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.

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.

How computers work

A general purpose computer has four main areas: the arithmetic and logic unit (ALU), the control unit, the memory, and the lost one input and output devices (collectively termed I/O). These parts are interconnected by busses,over and over again made of groups of wires.

The control unit, ALU, registers, and basic I/O (and often other hardware closely linked with these) are as a group known as a central processing unit (CPU). Early CPUs were composed a lot of separate components but since the mid-1970s CPUs have typically been constructed on a single integrated circuit called a microprocessor.

Programs in computer

In practical terms, a computer program might include anywhere from a dozen instructions to a lot of millions of instructions for something like a word processor or a web browser. A typical modern computer can carry out billions of instructions every second and nearly never make a mistake over years of operation.

Large computer programs may take groups of computer programmers years to write and the probability of the entire program having been written completely in the manner intended is unlikely. Errors in a computer programs are called bugs. Sometimes bugs are benign and it not affect the usefulness of the program, in some other cases they might cause the program to completely fail (crash), in yet other cases there may be subtle problems. Bugs are generally not the fault of the computer. Since computers merely execute the lot of instructions they are given, bugs are nearly always the result of programmer error or an oversight made in the program's design.

Stored program architecture

The defining feature of latest computers which distinguishes them from all other machines is that they can be programmed. That is to say that a set of instructions (the program) can be given to the computer and it will store them and carry them out at some time in the future.

In most cases, computer instructions are simple: add one number to another, move some data from one place to another, send a message to some external device, etc. These instructions are read from the computer's memory and are useually carried out (executed) in the order they were given. However, there are geneally specialized instructions to tell the computer to jump ahead or backwards to some other place in the program and to carry on executing from there. These are called as "jump" instructions (or branches).

First Programmable machine computer

In 1837, Charles Babbage was the initialyt to conceptualize and design a fully programmable mechanical computer that he called "The Analytical Engine". Due to small finance, and an inability to resist tinkering with the design, Babbage never actually built his Analytical Engine.

Large-scale automated data processing of punched cards was performed for the U.S. Census in 1890 by tabulate machines designed by Herman Hollerith and created by the Computing Tabulating Recording Corporation, which later became IBM. By the end of the 19th century a number of technologies that would later prove useful in the realization of user computers had begun to appear: the punched card, Boolean algebra, the vacuum tube (thermionic valve) and the teleprinter.

During the first half of the 20th century, many scientific computing needs were met by increasingly sophisticated analog computers, which used a direct mechanical or electrical representation of the problem as a basis for computation. However, these were not programmable and usually lacked the versatility and accuracy of modern digital computers.

History of computing

It is difficult to identify any one device as the earliest computer, partly because the term "computer" has been subject to changeable interpretations over time.

Originally, the term "computer" referred to a person who performed numerical calculations (a human computer), often with the aid of a mechanical calculating device. Examples of early perfunctory computing devices included the abacus, the slide rule and arguably the astrolabe and the Antikythera mechanism (which dates from about 150-100 BC). The end of the center Ages saw a re-invigoration of European mathematics and engineering, and Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers.

Computer

A computer is a machine which manipulates data according to a list of instructions which makes it an best example of a data processing system.

Computers take many part of physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred present personal computers. Modern computers are based on comparatively tiny integrated circuits and are millions to billions of times more capable while occupying a little of the space. Today, simple computers may be made small sufficient to fit into a wrist watch and be powered from a watch battery. Personal computers in different forms are icons of the information age and are computer in use today is by remote the embedded computer. Embedded computers are small, simple devices that are often used to manage other devices — for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.

Stamp hinge

Stamp hinges are tiny, folded, rectangular pieces of paper covered with a mild gum, used to hold postage stamps onto the pages of a stamp album. The short end is moistened and affixed to the stamp; the long end is similarly affixed to the page. The hinge keeps the stamp on the page while still allows it to be lifted to look at the back.

The best stamp hinges are also designed to be "peel able", meaning that the stamp may be detached from the page, and the hinge from the stamp, without any damage to either. Not all makes of hinge have this property, and the backs of many stamps have "hinge remnants", where the hinge has torn gone rather than hire go of the stamp. This is especially common for mint stamps, where the stamps own gum adheres tightly to the hinge. Some old stamps may essentially have multiple hinge remnants layered on top of each other. Conversely, careless removal of a hinge may get away a layer of the stamp's paper, ensuing in a type of stamp thin known as a "hinge thin".

Even with the use of peel able hinges and care taken to minimize the moisture used, the hinge will leave a visible commotion in the gum of an unused stamp. While this was previously a matter of indifference, since about the middle of the 20th century many collectors have come to prefer "unhinged stamps" showing no trace of hinging.

