Birds

Many species of bird undertake long distance annual migrations, and many more perform shorter irregular movements. Birds are social and communicate using visual signals and through calls and song, and participate in social behaviors including cooperative hunting, cooperative breeding, flocking and mobbing of predators. Birds are primarily socially monogamous, with engagement in extra-pair copulations being common in some species-other species have polygamous or polyandrous breeding systems. Eggs are regularly laid in a nest and incubated and most birds have an extended period of parental care after hatching.

Birds are economically important to humans: many are important sources of food, acquired either through hunting or farming, and they provide other products. Some species, particularly songbirds and parrots, are popular as pets. Birds figure prominently in all aspects of human culture from religion to poetry and popular music. About 120-130 species have become extinct as a result of human activity since 1600, and hundreds more before this. Currently around 1,200 species of birds are threatened with extinction by human activities and efforts are underway to protect them.

Shipping

Shipping is basic method of transporting goods and cargo. Virtually every product ever made, bought, or sold has been exaggerated by shipping. Despite the lots of variables in shipped products and locations, there are only three basic types of shipments, land, air, and sea.

Land or ground shipping can be either by train or by automobile. Trucking is easily the most accepted form of shipping. Even in Air and Sea shipments, ground transportation is still required to take the product from its origin to the airport or seaport and then to its purpose. Ground transportation is typically more affordable than air shipments, but more costly than shipping by sea. Trucks are also much quicker than ships and rail but slower than planes.

Ground shipping can be cheaper and less limiting to size, quantity, weight, and type of freight than by air transport. Air transport is usually held in reserve for products which must be sent within a shorter time frame. Shipping can more generally refer to the transport of freight, self-determining of the mode of transport.

Papaya

The papaya is a fruit of the tree. It is a small tree, the single stem growing from 5 to 10 m tall, with spirally set leaves confined to the top of the trunk, the lower trunk is obviously scarred where leaves and fruit were borne. The leaves are large, 50-70 cm width, deeply palmately lobed with 7 lobes. The tree is typically unbranched if unlopped. The flowers are similar in shape to the flowers of the Plumeria but are much slighter and wax like. They appear on the axils of the leaves, maturing into the large 15-45 cm long and 10-30 cm diameter fruit. The fruit is ripe when it feels soft and its skin has attained amber to orange hue. The fruit's taste is vaguely similar to pineapple and peach, although much milder without the tartness, creamier, and more fragrant, with a texture of a little over-ripened cantaloupe.

The primary use of the papaya is as an safe to eat fruit. The ripe fruit is generally eaten raw, without the skin or seeds. The unripe green fruit of papaya can be eaten ripe, usually in curries, salads and stews.

Computation

Computation is a common term for any type of information processing that can be represent mathematically. This includes phenomenon ranging from simple calculations to human idea. In a more narrow meaning, computation is a process following a well distinct model that is understood and can be expressed in an algorithm, protocol, network topology, etc.

This hypothetical computing equipment can be viewed as idealized analog computers which operate on real numbers and are differential, whereas digital computers are partial to computable numbers and are algebraic. Depending on the model select, this may enable real computers to solve problems that are inextricable on digital computers.

Computers

Computers take numerous physical forms. The first devices that resemble modern computers date to the mid-20th century, although the computer concept and various machines similar to computers existed prior. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. Modern computers are based on comparatively tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space. Today, simple computers may be made small enough to fit into a wrist watch and be powered from a watch battery. Personal computers in various forms are icons of the information age and are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices-for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.

The ability to store and execute lists of instructions called programs makes computers extremely versatile and distinguishes them from calculators. The Church-Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks given enough time and storage capacity.

Air Condition

The name air conditioning most commonly refers to the cooling and dehumidification of indoor air for thermal relieve. In a broader sense, the term can refer to any form of cooling, heating, ventilation or disinfection that modifies the condition of air. An air conditioner (AC or A/C in North American English, aircon in British and Australian English) is an appliance, system, or mechanism designed to stabilise the air temperature and moisture within an area (used for cooling as well as heating depending on the air properties at a set time) , typically using a refrigeration cycle but sometimes using desertion, most commonly for comfort cooling in buildings and carrying vehicles.

The concept of air conditioning is known to have been applied in primordial Rome, where channel water was circulated through the walls of certain houses to cool them. Similar techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the sizzling season. Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier.

Leopard

Large wild cat found in Africa and Asia. The background colour of the fur is golden, and the black spots form rosettes that differ according to the mixture; black panthers are simply a colour distinction and retain the patterning as a ‘watered-silk’ effect. The leopard is 1.5–2.5 m/5–8 ft long, including the tail, which may measure 1 m/3 ft. (Species Panthera pardus, family Felidae.)

The snow leopard or ounce (Panthera uncia), which has irregular rosettes of much larger black spots on a light cream or grey background, is a native of mountains in central Asia. The clouded leopard (Neofelis nebulosa) is rather smaller, about 1.75 m/5.8 ft overall, with large blotchy markings rather than rosettes, and is found in Southeast Asia. There are seven species, of which six are in danger of extinction, including the Amur leopard and the South Arabian leopard. One subspecies, the Zanzibar leopard, may already be extinct. The last Judean desert leopard died May 1995, although a small population survives in the Negev Desert.

Coconut

The coconut palm is grown throughout the tropical world, for decoration as well as for its many cooking and non-culinary uses, virtually every part of the coconut palm has some human use.The flowers of the coconut palm are polygamomonoecious, with both male and female flowers in the similar inflorescence. Flowering occurs continuously, with female plants producing seeds. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating. Coconut water can be used as an intravenous fluid.

Nearly all parts of the coconut palm are useful, and the palms have a comparatively high yield, it therefore has important economic value. The name for the coconut palm in Sanskrit is kalpa vriksha, which translates as the tree which provides all the requirements of life. In Malay, the coconut is known as pokok seribu guna, the tree of a thousand uses. In the Philippines, the coconut is generally given the title Tree of Life. The white, fleshy part of the seed is safe to eat and used fresh or dried in cooking.

Inductor

An inductor is a passive electrical device working in electrical circuits for its property of inductance. Inductance is an consequence which results from the magnetic field that forms around a current carrying conductor. Electrical current through the conductor creates a magnetic flux relative to the current. A change in this current creates a change in magnetic flux that, in turn, generates an electromotive force that acts to oppose this change in current. Inductance is a calculate of the generated emf for a unit modify in current. An inductor with an inductance of 1 henry produces an emf of 1 V when the current through the inductor changes at the rate of 1 ampere per second. The number of turns, the area of each loop/turn, and what it is wrapped around influence the inductance.

An inductor opposes changes in the current. An ideal inductor would offer no resistance to a constant direct current, however, only superconducting inductors have truly zero electrical resistance. Inductors are used expansively in analog circuits and signal processing.
