productivity is how much you get done, efficiency is what you complete/how much effort you put in. so if you can do something easily and in a timely manner then it was efficient, if you got a lot done you were productive. you can be both.

use near-infrared spectroscopy

yes

In deffered database the transaction is committed after the transaction is completed i.e(the transaction has completed its partially committed state) where as for immediate database the transaction is commited when tha transaction is in the active state. keta shah Oracle DBA track trainer ITS knp_shah@yahoo.co.in

Flash sterilization is a process used to clean objects. Rapid penetration of steam is used to sterilize and clean the items.

Isn't it 7,601 FEET above sea level? It certainly isn't metres given that Denali is 6,194m.

good use is to demolish the structure

Yes, you can plug two mice into your computer at the same time... however both mice will control the same pointer on screen. At this moment there seems to be no easy way to set the computer to accept two mice each with there own pointer. I did some research on this a week ago.

Ageing is what happens over time to the material; vulcanization is a process whereby something hardens.

Modern day commercial jets have separate Auxiliary Power Units, or APUs. These are used to supply electrical, hydraulic, and pneumatics while on the ground and, if needed for emergency back-up, in the air. The main engines, once started, are capable of supplying all of these needs in addition to the required thrust for flight. Under some conditions, pneumatics from the main engines may be reduced or shut off during takeoff or emergency conditions to increase available thrust to the engines. Modern commericial jets extract bleed air from the engines to operate the air packs that provide heat to the cabin during its flight. On most engines that I deal with, this bleed air is taken from two locations on the engine compressor: a low-pressure and a high-pressure stage of the engine. The low-pressure stage is about Stage # 7 or up to #10 and the high-pressure air is taken from Stage #14. The high-pressure bleed air is used for most normal demand and the low-pressure is used for peak demand. Engine description: Most commericial jet engines are high-bypass turbojet engines. The first stage is the large fan in front and then there are successives rows of blades that compress the air which increases the air pressure and temperature. After passing through the compressor stages, fuel is injected and the air/fuel mixture is ignited and the explanding gases go through another series of rows or the turbine stages. During take-off, the aircraft will shut off the bleed air so that the engine can produce its maximun thrust. I understand your Question to mean: What percentage of bleed air is extracted from the engines during normal operation? More of the answer to follow.

The difference between an institute and a training center is the length of time the student has to study there to gain a degree. Another difference might be that the institute offers several different classes and the training center has only one type of training. A truck driver school might be a training center if it is separate from the institute.

Nope, longitudinal.

Force (load) = Pressure X Area

Your question doesnt make sense...

Different symbols are used but if you are referring to the greek symbol "σ", it is pronounced "sigma" (like stigma without the t).

Recording engineers operate and maintain sound recording equipment. They may also work special effects equipment. These engineers install, test, repair, set up and operate the electronic equipment used to record and transmit radio signals.They regulate the signal strength, clarity and range of sounds and colors of recordings or broadcasts. They also operate control panels to select the material's source. Addition from Chammusic: In a professional music studio a recording engineer's job is based around the actual recording of the music group or band. For example they would select and set up the microphones for a drum kit recording // do a soundcheck on the setup // actually supervise the recording // In a lot of studios the engineers also play an important role in actually mixing the recorded tracks as well - use of compression, EQ, reverb, stereo field + much more to help blend together the individual tracks.

The biggest lathe in the world belongs to ESCOM South Africa and was made by Waldrich-Siegen. It has a swing of 4.78 meters, a 38 meter bed, a workpiece weight of 330 tons and the machine weight is 458,6 tons.

you will need a good attitude and open to ideas

advancement in roller skates has changed dramatically. when roller skates were invented, they were something like this: a wooden plate resting on two sticks attached with wheels. as scince and technology changed, roller skates also strted to develope. around 1980's the new model of roller skates came out. this time it was much stable and quicker than the previous ones. those skates used ball bearings fitted in the wheels. the top was made of metal. these days they are more advanced. they still use ball bearings, metal top but added with a fluid, which allows to gain a quick and fast speed.

Sound is the oscillation of pressure through a medium and is measured in decibels.

Yes; the acceleration is zero when the velocity is at its maximum, that is, at the equilibrium position. Since the force and hence the acceleration always act TOWARDS the equilibrium position (because it's a restorative force), then the force and acceleration must change their sign as the mass crosses the e.p., and therefore must be zero instantaneously at the e.p.
