The deterministic description of a wave of solution particle of efavirenz is given. Simulated pharmacokinetic data points from patients on efavirenz are used. The one dimensional wave equation is used to infer on transfer of vibrations due to tension between solution particles. The work investigates movement using wave analogy, but in a different variable space. Two important movement fluxes of a wave are derived an attracting one identified as tension conductivity and a dispersing one identified as tension diffusivity. The Wave Equation can be used to describe another spin-off movement flux formed induced by vibrations in solution particle.


Partial Differential Equations, Wave, Movement Flux

1. Introduction

There is a rich history of quantum mechanics that investigates wave-particle duality using light [1] [2] . We derive a one dimensional wave equation in the context of particle movement [3] . This equation has extensively been studied beginning with work proposed by D’Alembert [4] . Furthermore, this work supports the hypothesis advanced by Louis de Broglie that all matter manifests a wave like nature. An idea further developed by David Bohm, who postulated that every material particle is accompanied by a field which guides the motion of the particle. This field evolves according to the Schrödinger’s equation [2] . In this work we retain the conventional wave equation. It models the advective entity of a wave and proposes an extension to other components of movement flux which are passive, convective and saturation.

This work derives characterisation of a wave and shows it as a spin-off movement flux that is derived from tension in the vibrations of the solution particle. It is described as a spin-off of a solution particle or the pilot wave [2] . Furthermore, this spin-off flux is deterministic. However, other researchers consider a probabilistic view of the quantum state [2] [5] . The secondary saturation movement in the concentration-time space is used to investigate the behaviour of the wave [6] . The mathematical formulation brings to light an understanding of the wave part of a solution particle. Waves in location and time space have been studied by other researchers [1] [7] . The wave is studied in a different space (concentration-time) and analogies are proposed. A relationship of a wave is derived, with the aid of simulated pharmacokinetic data in-vivo.

In addition, this work shows that a wave is a system with four primary movement components of flux. The total flux at any given concentration is zero. The system formed is similar to that obtained for the one that facilitates exchange of concentration through gradient [8] . The system evolves with time. There are two forms of flux the conductivity and diffusivity.

2. Methods

Simulated projected data on secondary saturation movement, time and concentration was obtained from pharmacokinetic projections made on patients on 600 mg dose of efavirenz considered in Nemaura (2015, 2016). Partial and Ordinary Differential equations are used in the development of models that characterizes wave motion. A statistical Package R, is used to develop nonlinear regression models.

Derivation of Advection Kinetic Flow for the Secondary Saturation Movement Due to Tension

Consider the secondary saturation movement at time t and concentration x-(tension-driven transportation inducing measure) in the blood. The variable is also a measurement of tension density of movement. In addition, the variable is taken to denote the (vertical) displacement at time t of the concentration on the advection string component. The rate at which saturation movement crosses a solution particle is proportional to concentration, time and secondary saturation move- ment of solution particle [8] . The following proposition is made that the amount of

tension advective conductivity flux of solution particle is the difference

between (that amount of tension advective conductivity flux which is generated by movement density (obtaining in the process of solution formation)) and (an already existing constant (base) amount of tension advective conductivity flux (primarily obtaining in the independent of solute of x, solvent state)). The function of proportionality is called the amount of tension advective conductivity flux and is de- noted by The functions and are such that and where is the homogenous concentration mix in the base solvent without solute, thus and where are constants of direct proportionality associated with the tension,


In a homogenous mix, Thus the tension advective conductivity flux

[tension advective conductivity flux in the solvent of a solute of, in the absence of the solute (before mixing)] is constant and Equation (1) reduces to,


Consider a small element of the string (bridge) between the two concentration points and (, small). The total tension advective flux to which this string is subjected to is the tension advective flux exerted at the left end and the advective flux exerted at the right end by the rest of the string.

Let be the angle between and (horizontal direction of components) and be the angle between and Assume since we are looking at small vibrations. It follows that either is close to 0 or

The total vertical tension advective flux acting on the element is


where is the vertical direction of component. We note for close to zero and for close to. For a fixed




From Equations (1)-(5) and the approximation formulas for we obtain the following approximation for the vertical flux on the element of the advective string,


The concentration-time amount of form movement due to tension in the solution

particle bridge is Drawing analogy from Newton’s Second Law to re-

place in (6)





At the limit, the Equation (8) reduces to,


The following result is immediate,



is the secondary saturation tension advective conductivity flux associated with a unit amount of movement in a solution-particle bridge. This reduces to,



The terms,

are secondary saturation tension base-advection diffusivity flux, secondary sa-

turation tension advection diffusivity, and secondary saturation initial or

rest tension advection conductivity flux respectively.

The following relation from Equations (10) and (11) is established between tension advection conductivity and diffusivity fluxes,



It is important to note that is the tension advection conductivity flux.

It is noted that for the following holds at boundary points of spin-off advective conductivity flux: value at rest of spin-off saturation conductivity flux.

The reference spin-off advective flux is investigated and the constituent behaviour is suggested by Equation (16) (Table 3),

We give a summary of tension associated diffusivity, diffusivity flux, and conductivity flux in relation to concentration-time (Figure 3).

4. Conclusions

A wave in this work has been shown to be a spin-off movement flux of a solution particle. It also has the same component characterisation as a solution particle at primary level. It consists of the advective, passive, saturation and convective components [6] [8] . A wave has generally slower movement flux components relative to gradient driven

movement flux components [8] . There have been several experiments that support De Broglie’s assertions [2] . This work removes the notion of tracking the wave using location with the aid of a probability distribution derived from Schrödinger [5] . It proposes a different space related to kinetic solubility of a solution particle to track it’s wave [6] .

Considering a different unique space, we obtain similar characterisation of flux of a wave to that of gradient-driven diffusion. These two are system flux movements in time. A conclusion is reached that these two forms are characterised similar pattern of move- ment [8] . The heat (diffusion) and wave equations are two fundamental equations [3] [9] . They describe two forms of advective movements. The heat and wave equations are derived from gradient and tension forms of movement respectively.
