what does a nerve conduction test show | The speed of the response is called the conduction velocity. The same nerves on the other side of the body may be studied for comparison. When the test is done, the electrodes are removed. Nerve conduction studies are done before an EMG if both tests are being done.Nerve conduction tests may take from 15 minutes to 1 hour or more, depending on how many nerves and muscles are studied.ormal: The EMG recording shows no electrical activity when the muscle is at rest. There is a smooth, wavy line on the recording with each muscle contraction. The nerve conduction studies show that the nerves send electrical impulses to the muscles or along the sensory nerves at normal speeds, or conduction velocities. | A nerve conduction study (NCS) is a medical diagnostic test commonly used to evaluate the function, especially the ability of electrical conduction, of the motor and sensory nerves of the human body. nerve conduction study (NCS) is a medical diagnostic test commonly used to evaluate the function, especially the ability of electrical conduction, of the motor and sensory nerves of the human body. | eng_Latn | 3,302 |

what does the mass air flow do | The mass air flow (MAF) sensor measures the mass of the air entering the engine. Because air mass varies with air temperature (cold air is denser than warm air), measuring air mass provides the PCM with a very acurate way of determining the correct amount of fuel to obtain the ideal fuel/air mixture.fter you clean the mass air flow sensor make sure to reset the check engine light.

Your mass air flow sensor or âMAFâ detects the volume of air as it enters your engine by heating up a thin wire or resistor. The computer in your car then measures electrical resistance through the MAF as the air flowing through the sensor cools its components down.

Temporal artery thermometers can record a person's temperature quickly and are easily tolerated. | A pressure of 100 mm Hg, for example, would be enough to force the mercury column upward for a distance of 100 mm. To measure arterial blood pressure, the cuff of the sphygmomanometer is usually wrapped around the arm so that it surrounds the brachial artery. Air is pumped into the cuff until the cuff pressure exceeds the pressure in that artery. As a result, the vessel is squeezed closed, and its blood flow stopped. | eng_Latn | 3,330 |

what does throttle body in car mean? | What is the Throttle Body all about? For a car to run smoothly, it needs the proper mixture of air and fuel. The amount of air in the engine is controlled by the air intake system. A throttle body is part of the air intake system that helps control the amount of air that gets into the engine. If the throttle body fails, the engine will not get the proper mixture of air and fuel and the engine may lose power. | What is a throttle body, and why do I need one? I took my 1993 Mazda 626 for its annual state emissions inspection, but the garage couldn't perform the diagnostics because the car was idling too fast. I then took my car to the dealer and had them check out the idle. They told me that my throttle body was shot, but they could get me a new one for $1,000.

If the CO2 gas isn't mixing with another gas flow, it is always 1 million ppm by itself. | From Wikipedia, the free encyclopedia. Pulse-position modulation (PPM) is a form of signal modulation in which M message bits are encoded by transmitting a single pulse in one of possible required time-shifts. This is repeated every T seconds, such that the transmitted bit rate is bits per second. complete PPM frame is about 22.5 ms (can vary between manufacturer). Signal low state is always 0.3 ms. It begins with a start frame (state high for more than 2 ms).

what is pressure mapping | The mean arterial pressure (MAP) is a term used in medicine to describe an average blood pressure in an individual. It is defined as the average arterial pressure during a single cardiac cycle. | The Manifold Absolute Pressure (MAP) sensor is used by the Powertrain Control Module (PCM) for engine load input. The PCM uses this input, as well as others, to calculate the correct amount of fuel to inject into the cylinders. The MAP sensor measures the absolute pressure inside the intake manifold of the engine. At sea level, atmospheric pressure is about 14.7 psi (pounds per square inch). When the engine is off, the absolute pressure inside the intake equals atmospheric pressure, so the MAP will indicate about 14.7 psi. At a perfect vacuum, the MAP sensor will read 0 psi. When the engine is running, the downward motion of the pistons create a vacuum inside the intake manifold (For the purposes of engine control, when a technician says vacuum, what they are really saying is pressure that is less than atmospheric pressure). | eng_Latn | 3,342 |

Now let's say Dumbledore enters his office while Harry was using the Pensieve -- what would Dumbledore see? Is there an answer in the books/canon? | Is the double-slit experiment typically carried out in a vacuum? It is my understanding of the double-slit experiment that when a measuring device is activated, to measure which of the two slits a particle is travelling through, this measuring is responsible for a different outcome than when the device is left off. When the device is left off particles leave an interference pattern, suggesting a single particle (or its wave) interferes with itself; when the device is activated no interference pattern is left, and particles are observed to travel through a single slit. Now, does all this imply that this experiment is typically carried out in a vacuum? If not, how is it that interaction with other particles in the environment of the experiment's set-up are not already influencing the outcome, regardless of whether the measuring device is on or left off? This question may very well be a very naive one, due to my very limited understanding of particle interaction, vacuums and/or physics in general.

what does labview mean | LabVIEW is systems engineering software for applications that require test, measurement, and control with rapid access to hardware and data insights. LabVIEW simplifies hardware integration so that you can rapidly acquire and visualize data sets from virtually any I/O device, whether by NI or a third-party. | Single-ended and differential refer to the reference for a voltage. Single-ended is referred to ground while differential is referred to some other voltage. For a single-ended measurement, the LabJack converts the difference between the voltage at an input and ground. For a differential measurement, the LabJack converts the difference between the voltage at one input and the voltage at another input that is not necessarily ground. | eng_Latn | 3,399 |
