British coin Triple Unite

The Triple Unite, valued at sixty shillings, 60/- or three pounds, was the peak British denomination to be produced in the era of the hammered coinage. It was only produced during the Civil War, at King Charles I's mints at Oxford and, on the odd occasion, at Shrewsbury in 1642. It weighed 421 grains, or immediately over seven-eighths of a troy ounce.

The gold coins are unquestionably magnificent pieces of work, and they show the king holding a sword and an olive branch on the obverse, signifying his wish for peace rather than war.

The tremendously rare Shrewsbury-produced coin shows, on the obverse, a plume behind the kings' head surrounded by the legend CAROLUS DG MAG BRIT FRAN ET HIBER REX -- Charles by the grace of God King of Great Britain France and Ireland.

The reverse shows the legend RELIG PROT LEG ANG LIBER PAR in two lines -- The religious conviction of the Protestants, the laws of England and the liberty of Parliament, with three plumes and the value numeral III above the announcement and the year 1642 below it, the whole being surrounded by the legend EXURGAT DEUS DISSIPENTUR INIMICI - Let God arise and His enemies be scattered.

The Oxford issues are extremely similar to the Shrewsbury one, except that the legend on the reverse appears in three lines rather than two, and the obverse legend appears as CAROLUS DG MAG BRIT FR ET HIB REX. Oxford coins come into view with slight design differences in each year of 1642, 1643, and 1644.

Between 1985 and 1997 of Penny coin

Between 1985 and 1997 the cranium by Raphael Maklouf was used, in which the Queen wears the George IV State Diadem. Since 1998 one by Ian Rank-Broadley has been used, again featuring the tiara, with a signature-mark IRB below the portrait. In all cases, the dedication used is ELIZABETH II D.G.REG.F.D. date. Both sides of the coin are bordered by dots.

One penny and two pence coins are officially permitted tender only up to the sum of 20p; these means that it is possible to refuse payment of sums greater than this in one and two pence coins in order to settle a debt.

British One Penny coin

The coin was originally minted from bronze, but since 1992 it has been minted in copper-plated steel. As this is less dense than bronze, post-1992 coins have been to some extent thicker. The British decimal Penny (1p) coin, produced by the Royal Mint, was issued on 15 February 1971, the day the British coinage was decimalised. In practice, it had been existing from banks in bags of £1 for some weeks previously. The coin weighs 3.56 grams and has a diameter of 20.32 millimetres.

The reverse of the coin, planned by Christopher Ironside, is a crowned portcullis with chains (an adaptation of the Badge of Henry VII which is now the Badge of the Palace of Westminster), with the numeral "1" written below the portcullis, and either NEW PENNY (1971–1981) or ONE PENNY (1982–present) above the portcullis.

During the times gone by of the coin, three dissimilar obverses have been used so far. Between 1971 and 1984 the leader of Queen Elizabeth II by Arnold Machin was used, in which the Queen wears the 'Girls of Great Britain and Ireland' Tiara.

The Irish pound coin sketch

The Irish pound coin was introduced on June 20, 1990 using the sketch of a red deer, by the Irish artist Tom Ryan. The 2000 Millennium was used to issue a memorial coin, the design was based on the "Broighter Boat" in the National Museum of Ireland; the coins blueprint was by Alan Ardiff and Garrett Stokes and were issued on November 29, 1999. The coin featured a milled edge - unique in Irish coinage.

The Irish pound coin, which was introduced in 1990, vestiges the largest Irish coin introduced since decimalisation at 3.11 centimetres diameter and was 10 grams weight. The coin was almost impossible to tell apart in dimensions to the old penny coin that circulated before 1971, and was quite similar in diameter to, but thinner, than the half-crown coin.

During the in the early hours circulation of the coin, many payphone and vending machines which had been changed to accept the pound coin also accepted the old penny because of the similar size, the latter coin which was no longer legal tender and had little value to collectors. As a result losses accrued to vending machine operators due to the substitution of the penny coin and additional costs were associated with updating the machines so they would no longer accept the penny

During the early movement of the coin, many payphone and vending machines which had been changed to accept the pound coin also accepted the old penny because of the similar size, the latter coin which was no longer legal gentle and had little value to collectors. As a result losses accrued to vending machine operators due to the substitution of the penny coin and further costs were associated with updating the machines so they would no longer accept the penny.