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.

Ring

A finger ring is a band worn as kind of ornamental jeweler around a finger; it is the most ordinary current meaning of the word ring. Additional types of metal bands worn as ornaments are also called rings, such as arm rings and neck rings.

Rings are worn by both men and women and can be of any superiority. Rings can be made of metal, plastic, wood, bone, glass, gemstone and other equipment. They may be set with a "stone" of some sort, which is often a valuable or semi-precious gemstone such as ruby, sapphire or emerald, but can also be of almost any material.

There are a variety of methods for determining proper ring size. Quantities of the largest rings in the world are made for the winning team of the Super Bowl. The unofficial record for the largest championship ring ever obtainable to a professional sports team belongs to the 2003 World Series champions Florida Marlins, with a weight of over 110 grams and with over 240 stones.

Rings can be worn on any finger, still on toe fingers. In Western society, the traditional "ring finger" for the wearing of an engagement or wedding ring is the fourth finger of the left hand with the thumb counting as finger number one. The signet ring, a ring designate nobility, is normally worn on the little (fifth) finger of the right or left hand, depending on nationality.

Economic and social history


Dutch economic strategy for the colony throughout the eighteenth and nineteenth centuries can be clear along three overlapping periods: the Cultivation System, the Liberal Period, and the Ethical Period. Throughout these periods, and until Indonesian independence, the utilization of Indonesia's wealth contributes to the industrialization of the Netherlands. Large expanses of Java, for example, became plantations cultivated by Javanese peasants, together by Chinese intermediaries, and sold on overseas markets by European merchants. Before World War II, the majority of the world's supply of quinine and pepper, over a third of its rubber, a quarter of its coconut products and a fifth of is tea, sugar, coffee, and oil. Indonesia complete the Netherlands was one of the world's most important colonial powers.

Despite increasing returns from the Dutch system of land tax, Dutch finances had been severely exaggerated by the cost of the Java and Padre Wars. The Dutch loss of Belgium in 1830 brought the Netherlands to the brink of bankruptcy, and a concerted Dutch utilization of Indonesian resources commenced. In 1830, a new governor general, Johannes van den Bosch, was selected to make the Dutch East Indies to pay their way. An agricultural plan of government-controlled forced cultivation was introduced to Java. Known as the Cultivation System (Dutch: cultuurstelsel); much of Java became a Dutch plantation, making it a profitable, self-sufficient colony and saving the Netherlands from bankruptcy. The Cultivation System, however, brought much economic hardship to Javanese peasants, who suffer famine and epidemics in the 1840s.

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.

Carrot

The carrot (Daucus carota subsp. sativus) is a root vegetable, usually orange or white, or pink in color, with a crunchy texture when fresh. The suitable for eating part of a carrot is a taproot. It is a cultivated form of the wild carrot Daucus carota, national to Europe and southwestern Asia. It has been bred for its very much inflamed and more palatable, less woody-textured edible taproot, but is still the similar species.

It is a biennial plant which grows a rosette of leaves in the spring and summer, while building up the fat taproot, which stores big amounts of sugars for the plant to flower in the second year. The peak stem grows to about 1 m tall, with an umbel of white flowers.

Carrots can be eaten raw, whole, chopped, grate, or added to salads for color or texture. They are also often chopped and boiled, fried or steamed, and cooked in soups and stews, as well as fine baby foods and choose pet foods. A well recognized dish is carrots julienne. Grated carrots are used in carrot cakes, as healthy as carrot puddings, an old English dish thought to have originated in the early 1800s.

Harrington jacket

A Harrington jacket is a type of tiny, lightweight jacket, made of cotton, polyester, wool or suede — generally with a tartan or check-patterned lining.

The initial Harrington-style jackets were made by British clothing company, Baracuta, in the 1930s; the company is still making the same model, the G9. This style of jacket got the nickname Harrington because it was worn by the personality Rodney Harrington (played by Ryan O'Neal) in the 1960s television program Peyton Place; John Simmons, who opened 'The Ivy Shop', Richmond, London, claims to have coined this explanation.

Diesel

Diesel engine cars have long been admired in Europe with the first models being introduced in the 1930s by Mercedes Benz and Citroen. The major benefit of Diesels is a 50% fuel burn competence compared with 27% in the best gasoline engines. A down side of the diesel is the presence in the wear out gases of fine soot particulates and manufacturers are now preliminary to fit filters to remove these. Many diesel motorized cars can also run with little or no modifications on 100% biodiesel.

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.

