Environment and pollution in CSR Introduction There are different type of pollution that affect the environment for example: Water pollution‚ Air pollution Land pollution Noise pollution and Radioactive pollution. Water pollution Water pollution is the pollution of water bodies for example ‚ rivers‚ oceans‚ aquifers‚ lakes and groundwater. Also there are some undesirable substances pollute the water. Moreover there are many cases of water pollution one of the themes is Industrial

The time for one orbit is called the period. 6. The angle of inclination of a satellite is 0 degrees if it orbits over the equator and is 90 degrees if it orbits over the north and south poles. 7. To prevent excessive signal attenuation and noise in the atmosphere‚ satellite angles of elevation of less than 5 degrees should be avoided. 8. A satellite that rotates around the equator 22‚ 300 mi from the earth is said to be in geosynchronous or geostationary orbit. 9. Small jet thrusters

the power density spectral of noise measurements at low frequencies‚ from 1 Hz to 14 Hz and used commercial resistance of 1 kΩ to compare 2 different current generators. The curves in red color correspond KEITHLEY 2400 series and the curves in black color correspond to the ADRET current generator. The KEITHLEY generator slightly lower noise than ADRET generator. However‚ theoretically the differential measure with correct polarization can suppress this kind of noise origin from the current generator

reduce noise at various frequencies due to the numerous chambers and changes in geometry that the exhaust gasses are forced to pass through. The sole purpose of an automotive muffler is to reduce engine noise emission. If you have ever heard a car running without a muffler you will have an appreciation for the significant difference in noise level a muffler can make. If vehicles did not have a muffler there would be an unbearable amount of engine exhaust noise in our environment. Noise is

on Environmental Pollution Land pollution‚ water pollution‚ Air pollution & noise pollution in environment is called Environmental pollution. 1.Air pollution When dust particles and smoke mixed in the air‚ the air becomes dirty. This is called air pollution. The dirty air makes many people sick. 2. Water pollution When waste mixed with water‚ the water becomes dirty. This is called water pollution. The dirty water makes diseases. 3.Land pollution When Iron‚ paper‚ rubber‚ bags

perpendicular the wires are to each other the induced current will be less. Noise What is noise? Anything electrical in the cable that isn’t the signal is noise. Does a small amount of noise negatively affect the signal? With noise your signal will be distorted. As the noise increases‚ what happens to the signal? As the noise increases the signal increases What happens to the network when Noise is uncontrolled? Uncontrolled noise will overpower the data signal and breakdown the network. Frequency/Bandwidth

sounds from other instruments‚ or to provide "drier" rooms for recording vocals or quieter acoustic instruments. Dead Room A lot of studios pride themselves in having a ‘dead’ room. What does this that mean? * It’s free and clear of ambient noise * It has enough treatments in it to soak up any sound made in the room (so as not to hear an echo). When recording at home‚ sometimes it’s hard to

Definition Of Air PollutionAir pollution occurs when the air contains gases‚ dust‚ fumes or odour in harmful amounts. That is‚ amounts which could be harmful to the health or comfort of humans and animals or which could cause damage to plants and materials.The substances that cause air pollution are called pollutants. Pollutants that are pumped into our atmosphere and directly pollute the air are called primary pollutants. Primary pollutant examples include carbon monoxide from car exhausts and sulfur