British coinage

Obverse and reverse of general coins in current circulation, £2, £1, 50p, 20p, 10p, 5p, 2p and 1pThe British currency was decimalised on February 15, 1971. The basic unit of currency – the Pound was unaffected. Before decimalisation there were 240 (old) pennies in a pound, currently there are 100 new pence. The new coins were noticeable with the wording "New Penny" (singular) or "New Pence" (plural) to distinguish them from the old. The word New was dropped following ten years. The symbol p was also adopted to distinguish the new pennies from the old, which used the symbol d.

The earliest pound coin was introduced in 1983 to replace the Bank of England £1 banknote which was discontinued in 1984 (although the Scottish banks continued producing them for some time afterwards. The last of them, the Royal Bank of Scotland £1 note, remained in production until 2003). A circulating bimetallic £2 coin was also introduced in 1998 (first minted in, and dated, 1997) – there had before been commemorative £2 coins which did not normally circulate. The whole amount of coinage in circulation is roughly three and a quarter billion pounds, of which the £1 and £2 coins account for almost two billion pounds.

Axiomatic geometry

A method of computing certain out-of-the-way distances or heights based on similarity of geometric figures and attributed to Thales presaged more conceptual approach to geometry taken by Euclid in his Elements, one of the most influential books ever written. Euclid introduced certain axioms or postulates, expressing primary or self-evident properties of points, lines, and planes. He proceeded to rigorously deduce other properties by mathematical reasoning. The typical feature of Euclid's approach to geometry was its rigour. In the twentieth century, David Hilbert employed obvious reasoning in his attempt to update Euclid and provide modern foundations of geometry.

What is geometry?

Recorded growth of geometry spans more than two millennia. It is hardly astonishing that perceptions of what constituted geometry evolved throughout the ages. The geometric paradigms offered below should be viewed as 'Pictures at an exhibition' of a sort: they do not weaken the subject of geometry but rather reflect some of its defining themes.
Practical geometry:
There is small doubt that geometry originated as a practical science, concerned with surveying, measurements, areas, and volumes. Among the distinguished accomplishments one finds formulas for lengths, areas and volumes, such as Pythagorean theorem, circumference and area of a circle, area of a triangle, volume of a cylinder, sphere, and a pyramid. Development of astronomy led to appearance of trigonometry and spherical trigonometry, together with the attendant computational techniques.

Geometry

Geometryis a part of mathematics disturbed with questions of size, shape, and relative position of figures and with properties of space. Geometry is one of the important oldest sciences. Initially a body of sensible knowledge concerning lengths, areas, and volumes, in the third century B.C. geometry was put into an axiomatic form by Euclid, whose treatment set a standard for many centuries to follow. Astronomy served as an important source of geometric troubles during the next one and a half millennia.

Introduction of coordinates by Descartes and the concurrent improvement of algebra marked a new stage for geometry, since geometric figures, such as plane curves, could now be represented analytically. This played a key role in the appearance of calculus in the seventeenth century. Furthermore, the theory of outlook showed that there is more to geometry than just the metric properties of figures.

Hyperrectangle

In geometry, an orthotope, (also called a hyperrectangle or a box) is the simplification of a rectangle for higher dimensions, formally defined as the Cartesian product of intervals.

A three-dimensional orthotope is also known as right rectangular prism, or cuboid.

An extraordinary case of an n-orthotope is the n-hypercube.

By analogy, the term "hyperrectangle" or "box" refers to Cartesian products of orthogonal intervals of extra kinds, such as ranges of keys in database theory or ranges of integers, rather than real numbers.

Cuboid

In anatomy, the cuboid bone is a bone in the end.
Cuboid

In geometry, a cuboid is a firm figure bounded by six rectangular faces: a rectangular box. All angles are right angles, and opposite faces of a cuboid are identical. It is also a correct rectangular prism. The term "rectangular or oblong prism" is
indefinite. Also the term rectangular parallelepiped is used.

The square cuboid, square box or right square prism (also ambiguously called square prism) is a particular case of the cuboid in which at least two faces are squares. The cube is a special case of the square prism in which every one faces are squares.

If the proportions of a cuboid are a, b and c, then its volume is abc and its surface area is 2ab + 2bc + 2ac.

It is a rounded polyhedron. It contains faces that enclose a single region of space. It has 6 faces, and 8 vertices, and 12 edges.

