A SEMINAR REPORT ON AGEING OF BITUMEN ABSTRACT Bitumen is a common binder and has gradually replaced road tar for construction purposes mainly because of the cancer risk. It is a mixture of organic liquids that are highly viscous‚ black‚ sticky and entirely soluble in carbon disulfide. The ageing of bitumen is a complex process based on the chemical composition of the bitumen‚ the pavement structure and climate. It leads to deterioration of pavements and leads to loss of adhesive

The detection out of the visible spectrum is usually an adaptation for survival of the organism. Humans detection

The world as a whole currently faces several dramatic problems. Examples of these world problems include terrorism‚ desertification‚ overpopulation‚ deforestation‚ pollution‚ and world hunger. Of all these world problems the two that should currently be focused on are deforestation and pollution. Millions of acres of forests are chopped down by large lumber companies for the means of economic success. The world’s air and water is constantly polluted by dangerous machinery emissions and factorial

Danielle Silverstein PHY 101 Section 10497 March 4‚ 2013 Light up this World Purpose: In this lab experiment‚ LED lights will be used to show how when E&M radiation is absorbed‚ the energy is converted to heat. A drop of isopropyl alcohol will absorb light energy of different colors‚ and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs

TITLE CONTACTLESS TACHOMETER ABSTRACT: The aim of the project is to design a contactless speed sensing device (tachometer) for a motor. Traditional tachometers require a physical contact to the shaft of the motor to measure the speed. In certain applications‚ where it is not possible to measure the speed directly‚ it is possible for a contactless tachometer to take the readings from a certain distance. This is the main motivation behind choosing this project. This contactless tachometer

Tachyon particles are theoretical particles that supposedly have a minimum speed of the speed of light. Tachyons‚ (from the greek word ‘tachys’‚ meaning swift)‚ have never been found in experiments‚ but scientists think that they exist as faster-than-light “quasiparticles”. In the 1960s‚ some physicists wondered what would happen if matter could travel faster than the speed of light‚ something that is supposed to be impossible according to Einstein’s Theory of Special Relativity. Tachyons were first

Name : Joanne Wong Student ID : 00000012636 (BM1/14) Title : Spectrophotometer and its function Introduction Spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.[1] It can measure any of the listed light ranges that usually cover around 200 nm - 2500 nm using different controls and calibrations. [1] There are a few types of spectrophotometer such as calorimeter‚ UV spectrometer‚ IR spectrometer‚ atomic
