qualitative and quantitative analyses of hospital and municipal solid waste are necessary for selecting the best and most appropriate method of health care collection, storage, transportation and disposal of this kind of wastes. quantitative and qualitative analyses of hospital and municipal wastes have been studied in ahwaz city during spring 1996. the amount of solid wastes in five regions of...

in this article, the crystallization of polyethylene is investigated by the modified weighted density approximation. also, a direct correlation function of polyethylene based on the rism theory is used. the free energy of a polyethylene is calculated using the density functional theory. the crystallization and also the solid and liquid densities of polyethylene are calculated and compared with ...

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...

We present netDFT: JAVA Density Functional Theory, a Java program to solve the KSDFT equation using pseudopotential method get solid’s band structure and total energy. netDFT provides framework for testing XC functional prototypes academics. can also be used as tool study algorithms equations. The calculation of energy agrees with results obtained by Quantum Espresso.

We present a first-principles method @called spherical self-consistent atomic deformation ~SSCAD!# for calculating the energy per unit cell in ionic crystalline solids. SSCAD is a density-functional method using the local-density approximation ~LDA!. Wave functions are localized about each ion, resulting in a single-particle Schrödinger’s equation for each ion. To simplify the calculation, we s...

We show through rigorous derivation and experimental support that the dynamic effective mass density of an inhomogeneous mixture, used in the prediction of wave velocities in the long wavelength limit, can differ from the static version--the volume average of the component mass densities. The physical reason for this difference is explained. The dynamic mass density expression, first derived by...