Euler's formula (the number of faces (F), vertices (V), and edges (E) of a polyhedron are associated by the formula F + V = E + 2 gives here 6 + 8 = 12 + 2.

Cuboid shapes are a lot used for boxes, cupboards, rooms, buildings, etc. Cuboids are among those solids that can tesselate 3-dimensional space. The shape is reasonably versatile in being able to contain several smaller cuboids, e.g. sugar cubes in a box, small boxes in a large box, a cupboard in a room, and rooms in a building.

Rectangle

In geometry, a rectangle is defined as a four-sided figure where all four of its angles are right angles.

From this definition, it follows that a rectangle has two pairs of parallel sides; that is, a rectangle is a quadrilateral. A square is a exceptional kind of rectangle where all four sides have equal length; that is, a square is both a rectangle and a rhombus. A rectangle that is not a square is colloquially known as an four-sided figure.

Normally, of the two opposite pairs of sides in a rectangle, the duration of the longer side is called the length of the rectangle, and the duration of the shorter side is called the width. (Exception: For rectangular steel sheets, the rolling direction is called length, even if it is the shorter side.)

The area of a rectangle is the multiplication of its length and its width; in symbols, A = lw. For example, the area of a rectangle with a length of 6 and a width of 5 would be 30, because 6*5=30

In a rectangle the diagonals cross each others at their respective midpoints, under the same argument as for parallelograms. And unlike general parallelograms the two diagonals of a rectangle have the same length, the length of the diagonal can be found using the Pythagorean theorem.

In calculus, the Riemann fundamental can be thought of as a limit of sums of the areas of arbitrarily thin rectangles.

Sports

Perfect is a physical phenomenon known to athletes? When a person exercise at a certain level for a certain period over a certain number of weeks, their body will raise its metabolism to a higher level - it will continue at this level as long as a certain amount of exercise is performed each couple of days. This result was discovered by Dr. Kenneth H. Cooper for the United States Air Force in the late 1960s. Dr. Cooper coined the term "Training Effect" for this.

The measured effects were that muscles of respiration were strengthened, the heart was strengthened, blood pressure was infrequently lowered and the total amount of blood and number of red blood cells increased, making the blood a more competent carrier of oxygen. VO2 Max was amplified.

The exercise necessary can be talented by any aerobic exercise in a wide diversity of schedules - Dr. Cooper found it best to award "points" for each amount of exercise and require 30 points a week to preserve the Training Effect.

As it would be foolish for someone unconditioned to challenge 30 points in their first week, Dr. Cooper instead recommends a "12-minute test" followed by adherence to the appropriate starting-up schedule in his book. As always, he recommends that a physical exam should lead any exercise program.

Fashionable watches

At the end of the 20th century, Swiss watch makers were seeing their sales go down as analog clocks were considered unfashionable. They joined forces with designers from many countries to reinvent the Swiss watch. The result was that they could considerably decrease the pieces and production time of an analog watch. In fact it was so cheap that if a watch broke it would be cheaper to fling it away and buy a new one than to repair it. One of these Swiss watch manufacturers in progress a new brand, Swatch, and called graphic designers to revamp a new annual collection.

Designer jeans

Designer jeans are high-fashion jeans that are marketed as position symbols. The Nakash brothers (Joe, Ralph, and Avi) are normally credited with starting the trend when they launched their Jordache line of jeans in 1978. Designer jeans are cut for women and men and frequently worn skin-tight. They typically feature prominently able to be seen designer names or logos on the back pockets and on the right front coin-pocket.

Dutch East Indies

The Dutch East Indies, or Netherlands East Indies, (Dutch: Nederlands-Indië; Indonesian: Hindia-Belanda) was created from the nationalized colonies of the former Dutch East India Company that came under administration of the Netherlands throughout the nineteenth century, and now form modern-day Indonesia.

Health care

Health care, or healthcare, is the prevention, treatment, and management of illness and the defense of mental and physical well being through the services available by the medical, nursing, and allied health professions. According to the World Health Organization, health care embrace all the goods and services measured to promote health, as well as preventive, curative and palliative interventions, whether going to be individuals or to populations. The organized provision of such services may make up a health care system. This can include an exact governmental organization such as, in the UK, the National Health Service or cooperation across the National Health Service and Social Services as in Shared Care. Before the term "health care" become popular, English-speakers referred to medicine or to the health sector and spoke of the behavior and prevention of illness and disease.

