Skin Layers 1. Epidermis The epidermis is the outer most layer of skin. It is built up of 5 layers (from the outside in) - stratum corneum is made of dead flat skin cells - stratum licidum - stratum granulosum - stratum spinosum - stratum basale Where cells divide and push previously formed cells into the upper layers. As the cells travel into the higher layers‚ they flatten and die‚ eventually. Specialized Epidermal Cells - melanocyte - produces pigment (melanin) - Langerhans’

Special Report Methyl ethyl ketone – A techno-commercial profile M ethyl ethyl ketone (MEK or 2-butanone) is an organic compound with the formula CH3C(O)CH2CH3. Its CAS number is 78-93-3. The colorless liquid ketone has a sharp‚ sweet odour of butterscotch and acetone. It is produced industrially on a large scale‚ and also occurs in trace amounts in nature. It is soluble in water and is commonly used as an industrial solvent. With natural and synthetic resins‚ MEK produces solutions with low viscosity

Layers of the Atmosphere The envelope of gas surrounding the Earth changes from the ground up. Five distinct layers have been identified using... • thermal characteristics (temperature changes)‚ • chemical composition‚ • movement‚ and • density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics‚ chemical composition‚ movement‚ and density occur. Troposphere The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20

BOUNDARY LAYER THEORY INTRODUCTION The concept of boundary layer was 1st introduced by L.Prandtl in 1904. Figure 7-1. Viscous flow around airfoil A structure having a shape that provides lift‚ propulsion‚ stability‚ or directional control in a flying object. Boundary layer is formed whenever there is a relative motion between the boundary and the fluid. Boundary layer thickness: 1. Standard thickness - signified by ‚” it is define as the distance from the boundary layer

and various trace gases make up the remainder. Scientists divided the atmosphere into four layers according to temperature: troposphere‚ stratosphere‚ mesosphere‚ and thermosphere. The temperature drops as we go up through the troposphere‚ but it rises as we move through the next layer‚ the stratosphere. The farther away from earth‚ the thinner the atmosphere gets. 1.TROPOSPHERE This is the layer of the atmosphere closest to the Earth’s surface‚ extending up to about 10-15 km above the Earth’s

the atmosphere‚ surrounds our planet. It provides us with the air we breathe‚ and it protects us from the full blast of the sun’s radiation. Way up in the part of the atmosphere‚ called the stratosphere‚ a layer of gas filters out most of the sun’s damaging ultraviolet rays. This layer of gas is called ozone and is located about five miles to 25 miles above the surface of the Earth. (Bright‚ 1991). Only about one-millionth of our atmosphere is made up of ozone. But it has a tremendously important

In the documentary‚ Dying to be Thin‚ dancers and regular people are asked about the pressure to be thin. This video has taught me that in our society being extremely skinny is considered beautiful. Not everyone is meant to be a size 2. It all depends on what your body type is. Everyone is beautiful no matter what size they wear. The word beautiful does not require the word skinny. Beauty is in the eye of the beholder. If you don’t see yourself as beautiful your confidence is very low.
