cause adverse change. Pollution can take the form of chemical substances or energy‚ such as noise‚ heat or light. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. There are 6 (six) types of pollution that are going to be discussed in this site‚ namely air‚ water‚ noise‚ land‚ radioactive‚ and thermal. Please proceed to the following links to learn anyone of

Sound and acoustics It is common to think that acoustics is the study of music. Although acoustics does comprise the study of musical instruments‚ it also includes an extensive range of topics‚ including: SONAR systems‚ noise control‚ ultrasounds for medical imaging and other processes‚ electroacoustic communication‚ seismology‚ etc. [1] In general‚ acoustics is the study of mechanical waves including sound‚ vibration‚ infrasound and ultrasound. When talking about the acoustics‚ it is essential

Mirror Lab One air inhalation hazard I observed during the Mirror Lab tour was for rhodite 906. In a large open room and workspace‚ the mirror lab utilized rhodite frequently to polish large new mirrors. This is concerning because this is a hazardous dust particle with its particle size at about 1.5 micrometers. The movement of these particles are heighted by water mist placed above the mirror to keep the rhodite from solidifying. The employees also sprayed down the mirror frequently which further

CS3282 Digital Comms 9.1 2 May’06 / BMGC Multi-level digital modulation & demodulation. 9.1. Introduction: So far‚ in looking at carrier modulated data transmission‚ we have concentrated mainly on binary signalling using simple forms of ASK‚ FSK and PSK. With a suitable pulse-shape‚ binary signalling can achieve a bandwidth efficiency of up to 2 bits/second per Hz using real unipolar pulses (base-band equivalent of ASK) or real bipolar pulses (base-band equivalent of PSK) at base-band.
