamydia, gonorrhea, and syphilis. Viral STIs include genital herpes, HIV/AIDS, and genital warts. Parasitic STIs include trichomoniasis. STI diagnostic tests are usually easily available in the developed world, but they are often unavailable in the developing world. Some vaccinations may also decrease the risk of certain infections including Hepa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctor Of Medicine
Doctor of Medicine (abbreviated M.D., from the Latin language, Latin ''Medicinae Doctor'') is a medical degree, the meaning of which varies between different jurisdictions. In the United States, and some other countries, the M.D. denotes a professional degree. This generally arose because many in 18th-century medical professions trained in Scotland, which used the M.D. degree nomenclature. In England, however, Bachelor of Medicine, Bachelor of Surgery was used and eventually in the 19th century became the standard in Scotland too. Thus, in the United Kingdom, Republic of Ireland, Ireland and other countries, the M.D. is a research doctorate, honorary degree, honorary doctorate or applied clinical degree restricted to those who already hold a professional degree (Bachelor's/Master's/Doctoral) in medicine. In those countries, the equivalent professional degree to the North American, and some others use of M.D., is still typically titled Bachelor of Medicine, Bachelor of Surgery (M.B ...

Channel Fleet
The Channel Fleet and originally known as the Channel Squadron was the Royal Navy formation of warships that defended the waters of the English Channel from 1854 to 1909 and 1914 to 1915. History Throughout the course of Royal Navy's history there had been different squadrons stationed in home waters. One of the earliest known naval formations to be based at Plymouth was called the Western Squadron which was the forerunner of the Channel Squadron that was later known as the Channel Fleet. In 1650 Captain William Penn, Commander-in-Chief, was charged with guarding the Channel from Beachy Head to Lands End with six ships. This system continued following the Restoration. It was the start of what was to become a Western Squadron. From 1690 the squadron operated out of Plymouth Dockyard during wartime periods, which was for most of the 18th century and early 19th century. In 1854 The Channel Squadron, sometimes known as the Particular Service Squadron, was established. The Channel Squ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.
