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

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

present computers are usually used in many walks of our life. What they mean for us? They have many applications in science‚ technology.

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

GCSE Graphic Products Revision guide SKETCHING TECHNIQUES Sketches of ideas and designs are the initial ideas of a product or object. They are very quick sketches to show shape and form. Annotations around the sketch help to explain how the design works. Sketching Enhancement There are many ways of enhancing your sketches these include: Thick & Thin line – the outline of a sketch is ‘lined-in’ to make the shape stand out.

Abstract This paper will outline the systems development life cycle as it pertains to both the development of a custom application and the selection of proprietary systems. The major types and classifications of health care information standards and specific organizations that develop and regulate standards will be explained. The need for security information systems will be revealed and the methods to accomplish security of these systems will be addressed. Three best practices for effective
