## constant

The annual payment required to pay the principal and interest due on a \$1 loan for a specified repayment term at a specified interest rate.Before the widespread availability of computers and extremely affordable financial calculators,it was common to use mortgage constant tables to calculate monthly payments. One would refer to the table for the proper loan term, such as 30 years, and then within that table find the loan constant for the anticipated interest rate. See the following example. The constant is the monthly payment on \$1. To find out your own monthly payment, you multiply the constant by the number of dollars in your loan, and the answer is what your monthly payments would be.

But the order of the association constant varies for compounds at varying pH values is slightly different.
This model was verified by experimental results, which helped to determine the microscopic parameters, association constant [K.sub.ass], and apparent diffusion coefficient [D.sup.*], related to the formation of the entity (ST) and its diffusion through membrane organic phase.
This moderate interference of DHEA in the aBT compared with 5-diol is to be expected with the lower association constant of DHEA for SHBG (66 x [10.sup.6] L/mol) (7).
In the original model (Alboudwarej et al., 2002), it was assumed that the association constant is the same for all "reactions"; that is, i = 1.
In order to explain the varying polymerization rates, the association constants for each complex were determined, whereupon complexation of each ferrocene derivative with dichloromethane was found to be more facile than similar complexation with benzyl chloride due to steric considerations.
The association constants for 4-HP2OTP are found to be 0.7845 ([+ or -]0.0005), 0.7185 ([+ or -]0.0005), 0.7305 ([+ or -]0.0005) in 1,4-dioxane, DMSO and DMF respectively.
The value of the enhanced fluorescence is dependent on the concentration of the added H [30, 31], as shown in the following equation: where F 0 is the fluorescence intensity of G in the absence of H, F is the observed fluorescence intensity at each H concentration tested, F is the enhancement when 100% of G is complexed, and K is the equilibrium association constant for the 1:1 complexation.
The association constant [K.sub.a] was directly obtained from the intercept/slope ratio.
In water, the ligand 6 binds fluoride with the association constant K > 3500 [M.sup.-1], in its hexaprotonated form.
The mole fraction based association constant [K.sub.y] is related to activity based association constant K by the following equation (Walas, 1984):
These calculations depend on a proper estimation of the association constant for binding of testosterone to SHBG ([k.sub.t]) and albumin ([k.sub.at]).
