Electrostatic potentials around DNA are obtained by solving the nonlinear Poisson-Boltzmann (PB) equation. The detailed charge distribution of the DNA and the different polarizabilities of the macromolecule and solvent are included explicitly in the calculations. The PB equation is solved using extensions of a finite difference approach applied previously to proteins. Electrical potentials and ...

Quintessential inflation is studied using a string modulus as the inflaton– quintessence field. It is assumed that the modulus crosses an enhanced symmetry point (ESP) in field space. Particle production at the ESP temporarily traps the modulus resulting in a period of inflation. After reheating, the modulus freezes due to cosmological friction at a large value, such that its scalar potential i...

Flue gas conditioning (FGC) systems offer an effective option for control of Particulate Matter (PM) emissions and enhances the performance of the Electrostatic Precipitators (EPs) when using coal of different properties. The increasing environmental awareness and the mandate of the Environmental Protection Agencies (EPA) in various countries to thermal power stations using coal-fired boilers f...

Artificial Neural Networks (ANN) consist an alternative method of solving complex problems. They operate as a “black box” model learning from examples, which is capable of dealing with non-linear problems and predicting results at high speed. An advantage of using ANN is their ability to handle large and complex systems with many interrelated parameters. They seem to simply ignore excess data t...

The molecular structure of 3-methyl 2-vinyl pyridinium phosphate (3M2VPP) has been optimized by using Density Functional Theory B3LYP hybrid functional with 6-311++G (d, p) basis set in order to find the whole characteristics complex. theoretical structural parameters such as bond length, angle, and dihedral angle are determined DFT methods well agreed single crystal X-ray diffraction parameter...

The enterococcal surface protein, Esp, originally found in Enterococcus faecalis, has been associated with increased virulence, colonization, and biofilm formation (2, 3, 5, 6). Recently, a variant esp gene was found in Enterococcus faecium isolates from humans (L. Baldassarri, L. Burtuccini, M. G. Ammendolia, G. Gherardi, and R. Creti, Letter, Lancet 357:1802, 2001; R. J. Willems, W. Homan, J....

A laboratory-scale single-stage electrostatic precipitator (ESP) was designed, built and operated in a wind tunnel. As a "rst step, a series of experiments were conducted to seek the operating conditions for increasing the particle collection e$ciency by varying basic operating parameters including the wire-to-plate spacing, the wire radius, the air velocity, the turbulence intensity and the ap...

Most Enterococcus faecalis and E. faecium are harmless to humans; however, strains harboring virulence genes, including esp, gelE, cylA, asa1, and hyl, have been associated with human infections. E. faecalis and E. faecium are present in beach waters worldwide, yet little is known about their virulence potential. Here, multiplex PCR was used to compare the distribution of virulence genes among ...

In this paper, the stability of a functionally graded magneto-electro-elastic (FG-MEE) micro-beam under actuation of electrostatic pressure is studied. For this purpose Euler-Bernoulli beam theory and constitutive relations for magneto-electro-elastic (MEE) materials have been used. We have supposed that material properties vary exponentially along the thickness direction of the micro-beam. Gov...

The performances of two continuously monitoring mycobacterial culture systems-ESP Culture System II (ESP II; Trek Diagnostics, Inc. , Westlake, Ohio) and BACTEC MGIT 960 (BD Biosciences, Sparks, Md. )-were compared. In addition to both liquid media, all specimens were plated onto Middlebrook 7H11/7H11 selective agar. A total of 3, 151 specimens of all types (56.3% were respiratory specimens) we...
