what is the Ks constant in the Monod equation?
half-saturation constant
what is S in the Monod Equation
limiting substrate concentrate
five components of PCR
taq polymerase, template, primer, dNTP, MgCl2
what is an isotherm
relationship between actoivity or equilibrium concentration of the adsorptive and the quantity if adsorbate on the surface at constant temperature
advection vs dispersion
transport of solutes in bulk flow vs
mechanical dispersion, three basic causes
pore size, path length, friction in pore
assumptions for advection-dispersion equation
homogenous/isotropic, saturated, darcys law is valid, flow is steady
