Experiments were undertaken to demonstrate and characterize specific receptors for epidermal growth factor (EGF) in mammary glands of female BALB/c mice in various physiological states. The results of an in vitro desaturation technique are also presented which allow estimation of the total EGF-binding sites per mg membrane protein. Binding of the ligand… (More)

The paper proposes a solution for the numerical simulation of the <sup>15</sup>N isotope distributed parameter separation process. In order to simulate the separation process, the matrix of partial derivatives of the state vector method, associated with Taylor series, is used. Also, an alternative form of a partial differential equation, of second order… (More)

In this paper, a variant for the pH control of the residual water from a foundry is presented. The blunting process of the residual water, being a distributed parameters one, is modeled using equations with partial derivatives. For the numerical simulation is used a method based on the matrix of the partial derivatives of the state vector (Mpdx) associated… (More)

In this paper, an application of the analogical modeling and numerical simulation of the technical processes through the matrix of partial derivatives of the state vector (M<sub>pdx</sub>) associated with Taylor series is presented. The residual water blunting process is modeled as a distributed parameters process through the usage of equations with partial… (More)

The kinetics of reaction between Cu<sup>2+</sup> and S<sub>2</sub>O<sub>3</sub> <sup>2-</sup> and formation of an intermediate complex, CuS<sub>2</sub>O<sub>3</sub>, are investigated. The kinetics of fading away of the color of this complex has been traced spectrophotometrically using a stopped-flow apparatus. The experimental reaction order is consistent… (More)

In this paper, a solution for the pH control of the residual water is presented. The blunting process is treated as a distributed parameter one, its model being expressed using equations with partial derivatives. The modeling-simulation procedure is based on the matrix of partial derivatives of the state vector associated with Taylor series, method that… (More)

A solution for the pH control of the residual water in an industrial blunting system is proposed. The technological process associated to the blunting system is decomposed in four sub-processes connected in series and in parallel, each of them being a distributed parameter one. The mathematical models of the sub-processes are expressed using partial… (More)

It is presented the numerical simulation of a control system, with PID algorithm, for a process modeled through a partial differential equation of second order (PDE II·2), with respect to time (t) and to a spatial variable (p). The details of using the PID control are pointed out, for an example of a system which contains a process with PDE… (More)
