10 Common Signs of an Ear Infection. Ear infections are a lot more common than you might think. Studies actually show that more than 60-percent of head colds turn into an ear infectionâparticularly in babies and toddlers. However, identifying an ear infection in yourself or spotting one in your child is often difficult if youâre not familiar with the symptoms.
Measuring RDS(on) with high-definition oscilloscopes. RDS(on) of MOSFETs is a key parameter for determining the conduction loss in switched-mode power supply applications and is therefore of special interest. When a switching MOSFET is off, it has a high drain-to-source voltage, but when it is turned on the voltage drops to just a few hundred millivolts. A high-resolution oscilloscope is needed to measure these low voltages. Probe compensation and correct probing are also vital for accurate RDS(on) measurements. Your task.
Red blood cell distribution width (RDW-CV or RCDW and RDW-SD) is a measure of the range of variation of red blood cell (RBC) volume that is reported as part of a standard complete blood count. Usually red blood cells are a standard size of about 6-8 Î¼m in diameter. Certain disorders, however, cause a significant variation in cell size. Higher RDW values indicate greater variation in size. Normal reference range of RDW-CV in human red blood cells is 11.5-14.5%. If anemia is observed, RDW test results are often used together with mean corpuscular volume (MCV) results to determine the possible causes of the anemia.
