Hypokalemia occurs when the bloodâs potassium levels are too low. A normal level of potassium is 3.6-5.2 millimoles per liter. Levels below 3.6 are considered low. Anything below 2.5 millimoles per liter is very low (Mayo Clinic). Potassium is an electrolyte.
This means that when you buy a yard of fabric youâre getting 1 yard x the width of the fabric (usually measured in inches). The most common widths of fabrics are 36â³, 45â³, 54â³, 60â³, 72â³, and 118â³. Be sure you know what the usuable widths are as some fabrics have borders.
1 A stiff material has a high Young's modulus and changes its shape only slightly under elastic loads (e.g. diamond). 2  A flexible material has a low Young's modulus and changes its shape considerably (e.g. rubbers). A flexible material has a low Young's modulus and changes its shape considerably (e.g. rubbers). 2  A stiff material requires high loads to elastically deform it-not to be confused with a strong material, which requires high loads to permanently deform (or break) it.
