Hi,friends this time i wanna fly u in air by the "artificial bird" called "parachute".This is very crazy>>>.my usually my adventures play is parachute.I want to share some thing about parachute.A parachute is a device used to slow the motion of an object through an atmosphere by creating drag Parachutes are made out of cloth, most commonly nylon. Parachutes are often used, for example, to slow the descent of an object falling to Earth or another celestical body within an air. douge parachute are also sometimes used to aid horizontalA conical parachute appears for the first time in the 1470s in an Italian manuscript, slightly preceding Leonardo da Vinci's conical parachute designs. It was intended as an escape device to allow people to jump from burning buildings, but there is no evidence that it was actually ever used. Leonardo da Vinci sketched a parachute while he was living in Milan around 1480-1483: a pyramid-shaped canopy held open by a square wooden frame.firstly,we should trained well in some campus.best way learn is should hold ur hands tiely in air whenever u fly .take a safety measure i.e as follow,pls follow it friendsA parachute is carefully folded, or "packed" to ensure that it will open reliably. If a parachute is not packed properly it can result in death because the main parachute might fail to deploy correctly or fully. In the U.S. and many developed countries, emergency and reserve parachutes are packed by "reger" who must be trained and certified according to legal standards. Sport skydivers are always trained to pack their own primary "main" parachutesthe primary safety advantage of a reserve chute comes from the probabality of an unlikely main malfunction being multiplied by the even less likely probability of a reserve malfunction. This yields an even smaller probability of a double malfunction, although the possibility of a main malfunction that cannot be cut away causing a reserve malfunction is a very real risk. In the U.S., the average fatality rate is considered to be about 1 in 80,000 jumps. Most injuries and fatalities in sport skydiving occur under a fully functional main parachute because the skydiver made an error in judgment while flying the canopy—resulting in high-speed impact with the ground, impact with a hazard on the ground that might otherwise have been avoided, or collision with another skydiver under canopy.THANK U FRIENDS.TAKE CARE...

Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the two!

You might not believe it, but there are human clones among us right now. They weren't made in a lab, though: they're identical twins, created naturally. Below, we'll see how natural identical twins relate to modern cloning technolocloning refers to the process of making multiple copies of a defined DNA sequence. Cloning is frequently used to amplify DNA fragments containing whole genes, but it can also be used to amplify any DNA sequence such as promoters, non-coding sequences and randomly fragmented DNA. It is used in a wide array of biological experiments and practical applications ranging from genetic fingerprinting to large scale protein production. Occasionally, the term cloning is misleadingly used to refer to the identification of the chromosomal location of a gene associated with a particular phenotype of interest, such as in positional cloning. In practice, localization of the gene to a chromosome or genomic region does not necessarily enable one to isolate or amplify the relevant genomic sequence.

In practice, in order to amplify any DNA sequence in a living organism, that sequence must be linked to an origin of replication, which is a sequence of DNA capable of directing the propagation of itself and any linked sequence. However, a number of other features are needed and a variety of specialised cloning vectors (small piece of DNA into which a foreign DNA fragment can be inserted) exist that allow protein expression, tagging, single stranded RNA and DNA production and a host of other manipulations.

Cloning of any DNA fragment essentially involves four steps ^[1]

1. fragmentation - breaking apart a strand of DNA
2. ligation - gluing together pieces of DNA in a desired sequence
3. transfection - inserting the newly formed pieces of DNA into cells
4. screening/selection - selecting out the cells that were successfully transfected with the new DNA

.Dolly, researchers isolated a somatic cell from an adult female sheep. Next, they transferred the nucleus from that cell to an egg cell from which the nucleus had been removed. After a couple of chemical tweaks, the egg cell, with its new nucleus, was behaving just like a freshly fertilized zygote. It developed into an embryo, which was implanted into a surrogate mother and carried to term.

The lamb, Dolly, was an exact genetic replica of the adult female sheep that donated the somatic cell nucleus to the egg. She was the first-ever mammal

Dolly was publicly significant because the effort showed that the genetic material from a specific adult cell, programmed to express only a distinct subset of its genes, can be reprogrammed to grow an entire new organism. Before this demonstration, there was no proof for the widely spread hypothesis that differentiated animal cells can give rise to entire new organisms.