DVD

DVD ("Digital Versatile Disc" or "Digital Video Disc") is an admired optical disc storage space media format that can be used for data storage, like movies with high video and sound quality. DVDs be similar to Compact Discs in that they have the precise appearance (i.e. diameter: 120 mm or 4.72 in, occasionally 80 mm or 3.15 in.) and both are optical storage media so similar that a DVD reader or writer can usually read CDs, but DVDs are encoded in a dissimilar format of much greater density, allowing a data storage capability 8 times greater (single-layer, single-sided).

All read-only DVD discs, regardless of type, are DVD-ROM discs. This includes replicated (factory pressed), recorded (burned), video, audio, and data DVDs. A DVD with properly formatted and structured video content is a DVD-Video disc. Everything else, (including other types of DVD discs with video content) is known as a DVD-Data disc. Consumers use the term "DVD-ROM" to refer to pressed data discs only, but that is wrong usage; moreover, the term DVD is also applied basically in describing newer video disc formats, Blu-ray Disc and HD DVD.

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.

Sailboat

The term sailboat has a wide meaning generally including yachts, (large sailboats) and smaller vessels of many configurations, which use wind as the chief means of propulsion. Some of the variations other than size are: hull configuration (monohull, catamaran, trimaran), keel type (full, fin, wing, centerboard etc.), purpose (sport, racing, cruising), number and arrangement of masts, and the sail chart. Some of the terms underneath have had various meanings through history, but now have a specific meaning in the parlance of modern yachting. See also the articles on sailing ships and yachts; each of these terms generally describes a larger vessel than a sailboat; however, the distinctions are fuzzy and the definitions differ by region and culture. At the smaller end, the distinction in the midst of, sailboards, windsurfing, and dinghies can be vague.

Sunday, June 10, 2007

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.

Kayak

A kayak is a little human-powered boat. It classically has a covered deck, and a cockpit covered by a spray deck. It is propelled by a double-bladed paddle by sitting paddlers. The kayak was used by the inhabitant Ainu, Aleut and Eskimo hunters in sub-arctic regions of northeastern Asia, North America and Greenland. Modern kayaks come in a wide diversity of designs and materials for particular purposes. Kayaks are frequently referred to as canoes in Great Britain and Ireland.
Traditional kayaks typically accommodate one, two or infrequently three paddlers who sit facing ahead in one or more cockpits below the deck of the boat. If used the spray deck or comparable waterproof garment attach securely to the edges of the cockpit, prevent the entry of water from waves or spray, and making it possible in some styles of boat, to roll the kayak upright again without it filling with water or eject the paddler.
Kayaks differ definitely in design and history from canoes, which are more flat-bottomed boats propel by single-bladed paddles by a kneeling paddler, even though some modern canoes may be difficult for a non-expert to distinguish from a kayak. One benefit to a kayak is that with a canoe's high bow, it is harder to paddle against the wind. As Kayaks do not have such high sides, it is easier to paddle on a breezy day.

Hovercraft

A hovercraft, or air-cushion vehicle (ACV), is a vehicle or craft that can be hold up by a cushion of air dispossessed downwards against a surface close below it, and can in principle travel over any relatively smooth surface, such as gently sloping land, water, or marshland, while having no substantial contact with it.
Hovercraft has one or more parts of engines (some craft, such as the SR-N6, have one engine with a drive split through a gearbox). One engine drives the fan (the impeller) which is in charge for exciting the vehicle by forcing air under the craft. The air therefore must exit throughout the "skirt", lifting the craft above the area which the craft resides. One or more additional engines are used to offer thrust in order to propel the craft in the favorite direction. Some hovercraft utilized ducting to allow one engine to perform both tasks by directing some of the air to the skirt, the rest of the air passing out of the back to push the craft forward.

Folding boat

A Folding boat is frequently a smaller boat, typically ranging between 8 to 12 feet. This style of boat must also allow for easy lifting which require a glow weight. Folding boats are made from light weight resources such as marine plywood, aluminum or more exotic man-made materials lighter and tougher than aluminum. Folding boats fill a need for people who do not have storage gap for a full-size boat or cannot transport a full-size boat.
There are more than a few folding boat makers and folding kayak makers in the world from the USA, England and Australia with several variations and models. The handyman can also produce their own unit at home with plans or buy designing their own version.
Although there is much to be thought by the advantages of a folding boat, they are not common place in boating and aluminum and inflatable alternatives are far more common despite some folding boats having been sold for several decades.

