The Life Cycles of Stars In the universe‚ there are hundreds of billions of stars. They are formed when gas and dust from space "clump" together. As the mass grows larger‚ gravity takes over and a core begins to form. The core becomes extremely dense and this compaction causes temperatures within it to rise to the point where nuclear fusion (the burning of hydrogen in a chain reaction) can begin. The heat generated by fusion can reach 24 million degrees F (Fahrenheit). "That amount of heat keeps

the core as a gaseous shell. The gas that surrounds the core is called a "Planetary Nebula". The core that is left then becomes a "white dwarf". After the white dwarf cools down enough it stops shining and dies‚ forming a "black dwarf". Another life cycle of a star involves a star with a mass of 10 solar masses or more. These stars evolve similarly to stars of about 1 solar mass until they reach "main sequence". The star shines bright until all of its hydrogen has fused to form helium. This takes

Rubicon Consulting mike@rubiconconsulting.com Abstract: Innovation competencies are valuable in emergent and high-growth phases of the lifetime of a product or industry segment. For mature industries‚ researchers have emphasized strengths in operations and execution‚ with the implication that innovation-oriented companies must enter early in the product lifecycle or not at all. Here we examine the decision of Apple Inc. to enter the mobile handset business. We link the iPhone entry strategy to its

Eventually though a passing star or shock wave from a supernova will disturb the gas and dust. The dust and gas may then start to clump together‚ gravity will then clump more and more gas together‚ this is when the star starts the next part of its life cycle. Protostar: A protostar is when the gas has clumped together and it getting hot but has not reached what is known as critical mass. At this point the gas will be hot enough to glow. but since there is still a large amount of dust su

Organizational life cycle Prof.univ.dr. Ion Gh. ROŞCA Prof.univ.dr. George MOLDOVEANU Academ de Studii Economice din Bucureşti Abstract This paper proposes an analogy between rational biological model and the organizations’ development during their existence. So‚ organizations’ "born" or creation are considered the result of genetic algorithms‚ transformations are identified with changes that aim the adapting to the environment‚ and finally the ”death” treats the state of

LIFE CYCLE OF A STAR Stars are formed in nebulae‚ interstellar clouds of dust and gas (mostly hydrogen). These stellar nurseries are abundant in the arms of spiral galaxies. In these stellar nurseries‚ dense parts of these clouds undergo gravitational collapse and compress to form a rotating gas globule. The globule is cooled by emitting radio waves and infrared radiation. It is compressed by gravitational forces and also by shock waves of pressure from supernova or the hot gas released

Nintendo History Nintendo was founded in 1889. It was a poker card workshop. But now it’s Japan’s most famous game production company. Its production of electronic games are popular all around the world. Nintendo is the NO.1 of the world’s video game companies. With only 850 staffs‚ Nintendo used to beat such super enterprises as Toyota occasionally‚ thus becoming Japanese first profit-making company. Nintendo spells “Wii” with two lower-case “I” characters means: To resemble two people
