PPT ON ENGINEERING DRAWING

An engineering drawing, a type of technical drawing, is used to fully and clearly define requirements for engineered items.

Engineering drawing (the activity) produces engineering drawings (the documents). More than just the drawing of pictures, it is also alanguage—a graphical language that communicates ideas and information from one mind to another.^[1] Most especially, it communicates all needed information from the engineer who designed a part to the workers who will make it.

PPT on boiler or steam generator

A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (1–300 psi/0.069–20.684 bar; 6.895–2,068.427 kPa) but, at pressures above this, it is more usual to speak of a steam generator.

PPT on Compton effect

In physics, Compton scattering is a type of scattering that X-rays and gamma rays (both photons with different energy ranges) undergo in matter. Theinelastic scattering of photons in matter results in a decrease in energy (increase in wavelength) of an X-ray or gamma ray photon, called the Compton effect. Part of the energy of the X/gamma ray is transferred to a scattering electron, which recoils and is ejected from its atom (which becomes ionized), and the rest of the energy is taken by the scattered, "degraded" photon. Inverse Compton scattering also exists, in which a charged particle transfers part of its energy to a photon.

PPT ON GLOBAL WARMING

Global warming is the rising average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's average surface temperature has increased by about 0.8 °C (1.4 °F), with about two thirds of the increase occurring since 1980.^[Warming of the climate system is unequivocal, and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels.These findings are recognized by the national science academies of all major industrialized nations.

Carbon cycle

The carbon cycle is the biogeochemical cycle by which carbon is exchanged between the biosphere, geosphere, hydrosphere and atmosphere of the Earth.

COMMUNICATION SKILL PPT

Communication Skills – Start Here! Why you need to get your message across Effective communication is all about conveying your messages to other people clearly and unambiguously. It’s also about receiving information that others are sending to you, with as little distortion as possible. Doing this involves effort from both the sender of the message and the receiver. And it’s a process that can be fraught with error, with messages muddled by the sender, or misinterpreted by the recipient. When this isn’t detected, it can cause tremendous confusion, wasted effort and missed opportunity. In fact, communication is only successful when both the sender and the receiver understand the same information as a result of the communication. By successfully getting your message across, you convey your thoughts and ideas effectively. When not successful, the thoughts and ideas that you actually send do not necessarily reflect what you think, causing a communications breakdown and creating roadblocks that stand in the way of your goals – both personally and professionally. In a recent survey of recruiters from companies with more than 50,000 employees, communication skills were cited as the single more important decisive factor in choosing managers.