Vegetable

Vegetable is a cookery term which usually refers to an edible part of a plant. The definition is traditional rather than scientific and is somewhat random and subjective. All parts of herbaceous plants eaten as food by humans, whole or in part, are in general considered vegetables. Mushrooms, though belong to the biological kingdom fungi, and are also commonly considered vegetables. In common, vegetables are consideration of as being savory, and not sweet, although there are many exceptions. Nuts, grains, herbs, spices and culinary fruits are usually not exact vegetables.

Electron

The electron is a basic subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic connections, and its mass is less than one thousandth of that of the smallest atom. Its electric charge is clear by convention to be negative, with a charge of -1 in atomic unit. Together with atomic nuclei, electrons make up atoms; their interaction with adjoining nuclei is the main cause of chemical bonding.
The electron is in the class of subatomic particles called leptons, which are supposed to be basic particles (that is, they cannot be broken down into smaller constituent parts).
As with all particles, electrons are able to act as waves. This is called the wave-particle duality; also known by the term complementarily coined by Niles Bohr and can be established using the double-slit experiment.

Denim

Denim, in American usage since the late eighteenth century, shows a rough cotton twill textile, in which the weft passes under two (twi- "double") or more warp fibers, producing the memorable diagonal ribbing specialized on the reverse of the fabric, which distinguishes denim from cotton duck. Denim was conventionally colored blue with indigo dye to make blue "jeans," though "jean" then denoted a different, lighter cotton textile; the up to date use of jean comes from the French word for Genoa, Italy (Genes), from which the initial denim trousers were made.

Gasoline

Gasoline engines have the benefit over diesel in being lighter and able to work at higher rotating speeds and they are the usual choice for fitting in high presentation sports cars. Continuous development of gasoline engines for over a hundred years has formed improvements in efficiency and reduced pollution. The carburetor was used on nearly all road car engines awaiting the 1980s but it was long realized better control of the fuel/air mixture could be achieved with fuel inoculation.

Indirect fuel injection was initially used in aircraft engines from 1909, in racing car engines from the 1930s, and road cars from the late 1950s. Gasoline Direct Injection (GDI) is now starting to appear in making vehicles such as the 2007 BMW MINI. Wear out gases are also cleaned up by appropriate a catalytic converter into the tire out system. Clean air legislation in many of the car industries most important markets have made both catalysts and fuel injection virtually common fittings. Most modern gasoline engines are also able of running with up to 15% ethanol mixed into the gasoline - older vehicles may have seals and hoses that can be wounded by ethanol. With a small amount of redesign, gasoline-powered vehicles can run on ethanol concentration as high as 85%. 100% ethanol is used in some parts of the world (such as Brazil), but vehicles must be in progress on pure gasoline and switched over to ethanol once the engine is running. Most gasoline engine cars can also run on LPG with the addition up of an LPG tank for fuel storage and carburetion modifications to add an LPG mixer. LPG produces fewer toxic emissions and is a popular fuel for fork lift trucks that have to activate inside buildings.

Early Stages of a pregnant woman and her health

Pregnancy is not an easy job for a woman. Starting from conception to birth, a woman's body carries out the most miraculous process of fertilization, implantation and the maturity and growth of her baby (or babies). Her body is her baby's dwelling place for the next nine months (or around 40 weeks) and the occurrences of pregnancy turn into a journey of many new physical feelings. Whether it is first, second, third (or more) pregnancy, her body will respond in a different way to each individual pregnancy. So health of a pregnant woman is very important to be taken care of.

Throughout the first 12 weeks of pregnancy called the '1st trimester’, a woman's body adjust to present a fostering and protective environment for her baby to grow and develop. Seldom, the early signs of pregnancy can make a woman feel puzzled. This may be for the reason that many of the physical signs of in the early hours of pregnancy such as enlarged tender breasts, sensitivity of tiredness, overstuffed and perhaps experiencing spasms and/or pelvic uneasiness can be considered as normal pre-menstrual signs. In all these stages the health of the woman declines because she is not only feeding herself, also her little developing fetus.

