Transmission Fluid - Your car will rely on many things especially fluids to keep all the mechanical parts well lubricated and working without using much heat on high-friction functions. Transmission fluid is one of the most important fluids in the car. Significance The transmission system uses clutch, actuating shafts and all the gear connections. Each engine gear will have a limit, which is defined by the red line that is always defined by the revolutions per minute. When the gear of your vehicle reaches the limit, it has to stop spinning and let another gear power the vehicle....   [tags: Automobiles] 1058 words

Energy Transmission - In energy systems where the energy-collection process in an energy-material is needed as a step physically separated from the Processing Unit, the transportation of the energy-material that contains the energy is required. In the case of biomass-based energy systems, this step encompasses all the infra-structure associated with the logistics of supplying biomass to the Processing Unit: machines, roads, pipes, etc. Although the energy that flows through this stage is tied to the amount of raw material demanded by the processing plant, its cost structure may vary freely, dependent upon the type of transportation technology adopted (i.e.: pipelines, trucks, railroads), distances, daily demand of the processing unit, operation time, and physical characteristics of the raw material (as density)....   [tags: Energy] 869 words

The Principles and Limitations of Transmission and Scanning Electron Microscopes - The Principles and Limitations of Transmission and Scanning Electron Microscopes Introduction Microscopy has a major role in cytology.From the very beginning researchers have tried to develop ways of looking directly at living cells.This examination has revealed much about the morphology of cells and tissues.In recent years,development in microscopes,dyes,staining and preparatory techniques have helped reveal even more about the structure and function of cells.Microscopes have a certain magnification and resolving power.In any microscope the the resolving power is more important than the magnification.The resolving power of a microscope is the least distance between two objects where the microscope can still distinguish the objects as being separate.It is a measure of detail that can be seen.A microscope with a high resolving power enables us to view images with a high resolution.With a low resolution they would be viewed as one object.Microscopes with a high magnification are only able to increase the size of the object that is being viewed.The resolution will be the same.(ie the object will still lack clarity and appear fuzzy).The two types of microscopes are electron and light microscopes....   [tags: Papers] 850 words

What is ATM? - What is ATM. Before the discussion of wireless ATM can begin, the concept of ATM in general needs to be discussed. ATM, or by its more formal name Asynchronous Transfer Mode, is a basic packet-based networking system designed for the simultaneous transmissions of voice, video, and data. In the mid 1980s, the major telecommunication companies decided that they needed a new network to handle the surge of video and data, along with voice, traffic being sent over their existing networks. From this, the concept of ATM was born....   [tags: ATM Asynchronous Transfer Mode Research Essays]
