air pollution is one of the most challengeable problems in the asalouyeh zone. in order to reduce the air pollutants emission and their effects it is necessary to recognize the amount and spatial dispersion of air pollutants. hence in this paper, evaporative losses of the stored liquids from 16 tanks of an oil company in asalouyeh zone, are determined using tanks 4.0.9d and then dispersion of v...

Melt dispersion experiments with lateral failure in the bottom head were carried out in a 1:18 scaled annular cavity design under low pressure conditions. Water and a bismut-alloy were used as melt simulant material and nitrogen as driving gas. With lateral breaches the liquid height in the lower head relative to the upper and lower edge of the breach is an additional parameter for the dispersi...

We study theoretically the properties of the interacting Dirac liquid, a novel three-dimensional many-body system which was recently experimentally realized and in which the electrons have a chiral linear relativistic dispersion and a mutual Coulomb interaction. We find that the “intrinsic” Dirac liquid, where the Fermi energy lies exactly at the nodes of the band dispersion, displays unusual F...

We demonstrated micro counter-current flow in a glass microchip utilizing surface modification patterning method to control surface tension. In order to visualize the micro counter-current flow, fluorescent microparticle dispersion solutions were observed by fluorescence microscopy. When the flow volume ratio of water and organic solution was changed, the switching point of flow direction was o...

We demonstrate highly efficient pulse stretching in Er(3+)-doped femtosecond mode-locked fiber lasers by tailoring cavity dispersion using an intracavity short-pass edge filter. The cavity dispersion is preset at around zero to obtain the shortest pulsewidth. When the cutoff wavelength of the short-pass edge filter is thermo-optically tuned to overlap the constituting spectral components of mod...

A solid-state broadband beam deflector is described. This non-mechanical system steers spatially coherent broad band light to a common location in the far field. The components include a liquid crystal grating and achromatic Fourier transformer. The liquid crystal grating employs a polarization modulation scheme which produces a wavelength independent phase shift. The achromatic Fourier transfo...

We propose consistent scaling of solitary waves on inertia-dominated falling liquid films, which accurately accounts for the driving physical mechanisms and leads to a self-similar characterization of solitary waves. Direct numerical simulations of the entire two-phase system are conducted using a state-of-the-art finite volume framework for interfacial flows in an open domain that was previous...

Suspensions of clays in organic liquids change considerably in theological character from liquid to liquid or when additions of a second liquid are made; thus, for example when about 15 per cent. volume of ethyl alcohol was added to a dispersion of a sample of bentonite in water the specific viscosity and thixotropy (as measured 9 by rate of the sol-->gel transition) increased to a maximum in s...

Cystic fibrosis is a life-shortening genetic disease that affects the respiratory, digestive and reproductive systems. Though it manifests a variety of symptoms, it is most notably characterized by chronic pulmonary infections that ultimately lead to respiratory failure and premature death. Recent research has focused on developing inhaled aerosol antibiotics to treat such infections; however, ...

Gas hydrate growth kinetics was studied at a pressure of 90 bars to investigate the effect of temperature, initial water content, stirring rate, and reactor size in stirred semi-batch autoclave reactors. The mixing energy during hydrate growth was estimated by logging the power consumed. The theoretical model by Garcia-Ochoa and Gomez for estimation of the mass transfer parameters in stirred ta...