They may also sense disgusted or sick, due to morning sickness. It is not unusual to feel unsure about what is 'normal' during the early stages of pregnancy development, and unfamiliar signs or sensations may trigger concerns about the health, of her and baby. It’s been proved by the Gynecologists that every woman's body will react in a different way to being pregnant. Many women find their early pregnancy symptoms very difficult to cope with, both at work and generally.

Due to continuous vomiting and nourishing the fetus the pregnant woman may be exhausted very easily. She has to constantly keep her energetic by maintaining a healthy diet schedule as prescribed by the physicians. She can have more fresh green vegetables and fruit juices to make her feel fresh and energetic. It’s always significant to make sure that she avoids drinking and smoking because whatever she has will be directly absorbed by the baby. Once the fetus starts developing she has to get primed for all the obstacles she has to experience throughout pregnancy. Many psychologists predict that a healthy pregnancy is not only from taking care of the nutrition for the pregnant women, more than that she has to be taken care from all the hassles in her family. It’s the duty of a loving husband to caress her comfortably and keep her happy always throughout the gestation period. This will not only make the woman feel happy and hopeful it will directly lead to the good development of the fetus.

Compact Disc

A Compact Disc or CD is an optical disc meant to store digital data, initially developed for storing digital audio. The CD, obtainable on the market in late 1982, remains the standard physical medium for commercial audio recordings as of 2007. An audio CD includes one or more stereo tracks stored using 16-bit PCM coding at a sampling rate of 44.1 kHz. Standard CDs include a diameter of 120 mm and can hold about 80 minutes of audio. There are also 80 mm discs, occasionally used for CD singles, which hold around 20 minutes of audio. Compact Disc technology was afterward modified for use as a data storage device, known as a CD-ROM, and it consist of record-once and re-writable media (CD-R and CD-RW respectively). CD-ROMs and CD-Rs stay widely used technologies in the Computer industry as of 2007.

Red blood cell

Red cell is redirecting here, For the US military word, see Red Cell.
Red blood cells are the most ordinary type of blood cell and the vertebrate body's principal means of deliver oxygen from the lungs or gills to body tissues via the blood.

Human red blood cells Red blood cells are also known as RBCs or erythrocytes from Greek erythros for "red" and kytos for "hollow", with cyte nowadays translated as "cell". A schistocyte is a red blood cell undergoes fragmentation, or a fragmented fraction of a red blood cell.

Multiple fruit

A multiple fruit is one fashioned from a cluster of flowers called an inflorescence. Each flower produces a fruit, but these grown-up into a single mass Examples are the pineapple, edible fig, mulberry, osage-orange, and breadfruit.

In the photograph on the right, stages of flowering and fruit development in the noni or Indian mulberry (Morinda citrifolia) can be experiential on a single branch. First an inflorescence of white flowers called a cranium is produced. After fertilization, each flower develops into a drupe, and as the drupes make bigger, they become connate (merge) into a multiple fleshy fruit called a syncarpet.

There are also many dry multiple fruits, e.g.

Tuliptree, multiple of samaras.
Sweet gum, multiple of capsules.
Sycamore and teasel, multiple of achenes.
Magnolia, multiple of follicles.

Water Taxi

A water taxi or river taxi or aquatically disposed taxi is a boat used for public transportation in cities with plentiful water channels. Many cities, including New York City, Boston, Baltimore, Fort Lauderdale, Winnipeg, Vancouver, London, and Tokyo have planned water taxis that operate in a similar manner to ferries or buses. Others, like Venice, have for-hire boats like to traditional taxis. Venice also has a vaporetto or waterbus system that operates in the same way to American "water taxis" (image).

Water taxis also activate in cottage areas where some cottages are available only by water. Visitors can drive to a local marina and take a water taxi to the final purpose.
On March 6, 2004, a "Seaport Taxi," a water taxi service operated by the Living Classrooms Foundation, capsized through a storm near Baltimore's Inner Harbor; 5 passengers died in the accident.

Schooner

A schooner (IPA: [ˈskuːnə]) is a kind of sailing vessel characterized by the use of fore-and-aft sails on two or more masts. Schooners were first used by the Dutch in the 16th or 17th century, and more developed in North America from the time of the American Revolution.

