We all know that energy on earth is running out‚ but what if we could use stars? Stars contain so much energy‚ if we could harvest it‚ we would never run out of energy. Energy from stars could be the energy source we are looking for. Energy is something we probably take for granted‚ we use so much of it everyday‚ and our current energy source‚ fossil fuels‚ releases gases into the environment‚ but with energy from stars‚ it could be a fresh start for our energy sources and our environment.

Keloid Scar Treatments: Successful keloid treatment has still been an obstacle because the current treatments are far away from guarantying cure of the disease and preventing recurrence. This probably due to the lack of an extensive research to study and evaluate those treatments (Gauglitz et al.‚ 2011). There are a wide range of therapies that have been used in treating keloid and hypertrophic scars. Although most of the therapeutic options that we will cover work for both scars‚ we have to be very

Chapter 6 DIFFUSION IN SOLIDS • How does diffusion occur? • Why is it an important part of processing? • How can the rate of diffusion be predicted for some simple cases? • How does diffusion depend on structure and temperature? Driving force for movement In general‚ force is a position derivative of energy (F = - dE/dr). In other words‚ if there is any energy difference in space‚ there is a force which will act on matters - Force will move things. (ex1) Potential energy by gravity:

Contact lens is made up of plastic material and is directly placed on the anterior surface of eye to correct vision deficiences. Contact lens is used as substitution of spectacles. Currently‚ contact lens is more preferable as it comes in variety. One can change their eye color and appearance using colored pigment lens. The present methods of manufacturing includes mainly – Spin casting and Mold casting. But this has disadvantage of generation of ripple marks on the posterior surface and also distorted

reading silicon‚ based semiconductors revolutionized computing. Because silicone semi conductors are able to move freely through the solid component it is more efficient than copper based conductors. Silicone based conductors form holes which creates and fills a space continually. Meaning electrons jump from one atom to another. Also silicone is changed through a process called doping through adding either phosphorus or aluminum the desired effect is achieved. When phosphorus is added to silicon it become
