Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) between the start and the end of the 20th century. The Intergovernmental Panel on Climate Change (IPCC) concludes that most of the observed temperature increase since the middle of the 20th century was caused by increasing concentrations of greenhouse gases resulting from human activity such as fossil fuel burning and deforestation. The IPCC also concludes that variations in natural phenomena such as solar radiation and volcanism produced most of the warming from pre-industrial times to 1950 and had a small cooling effect afterward. These basic conclusions have been endorsed by more than 40 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries.Climate model projections summarized in the latest IPCC report indicate that the global surface temperature will probably rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century. The uncertainty in this estimate arises from the use of models with differing sensitivity to greenhouse gas concentrations and the use of differing estimates of future greenhouse gas emissions. Some other uncertainties include how warming and related changes will vary from region to region around the globe. Most studies focus on the period up to the year 2100. However, warming is expected to continue beyond 2100 even if emissions stop, because of the large heat capacity of the oceans and the long lifetime of carbon dioxide in the atmosphere.
An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts. The continuing retreat of glaciers, permafrost and sea ice is expected, with warming being strongest in the Arctic. Other likely effects include increases in the intensity of extreme weather events, species extinctions, and changes in agricultural yields.
Political and public debate continues regarding climate change, and what actions (if any) to take in response. The available options are mitigation to reduce further emissions; adaptation to reduce the damage caused by warming; and, more speculatively, geoengineering to reverse global warming. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions.

The word originates from the Greek word "stadion" a Greek measure of length roughly 180 - 200m. The oldest known stadium is the one in Olympia, in western Peloponnese, Greece, where the Olympic Games of antiquity were held since 776 BC. Initially 'the Games' consisted of a single event, a sprint along the length of the stadium. Therefore the length of the Olympia stadium was more or less standardized as a measure of distance (approximately 190 meters or 210 yd). The practice of standardizing footrace tracks to a length of 180-200 meters (200-220 yd) was followed by the Romans as well. Greek and Roman stadia have been found in numerous ancient cities, perhaps the most famous being the Stadium of Domitian, in Rome.Dome stadia are distinguished from conventional stadia by their enclosing roofs. They are called stadia because they are large enough for, and designed for, what are generally considered to be outdoor sports. Those designed for what are usually indoor sports are called arenas. Some stadia have partial roofs, and a few have even been designed to have moveable fields as part of the infrastructure.

g, colloquially referred to as "26-inch", although the term is inaccurate as it covers too many rim and tyre sizes to be meaningful. Wheels used on mountain bikes usually use wide, knobby tires for good traction on uneven terrain and shock absorption. In the current century front wheel suspension has become the norm and full front and rear suspension has become increasingly common. Some mountain bikes are also fitted with bar ends on the handlebars to give extra leverage for hill-climbing.
Jungle refers to the most dense, more or less impenetrable regions within a tropical rainforest with an abundance of animal and plant life. The word jungle originates from the Sanskrit word jangala which refers to uncultivated land, among other meanings. The term is prevalent in many languages of the Indian subcontinent and particularly Urdu and Hindi.
The sky is the part of the atmosphere or of outer space visible from the surface of any astronomical object. It is difficult to define precisely for several reasons. During daylight, the sky of Earth has the appearance of a deep blue surface because of the air's scattering of sunlight.The sky is sometimes defined as the denser gaseous zone of a planet's atmosphere. At night the sky has the appearance of a black surface or region scattered with stars.

lf an hour of more selective feeding. In this time, the rabbit will also excrete many hard fecal pellets, being waste pellets that will not be reingested. If the environment is relatively non-threatening, the rabbit will remain outdoors for many hours, grazing at intervals. While out of the burrow, the rabbit will occasionally reingest its soft, partially digested pellets; this is rarely observed, since the pellets are reingested as they are produced. Reingestion is most common within the burrow between 8 o'clock in the morning and 5 o'clock in the evening, being carried out intermittently within that period.
nt is commonly known as the hard worker who has the capacities to struggle and can fight against the problems. Students are the future of world and the world depends upon the students. The world feels proud when it is treated by students. All the peoples in the world are students. Noone can think that he/she is not a student and hasn't got the rights to do some works for the better future of world. Every poeple has got rights and it is natural, not maintained by peoples and every one has to do struggle.
Oseltamivir (INN) (pronounced is an antiviral drug that slows the spread of influenza (flu) virus between cells in the body by stopping the virus from chemically cutting ties with its host cell. The drug is sold under the trade name Tamiflu and is taken orally in capsules or as a suspension. It has been used to treat and prevent Influenzavirus A and Influenzavirus B infection in over 50 million people since 1999.[citation needed] Oseltamivir becomes active in the body once it passes through the liver.

