Causes of T-Wave Abnormality on an EKG. Abnormal T-Waves on an EKG aren't necessarily an indicator of a problem. However, they could cause your doctor to want to do further testing. The heart has its independent electrical systemâ a network of nerves located throughout all its chambers, which mediate electrical impulses that enable chambers to contract in a synchronized rhythm and sequence.
Chronometric definition, a timepiece or timing device with a special mechanism for ensuring and adjusting its accuracy, for use in determining longitude at sea or for any purpose where very exact measurement of time is required. See more.
Gas chromatography is a powerful means of performing qualitative and quantitative measurements of complex mixtures of volatile substances. In this experiment you will use gas chromatography for quantitative analysis of complex mixtures and determine parameters used to optimize the separation.he number of theoretical plates, n, is a dimensionless number, which is related to the ratio between the retention time, tr, and the width of the peak containing the compound. If the peaks are reasonably symmetric, it can be assumed that they are Gaussian in shape.
