background: healthy nutrition especially the energy intake and the essential nutrient in female student is so important. this study aimed to assess micro and macro nutrient intakes in female students of isfahan university of medical sciences.  methods: this cross-sectioned study was carried out on 100 female students aged between 18 to 25 years old in 1387-1388. anthropometrics measures were pe...

Soft x rays are generated when low-energy electron beams traverse a solid-state superlattice. We investigate the influence of x-ray absorption and electron scattering losses on the maximum power radiated, the required electron energy, and the optimum total thickness of the superlattice. We show that a moderate increase in the electron-beam energy compensates for the losses due to photoabsorptio...

We present accurate ab initio numerical solutions of the full Schrödinger equation for the electron-impact ionization of hydrogen near threshold using the propagating exterior complex scaling method. They provide strong support for the Wannier threshold law [Phys. Rev. 90, 817 (1953)], giving sigma proportional to E(1.122+/-0.015), and also give the energy dependence of the electrons' angular d...

A three-state calculation of electron-impact excitation of formaldehyde to the a ' A 2 and A ' A 2 states is carried out using the Schwinger multichannel variational method. The integral and differential cross sections so obtained agree fairly well with theoretical results obtained using the complex Kohn method. Though agreement between the calculated integral cross section and the single avail...

The absolute total cross-sections for electron scattering on SiCl4 molecules have been measured in two distinct electron-transmission experiments, in Gdańsk and in Trento laboratory, for impact energy ranging from 0.3 to 250 eV and from 75 to 4000 eV, respectively. The e–SiCl4 total cross-section function shows two very distinct resonant-like features: the strong peak at 1.9 eV and much broader...

Vertical alignment of liquid crystal (LC) was achieved in an easy and effective way: in situ photopolymerization of dodecyl acrylate (DA) monomers initiated by polyimide based on 3,3′,4,4′-benzophenonetetracarboxylic dianhydride and 3,3′-dimethyl-4,4′-diaminodiphenyl methane (BTDA-DMMDA PI). The alignment behavior and alignment stabilities were characterized by a polarizing optical microscope (...

WIGNER HIGH-ELECTRON-CORRELATION REGIME OF NON-UNIFORM DENSITY SYSTEMS: A QUANTAL-DENSITY-FUNCTIONAL-THEORY STUDY by DOUGLAS M. ACHAN Advisor: Prof. Lou Massa The Wigner regime of a system of electrons in an external field is characterized by a low electron density and a high electron-interaction energy relative to the kinetic energy. The low correlation regime is in turn described by a high el...

The (well-known) quantum mechanical expression for the stress tensor is derived and applied to obtain a formula for the pressure in the average-atom model. This average-atom pressure formula reduces to the (well-known) expression for the pressure in a classical free-electron gas when the average-atom continuum wave functions are replaced by free-electron wave functions. 1 Derivation We start wi...

We theoretically study quantum transport through a dot coupled to Majorana bound states confined at the ends of topological superconducting nanowire. The superconductor forms loop and is threaded by tunable magnetic flux, which allows one control electron in system. In particular, we investigate phonon-assisted properties device when central interacts with single long-wave optical phonon mode. ...
