Spatially separated electron donors and acceptors in sediment can be exploited by the so-called “cable bacteria.” Electric potential microelectrodes (EPMs) were constructed to measure the electric fields that should appear when cable bacteria conduct electrons over centimeter distances. The EPMs were needle-shaped, shielded Ag/AgCl half-cells that were rendered insensitive to redox-active speci...

Energy efficiency potential studies are being used by policymakers to inform decisions from approval of utility rate cases to developing legislation requiring energy efficiency supply some percentage of future consumption (in most cases, the ‘‘energy’’ is limited to ‘‘electricity generating sources’’). T his article seeks to provide a preliminary discussion of commonalities and differences in e...

Gradients of many kinds have been described in a variety of living organisms, including invertebrates as well as vertebrates. The extensive studies of Child and his co-workers have shown rather wide differences in physiological activity between apical and basal poles in certain invertebrates and between head and tail in longitudinally organized animals. The rates of 02 consumption and CO2 forma...

Inverse problems and inverse analyses, which deal with estimation of inputs or source from outputs or results, have been receiving increasing attention in various fields of science and engineering. A reasonable classification of the inverse problems is described. The nature of inverse problems and difficulties encountered in the inverse analyses are discussed. Typical inversion analysis schemes...

When a piezoelectric film is glued on the surface of a structure member subjected to mechanical load, a distribution of electric potential is induced. In the existence of defects in the member, a characteristic variation of electric potential is observed. Based on this phenomenon, the passive electric potential CT (computed tomography) method is developed for detecting and identifying defects i...

In order to develop a novel n-in-p radiation-tolerant silicon microstrip sensor with a p-stop structure, surface structures are systematically analyzed for variations in the width, position, and multiplicity of p-stops. With the help of technology CAD (TCAD) simulation, three dynamics are quantitatively investigated: the dependence of the electric potential of the p-stops on the width of the p-...

In this paper, a radially piezoelectric functionally graded rotating disk is investigated by the analytical solution. The variation of material properties is assumed to follow a power law along the radial direction of the disk. Two resulting fully coupled differential equations in terms of the displacement and electric potential are solved directly. Numerical results for different profiles of i...

In this paper, we proposed a 2-D analytical model for electrical characteristics such as surface potential, electric field and drain current of Silicon-on-Insulator Tunnel Field Effect Transistor (SOI TFETs) with a SiO2/High-k stacked gate-oxide structure. By using superposition principle with suitable boundary conditions, the Poisson’s equation has been solved to model the channel r...

Background: Recently, ultrasonic neuromodulation research has been an important and interesting issue. Ultrasonic neuromodulation is possible by the use of low-intensity transcranial focused ultrasound (tFUS) to stimulate or inhibit the neural structures. The primary capability of this method is the improvement in the treatment progress of certain neurological and psychiatric disorders noninvas...
