  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.

Introduction</title><p>There is a rich history of quantum mechanics that investigates wave-particle duality using light [<xref ref-type="bibr" rid="scirp.72551-ref1">1</xref>] [<xref ref-type="bibr" rid="scirp.72551-ref2">2</xref>] . We derive a one dimensional wave equation in the context of particle movement [<xref ref-type="bibr" rid="scirp.72551-ref3">3</xref>] . This equation has extensively been studied beginning with work proposed by D’Alembert [<xref ref-type="bibr" rid="scirp.72551-ref4">4</xref>] . 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 Schr&#246;dinger’s equation [<xref ref-type="bibr" rid="scirp.72551-ref2">2</xref>] . 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.</p><p>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 [<xref ref-type="bibr" rid="scirp.72551-ref2">2</xref>] . Furthermore, this spin-off flux is deterministic. However, other researchers consider a probabilistic view of the quantum state [<xref ref-type="bibr" rid="scirp.72551-ref2">2</xref>] [<xref ref-type="bibr" rid="scirp.72551-ref5">5</xref>] . The secondary saturation movement in the concentration-time space is used to investigate the behaviour of the wave [<xref ref-type="bibr" rid="scirp.72551-ref6">6</xref>] . 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 [<xref ref-type="bibr" rid="scirp.72551-ref1">1</xref>] [<xref ref-type="bibr" rid="scirp.72551-ref7">7</xref>] . 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.</p><p>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 [<xref ref-type="bibr" rid="scirp.72551-ref8">8</xref>] . The system evolves with time. There are two forms of flux the conductivity and diffusivity.</p></sec><sec id="s2"><title>2. Methods</title><p>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.</p>Derivation of Advection Kinetic Flow for the Secondary Saturation Movement Due to Tension<p>Consider <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x2.png" xlink:type="simple"/></inline-formula> the secondary saturation movement at time t and concentration x-(tension-driven transportation inducing measure) in the blood. The variable <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x3.png" xlink:type="simple"/></inline-formula> is also a measurement of tension density of movement. In addition, the variable <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x4.png" xlink:type="simple"/></inline-formula> is taken to denote the (vertical) displacement at time t of the concentration <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x5.png" xlink:type="simple"/></inline-formula> 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 [<xref ref-type="bibr" rid="scirp.72551-ref8">8</xref>] . The following proposition is made that the amount of</p><p>tension advective conductivity flux of solution particle <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x6.png" xlink:type="simple"/></inline-formula> is the difference</p><p>between <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x7.png" xlink:type="simple"/></inline-formula> (that amount of tension advective conductivity flux which is generated by movement density <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x8.png" xlink:type="simple"/></inline-formula> (obtaining in the process of solution formation)) and <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x9.png" xlink:type="simple"/></inline-formula> (an already existing constant (base) amount of tension advective conductivity flux (primarily obtaining in the independent of solute of x, solvent state)).

Conclusions</title><p>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 [<xref ref-type="bibr" rid="scirp.72551-ref6">6</xref>] [<xref ref-type="bibr" rid="scirp.72551-ref8">8</xref>] . A wave has generally slower movement flux components relative to gradient driven</p><fig id="fig2"  position="float"><label><xref ref-type="fig" rid="fig2">Figure 2</xref></label><caption><title> Components of the spin-off diffusivity flux in time</title></caption><graphic mimetype="image"   position="float"  xlink:type="simple"  xlink:href="http://html.scirp.org/file/2-1720743x129.png"/></fig><fig id="fig3"  position="float"><label><xref ref-type="fig" rid="fig3">Figure 3</xref></label><caption><title> Summary scatter time-matched plot of the relationship between the following variables <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x131.png" xlink:type="simple"/></inline-formula> and <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x131.png" xlink:type="simple"/></inline-formula><inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/2-1720743x132.png" xlink:type="simple"/></inline-formula> for patient P informed by Equations (13), (14) and (15)</title></caption><graphic mimetype="image"   position="float"  xlink:type="simple"  xlink:href="http://html.scirp.org/file/2-1720743x130.png"/></fig><p>movement flux components [<xref ref-type="bibr" rid="scirp.72551-ref8">8</xref>] . There have been several experiments that support De Broglie’s assertions [<xref ref-type="bibr" rid="scirp.72551-ref2">2</xref>] . This work removes the notion of tracking the wave using location with the aid of a probability distribution derived from Schr&#246;dinger [<xref ref-type="bibr" rid="scirp.72551-ref5">5</xref>] . It proposes a different space related to kinetic solubility of a solution particle to track it’s wave [<xref ref-type="bibr" rid="scirp.72551-ref6">6</xref>] .</p><p>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 [<xref ref-type="bibr" rid="scirp.72551-ref8">8</xref>] . The heat (diffusion) and wave equations are two fundamental equations [<xref ref-type="bibr" rid="scirp.72551-ref3">3</xref>] [<xref ref-type="bibr" rid="scirp.72551-ref9">9</xref>] . They describe two forms of advective movements. The heat and wave equations are derived from gradient and tension forms of movement respectively.</p></sec><sec id="s5"><title>Acknowledgements</title><p>The author would like to thank the following; C.