The schooner sail-plan has two or more masts with the forward mast being shorter or the similar height as the rear masts. Most conventionally rigged schooners are gaff rigged, occasionally carrying a squ are top sail on the foremast and occasionally, in addition, a square fore-course (together with the gaff foresail). Schooners that carry square sails are called square-topsail schooners. Modern schooners might be Marconi or Bermuda rigged. Some schooner yachts are Bermudan rig on the mainmast and gaff-rigged on the foremast. A stay-sail schooner has no foresail, but in its place carries and main-stay sail between the masts besides the fore-staysail ahead of the foremast. A stay-sail or gaff-topsail schooner can carry a fisherman (a four sided fore and aft sail) above the main-stay sail or foresail, or a triangular mule. Multi masted stay-sail schooners generally carried a mule above each stay sail apart from the fore-stay sail. Gaff-rigged schooners usually carry a triangular fore-and-aft topsail above the gaff sail on the major topmast and sometimes also on the fore topmast (see illustration), called a gaff-topsail schooner. A gaff-rigged schooner that is not made for carrying one or more gaff topsails is sometimes called a 'bare-headed or bald-headed' schooner. A schooner which has no bowsprit is known as a 'knockabout' schooner.

Motorboat

A motorboat usually speaking is a vessel other than a sailboat or personal watercraft, propelled by an interior combustion engine driving a jet or a propeller. However, the International Regulations for Preventing Collisions at Sea defines that any boat propelled by machinery. A speedboat is a small motorboat intended to move quickly, used in races, for pulling water skiers, as patrol boats, and as fast-moving armed attack vessels by the military. Even inflatable boats with a motor attached which may be serving as a high speed patrol boat or as a plodding walker dingy providing transport to and from a mooring buoy are strictly classified as motorboats.
There are three well-liked variations of power plants: inboard, inboard/outboard, and outboard. If the engine is installed within the boat, it's called a power plant; if it's a detachable module attached to the boat, it's normally known as an outboard motor.

An outboard motor is installed on the rear of a boat and contains the inner combustion engine, the gear decrease (Transmission), and the propeller.An inboard/outboard contains a hybrid of a power plant and an outboard, where the interior combustion engine is contained inboard and the gear reduction and propeller are outside.

A purely inboard boat contains everything apart from a shaft and a propeller inside the vessel. We have two configurations of an inboard, v-drive and straight drive. A direct drive has the power plant mounted close to the middle of the boat with the propeller shaft straight out the back, where a v-drive has the power plant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat than making a 'V' towards the rear.

Yacht

The term luxuriousness yacht refers to a very expensive privately owned yacht which is professionally crewed. Also known as a super-yacht or a mega-yacht, a luxury yacht may be moreover a sailing or motor yacht.
This term began to appear at the beginning of the 20th century when wealthy individuals construct large private yachts for personal pleasure. Examples of early lavishness motor yachts include M/Y (motor yacht) Christina O and M/Y Savarona. Early luxury sailing yachts comprise Americas Cup classic J class racers like S/Y (sailing yacht) Endeavour and Sir Thomas Lipton’s S/Y Shamrock. The New York Yacht Club hosted many early luxury sailing yacht events at Newport, Rhode Island, throughout the Gilded Age.
More recently, over the last decade or two, there has been an increase in the number and fame of large private luxury yachts. Luxury yachts are mainly bountiful in the Mediterranean and Caribbean Seas, although increasingly luxury yachts are cruising in more remote areas of the world. With the increase in demand for luxury yachts there has been an increase custom boat building companies and yacht contract brokers.

Lifeboat

A lifeboat is a rigid or inflatable boat planned to save the lives of people in trouble at sea. The term has somewhat special meanings in British and American usage. The British usage emphasizes particular vessels kept in harbor or near a harbor, often manned by volunteers, considered to quickly reach a ship in trouble. The term "lifeboat" in American usage normally refers to rigid or inflatable vessels accepted by larger ships to allow passengers and crew to escape in an emergency.
The first boat expert as a lifeboat was tested on the River Tyne on January 29, 1790. William would have and Lionel Lufkin both claim to be the inventor of the first lifeboat. One example of an early lifeboat was the Land guard Fort Lifeboat of 1821, considered by Richard Hall Gower.
In U.S. waters, rescue-at-sea is part of the duty of the United States Coast Guard, which employs its multipurpose ships and aircraft in this role. The Coast Guard is also responsible for making sure that the proper type and number of lifeboats (American usage) is available and kept in good repair on any large ship. "Lifeboat drills" are a division of a cruise experience.
