the equation
Based on the equation of state, the other thermodynamic properties such as the enthalpy, entropy and heat capacity at constant pressure are estimated by the residual function method and the fugacity coefficient method respectively.
      
An apparently linear correlation was observed between the ratio of ΔρP/ΔCOD and pH of the solution, and the equation between them was obtained in this study.
      
The basic theorems guarantee existence of at least one cycle and present simple additional general conditions for existence of a one-parametric continuum of different cycles in the equation.
      
For the equation x(t) = εx(t) (1-(1/τ) ∫t-θ-τt-θx(u)du), ε >amp;gt; 0, θ >amp;gt; 0, τ >amp;gt; 0, conditions for the stability of a nonzero stationary solution under small perturbations are determined.
      
In the framework of the general problem for clarifying the stability of the zero solution of the equation x(n) = a1x(n - m) - a2x(n - k) with delays k and m, some partial problems are solved.
      
The problem is posed as a minimization problem of terminal quadratic quality functional on solutions to a linear equation that describes plate vibrations with controls in the right-hand side of the equation.
      
For the estimation error under permanent perturbations where the matrix of the linear part is time-dependent, the zero solution of the equation system was proved to be stable.
      
Relaxation of original optimization problems, namely, a sequence of perturbed problems with vanishing perturbations (the right-hand side of the equation and initial conditions) is proposed.
      
Abstarct-The relationship between oxygen consumption and soft tissue weight in the Gastropoda class (according to the obtained and published data) is expressed by the equation with coefficientsa = 0.71 and k = 0.78.
      
The mass-specific rate of oxygen consumption proved to decrease with mussel age according to the equation:
      
The responses to phenylephrine, noradrenaline, adrenaline, clonidine (α-agonists), and isopropylnoradrenaline (β-agonist) corresponded to the equation p = (PmAn)/(EC50n + An) (1) with n = 1 and n = 2, respectively.
      
The obtained data were approximated by the equation of finite growth.
      
For description of experimental kinetic curves and calculation of cation diffusion coefficients, the equation for ion diffusion into a cylinder of infinite length was used.
      
The equation is derived for the coordinates of maximum and minimum of aggregate formation work on the aggregation number axis arising with an increase in the concentration of micellar solution.
      
The resultant equation for the steady-state nucleation rate has the same form as the equation of the classical theory but contains the work of the thermodynamically irreversible droplet formation.
      
It is transformed into the equation of the classical theory if the clusters have the same temperature as the gaseous phase.
      
The form of this equation is similar to the equation of heat propagation in a moving medium in the presence of heat sources and sinks.
      
The sorption is characterized by Langmuir isotherms and described by the equation of localized stoichiometric sorption.