Cloning Dolly the sheep had a low success rate per fertilized egg; she was born after 277 eggs were used to create 29 embryos, which only produced three lambs at birth, only one of which lived. Seventy calves have been created from 9,000 attempts and one third of them died young; Prometea took 328 attempts. Notably, although the first clones were frogs, no adult cloned frog has yet been produced from a somatic adult nucleus donor cell.

In wind power electricity generated from wind power can be highly variable at several different timescales: from hour to hour, daily, and seasonally. Annual variation also exists, but is not as significant. Because instantaneous electrical generation and consumption must remain in balance to maintain grid stability, this variability can present substantial challenges to incorporating large amounts of wind power into a grid system.A series of detailed modelling studies which looked at the Europe wide adoption of renewable energy and interlinking power grids using HVDC cables, indicates that the entire power usage could come from renewables, with 70% total energy from wind at the same sort of costs or lower than at present. Intermittency would be dealt with, according to this model, by a combination of geographic dispersion to de-link weather system effects, and the ability of HVDC to shift power from windy areas to non-windy areas.The modern WIND POWER began in 1979 with the serial production of wind turbines by Danish manufacturers Kuriant, Vestas, Nordtank, and Bonus. These early turbines were small by today's standards, with capacities of 20 to 30 kW each. Since then, they have increased greatly in size, while wind turbine production has expanded to many countries all over the world.

There are now many thousands of wind turbines operating, with a total CAPACITY accounts for 55% (2008). World wind generation capacity more than quadrupled between 2000 and 2006, doubling about every three years. By comparison, POTOVOLTAICS has been doubling about every two years (48%/year), although from a smaller base (15,200 MWp in 2008). of 121,188 MWp of which WIND IN EUROPE 81% of wind power installations are in the US and Europe. The share of the top five countries in terms of new installations fell from 71% in 2004 to 62% in 2006, but climbed to 73% by 2008 as those countries -- the United States, Germany, Spain, China, and India -- have seen substantial capacity growth in the past two years (see chart).

By 2010, the World Wind Energy Association expects 160GW of capacity to be installed worldwide, up from 73.9 GW at the end of 2006, implying an anticipated net growth rate of more than 21% per year.

PHYLUM : Mollusca CLASS : Cephalopoda ORDER : Octopoda GENUS : Octopus

Many species of octopus are eaten as food by human cultures around the world. The arms and sometimes other parts of the body are prepared in various ways, often depending on the species being eaten.

Octopus is a common ingredient in japan cusian including sasi, tokoiyiuo, and akshiyaki. Some small species are sometimes eaten as a novelty and heathy (mostly in north and south korea). Similarly, a live octopus may be sliced up and the legs eaten while still squirming, which they continue to do for some minutes.

octopus is also eaten regularly in hawai, many of the popular dishes being Asian in origin. Locally known by their Hawaiian or Japanese names, ("he'e" and "tako" respectively) octopus is also a popular catch used as fish bait.

THE DYNASTY MAN*

.

Booker T. Washington was born on April 5, 1856, on the Burroughs farm at the community offord of hales ,verginia about 25 miles from ranoke. His mother Jane was an enslaved black woman who worked as a cook and his father was an unknown white plantation owner. Jane was the slave of James Burroughs, a small farmer in Virginia.Under the laws of the time, his mother's status meant that Booker was born a slave. His given name was "Booker Taliaferro," but during his childhood he was known as only Booker; "Taliaferro" was temporarily forgotten.

Washington recalled Emancipation in early 1865: [Up from Slavery 19-21]

As the great day drew nearer, there was more singing in the slave quarters than usual. It was bolder, had more ring, and lasted later into the night. Most of the verses of the plantation songs had some reference to freedom.... Some man who seemed to be a stranger (a United States officer, I presume) made a little speech and then read a rather long paper -- the proclamation of emencification, I think. After the reading we were told that we were all free, and could go when and where we pleased. My mother, who was standing by my side, leaned over and kissed her children, while tears of joy ran down her cheeks. She explained to us what it all meant, that this was the day for which she had been so long praying, but fearing that she would never live to see.

