Electroacoustic phenomena arise when ultrasound propagates through a fluid containing ions . It moves these ions. This motion generates electric signals because ions have electric charge . This coupling between ultrasound and electric field is called electroacoustic phenomena. Fluid might be a simple Newtonian liquid , or complex heterogeneous Dispersion chemistry dispersion , emulsion or even a porous body. There are several different electroacoustic effects depending on the nature of the fluid. Ion Vibration Current Potential IVI , an electric signal that arises when an acoustic wave propagates through a Homogeneous chemistry homogeneous fluid. Streaming Vibration Current Potential SVI , an electric signal that arises when an acoustic wave propagates through a porous body in which the pores are filled with fluid. Colloid Vibration Current Potential CVI , an electric signal that arises when ultrasound propagates through a heterogeneous fluid, such as a Dispersion chemistry dispersion or emulsion . Electric Sonic Amplitude ESA , the inverse of CVI effect, in which an acoustic field arises when an electric field propagates through a heterogeneous fluids. Ion Vibration Current Historically, the IVI is the first known electroacoustic effect. It was predicted by Debye in 1933 ref Debye.P. A method for the determination of the mass of electrolyte ions J.

Speech and Phenomena And Other Essays on Husserl s Theory of Signs is a book by French philosopher Jacques Derrida . It was published in 1967 alongside Of Grammatology and Writing and Difference . Speech and Phenomena is Derrida s most well known work on the phenomenology of Edmund Husserl . The book puts forward a broad argument concerning Husserl s phenomenological project as a whole in relation to a key distinction in Husserl s theory of language in the Logical Investigations and how this distinction relates to his description of internal time consciousness. Derrida commented that Speech and Phenomena is the essay I value the most ref Derrida, J., 1981. Positions. Trans. A. Bass. Chicago Chicago UP, p. 13. ref and it is widely considered one of his most important philosophical works. The book is an important articulation of Derrida s mature relationship to Husserl and develops key discussions of the terms deconstruction and diff rance . Derrida s Work on Husserl Speech and Phenomena is the culmination of a long period of study on the phenomenology of Edmund Husserl that Derrida began with his 1953 54 masters thesis The Problem of Genesis in Husserl s Phenomenology .

Unreferenced date December 2006 In astronomy , secular phenomena are contrasted with phenomena observed to repeat periodically. In particular, astronomical ephemeris ephemerides use secular to label the longest lasting or non oscillatory perturbations in the motion of planets, as opposed to periodic perturbations which exhibit repetition over the course of a time frame of interest. Most of the known perturbations to motion in stable, regular, and well determined dynamical systems tend to be periodic at some level, but in many body systems, chaos chaotic dynamics result in some effects which are one way for example, planetary migration . Depending on what time frames are considered, perturbations can appear secular even if they are actually periodic. An example of this is the Axial precession astronomy precession of the Earth s axis considered over the time frame of a few hundred or thousand years. When viewed in this time frame the so called precession of the equinoxes can appear to mimic a secular phenomenon since the axial precession takes 25,771.5 years and monitoring it over a much smaller timeframe appears to simply result in a drift of the position of the equinox in the plane of the ecliptic of approximately one degree every 71.6 years.

In physics , critical phenomena is the collective name associated with the physics of critical point thermodynamics critical point s. Most of them stem from the divergence of the correlation length , but also the dynamics slows down. Critical phenomena include scaling relations among different quantities, power law divergences of some quantities such as the magnetic susceptibility in the ferromagnetism ferromagnetic phase transition described by critical exponent s, universality dynamical systems universality , fractal behaviour, ergodicity breaking. Critical phenomena take place in second order phase transition , although not exclusively. The critical behavior is usually different from the Mean field theory mean field approximation which is valid away from the phase transition, since the latter neglects correlations, which become increasingly important as the system approaches the critical point where the correlation length diverges.

Electrokinetic phenomena are a family of several different effects that occur in heterogeneous fluids or in porous bodies filled with fluid. The term heterogeneous here means a fluid containing particles. Particles can be solid , liquid or gas bubbles with sizes on the scale of a micrometre micrometer or nanometer . There is a common source of all these effects the so called double layer interfacial interfacial double layer of charges. Influence of an external force on the diffuse layer generates tangential motion of a fluid with respect to an adjacent charged surface. This force might be electric , pressure gradient , concentration gradient , gravity . In addition, the moving phase might be either continuous fluid or dispersed phase . Various combinations of the driving force and moving phase determine various electrokinetic effects. Following Fundamentals of Interface and Colloid Science by Lyklema 1995 , the complete family of electrokinetic phenomena includes electrophoresis , as motion of particles under influence of electric field electro osmosis , as motion of liquid in porous body under influence of electric field diffusiphoresis , as motion of particles under influence of a chemical potential gradient capillary osmosis , as motion of liquid in porous body under influence of the chemical potential gradient sedimentation potential , as electric field generated by sedimenting colloid particles streaming potential current , as either electric potential or current generated by fluid moving through porous body, or relative to flat surface colloid vibration current , as electric current generated by particles moving in fluid under influence of ultrasound electric sonic amplitude ... descriptions of electrokinetic phenomena in many books on colloid and interface science ref ..., B.V. 1974 Electrokinetic Phenomena , J.