hen i must not think that our mind is not working because for eg; suppose there are 30 students in a class and they all are doing hard work and all of thems personality is good then also it is not possible for all of them to be first in examination.. isn't it? The one whose every performance touches the heart as well as mind gets the first prize. Likewise we must be true to what we are doing and what we are going to do in future. Another example: if i want to drive a scooter and i didn't have it then am i doing true by not taking its training? It was set in my mind that by the time i buy a scooty, i'll start taking its training. But i was absolutely wrong at all because the training means to be perfect. For eg; if some person wants to be a pilot but he doesn't have it then what he will never take its training??? No he will permanently take his training.Whether we have the things or not, we should take an training of differeht things because it not only maintains our friendly environment, it also helps to be full of skills. So at last i just want to say that if u have an idea of something then just drop on it... I am sure u'll be the great person on the world and get success. So chill your life and be blessed by all your wellwishers....
Ganesha's earliest name was Ekadanta (One Tusk), referring to his single whole tusk, the other having been broken off. Some of the earliest images of Ganesha show him holding his broken tusk. The importance of this distinctive feature is reflected in the Mudgala Purana, which states that the name of Ganesha's second incarnation is Ekadanta. Ganesha's protruding belly appears as a distinctive attribute in his earliest statuary, which dates to the Gupta period (fourth to sixth centuries). This feature is so important that, according to the Mudgala Purana, two different incarnations of Ganesha use names based on it: Lambodara (Pot Belly, or, literally, Hanging Belly) and Mahodara (Great Belly). Both names are Sanskrit compounds describing his belly (Sanskrit: udara). The Brahmanda Purana says that Ganesha has the name Lambodara because all the universes (i.e., cosmic eggs; IAST) of the past, present, and future are present in him. The number of Ganesha's arms varies; his best-known forms have between two and sixteen arms. Many depictions of Ganesha feature four arms, which is mentioned in Puranic sources and codified as a standard form in some iconographic texts. His earliest images had two arms. Forms with 14 and 20 arms appeared in central India during the 9th and 10th centuries. The serpent is a common feature in Ganesha iconography and appears in many forms. According to the Ganesha Purana, Ganesha wrapped the serpent Vāsuki around his neck.
Other depictions of snakes include use as a sacred thread (IAST: yajñyopavīta) wrapped around the stomach as a belt, held in a hand, coiled at the ankles, or as a throne. Upon Ganesha's forehead there may be a third eye or the Shaivite sectarian mark (Sanskrit: tilaka), which consists of three horizontal lines. The Ganesha Purana prescribes a tilaka mark as well as a crescent moon on the forehead. A distinct form of Ganesha called Bhalachandra (IAST: bhālacandra; "Moon on the Forehead") includes that iconographic element. Specific colors are associated with certain forms. Many examples of color associations with specific meditation forms are prescribed in the Sritattvanidhi, a treatise on Hindu iconography. For example, white is associated with his representations as Heramba-Ganapati and Rina-Mochana-Ganapati (Ganapati Who Releases from Bondage). Ekadanta-Ganapati is visualized as blue during meditation on that form. Ganesha is considered to be the Lord of letters and learning.
In Sanskrit, the word buddhi is a feminine noun that is variously translated as intelligence, wisdom, or intellect. The concept of buddhi is closely associated with the personality of Ganesha, especially in the Puranic period, when many stories stress his cleverness and love of intelligence. One of Ganesha's names in the Ganesha Purana and the Ganesha Sahasranama is Buddhipriya. This name also appears in a list of 21 names at the end of the Ganesha Sahasranama that Ganesha says are especially important. The word priya can mean "fond of", and in a marital context it can mean "lover" or "husband", so the name may mean either "Fond of Intelligence" or "Buddhi's Husband".












Aeronautics (from Greek aero which means air or sky and nautis which means sailor, i.e. sailor of the air or sky) is the science involved with the study, design, and manufacture of flight-capable machines, or the techniques of operating aircraft. While the term—literally meaning "sailing the air"—originally referred solely to the science of operating the aircraft, it has since been expanded to include technology, business and other aspects related to aircraft.One of the significant parts in aeronautics is a branch of physical science called aerodynamics, which deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft. Aviation is a term sometimes used interchangeably with aeronautics, although "aeronautics" includes lighter-than-air craft such as airships, while "aviation" does not.
