xj integer (for some or all j = 1,2,...,n). This problem is called the (linear) integer-programming problem. It is said to be a mixed integer program. when some, but not all, variables are restricted to be integer, and is called a pure integer program when all. decision variables must be integers. As we saw in the preceding chapter, if the constraints are of a network.
Anion gap: A measurement of the interval between the sum of routinely measured cations minus the sum of the routinely measured anions in the blood. The anion gap = (Na+ + K+) - (Cl- + HCO3-) where Na-is sodium, K+ is potassium, Cl-is chloride, and HCO3- is bicarbonate. The anion gap can be normal, high, or low.
Osmolar Gap. The Osmolar Gap is another important diagnostic tool that can be used in differentiating the causes of elevated anion gap metabolic acidosis. The major osmotic particles in plasma are Na+ , Cl- , HCO3-, urea and glucose and as such, plasma osmolarity can be estimated as follows:he Osmolar Gap is another important diagnostic tool that can be used in differentiating the causes of elevated anion gap metabolic acidosis.
