How To Perform Continuous Chest Compression (CPR)
2010-10-02 21:29:00 This post is a public service announcement and has not been paid for: How much do you know about Continuous Chest Compression (CPR)? The majority of us really have no clue as to how it is performed, at least not properly. It is always good to know how such a life saving procedure is performed because we may just be somewhere where someone suffers a cardiac arrest (heart attack) and we may be able to keep that person alive until the paramedics come along. Below is a video that shows how CPR is performed. It really is quite easy: If you want more information and resources on Chest-Compression-Only CPR, visit the Sarver Heart Center.

Deflection of tubing under compression
2009-07-21 00:13:00 This is possibly an overly-complicated way to deal with a problem - but I think it is the 'cleanest' way. For some grape vines, I installed two 4" round posts 2.5' into the ground, 30lbs of cement went into each hole at the bottom around the wood posts. They are 16' apart (actually... 189.5"), in

Powerful and small: MCE-5 Variable Compression Ratio engine
2008-04-10 21:06:00 Meet the MCE-5 VCR engine, coming at you from France. VCR stands for Variable Compression Rate, and its creators claim it will replace conventional Fixed Compression Rate engines. According to the press release (found after the jump), what is special about this engine is that it's based on a combination of rod-crank mechanism and long-life gears, integrating both power transmission and compression ratio control for each cylinder.MCE claims that this allows ratios from 7:1 to 20:1, which adapts the engine for most usage requirements. Oh, and this reduces fuel consumption by 30 percent, as two other prototypes of VCR engines showed by Saab and Audi in 2000. MCE also claims the design is more durable and robust, and will have lower maintenance costs.This engine has no impact on the rest of the components of a vehicle, so it's potentially installable in every sort of vehicle. MCE's current prototype offers 160 kW (218 HP) with a 1.5-liter engine.Gallery: MCE-5 VCR EnginePress Release...

Most peeps use compression, all the producers and beatmakers use Compression, doesn't matter if your Dre or anyone else, thery use compression... It makes your beats sound just a bit nicer... Terms to know: Attack: How fast a compressor will react once the threshold is breached. 0ms will result in immediate action. Decibles (db): Measure of sound pressure. Gain: Used to increase or decrease compressed sound. (measured in DB) Knee: A compressor characteristic that affects the way a compressor behaves. Milliseconds (ms): Attack and Release times measured by milliseconds. Ratio: How much a signal is compressed. With a compression ratio of 3:1, a signal which is 9db over the threshold level would be reduced to 3db. A signal of 3db over the threshold would be reduced to 1db....

Compression refrigeration cycle
2007-09-23 22:57:00 In the vapor-compression refrigeration cycle, heat is transferred from a lower temperature source to a higher temperature heat sink. Heat naturally flows in the opposite direction, and due to the second law of thermodynamics work is required to move heat from cold to hot. A food refrigerator or freezer works in much the same way; it moves heat out of the interior into the room in which it stands. This most common refrigeration cycle uses an electric motor to drive a compressor. In an automobile the compressor is usually driven by a belt connected to a pulley on the engine's crankshaft, with both using electric motors for air circulation. Since evaporation occurs when heat is absorbed, and condensation occurs when heat is released, air conditioners are designed to use a compressor to cause pressure changes between two compartments, and actively pump a refrigerant around. A refrigerant is pumped into the low pressure compartment (the evaporator coil), where, despite the low temperatu...