Bicycle

A hybrid vehicle (HV) is a vehicle that uses two different power sources such as:
* An on-board rechargeable energy storage system (RESS) and a fueled power source for means of transportation force
* Human powered bicycle with sequence assist
* A sail boat with electric control
The term the commonly refers to petroleum electric hybrid vehicle, also called Hybrid-electric vehicle (HEV) which use internal burning engines and electric batteries to power electric motors.
The term hybrid when used in relative with cars also has other uses. Prior to its modern meaning of hybrid force, the word hybrid was used in the United States to mean a vehicle of mixed countrywide origin; generally, a European car fitted with American mechanical components. This significance has fallen out of use. In the import scene, hybrid was often used to describe an engine swap. Some have also referred to flexible-fuel vehicles as hybrids because they can use a combination of different fuels — naturally gasoline and ethanol alcohol fuel.

A Civil Role Model
The word civil carries a lot of power. The usage needs to be carefully considered when it's entered into a sentence or an expression. Civil means a wide difference of things. It can be defined as a way to be attentive of the forms required for good reproduction. It can also be a means to the needs and affairs of the common public. However, the latter of the two definitions can also be extended to include a definition of the private rights and the remedy sought by action or costume. The point is that the word civil has a greater significance that has been embraced by our American legal traditions. It is the premise that law is there to provide the people and the lawyers are nothing more than mere guardians of law.
These are thoughts that were measured during the class viewing of A Civil Action. In the events of the case, there were many concerns that were brought up about our permissible culture.

Carts

Carts have been mention in journalism as far back as the second millennium B.C. The Indian sacred book Rig-Veda states that men and women are as corresponding as two wheels of a cart. Hand-carts pushed by humans have been used approximately the world. In the 19th century, for example, some Mormons traveling across the plains of the United States between 1856 and 1860 used handcarts.
Carts were often used for judicial punishments, both to transport the destined – a public humiliation in itself (in Ancient Rome defeated leaders were often carried in the victorious general's triumph) – and even, in England until its replacement by the whipping post under Queen Elizabeth I, to tie the condemned to the cart-tail and administer him or her a public whipping.

Lotion

A lotion is a low- to medium-viscosity medicated or non-medicated topical preparation intended for application to unbroken skin. Most lotions are oil-in-water emulsions but water-in-oil lotions are also formulated. Lotions are usually applied to external skin with a clean cloth, cotton wool or gauze. The key components of a lotion emulsion are the aqueous and oily phases, an emulgent to prevent separation of these two phases, and, if used, the drug substance or substances. A wide variety of other ingredients such as fragrances, glycerol, dyes, preservatives, vitamins, proteins and stabilizing agents are commonly added to lotions.

It is not uncommon for the same drug ingredient to be formulated into a lotion, cream and ointment. Creams are the most convenient of the three but are inappropriate for application to regions of hairy skin such as the scalp, while a lotion is less viscous and may be readily applied to these areas. Lotions also have an advantage in that they may be spread thinly compared to a cream or ointment and may economically cover a large area of skin. Non-comedogenic lotions are recommended for use on acne prone skin.

Unusual Twinnings

There are some patterns of twinning that are exceedingly rare: while they have been reported to happen, they are so unusual that most obstetricians or midwives may go their entire careers without encountering a single case. Among fraternal twins, in rare cases, the eggs are fertilized at different times with two or more acts of sexual intercourse, either within one menstrual cycle or, even more rarely, later on in the pregnancy. This can lead to the possibility of a woman carrying fraternal twins with different fathers. This phenomenon is known as heteropaternal super fecundation. One 1992 study estimates that the frequency of heteropaternal super fecundation among dizygotic twins whose parents were involved in paternity suits was approximately 2.4%; see the references section, below, for more details.

Among monozygotic twins, in extremely rare cases, twins have been born with opposite sexes. The probability of this is so vanishingly small that multiples having different genders are universally accepted as a sound basis for a clinical determination that in utero multiples are not monozygotic. When monozygotic twins are born with different genders it is because of chromosomal birth defects. In this case, although the twins did come from the same egg, it is incorrect to refer to them as genetically identical, since they have different karyotypes.

Biodiversity

Biodiversity or biological diversity is the diversity of life. There are a number of definitions and a measure of biodiversity. Biodiversity has no single standard definition. The most basic definition is "variation of life at all level of biological organization". Another definition holds that biodiversity is a measure of the relative diversity among organisms present in diverse ecosystems. "Diversity" in this definition includes diversity within a species and among species, and comparative diversity among ecosystems.

A third definition that is often used by ecologists is the "totality of genes, species, and ecosystems of a region". An advantage of this description is that it seems to describe most circumstances and present a unified view of the traditional three levels at which biodiversity has been identified.
