Manufacturing of Aerogel Aerogel was found by Steven Kistler in 1931‚ but its application cannot be in the market and consumer because there is no item that can use the aerogel. The 1980s the aerogel have a place to be a raw material in existing and new product after they discover a new research about aerogel. They have been considered as a new development material that better than polyurethane foam in refrigerators‚ and as a heat insulator for windows. Aerogel is produced by removing all the

Short term memory (STM) Memory has been of interest since antiquity. For centuries memory was seen just as a storage system‚ however experimental research in the last century has identified several functions for memory such as: * Encoding * Storage * Retrieval * Processing information. Short term memory is also called * Primary memory (William James 1890) * Immediate memory * Working memory Free recall task (Murdock 1962) Participants had to remember

Effects of megasonic power in DIW rinsing on particle removal efficiency and defect density Abstract- As the IC fabrication feature size gets smaller‚ the particle removal process becomes a critical step. It was proven that megasonic in SC-1 chemical is effective in removing surface contaminants but might inflicting structure damage [1-2] especially for geometry smaller than 130nm technology. Since Moore’s law states that the number of transistor on an IC chip will be double every two years

Ben Jarrett University 1010 Mrs. Stubblefield 11/8/14 Practices of audio engineering have been around for over 125 years and in that time; much has changed. Audio engineering started with Thomas Edison’s recovering of Mary ’s Little Lamb from a strip of tinfoil wrapped around a spinning cylinder ("An Audio Timeline"). Though very simplistic and different from today’s audio engineering: still a form of recording music. The basic definition of audio engineering is a part of the field of engineering

old‚ as noted on Wikipedia‚ and it is still one of the most want to learn instruments out there today. There are 19 different types of guitars‚ but these 19 different types are grouped into 2 main groups‚ acoustic and electric. Some people would argue‚ because there is not a group for acoustic electric guitars‚ which is obviously a little of both of these groups. Electric guitars‚ introduced in the 1930s‚ rely on an amplifier that can electronically manipulate tone. Early amplified guitars were hollow
