Night Runner Currently‚ there is a product on the market called the "Night Runner" ("Night Runner‚" n.d.). The Night Runner is a set of ultra-lightweight LED unit with front lights and rear tail light gives you 30 feet of hands-free illumination ("Night Runner‚" n.d.). They were initially designed for runners. However‚ they have other commercial uses as well. One of the commercial uses for the Night Runner is that it can be used by postal workers (Barbuti‚ 2016). The second commercial use is

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

Experiment 23: Synthesis of an Alkene April 5‚ 2013 Purpose: Results and Discussion The weight of our n-Butyl Bromide sample (actual yield) was 0.09g. The percent yield was found to be 4.38%. Only 0.09g of the theoretical 2.055g yield was obtained. The boiling point was 104° C‚ which is higher than the literature value of 101° C. This is due to the sample being somewhat impure‚ as impurities tend to increase boiling point. When IR spectroscopy was performed‚ there were no OH stretches

2.3. Characterization 2.3.1. FT-IR spectra The IR spectra of different powder were recorded using FT-IR Spectrometer‚ Spectrum RX1‚ USA. The samples were prepared in the pellet form by pressing their mixed powder with KBr by the ratio 1:10 in the Perkin Elmer hydraulic device. 2.3.2. UV-Vis absorption spectra measurement UV-Vis spectra were recorded in N‚ N-Dimethylformamide (DMF) in the range 200-800 nm. All the UV-vis measurements were accomplished by a Shimadzu PC3101 spectrophotometer‚ under

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
