Others include cancers of the pancreas, stomach, breast, lung, and medullary carcinoma of the thyroid and ovarian cancer.
Screen refresh rate is the number of times an image on any type of monitor or television is reconstructed per second. This is measured in hertz.. (Hz) For example, a TV witâ¦h a refresh rate 60Hz, reconstructs the image you're seeing 60 times every second. Basically, the higher the refresh rate on a tv, the representation of motion will be smoother, and the image will flicker less.
When the refresh rate is set to Low, the data is refreshed every 120 seconds.When the refresh rate is set to Medium, the data is refreshed every 60 seconds. When the refresh rate is set to High, the data is refreshed every 30 seconds. The refresh rate does not impact connectivity verifiers. To set the refresh rate for connectivity verifiers, use the Refresh rate script, available on the (http://www.microsoft.com/). Note that for ISA Server 2006 Enterprise Edition, the refresh rate applies to all connectivity verifiers on all array members, and for ISA Server 2006 Standard Edition, the refresh rate applies to all connectivity verifiers.