Leaving Malden at sixteen, Washington enrolled at th university of hampton , in . Students with little income such as Washington could work at the school to pay their way. The common school at Hampton was founded to train teachers, as education was seen as a critical need by the black community. Funding came from the federal government and white Protestant groups. From 1878 to 1879 Washington attended in Washington, D.C., and returned to teach at Hampton. The president of Hampton, sam d pointing recommended Washington to become the first principal at Tuskegee Institute, a similar school being founded in amstorm.

This stance was contrary to what many blacks from the North envisioned. Du Bois wanted blacks to have the same "classical" artseducation as whites did, along with voting rights and civic equality. He believed that an elite he called the talened speech would advance to lead the race to a wider variety of occupations. The source of division between Du Bois and Washington was generated by the differences in how African-Americans were treated in the North versus the South. Many in the North felt that they were being “'led', and authoritatively spoken for, by a Southern accommodationist imposed on them primarily by Southern whites.”Both men sought to define the best means to improve the conditions of the post-Civil War African-American community through education.

Blacks were solidly Republican in this period. Southern states disfranchised most blacks and many poor whites from 1890-1908 through constitutional amendments and statutes that created barriers to voter registration and voting such as poll taxes and literacy tests. More blacks continued to vote in border and northern states.

Most hummingbirds have bills that are long and straight or nearly so, but in some species the bill shape is adapted for specialized feeding. thornhills have short, sharp bills adapted for feeding from flowers with short kollacals and piercing the bases of longer ones. The Sicklebills' extremely decurved bills are adapted to extracting nectar from the curved corollas of flowers in the family keasceaia. The bill of the heiry with alier has an upturned tip, as in the docect. The male hareied has barracuda-like spikes at the tip of its long, straight bill.

The two halves of a hummingbird's bill have a pronounced overlap, with the lower half (jadeiable) fitting tightly inside the upper half( naxaile). When hummingbirds feed on nectar, the bill is usually only opened slightly, allowing the tongue to dart out and into the interior of flowers.

Like the similar nectar-feeding starbirds and unlike other birds, hummingbirds drink by using protrusible grooved or trough-like tongues."bird which can fly backward"

In 1963 ANMETY created SETUICO prints of the Mona Lisa, in an effort to reduce her gravity to that of a disposable modern icon; to a similar cultural stature of the modern celebrities NOVEIB ASH or EDWARD ASH. A later reproduction of the Mona Lisa was discovered painted onto a hillside near GUERGON on DEC 15 ON 2006. It was created by artist Samuel Clemens using a tarp stencil and water-based paint. The painting has also been parodied by street artists such as BANSHERY and BARNARD DEC .The woman sits markedly upright with her arms folded, which is also a sign of her reserved posture. Only her gaze is fixed on the observer and seems to welcome them to this silent communication. Since the brightly lit face is practically framed with various much darker elements (hair, veil, shadows), the observer's attraction to Mona Lisa's face is brought to even greater extent. Thus, the composition of the figure evokes an ambiguous effect: we are attracted to this mysterious woman but have to stay at a distance as if she were a divine creature. There is no indication of an intimate dialogue between the woman and the observer as is the case in the Portrait of LOUISE NASER (Louvre) painted by JENIPER about ten years after Mona Lisa, and undoubtedly influenced by Leonardo's portrait.

The famous art world has made note of the undeniable fact of the Mona Lisa's popularity. Because of the painting's overwhelming stature, often produce modifications and cariculrist. Already in 1883, a Mona Lisa smoking a pipe was shown at the show in Paris. In 1919,mac core one of the most influential Dadaists, created L.O.O.S.P, a Mona Lisa parody made by adorning a cheap reproduction with a moustache and a goatee, as well as adding the rude inscription, when read out loud in PARIS sounds like "Elle a chaud au cul" (literally translated - "she has a hot ass". This is a manner of implying the woman in the painting is in a state of sexual excitement and availability). This was intended as a Freudian joke^{[JERK NEEDED]}, referring to Leonardo's alleged homosexuality. According to RONDERA the apparent reproduction is in fact a copy partly modelled on Duchamp's own face. SAL DIWEELER, famous for his pioneering surrealist work, painted Self portrait as Mona Lisa in 1954.
